REGION 9 NEWSLETTER
Summer 2006, Edition 36
The World Cup is over (Forza Italia!), we're at the end of this year's Tour de France (oh,
what a great Tour it was), and oh yeah the All Star game of baseball just happened
(yea, American League!). That means summer is here again, so Welcome to the
Summer 2006 edition of the Region 9 HSTL Newsletter! While other interests keep us
going outside our workaday world, there are still plenty of interesting things happening in
our world of hazardous waste cleanup. I've collected another batch of new documents,
upcoming workshops, stories of local and national interest, and plenty more. Read on for
more details!
This quarter, I've included information on a technology for GAC regeneration, summaries
of a few recent conferences (NARPM, a Nanotechnology Symposium and the recent
Battelle Conference), background on an opportunity for technical support from the US
Army Corps of Engineers, and the usual offerings on upcoming conferences and new
documents.
If you're an EPA'er, please take advantage of the local technical support available to you,
both in your Regional office and from the ORD labs. ORD has technical support
available for site characterization and monitoring, groundwater issues, engineering and

Landfill Gas Emission Data: Help for Municipalities
(From EPAs NRMRL News - June 7, 2006)
From an air quality perspective, a municipality might be defined as a body of land
surrounded by pollution emissions. These may arise from single sources such as
smokestacks or from "wide-area" sources such as solid waste landfills. Single-source
emissions are relatively well-characterized and thus, easier to control. But solid waste
-------
landfills are a special challenge because of the multiple pathways through which gas can
migrate from landfills and the complex gas mixtures created by decomposing wastes.
EPA ranks landfills as the leading source of methane gas in the U.S.; other landfill gases
include carbon dioxide, hydrogen sulfide, traces of volatile organic compounds (solvents,
fuels, paint additives) and hazardous air pollutants (benzene, vinyl chloride, naphthalene).
EPA air quality scientists are conducting ongoing research to characterize landfill gases
using a variety of techniques to measure gas emission rates. One of these technologies,
optical remote sensing, uses the unique absorption of invisible light waves by pollutants
to identify and determine their concentration profiles—both vertically (to determine mass
flux) and radially (to identify hot spots). Research results have been published in a series
of EPA reports designed to assist municipalities in the management of the potential risk
of landfill gas explosions and risk to human health risk from inhalation of toxic
emissions. Research data will also be of help to EPA Regions, states, on-scene
coordinators, and others responsible for evaluating landfill gas emissions.
According to the intriguing EPA historical timeline, "Milestones in Garbage," the city of
Athens organized the Western world's first municipal dump 500 years before the
Christian era. In the years since then, municipal sold waste problems have loomed so
large that, in 2000, EPA established a link between solid waste emissions and global
climate change. In spite of this growing problem, municipalities often lack reliable, site-
specific data to manage health and safety risks, particularly for older landfills. EPA air
quality researchers in coordination with state, local, and regional regulatory authorities,
are providing the sound science needed to fill the data gaps that will identify landfill hot
spots and quantify mass emission rates for pollutants of concern. More than 30 air toxics
have been identified in landfill gas, but more site-specific data are needed to answer
questions such as: what data are adequate to develop representative emission factors, and
what are the best management practices for minimizing gas loss? Researchers are
working to answer these questions through the use of field measurements, optical remote
sensing with radial and vertical scans, analysis of raw landfill gas and combustion
byproducts, organo-mercury analysis (for the presence of metals in raw landfill gas), and
particulate-matter analysis.
Since 2003, EPA's Office of Research and Development landfill gas characterization
research has conducted measurements at 15 wide-area sites including municipal landfills,
wet/bioreactor landfills, Superfund landfills, and Brownfields (abandoned industrial
property). This work has resulted in a series of publications and workshops. Here is a
sampling:
- Landfill Gas Emission Model (LandGEM)-Software and Manual (EPA-600/R-05/047,
May 2005)
- Guidance for Evaluating Landfill Gas Emissions from Closed or Abandoned Facilities
(EPA-600/R-05/123)
- Three Case Studies Demonstrating U.S. EPA Guidance for Evaluating Landfill Gas
Emissions from Closed or Abandoned Facilities-Bush Valley Superfund Landfill,
Abingdon, Maryland (EPA/600/R-05/143); Rose Hill Regional Landfill, Kingstown,
-------
Rhode Island (EPA/600/R-05/141); and Somersworth Sanitary Landfill, Somersworth,
New Hampshire (EPA/600/R-05/142)
- First-Order Kinetic Gas Generation Model Parameters for Wet Landfills (EPA/600-R-
05/072)
- Measurement of Fugitive Emissions at a Landfill Practicing Leachate Recirculation and
Air Injection (EPA/600-R-05/088, June 2005)
Workshops and technology demonstrations based on this research have also been
presented to representatives from industry, academia, EPA regional offices, and state and
local governments. Applications of these research results will be of help to all specialists
with responsibility for evaluating landfill gas emissions, for land use policy decisions,
emission inventories, or for responding to applicable regulatory requirements.

