This National Pollutant Discharge Elimination System (NPDES) water quality permit helps ensure that the disposal of wastewater from boatyards causes no harm to the environment, in accordance with the federal Water Pollution Control Act and state Water Pollution Control laws.

You may need this permit if:

    • At least 85 percent of which are 65 feet or less in length; OR
    • Your revenues from working on vessels constitute more than 85 percent of gross receipts.

Boatyards include mobile and do-it-yourself facilities that may build a limited number of custom boats.
