Utility has completed the req ired SWMP Plan to meet the obligations of the City of
Renton's Western Washingto Phase II Municipal Stormwater Permit.
STAFF RECOMMENDATION:
This is an informational briefi g only.
BACKGROUND:
Federal and state water qualit, laws require a permit for the discharge of stormwater
(Federal Water Pollution Control Act Title 22 United States Code, Section 1251 et seq.,
'State Water Pollution Control tct RCW 90.48).
In 1987, Congress amended the federal Clean Water Act to address municipal
stormwater discharges through the NPDES permits. The Washington,State Department
of Ecology(Ecology) is responsible for issuing and renewing these permits. In 2007,
NPDES Municipal Stormwater(permits were issued in Washington for Phase.I and Phase
II jurisdictions. Phase I permit were issued to large municipalities and county
governments with population over 100,000 (as of the 1990 census). Phase II permits
were issued to smaller governmental entities generally with populations between
10,000 and 100,000. The City hof Renton is covered under Western Washington's Phase
II Municipal Separate Stormwter Sewer System (MS4) NPDES permit(Phase II Permit).
Discharges from MS4s (systems designed to collect and convey stormwater runoff) are
regulated by Ecology under the NPDES program. The municipal NPDES permit seeks to

control or reduce pollutant discharge to the maximum extent practicable, primarily
through programmatic efforts The City is regulated by Ecology as a Phase II permittee.
The Phase II Permit became effective on February 16, 2007, was modified in 2009, and
expired on February 15, 2012. Ecology extended the 2007-2012 Phase II Permit
requirements until July 2013. A new 2013-2018 Phase II Permit with updated
requirements was issued on August 1, 2012, and became effective on August 1, 2013. ,
The Permit requires the City t develop and annually update a SWMP. The Phase ll
`Permit lists specific actions an activities the City must implement through the SWMP,
include the following cornpon nts:
1. A public education and outreach program designed to reduce or eliminate
behaviors and,practices that cause or contribute to adverse stormwater impacts
and encourage the pu lic to participate in stewardship activities.
2. A process for involving the public in the development, implementation and
update of the SWMP.
3. An ongoing illicit discharge detection and elimination program to prevent,
detect, characterize,trI ce and eliminate illicit connections and illicit discharges
into the MS4. ,
4. A program to reduce p Ilutants in stormwater runoff from new development,
redevelopment and co struction site activities.
5. An operation and mai tenance program to prevent or reduce pollutant runoff
from municipal operat ons.
In addition to the five components listed above,the SWMP plan also includes a
discussion of the monitoring and reporting requirements of the Phase II Permit
CONCLUSION:
The Phase II Permit requires that the City prepare written documentation of the SWMP
to inform the public of the planned SWMP activities, and to update that documentation
annually no later than May 31 each year. The City's updated SWMP plan satisfies this
requirement. The SWMP plan is posted on the City's web site along with a request for
public input.

I TRO Una , AN) :ACKGRIUN'i
In 1987, Congress amended the federal Clean Water Act to address municipal stormwater
discharges through the National Pollution Discharge Elimination System (NPDES) permits. In
Washington State, the Washingt41 State Department of Ecology (Ecology) is responsible for
issuing and renewing these permits. In 2007, NPDES Municipal Stormwater permits were issued
in Washington for two groups of permittees: Phase I jurisdictions and Phase II jurisdictions.
Phase I permits were issued to large municipalities and county governments with populations
over 100,000 (as of the 1990 census). Phase II Permits were issued to smaller governmental
entities generally with populations between 10,000 and 100,000. The City of Renton (City) is
covered under Western Washingtpn's Phase II Municipal Separate Stormwater Sewer System
(MS4) NPDES permit (Phase II Permit).
Discharges from MS4s (systems designed to collect and convey stormwater runoff) are
regulated by Ecology under the NPDES program. The municipal NPDES permit seeks to control
or reduce pollutant discharge to the maximum extent practicable, primarily through
programmatic efforts. The City is regulated by Ecology as a Phase II permittee. The Phase II
Permit became effective on February 16, 2007, was modified in 2009, and expired on
February 15, 2012. Ecology exte ded the 2007-2012 Phase II Permit requirements until July
2013. A new permit with update requirements (2013-2018 Phase II Permit) was issued on
August 1, 2012 and became effective on August 1, 2013. For fiscal year 2015 (July 1, 2014,
through June 30, 2015), the City`was charged an annual permit fee of $50,024 by Ecology.
This annual fee will likely increase with future Phase II Permit updates.
The Phase II Permit requires the City to develop a Stormwater Management Program (SWMP).
The SWMP must include the,following components:
1. A public education and o treach program designed to reduce or eliminate behaviors
and practices that cause or contribute to adverse stormwater impacts and encourage
the public to participate in stewardship activities
2. A process for involving the public in the development, implementation, and update of
the SWMP
3. An ongoing illicit discharge detection and elimination (IDDE) program to prevent,
detect, characterize, trace, and eliminate illicit connections and illicit discharges into
the MS4
4. A program to reduce pollutants in stormwater runoff from new development,
redevelopment, and construction site activities
5. An operation and maintenance pan) program to prevent or reduce pollutant runoff
from municipal operations
January' 2015 HERRERA
City of Renton Stormwater Management Program Plan 1
In addition, the Phase II Permit requires that the City prepare written documentation of the
SWMP and update that documentation annually. This SWMP plan satisfies this requirement. In
addition to the five components listed above,,this SWMP plan also includes a discussion of the"
monitoring and reporting requirements of the Phase II Permit. This SWMP plan'also includes a
description of the City's internal coordination mechanisms as required by S5.A.b

An illicit discharge is defined asny discharge into the stormwater system that is not
composed entirely of stormwater, or of non-stormwater discharges allowed as specified in the
Phase II Permit. Illicit discharges may be from a variety.of sources and activities including
illegal dumping, sanitary sewer overflow, swimming pool cleaning, and incidental spills (such
as oil, gas, diesel fuel, paints, or solvents). This section describes the Illicit Discharge
Detection and Elimination (IDDE) Phase II Permit requirements, as well as the City's planned
compliance activities.
13®2018 Phase Ul Per at Requirement

Program designed to prevent, detect, characterize, trace, and eliminate illicit connections
and-illicit discharges into the stormwater system. The specific Phase II Permit requirements
are as follows:
1. Continuing mapping of thi MS4 on an ongoing basis.
2. Publicize a public hotline Pumber for reporting of spills and other illicit discharges;
and track all calls and follow-up actions taken.
3. By February 2, 2018, adopt an updated ordinance that effectively prohibits non-
stormwater, illegal discharges, or dumping into the City's stormwater system to the
maximum extent allowably by state and federal law.
4. ByDecember 31, 2017, om lete field screeningof 40 percent of the stormwater
9 P
system. After December 31, 2017, the City is required to complete field screening on
an average of 12 percent of the stormwater system per year.

Washington State Department of Ecology(Ecology) offer of grant assistance from the Municipal
Stormwater Capacity Grants Program, FY 2013. The 2013 Washington State Legislature
appropriated this pass-through grant funding in Ecology's 2013-2015 Biennial Operating Budget
to assist cities with the implementation of the 2013 NPDES Municipal Stormwater Permit and
for the planning and design of stormwater flow control and/or water quality treatment
projects.
The City is eligible to receive a total of$170,000 Municipal Stormwater Capacity grant funding
from Ecology. The grant funding consists of two parts:
• $50,000 funding will assist the Surface Water Utility and the City to implement
requirements associated with the NPDES Phase II Municipal Stormwater permit.
• $120,000 pre-construction funding will assist with planning and designing activities of
retrofit projects to address pollution from existing development.
The grant funding does not require the local government to match and is 100 percent funded
by the Department of Ecology. Ecology will disburse funds on a cost-incurred basis.
To initiate the agreement process, the completed and signed GAIN must be returned to the
Department of Ecology no later than August 30, 2013. Ecology will mail grant agreements to
recipients for signature during August and September.
Please return the signed GAIN form to Ron Straka, Surface Water Utility, for submission to the
Washington State Department of Ecology before the August 30, 2013 deadline.

Introduction
This document has been prepared to meet the City of Renton's Western Washington
Phase II Municipal Stormwater Permit(Permit) requirement for development of a
Stormwater Management Program(SWMP).
The City's SWMP is designed to develop numerous actions and activities to reduce the
discharge of pollutants from the City's Municipal Separate Storm Sewer System(MS4)
to the maximum extent practicable(MEP)to meet Washington State's All Known and
Reasonable Treatment(AKART)requirements, and protect water quality. This goal is
accomplished by the inclusion of all Permit SWMP components,minimum measures and
implementation schedules into the City's SWMP.
Where the City is already implementing actions or activities called for in the SWMP,the
City will continue those actions or activities regardless of the schedule called for in this
document.
As part of the implementation of the City's SWMP,the City will gather, track,maintain
and use information on anon-going basis to evaluate the SWMP development,
implementation, Permit compliance, and to set priorities. Beginning no later than
January 1, 2009, the City will begin to track the cost(or estimated cost) of development
and implementation of each component of the SWMP.
This document will be evaluated and updated at least annually for submittal with the
City's Annual Report to the Department of Ecology by March 31st each year as required
per the permit. The following document sections are arranged per the Permit
requirements as laid out in section S5.C: This SWMP includes a description of each City
program component per S5:C and additional actions implemented by the City as an extra
to the Permit or as a response to compliance with Total Maximum Daily Load
Requirements (TMDLs).
Department of Ecology Permit Updates (Codified in 2012)
In 2012, the Washington State Legislature and Governor enacted Senate Bill 6406 to give
cities and counties fiscal relief during periods of economic downturn by delaying or
modifying certain regulatory and statutory requirements. Section 313 of the bill modified
RCW 90.48.260 to require that by July 31, 2012, Ecology shall:
(a) Reissue without modification for a term of one year any national pollutant
discharge elimination system municipal stormwater general permit applicable to
Western Washington municipalities first issued on January 17, 2007; and
(b) Issue an updated national pollutant discharge elimination system municipal storm
water general permit for any permit applicable to Western Washington municipalities
first issued on January 17, 2007. An updated permit issued under this subsection
shall become effective beginning August 1, 2013.
March 2013 Page 4
City of Renton Storm 2013 Storm Water Management Plan
Ecology therefore reissued without modifications the 2007-2012 Western Washington
Phase II Municipal Stormwater General Permit to be effective from September 1, 2012
to August 1, 2013.
Permittees subject to the requirements of the 2007-2012 Western Washington Phase II
Municipal Stormwater Permit shall continue to implement their Stormwater Management
Programs developed under the previous permit and all other requirements of the permit
until August 1, 2013, with clarifications listed in the reference table on pages 5-9 of the
reissued permit for the period September 1, 2012 to August 1, 2013.
After an extensive public process, Ecology also reissued the updated 2013 to 2018 Phase
II permit for Western Washingon. It covers at least 80 cities and portions of five
counties with an effective date of September 1, 2012. The updated 2013-2018 permit will
become effective on August 1, 2013. The City of Renton plans on updating the SWMP
to be consistent with the 2013 tO 2018 Permit requirements.

The following SWMP is formatted with permit requirements in regular text type and
italic text is how the City is addressing the permit requirements.
. Section 1 : Development, Implementation and Permit
Compliance (S5.A.3)
The SWMP shall include an ongoing program for gathering, tracking,maintaining, and
using information to evaluate SWMP development,implementation and permit
compliance and to set priorities.
a) Beginning no later than January 1, 2009, each Permittee shall track the cost,or
estimated cost of development and implementation of each component of the
SWMP. This information shall be provided to Ecology upon request.
Using its existing accounting system, the City started an Estimated Cost Tracking
program with the purpose of obtaining an approximated cost of developing and
implementing a SWMP by program components. The program components as
defined by the permit are: Public Education, Public Involvement, IDDE, Control of
Runofffrom Development(Review and Inspection), and Operations and
Maintenance. Under each component, types of activities that the City is likely to
engage in over the current permit cycle were identified. Monitoring and General
Permit Management are possible future components to be included. ,
The City tracks Permit related costs by approximating the expenditures spent from
each City department by extracting out the percentage of NPDES program funds
spent. Essentially, the cost tracking method derives an estimate for each department
division by multiplying the division's annual operating expenditures by the
percentage of division staff time spent of NPDES activities. This method captures the
cost of salaiy'and benefits as well as relative support costs, i.e.facilities, technical
services, and administration supplies. Added to this estimate are CIP costs, i.e.
professional service contracts for storm system inventory mapping and development
of surface water design standards. -
b) Each permittee shall track the number of inspections, official enforcement actions
and types of public education activities as stipulated by the respective program
component. This information shall be included in the annual report.
The City currently has a program for record keeping. This program
highlights specific records.and categorizes the records into three categories as
explained below.
• Category 1 records mainly fall into four components:
o Public Education,
o IDDE,
o Development Review &Inspection, and "
o Operations &Maintenance.
March 2013 = - Page 6

• Categories 2 &3 would be more informal records kept, maintained and
updated by active members of the SWMP program.
• Spill Response Records: Spills are tracked and kept at the City. These spills
are types that may pose an environmental or health hazard.

Section 2: Public Education and Outreach (S5.C..1)
The City's SWMP includes an education program aimed at residents, businesses,
industries, elected officials, policy makers,planning staff and other employees of the
City. The goal of the education program will be to reduce or eliminate behaviors and
practices that cause or contribute to adverse stormwater impacts. The City's education
program may be developed locally or regionally.. -
Permit Requirements
The Phase II Permit(Section Section S5.C1)requires the City's SWMP to include an
education and outreach program covering specified subjects and audiences. Section
S5.C1.a-c lists the following requirements:
• Prioritize and address the target audiences and subject areas listed in the Permit
• based on stormwater issues. •
• Develop education and outreach programs that are designed to reduce or eliminate
behaviors and practices that cause or contribute to adverse stormwater impacts.
• Measure changes in the understanding and adoption of behaviors by the target
audience, and use that information to evaluate past programs, and to direct future
programs.
• Maintain records of public education and outreach activities
Public Education and Outreach Program (S5.C.1.a)
No later than February 16, 2009,the City will provide an education and outreach
program for the area served by its Municipal Separate Storm Sewer System
(MS4). The outreach program will be designed to achieve measurable
improvements in the target audience's understanding of the problem and what
they can do to solve it.
The City of Renton maintains an active public education and outreach program
with a variety of approaches to inform residents, businesses and developers about
ways to prevent stormwater pollution. The program has been developed locally
with input from regional organizations such as the STORM group, King County,
WRIA 8 Salmon Recovery Council, WRIA 9 Watershed Ecosystem Forum, the
Department of Ecology, and the Environmental Protection Agency. The goal of
the education program is to reduce or eliminate behaviors and practices that
cause or contribute to adverse stormwater impacts
Current Activities
The tables below organize Renton's educational program elements to meet Permit
requirements for subject area and target audience. A list with descriptions of
each program element follows the tables.

household hazardous wastes. Tihe program supports proper management, disposal, and
reduction of moderate risk wastes. The Renton Solid Waste Utility has provided
collection of some household hazardous wastes at two (2)special collection events each
year. The recycling events collect oil, antifreeze, oil filters, automotive and Ni Cad
batteries; and refrigerators ana freezers from the public at no cost to the public. This
encourages the proper disposal and/or recycling of the material while helping to
discourage illegal dumping. This regional program of local governments'works to

March 2013 Page 15
City of Renton 2013 Storm Water Management Plan
This program targets alternative lawn care practices with emphasis on reducing or
eliminating pesticides and efficient use of water for gardens. This program will be
maintained as outlined in the Solid Waste Section work plan.
Staffing in 2009 changes required taking a new direction with the Natural Yard Care
program, incorporating those concepts into the City's general Natural Yard Care
program. This program included conducting a 2009 Natural Yard Care workshop, open
to the general public. Approximately twenty-five (25)people attended. Concepts
emphasized included how to reduce reliance on pesticides and chemical fertilizers
through a number of"best practices"for gardening. Additionally, the workshop focused
on backyard composting, and the addition of compost as mulch to the landscape. In
2010, the solid waste program held two (2)special recycle events, and hosted four(4)
Natural Yard Care Workshops. The four Natural Yard Care Workshops held in 2010
are: `Wildlife Friendly Gardening for Natural Pest Control', `Natural Lawn Care',
Rain Wise Gardening'and `Choosing the Right Plant'. These workshops had 66
attendees total, and two workshops were filmed and broadcast on the City of Renton
website and on Renton Cable Channel 21. For 2011, the solid waste program again held
two (2) Special Recycling Events, and sponsored four (4)Natural Yard Care Workshops
including: 'Fall Groundwork', `Start with Soil', `Sustainable Garden Design', and `Love
Your Lawn'. These workshops had 182 attendees total. [Target Audience: General
Public, Homeowners]
The 2012 Natural Yard Care program targeted half of the four workshops on the City's
growing Hispanic population. Attendance at the two English-language workshops
increased significantly from. the 2011 workshops. Attendance at the Spanish-language
workshops was low, however given this was the first year with this focus it is anticipated
that the interest and participation will grow as the City continues to sponsor the Natural
Yard Care program in 2013 and 2014. Workshops for 2012 included: Container
Gardening for Healthy Eating; Pest, Weed, and Disease Control; Fall Gardening
(Spanish); and Gardening without Pesticides (Spanish). [Target Audience: General
Public, Homeowners, Gardeners, Hispanic Community]
Hazardous Waste Reduction: Past household hazardous waste reduction education
program have included providing hands on hazardous waste reductionworkshops to
elementary school classes, and workshops to teach residents how to compost yard waste
using a backyard compost bin and compost food waste using worm bins. Over 1000
backyard and worm compost bins have been distributed to City residents through the
backyard composting program. [Target Audience: General Public, Homeowners]
Integrated Pest Management: The City follows landscaping pesticide use according to
the "Landscape Management Practices Plan"that references City pesticides,
insecticides, and fungicides management program and chemical usage information.

