Rex Gleason �ppnn 1'•�"R 2 9 5990 PREPARED BY: Michael L. Parker� SUBJECT: Revised WLA Killian Crossroads WWTP NPDES Permit No. NC 0063355' Catawba County, North Carolina In February, 1989, Mid South Water Systems, a private utility company, acquired ownership of the subject wastewater treatment facility (formerly Don Innes Laundromat). Mid South, however, intended to abandon the existing facility and construct a new facility discharging at the present location. The effluent limitations promulgated for this expansion reflect BOD and NH3 as N (summer) limits of 22 mg/1 and 13 mg/l, respectivaly. As of this date, this Office has no record of plans and specifications being submitted for this proposed expansion. Although positive 7Q10 and 30Q2 stream flow exist at the present discharge location, this Office has concerns that nuisance conditions have been created as a result of the discharge. This Office has documented several complaints from downstream residents who complain of various degratory effects on the lake below this discharge. The proximity of the discharge to local residents and the common practice of lowering water levels during dry periods may further enhance nuisance problems as plant hydraulic capacity increases. The high degree of body contact with the receiving waters (swimming, skiing, wading, etc.) immediately downstream further supports our concerns. Although USGS reflects a "positive" stream flow, the narrow, meandering physical characteristics of the cove receiving the discharge would tend to permit marginal mixing and assimilation of waste constituents. Trevor Clements Page Two March 21, 1990 In addition, due to the suspected marginal mixing of the effluent, this Office has concerns regarding instream ammonia toxicity. If the existing ammonia limitation is not capable of protection against ammonia toxicity then revised limits (as detailed in your memo dated February 5, 1990) should be developed. Nevertheless, this Office recommends that this facility's effluent limitations be revised at least to current BPJ limits BOD5 - 15 mg/l, NH as N - 4 mg/l as is appropriate for all other new or expanding dischargers to Lake Norman. If the new Waste Load Allocation model predicts ammonia toxicity, then the appropriate ammonia limitation should be revised accordingly. If you have any questions, please advise. cc: Dale Overcash MLP:se / 2 7�4 �f E, 02 Q E - _ - - -- - - -- ,=�7- d0 -- 0, 75�, 7r�w D. /3- -- ---- - --- -- li Ij Gv Xe 'I 7� V14 U�l =cU�37d rr7, ava/L `o i� s o 6 t, C.
