Jenner & Block's Corporate Environmental Lawyer is pleased to present a guest blog prepared by John Claypool, Director of Project Management at Brown and Caldwell. Brown and Caldwell is a national engineering consulting firm focused on the U.S. environmental sector. The degree to which and manner in which these ASTM standards are incorporated into regulatory standards is an important topic and we appreciate Brown and Caldwell's insight on this topic.

EPA recently issued a direct final rule to amend the requirements for conducting All Appropriate Inquires (AAI) to qualify for the Bona Fide Prospective Purchaser (BFPP) defense under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). The direct final rule allows for the use of ASTM International E2247-16, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property. When the final rule becomes effective on September 18, 2017, ASTM E2247-16 can be used to satisfy the statutory requirements for conducting AAI.

Since 2008, the AAI rule at 40 CFR Part 312 has allowed the use of E2247-08 on transactions involving forestland or rural properties. As part of its 5-year review and reapproval cycle, ASTM International made significant changes to E2247-08 and reapproved/reissued it under the E2247-16 designation. A summary of the differences between E2247-08 and E2247-16 is available in the USEPA rulemaking docket (Docket EPA-HQ-OLEM-2016-0786).

The revisions to the AAI rule published in the Federal Register on June 20, 2017 allow the use of E2247-08 and E2247-16 for conducting AAI on forestland and rural property. Since E2247-08 is no longer considered an active standard by ASTM International, the practical implication is that AAI for forestland and rural properties will henceforth be conducted per E2247-16. The direct final rule did not make any changes to the AAI requirements for other types of properties, continuing to allow the use of ASTM E1527-13, Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process.

This addition of E2247-16 to the AAI rule may impact both public and private parties intending to claim a limitation on CERCLA liability in relation to the purchase of large tracts of forested land or large rural property. It may also impact parties conducting site characterizations or assessments on large tracts of forested land or large rural properties, when the parties are intending to use a brownfields grant awarded under CERCLA Section 104(k)(2)(B)(ii), including state, local, and tribal governments receive brownfields site assessment grants.

Brown and Caldwell's John Claypool, Brent Callihan and Julie Byrd contributed to the development of the revised ASTM standard, submitting comments to ASTM that led to the development of a working group to revise the standard, ultimately leading to the revised AAI rule.
