The area was storing two 55-gallon containers of lead-contaminated hazardous waste at the time of the inspection.

The only significant erosion was leading into the foundation area (with no drainage leading away from it).

ALiowing 104 GW of firm generation to retire by 2030- without timely replacement-could lead to significant outages when weather condi tions do not accommodate wind and solar generation.

Figure 1: How EQS `targets' seem to have been derived for the 24 PFAS in the Version 2: talking to a decision maker In particular, the proposal sets a unique limit for 24 PFAS (in practice: PFAS limits are set at 4.4 ng/L of PFOA-equivalents, on a sum of 24 PFAS) seem to be arbitrarily low with standards based on improper derivation because of: - The absence of a robust methodology (uncertainties leading to a sum-parameter for 24 PFAS) - The compounding of consistency of effects, using a single study and simplification are leading to significant uncertainty We believe PFAS need to be regulated urgently but based on a robust approach.

EXCHANGE WITH THE BRC PROPOSED PFAS REACH RESTRICTION Fluoropolymers Product Group 7 December 2021 The Fluoropolymers Product Group (FPG) The Fluoropolymers Product Group represents Europe's leading fluoropolymer producers and experts.

Critical applications are in public drinking water supply, in food production (farms & factories), guaranteeing safe water in buildings, hotels, (public) swimming pools In addition, pumps are used to run critical utility processes in Power and Pharma industries Difficulty to disinfect drinking water, worst case leading to interruption of water supply & risk for public health Halting disinfection of wastewater, leading to environmental impact for rivers and lakes.

Subject to identifying substitute formulations with equivalent performances, the inclusion of fluoropolymers in the restriction would lead to a requalification for each case of use (ammunition and pyrotechnic components).

This may lead to situations where facilities with strong safety records are forced to employ duplicative, costly, and/or only marginally improved systems just to comply with the regulation.
