About Workgroups
GPA Midstream committees form workgroups to tackle special projects and address specific issues important to the midstream industry. Workgroups are comprised of volunteers from GPA Midstream and GPSA member companies.
To participate in a workgroup, please contact the GPA Midstream Staff Liaison of the workgroup’s committee.
