4 IV. SOLUTIONS: IN THE Sulfur Dioxide Emissions from U.S. Power Plants HANDS OF MARYLAND’S POLICYMAKERS Maryland’s policymakers have opportunities to greatly reduce the prob- lem of power plant and incinerator pollu- tion in the state. The General Assembly, the governor, Maryland’s members of Congress, the Maryland Department of the Environment, the Public Service Commission, the Baltimore City Council, and healthcare facilities each have a vital role to play in these solutions.

Solution #1: Control power plant emissions and shift toward clean energy technologies Power plants are Maryland’s leading cause of fine airborne particles and of mercury pollution.
