Sec.  63.1452  What are my monitoring requirements?



    (a) Copper converter department capture systems. For each operating 

limit established under your capture system operation and maintenance 

plan, you must install, operate, and maintain an appropriate monitoring 

device according the requirements in paragraphs (a)(1) though (6) of 

this section to measure and record the operating limit value or setting 

at all times the copper converter department capture system is operating 

during batch copper converter blowing. Dampers that are manually set and 

remain in the same position at all times the capture system is operating 

are exempted from the requirements of this paragraph (a).

    (1) Install the monitoring device, associated sensor(s), and 

recording equipment according to the manufacturers' specifications. 

Locate the sensor(s) used for monitoring in or as close to a position 

that provides a representative measurement of the parameter being 

monitored.

    (2) If a flow measurement device is used to monitor the operating 

limit parameter, you must meet the requirements in paragraph (a)(2)(i) 

through (iv) of this section.

    (i) Locate the flow sensor and other necessary equipment such as 

straightening vanes in a position that provides a representative flow.

    (ii) Use a flow sensor with a minimum tolerance of 2 percent of the 

flow rate.

    (iii) Reduce swirling flow or abnormal velocity distributions due to 

upstream and downstream disturbances.



[[Page 41]]



    (iv) Conduct a flow sensor calibration check at least semiannually.

    (3) If a pressure measurement device is used to monitor the 

operating limit parameter, you must meet the requirements in paragraph 

(a)(3)(i) through (v) of this section.

    (i) Locate the pressure sensor(s) in or as close to a position that 

provides a representative measurement of the pressure.

    (ii) Minimize or eliminate pulsating pressure, vibration, and 

internal and external corrosion.

    (iii) Use a gauge with a minimum tolerance of 0.5 inch of water or a 

transducer with a minimum tolerance of 1 percent of the pressure range.

    (iv) Check pressure tap pluggage daily.

    (v) Using a manometer, check gauge calibration quarterly and 

transducer calibration monthly.

    (4) Conduct calibration and validation checks any time the sensor 

exceeds the manufacturer's specifications or you install a new sensor.

    (5) At least monthly, inspect all components for integrity, all 

electrical connections for continuity, and all mechanical connections 

for leakage.

    (6) Record the results of each inspection, calibration, and 

validation check.

    (b) Baghouses. For each baghouse subject to the operating limit in 

Sec.  63.1444(f) or Sec.  63.1446(c) for the bag leak detection system 

alarm, you must at all times monitor the relative change in particulate 

matter loadings using a bag leak detection system according to the 

requirements in paragraph (b)(1) of this section and conduct regular 

inspections according to the requirements in paragraph (b)(2) of this 

section.

    (1) You must install, operate, and maintain each bag leak detection 

system according to the requirements in paragraphs (b)(1)(i) through 

(vii) of this section.

    (i) The system must be certified by the manufacturer to be capable 

of detecting emissions of particulate matter at concentrations of 10 

milligrams per actual cubic meter (0.0044 grains per actual cubic foot) 

or less.

    (ii) The system must provide output of relative changes in 

particulate matter loadings.

    (iii) The system must be equipped with an alarm that will sound when 

an increase in relative particulate loadings is detected over a preset 

level. The alarm must be located such that it can be heard by the 

appropriate plant personnel.

    (iv) Each system that works based on the triboelectric effect must 

be installed, operated, and maintained in a manner consistent with the 

guidance document, ``Fabric Filter Bag Leak Detection Guidance,'' EPA-

454/R-98-015, September 1997. You may obtain a copy of this guidance 

document by contacting the National Technical Information Service (NTIS) 

at 800-553-6847. You may install, operate, and maintain other types of 

bag leak detection systems in a manner consistent with the 

manufacturer's written specifications and recommendations.

    (v) To make the initial adjustment of the system, establish the 

baseline output by adjusting the sensitivity (range) and the averaging 

period of the device. Then, establish the alarm set points and the alarm 

delay time.

    (vi) Following the initial adjustment, do not adjust the sensitivity 

or range, averaging period, alarm set points, or alarm delay time, 

except as detailed in your operation and maintenance plan. Do not 

increase the sensitivity by more than 100 percent or decrease the 

sensitivity by more than 50 percent over a 365-day period unless a 

responsible official certifies, in writing, that the baghouse has been 

inspected and found to be in good operating condition.

    (vii) Where multiple detectors are required, the system's 

instrumentation and alarm may be shared among detectors.

    (2) You must conduct baghouse inspections at their specified 

frequencies according to the requirements in paragraphs (b)(2)(i) 

through (viii) of this section.

