Dear Sir/Madam:

2010/15 PFOA Stewardship Program Report

DuPont is pleased to submit its annual report describing our progress in meeting the 2010/15 PFOA

Stewardship Program goals. The report describes accomplishments in 2013 against the major

milestones set when the program launched in January 2006.

For 2013, DuPont has reduced its facility emissions and product content by over 99.5% from the base

years established for this program. DuPont made additional progress toward the second program goal

to work toward elimination of PFOA and related chemicals by 2015. Consistent with the DuPont

commitment in 2007 to no longer make, buy or use PFOA by 2015, or earlier if possible, DuPont ceased

its manufacture of PFOA in first quarter 2013. DuPont also eliminated use of PFOA in the manufacture

of fluoropolymers as of the end ofJune 2013 and in perfluoroelastomers as of the end of December

2013, two years ahead of the EPA goal. We made additional progress in our remaining product line, and

by the end of 2013 had converted nearly 90% of the fluorotelomer products to short-chain chemistry

that cannot break down to PFOA in the environment. We are on track to complete this conversion to

alternatives for the remaining fluorotelomer products by the end of 2014.

Since our transition to alternatives will be completed at the end of 2014, DuPont will submit its final

report for the PFOA Stewardship program in 2015. We expect to submit this documentation for this

voluntary program at the end of the second quarter 2015. DuPont continues to support appropriate

science-based regulation and looks forward to completion of the Chemical Action Plan by the US EPA to

address the manufacture and use of long-chain perfluoroalkyl substances (PFAS) by manufacturers,

importers and processors that have not participated in the 2010/15 PFOA Stewardship Program.

The general methods used for the analyses repor ted here have been published in the following

article:

Full year bestestimates based on anticipated product mix and site production splitPFOA Reduction overall is nearly 99%;IDPs reduction overall is 97%Company Sanitized Public Version OCTOBER 31, 2014LOQs for analytical methods for impurities inDuPont FT products is 2 ppm. 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.

Journal of Chromatography A. 2006 (1110), 117-124. 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.
