345-024-0500 Standards for Fossil-Fueled Power Plants and Energy Facilities that Emit Carbon Dioxide (1) Notwithstanding OAR 345-024-0503 through 345-024-0720, to issue a site certificate for a fossil-fueled power plant on or after September 25, 2021, the Council must find that the facility will only generate electricity in a manner that does not emit greenhouse gasses into the atmosphere. (2) If the facility will rely on carbon capture, sequestration, and storage to satisfy the requirements of section (1), the Council must find that the certificate holder has demonstrated that the structures, systems, components, and monitoring programs at the facility are reasonably likely to result in the permanent capture, sequestration, and storage of greenhouse gasses that result from the generation of electricity at the facility. (3) To issue a site certificate for a nongenerating facility that will emit carbon dioxide into the atmosphere, the Council must find that the energy facility complies with the carbon dioxide emissions standard under OAR 345-024-0620. (4) In addition to the requirements of OAR 345, division 22, in an application for a site certificate for a fossil-fueled power plant, or other facility that will emit carbon dioxide into the atmosphere, the application must include the following: (a) A description of the means by which the applicant will comply with the applicable carbon dioxide emissions standard under OAR 345-024-0500.
