Subject: RE: DRAFT permit renewals for 4 Catawba County Schools
Charles
I noticed that 3 out of the 4 permits you sent down have weekly temperature monitoring with Bunker Hill HS being the
lone exreption with Vweek temp monitoring. Don't knew if this is a typo or not, but I would think they all should be the
a'h i think %ve should remove temp monitoring on fa! OId we like this anyway. Given the type of treatment
systems they have and the source of the wastewater treated, collecting temnerature data at a facility like this seems
meaningless and really doesn't provide is with any nsefid data 4ny thermal influence that might be added to the
wastewater coming from the srhool would be quickly dissipated in the sent c tank and would have no real effect on
treatment nor would it be expected to show up in the effluent. I ,guess however, if our permitting guidance says it
