16. Abstract (Limit: 200 words)
The 25-square-mile New Brighton/Arden Hills site includes the 4-square-mile Twin
Cities Army Ammunition Plant (TCAAP) in Ramsey County, Minnesota. Land use in the
area is predominantly residential with commercial and industrial sectors. The
estimated 100,000 residences, located within 2 miles of the site, along with adjacent
townships use various glacial and bedrock aquifers as their drinking water supply.
The TCAAP facility, a small arms manufacturing facility, is currently operated by the
Federal Cartridge Company (FCC) and used by two manufacturing lessees, Alliant
Techsystems and 3M Corporation. Since 1941, the plant has manufactured, stored, and
tested small arms ammunition and related materials. From 1941 to 1981, waste
materials, which included VOCs, heavy metals, corrosive materials, and explosives,
were disposed of at 14 source areas located within TCAAP. In addition, breaks and
leaks in sewer lines, where other disposal occurred, may have contributed to onsite
and offsite ground water and soil contamination. In 1981, state investigations of
municipal and private drinking water wells in and around TCAAP identified
contamination of ground water, onsite soil, sediment, and surface water by VOCs, other

organics, and metals. Past removal actions and seven previous RODs, signed from 1983 to
1989, addressed interim remedial actions conducted by the Army and Alliant Techsystems
and provided for the establishment of alternate drinking water supplies for surrounding
communities, onsite in-situ soil vapor extraction; installing ground water pump and treat
systems to remediate ground water onsite; boundary ground water recovery systems to
prevent further migration of VOCs; thermal treatment of PCB-contaminated soil, and the •
cleaning, repairing, and testing of contaminated sewer lines. This ROD addresses
remediation of the south plume of offsite contaminated ground water, as OU3. Future RODs
will address the offsite north plume of contaminated ground water, as OU1, and the onsite
soil, sediment, surface water, and ground water, as OU2. The primary contaminants of
concern affecting the ground water are VOCs, including benzene, TCE, and xylenes; other
organics, including phenols; and metals, including chromium and lead.
The selected remedial action for this site includes pumping and offsite treatment of
contaminated ground water at the leading edge of the south plume using precipitation and
filtration to remove inorganic solids and a pressurized granular activated carbon system
to remove VOCs; discharging the treated ground water offsite to the potable water supply
of the City of New Brighton; disposing of filtration residuals and spent carbon offsite;
implementing institutional controls including ground water use restrictions; and
monitoring ground water. The estimated present worth cost for this remedial action is
$4,851,000, which includes an annual O&M cost of $276,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up standards, which are based on state Standards and
SDWA MCLs and MCLGs, include 1,1-dichloroethane 70 ug/1; (state); l,1-dichloroethene
6 ug/1 (state); cis-l,2-dichloroethene 70 ug/1 (MCL); 1,1,1-trichloroethane 200 ug/1

I. DECLARATION FOR THE RECORD OF DECISION
A. site Name and Location
New Brighton/Arden Hills (NB/AH) Superfund Site (also known as
Twin Cities Army Ammunition Plant or TCAAP) Ramsey County,
Minnesota.
B. Statement of Basis and Purpose
This decision document presents the selected remedial action for
the ground water contamination at operable unit 3 (OU-3) of the
New Brighton/Arden Hills Superfund site (TCAAP) in Ramsey County,
Minnesota, which was chosen in accordance with the requirements
of the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980 (CERCLA), as amended by the Superfund
Amendments and Reauthorization Act of 1986 (SARA) and, to the
extent practicable, the National Oil and Hazardous Substances
Pollution Contingency plan (NCF). This decision document
explains the factual and legal basis for selecting the remedy for
this site. The information supporting this remedial action
decision is contained in the Administrative Record for this site.
The Minnesota Pollution Control Agency (MPCA) and the U.S. Army
(Army) concur with the selected remedy.
C. Assessment of the site
Actual or threatened releases of hazardous substances from this
site, if not addressed by implementing this Record of Decision
(ROD), may present an imminent and substantial endangerment to
public health, welfare, or the environment.
D. Description of the Selected Remedy
The NB/AH Site has been divided into three operable units. The
first operable unit, OU-l, consists of the large north plume of
contaminated groundwater in aquifer units 3 and 4 off-TCAAP. A
remedy for OU-l will be proposed in 1993. The second operable
unit, OU-2, consists of the on-TCAAP soils, sediments, surface
waters, and ground water. A remedy for OU-2 is expected to be
proposed in mid 1994. OU-3, addressed by the remedy selected in
this Record of Decision, consists of the South Plume of off-TCAAP
ground-water contamination. Implementation of the remedies for
the three operable units, as well as continued operation of the
Interim Remedial Action consisting of ground water extraction and
treatment on the TCAAP facility and at the TCAAP facility
boundary, will comprise the final remedy for this site.
The major components of the selected remedy include the
following:
• extraction of ground water at the leading edge of the
South Plume
-------
• treatment of extracted ground water for the removal of
volatile organic compounds (VOCs) by a pressurized
granular activated carbon (GAG) system
• discharge of treated ground water to the potable water
supply of the City of New Brighton
• monitoring of the ground water to verify the
effectiveness of the remedy.
E. Statutory Determinations
The selected remedy is protective of human health and the
environment, complies with Federal and State requirements that
are legally applicable or relevant and appropriate to the
remedial action, and is cost effective. This remedy utilizes
permanent solutions and alternative treatment or resource
recovery technologies, to the maximum extent practicable, and
satisfies the statutory preference for remedies that employ
treatment that reduces toxicity, mobility, or volume as a
principal element. Because this remedy will result in hazardous
substances remaining on-site above health-based levels, a review
will be conducted within five years after commencement of the
remedial action to ensure that the remedy continues to provide
adequate protection of human health and the environment.

II. DECISION SUMMARY
A. site Name, Location, and Description
The New Brighton/Arden Hills (NB/AH) Superfund Site consists of a
25-square mile area located in Ramsey County, Minnesota just
north of the Minneapolis-St. Paul metropolitan area. It includes
the 4-square-mile Twin Cities Army Ammunition Plant (TCAAP) and
portions of seven nearby communities. These communities are New
Brighton, St. Anthony, Arden Hills, Shoreview, Mounds View,
Columbia Heights, and Minneapolis, with the predominant land uses
being mixed residential, commercial and industrial. As presently
defined, the site covers much of the U.S. Geological Survey's New
Brighton, Minnesota 7.5-minute quadrangle (Figure 1).
Within the New Brighton/Arden Hills study area, ground water is
found in both bedrock and glacial deposit aquifers. In general,
there are four aquifer units at the site. The first consists of
the surficial lacustrine deposits that form a shallow, unconfined
aquifer. The second is composed of glacial Twin Cities Till,
which acts as an aquitard, preventing hydraulic communication
between the surface and the underlying major glacial aquifer.
The third is composed of the Hillside and Arsenal Sands and is
the major glacial aquifer in the area. The fourth is the Prairie
du Chien/Jordan bedrock aquifer, which is hydraulically connected
to the overlying Hillside Sand.
The site consists of gently rolling, postglacial terrain with
several hills and surface water bodies, including lakes and
streams, but no extreme relief. The site is located within the
Rice Creek watershed. Rice Creek and its surrounding marshes and
woodlands provide cover for a variety of vegetation and wildlife.
Much of the lowland area adjacent to Rice Creek has lush and
vigorous vegetation creating a wildlife habitat well suited to
small animals.
Rice Creek meanders across the northwestern portion of TCAAP and
leaves TCAAP at the western boundary. Among the many small lakes
located in the Rice Creek Basin, several are located on and near
the TCAAP facility (Figure 2). Surface waters in the Rice Creek
watershed are not currently used for drinking water, but they are
used for recreational purposes.
