MO SB965

Requires the Missouri Air Conservation Commission to establish separate carbon dioxide emissions standards for existing coal-fired and natural gas-fired electric generating units, adjusted on a case-by-case basis.

Coal-fired unit standards must be based on the best demonstrated emission reduction system, achievable reductions through unit-level measures, and efficiency improvements without switching fuels or limiting utilization.

Gas-fired unit standards must apply similar criteria as coal units and include efficiency measures to reduce emissions without switching to lower-carbon fuels or limiting utilization.

Commission must consider whether to adopt less stringent standards or longer compliance schedules based on consumer impacts, unreasonable costs, implementation difficulties, remaining useful life, economic impacts of unit closure including job losses, and other unit-specific factors.

Commission may implement standards through flexible regulatory mechanisms including emissions averaging and trading, but cannot submit plans to the EPA that are inconsistent with this section.
