The Justice Department and the U.S. Environmental Protection Agency announced settlements with oil and gas operators in Pennsylvania, which will net money for counties, including Butler County, where the operators allegedly violated federal guidelines.

In separate agreements, XTO Energy and Hilcorp Energy Company (Hilcorp) agreed to resolve alleged Clean Air Act and Pennsylvania Air Pollution Control Act violations involving their oil and gas production operations in Pennsylvania.

XTO agreed to pay a $4 million civil penalty, and Hilcorp agreed to pay a $1.275 million civil penalty, according to the Department of Justice. The money will be shared equally by the United States and Pennsylvania.

In addition to the civil penalties, both companies will undertake compliance measures to achieve major reductions in harmful emissions at their oil and gas production facilities.

The settlements were announced Thursday, Nov. 21.