Environmental Knowledge and Assessment Tool (EKAT)
(Courtesy of Jeff Heimermann and Tech Direct)
The development of the Environmental Knowledge and Assessment Tool (EKAT) was
funded by the U.S. Marine Corps. The goal of EKAT is to help remediation and
hazardous waste professionals save time and effort working on projects related to
remediation, brownfields, site characterization, hazardous waste, and clean up issues.
EKAT contains a wealth of centralized regulatory information. There are online tools to
screen chemicals for federal and state regulatory information, including CERCLA,
RCRA, CAA, and CWA. You can get NIOSH REL and OSHA PEL information for
chemicals in air. EKAT also includes Hazardous Waste Guides, Physical and Chemical
Properties Guides and Toxicology Guides to help with risk assessments. EKAT
summarizes, categorizes and links to highly useful resources on: major federal
regulations such as CERCLA and RCRA, as well as on environmentally pertinent topics
such as Coatings, Explosives Safety, the Federal Facilities Compliance Act (FFCA),
Military Munitions Rule (MMR), and Solvents Alternatives. Quick access to online
resources such as TOXNET, EPI Suite, and the Periodic Table increases efficiency in
finding information. Register on the EKAT demo site to test out the system.

Extending MNA and PRBs - AFCEE Assesses Abiotic Role in Enhanced In Situ
Bioremediation (From the Air Force Center for Environmental Excellence [AFCEE]
Technology Transfer Update)
As an extension to monitored natural attenuation (MNA) and enhanced in situ
bioremediation (EISB) of chlorinated solvents, AFCEE and its partners are investigating
the potential contribution of abiotic processes in these two successful site remediation
technologies. Coined by some as biogeochemical reductive dechlorination (BiRD),
AFCEE has investigated the potential for abiotic contributions at three Air Force sites as
part of its EISB initiative. Depending on the naturally occurring aquifer conditions,
levels of naturally occurring iron and/or sulfate were augmented to stimulate the
production of iron sulfides to stimulate BiRD at the sites.
These efforts are holding promise in extending the number of sites applicable to MNA
and EISB. The most recent results from AFCEE's abiotic efforts were presented at the
5th International Conference on Remediation of Chlorinated and Recalcitrant
Compounds in Monterey, CA, in May 2006. For more information regarding AFCEE's
MNA, EISB, and abiotic initiatives, contact the AFCEE Technology Transfer office.

