Reuse and the Benefit to Community
Koppers Coke Superfund Site
Executive Summary
A legacy of contamination left vacant nearly 40 acres of valuable property in
Saint Paul, Minnesota. Once the site of a foundry coke production facility, the
property was located next to major industrial and commercial development and
transportation infrastructure, which spurred the Saint Paul Port Authority to
clean it up for redevelopment. As a result of the Port Authority's vision, part of
Energy Park, a thriving commercial development, now stands on the Koppers
Coke Superfund site. The site's characteristics, creative planning, and the
cooperation of public and private stakeholders contributed to this
redevelopment success story. Today, businesses at Energy Park employ over
3,800 people; businesses on the Koppers Coke site portion of the development
employ 1,667 people and contribute $1.6 million in local property taxes. This
case study explores the local economic revitalization resulting from the cleanup
and redevelopment of this Superfund site.
Positive Impacts
•	In 2012, the businesses on the Koppers Coke site portion of Energy Park employed 1,667 people
and provided an estimated $119 million in annual income to employees.
•	Properties on the Koppers Coke site portion of Energy Park generate over $1.6 million in annual
property tax revenues.
•	The project has exceeded the Saint Paul Port Authority's Board of Commissioners' project
requirements, which mandated one new or retained job per 1,000 square feet of new space. The
project currently provides 2.4 jobs per 1,000 square feet.

Introduction
Superfund site cleanup and reuse results in restored value to
site properties and surrounding communities. Once a site
property is ready for reuse, it can revitalize a local economy
with jobs, new businesses, tax revenues and local spending.
This case study describes the site's cleanup and captures the
on-site and community impacts of new development at the
Koppers Coke Superfund site.
Energy Park occupies 218 acres in Saint Paul, Minnesota; the
Koppers Coke site is a 40-acre part of the facility. Energy
Park is situated northwest of downtown Saint Paul, one mile
north of Interstate 94 and about three miles west of
Interstate 35 (Figure 2). According to 2010 Census data,
about 285,000 people live in Saint Paul.
Site History
For over 60 years, Koppers Industries, Inc. operated a coking facility on the site property, producing foundry
coke and various byproducts, including coal tars, creosote, oils and greases, and other wastes. Inadequate
storage and disposal practices and leaks and spills resulted in the contamination of soil and ground water. In
1978, Koppers Industries, Inc. and and the Minnesota Pollution Control Agency (MPCA) entered into an
agreement for the facility's demolition and an investigation of the subsurface; site assessment activities
characterized the nature of the contamination the following year. The coking facility was subsequently
demolished and 20 tanks and over 20,000 cubic yards of contaminated soil were removed for disposal.
Following additional site assessment activities performed by MPCA, EPA added the site to the Superfund
program's National Priorities List in 1983. The next year, MPCA added the site to Minnesota's Permanent List of
Priorities.
Site Cleanup and Renewal
During the early stages of site cleanup, development of adjacent parcels was underway as part of the mixed-use
Energy Park development. This project incorporates historic preservation of nineteenth century railroad
buildings, innovative energy efficient features and a district heating and cooling system, low-income housing,
and a new baseball stadium. This development and the Koppers Coke site's location near major roadways in the
center of an industrial/commercial area created a highly marketable setting, spurring the Saint Paul Port
Authority to realize the site's significant reuse potential. The Port Authority acquired the site property in 1982
for additional Energy Park development.
In support of its stated goal of improving the economic environment in Saint Paul and surrounding areas, the
Port Authority purchases and cleans up formerly contaminated sites to MPCA standards, mitigating
environmental hazards while creating new places to do business. According to the Port Authority, reusing
formerly developed sites helps keep businesses where their employees live, eases traffic congestion and heals
pockmarked areas of inactivity that can debilitate urban neighborhoods.

With grant assistance from the Minnesota Department of Employment and Economic Development (DEED) and
the Metropolitan Council (serving the greater Twin Cities region) and with guidance and oversight from MPCA,
the Port Authority worked to clean up the Superfund site and readied it for use. Cleanup activities included
removal of contaminated soil, contaminant source capping and installation of a bioremediation system for
ground water treatment. These activities were completed by 1998 and long-term monitoring began that year.
MPCA delisted the site from the state's Permanent List of Priorities in February 2003.
Phased Development
Redevelopment of the site took place in phases. The first building, which now houses the industrial automation
device distributor Power/mation, was finished in 1985, followed by two buildings on the west end of the site
that make up Energy Park Place. A 241,000-square-foot complex at the east end of the site was built in 1991 to
house Control Data Corp's ETA Systems, and subsequently expanded to 361,000 square feet in 2001 to
accommodate U.S. Bancorp, a commercial banking services provider.
By the early 2000s, the last undeveloped parcel at Energy Park was an 8-acre lot at the center of the Koppers
Coke site. To complete the site's cleanup and redevelopment, the Saint Paul Port Authority partnered with Ryan
Companies, a real estate development firm. This partnership coupled the Port Authority's decades of experience
in site cleanup and redevelopment with Ryan Companies' real estate marketing and development expertise.
Together, the organizations redeveloped the remaining 8-acre portion of the site into Energy Park Corporate
Center, a commercial center and high-tech industrial park.

In July 2003, Ryan Companies completed construction and
several businesses moved in. In total, Energy Park Corporate
Center provides 110,300 square feet of commercial office
space. The end result, as summed up by Minnesota DEED'S
Commissioner Matt Kramer, was that the "relatively modest
investment over time by the project partners produced a
healthier environment and an economically vital project that
will attract new jobs to Saint Paul and increase the city's tax
base."
According to Tom Collins, Director of Marketing and
Communications at the Port Authority, Energy Park Corporate
Center is the successful outcome of perhaps the first full
partnership between a public entity and a private developer
in the country. Representing a true collaborative effort, both
partners retain a 50 percent share in the ownership of the
property.
By teaming up to develop the site and build a series of
commercial complexes, the Port Authority and its partners
helped eliminate an environmental hazard that had become a
community blight. The completion of the five projects on the
Koppers Coke site transformed a vacant, polluted area into a
development that has improved the city's job and tax base,
while enhancing quality of life in the surrounding North End
neighborhood. Today, ground water monitoring is ongoing
and agency officials are working toward the site's official
delisting from EPA's National Priorities List.

Conclusion
In Saint Paul, Minnesota, local entities, state agencies and EPA came together to share resources, collaborate
and coordinate closely to clean up and redevelop the Koppers Coke Superfund site. These efforts resulted in
striking outcomes: the protection of human health and the environment and community revitalization. Today,
businesses on site provide 1,667 jobs, $119 million in estimated annual employee income and $1.6 million in
local property taxes. Looking to the future, the reuse of the Koppers Coke Superfund site as part of Energy Park
will continue to serve as an asset for the surrounding North End neighborhood and the City of Saint Paul. The
project is a compelling example of how environmental protection and beneficial site reuse can result from
dedicated stakeholders working together in innovative ways over the long term.
