Easley, Governor William G. Ross, Jr., Secretary Gregory J. Thorpe, Ph.D., Acting Director May 21, 2002 Mr. Victor R. Quick City of Graham P.O. Drawer 357 Graham, North Carolina 27253 • • v NCDENR Subject: Issuance of NPDES Permit NC0021211 Graham WWTP Alamance County Dear Mr. Quick: Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended.) The final permit authorizes The City of Graham to discharge up to 3.5 MGD of treated wastewater from the Graham WWTP to the Haw River, a class C-NSW water in the Cape Fear River Basin. The permit includes discharge limitations for flow, biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia, dissolved oxygen, fecal coliform bacteria, pH, total phosphorus, and chronic toxicity. The following modifications have been made to the final permit: • The Division may re -open this permit to require weekly average limits for ammonia. After calculating allowable concentrations, the Division will perform an analysis of past ammonia data to determine if there is a reasonable potential for this discharge to exceed these potential limits. If there is, this permit will be re -opened. If there is not, the permit will not be re -opened, but will contain weekly average limits for ammonia upon renewal • The effluent limitation for cyanide of 22 µg/1 has been deleted from the final permit based on evaluation of the laboratory data submitted by the City. After review of the laboratory sheets, it was determined that the elevated cyanide value reported on March 16, 1999 was probably in error. Since the subsequent cyanide data from the Graham WWTP has been below detection level, the Division has not included a cyanide limit or monitoring in this permit. • The phrase "intermediate clarifiers" was deleted from the facility description per the Town's recommendation. • Mercury continues to be a water quality concern throughout North Carolina. NPDES permittees have worked with the state to reduce potential risks from this pollutant, including tasks associated with collecting and reporting more accurate data. The most commonly used laboratory analysis (EPA Method 245.1) has a detection limit of 0.2 µg/L while the current water quality standard is an order of magnitude lower at 0.012 µg/L. A more recently approved analytical test (EPA Method 1631) should produce a detection limit below the level of the standard. This will allow the Division to assess potential water quality impacts from discharges more accurately. Therefore, beginning on or before September 1, 2003, you will be required to begin using EPA Method 1631 when analyzing for mercury. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone 919-733-5083/FAX 919-733-0719 An Equal Opportunity Affirmative Action Employer 50% recycled / 10% post -consumer paper Issuance of Permit NC0021211 Page Please note the modifications that were in the draft permit sent to you on April 4th. • Instream fecal conform monitoring has been deleted based on revised Division procedure. Graham is a participant in the Upper Cape Fear River Basin Association and is a part of the environmental monitoring plan. Individual instream monitoring has been waived from the NPDES permit. In the event that Graham should leave the Association, instream monitoring for dissolved oxygen, conductivity and temperature will be reinstated. • Per North Carolina regulation 15A NCAC 2B .0506(b)(3)0), the results of all tests on the characteristics of the effluent, including but not limited to NPDES Permit Monitoring Requirements, shall be reported on monthly report forms. All future effluent metals data submitted for Graham's Pretreatment Long Term Monitoring Plan should be reported on the Discharge Monitoring Reports (DEM Form MR-1). Please note that this facility discharges to nutrient sensitive water (NSW) and has an existing total phosphorus limit. In 1997 the Clean Water Responsibility Act (House Bill 515) was enacted, with the intent to strengthen the control of nutrients from all discharges to NSW waters. Facilities currently permitted to discharge > 500,000 gallons per day (and any new or expanding facilities) will be subject to nutrient limitations for total nitrogen and total phosphorus according to House Bill 515 requirements. The nutrient limitations are effective January 1, 2003, unless a compliance extension was received and approved by the Division. The City of Graham was granted a compliance extension and is currently working jointly on a nutrient response model with eight other facilities. Due to the approval of an extension, the nutrient limits will be deferred until results of the nutrient response modeling effort are completed. Please note that modeling results may result in nutrient limits lower than those mandated by House Bill 515. If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be final and binding. Please take notice that this permit is not transferable. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources, Coastal Area Management Act, or any other Federal or Local governmental permits may be required. If you have any questions or need additional information, please contact Ms. Jacquelyn Nowell at telephone number (919) 733-5083, extension 512.

