I. Introduction
EPA Region 8 is publishing this direct
final Notice of Deletion of the
International Smelting and Refining
Superfund Site, (Site), from the National
Priorities List (NPL). The NPL
constitutes Appendix B of 40 CFR part
300, which is the National Oil and
Hazardous Substances Pollution
Contingency Plan (NCP), which EPA
promulgated pursuant to section 105 of
the Comprehensive Environmental
Response, Compensation and Liability
Act (CERCLA) of 1980, as amended.
EPA maintains the NPL as the list of
sites that appear to present a significant
risk to public health, welfare, or the
environment. Sites on the NPL may be
the subject of remedial actions financed
by the Hazardous Substance Superfund
(Fund). As described in 300.425(e) (3) of
the NCP, sites deleted from the NPL
remain eligible for Fund-financed

Federal Register / Vol. 76, No. 154 / Wednesday, August 10, 2011 / Rules and Regulations
mstockstill on DSK4VPTVN1PROD with RULES
remedial actions if future conditions
warrant such actions.
Because EPA considers this action to
be noncontroversial and routine, this
action will be effective October 11, 2011
unless EPA receives adverse comments
by September 9, 2011. Along with this
direct final Notice of Deletion, EPA is
co-publishing a Notice of Intent to
Delete in the ‘‘Proposed Rules’’ section
of the Federal Register. If adverse
comments are received within the 30day public comment period on this
deletion action, EPA will publish a
timely withdrawal of this direct final
Notice of Deletion before the effective
date of the deletion, and the deletion
will not take effect. EPA will, as
appropriate, prepare a response to
comments and continue with the
deletion process on the basis of the
Notice of Intent to Delete and the
comments already received. There will
be no additional opportunity to
comment.
Section II of this document explains
the criteria for deleting sites from the
NPL. Section III discusses procedures
that EPA is using for this action. Section
IV discusses the International Smelting
and Refining (IS&R) Superfund Site and
demonstrates how it meets the deletion
criteria. Section V discusses EPA’s
action to delete the Site from the NPL
unless adverse comments are received
during the public comment period.
II. NPL Deletion Criteria
The NCP establishes the criteria that
EPA uses to delete sites from the NPL.
In accordance with 40 CFR 300.425(e),
sites may be deleted from the NPL
where no further response is
appropriate. In making such a
determination pursuant to 40 CFR
300.425(e), EPA will consider, in
consultation with the state, whether any
of the following criteria have been met:
i. Responsible parties or other persons
have implemented all appropriate
response actions required;
ii. All appropriate Fund-financed
response under CERCLA has been
implemented, and no further response
action by responsible parties is
appropriate; or
iii. The remedial investigation has
shown that the release poses no
significant threat to public health or the
environment and, therefore, the taking
of remedial measures is not appropriate.
Pursuant to CERCLA section 121(c)
and the NCP, EPA conducts five-year
reviews to ensure the continued
protectiveness of remedial actions
where hazardous substances, pollutants,
or contaminants remain at a site above
levels that allow for unlimited use and
unrestricted exposure. EPA conducts
VerDate Mar<15>2010
16:51 Aug 09, 2011
Jkt 223001
such five-year reviews even if a site is
deleted from the NPL. EPA may initiate
further action to ensure continued
protectiveness at a deleted site if new
information becomes available that
indicates it is appropriate. Whenever
there is a significant release from a site
deleted from the NPL, the deleted site
may be restored to the NPL without
application of the hazard ranking
system.
III. Deletion Procedures
The following procedures apply to
deletion of the Site:
(1) EPA consulted with the state of
Utah prior to developing this direct final
Notice of Deletion and the Notice of
Intent to Delete co-published today in
the ‘‘Proposed Rules’’ section of the
Federal Register.
(2) EPA has provided the State 30
working days for review of this notice
and the parallel Notice of Intent to
Delete prior to their publication today,
and the State, through the Utah
Department of Environmental Quality,
has concurred on the deletion of the Site
from the NPL.
(3) Concurrently with the publication
of this direct final Notice of Deletion, a
notice of the availability of the parallel
Notice of Intent to Delete is being
published in a major local newspaper,
Tooele Transcript Bulletin. The
newspaper notice announces the 30-day
public comment period concerning the
Notice of Intent to Delete the IS&R Site
from the NPL.
(4) The EPA placed copies of
documents supporting the proposed
deletion in the deletion docket and
made these items available for public
inspection and copying at the Site
information repositories identified
above.
(5) If adverse comments are received
within the 30-day public comment
period on this deletion action, EPA will
publish a timely notice of withdrawal of
this direct final Notice of Deletion
before its effective date and will prepare
a response to comments and continue
with the deletion process on the basis of
the Notice of Intent to Delete and the
comments already received.
Deletion of a site from the NPL does
not itself create, alter, or revoke any
individual’s rights or obligations.
Deletion of a site from the NPL does not
in any way alter EPA’s right to take
enforcement actions, as appropriate.
The NPL is designed primarily for
informational purposes and to assist
EPA management. Section 300.425(e)(3)
of the NCP states that the deletion of a
site from the NPL does not preclude
eligibility for future response actions,
PO 00000

should future conditions warrant such
actions.
IV. Basis for Site Deletion
The following information provides
EPA’s rationale for deleting the Site
from the NPL:
Site Background and History
The International Smelting & Refining
(IS&R) Superfund Site (Site ID
UTD093120921) is located
approximately two miles northeast of
Tooele, in Tooele County, Utah. The
Site occupies the lower portion of Pine
Canyon on the west flank of the Oquirrh
Mountains. The IS&R Site is comprised
of three areas:
1. The former smelter property and
surrounding land known as the Pine
Canyon Conservation Area, which is
owned by Atlantic Richfield Company,
Inc. (ARCO), and comprises the majority
of the Site;
2. Portions of the former Tooele
Valley Railroad (TVRR) grade that
extend from the Conservation Area to
the city of Tooele, Utah; and
3. Pine Canyon, a residential area
adjacent to the Conservation Area which
is locally referred to as Lincoln
Township.
The 3,000 acre Conservation Area
includes the 1,200 acre area once
occupied by the smelter and tailing
impoundments and all the adjacent
property owned by ARCO. ARCO, in
conjunction with the Utah Division of
Wildlife Resources (UDWR), created a
conservation easement in 1994 to
protect the reclaimed features. The
Conservation Area and the area
included within the conservation
easement are one and the same. The
current boundary for this Conservation
Area coincides with the ARCO property
boundary.
The TVRR grade portion of the Site is
the former railroad right-of-way running
from Vine Street in the City of Tooele
east to where the right-of-way intersects
the Conservation Area boundary. The
length of the former rail line is
approximately 10,000 feet, and because
the land use changes along the former
rail line from Tooele to the Conservation
Area, the TVRR grade was sectioned
into three study areas termed the
‘‘town,’’ ‘‘school’’’ and ‘‘extension’’
sections to reflect different land uses.
Pine Canyon occupies two square
miles and is located on the western edge
of the former IS&R smelter property.
