Announcing a Proposed Modification of the Washington State Department of Transportation Municipal Stormwater General Permit for Review and Comment

Proposed Permit Modification: The department of ecology (ecology) issued a general permit to the Washington state department of transportation (WSDOT) on January 21, 2009. The permit covers 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, manmade channels, and storm drains. The effective date of this permit was February 21, 2009.

This proposed modification adds substantive language to the permit as a result of a settlement agreement between the departments of ecology and transportation and Puget Soundkeeper Alliance. Permit sections modified include: S6.C, S7. E.2.d., S8.E., Appendix 7, Stormwater Management Program Plan, Sections 3 and 3.1, 5.4, 6.2, and Appendix 3, Applicable TMDL Requirements.

Purpose to the 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. This permit covers stormwater runoff from state highways, rest areas, park and ride lots, ferry terminals, and maintenance facilities. The permit addresses these legal requirements and regulates the discharge of pollutants to protect water quality in Washington state.
