2007 Demonstration Project
Macalloy Corporation:
North Charleston, South Carolina
THE SITE: The Macalloy Corporation site is situated in aprimarily industrialized
area of North Charleston, South Carolina. This former ferrochromium alloy
manufacturing plant fronts Shipyard Creek in a section of the Charleston
Peninsula referred to as "The Neck," which is formed by the confluence of the
Ashley and Cooper Rivers. In November 2006, the Macalloy site was recognized
by the U.S. Environmental Protection Agency (EPA) as the 1,000th National
Priorities List (NPL) site in the United States to achieve remedial construction
completion status. The cleanup activities required by EPA for continued industrial
site use included ex-situ soil mixing, groundwater treatment and monitoring,
sediment excavation, tidal creek restoration, and implementation of a storm
water management system. The accelerated cleanup, which lasted only six years
from NPL listing to construction completion, has expedited the Macalloy site's
transition from a contaminated and environmentally impaired piece of property
to a site put to beneficial reuse for the North Charleston community.
THE OPPORTUNITY: Charleston is currently experiencing exponential
growth, which is driving the need to creatively recycle land within the city
boundaries. In February 2005, the Macalloy property was purchased by Ashley
II of Charleston, LLC (Ashley II) while remedial action was underway. Ashley
II is a partnership consisting of Cherokee Investment Partners (Cherokee),
Greenhawk Partners, and local real estate interests. Ashley II plans to relocate
existing commercial and industrial businesses along the Ashley River corridor
to about 20 acres of the Macalloy parcel in late 2007. This move will open up
space for Ashley IPs planned Magnolia project that incorporates new urbanism
components (live/work/play environments). The remaining 120 acres of the
Macalloy site will likely be redeveloped as a port facility that utilizes the multi-
modal transportation routes of Interstate 26, CSX rail lines, and deep water in
adjacent Shipyard Creek. EPA's assistance is vital to ensuring that human health
and the environment remain protected throughout the cleanup and redevelopment
process.
THE BARRIERS: The success of the various stakeholders was dependent
upon establishing appropriate cleanup goals that were protective of human
health and the environment, while developing a remediation strategy that
would accommodate future use of the site as an industrial park. One of the
primary remedial action objectives at the Macalloy site was to mitigate offsite
contaminant discharges in storm water to the adjacent Shipyard Creek through
a combination of remediation measures and a comprehensive site-wide storm
water management plan. The selected storm water management system had to not
only mitigate offsite discharges of impacted storm water, but also accommodate
future site development plans.
Barriers:
Establishing appropriate protective
cleanup goals and a remediation
strategy that would accommodate
future industrial reuse
Solution:
EPA's ability to work with both
responsible parties and developers
to maximize resources and keep the
project moving forward
Before:
Former ferrochromium alloy
manufacturing plant located in a
highly industrialized area
After:
Macalloy Superfund site put to

THE SOLUTION: Cherokee and EPA demonstrated their steadfast commitment to the project by going above and beyond
to maintain communication between the many stakeholders. Negotiations are ongoing with EPA to upgrade the remedies
in some areas that will be protective for residential use as well. At the Macalloy site, EPA worked closely with Cherokee to
redesign the storm water management system in a way that would work with Macalloy's planned reuse. Redevelopment of
the Macalloy site in particular will maintain and create industrial jobs, which are important to the economic growth of the
community.
THE SITE NOW: Redevelopment efforts at the Macalloy Corporation site and surrounding properties in the Neck owned
by Cherokee represent the largest reclamation project attempted thus far by private developers in South Carolina. The
Macalloy site in particular now offers approximately 20 acres for potential industrial redevelopment. The remainder of the
Macalloy site will likely be reused as a port facility that takes advantage of existing multi-modal transportation infrastructure.
Relocation of industrial businesses onto the parcel is already underway and the first three industrial businesses began
operating on the Macalloy property in 2008. These include a paper recycler (Paper Stock), a liquid sea container storage
business (Boasso) and a tank cleaning business that cleans Boasso's containers (Phillips Services). Progress is also being
made at the nearby properties in support of the Magnolia and Ashley River Center developments, also owned by Cherokee.
At the Macalloy site, ground water and storm water monitoring are on-going and EPA monitors erosion of the surrounding
river banks.
