1.1 Purpose—The purpose of this practice is to define a good practice in the United States of America for conducting a transaction screen2 for a parcel of commercial real estate where the user wishes to conduct limited environmental due diligence (that is, less than a Phase I Environmental Site Assessment). If the driving force behind the environmental due diligence is a desire to qualify for one of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Landowner Liability Protections (LLPs), this practice should not be applied. Instead, the ASTM E1527: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process or ASTM E2247: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property may be used. 1.1.1 This practice will not satisfy the requirement to conduct all appropriate inquiries into the previous ownership and uses of the property consistent with “generally accepted good commercial and customary standards and practices” as defined in 42 U.S.C. §9601(35)(B) to qualify for one of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Landowner Liability Protections (LLPs). Users who desire to conduct environmental due diligence to qualify for one of the CERCLA LLPs should conduct assessment activities in conformity with “Standards and Practices for All Appropriate Inquiries,” 40 C.F.R. Part 312, ASTM E1527: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process or ASTM E2247: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property. 1.2 An evaluation of business environmental risk associated with a parcel of commercial real estate may necessitate investigation beyond that identified in this practice.
