Class 1 federal lands include areas such as national parks, national wilderness areas, and national monuments. These areas are granted special air quality protections under Section 162(a) of the federal Clean Air Act.
40 CFR Section 51.307 requires the operator of any new major stationary source or major modification located within 100 kilometers of a Class I area to contact the Federal Land Managers for that area.
