USEPA Provides Final Guidance for Addressing Vapor Intrusion Pathway

Two new documents released in June present current technical recommendations from the EPA regarding vapor intrusion into indoor air from subsurface vapor sources.  The Agency's intent is to promote national consistency in assessing the vapor intrusion pathway.  For various state agency clean-up programs, vapor intrusion will need to be addressed.  These guidance documents will support proposed sampling plans required for subsurface investigations.  The complete documents can be found here.   

 

USEPA, OSWER TECHNICAL GUIDE FOR ASSESSING AND MITIGATING THE VAPOR INTRUSION PATHWAY FROM SUBSURFACE VAPOR SOURCES TO INDOOR AIR
  • This document is intended to be used at any site being evaluated by EPA pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended, or the corrective action provisions of the Resource Conservation and Recovery Act (RCRA), as amended. It is also intended to be used by EPA's brownfield grantees, or state agencies acting pursuant to CERCLA or an authorized RCRA corrective action program where vapor intrusion may be a concern. It applies to both residential and non-residential settings.

 

USEPA, TECHNICAL GUIDE FOR ADDRESSING PETROLEUM VAPOR INTRUSION AT LEAKING UNDERGROUND STORAGE TANK SITES

  • This document is intended to be used at any site impacted by petroleum contamination from underground storage tanks where vapor intrusion may be a potential concern. It applies to both residential and non-residential settings.

USEPA Issues Significant Rule Revisions for Underground Storage Tanks

The USEPA issued significant revisions to the 1988 federal underground storage tank rules and related 1988 State Program Approval (SPA) regulations on June 19, 2015.  The new rules provide stricter requirements regarding preventing and detecting petroleum releases from USTs (to protect groundwater), and are also intended to help ensure that all USTs in the United States - including those in "Indian country" (as defined in 18 U.S.C. � 1151) - meet the same minimum standards. This is the first major revision to the federal UST regulations since 1988 and will affect virtually all owners and operators of regulated USTs.

 

Illinois is one of the 16-non-SPA states and territories that must meet the federal requirements according to the schedule in the 2015 UST regulation. In addition, owners and operators will need to follow their state requirements.
