Memorandum of Agreement (MOA):
A written agreement between NJDEP and one or more
persons concerning remedial activities planned for
a site. It is not an enforcement document and does
not require financial assurances or stipulated penalties.
Preliminary Assessment (PA):
Identifies all potentially contaminated areas of concern
(including historic) that will require a site investigation.
Site Investigation (SI):
Determines if any contaminants are present above applicable
remediation standards/ criteria or if no further action
is justified for the areas of concern identified in
the preliminary assessment.
Remedial Investigation (RI):
Entails gathering data necessary to determine the
nature and extent of problems at the site, establishing
the remedial response criteria and identifying remedial
Remedial Action (RA):
The physical action consistent with the selected remedy
to correct a release or threatened release of a hazardous
substance into the environment. The term, often referred
to as a cleanup action or construction project, includes
but is not limited to: confinement, dredging, neutralization,
recycling, removal, reuse and storage or treatment
of hazardous substances. Other actions include providing
alternate water supplies.
Remedial Investigation/Action Workplan:
A detailed schedule and explanation of all investigation
or cleanup activities planned for a site.
No Further Action (NFA)/Covenant Not to Sue:
A determination by NJDEP that, based upon evaluation
of the historical uses and/or investigation of a site
or subsite, there are no contaminants present, or
that any discharged contaminants that were present
at the site or subsite have been remediated in accordance
with applicable regulations.
Classification Exception Area (CEA):
This designation must be established as part of an
approved remedy whenever standards applicable to ground
water in a specific area, which vary throughout the
state, are not or will not be met for the term of
the remediation. The intent of a CEA is to ensure
that the uses of a designated aquifer in a specific
area are restricted until standards are achieved.
Properties must be restricted when contamination will
remain above the residential soil cleanup criteria.
A notice requires a property owner’s concurrence and
documents the location and concentration of all contaminants
and how they must be controlled or maintained and
monitored, if applicable.
Costs incurred and recovered by NJDEP for providing
guidance and approval of privately conducted and funded
remedial activities at contaminated sites.
