MARAMA is cooperating with NESCAUM and the OTC to provide staff support to the Mid-Atlantic and Northeast Regional Planning Organization (MANE-VU). MANE-VU is an organization of states and tribes working together to improve visibility and implement the requirements of EPA's regional haze rule.

Section 16.9A of the Clean Air Act requires the "prevention of any future, and the remedying of any existing, impairment of visibility in Class I areas which impairment results from manmade air pollution."

Class I Areas

Class I areas are national parks exceeding 6000 acres, wilderness areas and national memorial parks exceeding 5000 acres, and all international parks in existence on August 7, 1977.  There are 156 Class I areas in the U.S., including seven in the MANE-VU region:

The specific locaiton and characteristics of the IMPROVE monitoring stations for each Class I area are posted on the Federal Land Manager Environmental Database (FED) and on the IMPROVE website.  

For more information on visibility trends in all U.S. Class I areas, see EPA’s Visibility Website.
