The UC Irvine Underground Storage Tank (UST) Program provides
guidance to the campus in UST management as well as surface and ground
water pollution prevention. The program also provides compliance guidance
on State Water Resources Control Board (SWRCB) and other UST laws and
This program applies to all entities within the UC Irvine campus including
North Campus and University Research Park. The This program details the
elements that are required of the UST Program in order for the campus
to maintain compliance with all Federal, State and Local UST regulations.
This document is to provide guidance to UST operators (i.e. Central
Plant) responsible for maintaining tank systems in compliance with Federal,
State and Local regulations.
5.1.1 Written Monitoring Procedures: Written leak
detection monitoring procedures must exist and include:
of the leak detection monitoring; and
equipment used to perform the leak detection monitoring -
Storage Tank Monitoring Plan.
5.1.2 Written Monitoring Records: All leak detection
monitoring records are maintained on site, including but not limited
Maintenance records for the last 3 years (including
periodic equipment calibration);
Monitoring System Inspection Form -Inspection log verifying that the leak detection
system has power and is NOT in alarm;
Alarm printouts (for electronic
leak detection equipment);
Groundwater or vapor well
sampling records (if applicable);
Location of monitoring probes and control (alarm)
5.1.3 Written Emergency Response Plan: The written
emergency response plan outlined in the Hazardous Materials Business
Plan (HMBP) includes:
Contact information for equipment service or to investigate
alarm conditions; and
Procedures for notifying the
local fire/hazardous materials agency.
5.2 UST - Hazardous Material Dispensing Units
5.2.1 Hoses and Nozzles: Hoses are not crimped or collapsed.
Nozzles are product-tight.
5.2.2 Leaks/Weeping Joints: Pipes are not leaking.
Joints are not weeping.
5.2.3 Containment: The containment and/or area under
the dispensers must be kept dry at all times. Fuel filters are carefully
removed to avoid spillage into the containment and/or area under the
5.2.4 Fittings/Hose Connectors: Fittings and hose connectors
are not disconnected.
5.2.5 Electrical: Electrical wires are not exposed
(i.e. no open conduit).
5.2.6 Shear Valves: Shear valves must be installed
under dispensers to stop product flow resulting from an accident that
damages the dispenser. These valves must be inspected periodically to
verify that they are functional.
5.3 Underground Tanks/Piping
5.3.1 Overspill Containment: Each tank fill opening
must be equipped with an overspill container of at least a five (5) gallon
capacity. The container is connected to the tank via a plunger or drain.
The container must be maintained in a dry condition at all times.
5.3.2 Overfill Prevention: To prevent tank overflow
during product delivery, each tank must be equipped with either:
A mechanical "flapper-valve" tube which
is inserted inside the product fill tube
An electronic sensor that alarms when delivered product
reaches 95% of the tank capacity.
5.3.3 Manway Sumps: All manway sumps must be maintained
in a dry condition. Leakage must not occur from pipeline detectors or
other equipment located inside the sumps. In addition, sumps containing
liquid sensors must be located at the bottom of the sumps.
5.4 Leak Detection Equipment
Detection System: An approved leak
detection monitoring system or program must be installed and functioning
Inspections: All leak detection
equipment must be visually inspected on a monthly basis to verify
There is power to the equipment; and
equipment is NOT in alarm.
5.4.3 Calibration: All leak detection equipment (including
pipeline leak detectors) must be tested and calibrated at least annually.
5.5 Designated UST Operator
5.5.1 Effective January 1, 2005, UCI will assign a Designated UST
Operator who has passed the operator exam administered by the International
Code Council. A certified contractor may be utilized to fulfill this
5.5.2 Effective July 1, 2005, and annually thereafter, the Designated UST
Operator will train facility employees in the proper operation and maintenance
of the UST system.
5.5.3 UCI employees hired on or after July 1, 2005, must complete
initial training within 30 days of the hire date.
5.5.1 Emergency Shut-off Switch: A master Emergency
Shut-Off Switch must be located in an accessible area within sight
of all dispensers. This switch must be labeled and maintained in working
condition at all times.
5.5.2 Fire Extinguishers: Fire extinguishers with a
minimum rating of 2-A:20-B:C must be located in accessible areas no further
than 50 feet from pumps and dispensers. It is the responsibility of the
tank operator to ensure all extinguishers have been serviced within the
last 12 months (verifiable via service tag).
5.5.3 Cathodic Protection: For steel tank systems,
a cathodic protection system must be installed to protect tank(s)/piping
from rusting and deterioration. The tank operator must inspect the
system once every three months.
5.5.4 Secondary Containment Testing: All secondary
containment systems installed prior to January 1, 2001 must have secondary
containment testing every 36 months by a certified UST testing contactor.
5.5.5 Signs: The following signs must be posted next
to the UST's:
Into Unapproved Containers Is Prohibited"
Stop During Fueling Operations"
IN CASE OF FIRE OR SPILL
1. Use emergency pump shutoff!
2. Report the accident!
