CEP: February 2014 The Boiler MACT regulation requires owners of industrial, commercial, and institutional boilers to apply maximum achievable control technology (MACT) to limit emissions of hazardous air pollutants, specifically carbon monoxide, hydrogen chloride, mercury, and either particulate matter or total selected metals. The rule provides compliance options that include pollution-abatement equipment, work practices, and energy efficiency improvements. An energy management and reporting system (EMRS) can be part of a plant's compliance strategy. This month's cover feature outlines an approach to EMRS implementation for work practices, advanced controls, and automated reporting systems that sources can use to comply with the regulation. Other topics in this issue include: take the FUN out of process safety; distillation column revamps; and Argentina's chemicals industry.
