The California Professional Divers Association

California Professional Divers AssociationThe California Professional Divers Association (CPDA) is a non profit mutual benefit corporation registered in California that has been actively promoting hull cleaning BMP’s and the use of biocide free hull coatings.

The CPDA was a voting member on Senate Bill 315 Committee for Environmentally Superior Hull Coatings. The results produced by this committee were used by the Regional Water Quality Control Board to develop the TMDL for the Shelter Island Yacht Basin. The CPDA Board of Directors attended all of the Regional Water Quality Control and State Water Control Board meetings concerning the approval of the TMDL.

The CPDA helps defend the rights of professional divers and hull cleaners so that unnecessary restrictions aren’t imposed when dealing with copper based anti-fouling paints.
