The availability of long-term hourly continuous emission monitoring (CEM) data has enabled perhaps the most comprehensive and definitive assessment ever to be conducted on the performance capabilities of a retrofit NO{sub x} control technology. The study was undertaken pursuant to Section 407(b)(2) of the Clean Air Act Amendments, which grants discretionary power to the EPA Administrator to revise the applicable NO{sub x} emission limitations for Group 1 boilers {open_quotes}to be more stringent if the Administrator determines that more effective low NO{sub x} burner technology is available.{close_quotes} Group 1 boilers are existing coal-fired dry-bottom wall-fired boilers (other than cell burners) and tangentially fired boilers; any revised emission limitations would apply only to units affected in Phase II of the Acid Rain Program, beginning January 1, 2000. The Phase II affected utility boiler population in 2000 will consist of about 580 boilers, with approximately equal numbers in the two boiler categories. This landmark assessment used hundreds of thousands of hours of quality assured CEM data, measured and recorded by NO{sub x} CEM systems (CEMS) certified according to 40 CFR part 75 (Acid Rain Program Rule). The exceptional quality and length of the dataset allowed in-depth quantitative analyses on the measured performance of low-NO{sub x} burners (LNBs) to be conducted, including compiling a representative database of wall-fired and tangentially fired boilers and developing and testing alternative methods for projecting Phase II emissions.
