Environmental Site Assessment & Remediation Services
Cornerstone's Phase I Environmental Site Assessment (ESA) protocol satisfies the requirements of the American Society for Testing Materials (ASTM) Standard Practice for Phase I Environmental Site Assessments (E1527-00). The purpose of a Phase I ESA is to identify, to the extent feasible, Recognized Environmental Conditions (REC's) in connection with a site.
The Phase I ESA will provide a professional opinion as to the potential for contamination from hydrocarbon or hazardous waste to exist, which may require remedial action. The Phase I ESA includes the following general scope of work.
- A physical inspection of the site for surface conditions and potential environmental problems or suspect contamination areas (e.g. evidence of past filling activity, partially buried metal or other debris, discolored pavement or stressed vegetation, unusual odors, wells, vent pipes, fill pipes, dispensing equipment, or other signs of above- or below-grade fuel or chemical tanks, chemical storage, spill control containment devices, septic tank drain fields, transformers and other electrical equipment which may contain PCBs). The site inspection typically includes a visual inspection of the interior of any structures on the site including maintenance/repair areas, storage areas, and a representative sample of occupant spaces. Conditions of adjoining properties, to the extent they can be observed from the site, are also noted.
- A review of available property records and/or other information to establish past land usage. Information including ownership records, Sanborn maps, USGS and Soil Conservation Service publications, aerial photographs, and prior environmental assessment are reviewed if available. Topographic, geologic, hydrogeologic, and hydrologic information is also reviewed.
- Interviews with property owners, occupants or other key site managers are conducted to obtain information about uses and conditions at the site.
- A review of available information and data from Federal, State and local sources as to listings under CERCLA, FINDS, ERNS, RCRA, UST, LUST and other federal or state programs for the ASTM-specified vicinity in which the site is located.
A report is prepared to document the physical conditions observed, a site plan detailing significant conditions, and conclusions including a statement of likelihood of the site being affected by REC's. If pertinent, recommendations for further exploration or remediation for those conditions are provided.
In most cases, a Phase I ESA requires three weeks to complete. However, should you require a quicker turn-around time, we will work to meet your deadline . However, we will not take on a project we can not complete within the proposed time-frame. The cost for conducting a Phase I ESA varies depending upon a number of factors such as property use and size, prior land use and location.
Unless specifically requested, the Scope of Services for the Phase I ESA does not include assessment for mold, asbestos, lead-based paint, radon, formaldehyde, wetlands, lead-in-drinking water, or other testing. However, Cornerstone will provide these services upon request.
