22. a. Within one year of the effective date of P.L.1993, c.139, the Department of Environmental Protection and Energy shall conduct an audit of the negative declarations and remedial action workplans that have been submitted to the department pursuant to P.L.1983, c.330 (C. 13:1K-6 et al.). On the basis of this audit, and any other information it may have available to it, the department shall adopt regulations identifying, within the Standard Industrial Classification major group numbers listed in the definition of “industrial establishment,” all industries designated by Standard Industrial Classification number subgroups, or classes of operations within those subgroups, that should not pose a risk to public health and safety or to the environment. The audit shall, to the extent practicable, distinguish between hazardous substances or hazardous wastes at an industrial establishment caused by a particular type of industry and hazardous substances or hazardous wastes that exist as a result of activities at an industrial establishment unrelated to the activities of that industry.

b. An industrial establishment for which a remedial action workplan was previously implemented and a no further action letter was received pursuant to P.L.1983, c.330, a negative declaration was previously approved by the department pursuant to P.L.1983, c.330, or for which the department has previously approved a remediation equivalent to that performed pursuant to the provisions of P.L.1983, c.330, and that is designated by a Standard Industrial Classification subgroup or class of operations that does not pose a risk to public health and safety or to the environment as identified in subsection a. of this section, shall not be considered an industrial establishment for the purposes of P.L.1983, c.330.
