GHG Emissions Regulation
Vistra Corp. · 2026-11-09 · Importance 47 · Surprise 60 · In source text
In September 2026, the EPA published a final rule repealing most provisions of the 2024 Carbon Pollution Standards Rule, which had set limits for new natural gas-fired turbines and existing coal-, oil- and gas-fired steam units. The repeal removes the CCS requirement for existing coal units and emission guidelines for existing fossil-fuel steam units, as well as CCS standards for new baseload natural gas turbines. Vistra says Martin Lake and Oak Grove were its only coal units subject to the 2024 Rule, and Graham, Lake Hubbard, Stryker Creek and Trinidad were also regulated; a proposed full repeal could also remove standards for the new Permian natural-gas peaking plant and other new units. Environmental organizations and states have challenged the repeal in the D.C. Circuit, while the EPA has separately proposed further action to repeal all Clean Air Act Section 111 GHG standards for electric generating units.
Key facts
- In September 2026, the EPA published a final rule repealing most provisions of the 2024 Carbon Pollution Standards Rule, including its emissions guidelines for existing coal-, oil-, and gas-fired steam generating units and CCS standards for new base-load natural gas-fired turbines. source
- Vistra's existing large and small combustion turbines were not subject to the 2024 Carbon Pollution Standards Rule; if the proposed full repeal is adopted, its new Permian natural-gas-fueled peaking plant and other new units would no longer be subject to the standards. source
- The EPA's 2024 Carbon Pollution Standards Rule exempted units permanently retiring by January 1, 2032; under Vistra's previously announced coal retirement commitments, Martin Lake and Oak Grove were its only coal units subject to the rule. source
- Vistra's Graham, Lake Hubbard, Stryker Creek, and Trinidad oil and natural gas facilities were regulated under the 2024 Carbon Pollution Standards Rule. source