Recent Conferences
Nanotechnology and OSWER - New Opportunities and Challenges - Symposium
July 12-13, 2006
Washington, DC
As we know, nanotechnology is more than a passing fad. This term, used to define a
broad range of disciplines, can be summed up as the use or manufacture of extremely
small particles for application to products or processes. The field offers huge technical
gains, business opportunities, and the road to improved products. But it also poses a
number of challenges to regulatory agencies, including EPA, because of potential
environmental impacts, both human health and ecological. An EPA OSWER
Symposium was recently held to help EPA better understand these new issues, and ask
-------
the right questions before applying any regulations to industry. EPA has been involved
with nano to some degree already, but is trying to learn all it can and at the same time, be
cautious about these future challenges. The symposium offerings included the following
session topics:
Life Cycle of Nanomaterials
Potential Exposure Scenarios and Potential Toxicity of Nanomaterials
Detection and Characterization of Nanomaterials in the Environment
Fate and Transport of Nanomaterials
Waste Management of Nanomaterials
Review of Regulations, Positions, Policies, Guidance and Actions for Nanomaterials
Proceedings are not posted yet, but if interested, I can get those to you when they are
available (gill.michael@epa.gov).
Battelle Conference On Remediation Of Chlorinated And Recalcitrant Compounds
May 22-25, 2006
Monterey, CA
A number of EPA folks attended this widely attended annual conference back in May.
With 7 concurrent sessions, there were many topics to choose from over the duration of
the conference. Below is a list of some of the topics covered. More information, as seen
through the eyes of some EPA colleagues, can be found in this white paper available at
this EPA intranet website (sorry, no access for non-EPA folks):
http://intranet.epa.gov/ospintra/scienceportaVsource/NOTES%20FROM%20BATELLE%20CONFERENCE.pdf.
In this white paper, they discuss what they heard on the following topics:

NARPM Annual Conference
June 19-23, 2006
New Orleans, LA
The National Association of Remedial Project Managers (NARPM) held its annual
conference in New Orleans from June 19th-23rd. It was held in conjunction with the
Technical Support Project and the Branch Chiefs meetings. As usual, the NARPM
meeting offered many useful topics through panels, papers and information sessions. A
small subset of the available offerings included the following (which I attended):
DNAPL Remediation
Wastewater Treatment Fundamentals
Remedial Technologies Overview
Post-Construction of Ground Water Remedies
Vapor Intrusion - Assessment Update
Design and Construction Issues
Along with Region 4's HSTL, Felicia Barnett, I provided an update on the HSTL
program to the Ground Water Forum. I also presented during a plenary session on
various online resources in a talk titled: "Hazardous Waste Cleanup Technology
Resources". Presently, these materials can be viewed at the following web address:

Technical Support Available from US Army Corps of Engineers
In the world of tech support, we in Superfund are very fortunate. We have assistance
from our in-house regional tech support, the ORD labs (I can help with that!), as well as
contractual help. Recently, I found out that we have one other possible option with
support from the US Army Corps of Engineers. Ken Skahn of EPA HQ recently sent out
a notification that Superfund technical support is available from the Army Corps of
Engineers. He is the Superfund program's liaison to the Corps. This is support available
at no-cost to EPA RPMs. It should be said that to avoid any potential conflict-of-interest,
this support only makes sense for non-DoD sites and where the Corps is not already
involved in some capacity.
-------
The type of assistance that the Corps is offering covers 5-year review reports. Value
Engineering policy. Direct Cite contractor payment policy, real estate acquisition, etc.
The EPA/Corps web sites below explain the wide variety of technical support and Ken is
willing to assist you if have any questions. He can be reached at 703-603-8801. Thanks
for the tip, Ken!

Value Engineering in Superfund
Back in April, a memo below was signed by Superfund Office Director Mike Cook,
which reaffirmed the Superfund program's policies on value engineering at Fund-lead
Superfund sites. The memo outlined when a value engineering study should be
completed and when a value engineering screen should be conducted. If you have
questions on implementation of this policy, the OSRTI staff expert is Ken Skahn. Ken
can be reached at (703) 603-8801 and e-mail skahn.ken@epa.gov.
Value Engineering (VE) is a highly beneficial technique used to reduce nonessential
procurement and program costs. VE uses systematic and creative methods to reduce costs
without sacrificing the reliability, efficiency, or original objectives of the project. In
accordance with a federal (FAR) requirement, all RA and Long Term RA (LTRA)
contracts above $100,000 should contain Value Engineering Change Proposal (VECP)
provisions. These VECP provisions afford contractors a substantial financial incentive
(roughly 50%) for cost savings proposals that are accepted by the government and
incorporated into a project. Compared to the 100% VE cost savings during RD, the
government will then be the beneficiary of somewhat less than 50% of the VE cost
savings during RA.

