 50. PROJECT:Greybull Crossing & Tank
SPONSOR:Town of Greybull
LOCATION:Big Horn County
PROGRAM:New Development
Purpose Chapter Session Account Appropriation Due Date
Level II 46 1997 I $55,000   1998
Level III 96 2000 I $1,850,000* 2004
*60% Grant & 40% Loan (7 1/4%, 20 years)

The Town of Greybull system consists of an infiltration gallery, three flowing wells, two tanks with 1.3 million gallons of storage, and a number of manual and automatic control valves. The town is under administrative order from EPA for violations of the Surface Water Treatment Rule associated with the diversion through their infiltration gallery on Shell Creek. EPA has recommended that the town add storage on the west side of the river. Currently the town's only storage facility is located on the east side of the river. This situation leaves them vulnerable to a line failure at their river crossing. In addition, residents southwest of Greybull have requested water service.

The Level II study makes recommendations regarding additional storage, transmission and distribution lines that will resolve the town's storage problems, provide water to areas adjacent to town, and provide for more efficient operation of the system.

The town has selected an engineer to design new, redundant river crossing, pipeline and storage facilities. The plans and specifications are complete and construction has started on the first phase of the project and will be completed in 2003. Phase I consists of piping east of the Big Horn River and the river crossing. Phase II of the project is on hold pending resolution of difficulties with crossing the old refinery site. Phase II of the project includes transmission pipeline and a storage tank west of town. Construction of Phase II is expected during 2003.

No legislative action required.
