Phase I Environmental Site Assessments (ASTM E1257-13 or E2247-08 for forestland or rural properties)

By completing a Phase I Environmental Site Assessment (ESA) before purchasing a property, the buyer qualifies for Landowner Liability Protection under CERCLA. The object of a Phase I ESA is to identify any recognized environmental conditions associated with the property. This is completed through interviews, records review and site reconnaissance. At the conclusion of the Phase I ESA, IGI will provide you with a detailed report of our findings that allows you to make an informed decision regarding your property acquisition. The Phase I ESA satisfies the requirements of USEPA’s All Appropriate Inquiry Final Rule, 40 CFR Part 312.

Phase II Environmental Site Assessment [ASTM E1903-11]

If a recognized environmental condition is identified during the Phase I ESA, a Phase II ESA may be conducted to evaluate the recognized environmental condition. The purpose of the Phase II ESA is to provide sufficient information regarding the nature and extent of contamination so that you can make an informed business decision about the property, and also to provide the level of knowledge necessary to qualify for Landowner Liability Protection under CERCLA. The Phase II ESA is a custom investigation that focuses specifically on the recognized environmental conditions identified during the Phase I ESA.

Phase I or Phase II Environmental Site Assessments for SBA Loan Program [SOP 50 10 5 (E)]

If you are in the U.S. Small Business Administration (SBA) loan program, IGI will complete a Phase I or Phase II ESA that meets the requirements of both ASTM E1257-13 and SOP 50 10 5(E).

Transaction Screen (ASTM E1528-06)

In selected circumstances, a buyer may only wish to complete “limited” environmental due diligence. A Transaction Screen identifies potential environmental concerns associated with the property through the completion of a questionnaire, limited records review and limited site reconnaissance.

It is important to understand that a Transaction Screen is not as thorough as a Phase I ESA and does not provide Landowner Liability Protection under CERCLA.

Vapor Encroachment Screening (ASTM E2600-10)

The purpose of Vapor Encroachment Screening (VES) is to identify the likely presence of contaminant vapors in the subsurface. VES is most often completed as part of a Phase I ESA but can be completed as a standalone investigation, if needed.