LOCAL NEWS
Technical Information Exchanges on Landfill Closure in Region 9
(With assistance from ORD's Ken Sala)
One of the landfills discussed, the
Operating Industries Landfill, California
Following a general request, two informal information exchange meetings were
recently held in Region 9 on the topic of closure practices at landfills. Both meetings
were technical in nature. Regional staff worked together to identify landfill issues
and generate questions for discussion. We had phone attendance by ORD
researchers, non-EPA landfill experts and staff from the Office of Solid Waste and
Emergency Response (OSWER). This allowed the Region 9 attendees a unique
opportunity to ask direct questions of experts and get direct feedback in a small
setting.
In the first meeting, ORD researchers Dave Carson, Thabet Tolyamet, and Steve
Rock, along with Kelly Madalinski of EPA's Office of Superfund Remediation and
Technology Innovation discussed current ORD research and guidance, including the
long term performance guidance, released in 2002:
Assessment and Recommendations for Improving the Performance of Waste
Containment Systems, December 2002
http://www.epa.gov/ORD/NRMRL/pubs/600r02099/600r02099.htm) .
The presenters discussed how ORD is presently working on these issues: performance
of GCLs and cover systems; National Academy of Science / OSWER collaboration
on examination of waste containment systems; land-filling of construction demo
material in Region 5; and work with the ITRC on bioreactors and alternative covers.
Region 9 staff discussed eleven different landfill sites where closure presented
challenging technical issues.
-------
Group interest then turned to whether ORD had catalogued observed failures of
landfill covers, liners and how this would be very helpful and applicable to 5-year
reviews and performance monitoring design. Since pressure to redevelop closed
landfills has become a driver on Regional responses to landfills, it was determined
that the next technical session should focus on how to avoid failure in landfill closure.
A second meeting focused on technical and financial challenges, financial assurance,
cap aging, and clean closure. These are the issues that environmental professionals
see as the biggest challenges for avoiding failures at closing landfill sites. In addition
to the EPA experts at the first meeting, we were fortunate to have two non-EPA
landfill experts provide assistance. They were Ed Kavazanjian of Arizona State
University and Greg Richardson of G.N. Richardson Associates, Raleigh, NC.
In these technical information exchanges, we were able to develop a greater
understanding of the dynamics of landfill closure and start to think about how to
respond to the Region's aging landfills. No proceedings are available from these
meetings, but if you would like to discuss them in more detail, don't hesitate to
contact Mike Gill (gill.michael@epa.gov).
Superfund Basic Research Program:
Phase II GAC Microwave Regeneration System
In mid-May, Region 9 reps visited the McClellan Park site in Sacramento (the former
McClellan Air Force Base) to see a technology demonstration that is being funded by the
Superfund Basic Research Program out of the National Institute of Environmental Health
Sciences (NIEHS). The technology uses microwaves to regenerate carbon used in an
SVE system. This was a process that some folks saw as a Phase I study back a couple of
years ago, both in late 2003 and in October, 2004 as part of the field trip during the
Superfund Tech Support Project meeting in Sacramento. The system has since been
scaled up as a Phase II and now has more throughput and is mobile. The next step for the
developer is to try and commercialize the unit, either through selling services to sites or
as a stand-alone system for sale.
From the abstract: "The main objective of the SBIR Phase II work in the first year was to
design, construct and test a field-ready mobile 50 kg/hr microwave carbon regenerator. In
the second year the prototype microwave reactor system will be transported to three
selected sites and operated to demonstrate that the microwave technology is a cost-
effective commercial solution for recovering VOCs from a number of different sites.
Using the field demonstration test results, technical and economic feasibility of the
microwave technology will be assessed."

