The Environmental Protection Agency released final rules December 20 that revise air emissions limits for boilers and incinerators but allow the industry extra time to comply. The new rules, which the agency says retain many of the benefits of the original 2011 standard, are expected to prevent 8,100 premature deaths and 5,100 heart attacks by reducing emissions of mercury, particulate matter, and other pollutants. The rules require that major source boilers be in compliance by 2016. The solid waste incinerator rule revises new source performance standards and emissions guidelines while also adjusting emissions limits for dioxins and mercury. The rule also eliminates the oxygen correction requirements for carbon monoxide emissions limits during startup and shutdown and mandates constant parametric monitoring of particulate matter from waste-burning kilns and large energy recovery units.
