Greenhouse Gas Standards and Guidelines for Fossil Fuel-Fired Power Plants

There are no currently active Public Notices/ Public Comments. When the draft plan is available for public review and comment, it will be posted here along with information on any public hearings for the draft plan.

The department values stakeholder’s feedback and input throughout development of Missouri's plan. The department will hold public meetings to provide updates and solicit input on the development of the plan. All stakeholders are encouraged to attend the public meetings. Pertinent stakeholders may include, but are not limited to, the public, communities located near affected power plants, the energy communities, and workers; industry; other state and local regulatory agencies, reliability coordinators; and small businesses.

All department events and meetings, including dates, times and locations, are available by accessing the department calendar.

On May 9, 2024, EPA published a final federal rulemaking that – 

• Repealed the Affordable Clean Energy (ACE) Rule
• Issued final revisions to the New Source Performance Standards (NSPS) for greenhouse gas emissions from new and reconstructed combustion turbines at power plants
• Issued final revisions to the NSPS for greenhouse gas emissions from modified coal-fired boilers at power plants
• Issued final guidelines for greenhouse gas emissions from existing fossil-fuel fired boilers at power plants

For more information, including a rule summary, rule history and additional resource, please review EPA's Greenhouse Gas Standards and Guidelines for Fossil Fuel-Fired Power Plants webpage.

Missouri's plan to control CO₂ emissions from existing power plants is due to EPA by May 11, 2026. The Missouri Department of Natural Resources' Air Pollution Control Program currently is developing the state plan to address this federal regulation. The department also is developing an implementation impact report for this plan. 

EPA’s regulations for CAA section 111(d) state plans for existing sources require ongoing meaningful engagement during the planning process. The state must document that meaningful engagement was conducted with pertinent stakeholders during plan development. This documentation must be submitted with the state plan, and includes the following:

• List of pertinent stakeholders as identified by the state
• Summary of the engagement conducted
• Summary of stakeholder input received
• Description of how stakeholder input was considered in the development of the plan or plan revisions
