Water Quality-Based Effluent Limitations (WQBELs) Oxygen-Consuming Waste Limitations Limitations for oxygen-consuming waste (e.g., BOD) are generally based on water quality modeling to ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits (e.g., BOD= 30 mg/l for Municipals) may be appropriate if deemed more stringent based on dilution and model results. If permit limits are more stringent than TBELs, describe how limits were developed: See discussion below. Ammonia and Total Residual Chlorine Limitations Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of 1.0 mg/l (summer) and 1.8 mg/l (winter). Acute ammonia limits are derived from chronic criteria, utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non-Municipals. Although a Streeter Phelps model (Level B) indicated that Line Creek has capacity for CBOD, the water body does not have capacity for NBOD. CBOD capacity is greater because of the greater slop along the stream reaches. With a 7Q10s of 0.13 cfs the instream waste concentration for Line Creek is 35%. There is not sufficient dilution for toxicants such as ammonia. The allowable concentration for ammonia toxicity is 2.5 mg/l for summer and 5.7 for winter (See attachment B1, also B2 for NC0075680 Rose MHP). High Vista Falls WWTP currently has a year-round Ammonia limit of 1.0 mg/l (4.57 mg/L NBOD), which is the optimum value that met the instream NBOD standards for the model. Therefore, ammonia limitation is based on the Level B model assessment of NBOD capacity rather than the allowable concentration for ammonia toxicity. Please see the attached Level B model graphs for summer and winter below.

Cc:adugna.kebede@ncdenr.gov; Montebello, Michael J; Dowden, Doug; Litzenberger, Kristin S; Denard, Derek; Albertin, Klaus P; Weaver, John C Subject:USGS response to DWR USGS Low Flows request # 2023-268 (dated 2023/05/10) for Line Creek Buncombe Henderson Counties...RE: [EXTERNAL] Low-flow request approval   Derek,    In response to your inquiry about the low‐flow characteristics for a location on an unnamed tributary to Line Creek  downstream from NC Highways 191/280 near Buck Shoals along the boundary between Buncombe and Henderson  Counties, the following information is provided:    A check of the low‐flow files here at the USGS South Atlantic Water Science Center (SAWSC, Raleigh office) does not  indicate a previous low‐flow determination for the specific point of interest, identified by the lat/long coordinates  (35.43128, ‐82.57225) provided via email dated 05/10/2023 from the DWR USGS Low Flows portal following your  request submission.  However, low‐flow estimates have previously been estimated for two nearby locations (one each  upstream and downstream from the point of interest) on Line Creek.  Completed in December 1988, the low‐flow  characteristics were estimated based on transfer of flow characteristics from a USGS partial‐record site on nearby Avery  Creek near Fletcher (station id 03447766, NWIS drainage area = 8.59 sqmi).    No USGS discharge records are known to exist for the point of interest.    In the absence of site‐specific discharge records sufficient for a low‐flow analysis, estimates of low‐flow characteristics at  ungaged locations are determined by assessing a range in the low‐flow yields (expressed as flow per square mile  drainage area, or cfsm) at nearby sites where estimates have been determined.    A basin delineation completed using the online USGS StreamStats application for North Carolina  (https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats adjusted  coordinates 35.43140, ‐82.57226 NAD83) is 0.35 sqmi, which confirms the drainage area submitted as part of the  request information.    For streams in Buncombe and Henderson County, low‐flow characteristics published by the USGS are provided in the  following reports:    (1) The first is a statewide report completed in the early 1990's.  It is USGS Water‐Supply Paper 2403, "Low‐flow  characteristics of streams in North Carolina" (Giese and Mason, 1993).  An online version of the report is available at  http://pubs.usgs.gov/wsp/2403/report.pdf.  The report provides the low‐flow characteristics (based on data through  1988) via regional relations and at‐site values for sites with drainage basins between 1 and 400 sqmi and not considered  or known to be affected by regulation and/or diversions.    (2) The second is a statewide report published in March 2015.  It is USGS Scientific Investigations Report 2015‐5001,  "Low‐flow characteristics and flow‐duration statistics for selected USGS continuous‐record streamgaging stations in  North Carolina through 2012" (Weaver, 2015).  The report is available online at  http://pubs.usgs.gov/sir/2015/5001/.  The report provides updated low‐flow characteristics and flow‐duration statistics  2 for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic  years discharge records were available for flow analyses.    Low‐flow characteristics estimated for point of interest:    Inspection of the reports indicates the presence of eight (8) nearby selected USGS partial‐record sites (4) and  continuous‐record streamgages (4) from southern Buncombe County into northern Henderson County where low‐flow  characteristics have previously been published.  Of note, this group of index sites includes the USGS partial‐record site  on Avery Creek near Fletcher (station id 03447766, NWIS drainage area = 8.59 sqmi) used for the 1988 low‐flow  estimates at the nearby locations on Line Creek.  Among these 8 index sites, the low‐flow discharge yields for the  indicated flow statistics are as follows:    Annual 7Q10 low‐flow yields ==> from 0.17 to 0.6 cfsm (average about 0.37 cfsm, median about 0.41 cfsm)  Annual 30Q2 low‐flow yields ==> from 0.39 to 1.2 cfsm (average about 0.77 cfsm, median about 0.84 cfsm)  Winter 7Q10 low‐flow yields ==> from 0.25 to 0.74 cfsm (average about 0.49 cfsm, median about 0.52 cfsm)  Annual 7Q2 low‐flow yields ==> from 0.31 to 1 cfsm (average about 0.66 cfsm, median about 0.71 cfsm)    Average annual discharge yields ==> from 1.2 to 3.1 cfsm (average about 2 cfsm, median about 2.1 cfsm)    Application of the above range in yields to the drainage area (0.35 sqmi) for the point of interest results in the following  estimated low‐flow discharges:    Annual 7Q10 low‐flow discharges ==> from 0.06 to 0.21 cfs (average about 0.13 cfs, median about 0.14 cfs)  Annual 30Q2 low‐flow discharges ==> from 0.14 to 0.42 cfs (average about 0.27 cfs, median about 0.29 cfs)  Winter 7Q10 low‐flow discharges ==> from 0.088 to 0.26 cfs (average about 0.17 cfs, median about 0.18 cfs)  Annual 7Q2 low‐flow discharges ==> from 0.11 to 0.35 cfs (average about 0.23 cfs, median about 0.25 cfs)    Average annual discharge discharges ==> from 0.42 to 1.1 cfs (average about 0.7 cfs, median about 0.74 cfs)    Please note:    (1) The estimated flows are provided in units of cubic feet per second (cfs).    (2) The low‐flow yields provided above are rounded to 2 significant figures.  Estimated low‐flow discharges less than 1  cfs are rounded to 2 significant figures.  If between 1 and 100 cfs, then rounded to 1 decimal place; if greater than 100,  then rounded to the nearest whole number (zero decimal places).    (3) The information provided in this message is based on a preliminary assessment and considered provisional, subject  to revision pending collection of future data and further analyses.
