Boiler and industrial furnace act

The Federal Register (vol. 69, no. 76, April 20, 2004) issued Proposed Rules for Existing and New Sources of HWCs. This included not only the HWIs, CKs, and LWAKs, but also for the first time the solid-fuel-fired boilers, liquid-fuel-fired boilers, and hydrochloric acid production furnaces. The boilers and HCl furnaces had been covered by the Boilers and Industrial Furnaces standards issued as Boiler and Industrial Furnace Act (BIF) in 1991. When MACT was enacted for HWCs on September 30, 1999, the BIFs were not included. The proposed standards were listed in Tables 1 and 2 of the FR of April 20, 2004. 

There are over 280 million scrap tires produced annually in the United States. Of these over 100 million are used as fuel and most of these are burnt to supplement fuel use in cement and other rotary kiln operations. The cement process is particularly convenient for tire combustion because the reinforced steel wire in the tire tread can be a source of iron for the cement chemistry. Kilns burning tires must comply with the EPA s boiler and industrial furnace act and hence are heavily regulated as a pollution source. Table 6.3 gives a typical average composition of tires supplied by the Rubber Manufacturers Association of America.
