Canpostn Composition: Iv mt crt 81a 0pra trth le 15act The material is approximately 85 to 95 percent water with the other 5 to 15 percent a ac teps ttl ly CB 7,04. C3 fluorochemical acids or salts. ean: av vy SorF14o3 ti The fluorochemical portion of this material is fully fluorinated C8, C7, C6, C5, C4, C3 BS o tn 10s Ch camer adds/salts. These are not Sulfonated, and are very similar to FC-143 (F-6514) or E mriolchp amit ote e FC-118 (F-8178). Based on lab data collected from 10 samples the C8 content of the ET Es sans Yolo O01 F-6002 material ranges from about 0.0015 pounds of C8 per pound of F-6002 up to oeoC tows tiny apps (7CECH) 0.028 pounds of C8 per pound of F-6002 (an average of the ten samples yields 0.01 Ee ss oSsoos po 4502 pounds per pound of F-6002). Total lower boiling compounds (C7+C6+C5+C4+C3) range from .01 pounds per pound of F-6002 up to 0.12 pounds per pound of F-6002. source SOUI'Ge: Iv 032 at pric ss aby riod uofmtho 8y3cdcrmaotvoen The0-34 The F-6002 matedal is produced as a by-product of the C8 acid fractionation in BC-34 in a evi po ar iol ol Building 15. The acid fluodde is stabilized using sodium hydroxide and water. The id hope ot 35 oo fo stabilized acid is then phase spitted from the water phase. A small portion of this water phase remains in the stabilized acid and is stdpped out as a by-product of the acid Pn fractionation. pa tons Disposal options: + Sancroouz eves. 1.

Re-process the matedal here at Cottage Grove. Due to the low concentration of the C8 portion of the matedal it may be more cost effective to ship the matedal to fae Decatur. 4 Sot F021 he rts THsck vrexpr. 4. Send the F-6002 to the incinerator.
