2.0 STATEMENT OF BASIS AND PURPOSE
The selected remedy for Operable Unit 1 (OU1), Spill Sites 1-7 (SS 1-7), at F.E. Warren
Air Force Base (Base), in Cheyenne, Wyoming is NO ACTION. The selected action, the third
at the Base, was chosen in accordance with the Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA), as amended by the Superfund Amendments and
Reauthorization Act of 1986 (SARA), and the National Oil and Hazardous Substances Pollution
Contingency Plan (NCP). The selected remedy addresses only risks associated with soils at OU1,
SS 1-7. This decision is based on the Administrative Record for the site. The United States
Environmental Protection Agency (EPA) and State of Wyoming Department of Environmental
Quality (WDEQ), as oversight agencies, concur with the selected remedy. The United States Air
Force is the lead agency for the site.
3.0 DESCRIPTION OF SELECTED REMEDY
The selected remedy for OU1, SS 1-7 is that no remedial action is required for the soils at the
spill sites. Any ground water contamination at the spill sites will be investigated during OU2.
OU1 is the third often operable units to be investigated under terms of the Federal Facility
Agreement (FFA). The others are: OU2 - Facility Ground water; OU3 - Landfills 3 and 6; OU4
- Acid Dry Wells; OU5 - Fire Protection Training Area (FPTA) 2; OU 6 - Open Burning/Open
Detonation Area; OU7 - Firing Range(s); OU 8- Landfill 5; OU9- Landfills 2 and 4; and OU10-
Landfill 7 and Fire Protection Training Area 1. All of the investigations are being conducted in
accordance with the FFA. It is anticipated that the Record of Decision (ROD) for OU2 will be
issued after the remedial investigation (RI) has been completed for the other operable units.
4.0 DECLARATION STATEMENT
The United States Air Force (USAF) has determined, with the concurrence of the
Environmental Protection Agency (EPA), and the State of Wyoming (WDEQ), that no remedial
action is required for the soil at Spill Sites 1-7. The Baseline Risk Assessment (BRA) conducted
in 1994, as part of the remedial investigation concluded that contaminants left in the soil pose no
significant risk to human health or the environment. The BRA did not address ground water.
Potential impacts to ground water from contaminants remaining in the soil at Spill Sites 1-7 will
be investigated under OU2. Additional discussions regarding considerations made in arriving at
this decision are contained in the Ty/-.i

DECISION SUMMARY FOR THE RECORD OF DECISION
SPILL SITES 1-7, OPERABLE UNIT 1
1.0 SITE NAME, LOCATION, AND DESCRIPTION
F. E. Warren Air Force Base (Base), occupies approximately 5,866 acres immediately
adjacent to the west side of the City of Cheyenne, Wyoming .
The Base was placed on the National Priorities List on February 21, 1990. Historically,
the Base has served a number of military functions, including; cavalry outpost, quartermaster
depot and intercontinental ballistic missile operations base. Operations began at the U. S. Army
outpost named Fort D. A. Russell in 1867. The name was changed to Fort F. E. Warren in 1930.
The Base was a major training facility during and after World War n. Fort F. E. Warren was
transferred to the newly formed U. S. Air Force in 1947 and was subsequently named F. E.
Warren Air Force Base. The Base underwent extensive renovation after World War n. The
majority of the Army training facilities were torn down and not replaced. Construction since that
time has centered on facilities for Air Force operations. Beginning in 1958, F. E. Warren Air
Force Base became a Strategic Air Command (SAC) base. Since then, F. E. Warren Air Force
Base has served as an operations center for, first, the Atlas Intercontinental Ballistic Missile
(ICBM), followed by the Minuteman I and m and finally, the Peacekeeper (MX) ICBMs. The
Base was part of Air Combat Command (ACC) from 1992 to 1993, and in July 1993, became part
of Space Command.
F. E. .Warren Air Force Base is bordered by agricultural land and rural or suburban
residential areas. The Base contains 831 residential housing units and several unaccompanied
personnel housing units (barracks), along with the services required by residents.
