Copper Reduction Program

The Port’s Copper Reduction Program will help to improve water quality and reduce copper in San Diego Bay.

Attention Boaters and In-Water Hull Cleaners

As part of the Port of San Diego’s Copper Reduction Program and on-going efforts to improve water quality in the Shelter Island Yacht Basin (SIYB) and San Diego Bay, the Port is considering an eight-week pause on in-water hull cleaning of boats with copper-based paint in the SIYB to begin in December of this year. The pause will reduce copper loads and improve water quality during that period and weekly water testing will be conducted.

As the mechanism to implement the temporary in-water hull cleaning pause, Port staff will be going to the Board of Port Commissioners to formally seek adoption of the draft amendment to Article 4.14 of the District Code, Regulation of In-Water Hull Cleaning, at the Board of Port Commissioners’ October 12, 2021 monthly Board meeting. The public is invited to participate in the meeting. The agenda and details on how to participate will be posted here on or shortly after Thursday, October 7. 
 
Interested parties can find the Draft In-Water Hull Cleaning Pilot Pause Study Sampling and Analysis Plan here, and the draft proposed Amendment to Article 4.14 of the District Code, Regulation of In-Water Hull Cleaning, here as a red-line/strikethrough, and here as a clean version.

Copper Reduction Program

The Port of San Diego is a regional leader in improving water quality in San Diego Bay. Through the Copper Reduction Program, the Port is engaging with the boating community to reduce levels of dissolved copper in marina basins around the bay as it can be harmful to marine animals and plants.

The Port’s Copper Reduction Program focuses on the largest source of copper - boat hull paints - and identifies an approach to improve water quality and achieve compliance with regulations while balancing economic and public interests. The Board of Port Commissioners Resolution (2009-230) champions copper reduction as part of its environmental stewardship mission.  

In San Diego Bay, Shelter Island Yacht Basin (SIYB) has been identified as an area where high copper levels exceed federal and state standards. A regulatory order requires the Port of San Diego, marinas, yacht clubs, hull cleaners and boaters to reduce copper pollution in this area by 76 percent by 2022. Together with the boating community, we’ve reduced copper loading in SIYB by 45 percent to improve water quality.

The Dissolved Copper Water Quality readings show regulatory listings for water body impairments around San Diego Bay. Below is a recent assessment of copper levels in San Diego Bay:

The Port's Copper Reduction Program focuses on:

  • Policy development and legislation related to in-water hull cleaning and hull paints
  • Conducting site-specific and baywide monitoring
  • Encouraging hull paint conversions 
  • Conducting hull paint testing and research
  • Conducting community outreach and engagement 

In-Water Hull Cleaning Policy Development

The Port of San Diego adopted In-Water Hull Cleaning regulations in 2012 to reduce or eliminate copper pollution caused by hull cleaning activities in San Diego Bay. The ordinance requires the use of Best Management Practices (BMPs) for anyone doing in-water hull cleaning. The In-Water Hull Cleaning Permit is a bay-wide permit that all businesses must obtain prior to conducting in-water hull cleaning services.

In late 2019 into early 2020, Port staff conducted outreach and engaged with the boating community regarding proposed amendments to the Port's proposed ordinance for in-water hull cleaning. To view all supporting documents and resources,click here. To access comments received during the draft ordinance public comment period,click here. The Port appreciates the engagement and comments received on the this topic. Port staff continues to evaluate the feedback and potential next steps.

The Ordinance (adopted in 2012)

  • Requires the use of BMPs for any business doing in-water hull cleaning on recreational or commercial boats
  • Requires permits for all hull-cleaning businesses
  • Ordinance No. 2681

The Permit

  • All hull cleaning businesses are required to obtain a permit
  • The permit fee is $250
  • Appointments must be made to conduct any transactional business related to the Hull Cleaning Permit
  • List of Permitted Hull Cleaning Companies

 

*The Port is currently reviewing and seeking to update existing policies related to in-water hull cleaning. Until the review is complete, please send any inquiries regarding obtaining or renewing a permit to hullcleaning@portofsandiego.org.

Legislation Support

One of the goals of the Copper Reduction Program is to promote regulatory change at the state level and to develop local policies, procedures or permits to address copper pollution. Over the past several years, the Port has supported multiple state representatives and their regulations that impact the water and air quality.

The Board of Port Commissioners has also:

  • Supported the California Environmental Protection Agency Department of Pesticide Regulation's re-evaluation of hull paints;
  • Approved the Port's environmental department receiving a $180,000 grant from the Environmental Protection Agency to study alternative paints;
  • Approved a State 319h grant for $600,000 to assist boaters in switching from copper-based hull paint to a non-copper alternative;
  • Approved three grants totaling $230,000 through the Port's Environmental Fund for outside parties to develop alternative hull paints; and
  • Approved projects aimed at reducing copper in water through the Blue Economy Incubator.

 

In-Water Hull Cleaning Survey

As part of our Copper Reduction Program, the Port of San Diego invited boaters, hull cleaners, and marina and yacht club operators and managers in the San Diego Bay boating community to participate in our In-Water Hull Cleaning Survey to help the Port better understand how vessels are being cleaned. 

Thank you to all who took the time to complete the survey! We received approximately 450 responses. 

The Port has compiled the data in a series of graphs and figures for the responses provided and is pleased to share the findings with you. Please find posted below the graphical summaries by survey group (boaters, hull cleaners, and marina and yacht club operators and managers).

The Port will be using the information to better understand the cleaning strategies used in San Diego Bay and inform potential next steps in our collective effort to improve water quality.

Hull Paint Conversion

Converting to non-copper hull paint is foundational to the Port’s Copper Reduction Program. Reducing the use of copper hull paint - a major source of copper pollution in marina basins - will help improve water quality.

 The Port is helping to spread awareness of non-copper alternatives by funding research projects, testing non-copper hull paints in San Diego Bay, and developing outreach materials and tools.

Leading By Example: The Port has converted all boats in its fleet to non-copper hull paints. The fleet includes both Harbor Police boats and General Services work boats.

Alternative Hull Paints

 

Copper from anti-fouling hull paints can be a significant source of water pollution in marina basins. Copper harms marine life by impeding or altering their development. As a result, boaters are encouraged to consider converting to alternative hull paints that are better for the environment. 

The Environmental Protection Agency provided funding for the Port of San Diego to conduct a study that evaluated a variety of alternative hull paints. The three-year study, “The Safer Alternatives to Copper based Antifouling Paints,” evaluated a variety of alternative hull paints. Twenty-one of these paints performed well when compared to copper hull paints and 11 were further tested in real-life scenarios on boats. The study concluded that alternative hull paints are environmentally-friendly, cost-effective and are an effective replacement.

Boater Testimonials

“I get underway about twice a month, I bring the boat up to its cruising speed for a few minutes, which I’m normally doing in my operation anyway, and all the marine growth flies off the bottom of the boat.”

~ Todd Roberts (Bottomspeed)

“The cleaning has been cut down…some boats it would take three hours to clean…and now… we can get in there and clean it in fifteen to twenty minutes. I can just use my glove to clean it. I can actually just use a glove!”

~ Thomas Hahn (Intersleek 900)
