The U.S. Environmental Protection Agency (EPA) is providing notice of the availability of data on the administration of the assurance provisions of the Cross-State Air Pollution Rule (CSAPR) trading program for the 2025 control period. Virginia units participating in the CSAPR NO<INF>X</INF> Ozone Season Group 2E Trading Program during the 2025 control period reported total nitrogen oxides (NO<INF>X</INF>) emissions that exceeded the State's assurance level under the program. The EPA has posted on the Agency's website a spreadsheet that presents data demonstrating the exceedance and the Agency's final calculations of the additional allowances that owners and operators of certain Virginia units must surrender.
