Facility currently discharges to stream with 7Q10/30Q2 = 0. The facility wishes to expand from
0.02 mgd to.053 mgd and relocate to Middle where there is positive flow. Based on a field -
calibrated model for Middle Creek befow unset Lake, no new discharges will be permitted to the
Middle Creek basin. Existing discharges must submit an engineering analysis of alternatives to
surface discharge.
Facility has submitted an engineering report showing no alternative to surface water discharge.
Since this facility is existing and has been permitted in the past for the expanded flow, a permit will
be issued for .053 mgd. However, it is recommended that the facility tie-in to a municipality
within 180 days of availability.

Facility currently discharges to stream with 7Q10/30Q2 = 0. Facility has submitted an engineering
report showing no alternative to surface water discharge. The facility wishes to expand from 0.02
mgd to.053 mgd and relocate to Middle Creek where there is positive flow. Based on a field -
calibrated model for Middle Creek below Sunset Lake, it is recommended that no permit for the
expansion and relocation be issued. No new or expanded discharges will be permitted to the
Middle Creek basin. In addition, the endangered dwarf -wedge mussel has been found on Middle
Creek at NC 50.
