Martin, Governor S. Thomas Rhodes, Secretary May 5, 1988 Mr. Jim Greenfield USEPA Region IV 345 Courtland Street Atlanta, GA 30365 Subject: Field Survey Notes on South Fork Crooked Creek near proposed Union County 201 Site Dear Mr. Greenfield: R. Paul Wilms Director Enclosed, per your telephone request, is a copy of our field survey notes for South Fork Crooked Creek. As you will note, the receiving stream for the proposed Union County WWTP is subject to zero flow conditions and pooling. From the site description, I think you will agree that if a discharge is placed into these waters tertiary treatment will be required to prevent nuisance conditions and contamination of the groundwater system. For your information, the facility has been warned that future expansion will not be considered favorably by the Division at the currently proposed discharge location (per Division procedure for 7Q10=0, 30Q2=0 streams). An alternative location (w/ a positive 30Q2) has been identified downstream for the county's consideration. Please let me know if I can be of further assistance in this matter.

Paul Wilms THRU: Trevor Clemen.ts�� Steve Tedder FROM: David Vogt SUBJECT: Speculative WLA for Proposed Union County WWTP Per your request, I have performed a Level-B analysis for a discharge to Crooked Creek immediately below the confluence of the North and South forks (attached). The results again demonstrate the Level-B modeling axiom of increased wasteflow actually improving an allocation. This is because increases in wasteflow provide corresponding increases in streamflow, resulting in more momentum being generated within the stream channel. Velocity is thus increased and the decay versus reaeration rates in the model are shifted more toward increased oxygen replenishment. However, previous field studies show that an increase in wasteflow does not always correlate with increased velocity (e.g., the infamous Crabtree Creek WLA). This is mainly due to the Level-B Model relying on our own empirical equation for estimating velocity as well as the Tsivoglou empirical criteria for estimating'reaeration. As you know, empirical relationships are based on cross -sectional data that have upper and lower boundary conditions. If the stream being modeled falls outside the range of streams used to specify these empirical formulae, then the use of the velocity and reaeration equations is suspect and may produce erroneous results. Because Crooked Creek appears to differ in numerous ways from the typical piedmont stream, I would suggest that we perform some field studies this summer before a commitment is made to the effect that unlimited expansion (say up to 10 MGD) will be allowed if Union County sites their plant at this location. It is probably safe to say that limited expansion will be allowed if the plant is designed for tertiary treatment. I have attached a revised -schematic of the area in question for. reference. If you need additional information before making a decision on this matter, please contact Trevor Clements or myself.

Paul Wilms Director SUBJECT: Meeting Summary Crooked Creek Portion - Union County 201 Facility Plan Project No. C370379-01 This letter serves as a summary of the first portion of the December 18, 1987 meeting in regards to permit limitations for the proposed facility. As stated it is current DEM policy to deny NPDES permits for discharges to streams with 7Q10 and 3002 flows equal to 0 cfs. Such is the case for the discharge location of the subject facility; however, since a permit had.been issued'under a previous policy it will be recognized. Based on the fact that the 30Q2 flow is zero for the entire south fork of Crooked Creek no further expansion be -allowed, i.e. plant size will be limited to 1.3 mgd. Additionally, DEM will require effluent and stream monitoring by the facility in an effort to determine if water quality.problems are resulting from the discharge. The Mooresville Regional Office will also perform random field testing to verify compliance and accuracy of submitted monitoring data. Should water quality problems arise, permit revisions may be necessary. This could come in the form of more stringent limits, a reduction in permitted flow ,levels or other actions.

