CASPER, Wyo. (AP) — Officials in Mills are asking Natrona County to reconsider its conditional approval of a drilling-mud recycling plant just outside the town's border.

According to the Associated Press, Mayor Elsie Herbort sent a letter to county commissioners this week criticizing them for their decision. Leaders in the town are worried about road use, dangerous chemicals and smells from the plant.

The county posted signs and legal notices before voting on the Anchor Environmental project but didn't directly notify Mills, which eventually plans to build in the area at issue.

Natrona County commission chairman Ed Opella said he'll see if any members want to reconsider their decision. However, he pointed out that the final word on whether the plant is built will come from the state's Solid and Hazardous Waste Division.
