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). [For March only] 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, with 99% efficiency, to be installed on VE-South process and equipment emissions by end of June 2019. 2017 Baseline Emissions Percent Reduction Chemours Company - Fayetteville Works Jun-19 Air Permit No. 03735T44 Month Notes Status GenX Compound Emissions (lbs) December 31, 2018 1 Actual 0.3 January 2019 Actual 10.8 February 2019 Actual 31.3 March 2019 Actual 46.4 April 2019 Actual 10.7 May 2019 Actual 13.3 June 2019 Projected 11.3 July 2019 Projected 4.2 August 2019 Projected 10.4 September 2019 Projected 3.0 October 2019 Projected 0.2 November 2019 Projected 8.2 December 1-30, 2019 2 Projected 2.9 152.8 2,302.7 93.36% Notes: 1) Contains emissions from December 31, 2018 only 2) Contains emissions from December 1, 2019 - December 30, 2019 Assumptions: Table 2 Inventory of Emissions of GenX Compounds (Per Consent Order, Paragraph 8b) June-19 3) 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.
