Addressing Community Needs in
East Helena, Montana

Environmental Enforcement
Benefits the Community

The Value of Environmental Enforcement

At the East Helena Superfund site in East Helena,
Montana, EPA's environmental enforcement mechanisms
and resources have played a vital role in protecting
public health, achieving environmental restoration, and
supporting reuse of these highly contaminated properties.
EPA used its enforcement first policy to achieve long-
term community benefits for East Helena.

EPA's environmental enforcement program worked to
ensure liable parties implemented response actions
and corrective measures at the East Helena site. EPA
enforcement staff proactively and creatively secured
funding for cleanup through a nationwide settlement
with a potentially responsible party (PRP), the American
Smelting and Refining Company (ASARCO), lessening
the burden on taxpayers. The extensive and complicated
cleanup of over 1,500 properties has been instrumental
for the health of area residents, for local livelihoods, and
for the protection and revitalization of the environment.

Today, hundreds of properties in East Helena remain in
use where EPA has overseen cleanup. Remedial efforts
at the site are ongoing. EPA continues to work with the
community to incorporate future land use priorities into
its cleanup decisions.

Environmental and public health impacts affect people
most significantly where they live. EPA works to provide
strong, effective enforcement support to all communities.
As the Agency implements environmental and public
health improvements across the country, EPA is looking
for new ways to assist communities in environmentally
overburdened, underserved, and economically
distressed areas where the needs are greatest.

During decades of collaborative efforts, EPA and its partners have kept residents
safe and supported opportunities for reuse in the East Helena community.

Enforcement First:

Polluters Pay, Not Taxpayers

EPA enforcement makes sure that responsible
parties meet their obligations under the nation's
environmental laws to protect public health and the
environment, Using the enforcement first approach,
EPA identifies parties responsible for contamination
and compels them to clean it up or pay for the
cleanup, and works with diverse stakeholders to
ensure the long-term protectiveness of public health
and the environment. The enforcement program
also supports community revitalization by providing
guidance materials and site-specific tools that help
stakeholders address liability concerns and plan for
the future.

What are the Health Effects of Lead in Children?

Lead can affect almost every organ and system in the
human body. Children six years old and younger are
most susceptible to the effects of lead.

Even low levels of lead in the blood of children can
result in:

•	Behavior and learning problems

•	Lower IQand hyperactivity

•	Slowed growth

•	Hearing problems

•	Anemia

In rare cases, ingestion of lead can cause seizures,
coma and even death.

Site and Community Overview

The site consists of the 140-acre former lead smelter
facility and about 2,000 acres surrounding the smelter
in East Helena, Montana. These 2,000 acres include
the City of East Helena, residential subdivisions, rural

homes and farms, and undeveloped land. ASARCO
began lead and zinc smelting operations in 1888
and continued for over 100 years. Those operations
released lead, arsenic, copper, zinc, cadmium and
other heavy metals into the air, soil, surface water, and
groundwater across the Helena Valley. ASARCO shut
down the smelter in 2001.

In 1927, the Anaconda Company built a plant next to
the ASARCO smelter to recover zinc from the smelter's
waste slag. ASARCO bought the plant in 1972
and operated it until its closure in 1982. ASARCO
owned the smelter facility grounds and much of the
undeveloped land around East Helena. In 1955, the
American Chemet Corporation began producing zinc-
based paint pigments at a facility next to the smelter
property. Chemet still operates a manufacturing plant
that produces copper and zinc products such as copper-
based powders, copper and zinc oxides, and metal
fungicides.

As the engine of the local economy, the smelter helped
define the area's cultural heritage; the community grew
up around the smelter. The State of Montana began
conducting site investigations as early as 1969. Since
then, federal and state cleanup efforts have addressed
and continue to address the widespread contamination
of soils, surface water, and groundwater throughout the
facility, East Helena, and Lewis and Clark County.

Project History

1969 - 1990s

Defining Site Areas, Moving Forward with
Superfund and Resource Conservation and
Recovery Act (RCRA) Actions

Investigations by EPA and the state found high metal
levels in air, soil, surface water and dust in and around
East Helena. In 1975, the Montana Department of
Health and Environmental Sciences (MDHES) and the
National Centers for Disease Control and Prevention
conducted the first blood-lead studies of residents in
the area and found some area children had high blood-
lead levels.

-------
ASARCO, the PRP, installed air pollution control
equipment to reduce lead emissions. Studies by the
Lewis and Clark County Health Department found that
the number of children with elevated blood-lead levels
had declined. Thus in 1984, EPA listed the site on
the National Priorities List (NPL) which meant it was
authorized to receive long-term remedial response actions
under the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA), commonly
known as Superfund.

