This document presents the City of Auburn’s Stormwater Management Program (SWMP). Preparation and maintenance of this SWMP 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). Based on criteria outlined in the Phase II Permit, Ecology considers the City of Auburn to be an operator of a small MS4, and therefore required to obtain permit
coverage. Each municipality's permit for discharging 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). Municipalities with
a population of over 100,000 (as of the 1990 census) have been designated as Phase I communities and must comply with Ecology’s Phase I NPDES Municipal Stormwater Permit. With Auburn’s
1990 census falling below the 100,000 threshold, the City must comply with the Phase II Municipal Stormwater Permit. About 100 other municipalities in Washington must now comply with
the Phase II Permit, along with Auburn, 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) 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 Illicit Discharge Detection
and Elimination
1: Introduction City of Auburn 2011 SWMP 1-2 H:\PUB_WRKS\Utilities\Storm\NPDES II\Administration\SWMPs\2011 SWMP\2011 Auburn SWMP 201100204.doc Controlling Runoff from Development, Redevelopment,
and Construction Sites Pollution Prevention and Municipal Operation and Maintenance Monitoring The Permit issued by Ecology became effective on February 16, 2007, was modified on June
17, 2009 and expires on February 15, 2012. The Permit requires the City to report annually (March 31st of each year) on progress in SWMP implementation for the previous year. The Permit
also requires submittal of documentation that describes proposed SWMP activities for the coming year. This document contains the City’s proposed activities for 2011. Implementation of
various Permit conditions is staggered throughout the five-year Permit term from February 16, 2007 through February 15, 2012. The Permit will be revised and reissued at the end of this
period. 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 regional infiltration basins. 1.4 Total Maximum Daily Load (TMDL) Compliance 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. The Clean Water Act requires that TMDL requirements must be included in the NPDES permits
for dischargers into the 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 date the permittee’s
application was received by Ecology. Information on Ecology’s TMDL program is available on Ecology’s website at www.ecy.wa.gov/programs/wq/tmdl. The current permit does not contain any
TMDL requirements for the City of Auburn. However, Ecology has identified several water bodies that do not appear to meet the water quality standards. If Ecology establishes TMDLs for
one or more of these water bodies prior to 2012, the next version of the Permit may contain additional requirements specified in the TMDL. 1.5 SWMP Implementation Responsibilities The
Utilities Engineering 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 2011 SWMP implementation include Maintenance and Operations (M&O), Human Resources
(HR), Development Engineering, Permit Center, Information services (IS), and Parks.

PROGRAM ADMINI STRAT ION This section of the SWMP describes Permit requirements related to overall Stormwater Management Program administration, including descriptions of the City’s
current and planned compliance activities for 2011. 2.1 Permit Requirements The Permit (Section S5.A) requires the City to: Develop and implement a Stormwater Management Program and
prepare written documentation for submittal to Ecology on March 31, 2008, and update the SWMP annually thereafter. 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. Submit annual compliance reports (for the previous calendar year) to Ecology on March
31, beginning in 2008 that summarize the status of implementation and provide information from assessment and evaluation procedures collected during the reporting period. Coordinate
with other permittees on stormwater related policies programs, and projects within adjacent or shared areas. 2.2 Current Compliance Activities The City has activities and programs that
meet many of the Permit requirements. The current compliance activities associated with the Permit include: The City is on track to comply with Ecology requirements for submittal of
SWMP documentation by March 31, 2011. The Utilities Engineering Division is currently leading the development of the future planned activities with input and support from several other
departments. The City created an NPDES implementation management group. The City set up the systems for tracking training. Training attendance is recorded and kept on file with Human
Resources. The City has defined its strategy for cost tracking. Cost tracking is managed by staff recording time spent on Permit elements on their timecards using project coding numbers.
Reports can be generated by the Finance Department to determine annual costs by element. The City has defined and implemented a strategy for managing SOPs. SOPs are available for staff
use on the City’s Intranet. The City is participating in a regional education and outreach consortium. Staff has ensured that the City’s education and outreach program will work in concert
with regional efforts such as the Puget Sound Starts Here campaign. The City is on track to comply with Ecology’s requirements for submittal of the fourth Annual Report by March 31,
2011.

redevelopment, and construction site activities. The program must apply to both private and public projects, including roads, and address all construction/development-associated pollutant
sources. Adopt regulations (codes and standards) and implement plan review, inspection, and escalating enforcement SOPs necessary to implement the program in accordance with Permit conditions,
including the minimum technical requirements in Appendix 1 of the Permit. Develop provisions (plan review, inspection, and enforcement) and SOPs to allow non-structural preventive actions
and source reduction approaches such as Low Impact Development techniques to minimize the creation of impervious surfaces and the disturbance of native soils and vegetation. Adopt regulations
(codes and standards) and processes to verify adequate long-term operations and maintenance of new post-construction permanent stormwater facilities and BMPs in accordance with Permit
conditions, including an annual inspection frequency and/or approved alternative inspection frequency and maintenance standards for private drainage systems as protective as those in
Chapter IV of the 2005 Ecology Stormwater Management Manual for Western Washington. Provide copies of the Notice of Intent (NOI) for construction or industrial activities to representatives
of the proposed new development and redevelopment. Provide training to staff on the new codes, standards, and SOPs and create public education and outreach materials. Develop and define
a process to record and maintain all inspections and enforcement actions by staff. Summarize annual activities for the “Controlling Runoff” component of the Annual Compliance Report;
identify any updates to the SWMP.

describes the Permit requirements related to water quality monitoring, including descriptions of the City’s current and planned compliance activities for 2011. 8.1 Permit Requirements
The Permit (Section S8) does not require municipalities to conduct water quality sampling or other testing during this permit term, with the following exceptions: Sampling or testing
required for characterizing illicit discharges pursuant to the SWMP’s IDDE conditions. Water quality monitoring required for compliance with Total Maximum Daily Load (TMDL) conditions
(water quality clean up plans). The current Permit does not require that Auburn perform TMDL-related monitoring because Ecology has not established TMDLs for water bodies that receive
stormwater runoff from the City. Preparing future comprehensive, long-term water quality monitoring monitoring plan including two components: 1) stormwater monitoring and 2) targeted
Stormwater Management Program effectiveness monitoring. By the 4th Annual Compliance Report (March 31, 2011), Auburn is required to identify two outfalls or conveyances where permanent
stormwater sampling stations can be installed and operated for future monitoring. The City is also required to develop plans to monitor stormwater, sediment, and receiving water for
physical, chemical, and/or biological characteristics. One outfall must represent high-density residential land use, and the other commercial land use. To monitor SWMP effectiveness,
the City will need to identify two suitable Program questions and sites where targeted Program effectiveness monitoring can be conducted and develop a monitoring plan for these questions
and sites. The proposed effectiveness monitoring is required to answer the following types of questions: • How effective is a specific targeted action or a narrow suite of actions? •
Is the Stormwater Management Program achieving a targeted environmental outcome? In addition, the City is required to provide the following monitoring and/or assessment data in each
annual report: A description of any stormwater monitoring or studies conducted by the City during the reporting period. If stormwater monitoring was conducted on behalf of the City,
or if studies or investigations conducted by other entities were reported to the City, a brief description of the type of information gathered or received shall be included in the annual
report. An assessment of the appropriateness of the best management practices identified by the City 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.
