Company representatives did not immediately return a call for comment. SAN RAMON – Oil company Chevron Corp. called off its planned acquisition of 122 retail gasoline stations in California owned by USA Petroleum Corp. The deal was stopped “for business reasons,” Chevron spokeswoman Stephanie Price said Friday, declining further comment. San Ramon-based Chevron, which last month reported a record quarterly profit of $5 billion, announced the deal in July and said it planned to operate the stations under either the Chevron or Texaco brand. Sen. Barbara Boxer, D-Calif., last month asked the Federal Trade Commission to “thoroughly review” Chevron’s then-pending acquisition.
