Wasteload Allocation Summary (approach taken, correspondence with region, EPA, etc.) The Town of Yadkinville has applied for a permit to expand its discharge from 1 MGD to 2.5 MGD into North Deep Creek. A level B modeling analysis conducted for the expanded wasteflow predicts that the dissolved oxygen standard will be protected with summer limits of BOD5=16 mg/L, NH3-N=2 mg/L, and DO=5 mg/L. A reasonable potential analysis for toxicants was conducted based on 1994-1996 DMR effluent data. The most notable changes to the permit that are recommended based on this analysis are as follows: • The lead limit can be reduced to monitoring. The effluent contains relatively low levels of Pb and the Pretreatment Unit does not anticipate that Pb will be a significant component of the expanded (Unifi's) waste stream. • A limit for Arsenic is recommended as opposed to monitoring, which is currently the permit requirement. Although most measurements for arsenic were well below the allowable, three higher than average measurements in the past two years have triggered a predicted maximum arsenic concentration over twice the allowable. Since arsenic is not prone to false high test results like cyanide, more frequent monitoring (i.e. a limit) for this toxicant is recommended. Region please comment. • The aluminum monitoring requirement can be removed from the permit. In addition to the fact that relatively high levels of Al occur naturally in NC streams, the predicted maximum Al concentration in Yadkinville's effluent is below the allowable. The expanded discharge is not expectd to significantly increase the Al loading to the stream. 7116 7-b,in i s cam✓ kLL (a..i d ) w,tz (Zt• G/Se t ; vw lars /vGr3 2 Yadkinville has had two tox. test failures during the period 1993-1996. These results represent a major improvement in effluent quality with respect to toxicants compared to the late '80s and early '90s when the facility experienced numerous toxicity problems. A review of 1994- 1996 instream data revealed no significant DO problems.

The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is 50 % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be performed after thirty days from the effective date of this permit during the months of ?an., 0tl . Effluent sampling for this testing shall be performed at the NPDES permitted linal effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy Creek Road Raleigh, N.C. 27607 Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will revert to quarterly in the months specified above. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival and appropriate environmental controls, shall constitute an invalid test and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute noncompliance with monitoring requirements. 7Q10 3.9 cfs Permitted Flow 2.5 MGD Recommended by: �J IWC SO %iao�02 i�2�:ll/ .

These limits were based on level B modeling predictions. During '89 and '90 the facility experienced numerous toxicity test failures. These toxicity problems were likely the impetus fur the extensive metals monitoring/limits requirements in the '93 permit. Accordin : to the 1993 staff report the facility relocated its discharge from Haw Branch to North De - p Creek in July 1992. D D For the '97 WLA 1994-1996 DMR data was used to run a reasonable potential analysis of toxicants. The results of the analysis are summarized in the fact sheet for WLA request #8550. The only recommendation in question based on this analysis is for arsenic. Most of the arsenic concentrations measured were well below the allowable with the except of three readings. These higher than average measurements which occurred in '95 and '96 triggered predicted maximum arsenic concentration over twice the allowable. According to Tom P o e (Pretreatment), arsenic is not prone to false high test results like cyanide. Since the cause of the high arsenic measurements is not known, expanded monitoring (i.e. a limit) is recommended. The additional data points provided by more frequent monitoring of arsenic may help to further quantify the extent of the problem, if there is one. A review of 1994-1996 instream data did not reveal any significant DO problems in North De t p Creek. WLA in 1997 Yadkinville has applied for an expansion of its NPDES permit from 1 MGD to 2.5 MGD. This expansion is predominantly in response to Unifi's request for an additional flow allocation. Although the EA did not clearly state the wastewater characteristics of the expanded flow, Pretreatment has indicated that the majority of the flow will be comprised of recycled cooling water. As a result the waste stream may contain a high mineral salt content. Therefore, conductivity monitoring has been recommended for the effluent. The level B model framework used in the 1.2, 4, and 5 MGD speculative requests was used for the 2.5 M D model. 16/2/5 limits were recommended based on the model. A winter DO limit of 5 g/L was recommended even though the model indicated that this limit was not necessary Since a 5 mg/L winter DO limit was already in the 1 MGD permit, it seemed reasonabl to leave it in the permit for consistencies sake - no other reason. e instream monitoring locations remained unchanged from the current permit. The NCSR 1146 downstream location is the closest of the two locations to the predicted DO sag for a 2.5 MGD discharge. Yadkinville has indicated that they are interested in participating in the Yadkin Basin Dischargers Association.

Hunt, Jr„ Governor Jonathan B. Howes, Secretary 10 February 1997 MEMORANDUM TO: M xk i1cIntire, Environmental Engineer NPDES Group FROM: AA ciEHNR DIVISION OF WATER QUALITY Corey Basinger, Environmental Engineer WSRO - Water Quality THROUGH: Steve Mauney, Supervisor WSRO - Water Quality SUBJECT: NPDES Permit Modification Permit No. NC0020338 Yadkinville WWTP Yadkin County I have reviewed the submitted application and request for flow expansion from 1.0 MGD to 2.5 MGD at the subject facility. Although no paperwork, plans, or specifications were received by the Winston-Salem Regional Office, I had the opportunity to review the preliminary plans and specifications at the Mayor's office and found no reason to deny this request. Regional Office staff met with representatives from the Town of Yadkinville to discuss the expansion. As per those discussions, it is evident that the Town is ahead of their proposed schedule. (Attached is a copy of the most recent staff report) WSRO recommends the requested flow expansion be granted in accordance with current Division guidelines. cc: WSRO 585 Waughtown Street, Winston-Salem, North Carolina 27107-2241 Voice 910-771-4600 N*C FAX 910-771-4631 An Equal Opportunity/Affirmative Action Employer 50% recycled/10% post -consumer paper Reduce Reuse Recycle c Page 1 Message for Andy McDaniel From: Ruth Swanek Date: Tue; Jan 21, 1997 1:53 PM Subject: RE : Yadkinville's Permit To: Mark McIntire Andy McDaniel; Carla Sanderson Cc: Mark - Usually we don't look at individual metals limits in spec requests so we may need to look at that issue again. Andy- Please pull Yadkinville WLA file and see if we would need to review any of this information again. If not, send a mail message to Mark indicating that the limits in spec letter (include date) are adequate and no formal WLA is needed (run that by region too - they may not have reviewed spec letter in detail). Put a copy of any such correspondence into WLA file for future reference. If we need to do WLA (or region wants one), please make it a priority. If you haveiother work that is also a priority, please let me know and we will figure out a schedule for you. Thanks.
