Real property transfers typically require Phase I and / or Phase II Environmental Site Assessments (ESA). These assessments are conducted to satisfy the level of appropriate inquiry for the purposes of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) innocent landowner defense. Ranger conducts all Phase I ESA’s in accordance with standards established in “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process”, designation E-1527-93, published by the American Society for Testing and Materials (ASTM). A Phase I ESA includes a title search, a review of applicable state and federal regulatory databases and files, a review of aerial or satellite photography, a review of Sanborn Fire Insurance maps, a site and area reconnaissance, and personal interviews. These steps are taken to provide a reasonable inquiry as to the current and historical conditions of the property and its environs. A report detailing the findings and the estimated potential for impact is subsequently prepared. Depending on the findings, further investigation (Phase II ESA) may be warranted.
Phase II ESAs are generated from available information concerning potential above- or under-ground contamination. Ranger can provide an estimate of potential liability, should a given property be acquired. Ranger collects known information to identify the potential contaminant(s) and designs a sampling plan to assay the applicable medium for the proper constituent(s). This sampling plan may include use of soil-gas analysis, soil and / or groundwater sampling and analysis of unknown container contents for waste characterization. Ranger performs an analysis of the potential threat of impact to human health and the environment by the contaminants. A report detailing assessment findings and potential or current environmental impact is subsequently prepared.
