Alternative Ballast Water Exchange Areas Workshop
June 20-22, 2006
Seattle, Washington

Perspectives
California’s Ballast Water Management
for Control of Nonindigenous Aquatic Species Passenger vessels from Mexican ports
• Alternative management as effective as mid-ocean BWE
• Develop plan to compare AEZ with mid-ocean waters
• Involved USCG, scientist, state regulatory agencies
• After 18 months of negotiations study never completed
Alternative request denied
Marine Invasive Species Act Mandates for the Coastal Regulation
P.R.C. Section 71204.5 “…shall adopt regulations governing ballast water management for vessels arriving at a California port
or place from a port or place within the Pacific Coast Region.”
The commission / regulation shall…
“…consider vessel design and voyage duration…”
“…be based on the best available technology economically achievable…”
“…be designed to protect the waters of the state.”
“…include…restrictions or prohibitions on discharge…into areas…shown to have a capacity of retain organisms.”
Development of the Regulation:Workshops and Advisory Groups
2002 WorkshopWest Coast Oceanography: Implications for Ballast Exchange
Avoid “retention zones” (50 nm)
Avoid estuary and river plumes (15 nm)
Avoid waters shallower than 200 m
2003 WorkshopWest Coast Exchange
Participants (50 Total from CA, OR, WA): Maritime Industry, Environmental Groups, Biological Oceanographers, Regulators
Consensus points:
Consistency with federal/international regulations
Safety exemptions
Consider impacts to the merchant industry (economic)
Consider ballast exchange zones
No exchange 200 m or shallower
Should be enforceable, meaningful, and understandable

Exclusion Zones
~=25NM (46.3 km)
~=50NM (92.6 km)
Development of the Regulation:Workshops and Advisory Groups
2004 CSLC Technical Advisory Group MeetingCalifornia Coastal Ballast Water Management
Participants (38 Total from CA, OR, WA): Industry, Regulators, Environmental Groups
Consensus Points
50 nm ballast water exchange
Designation of shared waters
Develop an alternatives process for vessels unable to comply
•2005 California Rulemaking Process
Approved September 23, 2005 Effective March 22, 2006
QUESTIONS/ISSUES
•Biological/physical/chemical composition in AEZs
•Impact of BWE on AEZs
•Risk of onshore transport from discharges at AEZs
•Water movement on, off and along shore
RESEARCH NEEDS
•Chemical/physical/biological parameters?
•Site specificity?
•Local vs. regional vs. national?
•Oceanographic modeling?
MANAGEMENT QUESTIONS/ISSUES
Need to establish AEZOrigin of vessel?
Conditions necessary to utilize AEZ Onus on regulatory or regulated community?
ApplicabilityCalifornia versus West Coast versus National?
ConsistencyExisting state and international requirements
