Amendment to Standards and Practices for All Appropriate Inquiries

EPA is taking direct final action to amend the Standards and Practices for All Appropriate Inquiries to reference a standard practice recently made available by ASTM International, a widely recognized standards development organization. Specifically, this direct final rule amends the All Appropriate Inquiries Rule to reference ASTM International's E1527-13 "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process" and allow for its use to satisfy the requirements for conducting all appropriate inquiries under the Comprehensive Environmental Response, Compensation and Liability Act.
