ASTM issues revised standard on phase I environmental site assessments
ASTM has issued revised standard ASTM E1527-13 that governs phase I environmental site assessments. The EPA uses the ASTM standard to determine whether companies have met the “All Appropriate Inquiry” requirement under the Superfund law. The agency is expected to rule by the end of the year on whether both 1527 versions, 2005 or 2013, will be acceptable for that purpose. Until the EPA officially adopts the new standard, companies should continue to follow the 2005 version to meet the AAI requirement.