2.0 SITE HISTORY AND ENFORCEMENT ACTIVITIES
Operable Unit 1 (OU1) consists of seven separate sites (SS 1-7) located in the central and
southern parts of the base (Figure 1). OU1 is the third often operable units for which RODs will
be prepared. These sites consist of areas where hazardous materials have been spilled or disposed
of. These sites include underground storage tanks (UST's), material storage areas, oil/water
separators, and a battery acid disposal site. A detailed description of the sites follow in section
5.0
On September 26, 1991, a Federal Facility Agreement (FFA) was signed between the
USAF, EPA, and WDEQ. The FFA is required by Section 120 of CERCLA. The FFA provides
the framework for EPA and WDEQ oversight of continuing remedial investigations at the Base
and further identifies USAF investigation activities and schedules. F. E. Warren Air Force Base
submits work plans and reports to EPA and WDEQ for review and concurrence, in accordance
with the FFA.

3.0 HIGHLIGHTS OF COMMUNITY PARTICIPATION
The USAF has prepared and implemented a community relations plan (CRP) in
accordance with CERCLA requirements, and the FFA. The CRP describes community
involvement activities the USAF will undertake during remedial activities at F. E. Warren
Air Force Base. The USAF has followed the requirements of the CRP, including issuance
of periodic fact sheets, holding public meetings, and providing the opportunity for public
comment on the Proposed Plan throughout the OU1 investigation.
The Administrative Record has been established at an on-base location and at the
Laramie County Public Library. The USAF has prepared and distributed fact sheets to all
persons or groups identified on the CRP mailing list (approximately 700 members). In
addition, the Proposed Plan for OU1 was briefed and copies of the plan were passed out
to the Restoration Advisory Board on February 21, 1995.
The announcement of the commencement of the public comment period was made
on February 26, 1995, through advertisements in the Wyoming Tribune-Eagle and in the
Casper Star-Tribune. These advertisements announced and outlined the public comment
period and public meeting. The public comment period was scheduled from March 12 to
April 11,1995. A public meeting was held at Cheyenne, Wyoming on March 28, 1995.
Several verbal comments were presented and are summarized in the official transcript of
the meeting. The transcript has been placed in the Administrative Record.
In addition to the newspaper announcements, the USAF issued press releases which
resulted in articles published in the Casper Star-Tribune on 14 March 1995 and Wyoming
Tribune-Eagle on March 12, 1995. An article appeared in the Base Sentinel Paper on
March 17, 1995, The Channel 5 KWGN television station interviewed base personnel
about the Proposed Plan for OU1 on 9 March 1995. KRAE radio carried public meeting
announcements periodically throughout this time period.
Responses to all comments on the Proposed Plan- are presented in the
Responsiveness Summary of this ROD.
4 .0 SCOPE AND ROLE OF OPERABLE UNIT 1
F. E. Warren Air Force Base has been divided into ten operable units (OUs). These
are: OUl-SpUl Sites; OU2-Facility Ground Water; OUS-LandfiUs 3 & 6; OU4-Acid Dry
Wells; OU5-Fire Protection Training Area 2; OU6-Open Burning/Open Detonation Area;
OU7-Firing Range(s); OU8-Landfill 5; OU9-Landfills 2 and 4; and OUlO-Landfill 7 and
Fire Protection Training Area 1.
OU1 is the third of the ten OUs to be investigated under the FFA. The OU1
Baseline Risk Assessment (BRA) demonstrated no significant risk to human health or the
-------
environment from the contaminants found in the soil at this OU. Soil contaminants at the
spill sites, as potential sources of ground water contamination, will be investigated and
possibly remediated during OU2. The ground water beneath the spill sites will also be
investigated during OU2.
5.0 SITE CHARACTERISTICS
F. E. Warren AFB (Base) is located in south-central Laramie County in
southeastern Wyoming near the western edge of the City of Cheyenne. The adjoining part
of the Base consists of approximately 6,000 acres. The Base was listed on the National
Priorities List in 1990. Due to the complex nature of contamination, the Base has been
divided into ten Operable Units, or study areas.
SPELL SITE 1
In 1973 the Base service station, building 400, experienced an estimated loss of
2,000 - 2,500 gallons of leaded MOGAS (motor gasoline) over a period of 6 months.
