Announcing the Draft Washington State

Department of Transportation Municipal Stormwater General Permit

The Draft Washington State Department of Transportation Municipal Stormwater General Permit: The department of ecology (ecology) proposes to issue a general permit to the Washington state department of transportation (WSDOT) to cover discharges from its municipal separate storm sewer system (MS4). MS4s are conveyances or a system of conveyances including roads with drainage systems, streets, catch basins, ditches, man-made channels, and storm drains. Upon issuance, this permit will replace WSDOT's existing coverage under the Phase I Municipal general permits (WASM10001, WASM20001, and WASM30001) for the activities that WSDOT uses to manage stormwater runoff to surface waters of the state. The revocation and replacement is effective beginning on the effective date of this permit.

State and federal regulations require WSDOT to have national pollutant discharge elimination system (NPDES) permit coverage in areas covered by Phase I and Phase II of the municipal stormwater permit program. Seeking coverage under a statewide permit is consistent with WSDOT's objective of implementing a highway stormwater management program that promotes sound stormwater management on all state highways. This general permit will cover stormwater runoff from state highways, rest areas, weigh stations, park and ride lots, ferry terminals, and maintenance facilities. The proposed permit addresses these legal requirements and regulates the discharge of pollutants to protect surface water quality in Washington state. Ecology is requesting public comment on the draft permit and fact sheet. Concurrently, an interagency agreement (IA) regarding the statewide application of the 2008 updated Highway Runoff Manual (HRM) and WSDOT's stormwater management program will also be available on ecology's web site for review and comment.

Ecology expects to issue the permit on or about July 31, 2008, if there is no substantial change to the draft. The permit will be effective thirty days later. When issued, ecology will send a copy of the notice of issuance and ecology's responses to the comments to all persons who submitted written comment or gave public testimony.