The TCAAP facility is currently operated by Federal Cartridge
Company (FCC) and used by two manufacturing lessees, Alliant
Techsystems (previously a branch of Honeywell, Inc.) and 3M
Corporation. Approximately 1,500 people are currently employed
at TCAAP. Access to TCAAP is controlled by a 6-foot-high chain-
link fence. The boundary is patrolled by guards.
-------
In general, the off-TCAAP area is suburban in character, is
becoming increasingly urban to the south, and is rural to the
northeast. According to the 1990 census, the population in the
New Brighton quadrangle area is approximately 100,000.
Residential areas virtually surround TCAAP with the heaviest
developments to the west-southwest and east-southeast. Many
schools are located within 2 miles of the TCAAP facility.
The TCAAP facility contains a large number of source areas with
resulting soil, sediment, surface, and ground water
contamination. The source areas associated with on-TCAAP will be
addressed by OU-2.
B. site History and Enforcement Activities
TCAAP has been use to manufacture, store, and test small arms
ammunition and related materials since 1941. Between 1941 and
1981, waste material, including volatile organic compounds
(VOCs), heavy metals, corrosive materials, and explosives, were
used and/or disposed of at the 14 source areas within TCAAP
(Figure 3). In 1981, the Minnesota Pollution Control Agency
(MPCA) and the Minnesota Department of Health (MDH) began ground
water sampling and analysis from wells in the TCAAP area. The
analytical results from these samples indicated that private
drinking water wells and wells at TCAAP were contaminated by
VOCs. As a result, the following actions were taken:
• The City of New Brighton abandoned several municipal wells
and either placed on standby or deepened several others.
• The Village of St. Anthony decommissioned one well and
connected a portion of the village with Roseville water
supplies for an indefinite, but temporary period.
• A number of New Brighton/Arden Hills residents drawing
contaminated drinking water were provided municipal water
through construction of a water main extension.
• Residents of the Arden Manor Trailer Park drawing
contaminated drinking water were provided with new wells
finished in an aquifer with potable water. The wells were
provided by Arden Manor Trailer Park, which was later
reimbursed by the Army.
The MB/AH Site was proposed for inclusion on the National
Priorities List (NFL) in July 1982 and finalized in September
1983, with a Hazard Ranking System (HRS) score of 59 and a
ranking of 43 on the (NFL).' In 1981 the Army began a Phase I
investigation at TCAAP which involved a significant quantity of
monitoring wells and sampling efforts designed to identify the
overall contribution of TCAAP to the NB/AH Site contamination.
In 1983, EPA's Field Investigation Team (FIT) completed a
-------
documentation record and site assessment for the site. The
assessment documented high concentrations of synthetic organic
compounds in ground water at the site. Releases of these
compounds from the site to surface water and direct human contact
with the compounds were also documented. The elevated HRS score
and correspondingly high NPL ranking reflect the following site
conditions: 1) the relatively large number of individuals
exposed to contaminated ground water through their potable water
supplies, and 2) the potentially carcinogenic nature of the
compounds.
The NB/AH site, as currently defined, consists primarily of
portions of several regional aquifers that are contaminated to
differing degrees with volatile organic compounds (VOCs).
Concentrations for several of these compounds exceed current
health based criteria. The affected aquifers supply water to
TCAAP and the municipalities of New Brighton, St. Anthony,
Fridley and Moundsview. On TCAAP itself, contamination of soils,
sediments and surface waters is also of concern.
PROBLEM DEFINITION
Ground water contamination emanating from TCAAP, identified as
the primary source of ground water contamination within the area
of the NB/AH site, has posed a potential health hazard. This
hazard potentially results from direct human contact (dermal
contact,inhalation or ingestion) of ground water with industrial
solvents including trichlorethene (TCE), dichlorethene (DCE),
trichlorethane (TCA) and dichloroethane (DCA). Studies
concerning volatile organic compounds (VOCs) in ground water
within the study area have been undertaken primarily by the Army,
Alliant Techsystems, MPCA, EPA, and private entities. These
studies have largely involved the installation and sampling of
monitoring wells and water quality surveys of production,
municipal, and residential wells. The objectives and results of
the studies are summarized as follows.
PREVIOUS STUDIES
Army reports of investigations and studies at TCAAP in 1983 and
1984 identified major and minor disposal areas on the facility
that were sources of release or threatened release of hazardous
substances (mainly VOCs). In their review of these reports, EPA
and MPCA.noted that additional information was needed to address
the extent and magnitude of contaminated ground water, to fill
data gaps relative to off-site contamination, and to complete an
assessment of the disposal areas identified on TCAAP.
In 1984 and 1985 the Army submitted investigative reports
addressing VOC contamination at Alliant-TCAAP buildings 103 and
-------
6
502 (Sites I and K). The reports indicated that the buildings'
operations were a source of VOC-contaminated ground water
migrating toward Rice Creek from Building 103 and also to the
west or southwest from the Building 502 area. As a result of
these findings, Alliant announced a three-phase off-TCAAP
investigation on July 28, 1984, to supplement work being
conducted by MPCA to identify off-TCAAP sources of release.
In the spring of 1985, EPA initiated an investigation of the
force mains off-TCAAP because a number of documented breaks had
occurred in the line in the study area and because VOCs and other
hazardous wastes and metals had been detected in the sewer
sediments on-TCAAP.
Also in 1985, MPCA released the Phase I Final Report. New
Brighton/Arden Hills. Minnesota Multi-Point Source Remedial
Investigation. The report identified four potential source areas
of VOC release in the study area that had possibly contaminated
the ground water. The source areas included two areas at TCAAP
and two areas adjacent to TCAAP. A second phase of the off-TCAAP
RI, Phase IA, was initiated in July, 1986 and completed in
February, 1991. The purpose of the Phase IA RI was to further
define the nature and extent of ground water contamination in
off-TCAAP. areas.
In 1988, the Army initiated an on-TCAAP RI designed to
characterize the nature and extent of contamination within the
facility boundary, addressing soils, sediments, surface and
ground water. The on-TCAAP RI was completed in April, 1991.
Additionally, in 1991, EPA completed the Human Health Risk
Assessment and Army completed the Environmental Risk Assessment.
The completion of these four documents has led to the development
of feasibility studies for final remedial actions at the NB/AH
site.
INTERIM REMEDIAL ACTIONS
Most of the interim remedial actions (IRAs) taken at TCAAP have
been implemented under the Army Installation Restoration Program
(IRP). These actions have been coordinated with federal and
state regulatory agencies prior to implementation. Alliant
Techsystems entered into an agreement with the Army in 1985 to
investigate and pursue the cleanup of sites at TCAAP associated
with Alliant operations. Industrial operations at TCAAP have
generated most of the contamination currently migrating from the
site. The interim remedial actions being conducted by the Army
and Alliant have concentrated on contaminant source control, with
a focus on individual site cleanups and ground water (aquifer)
remediation. Actions that have already been taken can be divided
into the categories of: a) alternate water supplies, b)
-------
unilateral actions by the Army, c) actions with EPA and state
concurrence and d) other actions initiated by EPA and/or Army.
a) Alternate Water supplies
In addition to the previously mentioned alternate water supplies
that were provided shortly after the discovery of contamination
at the site, the following systems have been completed:
• A temporary, followed by a permanent, GAG treatment system
constructed for the City of New Brighton by the Army as part
of a litigation settlement agreement. The permanent system,
completed in June 1990, presently treats water from New
Brighton Wells 3, 4, 5 and 6 and has a capacity of 3200
gallons per minute (gpm).
• A temporary, followed by a permanent, GAG system constructed
for the Village of St. Anthony by EPA/MPCA. The permanent
system is a remedial action pursuant to a Record of Decision
(ROD) signed in September 1986. The system, completed in
April 1991, treats water from St. Anthony Wells 3, 4 and 5
and has a capacity of 2400 gpm.
b) Unilateral Actions by the Army
Unilateral removal actions have been taken by the U.S. Army using
its own delegated removal authorities under CERCLA Section 104.
