[CPEO-BIF] Vapor Intrusion regulatory survey

[Lenny Siegel <lsiegel@cpeo.org>]

The Vapor Intrusion Work Team of the Interstate Technology and
Regulatory Council, of which I am a member, has just published the
results of a nationwide survey of regulatory agency approaches to vapor intrusion.

The survey illustrates that this emerging pathway is being taken
seriously by agencies across the country. It provides valuable
background on the subject, but I have spotted nothing earthshaking in
the results. The survey reviews how the various agencies assess risk,
but it does not report numerical values for any health standards.

I have pasted the survey introductory text below. See the link at the
bottom to view survey results. The site is easy to use.

Vapor Intrusion Survey

In the fall of 2004, the Interstate Technology and Regulatory Council's
(ITRC) Vapor Intrusion Team developed and conducted an on-line survey of
state, federal, and tribal agencies regarding vapor intrusion
regulations, policy, and guidance. The survey results are accessible on
this site. These results can be used by many different groups of people,
including, but not limited to, decision makers, regulators, and
technology developers. These results will also be used by the ITRC Vapor
Intrusion (VI) Team to guide the team's future activities, such as the
development of guidance documents, training, and technology evaluations.

The survey was developed with the intention of collecting regulatory
information and assessing opinions of individual state, tribal, and
federal regulators involved with vapor intrusion sites. To develop the
survey, four subgroups of ITRC VI Team members used standard survey
development methodology to develop and revise questions and responses.
The survey questions were divided into the following five topic areas:
general, media, risk, sampling, and remediation. The responses varied by
question, and included multiple-choice, graded-response,
multiple-selection, and short-answer questions. Once a draft survey was
compiled, a beta-test of the on-line survey was conducted to solicit
feedback on the survey and to estimate the amount of time necessary to
complete the survey.

Once the development process was concluded, ITRC VI Team members and
state points-of-contact (staff members from state environmental
agencies) contacted potential respondents familiar with and involved in
vapor intrusion issues. The survey was available on-line over a six-week
period from August to October of 2004. Ultimately, 54 regulators from 41
states, Canada, and one EPA region responded to the survey.

Summary results of the survey are grouped into the sections listed below
for each general topic area covered in the survey. These results have
been provided as graphs, which are accessible by clicking on each
question link. Please note that because the survey was conducted in the
fall of 2004, the survey data may have changed slightly since that time.
