A Phase I Environmental Site Assessment (ESA), sometimes referred to as a Phase 1 Environmental, is a minimum environmental investigation for a buyer/seller/lender of commercial or industrial property. The ESA allows buyer liability protection under CERCLA known as the “innocent landowner provision”. Guidelines for performance of Phase I ESAs can be found in ASTM E-1527 and the EPA All Appropriate Inquiry (AAI) rule. A Phase I ESA consists of a visual inspection of a property and surrounding area, historical records research, local, state and federal environmental database review, interviews with the owner and occupants of the a property and production of a written report.
Further investigation may be recommended by the Phase I ESA. This investigation may include soil sampling, groundwater sampling, and soil gas/sub-slab soil gas sampling for hazardous substances or petroleum products. Soil and water sampling requires the oversight of a State Registered Professional Geologist. A Phase II ESA will provide a potential lender, property owner, or buyer with information to make an informed business decision regarding the property and mitigate risks.
