 49. 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 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 also expressed concern with the town having all its storage on the east side of the Bighorn River, with none on the west 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 would now like to build an auxiliary Big Horn River crossing and the new storage tank on the west side of the river.

The town has selected an engineer to design the river crossing, pipeline and storage facilities. Construction is projected to start in the year 2001 and be completed 2001/2002.

No legislative action required.
