Executive SummaryThis document provides technical guidance on how to conduct an Ecological Evaluation(EE) and an Ecological Risk Assessment (ERA) pursuant to N.J.A.C. 7:26E-1.16andN.J.A.C. 7:26E-4.8 for environmentally sensitive natural resources (ESNR) associatedwith contaminated sites. Guidance is also provided for the derivation of site-specificecological risk-based remediation goals and Risk Management Decisions (RMD).Although the Licensed Site Remediation Professionals (LSRP) should understand thepurpose and intent of this guidance, the investigator performing the EE and ERA must beexperienced in the use of techniques and methodologies for conducting ERAs (C.58:10C-16 (c))and must be able to comply with appropriate guidance including, but not limitedto, USEPA’s Ecological Risk Assessment Guidance for Superfund, Process for Designingand Conducting Ecological Risk Assessments, EPA 540-R-97-006, Office of Solid Wasteand Emergency Response, Washington, DC (ERAGS - USEPA, 1997a) (N.J.S.A.58:10B-12). If the LSRP does not possess the necessary qualifications, subcontracting toqualified investigators is appropriate. This guidance was prepared in accordance with theTechnical Requirements for Site Remediation, N.J.A.C. 7:26E, the Site RemediationReform Act, N.J.S.A. 58:C-1 et seq. and the Administrative Requirements for theRemediation of Contaminated Sites, N.J.A.C. 7:26C.The EE is conducted to examine the site for the co-occurrence of the following:(1) ESNRs on, adjacent to, or potentially impacted by the site,(2) the presence of Contaminants of Potential Ecological Concern (COPEC) at thesite or Area of Concern (AOC) and in the ESNRs, and(3) the presence of a contaminant migration pathway (historic or current) from thesite to the ESNR or evidence of contaminated material having been placeddirectly into an ESNR.The outcome of the EE will be a recommendation either to conduct an ERA or no furtherecological evaluation.The ERA is a quantitative assessment of the actual or potential impacts of COPECs froma contaminated site on wildlife and plants. The ERA consists of the following:(1) rigorous site-specific biological tests, determining whether actual or potentialecological risks exist at a site,(2) identifying whether remediation is necessary for constituents posing ecologicalrisks, and(3) generating data needed to determine site-specific risk-based remediation goals andRMDs.Technical consultation sessions with New Jersey Department of EnvironmentalProtection (NJDEP) staff are available to the LSRP to discuss specific technical issuesrelated to site remediation. These consultations will assist compliance with the NJDEP’sapplicable Site Remediation Program rule requirements and technical guidance.
