Evidently, Preston Howard wrote letter (12/12/96) to facility requesting resolution of several of these issues. Model Results Using estimated flows of s7Q10=1.2 cfs, w7Q10=1.8 cfs and QA = 7 cfs Level B modeling analysis: For summer, effluent limits of BOD5=30 mg/l, N113=13 mg/l (for toxicity) predicts DO min. of 7.19 mg/1, 0.6 mi. downstream of outfall. End DO = 7.29 at milept. 1.6 mi. For winter, effluent limits of 30/30 protects w/ DO min. of 9.30 mg/l at outfall. If assume that s7Q10 = 0.05 cfs, because of irrigation, not quite drying up the stream completely but with minimal flow enough to consider it with positive flow. 1) @ BOD5=5, NH3=2, DO = 6, DO min. = 6.67 mg/1 @ outfall. 2) @ BOD5=17.5, NH3=6.5, DO =6, DO min. = 6.11 mg/l, 0.5 mi below outfall. 3) @ BOD5=13.5, NH3=7.5, DO =6, DO min. = 6.11 mg/1, 0.5 mi below outfall. 4) @ BOD5=27.5, NH3, DO =6, DO min. = 6.13 mg/l, 0.5 mi below outfall. ***In order to protect Lewis Creek from any potential DO problems because of the irrigation practice, will recommend that tertiary limits be given because of the assumption of 7Q10=0 (or very close to 0 ) and 30Q2>0. The other limits recommended by modeling predict the DO min. so close to 6 mg/l that I do not think that these limits will give the best protection for Lewis Creek. 4/29/97 Dave Goodrich says that Western NC Justice will be changing the discharge location from Lewis Creek to Clear Creek. Preston Howard has promised a quick turnaround on the new location. Map was submitted and the new site was Clear Creek at Gilliam Road. There is still some discrepancy about the amount of wasteflow, does not appear that 50,000 GPD of flow can be justified. P&E came up with Only 10,000 GPD needed, but Preston has said that he will allow an additional 11,000 GPD for any future connections to this plant. Wants to be considered as a regional facility. Ran two models at the Clear Creek discharge point. 1) Qw=0.025 MGD, P&E can justify 10,000 GPD and Director will allow an additional 11,000 GPD for future tie-ons that Academy has indicated will occur, will round up this 22,000 GPD to 25,000 GPD. 2) Previously requested Qw of 0.050 MGD. Level B model results indicate that secondary treatment of 30130 limits will protect DO in Clear Creek. Also recommend fecal limit of 200/100ml and TRC limit of 28 µg/I.

Environmental Enginee SUBJECT: Western North Carolina Justice Academy Pending application -n Henderson County As we are waiting on resubmittal of the application for the WNC Justice Academy discharge permit, some additional information has come up that coulT affect the issuance of the permit. I was informed by a farmer in the area that Lewis Creek, the proposed receiving stream, is used extensively for,p irrigation, to the extent that it is "dried up" at the point of the proposer` discharge during dry periods. This may need to be considered in running the waste load allocation. I will try to find out more information to include in the staff report when it is requested. If you have any questions, please give me a call.

Last week, I talked to Linda Wiggs, a technician, in the ARO, who told me that there was some public concern about this facility. She had attended a public meeting where the proposed discharger was discussed quite a bit. They would prefer the facility connect to the Hendersonville plant. She also mentioned that farmers used this stream, Lewis Creek, for irrigation but at that time, no one indicated that the stream would be dry. They did not have an idea of how much water was withdrawn for irrigation. While talking with Linda, I determined that I would probably have to estimate the flow using USGS equations. If my calculations indicate that there is positive flow, and these citizens want to say that at 7Q10, this stream has zero flow, they may have to do some stream measurements to prove their case. I did tell Linda that public concern and outcry, is one alternative that will be considered, if they are seriously opposed to the Justice Academy discharging. I will be looking for a copy of the letter and will discuss with Carla and Ruth on how we can handle this. From: Steve Pellei on Wed, Mar 12, 1997 1:54 PM Subject: WNC Justice Academy (NC0086070) To: Jackie Nowell FYI.... Received a call from a concerned group of local community members saying that the stream to which the WNC Justice Academy (NC0086070) is proposing to discharge to often has no flow in it due to irrigation. I requested that they send in a letter stating this and provide us with additional information. I have not received anything yet but will pass it onto you when I do. Just a heads up.
