1.0 Introduction
On October 16, 2014 a team of 13 environmental health and safety (EHS) professionals in
training, and Dr. Heather Wilkinson, Professor at Texas A & M University (TAMU) visited the
petroleum storage and pumping facility located within the Transportation Center at TAMU. The
Environmental Safety Specialist for the EHS department at TAMU, Ms. Toni Eubanks, provided a
descriptive tour of the facility and addressed all the questions the team raised. Ms. Eubanks also
led an informational discussion of the Texas A & M University Phase II Municipal Separate Storm
Sewer System. This report details the site visit with an emphasis on features associated with EHS
compliance
2.0 Features of the Site
2.1 The Transportation Center is located at 388 Agronomy Road, College Station, TX 77845.
2.2 The facility serves as the only refueling, maintenance, and repair center in College Station
for the 556 vehicles owned and operated by TAMU. The facility pumps an average of
1000 gallons per day of unleaded gasoline, 650 gallons per day of diesel, and 750 gallons
per day of B20 Biodiesel.1 The facility utilizes three 12,000 gallon capacity underground
storage tanks (UST’s) to maintain fuel inventory. The Transportation Center also
maintains inventories of oil, in varying size containers, on campus although those were
not toured during this site visit and are therefore not included in this report.
2.3 TAMU meets the Financial Assurance requirements set forward by the United States
Environmental Protection Agency2 by maintaining a Liability Account. The Liability
Account maintains two separate limits; one to cover the cost of “one daily occurrence”
and one to cover “the cost of all UST releases that might happen in one year.1
3.0 Relevant State and Federal Regulations
3.1 The facility maintains a Spill Prevention, Control, and Countermeasure Plan (SPCC),
required by the EPA and enforced by the Texas Commission on Environmental
Quality (TCEQ). This plan is designed to prevent any discharge of oil into navigable waters
or adjoining shorelines.2

3.2 All UST’s must be registered with TCEQ within 30 days of installation. All operators of the
UST’s must complete initial safe operation training and retraining every three years. There
are three classes of Operator Permits; Class A Operators have the primary responsibility for
the UST facility, Class B Operators are responsible for the day to day operation at the
facility, and Class C Operators control the dispensing operations. All UST’s are required to
be installed by licensed installers only and supervisors must be on site during the
installation process.
3.3 All UST’s must have corrosion protection, release detection, spill and overfill prevention,
and Stage I & II Vapor Recovery systems. Corrosion protection is provided by the use of
Sacrificial anodes placed inside of the UST’s, and the use of non-corrodible materials in the
manufacture of the UST’s. The anodes must be tested 3-6 months after install and every 3
years after that. TAMU utilizes an automatic tank gauging and inventory control system
(Figure 1) as the primary, and a manual measure and record system as the secondary means
of leak detection. Various spill and overfill prevention measures used at the facility are
found at the fueling center (Figure 2). These include spill containment equipment; cat litter
for small spills, and berms for larger spills. There are emergency shut off valves (Figure 3),
quick release hose fittings, audible and visual alarms, as well as warning/caution signage.
(Figure 4). Stage I & II Vapor Recovery Systems capture vapors that escape during fuel
transfers. Stage I captures vapors released during fuel delivery into UST’s and Stage II
captures vapors released during refueling of vehicles.
3.4 Any leak that occurs in excess of 25 gallons or results in a sheen on surface water must be
reported to TCEQ within 24 hours of occurrence. A corrective action plan must also
accompany the report of a spill.
4.0 Phase II Municipal Separate Storm Sewer System
4.1 TAMU operates a Municipal Separate Storm Sewer System (MS4 ) that is comparable to a
small municipality. To maintain compliance TAMU participates in Municipal Control
Measures (MCM’s) designed to increase awareness of and decrease contributions to storm
water pollution. MCM 1 focuses on Public Education and Outreach and is facilitated through
community, employee, and student education of storm water pollution prevention techniques.
MCM 2 is based on Illicit Discharge Detection and Elimination. The EHS department at
TAMU conducts 2 official inspections per year of storm sewer outfalls and has a hotline
number the public can use to make notification of potential Illicit Discharges. MCM 3
PAGE 3
requires all Construction Contractors to “select, install, implement, and maintain stormwater
control measures that prevent illicit discharges.”1 MCM 4 pertains to post-construction storm
water management and encompasses new developments as well as redeveloped areas. MCM
5 pertains to Good Housekeeping practices that ultimately will prevent or reduce the amount
of pollution runoff from the TAMU campus.

Fig. 1 Gilbarco Automatic Tank Gauging and Inventory Control System. Provides constant fuel level
measurements and sounds an alarm when a leak in the UST is detected. This system is used in
conjunction with a manual read and log system for fuel inventory.
Fig. 2 Spill prevention equipment located directly on the fueling center. Supplies to
contain a spill (cat litter or a containment berm) are kept in a cabinet sitting directly
next to the fuel dispensing pumps.

spill to immediately discontinue the flow of fuel from the pumps.

Fig. 5 Stage I Vapor Recovery System. Vapors released during fuel delivery into UST’s are
captured and returned to the fuel delivery truck.
Fig. 6 Stage II Vapor Recovery System captures gasoline vapors when a vehicle is being fueled at
the pump. The vapors are returned through the pump hose to the petroleum storage tank
instead of being released into the air.
