VI testing/sampling is required if contaminants present in a Site’s groundwater exceed the standards of the New Jersey Department of Environmental Protection’s (NJDEP) VI Groundwater Screening Levels (VISL). with the requirements of the New Jersey Department of Environmental Protection (NJDEP or Department) and properly assess the VI pathway. The Vapor Intrusion (VI) Guidance was revised to address scientific advancements made since it was first published in 2004. Vapor intrusion should be considered when there is a known source of soil or groundwater contamination nearby and conditions like soil type and depth to groundwater indicate a potential for vapor intrusion exists. <a href="https://www.epa.gov/sites/production/files/2016-10/documents/plksvi_communication_package_13may2015.pdf">GUIDANCE SHEET - US EPA</a> <a href="https://www.csgenvirolaw.com/2021/06/njdep-shifts-approach-to-remediation-in-revised-remediation-standards/">NJDEP</a> <a href="https://www.state.nj.us/dep/srp/guidance/srra/draft_vapor_concern_interim_tech_guide.pdf">New Jersey Department of Environmental Protection Site ...</a> <a href="https://www.maine.gov/dep/spills/publications/guidance/rags/VI-Persistent-Chems-Guidance-final-020516.pdf">Supplemental Guidance for Vapor Intrusion</a> NJ DEP Vapor Intrusion Soil Gas Screening Levels OH EPA Indoor Air Standards due to Vapor Intrusion (Commercial Land Use Category) OH EPA Indoor Air Standards due to Vapor Intrusion (Residential Land Use Category) NIOSH and OSHA Exposure Limit Comparisons PA DEP - Table 5. 1.

Vapor Intrusion Technical Guidance version 5.0 is being issued primarily to reflect the recent incorporation of vapor intrusion screening levels as the … Indoor Air Vapor Intrusion Screening Levels. Guidance Documents Vapor Intrusion New Method March 2007 Updates Log : Low Level Air Analysis Method Required by the NJDEP’s Site Remediation Program Updates Log. Unless the vapor intrusion pathway is determined to be incomplete during the preliminary screening steps, six steps follow that describe the vapor intrusion investigative process (see … **The concentrations of each isomer should be added if multiple isomers are present and compared to the total screening level. New Jersey Department of Environmental Protection Site Remediation Program INTERIM VAPOR CONCERN TECHNICAL GUIDANCE When the results from an indoor air sample exceed the applicable NJDEP Indoor Air Screening Level (but is at or less than the Rapid Action Levels) AND the indoor contaminant is resulting from the vapor intrusion pathway, NJDEP has developed groundwater screening levels (GWSLs), soil gas screening levels (SGSLs), and indoor air screening levels (IASLs) to be used in the third stage. Based upon the concentrations of benzene and cumene detected at locations VI-7 and VI-8, Hercules is aware that additional groundwater delineation will need to be In order to improve enforceability, the NJDEP has proposed to codify the existing indoor air screening levels list as indoor air remediation standards, subject to a few revisions. It presents instructions and the order in which data is reported. However, after much discussion amongst stakeholders, on January 13, 2012, NJDEP finalized its Vapor Intrusion Technical Guidance Document. Tier 2 levels consider depth Several assessments are included with the guidelines, models, databases, state-based RSL Tables, local contacts and framework documents used to perform these assessments. If the Soil Gas Screening Levels are exceeded, indoor air samples shall be collected. These tables present the revised statewide health standards that were published November 20, 2021 in the Pennsylvania Bulletin. 2. However, based on a comparison of the data from subslab soil gas, indoor air, and outdoor air, it is reasonable to conclude that detections of acrolein in indoor air are not related to the potential vapor intrusion pathway. A good check on this issue for a specific sample group is the On the basis of these results, and in accordance with ' RALs "represent trigger levels for the Initiation of prompt action at occupied buildings to further investigate the vapor intrusion pathway and/or minimize impacts to building occupants through the implementation of an interim remedial measure" (NJDEP, 2007). 7:26D, primarily those standards for soils and vapor intrusion. 68. on the most conservative exposure pathway (i.e. The concern with vapor intrusion typically involves the potential for chronic health risks due to long-term exposure to relatively low vapor concentrations, although extreme cases can occur (e.g., explosion risks due to methane gas). 