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

Draft Permit Modification: The department of ecology (ecology) issued a 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, man-made channels, and storm drains. A minor modification was made to this permit on May 1, 2009, to correct minor, nonsubstantive errors found after permit issuance.

A second modification added 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.

The second permit modification required ecology to modify or issue an administrative order establishing new TMDL-related permit requirements for WSDOT at least every eighteen months. The proposed draft modifications make substantive changes to the permit including adding new TMDL-related permit requirements in Appendix 3, making references to the 2012 updated highway runoff manual (HRM) instead of 2008 HRM, and updating the stormwater management program plan (SMPP) in Appendix 7.
