Number of sites should be sufficient to allow prelimina assessment of releases associated with different use ind Monitoring should be sufficient to provide baseline dat allow quantification reduction in environmental release time. For industries that are clustered fewer sites sho needed. -3- Data Need LOI Commitment Use Sites Concentration of PFOA in air, surface water, groundwater, soil, biota wastewater, landfill leachate at processing/use facilities Modeling of air, soil, groundwater concentrations Off Site from Use Concentration of PFOA in air, surface water, groundwater, soil, and biota down gradient from use facilities Modeling of air, soil, groundwater concentrations Item 10: Monitoring- Fluoropolymers EPAData Needs; (Draft 9-21-03) Additional data needs beyond LOI Measured concentrations of PFOA in air, surface water, groundwater, wastewater, soil, sludges biota at use facilities EPA Proposal to Address Data Needs Screening level monitoring studies at facilities representative different user industries. Initially 5-10 "Worse case" sites associated with each use industry should be selected for monitoring similar to that do at manufacturing facilities. Monitoring should be designed provide scoping baseline data to inform future site selection needed, and to allow qualification efforts to reduce releases. Number of sites and locations dependant on information abo number and location of user facilities Monitoring data should be collected sufficient for screening level characterization of PFOA concentrations in environme media at the site and released from the site. Screening level study design is site/industry dependant, but may include: 5-1 surface water samples upstream, at the site, and downstream 20 wells with quarterly groundwater sampling, 5-10 air sam monthly wastewater sampling, quarterly sludgesampling if discharges go to POTW, 20-50 soil samples, 20-50 biota samples Measured concentrations in air, surface water, groundwater, wastewater, soil, sludges, biota down gradient from use facilities Surface water, groundwater wastewater, air, soil, biota (plan herbivores, avian terrestrial species) monitoring studies arou use facilities Data to characterize environmental concentration away from site and to identify limit of environmental contamination Wastewater and sludges from POTWs receiving discharge user facilities should be included -4-
