Post-Project Potential to Emit(PE2) The engine and the flare will not run simultaneously, so to determine the worst-case operating scenario it is first necessary to calculate the hourly emissions for each unit.

However, NO., CO, and VOC emissions from the flare are expected to be greater than from the engine. Therefore, daily and annual potential emissions will be calculated based on full-time operation of the engine, except for NO., CO, and VOC,for which daily and annual emissions will assume the Mare operates to its permit limit. Permit conditions will be included to limit flare operation to 3 hours per week and 156 hours per yeae.The engine will be presumed to operate for all of the remaining 7,644 hr/yr. : s The applicant states that the engine will be derated to 700 bhp by the syngas flow rate.A condition limiting the x"as flow to 45,058 scflhr will be used to ensure the derating remains valid. ; (45,056 scflhr)x(131 Btulscf)x(1 MMbtul1,000,000 Btu)=5.9 MMBtu/hr Applicant states the flare will operate no more than 3 hours per week.The District will assume those 3 hours could come in a single day, and(3 hNwk)x(52 wk/yr)=156 hr/yr. 10