There are approximately 135 properties
within the township with a population
of about 470 people. The Pine Canyon
community includes the properties that
were impacted by smelter operations.

Federal Register / Vol. 76, No. 154 / Wednesday, August 10, 2011 / Rules and Regulations
The IS&R Site was proposed for
addition to the NPL in the Federal
Register dated April 23, 1999 (FR
Volume 64, No. 78, pages 19968–19974).
The Site was made final on the NPL in
the Federal Register dated July 27, 2000
(FR Volume 65, No. 145, pages 46096–
46104). The existence of tailing
impoundments, smelter wastes and
contaminated surface soils and
groundwater were the principal reasons
for listing the IS&R Site. The
contaminants of concern are lead and
arsenic.
mstockstill on DSK4VPTVN1PROD with RULES
Conservation Area
IS&R began operations in Tooele in
1910 on approximately 1,200 acres. At
various times, from 1910 through 1972,
IS&R operated copper and lead smelters
and a lead-zinc flotation mill. In the
early years of IS&R operation, tailings
and slag were produced at an estimated
annual rate of 650,000 tons per year
with declining output in later years.
Approximately 326 acres of tailing of an
unknown volume are located within the
tailing impoundment. The copper
smelter was closed in 1946, followed by
the closure of the lead-zinc flotation
mill in 1968 and the lead smelter in
1972. With the exception of a few
incidental buildings, the smelter facility
was demolished or scrapped in the mid1970s.
From 1974 through 1981, the
Anaconda Company constructed and
operated a mine and mill known as the
Carr Fork Operation. The main mill of
the operation was one mile east of the
IS&R smelter property in Pine Canyon
on approximately 12.5 acres. The
operation began processing ore in 1979
and ran for less than two years. Tailings
from the operation were transported
down Pine Canyon to the original IS&R
tailing impoundment where a new 100foot high tailing dam was constructed.
Because of the short duration of
operations of the Carr Fork Mill, the
tailings encompass only about 64 acres
behind the constructed dam.
Pine Canyon/Lincoln Township
Lincoln was settled in the late 1800s
as a farming and ranching area. When
the smelter was constructed in 1908,
much of the original farm land was
purchased by the International Smelting
and Refining Company for operation of
the smelter. During the operational
period of the smelter, Lincoln continued
to be used for farming and also became
the residence for some smelter
employees. Since the smelter
discontinued operations in 1972, the
area has experienced a slow, steady
growth to its current population of
about 470 people.
VerDate Mar<15>2010
16:51 Aug 09, 2011
Jkt 223001
Lincoln Township was established in
1996 and operates as a separate
planning district within Tooele County.
Current land uses include residential,
recreational visitor and open
agricultural.
Tooele Valley Railroad (TVRR) Grade
The TVRR was constructed in 1909 to
connect the Union Pacific and Western
Pacific lines at Warner, Utah, (west of
Tooele) to the IS&R smelter—a distance
of approximately seven miles. The
primary reason for TVRR’s existence
was for the support of the IS&R smelter.
The railroad was used for transporting
smelter ores, concentrates, equipment,
and personnel to and from the Site.
Removal Actions
In 2003, maintenance activities were
performed by ARCO at the Carr Fork
Landfill Area which is near the east side
of the Site and is approximately six
acres in size. The landfill contains
mostly debris from the demolition phase
of the reclamation project which
occurred in 1986. Also, the Site
Entrance Stained Soils Area is near the
west side of the Site, near the point of
entry for Site visitors. The soils were of
a dark brownish tint, and the area was
approximately four acres in size.
Diversion berms were installed to
divert water flow away from the landfill
and steep canyon slopes. The landfill
area was grubbed and scarified in the
area where the diversion berms were to
be placed. Riprap was installed in areas
of high erosion potential. The Site
Entrance Area was grubbed and
scarified. The area was then covered
with 12 to 15 inches of compacted fill
material and revegetated. The project
was completed on June 20, 2003.
Additional detail can be found in the
Initial and Final Pollution Report dated
September 10, 2003.
In 2004 & 2005 a residential soil
Removal Action was conducted in
Lincoln Township/Pine Canyon.
Studies conducted as part of the
Remedial Investigation found that some
of the properties located in the Pine
Canyon community, west of the
Conservation Area, had been impacted
by smelter-related contaminants. Due to
high lead levels in a blood test taken by
the Tooele County Health Department
(TCHD) on a child in Pine Canyon and
the risks identified by the Baseline
Human Health Risk Assessment, EPA
and the UDEQ determined that
immediate implementation of a removal
action was necessary to reduce local
residents’ exposure to lead and arsenic
in the environment. In July 2004, EPA
issued a Unilateral Administrative
Order for a Time-Critical Removal
PO 00000
Frm 00048
Fmt 4700
Sfmt 4700
Action, to address all remaining
potential risks in the residential area.
The cleanup levels used were 580 mg/
kg lead and 100 mg/kg arsenic.
Excavation was completed on 19
residential properties and included
9,100 cubic yards of material removed
and transported to the tailing repository
on the smelter property. After
excavation, each property was
backfilled and landscaped or restored
similar to the pre-construction
condition. A Removal Action at the
railroad grade of the TVRR was
completed in the summer of 2005. The
railroad grade extends from Vine Street
in Tooele, east to where it divides into
two tracks and then intersects the
Conservation Area. For Removal Action
planning and remedial action, the
former grade was divided into three
corresponding sections that include the
town, school and extension sections.
A Unilateral Administrative Order
was issued by EPA to Atlantic Richfield
Company, Inc. (ARCO) on November 21,
2003. Under this order, ARCO
conducted field sampling to investigate
the degree and extent of the metals
impact on the grade. The sampling
results of relevant zones and areas that
exceeded cleanup levels were included
in the TVRR grade Removal Action. The
administrative order required removal
of up to 18 inches of soil in the town
and school sections where lead and
arsenic concentrations exceeded the
cleanup levels and removal or capping
of up to 18 inches of soil in the
extension sections. The human health
cleanup levels for these areas are 580
mg/kg lead and 100 mg/kg arsenic for
the town and school section soils and
2,231 mg/kg lead and 900 mg/kg arsenic
for the extension section soils.
In 2006, a Removal Action was
performed in the Conservation Area.
During the Remedial Investigation (RI)
for the Site, 18 locations of varying sizes
were identified in the Conservation
Area that exceeded the cleanup levels of
8,000 mg/kg lead and 900 mg/kg
arsenic.
The Conservation Area Removal
Action began in the fall of 2006 and was
completed during the spring of 2007.
Locations that exceeded cleanup levels
were addressed by placing a 12-inch
thick cap of clean soil over the
contaminated area and then reseeding
the surface. Two of the 18 locations
identified during the Remedial
Investigation were within the tailings
pile and could not be safely addressed
as a result of physical hazards.
