NR 463.15(9)(a)(a) The owner or operator of a continuous lime injection system shall verify that lime is always free-flowing by one of the following methods: NR 463.15(9)(a)1.1. Inspecting each feed hopper or silo at least once each 8-hour period and recording the results of each inspection. If lime is found not to be free-flowing during any of the 8-hour periods, the owner or operator shall increase the frequency of inspections to at least once every 4-hour period for the next 3 days. The owner or operator may return to inspections at least once every 8-hour period if corrective action results in no further blockages of lime during the 3-day period. NR 463.15(9)(a)2.2. Subject to the approval of the department, installing, operating and maintaining a load cell, carrier gas or lime flow indicator, carrier gas pressure drop measurement system or other system to confirm that lime is free-flowing. If lime is found not to be free-flowing, the owner or operator shall promptly initiate and complete corrective action. NR 463.15(9)(a)3.3. Subject to the approval of the department, installing, operating and maintaining a device to monitor the concentration of HCl at the outlet of the fabric filter. If an increase in the concentration of HCl indicates that the lime is not free-flowing, the owner or operator shall promptly initiate and complete corrective action. NR 463.15(9)(b)(b) The owner or operator of a continuous lime injection system shall record the lime feeder setting once each day of operation. NR 463.15(9)(c)(c) An owner or operator who intermittently adds lime to a lime coated fabric filter shall obtain approval from the department for a lime addition monitoring procedure. The department may not approve a monitoring procedure unless data and information are submitted establishing that the procedure is adequate to ensure that relevant emission standards will be met on a continuous basis. NR 463.15(10)(10) Total reactive flux injection rate. The requirements of this subsection apply to the owner or operator of a group 1 furnace or in-line fluxer. The owner or operator shall meet pars. (a) to (d) or apply for approval of an alternate method under par. (e): NR 463.15(10)(a)(a) Install, calibrate, operate and maintain a device to continuously measure and record the weight of gaseous or liquid reactive flux injected to each affected source or emission unit. NR 463.15(10)(a)1.1. The monitoring system shall record the weight for each 15-minute block period, during which reactive fluxing occurs, over the same operating cycle or time period used in the performance test. NR 463.15(10)(a)2.2. The weight measurement device shall be accurate to ± 1% of the weight of the reactive component of the flux being measured. The owner or operator may apply to the department for permission to use a weight measurement device of alternative accuracy in cases where the reactive flux flow rates are so low as to make the use of a weight measurement device of ±1% impracticable. A device of alternative accuracy may not be approved unless the owner or operator provides assurance through data and information that the affected source will meet the relevant emission standards. NR 463.15(10)(a)3.3. The owner or operator shall verify the calibration of the weight measurement device in accordance with the schedule specified by the manufacturer, or if no calibration schedule is specified, at least once every 6 months. NR 463.15(10)(b)(b) Calculate and record the gaseous or liquid reactive flux injection rate (kg/Mg or lb/ton) for each operating cycle or time period used in the performance test using the procedure in s. NR 463.163 (15). NR 463.15(10)(c)(c) Record, for each 15-minute block period during each operating cycle or time period used in the performance test during which reactive fluxing occurs, the time, weight and type of flux for each addition of the following: NR 463.15(10)(d)(d) Calculate and record the total reactive flux injection rate for each operating cycle or time period used in the performance test using the procedure in s. NR 463.163 (15). NR 463.15(10)(e)(e) At their discretion, apply to the department for approval of an alternative method for monitoring and recording the total reactive flux addition rate based on monitoring the weight or quantity of reactive flux per ton of feed or charge for each operating cycle or time period used in the performance test. An alternative monitoring method may not be approved unless the owner or operator provides assurance through data and information that the affected source will meet the relevant emission standards on a continuous basis. NR 463.15(11)(11) Thermal chip dryer. The requirements of this subsection apply to the owner or operator of a thermal chip dryer with emissions controlled by an afterburner. The owner or operator shall do both of the following: NR 463.15(11)(a)(a) Record the type of materials charged to the unit for each operating cycle or time period used in the performance test. NR 463.15(12)(12) Dross-only furnace. The requirements of this subsection apply to the owner or operator of a dross-only furnace. The owner or operator shall do both of the following: NR 463.15(12)(a)(a) Record the materials charged to each unit for each operating cycle or time period used in the performance test. NR 463.15(13)(13) In-line fluxers using no reactive flux. The owner or operator of an in-line fluxer that uses no reactive flux materials shall submit a certification of compliance with the operational standard for no reactive flux materials in s. NR 463.14 (12) for each 6-month reporting period. Each certification shall contain the information in s. NR 463.18 (2) (b) 6. NR 463.15(14)(14) Sidewell group 1 furnace with add-on air pollution control devices. The requirements of this subsection apply to the owner or operator of a sidewell group 1 furnace using add-on air pollution control devices. The owner or operator shall do both of the following: NR 463.15(14)(a)(a) Record in an operating log for each charge of a sidewell furnace that the level of molten metal was above the top of the passage between the sidewell and hearth during reactive flux injection, unless the furnace hearth was also equipped with an add-on control device.