Gasoline vapors were detected in the Non-commissioned Officers (NCO) Club (building
401) and in a field east of the NCO Club. A storage tank was found to be the source of
the leak and was replaced. Some fuel recovery was attempted. Other spills might have
taken place after the gasoline leakage in 1973. An above-ground waste-oil tank with a
concrete containment berm was another source of contamination. Waste oil entered the
surrounding soil through fractures in the concrete berm before the tank was removed in
1989. A third source of contamination was a 500-gallon underground storage tank east of
building 400. This storage tank was removed in 1990. The tank was empty when
removed, but it is uncertain whether any contaminated soil was removed.
SPELL SITE 2
In September, 1983 the contents of approximately thirty 55-gallon drums, which
were stored at the south end of the lot south of building 810, were dumped on the ground.
These drums were thought to contain only water at the time they were dumped. However,
the drums contained residues of hydraulic fluid and motor oil. Most of the liquid flowed
down East Street, adjacent to the lot, and was recovered. The two waste accumulation and
storage points which are also located in the lot south of building 810 have experienced
numerous spills of oil and hydraulic fluid. One accumulation point is located just south
of building 810 and consists of a 300-gallon waste oil tank and several 55-gallon drums.
Although the tank is in a concrete dike, the ground around the tank is heavily stained with
oil. The second accumulation point is located at the southern end of the lot and consists
of several 55-gallon waste oil drums. The ground around these drums is also stained.
SPELL SITE 3
Spill Site 3 was the disposal site for used battery acid from building 338, a battery
shop. In April, May, and June 1980, an estimated 150 gallons of used battery acid (50
gallons per month) were disposed of by pouring the acid on the ground west of building
338. In 1990, Base personnel provided additional information, clarifying the location of
-------
the spills at Spill Site 3. Two 10-foot-deep dry wells west of building 338 were identified
as disposal points for the used battery acid.
SPILL SITE 4
In October, 1982 pin hole leaks in a drum of trichloroethene (TCE) were discovered
at building 1250. An estimated 15-20 gallons of TCE were spilled. Soil tests were made
to determine the extent of soil contamination and 530 cubic yards of contaminated soil
were removed. Three wells were installed in the area. Elevated concentrations of TCE,
chloroform, and other organic contaminants were detected in the ground water samples
taken from these wells. The source of the ground water contamination will be investigated
during the Operable Unit 2, base ground water remedial investigation.
SPILL SITE 5
The waste oil accumulation point east of Building 336 was identified as Spill Site
5. There were two 200-gallon tanks located in a fenced area of the parking lot. One
contained used oil and the other contained waste antifreeze. Also contained in the fenced
area were several 55-gallon drums which contained waste and clean oil. The area has been
in use since approximately 1962 and there is visual evidence of oil spills.
SPILL SITE 6
Spill Site 6 is the waste accumulation point located in the courtyard of Building 316
and the yard south of Building 316 which was used as a radiator cleaning area. The
courtyard has been used as an accumulation point by Power Production since at least 1962
where drums of new and waste oil were stored. Numerous oil spills have reportedly
occurred in the courtyard. Until 1982 waste battery acid was also dumped on the ground
in the courtyard. The courtyard area has been covered with topsoil and gravel. The
Power Production shop has recently moved to another building.
SPILL SITE 7
Building 1294 (formerly building 4000) was used from 1960 to 1966 as a
liquid-oxygen production facility for Atlas missiles. Organic solvents (primarily TCE)
were used extensively in the facility as degreasers to prevent the oil and grease from
reacting explosively with the pure oxygen. The grease trap was a subsurface concrete
structure designed to separate oil and grease from water by trapping the floating oil and
grease, while discharging the water beneath to a drain leading north to Diamond Creek.
Trap doors on top of the structure allowed the floating oil and grease to be skimmed off.
