Phase I ESA
The Phase I ESA is a preliminary site evaluation used to develop an
understanding of past activities at a site through a review of historical
information about the site and a thorough physical inspection of the site.
Interviews of owners and operators at the property are also conducted.
The purpose of the Phase I ESA is to identify recognized environmental
conditions on the property. Under ASTM E1527-05, recognized environmental conditions are defined as the presence or
likely presence of any hazardous substances or petroleum products on a property
under conditions that indicate an existing release, a past release, or a
material threat of a release.
We also comply with the EPAs All Appropriate Inquiry requirements.
Soil and water sampling is typically not
included in a Phase I ESAthe purpose of a preliminary assessment is, after
all, to determine whether such sampling is necessary. It is often
cost-effective, however, to perform asbestos or lead-based paint sampling at
the same time as the Phase I ESA. Lenders will often require these surveys be
added to the Phase I scope of work when older buildings are present on the
Phase II ESA
A Phase II ESA further investigates recognized
environmental conditions identified in the Phase I report. This may involve
soil or groundwater sampling, dye tests of drains with unknown discharge
points, or other investigation of issues raised in the Phase I.
If required, corrective action plans can be
developed to resolve the environmental condition. Budgets for cleaning up the
site and complying with regulations can then be prepared.
