On August 15, 2013, the U.S. Environmental Protection Agency (“EPA") published an amendment to the All Appropriate Inquiries Rule that introduces a new industry standard for completing a Phase I Environmental Site Assessment (“Phase I”). A Phase I is an industry-accepted snapshot of a property’s conditions, history, and environmental status that can satisfy the “all appropriate inquiry” requirement of certain defenses to environmental liability, including the bona fide prospective purchaser, innocent landowner, and contiguous landowner defenses under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”). Currently, parties can satisfy the “all appropriate inquiries” requirement by meeting the regulatory requirements in the All Appropriate Inquiries Final Rule (40 C.F.R. 312) or by conducting a Phase I that complies with ASTM E1527-05 Standard Practice for Environmental Site Assessments.  The amended rule will allow—but not require—parties to use a new ASTM standard, E1527-13, to satisfy the “all appropriate inquiries” requirement. ASTM standard E1527-13 is reported to differ from E1527-05 in several important respects and thus raises a host of issues that could impact real property transactions.
The new ASTM standard is not yet available to the public. However, the EPA’s notice of its proposed amendment included a summary of the reported differences between E1527-05 and E1527-13. Some of the most notable differences relate to releases that have been closed by regulatory authorities with contamination remaining in place, vapor intrusion, and agency file reviews. The new standard revises the definitions of “Recognized Environmental Condition” (“REC”), “Historical Recognized Environmental Condition” (“HREC”) and “de minimis condition,” and it adds a new defined term: “Controlled Recognized Environmental Condition” (“CREC”). CREC will describe past releases that obtained regulatory closure but were not cleaned up to unrestricted use standards (i.e., contaminants were left in place after completion of a cleanup). This new category will help ensure that a Phase I does not gloss over the fact that contamination remains on a property and that the landowner may have obligations regarding its management, or that the contamination may limit the property’s current or future use. Under the old standard, these releases were often identified as HRECs or a de minimis condition and not given significant attention during diligence.
The definition of “migrate/migration” has been revised to explicitly include vapor intrusion as a consideration for evaluating RECs. Phase Is conducted under the old standard vary in how they address vapor intrusion, with many reports considering it an indoor air quality issue that was beyond the scope of the Phase I. The new standard also clarifies that non-scope indoor air quality issues differ from vapor intrusion and are limited to conditions unrelated to releases of contaminants. The increased attention to vapor intrusion should align Phase Is with a trend in environmental law to consider and evaluate the effects of vapor intrusion on building occupants.
The new standard also clarifies the requirements for an environmental professional’s agency file review. In particular, environmental professionals should review agency files for adjoining properties identified in the records database report, and a Phase I must justify any decision not to review regulatory records for a site identified in the database report. The delays associated with records requests from some agencies may make it difficult to meet transaction deadlines while conforming with the new standard.
Use of the new ASTM E1527-13 standard should improve the overall understanding of a parcel’s condition, but it may have several adverse impacts in the marketplace, including:
These regulatory and legal uncertainties, and the fact that it is difficult to have any meaningful public input on the rule amendment until E1527-13 is available for public review, make it unlikely that the rule amendment will be “noncontroversial” as the EPA predicts.
The EPA published the rule amendment as a “direct final rule,” which means the rule will take effect on November 13, 2013, if no adverse comments are received by September 16. Comments should reference Docket ID No. EPA–HQ–SFUND–2013–0513, and may be submitted online at www.regulations.gov, via e-mail to
K&L Gates Environmental and Real Estate attorneys will continue to monitor this rule.
Notes: A Phase I conducted in accordance with ASTM E2247-08 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property also satisfies the All Appropriate Inquiries Final Rule.
