CONSOL Energy filed a Worker Adjustment and Retaining Notification Act notice saying it will lay off 233 Enlow Fork mine workers on August 31. The mine was idled in mid-April.

About 600 people work at the Enlow Fork mine during full production.

“In these unprecedented times, it is extremely difficult to predict when our production at Enlow Fork mine will return to normal capacity, as it is always our intent to run our operations based on market conditions,” the company said.

“In the interest of keeping our employees informed and meeting all legal requirements, we issued the WARN notice to a portion of employees who will not be recalled from furlough at this time. Situations can certainly change and we will continue to monitor daily,” the company said in a statement.

Enlow Fork is one of three mines that make up the Pennsylvania Mining Complex, which also includes the Bailey mine and Harvey mine.
