ITRC PVI Project Snapshot: In October 2014, the ITRC Petroleum Vapor Intrusion (PVI) Team will publish a web-based technical and regulatory guidance that describes a multiple lines of evidence approach for evaluating PVI. The guidance document describes the differences between chlorinated and petroleum vapors in the vadose zone and provides a comprehensive practical methodology for screening, investigating, and mitigating sites for PVI. The ITRC PVI guidance document includes investigative approaches for a variety of petroleum site types including:

  • Gasoline and/or Diesel USTs
  • Commercial/Home Heating Oil Tanks
  • Refineries
  • Bulk Storage Facilities
  • Pipelines and Transportation
  • Oil Exploration and Production (E&P)
  • Former Manufactured Gas Plants
  • Creosote (Wood Treating) Facilities
  • Dry Cleaners Using Petroleum Solvents

Targeted Users: Target users are engaged in vapor intrusion issues at petroleum hydrocarbon contaminated sites (i.e., gas stations, refineries and storage terminals, heating oil facilities, military installations).

Primary Users

  • State / Federal Regulators – Project Management level
  • Consultants – Field work level

Secondary Users

  • Site owners
  • Public and tribal stakeholders
  • Regulatory and consultant management
