Public Workshops and Hearings to Accept Comments on the

Draft Industrial Stormwater General Permit

The Industrial Stormwater General Permit: The industrial stormwater NPDES and state waste discharge general permit (ISWGP), issued by the Washington state department of ecology (ecology) on September 20, 2002, expired on September 20, 2007. Ecology reissued its ISWGP on August 15, 2007, without changes for an interim period (until May 31, 2008) while we redeveloped a new draft permit.

Ecology has revised the permit for a second public comment period. The proposed draft ISWGP and fact sheet are available for review and public comment from November 21, 2007, until 5 p.m. PST on January 10, 2008.

Ecology redeveloped a second draft permit for public comment using input from internal and external stakeholders. Ecology received a wide spectrum of comments addressing proposed requirements in the first draft permit, including comments on a new approach to permitting recommended in a report delivered to the legislature in December 2006. Three issues emerged from the comments that require reconsideration of decisions made for the February 2007 draft. The three issues are:

The basis of the benchmarks.
Use of the season median of sample results to trigger corrective action.
The corrective action program to remedy benchmark exceedances.
You may review the second draft permit and fact sheet at the web site The fact sheet provides information on the industries covered under the permit, including discharge characteristics, compliance with the previous permit, and the legal and technical basis for the permit conditions.

Requesting Copies of the Permit: You may download copies of the draft permit and fact sheet from the web site; or you may request copies from Julie Robertson, phone (360) 407-6575, e-mail

Submitting Written and Oral Comments: Ecology will accept written and oral comments on the second draft ISWGP and fact sheet. Comments should reference specific text when possible and address the following:

Technical issues.
Accuracy and completeness of information.
The scope of facilities proposed for coverage.
Adequacy of environmental protection and permit conditions.
Any other concern that would result from issuance of the revised permit.
Ecology prefers comments be submitted by e-mail to Written comments must be postmarked or received via e-mail no later than 5 p.m. PST, January 10, 2008.

You may provide oral comments by testifying at the public hearings.
