The District’s attorney general said Wednesday that his office is investigating the city’s largest owner of gas stations for potential antitrust violations.
Attorney General Irvin B. Nathan said that his office is looking into allegations that Capitol Petroleum Group was engaging in practices that could be leading to inflated pump prices.
“Everyone knows that gasoline prices are high,” Nathan said, “and we’re going to do everything we can to bring them down and be sure that it is a competitive market.”
Capitol Petroleum, based in Springfield, is a regional behemoth, netting $778 million in revenue in 2010, according to its Web site. It “owns, operates or supplies” 164 stations in the D.C. area and 71 stations in New York City.
Its primary owner, Eyob “Joe” Mamo, has built the company over nearly 25 years, buying up dozens of service stations in the region — particularly in the past three years. A February Washington City Paper profile of Mamo said the Ethiopian immigrant owned 45 gas stations in the city limits, about half the District’s total, and about one-fourth of the region’s stations.
Nathan said his investigation will probe whether Mamo’s recent expansion of his service station holdings represents an illegal monopoly under the District’s local antitrust law, which is modeled on the federal statute. The investigation might also explore whether Mamo’s dual role as a station owner and gas wholesaler represents an illegal restraint of trade.
