A pair of 1981 alumni, John S. Swearingen and George P. Shaffner, has been appointed to new senior vice president roles in a series of key management changes announced recently by Marathon Petroleum Corp. (MPC), the nation's fourth-largest oil refiner.

Swearingen, a chemical engineering graduate, will be vice president and chief operating officer of MPC's pipeline and logistics subsidiary, replacing Shaffner, who served in that role since the subsidiary's initial public offering in 2012. Swearingen will support Pamela K.M. Beall, president of Marathon Petroleum Corp.'s pipeline and logistics subsidiary. He reports to Donald C. Templin, executive vice president of supply, transportation, and marketing.

Meanwhile, Shaffner, a mechanical engineering graduate, is now in charge of health, environment, safety, and security, and reports to MPC President and Chief Executive Officer Gary R. Heminger.

Heminger states in a company news release that "George's extensive operating experience and strong commitment to our environmental and safety values will greatly benefit our health, environment, safety, and security function, while John's breadth of refining experience and previous role as president of Marathon Pipe Line LLC will serve the transportation and logistics organization well."

Swearingen and Shaffner will remain at MPC's headquarters in Findlay, Ohio.

Marathon Petroleum's seven-refinery system produces gasoline sold through approximately 5,460 independently owned retail outlets across 19 states. In addition, the Speedway MPC subsidiary owns and operates the nation's second-largest convenience store chain.