EPA enforcement staff negotiated a CERCLA
administrative order on consent requiring ASARCO
to complete a cleanup investigation, also known as a
remedial investigation. The remedial investigation found
that inorganic contaminants from on-site process ponds
and fluids had contaminated soils, plants, livestock,
surface water, sediment, and groundwater. Because of
the expansive and varied impacts, EPA divided the site
into five areas, or operable units (OUs), for cleanup. EPA
developed a cleanup plan for these focus areas with
different and overlapping timeframes:

•	OU1 - Process ponds and fluids

•	OU2 - Site-wide groundwater

•	OU3 - Surface soils, surface water, vegetation,
livestock, fish and wildlife, and air

•	0U4 - Slag pile

•	OU5 - Ore storage area

EPA enforcement played a critical role throughout the
various response actions, negotiating several CERCLA
administrative orders on consent and consent decrees so
that the investigations and response actions could move
forward. In turn, these documents required extensive
coordination with multiple parties, including the state and
ASARCO. The sections below describe enforcement efforts.

The remedial investigation of OUs 2-5 found that
contamination was greatest near the smelter, including
Prickly Pear Creek. These exposure risks - combined with
elevated blood-lead levels in children - prompted a swift
response. EPA and ASARCO signed an administrative
order on consent to quickly address lead- and arsenic-
contaminated soil in residential areas. Using this
administrative order on consent as a roadmap for soil
removal actions, ASARCO removed contaminated soil at
1,576 residential properties.

In 1998, EPA enforcement identified violations of
RCRA and the Clean Water Act (CWA) at the ASARCO
operating facility. Because the ASARCO facility was
still operating, RCRA became responsible for all OUs
except OU2, including the process ponds, slag pile
and ore storage areas on the smelter property. EPA
coordinated with the U.S. Department of Justice on
a RCRA consent decree; it transferred the remaining
cleanup of OU1, OU3, OU4 and OU5 and addressing of
site-wide groundwater contamination from the CERCLA
program to the RCRA program. The 1998 RCRA consent
decree required ASARCO to resolve the major remaining
environmental compliance issues.

Administrative Order on Consent

A voluntary and enforceable agreement under
CERCLA or RCRA, signed by EPA and private parties,
where the private parties agree to perform and/or pay
for some or all of the site cleanup costs.

Consent Decree

Judicial agreement between EPA and the PRPs
fully or partially settling a claim under CERCLA. This
agreement may settle litigation or may be presented
concurrently with the complaint (achieved through
negotiations). The agreement may be for response
work, cost recovery, or both.

A
CERCLA

Congress passed CERCLA, commonly known as Superfund, in 1980. EPA's Superfund program is responsible for
cleaning up some of the nation's most contaminated land and responding to environmental emergencies, oil spills,
and natural disasters. CERCLA establishes a comprehensive liability scheme to require certain categories of parties
to conduct or pay for cleanup of these lands. These parties include owners, operators, generators, transporters, and
others involved in the disposal of hazardous substances as defined by CERCLA. CERCLA's liability scheme ensures
that wherever possible, PRPs, rather than taxpayers, clean up the contamination they caused (often referred to as
the "polluter pays principle"). The polluter pays principle, combined with enforcement first, allows EPA to implement
CERCLA to achieve long term health and environmental benefits for communities.

RCRA

Congress enacted RCRA in 1976. RCRA, an amendment to the Solid Waste Disposal Act, was designed to address
the huge volumes of municipal and industrial waste generated by operating facilities. This includes hazardous waste
generated and disposed of by owners and operators who contaminate land, water, and air. Under RCRA, owners and
operators are liable for the cleanup of the contamination. RCRA protects human health and the environment in two ways:

1.	Prevention - Preventing future environmental problems from being caused by waste.

2.	Corrective Action - Cleaning up current environmental problems caused by the mismanagement of waste.
RCRA Corrective Action usually takes place at facilities that treat, store, or dispose of hazardous waste
and can be required through a RCRA order or permit. Corrective action can also take place while a facility
continues operation and it may be required through a RCRA permit, voluntary agreement, order, or
administrative or judicial action.

Late 1990s-2016
Cleaning up Operable Unit 2

Coordination among site stakeholders and the
dedicated work of EPA's technical and enforcement
teams resulted in agreements and consent decrees
that established cleanup actions and responsibilities
across most of the site.

EPA's site attorney and project manager worked
together on developing and drafting the OU2 remedy. It
established final soil cleanup levels for residential areas
as well as cleanup levels for several other types of land
uses. It also established guidelines for potential future
development activities. Cleanup activities addressed a
residential yard, 23 unpaved road aprons, and seven
flood-channel sections.

TheOU2 remedy also requiredthecontinuationoftheLead
Education and Assistance Program (LEAP), administered
by Lewis and Clark County's Health Department, to
help ensure the protection of public health. LEAP was
established in 1996 under a modification of the 1991
administrative order on consent. In 1995, EPA and

Highlighting Proactive Partnerships: EPA and
Local Government

At East Helena, a strong federal and local government
partnership has contributed to the project's success.
EPA and East Helena officials, as well as Lewis and
Clark County representatives, meet regularly to discuss
the site. These partners proactively provide site status
updates and weigh in on decisions to move cleanup
efforts forward. Programs such as LEAP (see box
below) have been effective because of coordination on
multiple levels, such as joint efforts by the local school
superintendent and EPA site staff.

