In thisprocess,organic feedstocksaredispersedin liquid,anhydrous hydrogen fluoride,and an electricurrentispassed through the solution,causing the hydrogen atoms on the molecule to be replaced with fluorine.The predominant components of the products created by thisprocess have the same carbon skeletalarrangement as the feedstockused, but with allof the hydrogen atoms replaced by fluorine.However, fragmentationand rearrangement of the carbon skeletoncan alsooccur and significanatmounts of cleaved,branched and cyclicstructuresmay be formed. The degree of fluorinationof theorganic feedstockisalsodependent upon the specific carbon chain length of the feedstockand parameters of the ECF process such as electricaclur-rentand the lengthof time theprocess isrun. Itispossibleto synthesizefullyfluorinatedor perfluoroorganic molecules where allof thehydrogen atoms of thehydrocarbon feedstockhave been replaced by fluorineatoms. Using theseperfluoroorganicmolecules as basicbuildingblocks,unique chemistries can be createdby furtherreactionswith :ftmctionalizehdydrocarbon molecules. 3M has produced sulfonylbased fluorochemicalsconunerciallyforover 40 years using the ECF process.A basicbuildingblock of such productsand thehighestproduction volume fluorochemical 3M manufactures isperfluorooctanesulfonyflluoride(POSF). The startingfeedstockforthisreaction is I-octanesulfonylfluoride. (Reaction1) Reaction I C8Hl7SO2F + 17 IF I-Octanesulfonylfluoride Energy ------->-- CgFl7SO2F + 17 H2 ECF Perfluorooctanesulfonyflluoride The electrochemicalfluorinatiopnrocess yieldsabout 35%-40% straightchain (normal) POSF, and a mixture of biproductsand waste of unknown and variablecomposition comprised of the following: 1) higherand lowerstraight-chahionmologs,i.e.n,-CnF2n+IS02F,e.g.C,6Fl3SO2F, C7Fl5SO2F, C9Fl9SO2F which compriseabout7% oftheprocessoutput 2) branched-chain,perfluoroalkylsulfonyflluorideswith variouschain lengths,about 18-20% of the output 3) straight-chainb,ranched, and cyclic(non-:ftmctionalp)erfluoroalkanesand ethers,which comprise about 20-25% of theoutput 4) "tars"(highmolecular weight fluorochemicalbyproducts)and otherbyproducts,includingmolecular hydrogen, which comprise about 10-15% of the output. Because of slightdifferencesin processconditions,raw materials,and equipment, themixture produced by the electrochemicalfluorinatiopnrocess variessomewhat from lot-to-loatnd from plantto-plant.The product thatresultsfrom electrochemicalfluorinationisthus not a pure chemical but rathera mix of isomers and homologues. The commercialized POSF derived products are a mixture of approximately 70% linearPOSF derivativesand 30% branched POSF derivedimpurities. CAS Number 1691-99-2 3M Company 3 During production,byproductsand waste productsareformed.

The treatment sludge associated with the ECF process has been either landfilled or land-incorporatedin the past,but allof thistreatmentsludgeisbeing landfilledoff-sitesinceearly 1998. POSF isitselaf commercially viableproduct,but isprimarilyan importantintermediatein the synthesisof substancesused in many other3M fluorochemicalproducts. The majority isused to produce fimctionallyderivatizedfluorochemicalsand high molecular weight polymeric products. Unique chemistriescan be createdby derivatizingPOSF through the sulfonylfluoridemoiety of the molecule usingconventionalhydrocarbon reactions.POSF isreactedwith methyl or ethylamine to produce eitherN-methyl or N-ethylperfluorooctanesulfonamide(MEFOSA or ETFOSA). Some of the MEFOSA and ETFOSA isisolatedto be used as intermediatesto be reactedto form other materials. The majority of theMEFOSA and ETFOSA isnot isolatedand subsequentlyreactedwith ethylene carbonateto form eitherN-methyl or N-ethylperfluorooctanesulfonamido ethanol..These arethe principalbuildingblocks of the3M product lines. CAS Number 1691-99-2 3M Company 4 The followingblockflow diagram describestheprocessdiscussedabove.

For privacy considerations, please do not include any personal identifiers such as a worker's name or social security number with any data submitted to EPA. Personal sampling for these materials is currently (late 1999 to present) done using OSHA VersatileSampler tubeswith XAD-4 resinand mixed celluloseesteror glass fiberprefilter. Sample analysisisby LC-MS. Previous sampling had employed silicagel acidmist tubes with GC-ECD analysis.See attachedtableforairsample results. There has been area/sourceairmonitoring data and/or surfacewipe sampling data collectedfor thismaterialatthe plant.Area/source sample resultsand/orsurfacewipe sample resultsareused to identifyareaswith employee exposure potentialas partof exposure assessment under 3M's industriahlygiene program and arenot measurements of actualemployee exposures. Hence, they arenot included with thissubmission. Priorto 1999, thesesamples were considered to be semivalidated. Surfacesin production and administrationareaswere sampled in 1998. A glassfiberfiltewretted with methyl alcoholwas wiped insidea 10 cm x 10 cm squarewith analysisby LC-MS. Results indicatedthe presence of these materialson floorsand equipment surfacesin production areas. This resultedin improvements to Hazard Communication practicesp,ersonal hygiene emphasis, personalprotectiveequipment emphasis, and severalengineeringand administrativechanges. The sample resultsof any airmonitoring are compared to 3M's voluntaryexposure guideline (EG) of 0.1 mg/m3 (milligramsoffiuorochemicalper cubicmeter of air)forvarious fluorochemicalcompounds, includingcompounds covered in thissubmittal.The EG isan 8-hour time-weighted average (TWA) personalbreathingzone exposure chosen to minimize potentialfor uptake.

Hand protection: All tasksidentifiedas having potentialforhand contactrequireneoprene (Scorpio)or nitriliendustriaglloves. Body protection:Exposure significanttasksuse one ortwo-piecePVC suits.Aprons may be wom forsome low exposure potentialtaskssuch as sampling. Foot protection: Tasks identifieads posing a significanftoot exposure potentialrequire chemical resistanbtoots. Current exposures are expected to be lessthan those measured in the recentpast. Significant sourcesof exposure have been identifieadnd eliminated.In 1998 an extensivearea airsampling of the production areaswas performed. Areas with higherlevelsof airbornematerialswere investigatedfurtherto identifysources.These sources,which includethe flakingequipment, are in the process of being eliminatedor reduced through replacement with betterventilated equipment. In addition,theventilatiosnystem in theprimary productionbuilding(3)isbeing upgraded. The fluorochemicalhazard communication program was improved upon in 1998. This has resultedin improved exposure avoidance behaviors among production employees and betteruse of personal protectiveequipment requirements.
