Current through Register Vol. 56, No. 24, December 18, 2024

Section 7:26E-5.3 - Remedial action requirements for residences, schools, and child care centers

(a) For any remediation initiated on or after May 7, 2010, when new construction of, or a change in use to, a residence, a school, or child care center will occur, the person responsible for conducting remediation shall implement at that area of concern:

1. An unrestricted use remedial action;

2. A presumptive remedy consistent with (b) below, and Table 5-1 below; or

3. An alternative remedy.

(b) For any remediation initiated on or after May 7, 2010, when new construction of, or a change in use to, a residence, a school, or a child care center will occur, the person responsible for conducting the remediation shall, except as provided in (c) below, implement an unrestricted use remedial action or a presumptive remedy in the following two situations:

1. A discrete area discharge; and

2. Widespread polychlorinated biphenyl contamination where the planned use is Residential Type I.

(c) For any remediation initiated on or after May 7, 2010, when new construction of, or a change in use to, a residence, a school, or a child care center will occur, when the person responsible for conducting the remediation determines not to use an unrestricted use remedial action or a presumptive remedy, the person responsible for conducting the remediation shall:

1. Propose an alternative remedy by preparing and submitting to the Department for written approval a remedial action workplan pursuant to N.J.A.C. 7:26E-5.5that includes the following information:

i. An analysis describing how:

(1) The presumptive remedy is impractical due to site conditions; or

(2) The alternative remedy would be equally protective over time as the presumptive remedy;

ii. A detailed description of the alternative remedy including specifications for engineering and institutional controls and a plan for monitoring of such controls; and

iii. An explanation of how the alternative remedy is protective of public health, safety and the environment; and

2. Obtain the Department's written approval prior to implementation of the alternative remedy.

(d) For any remediation initiated on or after May 7, 2010, when new construction of, or a change in use to, a residence, a school, or a child care center will occur, the person responsible for conducting the remediation shall submit a remedial action workplan pursuant to N.J.A.C. 7:26E-5.5 and obtain the Department's written approval before implementing a remedial action at any area of concern:

1. Containing unexploded ordnance, polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, hexavalent chromium, or landfills; or

2. When treatment or removal of free product or residual product is not practicable.

(e) The new construction of, or change in use to, a single family residence, school, or child care center is prohibited on a landfill that undergoes remediation initiated on or after May 7, 2010, if engineering controlsare required for the management of landfill gas or leachate.
