Cleanup Enforcement in Action:

Cleanup and Redevelopment Support
Economic Success for a Community
in North Kansas City, Missouri

The Value of Environmental Enforcement

At the Armour Road Superfund site, the U.S. Environmental Protection
Agency (EPA), the city of North Kansas City (City) and potentially
responsible parties (PRPs) used enforcement tools to identify and
conduct cleanup activity that will address community priorities and
facilitate safe redevelopment of the site. This case study illustrates
how the Superfund enforcement program works collaboratively with
responsible parties, state and local governments, and stakeholders
to the benefit of the community.

Early and ongoing communication between the EPA Region 7
Superfund enforcement program (serving Iowa, Kansas, Missouri,
and Nebraska) and the PRPs resulted in an agreement that expedited
cleanup work at the site and a faster return to beneficial use of the
property. Along with the agreement, the EPA used comfort letters to
address the liability concerns of nearby businesses and prospective
developers. The EPA has remained involved throughout the site
cleanup process and supports continued beneficial reuse.

Today, the site is already providing economic benefits for the North
Kansas City community, even as the team continues planning
efforts for groundwater cleanup. On-site businesses now provide
benefits to the City and surrounding community by creating dining
options, health services, local employment opportunities, and tax
revenue. The redevelopment and resulting influx of commercial and
healthcare services have created a viable, sustainable commercial
corridor. Additional development is planned for the future.

Environmental Enforcement
Benefits the Community

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

"The Armour Road site is a prime example of what is possible when federal
S9 and local governments collaborate with private parties in the interest of both
environmental cleanup and economic development."

The site's location in North Kansas City, Missouri.

Facility operations resulted in soil and groundwater
contamination. An environmental assessment
conducted in 1989 identified arsenic contamination,
which prompted the Missouri Department of Natural
Resources (MDNR) to investigate site conditions.
Companies that owned the facility from the 1920's to
1986 include: Reade Manufacturing (1920s - 1968),
which later leased the facility to U.S. Borax (1963 -
1968), which was purchased and operated by Home
and Boatright Company (HABCO) (1968 - 1986),
which formed an entity called KC 1986 to sell the
property in 1986. KC 1986 later sold the property to
North Kansas City.

Facility Overview

North Kansas City, Missouri, is home to over 4,000
people. It is located just north of downtown Kansas
City, across the Missouri River. The 1.8-acre Armour
Road site property sits at the gateway to North Kansas
City, just northwest of a railroad and near Interstate 29.
From the 1920's to 1986, various companies made and
blended herbicides that were used by multiple railroad
companies to control vegetation along railroad tracks.

1989 - 2006

Site Characterization and Early Removal Actions

Based on four years of investigations (1989 - 1993),
confirming high levels of arsenic in the soil, in April 1996,
MDNR referred the site to the EPA's regional office. One
month later, the EPA took emergency action to place a
geotextile membrane - a liner to prevent the spread of
contamination - over the contaminated soil and fenced
the property. In December 1996, an administrative order
on consent for an engineering evaluation/cost analysis
(EE/CA) was entered between EPA and US Borax. The
EPA listed the Armour Road site on the Superfund
program's National Priorities List (NPL) in May 1999.

The EE/CA was completed in February 2002. After the
EE/CA, U.S. Borax led the removal actions to address

Comfort Letters/Status Letters

A comfort/status letter is intended to address
liability concerns at a site by providing information
about the cleanup status and likelihood of the
EPA's involvement at a site. Comfort/status letters
may address the following:

•	Status of the site;

•	Future anticipated actions at the site;

•	Available liability protections;

•	Reasonable steps to stop any on-going
releases and prevent future releases; and

•	The status of any EPA liens.

short-term cleanup priorities in two separate phases.
Phase 1 removed the building and foundation to an off-
site permitted landfill for disposal from August 2004
to October 2004. Phase 2 excavated and disposed of
contaminated soil beneath the site property from March
2005 to April 2006. Excavated soil was treated and
transported to an off-site permitted landfill for disposal.

North Kansas City acquired the property at auction
in 2004. With growing development interest in areas
around the site and the property's ideal location in the
community, the City prioritized its support for the site's
cleanup and redevelopment. To assist the City's cleanup
and reuse planning the EPA provided a comfort letter.

Throughout the cleanup and redevelopment planning
process, the EPA provided comfort letters to other
potential developers, neighboring businesses, and other
site stakeholders to help them make informed decisions
regarding the property's cleanup status and Superfund's
liability protections. The comfort letters helped facilitate
redevelopment. A restaurant and orthopedic office
now operate on the once-vacant site and are catalysts
for commercial and residential redevelopment in the
surrounding area as well.

2009 - 2017

An Innovative Approach to Long-Term Cleanup

For the site's ongoing cleanup, the EPA and U.S. Borax
entered into a consent decree to conduct a remedial
investigation/feasibility study in 2009. During the
investigation period, Rio Tinto, an international mining
company, acquired U.S. Borax in the 1960's and became
the parent company of U.S. Borax. U.S. Borax continues
to operate today as a wholly owned subsidiary of Rio
Tinto, while Rio Tinto is now the responding party to the
consent decree, following corporate reorganization with
Rio Tinto.

Supporting efforts to make sure cleanup work moved
forward to prepare the site for reuse, the EPA worked
with the PRPs and the City and discussed alternative
approaches to address the remaining site cleanup. In
2016, Rio Tinto began a voluntary soil response action
at other portions of the site with EPA oversight and the
Agency paused the feasibility study. After the voluntary
soil response action (soil excavation) was completed in
January 2017, the EPA continued with the feasibility
study to evaluate the site's contamination. The feasibility
study is ongoing.

2015-2019

Working Together to Facilitate Redevelopment

Before and during cleanup, the EPA and Rio Tinto worked
closely with the City to coordinate cleanup planning
and activities with commercial redevelopment plans.
Before returning the site to reuse, Rio Tinto worked with
the City to install a new utility infrastructure for future
development. Rio Tinto then completed the voluntary
response action. This coordination literally laid the
groundwork for redevelopment opportunities at the site.

To support future development of a sustainable and
viable commercial area, the EPA's regional office site
team worked with Rio Tinto and the Missouri Department
of Transportation (MDOT) to construct a temporary
access road across the site property. The temporary
access road was converted to an entryway for the main
road through the redevelopment project and represents
a collaborative process among the EPA's site team, the
City, the MDOT, MDNR, responsible parties, and other
stakeholders.

Redevelopment Success and the
L.E.A.F.S. Award

In September 2019, the EPA Region 7 office presented
its Leading Environmentalism and Forwarding
Sustainability (L.E.A.F.S.) Award to the City and Rio Tinto
in recognition of responsible reuse through innovative
thinking, sustainable practices, and environmental
stewardship. The EPA Region also recognized MDNR for
its partnership and involvement at the site.

Enforcement Makes a Difference

EPA's enforcement program has helped make a
difference in thousands of communities impacted by
hazardous waste contamination. At sites such as the
Armour Road site, the enforcement program helps
ensure responsible parties perform and pay for prompt
and protective cleanups and facilitate revitalization
through the use of enforcement tools. Significant and
sustained cooperation and communication among the
EPA, state agencies, responsible parties, and the City
enabled timely site cleanup and early consideration of
redevelopment possibilities that laid a strong foundation
for future growth at and near the site.
