On December 30, 2013, the United States Environmental Protection Agency (“EPA” or the “Agency”) approved the recent American Society for Testing and Materials (“ASTM”) Standard E1527-13 as sufficient to satisfy All Appropriate Inquiry (“AAI”) for potential liability protections under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). 78 Fed. Reg. 79,319. As a result, E1527-13 now stands as the baseline for Phase I Environmental Site Assessments (“Phase I ESAs”) and any individuals performing Phase I ESAs should ensure that their assessments are in compliance with that standard going forward.
