1.
During an inspection and service visit at a California underground
storage tank facility, a service technician is asked to evaluate equipment
associated with a regulated petroleum UST system. The technician must
perform the work in accordance with applicable California UST
requirements while also ensuring that the equipment remains capable of
detecting releases and maintaining the integrity of the system. Before
beginning the service work, which action is most appropriate?
A. Immediately disconnect all monitoring equipment so that the
technician can inspect the components without interference
B. Review the applicable facility records, system configuration, previous
service documentation, and relevant manufacturer requirements before
performing the work
C. Replace every monitoring component regardless of its operating
condition to ensure compliance
D. Disable the automatic monitoring system permanently while the
technician completes the inspection
Answer: B
2.
A California UST facility uses an automatic tank gauging system to
monitor underground storage tanks and assist in detecting possible
releases. During a routine service visit, the technician discovers that the
,2
ATG console is displaying an alarm associated with the tank monitoring
system. The facility operator asks the technician to simply acknowledge
and clear the alarm so that normal operations can resume. What should
the technician do?
A. Clear the alarm immediately because an alarm does not necessarily
indicate a release
B. Disconnect the console until the operator can investigate the issue
C. Determine the cause of the alarm and perform the appropriate
diagnostic evaluation before returning the system to normal operation
D. Ignore the alarm if the tank contains less than half of its normal
operating capacity
Answer: C
3.
A service technician is working on an underground storage tank system
equipped with electronic monitoring equipment. Before opening or
servicing electrical components located in a potentially hazardous area,
the technician must consider the possibility that flammable vapors may
be present. Which approach is most appropriate when performing
electrical service work on UST equipment?
A. Use any electrical equipment that is available as long as the work
takes less than 30 minutes
B. Follow applicable hazardous-location requirements, manufacturer
instructions, and appropriate electrical safety procedures
C. Use extension cords from a nearby building because underground
tank areas are normally ventilated
D. Disable only the facility lighting before opening the electrical
enclosure
Answer: B

A technician is called to a facility because the automatic tank gauge
repeatedly reports an unexpected increase or decrease in product level
even though the facility operator states that no fuel deliveries or
dispensing activities occurred during the period. The technician reviews
the gauge history and notices several irregular readings. Which potential
condition should receive appropriate consideration during
troubleshooting?
A. A possible measurement problem, equipment malfunction, or release
condition
B. Normal operation that requires no further investigation
C. A condition that can be eliminated simply by resetting the gauge
D. A problem limited exclusively to the dispenser filters
Answer: A
5.
During service of a UST monitoring system, a technician determines that
a sensor is producing readings outside the expected operating range. The
manufacturer specifies a particular testing and calibration procedure for
the sensor. Which action is most appropriate?
A. Modify the manufacturer's procedure because every UST sensor uses
the same calibration method
B. Replace the sensor immediately without performing any diagnostic
testing
C. Follow the applicable manufacturer's instructions and required testing
procedures when evaluating and servicing the sensor
D. Adjust the sensor until the reading appears reasonable without
documenting the adjustment
Answer: C

A UST facility has multiple tanks containing petroleum products, and
the technician is asked to service the tank monitoring equipment. The
technician notices that the monitoring console identifies each tank using
a specific tank number and product designation. Why is correctly
identifying the tank and associated monitoring device important before
performing service?
A. It allows the technician to bypass required monitoring procedures
B. It helps ensure that testing, maintenance, and documentation are
associated with the correct tank and equipment
C. It eliminates the need to review facility records
D. It allows any sensor to be installed in any tank without verification
Answer: B
7.
A technician is troubleshooting a liquid sensor installed in a sump that
forms part of a UST release detection system. The monitoring console
indicates a liquid alarm, but the facility operator believes the alarm is
false because no fuel release has been observed. What should the
technician do first?
A. Permanently disable the sensor
B. Investigate the sump and sensor condition and determine the source
of the alarm
C. Replace the monitoring console without testing the sensor
D. Clear the alarm and instruct the operator to ignore future alarms
Answer: B
8.

designed to detect liquid between the primary and secondary
containment layers. During routine service, the technician observes
