permits for multiple activities that could impact water quality. These include but are not limited to:
Industrial Activities
Operating an MS4
Construction Activities
Utility operates its stormwater program under its NPDES Permit. The most recent permit was issued on
July 1, 2019 and became effective on August 1, 2019. The City has been operating under the NPDES
Permit since 2007. Continued City NPDES Permit coverage requires compliance with special and general
conditions outlined in the 2019 permit. These include the continuation of conditions familiar to Renton
from the 2013 Permit and new conditions that must be implemented by the prescribed permit schedule. A summary of Renton’s activities to meet permit compliance is available in the City’s current
Stormwater Management Program Plan. New regulatory requirements and resource needs are
described in a regulatory memorandum (Appendix D) and in Section 5.
Key changes, from the previous permit to new permit beginning in August 2019, are described below. A
summary of resource needs and deadlines for these NPDES changes is provided in Section 5, Table 5‐1.
4.4.8.1 LONG‐RANGE PLANNING
The new permit requires a review of how stormwater management needs and protection/improvement
of receiving water health are informing long‐term plans.
Add section here for low impact development to review and document administrative and
regulatory barriers annually.
4.4.8.2 WATERSHED PLANNING
The new permit requires the City to evaluate watershed conditions and prioritize its watersheds based
on receiving water conditions and ability to affect change with stormwater management actions. A
stormwater management action plan must be developed for a high priority catchment that outlines strategies and projects to improve watershed conditions.
4.4.8.3 MS4 MAPPING
Continue documenting conditions in MS4, collect and update outfall size and material data, and
complete mapping of all known connections from privately owned stormwater systems.

REGULATORY REQUIREMENTS AND CITY POLICIES
O SBORN C ONSULTING, I NC.
B ELLEVUE • S EATTLE • S POKANE 4‐10
Section 404 permit. The federal agency cannot issue its permit until the certification is approved,
conditioned, or waived by the state. If the state denies a certification, an individual Section 401
certification is required for activities covered by a nationwide permit (ORIA, 2020).
4.4.8 SECTION 402 – NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM
Section 402 of the CWA states that pollutants may not be discharged directly to surface waters unless
this is done under a NPDES permit. In Washington, authority to issue permits and oversee compliance
has been delegated to Ecology by the EPA. Ecology asserts requirements and a schedule for compliance.
The compliance schedule is never longer than the term of the permit. Permits are required to be
renewed at least every five years, and Ecology is responsible for writing new permits.
The NPDES program, as it relates to precipitation‐induced runoff (considered a point source), provides
permits for multiple activities that could impact water quality. These include but are not limited to:
Industrial Activities
Operating an MS4
Construction Activities
