STORMWATER MANAGEMENTPROGRAM
1. INTRODUCTION
9.1 Overview
This document presents the City of Aubum's Stormwater Management Program (SV/MP). Pteparation and maintenance of this SWMP is xequired by the Washington State Depaztrnent of Ecology (Ecology) as a
condition of the Western Washington Phase II Municipal Stormwater Permit (the Phase II Permit). T'he
Phase II pemtit covexs discharges from iegulated small muniupal separate storm sewez systems (MS4s).
Based on criteria outiined in [he Phase II Permit, Ecology considers the City of iluburn to be an opecatoz of
a small MS4, and thereEore xequired to obtain pernut mverage.
~
Each muriidpality's pemut foz dischazging stormwater is designed ro reduce the dischaxge of pollucants,
pcotect warer quality, and meet the xequicements of the fede=al Clean Water Act .
Appendix A indudes acsonyms and defuutions from the Pexmit to help the reades undecstand the City's
Stormwater Management Progxazn.
9.2 Regulatory Baclcground
The Nadonal Pollutant Dischazge Elimination System (NPDES) permit pxogram is a requirement of the
fedecaL. Clean Warer Act, which is intended to piotect and restore vratexs fox "fishable, swimmable" uses. The
federaL Enviconmental Pxotection Agency (EPA) has delegated pextnit authoriry to state enviconmental
agencies, and these agencies can set pesmit condidons in accordance with and in addirion to the minimum
federal requixements. In Washingtoq the NPDES-delegated permit auchoriry is che Washington State
Depaztment of Ecology (Ecology). Municipalities with a populadon oE over 100,000 (as of the 1990 census) have been designated as Phase I
communides and must comply with Emlogy's Phase I NPDES Municipal Stormwater Permit. With Auburn's
1990 census faLling below the 100,000 thzeshold, the City must comply with the Phase II Municipal
Stormwater Pemut. About 100 othes municipalides in Washington must now comply with the Phase II
PeLmit, along with Aubuzn, as operators of small municipal separate storm sewer systems (MS4s). Ecolog}'s
Phase II Municipal Stormwater Permit is available on Ecology's website at
htro: / /www.ecy.wa.gov/oroaams hvqLtocmwater/municipal /ghaseIIww/wwphripermit.hunl
The Pexmit allows muniupalities to dischazge stormwatet runofE Ftom municipal dtainage systeins into the state's watex bodies (e.g., stleams, rivers, lakes, wedands) as long as municipaliues implement pzograms to
pmtect water qualiry by xeducing the dischaxge of "non-point source" pollutants to the "maximum extent
practicable" (MEP) through applicadon of Permio-specified °best management pracdces" (BMPs). The BMPs
specified in the Pennit aie collecdvely refecred to as the Stormwater Management Pcogram (S%VMI') and
gzouped under the following Program componencs: '
• Public Education and Ouueach

j The Permit issued by Ecology became effective on February 16, 2007, was modified on June 17, 2009 and
j expues on Febmary 15, 2012. The Pemiit requices the Ciry to xeport annually (Much 3160 oE each yeaz) on
1 psogress in SWMP implementation for the pzevious yeaz. The Permit also xequites submittal of
{ documentation that describes psoposed SWNII' activities for the coming yeaz. This document contains the
Ciry's pzoposed acuvides for 2010. Implementarion of various Permit conditions is staggeced thcoughout the
6ve-yeac Pennit term fxom February 16, 2007 through Februazy 15, 2012. The Pexmit will be xevised and
ieissued at the end of this period. .
! 9.3 City of Auburn Regulated Area
;
The Westem Washington Phase II Pemut applies to opeeators of iegulated small MS4s that discharge
~ stormwater to wafers of Washington State located west of the crest of the Cascade Range (wes[ of the eastem
boundaries of Whatcom, Skagit, Snohomish, King, Pierce, Lewis and Skamania counries). Foz ciries, the
Pemvt xequirements extend to those azeas of each Ciry that drain to MS4s. Most of Aubum dzains to MS4s
~ that ultimately dischazge into the Green River, the White River, or Mill Creek. In addition, some poraons of
I the City dLain to xegional infiltrabon basins.
