The U.S. Environmental Protection Agency (EPA) adopted a new standard for assessing landowner liability under Superfund or CERCLA (Comprehensive Environmental Response, Compensation and Liability Act).
On December 30, 2013, the U.S. EPA adopted ASTM E1527-13, “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process.” This standard allows parties to comply with the “all appropriate inquiries” rule at 40 CFR 312. The American Society for Testing and Materials issued this standard in November 2013 to improve upon its previous Phase I standard.
Interestingly, the new standard does not replace ASTM E1527-05, so both standards are acceptable. Could be confusing!
