1.INTRODUCTIONThis report represents the Stormwater ManagementProgram (SWMP) Plan prepared by the City of Newcastle(City) in accordance with the National Pollutant DischargeElimination System (NPDES) Phase II Western WashingtonMunicipal Stormwater Permit (Phase II permit). The PhaseII permit is a requirement of the federal CleanWater Act(CWA), and in some states, the federal EnvironmentalProtection Agency (EPA) delegates permit authority tostateenvironmentalagencies.InWashington,theNPDESpermit authority is theWashington StateDepartment ofEcology(Ecology).

ThePhase IIpermit requirest he Cityto d e ve l op a SWMPPlan that includes numerous actions andactivities with the overall goals of protecting the water quality and of reducing the discharge ofpollutants from its m u n i c i p a l s e p a r a t e storm sewer system (MS4), to the maximum extentpracticable (MEP).The actions and activities are described in a number of program components underSection S5 of the Phase II permit. The Phase II permit directs the City to prepare a SWMP documentthat includes a description for each of the programcomponents.

This section provides: background information on the Phase II permit; a mission statement from theCity regarding its stormwatermanagement activities;and f inally, this section outlines the structure fortheremainderoftheSWMPPlan.

1.1 NPDESPhaseIIPermitBackgroundThe followingprovidesabriefbackground to, andoverviewof, thePhase IIpermitprocesses thathaveoccurredtodate:

• ThefederalCleanWaterAct (CWA)wasmodified in1987to includestormwater intheNPDES permit program. That is, a municipality such as the City, will need an NPDESpermit to discharge stormwater from its municipal storm sewer system, or MS4, towaters ofthestate.

• In the state ofWashington, the EPA Ecologytheauthoritytoissue suchpermits.

• In 1999, EPA issued final Phase II rules to include all municipalities in census-definedurbanareaswiththecurrentpopulationgreaterthan1,000.

• The City is determined to be an operator of a regulated small MS4, in an Ecology-designatedurbanizedarea,and is therefore requiredto submit for approval andreceive coverageunderaPhaseIIpermit.EcologydevelopedthePhaseIIpermit,whichallowstheCitytodischarge stormwaterfromitsMS4intosurfacewatersofWashingtonState,providedtheCityimplements aSWMPto:

• Reduce the discharge of pollutants from its MS4 to the maximum extentpracticable (MEP)

• MeetstateAKART(AllKnown,Available,andReasonableTechnologies)standards

• Protectwaterquality

5


This Phase II permit authorizes discharges of non-stormwater flows to surface waters and togroundwatersofthestatefromtheCity’sMS4onlyunderthefollowingconditions:

• ThedischargeisauthorizedbyaseparateNPDESorStateWasteDischargepermit.

• Thedischargeisfromemergencyfire-fightingactivities.

• The discharge is from another illicit or non-stormwater discharge that ismanaged bythe CityasprovidedinSpecialConditionSectionsS5.C.3.bandS6.C.3.bofthepermit.

ThePhase II permit requires theCity todevelopa SWMPthat includes the followingcomponents fromSectionS5.Cofthepermit:

• PublicEducationandOutreach

• PublicInvolvementandParticipation

• IllicitDischargeDetectionandElimination

• ControllingRunofffromNewDevelopment,Redevelopment,andConstructionSites

• PollutionPreventionandOperationandMaintenanceforMunicipalOperations

• MonitoringandAssessment

TheSWMPdocument isalsointendedto includeanyadditional informationonmeetingapplicableTotalMaximum Discharge Limits (TMDLs) pursuant to Section S7 of the Phase II permit. Since no TMDLsapplytotheCity’sreceivingwatersatthistime,thisreportdoesnotaddressTMDLissues.

The City is required to report annually on progress in permit implementation for the prior year, andsubmitaSWMPPlan thatdescribes theprogramactivities for thecomingyear. The implementationofvariouspermit conditions isphased throughout the five-yearpermit term,August1,2013 through July31,2018.

1.2CityofNewcastleMissionStatement

The City is dedicated to developing, implementing, and enhancing an adaptive stormwatermanagement program that is committed to protecting water quality and the environment, andreducingpollutantsinourstormwatersystems. TheSWMPPlanprovidesanoutlineofactionsandactivitiesthattheCityutilizestoaccomplishthesegoals.TheCityiscommittedtocontinuingto build successful stormwater programs, reviewing programs and making adaptations asnecessary, and continuing to coordinate and collaborate with other jurisdictions, agencies,organizations,businessandpropertyowners,residents,andotherstakeholderstoachieveourgoalsofprotectingwaterquality,theenvironment,andreducingpollutants.

The SWMP Plan is updated annually, and is considered a working document that will be modified asnecessary to reflect adaptationsthatcontributetoasuccessfulprogram.TheCitywillmakeeveryeffortto be transparent with suchmodifications through its public education and involvement programs aswell as through the annualSWMPPlansubmittalprocess.
