DAO's Comments Retarding Inventory
CO emission increased by 10% due to a 200% increase in production of vinyl ethers. S02 emission increased due to higher usage o_-
S02 in the nafion RSU process. VOC emissions were reduced by 12.6% due to the sale of the Butacite and SentryGlas facilities to
Kuraray, removing these processes from the Chemours permit. Arsenic emissions decreased by 16.2%, beryllium metal emissions
decreased by 66.7%, lead emissions decreased 53.6%, manganese emissions decreased by 12.8%, methyl chloroform emissions
decreased by 99.8%, polycyclic organic matter emissions decreased by 99.8%, and selenium emissions decreased by 86.4% due to
the boilers not firing #6 fuel oil during 2015. Ammonia emissions increased 10.4% due to somewhat higher usage of ammonia in the
wastewater treatment process. CFC-113 emissions increased by 70% due to higher production levels in the Nafion semiworks
process. Chlorine emissions increased by 31 % due to higher chlorine usage in the wastewater treatment process. Methanol
emissions decreased 12.8% due to reduction of the amount of wastewater handled during 2015. Methylene Chloride emissions
increased due to more leakage and spills from the Nafion membrane coolant systems. Sulfuric acid emissions decreased by 12.9%
due to decreased production levels in the nafion RSU process and the polymer processing aid process. Ethyl Benzene emissions
increased by 76%, ethylene glycol emissions increased by 53%, MEK emissions increased by 75.8%, toluene emissions increased b3
34.2%, and xylene emissions increased by 53.4% due to higher paint usage by the maintenance department. Formaldehyde
emissions showed an apparent emissions increase of 273%, but it appears there was an error in the input of the emissions for 2014
that accounts for this increase. Correction made to S02 emissions for Nafion RSU process. Emissions were incorrectly entered as
5.3 tons, but actual calculated emissions were 5.3 pounds.
