Reference: MONITORING WELL ABANDONMENT
FORMER UNION CARBIDE CORPORATION PROPERTY
5400 HOVIS ROAD
CHARLOTTE, MECKLENBURG COUNTY, NORTH CAROLINA
BROWNFIELDS PROJECT #14040-10-60

Dear Ms. Young:

On behalf of CSX Transportation, Inc. (CSXT), Amec Foster Wheeler Environment &
Infrastructure, Inc. (Amec Foster Wheeler) is requesting approval from the North Carolina
Brownfields Program (NCBP) to decommission monitoring wells located on the Former Union
Carbide Corporation Property (Site) in Charlotte, North Carolina.

BACKGROUND

The Site, also known as the former Union Carbide Battery Recycling Site, is located at 5400 Hovis
Road, which is an industrial area of Charlotte, Mecklenburg County, North Carolina. The Site
previously contained a complex of nine manufacturing, office, and warehouse buildings. The Site
comprises approximately 17.65 acres with 2.4 acres being a battery waste disposal area (BWDA).
The BWDA was classified by the North Carolina Department of Environment Quality (NCDEQ),
Division of Waste Management (DWM), Inactive Hazardous Sites Branch (IHSB) as an inactive
hazardous waste disposal site. Chlorinated solvents and metals have primarily been detected in
the Brownfields Property’s groundwater, and Polycyclic Aromatic Hydrocarbons (PAHs) and
metals have been documented in the soil. In 2012, all buildings were razed and infrastructure was
removed from the Site, with the exception of some concrete building foundations and pads.

In August 2012, the Site entered into a Brownfields Agreement (BFA) issued by the NCDEQ,
DWM, Brownfields Section (Brownfields Section). When the BFA was issued, CSXT purchased
the Site and planned to develop a parking and storage facility to expand its railroad operations
adjacent to the Site. An Environmental Management Plan (EMP) was also submitted and
approved by the NCBP on November 13, 2013, which outlined the management of impacted
media during redevelopment activities at the Site. The development plans have since been

stalled and the Site is currently being used to store overflow equipment, specifically, parking of
motor vehicles and storage containers. The temporary use of the Site for parking and equipment
storage was discussed and approved with the NCBP. However, since the BFA was issued, the
Site has not undergone any physical redevelopment or construction activities. Additionally, the
soils on the Property have not been disturbed.

There are currently 10 monitoring wells at the Site (Figure 1). There are currently no groundwater
monitoring requirements for the site with the last groundwater monitoring event occurring in 2011.
On behalf of CSXT, Amec Foster Wheeler requests approval for decommissioning the 10 wells
located at the Site. As part of the well decommissioning activities, Amec Foster Wheeler will
abandon the monitoring wells as follows:

• Removal of concrete pads and bollards;
• Abandonment of the 10 monitoring wells by a licensed well driller;
• Surface restoration following removal of concrete; and
• Reporting to NCDEQ.

Following the abandonment of the monitoring wells, Amec Foster Wheeler will submit a letter
report to NCDEQ upon receipt of the well abandonment records documenting the well
abandonment activities.

Please review the attached information. If you have any comments or questions, please contact
Bonani Langan at [phone] or via email at [e-mail].

Sincerely,

Amec Foster Wheeler Environment & Infrastructure, Inc.
