CHEYENNE, Wyo. (AP) — A group of southeastern Wyoming residents voiced frustrations about recent energy developments to county commissioners, claiming trucks carrying oil and gas drilling equipment continue to speed through residential areas.

The group told Laramie County commissioners on Tuesday that EOG Resources' attempts to slow the vehicles down along County Road 136 appear to be ineffective.

EOG Resources spokeswoman Pam Roth says the company is working to make sure the subcontracted drivers obey the speed limits.

The group also voiced concerns about the company's application to set up an injection well in the area, fearing possible water contamination.

The group advised the commissioners to research the issue and speak up for residents when the matter goes before the Wyoming Oil and Gas Conservation Commission next month.