Therefore, fencing and other physical
barriers were constructed to limit access
to these two locations. The Removal
Action also addressed areas where
E:\FR\FM\10AUR1.SGM
10AUR1
Federal Register / Vol. 76, No. 154 / Wednesday, August 10, 2011 / Rules and Regulations
vegetation was limited or absent and
contaminant concentrations were below
cleanup levels. These areas were
addressed by removing 24 inches of soil,
back-filling the excavation with clean
soil and reseeding. A thorough
discussion of the 2006 Conservation
Area Removal Action is included in the
2006 Conservation Area Removal Action
Final Construction Report dated June 1,
2007. Figure 2–4 of that report shows
the areas addressed by the 2006
Removal Actions.

Ongoing or Potential Development
The Conservation Area (ARCO
property) is designated as a wildlife
conservation area in accordance with an
easement agreement between ARCO and
the Utah Division of Wildlife Resources
(UDWR). The agreement precludes the
property from being used for purposes
other than the maintenance and
enhancement of wildlife indigenous to
the Oquirrh Range foothills. Activities
that would impact remedial features are
prohibited, such as drilling and
exploration, filling, excavating, mining,
dredging, and removal of top soil and
other materials, and commercial,
industrial, and agricultural use as set
forth in the conservation easement.
Before and since the easement was
originally issued in 1994, efforts have
been made to develop and protect this
area for wildlife purposes. The
management plan prepared by UDWR
and endorsed by ARCO defines uses and
periods of use allowable on the
property. In general, current use of the
area includes light recreational uses
such as walking, wildlife observation
and hunting. Motorized vehicles are not
permitted on Site except for
maintenance purposes, which is
enforced by the UDWR. The property is
fenced to prevent unauthorized use of
the area. Use of the area is not expected
to change in the future.
Current land uses within Pine Canyon
include residential, agricultural and
recreational designations. Though the
actual township boundaries are large in
area, the bulk of the population is
located along Ericson Road and near the
intersection of Blue Peak Drive and Pine
Canyon Road. Behind the houses are
large open fields used for farming and
pasture. The Boys Ranch parcel, a large
tract of open land to the northwest of
the Pine Canyon/Blue Peak Road
intersection, is planned for
development. Institutional controls have
been established to ensure that the
completed remedy and future
development of open land remains
protected.

Remedial Investigation (RI)
ARCO conducted the Remedial
Investigation (RI) between 2001 and
2006 with EPA oversight. The chief
objective of the RI was to determine the
potential risk to human health and the
environment of the IS&R Site and
adjacent land by evaluating the Site in
its current condition, taking into
account reclamation actions completed
in 1986, verifying previous investigation
sample results of the Site prior to
reclamation, and assessing conditions in
areas not previously addressed by
reclamation efforts including near-by
residential areas.
The Conservation Area was divided
into work areas during the RI to
facilitate the inspection. During the RI,
soils, slag, sediment, surface water and
groundwater were sampled, and Site
inspections were conducted to identify
areas where future remedial action may
be required. In addition to samples
collected on the former smelter site and
surrounding fields, residential yard
samples and household dust samples
were collected from selected residential
dwellings in the community of Pine
Canyon, located west of the smelter site.
The investigation monitored
groundwater wells in the area of the
smelter, Pine Canyon and nearby areas.
Soil and sediment samples were
analyzed for 23 metals and pH. The
metals included aluminum, antimony,
arsenic, barium, beryllium, cadmium,
calcium, chromium, cobalt, copper,
iron, lead, magnesium, manganese,
mercury, nickel, potassium, selenium,
silver, sodium, thallium, vanadium and
zinc. Water samples were analyzed for
the same 23 metals, 4 anions and 4
physical properties, including all
drinking water standards. Analytical
results of the samples collected show
that when lead and arsenic are high,
other metals may then be present in
concentrations high enough to pose a
concern. Therefore, throughout the
investigation, lead and arsenic were
used as indicator metals to gauge the
impact on areas from smelter
operations.
Groundwater samples were collected
on and near the Site from 2001 through
February 2006 to determine what
impact, if any, to area aquifers are a
result of past operations at the IS&R
Site, and in an attempt to locate a source
of elevated arsenic in the groundwater.
Findings of the Feasibility Study (FS)
The Feasibility Study concluded that
past Removal Actions had addressed
areas with soil containing
concentrations of contaminants of
concern above cleanup levels.
PO 00000
Frm 00049
Fmt 4700
Sfmt 4700

Institutional controls will be required to
ensure that the protectiveness of the
remedy is maintained. Monitoring of
groundwater will be required to
determine if arsenic concentrations
change, over time, relative to baseline
concentrations.
Selected Remedy
A Record of Decision (ROD) for the
Site was issued by EPA on September
27, 2007. The remedy established in the
ROD takes into account all removal
work and capped areas in the Carr Fork
Landfill Area, TVRR, and the
Conservation Area; selects the
implementation of institutional controls
and monitoring as needed to protect the
integrity of the previously completed
removal and reclamation actions; and
concludes that no further remedial
construction is necessary.
Remedial Action Objectives
Remedial Action Objectives (RAO) for
the Conservation Area, the TVRR grade
area, and Pine Canyon were achieved as
a result of the 2006 Conservation Area
Removal Action, the 2004 and 2005
Pine Canyon/Lincoln residential
Removal Action and the TVRR Removal
Action completed in the summer of
2005.
The RAOs identified for the Site
consisted of the following:
1. For human and ecological
receptors, prevent direct contact/
ingestion with soil having lead and/or
arsenic concentrations in excess of
cleanup levels identified for the Site,
and
2. For human and ecological
receptors, protect water quality in
stream by minimizing migration of soil
with lead and/or arsenic concentrations
above cleanup levels into streams.
RAOs were not necessary for surface
and ground water and sediments since
these media did not pose a risk to
human health and the environment.
RAOs for groundwater were not
necessary.
Response Actions
The findings of the Record of Decision
indicate that the Removal Actions
performed at the Site have addressed all
contamination that exceeds clean up
goals set for the Site.
Cleanup Goals
• Residential area soils do not exceed
580 mg/kg lead and 100 mg/kg arsenic
• Conservation area soils do not
exceed 8,000 mg/kg lead and 900 mg/kg
arsenic.
• TVRR Town and School Section
soils do not exceed 580 mg/kg lead and
100 mg/kg arsenic.

controls will be monitored to ensure
that they remain in place and serve their
intended purposes.
Operation and Maintenance
Five-Year Review
In accordance with CERCLA § 121 (c),
the Site is subject to statutory five-year
reviews since hazardous substances,
pollutants, or contaminants remain on
Site above levels that allow for
unlimited use and unrestricted
exposure. The first statutory five-year
review will be conducted in September
2012.
Operation and maintenance of the
Site is conducted by UDWR and ARCO
in accordance with the Long Term
Operation and Maintenance Plan (O&M
Plan 2010). ARCO is responsible for
O&M at the Site. Fence posts and wire
will be repaired and replaced as
necessary to maintain security of the
Site. This is especially important to
prevent motorized vehicles from
accessing the Site and damaging the
cover.
• Adequate signage has been placed
(and will be replaced as necessary)
around the perimeter Site fence to
instruct the public regarding
prohibited Site activities.