Measurement (S5.C.1.b)
The permit requires that each permittee measure the understanding and adoption
of the targeted behaviors in at least one subject area, with the resulting
measurements used to direct education and outreach programs most effectively, as
, well as to evaluate changes in adoption of the targeted behaviors. Renton's
compliance is'found in the following:
The City is measuring the understanding and adoption of the targeted behaviors
and targeted audiences listed below with specific measurements for each
program. The resulting measurements will be used to direct education and
outreach resources more effectively, as well as to evaluate changes in adoption of
the targeted behaviors:
Target Audience: General Public-Storm Drain Marker Volunteers
Subject Area: Source control BMPs and environmental stewardship actions and
opportunities in the areas of pet waste, vehicle maintenance and landscaping.
Program description: In2010, the City initiated a program to educate the
general public through a volunteer program to install storm drain markers and
(for selected projects) distribute educational flyers to residences in the area of
installation. The markersarelabeled with the Puget Sound Starts Here (PSSH)
logo. The flyers feature an image of the storm drain markers, which helps
residents make the connection between the flyer content and the markers installed
in their neighborhood. The flyer reflects the PSSH message,that individuals can
make a difference by making'small changes to,their daily behaviors. It describes
10 things that individuals can do to prevent stormwater pollution, including
categories of car maintenance,pet waste management and yard care.
March 2013 Page 18
City of Renton Storm 2013 Storm Water Management Plan
Program Measurement.1 The effectiveness of the Storm Drain Marker Volunteer
program to encourage the targeted audience to adopt changes is measured by
surveying the volunteergroups. The volunteer participants complete a survey at
the beginning of the project, before they are given education on storm drain
pollution prevention and the purpose of the storm drain marker and informational
flyer distribution project. At the end of the project the participants complete a
second survey.. City staff compares the survey responses and evaluate the
improved understanding. The second survey also asked participants, which listed
behaviors they will be adopting or continuing. The listed behaviors are:
o Use a commercial car wash and have car fluid leaks repaired.
o Use fertilizers aid pesticides sparingly, or just use compost.
o Pick up dog waste, bag it and place it in the trash.
o Use natural cleaning products, including detergents that do not contain
phosphorus. For other cleaning needs, avoid products that contain
"Poison"or "Danger"on the label.
Evaluation Conclusions:
From evaluating the su%veys and from volunteer feedback it is clear that the storm
drain marker program is successful in meeting its purpose to inform the target
audience of the problem of stormwater pollution, and to influence behavior that
can contribute to improving water quality in the Puget Sound basin. The program
is successful for the following reasons:
o Ninety-seven pe-cent(97%) of the participants surveyed stated that they
would adopt or continue specific behaviors that help reduce the amount of
pollution carried into streams, lakes, and Puget Sound by stormwater.
•
o Citizen volunteers developed an increased understanding about how the
storm water system functions, and how people's understanding and
behaviors are essential to preventing pollutant materials from entering the
storm drains, and ultimately into stream, river, lake and Puget Sound
waters.
o• Volunteer project managers reported that volunteers had many positive
interactions cont eying the storm drain marker message to residences in
the neighborhoods where they were installing storm drain markers and
distributing educational flyers.
o To date, 1,913 markers have been installed and 4,515 educational flyers
distributed.
Target Audience: General Public-Natural Yard Care Workshops (2010)

pesticides/herbicides and chemical fertilizers, and efficient use of water for
gardens. The 2010 program workshops were designed to teach Renton citizens
King County's designated "best practices"for landscape management through a
sequence of four free, subject-specific workshops offered from mid-September to
early November.
Program measurement: Each of the four Natural Yard Care workshops was
individually evaluated through a pre-and post-workshop survey. The pre-
workshop surveys measured attendees'existing knowledge and practice of
specific natural yard care techniques. Following each workshop, respondents
were asked to consider how often they would practice specific techniques in the
future. Individuals who wished to win free natural yard care prizes were asked to
complete an additional Natural Yard Care Pledge form.
The City of Renton's 2010 Natural Yard Care program was successful for the
following reasons:
o All four workshop presenters addressed King County's Five Steps to
Natural Yard Care through unique content material. This four-workshop
series was designed to teach the public about King County's basic steps to
practice natural yard care. Each of the four presenters covered at least
three of these principles while offering their own expertise and personal
touch to make each workshop unique and interesting.
o Overall workshop attendance was high. In 2009 the City of Renton hosted
one Natural Yard Care workshop that was attended by twenty-five people.
In 2010 a total of sixty-six Renton residents participated in the Natural
Yard Care program, with many participants attending more than one
workshop
Target Audience: General Public-Natural Yard Care Workshops (2011)

The City of Renton's 2011 Natural Yard Care program was successful for the
following reasons:
o All four workshop presenters addressed King County's Five Steps to
Natural Yard Care through unique content,material. This four-workshop
series was designed to teach the public about King County's basic steps to
practice natural yard care. Each of the four presenters covered at least •
three of these principles while offering their own expertise and personal
touch to make each workshop unique and interesting.
o Workshop attendance was high and continues to grow each year. In 2009
the City ofRenton hosted one Natural Yard Care workshop that was
attended by twenty-five people. In 2010 a total of sixty-six Renton
residents participated in the Natural Yard Care program, with many
participants attending more than one workshop. In 2011, attendance
increased by 21(' with eighty individuals attending at least one class of
the four-class series. The majority of these individuals attended more than
one class, with a total attendance of 182.across all four classes.
o Overall, workshop attendees learned new natural yard care principles and
techniques. Survey results showed that 92%of respondents learned new
information about landscape "best practices"and 97%of respondents
committed to practice natural yard care techniques.
The 2012 Natural Yard Care program continued using the principles established
in earlier workshops. As mentioned earlier in this report, the 2012 NYC program
targeted Renton's growing Hispanic population for half of the workshops by
teaching only in Spanish. The two workshops taught in Spanish were well-
received by the participfints. Participant surveys of both the English and
. Spanish-language workshops indicated a strong commitment to reducing reliance •
on using chemicals in their gardens and home landscapes. Over 80% of
participants indicated that the workshops provided them with new information
and new strategies to help them eliminate the use of chemicals and improve the
health of their landscapes.

inventory of the City's storm system. The project includes adding new storm
structures information,lverifying areas lacking structure information, and
mapping newly annexed areas'storm structures. Project work completed through
2012 includes mapping the storm system with data obtained from all existing and
reliable record drawings, updating the GIS storm system schema, verifying areas
lacking structure information, and using Mobile Asset Collection methods to
verify location-of mapped structures and map previously unknown structures.
Continuing project activities includes field verifying the location of known
stormwater system outfalls and where they connect to upstream systems,
identifying and surveying unknown outfalls, and collecting data to fill in missing
attributes for stormwater system assets in the City's GIS.
The City frequently updates and maintains a map of all connections to the
municipal separate stoim sewer, which are authorized or allowed by the City, to
include new facilities or update existing data. This program allows the City to
better isolate and contain IDDE problems and spills. The City storm map is
continually being updated to include new developments and identifying upstream
tributary connections milith missing or inaccurate information. In addition, new
annexations will be included and planned into the City storm mapping, with
updates provided into each annual report, to the extent that the data is available
• from King County.
The City plans on incorporating supplemental information such as drainage'
complaints, billing accounts and spills into the existing stormwater GIS system.
The City's storm system mapping is public information that is available in the
City Hall Development Services help desk area., In additionAlso, beginning in
2012 the City is working on providingimplemented the City's online map viewer

IDD&E Ordinance (S5.C.3.b)
The City will develop and implement an ordinance or other regulatory mechanism
to effectively prohibit non-stormwater, illegal discharges, and/or dumping into the
City's municipal separate storm sewer system to the maximum extent allowable
under State and Federal law.
The City has adopted an ordinance in compliance with all the details listed below.
i. The regulatory mechanism does not need to prohibit the following
categories of non-stormwater discharges:
•
• Diverted stream flows.
• Spring water.
• Rising ground waters.
• Uncontaminated ground water infiltration.
• Uncontaminated pumped ground water.
• Foundation of footing drains.
March 2013 Page 27
City of Renton 2013 Storm Water Management Plan
•
• Water from crawl space pumps.
• Air conditioning condensation.
• Flows from riparian habitats and wetlands.
• Discharges from emergency fire fighting activities.
• Discharges specified in writing by the authorized enforcement agency
as being necessary to protect health and safety.
• Irrigation water from agricultural sources that is commingledwith
urban stormwater runoff.
ii. The regulatory mechanism will prohibit the following categories of non-
stormwater discharges unless the stated conditions are met:
• Discharges from potable water sources, including water line flushing,
hyperchlorinated water line flushing, fire hydrant system flushing, and
pipeline hydrostatic test water. Planned discharges will be de-
chlorinated to a concentration of 0.1 ppm or less,pH-adjusted, if
necessary, and volumetrically and velocity controlled to prevent re-
suspension of sediments in the MS4.
• Discharges from lawn watering and other irrigation runoff. These will
be minimized through, at a minimum,public education activities (see
Section 1) and water conservation efforts.
• Dechlorinated swimming pool discharges. The discharges will be
dechlorinated to a concentration of 0.1 ppm or less,pH-adjusted and
reoxygenized if necessary, volumetrically and velocity controlled to
prevent re-suspension of sediments in the MS4. Swimming pool
cleaning wastewater and filter backwash will not be discharged to the
MS4.
• Street and sidewalk wash water, water used to control dust, and routine
external building wash down that does not use detergents. The City
will reduce these discharges through, at a minimum,public education
activities (see section 1) and/or water conservation efforts. To avoid
washing pollutants into the MS4,the City must minimize the amount.
of street wash and dust control water used. At active,construction sites,
street sweeping must be performed prior to,washing the street.
• Other non-stormwater discharges. The discharges will be in
compliance with the requirements of the stormwater pollution
prevention plan reviewed by the City, which addresses control of •
construction site de-watering discharges.
iii. The City's SWMP will, at a minimum, address each category in ii above
in accordance with the conditions stated therein.
iv. The SWMP will further address any category of discharges in i or ii
above if the discharges are identified as significant sources of pollutants
to waters of the State.
March 2013 Page 28
City of Renton Sto:,rm 2013 Storm Water Management Plan
v. The ordinance or other regulatory mechanism will include escalating
enforcement procedures and actions.
vi. The City will develop an enforcement strategy and implement the
enforcement provisions of the ordinance or other regulatory mechanism.
Following are details about the City's ordinance complying with these permit
requirements:
City Ordinance#5478 prohibits non-stormwater, illegal discharges, and/or
dumping into the City's municipal separate storm sewer system, surface waters,
and ground water. City Ordinance#5478 was authorized on August 3, 2009 to
meet the adoption permit deadline of August 16, 2009. The ordinance includes
adoption of the 2009 Kiilg County Stormwater Pollution Prevention Manual. In
February these discharge prohibition regulations were continued with the
adoption of Ordinance 0526(authorized with an effective date of February 10,
2010). Ordinance#5526 amends the City stormwater code with new surface
water design standards Ifor new development, re-development and construction
sites. These ordinances meet the requirements of NPDES Phase II Permit
Condition S5.C 3.b, including escalating enforcement procedures and actions.
The City implemented its IDDE program prior to August 19, 2011. This section
presents general activities for this on-going IDDE program.
Currently, the City runs a telephone dispatch service through the police
department that allows residents to call in and report a spill that will constitute a
threat to human health, Ithe environment,and welfare anytime. Other storm
drainage problems can be reported via this phone number or other published
phone numbers even after hours. The dispatcher relays the message to the
respective City department and division responsible for response to that call. The
City tracks the call and whether there is a response to any actions necessary, or
whether enforcement is needed. In addition, the City has a published phone
number and email that allows the public to post questions and problems through
the City website. The City periodically evaluates the hotline procedures, and
updates,formalizes, and documents any new protocols established.
Additional IDDE progrgm elements include continuing outreach efforts to
educate the public on IDDE and how public actions affect the downstream
conditions, on-going staff training on IDDE problems and how to identify and
resolve the problems, and summarizing what steps the City is implementing in
each annual report and SWMP document provided to Ecology. The City also has
developed an outfall screening program.
The City currently implements activities and programs associated with IDDE that
complies with the permit. The current compliance activities associated with the
Permit requirements include:
• City currently has an IDDE program.
March 2013 Page 29
City of Kenton 2013 Storm Water Management Plan
• The City has codes and standards that address illicit discharges and civil
infractions.
• Spill Response Standard Operating Procedures Manual.
• Outfall screening program.
• Staff training on IDDE problems and how to ident6 and resolve the ,
problems.
'• The City has an existing storm-water page'on the City's website.
• The City maintains an up-to-date storm map with continual mapping
occurring. The City has a standard operating procedure for keeping the
municipal separate storm sewer system map and inventory up-to-date. The
map is updated with new facilities or corrected for inconsistencies based
on field verification.
• The City has a 24-hour hotline (425-430-7500), through the police
department that allows citizens to call in with surface water complaints
including illicit discharges,flooding, and other surface water related
issues. A tracking mechanism currently receives these calls and routes
them to appropriate City departments. The City plans on reviewing current
and future public education and outreach programs for minimizing-
pollutant discharges, creating IDDE training program, reviewing updated
IDDE.codes to comply with the Permit, tracking and reporting issues that
arise throughout all City departments affecting IDDE.
Ongoing IDD&E Program (S5.C.3.c)
The City will develop and implement an ongoing program to detect and address
non-stormwater discharges, spills, illicit connections and illegal dumping into the
City's municipal separate storm sewer system. The program will be fully
implemented no later than August 19, 2011;and will include:
i. Procedures for locating priority areas likely to have illicit discharges,
including at a minimum: evaluating land uses and associated
business/industrial activities present; areas where complaints have been
registered in the past; and areas with storage of large quantities of materials
that could result in spills.
ii. Field assessment activities, including visual inspection of priority outfalls
identified in i, above, during dry weather and for the purposes of verifying
outfall locations, identifying previously unknown outfalls, and detecting
illicit discharges.
• Receiving waters will be prioritized for visual inspection no later than
three years from February 16, 2009,with field assessments of three
high priority water bodies made no later than February 16,2011. Field
assessments on at least one high priority water body will be made each
year thereafter.
March 2013 Page 30
City of Renton Storm 2013 Storm Water Management Plan
• • Screening for illicit connections will be conducted using: "Illicit
Discharge Detection and Elimination:A Guidance Manual for Program
Development and Technical Assessments", Center for Watershed
Protection, October 2004, or another methodology of comparable
effectiveness.
The City of Renton Surface Water Utility has prioritized City receiving waters for
visual inspection to determine the potential severity of illicit discharge problems
in the municipal separate storm sewer system. The methodology used was based
on a desktop assessment described in Illicit Discharge Detection and Elimination:
A Guidance Manual for'Program Development and Technical Assessments,
Center for Watershed Protection, October 2004.
The Surface Water Utility has conducted outfall assessments of feu&f ve high
priority basins:Black River, Cedar Outfall, North Renton, South Renton, and
Valley basins. The Surface Water Utility will continue outfall assessments for at
least one high priority basin per year.
iii. Procedures for characterizing the nature of, and potential public or
environmental threat posed by, any illicit discharges found by or reported to
the City. Procedures will include detailed instructions for evaluating
whether the disch r! ge must be immediately contained and steps to be taken
for containment of the discharge.
Compliance with this provision will be achieved by investigating(or
referring to the appropriate agency) within 7 days, on average, any
complaints,report's or monitoring information that indicates a potential
illicit discharge, sill, or illegal dumping; and immediately investigating(or
referring)problems and violations determined to be emergencies or
otherwise judged to be urgent or severe.
The City has developed Spill Response Standard Operating manual: This manual
provides City staff with standard operating procedures for responding to spills
within the city that threaten the storm drain system. It includes actions that City
- staff will take to comply with reporting requirements of the Department of

(Condition G3).
iv. Procedures for tracing the source of an illicit discharge; including visual
inspections, and when necessary, opening manholes,using mobile cameras,
collecting and analyzing water samples, and/or other detailed inspection
procedures.
• The City developed a Spill Response Standard Operating Procedures Manual in
2010 (updated August 16, 2011) that includes procedures for tracing the source
of an illicit discharge, and developed a Outfall Assessment Program in 2010
(updated 2011) that includes sampling procedures. Procedures include field

tracking/resolving the system tie-ins, reporting to proper personnel(internally
and externally), coordinating with various permit and resource agencies, and
summarizing actions/results to all stakeholders.
The City has three vactor trucks, two street sweepers, and a CCTV pipeline video
equipped truck that are used for spill response investigation and clean up
operations. The CCTV equipment was funded by an Ecology Municipal
Stormwater Capacity grant.
v. Procedures for removing the source of the discharge; including
notification of appropriate authorities; notification of the property owner;
technical assistance for eliminating the discharge; follow-up inspections;
and escalating enforcement and legal actions if the discharge is not
eliminated.
Compliance with this provision will be achieved by initiating an
investigation within 21 days of a report or discovery of a suspected illicit
connection to determine the source of the connection, the nature and
volume of discharge through the connection, and the party responsible for
the connection. Upon confirmation of the illicit nature of a storm drain
connection, termination of the connection will be verified within 180 days,
using enforcement authority as needed.
City of Renton Ordinance#5478, continued in the adoption of Ordinance
#5526(amending the City stormwater code with new surface water design
standards for new development, re-development and construction sites),
provides escalating enforcement and legal actions if a discharge is not
eliminated.
Public Information (S5.C.3.d)
The City will inform public employees, businesses, and the general public of
hazards associated with illegal discharges and improper disposal of waste.
i. No later than August 19, 2011,the City will distribute appropriate
information to target audiences identified pursuant to Section 1.
ii. No later than February 16, 2009, the City will publicly list and
publicize a hotline or other local telephone number for public reporting
of spills and other illicit discharges. The City will keep a record of calls
received and follow-up actions taken in accordance with Section 3.c.ii.
through v. above; and will include a summary in the annual report(see
section S9 of the City's Permit,Reporting and Record Keeping
Requirements).
Information on illegal discharges and proper disposal are currently provided to
targeted businesses and general public. Information is provided through the City
website: Surface Water Utility web page (Puget Sound Starts Here); Water Utility
web page (water quality and conservation); Storm Drain Marker Volunteer
program;Natural Yard Care workshops;Aquifer Protection program;

events; link to King County Local Hazardous Waste management program; and,
City staff training on IDDE problems and how to identify and resolve the
problems. Additionally; the City produces and distributes flyers to residences and
home owners associations.
The City has evaluated the current hotline procedures, updated the phone
numbers, and documented the protocols. The City web page has been updated to
add the 24-hour hotline information encouraging citizens to report illegal
discharges or illicit dumping to protect water quality. The calls to the hotline are
usually recorded and distributed to the appropriate response authority according
to a spill response matrix.
Program Evaluation and Assessment (S5.C.3.e)
The.City will adopt and{implement procedures for program evaluation and
assessment, including tracking the number and type of spills or illicit discharges
identified; inspections made; and any feedback received from public education
efforts. A summary of this information will be included in the City's annual report
(see section S9 of the City's Permit, Reporting and Recordkeeping.
Requirements).
The City is in compliance. The City tracks identified IDDE incidents. The City is
also implementing an improved asset management database that will log incident
responses with work orders that can access GIS storm water assets.
Training for Municipal Staff(S5.C.3.f)
The City will provide appropriate propriate training for municipal field staff on the
identification and reporting of illicit discharges into MS4s.
i. No later than A gust 16, 2009, the City will ensure that all municipal field
staff who are responsible for identification, investigation, termination,
cleanup, and reporting illicit discharges, including spills, improper
disposal and illicit connections are trained to conduct these activities.
Follow-up training will be provided as needed to address changes in
procedures, techniques or requirements. The City will document and
maintain records of the training provided and the staff trained.
Public Works Maintenance Division staff is trained in identifying,
investigating, and cleaning up illicit discharges. On-going IDDE and BMP
trainings are included in routine Public Works Maintenance staff safety
meetings. This training emphasizes the importance of Best Management
Practices, good housekeeping and spill response.
ii. No later than February 16,2010, an ongoing training program will be
developed and implemented for all municipal field staff, which, as part of
their normal job responsibilities,might come into contact with or
otherwise observe an illicit discharge or illicit connection to the-storm
sewer system will be trained on the identification of an illicit
discharge/connection, and on the proper procedures for reporting and
responding to the illicit discharge/connection. Follow-up training will be
March 2013 L Page 33
City of Kenton 2013 Storm Water Management Plan
provided as needed to address changes in procedures, techniques or
requirements. The City will document and maintain records of the training
provided and the staff trained.
The City has a training program that is assessed and planned during each
employee's yearly performance review. The training review implements an
ongoing employee training to more efficiently affect their abilities out in the
field to assess stormwater maintenance issues which includes the City's IDDE
program.
Across City departments,field employees have received training informing
them about the importance of the NPDES program, and recognizing,
reporting and responding to illicit discharges and connections.
Staff has received training produced by American Public Works Association,
Washington Department of Ecology and Environmental Protection Agencies,
as well as training adapted from Snohomish'County, and other sources for the
City's on-going IDDE training program for field staff.
Additionally,field and in-house staff are certified on erosion and sediment
control techniques that further assists in controlling runoff.
These trainings enable City employees to enhance their knowledge base on
IDDE, controlling runoff, ordinances,.monitoring, etc.

