(d) An updated remediation standard shall be effective on the date the notice of administrative change is filed with the Office of Administrative Law.

(e) An updated remediation standard shall be applied to all sites except, in lieu of the updated remediation standard established pursuant to this subchapter, the person responsible for conducting the remediation may continue to use a remediation standard that is specified in a remedial action workplan or remedial action report for a site, provided that:

1. The remedial action workplan or remedial action report is submitted no later than six months after the effective date of the updated standard;

2. The remedial action workplan or remedial action report is approved by the

Department or is certified by a licensed site remediation professional;

3. The remediation standard specified in the remedial action workplan or remedial action report for a given contaminant is not greater by an order of magnitude than the updated remediation standard; and

4. The remedial action shall comply with the applicable regulatory timeframes pursuant to the Technical Requirements for Site Remediation at N.J.A.C. 7:26E‐5.

SUBCHAPTER 8. ALTERNATIVE REMEDIATION STANDARDS

7:26D‐8.1 Purpose

(a) This subchapter sets forth the procedures for the development and approval of alternative remediation standards for:

1. Soil for the ingestion‐dermal exposure pathway and inhalation exposure pathway;

2. Soil and soil leachate for the migration to ground water exposure pathway; and

3. Indoor air for the vapor intrusion exposure pathway.

7:26D‐8.2 Applicability

An alternative remediation standard developed pursuant to this subchapter in lieu of a remediation standard established by N.J.A.C. 7:26D‐2, 3, 4, 5, or 6, shall be used only at the site or area of concern for which it is developed and approved.

7:26D‐8.3 Development of an alternative remediation standard

(a) An alternative remediation standard for a site or area of concern:

1. May be developed for soil, for the following exposure pathways:

i. Ingestion‐dermal exposure pathway using the procedures at N.J.A.C. 7:26D

Appendix 6, incorporated herein by reference;

ii. Inhalation exposure pathway using the procedures at N.J.A.C. 7:26D Appendix 7, incorporated herein by reference; and

iii. Migration to ground water exposure pathway using the procedures at N.J.A.C.

7:26D Appendix 8, incorporated herein by reference;

2. May be developed for indoor air, for the vapor intrusion exposure pathway, using the procedures at N.J.A.C. 7:26D Appendix 9, incorporated herein by reference.

(b) The Department may, upon its own initiative and in accordance with N.J.S.A. 58:10B‐

12.f(2), require the development and use of an alternative remediation standard for a particular contaminant for a particular site or area of concern that is either more or less stringent than the remediation standards established by this chapter.

(c) The person responsible for conducting the remediation who develops an alternative remediation standard that requires prior approval from the Department shall follow the approval process outlined at N.J.A.C. 7:26D‐8.4.

(d) The person responsible for conducting the remediation who develops an alternative remediation standard that does not require prior approval from the Department shall follow the process outlined at N.J.A.C. 7:26D‐8.5.

(e) In accordance with the Site Remediation Reform Act, at N.J.S.A. 58:10C‐21, the alternative remediation standards developed pursuant to this subchapter shall be subject to the Department inspection and review process as described in the Site Remediation Reform

Act at N.J.S.A. 58:10C‐21a.

7:26D‐8.4 Approval process for alternative remediation standards requiring prior approval from the Department

(a) Except as provided at N.J.A.C. 7:26D‐8.5, the person responsible for conducting the remediation shall obtain prior approval from the Department, in accordance with (b) and (c) below, for an alternative remediation standard developed pursuant to this subchapter before using the alternative remediation standard at a specific site or area of concern.

(b) For each proposed alternative remediation standard, the person responsible for conducting the remediation shall collect and submit to the Department, along with the appropriate form(s) found on the Department’s website at www.nj.gov/dep/srp/srra/forms, the information indicated for the proposed alternative remediation standard as described at

N.J.A.C. 7:26D Appendices 6 through 9, incorporated herein by reference.

(c) The Department shall review the information the person responsible for conducting the remediation submits in accordance with (b) above, and shall respond as follows:

1. If the Department determines that the submitted information is acceptable, then the

Department shall provide the person responsible for conducting the remediation with a written approval for the use of the alternative soil remediation standard at the specific site or area of concern; or

2. If the Department determines that the submitted information is deficient, then the

Department shall provide comments to the person responsible for conducting the remediation describing the deficiencies, in which case:

i. The person responsible for conducting the remediation may correct the deficiencies and may resubmit the information to the Department for its review pursuant to (c) above; or

ii. The person responsible for conducting the remediation may withdraw the request for approval of a proposed alternative remediation standard.

(d) The person responsible for conducting the remediation shall not use the proposed alternative remediation standard if that person does not correct a deficiency noted by the

Department pursuant to N.J.A.C. 7:26D‐8.4(c)2.

7:26D‐8.5 Process for the development of alternative remediation standards not requiring prior approval by the Department

(a) When the person responsible for conducting the remediation is not required to obtain prior approval from the Department for the implementation of an alternative remediation standard developed pursuant to this subchapter, the person responsible shall:

1. For each proposed alternative remediation standard, collect the information indicated for each applicable exposure pathway as described at N.J.A.C. 7:26D Appendices 6, 7, 8, and 9, incorporated herein by reference; and

2. Submit to the Department the information described in (a)1 above with the applicable remedial phase report or workplan pursuant to the Technical Requirements for Site

Remediation, N.J.A.C. 7:26E.