• An annual inspection is conducted at
the Site in May of each year (after
spring runoff season). The inspection
includes a photographic record and
looks at:
Æ Vegetation loss or obvious stressed
areas (seed and fertilizer is placed
as necessary)
Æ Vandalism of fences or signs, or
other evidence of unauthorized
trespassing
Æ Condition of culverts
Æ Erosion or other damage to the
protective soil cover
Æ Erosion of channels or other storm
water drainage control structure
• Items found deficient during the
inspections will be corrected to
protect the remedy at the Site as
outlined in the O&M Plan
Monitoring will be required for all
three areas of the Site. Monitoring by
ARCO will consist of inspecting the
integrity of the caps, covers and storm
water controls on an annual basis. The
UDWR will conduct day to day
surveillance as dictated in the Long
Term Operations and Maintenance Plan
and Conservation Easement.
Groundwater monitoring will be
conducted at the Conservation Area to
ensure that the former smelter area does
not become a source of groundwater
contamination in the future.

Community Involvement
Shortly after the Site was listed on the
NPL, an information repository
containing the Administrative Record
and other information about the Site
was established in 2000 at the Tooele
Public Library, 128 West Vine Street,
Tooele, Utah, and at the Superfund
Records Center at EPA Region 8 in
Denver. The UDEQ has numerous files
and information related to this Site,
which are available to the public upon
request; however, the UDEQ is not
considered an information repository for
the Site.
EPA and UDEQ completed a
community involvement plan for the
Site in November 2001. This plan
outlined methods to enhance
understanding and communication so
that those impacted can become more
informed about the Site activities and be
part of the decision making process. The
plan was based primarily on discussions
with residents, local officials and
business leaders, and it enlisted the
support of local groups, individuals and
elected officials to collect and distribute
information.
An informal community advisory
group was formed shortly after the Site
was placed on the NPL. Meetings have
been a joint effort between the EPA,
UDEQ, TCHD and citizens, and include
a citizen co-chair. Notices about the
meetings and the proposed agenda are
mailed and e-mailed to citizens in
advance of all meetings. Information is
also placed in the Tooele Transcript’s
event section known as the Bulletin
Board.
EPA and UDEQ have maintained
regular contact with members of the
community and implemented a variety
of community relations activities as new
information about the Site has become
available. This has included holding
public meetings; distributing fact sheets,
brochures and flyers; meeting with
community members and local officials;
developing and maintaining an EPA
Web fact sheet; and sharing information
with the local media. The EPA and
UDEQ supported the TCHD in
PO 00000
Frm 00050
Fmt 4700
Sfmt 4700
conducting a survey with residents
about the Site in 2001. EPA also worked
with the County to develop a brochure
that was distributed to residents in
2002.
EPA developed and distributed a fact
sheet in June 2004 to alert residents of
soil sampling activities. The fact sheet
included questions about health effects
of lead and arsenic in soil and included
tips to reduce exposure. It also informed
the community of the County’s services
for free blood testing.
The remedial investigation, feasibility
study reports and the proposed plan,
were released to the public for comment
on June 16, 2007. These documents
were made available to the public in
both the Administrative Record and the
informational repository described
above. In addition, approximately 100
copies of the proposed plan were mailed
to citizens in the neighborhoods
adjacent to the Site. The notice of
availability for the proposed plan was
published in the Tooele Transcript on
June 14, 2007. A public comment period
on the proposed plan was held from
June 16, 2007 to July 16, 2007.
A public meeting was held on June
26, 2007, at the TCHD regarding the
proposed plan for the Site. At this
meeting, representatives from EPA and
UDEQ answered questions about the
current condition of the Site, the
remedial alternatives under
consideration and the preferred
alternative. Several community
members, including the co-chair of the
community advisory group, expressed
support for the preferred alternative and
there were no objections to the preferred
alternative. EPA did not receive any
written comments during the comment
period.
Determination That the Site Meets the
Criteria for Deletion in the NCP
Four Removal Actions have been
completed at the Site. The Record of
Decision concluded that the removals
satisfied all remedial requirements at
the Site.
The Region has followed the
procedures required by 40 CFR
300.425(e) as follows:
1. Responsible parties or other
persons have implemented all
appropriate response actions required.
2. The state of Utah, through the Utah
Department of Environmental Quality
has concurred in the deletion of the Site
on August 25, 2010.
3. A Notice of Intent to Delete has
been published in the local newspaper.
4. Information supporting the
proposed deletion has been made
available in the information repository
for the Site.

V. Deletion Action
The EPA, with concurrence of the
state of Utah through the Utah
Department of Environmental Quality
(UDEQ), has determined that all
appropriate response actions under
CERCLA, other than operation,
maintenance, monitoring and five-year
reviews have been completed.
Therefore, EPA is deleting the Site from
the NPL.
Because EPA considers this action to
be noncontroversial and routine, EPA is
taking it without prior publication. This
action will be effective 45 days from the
date of this publication in the Federal
Register unless EPA receives adverse
comments within 30 days from this
publication in the Federal Register. If
adverse comments are received within
the 30-day public comment period, EPA
will publish a timely withdrawal of this
direct final Notice of Deletion before the
effective date of the deletion, and it will
not take effect. EPA will prepare a
response to comments and continue
with the deletion process on the basis of
the Notice of Intent to Delete and the
comments already received. There will
be no additional opportunity to
comment.

[Docket ID FEMA–2011–0002; Internal
Agency Docket No. FEMA–8191]
Suspension of Community Eligibility
AGENCY: Federal Emergency
Management Agency, DHS.
ACTION: Final rule.
SUMMARY: This rule identifies
communities, where the sale of flood
insurance has been authorized under
the National Flood Insurance Program
(NFIP), that are scheduled for
suspension on the effective dates listed
within this rule because of
noncompliance with the floodplain
management requirements of the
program. If the Federal Emergency
Management Agency (FEMA) receives
documentation that the community has
adopted the required floodplain
management measures prior to the
effective suspension date given in this
rule, the suspension will not occur and
a notice of this will be provided by
publication in the Federal Register on a
subsequent date.
DATES: Effective Dates: The effective
date of each community’s scheduled
suspension is the third date (‘‘Susp.’’)
listed in the third column of the
following tables.
FOR FURTHER INFORMATION CONTACT: If
you want to determine whether a
particular community was suspended
on the suspension date or for further
information, contact David Stearrett,
Mitigation Directorate, Federal
Emergency Management Agency, 500 C
Street, SW., Washington, DC 20472,
(202) 646–2953.
SUPPLEMENTARY INFORMATION: The NFIP
enables property owners to purchase
flood insurance which is generally not
otherwise available. In return,
communities agree to adopt and
administer local floodplain management
aimed at protecting lives and new
construction from future flooding.