These actions have, included:
• In-situ soil vapor extraction (ISV) systems for the
remediation of contaminated soils at Sites D and G on-TCAAP.
The ISV systems were implemented in 1986 and, since then,
have removed over 114 tons of VOCs from site soils.
• A ground water pump-and-treat system at Site A, where the
surficial aquifer is contaminated with VOCs. The system,
installed by the Army in 1988, utilizes liquid-phase
activated carbon to treat extracted groundwater, which is
then surface-discharged.
• Ground water pump-and-treat systems installed in 1988 at
Sites I and K, Alliant operations buildings. Groundwater
underneath the buildings is contaminated with VOCs with the
likely source identified as leaks from floor drains and
sewer lines. The extracted ground water is treated by air
stripping. The treated ground water from Site K is
discharged to a sewer under a National Pollutant Discharge
Elimination System (NPDES) permit issued by the state. The
treated ground water from Site I is discharged to the TCAAP
Ground Water Recovery System (TGRS). The TGRS is more fully
described in the next section.
-------
c) Actions with EPA and state Concurrence
• In 1987 the Army implemented the Boundary Groundwater
Recovery System (BGRS), for which EPA signed a Record of
Decision (ROD) in September 1987. This system initially
consisted of a series of six groundwater extraction wells
located along the southwest boundary of TCAAP and designed
to prevent any further migration of contaminated ground
water off of TCAAP. After a period of performance
monitoring, the system was expanded in 1989 to twelve wells.
Eight of the BGRS wells draw water from the Hillside Sand
aquifer with the other four drawing from the Prairie du
Chien.
The BGRS operates at an extraction rate of approximately
2100 gpm. Extracted water is pumped to an air stripping
facility for the removal of VOCs. From there the treated
water is pumped to the Arsenal Sand and Gravel Pit in the
north-central portion of TCAAP, where it is discharged and
allowed to infiltrate back into the ground. Over 5 billion
gallons of water have been treated and 45 tons of VOCs
removed by this system.
• In addition to the implementation of the BGRS, the Army
subsequently installed five source control (SC) wells
downgradient of Sites D, G and I. The BGRS and the SC wells
together comprise the TCAAP groundwater recovery system
(TGRS). The BGRS and TGRS are designed to provide regional
ground water remediation at TCAAP and prevent additional
contamination from migrating beyond the facility boundaries.
d) Other Actions Initiated by EPA and/or Army
• Site J, the sanitary sewer system at "PCAAP, has been
investigated in several studies. In 1983, integrity testing
was conducted on part of the upper plant sewer and on the
18-inch and 24-inch force mains. During 1984, approximately
50 percent of the sanitary sewer system (over 42,000 linear
feet) was inspected, cleaned, and tested. By July 1986,
cleaning of all sewer lines was completed.
• Between 1984 and 1986, Alliant Techsystems removed
contaminated sludge from the sewers leading away from
Building 502, containerized the sludge in drums and stored
it in a building called the Retrievable Monitored
Containment Structure (RMCS). In addition, in 1985, Alliant
excavated PCB-contaminated soils around Building 502 and
placed them in the RMCS.
• 1400 cubic yards of PCB-contaminated soil at Site D were
thermally treated in 1989. EPA prepared the ROD and the
risk assessment report for this action.
-------
• The Army completed a two-phase water management study to
evaluate feasible alternatives for the disposal of treated
ground water anticipated from future remedial measures.
CERCLA ENFORCEMENT ACTIVITIES
Pursuant to Section 120 of the Superfund Amendments and
Reauthorization Act of 1986 (SARA), the Army entered into a
Federal Facility Agreement (FFA) with EPA and the State of
Minnesota. The TCAAP FFA, which became effective on December 31,
1987, was the first to be negotiated between EPA and any federal
agency since the enactment of SARA. The general purposes of the
FFA are to:
1) Ensure that the environmental impacts associated with past
and present activities at TCAAP are thoroughly investigated
and that appropriate remedial actions are taken to protect
the public health, welfare and the environment.
2) Establish a procedural framework and schedule for
developing, implementing, and monitoring appropriate
response actions in accordance with CERCLA/SARA, the
National Oil and Hazardous Substances Pollution Contingency
Plan (NCP), Superfund guidance and policy, The Resource
Conservation and Recovery Act (RCRA), and RCRA guidance and
policy.
.("•0
3) Ensure cooperation, information exchange and participation
of the parties in such actions.
The specific purposes of the agreement are to:
1) Identify interim remedial action alternatives appropriate
for preventing further migration of contaminated ground
water prior^tp the implementation of final remedial actions
for the site,;'
2) Establish requirements for conducting the on-TCAAP RI to
determine fully the nature and extent of the threat to the
public health, welfare, or the environment caused by the
release and threatened release of hazardous substances,
pollutants, or contaminants at TCAAP.
3) Establish requirements for conducting an FS for the site to
identify, evaluate, and select alternatives for the
appropriate remedial action(s) to prevent, mitigate, or
abate the release or threatened release of hazardous
substances, pollutants, or contaminants at the site in
accordance with CERCLA and SARA.
4) Identify the nature, objective, and schedule of response
actions to be taken at the site. Response actions at the
-------
10
site shall attain that degree of cleanup of hazardous
substances, pollutants, or contaminants mandated by CERCLA
and SARA.
5) Implement the selected interim and final remedial action(s).
6) Assure compliance with federal and state hazardous waste
laws and regulations for matters covered by the agreement.
c. Highlights of Community Participation
The community near TCAAF has been involved in site activities
since the environmental problems related to the TCAAP facility
were identified. Numerous fact sheets have been sent and public
meetings have been held to keep the community apprised of the
various remedial activities at the site.
For the remedy selection for OU-3, the public participation
requirements of CERCLA sections 113 (k)(a)(B)(i-v) and 117 were
met through the issuance of a fact sheet and Proposed Plan,
notification of the availability of the Proposed Plan by
newspaper, and the holding of a public meeting on August 18,
1992. The public comment period for the Proposed Plan began on
July 22, 1992, and ended on August 21, 1992.
O. Scope and Role of operable Unit Within site strategy
OU-3 is one of three operable units for this site. OU-3 will
address the off-TCAAP ground water contamination occurring in the
South Plume in aquifer Unit 3 and Unit 4. OU-1 will address the
off-TCAAP ground water contamination occurring in the North
Plume. OU-2 will address the on-TCAAP source areas including
contaminated soils, sediments, surface water and ground water.
These three operable units, combined with the currently operating
TGRS, will comprise the final remedy for this site. OU-3
provides for the containment and eventual restoration of the
South Plume of contaminated ground water located off-TCAAP in
aquifer Unit 3 and Unit 4.
The division of the site into three operable units for purposes
of the final remedial action is based upon the following
considerations:
1) The on-TCAAP RI recommended that additional site
characterization work be performed within the boundaries of
TCAAP for soils, surface waters, sediments and groundwater.
This additional work must be completed before remedial
alternatives can be proposed for these media. The operation
of the BGRS interim remedial action, designed to prevent the
further migration of contaminated groundwater past the TCAAP
boundary, has allowed off-TCAAP groundwater contamination to
be considered separately from on-TCAAP sources and

contaminated media. Therefore, delaying a response to off-
TCAAP groundwater contamination until the completion of the
additional on-TCAAP work is not warranted.
2) Based upon the results of the off-TCAAP RI, proposed
remedial alternatives for the large off-TCAAP North Plume of
contaminated groundwater, OU-l, will require a more involved
analysis than is necessary for the smaller South Plume, OU-
3. This analysis will include detailed groundwater modeling
and an evaluation of the effects of the alternate water
supplies provided to the City of New Brighton and the
Village of St. Anthony. The separation of the South Plume
into a separate operable unit prevents the migration of the
South Plume into uncontaminated portions of the affected
aquifer in a more timely fashion.
