Andrew, Tom Carper is concerned that the proposed MATS rule, in which EPA finds that it is no longer aceappropriate and necessarya to regulate mercury emissions creates the grounds for a successful legal challenge which would overturn the MATS rule. Can you reassure on this? Also, re. HFCs. Although you point out that this is a State decision as to whether to advance the treaty, that he has intel that EPA is strongly advocating against. Can you give reassurance re this? Bill Cassidy Thank you for reaching out. Senator Carper has been pushing both narratives to a number of Senators despite my assurances to him and our staffaTMs assurances to his staff. I am happy to talk to you but the short answer is he is wrong. On MATS we are moving forward with both the necessary and appropriate AS well as the technology review at the same time to make sure it is legally sound. On Kigali, I have not weighed in with the White House or state department. My staff has participated in staff level discussions involving the cost estimates and the need for enacting legislation to provide epa the authority to regulate HFCs as a greenhouse gas under the CAA. At this point I believe it has been on a technical, informational basis. There has not been a principles meeting to discuss since Iaemve been here. I was told last fall that a meeting would be occurring before a decision by the president is made. So there is not a stealth attack on MATS and EPA and/or you are not lobbying against Kigali treaty. That is correct. As I mentioned to you in our meeting we are even offering advice to Honeywell on how they can get what they need Thanks 2024-EPA-05254 Sierra Club FOIA 2024-EPA-05254 ED_017426_00004346-00001 SC_EVERSPLIT0002688
