Ecology to engage interests to update industrial stormwater permit

The Department of Ecology will initiate a collaborative effort with the regulated community and environmental interests to develop a simpler and more effective version of the next industrial stormwater general permit.

Ecology won’t finalize the draft industrial stormwater general permit that it offered for public review in November 2007. The move is based, in part, upon public comments the agency received. Also weighing in is a significant budget shortfall Ecology faces in the permit fee account that funds much of its water quality protection work, including supporting and administering this permit.

Ecology has convened a work group to help it address the permit-fee revenue shortfalls. The agency is also looking at more cost-effective methods to administer this and other permits designed to protect water quality.

While a new permit is in development, the protections under the existing permit will remain in effect.

Ecology will take near-term steps under the existing permit – for example, through training and enforcement, to help industries improve their water pollution controls.

Ecology revised this permit and issued a draft permit for pubic review in November 2007. Most recently, Ecology had been on track to issue a final permit in April 2008.

The current permit expires May 31, 2008. Existing permit holders will remain covered in the interim. New applicants should submit their applications to Ecology as usual. The current permit still applies to all facilities that are covered by the permit prior to May 31, 2008.

If you have questions, please contact Interim Water Quality Program Manager Kelly Susewind at 360-407-6872 or email ksus461@ecy.wa.gov

Purpose of the Industrial Stormwater General Permit

Under federal and state water quality law (federal Clean Water Act and state Water Pollution Control Act), the discharge of wastewater, including stormwater, requires a permit. The Code of Federal Regulations (CFR) Title 40, Part 122.1 (b) (40 CFR 122.1 (b)) requires permits for the discharge of pollutants from any point source into waters of the United States. 40 CFR 122.26(b)(14) (i) -(xi) identifies the industries required to apply for coverage under the Industrial Stormwater General Permit. A general permit applies to a group of dischargers as a whole and implements both the federal Clean Water Act and state Water Pollution Control Act. The draft general permit addresses legal requirements and controls the discharge of pollutants to protect surface water and ground water quality in Washington State under the authority of Revised Code of Washington (RCW) 90.48.260. Facilities in the industrial sectors listed in the draft permit and on the Industrial Stormwater General Permit website will require permit coverage. Currently, 1,153 industrial facilities are covered under the permit.

Appeal of the Industrial Stormwater General Permit

Pursuant to RCW 43.21.B.310, the modified terms and conditions of the permit may be appealed within 30 days of receipt of the modified general permit. An appeal must be filed with the Pollution Control Hearings Board, PO Box 40903, Olympia, Washington, 98504-0903. In addition, a copy of this appeal must be served on the Department of Ecology, PO Box 47600, Olympia, Washington, 98504-7600. The procedures and requirements for the appeal process are contained in chapter 43.21.B RCW.

The terms and conditions of a general permit, as they apply to an individual discharger, are appealable within 30 days of the effective date of coverage of that discharger, in accordance with chapter 43.21B RCW. This appeal is limited to the general permit's applicability or nonapplicability to a specific discharger.

Industrial Activities that Require a Stormwater Permit

Permit coverage is required for industrial facilities that have specific Standard Industrial Classification (SIC) codes (click here for a list of industrial activities that require a stormwater permit), if they have a discharge of stormwater from their industrial areas to a receiving water of the state, or to storm drains that discharge to a receiving water. Regardless of the SIC code, some industries may be required to seek permit coverage for areas of their industrial site that have a potential or are causing an impact to receiving waters.  If you discharge all the stormwater to a Combined Sewer (which goes to the wastewater treatment plant), you are not required to apply for coverage. Check out Ecology's Industrial Booklet for more details.
