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 July stack testing data were utilized for the period after installation. 2017 Baseline Emissions Percent Reduction Table 1 Inventory of Emissions of GenX Compounds (Per Consent Order, Paragraph 8a) November-19 Total GenX Compound Emissions (12-Month Period from October 6, 2018 through October 5, 2019) Chemours Company - Fayetteville Works Nov-19 Air Permit No. 03735T45 Month Notes Status GenX Compound Emissions (lbs) December 31, 2018 1 Actual 0.3 January 2019 Actual 10.9 February 2019 Actual 31.7 March 2019 Actual 46.7 April 2019 Actual 9.7 May 2019 Actual 10.3 June 2019 Actual 11.9 July 2019 Actual 3.1 August 2019 Actual 4.3 September 2019 Actual 3.0 October 2019 Actual 0.7 November 2019 Projected 8.5 December 1-30, 2019 2 Projected 3.2 144.2 2,302.7 93.74% Notes: 1) Contains emissions from December 31, 2018 only 2) Contains emissions from December 1, 2019 - December 30, 2019 Assumptions: 4) Unless otherwise noted, emissions are calculated using average stack test data from relevant stack testing.