'Section 5: Controlling Runoff from New Development,
Redevelopment and Construction Sites (S5.C.4)
The City will develop, implement, and enforce a program to reduce pollutants in
stormwater runoff to its MS4 fitom new development, redevelopment and construction
site activities. This program will be applied to all sites that disturb,a land area 1 acre or
greater, including projects less ithan one acre that are part of,a larger common plan of the
development or sale. The program will apply to private and public development,
including roads. The"Technical Thresholds"in Appendix 1 of the City's Permit will be
applied to all sites 1 acre or greater, including projects less than one acre that are part of a
larger common plan of the development or sale.
The City will take the following actions and conduct the following activities:
Ordinance (S5.C.4.a)
The program will include an ordinance or other enforceable mechanism that
addresses runoff from new development, redevelopment, and construction site
projects. Pursuant to S5.A.2. of the Permit an ordinance or other regulatory
mechanism will be in place prior to August 16, 2009. Existing City
requirements to apply stormwater controls at smaller sites, or atlower
thresholds than required pursuant to Section 4, will be retained., In addition,
existing City ordinances will remain in place that currently may meet or
exceed the minimum Permit requirements. The ordinance or other
enforceable mechanism will be in place no later than August 16, 2009. The
ordinance or other enforceable mechanism will include, at a minimum:
The City has an active program to reduce pollutants in stormwater runoff
from new developments, redevelopments and construction site'activities. The
existing program applies to both public and private projects.
i. The Minimum Requirements, technical thresholds, and definitions
in Appendix 1 of the City's Permit or an.equivalent approved by '
Ecology under the NPDES Phase I Municipal,Stormwater Permit, •
for new development,redevelopment, and construction sites.
Adjustment and variance criteria equivalent to those in Appendix 1
of the City's Permit will be included. More stringent requirements
'may be used, and/or certain requirements may be tailored to local
circumstances through the use of basin plans or other,similar.water
quality arid quantity planning efforts. Such local requirements will
provide equal protection of receiving waters and equal levels of
pollutant Control to those provided in Appendix 1 of the City's
Permit.
On February 1, 2010,the City of Renton adopted Ordinance No. 5526.
This ordinance amends the City stormwater code with new surface water
design standards for new development, re-development and construction
sites. As written in this ordinance, Renton adopted the 2009 King County
' Surface Water Design Manual, with City Amendments. The amendments
March 2013 Page 3'5
City of kenton 2013 Storm Water Management Plan
to the King County Surface Water Design Manual clarify requirements
that are specific to Renton and are different from the county manual.
The manual ensures that all developments including development less •
than one acre exceeding the thresholds defined in Appendix I of the
Permit comply with all minimum requirements per section S5.C.4.a of the
Phase II NPDES permit.
ii. A site planning process and BMP selection and design criteria that,
when used to implement the minimum requirements in Appendix 1
of the City's Permit(or equivalent approved by Ecology under the
Phase I Permit) will protect water quality, reduce the discharge of
pollutants to the maximum extent practicable and satisfy the State
requirement under Chapter 90.48 RCW to apply all known,
available and reasonable methods of prevention, control and
treatment(AKART)prior to discharge. The City will document how
the criteria and requirements will protect water quality,reduce the
discharge of pollutants to the maximum extent practicable, and
satisfy State AKART requirements.
Ordinance 5526, described above (S5.C.4.a.i), meets this requirement.
iii. The legal authority, through the approval process for new
development, to inspect private stormwater facilities that discharge to the
City's MS4. •
City of Renton Ordinance No. 5526 requires new,private stormwater
facilities to grant permission to the City for inspection purposes. The
updated SWDM requires permit applications to include a Declaration of
Covenant for Maintenance and Inspection of Flow Control BMPs.
Ordinance 5645 amends the City stormwater code to reflect the City's
adopted policy to maintain drainage facilities on single-family residential -
plats with public streets upon completion of the two year maintenance'
and defect bond, and after final construction and inspection by the City.
iv. Provisions to allow non-structural preventive actions and source
reduction approaches such as Low Impact Development Techniques
(LID),measures to minimize the creation of impervious surfaces
and measures to minimize the disturbance of native soils and
vegetation. Provisions for LID_should take into account site
conditions, access and long term maintenance.
The updated SWDM includes LID techniques to minimize creation of
impervious surfaces. The City of Renton requires the implementation of
Low Impact Development alternatives such as dispersion and infiltration
•
for new development and redevelopment projects when feasible to
mitigate for all target surfaces.

v. If the City chooses to allow construction sites to apply the
"Erosivity Waiver"in Appendix 1 of the City's Permit, Minimum
Requirement#2, the ordinance or regulatory mechanism will
include appropriate, escalating enforcement sanctions for
construction sites that provide notice to the City of their intention to
apply the waiver but do not meet the requirements (including
timeframe restrictions, limits on activities that resultin non-
stormwater discharges, and implementation of appropriate BMPs to
prevent violations of water quality standards) to qualify for the
waiver. I '
As written into,the City's updated Surface Water Design Manual,
,waivers are not permitted. The City of Renton requires all projects to
comply with sediment and erosion control(core requirement#5),
including small projects. Appendix D describes sediment and erosion
control measures applicable to all projects not qualifying for small
project drainage review. Projects that trigger small project drainage
review, shall comply with the sediment and erosion control criteria
described in Appendix C(small project drainage review).
Permitting Process (S5.C.4.b)
• The program will include a permitting process with plan review, inspection
and enforcement capability to meet the standards listed in(i)through(iv)
below, for both private and public projects,using qualified personnel (as
defined in Definitions and Acronyms). At a minimum, this program will be
applied to all,sites that disturb a land area one acre or greater, including
projects less than one acre that are part of a larger common plan of the
development or sale. The process will be in place no'later than August 16,
2009.
i. Except as]Iprovided in Section 4.b.vii. below, review of all
stormwater site plans for proposed development activities.
The City has a review process for all of its stormwater site plans for
proposed development activities. The clearing and grading code and the
drainage code address construction site temporary erosion and
sedimentation control. In addition, the construction of permanent storm
flow control and water quality treatment facilities are reviewed by the
City during the permit review process and construction activities.
Monitoring is recorded by City inspectors. The City Surface Water
Utility and Development Services Plan Review Sections provides
drainage review of new developments and redeveloped site plans to
ensure compliance with all sections of the City adopted 2009 King
County Surface Water Design,Manual and City amendments.
ii. Except as1provided in Section 4.b.vii. below, inspect, prior to
clearing and construction, all known development sites that have a
high potential for sediment transport as determined through plan
March 2013 Page 37
City of Renton 2013 Storm Water Management Plan
review based on definitions and requirements in Appendix 7 of the
City's Permit,Identifying Construction Site Sediment Transport
Potential.
Areas where the City knows of high potential for sediment transport have
been determined within the City. New annexed areas will be evaluated
on an on-going project basis with new developments having high
erosivity areas marked. All new developments are brought through the
plan review process which includes a requirement on providing for BMPs
to control erosivity.
iii. Except as provided in Section 4b.vii. below, inspect all known
permitted development sites during construction toverify proper
installation and maintenance of required erosion and sediment
controls. Enforce as necessary based on the inspection.
Inspection of projects is assigned through the assignment of a City
construction inspector for all projects requiring a Public Works
Construction Permit to inspect on-site erosion and sediment control
BMPs.,
iv. Inspect all permitted development sites upon completion of
construction and prior to final'approval or occupancy to ensure
proper installation of permanent stormwater controls such as
stormwater facilities and structural BMPs. Also,verify a
maintenance plan is completed and responsibility for maintenance is
assigned. Enforce as necessary based on the inspection.
The City inspectors conduct a final inspection of all newly constructed
stormwater facilities, redlines any discrepancies between what was
constructed and the plans, and turns the plans over to maintenance
personnel for final redlines prior to final approval or occupancy.
Currently, inspection logs are kept for each project. The existing,
inspection recordkeeping process is being reviewed for potential
overhaul.
v. Compliance with the inspection requirements in ii, iii and iv above
will be determined by the presence and records of an established
inspection program designed to inspect all sites and achieving at
least 95% of scheduled inspections.
vi. An enforcement strategy will be developed and implemented to
respond to issues of non-compliance.
vii. If the City chooses to allow construction sites to apply the
"Erosivity Waiver"in Appendix 1 of the City's Permit, Minimum
Requirement#2, the City is not required to review the construction
stormwater pollution prevention plans as part of the site plan review
in(i) above, and is not-required to perform the construction phase
March 2013 Page 38
City of Renton Storm 2013 Storm Water Management Plan
inspections identified in(ii) and(iii) above related to construction
sites which are eligible for the erosivity waiver.
As written into the updated SWDM, waivers are not permitted, all
development prioject submittals need to include sediment and erosion
control measures.
Long-term Operation and Maintenance (S5.C.4.c)
The program will include provisions to verify adequate long-term operation
and maintenance(O&M) of post-construction stormwater facilities and BMPs
that are permitted and constructedpursuant to (b) above. These provisions will
be in place no later than February 16, 2009 and will include:
i. Adoption of an ordinance or other enforceable mechanism that
dearly identifies the party responsible for maintenance,requires
inspection of facilities in accordance with the requirements in(ii)
through(iv)below, and establishes enforcement procedures.
ii. The City will establish maintenance standards that are as protective
as or more protective of facility function than those specified in
Chapter 4 of Volume V of the 2005 Stormwater Management
Manual for Western Washington. For facilities which do not have
maintenance standards,the City will develop a maintenance
standard.
(1) The iurpose of the maintenance standard is to determine if
maintenance is required. The maintenance standard is not a
measIre of the facilities required condition at all times between
inspections. Exceeding the maintenance standard between the
period of inspections is not a Permit violation.
• (2) Unless there are circumstances beyond the City's control, when
an inspection identifies an exceedance of the maintenance
standard,maintenance will be performed:
Within 1 year for wet pool facilities and retention/detention
. ponds. •
Within 6 months for typical maintenance.
Within 9 months for maintenance requiring re-vegetation.
Within 2 years for maintenance that requires capital
• construction of less than$25,000.
Circumstances beyond the City's control include denial or
delay of access by property owners, denial or delay of
necessary permit approvals, andunexpected reallocations of
maintenance staff to perform emergency work. For each
exceedance of the required timeframe, the City must document
the circumstances and how they were beyond their control.
March 2013 - Page 39

City of Renton 2013 Storm.Water Management Plan
iii. Annual inspections of all stormwater treatment and flow control
facilities,(other than catch basins)permitted by the City according to
Section 4.b. unless there are maintenance records to justify a
different frequency. ,
Reducing the inspection frequency will be based on maintenance
records of double the length of time of the proposed inspection
frequency. In the absence of maintenance records, the City may
substitute written statements to document a specific less frequent
inspection schedule. Written statements will be based on actual
inspection and maintenance experience and will be certified in
accordance with G19 of the City's Permit, Certification and
Signature.
iv. Inspections of all new flow control and water quality treatment
facilities, including catch basins, for new residential developments
that are a part of a larger common plan ofdevelopment or sale,
every 6 months during the period of heaviest house construction
(i.e., 1 to 2 years following subdivision approval) to identify
maintenance needs and enforce compliance with maintenance
• standards as needed.
City of Renton Ordinance No. 5526 identifies the party responsible for
maintenance and requires inspection of facilities. Per the updated
SWDM, applicants will submit a declaration of covenant that identifies
maintenance responsibilities, and right of inspection and maintenance.
City operations and maintenance crews apply BMPs to containing and
minimizing pollutant runofffrom municipal operations. City
responsibilities include inspections of problem areas, inspections of
customer complaints, and maintaining areas via vactoring out the
pollutants from problem areas each year.
The City currently inspects private flow control and treatment facilities
during plat construction. All new constructed facilities will be inspected
as required per the updated Surface Water Design Manual standards.
The standards require the developer to post a two year maintenance and
defect bond. The City has funded a position to address inspections of
• new facilities permitted under the updated Surface Water Design Manual.
On October 18, 2010, Council approved a new program to assume
maintenance and operation of all stormwater facilities in plats that
manage runofffrom public streets. Ordinance 5645 amends the City
stormwater code to reflect the City adopted policy to maintain drainage
facilities on single-family residential plats with public streets upon
completion of the two-pear maintenance and defect bond, and after final
construction and inspection by the City. The budget needed to implement
the program was approved as part of the 2012 budget adjustment process
and will be phased in over a few years.

The Surface Water Utility has been inspecting the facilities and working
with the Homeowners Associations (HOAs) to bring them up to City
maintenance standards so that the facilities could be transferred to the
City to assume maintenance starting in 2012. There are a sufficient
number offacilities that have been properlymaintained by the HOAs te-
warrantthat the City began implementing half of the program in 2012,_.
including hiring maintenance staff and purchasing equipment. The City
also began working with facility owners to transfer maintenance
responsibility to the City. As part of this process the City began routine
maintenance on twenty-four of these facilities through access and
maintenance agreements that are in effect until the formal transfer
documents are executed. The remaining half of the program would will
be,implemented in 2014.
The City is also developing improvements to its GIS database, is •
implementing a new assets management database, and is implementing a
new permits management database.
•
Municipal operation and maintenance activities related to utility . •
installations, street cleaning, ditch maintenance and other City activities
include, but aH not limited to public streets, receiving public/private
parcels, and parking.
The Surface Water Utility Maintenance Section currently has 12 15
FTEs, three vactor trucks, a CCTV pipeline video equipped truck and
other equipmenit used to maintain and operate publicly owned •
stormwater management systems and facilities.
Record Keeping (S5:C.4.d)
The program will include a procedure for keeping records of inspections and
enforcement actions by staff, including inspection reports, warning letters,
notices of violations and other enforcement records. Records of maintenance
inspections and maintenance activities will be maintained. The City will.keep
records of all projects disturbing more than one acre, and all projects of any
size that are part of a common plan of development or sale that is greater than
one acre that are approved after February 16, 2007.
The City maintains a record keeping system that includes permitting,
enforcements, and construction inspections on private and public facilities
construction projects. This is done through the City's,code compliance
process.
Currently, the City crews utilize a Maintenance Management System (MMS)
that records time and resources spent on all cleaned pipelines, catch basins,
ditches, replaced storm pipelines, cleaned vaults, and cleaned ponds related
to the City's O&M activities. In addition, the City records areas cleaned and
inspected on a yearly basis via paper maps.

Additionally, the City is developing improvements to its GIS database, is
implementing a new assets management database, and is investigating
acquisition of a new permits management database. In 2009, the City
initiated a $680,000 Storm System Mapping project to improve the mapping
and inventory of the City's storm system. This protect includes filling in
necessary field naappinginformation of unknown system areas. The mapping
project is scheduled to continue through 2013. In 2010,the City began
implemented implementing a new MMS system (Enterprise Access
Maintenance) that integrates with the GIS for future operations activities. In
2012, the City began implementing a new permits management database
(EnerGov). In 2009, thc City initiated a $680,000 Storm System Mapping
project to improve thc mapping and inventory of-the City's storm system. This
project includes filling in necessary field mapping information of unknown
system 'areas. The mapping project is scheduled to continue through 2010.
The City uses/a MS Access database linked to GIS stormwater system'data to
• maintain records of privately owned and maintained stormwaterflow control
and water quality facility inspections, maintenance correction notifications,_
•
and maintenance compliance.
Availability of NOls (S5.C.4.e)
The City will make.available copies of the "Notice of Intent for Construction
Activity" and copies of the "Notice of Intent for'Industrial Activity" to
representatives of proposed new development and redevelopment. The City
• will continue to enforce local ordinances controlling runoff from sites,that are
also covered by stormwater permits issued by Ecology.
NOI forms and information are currently provided within the City's
Department of Community &Economic Development(Development Services
Division.) Currently, Development Services directs proposed new and
redevelopment projects to obtain these NOIs.
Development Services will now also provide information and NOI forms from
the new Surface Water Design Manual to applicants at pre-application
meetings to make them aware of this requirement if it is obvious that the
project will be disturbing more than one acre of land or more.
Training (S5.C.4.f)
No later than August 16, 2009, the City will verify that all staff responsible for
implementing the program to control stormwater runoff from new
development, redevelopment, and construction sites, including permitting,
plan review, construction site inspections, and enforcement, are trained to
conduct these activities. Follow-up training will be provided as,needed to
address changes in procedures, techniques or staffing. The City will document
and maintain records of the training provided and the staff trained.

