Type
|
General Premise
|
Rational for Employing
Specialty Expertise
|
|
Activate or force remediation
|
PRP is recalcitrant and citizens and environment are at risk
|
Identify and describe nature and magnitude of related environmental threat
|
|
Conduct of Remediation;
Completeness of Remediation
|
Regulatory disagreement with assessment of site threat, cleanup plan, or progress of remediation
|
Identify and describe nature and magnitude of related environmental threat, in terms of short-fall in scope of remediation advocated by regulatory agency
|
|
3rd Party
Intervenors in
Disagreement
|
Site/waste characterization is
inadequate and/or flawed and that
remediation underway is inadequate
|
Evaluation of reported characterization findings in terms of opposing technical knowledge
|
|
Regulatory Agency
Seeks Cost Recovery
|
Agency has had to move on
remediation without participation of PRP
|
Prove time-and-place connection between RPP and the UHWS; often the case with off-site dumps or discharges of gas manufacturing residuals or wastes
|
|
Innocent Land Owner Purchases
Contaminated Dump Ground
|
Gasworks wastes transported from the plant and dumped at a remote area; later urbanization creates value for the site and development ensues
|
Developer becomes liable for costs of removal and other forms of site remediation; engages experts to identify the gasworks source and to support litigation for cost recovery
|
|
Health Impairment from
Long-Term Exposure to
PAHs
|
Individuals or clusters of workers
or site or bordering residents have
been subjected to long-term
exposures to PAH carcinogens, from
undeclared wastes
|
Search for, define, and prove presence of otherwise unreported hot spots of wastes or
contaminated soil or water; with linkage to
history of facility operation and its waste
management practices
|
|
Inverse Condemnation
of Real Property Values
|
Presence of facility wastes and/or conduct of remedial actions has caused depreciation of real property
|
Locate and prove presence of migrated plant toxics and of relative effect of the RP remedial actions to date
|
|
RP seeks Recovery of
Remedial Expense from its
Rate Payers
|
That remedial expenses are linked to current service, rather than to past waste management practices
|
Attempt to show that historic practices were proper and in accordance with state of knowledge of the manufactured gas industry, as related to known ground conditions at the present time.
|
|
RP seeks
recovery of
expense from
other PRPs
|
For companies of multi-ownership corporate history, earlier owners or operators are sought for reason of their involvement in generation and/or discharge of toxic wastes
|
Need to identify and demonstrate manner in which the earlier owner is involved; usually involves history of FMGP, its manner of operation, location and extent of toxics, and timing of release and/or transport
|
|
RP seeks
recovery of
expense from 3rd party
|
Some 3rd party has had incidental involvement in generation and/or discharge of toxic wastes
|
Need to identify and demonstrate manner in which the 3rd party is involved; usually involves history of FMGP, its manner of operation, location and extent of toxics, and timing of release and/or transport