I,I
1.4 Total Maxemum Daily Load (TlVIDL) Compleance
I The fedexal Clean Water Act requues that Ecology establish "Totat Maxunum Daily Loads" (I'NIDL) for
; rivers, streams, lakes, and marine waters that don't meet water quaGty standaxds. ATNIDL is a calculation of
' the maxtimum amount of a pollutant that a water body can receive and still meet water quality standacds.
~ After the TNIDL has been calculated fot a given watec body, Ecology deteunines how much each soucce
must xeduce its dischazges of the pollutant in oider bring [he water body back into compfiance with the water
quality standazds. The Clean Water Act iequices that TIvCDL requirements must be icicluded in the NPDES
~
pemuts Eox dischazgeis into the affected water bodies. ' i Sroxmwatex dischazges covered under this permit aze iequired to implement actions necessary to acMeve the
i pollutant reducuons called for in applicable'I'MDIs. Applicable TMDIs aie those appzoved by the EPA
befoie the issuance date of the Pemilt oi which have been appsoved by the EPA prior [o the date the
~
Permittee's aPPhcadon was ceceived bY Ecolo$Y Informadon on Ecolo8Y's'I"NML ProBram is availa6le on
I
I Ecology's website ac www.ecy.wa.gov/oromams/wy/tmdl. i
I The cuirent pemut does not contain any TTML requirements fox the Ciry of Aubum. However, Ecology
~ lias idenrified several water bodies that do not appeaz to meet the water quality standazds. If Ecology
establishes T'NIDLs fox one ox moxe of these water bodies priox to 2012, the neact version of the Pexailt may
contain addiuonal requixements specified in the 7'Mff>L. 1.5 SNi/MP /mp/ementation Responsibilities

8. MONITORING
This secuon describes the Permit zequirements related to water quality monitoring, including descriprions of
the City's cuaent and planned compliance activities for 2010. 8.1 Perrnit Requirements
The Pemut (Secuon S8) does not require municipalities to conduct water quality sampling ox other testing
dll[lllg L1715 IJCIIRIL TPSIIl, witn the iollowing excepliuns:
° Sampling or testing required for chaxacterizing illicit dischazges puxsuant to the SWNIl"s IDDE
conditions.
• Watec quality monitoring zequired for compliance with Total Maximum Daily L.oad (TMIJL) _
condiuons (watex quality dean up plans). The cuaent Permit does not requite that Aubuxn petform TNIDL-relared monitoring because Ecology has not established TIv1DLs for watex bodies that zeceive stormwater runoff &om the Ciry. _ • Pxeparing future compxehensive, long-texm water quality monitoring plan including two components: "
_ 1) stormwater moniroring and 2) taxgeted Stormwater Management Pxogram effecdveness monitoring. -
• By the 41' Annual Compliance Repart (Mazch 31, 2011), Auburn is required to identify two outfalls oc
conveyances whexe permanent stormwater sampling stations can be installed and operated for fumse .
monitoring. The Ciry is also zequired to develop plans to monitox stormwater, sediment, and xeceiving .
wates for physical, chemical, and/or biological chaxacterisdcs. One outfall must represent high-density
sesidential land use, and the othex commetcial land use.
• To monitox SWMP eEfecuveness, the Ciry will need to identi£y two suitable Progiam questions and , sites wheTe taxgeted Piograzn effectiveness monitoxing can be conducted and develop a monitoxing plan for these quesnons and sites. The pxoposed effectiveness monitoring is xequited to answex the
following types of quesdons:
. • How effecrice is a specific tazgeted aclion or a narrow suite of acrions?
• Is the Stoxmwates Management Pxogram achieving a taxgeted environmental outmme?
In addition, the City is xequixed to pxovide the Eollowing monitoring and/or assessment data in each annual
zeport:
• A descripuon of any stoxmwater monitoring ox smdies conducted by the City duxing the reporting
period. If stormwatex monitoxing was mnducted on behalf of the Ciry, ox if studies or invesrigadons
conducted by other enudes were reparted to the City, a brief descripdon of the type of information
- gathexed ox received shall be included in the annual repoxt ,
• An assessment of the appropriareness of the best management pracdces identified by the City for each .
component of rhe SWMII'; and any changes made, ox anricipated to be made, to the BMPs that were :
previously selected to unplement the SWMP and why.
