EnviroGroup Limited
AEHS West Coast Conference

The Association for Environmental Health and Sciences is holding its 18th Annual AEHS Meeting and West Coast Conference in San Diego, CA on March 10-13, 2008. A full day of vapor intrusion presentations is scheduled for Wednesday, March 12. Jeff Kurtz of EnviroGroup will be presenting a paper on observed time lags between groundwater concentration changes and vapor intrusion impacts. Registration information can be found at:

EPA National Stakeholders Forum on Vapor Intrusion

In conjunction with the AEHS West Coast Conference EPA will be holding a three hour pilot stakeholder's forum on vapor intrusion on March 12. Stakeholders include people whose homes, businesses, or schools have been investigated or identified as being candidates for vapor intrusion mitigation. At the forum EPA will be seeking suggestions for improving its approach to addressing vapor intrusion issues. An all day specialty seminar on the USEPA/ITRC Vapor Intrusion Guidance Update is also scheduled on Thursday, March 13. Drafts of two technical papers will be discussed at this seminar: EPA's National Vapor Intrusion (Attenuation) Database and "Background" Levels of Contaminant Vapors in Non-Impacted Buildings. Information on the forum and workshop is available at:

Colorado Petroleum Hydrocarbon VI Guidance Document

On December 11, 2007 the Division of Oil and Public Safety of the Colorado Department of Labor and Employment issued its Petroleum Hydrocarbon Vapor Intrusion Guidance Document. This document describes how to assess the vapor intrusion pathway and is intended to be used in conjunction with the Petroleum Storage Tank Owner/Operator Guidance Document. The document is available at:

AFCEE Technology Transfer Workshop

The Air Force Center for Engineering and the Environment will be hosting a technology transfer workshop on March 25-28 in San Antonio, TX. The workshop is open to DOD managers, academia, and state and federal regulators. Industry attendance is limited to current AFCEE contractors, two individuals per firm. On Thursday March 28 there is an all day session on vapor intrusion, including a presentation by Dave Folkes of EnviroGroup on mitigation strategies for buildings, bases, and other large complexes. Information on the workshop can be obtained at:

Battelle Conference on Remediation of Chlorinated and Recalcitrant Compounds

Battelle will be hosting the Sixth International Conference on Remediation of Chlorinated and Recalcitrant Compounds on May 19-22, 2008 in Monterey, CA, including a session on vapor intrusion mitigation. ITRC will be giving a half day short course on vapor intrusion investigation and mitigation on Sunday May 18 - Dave Folkes of EnviroGroup will be one of the instructors at this course. Information on the conference is available at:

American Industrial Hygiene Conference and Expo

The American Industrial Hygiene Conference and Expo will be held May 31-June 5 in Minneapolis, MN. On Thursday, June 5, there will be a half day workshop on Recent Developments in Vapor Intrusion. Dave Folkes of EnviroGroup, one of the invited speakers, will speak on the new (expected to be published late February 2008) ASTM standard on the evaluation of vapor intrusion during real estate transactions. A listing of the presentations at the workshop is located at:

Annual National Tanks Conference and Expo

The 20th Annual National Tanks Conference and Expo will be held March 17-19, 2008 in Atlanta, GA. On Sunday, March 16, a half day workshop on assessing Vapor Intrusion at Petroleum Release Sites will be held. Information on the workshop can be obtained from:

California Brownfields Bill

A bill, AB 422, has been introduced into the California Senate which would require that brownfields cleanups involving volatile organic compound releases include an assessment of the vapor intrusion pathway. The bill would amend the Carpenter-Presley-Tanner Hazardous Substance Account Act (California Superfund Act). More information can be found at:

New ASTM Vapor Intrusion Standard (E2600)

ASTM expects to publish its new "Standard Practice for Assessment of Vapor Intrusion into Structures on Property Involved in Real Estate Transactions" later this month. The standard will complement (and not replace) the existing standard for conducting Phase 1 environmental site assessments (ASTM E-1527). The new vapor intrusion standard will provide a tiered approach to evaluating and, if necessary, mitigating vapor intrusion impacts, with a focus on screening out properties without significant risk of vapor intrusion early in the process, in many cases based on the same information collected during a Phase 1. Dave Folkes of EnviroGroup co-chaired one of the work groups that helped develop the standard. We will issue a special edition of this newsletter when the ASTM vapor intrusion standard becomes available.
