The preliminary approval marks another important […]

Illinois on May 27 became the third state in the nation to pass legislation requiring coal ash protections beyond federal requirements.  The state’s House passed the Coal Ash Pollution Prevention Act (SB 9) in a 77-36 vote on Monday, only weeks after Senate passage of the bill in a 39-9 vote on May 9. The […]

The U.S. Environmental Protection Agency (EPA) will act on a spate of power plant rules over the next year, its newly released agenda of regulatory and deregulatory actions shows. The May 23-released “Spring 2019 Agenda of Regulatory and Deregulatory Actions” lists 35 new actions, along with 57 actions that it considers “deregulatory.” The list includes new […]

Evolving environmental regulations have forced many coal power plant operators to re-evaluate how they handle water and ash. Many units have been retrofit with dry handling systems, but there are other

In a legal victory for environmental groups, a federal court has vacated key portions of the Environmental Protection Agency’s (EPA’s) November 2015-promulgated effluent limitations guidelines (ELGs) for steam electric power plants, deeming them “unlawful.”  The decision adds a dramatic new element of uncertainty in timing of the rule, which the Trump administration has said it […]

North Carolina officials have ordered Duke Energy to excavate all its coal ash storage ponds in the state, saying the utility’s current plan for its coal ash sites does not sufficiently protect groundwater.

An estimated 91% of U.S. coal power plants that submitted groundwater monitoring data as required by the Environmental Protection Agency’s (EPA’s) 2015 Coal Combustion Residuals (CCR) rule have unsafe levels of one or more contaminants, a collaborative analysis of the monitoring data by several environmental groups suggests.  The March 4 report is significant because power […]

An Alabama power plant that has operated for more than a century will close in April, with Alabama Power saying that the cost to comply with government regulations on the handling of coal ash and wastewater no longer make the plant economically viable. Jim Heilbron, Alabama Power’s senior vice president and senior production officer, on […]

Thousands of workers are involved, and billions of dollars are being spent, as U.S. utilities convert and close dozens of coal ash impoundments in an effort to meet government regulations and prevent future

Analysis based on testing mostly conducted by energy companies shows that water near all but two coal plants in Illinois is contaminated with toxic waste. The Chicago Tribune on November 28 reported that a compilation of industry-supplied data from 24 Illinois coal plants shows harmful levels of arsenic, chromium, lead, and other heavy metals in […]

Environmental officials in North Carolina say their tests show that coal ash released from Duke Energy’s Sutton power plant in Wilmington during flooding from Hurricane Florence has not had a negative impact on the Cape Fear River. The state’s Department of Environmental Quality (DEQ) on October 4 said its test results on water samples collected […]

Hurricane Florence floodwaters have breached a cooling lake dam at Duke Energy’s Sutton Plant in Wilmington, North Carolina, releasing water into the Cape Fear River and flooding the footprint of the gas plant at the site, which has been shut down.  The company’s latest update signals mounting troubles at the site, where Duke Energy shuttered […]

President Trump campaigned on a promise to reduce regulation and control regulatory costs. One of his first actions after taking office was to issue an executive order calling for the elimination of two existing regulations for every one new regulation issued. Toward that end, the Trump administration has acted or sought to reverse more than […]

Dry Fork Station began commercial operation as a swath of older, less-efficient U.S. coal plants contemplated retirement amid a flood of environmental rules. Designed with foresight, this quintessential modern

The Trump administration has finalized a significantly weakened rule governing the disposal of coal ash in landfills and surface impoundments by coal generators nationwide. The Environmental Protection Agency (EPA) revealed on July 18 that it signed the first rule of its two-part rulemaking set that overhauls the Obama administration’s final 2015 rules for the disposal […]
