Permits & Engineering Comments:
1. The facility submitted an engineering alternatives analysis (EAA) which included cost of meeting 5
mg/1 BOD5, 2 mg/1 NH3N, and 17 ug/1 chlorine limits. EAA concluded existing WWTP modification
with surface water discharge was most reasonable and cost effective alternative. Facility will
continue to discharge to surface water, therefore limits specified above apply (15A NCAC 02B .0224).
2. The ammonia toxicity mass balance calculation using 7Q10 and permitted flows calculates allowable
concentrations of 1.0 mg/1 (summer)/1.8 mg/1 (winter). However, facility's flow is less than 1 MGD,
thus: a) Division policy requires NH3-N limits no lower than 2.0 mg/1/4.0 mg/1 and b) facility has
choice of 2/4 NH3N limits or chronic toxicity at 90%. Both are specified on proposed effluent sheet,
only one of two conditions will apply. Region please comment
3. Recommend elimination of special conditions D (incorporated into boiler plate) and E (no longer
applicable because more stringent limits incorporated into permit).

This facility has a system sized for only 0.01 MGD. Please revise effluent pages to
reflect this flow. They never applied for an authorization to construct to expand the
plant above the 0.01 MGD. The facility would prefer NH3-N limits. There is no
objection to year round 5/2 limits. This facility plans to tie into a proposed utility in
Avery County which will discharge in Watauga (Chuck Davis is the engineer for the
project.) -_

NCO01U Summary
April 14, 1997
Appalachian State University - Camp Broadstone has applied to renew their permit to
discharge 0.0075 MGD treated wastewater.
The treatment system consists of aeration basin, clarifier, chlorination, and dechlorination.
The treatment system discharges to an unnamed tributary of the Watauga River (Class B-
Trout HQW) in the Watauga River Basin.
Compliance Summary
Review of 1995-96 compliance data indicate the facility appears to be in compliance,
although facility may have trouble meeting new stringent limits. Facility has had a couple
of total residual chlorine violations in March and November 1995.
WLA Summary
The facility discharges into a stream with 7Q10/30Q2=0. Therefore, the facility submitted
an engineering alterantives analysis (EAA) which included cost of meeting 5 mg/1 BOD5, 2
mg/1 NH3N, mg/1 DO, and 17 ug/l chlorine limits. EAA (Ledford Engineering
Incorporated, June 1996) concluded existing WWTP modification with continuation of
surface water discharge was the most reasonable alternative. Areas examined were not
considered feasible subsurface or spray irrigation sites for the following reasons: steep
slopes, rock at depths of 2-3 ft., clayey soils, located in floodplain. In addition, cost
analyses showed WWTP modification alternative to be considerably cheaper than other
alternatives. EAA shows that surface water discharge should continue. WLA (Goodrich
2/92) states that if facility does not remove discharge, new stringent limits will apply.
The ammonia toxicity mass balance calculation using 7Q10 and permitted flows calculates
allowable concentrations of 2.0 mg/1 (summers)/4.0 mg/1 (winter). This facility's permitted
flow is less than 1 MGD and therefore has choice of 2/4 ammonia limits or chronic toxicity
limit at 90%.
The chlorine toxicity mass balance calculation using 7Q10 and permitted flows calculates an
allowable concentration of 17.0 ug/l.
Recommend elimination of special conditions D (incorporated into boiler plate) and E (no
longer applicable because more stringent limits incorporated into permit).
