An example of a federal action or decision that falls under the requirements of NEPA would be the permitting of a new mine development on federal lands. National Environmental Policy Act (NEPA): NEPA requires all federal agencies to prepare environmental impact statements on major federal actions that are deemed to have a significant impact on the quality of the environment. Some scenarios that could fall under the CAA include exhaust emissions from heavy equipment, or emissions from processing facilities. It covers a wide range of pollutants, including sulfur dioxide, carbon monoxide, and mercury. States are obligated to devise plans to achieve the air quality standards. It requires national ambient air quality standards to be set. Ĭlean Air Act (CAA): The CAA is another federal statute enacted for the protection and enhancement of the Nation’s air quality for fostering public health, welfare, and productive capacity of the population. The CWA can cover activities like the disposal of mining-related waters and control of seeps from mine tailings impoundments. It requires permits to be attained in certain instances, such as National Pollutant Discharge Elimination System (NPDES) permits or permits for the disposal of dredge and fill material.