Section 6: Pollution Prevention and Operation and
Maintenance for Municipal Operations (S5.C.5)
By February 16, 2010, the City will develop and implement an operations and
maintenance (O&M)program that includes a training component and has the ultimate
goal of preventing or reducing pollutant runoff from municipal operations.
The City will take the following actions and conduct the following activities:
Maintenance Standards (S5.C.5.a)
The City will establish maintenance standards that are as protective as or more
protective, of facility function than those specified in Chapter 4 of Volume V
of the 2005 Stormwater Management Manual for Western Washington. For
facilities which do not have maintenance standards, the City will develop a
maintenance standard.
i. The purpose of the maintenance standard is to determine if
maintenance is required. The maintenance standard is not a measure
of the facilities required condition at all times between inspections.
Exceeding the maintenance standard between inspections and/or
maintenance is not a Permit violation.
ii. Unless there are circumstances beyond the City's control, when an
inspection identifies an exceedance of the maintenance standard,
maintenance will be performed:
Within 1 year for wet pool facilities and retention/detention ponds.
Within 6 months for typical maintenance.
Within 9 months for maintenance requiring re-vegetation.
Within 2 years for maintenance that requires capital construction
of less than$25,000.
Circumstances beyond the City's control include denial or delay of access by
property owners, denial or delay of necessary permit approvals, and
unexpected reallocations of maintenance staff to perform emergency work.
For each exceedance of the required timeframe;the City will document the
circumstances and how they were beyond their control.
Maintenance standard guidelines are established to comply with the permit
requirements within three years of the effective date of the Permit(February 16,
2010). These maintenance standards contain the following: •
1. Training for maintenance staff emphasizes IDDE, and sediment and
erosion control practices.
2. Maintenance standards for inspecting facilities. Effective February 10,
2010, the City adopted the 2009 King County Surface Water Design
Manual, including Appendix A -Maintenance Standards. The City also
adopted by reference the 2009 King County Stormwater Pollution
Prevention Manual. The City currently follows an Integrated Pest

Management policy for City-owned facilities that contains guidance and
standard operating procedures for applying fertilizer and/or pest
spraying, and storing chemicals, and sediment/erosion control. The City
Parks Departm;nt is a certified Audubon Cooperative Sanctuary.
3. All known municipally owned or operated treatment and flow control
facilities are inspected and maintained at a minimum, annually.
4. Total inspection of all catch basins and inlets owned by the City at least
once prior to the end of the Permit term with cleaning conducted on them
if they are deemed out of compliance with the maintenance standards.
5. Erosion and sediment control of City projects and facilities are followed
according to SWPPPs developed for each project that are greater than
one acre in size and smaller projects, if drainage review is required, that
includes the erosion control plans,practices, and procedures. In
addition, general erosion and sediment control practices are followed
according to thi City's Operations Manager, who is a CESCL.
General Inspections (S5.C.5.b)

taking appropriate maintenance actions in accordance with the adopted
•
maintenance standards. The annual inspection requirement may be reduced
based on inspectionjrecords.
Reducing the inspection frequency will be based on maintenance records of
double the length of time of the proposed inspection frequency. In the absence
of maintenance records, the City may substitute written statements to
document a specifics less frequent inspection schedule. Written statements will
be based on actual inspection and maintenance experience and will be
certified in accordance with G19 of the City's Permit, Certification and
Signature.
Maintenance staff inspectsand maintains public owned treatment and flow
control facilities per adopted King County Storm Water Design Manual,
Appendix A. Facilities are inspected annually. Inspections are done more
frequently at historical problem areas within the City. Maintenance is
performed as needed per inspection results.
Post-Storm Inspections(S5.C.5.c)
•
Spot checks of potentially damaged permanent treatment and flow control
facilities (other than catch basins) after major(greater than 24-hour-10-year
recurrence interval rainfall) storm events. If spot checks indicate widespread
damage/maintenance needs, inspect all stormwater treatment and flow control
facilities that may be affected. Conduct repairs or take appropriate
maintenance action in accordance with maintenance standards established
above,based on the;results of the inspections.

Major post-storm checks are currently a work item of City personnel.
Facilities that typically require post storm maintenance are inspected and
receive sediment cleaning as needed following major storms.
Catch Basins and Inlet Inspections (S5.C.5.d)
Inspection of all catch basins and inlets owned or operated by the City at least
once before the end of the City's Permit term. Clean catch basins if the
inspection indicates cleaning is needed to comply with maintenance standards
established in the 2005 StormWater Management Manual for Western
Washington. Decant water will be disposed of in accordance with Appendix 6
of the City's Permit, Street Waste Disposal.
Inspections may be conducted on a"circuit basis"whereby a sampling of
catch basins and inlets within each circuit is inspected to identify maintenance
needs. Include in the sampling an inspection of the catch basin immediately
upstream of any system outfall. Clean all catch basins within a given circuit at
one time if the inspection sampling indicates cleaning is needed to comply
with maintenance standards established,under Section 4.c., above.
As an alternative to inspecting catch basins on a"circuit basis,"the City may
inspect all catch basins, and clean only catch basins where cleaning is needed
to comply with maintenance standards.
The City has increased inspection frequency to comply with the Permit
requirements and to establish a circuit basis for the inspections. When
required, maintenance.typically includes pipe cleaning, culvert cleaning, ditch
maintenance, street cleaning, road/pipe repairs, and maintaining roadside
areas including vegetation management.
Compliance (S5.C.5.e)
Compliance with the inspection requirements in a,b, c and•d above will be
determined by the presence of an established.inspection program designed to
L.
inspect all sites and achieving inspection of 95% of all sites.
These compliance criteria are part of the maintenance and inspection
standards established by the City prior to August 16, 2010. ,
Reduction of Stormwater Impacts (S5.C.5.f)
Establishment and implementation of practices to reduce stormwater impacts, •
associated with runoff from streets,parking lots,roads or highways owned or
maintained by the City, and road maintenance activities conducted by the
City. The following activities will be,addressed:
• Pipe cleaning •
• Cleaning'of culverts that convey stormwater in ditch systems
• Ditch maintenance
• Street cleaning
• Road repair and resurfacing, including pavement grinding
March 2013 , Page 46
City of Renton Storm 2013 Storm Water Management Plan
• Snow and ice control
• Utility installation
• Pavement striping maintenance
•. • Maintaining roadside areas, including vegetation management
• Dust control
The City currently has an Operations and Maintenance Department that
conducts all of these activities.
Policies and Procedures (S5.C.5.g)
Establishment and implementation of policies and procedures to reduce
pollutants in discharges from all lands owned or maintained by the City and
subject to the City's Permit, including but not limited to: parks, open space,
road right-of-way, maintenance yards, and stormwater treatment and flow
control facilities. These policies and procedures will address, but are not
limited to:
• Application of fertilizer,pesticides, and herbicides including
the development of nutrient management and integrated pest
management plans.
• Sediment and erosion control.
• Landscape maintenance and vegetation disposal.
• Trasli management.
• Building exterior cleaning and maintenance.
The City currently possesses and follows a documented Integrated Pest
Management policy that is applied to parks and open spaces. In addition,
erosion control is applied upon projects to control sediment-laden runoff on
City projects as well as private development projects. The City Parks
Department is a certified Audubon Cooperative Sanctuary.
Training for mainten1 ance staff emphasizes IDDE, and sediment and erosion
control practices. Maintenance staff are state licensed applicators. -
The City's Public Works Maintenance Division has committed to the Regional
ESA Road Maintenance BMP Guidelines.
City projects and drainage facility maintenance are regulated by the City's
adopted Surface Water Design Manual.
The City adopted by reference the 2009 King County Stormwater Pollution
Prevention Manual.'[City of Renton Ordinance No. 5478, August 3, 2009 &
Ordinance No. 5526, February 10, 2010].
' 1 .
Training (S5.C.5.h)
Develop and implement an on-going training program,for employees of the
City whose construction, operations or maintenance job functions may impact
stormwater quality. The training program will address the importance of
protecting water quality, the requirements of the City's Permit, operation and
maintenance standards, inspection procedures, selecting appropriate BMPs,
March 2013 • Page 47
City of Renton 2013 Storm Water Management Plan
•
ways to perform their job activities to prevent or minimize impacts to water
quality, and procedures for reporting water quality concerns, including
potential illicit discharges. Follow-up training will be provided as needed to •
address changes in procedures, techniques or requirements. The City will
document and maintain recordsof training provided.
The City has maintenance crews who attend training programs emphasizing
erosion control, maintenance recording, documenting, spill prevention,
recognizing and reporting illicit discharge detections, and inspections.
Additionally, the Maintenance Department attends the County Road
• Standards and Compliance meetings in order to apply the latest in developing
of set maintenance standards. Future training programs will be recorded by
the Maintenance Manager.
Existing training staff programs will be reviewed periodically to determine if .
they need to be modified or if new training is necessary to maintain
compliance with the permit requirements.
Special Facility Requirements.(S5.C.5.i)
Development and implementation of a Stormwater Pollution Prevention Plan
(SWPPP) for all heavy equipment maintenance or storage yards, and material
storage facilities owned or operated by the City in areas subject to the City's
Permit that are not required to have coverage under the Industrial Stormwater
General Permit. Implementation of non-structural BMPs will begin
immediately after the pollution prevention plan is developed. A schedule for
implementation of structural BMPs-will be included in the SWPPP. Generic
SWPPPs that can be applied at multiple sites may be used to comply with this
requirement. The SWPPP will include periodic visual observation of
discharges from the facility to evaluate the effectiveness of the BMP.
The City developed a Stormwater Pollution Prevention Plan (SWPPP)for its
Public Works Maintenance and shops facility. [Implementation date:
February 1, 2010] The Public Works Maintenance and shops facility
accommodates a variety of Public Works buildings and activities, including
vehicle maintenance activities. The site also accommodates storage of Parks
Department equipment and materials, the Police vehicle impound building
and the Animal Control dog kennel.
City staff evaluated and determined that the City-owned Municipal Airport
requires an Industrial Facility NPDES Permit. 4 SWPPP for the airport
would likely be required under that permit. The City will be planning budget
for and development of an Industrial Facility NPDES Permit application
during 2010.
March 2013 Page 48

Record Keeping (S51.C.5.j)
Records of inspections arid maintenance or repair activities conducted by the
City will be maintained in accordance with S9 of the City's Permit, Reporting
Requirements.
Currently, the City crews utilize a Maintenance Management System (MMS)
that records time and resources spent on all cleaned pipelines, catch basins,
ditches, replaced storm pipelines, cleaned vaults, and cleaned ponds related
to the City's O&M activities. In addition, the City records areas cleaned and
inspected on a yearly basis via paper maps.
Some records of inspectionsand maintenance or repair activities are
currently kept in project file folders that are kept in storage files along with
the project contents. In the future, inspections/maintenance and repair
activities are to be provided in one storage area that can be easily accessible
per S9 of the Permit{
The City is developing improvements to its GIS database, and is implementing
a new assets management database. In 2010, the City is implemented a new
MMS system (Enterprise Access Maintenance) that integrates with the GIS for
future operations activities. In 2009, the City initiated a $680,000 Storm
System Mapping project to improve the mapping and inventory of the City's
storm system. This project includes filling in necessary field mapping
information of unknown system areas. The mapping project is schedule to
continue through 2010. .
Section 8: Monitori g
A. Permittees are not required to conduct water sampling or other testing during the
effective term of this Permit, with the following exceptions:
1. Any water quality monitoring required for compliance with TMDLs,pursuant to
section S7 Compliance with Total Maximum Daily Load Requirements and
Appendix 2 of this Permit, and
2. Any sampling or testing required for characterizing illicit discharges pursuant to
section S5.C.3. or S6.D.3. of this Permit.
There is no approved Total Maximum Daily Load(TMDL) applicable to stormwater
discharges from the City's owned and operated storm system.
B. The Permittee shall provide the following information in each annual report:
1. A description of any stormwater monitoring or studies conducted by the Permittee
during the reporting period. If stormwater monitoring was conducted on behalf of
the Permittee, or if studies or investigations conducted by other entities were
reported to the Permittee, a brief description of the type of information gathered or
received shall be included in the annual report(s) covering the time period(s)the
information was received.
March 2013
Page 49
City of Renton 2013 Storm Water Manageindnt Plan
No stormwater monitoring was conducted during this permit period.
2. An assessment of the appropriateness of the BMPs identified by the Permittee for
each component of the SWMP; and any changes made, or anticipated to be made,
to the BMPs that were previously selected to implement the SWMP, and why.
The BMPs are appropriate because the permit requires them.
3. Information required pursuant to S8.C.2. below.
C. Preparation for future, long-term monitoring
This section does not apply to secondary permittees. However, secondary permittees
are required to provide information, maps and access for sampling efforts, as
necessary. Secondary permittees are encouraged to participate in the monitoring
program.
1. All cities, towns and counties shall prepare to participate in the implementation of
a comprehensive long-term monitoring program. The monitoring program will
include two components: stormwater monitoring and targeted Stormwater
Management Program (SWMP) effectiveness monitoring. Stormwater monitoring
is intended to characterize stormwater runoff quantity and quality at a limited
number of locations in a manner that allows analysis of loadings and changes in
conditions over time and generalization across the permittees'jurisdictions.
Stormwater program effectiveness monitoring is intended to improve stormwater
management efforts by evaluating issues that significantly affect the success of, or
confidence in, stormwater controls. The monitoring program can include long-
term monitoring and short-term studies. The results of the monitoring program
will be used to support the adaptive management process and lead to refinements
of the SWMP.
The City contracted with Herrera Environmental Consultants to develop a monitoring
plan. The plan summarizes site selection and the basic monitoring design for two
components of the long-term monitoring program specified in the National Pollutant
Discharge Elimination System (NPDES) Western Washington Phase II Municipal
. Stormwater permit(Ecology 2009a): Stormwater monitoring(S8.C.1.a) and
Stormwater Management Program Effectiveness (SWMP) monitoring(S8.C.1.b). The
monitoring plan follows guidance provided in the Washington State Department of
Ecology (Ecology)Monitoring and Reporting Guidance—Phase II Municipal
Stormwater Permits (Ecology 2010). The plan is organized into two main sections
including information related to the stormwater monitoring sites and SWMP
monitoring sites, respectively.
•
a. Stormwater monitoring
Cities having a population greater than 10,000 and counties having a population
greater than 25,000 shall identify sites for long-term stormwater monitoring.
Adequate sites will be those completely mapped as required in S5.C`3.a. and be
suitable for permanent installation and operation of flow-weighted composite
sampling equipment. No later than December 31, 2010:
March 2013 Page 50
City of Renton Storm 2013 Storm Water Management Plan
i. Each county having a population greater than 100,000 shall identify three
outfalls or conveyances where stormwater sampling could be conducted.
One outfall or conveyance shall represent commercial land use, the second
shall represent low-density residential land use and the third will represent
medium-to-high density residential land use.
ii. Each city having a population greater than 75,000 shall identify three
outfalls or.coriveyinces where stormwater sampling'could be conducted.
One outfall or conveyance shall represent commercial land use, the second
shall represent high-density residential land use and the third will represent
industrial land use.
In 2010, City population is approximately 83,500. The City's monitoring plan
includes a proposed monitoring site for one conveyance representing primarily
commercial land use, la second proposed monitoring site representing primarily
high-density residential land use and a third proposed monitoring site
representing primarily industrial land use.
iii. Each county having a population between 25,000 and 100,000 shall identify
two outfalls or conveyances where stormwater sampling could be
conducted. One outfall shall represent commercial land use and the second
one will represent low-density residential land use.
iv. Each city having a population between 10,000 and 75,000 shall identify two
outfalls or conveyances where stormwater sampling could be conducted.
One outfall shall represent commercial land use and the second will
represent high-density residential land use.
v. Permittees shall s alect outfalls or conveyances based on known water
quality problems and/or targeted areas of interest for future monitoring. The
Permittee shall doeument:
• Why sites were selected; .
• Possible site constraints for installation of and access to monitoring
equipment;
• A brief description of the contributing drainage basin including size in
acreage, dominant land use, and other contributing land uses;
• Any water quality concerns in the receiving water of each selected outfall
or conveyance. '1
The SWU conducted a desktop screening assessment to prioritize receiving
waters based on the following criteria. Using information from this preliminary
screening and evaluation of receiving water concerns, the SWU identified a
number of candidate sites in the stormwater conveyance systems draining to
these receiving waters based on their representativeness for monitoring runoff
from the land use categories identified in the Phase II Municipal Stormwater
permit.
The SWU also conducted field visits to determine the feasibility of monitoring at
these candidate sites given site-specific characteristics related to monitoring
logistics such as the hydraulics in the conveyance system and access.
March 2013 Page 51
J •
City of he Ston 2013 Storm Water Manag nt Plan
Information obtained from these field visits,helped to narrow down the list of
monitoring sites to three monitoring sites selected for long-term monitoring.
The City's monitoring plan identifies possible constraints for installation of and
access to monitoring equipment. It also, includes a description of the
contributing drainage basin and known water quality concerns in-the receiving
water of each selected conveyance.
b. SWMP effectiveness monitoring
i. Each city, town and county shall prepare to conduct monitoring to determine
the effectiveness of the Permittee's.SWMP at controlling stormwater-related
problems that are directly addressed by actions in the SWMP. This
component of the monitoring program shall be designed to answer the
following types of questions:
• How effective is a targeted action or narrow suite of actions?
• Is the SWMP achieving a targeted environmental outcome?
iii. No later than December 31, 2010, each city, town and county shall
identify at least two suitable questions'and select sites where monitoring
will be conducted. This monitoring shall include, at a minimum,plans
for stormwater, sediment or receiving water monitoring of physical,
chemical and/or biological characteristics. This monitoring may also
include data collection and analysis of other measures of program
effectiveness,problem identification and characterizing discharges for •
planning purposes.
Two aspects of the stormwater program the City's monitoring plan will focus on
include the effectiveness of the new construction sediment and erosion control
inspection program and addressing high fecal coliform bacteria concentrations
in Johns Creek The following two questions were prepared to address each of
these issues:
1. How effective are the new construction inspection programs in reducing
turbidity levels from construction sites?
2. How effective is a targeted public education program for pet waste in
reducing fecal coliform,bacteria concentrations in Johns Creek?
iii. For each question, the Permittee shall develop a(monitoring plan containing
the following elements:
• A statement of the question, an explanation of how and why the issue is
significant to the Permittee, and a discussion of whether and how the
results of the monitoring may be significant to other MS4s.
• A specific hypothesis about the issue or management actions that will be
tested.
• • Specific parameters or attributes to be measured.
March 2013 Page 52
City of Renton Storm 2013 Storm Water Management Plan
• Expected modifications to management actions depending on the outcome
of hypothesis testing.
The City's monitoring plan addresses each of the above requirements.
2. Monitoring program reporting requirements
a. The fourth annual report shall:
i. Describe the status of identification of sites for stormwater monitoring, if
required for the Permittee.
ii. Include a summary of proposed questions for the SWMP effectiveness
monitoring and describe the status of developing the monitoring plan,
including the proposed purpose, design, and methods.
The City's monitoring plan was included in the fourth annual report.
b. To comply with the requirements of all or part(s) of this section,permittees in a
single Urbanized Area or WRIA may choose to submit a collaborative report or
reports in lieu of separate reports.
The City Surface Water Utility has also evaluated the cost of implementing a local
monitoring program compared to the pay-in option for the Regional Monitoring
Plan (based on the City's population). The evaluation summarizes the costs,
benefits, and limitations of a local monitoring program based on the Monitoring
and Reporting Guidance-Phase II Municipal Stormwater Permits' (Ecology
2010) versus the pay-in option for the regionally coordinated monitoring
programs to be implemented as part of the Stormwater Monitoring and Assessment
Strategy for the Puget Sound Region (Ecology 2011). The costs of the Regional
Stormwater Monitoring Program (RSMP) are based on the `Western Washington
Phase II Municipal Stormwater General Permit Preliminary Draft Language'
released for public review and comment by the Washington State Department of
Ecology on May 16, 2011 (Ecology 2011).
Costs Compared
The cost estimate•of the local stormwater monitoring program for a five-year
permit term,is$362,891 $513,371. The RSMP cost(pay-in option)for the City
over the five-year permit term $288,247—$311,976. Note:Based on Ecology's
draft Permit for the 2013-2018 permit cycle, these costs may need to be updated
because the final 2013-2018 permit may have different requirements and different
RSMP costs then Ecology had proposed when this monitoring cost evaluation was
conducted.
Benefits of Local Monitoring
The benefits of implementing a local monitoring program are as follows:
■ The City can monitor stormwater drainage systems of interest within the City
limits to determine impacts of SWMP changes on its water bodies.
March 2013 Page 53
City of Renton 2013 Storm Water Manage dent Plan
• The City can address specific SWMP effectiveness questions of interest within
the City limits.
■ The data collected would be specific to water quality in Renton and can be
used to educate the public, and when making program,project, and policy
decisions.
Limitations of Local Monitoring
The limitations of implementing a local monitoring program are as follows:
■ Staff knowledge and availability (if sampling is-conducted in-house).
Additional staff hires or consultants help would likely be needed to implement
the program.
• Initial monitoring year is expensive with capital costs for equipment
purchases.
■ Replacement of equipment if stolen or vandalized can be expensive and may
not always be factored into the monitoring budget for any given year.
Benefits of opting in to the RSMP
The benefits of opting in to the regional monitoring program are as follows:
■ The City does not have to use limited staff time and availability on stormwater
monitoring since it will most likely be contracted out to a third party.
■ The City does not have to contend with the high capital costs in the initial
year of monitoring since the costs will be spread out evenly over the permit
term. -
■ The City does not have to contend with the costs of replacing equipment that
is stolen or vandalized.
■ Less expensive than if the City implemented its own monitoring program.
Limitations of the RSMP
The limitations of opting in to the regional monitoring program are as follows:
■ Monitoring most likely will not be focused on the water bodies and issues
within the City limits.
■ Monitoring may not address the specific SWMP effectiveness monitoring
questions that the City would like to have answered since the effectiveness
monitoring questions will be selected at a regional and not a local scale.
■ The ambient monitoring described in the RSMP far oversteps what the
Environmental Protection Agency (EPA) outlined for Phase II permittees.
The EPA recommends a limited monitoring of a few pollutants of concern. •
The RSMP is recommending a comprehensive monitoring, which would tie-up
the resources Permittees would otherwise use to improve water quality, while
gathering no substantive new information.
■ The Washington.Pollution Control Hearings Board(PCHB) is cited as
endorsing the requirements in S8. But the requirements are not in accordance
with PCHB recommendations. PCHB recommended that a regional
March 2013 Page 54
•
City of Ren o i Storm 2013 Storm Water Management Plan
consortium be established to frame a regional monitoring program, but did
not endorse its outcome. The RSMP outcomes would not be in accordance
with PCHB recommendations, since: the program is not limited; it does not
reduce the economic burden on jurisdictions; the data set would not be
generated for several permit cycles (a minimum of ten years); and it would
not provide jurisdictions the ongoing feedback allowing them to improve their
programs.
■ The comprehensive monitoring required by RSMP is redundant. The common
sources of urban stormwater pollutants are well-known and documented by a
host of other studies and data sources (conducted by Ecology, National
Oceanic and Atmospheric Administration, WA Department of Health, and
National Stormwater Quality Database). Rather than spending time and
money to assess whether the Western WA Phase I and Phase II Permittees
have similar trends in their receiving waters, resources should be directed to
known methods of reducing these pollutants (retrofits, maintenance,
education, etc).
• The RSMP monitoring is not useful to municipalities for Ecology's intended
purpose of feedbackfor assessing and improving municipalities'pollutant
reduction programs and this data will not be available for several permit
cycles. Even after the data is collected, it would still not provide clear
direction for municipalities. (Urban Stormwater Management in the United
States, National Research Council, 2008, states that it is not yet possible to
create a protocol that mechanistically links stormwater dischargers to the
quality of receiving waters.)
• The RSMP has open-ended parameters that would allow it to expand still
more in scope, again without taking into account the burden on Permittees to
implement these requirements. (Additional sample parameters, Table 4, 2012
Status and Trends Stormwater Monitoring and Assessment Strategy for Small
Streams, QAPP)
■ The management and oversight of the RSMP is not formally established and is
untested. Ecology is proposing to implement this massive regional
stormwater monitoring program all at once with very little clarity about how
and who will manage and administer this program. Once the program is
established in the permit, the cost will likely increase in subsequent future
permit updates and jurisdictions would have nooption but to pay into the ,
RSMP or be in violation of the NPDES permit.
•
Record Keeping (S9.E.4) •
4. Permittees shall include with the annual report submitted no later than March 31,
2011,information that at'a minimum includes:
a. A summary of identified bathers to the use of low impact development(LID)
within the area covered by the permit and measures to address the barriers. Each
individual Permittee must complete this summary.
March 2013 Page 55
•
City of Renton 2013 Storm Water Manage-_-nt Plan.
b. A report completed by an individual Permittee or in cooperation with multiple
Permittees describing, at a minimum:
i. LID practices that are currently available and that can reasonably be
implemented within this permit term.
ii. Potential or planned non-structural actions and LID techniques to prevent
stormwater impacts.
iii. Goals and metrics to identify,promote, and measure LID use.
iv. Potential or planned schedules for the Permittee(s) to require and implement
the non structural and LID techniques on a broader scale in the future.
The City Surface Water Utility prepared a report that identifies barriers to implementing
LID approaches in the City of Renton. Barriers were identified through a literatui-e
review and internal discussions with City Departments.

