Does New Jersey allow the use of Risk Based Corrective Action?
Yes, New Jersey uses Risk Based Corrective Action in all underground storage tank cases. There are two possible paths or Tiers which are: NJ RBCA Tier I: Compare initial Site Investigation or Remedial Investigation work to New Jersey’s Soil Cleanup Criteria (latest version 7/11/96) and the Ground Water Quality Standards. Remediate to these levels or move to Tier II. NJ RBCA Tier II: Define the extent of soil and ground water contamination to unrestricted use levels. Conduct appropriate contaminant fate and transport modeling to determine what levels of contamination can be left behind to prevent direct contact under engineering and institutional controls, to prevent further degradation of ground water, and to allow ground water to naturally attenuate under a Classification Exception Area. Conduct a risk assessment consistent with the EPA’s methodology for an alternate direct contact soil cleanup standard.
