In its draft report it has been working to identify key areas for improving knowledge, methodologies, practice, and research. The committee has focused on EPA needs for valuation in the following areas: national rulemaking, site-specific decision-making, and valuation for use in regional partnerships. It has reviewed a range of EPA analyses supporting those needs and has assessed approaches and methods that offer promise for EPA's use.
