Notes:
1) Contains emissions from October 6, 2018 - October 31, 20182) Contains summation of emissions from December 1 - 30, 2018 and December 31, 20183) Contains emissions from October 1, 2019 - October 5, 2019
Assumptions:
1) Emission rates for PPVE campaign runs determined using the following for theFeb/March campaign: 52.4% operating time ABR is on, 2.7% burnout, and 44.9%
ABR is off. And the following for Dec 20-30, 2018 PPVE Campaign: 38.2%
operating time ABR is on, 2.1% burnout, and 59.7% ABR is off.
2) Carbon bed, with 99% efficiency, to be installed on VE-South process andequipment emissions by end of June 2019.

3) Emission rate for when the ABR only was operating was determined bysubtracting the 230 kg/hr ABR on and ABR off runs from the February 2019 stacktesting. Stack testing following the permeator tie-in (March 2019) was not utilizedfor determining ABR only emissions since those specific conditions were not tested
independently. Therefore, emissions rates after the permeator was tied in to thescrubber were calculated using the following control efficiencies: 99.1% for Division
Scrubber (obtained from acid fluoride testing conducted by Entec Services in 2013),
45% for Secondary Scrubber (most conservative efficiency from the Dec 2018 stacktesting), and 95.1% for Carbon Bed (from March 2019 stack testing).
