Current through Register Vol. 48, No. 10, October 25, 2024

Section 61-62.5.3.VI - CONTINUOUS MONITORING REQUIREMENTS

A. Monitoring

1. The owner/operator shall install, calibrate, maintain and operate monitoring devices as indicated below within one year from February 26, 1988. Required monitoring devices must meet the specifications of Section VII of this standard. Alternative site-specific methods of monitoring, other than those cited below, may be used provided prior approval from the Department is obtained. Other monitors may be required by permits as conditions warrant.

2. Specific Source Types

a. Retail Business Incinerators - None.

b. Crematory Incinerator - None.

c. Sludge Incinerator (effective June 25, 1999) - Monitoring devices if required by 40 CFR 60 Subpart O.

d. Hazardous Waste Incinerators

(i) The temperature must be continuously recorded as measured at the point of incineration.

(ii) The pressure drop across baghouses and scrubbers must be continuously measured and recorded.

(iii) The concentration of carbon monoxide in the effluent gas stream must be continuously measured and recorded.

(iv) The concentration of oxygen in the effluent gas stream must be continuously measured and recorded.

(v) The waste feed rate to the incinerator must be continuously measured and recorded.

e. Municipal Waste Combustor (effective June 25, 1999)

(i) The combustion chamber exit temperature shall be continuously measured and recorded. Sensors shall be located such that flames from the burners do not impinge on the sensors.

(ii) Pollution control performance gauges or meters as required by permit conditions.

(iii) Instruments for the continuous monitoring and recording of O₂, CO, CO₂, and opacity.

(iv) For cement kilns wishing to comply with the THC limit, instruments for the continuous monitoring and recording of THC.

(v) The Department reserves the right to require HCl monitors at any time if it is determined to be necessary.

(vi) The O₂, CO and CO₂ (and THC if applicable) monitors shall be co-located upstream of the air pollution control devices. If the applicant chooses to comply with the HCl emission limitations by meeting the percent reduction or BACT reduction requirement, the HCl monitors, when required, shall be located upstream and downstream from the air pollution control device. If the applicant chooses to monitor the two locations with a single detector, the two locations should be sampled at an interval previously approved by the Department.

(vii) The Department reserves the right to require, at a later date, the owner/operator to provide telemetering of continuous monitoring data to the Department.

f. Air Curtain Incinerator - None.

g. Commercial Incinerator (effective June 25, 1999) - The combustion chamber exit temperature shall be continuously measured and recorded. Sensors shall be located such that flames from the burners do not impinge on the sensors.

h. Industrial Incinerators - Monitoring may be required as in item d. or e. above depending on the material being incinerated or burned and source test results.

i. Industrial Boilers and Utility Boilers - Monitoring may be required as in item d. or e. above depending on the material being incinerated or burned and source test results.

j. Non-Industrial Boilers - None.

k. Industrial Furnaces - Monitoring may be required as in item d. or e. above depending on the material being incinerated or burned and source test results.

l. Non-Industrial Furnaces - None.

B. Measurement and Recording Frequencies for Continuous Monitoring Systems

1. Temperature:

Monitors subject to this requirement shall take a minimum of one measurement every 15 seconds with this data recorded at least every successive 60 seconds. The minimum data recorder resolution shall be 50 degrees F (Fahrenheit).

2. Pressure Drop:

Monitors subject to this requirement shall take a minimum of one measurement every 15 minutes with this data recorded at least every successive 15 minutes. The minimum data recorder resolution shall be 0.2 inches of H₂O (water).

3. Waste Flowmeters:

Monitors subject to this requirement shall take a minimum of one measurement every 60 seconds with this data recorded at least every successive 5 minutes. The minimum data recorder resolution shall be 5 percent of the design flow rate.

4. O₂ Monitor:

5. CO Monitor:

6. CO₂ Monitor:

7. HCl Monitor:

8. Opacity Monitor:

Monitors subject to this requirement shall complete a minimum of one cycle of sampling and analysis for each successive 10-second period and one cycle of data recording for each successive 6-minute period. The minimum data recorder resolution shall be 0.5 percent opacity.

9. THC Monitor:

Monitors subject to this requirement shall take a minimum of one measurement every 15 minutes with the data recorded at least every successive 15 minutes. The minimum data recorder resolution shall be 1 ppm.

C. Recordkeeping

1. Any owner or operator subject to any of the provisions of this standard shall maintain a file of all measurements, data and correspondence relating to continuous monitoring systems, other monitoring devices, performance testing measurements, all continuous monitoring system performance evaluations, all continuous monitoring system or monitoring device calibration checks, and adjustments and maintenance performed on these systems or devices.

2. The owner or operator of any source subject to any of the provisions of this standard shall record the daily waste(s) charge rates and hours of operation (effective June 25, 1999).

3. Copies of all records and reports required under this section shall be available for inspection during normal working hours and copies shall be furnished within 10-working days after receipt of a written request from the Department.

4. Copies of all records and reports required under this section shall be retained by the owner/operator for five years after the date on which the record was made or the report submitted.

D. Reporting and Corrective Action

1. All sources subject to the monitoring provisions of this section will be required to report quarterly all exceedances of limits specified in the source's permit and this standard. All quarterly reports must be postmarked by the 30th day following the end of each calendar quarter.

2. Any source subject to this standard must report any changes in operating or monitoring parameters and/or any equipment malfunctions which result in exceedances of the emissions limitations herein, within 24 hours after the occurrence unless otherwise approved in a Department approved malfunction plan. This report shall be made to the appropriate Regional Environmental Quality Control Office. In addition, the flow of hazardous waste fed to the combustion source must be stopped until proper operating conditions are restored.

3. For those sources not required to have a continuous emission monitor for the specified pollutant, a detailed report shall be submitted to the Department within 30 days following any exceedance of limits specified in the source's permit and/or this standard unless otherwise approved in a Department approved malfunction plan. The report shall include at a minimum all of the elements listed in Regulation Regulation 61-62.1, Section II.J.1.c.
