“Parthenogenic” means that the unfertilized egg of a female of a given species developsinto a new individual of that species and does not require a male to fertilize the eggs forreproduction.“Pinelands” means any area consistent with the provisions of the Pinelands ProtectionAct, N.J.S.A. 13:18A-1 et seq. and any rules promulgated pursuant thereto, and withsection 502 of the National Parks and Recreation Act of 1978, 16 U.S.C. §4711.“Rare Species” means a group of organisms that is very uncommon or scarce. Thisdesignation may be applied to either a plant or animal taxon, and may be distinct from theterm “endangered" or “threatened species.""Receptor" means any human or other ecological component that is or may be affected bya contaminant from a contaminated site (N.J.A.C. 7:26E-1.8).“Receptor Evaluation” means the general and reporting requirements specified inN.J.A.C.7:26E -1.12 through 1.16.“Receptor Evaluation form” means the form required by the NJDEP pursuant toN.J.A.C.7:26E -1.12 (c) and (e).“Reference Area” means a habitat similar to the habitat being assessed but which is notcontaminated. The reference area may or may not be within the background area."Remediation standards" means the combination of numeric standards that establish alevel or concentration, and narrative standards, to which contaminants must be treated,removed or otherwise cleaned for soil, ground water or surface water, as provided by theDepartment pursuant to N.J.S.A. 58:10B-12, in order to meet the health risk orenvironmental standards (N.J.A.C. 7:26E-1.8).“Riparian” means of, pertaining to, or situated or dwelling on the bank of a river or otherbody of water.“Risk management strategy” or “risk management decision” or “RMD” means a decisionto remediate an ESNR to a level other than the calculated ecological risk-basedremediation goal by taking into account risk reduction, habitat destruction, preservationand restoration, and technical impracticability. A risk management decision may result inremediation to a higher numeric level, which may not be protective of all receptors, topreserve certain habitats that are hard to restore but ultimately results in significant riskreduction.“Saline waters” means waters having salinities generally greater than 3.5 parts perthousand at mean high tide (N.J.A.C. 7:9B-1.4).“Sediment” means unconsolidated material that has been deposited from water and settlesto the bottom of a surface water body or within a wetland.“Sediment pore water” means the water located in the interstitial space between thesediment solid-phase particles.“Sediment quality triad approach” means the use of benthic macroinvertebrate surveys,sediment chemistry and sediment toxicity tests to provide a measure of ecosystem health.Ecological Evaluation Technical Guidance Document 15Version 1.2 8/29/12
“Site investigation” means the collection and evaluation of data adequate to determinewhether or not discharged contaminants exist at a site or have migrated or are migratingfrom the site at levels in excess of the applicable remediation standards. A siteinvestigation shall be developed based upon the information collected pursuant to thepreliminary assessment. The requirements of a site investigation are set forth at N.J.A.C.7:26E-3 (N.J.A.C. 7:26E-1.8)."Surface water" means water defined as surface water pursuant to the Surface WaterQuality Regulations, N.J.A.C. 7:9B (N.J.A.C. 7:26E-1.8).“Taxonomic class” means the group an organism is placed into by the orderlyclassification of plants and animals according to their presumed natural relationshipsbased on similarities of structure, origin, etc.“Technical Impracticability” means a condition where remediation to the applicableNJDEP standards is not feasible from an engineering perspective if: current engineeringmethods or best available technologies designed to meet the applicable standards cannotbe reasonably implemented. TI determinations can be applied to an entire site or a portionthereof. The TI determination does not relieve the responsible party of their ultimateresponsibility of achieving applicable NJDEP standards. If such a determination is made,but subsequent advances in remedial technologies or changes in site conditions makeachievement of the standards practicable, NJDEP reserves the authority to modify the TIdetermination, as appropriate. Impracticability does not equate to “no action.” When aremedial action is deemed impractical, the remediating party must put in place othermeasures to safeguard potential receptors in accordance with N.J.A.C. 7:26E-5.1(e).(NJDEP Technical Impracticability Guidance for Groundwater Document)."Tentatively identified compound" or "TIC" means a non-targeted compound detected ina sample using a GC/MS analytical method which has been tentatively identified using amass spectral library search. An estimated concentration of the TIC is also determined(N.J.A.C. 7:26E-1.8).“Threatened species” means a species that may become endangered if conditionssurrounding it begin to or continue to deteriorate. Thus, a threatened species is one that isalready vulnerable as a result of, for example, small population size, restricted range,narrow habitat affinities, significant population decline, etc.“Toxicity reference value” or “TRV” means a dose above which ecologically relevanteffects might occur to wildlife species following chronic dietary exposure and belowwhich it is reasonably expected that such effects will not occur.“Wetlands” means those areas that are inundated or saturated by surface or groundwaterat a frequency or duration sufficient to support, and that under normal circumstances doessupport, a prevalence of vegetation typically adapted for life in saturated soil conditions.Wetlands generally include swamps, marshes, bogs, and similar areas (40 CFR 230.3).Ecological Evaluation Technical Guidance Document 16Version 1.2 8/29/12
