The weekly average limit is 25.5 Mg/I and our average came in at 36.076 Mg/I. We will be okay on the monthly average which is 17 Mg/l. On 9/29/16 we were having some issues with the Sodium Bisulfite system. As you know this is the De -Chlorinating chemical that we use to manage the chlorine residual at the final effluent. We were collecting Toxicity samples on that morning and as the operator on duty was getting the de-chlor system back up running, the effluent sampler came on and collected a composite sample with a big slug of the de -chlorinating chemical in the sample. Sodium Bisulfite is low in pH which affected the toxicity sample, BOD and COD samples on the effluent. Toxicity and BOD we have parameters for but the COD we just monitor. The effluent COD for that sample was 252 Mg/I and the influent COD was 195 Mg/l. The effluent BOD for that day was 173 Mg/I and the influent BOD was 88.6 Mg/I. All of the days prior to that sample day and after that sample day have been in the single digits for the BOD sample. Please advise.

April 25, 2016 RECEIVED/NCDENR/DWR APR 2 7 2016 Subject: NPDES Electronic Reporting Requirements and Sixty Day Notice of Minor Modification of the NPDES Permit Fourth Creek WWTP NPDES Permit Number: NCO031836 Dear NPDES Permittee: WOROS MOORESVILLE REGIONAL OFFICE The U.S. Environmental Protection Agency (EPA) recently published the National Pollutant Discharge Elimination System (NPDES) Electronic Reporting Rule. The rule requires NPDES regulated facilities to report information electronically, instead of filing written paper reports. The rule does not change what information is required from facilities. It only changes the method by which information is provided (i.e., electronic rather than paper -based). EPA is phasing in the requirements of the rule over a 5-year period. The two phases of the rule, and their key milestones, are: • Phase 1—Starting on December 21, 2016, regulated entities that are required to submit Discharge Monitoring Reports (DMRs) will begin submitting these reports electronically. If you are currently reporting your DMR data electronically using eDMR, then you simply need to continue reporting in the same way as you are now. The key change is that, starting on December 21, 2016, electronic reporting of DMRs will be required, instead of voluntary. • Phase 2—Starting on December2l, 2020, regulated entities that are required to submit certain other NPDES reports will begin submitting these reports electronically. Reports covered in the second phase include Notices of Intent to discharge in compliance with an NPDES general permit, Sewer Overflow/Bypass Event Reports, and a number of other NPDES program reports. For more information on EPA's NPDES Electronic Reporting Rule, visit htt_p://www2.epa.goy/compliance/final-national-pollutant-discharge-elimination-system-npdes- electronic-reporting-rule. For more information on electronic reporting to NC DWR, visit http://deg.nc.gov/about/divisions/water-resources/edmrinpdes-electronic-reporting or contact Vanessa Manuel at 919-807-6392 or via email at Vanessa.Manuel@ncdenr.gov. State of North Carolina I Environmental Quality I Water Resources 1617 Mail Service Center I Raleigh, North Carolina 27699-1617 919 807 6300 Sixty Days' Notice of Minor Modification of the Subject NPDES Permit The NPDES Electronic Reporting Rule requires authorized NPDES programs to incorporate electronic reporting requirements into NPDES permits beginning December 21, 2015. Under the new rule, the electronic reporting process supersedes the paper reporting process outlined in your existing permit. To bring your permit up-to-date with the new reporting requirements, this letter serves to notify you that in sixty days your NPDES permit will be modified to incorporate the new electronic reporting requirements. The modification will require electronic reporting in place of paper -based reporting. Electronic reporting will be required beginning as indicated above for Phases 1 and 2 reporting. Please attach the enclosed NPDES Permit Standard Conditions Part /// —Addendum to your permit. This permit modification becomes effective on August 1, 2016.

Page# Bell, Wes From: Andy Smith <asmith@statesvillenc.net> Sent: Wednesday, August 26, 2015 11:44 AM To: Bell, Wes Cc: jhudson@statesvillenc.net; Jerry Byerly Subject: Disinfection Process Wes, per our conversation on 8/25/15. The 4th Creek WWTP, permit #NC0031836, as of Saturday 8/22/15 stopped using chlorine gas for disinfection purposes. The current supplier of chlorine gas for the City of Statesville could no longer meet our needs. As well, it has become more difficult for the few remaining suppliers of chlorine gas in ton cylinders to quote prices and supply us with the proper amount in inventory. Based on these issues, the City of Statesville made the switch to Sodium Hypochlorite @ 12% for the disinfection process. The WWTP is still able to maintain fecal coliform counts well below the permit limit. We do not foresee any problems due to this change. If you need more information regarding this, please advise. Thanks.

