Final Washington Industrial Permit Effective July 1, 2012

The Washington Department of Ecology (Ecology) has issued a final modified Industrial Stormwater NPDES and State Waste Discharge General Permit May 16, 2012. The modified permit is effective July 1, 2012. The permit modification is necessary to address the April 25, 2011 order by the Washington State Pollution Control Hearings Board, which required significant changes to the sampling and corrective action requirements. Ecology has also made revisions to the effluent limits for fecal coliform that apply to approximately 80 facilities discharging to 303(d)-listed impaired waterbodies. Other minor changes were made in response to public comments and to correct various errors and typos.