After calculating allowable concentrations, the Division will perform an analysis of past ammonia data to determine if there is a reasonable potential for this discharge to exceed these potential limits. If there is, this permit will be re -opened . If there is not, the permit will not be re -opened, but will contain weekly average limits for ammonia upon renewal. 4 The daily average dissolved oxygen effluent concentration shall not be less than 5.0 mg/L. 5 The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units. 6 Compliance shall be based upon a quarterly average of weekly samples. 7 Chronic Toxicity (Ceriodaphnia) limit at 14% with testing in March, June, September and December (see section A. (3)). There shall be no discharge of floating solids or visible foam in other than trace amounts. J Permit NC0021211 SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A. (2) PROVISIONAL WAIVER OF INSTREAM MONITORING REQUIREMENTS Instream monitoring requirements in this NPDES permit shall be provisionally waived so long as the Permittee remains a member of the Upper Cape Fear River Basin Association and the Association continues to function as approved by the Division and Environmental Management Commission. If the Permittee does not participate in the Association or if the Association ceases to function, the instream monitoring requirements in this permit become effective immediately; and the Division may reopen this permit by administrative letter to establish additional instream monitoring requirements it deems necessary to adequately characterize the effects of the discharges on water quality in the receiving stream. A. (3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 14 %. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of March, June, September and December. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: NC DENR / DWQ / Environmental Sciences Branch 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. (continued on next page) Permit NC0021211 A. (3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) (continued) Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality 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, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring. NC0021211 - City of Graham • Subject: NC0021211 - City of Graham Date: Wed, 20 Mar 2002 10:56:44 -0500 From: Stewart.Dee@epamail.epa.gov To: jackie.nowell@ncmail.net CC: Hyatt.Marshall@epamail.epa.gov, Ejimofor.Caroline@epamail.epa.gov Jackie Thank you for your 2/14/02 e-mail providing and explanation and RPA for Fluoride, Arsenic, Cadmium, Chromium, Lead, Nickel, and Selenium. Your response addresses EPA's concerns. Please note that this permit is being held by EPA Region 4 due to its lack of weekly average NH3-N limits per 40 CFR 122.45(d)(1). Additionally, this permit includes a monitoring requirement for mercury and no detection limit is recommended in the permit. EPA R4 is in discussion with NC concerning their standard use of 0.2 ug/1 as a detection limit for mercury. This value is inconsistent with EPA approved method 1669 and 1631C listing the detection limit for mercury as 0.0005 ug/l. The recent NC IG Report documented that NC should require more sensitive analytical methods as they become available. The use of a 0.2 ug/1 rather than a 0.0005 ug/1 detection limit is not consistent with the IG recommendation. NC Water Quality Standards list a mercury criterion of 0.012 ug/1 and the use of a 0.2 ug/1 detection limit is not sufficient to determine if RPA exits to exceed this criterion. An appropriate sensitive detection limit should be required per 40 CFR Part 136, 40 CFR 122.41 (j) (4) , and 40 CFR 123. 44 (c) (5) . Dee Stewart 404/562-9334 1 of 1 4/16/02 12:19 PM Add. info on Cn limit for Graham Subject: Add. info on Cn limit for Graham Date: Thu, 14 Feb 2002 12:49:27 -0500 From: Jackie Nowell <jackie.nowell@ncmail.net> Organization: NC DENR DWQ To: "Stewart.Dee@epamail.epa.gov" <Stewart.Dee@epamail.epa.gov> BCC: Dave Goodrich <Dave.Goodrich@ncmail.net> Dee, Some additional information has been provided by the City regarding the CN limit recommended in the draft permit. The RPA emailed to you earlier today contained revised CN data and indicated that there was no potential for exceedance of the water quality standard. The rationale for the change is as follows. The original NPDES RPA was done using LTMP data (8 values) submitted from 1999-2000, a CN hit of 157 ug/1 was recorded in a March 1999 sample. In May 2001, Graham submitted lab sheets that showed for that March 16, 1999 sample, the following data was reported: plant influent