Of the three ways to comply with the Mercury and Air Toxics Standards for particulate matter (PM) measurement, using an optical PM continuous emissions monitoring system (CEMS) also delivers valuable side benefits, especially for units using wet flue gas desulfurization (FGD).  Editor’s Note: This issue was published before the June 29, 2015, ruling by the […]

As the Chinese government lowers the particulate matter (PM2.5) limits to 5 mg/Nm3 or less in coal-fired power plants, wet electrostatic precipitators are one of the key environmental components utilities select to meet this requirement. Optimization of continuous water washing of electrodes allows lower-cost alloys to be used, reducing capital expenditures.  Wet electrostatic precipitators (WESPs) […]

Developing a compliance approach for a new regulation sometimes means overlooking unintended consequences of the chosen compliance method. Preparing for compliance with the new U.S. Environmental Protection Agency (EPA) regulations on coal combustion residuals (CCR Rule), published in the Federal Register on April 17, 2015, is causing many power producers to make significant changes to […]

In a 5–4 decision announced on June 29, the U.S. Supreme Court overturned the Environmental Protection Agency’s (EPA’s) rules limiting mercury and other hazardous air pollutants released from power plants. In April 2014, the U.S. Court of Appeals for the D.C. Circuit upheld the Mercury and Air Toxics Standards (MATS), ruling in a 2–1 decision […]

A bill that would halt the Clean Power Plan’s compliance deadlines until litigation on the rule has been completed has passed the U.S. House of Representatives with a 247–180 vote.  The Ratepayer Protection Act (H.R. 2042) now goes to the Senate, where the GOP is working on a similar measure to suspend the Environmental Protection […]

Several Arizona and New Mexico–based utilities will be required to install pollution controls at the coal-fired Four Corners Power Plant to curb sulfur dioxide (SO2) and nitrogen oxide (NOx) under a settlement reached with the Environmental Protection Agency and the Justice Department.
