Sources and Emissions Controls 



As discussed above, emissions from the KPC facility result primarily from two multi-fuel-fired 

 power boilers, one oil-fired package boiler, tour chemical recovery boilers, two acid plants, 

 nine digesters, bleach plant, wash plant, water treatment facility, miscellaneous storage and 

 process tanks, and associated equipment and activities These sources and the specific stacks 

 or vents through which emissions are released to the ambient environment have been approved 

 by ADEC and are subject to extensive and comprehensive monitoring and reporting 

 requirements. 



Package Boiler. KPC's oil-fired package boiler was constructed in 1988 and is rated at 1 53 

 million Btu per hour. This source was constructed after the promulgation of applicable Federal 

 New Source Performance Standards (NSPS) and is regulated primarily by EPA under the 

 regulatory standards found in 40 C F R part 60 The NSPS impose limits for sulfijr dioxide, 

 nitrogen oxides, and opacity NOx is limited to 300 Ib/NlMBtu A Dynawave Scrubber was 

 installed to ensure compliance with a requirement to remove 90 percent of sulfijr dioxide. In 

 addition, the concentration of sulfijr dioxide is limited by regulation to 500 parts per million 

 (ppm) 



The boiler has continuous emission monitors (CEMs) on the scrubber inlet which measure 

 nitrogen oxides, sulfijr dioxide, oxygen and opacity At the outlet, CEMs measure sulfijr 

 dioxide and oxygen. In the fijture, it will be a permit requirement to conduct visual readings 

 (using a "certified eye" aka Method 9) for opacity during certain maintenance procedures and 

 during startup scenarios when it is feasible to do so 



Power Boilers. The two multi-fijel boilers (power boilers) are regulated primarily by ADEC. 

 They typically bum No 6 low sulfijr fijel oil, bark, sawdust, knots, waste treatment sludge, 

 paper, used sorbent pads, and used oil The power boilers have limitations on sulfijr dioxide, 

 nitrogen oxides and opacity. The sulfijr dioxide is limited to 500 ppm Nitrogen oxides are 

 limited under a facility wide limit of 863 tons per year calculated on a monthly rolling basis. 

 This limit was established to ensure compliance with Federal Prevention of Significant 

 Deterioration (PSD) requirements 



Each power boiler is equipped with a mechanical fly ash collection device followed by an 

 electrostatic precipitator (ESP) for control of particulate emissions Each boiler has pressure 

 recovery staged combustion burners low to help control NOx burners and CEMs to monitor 

 nitrogen oxides, carixjn monoxide, sulfijr dioxide, oxygen, and opacity. 



Recovery Boilers. KPC's four recovery boilers are used to recover chemicals from the pulping 

 process as well as generate power to operate the facility Emissions from KPC's four recovery 

 boilers are sent to two separate absorption systems to collect and recycle sulfiir dioxide. The 

 reclaimed sulfijr is used in the process To control particulate emissions, the recovery boilers 

 have multi-clones as well as sbc Brinks canisters Each Brinks canister contains 28 filter 

 elements which are packed with polyester fibers that trap and control particulate emissions.
