[SRRA]: NJDEP Site Remediation & Waste Management Program Announces the Availability of Revised Technical Guidance: Vapor Intrusion Technical Guidance

The Department announces the availability of revised Vapor Intrusion Technical Guidance:

The Vapor Intrusion Technical (VIT) Guidance has been revised from Version 3.1 (March 2013) to Version 4.0 (August 2016). Revisions to the document include a more streamlined presentation that focuses on the most relevant VI issues. Portions of the main text and several appendices have been moved to the NJDEP VI website at www.nj.gov/dep/srp/guidance/vaporintrusion/. New sections have been added on Access, Field Analysis, and Proactive Mitigation. Two new checklists were added to assist Investigators during the design of a mitigation system and monitoring/maintenance inspections. The most significant change in the VIT Guidance involves a new science-based approach to handling VI investigations at petroleum contaminated sites. This new paradigm shift in screening petroleum vapor intrusion (PVI) sites using vertical screening distance is based on the USEPA PVI empirical database and the Interstate Technology and Regulatory Council (ITRC) PVI Guidance.

Technical Guidance Documents can be accessed on the Site Remediation webpage in the Guidance Library (www.nj.gov/dep/srp/guidance/).

Note: Technical guidance may be used immediately upon issuance. However, the Department recognizes the challenge of using newly issued or revised 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 or revised technical guidance, the Department will allow a 6-month "phase-in" period between the date the technical guidance is issued and the time it should be used.
