Current through Register Vol. 54, No. 28, July 13, 2024
(a) The owner and operator of a major
						NOx emitting facility listed in this section and subject
						to §
												129.91 (relating to control of
						major sources of NOx and VOCs) may elect to comply with
						the emission limitations of this section as an alternative to developing and
						implementing a RACT emission limitation on a case-by-case basis.
(b) The owner and operator shall develop and
						implement the following presumptive RACT emission limitations:
(1) For a coal-fired combustion unit with a
						rated heat input equal to or greater than 100 million Btu/hour, presumptive
						RACT shall be the installation and operation of low NOx
						burners with separate overfire air.
(2) For a combustion unit with a rated heat
						input equal to or greater than 20 million Btu/hour and less than 50 million
						Btu/hour presumptive RACT shall be the performance of an annual adjustment or
						tuneup on the combustion process. This adjustment shall include, at a minimum,
						the following:
(i) Inspection, adjustment,
						cleaning or replacement of fuel-burning equipment, including the burners and
						moving parts necessary for proper operation as specified by the
						manufacturer.
(ii) Inspection of
						the flame pattern or characteristics and adjustments necessary to minimize
						total emissions of NOx, and to the extent practicable
						minimize emissions of CO.
(iii)
						Inspection of the air-to-fuel ratio control system and adjustments necessary to
						ensure proper calibration and operation as specified by the
						manufacturer.
(3) For
						combustion units subject to paragraph (2), the owner and operator of the
						adjusted equipment shall record each adjustment conducted under the procedures
						in paragraph (2) in a permanently bound log book or other method approved by
						the Department. This log shall contain, at a minimum, the following
						information:
(i) The date of the tuning
						procedure.
(ii) The name of the
						service company and technicians.
(iii) The final operating rate or
						load.
(iv) The final CO and
						NOx emission rates.
(v) The final excess oxygen rate.
(vi) Other information required by the
						applicable operating permit.
(4) For oil, gas and combination oil/gas
						units subject to paragraph (2), the owner and operator shall maintain records
						including a certification from the fuel supplier of the type of fuel and for
						each shipment of distillate oils number 1 or 2, a certification that the fuel
						complies with ASTM D396-78 "Standard Specifications for Fuel Oils." For
						residual oils, minimum recordkeeping includes a certification from the fuel
						supplier of the nitrogen content of the fuel, and identification of the
						sampling method and sampling protocol.
(5) For oil and gas and combination oil/gas
						fired units subject to paragraph (2), the owner and operator shall make the
						annual adjustment in accordance with the EPA document "Combustion Efficiency
						Optimization Manual for Operators of Oil and Gas-fired Boilers," September 1983
						(EPA-340/1-83-023) or equivalent procedures approved in writing by the
						Department.
