The first segment involved the operation of six petroleum refineries situated in California, Alaska, Washington, Hawaii, North Dakota, and Utah.[8] For its marketing and distribution segment, Tesoro sold refined gas and fuel products in both bulk and wholesale markets.[8] Acquisitions expanded refining capacity from 72,000 barrels per day (11,400 m3/d) to approximately 664,000 barrels per day (105,600 m3/d).

Media controversyedit
Environmental recordedit
Having taken over BP installations, researchers at the Political Economy Research Institute identified Tesoro as being the 24th-largest corporate producer of air pollution in the United States, releasing roughly 3,740,000 lb (1,700 t) of toxic chemicals annually.[22] Major pollutants emitted annually by the corporation were estimated to include more than 400,000 lb (180 t) of sulfuric acid,[23]
following which the Environmental Protection Agency named Tesoro a potentially responsible party for at least four superfund toxic waste sites.[24]
Tesoro settled and/or closed each of the superfund sites where it was named as one of many responsible parties. Tesoro was listed as a de minimis contributor to a superfund site in Abbeville, LA, and the site has since been closed by the EPA.
Defenders of the Amazon forest in South America cite Tesoro for sourcing some of their crude oil from the Amazon. Three of Tesoro's refineries - Anacortes (WA), LA (CA) and Golden Eagle (CA), were known to process Amazonian crude oil.[26]
