A sweeping new proposed rule published in the Federal Register by the Environmental Protection Agency (EPA) on April 6 establishes new nitrogen oxide (NOx) emissions budgets that will require fossil fuel–fired power plants in 25 states to participate in an allowance-based ozone season trading program starting in 2023. The proposal, which builds on the agency’s […]

The new rule is long overdue—the last set of trucks standards were developed over two decades ago. Unfortunately, the agency’s proposal is weaker than existing state action and fails to advance the deployment of zero-emission trucks at the pace needed to address the urgent public health crisis caused by tailpipe exhaust.

Vistra Energy will shutter four coal-fired power plants—a total 2 GW—as required by Illinois’ recently revised Multi-Pollutant Standard (MPS) rule, but CEO Curtis Morgan noted the move was “inevitable” due to the changing regulatory environment and unfavorable economic conditions in the MISO market. The company on Aug. 21 said it will close the 54-year-old 915-MW […]

The Environmental Protection Agency (EPA) will refrain from amending the National Ambient Air Quality Standards (NAAQS) for sulfur dioxide (SO2), retaining a 2010 rule, which it said adequately protects public health. The agency on Feb. 25 said in a notice that a periodically required review of the primary—or health-based—rule concluded no revision was necessary. The […]
