Which company built the last new refinery in the United States in 1976?

• A. ExxonMobil
• B. Chevron
• C. BP
• D. Marathon Petroleum

Answer: (D)

The idea being tested is understanding how U.S. refining capacity was built and how that trend shifted after the 1970s. The fact here is that the United States did not see another brand-new refinery start after 1976, making that year notable. Marathon, through its predecessor companies, completed the last new refinery project in 1976. After that, the industry moved toward expanding and upgrading existing plants rather than constructing entirely new greenfield refineries. That shift happened because building a new refinery required enormous capital, and the regulatory environment—plus siting challenges and public opposition—made fresh greenfield projects far less attractive. The other major companies listed did not establish a new, completely new refinery in that year, even though they continued to operate and occasionally upgrade or expand their existing facilities.
