Comments on Draft Permit
(Peer Review notes from Sydney Carpenter)
Box
• Make sure to be including the Stream Index number and HUC code on the Supplement to
Cover Sheet. The Stream Index can be found on the Outfall window in BIMS. The HUC can be
found using the 'Find Your HUC' GIS site or the 'DWR Map' GIS site. I've added it to draft
permit for you so you can see where I normally put it. This makes it a huge help in identifying
the exact stream for later renewals or any questions we might get!
• The facility's Grade/Classification was missing under A. (1.). Older permits won't have this, so
it's something to look out for and add when you're doing a renewal. You can find this info on
the 'Class/Desig.' tab in BIMS. WW-2 means it's a Grade II Biological facility. If you ever see a
facility classification as'PC-1', that means it's a Physical/Chemical classified facility (15A NCAC
08G .0306).
• We usually always format the Effluent table using the'Arial Narrow' font to help everything
fit. The rest of the permit stays in Times New Roman.
• One thing I forgot to mention regarding the effluent table is that we've been updating where
it says 'Parameter' to 'eDMR' for the code now that permittees can submit through our eDMR
system.
Factsheet & Cover letter
• See the comments I've added to the documents! All minor corrections.
Map
The receiving stream name and receiving stream index # are missing from the map. I'd update
it to include this information for easy reference

From Jenny Graznak — last inspection was 2019 and was unremarkable. Site is not a repeat
violator.
