Assumptions:

1) Emission rates for PPVE campaign runs determined using the following for
the Feb/March campaign: 52.4% operating time ABR is on, 2.7% burnout, and44.9% 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 became operational on VE-South process and equipment
emissions on June 29, 2019. Emissions from July stack testing data were
utilized for the period after installation.

3) [For March only] Emission rate for when the ABR only was operating wasdetermined by subtracting the 230 kg/hr ABR on and ABR off runs from theFebruary 2019 stack testing. Stack testing following the permeator tie-in(March 2019) was not utilized for determining ABR only emissions since thosespecific conditions were not tested independently. Therefore, emissions rates
after the permeator was tied in to the scrubber were calculated using thefollowing control efficiencies: 99.1% for Division Scrubber (obtained from acidfluoride testing conducted by Entec Services in 2013), 45% for Secondary
Scrubber (most conservative efficiency from the Dec 2018 stack testing), and95.1% for Carbon Bed (from March 2019 stack testing).
4) Unless otherwise noted, emissions are calculated using average stack test
data from relevant stack testing.
