WPMA is made up of seven separate state associations, including Hawaii, Idaho, Montana, Nevada, New Mexico, Utah and Washington. Originally, marketers from the states of Utah, Idaho, and Nevada formed the association with marketers from Arizona, Montana and Eastern Washington, known as the Inland Empire, joining soon after. Most of the states organized with their own officers in the late 1960's. Washington state marketers unified and joined the IOMA (WPMA) in 1982 with the Inland Empire in the east and the WOMA association in the west. The state of New Mexico joined the WPMA Association in January 1992, and Hawaii marketers became members in 1993. Each state association is organized with a President, Vice President, PMAA Director and area directors. Most have a State Executive who administers state programs under the direction of the State Board of Directors. These duties include lobbying state legislatures, representation before state government agencies, membership services, and state convention management. Each state provides three officers (President, Vice President and PMAA Director) who sit on the WPMA Board of Directors. All of the state associations are members of the Petroleum Marketers Association of America (PMAA) which represents petroleum marketers on national issues in Washington D.C. Each state is able to have one marketer seated on the PMAA Board.
