Founded in 1907, WSPA is the oldest petroleum trade association in the United States.Western States Petroleum Association (WSPA) is a non-profit trade association that represents companies that account for the bulk of petroleum exploration, production, refining, transportation and marketing in the five western states of Arizona, California, Nevada, Oregon, and Washington.WSPA is dedicated to ensuring that Americans continue to have reliable access to petroleum and petroleum products through policies that are socially, economically and environmentally responsible. We believe the best way to achieve this goal is through a better understanding of the relevant issues by government leaders, the media and the general public. Toward that end, WSPA works to disseminate accurate information on industry issues and to provide a forum for the exchange of ideas on petroleum matters.WSPA's headquarters are located in Sacramento, California. Additional WSPA locations include offices in Torrance; Bay Area; Santa Barbara; Bakersfield; Scottsdale, Arizona and Olympia, Washington.
