Project Summary:
The applicant is requesting Environmental (SEPA) Review for the non-project item:
Stormwater Pollution Source Control Program. Staff propose to amend Surface Water
(Drainage) Standards in chapter 4-6-030 and defintions in 4-6-100 to add requirements
to implement source control best management practices at public and pr ivate
properties with potential to release pollutants into the storm system.

Determination of Non-Significance (DNS).
PART ONE: PROJECT DESCRIPTION / BACKGROUND
The current Western Washington Phase II Municipal Stormwater Permit (Permit) which became effective in August
2019 requires Renton to implement a new Stormwater Pollution Source Control (SPSC) program for existing
developments. Source control is a practice that relies on preventative measures to stop pollutants before they enter
the city’s storm system and subsequently end up in receiving waters. Source Control aims to address accumulation of
non-point source pollutants such as fertilizers, paint, oil and grease, and wash water that originate from daily
business/site activities, spill incidents, improper disposal, or other indirect sources. As such, the SPSC program will
reduce pollutants in surface water runoff from public and private commercial and industrial land uses that discharge
into the city’s stormwater system. The implementation process of this new program is required to meet the following
timeline:
A. Source Control Ordinance: By August 1, 2022, the city must adopt and make effective an ordinance to require
the application of SPSC best management practices (BMPs) from pollutant-generating sources associated with
existing land uses and activities. To meet this requirement, the Surface Water Engineering Section prepared an
ordinance that defines the purpose and applicability of the Source Control Program as well as address es the right
of entry for inspections, establishes a progressive enforcement process, and describes any applicable fines and
penalties for pollutant discharges not resolved through education and outreach. This ordinance introduces
multiple code amendment to Development Regulations in Title IV, specifically to chapter 4-6-030 (Surface Water
Standards) and 4-6-100 (Definitions). A public hearing on this program and ordinance was conducted on June 15,
2022.

B. Source Control Inventory: By August 1, 2022, the city must establish an inventory of public and private
properties institutional, commercial, and industrial sites with potential to release p ollutants into the stormwater
system.
C. Implementation: By January 1, 2023, the city must implement an on -going inspection program and progressive
enforcement policy.
The Surface Water Utility Engineering Section will administer the SPSC program. Assign ed staff will conduct and direct
on-site source control inspections at public and private institutional, commercial, and industrial properties with
pollutant generating activities. During investigations and/or inspections, assigned staff will identify, record, and report
all defects/deficiencies and necessary maintenance in an adequate database system, to bring pollutant generating
sources into compliance with the Renton Municipal Code. Correction letters will be sent to property owners to notify
them of repairs, maintenance, or adjustments necessary to bring their business or property into compliance.
This program will primarily rely on technical assistance, education and outreach to businesses owners and operators
to prevent pollutants from entering the s tormwater system. However, where necessary, this program will require
operational or structural source control best management practices, or treatment BMPs/facilities to prevent pollution
from entering the stormwater system.
The following are examples of source control BMPs that assigned staff may request from businesses:
• Storing wastes in leak-proof containers with solid lids (e.g., dumpsters and trash compactors). No rainwater
should be able to enter the container and no fluids should be leaking out.
• Keeping all waste receptacles (e.g., dumpsters, garbage cans, used cooking oil/grease containers) closed
except when adding waste.
• Replacing or repairing leaking outdoor waste containers.
• Making sure all outside materials that have the potential to leach or spill to the stormwater drainage system
are covered, contained, or moved to an indoor location.
• Training employees to keep outdoor storage areas clean.
PART TWO: ENVIRONMENTAL REVIEW
In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project
impacts that are not adequately addressed under existing development standards and environmental regulations.
A. Environmental Threshold Recommendation
Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials:
Issue a DNS with a 14-day Appeal Period.
B. Mitigation Measures
None
C. Exhibits
None
D. Environmental Impacts
There are no environmental impacts that are anticipated to occur in conjunction with the proposal

E. Comments of Reviewing Departments
The proposal has been circulated to City Departments and Division Reviewers. Where applicable, their
comments have been incorporated into the text of this report and/or “Advisory Notes to Applicant.”
✓ Copies of all Review Comments are contained in the Official File and may be attached to this report.
The Environmental Determination decision will become final if the decision is not appealed within the 14 -day
appeal period (RCW 43.21.C.075(3); WAC 197-11-680).
Environmental Determination Appeal Process: Appeals of the environmental determination must be filed in writing
on or before 5:00 PM on July 11, 2022. Due to the ongoing state of emergency enacted by Governor’s Proclamation
20-28.14, (and as amended), the City Clerk’s Office is working remotely. For that reason, appeals must be submitted
electronically to the City Clerk at cityclerk@rentonwa.gov or delivered to City Hall 1st floor Lobby Hub Monday
through Friday. The appeal fee, normally due at the time an appeal is submitted, will be collected at a future date if
your appeal is submitted electronically. Appeals to the Hearing Examiner are governed by RMC 4-8-110 and additional
information regarding the appeal process may be obtained from the City Clerk’s Office, cityclerk@rentonwa.gov.
