Announcing the Public Comment Period and Hearing for the Draft Water Treatment Plant General Permit and Fact Sheet
The department of ecology (ecology) proposes to reissue the water treatment plant national pollutant discharge elimination system waste discharge general permit (permit). The permit was last issued in July 2009 and is scheduled to expire at the end of August 2014. The new draft permit and fact sheet, which explains the technical bases for the permit, are available for review and public comment from April 16, 2014, through May 31, 2014, at 5 p.m. Ecology will host an informational workshop and a public hearing on the draft permit.
Purpose of the Permit: The permit provides coverage for certain water treatment plants located in Washington state that produce potable or industrial supply water and discharge backwash effluent from certain water treatment filtration processes. Under federal and state water quality law (federal Clean Water Act and state Water Pollution Control Act), a permit is required for the discharge of wastewater. The federal definition of wastewater includes backwash effluent from water treatment plants. Certain water treatment plant facilities that produce finished water at a rate of at least 35,000 gallons per day and that discharge wastewater either directly or indirectly to surface water must obtain permit authorization for their discharge.
Applying for Coverage Under the Permit: Facilities that applied for coverage and are covered under the existing permit will also be covered under the new permit. New or unpermitted facilities may obtain coverage under the permit by submitting a complete permit application to ecology and satisfying all applicable public notice and State Environmental Policy Act requirements (WAC 173-226-200). Access to the application is available online
