  1. Environmental Technology Verification ProgramOverview and Ballast Water Treatment and Monitoring Efforts May 1, 2007 Great Lakes Task Force Washington, DC Teresa Harten ETV Director, USEPA, ORD National Risk Management Research Laboratory

  2. ETV Snapshot • Created in 1995 to provide objective testing of commercial-ready environmental technologies • Speeds implementation and helps solve environmental problems • 385 Verifications, 85 protocols completed • Collaboration and privatization: funding from vendors and other partners at over 50% (30% cash and 20% in-kind) • Web and international interest >3M hits/year

  3. ETV Helps Technology Commercialization and Innovation Research Proof of Development Demonstration Verification Commercialization/ Concept Deployment

  4. Example case study: Diesel Retrofit Technologies • 7 tested • 6 eligible for EPA grants program (ex: Clean School Bus) • Minimum 1345 sold as result • At 10% projected market penetration • 9-31K tons PM reduced • $4-15 B in monetary benefits • 680-2400 avoided premature mortality

  5. Currently Six ETV Centers – Two working in Ballast Water • ETV Water Quality Protection Center NSF International • ETV Advanced Monitoring Systems Center Battelle ETV P2 Coatings and Coating Equipment Pilot Concurrent Technologies Corporation ETV Air Pollution Control Technology Center RTI International ETV Drinking Water Systems Center NSF International ETV Greenhouse Gas Technology Center Southern Research Institute

  6. What to Do?

  7. How Do They Get Here ? Thousands of nonindigenous species are transported in ships’ ballast water from one port and released into other ports. Ballast water is required by ships worldwide to: • Maintain waterline & stability during loading & unloading operations • Maintain stability at sea • Aid propulsion & maneuverability • Reduce stress on hull Increased Importance of Ships as Transporters of Nonindigenous Species • Ship size, number of ships, transit speeds, voyage frequency • Combination leads to increase in number, type, vigor of organisms introduced with ballast water

  8. US ETV Ballast Water Monitoring and Treatment • Collaboration with Coast Guard on: Treatment technology - develop and validate testing protocol for technology performance Exchange screening technology – verify technology performance

  9. Coast Guard and USEPA ETV Background • Coast Guard regulates ballast water discharge • 2001 - Coast Guard entered into MOU with EPA ETV to jointly develop testing protocol for ballast water treatment technology • Interagency Agreement funded by Coast Guard at $750K for ETV to develop protocol

  10. Treatment Technology Protocol Development • A draft protocol has been developed (and used as basis of International Maritime Organization recommendations). • A test facility at Naval Research Laboratory in Key West was built per the protocol specifications. • This past winter a technology test was conducted to help validate the protocol.

  12. Ballast Water Treatment Technology Verification One of four zooplankton sampling nets in the 100 m3 ballast tank used to collect organisms after treatment

  13. Ballast Water Treatment Technology Verification Severn-Trent DeNora’s BalPure Ballast Water Treatment System, was selected by the Coast Guard to pilot test ETV protocol. The system is based on an electrochlorination process and is used in both ballasting and deballasting cycles

  14. Treatment Technology Protocol Development, cont. • As result of the test, recommendations for changes to the protocol are currently being developed by a peer review group. • Likely there will be a recommendation from the group to conduct another validation test to finalize the protocol. • Another Coast Guard funded effort (outside of ETV) will help inform final protocol. • University laboratory-based testing of organisms to determine susceptibility to current treatment methods/chemicals.

  15. Ballast Water Exchange Screening Technology Verification Ballast exchange involves back-flushing the tanks and is both a time consuming and dangerous operation. Performing ballast water exchange can de-stabilize a vessel and cause hull stress. Ballast water exchange cannot be performed during conditions of high seas often encountered in North Atlantic routes.

  16. Ballast Water Exchange Screening Technology Verification • Ballast water exchange is the current approach used by ships to reduce introduction of invasive species. • Coast Guard is funding ETV verification of one ballast water exchange screening technology that they are considering for use to monitor whether a ship has exchanged its ballast water. • Report to be complete by end of 2007. • Other commercial-ready technologies are available and could be verified in future.
