Final Boiler and Process Heater NESHAP Released

On December 21, 2012, the Environmental Protection Agency (EPA) released air pollution rules regulating hazardous air emissions from industrial boilers and process heaters. This package of combustion rules includes a revised version of the Industrial Boiler Maximum-Achievable Control Technology standard (Boiler MACT).

The final combustion rule package addresses major and area source industrial boilers, as well as commercial and industrial solid waste incinerators (CISWI). These rules provide new emissions limits, compliance dates and important clarifications on how the rules are to be implemented. The rule package also includes guidance for defining whether non-hazardous secondary materials (NHSM) are to be considered a solid waste or a fuel, which is a critical decision for determining whether combustion of such materials must be regulated under the generally more stringent incinerator CISWI rules or the revised Boiler MACT rules.