Even though the use of the facility as a liquid-oxygen production center was stopped in
1966, water was discharging from the grease trap at a rate of approximately 0.5 gallons
per minute in 1987. According to Base personnel, the source of this water was from
flow-through air conditioning units in building 1294. Discharge of water to the grease trap
was discontinued in 1988; however, flow was accidentally allowed for a brief period in
1989. By this time, the original discharge lines from the grease trap were plugged so that
water overflowed through the trap doors spilling a layer of oily sludge from the bottom of
-------
the grease trap out onto the surface. The water was also highly contaminated with TCE.
The grease trap, sludge, and some surrounding soil were excavated in 1989. The
excavated materials were delivered to USEPA-approved disposal sites.
REMEDIAL INVESTIGATION FINDINGS
Soils at the Spill Sites were investigated for contamination from 1985 to 1990 under
the United States Department of Defense's Installation Restoration Program. In 1992 and
1993, further investigations of the sites were conducted under the current CERCLA
remedial investigation.
A complete listing of all constituents tested for and the contaminant(s)
concentrations can be found in the Remedial Investigation Report for Operable Unit
1 (September 30, 1994) located, in the Information Repository at the Laramie County
Library.
6.0 SUMMARY OF SITE RISKS
As part of the remedial investigation, the USAF prepared a Baseline Risk
Assessment (BRA) which evaluated the risks associated with exposure to soils
contamination at Spill Sites 1-7. The BRA consisted of human health and ecological risk
assessments, including the identification of contaminants of concern, exposure assessments,
toxicity assessments, risk characterization, and uncertainty analysis. The BRA evaluated
risks associated with soil contamination only. Risks associated with contaminants present
in ground water, surface water, and streambed sediments will be evaluated in the OU2
BRA.
Appendix H of the Remedial Investigation (RI) Report describes the results of the
BRA in detail. A Fact Sheet on the BRA. at OU1 was made available prior to and at the
public meeting which was held on March 28 1995.
RESULTS OF THE BASELINE RISK ASSESSMENT
SPILL SITE 1
The BRA indicated unacceptable future health risks associated with exposures to
hexavalent chromium by inhalation. However, the risks are likely to be substantially
overestimated because of the assumption that all chromium in soil is hexavalent, and that
in the future subsurface soil will be brought to the surface to generate airborne particulates.
It is unlikely that one-hundred percent ( as assumed in the BRA) of the chromium detected
at Spill Site 1 is in the form of hexavalent chromium. The ecological risk assessment
found no indication that adverse effects would occur to biota at Spill Site 1. There are no
unacceptable non-carcinogenic risks associated with Spill Site 1. .
-------
SPELL SITE 2
No unacceptable health or ecological risks were found to be associated with
contaminants in the soil at Spill Site 2. The calculated non-cancer hazard indices for
surface and subsurface soil under both current and future exposure scenarios are less than
1.0. This indicates that adverse non-cancer effects are not likely to be associated with this
site. No indication of substantial adverse ecological effects of chemical contamination
were found at spill site 2.
SPILL SITE 3
No unacceptable health or ecological risks were found to be associated with
contaminants in the soil at Spill Site 3. The calculated non-cancer hazard indices for
surface and subsurface soil under both current and future exposure scenarios are below 1.
This indicates that adverse non-cancer effects are not likely to be associated with this site.
SPELL SITE 4
Exposures to contaminants in surface and subsurface soils were associated with
estimated lifetime cancer risks within or below the EPA target risk range. The EPA target
risk range is defined as: an increase of one cancer case in one million to one in ten
thousand exposed individuals. The calculated non-cancer hazard indices for all exposed
populations at spill site 4 were less than 1.0, the level at which there is concern over the
occurrence of adverse health effects. The ecological risk assessment indicated significant
differences in vegetation patterns between spill site 4 and a control area. However, these
differences were attributed to natural variation or human intrusion, and were not
considered to be associated with site chemical contamination.
SPELL SITE 5
No unacceptable health or ecological risks were found to be associated with
contaminants in soil at Spill Site 5. Therefore, no cancer or non-cancer risks are predicted
to occur under the current or future exposure scenarios. The ecological assessment for
spill site 5 also predicts that no adverse ecological effects are likely to occur due to site
contamination.
