Question

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

Explanation:

The 1970 Clean Air Act aimed at improving air quality. State - level air pollution reduction plans are in line with the act's goal of reducing pollutants. Increasing air pollution emission plans (opposes the act's purpose), plans to build prisons for heavy polluters (not a direct requirement of the 1970 act's main focus on pollution reduction mechanisms), and plans to increase coal - burning energy (coal - burning is a major source of air pollution, which goes against the act's intent) are incorrect.

Answer:

state - level air pollution reduction plans
