For example, “practical quantitation limit” would be replaced by “reporting limit.” “Vapor intrusion screening levels” would become “soil remediation standards for inhalation exposure pathway.” The DEP would also have to update its existing technical guidance and develop new guidance to adapt to the multitude of changes. 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. NJDEP Proposes Major Revisions to Remediation Standards ... 7:26D, primarily those standards for soils and vapor intrusion. CSI Environmental, LLC GUIDANCE MANUAL - WV Department of Environmental … The term “Vapor Intrusion Screening Levels” or “VISLs” is used as a generic term for regulatory standards. 2. 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. 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 Vapor Intrusion. NJDEP Click here to review the New Jersey Department of Environmental Protection Site Remediation Program Vapor Intrusion Technical Guidelines. 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. ; Vapor Intrusion Screening Value Tables (Excel) – These screening tables are updated when the numeric values used to calculate … on the most conservative exposure pathway (i.e. Table 3: Groundwater Screening Levels for Alternate Soil Textures. Again, several compounds have lower screening levels, screening levels for some compounds are less stringent and several were deleted from regulation altogether. An active subsurface depressurization (SSD) system was installed under the sub-slab of the impacted buildings to remediate VI intrusion. Vapor Intrusion Technical Guidance version 5.0 is being issued primarily to reflect the recent incorporation of vapor intrusion screening levels as the … The observations made from these comparisons are presented in Section 4. Table 1: Generic Vapor Intrusion Screening Levels. Emergency situations involving the risk of explosion or acute exposure to high vapo… Alpha Analytical's online data management tool, Data Merger features an option to concurrently review a full TO-15 lis t against the current EPA Vapor Intrusion Screening levels VISL. The NJDEP VI Guidance is used in the implementation of vapor intrusion programs throughout New Jersey. NJDEP Site Remediation Program, Vapor Intrusion Technical Guidance, Jan 2018 Toxicity Class (EPA Regionional Screening Levels (RSL) Table, Nov 2018) Value exceeds the theoretical risk that 1 additional case of cancer will occur in a population of 1 million than statistically expected. 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). New Jersey Department of Environmental Protection (NJDEP) vapor intrusion screening levels are noted in the table and can be found here. 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 … This version included a significant clarification to the discussion of petroleum hydrocarbons (PHC). These tables present the revised statewide health standards that were published November 20, 2021 in the Pennsylvania Bulletin. Pennsylvania Department of Environmental Protection (DEP) vapor intrusion screening levels are noted in the table and can be found here. 2. The remediation of sites or areas of concern that are active cases on or after May 17, 2021, is required to use the 21 ug/m3 (residential) and 88 ug/m3 (nonresidential) indoor air remediation standards for 1,1-dichloroethene. The existing rules do not address remediation standards for indoor air (“IA”) by way of the vapor intrusion (“VI”) exposure pathway, again relying on “screening levels” and “rapid action levels” by reference to guidance documents to trigger certain remedial obligations. 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 The information in the Department’s Vapor Intrusion Technical Guidance (Version 5.0) document is provided free of charge to the public. development of screening levels and building design considerations, are included as appendices. Our goal has always been to provide responsive, competent, cost effective professional services. In March 2013, NJDEP issued revised Vapor Intrusion Technical Guidance and Screening Levels. The tightening of some standards and the loosening of others. 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. The New Jersey Department of Environmental Protection (NJDEP) has published a Vapor Intrusion Technical Guidance (VITG) document, which includes vapor intrusion screening levels (VISL) for evaluating the need to perform vapor intrusion (VI) sampling, monitoring and mitigation. Once the information packages are distributed, EPA, NJDEP and DuPont plan to be available to individuals or groups to discuss the content of the Technical Guidance (NJDEP VI Guidance) including their Vapor Intrusion Screening Levels. Concentrations of TCE, PCE, and chloroform detected in these buildings have exceeded the NJDEP VI screening levels. For example, “practical quantitation limit” would be replaced by “reporting limit.” “Vapor intrusion screening levels” would become “soil remediation standards for inhalation exposure pathway.” The DEP would also have to update its existing technical guidance and develop new guidance to adapt to the multitude of changes. The State of New Jersey, its agencies and employees assume no responsibility to any person or entity for the use of this information. For your convenience, we have compiled these 2007 vs. 2013 comparison tables into a single PDF file. NJAC 7:26D-7.3, basis for the development/request of alternative remediation standard may include: 1. New chemical toxicity data; 2. New risk assessment models or methods; 3. Alternate land use planned for Site; 4. Site specific conditions supporting modification of input parameters for SRSs The only indoor air remediation standard impacted by an order of magnitude or more decrease of an indoor air screening level is that of 1,1-dichloroethene. 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). Vapor Intrusion Guidance Seminar - October 21, 2014 in Mount Laurel, NJ. The current values are those dated March 2013, released along with the prior version of the VI guidance (Version 3.1, March 2013). This is also known as Vapor Intrusion (VI). lower of the direct contact or vapor intrusion screening value). The Florida Department of Environmental Protection is the state’s lead agency for environmental management and stewardship – protecting our air, water and land. Several assessments are included with the guidelines, models, databases, state-based RSL Tables, local contacts and framework documents used to perform these assessments.
