Steven Hathaway President, California Yacht Club
Charles Michaels Vice President and General Counsel, LAACO, Ltd.
2. TMDL Overview, Timelines and Goals Charles Michaels
What the Regional Board Wants
What LA County is doing
How Boaters will be affected
Goals for the County, Boaters and Anchorages
3. The BoatYard’s Experience with Cu Paints + Greg Schem
with Frank Szafranski, Key Account Manager, AkzoNobel Yacht Division What Boaters want…and expect How effective are low leach paints? Issues with alternative paints
4. A Boaters’ Experience—The RBOC Perspective Greg Gibeson
Conversations with the State Board AB 425 and the Department of Pesticide Regulation The Biotic Ligand Model and the EPA Boating Update
5. Anchorages: The Marina del Rey Experience Steve Hathaway
Doing what we can now Education, hull cleaning, surveys The Clean Marina Program
6. Many Questions and Some Answers All/Attendees
For further information or to be added to future educational programs invitation lists, please contact Charles E. Michaels at [email protected], or call Lisa Chu at (213) 622-1254.
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 o Use best practices for Hull Cleaning o Use of only Certified Divers o 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
Copper Bottom Paints – A Rational Approach for Marina del Rey
Greg Schem, CEOVictor Espino, Service ManagerHarbor Real Estate Group, LLCMarch, 2015
Bio-fouling over the YearsTechniques of using copper and pitch date back to
1500 BC by Carthaginians and PhoeniciansRoyal Navy adds copper to fleet beginning 1770“Copper-Bottomed”: certain or reliable, trustworthyWhat is a biocide? Pesticide?Iron Hulled Ships, electrolysis issues leads to
development of metal oxide paintsStrong Biocides: TBT, Lead, ArsenicNew Biocides: Non-Copper vs Biocide Free ConfusionEconea, Zinc, Soft bottoms, ultrasound,
nanotechnology
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
Bottom Paints BasicsBiocide Paints:
CopperOther metalsOther biocides (Econea, Irgarol)
Non-Biocide Paints:Hard bottom ceramics or epoxySoft bottom silicates (Intersleek)Slip liners
How do Copper Bottom Paints Work?Cu+ and Cu+2 ionSelf Polishing or Ablative actionBio-Availability and ToxicityTotal Copper vs Biotic Ligand Model (“BLM”)Copper is Biocide of Choice!Kills most invasive speciesCA Department of Pesticide Regulation
(“DPR”)AB425 Leech Rates (Category 1,2,3)
Issues with Non-Biocide PaintsIncreased expense to strip bottom ($8,000 avg)Increased cost of paintRequire more frequent and more extensive
periodic cleaningSilicate paints are soft and easily damaged-Not
long lastingCeramic or epoxy paints-Longer lasting but must
be cleaned frequently (weekly)No manufacturer warranty and a signed release
required for Hydrosleek by InterluxPotential increase in transport of invasive species
Slip LinersOnly 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.

New Ceramic Paint by “HullSpeed.us” applied to Waterkeeper
vessel. Will be monitored for performance by The BoatYard.
Three Legs of a StoolIn 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.
Implementation IssuesDesignating 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 requestTraining Divers
A Reasonable Approach1st: Site specific conditions and the adoption of the
BLM2nd: Analysis of real world impacts on bio-
availability, and benthic study of indicator species3rd: 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.