City of Renton Storm 2010 Storm Water Management Plan
Introduction
This document has been prepared to meet the City of Renton's Western Washington
Phase II Municipal Stormwater Permit(Permit)requirement for development of a
Stormwater Management Program (SWMP).
The City's SWMP is designed to develop numerous actions and activities to reduce the
discharge of pollutants from the City's Municipal Separate Storm Sewer System(MS4)
to the maximum extent practicable (MEP)to meet Washington State's All Known and
Reasonable Treatment (AKART)requirements, and protect water quality. This goal is
accomplished by the inclusion of all Permit SWMP components, minimum measures and
implementation schedules into the City's SWMP.
Where the City is already implementing actions or activities called for in the SWMP,the
City will continue those actions or activities regardless of the schedule called for in this
document.
As part of the implementation of the City's SWMP,the City will gather,track, maintain
and use information on an on-going basis to evaluate the SWMP development,
implementation, Permit compliance, and to set priorities. Beginning no later than
January 1, 2009, the City will begin to track the cost(or estimated cost) of development
and implementation of each component of the SWMP.
This document will be evaluated and updated at least annually for submittal with the
City's Annual Report to the Department of Ecology by March 31 each year as required
per the Permit. The following document sections are arranged per the Permit
requirements as outlined in section S5.C. This SWMP includes a description of each
City program component per S5.0 and additional actions implemented by the City as an
extra to the Permit or as a response to compliance with Total Maximum Daily Load
Requirements (TMDLs).

The following SWMP is formatted with permit requirements in regular text type and
italic text is how the City is addressing the permit requirements.
Section 1 : Development; Implementation and Permit
Compliance (S5.A.3)
The SWMP shall include an ongoing program for gathering,tracking,maintaining, and
using information to evaluate SWMP development, implementation and permit
compliance and to set priorities. -
a) Beginning no later than January 1, 2009, each Permittee shall track the cost or
estimated cost of development and implementation of each component of the
SWMP. This information shall be provided to Ecology upon request.
Using its existing accounting system, the City started an Estimated Cost Tracking •
program with the purpose of obtaining an approximated cost of developing and
implementing a SWMP by program components. The program components as
defined by the permit are: Public Education, Public Involvement, IDDE, Control of
Runoff from Development (Review and Inspection), and Operations and
Maintenance. Under each component, types of activities that the City is likely to
engage in over the current permit cycle were identified Monitoring and General
Permit Management are possible future components to be included.
The City tracks Permit related costs by approximating the expenditures spent from
each City department by extracting out the percentage of NPDES program funds
spent. Essentially, the cont tracking method derives an estimate for each department
division by multiplying the division's annual operating expenditures by the-
percentage of division stag spent of NPDES activities. This method captures the
cost of salary and benefits as well as relative support costs, i.e.facilities, technical
services, and administration supplies. Added to this estimate are CIP costs, i.e.
professional service contracts for storm system inventory mapping and development
of surface water design standards.
b) Each permittee shall track the number of inspections, official enforcement actions
and types of public education activities as stipulated by the respective program
component. This information shall be included in the annual report.
The City currently has a program for record keeping. This program
highlights specific record's and categorizes the records into three categories as
explained.below. I
• Category 1 records mainly fall into four components:
o Public Education
o IDDE
o Development Review and Inspection
o Operations &Maintenance

• Categories 2 and 3 would be more informal records kept, maintained and
updated by active members of the SWMP program.
• Spill Response Records: Spills are tracked and kept at the City. These spills
are types that may pose an environmental or health hazard

Section 2: Public Education and Outreach -(S5.C.1)
The City's SWMP includes an education program aimed at residents,businesses,
industries, elected officials,policy makers,planning staff and other employees of the
City. The goal of the education program will be to reduce or eliminate behaviors and
practices that cause or contribute to adverse stormwater impacts. The City's education
program may be developed locally or regionally.
Permit Requirements
The Phase II Permit(Section Section S5.C1) requires the City's SWMP to include an
education and outreach program covering specified subjects and audiences. Section
S5.Cl.a-c lists the following Jequirements:
• Prioritize and address the target audiences and subject areas listed in the Permit
based on stormwater issues.
• Develop education and outreach programs that are designed to reduce or eliminate
behaviors and practices that cause or contribute to adverse stormwater impacts.
• Measure changes in the understanding and adoption of behaviors by the target
audience, and use that information to evaluate past programs, and to direct future
programs.
• Maintain records of public education and outreach activities
Public Education and Outreach Program (S5.C.1.a)
No later than Febru16, 2009, the City will provide an education and outreach
program for the area served by its Municipal Separate Storm Sewer System
(MS4). The outreach i rogram will be designed to achieve measurable
improvements in the target audience'sunderstanding of the problem and what
they can do to solve itl
The City of Renton maintains an active public education and outreach program
with a variety of approaches to inform residents, businesses and developers about
• ways to prevent stormwater pollution. The program has been developed locally
with input from regional organizations such as the STORM group, King County,
WRIA 8 Salmon Recovery Council, WRIA 9 Watershed Ecosystem Forum, the
Department of Ecologly, and the Environmental Protection Agency. The goal of
the education program is to reduce or eliminate behaviors and practices that
cause or contribute to adverse stormwater impacts.
Current Activities .
•
The tables below organize Renton's educational program elements to meet Permit
requirements for subject area and target audience. A list with descriptions'of
each program element follows the tables.

(eliminating drips and carwash wastewater from surface waters), (3) home care
(pesticides, herbicides, etc.). [Target Audience: General Public, Homeowners, City
staff]
Storm Drain Marking: In 2009, the Surface Water Utility began a volunteer storm drain
marker program. The intent is to educate citizens about how the stormwater system
functions, and how people's understanding and behaviors are essential to preventing
pollutant materials from entering the storm drains, and ultimately into stream, river, lake
and sound waters. Through this program, City staff coordinates volunteer groups to
install markers with the 'Puget Sound Starts Here'logo on drain inlets. [Target
Audience: General Public, Homeowners]
FLYER—10 Things You Can Do To Prevent Stormwater Pollution: The storm drain
marker volunteers also distribute informational flyers to local homeowners. The flyers
provide information on changing behaviors and practices to protect stormwater quality.

well as to evaluate changes in adoption of the targeted behaviors. Renton's
compliance is found in the following:
- The City is measuring the understanding and adoption of the targeted behaviors
and targeted audiences listed below with specific measurements for each
program. The resulting measurements will be used to direct education and
outreach resources more effectively, as well as to evaluate changes in adoption of
the targeted behaviors.
Target Audience: General Public-Storm Drain Marker Volunteers
Subject Area: Source control BMPs and environmental stewardship actions and
opportunities in the areas of pet waste, vehicle maintenance and landscaping..
Program Description: In 2010, the City initiated a program to educate the
general public through a volunteer program to install storm drain markers and •
(for selected projects) distribute educational flyers to residences in the area of
installation. The markers are labeled with the Puget Sound Starts (PSSH) logo.
The flyers feature an image of the Drain Markers, which helps residents make the
connection between the flyer content and the markers installed in their
neighborhood. The flyer reflects the PSSH message that individuals can make a
difference by making small changes to their daily behaviors. It describes 10
things that individuals can do to prevent stormwater pollution, including
categories of car maintenance,pet waste management and yard care.
Program Measurement: The effectiveness of the Drain Marker Volunteer
program to encourage the targeted audience to adopt changes is measured by
surveying the volunteer groups.
Target Audience: General Public-Natural Yard Care Workshops
Subject Area: To increase residents'knowledge of"best practices"for managing
their yards.
Program Description: Renton's Natural Yard Care program targets alternative
yard care practices with emphasis on reducing or eliminating
pesticides/herbicides and chemical fertilizers, and efficient use of water for
gardens. The 2010 program workshops were designed to teach Renton citizens
King County's designated "best practices"for landscape management through a
sequence of four free, subject-specific workshops offered from mid-September to
early November.
Program Measurement: Each of the four Natural Yard Care workshops was
individually evaluated through a pre-and post-workshop survey. The pre-
workshop surveys measured attendees'existing knowledge and practice of
specific natural yard care techniques. Following each workshop, respondents
were asked to consider how often they would practice specific techniques in the
future. Individuals who wished to win free natural yard care prizes were asked
to complete an additional Natural Yard Care Pledge form.

The City of Renton's 21010 Natural Yard Care program was successful for the
following reasons:
o All four workshop presenters addressed King County's Five Steps to
Natural Yard Care through unique content material. This four-workshop
series was designed to teach the public about King County's basic steps to
practice natural yard care. Each of the four presenters covered at least
three of these principles while offering their own expertise and personal
touch to make each workshop unique and interesting.
o Overall works op attendance was high. In 2009, the City of Renton
hosted one Na lural Yard Care workshop that was attended by twenty-five

pipeline hydrostatic test water. Planned discharges will be de-
chlorinated]to a concentration of 0.1 ppm or less,pH-adjusted, if
necessary, d volumetrically and velocity controlled to prevent re-.
suspension of sediments in the MS4.
• Discharges from lawn watering and other irrigation runoff. These will
be minimized through, at a minimum,public education activities (see
Section 1) an' water conservation efforts.
• Dechlorinated swimming pool discharges.The discharges will be
dechlorinated to a concentration of 0.1 ppm or less,pH-adjusted and
reoxygenizled if necessary, volumetrically and velocity controlled to
prevent re-suspension of sediments in the MS4. Swimming pool
cleaning w� stewater and filter backwash will not be discharged to the
MS4.
• Street and sidewalk wash water, water used to control dust,and routine
external building wash down that does not use detergents. The City
will reduce these discharges through, at a minimum, public education
activities (see section 1) and/or water conservation efforts. To avoid
washing pollutants into the MS4,the City must minimize the amount
of street wash and dust control water used. At active construction sites,
street sweeping must be performed prior to washing the street.
• Other non-�tormwater discharges. The discharges will be in .
compliance with the requirements of the stormwater pollution
prevention plan reviewed by the City, which addresses control of
construction site de-watering discharges.
iii. The City's SWMP will, at a minimum, address each category in ii above
in accordance with the conditions stated therein.
iv. The SWMP will further address any category of discharges in i or ii
• above if the discharges are identified as significant sources of pollutants
to waters of the State.
v. The ordinance or other regulatory mechanism will include escalating
enforcement procedures and actions.
vi. The City will]develop an enforcement strategy and implement the.
enforcement provisions of the ordinance or other regulatory mechanism.
Following are details about the City's ordinance complying with these permit
requirements:
City Ordinance #5478 prohibits non-stormwater, illegal discharges,and/or
dumping into the City's municipal separate storm sewer system, surface waters,
June 2010 • - Page 23
City of Renton Storm 2010 Storm Water Mairdgement Plan
and ground water. City Ordinance #5478 was authorized on August 3, 2009, to
meet the adoption permit deadline of August 16, 2009. The ordinance includes
adoption of the 2009 King County Stormwater Pollution Prevention Manual. In
February, these discharge prohibition regulations were continued with the
adoption of Ordinance #5526(effective date of February 10, 2010). Ordinance
#5526 amends the City stormwater code with new surface water design standards
for new development, redevelopment and construction sites: These ordinances
meet the requirements of NPDES Phase II Permit Condition S5.C 3.b, including
escalating enforcement procedures and actions.
Because the Phase II permit requires the City to fully implement its IDDE
program by August 19, 2011, this section presents general activities for on-going
development of an IDDE program; however, specific activities will be identified
and planned for 2010 and beyond to meet IDDE program related deadlines.
Currently, the City runs a telephone dispatch service through the Police
Department that allows residents to call in and report a spill that will constitute a
threat to human health, the environment, and welfare anytime. Other storm
drainage problems can be reported via this phone number or other published
phone numbers even after hours. The dispatcher relays the message to the
respective City department and division responsible for response to that call. The
City tracks the call and whether there is a response to any actions necessary, or
whether enforcement is needed. In addition, the City has a published phone
number and email that allows the public to post questions and problems through
the City's website. The City plans to evaluate the hotline procedures, and update,
formalize, and document new protocols.
Additional IDDE program elements include continuing outreach efforts to
• educate the public on IDDE and how public actions affect the downstream
conditions, on-going staff training on IDDE problems and how to identify and
resolve the problems, and summarizing what steps the City is implementing in
each annual report'and SWMP document provided to Ecology. The City also
plans to develop an outfall screening program prior to the end of the first permit
term.
The City currently implements activities and programs associated with IDDE that
complies with much of the program. The current compliance activities
associated with the Permit requirements include:
• City currently has an IDDE program.
• The City has codes and standards that address illicit discharges and civil
infractions.
• The City has an existing stormwater page on the City website.
• The City maintains an up-to-date storm map with continual mapping
occurring. The City has a standard operating procedure for keeping the
June 2010 Page 24
ll•
City of Renton Storm 2010:Storm Water Management Plan
municipal separate storm sewer system map and inventory up-to-date. The
map is updated with new facilities or corrected for inconsistencies based
on field verification.
• The City has a24-hour hotline (425-430-7400), through the Police
Department that allows citizens to call in with surface water complaints
including illicit discharges,flooding, and other surface water related
issues. A tracking mechanism currently receives these calls and routes
them to appropriate City departments. The City plans on reviewing
current and futire public education and outreach programs for minimizing
pollutant discharges, creating IDDE training program, reviewing updated
IDDE codes to comply with the Permit, tracking and reporting issues that
arise throughout all City departments affecting IDDE.
Ongoing IDD&E Program (S5.C.3.c)
The City will develop and implement an ongoing program to detect and address
non-stormwater discharges, spills, illicit connections and illegal dumping into the
City's municipal separate storm sewer system. The program will be fully
implemented no later than August 19,2011, and will include:
i. Procedures for locating priority areas likely to have illicit discharges,
including at a minimum: evaluating land uses and associated
business/industrial activities present; areas where complaints have been
registered in the past; and areas with storage of large quantities of materials
that could result in spills.
ii. Field assessment activities, including visual inspection of priority outfalls
identified in i, above, during dry weather and for the purposes of verifying -
outfall locations l identifying previously unknown outfalls, and detecting
illicit discharges'
• Receiving waters will be prioritized for visual inspection no later than
three years from February 16,2009, with field assessments of three
high priority water bodies made no later than February 16,2011. Field
assessments on at least one high priority water body will be made each
year thereafter.
• Screening for illicit connections will be conducted using: "Illicit
Discharge Detection and Elimination:A Guidance Manual for Program
Development and Technical Assessments", Center for Watershed
• Protection, October 2004, or another methodology of comparable
effectiveness.
The City of Renton Surface Water Utility has prioritized City receiving waters for
•
visual inspection to determine the potential severity of illicit discharge problems
in the municipal separate storm sewer system. The methodology used was based
on a desktop assessment described in Illicit Discharge Detection and Elimination:
• A Guidance Manual for Program Development and Technical Assessments,
Center for Watershed Protection, October 2004.
June 2010 Page 25
City of Renton Storm 2010 Storm Water Management Plan
The Surface Water Utility has conducted outfall assessments of three high priority
basins. The Surface Water Utility will continue outfall assessments for at least
one high priority basin per year.
iii. Procedures for characterizing the,nature of, and potential public or
environmental threat posed by, any illicit discharges found by or reported to
the City. Procedures will include detailed instructions for evaluating
whether the discharge must be immediately contained and steps to be taken
for containment of the discharge.
Compliance with this provision will be achieved by investigating(or
referring to the appropriate agency) within 7 days, on average, any
complaints, reports or monitoring information that indicates a potential
illicit discharge, spill, or illegal dumping; and immediately investigating(or.
referring)problems and violations determined to be emergencies or
otherwise judged to be urgent or severe.
The City has developed Spill Response Standard Operating manual. This
manual provides City staff with standard operating procedures for responding to
spills within the City that threaten the storm drain system. It includes actions
that City staff will take to comply with reporting requirements of the Department
of Ecology's Western Washington Phase II Municipal Stormwater Permit
(Condition G3).
iv. Procedures for tracing the source of an illicit discharge; including visual
inspections, and when necessary, opening manholes, using mobile cameras,
collecting and analyzing water samples, and/or other detailed inspection
procedures.
The City currently follows procedures for tracing the source of an illicit
discharge without documentation. Formal documentation of procedures will be
developed prior to permit deadline.
v. Procedures for removing the source of the discharge; including
notification of appropriate authorities; notification of the property owner;
technical assistance for eliminating the discharge; follow-up inspections;
and escalating enforcement and legal actions if the discharge is not •
eliminated. -
Compliance with this provision will be achieved by initiating an
investigation within 21 days of a report or discovery of a suspected illicit
connection to determine the source of the connection,the nature and
volume of discharge through the connection, and the party responsible for
the connection. Upon confirmation of the illicit nature of a storm drain
connection,termination of the connection will be verified within 180 days,
using enforcement authority as needed.

