The SWMP Plan is intended to inform the public of the planned SWMP activides foz the upcoming yeaz. The per{nit to dischaxge stomiwater is designed ro zeduce the dischaxge of pollutants,protect water qualiry, and meet the tequuements of the federal Clean Wgfez Act. Appendix A includes aciodyms and defuurions fxom the Pesinit to help the ceader undesstand the City's S[otmwater Management Pzogxam. 1.2 Regulatory Background The Nauonal Pollutant Dischazge F.limination S}�stem(NPDES)pernut program is a requicement of the federal Clean Wate:Act,which is intended to p:orect and cestore watexs Eox"&shable,swimmable"uses. The fedezal Enviuonmenral Pzotection Agency(EPi1) has delegated pesmit authoriry to state envuonmental agendes,and these agencies can set pezmit condidons in accordance with and in addidon to the minimum fedezal zequirements.

In Washingcon,municipaliqes with a populadon of over 100,000 ue designated as Phase I communiries and must comply with Ecology's Phase I NPDES Municipal Stormwatet Pemut.Aubum's population is below the 1OQ000 thxeshold, so the City must comply with the Phase II Municipal Stozmwater Pumit.About 100 oihez�municiPalities in Washington must also comPly with the Phase II Pexmit,as opeiators of small municipa.l sepazate storm.sewer.systems (MS4s). Ecology�'s Phase IlMunicipal�Stoxmwatez Peunit is available on Ecology's website at h�co�//wwwecyw��v/nroersims/wq/swnnwarer/munici al ,phascllww/wwplwpermit.html The Pernut allows municipalities to dischazge stormwatex runoff fiom municipal dcainage systems into the staxe's watez bodies (e.g.,streams,rivezs,lakes,wetlands,and aquifexs) as long as municipalities unplement piogxams to protect watex qualiry by reducing the dischazge of"non-point source"pollutants to the "tnaximum extent piacdcable" (MEP)duough applicauon of Pernut-specified"best management pzacrices" (BMPs).The BMPs speafied in the Pumit aze collectively refezced to as the Stozmwatez Management Ptogram(S�!VMP) and grouped undei the following Pcogram components: • Public Education and Outreach • Public Involvement and Parqcigarion • Illicit Dischazge Detecaon and Eluiutiation • Contxolling Runoff fiom 1Vew Development,Redevelopment, and Construction Sites 7 V�coa.auburn.local�tlepPHuildinyiPUB_WRKSIUtiIIllesl5lormlJP�ES IPAdm:nisiraiion'�nnuel Reporls120�6 Annu21 Ropotl12016 Repon A�tachments�2017 5`NMP Plan Final 20170JW.tlucx 1:Introductlon City of Aubum 2016 SWMP Plan • Muniapal Operations and Muncenance In addirion to rhe SWMP components the Pecmit contains special condidons covenng: • Compliance with Total Ma�cimum Daily Load cequicements • Monitoring and Assessment • Reporting Requirements The Permit issued by Ecology became efEective on August 1,2013,was modified January 16,2014 and eicpues on July 31,2018.