Box 1111 Statesville, North Carolina 28687 Subject: Holiday Reporting Guidance December 2010 Monthly Monitoring Report City of Statesville Fourth Creek WWTP NPDES Permit No. NCO031836 Iredell County, NC Dear Mr. Sides: A review of the December 2010 Discharge Monitoring Report (DMR) revealed a reporting deficiency, which resulted in your permit being flagged for monitoring violations of BOD, total residual chlorine, fecal coliform, dissolved oxygen, ammonia -nitrogen, TSS, temperature, pH, and conductivity in the Division of Water Quality's compliance database as noted in the attached document. The following deficiency was found on the subject DMR - holidays not clearly marked. To prevent the generation of monitoring violations, the permittee or their designee (ORC) must enter the letter "H" in each parameter block (that was not sampled) on a date designated as "holiday time" by the permittee. "Holiday" may also be written across multiple parameter blocks if more than one parameter had reduced monitoring or if more than one day was included in the holiday celebration. Designating "H" or "Holiday" allows the Division's data entry staff to correctly code the holiday and trigger the Division's compliance database to calculate a reduced number of monitoring requirements during this abbreviated monitoring week. The submission of an amended DMR is required to address the noted monitoring deficiencies during the week ending January 1, 2011. Please submit an amended December 2010 Discharge Monitoring Report by June 3, 2011. Send two copies of the amended DMR to Central Files, Division of Water Quality, 1617 Mail Service Center, Raleigh, North Carolina 27699-1617.

This assessment is based upon the following facts: A review has been conducted of the self - monitoring data reported for August 2010. This review has shown the subject facility to be in violation of the monitoring requirements found in NPDES Permit No. NC0031836. The violations that occurred are summarized in Attachment A to this letter. Based upon the above facts, I conclude as a matter of law that the City of Statesville violated the terms, conditions, or requirements of NPDES Permit No. NCO031836 and North Carolina General Statute (G.S.) 143-215. 1 (a)(6) in the manner and extent shown in Attachment A. A civil penalty may be assessed in accordance with the maximums established by G.S. 143-215.6A(a)(2). Based upon the above findings of fact and conclusions of law, and in accordance with authority provided by the Secretary of the Department of Environment and Natural Resources and the Director of the Division of Water Quality, I, Robert B. Krebs, Surface Water Protection Regional Supervisor for the Mooresville Region, hereby make the following civil penalty assessment against the City of Statesville: Mooresville Regional Office Location: 610 East Center Ave., Suite 301 Mooresville, NC 28115 One Phone: (704) 663-16991 Fax: (704) 663-60401 Customer Service: 1-877-623-6748 NorthCarolina Internet: http:llportal.ncdenr.orglweblwq e., c,,.,..i n....,..,,..,a„ Aq:......K.,.. �..,:.,..

