Note to the rMUR file  -  contacts during comment period
April 6, 2023

On 3/22/2023, Steve Via of ASDWA called Tracy Bone (EPA/OST/EAD) and asked why a PFAS method was not included in the rMUR 2023.  I told him that only non-controversial methods added to routine Method Update Rules (MUR). A PFAS method would be a new contaminant, and therefore would be in a future Full MUR.  Nothing discussed was any different than what is found in the NPRM preamble. 

Adrian Hanley (EPA/OST) on 3/29/2023 described CWA method activities to the Environmental Sciences Section of the American Council of Independent Laboratories annual meeting.  Mentioned the NPRM for the MUR published on 2/21/2023 and comments due 4/24. Noted that there are 37 SM, 2 ATPs, 4 EPA methods, 9 ASTM methods 5 new SMs.  These method updates are non-controversial because all new methods are extremely similar to other approved methods.  Minor tweaks to EPA method. Nothing different than what is discussed in the NPRM preamble.  No questions were asked.
