Based on a continuing review of scientific information, effective July 16, 2013, the Department is requiring the following:<\/p>\n<p>The analysis for 2-methylnaphthalene will not be required for VI samples collected during the investigation of kerosene, jet fuel, diesel fuel, fuel oil No. 2, and heavier petroleum products. The Department intends to update the Technical Requirements for Site Remediation to remove the requirement to analyze VI samples for 2-methylnaphthalene. Until the rule is updated, persons responsible can apply a variance pursuant to N.J.A.C. 7:26E-1.7 to not perform this analysis. The Department has already updated other posted web documents to reflect this change.<\/p>\n<p>Naphthalene analysis will be required for VI samples collected during the investigation of kerosene, jet fuel, diesel fuel, fuel oil No. 2, and heavier petroleum products. In addition to USEPA Method TO-17, the Department will also allow the use of USEPA Method TO-15, NJDEP Method Low Level TO-15 and USEPA Method TO-13 A. Any laboratory performing the methods must have the applicable laboratory certifications and must have a demonstrated reporting limit of less than or equal to 3 ug\/m3 consistent with N.J.A.C. 7:26E-2.1(a)3.<\/p>\n<p><a href=\"vi-archive\/\">Vapor Intrusion Pathway Archive documents<\/a>[\/vc_column_text][\/vc_column][vc_column offset=&#8221;vc_col-lg-3 vc_col-md-3&#8243; el_class=&#8221;order-1 swap-on-mobile&#8221;][vc_column_text]<\/p>\n<div class=\"card bg-light mb-3\">\n<div class=\"card-body\">\n<h5 class=\"card-title\">Additional Vapor Intrusion Information<\/h5>\n<ul class=\"\">\n<li><a href=\"vi-archive\/\">Vapor Intrusion Pathway Archives<\/a><\/li>\n<li><a href=\"vi-contacts\/\">DEP Contacts for Vapor Intrusion<\/a><\/li>\n<li><a href=\"vig\/\">Vapor Intrusion Technical Guidance<\/a><\/li>\n<li><a href=\"templates\/\">Vapor Intrusion Template Letters &amp; Results Tables<\/a><\/li>\n<li><a href=\"https:\/\/deptest.nj.gov\/srp\/wp-content\/uploads\/sites\/39\/community_outreach_guidance.pdf\">Community Outreach Guidance<\/a> <span class=\"text-12\">[pdf]<\/span><\/li>\n<li><a href=\"indoor-air\/\">Fact Sheet: Evaluating Indoor Air Near VOC Contaminated Sites<\/a><\/li>\n<li><a href=\"subsurface\/\">Fact Sheet: Subsurface Depressurization Systems<\/a><\/li>\n<li><a href=\"https:\/\/deptest.nj.gov\/srp\/wp-content\/uploads\/sites\/39\/household_sources_of_contamination.pdf\">Common Household Sources of Background Indoor Air Contamination<\/a> <span class=\"text-12\">[pdf]<\/span><\/li>\n<li><a href=\"https:\/\/www.nj.gov\/health\/ceohs\/documents\/tce_factsheet.pdf\">NJDOH&#8217;s Fact Sheet: Potential Health Risks Associated with Exposures to Trichloroethylene (TCE) in the Indoor Air<\/a> <span class=\"text-12\">[pdf] Posted 1 June 2016<\/span><\/li>\n<\/ul>\n<h5 class=\"card-title\">Related Links<\/h5>\n<ul class=\"\">\n<li><a href=\"..\/\">Guidance Library \u2013 <span class=\"text-14\">[Home]<\/span><\/a><\/li>\n<li><a href=\"https:\/\/deptest.nj.gov\/dsr\/oqa\/\">NJDEP Office of Quality Assurance<\/a><\/li>\n<li><a href=\"newmethod2007\/\">New Analytical Method for Volatile Organics in Air NJDEP-LLTO-15- 3\/2007<\/a><\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column offset=&#8221;vc_col-lg-9 vc_col-md-9&#8243; el_class=&#8221;order-2&#8243;][breadcrumb-shortcode][vc_column_text css=&#8221;&#8221;] Vapor Intrusion Pathway The presence of volatile chemicals in contaminated soil or ground water offers the potential for chemical vapors to migrate through subsurface soils and\/or preferential pathways (such as underground utilities) thereby impacting the indoor air quality of area buildings.
