3) Contains emissions from October 1, 2019 - October 5, 2019

Total GenX Compound Emissions
(12-Month Period from October 6, 2018
through October 5, 2019)
4) Unless otherwise noted, emissions are calculated using average stack test data
from relevant stack testing.
3) [For March only] Emission rate for when the ABR only was operating was
determined by subtracting the 230 kg/hr ABR on and ABR off runs from the
February 2019 stack testing. Stack testing following the permeator tie-in (March
2019) was not utilized for determining ABR only emissions since those specific
conditions were not tested independently. Therefore, emissions rates after the
permeator was tied in to the scrubber 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 stack testing), and 95.1% for Carbon
Bed (from March 2019 stack testing).
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, 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 became operational on VE-South process and equipment emissions
on June 29, 2019. Emissions from stack testing data (post carbon bed install) will
be utilized once results are received. Assumed control efficiency of 99% for these
calculations.
