Copper TMDL Implementation Program

The County of Los Angeles Department of Beaches and Harbors is working on several efforts to help reduce copper pollution from antifouling paints in the Marina del Rey Harbor. The newest program provides an opportunity for interested boaters to receive a rebate for a portion of the cost to convert their boats to a non-biocide hull paint. The purpose of this survey is to learn more about the non-biocide hull paints currently in use in the Marina del Rey Harbor and to invite interested boaters to learn more about the Marina del Rey Harbor Pilot Hull Paint Conversion Program as well as other efforts being implemented in the Harbor.

Question Title

* 1. Do you currently have non-biocide hull paint on your boat?

Question Title

* 2. If you currently have a biocide hull paint (e.g. copper, zinc, econea, etc.), would you be interested in converting your boat to a non-biocide hull paint (e.g. ceramic, silicone, etc.) through a rebate/discount program being offered through the Department of Beaches and Harbors?

Question Title

* 3. If you responded no, why are you not interested in converting your boat to non-biocide hull paint?

Question Title

* 4. What type of boat do you own?

Question Title

* 5. What is the size/length of your boat?

Question Title

* 6. At which anchorage in Marina del Rey Harbor do you rent a slip / dock for your boat?

Question Title

* 7. What activities do you use your boat for?

Question Title

* 8. How often do you take your boat out of the slip?

Question Title

* 9. How long ago was your current hull paint applied?

Question Title

* 10. Where did you get your boat hull painted?

Question Title

* 11. About how long until your current hull paint will need repainting?

Question Title

* 12. How often do you clean your hull in the summer?

Question Title

* 13. How often do you clean your hull in the winter?

Question Title

* 14. Approximately how much does it cost to have your hull cleaned (single cleaning)?

Question Title

* 15. Have you experienced any issues with your current hull paint?

Question Title

* 16. Would you like to be added to the Marina del Rey Harbor Boating Stakeholder Group email list? This group will meet every few months to discuss experiences with non-copper and non-biocide hull paints, as well as other topics and programs related to the Marina del Rey Harbor water quality program and TMDL implementation. If interested, please provide contact information.

The Marina del Rey Harbor is designated as impaired water body on the State’s 303(d) list due to high levels of copper in the water column. The leading contributor to copper in the water column is from boats with copper leaching antifouling hull paints. To address copper pollution, the Regional Water Quality Control Board (Regional Board) developed a Total Maximum Daily Load (TMDL) for dissolved copper in the Marina del Rey Harbor. A TMDL sets limits on how much pollutant can enter a water body. To enforce the copper TMDL, the Regional Board assigned load allocations for discharges of dissolved copper to the County, individual anchorages, and persons owning boats moored in the Marina. The State has the authority to implement these regulations through waste discharge requirements and other regulatory mechanisms if the copper loading in not reduced.
 
Two solutions the Regional Board has identified to reduce copper in the water column is to convert 85% of boats to non-copper based paints or to reduce the leaching of copper levels by 85% for 100% of the boats in the Marina del Rey Harbor. As part of its efforts to help the Marina del Rey Harbor comply with the water quality regulations, the County has developed a number of programs to help reduce copper loading from boats. These copper reduction programs are designed to provide opportunities for anchorages and boat owners to reduce their copper before the State requires enforcement of the regulations. One of the programs being offered in the Harbor is the Pilot Hull Paint Conversion Program that will provide a rebate to boaters who convert to a non-biocide paint.
