[SRRA] NJDEPs Site Remediation Program Announces the Availability of New Technical Guidance: Off-Site Source Ground Water Investigation

Document Description:
This Technical Guidance provides tools and strategies to aid the investigator in developing lines of evidence to support the determination that one or more contaminants are migrating onto a site from an off-site property. It describes the regulatory requirements outlined in N.J.A.C. 7:26E-3.9 for investigating and documenting the presence of an off-site source of contamination, and presents the administrative approach for notifying the Department and issuing a Remedial Action Outcome (RAO) to address the contamination.

This Technical Guidance was developed with stakeholder input by the NJDEP Off-site Source Investigation Technical Guidance Committee. The Department would like to thank Committee Chairs George Nicholas and Christina Page, and all Committee Members for their time and effort in developing this Guidance document. The Technical Guidance and associated Response to Comments document are available for viewing and downloading on the SRP's Guidance Library webpage at www.nj.gov/dep/srp/guidance.

Technical guidance may be used immediately upon issuance. However, the Department recognizes the challenge of using newly issued technical guidance when a remediation affected by the guidance may have already been conducted or is currently in progress. To provide for the reasonable implementation of new technical guidance, the Department will allow a 6-month “phase-in” period between the date the technical guidance is issued final (or revised) and the time it should be used.
