Within its boundary,
Michigan
has two Class I areas -
Isle Royale
National Park
and Seney Wilderness Area. By December 2007,
Michigan
must submit to EPA a CAVR State Implementation Plan (SIP) that identifies sources that cause or contribute to visibility impairment in these areas. The CAVR SIP must also include a demonstration of reasonable progress toward reaching the first incremental progress goal (2018) for each of the state's Class I areas.

History:
In July 1999 the U.S. Environmental Protection Agency (EPA) published regulations to address visibility impairment in our nation's largest national parks and wilderness (Class I) areas. This rule was commonly known as the "Regional Haze Rule" (64 Fed. Reg. 35714 [July, 1999]) and is found in 40 CFR part 51, in §§ 51.300 through 51.309. Under EPA's 1999 Regional Haze Rule, certain emission sources "that may reasonably be anticipated to cause or contribute" to visibility impairment in downwind Class I areas are required to install Best Available Retrofit Technology (BART). On
July 6, 2005
, EPA published a revised final rule, including Appendix Y to 40 CFR part 51, "Guidelines for BART Determinations Under the Regional Haze Rule" (Guidelines). Most recently, EPA began referring to the Regional Haze Rule and BART requirements as the Clean Air Visibility Rule (CAVR)