1. The term “Vapor Intrusion Screening Levels” or “VISLs” is used as a generic term for regulatory standards. The adoption of new standards for soil leachate (for the migration to groundwater exposure pathway) and indoor air (for the vapor intrusion exposure pathway); the vapor intrusion standards replace the former screening levels based on NJDEP guidance. Click here to review the New Jersey Department of Environmental Protection Site Remediation Program Vapor Intrusion Technical Guidelines. Vapor intrusion should be considered when there is a known source of soil or groundwater contamination nearby and conditions like soil type and depth to groundwater indicate a potential for vapor intrusion exists. On January 16, 2013, NJDEP released an update to its Vapor Intrusion Technical Guidance and updated its Vapor Intrusion Screening Levels. JM Sorge, Inc. assumes no responsibility for errors. Again, several compounds have lower screening levels, screening levels for some compounds are less stringent and several were deleted from regulation altogether. Indoor air screening levels are currently set forth in the NJDEP’s vapor intrusion guidance. The VIG was updated to include revised vapor intrusion screening levels for groundwater and soil gas in addition to the promulgation of enforceable indoor air standards. Vapor intrusion is a potential human exposure pathway -- a way that people may come into contact with hazardous vapors while performing their day-to-day indoor activities. New Jersey Department of Environmental Protection (NJDEP) vapor intrusion screening levels are noted in the table and can be found here. Vapor Intrusion Guidance Seminar - October 21, 2014 in Mount Laurel, NJ. Due to routine updates to the screening level tables, it is recommended that the user refer to the NJDEP Vapor Intrusion web site at https://www.nj.gov/dep/srp/guidance/vaporintrusion/ for the latest information. A notice will be placed on the web site to indicate future changes to this guidance. Note: This file does NOT include the tables. Indoor air vapor intrusion screening levels to become remediation standards. The vapor intrusion Screening Method has been drafted to assist NDEP case officers in the decision-making process for site cleanups under Nevada Administrative Code (NAC) 445A.226 to 445A.22755. vapor intrusion pathway by comparing the existing data against the screening levels developed by NJDEP(lower con-centrations than rapid action levels). sample results were compared to EPA risk-based screening levels (see Table 2a) and NJDEP screening levels (see Table 2b).

Click here to review the New Jersey Department of Environmental Protection Site Remediation Program Vapor Intrusion Technical Guidelines. How the EPA conducts risk assessment to protect human health and the environment. The NJDEP (not the stakeholder group) is reevaluating the current vapor intrusion screening levels and changes to the levels are expected. NJDEP Site Remediation Program, Vapor Intrusion Technical Guidance, Jan 2018 The > column is used to flag exceedances as marked J= Concentration estimated between Reporting Limit and MDL. Following the current NJDEP Vapor Intrusion Guidance recommendations – Exceedance of the Ground Water Screening Levels triggers only the collection of sub-slab soil gas samples. A VI Vapor Concern exists at a structure if: 1) The results of an indoor air sample exceeds the appropriate NJDEP Indoor Air Screening Levels and is at or below the Rapid Action Level; and, 2) The indoor air exceedance is resulting from a completed vapor intrusion pathway (evaluate potential background sources). the NJDEP Vapor Intrusion Screening Levels, other aspects of the vapor intrusion program, or the other components of the environmental cleanup. Emergency situations involving the risk of explosion or acute exposure to high vapo… Naphthalene analysis will be required for VI samples collected during the investigation of kerosene, jet fuel, diesel fuel, fuel oil No. The technical guidance takes the investigator through the various steps of receptor evaluation, petroleum VI screening, VI investigation, mitigation, monitoring and ultimately termination. The West Virginia Department of Environmental Protection (DEP) Vapor Intrusion Screening Levels (VISLs) are noted in the table and can be found here. 1. NJDEP Issues New Vapor Intrusion Standards. Land Recycling Program TGM Section IV: Vapor Intrusion (PDF) – The revised VI Guidance has been included as section IV of the revised TGM which was published and effective on January 19, 2019 (261-0300-101, eLibrary). There are no changes in vapor intrusion screening levels. 8/7/2015 Region 2 serving the people of New Jersey, New York, Puerto Rico and the U.S. Virgin Islands 16. For the soil gas screening levels (i.e., screening levels that identify contaminants related to subsurface conditions), these changes have resulted in more stringent standards for/new regulation of six contaminants, more lenient screening levels for up to 12 contaminants, and deletion of 14 contaminants. Table 2: NJDEP Rapid Action Levels for Indoor Air. Indoor air screening levels are currently set forth in the NJDEP’s vapor intrusion guidance. Indoor air vapor intrusion screening levels to become remediation standards.
