STORMWATER MANAGEMENT PROGRAM PLAN
1 . INTRODUCTION
1.1 Overview
This document presents the City of Auburn's Stormwater management Program (SWNIP). Preparation and
maintenance of this SWIMP Plan is required by the Washington State Department of Ecology(Ecology) as a
condition of the Western Washington Phase Il Municipal Stormwater Permit(the Phase II Permit). The
Phase II permit covers discharges from regulated small municipal separate storm sewer systems (MS4s). The
SWIAP Plan is intended to inform the public of the planned SWNIP activities for the upcoming year.
The permit to discharge stormwater is designed to reduce the discharge of pollutants,protect water qualiiv,
and meet the requirements of the federal Clean Water Act.
Appendix A includes acronyms and definitions from the Permit to help the reader understand the Ciu.'s
Stomnater Management Program.
1.2 Regulatory Background
The National Pollutant Discharge 131unination System (NPDES) permit program is a requirement of the
federal Clean Water Act,which is intended to protect and restore waters for"fishable,swimmable" uses. The
federal Environmental Protection Agency(EPA) has delegated permit authority to state environmental
agencies,and these agencies can set permit conditions in accordance with and in addition to the mumnum
federal requirements. In Washington, the NPDES-delegated permit authority is the Washington State
Department of Ecology (Ecology).
In Washington, municipalities with a population of over 100,000 are designated as Phase I communities and
must comply with Ecology's Phase I NPDES municipal Stormwater Permit Auburn's population is below
the 100,000 threshold, so the City must comply with the Phase II municipal Stormwater Permit. About 100
other municipalities in Washington must also comply with the Phase II Permit,as operators of small
municipal separate storm sewer systems (MS4s). Ecology's Phase 11 municipal Stormwater Pertnit is available
on Ecology's wcbsite at
httn:///Nynvw.ech.wa.gov/proeranhs/wq/stormwater/municipal/phaseI I«�v/xywphiipernut.html
The Permit allows- municipalities to discharge stormwater runoff from municipal drainage systems into the
state's water bodies (e.g., streams, rivers, lakes,wetlands,and aquifers) as long as municipalities implement
programs to protect water quality by reducing the discharge of"non-point source" pollutants to the
11 maximum extent practicable" (NII3P) through application of Permit-specified "best management practices"
(BINIPs). The 13NIPs specified in the Perm t are collectively referred to as the Stormwater Management
Program (SWIM P) and grouped under the following Program components:
• Public Education and Outreach
• Public Involvement and Participation
• Illicit Discharge Detection and Flimination
• Controlling Runoff from New Development,Redevelopment, and Construction Sites

1 Introduction City of Auburn 2014 SWMP Plan
IN Municipal Operations and Maintenance
In addition to the SWMP components the Permit contains special conditions covering
• Compliance with Total Maximum Daily load regwrements
• Monitoring and Assessment
• Reporting Requirements
The Permit issued by Ecology became effective on August 1,2013 and expires on July 31, 2018. The Permit
requires the City to subimt an annual report no later than March 3 h" of each year beginning in 2015,on
progress in SWMP implementation. The Pernut also requires submittal of a S\C AIP Plan which describes
proposed SWMP activities for the current calendar year. The SWMP Plan is to be updated annually and be
included in the subnuttal of the previous year's amoral report
1.3 City of Auburn Regulated Area
The Western Washington Phase 1I Permit applies to operators of regulated small MS4s that discharge
stormwater to waters of Washington State located west of the crest of the Cascade Range (west of the eastern
boundaries of Whatconn,Skagit,Snohomish,King,Pierce, Lewis and Skamania counties) For cities, the
Permit requirements extend to those areas of each City that drain to N4S4s Most of Auburn drains to NIS4s
that ultimately discharge into the Green River, the Wbite River,or Mill Creck In addition, some portions of
the City dratii to regional infiltration basins
1.4 SWMP Implementation Responsibilities
The Utilities F'rigineering Division in the Public Works Department coordinates the overall administration of
efforts to comply with Permit requirements. The work plan tables in each Chapter provide the lead
departments for the associated task. Other major departments/divisions included in the 2014 SWAP
mnplcmentation are \huntenance and Operations (M&O),Human Resources (14R),Development
Engineering, Permit Center, Innovation and Technology (11), and Parks.
1.5 Document Organization
The contents of this document are based upon Permit requirements and Ecology's "Guidance for Citv and
County Amoral Reports for Western Washington,Phase ii Municipal Stormwater General Pernnits."The
program components of this SWMP are organized as listed in the Permit:
• Section 2.0 addresses administering the City's Stornnvater Management Program.
• Section 3.0 addresses public education and outreach.
• Section 4.0 addresses public involvement and participation.
• Section 5.0 addresses dhcit discharge detection and clam nation.
• Section 6.0 addresses controlling runoff from new development,redevelopment,and constriction
sites.
• Section 7.0 addresses municipal operations and maintenance.
• Section 8.0 addresses compliance with TDIDL requirements.
• Section 9.0 addresses monitoring.
Each section includes a summary of the relevant Permit reguirenneutS and a table showing the planned
activities for 2014. This document also includes acronyms and definitions in Appendix A for easy reference

SWMP is to reduce the discharge of pollutants from the municipal stormwater system to the maximum
extent practicable and tlicreby protect water quality The SWIVP Plan is intended to inform the public
of the planned SWMP activities for the upcoming calendar year, and any actions to meet the
requirements of S7 Compliance with Total Maximum Dadv Load Requirements, and S8 Monitoring.
• Implement a program for gathering, tracking,maintaining, and using information to evaluate SVrT\IP
development,implementation and permit compliance and to set priorities
• Coordinate with other perinittees on stormwater related policies programs,and projects within
adjacent or shared areas
• Coordinate between City departments to eliminate barriers to compliance with the terms of the permit.

STORMWATER MANAGEMENT PROGRAM PLAN
8 . COMPLIANCE WITH TOTAL MAXIMUM DAILY LOAD
REQUIREMENTS
The federal Clean Water Act requires that Ecology establish "Total Maximum Daily Loads" (TNIDL) for
rivers, streams,lakes,and marine waters that don't meet water quality standards. A 'rNMI,is a calculation of
the maximum amount of a pollutant that a water bode can receive and still meet water quality standards.
After the TNIDL has been calculated for a given water bode, Ecology deteinunes how much each source
must reduce its discharges of the pollutant in order bring the water body back into compliance with the water
quality standards. TMDL requirements are included in the stormwater NPDES permits for discharges into
affected water bodies.
Stormxvater discharges covered under this Permit are required to implement actions necessary to achieve the
pollutant reductions called for inapplicable TNIDI.s Applicable'1'NIDLs are those approved by the EPA
before the issuance date of the Permit or which have been approved by the EPA prior to the issue date of the
Permit or the date Ecology issues coverage under the Permit,whichever is later. Information on Ecology's
TNIDL program is available on Ecology's website at wanv.ecy.iya.gov/programs/wq/tmdl.
In accordance with Permit condition S7 Compliance with Total Maximum Daily Load Requirements the City