TOTAL CIVIL PENALTY Enforcement costs. TOTAL AMOUNT DUE Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken into account the Findings of Fact and Conclusions of Law and the factors set forth at G.S. 143 B-2 82. 1 (b), which are: (1) The degree and extent of harm to the natural resources of the State, to the public health, or to private property resulting from the violations; (2) The duration and gravity of the violations; (3). The effect on ground or surface water quantity or quality or on air quality; (4) The cost of rectifying the damage; (5) The amount of money saved by noncompliance; (6) Whether the violations were committed willfully or intentionally; (7) The prior record of the violator in complying or failing to comply with programs over which the Environmental Management Commission has regulatory authority; and (8) The cost to the State of the enforcement procedures. Within thirty days of receipt of this notice, you must do one of the following: 1. Submit payment of the penalty: Payment should be made directly to the order of the Department of Environment and Natural Resources (do not include waiver form). Payment of the penalty will not foreclose further enforcement action for any continuing or new violation(s). Please submit payment to the attention of: Point Source Compliance/Enforcement Unit Division of Water Quality 1617 Mail Service Center Raleigh, North Carolina 27699-1617 N' 2. Submit a written request for remission including a detailed justification for such request: Please be aware that a request for remission is limited to consideration of the five factors listed below as they may relate to the reasonableness of the amount of the penalty assessed. Requesting remission is not the proper procedure for contesting whether the violation(s) occurred or the accuracy of any of the factual statements contained in the civil penalty assessment document. Because a remission request forecloses the option of an administrative hearing, such a request must be F_ accompanied by a waiver of your right to an administrative hearing and a stipulation that no factual or legal issues are in dispute. Please prepare a detailed statement that establishes why you believe the civil penalty should be remitted, and submit it to the Division of Water Quality at the address listed below. In determining whether a remission request will be approved, the following factors shall be considered: (1) whether one or more of the civil penalty assessment factors in G.S. 143B-282.1(b) were wrongfully applied to the detriment of the petitioner; (2) whether the violator promptly abated continuing environmental damage resulting from the violation; (3) whether the violation was inadvertent or a result of an accident; (4) whether the violator had been assessed civil penalties for any previous violations; or (5) whether payment of the civil penalty will prevent payment for the remaining necessary remedial actions. Please note that all information presented in support of your request for remission must be submitted in writing. The Director of the Division of Water Quality will review your evidence and inform you of his decision in the matter of your remission request. The response will provide details regarding case status, directions for payment, and provision for further appeal of the penalty to the Environmental Management Commission's Committee on Civil Penalty Remissions (Committee). Please be advised that the Committee cannot consider information that was not part of the original remission request considered by the Director. Therefore, it is very important that you prepare a complete and thorough statement in support of your request for remission. In order to request remission, you must complete and submit the enclosed "Waiver of Right to an Administrative Hearing and Stipulation of Facts" form within thirty (30) days of receipt of this notice. The Division of Water Quality also requests that you complete and submit the enclosed "Justification for Remission Request." Both forms should be submitted to the following address: Point Source Compliance/Enforcement Unit Division of Water Quality 1617 Mail Service Center Raleigh, North Carolina 27699-1617 W' 3.

Record Keeping — On 4/08/10 Effluent fecal coliform was reported as 2 and should have been reported as 10. 4110110 Influent TSS was reported as 135 mg/I and should have been reported as 157 mg/l. The ORC mistakenly entered the wrong data for these dates. While these values were entered in error, neither number would have represented a permit violation had the correct number been reported originally. The April 2010 DMR for the Effluent sample does not reflect a visitation on a non-existent day. The date in question is 4/31/10, which is a non-existent day and there is nothing logged in for that day for visitation or sample collection. An amended April 2010 DMR has been sent to the Central Office in Raleigh NC. • Based on the information offered as a response above, we contest the statement that the April 2010 DMR shows an operator visit on a non-existent day. • Laboratory - The Fourth Creek WWTP lab staff collected samples for the Effluent Pollutant Scan in April 2010. During the Annual Inspection it was noted that some of the samples were collected incorrectly. Since this extensive array of tests is required to be completed on an Annual basis and since the only reference to annual in the permit definition is "during a calendar year" we contend that the sample we plan to collect in October will keep us in compliance with the permit. • Based on the above information above we contest any violation or penalty based on the April 2010 Effluent Pollutant Scan. i V. M. fax 1111 •-3tatesuille. North Tarohna 28687 Influent Sampling — The influent sampler tubing is changed out at least quarterly. Sampler tubing is exposed to the harshest of elements; it carries raw sewage several times per day to the sample collection bottle. The