TheMunicipalRegionalStormwaterNationalPollutantDischargeEliminationSystem(NPDES)PermitforPhaseIcommunitiesintheSanFranciscoBay(OrderR2‐2009‐0074),alsoknownastheMunicipalRegionalPermit(MRP),becameeffectiveonDecember1,2009.TheMRPappliesto76large,mediumandsmallmunicipalities(cities,townsandcounties)andfloodcontrolagenciesintheSanFranciscoBayRegion,collectivelyreferredtoasPermittees.ProvisionC.10.coftheMRPrequiresPermitteestosubmitaLong‐TermTrashLoadReductionPlan(Long‐TermPlan)byFebruary1,2014.Long‐TermPlansmustdescribecontrolmeasuresthatarecurrentlybeingimplemented,includingthelevelofimplementation,andadditionalcontrolmeasuresthatwillbeimplementedand/orincreasedlevelofimplementationdesignedtoattaina70%trashloadreductionbyJuly1,2017,and100%(i.e.,“NoVisualImpact”)byJuly1,2022.
