Phase I Environmental Site Assessments Services
Phase I Environmental Site Assessments (ESA) consist of a detailed review of available current and historical records, a visual inspection of the site and conducting interviews to identify potential environmental concerns. Phase I ESAs are conducted following ASTM E1527-05 standards including the new All Appropriate Inquiries (AAI) Rule enacted by the Environmental Protection Agency. The records search includes business licenses, construction permits, phone directories, fire insurance and historical maps, title reports, historical aerial photographs and regulatory agency files. As part of the research, an environmental database covering federal, state and local agency listings is obtained and reviewed to assess environmental uses and concerns at the site and in the vicinity. Neighboring properties are evaluated because of the potential for contamination to migrate across property boundaries in groundwater, surface water or as vapors in soil.
Potential concerns in the Phase I process include ...
Potential concerns in the Phase I process include existing or former underground storage tanks (UST), dry cleaners, chemical storage and handling, wastewater clarifiers, surface staining, PCB-containing equipment, sumps and wastewater clarifiers. Additional concerns are asbestos-containing materials, lead-based paints, lead in water and radon. If significant environmental concerns are identified during the Phase I process, a Phase II assessment is recommended.
ASTM Transaction Screens are limited Phase I ESA designed for small cap loans on sites with minimal or no expected environmental concerns. The transaction screen consists of a site visit, a database records search and completing a site history checklist.
In some instances, the scope of a Phase I ESA is reduced to an update of a recent Phase I ESA or to a desktop review of a recent Phase I ESA report prepared by others to verify conformance with current industry standards.
ASE has prepared a “Due Diligence Short Course for Real Estate Professionals” to assist members of the industry. This course has been presented and distributed to numerous groups of real estate professionals throughout California.
