Remedial Priority Scoring SystemGlossary
- Classification Exception Area (CEA) - A designation established
whenever ground water standards in a particular area are not met.
It is intended to ensure the use of the ground water in that area is restricted
until standards are achieved.
- Deed Notice - A notification added to the title of a property
when contamination will remain above NJDEP's residential/unrestricted
soil remediation standards, N.J.A.C. 7:26D. A Deed Notice requires
a property owner's concurrence and specifies the location
and concentration of all contaminants and how they must be controlled,
maintained or monitored. Every two years, the party responsible
for conducting the remediation must certify the remedy continues
to be protective.
- Direct Department Oversight - Under certain conditions
or circumstances, as outlined in N.J.S.A. 58:10C-27,
the department shall review each document submitted by an LSRP
and approve or deny each submission. The Department shall also
select the remedial action for the site and require a remediation
trust fund be established in the amount of the estimated cost
of the cleanup. Go to the attached link for a full list of conditions
and requirements relating to this subsection.
- Ecological Health Receptor - Ecological areas represented
by GIS Layers used to determine potential impact on the surrounding
ecological environment. This does not include human health exposure.
- Exceedance Quotient (EQ) - is a normalized value that
enables SRP to compare analytes with different properties and
different concentrations across distance and time. Each analyte
that is sampled will be converted into an EQ. More information
on the Exceedance Quotient can be found in the Basis and Background document.
- Extent Area - The potential area of contamination
at or surrounding the site. The RPS uses this area to evaluate
the relationship between a site and the surrounding environment.
If no data is available, a surrogate extent area is created based
on an analysis of classification exception areas (CEAs) for sites
of similar nature within an operational unit (eg. ISRA, BUST).
- Feedback Loop - A short term mechanism used to gather
information from responsible entities to update the data used
that will be used in the RPS model, which will be published in
the Fall of 2012.
- Geographic Information System (GIS) - is a computer application
that is used to store, analyze and display geographically referenced
data. GIS is the merging of cartography, statistical analysis,
and database technology.
- Ground Water Quality Standards (GWQS) - Standards that
specify quality criteria and designated uses for ground water
for the purposes of remediation of contaminated sites.
- GIS Layers - is a wide variety of spatial data which includes
but are not limited to census data, municipal well locations,
mapping of lakes, streams, wetlands, schools and other significant
- Haz Site/Compass- An internal SRP database that stores
all analytical data that has been submitted electronically to
the Department (http://www.state.nj.us/dep/srp/hazsite/).
- Human Health Receptor - Human population areas
represented by GIS layers used to determine impact on the surrounding
human population via ingestion, inhalation and dermal exposures.
- Immediate Environmental Concern (IEC) - A condition at
a contaminated site where people are exposed to contamination
at levels that exceed applicable screening levels or standards.
- Jenk's Natural Breaks - a data classification method
designed to place values into the best arrangement of different
classes. This is done by seeking to minimize each class's
average deviation from the class mean, while maximizing each class's
deviation from the means of the other groups. In short, it groups
sites with similar characteristics together and conversely separates
sites with dissimilar characteristics into separate categories.
The RPS Model uses Jenk's Natural Breaks to assign an RPS
Category to a site. More information can be found in the Basis
and Background document.
- Known Contaminated Site List - A report that includes
a listing of: "Active Sites with Confirmed Contamination",
"Pending Sites with Confirmed Contamination", and
"Closed Sites with Remediated Contamination"
- New Jersey Environmental Management System (NJEMS) -
The NJDEP's department-wide enterprise database system that
integrates all data related to its regulated activities for the
purpose of sharing and reporting data, improving workflow and
business practices, and making better environmental decisions.
NJEMS stores, tracks and reports data related to all certifications,
registrations, permits, cases, inspections, violations, and enforcement
actions as well as assessments and collections. It is also a repository
for documents submitted to and created by NJDEP.
- Parcel - Lot and block of a property.
- Pathway Value - is the potential routes contaminants
can travel to expose a person or the environment. A value of 0
is applied if there is no exposure and a value of 1 is applied
if there is potential for exposure.
- Receptor Score - a calculated value that represents the
sum of all the receptor layer values evaluated by the model.
- Remedial Priority System - The Remedial Priority Scoring
System is a computerized model designed to help the Department
to categorize contaminated sites based on potential risk to public
health, safety or the environment as well as other relevant factors
deemed appropriate by the Department.
- RPS Ecological Health Score - is a single value which
represents the impact of the site on potential Ecological Health
Receptors. This is determined by the Ecological Receptor Score
multiplied by a Pathway Value.
- RPS "flags" - A RPS designation that qualifies
additional information related to the Site. Several flags identify
specific chemicals as mandated by SRRA (chromate, polychlorinated
biphenyl, mercury, arsenic and dioxin). Other flags identify specific
conditions at a site such as IECs, Compliance, etc.
- RPS Categories - Grouping of sites with similar
characteristics which are then assigned to categories 1-5. Jenk's
Natural Breaks is the methodology used to determine the categories.
These five categories represent the potential risk assigned to
these sites. Category 1 represents the lowest potential risk through
Category 5 which represents the greatest potential risk. There
is separate Human Health Score and a separate Ecological Health
- RPS Human Health Score - is a single value which
represents the impact of the site on potential Human Health Receptors.
This is determined by the Human Health Receptor Score multiplied
by the Site Condition Score multiplied by a Pathway Value for
each media (water, soil and vapor) which are then summed to produce
the value for each site.
- Site Condition Score - is a single value which represents the site by the
type and extent of contaminants present at the site.
- Unregulated Heating Oil Tanks - Underground and
above ground storage tanks containing heating oil for on-site
consumption in a residential building, or tanks with a capacity
of 2,000 gallons or less for on-site consumption in a nonresidential
