Attendees: Tony Risko, USACE; Kathy Stryker Anderson, USACE; Dennis Eschen, LB Parks, Rec,& Marine; Michael Lyons, LARWQCB; Bill Paznokas, DFG; Susie Ming, Moffatt&Nicol; Chimin Chian, Moffatt & Nicol; Kathryn Curtis, Prt of Los Angeles; Maile Gee, CCC; Dean Smith, LA County; Mitzy Taggart (Heal the Bay)
· Tony Risko, USACE discussed the LA County Regional Dredged Material Management Plan Reconnaissance and Feasibility Study. The technical appendix of the draft August 2000 Recon Study discusses and reviewed potential pilot projects for contaminated sediment disposal alternatives.
· Potential Pilot projects include:
$3.8 million for all four
· Need to coordinate with Regional Water Quality
Control Board
$400,000 free to be used in pilot project. Corps will be getting in October.
Was to go to SCRP for concrete stabilization treatability study.
RWQCB will also be doing a market research study to research the market for
stabilized end product.
· Group brainstorm session on Relationship
between Biological Organisms and Effects of Dredging.
Goal: Develop Best Management Practices for protection of protected/endangered
species
Project Areas

Port of Los Angeles
Port of Long Beach

Dredging Impacts
Noise (humans, birds) -- Excavation (habitat destruction, veg, invert)
Turbidity (humans, veg, fish, bird) -- Resuspension of contaminants (invert,
fish, bird) bioaccumulation
Air Emissions (humans)
Idle Equipment (human, veg, birds) -- Temporary Disturbance of Habitat Areas
(mm, invert,fish, bird)
Pollutant spills (human, invert, mm, Fish, bird)
Debris (human, mm, bird)
Disposal Impacts
Noise (human, bird)
Air Emissions (human)
Turbidity (human, veg, fish, bird) --Full water column
Burial Mound (Invert, veg) -- Habitat destruction
Resuspended Contaminants ((invert, fish, bird)
Temp. Destroyed Habitat Areas (mm, invert, fish, bird)
Pollutant Spills (Human, Invert, Fish, Bird)
Debris (human, mm. Bird)
Daily/Seasonal Activities (relationships)
Breeding
Feeding
Migration
Identify habitat categories
· Review existing biological studies for more precise list
· Match species with impact
· Determine impact threshold
· Corps will be sending out a letter requesting intent (to act as local sponsor for Feasibility Study)
