Industrial Boiler MACT - Implementation • MACT Compliance will require a “system solution” that includes the fuel, boiler, existing AQCS equipment, CEMS, and reporting • Available space • Age of equipment • Other local regulations still apply, i.e. SO2 & NOx • What are the final emission limits going to be? • The large volume of environmental legislation in the pipeline requires that you start planning your compliance strategy
