EA = 0.02[SIGMA] EPV1 + [SIGMA] EPV2 + 0.05[SIGMA] ES1 + [SIGMA] ES2 + 0.02[SIGMA] ETR1 + [SIGMA] ETR2 + [SIGMA] EWW1C + [SIGMA] EWW2
where:
EA = Emission rate, megagrams per year, allowed for the source.
0.02[SIGMA] EPV1 = Sum of the residual emissions, megagrams per year, from all Group 1 process vents, as defined in § 63.111 of this subpart.
[SIGMA] EPV2 = Sum of the emissions, megagrams per year, from all Group 2 process vents as defined in § 63.111 of this subpart.
0.05[SIGMA] ES1 = Sum of the residual emissions, megagrams per year, from all Group 1 storage vessels, as defined in § 63.111 of this subpart.
[SIGMA] ES2 = Sum of the emissions, megagrams per year, from all Group 2 storage vessels, as defined in § 63.111 of this subpart.
0.02[SIGMA] ETR1 = Sum of the residual emissions, megagrams per year, from all Group 1 transfer racks, as defined in § 63.111 of this subpart.
[SIGMA] ETR2 = Sum of the emissions, megagrams per year, from all Group 2 transfer racks, as defined in § 63.111 of this subpart.
[SIGMA] EWW1C = Sum of the residual emissions from all Group 1 wastewater streams, as defined in § 63.111 of this subpart. This term is calculated for each Group 1 stream according to the equation for EWW1C in § 63.150(g)(5)(i) of this subpart.
[SIGMA] EWW2 = Sum of emissions from all Group 2 wastewater streams, as defined in § 63.111 of this subpart.
The emissions level represented by this equation is dependent on the collection of emission points in the source. The level is not fixed and can change as the emissions from each emission point change or as the number of emission points in the source changes.
