3. TONIGHT’S GOALS
1. Inform and educate Boaters and Anchorages about the TMDL
2. Heighten your awareness of the TMDL’s critical timelines
3. Ask for your support to…
Educate others on the TMDL; e.g. distribute hull maintenance brochures and other TMDL related materials
Meet with and write to your Congressman to ask that the EPA adopt the Marine Biotic Ligand Model (BLM)
Ask the County to seek and the Regional Board to provide 319 h Grant Funding for boater conversions to low copper/alternative paints
Begin planning now to implement Best Management Practices
Use best practices for Hull Cleaning
Use of only Certified Divers
Consider cap on cleaning frequency to e.g. bi-monthly
Be prepared to convert to “Diet Copper” or alternative paints
4. Coordinate with each other and strengthen our coalition of interested parties

9. Copper Bottom Paints – A Rational Approach for Marina del Rey
Greg Schem, CEO
Victor Espino, Service Manager
Harbor Real Estate Group, LLC
March, 2015

10. Bio-fouling over the Years
Techniques of using copper and pitch date back to 1500 BC by Carthaginians and Phoenicians
Royal Navy adds copper to fleet beginning 1770
“Copper-Bottomed”: certain or reliable, trustworthy
What is a biocide? Pesticide?
Iron Hulled Ships, electrolysis issues leads to development of metal oxide paints
Strong Biocides: TBT, Lead, Arsenic
New Biocides: Non-Copper vs Biocide Free Confusion
Econea, Zinc, Soft bottoms, ultrasound, nanotechnology

11. Copper Bottom

12. Bio-Fouling Organisms

13. California Regional Water Quality Control Board (“RWQCB”)
2006: Portion of MDR is Designated as an “Impaired Waterway”
2014: Reconsideration Meeting (February), All of MDR designated Impaired along with Sediment
TMDL
Copper, Lead, Zinc, Chlordane, DDT, PCB’s, etc.
Problem for: Water Contact, Shellfish Harvesting, Commercial and Sportfishing, Wildlife Habitat, Marine Habitat.
10 years to Reduce Copper by 85%
Potentially Dredge Entire Marina One Foot Deep: 1.7 million cubic feet
Push to Non-Biocide Paints
AB 425: Leech rates and reformulation recommendations.
Stripping Bottoms to accommodate Non-biocide Paints
BMP’s for Divers
Economic Analysis by RWQCB

14. When you know you need a bottom job!

15. Bottom Paints Basics Biocide Paints: Non-Biocide Paints: Copper
Other metals
Other biocides (Econea, Irgarol)
Non-Biocide Paints:
Hard bottom ceramics or epoxy
Soft bottom silicates (Intersleek)
Slip liners

16. How do Copper Bottom Paints Work?
Cu+ and Cu+2 ion
Self Polishing or Ablative action
Bio-Availability and Toxicity
Total Copper vs Biotic Ligand Model (“BLM”)
Copper is Biocide of Choice!
Kills most invasive species
CA Department of Pesticide Regulation (“DPR”)
AB425 Leech Rates (Category 1,2,3)

17. Issues with Non-Biocide Paints
Increased expense to strip bottom ($8,000 avg)
Increased cost of paint
Require more frequent and more extensive periodic cleaning
Silicate paints are soft and easily damaged-Not long lasting
Ceramic or epoxy paints-Longer lasting but must be cleaned frequently (weekly)
No manufacturer warranty and a signed release required for Hydrosleek by Interlux
Potential increase in transport of invasive species

18. Copper Bottom Stripping
Stripping Bottoms
Copper Bottom Stripping
Copper Waste

19. Slip Liners
Only relocates bio-fouling to the bottom of the liner which will become very heavy and difficult to haul and clean. Also, pesticides used in the liner can be released into the environment and liners are primarily for smaller vessels.

21. Low Copper: Hydrocoat SR on Hatteras after 1.5 years

22. Intersleek 900 Bottom Paint

23. New Ceramic Paint by “HullSpeed. us” applied to Waterkeeper vessel
New Ceramic Paint by “HullSpeed.us” applied to Waterkeeper vessel. Will be monitored for performance by The BoatYard.

24. Prop Speed

25. Three Legs of a Stool
In order for any copper reduction plan to work it must have three solid legs:
Effective Alternatives: Alternatives must be proven to work in the real world and backed up by strong manufacturer warranty
Boater Buy-In: Boaters must believe this is the right thing to do and in their best interest for the benefit of the environment
Cost Effective: The alternative must be cost effective and readily available.

26. Implementation Issues
Designating the County, the Lessees, and Boat Owners as Potentially responsible Parties (“PRP’s”), Citizen Law Suits under CWA
Enforcement Challenges: Transients, work done at other harbors
Selective Enforcement: MDR Only?!
Grants: Sounds good, but….LA County turned down upon first request
Training Divers

27. A Reasonable Approach
1st: Site specific conditions and the adoption of the BLM
2nd: Analysis of real world impacts on bio-availability, and benthic study of indicator species
3rd: Remove or reduce Impaired Waterway designation for marinas. Parking lot for boats analogy.
4th: Cost Benefit Analysis of copper risk vs carbon foot print of dredging
5th: Combination of low copper paints, alternative biocides, and reduction in over-protective threshold can achieve compliance.
