{Bristol, Virginia}...Bristol, Va.-based Alpha Natural Resources has appointed Paul Vining as the company's president, assuming the duties of the retiring Kurt Kost, who is leaving the company in May after 31 years of service, but will still serve in an advisory capacity following his retirement. Alpha officials said Wednesday that Vining, who first joined Alpha in 2011, is adding to his sales and marketing responsibilities as Alpha's chief commercial officer. CEO Kevin Crutchfield says combining the company's mining operations with its sales and marketing efforts will create the most effective business model for Alpha, which has more than 180 mines and processing plants in Kentucky, Pennsylvania, Virginia, West Virginia and Wyoming. It employs about 14,000 people through its affiliates.
