President Obama this week nominated Gina McCarthy, the current assistant administrator for the Environmental Protection Agency (EPA) Office of Air and Radiation, to head the EPA. He also nominated Dr. Ernest Moniz, currently a faculty member at the Massachusetts Institute of Technology (MIT) for secretary of energy. Both are expected to face a difficult confirmation process.

Power plant emissions of sulfur dioxide (SO₂) and nitrogen oxides (NO_x) in the U.S. declined to their lowest level since 1990, the Energy Information Administration (EIA) said last week.

You may be surprised to learn that even with the increased demand for biomass fuels for power generation, construction and demolition fuel is classified as solid waste, not biomass. Reconsidering this designation is critical as U.S. environmental regulations tighten emission profiles for solid waste combustion units and renewable portfolio standards expand.

The lifeblood of the combined cycle plant is its water chemistry program. This is particularly true for plants designed for high pressures and temperatures as well as fast starts and cycling. Even though such plants are increasingly common, no universal chemistry program can be used for all of them.

Mercury emissions from power plants in 137 United Nations member countries could be subject to strict controls and reductions if an international treaty is signed by participating nations this October.

Four bouts of dense smog described as the worst air pollution in recent memory enveloped more than half of China in January, from the Beijing-Tianjin-Hebei triangle in the north of the country to Nanjing in the south, via the central city of Wuhan.

The use of low-grade coal is becoming synonymous with circulating fluidized bed (CFB) power plants. Although CFB technology may often be a better choice than pulverized coal technology, that is not always the case. Owners and developers need to consider several technical and economic factors before making this decision.

Covanta Energy and the City and County of Honolulu recently completed a $300 million expansion of a 20-year-old waste-to-energy (WTE) facility. The plant is now capable of processing up to 3,000 tons of municipal refuse daily, recycling all the metals, and generating up to 90 MW—enough to supply nearly 10% of Oahu’s electricity.

A modified settlement reached between American Electric Power (AEP), a coalition of citizen groups, and the Environmental Protection Agency (EPA) on Monday will allow the utility to install less expensive pollution controls on a coal-fired power plant if it ceases coal combustion by 2015 at three aging power plants in Indiana, Ohio, and Kentucky.

A 20-MW facility in Ford Heights, Ill., that burns waste tires to produce power is to be shut down to resolve allegations by the Environmental Protection Agency (EPA) of Clean Air Act violations.

Dr. Steven Chu gave what was likely his last public speech as U.S. secretary of energy today on the last day of the ARPA-E Energy Innovation Summit. As usual for Chu presentations, it was a mix of data, vision, and humor. It fell to others to comment on the value and legacy of his service, especially to energy research and development.

The Advanced Research Projects Agency-Energy (ARPA-E) may be the most important federal agency many in the power industry have never heard of. Whatever generation technology you are associated with, ARPA-E’s work will affect its future.

Technological progress and policy interventions over the last decade have arguably enhanced U.S. energy security and put it in a stronger position to shape its own energy destiny, a new report from the Bipartisan Policy Center (BPC) argues. Among more than 50 energy policy recommendations outlined in the report to tackle significant challenges still faced by the nation’s energy sector are those calling for the establishment of a comprehensive national energy strategy.

The U.S. House voted 422–0 last week, approving a bill that could facilitate the development of small hydropower and conduit projects and direct the Federal Energy Regulatory Commission (FERC) to consider streamlining its two-year permitting process.

Boosted by President Obama’s inaugural address commitment to mitigate climate change, congressional Democrats have initiated several more climate measures. A legislative packet that seeks to mitigate climate change by enacting a carbon "fee" of $20 per ton of emitted carbon or methane equivalent was introduced last week by Sens. Bernie Sanders (I-Vt.) and Barbara Boxer (D-Calif.). In the House, as several Democratic amendments for climate change hearings were voted down, more than 40 lawmakers urged President Obama to create a panel that would help communities deal with climate change events.

An agreement reached on Friday between PNM, New Mexico’s largest electricity provider, the New Mexico Environment Department (NMED), and the U.S. Environmental Protection Agency (EPA) calls for the retirement of two units at the 1,800-MW coal-fired San Juan Generating Station by 2017 to comply with federal visibility rules. The remaining two units will be retrofitted with selective noncatalytic reduction technology by 2016, a nitrogen-oxide reducing technology.

A think tank affiliated with the New York University School of Law is urging the Environmental Protection Agency (EPA) to mandate cuts of greenhouse gas (GHG) emissions in all 50 U.S. states through a little-used section of the Clean Air Act.

Nine Northeast and Mid-Atlantic states participating in the Regional Greenhouse Gas Initiative (RGGI) will see a 45% lowering of the market-based regulatory program’s carbon dioxide (CO₂) cap in 2014, under an updated model rule released last week. The change is expected to reduce projected 2020 power sector CO₂ emissions from the region to more than 45% below those in 2005.

The U.S. Environmental Protection Agency (EPA) on Friday began accepting comments on its draft Climate Change Adaption Plan, a document that seeks to integrate climate change considerations into future programs and regulations.

New analysis by the World Resources Institute (WRI) finds that the U.S. is not on track to reach its goal of reducing greenhouse gas (GHG) emissions by 17% by 2020 (below 2005 levels) but that it has the tools to get there. Specifically, the report looks at steps the Obama Administration and states can take without congressional action. Those steps would, not surprisingly, require emissions reductions from existing power plants and natural gas systems.

An energy blueprint released on Monday by Sen. Lisa Murkowski (R-Alaska), the ranking minority member of the Senate Energy and Natural Resources Committee, calls for complete independence from OPEC oil by 2020.

The Environmental Protection Agency’s (EPA’s) imposition of a federal implementation plan (FIP) to curb regional haze that could force coal-fired power plants in Arizona to install $1 billion in pollution controls was challenged by the state in federal court last week.

Many power plants have sediment retention ponds that require control of pH for the effluent. The following guidelines for fossil plant sediment pond pH control will help you design a robust system while staying within budget.

Final water intake structure rules from the EPA expected this June suggest the agency may be listening to industry and even moderating its tone. Stretch goals as part of the Section 316(b) rule are likely, but overall the rule may prove more reasonable than many expected.

The U.S. Court of Appeals for the D.C. Circuit last week declined petitions for rehearing en banc of the Cross-State Air Pollution Rule (CSAPR). The federal court’s denial of the petitions leaves in place the Clean Air Interstate Rule (CAIR)—a Bush-era rule that the court had formerly invalidated in July 2008 and then reinstated. It also could prompt environmental groups, 15 states, and the Environmental Protection Agency (EPA) to take their case to the U.S. Supreme Court.

Mississippi regulators last week approved a settlement with Mississippi Power that will allow the Southern Co. subsidiary to seek higher customer rates for rising costs associated with its 582-MW Kemper integrated gasification combined cycle (IGCC) plant under construction in Kemper County. On the day following that ruling, the utility asked the state for permission to recover $172 million for the 2013 regulatory year.
