Posted: June 13, 2013 | By: EPAIn California, and in coastal communities throughout the United States, water quality is significantly impacted by the copper used to coat boat hulls, large and small. The California Department of Toxic Substances Control (DTSC), a grantee of EPA, identified cost-effective methods for boat owners to protect both their boats and water quality. EPA’s grant assisted DTSC in identifying boat hull coatings that can reduce copper pollution in marinas, while boosting boat performance and cost-effective maintenance over the long-term. Like its predecessor EPA grant, implemented by the Unified Port of San Diego, this project successfully established the viability of non-copper anti-fouling boat hull coatings for both performance and cost-effectiveness. However, while the San Diego project looked at both biocide and non-biocide coatings, in this DTSC project, the grantee solely studied the effectiveness of non-biocide coatings, as well as alternative painting and stripping methods.
