Phase I & Phase II Environmental Site Assessments

 

Industrial Printing Facility, Clackamas County, Oregon

BB&A conducted a Phase I Environmental Site Assessment (ESA) to assess current and future environmental liability associated with the property. This project included assessment of former on-site operations and potential environmental trespass from nearby light industrial and manufacturing facilities.

The results of the Phase I ESA identified several recognized environmental conditions including an on-site release of alcohol from a former underground storage tank (UST), former use of chemicals such as tetrachloroethylene (PCE), 1,1,1-trichloroethane (TCE), isopropyl alcohol, methanol, ethanol, and PCE-containing solutions in on-site operations, and an area-wide presence of trichloroethene (TCE) groundwater contamination. Based on the results of the Phase I ESA, and to limit potential future liability, BB&A recommended that background levels (if any) of contaminants in soil and groundwater beneath the property be investigated prior to the sale or transfer of the property. A subsequent Phase II ESA conducted at the site, which included completion of five (5) push probe borings to allow collection of subsurface groundwater samples, confirmed the presence of PCE, TCE, and related break-down compounds in groundwater at levels exceeding Environmental Protection Agency’s (EPA) Preliminary Remediation Goals (PRGs) and Maximum Contaminant Levels (MCL) for drinking water. Although the sale of the property occurred, the former facility owner was identified as responsible party for future cleanup.
