Permit Summary
NCO066991
This is a permit renewal for a discharge' into Beaverdam Creek in the Watauga,
River Basin. Within the past twenty four months this facility had one violation
of BOD5., Downstream temperature values were above 20'C only during
August of 1995. Fecal Coliform seems to be of some concern. The facility
inconsistantly discharged levels above 200/100 ml of fecal colifonn within the
past twenty four months. Downstream levels for fecal coliforrn were also
inconsistantly high within the past twenty four months. Fecal levels were very
high in early 1995. Permits and Engineering will recommend existing limitations
with monitoring reflective of a class II facility. Regional comments must include
the need for this facility to have disinfection and fecal limits. Region must also
verify facility class and components.