CN: 26 ug/1, primary clarifier effluent CN: <5 ug/1, and plant outfall effluent CN: 157 ug/1. The clarifier effluent sampling point is located before the outfall effluent, therefore the sample went from <5 ug/1 to 157 ug/1. Graham contends that there was probably a laboratory error with the sample that caused such a high value to be reported. Graham submitted DMR data from January 1992 to May 1996 (222 samples) to support their argument that the 157 ug/1 sample was the only sample that exceeded the proposed CN limit of 22 ug/1. The majority of the other values were below detection or lower than 10 ug/1. (1 value of 10 ug/1 in 1994). After review of all the information provided by Graham, NPDES concurred that a lab error probably occurred, since the 157 ug/1 datapoint was 15 times greater than the highest value reported in the past nine years.. A revised RPA was done using LTMP data back to January 1996, but with the 157 ug/1 data point considered an outlier, it was now omitted from the analysis The highest value for CN in the revised analysis is 5.39 ug/1. The results now indicate that the maximum predicted value is below the allowable concentration and the CN limit is not required. It is now the recommendation of the NPDES Unit that based on the data and information provided, the CN limit can be dropped from the draft permit and will not be in the final permit. Quarterly CN monitoring will be continued in the LTMP of the pretreatment program and data will be submitted in the DMRs that are sent to the Division. This data can be used for future RPA analysis at the next permit renewal. Please let me know if there are any questions and whether I can proceed with issuance of this permit after your review. Thanks. 1 of 1 2/14/02 3:01 PM 21211.tox.rev.xls Subject: 21211.tox.rev.xls Date: Thu, 14 Feb 2002 10:57:23 -0500 From: jackie.nowell@ncmail.net Organization: NC DENR DWQ To: Stewart.Dee@epamail.epa.gov BCC: Dave Goodrich <Dave.Goodrich@ncmail.net> Hello Dee, Attached is the RPA that was done for the City of Graham. Data was submitted on arsenic, cadmium, chromium, lead, nickel and selenium from the Long Term Monitoring Plan (LTMP) of their pretreatment program. This data was used to determine whether limits or monitoring would be required for any of these constituents. While these parameters are monitored quarterly by the discharger, they do not always submit the data on their DMRs. NPDES is now requesting that all sampled effluent data be put on the DMR form, whether or not it is required by the NPDES permit. Regarding the presence of fluoride, this parameter is not required to be sampled in the LTMP and there was no data to analyze. Graham has indicated that fluoride was marked as "may be present" based on being added to their drinking water at the water treatment plant. Their pretreatment coordinator has said that none of their SIUs have any fluoride and the only possible source would drinking water. Please let me know if any other questions.

There were several parameters listed as believed present which have NC numeric water quality standards and I did not see any data contained in the file or the certification DMR which would enable a reasonable potential determination. These parameters include: Fluoride Arsenic Cadmium Chromium Lead Nickel Selenium. Please explain how RP for a numeric NPDES permit limit was determined for these parameters. Thank you for your response. Dee Stewart EPA R4 404/562-9334 1 of 1 2/11/02 10:18 AM Comment on NPDES permit #NC0021211... of Graham WWTP in Alamance County Subject: Comment on NPDES permit #NC0021211 - City of Graham WWTP in Alamance County Date: Tue, 12 Jun 2001 12:15:35 -0400 From: Ejimofor.Caroline@epamail.epa.gov To: jackie.nowell@ncmail.net CC: dave.goodrich@ncmail.net Jackie, NC has action levels for several criteria (Cu, Zn, Ag, Cl,Fe, chlorides), instead of numeric criteria. If application data for these indicate a reasonable potential to exceed the action level instream AND there are WET test failures, the permit should be drafted with numeric limits for the parameter(s) of concern. If it's not clear that exceedance of the action level is the cause of the toxicity, the permittee is supposed to be given time to find the source(s) of toxicity and if the cause isn't determined after a date certain, numeric limits for the action level(s) kick in. If the application data show the action level to be exceeded instream and there aren't WET failures, the permit should contain monitoring for the parameter(s) of concern. Please address this comment prior to issuing the City of Graham WWTP NPDES permit.

These nine cities will not receive mass based nutrient limits in their permit until the model has been completed and reviewed. The model results are due April 2002. Existing concentration based TP limits of 2 mg/1 are in both permits. I assumed that since both cities were aware of their status, I did not have to repeat it in their letters. However, I will add an additional sentence to make it clear in the final permit letter.

Drawer 357 201 South Main Street Graham, North Carolina 27253 336) 570-6700 / Fax: (336) 570-6703 May 9, 2001 IECE HED MAY - 9 2001 DENR-WATER QUALITY POINT SOURCE BRANCH Subject: Draft NPDES Permit Permit No. NC0021211 Graham WWTP The City of Graham received the draft NPDES permit during April 2001. City staff began reviewing this document and desires to submit the following comments concerning it. 1. Under "SUPPLEMENT TO PERMIT COVER SHEET." The following changes should be made due to the current plant construction upgrade: a. Delete intermediate clarifiers. We are now operating four final clarifiers and no immediate clarifiers. b. Prior to the end of 2001, the WWTP will have two new processes: (1) Hycor Rotorary Drum Sludge Thickener and (1) Sludge Storage Unit of 0.75 million gallons. 2. Effluent limitation for Cyanide of 22 ug/I was added to the permit. The City believes that this parameter should not be listed nor limited on our permit. Also, Cyanide is typically collected by grab sample but is listed on the draft permit as composite sample. 2 We understand the reason for adding the cyanide limit was based on your evaluation using the reasonable potential analysis. Also, we understand that you were limited on the amount of data to use to perform this analysis. We have sampled effluent cyanide 222 times since January 1, 1992. There was one sample result of 157 ug/I in March, 1999. The next highest result was 10 ug/l in December 1994. Therefore, out of 222 effluent samples analyzed, only once was the proposed effluent limit violated. We are submitting this data for your review and feel it should be incorporated into the analysis. We believe the March 16, 1999 effluent sample was an anomaly. On the day that this result was obtained, cyanide was analyzed, additionally, on the plant influent and primary clarifier effluent (See attached). The results are as listed: Plant Influent Primary Clarifier Effluent Plant Effluent 26 ug/I <5 ug/I 157 ug/I These results are not logical and follow no pattern of inhibition or pass through at the POTW. One would think that the primary clarifier effluent would have the highest level of cyanide. We believe there is a strong likelihood of a laboratory error or sampling error. We believe that due to the suspect nature of this one result — IT SHOULD NOT BE USED for NPDES permitting decisions. The City of Graham does not have a Significant Industrial User that generates cyanide in their manufacturing process, nor does the City have a metal finisher or electroplating facility discharging to the WWTP. The City has had the plant effluent analyzed for toxicity 24 times since 1995. A pass result was obtained on 22 times. The two times that a failure occurred, there was no mortality of the ceria daphnia, merely a reduction in reproduction. We believe that when the above evidence is included in your review of our draft permit that you will concur that the cyanide limit is not warranted. 3 If you need additional information or clarity on our position of the draft permit, please, call either Victor R. Quick at 336.570.6700 or myself at 336.570.6721. Sincerely, David w. Lawson Plant Supervisor, City of Graham Cc: Victor R.

