In 2018, Los Angeles County passed an ordinance that requires commercial and private in-water hull cleaners to use best management practices (BMPs) for all in-water hull cleaning activities in Marina del Rey Harbor. In-water hull cleaning activities have been identified as a leading source of copper pollution in the harbor. Using BMPs during in-water hull cleaning has been shown to dramatically reduce contaminant loading of pollutants such as copper to the water column and sediment from boat hull paints.

Hull Cleaning Best Management Practices (BMPs)

The main objective of implementing BMPs is to eliminate pollution generated during in-water hull cleaning operations. Additional benefits of BMPs may include improving vessel performance, reducing fuel consumption and emissions, and extending the life of bottom paints.

BMPs for in-water hull cleaning were initially developed under the Sea Grant Program in 1990 by the California Professional Divers Association (CPDA). The BMPs have since been further developed to specifically address copper impaired waters and several studies have shown that the use of BMPs during in-water hull cleaning reduces copper loading significantly.

How to Obtain Hull Cleaning BMP Training & Certification

  • Training/Certification. Hull cleaners must attend an In-water Hull Cleaning BMP training offered by a qualified trainer whose content has been reviewed and approved by Beaches and Harbors. Upon completion, the trainer will provide a completion certificate, which can be used as proof of BMP certification when obtaining or updating the Commercial Service ID from the Harbor Master. Currently, CPDA is the only organization whose content has been reviewed and is approved by Beaches and Harbors for In-water Hull Cleaning BMP Training for LA County harbors.
  • Re-certification. BMP certification is valid for four (4) years from the date of completion. Proof of re-certification is required every four years.
  • Future Trainings. Details about future trainings offered by Beaches and Harbors will be posted here. Please complete the form at the bottom of this page if you would like to receive notifications about future training opportunities.