    (i) Monitor the pressure drop across each baghouse cell each day to 

ensure pressure drop is within the normal operating range identified in 

the manual.

    (ii) Confirm that dust is being removed from hoppers through weekly 

visual inspections or other means of ensuring the proper functioning of 

removal mechanisms.



[[Page 42]]



    (iii) Check the compressed air supply for pulse-jet baghouses each 

day.

    (iv) Monitor cleaning cycles to ensure proper operation using an 

appropriate methodology.

    (v) Check bag cleaning mechanisms for proper functioning through 

monthly visual inspection or equivalent means.

    (vi) 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.

    (vii) Confirm the physical integrity of the baghouse through 

quarterly visual inspections of the baghouse interior for air leaks.

    (viii) Inspect fans for wear, material buildup, and corrosion 

through quarterly visual inspections, vibration detectors, or equivalent 

means.

    (c) Venturi wet scrubbers. For each venturi wet scrubber subject to 

the operating limits for pressure drop and scrubber water flow rate in 

Sec.  63.1444(g) or Sec.  63.1446(d), you must at all times monitor the 

hourly average pressure drop and water flow rate using a CPMS. You must 

install, operate, and maintain each CPMS according to the requirements 

in paragraphs (c)(1) and (2) of this section.

    (1) For the pressure drop CPMS, you must meet the requirements in 

paragraphs (c)(1)(i) through (vi) of this section.

    (i) Locate the pressure sensor(s) in or as close to a position that 

provides a representative measurement of the pressure and that minimizes 

or eliminates pulsating pressure, vibration, and internal and external 

corrosion.

    (ii) Use a gauge with a minimum measurement sensitivity of 0.5 inch 

of water or a transducer with a minimum measurement sensitivity of 1 

percent of the pressure range.

    (iii) Check the pressure tap for pluggage daily.

    (iv) Using a manometer, check gauge calibration quarterly and 

transducer calibration monthly.

    (v) Conduct calibration checks any time the sensor exceeds the 

manufacturer's specified maximum operating pressure range, or install a 

new pressure sensor.

    (vi) At least monthly, inspect all components for integrity, all 

electrical connections for continuity, and all mechanical connections 

for leakage.

    (2) For the scrubber water flow rate CPMS, you must meet the 

requirements in paragraphs (c)(2)(i) through (iv) of this section.

    (i) Locate the flow sensor and other necessary equipment in a 

position that provides a representative flow and that reduces swirling 

flow or abnormal velocity distributions due to upstream and downstream 

disturbances.

    (ii) Use a flow sensor with a minimum measurement sensitivity of 2 

percent of the flow rate.

    (iii) Conduct a flow sensor calibration check at least semiannually 

according to the manufacturer's instructions.

    (iv) At least monthly, inspect all components for integrity, all 

electrical connections for continuity, and all mechanical connections 

for leakage.

    (d) Other control devices. For each control device other than a 

baghouse or venturi wet scrubber subject to the operating limits for 

appropriate parameters in Sec. Sec.  63.1444(h) or 63.1446(e), you must 

at all times monitor each of your selected parameters using an 

appropriate CPMS. You must install, operate, and maintain each CPMS 

according to the equipment manufacturer's specifications and the 

requirements in paragraphs (d)(1) though (5) of this section.

    (1) Locate the sensor(s) used for monitoring in or as close to a 

position that provides a representative measurement of the parameter 

being monitored.

    (2) Determine the hourly average of all recorded readings.

    (3) Conduct calibration and validation checks any time the sensor 

exceeds the manufacturer's specifications or you install a new sensor.

    (4) At least monthly, inspect all components for integrity, all 

electrical connections for continuity, and all mechanical connections 

for leakage.

    (5) Record the results of each inspection, calibration, and 

validation check.

    (e) Except for monitoring malfunctions, associated repairs, and 

required quality assurance or control activities



[[Page 43]]



(including as applicable, calibration checks and required zero and span 

adjustments), you must monitor continuously (or collect data at all 

required intervals) at all times an affected source is operating.

    (f) You may not use data recorded during monitoring malfunctions, 

associated repairs, and required quality assurance or control activities 

in data averages and calculations used to report emission or operating 

levels or to fulfill a minimum data availability requirement, if 

applicable. You must use all the data collected during all other periods 

in assessing compliance.

    (g) A monitoring malfunction is any sudden, infrequent, not 

reasonably preventable failure of the monitor to provide valid data. 

Monitoring failures that are caused in part by poor maintenance or 

careless operation are not malfunctions.
