11 Schedule B Procedure to calculate and record the 10-minute average concentration of odour at the Point of Impingement and at the most impacted Sensitive Receptor(s) (a) Calculate and record one-hour average concentration of odour at the Point of Impingement and at the most impacted Sensitive Receptor(s), employing the AERMOD atmospheric dispersion model or with another atmospheric dispersion model acceptable to the Director that employs at least five (5) years of hourly local meteorological data and that can provide results reported as individual one-hour average odour concentrations. (b) Convert and record each of the one-hour average concentrations predicted over the five (5) years of hourly local meteorological data at the Point of Impingement and at the most impacted Sensitive Receptor(s) to 10-minute average concentrations using the One-Hour Average to 10- Minute Average Conversion described below. (c) Record and present the 10-minute average concentrations predicted to occur over a five (5) year period at the Point of Impingement and at the most impacted Sensitive Receptor(s) in a histogram. The histogram shall identify all predicted 10-minute average odour concentration occurrences in terms of frequency, identifying the number of occurrences over the entire range of predicted odour concentration in increments of not more than 1/10 of one odour unit. The maximum 10-minute average concentration of odour at the Sensitive Receptor(s) will be considered to be the maximum odour concentration at the most impacted Sensitive Receptor(s) that occurs and is represented in the histogram, disregarding outlying data points on the histogram as agreed to by the Director. ONE-HOUR AVERAGE TO 10-MINUTE AVERAGE CONVERSION Use the following formula to convert and record one-hour average concentrations predicted by the AERMOD atmospheric dispersion model to 10-minute average concentrations: X10min = X60min * 1.65 where X10min= 10-minute average concentration X60min= one-hour average concentration Schedule "C" PARAMETER: Opacity INSTALLATION: The continuous opacity monitor shall be installed at an accessible location where the measurements are representative of the actual opacity of the gases leaving the baghouse dust collector serving the dryer/mixer and shall meet the following design and installation specifications.: PARAMETERS Wavelength at Peak Spectral Response (nanometres, nm) SPECIFICATION Wavelength at Mean Spectral Response (nm) Detector Angle of View 5 degrees

12 5 Angle of Projection 5 degrees Range (percent of opacity) PERFORMANCE: The continuous opacity monitor shall meet the following minimum performance specifications for the following parameters. PARAMETERS 1 Span Value (percent opacity) SPECIFICATION 2 times the average normal opacity of the source 2 Calibration Error 3 percent opacity 3 Attenuator Calibration 2 percent opacity 4 Response Time (95 percent response to a step change) 10 seconds 5 Schedule for Zero and Calibration Checks daily minimum 6 Procedure for Zero and Calibration Checks: all system components checked 7 Zero Calibration Drift (24-hours) 2 percent opacity 8 Span Calibration Drift (24-hours) 2 percent opacity 8 Conditioning Test Period: 9 Operational Test Period: ³ 168 hours without corrective maintenance ³ 168 hours without corrective maintenance CALIBRATION: The monitor shall be calibrated, to ensure that it meets the drift limits specified above, during the periods of the operation of the baghouse. The results of all calibrations shall be recorded at the time of calibration. DATA RECORDER: The data recorder must be capable of registering continuously the measurement of the monitor with an accuracy of 0.5 percent of a full scale reading or better and with a time resolution of 30 seconds or better. RELIABILITY: The monitor shall be operated and maintained so that accurate data is obtained during a minimum of 90 percent of the time for each calendar quarter during the first full year of operation, and 95 percent, thereafter.
