On August 5, 2021, the New Jersey Department of Environmental Protection (“NJDEP”) issued updated guidance on requirements for evaluating Contaminants of Emerging Concern (“CECs”), such as per- and polyfluoroalkyl substances (PFAS).
The August 5th NJDEP update specifically addresses 4 CECs, including: PFAS; 1,4-dioxane; 1,2,3-trichloropropane (1,2,3-TCP), and perchlorate.
The requirement to evaluate CECs applies to any site currently undergoing remediation in NJ, as well as sites that have already completed the active remedial process but have ongoing maintenance or monitoring obligations. As an example, for a site where a Remedial Action Permit has already been obtained, but a Classification Exception Area (CEA) is in place, the Licensed Site Remediation Professional (LSRP) for the site will need to conduct a CEC evaluation for the site. Likewise, for sites that are still in the remediation process, the LSRP is required to assess whether one or more of the 4 specified CECs is a potential contaminant of concern at the site.
While this may have slipped under the radar for some, parties with ongoing compliance obligations at a remediated site should understand that a CEC evaluation will be required as part of their next report submission. For instance, NJDEP has updated its Biennial Certification forms to specifically require a CEC evaluation as part of the submittal for sites with Remedial Action Permits.
