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.

A settlement agreement reached with environmental group the Sierra Club last week may mean that Iowa’s largest utility, MidAmerican Energy Co., will switch 674 MW of coal-fired capacity to natural gas or other fuels by April 2016.

A German tax court on Tuesday ruled that the country’s excise tax on nuclear fuel levied since January 2011 is unconstitutional and lacks legal competence. The matter now proceeds to the Federal Constitutional Court, which alone has the jurisdiction to rule on the invalidity of the law.

The Environmental Protection Agency (EPA) issued a final rule in December that strengthens its National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM2.5) to 12.0 micrograms per cubic meter (μg/m³) but declared it would not finalize a proposal to update separate secondary PM2.5 standards. The final rule’s issuance was lauded by environmental and public health groups, though industry groups opposed it, citing concerns that nonattainment areas would suffer economic setbacks.

The Environmental Protection Agency (EPA) on Dec. 20 finalized changes to a specific set of adjustments to the Clean Air Act that apply to coal, oil, natural gas, and biomass boilers and certain solid waste incinerators.
