Industrial Boiler/Process Heater/RICE 

MACT 
Industrial Boiler/Process Heater/RICE MACT

The Environmental Protection Agency (EPA) issued final rules to substantially reduce emissions of

toxic air pollutants from industrial, commercial and institutional boilers, process heaters and from

stationary reciprocating internal combustion engines (RICE). These rules reduce emissions of a

number of toxic air pollutants, including hydrogen chloride, manganese, lead, arsenic and mercury

by 2009. This rule also reduces emissions of sulfur dioxide and particulate matter in conjunction

with the toxic air pollutant reductions. The applied Maximum Achievable Control Technology

(MACT) control efficiencies were 4 percent for SO2 and 40 percent for PM10 and PM2.5. However,

EPA’s industrial boiler MACT rules were vacated on June 8, 2007. The emissions reductions that

were modeled to account for the industrial boiler MACT were 1,343.5 tons/year of SO2, 879.4

tons/year of PM2.5, and 1,304.2 tons/year of PM10 [see Tables 1-3]. These reductions are

insignificantly small (0.69% for SO2, 0.39% for PM2.5, and 0.13% for PM10) compared to the

statewide totals (193,665.5 tons/year SO2; 225,104.5 tons/year PM2.5; and 1,002,873.2 tons/year

PM10) and should not impact the conclusions made in the SIP. If another VISTAS “best and final”

modeling run is performed, it will remove control assumptions solely due to this MACT rule.