In sum, EPA has determined that a phased approach is appropriate,
given the size and complexity of the site , and will expedite the
completion of total site cleanup. EPA has also concluded that
OU-3 will not be inconsistent with nor preclude implementation of
other components of the final site remedy.
E. Summary of site characteristics
within the New Brighton/Arden Hills study area, ground water is
found in both bedrock and glacial deposit aquifers. On top of
the irregular bedrock surface, a series of unconsolidated glacial
sediments has been deposited. Several of these units are water
bearing and have been affected by the spread of contaminants from
TCAAP.
The Prairie du Chien/Jordan Sandstone aquifer is the principal
aquifer in the Twin Cities Basin. This aquifer is referred to as
Unit 4. Permeability in the Prairie du Chien/Jordan Sandstone
aquifer is controlled by the extent of fractures and joints in
the Prairie du Chien unit and the porosity of the Jordan
Sandstone unit. Ground water flow through this aquifer is
generally in a west-southwest to south-southwest direction off-
TCAAP toward the Mississippi River. Recharge to the Prairie du
Chien/Jordan Sandstone aquifer occurs by infiltration through the
overlying glacial units. Aquifer performance tests involving the
Prairie du Chien/Jordan Sandstone aquifer, as well as subsequent
modeling, suggest that a semiconfining layer may exist between
the Jordan Sandstone and Prairie du Chien units.
The Hillside Sand and the Arsenal Sand are referred to as Unit 3.
Within the New Brighton quadrangle, the Hillside/Arsenal Sand
outcrops in four areas: the Arsenal Kame within TCAAP; the
southwestern corner of the quadrangle within Minneapolis; two
small areas in Columbia Heights in the vicinity of Silver Lake;
and along the southern edge of Snail Lake. Except for the
exposure in Minneapolis, the Hillside/Arsenal Sand directly
-------
12
overlies the Prairie du Chien/Jordan Sandstone aquifer; the other
three surface exposures provide direct recharge to both units.
The ground water in the Unit 3 flows predominantly southwest.
The Twin Cities Till overlies the Hillside Sand in much of the
area and is referred to as Unit 2. The Twin Cities Till acts as
a confining layer, preventing direct hydraulic communication
between the overlying Lacustrine Deposits and the Hillside Sand
below.
The Lacustrine Deposits (Unit 1) are predominantly fine to medium
sands with interbedded silt layers and occasional minor peat and
clay layers. These units form the shallow surface aquifer
between and to the north of the Hilltop and Arden Hills moraines.
Private wells installed in Unit 1 exist to the north of TCAAP.
Ground water in this unit is perched and discontinuous. Any
ground water flow is localized and toward the closest small lake.
Ground water in Unit 3 and Unit 4 aquifers is considered Class II
in accordance with, "EPA Guidelines for Ground water
Classifications." Class II groundwater is groundwater that may
potentially be used as a potable water supply. Unit 3 and 4
ground water is of potable quality and is currently used as a
drinking water supply.
Ground water in aquifer Units 1, 3, and 4 has been contaminated
by one or more of the 14 source areas identified on the TCAAP
facility. Off-TCAAP, VOCs within the South Plume migrate
horizontally and downward vertically in response to corresponding
hydraulic gradients. The South Plume migrates in a southwesterly
direction off TCAAP in both the Hillside and Prairie du Chien
aquifers. The north and South Plumes diverge immediately off-
TCAAP with the South Plume moving in a more southerly direction
(Figure 4).
The South Plume extends approximately 10,000 feet beyond TCAAP.
The down gradient limit of the South Plume is evidenced by low
level of VOCs at wells in the Unit 4 aquifer. Unit 3 no longer
exists at the leading edge of the plume, so any contamination
present will be found in the Unit 4 aquifer.
In the Operable Unit 3 Feasibility Study, six VOCs have been
identified at concentrations above 1 /tg/1 in the South Plume, as
follows, in descending order based on concentration:
Trichloroethene
Cis-i,2-Dichloroethene
1,l-Dichloroethene
1,1-Dichloroethane
1,1,1-Trichloroethane
1,1,2-Trichloroethane
-------
13
Of these six VOCs, trichloroethene is of most concern because it
is present in the highest concentration and because it is
carcinogenic. Concentrations of trichloroethene in Unit 3 range
from < l M9/1 "to 3,800 pg/1. Trichloroethene concentrations in
Unit 4 range from < 2.6 ng/1 to 420 pg/1. Concentrations
decrease away from the center of the plume and with increasing
distance from the site. Figure 5 shows concentrations for
trichloroethene in Unit 3. Figure 6 shows concentrations for
trichloroethene in Unit 4.
F. Summary of OU-3 Risks
In 1990 EPA conducted a Human Health Risk Assessment for the
site. The Risk Assessment evaluated both on-TCAAP and off-TCAAP
areas affected by contamination under current and future use for
both the probable and reasonable maximum exposure (RME)
scenarios. The portions of the Risk Assessment regarding off-
TCAAP ground water risks are summarized in this section of the
ROD. It should be noted that both the South Plume and North
Plume for Unit 3 and Unit 4 were included in the off-TCAAP ground
water risk assessment. The V, w, X, Y, and Z areas of Unit 3 and
Unit 4, as shown in Figures 5 and 6, are based on general
concentration levels of trichloroethene. These general
concentration areas of Unit 3 and Unit 4 occur in both the South
and North Plumes. The arithmetic averages and upper-bound 95%
confidence levels for the contaminants of concern were calculated
based on contaminant concentrations in the South and North
Plumes. Human health risks were evaluated using a four step
process: 1) contaminant identification, 2) exposure assessment,
3) toxicity assessment, and 4) risk characterization. Each of
these steps is summarized below.
1) Contaminant identification
The media of concern for OU-3 is ground water in the South Plume
of aquifer Unit 3 and Unit 4. Table 1 specifies the contaminants
of concern for the South Plume according to the Risk Assessment
Exposure Areas labeled V, W, X, Y, and Z. The contaminant
concentrations used in quantifying risks from ground water
exposure are presented in Table 2. The probable exposure
scenario used the arithmetic average for individual contaminant
concentrations. The upper-bound 95% confidence limit on the
arithmetic average for individual contaminants was the
concentration used to calculate the reasonable maximum exposure
(RME). The maximum concentration measured for a given exposure
point was used to represent RME conditions when the upper-bound
95% confidence limit on the arithmetic average exceeded the
maximum concentration.
-------
14
2) Exposure Assessment
Both the current and future potential risk from exposure to off-
TCAAP contamination was evaluated. The current and future uses
were the same for the ground water pathway. Currently, most
residents living off-TCAAP receive their potable water from
municipal water supply wells. The water from these wells is
either contaminant-free when drawn from the ground or, in the
case of the municipal water supply wells of New Brighton and St.
Anthony, runs through granular activated carbon (GAG) treatment
systems that reduce contamination to required levels before being
distributed to the public. The only way that residents would be
exposed to contaminated ground water would be if the current GAC
treatment systems fail. Such failures are not expected because
of the redundancy built into the system, with the carbon units
operating in series.
Officials from off-TCAAP municipalities have acknowledged that a
small number of unidentified private water supply wells may exist
off-TCAAP to the southwest. EPA, MPCA and Army have solicited
information regarding private well use in the area. Army has
notified local residents through various media in an effort to
identify private wells impacted by the contaminated plumes off-
TCAAP and none have, at this time, been identified. Currently,
Army is conducting an additional well search in the area. This
effort is being coordinated with the State of Minnesota and EPA.
The present number of private wells within the plume extending
southwest from TCAAP cannot be determined at this time.
In the future, ground water in Unit 3 and Unit 4 will continue to
be used as potable water for municipal supplies and may be used
by private well users near the site. The rate of usage will
likely increase as the area grows and develops further.
