FirstEnergy Nuclear Operating Co.’s (FENOC’s) conclusion that cracks in the shield building at the Davis-Besse Nuclear Power Station in Oak Harbor, Ohio, were caused by environmental factors resulting from a blizzard in 1978 and aspects of the shield building’s design is sound, the Nuclear Regulatory Commission (NRC) said on Thursday.

The U.S. Supreme Court on Monday denied review of a case in which several states and citizen groups contend that the Federal Energy Regulatory Commission’s (FERC’s) Order 697—issued in 2007 to improve market-based rate regulations—exceeds FERC’s authority under the Federal Power Act (FPA).

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on Tuesday ruled that the U.S. Environmental Protection Agency (EPA) was "unambiguously correct" in its interpretation of the Clean Air Act (CAA) to regulate carbon dioxide emissions. The federal agency’s endangerment finding that greenhouse gases (GHG), including carbon dioxide, are a threat to public health and welfare, and its decision to set limits for industrial and automotive emissions of GHGs, was "neither arbitrary nor capricious," the court ruled. The court, however, found that it lacked jurisdiction to review the timing and scope of the GHG rules that affect larger stationary sources, including new coal-fired power plants.

The State of Vermont "repeatedly failed" to present to the Nuclear Regulatory Commission (NRC) objections that Entergy Corp., owner of the controversial Vermont Yankee Nuclear Power Station, lacked a necessary state water permit before the commission granted the reactor a 20-year operating license extension, a federal court ruled on Tuesday as it threw out the state’s legal challenge against the NRC.

The U.S. Army Corps of Engineers properly followed permitting procedures when it verified that Puget Sound Energy (PSE) could lower a dam in the single narrow channel above Washington State’s landmark Snoqualmie Falls to mitigate flooding issues upstream, the U.S. Court of Appeals for the Ninth Circuit ruled on Tuesday.

The Federal Energy Regulatory Commission (FERC) finalized a key rule that intends to facilitate the integration of variable energy resources (VERs) and proposed another that clarifies the reporting of transactions involving energy storage facilities. The body also announced in the past week that it would soon eliminate the current system used by public utilities to report required electricity data on a quarterly basis, as well as approve the North American Electric Reliability Corp.’s (NERC’s) revisions to the definition of the bulk electric system.

International pushback against China’s export restraints on rare earth elements, tungsten, and molybdenum intensified on Wednesday as the U.S., the European Union (EU), and Japan asked the World Trade Organization (WTO) to establish a dispute settlement panel to vet the matter.

A federal court on Friday granted a request by Oklahoma for a stay of the U.S. Environmental Protection Agency’s (EPA’s) final rule requiring the reduction of sulfur dioxide emissions at four electric generating units in the state pending a review of the rule.

In response to a court order, the U.S. Environmental Protection Agency (EPA) proposed updates on Friday to its national air quality standards for harmful fine particle pollution, including soot (known as PM2.5). The agency says that 99% of U.S. counties are projected to meet proposed standards without any additional actions.

The United States is in a "fierce race" to compete in global solar energy markets, and its success depends on innovation and deploying solar energy at scale, said Steven Chu, secretary of the Department of Energy. He spoke at the SunShot Grand Challenge summit and technology forum in Denver last week. Chu called on the solar industry to drive down costs to enable the technology to compete against natural gas at a price of around $4 per million Btu.