• provides escalating enforcement and legal actions if a discharge is not
eliminated.
The City plans on continuing review and development of its IDDE program .
including developing a written procedures program that includes field assessing,
identification of illicit discharges, communicating to various stakeholders,
configuring and deplo ing IDDE response system, tracking/resolving the system
tie-ins, reporting top Toper personnel (internally and externally), coordinating
with various permit and resource agencies, and summarizing actions/results to all
stakeholders. .
Each incident should be immediately characterized accordingly into a response
matrix that-addresses fall of the above IDDE components. The City plans on
reviewing and further developing its IDDE program by complying with the
NPDES permit requirements.
Public Information (S5.C.3.d)
The City will inform public employees,businesses, and the general public of
hazards associated wish illegal discharges and improper disposal of waste.
i. No later than August 19,2011,the City will distribute appropriate
information to target audiences identified pursuant to Section 1.
ii. No later than February 16,2009,the City will publicly list and
publicize a hotline or other local telephone number for public reporting
of spills and other illicit discharges. The City will keep a record of calls
received and follow-up actions taken in accordance with Section 3.c.ii.
through v. above; and will include a summary in the annual report(see
section S9 of the City's Permit,Reporting and Record Keeping
Requirementlls).
Information on illegaldischarges and proper disposal are currently provided to
targeted businesses aid general public. Information is provided through the City
website: Surface Water Utility webpage (Puget Sound Starts Here); Water Utility .
webpage (water quality and conservation); and link to King County Local
Hazardous Waste management program. Additionally, the City has produced and
distributed flyers to residences and homeowners associations. A complete •
program will be implemented within permit deadline.
The City has evaluated the current hotline procedures, updated the phone
numbers, and documented the protocols. The City webpage has been updated to
add the 24-hour hotline information encouraging citizens to report illegal
discharges or illicit dumping to protect water quality. The calls to the hotline are
- usually recorded and distributed to the appropriate response authority according
to a spill response matrix.
Program Evaluation and Assessment (S5.C.3.e)
The City will adopt and implement procedures for program evaluation and
assessment, including tracking the number and type of spills or illicit discharges
June 2010 Page 27
•
City of Renton Storm 2010 Storm Water Management Plan
identified; inspections made; and any feedback received from public education
efforts. A summary of this information will be included in the City's annual report
(see section S9 of the City's Permit, Reporting and Recordkeeping
Requirements).
The City is in compliance. The City tracks identified IDDE incidents. The City is
also implementing an improved asset management database that will log incident
responses with work orders that can access GIS stormwater assets.
' Training for Municipal Staff(S5.C.3.f)
The City will provide appropriate training for municipal field staff on the
identification and reporting of illicit discharges into MS4s.
i. No later than August 16,2009,the City will ensure that all municipal field
staff who are responsible for identification, investigation,termination,
cleanup, and reporting illicit discharges, including spills, improper
disposal and illicit connections are trained to conduct these activities.
Follow-up training will be provided as needed to address changes in
procedures, techniques or requirements. The City will document and
maintain records of the training provided and the staff trained.
Public Works Maintenance Division staff is trained in identifying,
investigating, and cleaning up illicit discharges. On-going IDDE and BMP
trainings are included in routine Public Works Maintenance staff safety
meetings. This training emphasizes the importance of Best Management
Practices, good housekeeping, and spill response.
ii. No later than February 16, 2010, an ongoing training program will be
developed and implemented for all municipal field staff, which, as part of
their normal job responsibilities, might come into contact with or
otherwise observe an illicit discharge or illicit connection to the storm
sewer system will be trained on the identification of an illicit
discharge/connection, and on the proper procedures for reporting and
responding to the illicit discharge/connection. Follow-up training will be
provided as needed to address changes in procedures, techniques or
requirements. The City will document and maintain records of the training
provided and the staff trained.
The City has a training program that is assessed and planned during each
employee's yearly performance review. The training review implements an
ongoing employee training to more efficiently affect their abilities out in the
field to assess stormwater maintenance issues which includes the City's IDDE
program.
Across City departments,field employees have received training informing
them about the importance of the NPDES program, and recognizing,
reporting, and responding to illicit discharges and connections.
Staff has received training produced by American Public Works Association,
Washington Department of Ecology and Environmental Protection Agencies,
June 2010 Page 28
City of Renton Storm 2010 Storm Water Management Plan
as well as training adapted from Snohomish County, and other sources for the
City's on-going IDDE training program for field staff.
Additionally,field sand in-house staff are certified on erosion and sediment
control techniques that further assists in controlling runoff.
These trainings enable City employees to enhance their knowledge base on
IDDE, controlling runoff, ordinances, monitoring, etc.

Section 5: Controlling Runoff from New Development,
Redevelopment and Construction Sites (S5.C.4)
The City will develop, implement, and enforce a program to reduce pollutants in
• stormwater runoff to its MS4 from new development, redevelopment and construction
site activities. This program will be applied to all sites that disturb a land area 1 acre or
greater, including projects less than one acre that are part of a larger common plan of the
development or sale. The program will apply to private and public development,
including roads. The "Technical Thresholds" in Appendix 1 of the City's Permit will be
applied to all sites 1 acre or greater, including projects less than one acre that are part of a
larger common plan of the development or sale.
The City will take the following actions and conduct the following activities:
Ordinance (S5.C.4.a)
The program will include an ordinance or other enforceable mechanism that
addresses runoff from new development,redevelopment, and construction site
projects. Pursuant to S5.A.2. of the Permit an ordinance or other regulatory.
mechanism will be in place prior to August 16, 2009. Existing City
requirements to apply stormwater controls at smaller sites, or at lower
thresholds than required pursuant to Section 4, will be retained. In addition,
existing City ordinances will remain in place that currently may meet or
exceed the minimum Permit requirements. The ordinance or other
enforceable mechanism will be in place no later than August 16, 2009. The
ordinance or other enforceable mechanism will include, at a minimum:
The City has an active program to reduce pollutants in stormwater runoff
from new developments, redevelopments and construction site activities. The
existing program applies to both public and private projects.
i. The Minimum Requirements,technical thresholds, and definitions
in Appendix 1 of the City's Permit or an equivalent approved by
Ecology under the NPDES Phase I Municipal Stormwater Permit,
for new development,redevelopment, and construction sites.
Adjustment and variance criteria equivalent to those in Appendix 1
of the City's Permit will be included. More stringent requirements
may be used, and/or certain requirements may be tailored to local
circumstances through the use of basin plans or other similar water
• quality and quantity planning efforts. Such local requirements will
provide equal protection of receiving waters and equal levels-of
pollutant control to those provided in Appendix 1 of the City's
Permit.
On February 1, 2010, the City of Renton adopted Ordinance #5526. This
ordinance amends the City stormwater code with new surface water
design standards for new development, redevelopment and construction
sites. As written in this ordinance, Renton adopted the 2009 King County
Surface Water Design Manual, with City Amendments. The amendments
June 2010 Page 30
•
/ J
City of Renton Storm 2010 Storm Water Management Plan
to the King County Surface Water Design Manual clarify requirements
that are specific to Renton and are different from the county manual. •
The manual ensures that all developments including development less
than one acre exceeding the thresholds defined in Appendix I of the
Permit comply with all minimum requirements per section•S5.C.4.a of the
Phase II NPDES permit.
ii. A site planning process and BMP selection and design criteria that,
when used to implement the minimum requirements in Appendix 1
of the City's Permit(or equivalent approved by Ecology under the
Phase I Permit)will protect water quality, reduce the discharge of
pollutants to the maximum extent practicable and satisfy the State
requirement under Chapter 90.48 RCW to apply all known,
available and reasonable methods of prevention, control and
treatment(AKART)prior to discharge. The City will document how
the criteria and requirements will protect water quality, reduce the
discharge of pollutants to the maximum extent practicable, and
satisfy State AKART requirements.
Ordinance 5526, described above (S5.C.4.a.i), meets this requirement.
iii. The legal authority,through the approval process for new
development, to inspect private stormwater facilities that discharge to the
•
City's MS4.
City of Renton Ordinance #5526 requires new,private stormwater
facilities to gifant permission to the City for inspection purposes. The
updated SWDM requires permit applications to include a Declaration of
Covenant for Maintenance and Inspection of Flow Control BMPs.
iv. Provisions to allow non-structural preventive actions and source .
reduction approaches such as Low Impact Development Techniques
(LID),n easures tominimizethe creation of impervious surfaces
and measures to minimize the disturbance of native soils and
vegetation. Provisions for LID should take into account site
conditions, access and long term maintenance.
The updated SWDM includes LID techniques to minimize creation of
impervious surfaces. The City of Renton requires the implementation of
Low Impact Development alternatives such as dispersion and infiltration
for new development and redevelopment projects when feasible to
mitigate for all target surfaces.
v. If the City chooses to allow construction sites to apply the
"Erosivity Waiver" in Appendix 1 of the City's Permit, Minimum
Requirement#2,the ordinance or regulatory mechanism will
include appropriate, escalating enforcement sanctions for
construction sites that provide notice to the City of their intention to
apply the waiver but do not meet the requirements (including
June 2010 Page 31
City of Renton Storm 2010 Storm Water Management Plan
timeframe restrictions, limits on activities that result in non-
stormwater discharges, and implementation of appropriate BMPs to
prevent violations of water quality standards)to qualify for the
waiver.
As written into the City's updated Surface Water Design Manual,
waivers are not permitted The City of Renton requires all projects to
comply with sediment and erosion control(core requirement#5),
including small projects. Appendix D describes Sediment and erosion
control measures applicable to all projects not qualifying for small
project drainage review. Projects that trigger small project drainage
review, shall comply with the sediment and erosion control criteria
described in Appendix C (small project drainage review).
Permitting Process (S5.C.4.b)
The program will include a permitting process with plan review, inspection
and enforcement capability to meet the standards listed in(i)through(iv).
below, for both private and public projects, using qualified personnel (as
defined in Definitions and Acronyms). At a minimum,this program will be
applied to all sites that disturb a land area one acre or greater, including
projects less than one acre that are part of a larger common plan of the
development or sale. The process will be in place no later than August 16,
2009.
i. Except as provided in Section 4.b.vii. below, review of all
stormwater site plans for proposed development activities.
The City has a review process for all of its stormwater site plans for
proposed development activities. The clearing and grading code and the "
drainage code address construction site temporary erosion and
sedimentation control. In addition, the construction of permanent storm
flow control and water quality treatment facilities are reviewed by the
City during the permit review process and construction activities.
Monitoring is recorded by City inspectors. The City Surface Water
Utility and Development Services Plan Review Sections provides
drainage review of new developments and redeveloped site plans to
ensure compliance with all sections of the City adopted 2009 King
County Surface Water Design Manual and City Amendments.
ii. Except as provided in Section 4.b.vii. below, inspect,prior to
clearing and construction, all known development sites that have a
high potential for sediment transport as determined through plan
review based on definitions and requirements in Appendix 7 of the
City's Permit,Identifying Construction Site Sediment Transport
Potential.
Areas where the City knows of high potential for sediment transport have
been determined within the City. New annexed areas will be evaluated
on an on-going project basis with new developments having high
June 2010 Page 32
City of Renton Storm 2010 Storm Water Management Plan
erosivity areas marked. All new developments are brought through the
plan review process which includes a requirement on providing for BMPs
to control erosivity.
iii. Except as provided in Section 4b.vii. below, inspect all known
• permitted development sites during construction to verify proper
installation and maintenance of required erosion and sediment
controls. Enforce as necessary based on the inspection.
Inspection offrojects is assigned through the assignment of a City
construction rirspector for all projects requiring a Public Works
Construction IPermit to inspect on-site erosion and sediment control
BMPs.
iv. Inspect all permitted development sites upon completion of
construction'and prior to final approval or occupancy to ensure
proper installation of permanent stormwater controls such as
stormwater facilities and structural BMPs. Also,verify a
maintenance plan is completed and responsibility for maintenance is
- assigned. Enforce as necessary based on the inspection.
The City inspectors conduct a final inspection of all newly constructed
stormwater facilities, redlines any discrepancies between what was
•
constructed and the plans, and turns the plans over to maintenance
personnel fort final redlines prior to final approval or occupancy.
Currently, inspection logs are kept for each project. The existing
inspection recordkeeping process is being reviewed for potential
overhaul.
v. Compliance with the inspection requirements in ii, iii and iv above
will be determined by the presence and records of an established
inspection program designed to inspect all sites and achieving at
least 95%of scheduled inspections.
vi. An enforcement strategy will be developed and implemented to
respond to issues of non-compliance.
vii. If the City chooses to allow construction sites to apply the
"Erosivity Waiver"in Appendix 1 of the City's Permit, Minimum
Requirement#2,the City is not required to review the construction
stormwater pollution prevention plans as part of the site plan review
in(i) above, and is not required to perform the construction phase
inspections identified in(ii) and(iii) above related to construction
sites which are eligible for the erosivity waiver. -
As written into the updated SWDM, waivers are not permitted, all
development project submittals need to include sediment and erosion
control measures. -
June 2010 Page 33
City of Renton Storm 2010 Storm Water Management Plan
Long-term Operation and Maintenance (S5.C.4.c)
The program will include provisions to verify adequate long-term operation
and maintenance (O&M) of post-construction stormwater facilities and BMPs
that are permitted and constructed pursuant to (b) above. These provisions will
be in place no later than February 16, 2009 and will include:
i. Adoption of an ordinance or other enforceable mechanism that
clearly identifies the party responsible for maintenance,requires
inspection of facilities in accordance with the requirements in(ii)
through (iv)below, and establishes enforcement procedures.
ii. The City will establish maintenance standards that are as protective
as or more protective of facility function than those specified in
Chapter 4 of Volume V of the 2005 Stormwater Management
Manual for Western Washington. For facilities which do not have
maintenance standards, the•City will develop a maintenance
standard.
(1) The purpose of the maintenance standard is to determine if
maintenance is required. The maintenance standard is not a
measure of the facilities required condition at all times between
inspections. Exceeding the maintenance standard between the
period of inspections is not a Permit violation.
(2) Unless there are circumstances beyond the City's control, when
an inspection identifies an exceedance of the maintenance
standard, maintenance will be performed:
❑ Within 1 year for wet pool facilities and retention/detention
ponds.
❑ Within 6 months for typical maintenance.
❑ Within 9 months for maintenance requiring re-vegetation.
❑ Within 2 years for maintenance that requires capital
construction of less than$25,000.
Circumstances beyond the City's control include denial or
delay of access by property owners, denial or delay of
necessary permit approvals, and unexpected reallocations of
maintenance staff to perform emergency work. For each
exceedance of the required timeframe,the City must document
the circumstances and how they were beyond their control.
iii. Annual inspections of all stormwater treatment and flow control
_ facilities (other than catch basins)permitted by the City according to
Section 4.b. unless there are maintenance records to justify a
different frequency.
Reducing the inspection frequency will be based on maintenance
records of double the length of time of the proposed inspection
frequency. In the absence of maintenance records,the City may
June 2010 Page 34
% r /
•
City of Renton Storm 2010 Storm Water Management Plan
substitute written statements to document a specific less frequent
inspection schedule.Written statements will be based on actual
inspection and maintenance experience and will be certified in
accordance with G19 of the City's Permit, Certification and
Signature.
iv. Inspections of all new flow control and water quality treatment
facilities, including catch basins, for new residential developments
that area part of a larger common plan of development or sale,
every 6 Months during the period of heaviest house construction
(i.e., 1 to 2 years following subdivision approval) to identify
maintenance needs and enforce compliance with maintenance
standards as needed.
•
City of RentorliOrdinance #5526 identifies the party responsible for
maintenance and requires inspection of facilities. Per the updated
SWDM, applicants will submit a declaration of covenant that identifies
maintenance responsibilities, and right of inspection and maintenance.
City operatiois and maintenance crews apply BMPs to containing and
minimizing pollutant runofffrom municipal operations. City
responsibilities include inspections of problem areas, inspections of
customer coni laints, and maintaining areas via vactoring out the
pollutants fro problem areas each year.
The City currently inspects private flow control and treatment facilities
during plat construction. All new constructed facilities will be inspected
as required per the updated Surface Water Design Manual standards.
The standards require the developer to post a two-year maintenance and
defect bond. T he City has funded a position to address inspections of
new facilitiespermitted under the updated Surface Water Design Manual.
•
The City is also developing improvements to its GIS database, is
implementing a new assets management database, and is investigating
acquisition of a new permits management database ._
Municipal operation and maintenance activities related to utility
installations, street cleaning, ditch maintenance and other City activities
include, but are not limited to public streets, receiving public/private
parcels, and parking.
The Surface ,Water Utility Maintenance Section currently has 12 FTEs,
three vactor trucks and other equipment used to maintain and operate
publicly owned stormwater management systems and facilities.
Record Keeping (S5.C.4.d) •
The program will;include a procedure for keeping records of inspections and
enforcement actions by staff, including inspection reports, warning letters,
notices of violations, and other enforcement records. Records of maintenance
inspections and maintenance activities will be maintained. The City will keep
June 2010 Page 35
City of Renton Storm 2010 Storm Water Management Plan
records of all projects disturbing more than one acre, and all projects of any
size that are part of a common plan of development or sale that is greater than
one acre that are approved after February 16,2007.
The City maintains a record keeping system that includes permitting,
•
enforcements, and construction inspections on private and public facilities
construction projects. This is done through the City's code compliance
process.
Currently, the City crews utilize a Maintenance Management System (MMS)
that records time and resources spent on all cleaned pipelines, catch basins,
ditches, replaced storm pipelines, cleaned vaults, and cleaned ponds related
to the City's O&M activities. In addition, the City records areas cleaned and
inspected on a yearly basis via paper maps.
Additionally, the City is developing improvements to its GIS database, is
implementing a new assets management database, and is investigating
acquisition of a new permits management database. In 2010, the City
implemented a new MMS system (Enterprise Access Maintenance) that
integrates with the GIS for future operations activities. In 2009, the City
initiated a$680,000 Storm System Mapping Project to improve the mapping
and inventory of the City's storm system. This project includes filling in
necessary field mapping information of unknown system areas. The mapping
project is scheduled to continue through 2010.
Availability of NOIs (S5.C.4.e)
The City will make available copies of the "Notice of Intent for Construction
Activity" and copies of the "Notice of Intent for Industrial Activity" to
representatives of proposed new development and redevelopment. The City
will continue to enforce local ordinances controlling runoff from sites that are
- ,also covered by stormwater permits issued by Ecology.
NOI forms and information are currently provided within the City's
Department of Community &Economic Development(Development Services
Division). Currently, Development Services directs proposed new and
redevelopment projects to obtain these NOIs.
Development Services will now also provide information and NOI forms from
the new Surface Water Design Manual to applicants at pre-application
meetings to make them aware of this requirement if it is obvious that the
project will be disturbing more than one acre of land or more.
Training (S5.C.4.f)
No later than August 16, 2009,the City will verify that all staff responsible for
implementing the program to control stormwater runoff from new
development,redevelopment, and construction sites, including permitting,

