For further information or to be added to future educational programs invitation lists, please contact Charles E. Michaels at charles.michaels@laaco.net, 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

Bio-Fouling Organisms

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

When you know you need a bottom job!

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

Stripping BottomsCopper Bottom

StrippingCopper Waste

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.

vessel. Will be monitored for performance by The BoatYard.

Prop Speed

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.
