Phase II pe;mit covecs dischazges fzom zegulated small municipal sepazate stoim sewex systems (MS4s). 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

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 Washington,the NPDES-delegafed pemvt authority is the Washingcon State
Depazhnent of Ecology(Ecology).
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

8. COMPLIANCE WITH TOTAL MAXIMUM DAILY LOAD
REQUIREMENTS
The fedexal Clean Vi/atex Act zequizes that Ecology establish"Total Maxinium Daily Loads" (TMDL) foz
rivers,streams,lakes,and mazine wa[ecs that don't meet watei qualiry standazds. A TMDL is a calcularion of
the masimum amount of a pollutant that a water body can ieceive and still meet watez quality standazds.
rlfxer the TMDL has been calculated foz a given wacec body,Ecology deurmines how much each source
must zeduce its dischazges of the pollutant in order bring the water body back into compliance with the watez
qdality stanflaxds. TI�IDL requirements aze included in the stonnwatei NPDES pemuts fox dischazges into
affected warer bodies.
Stormwarec dischazges covesed undei this Pecmit are cequiued to unplement actions necessary ro achieve the
polliitant ieducdoiis called foL in applicable TMDLs. Applicable'P14IDLs aze those approved by the EPA
befoie the issuance date'ofthe Pemut or wkuch habe been approved by the EPA prioz to the issue date oE the
