9.6.1 The operator shall calculate and record on a daily basis the aggregated NOx emissions of furnaces which are subject to an ECP. Such records shall be kept for a period of five years. The operator shall notify the APCO of any violation of Section 9.4 within 24 hours. The notification

shall include:

9.6.1.1 name and location of the facility;

9.6.1.2 identification of furnace(s) causing the exceedances;

9.6.1.3 the cause and the expected duration of exceedances;SJVUAPCD 4354 - 17 8/17/06 9.6.1.4 calculation of actual NOx, CO and VOC emissions;

9.6.1.5 corrective actions and schedules to complete the work

.

9.6.2 The operator shall demonstrate compliance with the requirements of Section 9.4 through CEMS data or approved alternate emission monitoring methods, and source test results.

9.7 Determination of Aggregated NOx Emissions

9.7.1 The aggregated NOx emissions of a furnace battery are the NOx emissions as measured at the common stack divided by the sum of the daily glass pulled from each furnace.

9.7.2 The aggregated NOx emissions of multiple furnaces are the sum of the daily NOx emissions of each furnace divided by the sum of the daily glass pulled from each furnace.SJVUAPCD 4354 - 18 8/17/06 This page left intentionally blank.
