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.

1.2 An evaluation of business environmental risk associated with a parcel of commercial real estate may necessitate investigation beyond that identified in this practice. See Sections 1.4 and 11.

1.3 Objective-The objective guiding the development of this practice is to facilitate standardized transaction screens.

1.4 Considerations Beyond the Scope-The use of this practice is strictly limited to the scope set forth in this section. Section 11 of this practice identifies, for informational purposes, certain environmental conditions (not an all-inclusive list) that may exist on a property that are beyond the scope of this practice but may warrant consideration by parties to a commercial real estate transaction. The need to include an investigation of any such conditions in the scope of services should be evaluated based upon, among other factors, the nature of the property and the reasons for performing the assessment (for example, a more comprehensive evaluation of business environmental risk) and should be agreed upon as additional services beyond the scope of this practice prior to initiation of the Transaction Screen Process.

1.5 Organization of This Practice-This practice has several parts and one appendix. Section 1 is the Scope. Section 2 refers to other ASTM standards in the Referenced Documents. Section 3, Terminology, has definitions of terms not unique to this practice, descriptions of terms unique to this practice, and acronyms. Section 4 is Significance and Use of this practice. Section 5 is the Introduction to the Transaction Screen Questionnaire. Section 6 sets forth the Transaction Screen Questionnaire itself. Sections 7 - 10 contain the Guide to the Transaction Screen Questionnaire and its various parts. Section 11 provides additional information regarding non-scope considerations. See 1.4.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
