Re : TSCA 8(e) Substantial Risk Notice : Supplemental to Docket No . 8EHQ-0598373; Sulfonate-based and Carboxylic-based Fluorochemical s
To whom it may concern:
3M is submitting this notice to supplement its previous submissions on sulfonate-based and carboxylic-based fluorochemicals . The enclosed analytical repo rts are pa rt of 3M's ongoing Decatur, Alabama site monitoring program . Interim Repo rt #22 - Analysis of Soil Samples and Interim Repo rt #24 - Analysis of Water, Sludge, and Sediment Samples were prepared by Exygen Research Laborato ry and include data on Perfluorobutanesulfonate ( PFBS), Perfluorohexanesulfonate (PFHS), and Perfl uorooctanesulfonate (PFOS) in subsu rface soil, ground water, su rface water, and sediment collected from sites adjacent to the 3M Decatur production facility . 3M is submitting this report under TSCA section 8(e) .
The specific offsite data that 3M believes are repo rtable are detailed in the enclosed summa ry table. The complete repo rts, which contain both onsite and offsite data, are also enclosed. Please note that although the reports are entitled "Interim", they are audited final reports . The "interim" designation has been applied because the entire Decatur site monitoring work-plan is ongoing .
If you have any questions, please do not hesitate to contact Deanna Luebker at (651) 737-1374 .
