Environmental Due Diligence Services


Meeting environmental due diligence requirements has always been a challenge, and the recent promulgation of new regulations by the United States Environmental Protection Agency (EPA) has added new hurdles. Environmental, Inc. personnel have the extensive experience in compliance with these regulations to assist our clients in efficiently navigating these regulations.

Phase I Environmental Site Assessment (ESA)/EPA All Appropriate Inquiry (AAI) – The EPA established standards and practices for conducting AAIs as required under sections 101(35)(B)(ii) and (iii) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) effective November 2, 2006. ASTM Standard E1527-13, the standard by which Phase I ESAs are conducted, was modified to reflect the adoption of the AAI standard by the EPA. The purpose of the Phase I ESA/AAI reports is to provide you with landowner liability protection under the CERCLA regulation.

The Phase I ESA/AAI investigations consist of an inspection of the site and surrounding properties, a review of available environmental regulatory records for the site and nearby properties, interviews with emergency services personnel concerning reported responses to environmental emergencies in the vicinity of the site, and a review of historical documentation regarding the past ownership and uses of the site and adjoining properties. All Phase I ESA/AAI reports prepared by Environmental, Inc. are in general accordance with the ASTM and EPA standards.

Phase II Environmental Site Assessments – When a source of potential environmental liability is discovered at a property during a Phase I ESA/AAI, additional investigation may be warranted to determine if the potential source of liability has adversely affected soils and/or groundwater at the property. The Phase II ESA typically consists of collection and analysis of soil and/or groundwater samples. Our professional staff can conduct these assessments as necessary; however, it is our philosophy to limit the need for intrusive investigation at the site by conducting a thorough Phase I ESA/AAI investigation and considering potential effects on the property.
