The Town of Mills is saying that a sewage spill was discovered Monday in the area of Casper Creek and Salt Creek Highway.

The spill has been contained and cleanup efforts are underway, according to a statement from Town Clerk Christine Trumbull.

Few details were immediately available, but people are urged to take precautions when in contact with the water of the North Platte River and Casper Creek from Salt Creek Highway to the Dave Johnson Power Plant.

Trumbull told K2 Radio News that the Wyoming Department of Environmental Quality is working the incident, and pending their work, more information may be available in the next 24 hours.
