SUBJECT: Re-evaluation of Granite Falls Effluent Limits
The allocation for the Granite Falls WWTP has been
redone. The lake model originally used to determine the
allocation has been updated and revised. It now includes
the effects of dispersion. Using this Level Blake analysis,
the following limits would apply to the Granite Falls WWTP
at its present location:
Qw =
0.75 MGD
BOD5
= 30 mg/l
NH3 =
12 mg/l
DO =
5 mg / 1
TSS =
30 mg/l
pH =
6-9 S.U.
Fecal
Coliform = 1000/100 mi.
