Committees within WESTAR address key technical and policy issues important to the member states. There are currently four WESTAR operating committees: Sources, Technical, Planning, and Mobile Sources. Two of these committees are currently inactive: the Sources and Mobile Sources Committees. The general areas of responsibility for the committees are summarized below. Each of the committees is charged with identifying and, if appropriate, addressing issues related to their assigned areas of responsibility, through sharing of information amongst states; tracking the activities of other national and regional air quality management organizations; identifying the need for, and where appropriate, recommending and advocating for policy change; and developing guidance documents and compiling and sharing information.
Workgroups are formed to address specific issues or tasks. Once their work is completed the workgroup is either discontinued or deactivated until the WESTAR directors direct staff to re-activate the workgroup, either as follow up to a previously addressed issue or project, or for a new assignment. Workgroup products are typically presented to the directors at membership meetings or during periodic conference calls. Once approved by the directors, work products are typically posted on WESTAR's website. Recent examples include:
