Test Your Knowledge: Monitoring and Treatment of Closed-Loop Cooling Water Systems

There are often multiple closed-loop water cooling systems installed in a power plant. Chances are good that they cool or control temperature on some very critical components. It can be easy to ignore these systems because they are usually quite reliable. By its very nature, when a closed-loop system remains closed and operates properly for an extended period of time, it is often […]

December 2000—Milledgeville, Ga.: About 35,000 gallons of wastewater laden with coal ash is released from Georgia Power’s Plant Branch into Lake Sinclair when a mechanical failure of an isolation valve causes water from an ash pond to be siphoned back and discharged through the cooling water tunnel system into the lake. Plant Branch has since been retired to meet environmental rules, though the EPA continues to scrutinize three of its five coal ash ponds, which have received a significant or high hazard rating.

Why the EPA’s Proposed Coal Ash Rule Is Concerning

Over the past decade, together with my students and colleagues at Duke University and other academic institutions, I have conducted scientific research and published 13 scientific articles on different aspects

EPA Sets Schedule for Potential ELG Rule Revision

The Environmental Protection Agency (EPA) has issued an official timeline for rulemaking that would potentially revise the Obama administration’s 2015 effluent limitations guidelines and standards (ELGs) for steam electric power plants. In its May 2-released Final 2016 Effluent Guidelines Program Plan, the EPA said it will potentially revise the stringent Best Available Technology (BAT) effluent […]

SCOTUS Sends Controversial WOTUS Rule into More Legal Limbo 

The U.S. Supreme Court unanimously reversed and remanded a rule the Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers rolled out in 2015 that asserts federal authority over small bodies of water with a broader definition of the statutory term, “waters of the U.S.” (WOTUS). In a ruling for National Association of […]