Exposure to chemicals in ground water may occur via three routes:
(1) ingestion, (2) inhalation of volatiles during showering, and
(3). dermal absorption during bathing. If any of the water users
are commercial/industrial operations, then exposure would be
assumed to occur primarily via ingestion unless specific
instances of bathing could be documented.
The parameter values used in quantification of exposure for the
probable and RME scenarios are listed in Table 3. The exposure
doses or chronic daily intakes per pathway for the probable and
RME scenarios are presented in Table 4.
3) Toxicitv Assessment
A toxicity assessment is conducted to provide qualitative and
quantitative information regarding the potential for particular
contaminants to cause adverse effects in exposed individuals.
Toxicity values, such as slope factors and reference doses, are
-------
15
derived from the quantitative assessment and used together with
exposure assessment values to characterize risk.
Cancer potency or slope factors (SFs) have been developed by
EPA's Carcinogenic Assessment Group for estimating excess
lifetime cancer risks associated with exposure to potentially
carcinogenic chemicals. SFs, which are expressed in units of
(mg/kg-day)'1, are multiplied by the estimated intake of a
potential carcinogen, in mg/kg-day, to provide an upper-bound
estimate of the excess lifetime cancer risk associated with
exposure at that intake level. The term "upper bound" reflects
the conservative estimate of the risks calculated from the SF.
Use of this approach makes underestimation of the actual cancer
risk highly unlikely. Slope factors are derived from the results
of human epidemiological studies or chronic animal bioassays to
which animal-to-human extrapolation and uncertainty factors have
been applied.
Reference doses (RfDs) have been developed by EPA for evaluating
the potential for adverse health effects from exposure to
chemicals exhibiting noncarcinogenic effects. RfDs, which are
expressed in units of mg/kg-day, are estimates of lifetime daily
exposure levels for humans, including sensitive individuals,
above which there may be an appreciable risk of adverse health
effects. Estimated intakes of chemicals from environmental media
(e.g., the amount of a chemical ingested from contaminated
drinking water) can be compared to the RfD. RfDs are derived
from human epidemiological studies or animal studies to which
uncertainty factors have been applied (e.g., to account for the
use of animal data to predict effects on humans). These
uncertainty factors help ensure that the RfDs will not
. underestimate the potential for adverse noncarcinogenic effects
to occur.
Table 5 lists the oral and inhalation reference doses for the
contaminants of concern. Table 6 lists the oral slope factors
for the contaminants of concern. Table 7 lists the inhalation
slope factors for the contaminants of concern.
4) Risk Characterization
The quantitative risk characterization combines the results of
the exposure assessment and toxicity assessment to characterize
the carcinogenic and noncarcinogenic risks posed by contaminants
at the site.
The determination of carcinogenic risk is based upon calculating
how much of an increased risk a chemical poses over the average
or "background" level. For the general population, the
background risk of cancer is about one chance in three, or 33
percent, of developing some form of cancer in one's lifetime.
-------
16
EPA uses a range of increased cancer risk of betveen one in tea
thousand to one in one million (l x 10*4 to 1 x 1CT6) as the level
at which it requires that action be taken to reduce risk.
The determination of noncarcinogenic risk is based upon the
calculation of a term called the Hazard Index. If the Hazard
index for a risk pathway is less than one, noncarcinogenic risk
is not expected at the site. A Hazard Index greater than one
represents a potential for the occurrence of noncarcinogenic
health risks.
For off-TCAAP' ground water, there is a greater than 1 x ICT*
carcinogenic risk associated with 1,1-dichloroethene and
trichloroethene in portions of both Unit 3 and Unit 4 aquifers.
Noncarcinogenic hazard indices were less than one in nearly all
cases. There-were some exceedances of a hazard index of one for
a few individual chemicals. These exceedances were slight and do
not cause a noncarcinogenic risk for Unit 3 or Unit 4 ground
water in the areas encompassed by this operable unit.
Table 8 presents the non-carcinogenic and carcinogenic risks for
the probable and RME scenarios. Unit 3 and Unit 4 were divided
into areas based on the concentration of trichloroethene (see
Figures 5 and 6). Both the chronic and acute hazard indices were
evaluated for noncarcinogenic risks.
Table 9 summarizes the areas of uncertainty and their effects on
the risk estimates.
An ecological assessment was conducted for the Site by the Army.
This assessment will be augmented by additional work during the
Feasibility Study for QU-2. OU-3 is not ecologically impacted
because Unit 3 and Unit 4 ground water aquifers are deep and do
not affect surface waters in the area of contamination.
Actual or threatened releases of hazardous substances from this
site, if not addressed by implementing the response action
selected in this ROD, may present an imminent and substantial
endangerment to public health, welfare, or the environment.
6. Description of Alternatives
The OU-3 Feasibility Study examined appropriate remedial
technologies (Table 10) and combined these technologies into
various remedial alternatives. The remedial alternatives were
screened and evaluated, resulting in the retention of three
alternatives plus the no-action alternative, for detailed
analysis. A description of the alternatives analyzed in detail
is presented below:
-------
17
Alternative 1: No Action With Monitoring
Evaluation of the No Action Alternative is required by the NCP.
The No Action Alternative serves as a baseline alternative for
comparison to the "action" alternatives. Under this alternative,
no additional remedial action would be undertaken for the South
Plume. Access to contaminated ground water could be somewhat
controlled by enforcing well drilling permit regulations to help
prevent the potential exposure to persons consuming water from
private wells in the area. Ground water monitoring would
continue under the existing Federal Facilities Agreement. The no
action alternative provides no additional protection of human
health or the environment. The South Plume would continue to
migrate beyond the current monitoring well network and impact
currently "clean" portions of the deep aquifers (Units 3 and 4).
Capital Cost: $0
Annual O&M: $50,000
Present Worth: $471,000
Alternative 2: Ground water Extraction/ Treatment at TCAAP Air
Stripping Facility/ Discharge to Arsenal sand and Gravel Pit
Alternative 2 proposes installation of a ground water extraction
well located in aquifer Unit 4 at the leading edge of the South
Plume. Water would need to be pumped from Unit 4 at a rate of
1,000 gallons per minute to contain the South Plume. Near the
leading edge of the South Plume Unit 3 merges with Unit 4.
Therefore pumping of Unit 3 would not be necessary. At present
one extraction well is proposed. However, based on the results
of pump tests, additional wells would be added if they were
needed to contain the South Plume. Monitoring wells would be
added to the Unit 4 network to verify hydraulic capture.
The extracted ground water would be piped to TCAAP and undergo
treatment by air stripping at the existing TCAAP treatment
system. The existing system would be expanded to accommodate the
additional flow, with the treated water being discharged to the
Arsenal Sand and Gravel Pit. The Arsenal Sand and Gravel Pit is
currently used for discharge of treated water from the TGRS. The
major disadvantage of this discharge option is the potential
limitation to the amount of water that can be recharged to the
gravel pit without affecting VOC capture by the BGRS.
The area of attainment for this alternative is the areal and
vertical extent of Unit 3 and Unit 4 now encompassed by the South
Plume. The South Plume extends approximately 10,000 feet beyond
the TCAAP boundary and is approximately 2,000 feet wide. The
point of compliance for monitoring would be at the leading edge
of the South Plume. The final performance monitoring system
would be established during the remedial design/remedial action.
-------
18
There are two major Applicable or Relevant and Appropriate
Requirements (ARARs) for Alternative 2. One relates to ground
water cleanup levels, and the other relates to operation of the
treatment system. The contaminated ground water in the South
Plume must be extracted and treated until the concentration of
the six VOCs reaches the cleanup levels specified in this Record
of Decision. As Class II ground water aquifers, Units 3 and 4
should be restored to drinking water quality. The estimated
aquifer restoration timeframe is 30-to-50 years. The Safe
Drinking Water Act (SDWA) MCLs and non-zero MCLGs are considered
relevant and appropriate based on Section 300. 400 (g) of the NCP.
