The facility discharges into a stream with 7Q10/30Q2=0 cfs. Removal of the
discharge will be required if a more environmentally sound alternative is
available. An engineering report evaluating alternatives to discharge is due
180 days prior to permit expiration along with the permit renewal
application. As part of the report, the cost of constructing a treatment facility
to meet limits of 5 mg/l BOD5, 2 mg/l NH3, 6 mg/l dissolved oxygen, and
17 ug/l chlorine must also be included if there are no alternatives to a surface
discharge. Upon review of the results of the engineering report, the Division
may reopen and modify this NPDES permit to require removal of the
discharge, modified treatment designs, and/or revised effluent limitations
within a specified time schedule.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
The facility discharges into a stream with 7Q10/30Q2=0 cfs. Removal of the discharge will be
required if a more environmentally sound alternative is available. An engineering report evaluating
alternatives to discharge is due 180 days prior to permit expiration along with the permit renewal
application. As part of the report, the cost of constructing a treatment facility to meet limits of 5
mg/l BODS, 2 mg/1 NH3-N, 6 mg/l DO, and 17 µg/l chlorine must also be included if there are no
alternatives to a surface discharge. Upon review of the results of the engineering report, the
Division may reopen and modify this NPDES permit to require removal of the discharge, modified
treatment designs, and/or revised effluent limitations within a specified time spwafied4
schedule.
Previous WLA had given the old zero flow policy, but was never permitted with the zero flow
policy due to the short term nature of the permit. MSWS had adjudicated several permits to change
the language regarding POTW connection (ref. 7/29/92 letter from DEM).
Staff report indicates the facility is not well maintained and alternatives should be investigated.
Instream data do not indicate D.O. problems (values do not fluctuate much, could be suspect).

all of the non -discharge options available. Please provide
regional perspective for each option evaluated.
Spray Irrigation: May be possible if connection to municipal
sewer system is not feasible in near
future.
Connection to Regional Sewer System: This will likely be
possible at some point and should be given
adequate consideration in an evaluation.
Subsurface: Not possible.
Other disposal options: None known.
5. Other Special Items:

PART IV - EVALUATION AND RECOMMENDATIONS
This system is not being maintained very well. Numerous
items needing attention were pointed out to the Operator on the
field inspection. This office sent an NOV dated March 29, 1993.
It is recommended that an evaluation of connection to the
municipal sewer system (alternative analysis evaluation) be a
condition in the new permit. This was apparently stated in the
last WLA, but for some reason was not included in the Permit.
Flow monitoring in Permit should be changed to Continuous.
Presently it is listed as Instantaneous. Subdivision continues
to expand and most of Collection System is in low lying areas.
Also, this office advised Engineer of permitted Flow concerns in
letter dated December 1, 1987 (copy attached).
With consideration of the above items, this office has no
objection to reissuance of the permit. It may be wise to limit
the life of the permit to three years or less.

Subject: Building Lot Increase
Frye Bridge Estates
Forsyth County
Dear Russell:
Reference is made to your letter and our meeting of
November 30, 1987, concerning an increase of building lots
in the subject subdivision.
Frye Bridge Estates currently is permitted under NPDES
Permit NCO065587 for a discharge of 27,000 GPD. Design
criteria indicated this facility could treat the wastewater
from sixty-six (66) single family dwellings. However, flow
data submitted by you shows a daily average flow per
dwelling of 109 GPD rather than the 120 GPD that is used for
design purposes.
You have requested that you be allowed to connect nine
(9) additional dwellings onto the wastewater treatment
facility. This would increase the total number of
connections from sixty-six (66) to seventy-five (75).
Based on the information submitted this Office has no
objections to an increase of the number of dwellings
connected by Nine (9) to the wastewater treatment facility.
It should be noted that under no circumstance should the
actual wastewater flow exceed the permitted flow of 27,000
gpd. Exceedance of permitted flow is subject to enforcement
action by the Division of Environmental Management.