The 3.541CVUP discharges into Haw River, a class C NSW stream, in CPF02 subbasin. The Haw River is listed on North Carolina's 2000 303(d) list. The segment from NC Highway 87 to NC Highway 49 is listed as partially supporting its uses. The causes of impairment is fecal coliform, turbidity, and biological impairment (sediment) for a 19.2 mile stretch, with potential sources of agriculture, storm sewers and urban runoff. DWQ will develop a TMDL for fecal coliform'this segment and a management strategy for turbidity. However, the Graham WWTP discharges into the Haw River below this 303d listed segment. The 1998 biological rating for Haw River at NC 54 near Graham is Good -Fair. This segment was also rated Good -Fair in 1993 and 1989, which was an improvement from the Fair rating in August 1987. Haw River from NC 49 to a point 0.4 miles dwnstrm of Cane Creek (South side of Haw River) has a use support rating of fully supporting. Problem parameters are turbidity with the major source being nonpoint. The chemical rating from 94-98 is partially supporting. The benthos rating is Good at Highway 54; at SR1005, the rating is Good -Fair. Graham currently has an active pretreatment program with Long Term Monitoring Program. There are six significant industrial users discharging to the system. The facility has an average industrial flow of 0.633MGD (per 1996 headworks analysis). The permitted industrial flow is 0.7168 MGD. SIUs - for Graham WWTP are as follows: • BFI Medical Waste, Inc. - incineration of solid medical waste - 0.017 MGD - intermittent flow • Culp Weaving - woven fabric - 0.305 MGD- intermittent flow • Uni-Chem Hose Corp. - rubber & plastics hose - 0.015 MGD- intermittent flow • Luxfer Gas Cylinders - aluminum gas cylinders - 0.057 MGD - intermittent flow • Nannoflex - narrow elastic - 0.020 MGD - intermittent flow • G & K Services- industrial laundry - 0.072 MGD - intermittent flow Graham WWTP Fact Sheet NPDES Renewal Page 1 Graham is currently in the middle of construction for plant improvement. hydraulic expansion is involved. ATC issued in 1994 for upgrade of existing digestors with new pumps -\h\5 RZ(, • and blowers, the construction of sludge stabilization/mixing tanks, and new sludge loading w` storage. \a-\-k-(i\tiA Facility submitted letter on June 8, 2000, reporting on the progress the Town's efforts to address compliance with the Nitrogen Discharge Limits proposed for the Haw River in the CPF basin. The city has addressed nutrient removal by 1) redesigning the alum feed facilities to allow continual treatment for P removal. 2) proposed improvements to the sludge digestion and storage capabilities to allow regular sludge wasting, Additional final settling tanks will be half the current rate. Evaluation of methods to reduce the discharge from the Graham plant, included a review of land application. Also standby generators and upgrading a pump station, improve reliability and reduce the possibility of untreated discharge. In Sept. 1997, orthophosphate sampling requirement was deleted from the Graham permit because of Memorandum of Understanding with the City of Burlington. In July 1997, mercury limit was removed and twice per month monitoring was included. Existing Effluent Limits @ 2.5 MGD Qw = 3.5 MGD BOD5 = 12.0 mg/1 (summer) BOD5 = 24.0 mg/1 (winter) NH3 = 4.0 mg/1 (summer) NH3 = 8.0 mg/1 (winter) DO = 6 mg/1 TSS = 30 mg/1 Fecal Coliform = 200/ 100m1 TRC = 17 ug/1 pH = 6-9 SU Total Phosphorus = 2 mg/1 Monthly monitoring for copper and zinc. Twice per month monitoring for mercury, Chronic Toxicity P/F @ 14%; March June September December TOXICITY TESTING: