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.

Ordinance Highlights

  • BMP Certification is required for all persons performing in-water hull cleaning
  • Hull cleaning resulting in a visible paint plume is prohibited
  • All persons conducting in-water hull cleaning in Marina del Rey Harbor are required to have a Commercial Service ID issued by the Harbor Master
  • Penalties:
    • First 2 violations: Infraction with a fine of up to $250
    • Third violation: Misdemeanor

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.

All divers that perform in-water hull cleaning in Marina del Rey Harbor must complete the training and obtain a burgee (see below) from Beaches and Harbors to show they are BMP-certified and in compliance with Los Angeles County’s Ordinance. Hull cleaners: please email to receive access to the free online training.
  • Burgees: Burgees will be distributed to BMP-certified hull cleaners to display on their boat while in Marina del Rey Harbor. The burgee indicates the diver has completed the Marina del Harbor In-Water Hull Cleaning BMPs Training and is BMP-certified. To obtain a burgee, divers will need to:
    • Complete the online training and receive a certificate of completion.

Hull Cleaning Training

The Department of Beaches and Harbors, in association with the California Professional Diver’s Association, hosted a free Hull Cleaning BMP training on Saturday, February 2, 2019, at Burton W. Chace Park Community Center. More than 45 divers from Marina del Rey and surrounding areas attended the training and have received a Hull Cleaning BMP training certificate that can be used to comply with the new regulations.