Section 1315 of the National Flood
Insurance Act of 1968, as amended, 42
U.S.C. 4022, prohibits flood insurance
coverage as authorized under the NFIP,
42 U.S.C. 4001 et seq.; unless an
appropriate public body adopts
adequate floodplain management
measures with effective enforcement
measures. The communities listed in
this document no longer meet that
statutory requirement for compliance
PO 00000
Frm 00051
Fmt 4700
Sfmt 4700
49329
with program regulations, 44 CFR part
59. Accordingly, the communities will
be suspended on the effective date in
the third column. As of that date, flood
insurance will no longer be available in
the community. However, some of these
communities may adopt and submit the
required documentation of legally
enforceable floodplain management
measures after this rule is published but
prior to the actual suspension date.
These communities will not be
suspended and will continue their
eligibility for the sale of insurance. A
notice withdrawing the suspension of
the communities will be published in
the Federal Register.
In addition, FEMA has identified the
Special Flood Hazard Areas (SFHAs) in
these communities by publishing a
Flood Insurance Rate Map (FIRM). The
date of the FIRM, if one has been
published, is indicated in the fourth
column of the table. No direct Federal
financial assistance (except assistance
pursuant to the Robert T. Stafford
Disaster Relief and Emergency
Assistance Act not in connection with a
flood) may legally be provided for
construction or acquisition of buildings
in identified SFHAs for communities
not participating in the NFIP and
identified for more than a year, on
FEMA’s initial flood insurance map of
the community as having flood-prone
areas (section 202(a) of the Flood
Disaster Protection Act of 1973, 42
U.S.C. 4106(a), as amended). This
prohibition against certain types of
Federal assistance becomes effective for
the communities listed on the date
shown in the last column. The
Administrator finds that notice and
public comment under 5 U.S.C. 553(b)
are impracticable and unnecessary
because communities listed in this final
rule have been adequately notified.
Each community receives 6-month,
90-day, and 30-day notification letters
addressed to the Chief Executive Officer
stating that the community will be
suspended unless the required
floodplain management measures are
met prior to the effective suspension
date. Since these notifications were
made, this final rule may take effect
within less than 30 days.
National Environmental Policy Act.
This rule is categorically excluded from
the requirements of 44 CFR part 10,
Environmental Considerations. No
environmental impact assessment has
been prepared.

Administrator has determined that this
rule is exempt from the requirements of
the Regulatory Flexibility Act because

ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) Region 8 is
publishing a direct final Notice of Deletion of the International
Smelting and Refining Superfund Site (Site), located in Tooele, Utah,
from the National Priorities List (NPL). The NPL, promulgated pursuant
to section 105 of the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) of 1980, as amended, is an
appendix of the National Oil and Hazardous Substances Pollution
Contingency Plan (NCP). This direct final deletion is being published
by EPA with the concurrence of the state of Utah, through the Utah
Department of Environmental Quality (UDEQ) because EPA has determined
that all appropriate response actions under CERCLA, other than
operation, maintenance, and five-year reviews, have been completed.
However, this deletion does not preclude future actions under
Superfund.
DATES: This direct final deletion is effective October 11, 2011 unless
EPA receives adverse comments by September 9, 2011. If adverse comments
are received, EPA will publish a timely withdrawal of the direct final

V. Deletion Action
I. Introduction
EPA Region 8 is publishing this direct final Notice of Deletion of
the International Smelting and Refining Superfund Site, (Site), from
the National Priorities List (NPL). The NPL constitutes Appendix B of
40 CFR part 300, which is the National Oil and Hazardous Substances
Pollution Contingency Plan (NCP), which EPA promulgated pursuant to
section 105 of the Comprehensive Environmental Response, Compensation
and Liability Act (CERCLA) of 1980, as amended. EPA maintains the NPL
as the list of sites that appear to present a significant risk to
public health, welfare, or the environment. Sites on the NPL may be the
subject of remedial actions financed by the Hazardous Substance
Superfund (Fund). As described in 300.425(e) (3) of the NCP, sites
deleted from the NPL remain eligible for Fund-financed
[[Page 49325]]
remedial actions if future conditions warrant such actions.
Because EPA considers this action to be noncontroversial and
routine, this action will be effective October 11, 2011 unless EPA
receives adverse comments by September 9, 2011. Along with this direct
final Notice of Deletion, EPA is co-publishing a Notice of Intent to
Delete in the ``Proposed Rules'' section of the Federal Register. If
adverse comments are received within the 30-day public comment period
on this deletion action, EPA will publish a timely withdrawal of this
direct final Notice of Deletion before the effective date of the
deletion, and the deletion will not take effect. EPA will, as
appropriate, prepare a response to comments and continue with the
deletion process on the basis of the Notice of Intent to Delete and the
comments already received. There will be no additional opportunity to
comment.
Section II of this document explains the criteria for deleting
sites from the NPL. Section III discusses procedures that EPA is using
for this action. Section IV discusses the International Smelting and
Refining (IS&R) Superfund Site and demonstrates how it meets the
deletion criteria. Section V discusses EPA's action to delete the Site
from the NPL unless adverse comments are received during the public
comment period.
II. NPL Deletion Criteria
The NCP establishes the criteria that EPA uses to delete sites from
the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted
from the NPL where no further response is appropriate. In making such a
determination pursuant to 40 CFR 300.425(e), EPA will consider, in
consultation with the state, whether any of the following criteria have
been met:
i. Responsible parties or other persons have implemented all
appropriate response actions required;
ii. All appropriate Fund-financed response under CERCLA has been
implemented, and no further response action by responsible parties is
appropriate; or
iii. The remedial investigation has shown that the release poses no
significant threat to public health or the environment and, therefore,
the taking of remedial measures is not appropriate.
Pursuant to CERCLA section 121(c) and the NCP, EPA conducts five-
year reviews to ensure the continued protectiveness of remedial actions
where hazardous substances, pollutants, or contaminants remain at a
site above levels that allow for unlimited use and unrestricted
exposure. EPA conducts such five-year reviews even if a site is deleted
from the NPL. EPA may initiate further action to ensure continued
protectiveness at a deleted site if new information becomes available
that indicates it is appropriate. Whenever there is a significant
release from a site deleted from the NPL, the deleted site may be
restored to the NPL without application of the hazard ranking system.
III. Deletion Procedures
The following procedures apply to deletion of the Site:
(1) EPA consulted with the state of Utah prior to developing this
direct final Notice of Deletion and the Notice of Intent to Delete co-
published today in the ``Proposed Rules'' section of the Federal
Register.
(2) EPA has provided the State 30 working days for review of this
notice and the parallel Notice of Intent to Delete prior to their
publication today, and the State, through the Utah Department of
Environmental Quality, has concurred on the deletion of the Site from
the NPL.
(3) Concurrently with the publication of this direct final Notice
of Deletion, a notice of the availability of the parallel Notice of
Intent to Delete is being published in a major local newspaper, Tooele
Transcript Bulletin. The newspaper notice announces the 30-day public
comment period concerning the Notice of Intent to Delete the IS&R Site
from the NPL.
(4) The EPA placed copies of documents supporting the proposed
deletion in the deletion docket and made these items available for
public inspection and copying at the Site information repositories
identified above.