LEAP

The Lead Education and Assistance Program (LEAP)
helps residents living near the site prevent health risks
associated with exposure to lead. LEAP is an EPA-
funded and county-run program. The program offers
blood-lead screening for children and other services
to reduce long-term reduction of exposures to lead. To

ASARCO agreed to establish and fund LEAP. Since that
time, the program's local health professionals have led
efforts to educate the community and advise EPA and
ASARCO on how to protect the children of East Helena
from iead. The program developed into one of the most
effective education and abatement programs in the
United States. Blood-lead level screening, education
and guidance about rescreening is continuously
available through LEAP. The program also implements
institutional controls to reduce long-term exposure risks,
oversees soil handling activities, and works with response
contractors to make sure children are not living at or
routinely visiting properties with known contamination.
LEAP plans to host a screening event in 2017 to verify
that blood-lead levels continue to decrease.

Pursuing Settlement Solutions

When ASARCO filed for Chapter 11 bankruptcy, EPA's
Office of Site Remediation Enforcement participated
in a collaborative effort to address the company's sites
across the nation, including four former facilities in
Montana. A bankruptcy court approved the consent
decree and settlement agreement regarding the Montana
sites. The settlement agreement provided for transfer of
the former ASARCO properties to a custodial trust, to
be administered by a custodial trustee. The Montana
Environmental Trust Group (METG), as Custodial
Trustee for the Montana Environmental Custodial Trust,
assumed ownership of former ASARCO properties and
responsibility for cleanup, including the East Helena
site. The ASARCO bankruptcy settlement provided
Superfund and RCRA with funding for the site's cleanup
and long-term stewardship, and established a viable
ownership entity that manages and maintains former
facility properties and works with the community to
identify reuse opportunities for undeveloped ASARCO-
owned land.

EPA's National Bankruptcy Practice

EPA works diligently to ensure that ail appropriate
claims are brought before the bankruptcy
courts with respect to debtors who are liable
for contamination at sites of federal interest.
EPA's bankruptcy practice reflects the Agency's
commitment to pursue all sources of funds to
ensure that responsible parties, and not taxpayers,
pay for cleanup of hazardous waste.

ASARCO completed most of the cleanup components of
theOUl remedy prior to the 1998 RCRA consent decree.
To fulfill the remaining requirements of the consent
decree, METG is performing additional investigations,
implementing interim measures, and undertaking long-
term corrective action at remaining source areas on the
former smelter property. In addition, METG is sampling
groundwater emanating from the property to meet RCRA
investigation, reporting, and cleanup requirements.

Integrating Cleanup and Reuse

EPA worked with the City and a stakeholder group
representing Lewis and Clark County and regional
partners to identify potential future usesfor undeveloped
former ASARCO-owned land and portions of the
smelter facility.

The process identified several potential future uses to
help inform remedial and development activities:

1.	Prickly Pear Creek restoration and greenway
improvement, including restoration of riparian
corridors and adding trails and trailhead parking.

2.	A rail-accessible industrial park at the East Fields.

3.	Mixed-use commercial devepment in open
space areas north of Route 12.

4.	Cultural heritage tourism options that integrate
signage, exhibits, trails and future development
areas celebrating East Helena's smelting and labor
history.

Site stakeholders have been working to make these
plans a reality, in 2015, restoration and realignment
work began on Prickly Pear Creek.

Finalizing Remaining Cleanup

EPA's regional enforcement staff signed a CERCLA
consent decree with Chemet, the company that operates
a facility next to the smelter property, to perform cleanup
activities to address lead and arsenic contamination
on its property. The agreement required Chemet to
characterize the contaminants and clean up the area to
meet 0U2 cleanup goals.

Under RCRA, EPA currently oversees METG's cleanup
of the former smelting site, restoring the Prickly Pear
Creek stream channel and covering the consolidated
contaminated soils and materials to protect groundwater.

Planning for the Future

RCRA corrective action for remaining contaminant
sources is ongoing; when complete, the former smelter
facility will be restored for potential future uses.
Surrounding land uses include agricultural and open
space areas as well as residential, recreational and
commercial uses. Thanks to the comprehensive cleanup
efforts pursuant to EPA enforcement settlements with
the PRP and custodial trust, cleaned-up properties -
both undeveloped and agricultural - will be available to
support much-needed development. Community priorities
include new subdivisions, commercial districts, rail-ready
industrial parks, and recreation-and heritage-based uses.

Enforcement Makes a Difference

EPA's environmental enforcement program has helped
make a difference in thousands of communities
impacted by hazardous waste contamination. At sites
such as the East Helena site, the program ensures safe
and timely cleanups and pursues viable liable parties for
the performance and funding of those efforts. In East
Helena, Montana, EPA enforcement made the PRPs
accountable for contamination and required them to fund
the site's cleanup through a nationwide settlement with
ASARCO, and worked with site stakeholders to identify
potential future uses for undeveloped portions of the
former smelter facility. EPA enforcement will continue
to work with community members, local organizations,
remaining PRPs, the custodial trust and other oversight
agencies to keep the public informed and ensure the
cleanup's long-term protectiveness.
