Consol Energy Inc. has announced that Chief Commercial Officer James C. Grech has retired, part of a larger "corporate reorganization" effort. In February, the company sold its Buchanan mine and associated metallurgical coal assets for $420 million (see Shale DailyFeb. 29). With Grech's retirement, CNX Coal Resources LP, which operates the Pennsylvania coal assets, will manage all human resources, land, marketing and external communications matters. Consol has coalbed methane operations on some of the properties it sold, but it retained the right to extract and sell that gas.