appearance of the tubing begins to degrade almost immediately upon installation. Although the sample tubing appears to be dirty, it is an influent sampler and will give the appearance of dirty tubing within a short amount of time after being changed. We can find no specific requirement in the permit to change sampler tubing on any different interval than our current quarterly schedule. Manual of Practices 11 states that" Regular cleaning of the samplers and the lines leading to them is necessary to prevent biological fouling and alteration of the sample' . We contend that the fact that the sampler functions without fail and that our sample results are well within expected normal ranges for influent wastewater further shows that the sampler tubing was serviceable and did not rise to the level of any kind of violation. • For reasons stated above we strongly disagree that the sampler tube was dirty on the day of the inspection Effluent Sampling — The effluent sampler tubing is changed out at least quarterly. This tubing is exposed to the elements immediately upon being put in service. The opacity of the material will begin to degrade immediately. While the tubing was not clear it has not affected the integrity of the final effluent sample. This is evident by the data in the monthly DMR's that are sent in to the state regulatory office. We can find no specific requirement in the permit to change sampler tubing on any different interval than our current quarterly schedule. Manual of Practices 11 states that" Regular cleaning of the samplers and the lines leading to them is necessary to prevent biological fouling and alteration of the sample" . We contend that the fact that the sampler functions without fail and that our sample results are within permitted limits shows that the sampler tubing was serviceable and did not rise to the level of any kind of violation. • For reasons stated above we strongly disagree that the sampler tube was dirty on the day of the inspection • Solids Handling — After careful evaluation, the Fourth Creek WWTP operations staff have determined that installing a concrete barrier between the cake sludge and the curbing of the sludge pad should be sufficient for containment. This sludge is dumped on the pad for the purpose of contracted land application and the operators have tried to maintain about a 12" buffer from the curb where the sludge is dumped. Since the issue of containment of the sludge has been brought to my attention, the Fourth Creek WWTP staff will proceed with cleaning the ditch area up and installing the barrier as mentioned. Given the reasons we've stated in the letter for questioning the alleged violations, we respectfully request a review of the NOV. Please call us if you need more information. We appreciate your consideration and realize you understand how important this matter is to all involved.

Sullins Dee Freeman Governor Director Secretary JUN 21 2010 June 21, 2010 Mr. Joe Hudson City of Statesville P.O. Box 1111 Statesville, North Carolina 28687 Subject: Comments on Draft NPDES Permit Permit NCO031836 Fourth Creek WWTP Iredell County Dear Mr. Hudson: We received Statesville's response to my letter dated April 5, 2010. Statesville suggests that the timeframe in the Footnotes for mercury and phenols be revised to 27 months. This would allow Statesville 18 months to comply with the limits after the new data is submitted and the RPA for each parameter, reevaluated. When a permit is issued with a new limitation, additional time for compliance is not put in the permit unless the permittee submits a detailed compliance schedule on actions (ie. construction of additional treatment) to be taken to achieve the new limitation. Generally, a permittee can receive a 12 to 18 month compliance schedule to address the collection of additional data so a new reasonable potential analysis can be performed. If the new RPA results in the limit becoming effective, the facility then has time to proceed with additional mitigative measures and/or propose a permit modification if more time is needed and a new compliance schedule is necessary. The Division maintains that 18 months is sufficient time for this process to occur. Note that the 18 months for the Total Phenols limit does not start until the facility becomes subject to the 6 MGD Effluent Limitations and Monitoring Requirements listed under Section A(2). Therefore, if sampling is initiated and submitted along with the mercury sampling while Fourth Creek is subject to the 4 MGD Effluent Limitations, the facility will have sufficient time to investigate the source of phenols. We would like to proceed with the issuance of this permit. The final permit will be issued on June 28th with all the corrections identified in the letter sent to you on April 5, 2010. If you do not believe this will be satifactory please call and discuss this matter with me as soon as possible; however, it may be necessary for the Division to proceed without Statesville's concurrence on this issue. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Sullins Dee Freeman Director Secretary June 21, 2010 Mr. Joe Hudson City of Statesville P.O. Box 1111 Statesville, North Carolina 28687 Subject: Comments on Draft NPDES Permit Permit NCO031836 Fourth Creek WWTP Iredell County Dear Mr. Hudson: We received Statesville's response to my letter dated April 5, 2010. Statesville suggests that the timeframe in the Footnotes for mercury and phenols be revised to 27 months. This would allow Statesville 18 months to comply with the limits after the new data is submitted and the RPA for each parameter, reevaluated. When a permit is issued with a new limitation, additional time for compliance is not put in the permit unless the permittee submits a detailed compliance schedule on actions (ie. construction of additional treatment) to be taken to achieve the new limitation. Generally, a permittee can receive a 12 