Welcome, Agenda, and Meeting Objectives
Gretchen Hund welcomed the committee stakeholders to the second AMS Center Air
Stakeholder Committee teleconference of 2006. Ms. Hund stated that this teleconference will be
the first teleconference to use Live Meeting as part of a Stakeholder Committee meeting; she
hopes the stakeholder group likes this format of the teleconference.
ETV Program Update
Amy Dindal, Battelle AMS Center Verification Testing Leader, provided an update on the ETV
Program, including an overview of the 2nd International Environmental Technology Verification
Forum held in Vancouver on March 28 and the availability of the recently published ETV
Program Case Studies document available on the ETV web site. This document includes a case
study on the ambient ammonia verification test. Regarding the AMS Center, Ms. Dindal
summarized recent water, water security, and air verifications that have either been completed or
are in progress. Finally, she discussed the future of the ETV Program and the impact of the
current funding situation on the sustainability of the AMS Center.
Bob Fuerst, EPA Project Officer for the AMS Center, thanked the stakeholders for their
continued support and said to let him or Ms. Dindal know of any potential ideas or sources of
funding.
Will Ollison asked if the mobile mass spectrometer was adaptable to air monitoring. Ms. Dindal
said the vendor participating in the verification was Constellation Technology who had their CT-
1128 Portable GC-MS verified. Battelle will follow up with Constellation Technology to see if
their technology is adaptable to air monitoring.

Stakeholder Introductions and Insights
Ms. Hund asked each stakeholder to provide a brief introduction, describe his or her role within
their organization, and any ideas they may have regarding leads for long-term collaborations for
the AMS Center to pursue.
Don Stedman discussed measuring ammonia emissions from mobile sources. About 25 percent
of NOx emitted from cars is in the form of ammonia, based on data he had seen from Great
Britain.
Rudy Eden suggested looking into the Innovative Clean Air Technologies Program, a California
Air Resources Board (ARE) program that co-funds the demonstration of innovative technologies
that can reduce air pollution. An action item was made to contact Jeff Cook at ARE to learn
more about the program.
Will Ollison would like to see additional instruments provided for criteria air pollutants.
Lindene Patton shared two observations with the group. She is seeing a lot of international ETV
efforts underway related to carbon emissions monitoring and wondered if there were
technologies available to assist with this type of monitoring. She also said there is a need for
improved monitoring for vapor intrusion. States are reviewing the equipment they are using for
vapor intrusion monitoring. Finally, Ms. Patton said she's seeing a need to measure volatile
polychlorinated biphenyls (PCBs). People are using different filter-based techniques in site
evaluations and cleanups.
Ms. Dindal said that regarding vapor intrusion, the AMS Center approached EPA's Office of
Solid Waste and Emergency Response and concluded that there were not enough commercially
available vapor intrusion technologies to warrant testing, but would keep the technology
category on their radar screen for later consideration.
Joann Rice said that EPA is including ammonia monitoring in the new NCORE network and
starting to look at technologies in this area. She also said that technologies that can measure
speciated mercury, continuous nitric acid, and continuous particulate matter (coarse) are of
interest, but not ready for prime time.
Update on Technology Categories
Tom Kelly provided an update on technology categories currently in the verification process.
PowerPoint presentation slides were distributed to all stakeholders before the teleconference, but
were also available as part of the Live Meeting. Four air verifications are either in development
or nearly completed.
Dr. Kelly reviewed the Dioxin Emission Monitoring Systems (EMSs) verification test. He
reviewed the collaborators who provided co-funding including EPA's Office of Solid Waste,
Office of Research and Development, and OAQPS, as well as the Chlorine Chemistry Council.

