Subject: Polyone Resin Mass Calculation - Henry Plant

Jodi, On behalf of Polyone’s Henry, IL facility, we have attached is an example calculation showing how the mass of specific compounds found in the resin and slurry streams was calculated. This example calculation is specific to PolyOne’s Henry, IL plant. This information is intended to be an addendum to the submittal the Henry facility provided to EPA last Friday. Please feel free to contact me should you have any questions. Thanks, Wes Wesley Fritz Weston Solutions, Inc.

Notes:

• Some dried resins had trace levels of moisture, reported as “<1%”. These samples were treated as having 0% moisture (no correction).

• There were 5 grades of resin, G

‐ 1 through G

‐ 5. Grades G

‐ 1 through G

‐ 3 were dispersion resins, and Grades G

‐ 4 & G

‐ 5 were suspension resins. The disp ersion and suspension grades were sampled independently (for both slurry and dried resin).

Analytical results were reported in parts per billion by mass (ug/kg) in resin and slurry for all compounds except acetaldehyde, formaldehyde, and methanol. For those three compounds, lab results were in parts per million (mg/kg). Lab results for acetaldehyde, formaldehyde, and methanol were converted to ppb for calculations (multiplied by 1,000).Example Calculations: Done using Vinyl Chloride and data from 12/9/2009.

Production Data:

Resin Grade Slurry Production

(lbs wet) Slurry Moisture (%) Resin Production

(lbs wet) Resin Moisture (%) G

‐ 1 116,768 62 72,250 1.1 G

‐ 2 119,650 62 97,500 1.1 G

‐ 4 28,350 78 55,519 <1 G

‐ 5 49,200 78 26,000 <1

G1 + G2 = Dispersion Slurry & Resin
G4 + G5 = Suspension Slurry & Resin
Dispersion Grades:

• Total Dispersion Slurry, Dry = [116,768 + 119,650] lb s wet * (1 – 0.62) = 89,839 lbs slurry (dry)

• Total Dispersion Resin, Dry = [72,250 + 97,500] lbs wet * (1 – 0.011) = 167,883 lbs resin (dry)

• Vinyl Chloride, Dispersion Slurry (lbs) = 89,839 lbs dry * 94,000 ppb * 1 x 10 ‐ 9 = 8.44 lbs

• Vinyl Chloride, Dispersion Resin (lbs) = 167,883 lbs dry * 2,500 ppb * 1 x 10 ‐ 9 = 0.420 lbs
Suspension Grades:

• Total Suspension Slurry, Dry = [28,350 + 49,200] lb s wet * (1 – 0.78) = 17,061 lbs slurry (dry)

• Total Suspension Resin, Dry = [55,519 + 26,000] lbs wet * (1 – 0.0) = 81,519 lbs resin (dry)

• Vinyl Chloride, Suspension Slurry (l bs) = 17,061 lbs dry * 2,300 ppb * 1 x 10 ‐ 9 = 0.0392 lbs

• Vinyl Chloride, Suspension Resin (lbs) = 81,519 lbs dry * 630 ppb * 1 x 10 ‐ 9 = 0.0514 lbs
