Summary of Best Management Practices at the Permitted Facility
Best Management Practices
Hazardous Materials Facility (HMF)
The HMF is located south of Estes Drive Extension (see Figure 3). The HMF operates under a
Treatment, Storage and Disposal (TSD) permit pursuant to the Resource Conservation and Recovery Act
(RCRA) authorizing UNC-CH to treat, store and dispose of hazardous waste generated by UNC-CH and
UNC Health Care at this facility. Additionally, mixed radioactive wastes generated at UNC-CH are
picked up on campus and transferred to HMF for storage before being shipped off site for disposal. Best
Management Practices (BMPs) in place at the HMF include:
• The HMF has an automatic fire and smoke detection -alarm system and built-in closed floor sumps or
berms for spill and leak detection and collection.
• As required by the RCRA permit, all hazardous materials are stored inside of the buildings in closed,
labeled, waste -compatible containers. Inspections of the facility contents and equipment are
conducted on a daily and weekly frequency.
• The loading dock in front of the HMF is sloped towards the building and bermed to prevent runoff in
case of a spill, so that any spilled material will stay onsite and can be controlled, treated, cleaned up,
and properly handled. During any bulk liquid transfer activity, facility employees are present and
employ absorbent booms around the transfer points.
• The facility is totally secured with an 8-foot fence, is alarmed and is locked when not occupied.
• Regular good housekeeping practices are followed
• The facility employees are all trained annually according to OSHA HAZWOPER, EPA and DOT
regulations.
• Spill cleanup materials as required by the RCRA permit are on site.
University Service Station
The University Service Station is located off Airport Drive, behind the Giles Homey Building. The
Service Station functions as a gasoline station and garage for University and State vehicles. The service
station contains four service bays and one vehicle washing bay.
BMPs in place at the University Service Station include:
• The garage operates four inside bays for vehicle oil changes, inspections and minor repairs. Service
Station floors slope into the bays to keep spills within the bays. All maintenance activities are
performed in the bays.

• The wash bay has a three-phase collection and recycling system for wash water and a 1,500-gallon
oil -water separator to collect wastewater generated from the washing process. The separator is
connected to the sanitary sewer, which receives overflows from the recycle process. The separator is
inspected regularly for oil levels and oil is pumped out of the separator when a percentage of the total
oil storage capacity is reached.
• Storage of materials used in vehicle maintenance and cleaning processes is conducted inside of the
facility.
• New motor oil usage is approximately 100 gallons per month, and inventory is maintained at four or
fewer 55-gallon drums onsite at any one time. Outdoor storage of materials associated with the
service station includes new oil stored in drums within secondary containment and protected from
weather elements, tires within a covered trailer, recyclable metal within a drum and used lead acid
batteries stored within covered, secondary containment prior to removal from the site for recycling.
• Petroleum is stored in two underground storage tanks (USTs). The tanks include a 550 gallon used
oil tank and a 10,000 gallon gasoline tank. Both tanks are double -walled steel wrapped by fiberglass,
and the piping is doubled -walled flex piping. The leak detection system on each UST is a Veeder
Root TLS-350, which consists of interstitial monitoring of void spaces around the tank and piping and
daily automatic tank gauging. The gasoline system also features a Red Jacket automatic line leak
detector to detect leaks from the pressurized piping system, and each UST is fitted with spill and
overfill prevention equipment. The overfill prevention equipment restricts the flow of fuel into the
tank when it reaches 95% capacity, and an audible alarm is sounded.
A closed, gravity -feed system for used oil management is installed within the Service Station facility.
The system is used for transferring used oil the oil to the 550-gallon UST. The used oil is regularly
collected for recycling by a commercial oil company. Spills resulting from removal of oil from the
UST are contained and cleaned up with spill response materials stored outside on the north side of the
Service Station. These include a portable drain mat that can be placed over the catch basin inlet
proximal to the tank to prevent a release occurring during emptying of the tank.
• Used oil filter management. Used oil filters are punctured and hot drained for at least 24 hours, and
then oil disposed of into the used oil tank for recycling. The used oil filters are also recycled by a
commercial used oil recycling company.
E85 (ethanol) is stored in an aboveground storage tank (AST) equipped with secondary containment.
The tank is a 10,000 gallon storage tank located northwest of the Service Station. The tank is double -
walled steel and is supported on steel legs. The leak detection system consists of interstitial
monitoring of void spaces around the tank and visual tank gauging. The AST is equipped with spill
and overfill prevention equipment that provides a visual and audible alarm at 95% capacity. Spill
prevention equipment is provided for the E85 AST as a containment box that is designed to capture
small spills occurring during uncoupling of the refueling line to the tank. Additionally, spill
containment and cleanup materials are stored next to the tank to clean up spills occurring outside of
the containment and prevent the spills from entering the storm drain system.
• Spill response and clean up materials include 100 pounds of absorbent material and two 10-foot
absorbent booms stored in containers on the north side of the Service Station.

• Regular good housekeeping practices are followed.
• Employees are trained annually regarding preventative maintenance, good housekeeping and spill
response and clean up procedures.
• The faculty is inspected twice per year.
