A new report from the U.S. Chamber of Commerce claims that the Environmental Protection Agency (EPA) uses a regulatory tactic dubbed “sue and settle rulemaking” to force states to relinquish their authority and accept agency-promulgated plans to mitigate regional haze that are much costlier to implement.

Most steam generator tube wear or tube wall thinning at Southern California Edison’s (SCE’s) two-reactor San Onofre Generating Station (SONGS) was less than 20%—far below the 35% wall-thinning limit that would require the tubes to be plugged, data released last week by the Nuclear Regulatory Commission shows. Much of the wear was not "unusual," SCE said in a statement.

The $2 billion Potomac Appalachian Transmission Highline (PATH) may be canceled this fall, a project analysis update from PJM Interconnection suggests. The grid operator for 13 states suspended the 765-kV project last year pending further analysis.

Owners of the Wolf Creek Nuclear Power Plant in Kansas are entitled to $12.6 million in damages stemming from the federal government’s partial breach of a contract for disposal of spent nuclear fuel, $2 million more than previously awarded, a federal court ruled last week.

The Environmental Protection Agency (EPA) last week promulgated a final rule that does not revise the greenhouse gas (GHG) permitting thresholds that were established in Step 1 and Step 2 of the GHG Tailoring Rule. The final rule, which comes just days after a federal appeals court ruled the EPA was “unambiguously correct” in its interpretation of the Clean Air Act to regulate carbon dioxide emissions, is the third step of the agency’s phased-in approach to GHG permitting under the Clean Air Act.

Utilities in the Canadian province of Alberta were on Monday forced to institute rolling blackouts as soaring summer temperatures drove demand for electricity to an all-time high and six generators–four coal plants and two natural gas plants–entered unplanned outages.

Mississippi Power on Monday asked the Mississippi Supreme Court to review the June 22 unanimous denial by three commissioners of the Mississippi Public Service Commission (MPSC) of the company’s request to recover financing costs for its 582-MW Kemper County Integrated Gasification Combined Cycle (IGCC) plant.

Finnish utility Teollisuuden Voima Oyj (TVO)—operator of the Olkiluoto 3 (OL3) nuclear power plant under construction in Finland, a project that could be the world’s first EPR reactor but that has faced costly delays—must release €125 million ($155 million) of withheld payments to an AREVA-Siemens consortium, an international arbitration court ordered last week.

Ontario’s provincial government has persuaded the owner of an unpopular 280-MW natural gas-fired power plant that was already under construction in the City of Mississauga to relocate the project to an existing power plant site in southwestern Ontario. The agreement settles legal challenges to the government’s proposals to cancel the project.

Dr. Allison Macfarlane, an expert on nuclear waste issues and a member of the Blue Ribbon Commission on America’s Nuclear Future, was on Monday sworn in as the 15th person chosen to lead the Nuclear Regulatory Commission (NRC). She will serve a term ending June 30, 2013.
