INTRODUCTION 1.1 Overview This document presents the City of Auburn’s Stormwater Management Program (SWMP). Preparation and maintenance of this SWMP Plan is required by the Washington State Department of Ecology (Ecology) as a condition of the Western Washington Phase II Municipal Stormwater Permit (the Phase II Permit). The Phase II permit covers discharges from regulated small municipal separate storm sewer systems (MS4s). The SWMP Plan is intended to inform the public of the planned SWMP activities for the upcoming year. The permit to discharge stormwater is designed to reduce the discharge of pollutants, protect water quality, 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 City’s Stormwater Management Program. 1.2 Regulatory Background The National Pollutant Discharge Elimination 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 minimum 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 II Municipal Stormwater Permit is available on Ecology’s website at http://www.ecy.wa.gov/programs/wq/stormwater/municipal/phaseIIww/wwphiipermit.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 “maximum extent practicable” (MEP) through application of Permit-specified “best management practices” (BMPs). The BMPs specified in the Permit are collectively referred to as the Stormwater Management Program (SWMP) and grouped under the following Program components:  Public Education and Outreach  Public Involvement and Participation  Illicit Discharge Detection and Elimination  Controlling Runoff from New Development, Redevelopment, and Construction Sites 1: Introduction City of Auburn 2016 SWMP Plan 2 C:\Users\asherwi\Desktop\2016 SWMP Plan Final Draft 20160111.docx  Municipal Operations and Maintenance In addition to the SWMP components the Permit contains special conditions covering:  Compliance with Total Maximum Daily Load requirements  Monitoring and Assessment  Reporting Requirements The Permit issued by Ecology became effective on August 1, 2013, was modified January 16, 2014 and expires on July 31, 2018. The Permit requires the City to submit an annual report no later than March 31st of each year beginning in 2015, on progress in SWMP implementation. The Permit also requires submittal of a SWMP Plan which describes proposed SWMP activities for the current calendar year. The SWMP Plan is to be updated annually and be included in the submittal of the previous year’s annual report. 1.3 City of Auburn Regulated Area The Western Washington Phase II 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 Whatcom, Skagit, Snohomish, King, Pierce, Lewis and Skamania counties). For cities, the Permit requirements extend to those areas of each City that drain to MS4s. Most of Auburn drains to MS4s that ultimately discharge into the Green River, the White River, or Mill Creek. In addition, some portions of the City drain to public infiltration facilities where the stormwater soaks into the ground. 1.4 SWMP Implementation Responsibilities The Utilities Engineering Division in the Community Development and 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 2016 SWMP implementation are Maintenance and Operations (M&O), Human Resources (HR), Development Engineering, Permit Center, Innovation and Technology (IT), and Parks. 1.5 Document Organization The contents of this document are based upon Permit requirements and Ecology’s “Guidance for City and County Annual Reports for Western Washington, Phase II Municipal Stormwater General Permits.” The program components of this SWMP are organized as listed in the Permit:  Section 2.0 addresses administering the City’s Stormwater Management Program.  Section 3.0 addresses public education and outreach.  Section 4.0 addresses public involvement and participation.  Section 5.0 addresses illicit discharge detection and elimination.  Section 6.0 addresses controlling runoff from new development, redevelopment, and construction sites.  Section 7.0 addresses municipal operations and maintenance.  Section 8.0 addresses compliance with TMDL requirements.  Section 9.0 addresses monitoring. Each section includes a summary of the relevant Permit requirements and a table showing the planned activities for 2016. This document also includes acronyms and definitions in Appendix A for easy reference. 3 C:\Users\asherwi\Desktop\2016 SWMP Plan Final Draft 20160111.docx CITY OF AUBURN 2016 STORMWATER MANAGEMENT PROGRAM PLAN 2. STORMWATER MANAGEMENT PROGRAM ADMINISTRATION This section of the SWMP describes Permit requirements related to overall Stormwater Management Program administration, and planned compliance activities for 2016. 2.1 Permit Requirements The Permit (Section S5.A) requires the City to fulfill the following actions during the 5-year Permit cycle:  Develop and implement a Stormwater Management Program (SWMP) and prepare written documentation (SWMP Plan) for submittal to Ecology by March 31 of each year. The purpose of the SWMP is to reduce the discharge of pollutants from the municipal stormwater system to the maximum extent practicable and thereby protect water quality. The SWMP Plan is intended to inform the public of the planned SWMP activities for the upcoming calendar year, including any actions to meet the requirements of S7 Compliance with Total Maximum Daily Load Requirements, and S8 Monitoring.  Implement a program for gathering, tracking, maintaining, and using information to evaluate SWMP development, implementation and permit compliance and to set priorities.  Coordinate with other permittees 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. 2.2 Planned 2016 Compliance Activities Auburn has positioned itself to maintain compliance.

COMPLIANCE WITH TOTAL MAXIMUM DAILY LOAD REQUIREMENTS The federal Clean Water Act requires that Ecology establish “Total Maximum Daily Loads” (TMDL) for rivers, streams, lakes, and marine waters that don’t meet water quality standards. A TMDL is a calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards. After the TMDL has been calculated for a given water body, Ecology determines 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. Stormwater discharges covered under this Permit are required to implement actions necessary to achieve the pollutant reductions called for in applicable TMDLs. Applicable TMDLs 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 TMDL program is available on Ecology’s website at www.ecy.wa.gov/programs/wq/tmdl. In accordance with Permit condition S7 Compliance with Total Maximum Daily Load Requirements the City must comply with the following TMDL.
