technologies
Mandates
• Protect beneficial uses
• Consult with USCG, Water Board,
Technical Advisory Group

Agreement and Disagreement


Agreement
 Concentration-based
standards over percent
reduction
 Much better than BW
exchange
 Standards should drive
technologies, not the reverse
 Need a finite implementation
schedule
Disagreement
 Numeric values for standards

Performance Standards Report


Presented to Legislature January 2006
Recommendations included:
 Adopt Interim Performance Standards and
Implementation Schedule (as presented by Panel
Majority in report)
 Adopt Final Performance Standard (zero detectable)
 Require initial and periodic review of treatment
technologies
 Grandfather vessels with existing CSLC or USCGapproved experimental technologies
 Consider incentives to promote continued technology
development
Coastal Ecosystems
Protection Act Requirements
 Implementation
of performance standards
for the discharge of ballast water (as
specified in the Performance Standards
Report)
 Report assessing efficacy, availability and
environmental impacts, including water
quality, of currently available
ballast water treatment
technologies
Performance Standards Regulation





Standards prescribed by
statute
Comments/objections
from industry focused on
standards themselves
Approved October 2007
Effective January 1, 2008
Text of regulation
available on CSLC
website
Technology Assessment Report

Key components:




Efficacy
Availability
Environmental impacts, including water quality
If technologies to meet the standards are
unavailable – why not?
 Approved by Commission on December 3
 Due to Legislature by January 1
 Similar reports due 18 months prior to each
implementation date
Information Gathering for Technology
Assessment Report
search – scientific
literature, white papers,
gray papers, promotional
materials
 Discussions with technology developers
 Technical workshop – May, 2007 in Boston
 Advisory panel meeting – October, 2007 in
Sacramento
 Literature
Treatment Technologies/Methods


Shipboard vs. Shoreside
Mechanical – filtration, hydrocyclonic separation,
filtration medium
 Chemical (biocide)




oxidizing (Cl, ClO2, ozone, bromine,
hydrogen peroxide, peroxyacetic acid)
non-oxidizing (Acrolein™, glutaraldehyde,
menadione/SeaKleen)
Physical – UV, heat, ultrasound
Combination – deoxygenation, electrolytic
oxidation (physical + chemical)
Treatment Systems



Information collected on 28 systems
9 countries
17 systems use two or more treatment methods
(often mechanical separation + secondary
method)
 Four main types systems:

Oxidants/oxidative technologies (18)
• Electrochemical oxidation (7),
Cl/ClO2 (6), Ozone (4), Ferrate (1)



UV (4)
Deoxygenation (3)
Other (3)
Efficacy





Results of system efficacy only available for 20
(of 28) systems
Lenient review of results by Staff –
demonstration of “potential” for compliance
Evaluation difficult due to variable testing
methods and results in metrics inconsistent with
standards
Only 11 systems tested onboard vessels
No single technology has yet demonstrated
capability to meet more than four (out of 7) of
California’s performance standards

Availability



Many systems will be
commercially available by
2009
Lack of federal standards
& system approval
mechanisms may be
hindrance to market
demand
Because no single
system meets CA
standards, none truly
available at this time
Environmental Impacts

21 of 28 systems use biocide/active substance
and will require toxicological testing and analysis
 Several systems have been evaluated and
approved for use by International Maritime
Organization (IMO) and State of Washington


Preliminary guidance as to system acceptability
No evaluation procedure in CA yet
 Commission Staff working with SWRCB and
RWQCB to identify applicable water quality
controls plans and regulations

Conclusions
 Current
lack of efficacy and environmental
testing and evaluation procedures makes
it unlikely systems will be available by
2009
 Commission staff will continue to gather
information on and support research
addressing technology development and
system evaluation
 Systems will meet CA standards in future
Recommendations to the Legislature
 Change
initial implementation date for new
vessels with a ballast water capacity less
than 5000 metric tons from 2009 to 2010
 Authorize the Commission to
amend reporting requirements
via regulations
 Support continued research
promoting technology
development
Looking Forward

Treatment system testing and evaluation
guidelines
 Protocols and criteria for verification of
compliance with performance standards
 Work with SWRCB to identify applicable
water quality requirements
 Support alignment of testing and evaluation
guidelines along the West Coast
Testing Guidelines
 Recommended
testing guidelines instead
of CSLC-approval of systems
 Self-certification procedure for use by
technology developers and 3rd party
independent testing labs
 Should reduce use of tests inconsistent
with California standards
 Will be made available to industry in late2008
Compliance Verification Protocols
 Procedures
to verify vessel compliance
with discharge standards
 Detailed protocols – how to sample, where
to sample, chain of custody, labs to
conduct analysis, fees for testing,
timeframe
 Plans to complete regulatory process by
late-2008
The Process

Technical advisory panel meeting beginning in
January 2008
 Two main components: administration and
technical aspects
 Work with USCG to standardize assessment
methods as much as possible with future federal
program
