Boatyard General Permit
A boatyard is a service business engaged in construction, repair, and maintenance of small vessels, at least 85% of which are 65 feet or less in length, or revenues from which constitute more than 85% of gross receipts. Boatyards include mobile facilities and may build a limited number of custom boats.
Boatyard operations often produce wastewater and stormwater that they must dispose of safely. In accordance with the federal Water Pollution Control Act and state Water Pollution Control laws, Ecology helps to ensure that the disposal of these wastewaters causes no harm to the environment.
Ecology requires boatyard facilities to have an NPDES permit to protect rivers and other water bodies that receive wastewater discharges. More info
Ecology has re-issued the Boatyard NPDES and State Waste Discharge General Permit. The new Permit and Fact Sheet, which explains the technical and legal bases for the Permit, are available in the Current Permit section below.
