Remediation activities under DEP oversight are conducted by responsible parties  (RP) or, absent a responsible party, are publicly funded. RP sites include regulated underground storage tanks, industrial sites governed under the ISRA legislation (ISRA: Industrial Site Recovery Act, formerly known as ECRA, the state Environmental Cleanup Responsibility Act of 1983 requires owner/operators to address environmental contamination that may be on-site prior to the transfer, sale or closure of subject industrial properties) and individual homeowner tank cases, among others. Superfund sites include both publicly funded and RP cases, and are jointly managed by NJDEP and EPA. More information.
