This blog has kept a close eye on the Environmental Protection Agency’s aggressive expansion of its own authority (see here and here). The latest such power grab is taking place in the western United States, where the EPA is hybridizing disparate provisions of the Clean Air Act in order to engineer greater regulatory authority for itself. These Franken-regs are being used to trump the states’ rightful authority on visibility-improvement policy and impose billions of dollars of emissions controls for benefits that are literally invisible.
In 1977 and 1990, Congress passed amendments to the Clean Air Act providing that states work together to improve visibility at federal National Parks and Wilderness Areas. Together, these amendments are known as the Regional Haze provision. Notably, this provision accords states a uniquely high degree of control relative to the EPA. According to the EPA’s 2005 Regional Haze implementation guidelines, “[T]he [Clean Air] Act and legislative history indicate that Congress evinced a special concern with insuring that States would be the decision-makers” on visibility-improvement policy making. The courts, too, have interpreted the Clean Air Act such that states have primacy on Regional Haze decision making. In the seminal case American Corn Growers v. EPA (2001), which set boundaries between the states and the EPA on Regional Haze policy, the D.C. Circuit Court remanded the EPA’s 1999 Regional Haze implementation guidelines for encroaching on states’ authority.
