Capture Detector (GC/ECD) at the US and European sites and by High Performance

Liquid Chromatography (HPLC) method at our Japan site. The Limit of Detection

(LOD) for the GC/ED method is 1 ppm. The LOD for the HPLC method is 3 ppm at this

Methods usedwere as follows: LC/MS/MS - PFOA; GC/MS - all others.Values were obtained by measuring individual products, obtaining the impurity levels in ppm, and then calculating the actual pounds of impurities bymultiplying the pounds made times the ppm of impurities. These are the values reported above. If a value was determined to be <LOQ, we used thestandard EPA convention of 1/2 LOQ as the measurement for the yearly pounds calculation. The general methods used for the analyses reportedhere have been published in the following article:Larsen, B.S.; Stchur, P.; Szostek, B.; Bachmura, S.F.; Rowand, R.C.; Prickett, K.B.; Korzeniowski,S.H.; Buck, R.C.

In general the LOQ was 2 ppm and LOD was 0.7 ppm.Unpublished improvements have been made to the PFOA method providing for an LOQ of 0.5 ppm and an LOD of 0.15 ppm. This improved method wasused in 2007 - 2011.As noted above, the values obtained for this reporting were determined by measurements of actual finished products. Where possible three separate lots ofmost every major product were analyzed and then averaged.iiFluoropolymers manufactured with PFOA.iiiUse the following ranges: (1) Zero (2) > 0 – 10 kgs; (3) > 10 kgs – 100 kgs; (4) > 100 kgs – 1,000 kgs; (5) > 1,000 kgs –10,000 kgs; (6) > 10,000 kgs –100,000 kgs; (7) > 100,000 kgs – 1,000,000 kgs; (8) Over 1,000,000 kgs.ivConcentration should reflect the concentration of chemical in the product as sold by the reporting company. If the reporting company has informationconcerning the concentration of chemical in the product as used by others – forexample, as incorporatedby dilution into a formulation – that additionalinformation would also be helpful.vThis value should be expressed as a weighted average concentration and range.viThis value should be expressed as a maximum concentration.viiThis value should be expressed as a simple (not weighted) average and range.Public Version June 30, 2015
