NR 463.26 NR 463.26 Continuous compliance requirements.

NR 463.26(1) (1) What are my monitoring requirements?

NR 463.26(1)(a) (a) For each capture system subject to an operating limit in s. NR 463.23 (1) (b) 1., you shall install, operate and maintain a CPMS according to the requirements in sub. (2) (a) and both of the following requirements, as applicable:

NR 463.26(1)(a)1. 1. If you use a flow measurement device to monitor the operating limit parameter, you shall at all times monitor the hourly average rate.

NR 463.26 Note Note: For example, the hourly average actual volumetric flow rate through each separately ducted hood or the average hourly total volumetric flow rate at the inlet to the control device.

NR 463.26(1)(a)2. 2. For dampers that are not manually set and remain in the same position, you shall make a visual check at least once every 24 hours to verify that each damper for the capture system is in the same position as during the initial performance test. Dampers that are manually set and remain in the same position are exempt from the requirement to install and operate a CPMS.

NR 463.26(1)(b) (b) For each negative pressure baghouse or positive pressure baghouse equipped with a stack that is applied to meet any PM or total metal HAP emissions limitation in this subchapter, you shall at all times monitor the relative change in PM loadings using a bag leak detection system according to the requirements in sub. (2) (b) and do all of the following:

NR 463.26(1)(b)1. 1. Monitor the pressure drop across each baghouse cell each day to ensure pressure drop is within the normal operating range identified in the manual.

NR 463.26(1)(b)2. 2. Confirm that dust is being removed from hoppers through weekly visual inspections or other means of ensuring the proper functioning of removal mechanisms.

NR 463.26(1)(b)3. 3. Check the compressed air supply for pulse-jet baghouses each day.

NR 463.26(1)(b)4. 4. Monitor cleaning cycles to ensure proper operation using an appropriate methodology.

NR 463.26(1)(b)5. 5. Check bag cleaning mechanisms for proper functioning through monthly visual inspection or equivalent means.

NR 463.26(1)(b)6. 6. Make monthly visual checks of bag tension on reverse air and shaker-type baghouses to ensure that bags are not kinked, kneed or bent, or lying on their sides. You do not have to make this check for shaker-type baghouses using self-tensioning, spring-loaded, devices.

NR 463.26(1)(b)7. 7. Confirm the physical integrity of the baghouse through quarterly visual inspections of the baghouse interior for air leaks.

NR 463.26(1)(b)8. 8. Inspect fans for wear, material buildup and corrosion through quarterly visual inspections, vibration detectors or equivalent means.

NR 463.26(1)(c) (c) For each wet scrubber subject to the operating limits in s. NR 463.23 (1) (b) 2., you shall at all times monitor the 3-hour average pressure drop and scrubber water flow rate using CPMS according to the requirements in sub. (2) (c).
