Industrial Stormwater General Permit

In late 2007, the Washington State Department of Ecology (Ecology) issued a draft revised Industrial Stormwater General Permit (ISWGP) under the National Pollutant Discharge Elimination System (NPDES) program. During the public comment period, the draft received significant critique and it became apparent that the permit could be headed for several years of litigation with very little resultant environmental benefit. In April 2008, Ecology delayed issuance of the revised permit and convened a Work Group comprised of key stakeholders to re-evaluate the ISWGP to find practical solutions for managing industrial stormwater discharges for improved environmental results.
Floyd|Snider was hired to facilitate the Work Group meetings convened between August 2008 and February 2009 to assist stakeholders in providing recommendations to meaningfully assist Ecology in developing the next draft of the permit. The Work Group was comprised of ten members who represent the primary permittees and interest groups relative to the ISWGP, including large and small industry, Ports, City and County industrial permittees, and environmental non-governmental organizations. The meetings were open to the public, with opportunities for participation. The Work Group effort resulted in a set of documented recommendations to Ecology for consideration in issuance of the new permit, and recommendations for a new implementation support structure to provide permittees with technical assistance and to increase overall enforcement effectiveness.
