U. S. Environmental Protection Agency July 8, 2003 Draft Agenda Monitoring ECA Technical Workgroup Meeting Wednesday, July 9, 2003 1: 00 4: 00 PM Mission Statement: The Monitoring Workgroup will develop ECA proposal( s) for screening level environmental monitoring of PFOA and PFOA precursors as identified by the Plenary Group. The initial focus will be for data needs identified in item 10 of Table I and item 10 of Table II of the EPA Preliminary Framework document, specifically addressing environmental sampling and monitoring in the vicinity of telomer and fluoropolymer manufacturing and use facilities. The interested parties were supportive of using the existing 3M and DuPont analytical protocols and sampling methods as a starting place to discuss developing analytical protocols and sampling methods specifically addressing PFOA data needs as ECA proposals. In addition, the Workgroup will develop considerations for site selection in monitoring studies.

Meeting Objective: Second scoping meeting to: 1. Clarify the scope of environmental sampling and monitoring activities contained within the industry LOIs ( OPPT 2003 0012 0007; OPPT 2003 0012 0012; OPPT 2003 0012 0013) 2. Discuss monitoring activities and objectives identified within the EPA Preliminary Framework to determine topics for ECA development 3. Prepare workgroup presentation to plenary session and select spokesperson. 4. Identify workgroup next steps and assignments.

° Based on WV toxicity levels LOI Monitoring ° Dispersion Processors   No environmental monitoring   Process modeling LOI Monitoring ° Telomers   No environmental monitoring at processing or use sites   Process modeling LOI Monitoring/ EPA Needs   " Health impact" objective of LOI monitoring not the same as EPA's objective of achieving PFOA source and pathway understanding; different objectives call for different approaches   EPA needs monitoring based on analytical limits ° LOI monitoring decisions based on WV screening levels would not achieve PFOA source and pathway understanding   Air modeling is not sufficient. Actual monitoring of vapor, particulate, and water phase needed LOI Monitoring/ EPA Needs ° No environmental monitoring at telomer manufacture, processing or use sites.

  Processing engineering modeling is not sufficient for determining environmental concentrations.

  Monitoring is required ° Environmental matrix samples insufficient at most sites   No biota, sludge, air etc ° Proposed sampling frequency inadequate at some sites ° Proposed Objective:

  Determine how PFOA and PFOA precursors are released into the environment, their fate and transport once released, and routes and levels of human and environmental exposure.

  Monitoring must provide information on releases and routes of exposure in sufficient detail to understand the contributions of PFOA from various possible sources,

and to inform a cumulative assessment of the exposure. Current Knowledge ° Blood analysis suggests widespread exposure ° Existing monitoring data shows measurable levels of PFOA and possible PFOA precursors in water,

soil, sediments, air, municipal sludges, and biota ° Unidentified pathways for PFOA and PFOA precursors must be identified with full transparency Acceptable Approach Must Include ° Screening level monitoring focused on worst case scenarios ° Manufacturing, processing, and use ° Sampling of all environmental media   Surface water, groundwater, wastewater,

sludge, air, particulates, rain, biota Scope ° Sufficient to identify background levels of concentration and exposure ° Sufficient number of sites to ensure that worst case sites and processes have been identified, and to determine associated level of uncertainty.

° Collect enough data to allow extrapolation to other plant sites and areas ° Manufacturing sites   All ° Processor sites   Selected sites ° End user sites   Representative sites from all processes ° Analyze for PFOA and all known or suspected precursors ° Sampling based on analytical detection limits FMG Presentation to Monitoring Technical Workgroup 1 Monitoring 2 Monitoring ° APFO Manufacturing   Under the LOI, the current US manufacturer will conduct water monitoring and air dispersion modeling on an ongoing basis   Under the LOI, the prior US manufacturer is conducting broadbased monitoring on an ongoing basis   Results at these facilities to be reported to the EPA per the LOI.

° Industry group recommendation   The monitoring programs at these sites are comprehensive and sufficient 3 Monitoring ° Fluoropolymer Manufacturing   Other Manufacturing Sites?

° 75% of the existing manufacturing sites in the US that continue to use APFO are covered in the monitoring studies discussed by industry   Biota Sampling?

° Bio concentration factors are low ° Fish testing by 3M indicates no significant levels   Market basket data?

° Very few random detections/ none replicated 4 APME Study Adsorption/ Desorption of PFOA to Soil ° Adsorption/ Desorption study submitted on July 7, 2003 ° Used OECD 106 Guidelines Adsorption/ Desorption of PFOA to Soil ° Representative Results  Adsorption Coefficient, Kd   Silty Clay Loam, 4.25 8.86 mL/ g ( low med foc %)

  Sandy Clay Loam, 0.41 0.83 mL/ g ( low foc %)

  Wilmington Sludge, 12.6 36.8 mL/ g ( high foc %)

° Natural soils all displayed very low Kd values ° Key conclusions   PFOA has low affinity for adsorption onto soils   Low foc soils desorb PFOA better 5 APME Study Adsorption/ Desorption of PFOA to Soil, cont.

° LHWA Soil Investigation consistent with APME Study ° Results:

  Near surface, fine grained, higher foc soils displayed highest PFOA in soil results ( highest was 170 ug/ kg)

  Deeper, coarser soils ( i. e., sands) displayed very low to ND results ° Industry Group Recommendation   Based on actual results in Ohio and adsorption/ desorption testing results, there is no need to do soil testing. 6 Dispersion Processor Material Balance ° Dispersion processors   Water sampling ° Protocols for sample collection and sample analysis are being chosen consistent with WV MMCO   Air sampling ° Protocols for stack sample collection and stack sample analysis are being chosen consistent with WV MMCO   Sampling will be conducted at the following dispersion processor types ° Metal coaters/ formulators ° Glass cloth coaters ° Additives ° Others by processing temperature   Results will be submitted to EPA by the end of 2003 7 Monitoring ° Summary/ Recommendations   APFO Manufacturing Monitoring data to be reported to EPA as defined in the LOI   Fluoropolymer Manufacturing Monitoring is sufficient as planned and/ or completed.