SPELL SITE 6
At spill site 6, all of the cancer risks calculated for the current land-use scenario
were below the lower end of the EPA target risk range. All non-cancer hazard indices for
current exposures were also below a level that would indicate the potential occurrence of
unacceptable non-cancer effects. All of the future scenario cancer and non-cancer risk
estimates associated with exposures to surface and subsurface soils are at or below the
lower end of the EPA target risk range. The ecological assessment likewise indicates that
no significant adverse effects on biota are likely to be associated with soil contamination
at spill site 6.
-------
SPILL SITE 7
Under current exposure conditions for spill site 7, exposures to surface soils are
associated with an estimated cancer risk below the EPA target risk range. The risks are
associated primarily with exposures to chromium and arsenic. Similarly, future adult
residential risks are at the lower end of the risk range. These risks are likewise due to
chromium and arsenic exposures. None of the current or future pathways, either
individually or in combination, are associated with hazard indices approaching 1.0. Thus,
no adverse non- cancer effects are predicted to occur associated with surface or subsurface
soil contaminant exposures at spill site 7. The ecological evaluation found no differences
in vegetation between spill site 7 and a control transect. In addition, the ecological risk
assessment found no indication, on toxicological grounds, that site contamination would
result in adverse effects on biota.
UNCERTAINTY WITHIN TEE RISK ASSESSMENT FRAMEWORK
A degree of uncertainty is associated with all BRAs. _This uncertainty is based on
a number of factors, such as:
Limited toxicological data on the contaminants of concern;
Difficulties of predicting future exposure scenarios;
One factor contributing to uncertainty in the Spill Sites risk assessment concerns the
way in which the predominant contaminants found in soil at the sites were handled. These
contaminants were identified generally as total petroleum hydrocarbons (TPH) instead of
being separated into individual petroleum hydrocarbon compounds. The toxicological
effects from TPH contamination could only be determined qualitatively for the spill sites.
For this reason, the toxicological effects from TPH contamination at the spill sites could
be determined from a qualitative standpoint only. However, components of fuels
commonly known to cause adverse health effects either:
Were not present in concentrations high enough to contribute to
unacceptable health risks,
Were present at elevated concentrations in such small areas that
significant exposures would be unlikely, or
Were not detected at all.
Total petroleum hydrocarbons, in addition to other soil contaminants, at the Spill
Sites will be evaluated as sources of ground-water contamination during OU 2 (base-wide
ground water) investigations. Total petroleum hydrocarbons are not addressed under
CERCLA, unless commingled with CERCLA hazardous substances.
-------
7.0 EXPLANATION OF SIGNIFICANT CHANGES
The Proposed Plan was released for public comment in March 1995. The preferred
alternative was that no remedial action is needed for soils and that this action is protective
of human health and the environment. The USAF, EPA, and WDEQ reviewed all written
and verbal comments submitted during the public comment period. It was determined that
no significant changes were necessary to the preferred alternative in the Proposed Plan,

OPERABLE UNIT 1
INTRODUCTION
The responsiveness summary is organized into sections as follows:
A. Overview
B. Background on Community Involvement
C. Summary of Comments Received
D. State Concerns
E. Attachment: Community Relations Activities at F.E. Warren Air
Force Base.
A. OVERVIEW
At the time of the public comment period, the preferred alternative for Spill Sites
1-7, Operable Unit 1, at F. E. Warren Air Force Base, had been selected by the Air Force,
with EPA and Wyoming DEQ concurrence and was presented in the Proposed Plan. The
preferred alternative is that no remedial action is required.
Based on the public's response and comments received during the public comment
period, there are no objections to the preferred alternative.
B. BACKGROUND ON COMMUNITY INVOLVEMENT
Community interest in CERCLA/IRP (Installation Restoration Program) activities
at F. E. Warren Air Force Base has waxed and waned over the years since the records
search and interviews conducted by Engineering Science for the Air Force in September
1985. No specific individuals or organizations have been consistently involved over this
period, although numerous groups and persons have been involved from time to time.
There were no concerns expressed during the OU1, Spill Sites 1-7 , Remedial
Investigation, prior to the public comment period.
