Annual emissions = [SIGMA] Daily emissions within the calendar year.
Daily emissions = [SIGMA] 3-hour emissions within a calendar day.
Exclusive of the above definition, an hourly CEMS average may be determined with two (2) valid and complete 15-minute data blocks, for two (2) of the 24 hours in any calendar day. A complete 15-minute data block for each CEMS shall have a minimum of one (1) data point value; however, each CEMS shall be operated such that all valid data points acquired in any 15-minute block shall be used to determine the 15-minute block's reported concentration and flow rate.
3 hour emissions = Hourly emissions within the 3-hour period.
The quarterly report shall be certified for accuracy in writing by a responsible CHS Inc. official. The quarterly report shall consist of both a comprehensive electronic-magnetic report and a written hard copy data summary report.
The quarterly report shall be certified for accuracy in writing by a responsible ConocoPhillips official. The quarterly report shall consist of both a comprehensive electronic-magnetic report and a written hard copy data summary report.
Equation 1: EH = K * CH * QH
Where:
EH = Refinery fuel gas combustion hourly emissions in pounds per hour, rounded to the nearest tenth of a pound;
K= 1.688 * 10-7 in (pounds/standard cubic feet (SCF))/parts per million (ppm);
CH = Hourly refinery fuel gas H2S concentration in ppm determined by the length-of-stain detector tube method as required by paragraph (f)(3)(ii)(B) of this section; and
QH = actual fuel gas firing rate in standard cubic feet per hour (SCFH), as measured by the monitor required by section 6(B)(8) of ExxonMobil's 1998 exhibit.
Equation 2: (Refinery fuel gas combustion 3-hour emissions) = (Hourly emissions within the 3-hour period as determined by equation 1).
Equation 3: (Refinery fuel gas combustion daily emissions) = (3-hour emissions within the day as determined by equation 2).
The quarterly report shall be certified for accuracy in writing by a responsible ExxonMobil official. The quarterly report shall consist of both a comprehensive electronic-magnetic report and a written hard copy data summary report.
The quarterly report shall be certified for accuracy in writing by a responsible MSCC official. The quarterly report shall consist of both a comprehensive electronic-magnetic report and a written hard copy data summary report.
If the water seal monitoring devices indicate that there is no flow going to the flare, yet the continuous flow monitor is indicating flow, the presumption will be that no flow is going to the flare.