Current Requirement: Chronic Toxicity P/F @ 14%; March June September December The Graham WWTP has passed the toxicity test most of the time since 1997. There were FAILs in June 1999 and June 2000. Recommend renewal of chronic toxicity test @ 14%. Checked with Aquatic Tox on any reported basis for fails. There was no info in AQ TOX suspense files. COMPLIANCE SUMMARY: Facility's compliance record since 1998 has been marked by exceedances in TSS and TP. The improvements that are currently under construction should help with meeting these limits. Graham has passed all compliance evaluation inspections. For January 2001, Qw = 1.64 MGD (approximately 46% of capacity), BOD5=1.67 mg/1, NH3=1.68 mg/1, TSS=17.9 mg/1, TN=27.6 mg/ and TP=1.15 mg/1. In 2000, Avg. Qw = 1.67 MGD (approximately 47% of capacity), BOD5=2.29 mg/1, NH3=0.28 mg/1, TSS=40.2 mg/1, TN=7.7 mg/ and TP=1. 67 mg/1. Three exceedances of the TSS limit in January, February, and March 2000. In 1999, Avg. Qw = 1.87 MGD (approximately 53% of capacity), BOD5=2.35 mg/1, NH3=0.0 mg/1, TSS=23.6 mg/1, TN=9.7 mg/ and TP=1.75 mg/1. In 1998, Avg. Qw = 1.98 MGD (approximately 56% of capacity), BOD5=3.18 mg/1, NH3=0.01 mg/1, TSS=28.6 mg/1, TN=8.7 mg/ and TP=2.13 mg/1.

INSTREAM MONITORING: Graham is a participant in the Upper Cape Fear River Basin Association and the coordinated instream monitoring effort. Individual instream monitoring requirements for DO, temperature, conductivity, and fecal coliform have been waived from the Graham permit effective April 6, 2000. A review of instream monitoring data prior to April 2000 - In April - October 1998 and 1999, instream data looked good most months, monthly instream DO averaged above 5 mg/1. Only one upstream and one downstream value reported below 5 mg/1 (August 1999). Will recommend continuation of waiver of instream monitoring for dissolved oxygen and temperature while Graham is a member of the Upper Cape Fear River Basin Association. PROPOSED CHANGES: The following modifications have been made to the permit: • Addition of effluent limitation for cyanide. RPA was based on values from 1999 - 2000 Long Term Monitoring Plan data. (Will recommend that facility report LTMP data on DMRs submitted to the Division.) Analysis indicated that cyanide should be limited based on a predicted value that would exceed the allowable concentration. Highest data value was 157 ug/1 in March 1999 . The EPA Y2 FAV criteria value of 22 ug/1 will be assigned as a limit per Division policy limits and monitoring for CN and metals (4/28/99) PROPOSED SCHEDULE FOR PERMIT ISSUANCE: Draft Permit to Public Notice: 04 / 11 / 2001 Permit Scheduled to Issue: 05/25/2001 Graham WWTP Fact Sheet NPDES Renewal Page 3 STATE CONTACT: If you have any questions on any of the above information or on the attached permit, please contact Jackie Nowell at (919) 733-5083 ext. 512.

GRAHAM SUBMITTED LAB SHEETS THAT SHOWED THAT FOR THAT MARCH 1999 SAMPLE THE FOLLOWING DATA WAS REPORTED, AN INFLUENT CN OF 26 UG/L, PRIMARY CLARIFIER EFFLUENT CN WAS <5 UG/L AND PLANT OUTFALL EFFLUENT CN OF 157 UG/L. SINCE THE CLARIFIER EFFLUENT IS LOCATED BEFORE THE OUTFALL EFFLUENT, THE SAMPLE WENT FROM <5 UG/L TO 157 UG/L. WILL CONCUR THAT THERE IS PROBABLY SOME LAB ERROR AND WILL DELETE THE CYANIDE LIMIT FROM GRAHAM'S PERMIT. GRAHAM SUBMITTED DMR DATA FROM JANUARY 1992 TO MAY 1996 (222 EFFLUENT SAMPLES) TO SUPPORT THE FACT THAT THE 157 UG/L SAMPLE WAS TIID ONLY SAMPLE THAT EXCEEDED THE PROPOSED CN LIMIT. THE MAJORITY OF THE OTHER VALUES WERE BELOW DETECTION OR <10 UG/L. WILL ALSO RECOMMEND THAT FACILITY PUT ALL LIMP DATA ON THE DMR'S SUBMITTED TO DWQ.

