Pursuant to the Governor's Executive Order of regulatory improvement, the Air Resources Board has reviewed its regulations and determined that the identified regulations should be eliminated in part and replaced in part. Those portions of the regulations to be replaced would be maintained in a fashion that would presumably be more accessible to the public.

Staff proposes amendments in response to Assembly Bill 421, which requires the Air Resources Board to divide the Southeast Desert Air Basin, and to a request by the South Coast Air Quality Management District to realign the air basin boundary between the South Coast and Southeast Desert air basins.

The GCVTC is mandated by the 1990 Federal Clean Air Act to recommend to the U.S. EPA by June 1996 actions necessary to protect and enhance visual air quality at Grand Canyon National Park and other Class I areas on the Colorado plateau. The GCVTC's Technical Committee has completed analyses of the origin and transport of air pollution across the western U.S.; its Alternative Assessment Committees have estimated the costs and benefits of various potential control strategies; and its Operations and Public Advisory Committees have approved a "consensus" recommendation for consideration by the Commission for regional visual air quality management through the early decades of the next century. The Commission (consisting of Governors, tribal leaders, and federal land managers) will meet June 10, 1996 at Grand Canyon National Park to adopt a final recommendation to the U.S. EPA, which must issue visibility regulations by January 1998.