The limits will apply to any one of the sites that Union County wishes to construct a treatment plant. These limits are: Summer Winter BOD5 (mg/1) 5 10 NH3-N (mg/1) 2 4 DO (mg/1) 6 6 TSS (mg/1) 30 30 Fecal Coliform (#/100 ml) 1000 1000 PH (S.U.) 6-9 6-9 Permitted design flows for each of the sites are as follows: NCO069531: 0.10 MGD NCO069841: 1.30 MGD NCO031186: 0.45 MGD DEM had granted these limits in accordance with existing procedure, that is, if 7Q10=0 and 30Q2>0 then do not model but give limits of 5 mg/l BOD5 and 2.mg 1 NH3-N. Since the time that these limits were approved, DEM attempted to do field sampling but observed no streamflow at any of the three sites. Thus, we were unable to do a time -of -travel study or collect water samples for analyzing background conditions. Subsequently, DEM asked USGS to check their 30Q2 estimates for each of the three sites. After performing a field survey, USGS revised the previously positive 30Q2 to zero 30Q2 for the entire south fork of Crooked Creek. Because of this DEM will not permit any future design flow expansion (assuming current operational procedures). DEM will also require effluent and stream monitoring by the facility in order to ascertain if water quality problems are occurring at or downstream of the facility's discharge. The Mooresville Regional Office of DEM will also perform random field sampling to check for compliance and accuracy of submitted monitoring data. If water quality problems are observed, permit revision may be necessary. I feel that is important for Construction Grants to inform the applicant of the limitations of building a wastewater treatment plant on the South Fork of Crooked Creek. This should be done in writing so that there is no question among any of the parties involved, including EPA, what the position of DEM is in this matter. If I can be of further assistance in this matter, please contact me at 733-5083, ext. 161. cc: Dale Overcash Thurman Horne New Facilities (proposed facilities that are being constructed for the first time) If 7Q10 - 0 and 30Q2 - 0, then deny the permit.

A no -flow condition with intermittent stagnant pools existed from SR 1515, (proposed discharge site), to SR 1504, 5.3 mi les downstream. The creek appeared to have been dry for a long time as weeds had grown in the creekbed between the pools. This condition existed even though standing water in area ditches and driveway puddles indicated a recent rain had occured. Stagnant water was observed in the Creek at SR 1004, 7.75 miles below the proposed discharge location. A heavy scum and algal growth covered the surface of the water at this station. Several poultry operation were located just upstream from the the station and may have contributed to the scum and algal problem. Many poultry and agricultural operations are located throughout the survey reach.

DIVISION OF ENVIRONMENTAL MANAGEMENT June 21, 1987 MEMORANDUM TO: Jay Sauber THROUGH: Steve Tedder Trevor C em-�!nts FROM: David Vogt SUBJECT: Preliminary Study Flan for the Proposed Union Co. WWTP to be Located on the South Fork of Crooked Creek: Per your request, I am providing you with suggestions of how to meet the modeling needs for assessing the impact of the proposed Union Co. WWTP #2 on the South Fork of Crooked Creek. After a reconnaissance is done of the area, the plan can be modified to correspond with field observations. Here are my suggestions: - Survey from SR 1008 nr Indian Trail (map G-lb-SW) to SR 1004 nr Denton Crossroads Cemetery (map G-16-SE). - Run time -of -travel analyses from SR 1515 to Ski 1004. - Take flows at SR 1515, 2nd ut, SR 1501, SR 1508, and SR 1004. - Sample for chlorides at flow sites. - I have marked on the maps the existing dischargers to the stream. We may wish to take effluent samples above SR 1515 at a later date if CBOD and/or NBOD are determined to be above background levels. During reconnissance: - Check ut coming in from the north at Route-74; this ut has an industrial discharger (Glenwove, Inc.) located upstream. also check the ut located 0.2 miles west of SR 1513 (this ut provides additional flow for the South. Fork of Crooked Creek. - Examine the effect that a series of small ponds are having on the hydrology of the stream. These ponds are located just upstream of Route 74. - Sample for an instream long-term BOD just upstream of SR 1515. - Temperature, DO, pH, and conductivity should be sampled at SR 1108, both sides of ponds, Route 74, SR 1515, mouth of 2nd ut, SR 1501, SR 1514, SR 1367, SR 15O8, SR 1504, and SR 1004. ].