(5) If adverse comments are received within the 30-day public
comment period on this deletion action, EPA will publish a timely
notice of withdrawal of this direct final Notice of Deletion before its
effective date and will prepare a response to comments and continue
with the deletion process on the basis of the Notice of Intent to
Delete and the comments already received.
Deletion of a site from the NPL does not itself create, alter, or
revoke any individual's rights or obligations. Deletion of a site from
the NPL does not in any way alter EPA's right to take enforcement
actions, as appropriate. The NPL is designed primarily for
informational purposes and to assist EPA management. Section
300.425(e)(3) of the NCP states that the deletion of a site from the
NPL does not preclude eligibility for future response actions, should
future conditions warrant such actions.
IV. Basis for Site Deletion
The following information provides EPA's rationale for deleting the
Site from the NPL:
Site Background and History
The International Smelting & Refining (IS&R) Superfund Site (Site
ID UTD093120921) is located approximately two miles northeast of
Tooele, in Tooele County, Utah. The Site occupies the lower portion of
Pine Canyon on the west flank of the Oquirrh Mountains. The IS&R Site
is comprised of three areas:
1. The former smelter property and surrounding land known as the
Pine Canyon Conservation Area, which is owned by Atlantic Richfield
Company, Inc. (ARCO), and comprises the majority of the Site;
2. Portions of the former Tooele Valley Railroad (TVRR) grade that
extend from the Conservation Area to the city of Tooele, Utah; and
3. Pine Canyon, a residential area adjacent to the Conservation
Area which is locally referred to as Lincoln Township.
The 3,000 acre Conservation Area includes the 1,200 acre area once
occupied by the smelter and tailing impoundments and all the adjacent
property owned by ARCO. ARCO, in conjunction with the Utah Division of
Wildlife Resources (UDWR), created a conservation easement in 1994 to
protect the reclaimed features. The Conservation Area and the area
included within the conservation easement are one and the same. The
current boundary for this Conservation Area coincides with the ARCO
property boundary.
The TVRR grade portion of the Site is the former railroad right-of-
way running from Vine Street in the City of Tooele east to where the
right-of-way intersects the Conservation Area boundary. The length of
the former rail line is approximately 10,000 feet, and because the land
use changes along the former rail line from Tooele to the Conservation
Area, the TVRR grade was sectioned into three study areas termed the
``town,'' ``school''' and ``extension'' sections to reflect different
land uses.
Pine Canyon occupies two square miles and is located on the western
edge of the former IS&R smelter property. There are approximately 135
properties within the township with a population of about 470 people.
The Pine Canyon community includes the properties that were impacted by
smelter operations.
[[Page 49326]]
The IS&R Site was proposed for addition to the NPL in the Federal
Register dated April 23, 1999 (FR Volume 64, No. 78, pages 19968-
19974). The Site was made final on the NPL in the Federal Register
dated July 27, 2000 (FR Volume 65, No. 145, pages 46096-46104). The
existence of tailing impoundments, smelter wastes and contaminated
surface soils and groundwater were the principal reasons for listing
the IS&R Site. The contaminants of concern are lead and arsenic.
Conservation Area
IS&R began operations in Tooele in 1910 on approximately 1,200
acres. At various times, from 1910 through 1972, IS&R operated copper
and lead smelters and a lead-zinc flotation mill. In the early years of
IS&R operation, tailings and slag were produced at an estimated annual
rate of 650,000 tons per year with declining output in later years.
Approximately 326 acres of tailing of an unknown volume are located
within the tailing impoundment. The copper smelter was closed in 1946,
followed by the closure of the lead-zinc flotation mill in 1968 and the
lead smelter in 1972. With the exception of a few incidental buildings,
the smelter facility was demolished or scrapped in the mid-1970s.
From 1974 through 1981, the Anaconda Company constructed and
operated a mine and mill known as the Carr Fork Operation. The main
mill of the operation was one mile east of the IS&R smelter property in
Pine Canyon on approximately 12.5 acres. The operation began processing
ore in 1979 and ran for less than two years. Tailings from the
operation were transported down Pine Canyon to the original IS&R
tailing impoundment where a new 100-foot high tailing dam was
constructed. Because of the short duration of operations of the Carr
Fork Mill, the tailings encompass only about 64 acres behind the
constructed dam.
Pine Canyon/Lincoln Township
Lincoln was settled in the late 1800s as a farming and ranching
area. When the smelter was constructed in 1908, much of the original
farm land was purchased by the International Smelting and Refining
Company for operation of the smelter. During the operational period of
the smelter, Lincoln continued to be used for farming and also became
the residence for some smelter employees. Since the smelter
discontinued operations in 1972, the area has experienced a slow,
steady growth to its current population of about 470 people.
Lincoln Township was established in 1996 and operates as a separate
planning district within Tooele County. Current land uses include
residential, recreational visitor and open agricultural.
Tooele Valley Railroad (TVRR) Grade
The TVRR was constructed in 1909 to connect the Union Pacific and
Western Pacific lines at Warner, Utah, (west of Tooele) to the IS&R
smelter--a distance of approximately seven miles. The primary reason
for TVRR's existence was for the support of the IS&R smelter. The
railroad was used for transporting smelter ores, concentrates,
equipment, and personnel to and from the Site.
Removal Actions
In 2003, maintenance activities were performed by ARCO at the Carr
Fork Landfill Area which is near the east side of the Site and is
approximately six acres in size. The landfill contains mostly debris
from the demolition phase of the reclamation project which occurred in
1986. Also, the Site Entrance Stained Soils Area is near the west side
of the Site, near the point of entry for Site visitors. The soils were
of a dark brownish tint, and the area was approximately four acres in
size.
Diversion berms were installed to divert water flow away from the
landfill and steep canyon slopes. The landfill area was grubbed and
scarified in the area where the diversion berms were to be placed.
Riprap was installed in areas of high erosion potential. The Site
Entrance Area was grubbed and scarified. The area was then covered with
12 to 15 inches of compacted fill material and revegetated. The project
was completed on June 20, 2003. Additional detail can be found in the
Initial and Final Pollution Report dated September 10, 2003.
In 2004 & 2005 a residential soil Removal Action was conducted in
Lincoln Township/Pine Canyon. Studies conducted as part of the Remedial
Investigation found that some of the properties located in the Pine
Canyon community, west of the Conservation Area, had been impacted by
smelter-related contaminants. Due to high lead levels in a blood test
taken by the Tooele County Health Department (TCHD) on a child in Pine
Canyon and the risks identified by the Baseline Human Health Risk
Assessment, EPA and the UDEQ determined that immediate implementation
of a removal action was necessary to reduce local residents' exposure
to lead and arsenic in the environment. In July 2004, EPA issued a
Unilateral Administrative Order for a Time-Critical Removal Action, to
address all remaining potential risks in the residential area. The
cleanup levels used were 580 mg/kg lead and 100 mg/kg arsenic.
