Announcement of Modification - NPDES General Permit

for Boatyards

Introduction: On November 1, 2005, Washington state department of ecology (ecology) reissued the boatyard general permit, a National Pollutant Discharge Elimination System (NPDES) and state waste discharge general permit for boatyards in Washington state. This permit became effective on December 2, 2005. The permit implements the Federal Clean Water Act and State Water Pollution Control Act. The purpose of the permit is to control the discharge of pollutants from boatyards into waters of the state.

Boatyards conducting the following activities are required to obtain coverage under this permit: Pressure washing of boat hulls; bottom and top-side painting; engine, prop, shaft, and rudder repair and replacement; hull repair, joinery, bilge cleaning; fuel and lubrication system repair or replacement; welding and grinding on the hull; buffing and waxing; top-side cleaning; MSD (marine sanitation device) repair or replacement, and other activities necessary to maintain a vessel.

Proposed Modification of the General Permit: The fact sheet accompanying the boatyard general permit showed calculations for the derivation of the benchmark for discharge of stormwater to lakes. The calculation resulted in a value of 38µg/l. A benchmark value of 77µg/l was inadvertently placed in the permit. This modification of the boatyard general permit places the correct benchmark value of 38µg/l into the permit. You may view the modified permit at or request a copy from the contact listed below for obtaining additional information.

Effective Date: This permit modification becomes effective on May 20, 2006.
