SITE MANANGEMENT PRACTICES AND SPILL RESPONSE
WILCO #191

YOUNGSVILLE, NORTH CAROLINA
Dear Mr. Klimek:
On behalf of WILCOHESS, LLC (Wilco), and as required in Section A.(2.) of their National
Pollutant Discharge Elimination System (NPDES) Permit No. NCO087912 for the above facility,
Mid -Atlantic Associates, Inc. (Mid -Atlantic) has prepared the following letter. The purpose of this
letter is to outline site management practices that will be conducted in an attempt to minimize
the amount and strength of wastewater generated at the diesel dispenser islands and
discharged from the treatment facility, as well as spill response procedures that will limit the
release of fuels from the Bite.
Site Management Practices:
The following site management practices are in place and/or will be conducted to minimize the
amount and strength of wastewater generated at the diesel fuel islands and discharged from the
treatment facility:
• The diesel dispenser islands are covered by a canopy;
• A frame and grate system, connected to a grit separator and oil/water separator, has
been installed at the site and is designed to limit stormwater flow into the system;
• Dry absorbents and spill kits are kept at the facility, according to Wilco personnel;
• Spills. and leaks from vehicle fueling operations are cleaned up upon detection using dry
absorbents;
• Dispensers are equipped with "break -away" hoses to prevent vehicles from driving off with
the fuel nozzle in the vehicle and rupturing the fuel hose while the pump is running;
• The diesel dispenser islands will be inspected during visits by the designated Operator -
in -Responsible -Charge (ORC) or backup ORC;
• The collection system and oil/water separator will be inspected during visits by the ORC
or back-up ORC; -
• The collection system and oil/water separator will be maintained in general accordance
with manufactbrer's recommendations; and --

• The oil/water separator will be pumped out periodically to insure there is adequate
capacity in the unit.
SiDN Response Procedures
The following spill response procedures will be conducted in order to limit the release of fuels
from the site:
• Minor spills and leaks from vehicle fueling operations will be cleaned up immediately upon
detection using dry absorbents;
• The source of the spill will be closed off, shut down and/or disconnected;
• In the event that the volume or flow rate of the spill causes it to by-pass the frame and
grate system, immediate control and clean-up will be initiated to prevent the spread of the
petroleum and prevent and/or minimize surface water contamination. The topographically
downgradient storm drain, located in the southeastern comer of the site, will be isolated to
prevent petroleum from entering the drain. Spill booms, "pigs", absorbent pillows and/or oil
dry dams will be used to confine the spill and isolate it from the storm drain or other
conduits of travel;
The Wilco employee will contact the Emergency Coordinator and the ORC or back-up
ORC. The Emergency Coordinator will be responsible for contacting the appropriate
response personnel and the ORC or back-up ORC will be responsible for reporting the
release to the appropriate governmental agencies. A table of Emergency Spill Response
Numbers is enclosed.

We hope this information satisfies the requirements of Section A.(2.) of Wilco's NPDES Permit
for the above facility. If you have any questions or need additional information, please feel free
to contact us at 250-9918.
