On November 4, 2009, the New Jersey Department of Environmental Protection (“DEP”) issued regulations for the new site remediation requirements under the Site Remediation Reform Act. One of the most significant requirements of the new law is that all new cleanup cases are required to be competed through the use of a Licensed Site Remediation Professional (“LSRP”). The LSRP essentially acts in the place of the DEP to ensure that a cleanup meets all applicable remediation requirements. Once the LSRP is satisfied that the cleanup is completed, the LSRP will issue a Response Action Outcome (“RAO”) letter for the cleanup. The RAO is the equivalent of a DEP-issued No Further Action letter – it is the document which formally closes a cleanup case.
