PMIS 257302A / Above Ground Fuel Storage Tank Project Dinosaur National Monument

PMIS 257302

1.0 Overview

The existing above ground storage tanks fuel storage tanks (ASTs) are double walled tanks. There are three tanks total, two 2,000-gallon unleaded fuel tanks and one 2,000-gallon diesel tank. The two unleaded tanks serve two dispensers in the middle of the maintenance area connected by underground piping. The diesel tank has its own on-tank fuel dispenser. The fuel system components are well past their design life and failures are occurring. Replacement parts are not available due to the age of the system. Failure of any of the three pumps will result in an extended outage. The communication system currently communicates through a modem which is also outdated.

The fuel systems are an integral part of the Park’s infrastructure. The fuel pumps service all of the fleet vehicles which support all elements of park operations which include, maintenance, emergency services, resource and visitor protection, and resource management. Having use of on-site fuel systems eliminate the commute required to obtain fuel from Naples or Vernal and creates efficiencies in the use of employees’ time, providing less time for planning and commuting outside of the parks for fuel and more time toward their duties.

2.0 Proposed Location

The project location is at Dinosaur National Monument, Quarry, 11625 E 1500 S, Jensen, UT 84035. The specific Park location is the maintenance area near the Quarry Visitor Center. The new dual compartment tank will be located on the same slab as the existing unleaded ASTs, which is on the east side of the facilities compound next to the maintenance building. Existing ASTs are outlined in yellow in Fig 2.