You informed me that your office was in the process of granting extensions to the permittees discharging into the Cape Fear River Basin. I indicated to you that the City of Graham had already completed the previously used longer application. You advised that the City may go ahead and submit that completed application even though we probably will be granted an extension. The City of Graham request renewal for NPDES permit No. NC0021211 for the operation of the City of Graham Wastewater Treatment Plant. Please find enclosed the following required items in the city's application package. 1. One original and two copies of this cover letter. 2. One signed original and two copies of the completed application. 3. Three copies of previously submitted letter showing delegated authority to Authorized Representative. 4. One signed original and two copies of the narrative description of the Sludge Management Plan. Please contact me at 336.570.6700 if you have any questions or need additional information.

The authorized representative will be the person holding the position of Treatment Plants Superintendent for the City of Graham. The person presently holding the Treatment Plant Superintendent position, Martin D. Wilson, is leaving the City of Graham. Until anew Superintendent is hired, the City Manger, Ray Fogleman, will sign as the `Permittee." Future reports required by the NPDES permits for the Water and Wastewater Facilities will be signed by the person holding the Treatment Plant Superintendent position unless that position is vacant. The "Operator in Responslle Charge (ORC)" for both the Water and Wastewater Plants is not changng at this time. The Supervisor of each fatty is designated as the plant "ORC", and they will continue to sign the reports in that capacity.

Carson, WTP Supervisor City of Graham Wastewater Treatment Plant Sludge Management Plan NPDES Permit No. NC0021211 July 25, 2000 • Wastewater Treatment Plant sludge is aerobically digested, lime stabilized, and then surface applied to a dedicated land application site. • Aerobic digestion takes place in the primary and secondary digesters (combined volume of 375,900 gallons). The digested sludge is then stabilized by adding approximately 2.7 tons of hydrated lime per 48,000 gallons of sludge (sludge pH is raised to 12.0 standard units for 2 hours and then held at 11.5 pH for an additional 22 hours). Two lime stabilization tanks (combined volume of 100,000 gallons) are utilized for this process. Sludge is then pumped to the transport trucks for delivery to the land application site. • Stabilized sludge is transported via two sealed tanker trucks to the site. The delivery vehicle used carries a copy of the Non -Discharge permit and spill control and prevention policy. Remote routes are used and equipment meets DOT standards. Drivers are trained and educated concerning operational components of the permit and receiver site procedures. All drivers have CDL license with tanker and air brake endorsements. • The land application site is dedicated city owned land. There are 89.4 acres of land that is permitted under Non -Discharge permit No. WQ0003824. Sludge is surface applied in accordance with the permit restrictions using an off -road vehicle with sealed tank. • A fescue cover crop is maintained on the fields and is harvested and used for cattle feed. Fields are maintained and crops harvested in accordance with permit requirements. • Nutrient and metal loadings and application rates are calculated and reported in accordance with WQ0003824 requirements. • All land application activities are performed in accordance with WQ0003824 requirements and 40 CFR Part 503 federal regulations.

