N.J. Stat. § 58:10C-16.1
If a licensed site remediation professional obtains specific knowledge of a condition in an unoccupied structure, that, in the licensed site remediation professional's independent professional judgment, constitutes an immediate environmental concern, and the person responsible for conducting the remediation provides to the department a written certification from the property owner that the building (i) is not occupied, (ii) will not be occupied, and (iii) will be demolished, then no further remediation relative to the immediate environmental concern in the unoccupied structure shall be required, provided the conditions of the certification are maintained. Nothing in this section shall be construed to limit the responsibility of a licensed site remediation professional to comply with the notification requirements of subsection j. of section 16 of P.L. 2009, c. 60(C.58:10C-16), or the responsibility of a person to report a discharge pursuant to P.L. 1976, c.141 (C.58:10-23.11 et seq.). The department shall prescribe the form and manner of the written certification pursuant to this section.
