## Abstract

EPA is taking 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, EPA is amending the All Appropriate Inquiries Rule to reference ASTM International's E2247-23 "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property" and allow for its use to satisfy the requirements for conducting all appropriate inquiries under the Comprehensive Environmental Response, Compensation, and Liability Act. In addition, EPA will remove after one year, from the All Appropriate Inquiries Rule, recognition of the previous version of that standard, ASTM E2247-16, as compliant with the All Appropriate Inquiries Rule.
