- (a)For each baghouse applied to pushing emissions from a coke oven battery, you must at all times monitor the relative change in particulate matter loadings using a bag leak detection system according to the requirements in § 63.7331(a) and conduct inspections at their specified frequency according to the requirements in paragraphs (a)(1) through (8) of this section.
- (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;
- (2)Confirm that dust is being removed from hoppers through weekly visual inspections or equivalent means of ensuring the proper functioning of removal mechanisms;
- (3)Check the compressed air supply for pulse-jet baghouses each day;
- (4)Monitor cleaning cycles to ensure proper operation using an appropriate methodology;
- (5)Check bag cleaning mechanisms for proper functioning through monthly visual inspection or equivalent means;
- (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 laying on their sides. You do not have to make this check for shaker-type baghouses using self-tensioning (spring-loaded) devices;
- (7)Confirm the physical integrity of the baghouse through quarterly visual inspections of the baghouse interior for air leaks; and
- (8)Inspect fans for wear, material buildup, and corrosion through quarterly visual inspections, vibration detectors, or equivalent means.
- (b)For each venturi scrubber applied to pushing emissions, you must at all times monitor the pressure drop and water flow rate using a CPMS according to the requirements in § 63.7331(e).
- (c)For each hot water scrubber applied to pushing emissions, you must at all times monitor the water pressure and temperature using a CPMS according to the requirements in § 63.7331(f).
- (d)For each capture system applied to pushing emissions, you must at all times monitor the volumetric flow rate according to the requirements in § 63.7331(g), the fan motor amperes according to the requirements in § 63.7331(h), or the static pressure or the fan RPM according to the requirements in § 63.7331(i).
- (e)For each by-product coke oven battery, you must monitor at all times the opacity of emissions exiting each stack using a COMS according to the requirements in § 63.7331(j).
- (f)For each multicyclone applied to pushing emissions, you must monitor at all times the pressure drop using a CPMS according to the requirements in § 63.7331(k).