The State of Minnesota Recommended Allowable Limits (RALs) are to
be considered (TBCs) as cleanup standards also. The following
table lists MCLGs, MCLs and RALs for the contaminants of concern.
MCLG/MCL/RAL TABLE
Compound MCLG r,ucr/l) MCL facr/1) RAL
1,1- Dichloroethane - 70
1,1- Dichloroethene 7 76
Cis-1,2- Dichloroethene 70 70 70
1,1,1- Trichloroethane 200 200 600
1,1,2- Trichloroethane 3* 5* 3
Trichlproethene Zero 5 30
'Proposed MCL/MCLG
Because the affected aquifer may potentially be used for both
public and private drinking water supplies, the lowest
concentration value among the MCL, non-zero MCLG or RAL would be
followed. If a particular contaminant does not have an MCL or
non-zero MCLG, such as 1, 1-dichloroethane, the RAL would be
followed.
If contaminants of concern reach static concentrations over a
period of time, the extraction system would be evaluated to
determine if alternate pumping strategies would enhance
contaminant recovery. Ground water monitoring would be required
until restoration of the aquifer is achieved and the extraction
system is shut down.
The RCRA requirements of 40 CFR 264 Subpart AA, limiting total
organic emissions from air strippers would be relevant and
appropriate to Alternative 2. Alternative 2 would comply with
this ARAR.
The water well drilling regulations established by the State of
Minnesota is an institutional control that would be used to help
prevent the installation of private wells in the South Plume
before cleanup standards are achieved. These regulations also
protect aquifers from the spread of contamination by requiring
-------
19
specific construction procedures and materials, maintenance
standards and abandonment procedures from all wells, including
monitoring and pumping wells.
Alternative 2 would take approximately 4 months to implement.
Capital Cost: $2,764,000
Annual o&M: $ 258,000
Present Worth: $5,196,000
Alternative 3: Ground water Extraction, Treatment with Granular
Activated carbon (GAG), Discharge to Mew Brighton Municipal Water
supply
Alternative 3 would use the same extraction system proposed for
Alternative 2. The extracted ground water would be conveyed to a
new GAC treatment system (Figure 7) and inorganic treatment
facility to be constructed at the New Brighton Public Works
garage area. A pilot study would be conducted to determine the
most efficient and cost effective precipitation/filtration
combination to be used for treatment of inorganics. Treated
ground water would be discharged to the City of New Brighton
municipal water supply system, through a newly constructed force
main. New Brighton would use the treated water for its potable
water supply.
The area of attainment and point of compliance described in
Alternative 2 also applies to Alternative 3. In addition to the
ARARs and institutional controls outlined in Alternative 2,
Alternative 3 would have to comply with RCRA 40 CFR Part 268
Subpart D for the disposal of spent carbon. The tanks used for
treatment of the ground water would need to comply with the
substantive requirements for tanks set forth in 40 CFR Part 264
Subpart J.
Iron and manganese, the two predominant inorganics, would be
removed to comply with SDWA secondary Drinking Water Standards.
The treated ground water must meet the cleanup standards
specified in this ROD, which are MCLs and/or RALs, for the six
VOCs of concern. The time to implement Alternative 3 would be
approximately 6-9 months.
Capital Cost: $2,249,000
Annual O&M: $ 276,000
Present Worth: $4,851,000
Alternative 4: Extraction of Ground water, Treatment with GAC,
Discharge to Mississippi River
This alternative would consist of the same extraction system
described in Alternative 2. The treatment system would be the
same as for Alternative 3, except that it would not include
-------
20
inorganics removal. Treated water would be discharged via a
pipeline from the New Brighton Public Works garage area to the
Mississippi River. This pipeline would be constructed along the
1-694 right-of-way. This option would require a variance from
the U.S. Department of Transportation regulations that regulate
utilities along interstate highway right-of-ways.
The area of attainment and point of compliance for Alternative 4
is the sane as that described for Alternative 2. Major ARARs for
Alternative 4 include MCLs and RALs for ground water cleanup,
RCRA regulations regarding tanks used in the treatment process
and disposal of spent carbon, and National Pollution Discharge
Elimination System (NPDES) effluent limitations established by
the Clean Water Act 40 CFR Parts 104-140, 401-469. The
institutional controls described in Alternative 2 also apply to
Alternative 4.
The implementation time for Alternative 4 would be approximately
6-12 months.
Capital Cost: $6,521,000
Annual O&M: $ 366,000
Present Worth: $9,971,000
H. Summary of the Comparative Analysis of Alternatives
The NCP requires that the alternatives be evaluated on the basis
of the nine evaluation criteria listed below. This section
summarizes how the alternatives retained for detailed analysis
compare to one another when measured against the nine criteria.
EPA's Nine Evaluation Criteria for addressing hazardous waste
sites are:
1) Overall Protection of Human Health and the Environment
The assessment against this criterion describes how the
alternative, as a whole, achieves and maintains protection
of human health and the environment.
2) Compliance with Applicable or Relevant and Appropriate
Requirements (ARAR1
The assessment against this criterion describes how the
alternative complies with existing federal, state and
municipal laws, regulations, and other established standards
or, if a waiver is required, how it is justified. The
assessment also addresses other information from advisories,
criteria, and guidance that are to be considered.
-------
21
3) Lonq-Term Effectiveness and Permanence
The assessment of alternatives against this criterion
evaluates the long-term effectiveness of alternatives in
maintaining protection of human health and the environment
after response objectives have been met.
4) Reduction of Toxicitv, Mobility, and Volume Through
Treatment
The assessment against this criterion evaluates the
anticipated performance of the specific treatment
technologies employed by an alternative.
5) Short-Term Effectiveness
The assessment against this criterion examines the
effectiveness of the alternative in protecting human health
and the environment during the construction and
implementation of a remedy until response objectives have
been met.
6) Implementability
This assessment evaluates the technical and administrative
feasibility of alternatives and the availability of required
goods and services.
7) Cost
This assessment evaluates the capital and operation and
maintenance (O&M) costs of each alternative.
8) State Acceptance
This assessment reflects the state's apparent preferences
among or concerns about alternatives.
9) Community Acceptance
This assessment reflects the community's apparent
preferences or concerns about alternatives.
Comparative Evaluation of Alternatives
A comparative evaluation of the four alternatives for each of the
nine criteria is presented below and summarized in Table 11.
-------
22
Threshold Criteria
1. Overall Protection of Human Health and the Environment
The no action alterative provides no additional protection
of human health or the environment such that the site would
continue to present an imminent and substantial endangerment
to human health and the environment. The remaining three
alternatives all provide the same degree of overall
protection of human health and the environment in limiting
further migration of contaminants from the South Plume.
However, the discharge of treated water to the Arsenal Sand
and Gravel Pit could potentially compromise the BGRS by
causing an increased flow of contaminated ground water
between the BGRS wells. Therefore, Alternative 2 would not
be as protective as Alternatives 3 and 4.
Institutional controls, such as water well drilling
regulations will help to prevent consumption of contaminated
ground water in the South Plume until the cleanup standards
are met. The extraction of ground water will prevent
further migration of contaminants, protecting ground water
users downgradient of the South Plume.
2. Compliance with ARARs
The no action alternative allows contamination present in
the ground water to remain and migrate. The remaining
alternatives remove contamination so that the treated ground
water meets all ARARs.
The extraction and treatment portions of Alternatives 2, 3,
and 4 would meet the requirements of the Safe Drinking Water
Act (40 CFR Parts 141-149) for MCLs, the Minnesota RAL for
1,l-Dichloroethane and 1,1-Dichloroethene, and the
requirements of the Resource Conservation and Recovery Act
(RCRA) (40 CFR Part 268 Subpart D) for the disposal of spent
carbon. In addition, the tanks used for the treatment of
the ground water would comply with the substantive
requirements for tanks set forth in 40 CFR Part 264 Subpart
J. Alternative 2 would also comply with RCRA requirements
limiting total organic emissions from air strippers (40 CFR
264 Subpart AA). Finally, Alternative 4 would comply with
the effluent limitations of NPDES which was established
under the Clean Water Act (40 CFR Parts 104-140, 401-469).