Excavation was completed on 19 residential properties and included
9,100 cubic yards of material removed and transported to the tailing
repository on the smelter property. After excavation, each property was
backfilled and landscaped or restored similar to the pre-construction
condition. A Removal Action at the railroad grade of the TVRR was
completed in the summer of 2005. The railroad grade extends from Vine
Street in Tooele, east to where it divides into two tracks and then
intersects the Conservation Area. For Removal Action planning and
remedial action, the former grade was divided into three corresponding
sections that include the town, school and extension sections.
A Unilateral Administrative Order was issued by EPA to Atlantic
Richfield Company, Inc. (ARCO) on November 21, 2003. Under this order,
ARCO conducted field sampling to investigate the degree and extent of
the metals impact on the grade. The sampling results of relevant zones
and areas that exceeded cleanup levels were included in the TVRR grade
Removal Action. The administrative order required removal of up to 18
inches of soil in the town and school sections where lead and arsenic
concentrations exceeded the cleanup levels and removal or capping of up
to 18 inches of soil in the extension sections. The human health
cleanup levels for these areas are 580 mg/kg lead and 100 mg/kg arsenic
for the town and school section soils and 2,231 mg/kg lead and 900 mg/
kg arsenic for the extension section soils.
In 2006, a Removal Action was performed in the Conservation Area.
During the Remedial Investigation (RI) for the Site, 18 locations of
varying sizes were identified in the Conservation Area that exceeded
the cleanup levels of 8,000 mg/kg lead and 900 mg/kg arsenic.
The Conservation Area Removal Action began in the fall of 2006 and
was completed during the spring of 2007. Locations that exceeded
cleanup levels were addressed by placing a 12-inch thick cap of clean
soil over the contaminated area and then reseeding the surface. Two of
the 18 locations identified during the Remedial Investigation were
within the tailings pile and could not be safely addressed as a result
of physical hazards. Therefore, fencing and other physical barriers
were constructed to limit access to these two locations. The Removal
Action also addressed areas where
[[Page 49327]]
vegetation was limited or absent and contaminant concentrations were
below cleanup levels. These areas were addressed by removing 24 inches
of soil, back-filling the excavation with clean soil and reseeding. A
thorough discussion of the 2006 Conservation Area Removal Action is
included in the 2006 Conservation Area Removal Action Final
Construction Report dated June 1, 2007. Figure 2-4 of that report shows
the areas addressed by the 2006 Removal Actions.
Ongoing or Potential Development
The Conservation Area (ARCO property) is designated as a wildlife
conservation area in accordance with an easement agreement between ARCO
and the Utah Division of Wildlife Resources (UDWR). The agreement
precludes the property from being used for purposes other than the
maintenance and enhancement of wildlife indigenous to the Oquirrh Range
foothills. Activities that would impact remedial features are
prohibited, such as drilling and exploration, filling, excavating,
mining, dredging, and removal of top soil and other materials, and
commercial, industrial, and agricultural use as set forth in the
conservation easement. Before and since the easement was originally
issued in 1994, efforts have been made to develop and protect this area
for wildlife purposes. The management plan prepared by UDWR and
endorsed by ARCO defines uses and periods of use allowable on the
property. In general, current use of the area includes light
recreational uses such as walking, wildlife observation and hunting.
Motorized vehicles are not permitted on Site except for maintenance
purposes, which is enforced by the UDWR. The property is fenced to
prevent unauthorized use of the area. Use of the area is not expected
to change in the future.
Current land uses within Pine Canyon include residential,
agricultural and recreational designations. Though the actual township
boundaries are large in area, the bulk of the population is located
along Ericson Road and near the intersection of Blue Peak Drive and
Pine Canyon Road. Behind the houses are large open fields used for
farming and pasture. The Boys Ranch parcel, a large tract of open land
to the northwest of the Pine Canyon/Blue Peak Road intersection, is
planned for development. Institutional controls have been established
to ensure that the completed remedy and future development of open land
remains protected.
Remedial Investigation (RI)
ARCO conducted the Remedial Investigation (RI) between 2001 and
2006 with EPA oversight. The chief objective of the RI was to determine
the potential risk to human health and the environment of the IS&R Site
and adjacent land by evaluating the Site in its current condition,
taking into account reclamation actions completed in 1986, verifying
previous investigation sample results of the Site prior to reclamation,
and assessing conditions in areas not previously addressed by
reclamation efforts including near-by residential areas.
The Conservation Area was divided into work areas during the RI to
facilitate the inspection. During the RI, soils, slag, sediment,
surface water and groundwater were sampled, and Site inspections were
conducted to identify areas where future remedial action may be
required. In addition to samples collected on the former smelter site
and surrounding fields, residential yard samples and household dust
samples were collected from selected residential dwellings in the
community of Pine Canyon, located west of the smelter site. The
investigation monitored groundwater wells in the area of the smelter,
Pine Canyon and nearby areas.
Soil and sediment samples were analyzed for 23 metals and pH. The
metals included aluminum, antimony, arsenic, barium, beryllium,
cadmium, calcium, chromium, cobalt, copper, iron, lead, magnesium,
manganese, mercury, nickel, potassium, selenium, silver, sodium,
thallium, vanadium and zinc. Water samples were analyzed for the same
23 metals, 4 anions and 4 physical properties, including all drinking
water standards. Analytical results of the samples collected show that
when lead and arsenic are high, other metals may then be present in
concentrations high enough to pose a concern. Therefore, throughout the
investigation, lead and arsenic were used as indicator metals to gauge
the impact on areas from smelter operations.
Groundwater samples were collected on and near the Site from 2001
through February 2006 to determine what impact, if any, to area
aquifers are a result of past operations at the IS&R Site, and in an
attempt to locate a source of elevated arsenic in the groundwater.
Findings of the Feasibility Study (FS)
The Feasibility Study concluded that past Removal Actions had
addressed areas with soil containing concentrations of contaminants of
concern above cleanup levels. Institutional controls will be required
to ensure that the protectiveness of the remedy is maintained.
Monitoring of groundwater will be required to determine if arsenic
concentrations change, over time, relative to baseline concentrations.
Selected Remedy
A Record of Decision (ROD) for the Site was issued by EPA on
September 27, 2007. The remedy established in the ROD takes into
account all removal work and capped areas in the Carr Fork Landfill
Area, TVRR, and the Conservation Area; selects the implementation of
institutional controls and monitoring as needed to protect the
integrity of the previously completed removal and reclamation actions;
and concludes that no further remedial construction is necessary.
Remedial Action Objectives
Remedial Action Objectives (RAO) for the Conservation Area, the
TVRR grade area, and Pine Canyon were achieved as a result of the 2006
Conservation Area Removal Action, the 2004 and 2005 Pine Canyon/Lincoln
residential Removal Action and the TVRR Removal Action completed in the
summer of 2005.
The RAOs identified for the Site consisted of the following:
1. For human and ecological receptors, prevent direct contact/
ingestion with soil having lead and/or arsenic concentrations in excess
of cleanup levels identified for the Site, and
2. For human and ecological receptors, protect water quality in
stream by minimizing migration of soil with lead and/or arsenic
concentrations above cleanup levels into streams.
