The ASTM E1527-05 Standard for Phase I Environmental Site Assessments has been accepted by the EPA as meeting the requirements of All Appropriate Inquiry. The latest revisions to the ASTM E1527 were done in 2005, and in 2012 the standard is currently under review for another round of potential changes. The Phase I Environmental Site Assessment scope of work is not anticipated to change dramatically and many of the potential changes serve simply to clarify language. However several potential changes could impact the way Phase I ESAs are conducted or written.
For example, a potential new category of Recognized Environmental Condition (REC) has been proposed: the Controlled Recognized Environmental Condition (CREC), which would apply to risk-based closures of contaminated sites. If adopted, this new term would impact the way findings and conclusions are discussed in the Phase I ESA Report, and could potentially impact the report user’s understanding of environmental risk. Certainly the term would require some education of the industry.
Another potential change to the Phase I Environmental Site Assessment process is an explicit requirement for regulatory file reviews on adjacent properties. Many environmental consultants already perform these file reviews during the Phase I ESA when deemed appropriate due to high risk information being identified at the adjacent properties (such as a leaking gas station). However, an explicit mandate for these file reviews could impact the cost and timing of the Phase I Report, as well as the environmental consultant’s liability.
A decision will have to be made in 2013 whether to adopt any changes to the E1527 standard, or renew the standard as is.
