| •
DTSC Review and Comments |
Specific objectives of
the Preliminary Endangerment Assessment include:
• Determine if a release of hazardous wastes/substances exists
at a site and delineating the general extent of the contamination.
• Preliminary project scoping activities to determine data gaps
and identify possible remedial action strategies to form the basis
for development of a site strategy.
• Determine if an expedited response action is required to
reduce an existing or potential threat to public health
or the environment.
• Estimate the potential threat to public health and/or the
environment posed by the site contaminants and provide
an indicator of relative risk among sites.
• Assess and provide community information needs.
• Provide the data and information necessary to list the site,
if necessary, for inclusion in the DTSC's annual workplan.
If the PEA determines
that a further investigation of the site is not required (i.e.,
is not a significant health risk), a "no further action"
letter will be issued by the Department of Toxic Substance Control
(DTSC). Otherwise, a Removal Action Workplan or Remediation Investigation/Feasibility
Study must follow.
