NR 440.445(5)(b)(b) Except as provided under 40 CFR 60.274a(e), the owner or operator subject to the provisions of this section shall check and record on a once-per-shift basis the furnace static pressure (if a DEC system is in use, and a furnace static pressure gauge is installed according to par. (f)) and either: check and record the control system fan motor amperes and damper position on a once-per-shift basis; install, calibrate and maintain a monitoring device that continuously records the volumetric flow rate through each separately ducted hood, or install, calibrate and maintain a monitoring device that continuously records the volumetric flow rate at the control device inlet and check and record damper positions on a once-per-shift basis. The monitoring device may be installed in any appropriate location in the exhaust duct such that reproducible flow rate monitoring will result. The flow rate monitoring device shall have an accuracy of ± 10% over its normal operating range and shall be calibrated according to the manufacturer’s instructions. The department may require the owner or operator to demonstrate the accuracy of the monitoring device relative to Methods 1 and 2 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1). NR 440.445(5)(c)(c) When the owner or operator of an affected facility is required to demonstrate compliance with the standards under sub. (3) (a) 3., and at any other time that the department may require either: the control system fan motor amperes and all damper positions, the volumetric flow rate through each separately ducted hood, or the volumetric flow rate at the control device inlet and all damper positions shall be determined during all periods in which a hood is operated for the purpose of capturing emissions from the affected facility subject to par. (b). The owner or operator may petition the department for reestablishment of these parameters whenever the owner or operator can demonstrate to the department’s satisfaction that the affected facility operating conditions upon which the parameters were previously established are no longer applicable. The values of these parameters as determined during the most recent demonstration of compliance shall be maintained at the appropriate level for each applicable period. Operation at other than baseline values may be subject to the requirements of sub. (7) (c). NR 440.445(5)(d)(d) Except as provided under 40 CFR 60.274a (e), the owner or operator shall perform monthly operational status inspections of the equipment that is important to the performance of the total capture system, that is, pressure sensors, dampers and damper switches. This inspection shall include observations of the physical appearance of the equipment such as presence of holes in ductwork or hoods, flow constrictions caused by dents or accumulated dust in ductwork and fan erosion. Any deficiencies shall be noted and proper maintenance performed.

NR 440.445(5)(f)(f) Except as provided for under 40 CFR 60.274a (e), if emissions during any phase of the heat time are controlled by the use of a DEC system the owner or operator shall install, calibrate and maintain a monitoring device that allows the pressure in the free space inside EAF to be monitored. The pressure shall be recorded as 15-minute integrated averages. The monitoring device may be installed in any appropriate location in the EAF or DEC duct prior to the introduction of ambient air such that reproducible results will be obtained. The pressure monitoring device shall have an accuracy of ±5mm of water gauge over its normal operating range and shall be calibrated according to the manufacturer’s instruction.

(f). The owner or operator may petition the department for reestablishment of the 15-minute integrated average of the pressure whenever the owner or operator can demonstrate to the department’s satisfaction that the EAF operating conditions upon which the pressures were previously established are no longer applicable. The pressure determined during the most recent demonstration of compliance shall be maintained at all times when the EAF is operating in a meltdown and refining period. Operation at higher pressures may be considered by the department to be unacceptable operation and maintenance of the affected facility.
