“Ecological risk-based remediation goal” means risk-based numeric criteria that arecalculated based on site conditions and ecological receptors observed or expected to bepresent at the site. Remediation goals are the preliminary standards developed once it isdetermined that remediation is required within an ESNR.“Ecological screening criteria” or “ESC” means literature values for individualcontaminants that were usually derived by dosing experiments and that are mainly basedon the no observed adverse effect level (NOAEL) or lowest observed adverse effect level(LOAEL). The ESC are generally conservative levels designed to protect the targetorganisms based on direct exposure.“Ecotoxicological effect” means any adverse acute or chronic effect from contaminantson invertebrate, plant, fish or wildlife individual, population, or community.“Endangered Species” means a plant or animal species whose prospects for survivalwithin the state are in immediate danger because of one or several factors such as loss ordegradation of habitat, overexploitation, predation, competition, disease or environmentalpollution, etc. An endangered species likely requires immediate action to avoid extinctionwithin New Jersey."Environmental medium" means any component such as soil, air, sediment, structures,ground water or surface water (N.J.A.C. 7:26E-1.8)."Environmentally sensitive natural resources" means all areas defined at N.J.A.C. 7:1E-1.8(a), ground water, and areas and/or resources that are protected or managed pursuantto the Pinelands Protection Act, N.J.S.A. 13:18A-1 et seq. and the PinelandsComprehensive Management Plan, N.J.A.C. 7:50 (N.J.A.C. 7:26E-1.8).“Epibenthic” means living and feeding on top of the sediment, but may be hidden byleaves and organic detritus.“Estuary” means a tidally influenced area where freshwater inputs from rivers, streams orother conveyances enter coastal marine environments.“Fecundity” means the capacity, especially in female animals, of producing young inabundance.“Feeding guild” means a group of unrelated species that feed on similar foods (e.g.,benthivore, detritivore, herbivore, insectivore, omnivore, planktivore, piscivore), or thetypes of food that an individual organism feeds upon.“Fresh water(s)” means all nontidal and tidal waters generally having a salinity, due tonatural sources, of less than or equal to 3.5 parts per thousand at mean high tide (N.J.A.C.7:9B-1.4).“Geographic Information System” means a computer system for capturing, storing,checking, integrating, manipulating, analyzing, and displaying data related to positions onthe earth's surface."Ground water" means the portion of the water beneath the land surface that is within thezone of saturation where all pore spaces of the geologic formation are filled with water(N.J.A.C. 7:26E-1.8).Ecological Evaluation Technical Guidance Document 13Version 1.2 8/29/12
“Hazard quotient” or “HQ” means the ratio of the results of the measured or modeleddietary contaminant doses to receptors of concern to the toxicity reference value."Historic fill material" means non-indigenous material, deposited to raise the topographicelevation of the site, which was contaminated prior to emplacement, and is in no wayconnected with the operations at the location of emplacement and which includes,without limitation, construction debris, dredge materials, incinerator residue, demolitiondebris, fly ash, or non-hazardous solid waste. Historic fill material does not include anymaterial which is substantially chromate chemical production waste or any otherchemical production waste or waste from processing of metal or mineral ores, residues,slag or tailings. In addition, historic fill material does not include a municipal solid wastelandfill site (N.J.A.C. 7:26E-1.8).“Homolog” means one of a series of congeners with the same number of chlorine atoms.“Inhibitory concentration” or “IC” means the test concentration that yielded an inhibitoryeffect on a given percentage of the exposed organisms.“Lentic” means the ecosystem of a lake, pond or swamp.“Lotic” means the ecosystem of a river, stream or spring.“Lowest observed adverse effects level” or “LOAEL” means the lowest level of exposureof an organism, found by experiment or observation, at which there is a biologically orstatistically significant increase in the frequency or severity of any adverse effects in theexposed population when compared to its appropriate control.“Lowest observed effect concentration” or “LOEC” means the lowest test concentrationat which a significant reduction in survival, growth, or reproduction/fecundity ascompared to the laboratory control or reference sample was observed.“Measurement endpoint” means a measureable response to a stressor that is related to thevalued characteristic chosen as the assessment endpoint.“Method detections limit” or "MDL" means the minimum concentration of a substancethat can be measured and reported with a 99 percent confidence that the analyteconcentration is greater than zero and is determined from the analysis of a sample in agiven matrix containing the analyte (N.J.A.C. 7:26E-1.8).“Mixing zone” means the area of a tidal water body of a site or contaminant source wherethe tidal action is capable of transporting sediment or contaminants within that reach.“No observed adverse effect level” or “NOAEL” means the level of exposure of anorganism, found by experiment or observation, at which there is no biologically orstatistically significant increase in the frequency or severity of any adverse effects in theexposed population when compared to its appropriate control.“No observed effect concentration” or “NOEC” means the highest test concentration atwhich there is no statistically significant reduction in survival, growth, orreproduction/fecundity as compared to the laboratory control or reference sample.“Non-targeted compound" means a compound detected in a sample using a specificanalytical method that is not a targeted compound, a surrogate compound, a systemmonitoring compound or an internal standard compound (N.J.A.C. 7:26E-1.8).Ecological Evaluation Technical Guidance Document 14Version 1.2 8/29/12