-------
23
Primary Balancing Criteria
3. Lona-Term Effectiveness
The no action alternative, which includes continued ground
water monitoring, provides no long-term effectiveness.
Alternative 2, in the absence of supplemental water
discharge options, will eventually have a negative, long-
term impact on contaminant capture because additional ground
water will re-enter in the Arsenal Sand and Gravel Pit and
likely effect contaminant capture at the BGRS. Alternatives
3 and 4 will remain effective on a long-term basis.
Alternative 3 will provide a long-term source of treated
water for use by the City of New Brighton. Because it
provides the best use of the local ground water resource,
Alternative 3 is considered to be better than Alternative 4.
The uncertainty associated with the extraction system's
ability to achieve cleanup standards in the long-term
affects Alternative 2, 3, and 4 equally.
4. Reduction of Toxicitv. Mobility, and Volume (TM\n
The no action alterative provides no reduction of TMV.
Alternatives 2, 3, and 4 reduce toxicity by treating vocs,
and reduce the volume of contamination by removing it from
the ground water. Alternatives 2, 3, and 4 are, therefore,
equally effective for reduction of TMV.
5. Short-Term Effectiveness
The no action alternative, which includes continued
monitoring, provides no short-term effectiveness.
Alternatives 2 and 4, in their requirement for the
construction of pipeline along rights-of-way to the Arsenal
" Sand and Gravel Pit and to the Mississippi River,
respectively, would take somewhat longer to construct and
would have greater short-term impacts than Alternative 3.
Alternative 3, in which well(s) and conveyances are all
contained within the same area of New Brighton, has the
fewest short-term environmental impacts. Alternatives 2, 3,
and 4 each require the'same amount of time to restore ground
water to cleanup standards, and use institutional controls
to help prevent use of contaminated ground water until
cleanup standards are reached. Alternatives 2, 3, and 4 are
all considered acceptable when evaluated against this
criterion.
6. Implementability
Alternative 1, the No Action alternative, does not require
implementation. Alternative 2 utilizes conventional
extraction and treatment technologies; however, the
-------
24
forcemain will require significant access arrangements and
cooperation from various government units and private
parties. Thus, installation of the forcemain could be
delayed. Alternative 3 is fully implementable using
conventional construction technologies. New Brighton is
willing to accept the treated water and to provide easements
for a forcemain and the treatment plant construction.
Alternative 4 is implementable using conventional
construction technologies but would require forcemain
construction through highly developed areas and an exemption
from Federal Transportation Department regulations, either
of which will require substantial lead times. Alternative
3, therefore, is the most: implementable alternative.
7. Cost
The capital, O&M, and present worth costs (based on a 30
year period and 10% discount rate) for the four alternatives
are summarized below:
Annual
Capital Cost O&M Cost Present Worth
Alternative 1 $0 $50,000 $ 471,000
Alternative 2 $2,764,000 $258,000 $5,196,000
Alternative 3 $2,249,000 $276,000 $4,851,000
Alternative 4 $6,521,000 $366,000 $9,971,000
Modifying Criteria
8. State Acceptance
Based on the State's objective of obtaining an expedited
remediation, the No Action alternative is not acceptable.
Alternative 2 consists of expanding the existing, approved
system. The State has voiced concerns in two areas: (1) the
long-term impact of additional ground water recharge to the
Arsenal Sand and Gravel Pit on VOC capture at the BGRS, and
(2) the fact that recharge in the Arsenal Sand and Gravel
Pit may not provide the most beneficial use of the ground
water resource. The State accepts Alternative 3 because
this alternative would prevent further migration of the
South Plume, and it is the most beneficial use of treated
ground water. Alternative 4 is not acceptable to the State
because it is not a beneficial use of the ground water
resource.
9. Community Acceptance
Community acceptance of Alternative 3 is anticipated based
upon the desire of the City of New Brighton for additional
-------
25
potable water, which Alternative 3 would provide, and the
general desire of citizens living in the area that effective
ground water remediation proceed as soon as possible. Based
upon public comments received during the public comment
period and during the public meeting for the proposed plan
and feasibility study for the site, the community prefers
Alternative 3.
I. The selected Remedy
The selected remedy for the OU-3 ground water cleanup is
Alternative 3. Based upon hydrogeologic and chemical data
collected across the study area, EPA and MPCA estimate that one
or more extraction wells will be needed to meet the objectives of
containing and remediating the South Plume ground water
contamination off-TCAAP. The extraction well(s) will be drilled
into the deep aquifer (Unit 4) to capture South Plume
contamination. At the proposed ground water extraction well
location, Unit 3 merges with Unit 4. Preliminary estimates
indicate that pumping ground water at a rate of approximately
1,000 gallons per minute will effectively contain the plume.
Based on additional work to be performed, EPA and MPCA will
determine if the pumping rate is sufficient to contain the south
Plume. If the pumping rate is found not to contain the South
Plume, the system will be expanded or modified to meet the
cleanup objectives.

A forcemain will, be constructed from the location of the
extraction well(s) to the treatment system. The forcemain will
carry treated water from the system to the New Brighton water
supply main. The length of the forcemain will depend on the
distance between the extraction well(s), which have not been
installed, and the treatment plant. The length of the forcemain
between the treatment plant and the water main will be
approximately 6Q£J,feet. This forcemain will be located on city
property. The treatment system will utilize precipitation and
filtration for inorganic solids removal and a pressurized GAC
system for VOC removal. The removal of inorganic solids,
primarily iron and manganese, is needed to make the water
acceptable to the City of New Brighton. Iron and manganese are
naturally found in water, and they must be removed to prevent the
fouling of pipe and well screen openings, to prevent yellow
staining of clothing, and to remove taste and odor problems.
Treated ground water will be discharged to the 12-inch New
Brighton water main, which runs approximately 600 feet west of
the proposed treatment plant location (Figure 8).

Alternative 3 will achieve substantial risk reduction by
effectively containing the contaminant plume while at the same
time putting the treated water to its highest use. In addition,
the South Plume will be extracted until ground water cleanup
standards are achieved. The cleanup standards are based upon the
ARARs identified for the remedy and upon the Minnesota RALs for
private potable water supplies. Extracted ground water will be
treated to meet MCLs and non-zero MCLGs established by the Safe
Drinking Water Act. The most carcinogenic and pervasive
compound, trichloroethene, will be reduced to 5 Mg/1 °r below,
which corresponds to a 1.7 x 10"6 cancer risk. The State of
Minnesota RAL will be the cleanup goal for 1,1- dichloroethane
because no Federal MCL/MCLG exists for this compound. The RAL
will be the cleanup goal for 1,1,-dichloroethene and 1,1,2-
trichloroethane because the affected aquifer may, in the future,
be used as a private potable water supply. The regulation of
water well drilling by the State of Minnesota is the
institutional control to be used to restrict drilling of private
wells in the South Plume before cleanup standards are achieved.
The point of compliance will be at the leading edge of the South
Plume. The area of attainment is considered to be the complete
areal and vertical extent of the South Plume. If contaminants of
concern reach static concentrations over a -period of time, the
extraction system will be evaluated to determine if alternate
pumping strategies would enhance contaminant recovery.
Groundwater monitoring will be required until restoration of the
aquifer is achieved and the extraction system is shut down.
Treatment residuals such as spent carbon and filter cake from the
metals precipitation process will be disposed of in accordance
with applicable Federal and State law. It is anticipated that
the spent carbon will be a characteristic hazardous waste under
RCRA. The metals precipitate can probably be handled as a solid
waste; proper disposal requirements will be determined during the
pilot test.
Unlike Alternative 2, Alternative 3 does not have the potential
to compromise the BGRS. Unlike Alternative 4, the ground water
resource is not wasted. In addition, the cost of Alternative 3
is roughly half that of Alternative 4.

