Question

what did the federal government instruct states to create in response to the 1970 clean air acts requirements? plans to increase coal burning energy plans to build prisons for heavy polluters state - level air pollution reduction plans increasing air pollution emission plans

Explanation:

The 1970 Clean Air Act aimed to reduce air pollution. Increasing coal burning (first option) or emissions (fourth option) goes against this goal. Building prisons for polluters (second option) is not a standard response to the Act. The Act required states to develop plans to reduce air pollution at the state level, so the third option is correct.

Answer:

state - level air pollution reduction plans
