The Environmental Protection Agency (EPA) is proposing to amend its regional haze rule to incorporate additional provisions to address visibility impairment in the 16 Class I areas on the Colorado Plateau. Class I areas are federally protected areas valued for their scenic vistas and include national parks and wilderness areas.
In September 2000, the Western Regional Air Partnership (WRAP) submitted to EPA a plan containing recommendations for implementing the regional haze rule in the Western United States. Specifically, the plan contains a set of recommended regional emissions reduction milestones for sulfur dioxide (SO2), a key compound in the formation of fine particles and regional haze. The plan, also known as the Annex to the 1996 Report of the Grand Canyon Visibility Transport Commission, also included a description of a backstop emissions trading program for nine Western states and eligible Indian tribes within that geographic area. The trading program would ensure that emission milestones would be met.
