EPA Vapor Intrusion Guidance
Comments
On November 29, 2002 EPA published a
notice in the Federal Register seeking comment on
the draft guidance "Evaluating the Vapor Intrusion
to Indoor Air Pathway from Groundwater and Soils".
Comments were due February 27, 2003. Twenty seven
comments were received electronically on the
document and they are available on the EPA
EDOCKET. Additional hard copy comments were
received and have not yet been added to the
docket. The comments can be reached through the
EPA web site (click below). This sites takes a few
minutes to load. Scroll down to the bottom of the
page to see the entry for each comment received.
Click on the Rendition icon on the for right to
see the full text of each comment.
Comments
were received from ten state agencies and a number
of industrial groups including the American
Petroleum Institute, American Chemistry Council,
the RCRA Corrective Action Project, and the
Utility Solid Waste Activities Group.
EPA Request for Vapor Intrusion Site
Data
EPA has created a data base to collect,
store, and share site data to advance the state of
knowledge regarding vapor intrusion. These data
will be used by EPA to determine if the screening
level predictions contained in the draft vapor
intrusion guidance are appropriately protective of
public health. Many of the industry comments
received on the guidance express concern that the
screening numbers are overly conservative. Ideally
EPA would like high quality ground water, soil
gas, and indoor air site data. The data can be
preliminary at this time and updated later. The
web site for the Vapor Intrusion Database,
maintained by an EPA contractor, may be reached by
clicking on the link below. If you are interested
in contributing data the project manager, Jennifer
Lloyd, can be contacted at: jml@rti.org.
New Jersey Releases Guidance
Document
The New Jersey Department of Environmental
Protection Site Remediation Program released in
April 2003 the document: "Indoor Air VOC Sampling
and Analysis Requirements". It is available at the
link below. Also available on that web site is the
New Jersey Indoor Air Building Survey and Sampling
Form and Instructions for Occupants - Indoor Air
Sampling Events.
Wisconsin Releases Guidance
Document
The Wisconsin Department of Health and
Family Services, Division of Public Health,
released, on February 13, 2003, Guidance for
Environmental Consultants and Contractors titled
"Chemical Vapor Intrusion and Residential Indoor
Air" It provides general orientation material in
order to better understand this subject. It can be
found at:
Pennsylvania Draft Guidance
The Pennsylvania Department
of Environmental Protection, Bureau of Land
Recycling and Waste Management, has prepared a
draft guidance document on "Vapor Intrusion Into
Buildings from Groundwater and Soil under the Act
2 Statewide Health Standard". When finalized it
will be incorporated into the Land Recycling
Program Technical Guidance Manual. This detailed
guidance includes tables of screening numbers for
both ground water and soil. The draft document may
be found at:
Alaska Tech Memo on Diesel
Vapors
The Alaska Department of Environmental
Conservation, Contaminated Sites Remediation
Program has issued a technical memorandum
summarizing the approaches that various states
take to diesel vapor in indoor air. It discusses
approaches used by seven states and includes some
useful references. The memorandum is available
at:
RCRA National Meeting
This years RCRA National
Meeting is titled "Putting Resource Conservation
into RCRA" and is cosponsored by EPA and a number
of professional organizations. It is scheduled for
August 12-15 in Washington, DC. There will be
several vapor intrusion related sessions included
in this meeting. Registration information is on
the Air and Waste Management Association web site
