Environmental Site Assessments

Phase I ESA: A Phase I ESA is an initial inquiry and general review of a defined location to identify potential sites and/or sources of environmental impact and may include:

· Site visit and visual observation.

· Review of past use and history of site.

· Review soil survey histories and geological map.

· Review of adjacent properties.

· Interviews with previous owners, tenants, neighbors, and government officials.

· Review of additional federal, state and local government databases or other records (including permit history and enforcement actions).

· Final report including identification of potential impacted areas, summary conclusions and recommendations.

Phase II ESA: In the event that potential sources of environmental contamination or impacts are identified in the Phase I ESA or other assessments performed, a Phase II ESA outlined in a statement of work serves to confirm or deny the findings.  A Phase II ESA may include:

· Monitoring of site.

· Sampling of materials.

· Laboratory testing and analysis of materials.

· Final report including conclusions and recommendations.

· Assistance with applicable permit applications.

· Assistance with regulatory compliance.

· Liaison service between customer & local, state and/or federal government agencies.

· Training.

Phase III ESA: A Phase III ESA is a post-cleanup assessment to ensure that the environmental impacts identified in previous ESA’s have been properly addressed.  A Phase III ESA may include:

· Review of Contractors cleanup methodology and practice.

· Sampling of materials.

· Laboratory testing and analysis of materials.

· Final report including conclusions and recommendations.

The traditional industry standard for Environmental Site Assessments has been the ASTM-E1527 series.   Recently, the Environmental Protection Agency (EPA) formalized federal regulation—All Appropriate Inquiry with additional legal implications.  By following ASTM E1527-2005 protocol, Castle-Rose warrants that all ESA’s that we perform are fully compliant with both the EPA’s AAI and ASTM standards.

In addition to the ASTM and EPA standards, individual  government agencies, such as the FAA, have established agency-specific protocols.  Castle-Rose will work with each agency to ensure that our ESA’s meet all requirements