C. SUMMARY OF COMMENTS RECEIVED
The public comment period on the Proposed Plan for Spill Sites 1-7, Operable Unit
1, at F. E. Warren Air Force Base was held from March 12 to April 11, 1995. Also, a
public meeting was held on March 28, 1995. No comments were received either in
writing or in person from the public.
-------
D. STATE CONCERNS
The following are the comments received by the Wyoming Department of
Environmental Quality.
TPH has been detected in soils at concentrations considered by the state to
be significant at Spill Sites 1,2,5 and 6. It is the state's intent to pursue remediation
of this contamination in soils at the spill sites either as sources of ground water
contamination during Operable Unit 2 or as actions taken outside the jurisdiction of
CERCLA due to the petroleum exclusion contained in CERCLA.
In addition to TPH, a number of soils contaminants present at the spill sites
are impacting or have the potential to impact ground water, specifically at Spill
Sites 1, 6, and 7. These contaminants will also be addressed during Operable Unit
2 activities and will be better assessed when a reliable background data set for
inorganic constituents in soils and ground water has been established. In addition,
it is the state's position that the evaluation of these contaminants as existing or
potential ground water pollutants is within the scope of the Operable Unit 2.

ATTACHMENT A
COMMUNITY RELATIONS ACTIVITIES
At
F.E. WARREN AIR FORCE BASE
OVERVIEW
The unique community involvement needs of F. E. Warren Air Force Base
IRP/CERCLA activities are addressed in the Community Relations Plan (CRP). In late
1990, during plan development, interviews were held with 56 people representing F. E.
Warren Air Force Base, other Federal agencies, State, city and county agencies,
community groups, well owners, and other individuals. The most significant issues
identified in the interviews were concerns about potential drinking water contamination and
about the community involvement process.
ADMINISTRATTVE RECORD and INFORMATION REPOSITORY
An Information Repository and an Administrative Record containing documentation
of the IRP/CERCLA process were established in October 1989 and are maintained at the
following locations to insure accessibility.

MAILING LIST
A major part of the public relations activities is the mailing list. In an attempt to
proactively contact the 2,300 well owners identified in the EPA Superfund ranking, F. E.
Warren sent a general mailing to well owners within a 3-mile radius. The Wyoming State
Engineer's Office provided the mailing list of well owners. The mailing included a brief
status report and a coupon to be mailed back if the well owner wanted to be added to the
mailing list for distribution of later status reports. This activity resulted in the current list
that has about 700 names on it. The mailing list is maintained in the F. E. Warren Air
Force Base Public Affairs Office. Status Reports or Fact Sheets are mailed on a quarterly
basis. Anyone who desires to be included on the list should contact either of the following

OU1 RELATED ACTIVITIES
Operable Unit 1 has been addressed in Fact Sheets, Status Reports, newspaper
advertisements and articles since Fact Sheet 1 was prepared, by the Air Force, in October
1990 for the initial interviews. Fact Sheet 1 was mailed in May 1991. After the Federal
Facility Agreement became effective, a Status Report update has been distributed quarterly
beginning December 12, 1991, with information on all of the operable units. The most
recent update was sent out to the mailing list in March 1995.
The Proposed Plan for OU1 was prepared in February, 1995. A display advertisement
concerning the Proposed Plan and the public meeting was placed in the Wyoming
Tribune-Eagle and the Casper Star-Tribune on February 26, 1995 and a copy of the
Proposed Plan was sent to all persons on the mailing list. A copy of the Proposed Plan
was placed in the Administrative Record and the Laramie County Library Information
Repository on March 10, 1995. All of the newspaper advertisements and the mailings
were coordinated between the Air Force, EPA and Wyoming DEQ before publication or
distribution. In addition to the paid advertisements, the Air Force issued press releases
which resulted in articles published in the Wyoming Tribune-Eagle on March 12, 1995,
the Casper Star-Tribune on March 14 1995, and the F. E. Warren Air Force Base Sentinel
on March 17, 1995. An interview with base personnel about OU1 was aired on March 9,
1995 by Channel 5, KGWN television. KRAE radio made periodic announcements during
this time about the public meeting.