plan review, construction site inspections, and enforcement, are trained to'
conduct these activities. Follow-up training will be providedas needed to
address changes in procedures,techniques or staffing. The City will document
and maintain records of the training provided and the staff trained.
Ongoing operations and maintenance training is currently provided, and
documented for fuiure annual compliance program reports. Curricula and
staff training requirements for pollution prevention are currently on-going in-
house and will be,supplemented with further classes as offered through
resources such as Regional Road Maintenance -Endangered Species Act

City of Renton Storm 2010 Storm Water Management Plan
Section 6: Pollution Prevention and Operation and
Maintenance for Municipal Operations (S5.C.5)
By February 16, 2010,the City will develop and implement an operations and
maintenance (O&M)program that includes a training component and has the ultimate
goal of preventing or reducing pollutant runoff from municipal operations.
The City will take the following actions and conduct the following activities:
Maintenance Standards (S5.C.5.a)
The City will establish maintenance standards that are as protective as or more
protective, of facility function than those specified in Chapter.4 of Volume V
of the 2005 Stormwater Management Manual for Western Washington. For
facilities which do not have maintenance standards,the City will develop a
maintenance standard.
i. The purpose of the maintenance standard is to determine if
maintenance is required. The maintenance standard is not a measure
of the facilities required condition at all times between inspections.
Exceeding the maintenance standard between inspections and/or
maintenance is not a Permit violation.
ii. Unless there are circumstances beyond the City's control, when an
inspection identifies an exceedance of the maintenance standard,
maintenance will be performed:
• • _ ❑ Within 1 year for wet pool facilities and retention/detention ponds.
❑ Within 6 months for typical maintenance.
❑ Within 9 months for maintenance requiring re-vegetation.
❑ Within 2 years for maintenance that requires capital construction
of less than$25,000.
•
Circumstances beyond the City's control include denial or delay of access by
property owners, denial or delay of necessary permit approvals, and
unexpected reallocations of maintenance staff to perform emergency work.
For each exceedance of the required timeframe, the City will document the
circumstances and how they were beyond their control.
Maintenance standard guidelines are established to comply with the permit
requirements within three years of the effective date of the Permit
(February 16, 2010). These maintenance standards contain the following:
1. Training for maintenance staff emphasizes IDDE, and sediment and
erosion control practices.
2. Maintenance standards for inspecting facilities. Effective February 10,
2010, the City adopted the 2009 King County Surface Water Design
Manual, including Appendix A -maintenance standards. The City also
adopted by reference the 2009 King County Stormwater Pollution
Prevention Manual. The City currently follows an Integrated Pest
June 2010 -Page 38
City of Renton Storm 2010 Storm Water Management Plan
•
Management policy for City-owned facilities that contains guidance and -
standard operating procedures for applying fertilizer and/or pest
spraying, and,storing chemicals, and sediment/erosion control. The City
Parks Department is a certified Audubon Cooperative Sanctuary.
3. All known municipally owned or operated treatment and flow control •
facilities are inspected and maintained at a minimum, annually.
4. Total inspection of all catch basins and inlets owned by the City-at least
once prior to the end of the Permit term with cleaning conducted on them
•
if they are de file
out of compliance with the maintenance standards.
5. Erosion and.sediment control of City projects and facilities are followed.
according to SWPPPs developed for each project that are greater than
one acre in size and smaller projects, if drainage review is required, that
includes the erosion control plans,practices, and procedures. In
addition, general erosion and sediment control practices are followed
according to the City's Operations Manager, who is a CESCL.
General Inspections (S5.C.5.b)
Annual inspection of all municipally owned or operated permanent
stormwater treatment and flow control facilities, other than catch basins, and
taking appropriate maintenance actions in accordance with the adopted
maintenance standards. The annual inspection requirement may be reduced
based on inspectioi records.
Reducing the inspection frequency will be based on maintenance records of
double the length of time of the proposed inspection frequency.,In the absence
of maintenance records,the City may substitute written statements to
document a specific less frequent inspection schedule. Written statements will
be based on actual]inspection and maintenance experience and will be
certified in accordance with G19 of the City's Permit, Certification and
Signature.
Maintenance staff inspects and maintains public owned treatment and flow
control facilities pier adopted King County Storm Water Design Manual,
Appendix A. Facilities are inspected annually. Inspections are done more
frequently at historical problem areas within the City. Maintenance is
performed as needed per inspection results.
Post-Storm Inspections (S5.C.5.c)
Spot checks of potentially damaged permanent treatment and flow control
facilities (other than catch basins) after major(greater than 24-hour-10-year
recurrence interval rainfall) storm events. If spot checks indicate widespread
damage/maintenance needs, inspect all stormwater treatment and flow control
facilities that maybe affected. Conduct repairs or take appropriate
maintenance action in accordance with maintenance standards established
above,based on the results of the inspections.
June 2010 . • Page 39
City of Renton Storm 2010 Storm Water Management Plan
Major post storm checks are currently a work item of City personnel.
Facilities that typically require post storm maintenance are inspected and
receive sediment cleaning as needed following major storms.
• Catch Basins and Inlet Inspections (S5.C.5.d)
Inspection of all catch basins and inlets owned or operated by the City at least
once before the end of the City's Permit term. Clean catch basins if the
inspection indicates cleaning is needed to comply with maintenance standards
established in the 2005 Stormwater Management Manual for Western
Washington. Decant water will be disposed of in accordance with Appendix 6
of the City's Permit, Street Waste Disposal.
Inspections may be conducted on a"circuit basis"whereby a sampling of
• catch basins and inlets within each circuit is inspected to identify maintenance
needs. Include in the sampling an inspection of the catch basin immediately
upstream of any system outfall. Clean all catch basins within a given circuit at
one time if the inspection sampling indicates cleaning is needed to comply
with maintenance standards established under Section 4.c., above.
As an alternative to inspecting catch basins on a"circuit basis,"the City may
inspect all catch basins, and clean only catch basins where cleaning is needed
to comply with maintenance standards.
The City has increased inspection frequencyto comply with the Permit
requirements and to establish a circuit basis for the inspections. When
required, maintenance typically includes pipe cleaning, culvert cleaning, ditch
maintenance, street cleaning, road/pipe repairs, and maintaining roadside
areas including vegetation management.
Compliance (S5.C.5.e)
Compliance with the inspection requirements in a, b, c and d above will be
determined by the presence of an established inspection program designed to
inspect all sites and achieving inspection of 95% of all sites.
These compliance criteria are part of the maintenance and inspection
standards established by the City prior to August 16, 2010.
Reduction of Stormwater Impacts (S5.C.5.f) .
Establishment and implementation of practices to reduce stormwater impacts
associated with runoff from streets,parking lots,roads or highways owned or
maintained by the City, and road maintenance activities conducted by the
City. The following activities will be addressed:
• Pipe cleaning
• Cleaning of culverts that convey stormwater in ditch
systems
• Ditch maintenance
• Street cleaning
June 2010 Page 40

City of Renton Storm 2010 Storm Water Management Plan
• Road repair and resurfacing, including pavement grinding
• Snow and ice control
• Utility installation
• Pas.ement striping maintenance
• • Maintaining roadside areas, including vegetation management
• Dust control
The City currentlyhas an Operations and Maintenance Department that
conducts all of these activities.
Policies and Procedures (S5.C.5.g)
Establishment and implementation of policies and procedures to reduce
pollutants in discharges from all lands owned or maintained by the City and
subject to the City's Permit, including but not limited to: parks, open space,
road right-of-way,maintenance yards, and stormwater treatment and flow
control facilities. These policies and procedures will address,but are not
limited to:
• Application of fertilizer, pesticides, and herbicides including
the development of nutrient management and integrated pest
management plans.
• Sediment and erosion control.
• Landscape maintenance and vegetation disposal.
• Trash management.
• •
• Building exterior cleaning and maintenance.
The City currently possesses and follows a documented Integrated Pest
Management policy that is applied to parks and open spaces. In addition,
erosion control is applied upon projects to control sediment-laden runoff on
City projects as well as private development projects. The City Parks
Department is a certified Audubon Cooperative Sanctuary.
Training for maintenance staff emphasizes IDDE, and sediment and erosion
control practices. Maintenance staff are state licensed applicators.
The City's Public Works Maintenance Division has committed to the Regional
ESA Road Maintenance BMP Guidelines.
City projects and drainage facility maintenance are regulated by the City's
adopted Surface Water Design Manual.
The City adopted by reference the 2009 King County Stormwater Pollution
Prevention Manual. [City of Renton Ordinance #5478, August 3, 2009 and
Ordinance #5526,'February 10, 2010].
Training (S5.C.5.h)
Develop and implement an on-going training program for employees of the
City whose construction,operations or maintenance job functions may impact
stormwater quality. The training program will address the importance of
protecting water quality,.the requirements of'the City's Permit, operation and
June 2010 Page 41
City of Renton Storm 2010 Storm Water ME'.n 'gement Plan
maintenance standards, inspection procedures, selecting appropriate BMPs,
ways to perform their job activities to prevent or minimize impacts to water
quality, and procedures for reporting water quality concerns, including
potential illicit discharges. Follow-up training will be provided as needed to
address changes in procedures,techniques or requirements. The City will ,
document and maintain records of training provided.
The City has maintenance crews who attend training programs emphasizing
erosion control, maintenance recording, documenting, spill prevention,
recognizing and reporting illicit discharge detections, and inspections.
Additionally,i the Maintenance Department attends the County Road
Standards and Compliance meetings in order to apply the latest in developing
of set maintenance standards. Future'training programs will be recorded by
the Maintenance Manager.
Existing training staff programs will be reviewed periodically to determine if
they need to be modified or if new training is necessary to maintain
compliance with the permit requirements.
Special Facility Requirements (S5.C.5.i)
•
Development and implementation of a Stormwater Pollution Prevention Plan
•
(SWPPP) for all heavy equipment maintenance or storage yards, and material
storage facilities owned or operated by the City in areas subject to the City's
Permit that are not required to have coverage under the Industrial Stormwater
General Permit. Implementation of non-structural BMPs will begin
immediately after the pollution prevention plan is developed. A schedule for
implementation of structural BMPs will be included in the SWPPP. Generic
SWPPPs that can be applied at multiple sites may be used to comply with this
requirement. The SWPPP will include periodic visual observation of
discharges from the facility to evaluate the effectiveness of the BMP.
The City developed a Stormwater Pollution Prevention Plan (SWPPP)for its
Public Works Maintenance and shops facility. [Implementation date:
February 1, 2010] The Public Works Maintenance and shops facility
accommodates a variety of Public Works buildings and activities, including
vehicle maintenance activities. The site also accommodates storage of Parks
Department equipment and materials, the Police vehicle impound building
and the Animal Control dog kennel.
City staff evaluated and determined that the City-owned Municipal Airport
requires an Industrial Facility NPDES Permit. A SWPPP for the airport
would likely be required under that permit. The City will be planning budget
for and development of an Industrial Facility NPDES Permit application
during 2010.

Record Keeping (S'S.C.5.j)
Records of inspections and maintenance or repair activities conducted by the
City will be maintained in accordance with S9 of the City's Permit, Reporting
Requirements. •
Currently, the City crews utilize a Maintenance Management System (MMS)
that records time and resources spent on all cleaned pipelines, catch basins,
ditches, replaced storm pipelines, cleaned vaults, and cleaned ponds related
to the City's O&M activities. In addition, the City records areas cleaned and
inspected on a yearly basis via paper maps.
Some records of inspections and maintenance or repair activities are
currently kept in project file folders that are kept in storage files along with
the project contents. In the future, inspections/maintenance and repair
activities are to be provided in one storage area that can be easily accessible
per S9 of the Permit.
The City is developing improvements to its GIS database, and is implementing
a new assets management database. In 2010, the. City is implemented a new
MMS system (Enterprise Access Maintenance) that integrates with the GIS for
future operations activities. In 2009, the City initiated a$680,000 Storm
System Mapping Project to improve the mapping and inventory of the City's
storm system. This project includes filling in necessary field mapping
information of unknown system areas. The mapping project is schedule to
continue through 2010.

Section 8: Monitoring 5
A. Permittees are not required to conduct water sampling or other testing during the
effective term of this Permit,with the following exceptions:
1. Any water quality monitoring required for compliance with TMDLs,pursuant to
section S7 Compliance,with Total Maximum Daily Load Requirements and
Appendix 2 of this Permit, and
2. Any sampling or testing required for characterizing illicit discharges pursuant to
section S5.C.3. or S6.D.3. of this Permit.•
S
There is no approved Total Maximum Daily Load(TMDL) applicable to stormwater
discharges from the City's owned and operated storm system.
B. The Permittee shall provide the following information in each annual report:
1. A description of any stormwater monitoring or studies conducted by the Permittee
during the reporting period. If stormwater monitoring was conducted on behalf of
the Permittee, or if studies or investigations conducted by other entities were ,
reported to the Permittee, a brief description,of the type of information gathered or
-received shall be included in the annual report(s) covering the time period(s)the •
information was received.
June 2010 Page 43
City of Renton Storm 2010 Storm Water Mia'r -gement Plan
No stormwater monitoring was conducted during this permit period.