The capital cost of the selected remedy is $2,249,000. The
annual operating cost is $276,000. The present worth of the
selected remedy, based on a 30-year period at a discount rate of
10%, is $4,851,000. Table 12 presents a more detailed breakdown
of the remedy's cost.
J. Statutory Determinations
This section discusses how the selected remedy for OU-3 meets the
five statutory requirements established by CERCLA.
Protection of Human Health and the Environment
The selected remedy will provide overall protection of human
health and the environment through extraction and treatment of
contaminated ground water. The extraction of the ground water
will contain the contaminant plume and restore the water quality
within the plume to drinking water standards. The extracted
water will be treated to meet drinking water standards and
discharged to a public water supply. Institutional controls on
the drilling of private wells will help to prevent consumption of
contaminated water before cleanup standards are achieved. The
remedy will attain a 10"* to 10"6 risk level for carcinogens. The
contaminated ground water does not exceed a noncarcinogenic
hazard index of one. No unacceptable short-term risks or cross-
media impacts will be caused by implementation of the remedy.
Compliance with ARARs
The selected remedy will comply with ARARs and TBCs. The
following is a list of ARARs and TBCs for the remedy:
Chemical Specific

Cost Effectiveness
The selected remedy provides an effective remedy proportionate to
its cost. The degree of long-term effectiveness and permanence,
reduction of mobility, toxicity, or volume of contaminants, and
ease of implementability, afforded by this remedy for the cost
make it a reasonable value.
Utilization of Permanent Solutions and Resource Recovery
Technologies to the Maximum Extent Practicable
The selected remedy meets the statutory requirement to utilize
permanent solutions and resource recovery technologies to the
maximum extent practicable.
The selected remedy, Alternative 3, provides the best balance
among the four alternatives with respect to the primary balancing
evaluation criteria. Alternative 3 provides a greater degree of
long-term effectiveness and permanence than Alternatives 2 and 4.
All alternatives provide a reduction in toxicity, mobility and
volume of contaminants. Alternative 3 will take the least amount
of time to implement and therefore is more effective in the
short-term than Alternatives 2 and 4. Alternative 3 is the least
costly and easier to implement than Alternatives 2 and 4. Of the
five primary balancing criteria, long-term effectiveness and
permanence, implementability and cost were the most decisive
-------
29
factors in the selection decision. Unlike Alternatives 2 and 4,
the selected remedy puts the treated ground water to its highest
beneficial use as potable water. By using the treated ground
water in the municipal water supply system of New Brighton, the
local contaminated ground water resource is recovered and the
uncontaminated local ground water resource is conserved. The
State of Minnesota and the community support the selected remedy
and would not support Alternatives 1, 2, or 4.
Preference for Treatment as a Principal Element
The selected remedy removes and treats VOCs in the ground water
using GAC. Therefore, it satisfies the statutory preference for
remedies that employ treatment as a principal element.
The selected remedy is protective of human health and the
environment, complies with ARARs, is cost-effective, utilizes
permanent solutions and resource recovery to the maximum extent
practicable, and satisfies the statutory preference for remedies
that employ treatment that reduces toxicity, mobility, or volume
as a principal element.
K. Documentation of Significant changes
The selected remedy is the preferred alternative presented in the
proposed plan. No significant changes were made to the preferred
alternative selected as the remedy for OU-3.

Notes:
The inhalation rales must be converted from m'/hr to L/minute for use in the shower model (Appendix E). To make the conversion, each
value must be multiplied by a factor of 914/60. The derivation of this factor is described in the text of Appendix C.
Calculation of exposure doses via dermal sorption also requires the use of permeability constants to determine how much of each chemical is
absorbed into the body. The use of permeability constants is discussed in Section II.C.2.
The value of 0.12 hours/day corresponds to 7 minutes/day.

TABLE 8 (continued)
The risk eslimatcs listed under this heading are for the child age group most at risk.
Probable = Probable exposure conditions
RME = Reasonable maximum exposure
Hazard index (HI) greater than 1, including at least one individual chemical with a hazard quotient (HQ) greater than 1. This HI
indicates the potential for adverse noncarcinogenic health effects via the associated exposure pathway.
HI greater than 1 with no chemical-specific HQ greater than 1, and no sum of chemical-specific HQs (effect-specific His)
associated with similar target organs or chemical effect are greater than 1. Because all effect-specific His are less than 1,
exposures via the associated pathway are not expected to result in adverse noncarcinogenic health effects.
HI greater than 1 with no chemical-specific HQ greater than 1, but at least one sum of chemical-specific HQs (effect-specific HI)
associated with similar target organs or chemical effect is greater than 1. Because at least one effect-specific HI is greater than 1,
exposure via the associated pathway has the potential to cause adverse health effects.
- = Used to represent upperbound excess cancer risks less than 1E-07 or noncarcinogenic risks (HQ and HI) less than 1E-
02.
ND = Not determined; the sum of chemical specific HQ across exposure pathways was not estimated due to the complexity of
evaluating noncarcinogenic effects associated with similar target organs or chemical effects. However, any combination of
exposure pathways which include chemical-specific HQ greater than 1 (footnoted d as discussed above) or including target
organs or chemical effect sums greater than 1 (footnoted f as discussed above) is associated with the potential for adverse
noncarcinogenic health effects.
NA = Not assessed; risks were not evaluated for these particular exposure pathways. (See discussion in Chapter 3).

Risk Factors
- Extrapolation
Most risk factors are extrapolated from animal lest results. Extrapolations may be
made for species, exposure dose, and exposure period; extrapolations are generally
conservative.
Adjustment of Oral Risk Factors
In order lo characterize risks from dermal exposures, generally expressed as absorbed
doses, oral risk factors are adjusted lo account for oral absorption efficiency.
- Slope Factors (SP)
SFs represent upper 95-percent confidence limit values; carcinogenic risks calculated
using SFs generally represent upper-bound estimates.
- Lack of Risk Factors
Risks from exposure lo chemicals with no available chemical-specific or substitute risk
factors cannot be quantitatively characterized.
Risk Summations
Risks from chemical mixtures are characterized by summing the individual chemical risks.
lliis procedure assumes thai chemicals have the same toxic end points and mechanisms of
action and do not interact, either syneigislically or antagonistically. These assumptions may
be incorrect.

Mainly used for source containment Technically
impractical to implement. Costly to construct.
Collects ground water and prevents future
migration. Will reduce levels of contamination over
time.
Technically impractical to implement at
these depths. Costly to construct.
Difficult to sustain process with low levels of
hydrocarbon feed from groundwater environment.
Unacceptable to MWCC due to hydraulic
loading.
Difficult to sustain process with low levels of
hydrocarbon feed from groundwater.
Effective in treating large array of organic
contaminants. Can be used as primary treatment or
as polisher in combination with other treatment
technologies.
Effective in removing volatile compounds.
Not as effective as air stripping. May require
additional polishing by other technology. Difficult
to implement due to space limitations.
High cost of materials.
Used to treat inorganic waste (i.e. metals),
therefore, not applicable at this Site.

applicable at this Site. Also, highly subject to
fouling by precipitates and biological growth.
May be effective in treating volatile compounds.
Presence of other nonvolatile compounds may
restrict use of this technology. Effectiveness is
difficult to evaluate. Large area needed.
High cost of power and materials compared to
similar acceptable technologies.
Acceleration of remediation. Reuse of extracted
groundwater. Pilot study required.
Cost effective. Groundwater must meet surface
water criteria prior to discharge. NPDES permit
required.
Would be restricted by operating permit of POTW.
May not be required if groundwater treated cm-Site.
Unacceptable to MWC.C due to hydraulic
loading concerns.
Redily irnplemcntable. Prudent use of
groundwater resource.
Reuse of extracted groundwater. No institutional
constraints.