In summary, the technology:
- can regenerate carbon at a rate of 100 pounds per hour,
- allows for carbon reuse,
- avoids incineration and disposal,
- is portable (on a trailer truck bed),
- allows liquid recovery from the GAC, and
- appears to be cost beneficial, as calculations have shown that at $0.63/lb., it is about 1/3
the cost of a standard carbon changeout.
Here is a link to a number of photos that were taken that day at the technology demo:
http: //share. shutterfly. com/acti on/wel come? si d=8 AZNmz Ji 3 aNm Jv
Questions were posed regarding emissions from the system. The developer said that "the
mobile microwave unit does not have any air emissions, therefore, there is no way for air
emissions to be tested. The VOC gases and nitrogen gas are contained in the outlet gas
from the microwave regeneration reactor. The VOC gases are condensed and separated
in the liquid knockout pot. After VOC gases are condensed, nitrogen is recycled back to
the microwave reactor. The liquid is drained from the collection vessel. Since the system
is completely enclosed, there are no emissions."
Regarding tests on the regenerated carbon, the question was asked what you typically see,
and what are you aiming for with respect to a particular iodine or butane number as a
measure of activation level? They "measure the iodine number and adsorption capacity
of the regenerated carbon. The developer would like to see the working adsorption
capacity of regenerated carbon remains at the same values, close to the fresh carbon, as
the regeneration cycle increases. The iodine number of the regeneration carbon should
be greater than the 600 m2/g that will provide a complete removal of VOCs and other
hydrocarbons from SVE gas. "

Pilot Tests Lead to Expanded ISCO for Vadose-Zone Remediation
(Courtesy of Technology News and Trends, July, 2006)
Following successful pilot-scale field testing of in-situ chemical oxidation (ISCO) in
2001, the USAF began an expanded-scale application in 2003 to remove chlorinated
solvents from an upgradient source area at Air Force Plant 44 in Tucson, AZ. [For
information on site conditions and details concerning the pilot test, see the January 2003
issue of Technology News and Trends.] During both the pilot and expanded operations,
potassium permanganate solutions were injected to remove residual high concentrations
of TCE from fine-grained alluvial sediments in the upper part of the regional aquifer.

CLU-IN Issue Areas
A new Issue Area feature has been added to CLU-IN. EPA understands that site owners
and other parties involved in remedial activities need information on emerging issues.
CLU-IN Issue Areas bundle available information associated with selected topics. They
draw upon existing resources from the CLU-IN Web site, but also from other sources of
information that were not previously cited or available on CLU-IN. These topics are still
being researched, and these issue areas will be updated with information from federal
cleanup programs, state sources, universities, nonprofit organizations, peer-reviewed
publications, and public-private partnerships. They welcome any suggestions you may
have for new topics or additional resources. Currently the Issue Areas include sections
on DNAPLs, Mining sites, Nanotechnology, Sediments, Vapor Intrusion and Wood
Treater sites.

Triad project profiles contain information about completed and ongoing applications of
the Triad at contaminated sites. Triad project profiles describe sites that use the elements
of the Triad: systematic planning, real-time monitoring and measurement technologies,
and dynamic work strategies. While the focus of the profiles is on sites that demonstrated
all three components of the Triad, some of these sites exhibited only one or two aspects
but are still useful examples. The Triad project profiles provide a summary of relevant
site information, contaminants and media, project goals and outcomes, cost and time-

savings, detailed information on the Triad work performed at the site, as well as points of
contact and electronic references. Five new profiles have been recently added.

Dry Cleaner Virtual Tour
This slide presentation was developed by the State Coalition for the Remediation of
Drycleaners. Spent drycleaning solvents have been found in soils and ground water in
approximately three-quarters of existing or former dry cleaning facilities. Because these
contaminants are difficult to remove, they present a substantial environmental challenge.
You can take a virtual tour of the dry cleaning process which includes the cleaning and
recycling of used cleaning solvents.
