Department of Environmental Quality; requiring the promulgation of rules establishing water quality criteria for aluminum; effective date.

HB 2976 requires Oklahoma's Department of Environmental Quality (DEQ) to create rules establishing safe water quality levels for aluminum.

The bill, amended to take effect in 2028, directly impacts the DEQ (which must develop the rules) and industries discharging aluminum into waterways, such as manufacturing or mining operations.
