About GPA Midstream Membership
Membership in the association follows the calendar year and is open to any organization (partnership, firm or corporation) or individual with an interest in the midstream industry.
Each member falls within one of six dues classes: O1, O2, O3, O4, International and Associate.
- Members in Classes O1, O2, O3 and O4 are determined on the basis of the number of operational hours worked by personnel in that member’s midstream facilities.
- International members are companies that would qualify as operating members (O1-O4), but company headquarters and operations are located outside of the United States.
- Associate members are those that have no midstream operational workhours but have an interest in the midstream industry. (Note: associate members may not manufacture or sell equipment or materials for the midstream industry or engage in construction work for the midstream industry. Companies involved in these activities should join GPSA).
Each member company designates one individual as their GPA Midstream Official Representative. This person represents the company in association business and governance. Once a company joins, any employee of that company is welcome to become involved in GPA Midstream committees and other association activities.
