European AdvanceETV Project Solicits Vendors. Environmental Technology
Verification (ETV) programs currently exist in the U.S. and Canada, and a European
ETV scheme is now being established. A European Commission-funded cooperative
project has been launched to develop approaches to facilitate recognition and
acceptance of ETV data among ETV programs. The project, called AdvanceETV, is
currently seeking vendors that would like to have their technologies verified concurrently
in the U.S., Europe, and Canada. The objective is to test candidate technologies once
and the results used to verify in accord with the three ETV programs. Technology
vendors will be required to pay for verification testing for one of the programs.

However, costs for extension to the other two verification programs will be covered by
the AdvanceETV project. These verifications will serve as pilots to propose mutual
recognition processes under the different ETV schemes and, ultimately, for global
recognition. Detailed agreements between candidate technology vendors and the
AdvanceETV partners will be prepared as a first step under this cooperative verification
initiative. Interested vendors should contact one of the following AdvanceETV
partners:(Europe) Christian Gron, DHI, at +45 4516 9570 or chn@dhinmun.com: (U.S.) Amy
Dindal, Battelle, at +1 (561) 422-0113 dindaia@hatteiie.om: or (Canada) John Neate, OCETA,

Framework for Green Cleanup Standards at Contaminated Sites. EPA's cleanup
programs plan to collaborate with ASTM International to develop a green cleanup
standard through a consensus process. EPA worked with its state partners to develop a
draft framework that outlines desired outcomes for a green cleanup standard and will
serve as a starting point for the consensus-based process. The standard will establish
a uniform approach, implemented voluntarily, to encourage property owners,
responsible parties, developers, and communities to use green cleanup practices
during project planning and implementation. EPA is now requesting input from all
stakeholders to enhance the draft framework. The draft framework is available for
review and input through April 30 at httn://clii-in.om/nreenremertiation/suhtah h5.cfm . EPA plans tO
finalize the framework and post it in June 2009. ASTM International established a
subcommittee and will use EPA's proposed framework to kick off the effort. To learn

Natural Attenuation of the Lead Scavengers 1,2-Dibromoethane (EDB) and
1.2-Dichloroethane (1,2-DCA) at Motor Fuel Release Sites and Implications for
Risk Management (EPA 600-R-08-107). The lead scavengers 1,2-dibromoethane
(EDB) and 1,2-dichloroethane (1,2-DCA) were included along with lead in conventional
leaded gasoline used for automobiles in the US prior to 1988. Old spills of leaded
gasoline from underground storage tank systems (USTs) at gasoline service stations
may contaminate ground water aquifers used to supply drinking water. This report is
intended for regulators in the U.S. EPA Regions and in the state environmental
agencies who manage the risk of EDB and 1,2-DCA contamination in ground water.
The report reviews the previous use of EDB and 1,2-DCA in leaded motor fuel,
provides information on the transport and fate of EDB and 1,2-DCA at motor fuel
release sites, and presents results of a study of the current distribution of EDB and
1,2-DCA at motor fuel release sites and the associated chance of contaminating ground
water (September 2008, 74 pages). View or download at

eighteenth annual contract report prepared by researchers from CRREL and other
Federal agencies for the U.S. Army Garrison Alaska, Public Works, describing results of
research, remediation, and monitoring efforts addressing white phosphorus (WP)
contamination in Eagle River Flats, an 865-ha estuarine salt marsh on Fort Richardson,
Alaska. Over the five-year period from 1999-2003, full-scale remediation was
performed at Eagle River Flats using six remote-controlled pumps to temporarily drain
contaminated ponds, allowing the sediments to dry and the WP to oxidize. This effort
successfully remediated about 90% of the ponds. More recently, limited remediation
using one or two pumps has been conducted to address the remaining few
white-phosphorus-contaminated areas (May 2008, 132 pages). View or download at
