The U.S. Supreme Court in a 5–4 vote blocked enforcement of the Environmental Protection Agency’s (EPA’s) final “Good Neighbor Plan,” a rule intended to significantly cut smog-forming nitrogen oxide (NOx) pollution from power plants and other industrial facilities in 23 states. In the meantime, the applicants, which include the states of Ohio, Indiana, and West […]

The Environmental Protection Agency (EPA) on March 15 issued the final “Good Neighbor Plan,” its latest iteration of the Cross-State Air Pollution Rule (CSAPR) that could require coal, oil, or gas steam power plants in 22 states to reduce their nitrogen oxide (NOx) emissions levels by 50% by 2027 compared to the 2021 ozone season. […]

A group of researchers found that “Adopting electric end-use technologies instead of fossil-fueled alternatives, known as electrification, is an important economy-wide decarbonization strategy that also reduces criteria pollutant emissions and improves air quality.” Findings from the study conducted by nine researchers—four from EPRI, four from Ramboll, and one from the Oak Ridge National Laboratory—were published […]

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 Environmental Protection Agency (EPA) does not intend to revisit national ambient air quality standards (NAAQS) for ozone that the Obama administration issued in 2015, a court filing shows.  The agency said in its final status report submitted to the U.S. Court of Appeals for the D.C. Circuit on August 1 that it has reviewed […]

The D.C. Circuit last week struck down parts of an Environmental Protection Agency (EPA) rule concerning implementation of its 2008 ozone standards, creating new regulatory limbo for the entities required to comply with the rule. Ruling in a set of cases consolidated under South Coast Air Quality Management District v. EPA (No. 15-1115), the federal […]

New York and Connecticut on January 17 filed suit to force the Environmental Protection Agency (EPA) to curb ground-level ozone blowing in from Illinois, Michigan, Pennsylvania, Virginia, and West Virginia with federal implementation plans (FIPs) issued under the “Good Neighbor Provision” of the 2008 National Ambient Air Quality Standards (NAAQS). The two states allege in their […]

Eight northeastern states are again suing the Environmental Protection Agency (EPA) to force the agency to slash emissions of nitrogen oxides (NOx) and volatile organic compounds (VOCs) blowing in from power plants and other sources in nine “upwind” Midwestern and southern states. The Ozone Transport Region, which was established by Congress under Section 184 of […]

The Environmental Protection Agency (EPA) is giving states an extra year to develop air quality plans related to the 2015-National Ambient Air Quality Standards (NAAQS) for ground-level ozone. In a June 6 letter sent to U.S. governors, EPA Administrator Scott Pruitt announced that the extended deadline for promulgating initial area designations for the rule issued […]

POWER‘s monthly infographic sheds light on power sector trends globally, and in 2015, it highlighted changes in plant retirements, sector revenues, rule costs, workforce, emissions technologies, and electricity costs, among other subjects. January 2015: Baseload Retirements How coal plant retirements compare with retirements of other baseload generation sources. February 2015: Power Revenues How revenues for fossil power […]
