This afternoon, April 16, 2013, USEPA's Office of Solid
Waste and Emergency Response released for public input two draft
vapor intrusion guidance documents: a general guidance for all
compounds; and one focused on petroleum hydrocarbons released from
underground storage tanks. The documents can be accessed at: http://www.epa.gov/oswer/vaporintrusion. Public
input must be submitted by May 24, 2013, at: http://www.regulations.gov; docket number:
EPA-HQ-RCRA-2002-0033-007.
As reported previously on this blog, our office was among those
who formally petitioned USEPA, in December 2012, to release these
documents for public comment on the basis that the leaked versions
revealed an approach that has fundamentally changed from the last
general USEPA draft from 2002. We appreciate that OSWER has taken
this important step, and we encourage all interested stakeholders
to review these important documents and provide their input. Please
reach out to a member of our group if you
