Sec.  63.1447  What are my operation and maintenance requirements?



    (a) As required by Sec.  63.6(e)(1)(i), you must always operate and 

maintain your affected source, including air pollution control and 

monitoring equipment, in a manner consistent with good air pollution 

control practices for minimizing emissions at least to the levels 

required by this subpart.

    (b) You must prepare and operate at all times according to a written 

operation and maintenance plan for each capture system and control 

device subject to standards in Sec.  63.1444 or Sec.  63.1446. The plan 

must address the requirements in paragraphs (b)(1) through (3) of this 

section as applicable to the capture system or control device.

    (1) Preventative maintenance. You must perform preventative 

maintenance for each capture system and control device according to 

written procedures specified in your operation and maintenance plan. The 

procedures must include a preventative maintenance schedule that is 

consistent with the manufacturer's instructions for routine and long-

term maintenance.

    (2) Capture system inspections. You must conduct monthly inspections 

of the equipment components of the capture system that can affect the 

performance of the system to collect the gases and fumes emitted from 

the affected source (e.g., hoods, exposed ductwork, dampers, fans) 

according to written procedures specified in your operation and 

maintenance plan. The inspection procedure must include the requirements 

in paragraphs (b)(2)(i) through (iii) of this section as applicable to 

the capture system or control device.

    (i) Observations of the physical appearance of the equipment to 

confirm the physical integrity of the equipment (e.g., verify by visual 

inspection no holes in ductwork or hoods, no flow constrictions caused 

by dents, or accumulated dust in ductwork).

    (ii) Inspection, and if necessary testing, of equipment components 

to confirm that the component is operating as intended (e.g., verify by 

appropriate measures that flow or pressure sensors, damper plates, 

automated damper switches and motors are operating according to 

manufacture or engineering design specifications).

    (iii) In the event that a defective or damaged component is detected 

during an inspection, you must initiate corrective action according to 

written procedures specified in your operation and maintenance plan to 

correct the defect or deficiency as soon as practicable.

    (3) Copper converter department capture system operating limits. You 

must establish, according to the requirements in paragraph (b)(3)(i) 

through (iii) of this section, operating limits for the capture system 

that are representative and reliable indicators of the performance of 

capture system when it is used to collect the process off-gas vented 

from batch copper converters during blowing.

    (i) Select operating limit parameters appropriate for the capture 

system design that are representative and reliable indicators of the 

performance of the capture system when it is used to collect the process 

off-gas vented from batch copper converters during blowing. At a 

minimum, you must use appropriate operating limit parameters that 

indicate the level of the ventilation draft and the damper position 

settings for the capture system when operating to collect the process 

off-gas from the batch copper converters during blowing. Appropriate 

operating limit parameters for ventilation draft include, but are not 

limited to, volumetric flow rate through each separately ducted hood, 

total volumetric flow rate at the inlet to control device to which the 

capture system is vented, fan motor amperage, or static pressure.

Any parameter for damper position setting may be used that indicates the 

duct damper position relative to the fully open setting.

    (ii) For each operating limit parameter selected in paragraph 

(b)(3)(i) of this section, designate the value or setting for the 

parameter at which the capture system operates during batch copper 

converter blowing. If your blister copper production operations allow 

for more than one batch copper converter to be operating simultaneously 

in the blowing mode, designate the value or setting for the parameter at 

which the capture system operates during each possible batch copper 

converter blowing configuration that you may operate at your smelter 

(i.e., the operating limits with one converter blowing, with two 

converters blowing, with three converters blowing, as applicable to your 

smelter).

    (iii) Include documentation in the plan to support your selection of 

the operating limits established for the capture system. This 

documentation must include a description of the capture system design, a 

description of the capture system operation during blister copper 

production, a description of each selected operating limit parameter, a 

rationale for why you chose the parameter, a description of the method 

used to monitor the parameter according to the requirements in Sec.  

63.1452(a), and the data used to set the value or setting for the 

parameter for each of your batch copper converter configurations.

    (4) Baghouse leak detection corrective actions. In the event a bag 

leak detection system alarm is triggered, you must initiate corrective 

action according to written procedures specified in your operation and 

maintenance plan to determine the cause of the alarm within 1 hour of 

the alarm, initiate corrective action to correct the cause of the 

problem within 24 hours of the alarm, and complete the corrective action 

as soon as practicable. Corrective actions may include, but are not 

limited to, the activities listed in paragraphs (b)(3)(i) through (vi) 

of this section.

    (i) Inspecting the baghouse for air leaks, torn or broken bags or 

filter media, or any other condition that may cause an increase in 

emissions.

    (ii) Sealing off defective bags or filter media.

    (iii) Replacing defective bags or filter media or otherwise 

repairing the control device.

    (iv) Sealing off a defective baghouse compartment.

    (v) Cleaning the bag leak detection system probe, or otherwise 

repair the bag leak detection system.

    (vi) Shutting down the process producing the particulate emissions.
