Raleigh Central Office has not yet received renewal application. Mike Mickey indicated to Paul Clark (April 15, 1997) that facility intends to renew permit. 2. The facility submitted an engineering alternatives analysis (EAA) which included cost of meeting 5 mg/1 BOD5 and 2 mg/1 NH3N (both summer) limits. EAA concluded WWTP modification with surface water discharge was the most reasonable and cost effective alternative. Facility has had to comply with 5/2 limits (15A NCAC 02B .0224) since 11/1/95. 3. The Division may want to require facilities that discharge to B-trout HQW waters to meet 5/2 limits all year if they are capable (see The Ponds). Region please comment. 4. The ammonia toxicity mass balance calculation using 7Q10 and permitted flows calculates allowable concentrations of 1.0 mg/I (summer)/1.8 mg/I (winter). However, facility's flow is less than 1 MGD, thus: a) Division policy requires NH3-N limits no lower than 2/4 mg/1 and b) facility has choice of 2/4 NI-I3N limits or chronic toxicity at 90%. The 2/4 ammonia limits are already in their permit. Region -please confirm that facility prefers ammonia limit to chronic toxicity. . . 5. Facility discharges into trout waters, recommend adding footnote prohibiting instream temperature from increasing more than 0.5° C as a result of the discharge (15A NCAC 02B .0211 and .0219). 6. Recommend elimination of special conditions D (incorporated into boiler plate) and E (no longer applicable because more stringent limits incorporated into permit).

FAX 910-771-4631 An Equal Opportunity/Affirmative Action Employer 50% recycled/10% post -consumer paper NC0049174 Summary April 15, 1997 Smoketree Lodge Condominiums has applied to renew their permit to discharge 0.0210 MGD treated wastewater. Treatment system consists of bar screen, aeration basin, clarifier, chlorination and dechlorination and discharges to an unnamed tributary of the Watauga River (Class B-Trout HQW) in the Watauga River Basin. Compliance Summary Review of 1995-present DMRs indicate the facility has had regular violations including: 56.0 ug/1 (chlorine-9501), 474/100 ml (fecal coliform-9506), 0.028 MGD (flow-9605), 9.5 mg/1(BOD5-9605), and 8.5 mg/1 (NH3-N, 9611) and violations also occurred prior to 1995. None of the violations appear to be parameter specific. In June 1995, fecal coliform increased dramatically downstream of discharge likely as a result of high effluent value. WLA Summary The facility discharges into a stream with 7Q10/30Q2=0. During the most recent permit period, the facility submitted an engineering alternatives analysis (EAA-940414) which included cost of WWTP modification to meet 5 mg/1 BOD5 and 2 mg/1 NH3N summer limits. EAA concluded WWTP modification with surface water discharge was the most reasonable and cost effective alternative. Facility has had to comply with 5/2 limits (as required by 15A NCAC 02B .0224) since November 1, 1995. 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 2/4 mg/1 and b) facility has choice of 2/4 NH3N limits or chronic toxicity at 90%. The 2/4 ammonia limits are already in their permit. Region should confirm that facility prefers ammonia limit to chronic toxicity. The chlorine toxicity mass balance calculation using 7Q10 and permitted flows calculates an allowable concentration of 17.0 ug/l. Instream Monitoring Facility discharges into trout waters, recommend adding footnote prohibiting ambient stream temperature from increasing more than 0.5° C as a result of the discharge (15A NCAC 02B .0211 and .0219). Review of instream monitoring data for the period 1995-present indicate that the discharge does not appear to be adversely impacting the receiving stream. Temperature, dissolved oxygen, fecal coliform, and conductivity values were very close if not identical at the up - and downstream stations the majority of the time. The exception was one high fecal coliform value at the downstream station in June 1995. Other Items Recommend the following: a) changing BOD5 and NH3N sample type from grab to composite, b) changing frequencies of several parameters and adding total nitrogen and total phosphorus monitoring on a semi-annual basis to be consistent with 02B .0500, c) changing Total Suspended Residue monthly average from 30.0 mg/1 to 10.0 mg/1 to be consistent with water quality standard for trout receiving waters, and d) elimination of special conditions D (no longer applicable because 5/2 limits incorporated into permit) and E (incorporated into boiler plate).
