Stream Conductivity: It’s Not Just a Mining Issue
Coal mining, and related industries that consume coal, have attracted quite a bit of attention from the federal government as of late. Most of that attention has focused on how to further, or "better," regulate the industry. The EPA is now moving to regulate downstream conductivity of surface mining runoff.

EPA Expands Climate Agenda to the Current Fleet of Power Plants and Refineries
On December 23, 2010, one day before the Yuletide season, when members of Congress, the media, and Tea Party activists are least likely to watchdog the federal bureaucracy, the U.S. Environmental Protection Agency (EPA) announced rulemakings to establish New Source Performance Standards (NSPS) for greenhouse gas (GHG) emissions from power plants and refineries. Or maybe "whispered" would be more accurate.

The Great Solar Storm of 2012?
The 2009 blockbuster movie 2012 about a global cataclysm combined Hollywood special effects with supposed predictions by Nostradamus; a Mayan calendar that ends on December 21, 2012; and a very rare planetary alignment that supposedly occurs on the same day. Hollywood producers seldom let technical accuracy get in the way of a good story, but suppose, this one time, the story has an element of truth.

Continuous SO3 Monitoring Can Reduce Sorbent Consumption
An unintended consequence of employing selective catalytic reduction and wet flue gas desulfurization to reduce nitrogen oxide and sulfur dioxide levels at coal-fired power plants has been unwanted sulfur trioxide (SO3) emissions. Picking the right sorbent in the right amount can eliminate that problem.

Increasing Generation Ramp Rate at Morgantown Generating Station’s Coal-Fired Units
At Morgantown Generating Station, plant personnel used innovative methods to combine model predictive control with distributed control system–based process control algorithms to improve waterwall temperature control and main steam temperature control and to enhance unit ramp rate capability. The previous heat rate and NOx optimization performance gains were retained. Focusing beyond basic loops of feedwater, air, and O2, the project considered issues such as PID controller override configuration and limitations. The techniques used to overcome these challenges improved unit ramp rate capability beyond any previous unit performance.

I&C Update on Plant Vogtle Units 3 and 4
Development of Vogtle Electric Generating Station Units 3 and 4—the first new nuclear power plant units in the U.S. in decades—has generated considerable excitement. The next generation of nuclear plants, represented by these units, includes at least two major improvements: the use of passive safety systems and a reliance on digital control systems. The latter represents a gigantic leap in modernization and a fundamental change in control of the plant.
