The town system consists of an infiltration gallery, two 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 and therefore, being vulnerable to a line failure crossing the
The Level II study identified several needed improvements to the Shell
Creek transmission pipeline. These improvements were incorporated into a
Level III rehabilitation project for the town. However the EPA concerns
only recently surfaced.
A Level II evaluation could answer the questions regarding the tanks and
the potential of connecting the area to the southwest.
RECOMMENDED LEGISLATIVE ACTION:
The Commission recommends that the project be accepted into the New
Development Program at Level II with an appropriation of $55,000.