RAOs were not necessary for surface and ground water and sediments
since these media did not pose a risk to human health and the
environment. RAOs for groundwater were not necessary.
Response Actions
The findings of the Record of Decision indicate that the Removal
Actions performed at the Site have addressed all contamination that
exceeds clean up goals set for the Site.
Cleanup Goals
Residential area soils do not exceed 580 mg/kg lead and
100 mg/kg arsenic
Conservation area soils do not exceed 8,000 mg/kg lead and
900 mg/kg arsenic.
TVRR Town and School Section soils do not exceed 580 mg/kg
lead and 100 mg/kg arsenic.
[[Page 49328]]
TVRR Extension Section soils do not exceed 2,300 mg/kg
lead and 900 mg/kg arsenic.
Operation and Maintenance
Operation and maintenance of the Site is conducted by UDWR and ARCO
in accordance with the Long Term Operation and Maintenance Plan (O&M
Plan 2010). ARCO is responsible for O&M at the Site. Fence posts and
wire will be repaired and replaced as necessary to maintain security of
the Site. This is especially important to prevent motorized vehicles
from accessing the Site and damaging the cover.
Adequate signage has been placed (and will be replaced as
necessary) around the perimeter Site fence to instruct the public
regarding prohibited Site activities.
An annual inspection is conducted at the Site in May of each
year (after spring runoff season). The inspection includes a
photographic record and looks at:
[cir] Vegetation loss or obvious stressed areas (seed and
fertilizer is placed as necessary)
[cir] Vandalism of fences or signs, or other evidence of
unauthorized trespassing
[cir] Condition of culverts
[cir] Erosion or other damage to the protective soil cover
[cir] Erosion of channels or other storm water drainage control
structure
Items found deficient during the inspections will be corrected
to protect the remedy at the Site as outlined in the O&M Plan
Monitoring will be required for all three areas of the Site.
Monitoring by ARCO will consist of inspecting the integrity of the
caps, covers and storm water controls on an annual basis. The UDWR will
conduct day to day surveillance as dictated in the Long Term Operations
and Maintenance Plan and Conservation Easement. Groundwater monitoring
will be conducted at the Conservation Area to ensure that the former
smelter area does not become a source of groundwater contamination in
the future.
Institutional Controls
ARCO will assist the TCHD in administering the institutional
controls, which regulate the development of land within an overlay zone
in Pine Canyon where soils could potentially have elevated
concentrations of lead and/or arsenic. This includes providing
information and review if necessary, of sampling and analysis plans
prepared by land developers. Institutional controls will be monitored
to ensure that they remain in place and serve their intended purposes.
Five-Year Review
In accordance with CERCLA Sec. 121 (c), the Site is subject to
statutory five-year reviews since hazardous substances, pollutants, or
contaminants remain on Site above levels that allow for unlimited use
and unrestricted exposure. The first statutory five-year review will be
conducted in September 2012.
Community Involvement
Shortly after the Site was listed on the NPL, an information
repository containing the Administrative Record and other information
about the Site was established in 2000 at the Tooele Public Library,
128 West Vine Street, Tooele, Utah, and at the Superfund Records Center
at EPA Region 8 in Denver. The UDEQ has numerous files and information
related to this Site, which are available to the public upon request;
however, the UDEQ is not considered an information repository for the
Site.
EPA and UDEQ completed a community involvement plan for the Site in
November 2001. This plan outlined methods to enhance understanding and
communication so that those impacted can become more informed about the
Site activities and be part of the decision making process. The plan
was based primarily on discussions with residents, local officials and
business leaders, and it enlisted the support of local groups,
individuals and elected officials to collect and distribute
information.
An informal community advisory group was formed shortly after the
Site was placed on the NPL. Meetings have been a joint effort between
the EPA, UDEQ, TCHD and citizens, and include a citizen co-chair.
Notices about the meetings and the proposed agenda are mailed and e-
mailed to citizens in advance of all meetings. Information is also
placed in the Tooele Transcript's event section known as the Bulletin
Board.
EPA and UDEQ have maintained regular contact with members of the
community and implemented a variety of community relations activities
as new information about the Site has become available. This has
included holding public meetings; distributing fact sheets, brochures
and flyers; meeting with community members and local officials;
developing and maintaining an EPA Web fact sheet; and sharing
information with the local media. The EPA and UDEQ supported the TCHD
in conducting a survey with residents about the Site in 2001. EPA also
worked with the County to develop a brochure that was distributed to
residents in 2002.
EPA developed and distributed a fact sheet in June 2004 to alert
residents of soil sampling activities. The fact sheet included
questions about health effects of lead and arsenic in soil and included
tips to reduce exposure. It also informed the community of the County's
services for free blood testing.
The remedial investigation, feasibility study reports and the
proposed plan, were released to the public for comment on June 16,
2007. These documents were made available to the public in both the
Administrative Record and the informational repository described above.
In addition, approximately 100 copies of the proposed plan were mailed
to citizens in the neighborhoods adjacent to the Site. The notice of
availability for the proposed plan was published in the Tooele
Transcript on June 14, 2007. A public comment period on the proposed
plan was held from June 16, 2007 to July 16, 2007.
A public meeting was held on June 26, 2007, at the TCHD regarding
the proposed plan for the Site. At this meeting, representatives from
EPA and UDEQ answered questions about the current condition of the
Site, the remedial alternatives under consideration and the preferred
alternative. Several community members, including the co-chair of the
community advisory group, expressed support for the preferred
alternative and there were no objections to the preferred alternative.
EPA did not receive any written comments during the comment period.
Determination That the Site Meets the Criteria for Deletion in the NCP
Four Removal Actions have been completed at the Site. The Record of
Decision concluded that the removals satisfied all remedial
requirements at the Site.
The Region has followed the procedures required by 40 CFR
300.425(e) as follows:
1. Responsible parties or other persons have implemented all
appropriate response actions required.
2. The state of Utah, through the Utah Department of Environmental
Quality has concurred in the deletion of the Site on August 25, 2010.
3. A Notice of Intent to Delete has been published in the local
newspaper.
4. Information supporting the proposed deletion has been made
available in the information repository for the Site.
[[Page 49329]]
V. Deletion Action
The EPA, with concurrence of the state of Utah through the Utah
Department of Environmental Quality (UDEQ), has determined that all
appropriate response actions under CERCLA, other than operation,
maintenance, monitoring and five-year reviews have been completed.
Therefore, EPA is deleting the Site from the NPL.
Because EPA considers this action to be noncontroversial and
routine, EPA is taking it without prior publication. This action will
be effective 45 days from the date of this publication in the Federal
Register unless EPA receives adverse comments within 30 days from this
publication in the Federal Register. If adverse comments are received
within the 30-day public comment period, EPA will publish a timely
withdrawal of this direct final Notice of Deletion before the effective
date of the deletion, and it will not take effect. EPA will prepare a
response to comments and continue with the deletion process on the
basis of the Notice of Intent to Delete and the comments already
received. There will be no additional opportunity to comment.
