ASTM Approves New Standard for Environmental Site Assessments

ASTM Approves New Standard for Environmental Site Assessments

The ASTM Committee on Environmental Assessment, Risk Management and Corrective Action (E-50) revised its standard for conducting Phase I Environmental Site Assessments (ESAs)...

On November 1, 2021, the American Society for Testing and Materials (ASTM) Committee on Environmental Assessment, Risk Management and Corrective Action (E-50) revised its standard for conducting Phase I Environmental Site Assessments (ESAs). Phase I ESA’s facilitate commercial property transfers that satisfy the U.S. Environmental Protection Agency (EPA) All Appropriate Inquiries Rule (AAI Rule), as defined by the federal Superfund law (CERCLA), and 40 C.F.R. § 312.11. They also aid in the underwriting of mortgage loans and inform prudent risk management and decision-making. 

Understanding the AAI Process

The AAI process evaluates a property’s environmental conditions and assesses potential liability for any contamination. The 2002 Brownfields Amendments to CERCLA required the EPA to promulgate regulations establishing standards and practices for conducting AAI. The AAI final rule provides that the current versions of ASTM International Standard E1527 “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process” and E2247 “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property” are consistent with the requirements of the final rule and can be used to satisfy the statutory requirements for conducting AAI.

CERCLA provides liability protections for certain landowners and potential property owners who did not cause or contribute to contamination at the property and can demonstrate compliance with specific provisions outlined in the statute, including conducting AAI into present and past uses of the project. AAI requirements specifically apply to any party who may seek to claim protection from CERCLA liability as an innocent landowner, contiguous property owner or bona fide prospective purchaser. Additionally, parties who receive grants under EPA’s Brownfields Program must comply with the AAI rule when using grant funds to assess or characterize properties.

Key Changes to ASTM’s ESA Standard

ASTM’s Phase I Standard was first published in 1993 to define “good commercial and customary practice” for conducting ESAs. The prior version of the standard was incorporated by reference into the EPA’s AAI Rule. Its latest update, known as “E1527-21 – Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,” represents more than three years of ongoing collaboration by more than 150 industry professionals, according to ASTM.

Like its predecessor, the ASTM E1527-21 Standard outlines what constitutes “good commercial and customary practice for conducting an environmental site assessment of a parcel of commercial real estate in the United States of America with respect to the range of contaminants within the scope of the Comprehensive Environmental Response, Compensation & Liability (CERCLA) Act (42 U.S.C. 9601) and petroleum products.” Below is a brief summary of the substantive changes in the updated version:

• Key terminology revisions: The terms “Recognized Environmental Condition” (REC); “Controlled Recognized Environmental Condition” (CREC); and “Historical Recognized Environmental Condition (HREC) have been strengthened to reduce misclassifications of known or likely hazardous material and petroleum product releases affecting subject properties. The revisions are further supported by a new appendix that provides guidance on the REC/HREC/CREC decision process, a flow chart, and representative examples of each.
• New definitions: The terms “Property Use Limitation” (PUL); and “Significant data gap” have been formally defined to provide important clarification of existing concepts. 
• The historical records review section has been restructured and updated to reflect good commercial and customary practice. The revisions clarify subject and adjoining property identification, use, and research objectives; and new parameters have been established for the use of standard historical sources. 
• Detailed site reconnaissance requirements have been added to reinforce existing good commercial and customary practice.
• Revised report requirements have been added to strengthen the deliverable, including consistent use of the term “subject property”; identification of RECs, CRECs, and significant data gaps in the Conclusion section; photos of site reconnaissance items; and a site map.
• Updated appendices: Including an extensively revised legal appendix; new REC/HREC/CREC guidance; revised report outline; and updated discussion of business environmental risks including emerging contaminants.

Implementing the New ASTM E1527-21 Standard

Now that ASTM has approved the ASTM E1527-21 Standard, the EPA must revise the AAI Rule to incorporate the changes. The EPA’s rulemaking process can take up to one year to conclude, which can raise questions about what standard to use in the interim.

The first option is to continue using and citing the ASTM E1527-13 Standard, which is currently incorporated into the AAI. However, buyers, environmental professionals, and others may elect to use the more modern standard, which will likely become compulsory sometime in 2022 in order to satisfy the requirements of the AAI Rule and qualify for the applicable CERCLA defenses. Finally, it is also possible to use a hybrid approach by citing the ASTM E1527-13 Standard, while also stating that the Phase I ESA includes procedures set forth in the new ASTM E1527-21 Standard.

Key Takeaway

The changes reflected in the ASTM E1527-21 Standard will impact how commercial property purchasers and environmental professionals conduct environmental due diligence. We encourage impacted entities to thoroughly review the updated standard and contact a member of the Scarinci Hollenbeck Environmental Law Group with any questions.
