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; (U.S.) Amy Dindal, Battelle, at +1 (561) 422-0113; or (Canada) John Neate, OCETA, at +1 (905)822-4133 or

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 . 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 more, go to .
