Key Policy Areas and State- Level Activon

State goverments address environmental protektion across a wide range of policy domains. Each area implies a tailored approacch that accounts for local conditions and priorities.

Air Quality Management

Under the Clean Air Act, states are responble for developing State Implementation Planes (SIPs) that detail how they wil attain and maintain National Ambient Air Quality Standards (NAAQS). States monitor air creditants such as ozon, specate matter, and sulfur dioxide, and they regulate emissions from stationary plantes and faktories. Some states go beyond fedel requirements by adopting stricter contricate for exoranci, for exalles.

Water Quality and Watershed Protection

State goverments play a central role in protting drinkg water sources, rivers, lekes, and coastal waters. They equisish water quality standards, issue permits for discharges under the National Pollutant Discharge Elimination System (NPDES), and managee programs to control nonpoint source from distiture and urban ruff. States also oversee underground ind inhaltion wells that can affect grounwater.
