Bighorn Canyon National Recreational Area

PMIS 308539

1. Project Title Replacement of Electrical Components and Exposed Fuel Line – Ok-a-Beh Marina Fuel System

2. Location Ok-a-Beh Marina Bighorn Canyon National Recreation Area County Road 313 Fort Smith Montana 59035

3. Background The Ok-a-Beh Marina fuel system provides the only fueling capability on Bighorn Reservoir, which is the park’s primary recreational and operational resource. The existing fuel system infrastructure has experienced repeated failures, degraded performance, and non-compliance concerns, resulting in unreliable service to visitors, concession operations, and park staff.

4. Purpose The purpose of this project is to replace critical electrical monitoring components and above-ground fuel piping to restore reliable fuel delivery, improve safety, and bring the system into compliance with applicable codes and standards.

5.1 Mobilization and Coordination

· Coordinate work activities with the NPS Project Manager and the Crow Tribe concession operator.

· Develop a work schedule that minimizes disruption to marina operations and visitor access.

· Conduct a pre-work site visit and safety briefing.

5.2 Removal and Decommissioning

· Safely decommission existing fuel system electrical components.

· Remove approximately 75 linear feet of existing flexible fuel piping from the sump to the fuel dispenser.

· Properly dispose of removed materials in accordance with environmental regulations.

5.3 Installation of Electrical Components

· Install new fuel system electrical components, including:

· Automatic Tank Gauge (ATG)

· Leak detection probe

· Remote communication unit

· Install an electrical disconnect sleeve to meet current electrical and safety code requirements.

5.4 Fuel Piping Installation

· Install approximately 130 linear feet of marina-grade, UL-listed fuel piping.

· Install two fuel line disconnects:

· One at the fuel sump

· One at the bottom of the access stairs

· Ensure all piping and fittings are properly supported, protected, and labeled.

5.5 Testing and Commissioning

· Test the fuel system for:

· Leak detection functionality

· Electrical and communication system performance

· Proper fuel flow and system operation

· Correct any deficiencies identified during testing.

5.6 Site Restoration