2. An assessment of the appropriateness.of the BMPs identified by the Permittee for
each component of the SWMP; and any changes made, or anticipated to be made,
to the BMPs that were previously selected to implement the SWMP, and why.
The BMPs are appropriate because the permit requires them..
3. Information required pursuant to S8.C.2. below.
C. Preparation for future, long-term monitoring
This section does not apply to secondary permittees. However, secondary permittees
are required to provide information,maps and access for sampling efforts, as
necessary. Secondary permittees are encouraged to participate in the monitoring
program.
1. All cities, towns and counties shall prepare to participate in the implementation of
a comprehensive long-term monitoring program. The monitoring program will
include two components: stormwater monitoring and targeted Stormwater •
Management Program (SWMP) effectiveness monitoring. Stormwater monitoring
is intended to characterize stormwater runoff quantity and quality at a limited
number of locations in a manner that allows analysis of loadings and changes in
conditions over time and generalization across the permittees'jurisdictions.
Stormwater program effectiveness monitoring is intended to improve stormwater
management efforts by evaluating issues that significantly affect the success of, or
confidence in, stormwater controls. The monitoring program can include long-
term monitoring and short-term studies. The results of the monitoring program
will be used to support the adaptive management process and lead to refinements
of the SWMP. •
The City contracted with Herrera Environmental Consultants to develop a monitoring
plan. The plan summarizes site selection and the basic monitoring design for two
components of the long-term monitoring program specified in the National Pollutant
Discharge Elimination System (NPDES) Western Washington Phase II Municipal
Stormwater permit(Ecology 2009a): Stormwater monitoring'(S8.C.1.a) and
Stormwater Management Program Effectiveness (SWMP) monitoring,(S8.C.1.b). The
monitoring plan follows guidance provided in the Washington State Department of
Ecology (Ecology)Monitoring and Reporting Guidance—Phase II Municipal
Stormwater Permits (Ecology 2010). The plan is organized into two main sections
including information related to the stormwater monitoring sites and SWMP
monitoring sites, respectively.
a. Stormwater monitoring
Cities having a population greater than 10,000 and counties having a population
greater than 25,000 shall identify sites for long-term stormwater monitoring.
Adequate sites will be those completely mapped as required in S5.C.3.a. and be
suitable for permanent installation and operation of flow-weighted composite
sampling equipment.No later than December 31, 2010:
June 2010 Page 44
City of Renton Storm 2010 Storm Water Management Plan
i. Each county having a population greater than 100,000 shall identify three
outfalls or conveyances where stormwater sampling could be conducted.
One outfall or conveyance shall represent commercial land use,the second
shall represent 14w-density residential land use and the third will represent
medium-to-high density residential land use.
ii. Each city having a population greater than 75,000 shall identify three
outfalls or conveyances where stormwater sampling could be conducted.
One outfall or conveyance shall represent commercial land use,the second
shall represent hi gh-density residential land use and the third will represent
industrial land use.
In 2010, City population is approximately 83,500. The City's monitoring plan
includes a proposed monitoring site for one conveyance representing primarily
commercial land use, a second proposed monitoring site representing primarily •
high-density residential land use, and a third proposed monitoring site
representing primarilylindustrial land use.
iii. Each county ha ling a population between 25,000 and 100,000 shall identify
two outfalls or conveyances where stormwater sampling could be
conducted. One 1 outfall shall represent commercial land use and the second
one will represent low-density residential land use.
iv. Each city having a population between 10,000 and 75,000 shall identify two
outfalls or conveyances where stormwater sampling could be conducted.
One outfall shall represent commercial land use and the second will
represent high-density residential land use.
v. Permittees shall select outfalls or conveyances based on known water
quality problem and/or targeted areas of interest for future monitoring. The
Permittee shall document:
• Why sites were selected;
• Possible site constraints for installation of and access to monitoring
equipment;
• • A brief description of the contributing drainage basin including size in
acreage, dominant land use, and other contributing land uses;
• Any water quality concerns in the receiving water of each selected outfall
or conveyance.
The SWU conducted a desktop screening assessment to prioritize receiving
waters based on the following criteria. Using information from this preliminary
screening and evaluation of receiving water concerns, the SWU identified a
number of candidate sites in the stormwater conveyance systems draining to
these receiving waters based on their representativeness for monitoring runoff
from the land use categories identified in the Phase II Municipal Stormwater
permit.
The SWU also conducted field visits to determine the feasibility of monitoring at
these candidate sites given site-specific characteristics related to monitoring
logistics such as the hydraulics in the conveyance system and access.
June 2010 Page 45
City of Renton Storm 2010 Storm Water Management Plan •
Information obtained from these field visits helped to narrow down the list of
monitoring sites to three monitoring sites selected for long-term monitoring.
The City's monitoring plan identifies possible constraints for installation of and
access to monitoring equipment. It also includes a description of the
contributing drainage basin and known water quality concerns in the receiving
water of each selected conveyance.
b. SWMP effectiveness monitoring
i. Each city,town and county shall prepare to conduct monitoring to determine
the effectiveness of the Permittee's SWMP at controlling stormwater-related
problems that are directly addressed by actions in the SWMP. This
component of the monitoring program shall be designed to answer the
following types of questions:
• How effective is a targeted action or narrow suite of actions?
• Is the SWMP achieving a targeted environmental outcome?
•
iii. No later than December 31, 2010, each city, town and county shall
identify at least two suitable questions and select sites where monitoring
will be conducted. This monitoring shall include, at a minimum, plans
for stormwater, sediment or receiving water monitoring of physical,
. chemical and/or biological characteristics. This monitoring may also
include data collection and analysis of other measures of program
effectiveness,problem identification and characterizing discharges for
planning purposes.
Two aspects of the stormwater program the City's monitoring plan will focus on
include the effectiveness of the new construction sediment and erosion control
inspection program and addressing high fecal coliform bacteria concentrations
••
in Johns Creek The following two questions were prepared to address each of
these issues:
1. How effective are the new construction inspection programs in reducing
turbidity levels from construction sites?
2. How effective is a targeted public education program for pet waste in
reducing fecal coliform bacteria concentrations in Johns Creek?
iii. For each question,the Permittee shall develop a monitoring.plan containing
the following elements:
• A statement of the question, an explanation of how and why the issue is
significant to the Permittee and a discussion of whether and how the
results-of the monitoring may be significant to other MS4s.
• A specific hypothesis about the issue or management actions that will be
tested.
• Specific parameters or attributes to be measured.
June 2010 _ Page 46

•
City of Renton Storm 2010 Storm Water Management Plan
• Expected modifications to management actions depending on the outcome
of hypothesis testing.
The City's monitoring plan addresses each of the above requirements.
2. Monitoring program reporting requirements
a. The fourth annual r4ort ort shall:
i. Describe the status of identification of sites for stormwater monitoring, if
required for the Permittee.
ii. Include a summary of proposed questions for the SWMP effectiveness
monitoring and describe the status of developing the monitoring plan,
including the proposed purpose, design, and methods.
The City's monitoring plan is included in the fourth annual report.
b. To comply with the equirements of all or part(s) of this section,permittees in a
single Urbanized Area or WRIA may choose to submit a collaborative report or
reports in lieu of separate reports.
The City Surface Wate, Utility is also evaluating the cost of implementing a local
monitoring program compared to the pay-in option for the Regional Monitoring
Plan (based on the Cit) 's population). The City is evaluating the costs, benefits,
and limitations of selecting the Local or the Regional Monitoring Plan option for
its monitoring program for the next permit cycle.
Record Keeping (S9.E.4)
4. Permittees shall includ I with the annual report submitted no later than March 31,
2011 information that at a minimum includes:
a. A summary of identified barriers to the use of low impact development(LID)
within the area covered by the permit and measures to address the barriers. Each
individual Permittee must complete this summary.
b. A report completed by an individual Permittee or in cooperation with multiple
Permittees describing, at a minimum:
i. LID practices that are currently available and that can reasonably be
implemented within this permit term.
ii. Potential or planned non-structural actions and LID techniques to prevent
stormwater impacts.
iii. Goals and metrics to identify, promote, and measure LID use.
iv. Potential or planned schedules for the Permittee(s)to require and implement
the non structural and LID techniques on a broader scale in the future.
The City Surface Water Utility prepared a report that identifies barriers to implementing
LID approaches in the.City of Renton. Barriers were identified through a literature
review and internal discussions with City Departments.

Introduction
Low impact development(LID) is an approach to stormwater management that seeks to
mimic the natural hydrologic functions of stormwater runoff prior to development
At its core,LID is a land use management philosophy that seeks to protect natural
resources,prevent pollution,minimize adverse environmental impacts, and improve
quality of life through green infrastructure and sustainable development In general,
LID techniques emphasize infiltration and evapotranspiration to remove pollutants and
attenuate flows from urban runoff. LID practicescan be applied to a variety of
development types,including residential,commercial,industrial, and recreational
development
This report identifies barriers to implementing LID approaches in the City of Renton.
Barriers were identified through a literature review and internal discussions with City
departments.

Introduction
Low impact development(LID) is an approach to stormwater management that seeks to
mimic the natural hydrologic functions of stormwater runoff prior to development.
At its core, LID is a land use management philosophy that seeks to protect natural
resources,prevent pollution,minimize adverse environmental impacts, and improve
quality of life through green infrastructure and sustainable development. In general,
LID techniques emphasize infiltration and evapotranspiration to remove pollutants and
attenuate flows from urban runoff. LID practices can be applied to a variety of
development types,including residential,commercial,industrial, and recreational
development.
This report identifies barriers to implementing LID approaches in the City of Renton.
Barriers were identified through a literature review and internal discussions with City
departments.

Phase II Stormwater Monitoring&Stormwater Management Program Effectiveness Monitoring.
Introduction
•
•
This monitoring plan summarizes site selection and the basic monitoring design for two
components of the long-term monitoring program specified in the National Pollutant Discharge
Elimination System (NPDES) Western Washington Phase II Municipal Stormwater permit • •
(Ecology 2009a): stormwater monitoring (S8.C.1.a) and Stormwater Management Program
Effectiveness (SWMP)monitoring(S8.C.1.b). The monitoring plan follows guidance provided
by the Washington State Department of Ecology(Ecology) in Monitoring and Reporting
Guidance—Phase II Municipal Stormwater Permits (Ecology 2010a). The plan is organized into
two main sections to present information related to the stormwater monitoring sites and SWMP
monitoring sites, respectively.

This section of the monitoring plan is divided into four main sections:
1. Background J ,
2. Preliminary Screening
3. Site Constraints
4. Drainage Basin Descriptions
Background
The City of Renton (City) has a population of 83,650 based on a 2009 estimate by the Office
of Financial Management(OFM 2010).The Phase II Municipal Stormwater permit(Ecology
2009a) states that cities with populations greater than 75,000 shall identify three outfalls or
conveyances for long-term stormwater monitoring.The monitoring sites should have drainage
areas that represent the following three land uses:
1. Commercial
2. High-density residential
3. Industrial
One monitoring site should be selected for each type of land use listed above. In the case
where basins have mixed land uses,the land use of highest single percentage can be
considered representative of the general land use in that basin.
•
Preliminary Screening
There are seven defined watersheds in the City:
1. Black River
2. Duwamish
3. Lake Washington East
4. Lake Washington West
5. Lower Cedar River
6. May Creek
7. Soos Creek
These watersheds are comprised of 22 subbasins.As a first step in identifying specific subbasins
for long-term monitoring,the City conducted a desktop screening assessment to prioritize
receiving waters based on the following criteria:

.
Site Constraints
Following the preliminary screening,the City identified a number of candidate sites in the
stormwater conveyance systems draining to the receiving waters identified in Table 1 based
on their representativeness for monitoring runoff from the land use categories identified in the
Phase II Municipal Stormwater permit.
•
Next,the City conducted field visits to determine the feasibility of monitoring at these candidate
sites given site-specific characteristics related to monitoring logistics such as the hydraulics in
the conveyance system and access. Information obtained from these field visits helped to narrow
down the list of monitoring sites to:the three monitoring sites selected for long-term monitoring;
these sites are described in Table 2 with any relevant monitoring constraints.
Drainage Basin Descriptions
The approximate drainage basin size, dominant land use, and other contributing land uses
were determined for each of the three selected stormwater monitoring sites using Geographic
Information System (GIS) data and'are summarized in Table 2.The approximate drainage basin

boundaries are shown in Figures 1,2, and 3 for the residential, commercial,and industrial sites,
respectively. Prior tomonitoring,ifield verification is recommended for final drainage basin
delineation.
Since the land use with the dominant land use in each drainage basin matches the land use
categories specified in the Phase IiI Municipal Stormwater permit, the three monitoring sites meet
the requirements for site selection.The sites selected for residential and commercial monitoring
are both part of the Lake Washington East drainage basin.The site selected for industrial
stormwater monitoring is part of the Black River drainage basin.Both Lake Washington(near
• the outlet of the Lake Washington East drainage basin) and the Black River are on the 303(d) list
for fecal coliform bacteria(Table 1),.
The City will refer to the Standard Operating Procedure for Automatic Sampling for Stormwater
Monitoring(Ecology 2009b)when developing the quality assurance project plan(QAPP) for
conducting this monitoring.

Phase 11 Stormwater Monitoring& Stormwater Management Program Effectiveness Monitoring
Stormwater Management Program Effectiveness
Monitoring
• The City is also required to develop two SWMP effectiveness questions to evaluate and improve
the effectiveness of their stormwater program by collecting and applying the results of water
quality sampling.Based on discussions with the City,the two aspects of the stormwater program
that the City would like to focus on include the effectiveness of the new construction sediment
and erosion control inspection program and public outreach efforts to address high fecal coliform
bacteria concentrations in Johns Creek.The following two questions were prepared to address
each of these issues:
1. How effective are the new construction inspection programs in reducing
turbidity levels from construction sites?
2. How effective is a targeted public education program for pet waste in
reducing fecal coliform bacteria concentrations in Johns Creek?
This section of the monitoring plan is divided into two subsections to provide more detailed
information on each of these questions:
1. Monitoring plan for SWMP Question#1
2. Monitoring plan for SWMP Question#2
•
Monitoring Plan for SWMP Question #1 •
This section discusses the purpose and design of the monitoring plan for the following'question
• and hypothesis related to the City's new construction inspection programs: •
•
Question#1: How effective are the new construction inspection programs in
reducing turbidity levels from construction sites?
Hypothesis: The new construction inspection programs will result in a significant
reduction in turbidity levels downstream of active construction sites compared to
baseline water quality data from construction sites that are not subject to similar
inspection programs.
Purpose •
The purpose of the new construction inspection programs is to ensure compliance with sections
S5.C.4.b and S5.C.4.c of the Phase II Municipal Stormwater permit. The City is interested in
determining if the construction inspection programs have an impact on the turbidity levels

observed downstream of active construction sites.The City will use this information to justify
continued construction inspections on the same schedule or to increase or decrease the number of
construction inspections to ensurethat turbidity criteria are met.This issue is important to the
City since there are a significant number of single family residential construction projects in the
City and they would like to know if their construction inspections are benefitting the downstream
water quality. Based on discussions at the January 2011 NPDES permit coordinators forum,
construction site monitoring is a topic of interest to many Phase II jurisdictions,thus the results
from this monitoring will be important on a regional scale. The results from this monitoring
would be shared with other Phase I and Phase II jurisdictions to benefit their construction
inspection programs.
Design •
The monitoring design to address this particular monitoring question will involve selecting
monitoring sites from active construction sites in the City. Stormwater samples would be
• collected using grab sampling techniques upstream (if feasible) and downstream of the •
construction sites and analyzed for turbidity in the field using a turbidimeter. The City will refer
to the Standard Operating Procedure for Collecting Grab Samples from Stormwater Discharges
(Ecology 2009c) when developing the QAPP for conducting this monitoring. The data collected
from these construction sites will be compared to baseline water quality data from construction
sites that are not subject to similar inspection programs that are compiled in the Interim Report:
Stormwater Quality Survey of Western Washington Construction Sites(Ecology 2004) and/or
data collected from construction sites as part of the Construction NPDES Stormwater General
Permit(Ecology 2010b). Since proposed locations will vary depending on the active construction
sites at the time, a map or diagram showing the monitoring locations has not been provided with
this monitoring plan.
The anticipated schedule for the construction site SWMP effectiveness monitoring will involve
selecting a subset(5 to.10 percent) of active construction monitoring sites at the beginning of
the wet season (September or October).At least four monitoring sites would be sampled during
five storm events to ensure a robust dataset for further analysis.Additional monitoring sites and
storm events can be added as needed to build a more robust dataset. The monitored storm events
should be targeted to meet the following storm event guidelines (Ecology 2008): -
■ Minimum storm depth: 0.15 inches
■ Antecedent dry-period: 6 hours with less than 0.04 inches of rain
• Minimum,storm duration: 1 hour
One sample should be collected prior to clearing and construction at the monitoring site, a
second sample should be collected prior to the first construction inspection, and a third sample
should be collected following the first construction inspection.The remaining two samples
should be collected from each monitoring site during the remainder of the wet season.The data
obtained from this sampling would be compared to baseline water quality data compiled in the
Interim Report:Stormwater Quality Survey of .Western Washington Construction Sites(Ecology
2004)and/or data collected from construction sites as part of the Construction NPDES

Monitoring Plan,for swim. Question #2
This section discusses the purpose and design of the monitoring plan for the following question
and hypothesis related to a targeted public education program for pet waste:
Question#2: How effective is a targeted public education program for pet waste
in reducing fecal coliform bacteria concentrations in Johns Creek?
Hypothesis: The targeted public education program for pet waste will have a
minimal positive effect on reducing fecal coliform bacteria concentrations in , .
Johns Creek.
Purpose
The purpose of the targeted public education is to provide education and outreach to the general
public regarding proper disposal of pet waste and will be a component of the City's education
and outreach program (S5.C.1.a.i orthe Phase II Municipal Stormwater permit).The City is
interested in determining if pet waste is a significant contributor to fecal coliform concentrations
measured in Lake Washington near the swimming beach at Gene Coulon Memorial Beach Park
and the outlet from Johns Creek. Pets are currently not allowed in Gene Coulon Memorial
Beach Park, but are found in other portions of the Johns Creek watershed. The City will use
this information to determine if the fecal coliform concentrations are originating from the
primarily residential basin in the upper watershed or from another source (i.e., seagulls, illicit
discharges). Where it can be determined that the fecal coliform bacteria contamination is
primarily originating from pet waste.the City will implement targeted education programs in
these areas in an effort to reduce the contamination. This issue is important to the City because
there is a 303(d) listing for Lake Washington near the outlet to Johns Creek, although a total
maximum daily load (TMDL) has not yet been assigned.Although this monitoring plan is
targeted towards a specific drainage basin and water quality issue in the City,the monitoring
results will be applicable on a regional scale to.other cities and counties that are faced with fecal
coliform bacteria TMDLs and would like to implement a targeted public education campaign in
their watersheds.The results from this monitoring would be shared with other Phase I and
Phase II jurisdictions to benefit their public education programs.
•
Design
The monitoring site to address this particular monitoring question will be the same residential •
site(Edmonds and NE 7th Street)used for the stormwater monitoring summarized previously
(Figure 1). Stormwater samples would be collected using grab sampling techniques and
submitted to a.qualified laboratory to be analyzed for fecal coliform bacteria.The City will refer

Phase ll Stormwater Monitoring&Stormwater Management Program Effectiveness Monitoring
to the Standard Operating Procedure for Collecting Grab Samples from Stormwater Discharges
(Ecology 2009c) when developing the QAPP for conducting this monitoring.
Baseline water quality data will be collected before the targeted public education campaign
begins. Monitoring data will also be compared to historical data collected by King County as part
of the King County Swimming Beach Monitoring Program.
The anticipated schedule for the fecal coliform SWMP effectiveness monitoring will involve
monthly monitoring for 12 months prior to initiating the targeted public education campaign and
12 months after the campaign.The monitored storm events should be targeted to meet the
following storm event guidelines (Ecology 2008):
• Minimum storm depth: 0.15 inches
• Antecedent dry-period: 6 hours with less.than 0.04 inches of rain
• • Minimum storm duration: 1 hour •
If significant rainfall does not occur during the summer months, a grab sample can still be
collected if flow is present in the catch basin. If no flow is present,that observation will be
recorded on a field form and no sample will be collected. Fecal coliform bacteria concentrations
from this monitoring will be tracked over time to determine if there is a significant decreasing
trend in the data that may be related to the targeted education program.
