Subject: Petroleum Hydrocarbons And Chlorinated Hydrocarbons Differ In Their Potential For Vapor Intrusion -- Final Version


EPA's Office of Underground Storage Tanks (OUST) is developing  guidance
for investigating potential intrusion of petroleum vapors into inhabited
buildings thereby threatening public health and safety.  As part of that
effort, OUST recently finalized Petroleum Hydrocarbons And Chlorinated
Hydrocarbons Differ In Their Potential For Vapor Intrusion, which is now
available on EPA's website at www.epa.gov/oust/cat/pvi/pvicvi.pdf.  This
document describes how petroleum and chlorinated hydrocarbons behave
differently in the subsurface and how these differences can influence
whether there is a potential for vapor intrusion to occur.  This version
addresses public comments that OUST solicited in July.

OUST is also developing a compendium of information about petroleum
vapor intrusion (PVI) which will be available in the next several weeks
via OUST's home page at www.epa.gov/oust.  If you want more information
about the petroleum hydrocarbons and chlorinated hydrocarbons document,
the PVI compendium, or PVI in general, please contact Hal White of my
staff at white.hal@epa.gov or 703-603-7177.