He then described the four technologies that are undergoing verification and the test design. Dr.
Kelly briefly described some of the draft results.
Dr. Kelly said the y-axis on the graph depicted the total toxicity equivalents (TEQ) of
polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) reported in
terms of nanograms per dry standard cubic meter. The dioxin EMS reports are currently in peer
review. The reports are being reviewed by Tom Logan, Ernie Bouffard, and representatives from
the co-funding organizations.
Dr. Kelly reviewed slides detailing the verification test of a Personal Cascade Impactor
Sampler (PCIS) for collection of ambient particulate matter (PM). One technology is currently
undergoing verification. Dr. Kelly briefly described some of the draft results. The final report is
anticipated in the July 2006 timeframe.
Responding to several stakeholder questions, Dr. Kelly said that so far the PCIS flow testing
simulated an unloaded (i.e., unrestricted) impactor. He also said that under a later task, flow
restrictions will be imposed to determine flow performance under a range of pressure drop
conditions. Dr. Kelly said in terms of cut-sizes, there are up to eight stages below five microns.
Acceptance testing, in which human volunteers will wear the PCIS for 48 hours, will begin
shortly. The final report on the PCIS is expected by July.
Dr. Kelly moved to the third technology category, Hg CEMs Round III. He described the
Indiana facility hosting the upcoming verification test scheduled for the June-July 2006
timeframe, and reported that two vendors are likely to participate. Dr. Kelly said that the
verification test will now be referred to as a test of mercury monitors because one of the
participating technologies is a sorbent sampling technology and not a continuous emission
monitor (CEM). Dr. Kelly also discussed the reference sampling that will be conducted at the
facility. (Post-meeting note: Two additional vendors have committed to participate, Thermo
Electron, a CEM vendor, and ESC, Inc., a sorbent sampler vendor.)
Dr. Stedman brought up an issue regarding mercury calibration and offered to forward original
literature on the controversy about the vapor pressure of mercury.
Dr. Kelly reviewed the final technology category, Remote Leak Detection Devices. He noted
that discussions are still underway within the ETV/AMS Center to perform a data verification of
existing American Petroleum Institute (API) lab data on these technologies. API already funded
laboratory testing of detection of petroleum hydrocarbons with two leak detection infrared
cameras. Dr. Kelly described other recent developments for remote leak detection device testing
with EPA Region 6 and a separate development with the American Chemistry Council (ACC).
ACC is interested in conducting lab testing for chemicals other than petroleum hydrocarbons.
Potential Technology Categories
Dr. Kelly provided an update on the status of three potential technology categories. Applied
Materials is a vendor interested in the AMS Center verifying their technology for characterizing
air emissions using a Fourier Transform Infrared/Mass Spectrometer (FTIR/MS) instrument that
is incorporated into a mobile laboratory. Their main application is Semi-Conductor Industry
Emission Monitoring. Dr. Kelly said the next step would be to approach the semi-conductor

industry or trade associations to secure co-funding to support the test. Dr. Stedman thought
another vendor might exist and noted that a lot of groups seem to be interested in this type of
monitoring. Stakeholders seemed to be in concurrence with this technology category.
Dr. Kelly said that Siemens Power Generation contacted Battelle with interest in Ultrafine
Particulate Monitoring from emission sources, specifically, particulate testing (EPA Method 5
and Method 202, filterable and condensable particulates respectively). He then noted that in
previous meetings Judy Chow recommended ultrafine particulate technologies for ambient air
monitoring. She has drafted a manuscript with some preliminary comparison test data, but
recommending waiting to view the information until after the paper is published.
Mr. Eden said ultrafine particulate monitoring for emissions sources and in ambient air is of
great interest and importance in California's Southwest Basin. Regarding ambient air
monitoring, Mr. Eden said that he knows of some technologies that would be of interest. Joann
Rice noted that there is a growing interest in the health effects community for these technologies.
An action item was made to contact Mr. Eden to discuss ultrafine particulate monitoring further.
Regarding partnering opportunities, Ms. Rice will try to locate a contact at EPA who could
possibly help get our foot in the door with the health effects research community.
Dr. Kelly provided information on MSI Mechanical Systems, a Continuous Particulate
Emission Monitor vendor interested in verification. Dr. Kelly was planning on meeting with the
vendor in early May at the EPRI CEM Users Group meeting in Columbus. Roy Owens
commented that such a monitor could be valuable for monitoring processes, as well as
determining emissions.
Hot Topics
Ms. Hund asked the stakeholders if they were aware of any new opportunities that the ETV/AMS
Center should be exploring. No new opportunities were raised during the call.
Review of Action Items
1. Battelle will follow up with Constellation Technology to see if their portable GC-MS
technology is adaptable to air monitoring.
2. Battelle will contact Jeff Cook at California ARB to learn more about the Innovative
Clean Air Technologies Program.
3. Dr. Stedman said that he will forward original literature on the controversy about the
vapor pressure of mercury.
4. Battelle will follow up with Mr. Eden to discuss ultrafine particulate monitoring further.
Future Meeting Schedule
Ms. Hund said that because of busy travel schedules during the summer months, another
teleconference in September would be ideal. The stakeholders agreed to a teleconference in this
timeframe. It was agreed by several stakeholders that the Live Meeting format was very efficient
and worth continuing.