It would seem that a combination of 1 & 2 would be most reasonable. Larry Ausley wrote: The City of Graham, a member of the UCFRBA has just had its instream monitoring waived in lieu of coalition monitoring. In its permit (NC0021211), the facility has effluent phosphorus and ortho-P monitoring required on the same days that instream monitoring for those parameters occurs (weekly P , , .) (Facility Contact -David Lawson 336-570-6721) fr'`1-i`0`l- The coalition will be sampling total-P downstream of he facility monthly and biweekly during May -Sept. The facility now doesn't have that day "hook" for sampling their effluent. Let me propose three approaches to resolve this gap: 1 of 2 5/30/00 4:33 PM Graham's permit requirments t 1) the facility has offered to keep up the same amount of effluent sampling (weekly P and 3x/week ortho-P Jun -Sep) but just spread through the week. 2) have the coalition contractor (Burlington Research) call the facility and let them know instream sampling date ahead of time (get P- and ortho-P effluent samples same day as instream but less often than under the permit) 3)combination of 1 and 2 so that at least SOME of #1 sampling occurs on the same day as notified like #2. Please respond with a preference or alternative and also a thought on how to handle this administratively and I'll be glad to expedite the solution. Thanks Larry W.

Drawer 357 201 South Main Street Graham, North Carolina 27253 Tel: (336) 570-6700 / Fax: (336) 570-6703 June 8, 2000 Mr. Bill Reid Supervisor, Point Source Branch Water Quality Section NCDENR-DWQ PO Box 29535 Raleigh, NC 27626-0535 Re: Graham, North Carolina WWTP Nitrogen Discharge Limit Dear Mr. Reid: This letter is to report on progress of the City of Graham's efforts to address compliance with the Nitrogen Discharge Limits proposed for the Haw River in the Cape Fear River Basin. This progress report is in response to NCGS 143- 215.1B(d)(5). It is our expectation that this information will satisfy the requirements for nutrient discharge compliance set forth by NCGS 143-215.1. The Division of Water Quality gave full approval to the Graham 201 Facility Plan which recommended wastewater treatment plant improvements to address hydraulic capacity, solids handling, and flood prevention. The City received Authorization to Construct the recommended improvements project. Construction is in progress with an expected completion date of November 2001. We feel that the improvements will address the following: 1. [143-215.1 B(d)(2)] Evaluate and optimize the operations of the City of Graham WWTP in order to reduce nutrient loading. A. The improvements address nutrient removal by redesigning the alum feed facilities to allow continual treatment for phosphorus removal. Specifically, the alum feed point has been relocated and new storage and feed equipment are provided. B. Phosphorus removal can be increased by feeding alum on a continuous basis. 2. [143-215.1B(d)(3)] Evaluate methods to reduce the total mass Toad of waste that is discharged from the City of Graham WWTP and determine whether the methods are cost effective. A. The proposed improvements to the sludge digestion and storage capabilities will allow regular sludge wasting resulting in the ability to control MLSS and F/M ratio. This is expected to improve treatment performance. B. With additional final settling tanks, the surface overflow rate will be half the current rate. Performance will also be enhanced by decreasing the solids loading by reducing the MLSS concentration. June 8, 2000 Page Two 3. [143-215.1 B(d)(4)] Evaluate methods to reduce the discharge of treated effluent from the Graham WWTP and determine whether the methods are cost effective. A. Land application of effluent was evaluated in the 201 Facility Plan and determined not to be cost effective. B. Although Infiltration/Inflow was found to be within limits prescribed by the regulations during the Facility Planning process, the improvements include standby generators at several of the pumping stations and upgrading Backcreek Pumping Station No. 1, thus improving reliability and therefore reducing the possibility of untreated discharge. In addition, Graham is currently developing a calibrated nutrient response model in conjunction with Burlington, Greensboro, Mebane, Orange Water and Sewer Authority, Pittsboro and Reidsville [143-215.1 B(d)(1)]. We trust this satisfactorily addresses nutrient discharge compliance concems the Commission may have for the Graham WWTP facility. Please contact us if you have any questions or comments. 62,d Victor Quick Treatment Plants Superintendent c: Lary Coble, Winston-Salem Regional Office, NCDENR-DWQ David Hamilton, FPS