to 18 month compliance schedule to address the collection of additional data so a new reasonable potential analysis can be performed. If the new RPA results in the limit becoming effective, the facility then has time to proceed with additional mitigative measures and/or propose a permit modification if more time is needed and a new compliance schedule is necessary. The Division maintains that 18 months is sufficient time for this process to occur. Note that the 18 months for the Total Phenols limit does not start until the facility becomes subject to the 6 MGD Effluent Limitations and Monitoring Requirements listed under Section A(2). Therefore, if sampling is initiated and submitted along with the mercury sampling while Fourth Creek is subject to the 4 MGD Effluent Limitations, the facility will have sufficient time to investigate the source of phenols. We would like to proceed with the issuance of this permit. The final permit will be issued on June 28th with all the corrections identified in the letter sent to you on April 5, 2010. If you do not believe this will be satifactory please call and discuss this matter with me as soon as possible; however, it may be necessary for the Division to proceed without Statesville's concurrence on this issue. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Toxicity Reporting Corrected or Amended Reports 6. Contacts I. Facility Information 1. NPDES Permit No. - Number issued by the Division of Water Quality consisting of the letters "NC" followed by a seven digit number. Information from non -discharge facilities should not be reported on the MR series of forms. 2. Discharge No. - Three -digit number which corresponds to the effluent pipe for which the data are being reported (i.e., 001, 002, 003, etc.). Numbers are found within the NPDES permit. 3. Facility Name - Name of the facility as it appears on the NPDES permit. 4. Class - The class of the facility as designated by the Water Pollution Control System Operators Certification Commission. The rating will be either 0, I, II, III or IV. You should enter the water quality classification of the receiving stream in this space. 5. County - County in which the discharge outfall is located. 6. Operator In Responsible Charge -The printed name of the certified WWTP operator designated as operator in responsible charge. Unrated (class 0) facilities do not require an operator in responsible charge. 7. Grade - Certificate grade of the operator in responsible charge as awarded by the Water Pollution Control System Operators Certification Commission. 8. Certified Laboratory - Name of the certified laboratory (-ies) performing analyses (if applicable). 9. Person(s) Collecting Samples - Printed name of the individual who collected the sample for which the data was reported. In the case of several individuals, please specify as a group name, such as "operators" or "staff," etc. 10. Signature Of Operator In Responsible Charge- Dated signature of the operator in responsible charge. Each month's report must include an original signature in ink. Copies are not acceptable. I1. Data Reporting 1. Operator Arrival Time -Record the time of arrival of a certified operator using a 2400 clock value. If the facility is staffed by operators 24 hours a day, record the arrival time of the 1 st shift operator. 2. Operator Time On Site - Record the number of hours spent by certified operators at the facility. If the facility is staffed on all three shifts, enter "24." If more than one operator is on duty at the same time, this value is not the sum of all hours worked by the operators, but the total number of hours the facility was staffed. 3. ORC On Site? - Record yes (Y) or no (N) as to whether the designated ORC visited the site on that date. If the designated backup operator served as ORC on a particular day, record "B" in this column for that date. It is also appropriate to record "H" in the cell if the date is a legal holiday. 4. Data - Enter the analytical results for each sample under the appropriate parameter code in the row that corresponds to the day upon which the sample was taken. Please note that Flow should always be reported as a decimal number (do not use scientific notation) in units of millions of gallons per day (MGD), unless the permit states otherwise. 5. Parameter Codes - Codes for the more commonly monitored parameters can be found on the back of form MR-1 or MR- 1.1. A complete list of parameter codes can be found on the NPDES website. 6. Units of Measurement - All data values must be accompanied by corresponding units of measurement, noted at the top of the data column for the particular parameter. If your permit contains a numeric limit for any parameter, then the reporting units must be the same units of measurement of that limit. If your reporting units are other than those on the pre-printed form, the printed units should be marked out and the reporting units be clearly designated at the top of the column. 7. Additional Parameters - Enter the appropriate parameter code, name of the parameter and units of measurement in the space provided. 8. Average, Maximum, Minimum - Enter the average, maximum and minimum values for the results recorded in the data column. Please note no average is to be calculated for pH. Any average for Fecal Coliform is to be calculated as a geometric mean. If you are uncertain about how to calculate the geometric mean, please contact your local DWQ Regional Office or a member of the NPDES Compliance/Enforcement Unit staff at (919) 733-5083. If only one value is reported for a parameter during the reporting month, that value should be reported as the average, maximum and minimum. 9. Sample Type - Enter the sample description in each column for which data is being reported. Enter the letter "C" for composite or the letter "G" for grab. 10. Monthly Limit - Enter the monthly limit for each parameter as found in the current NPDES permit, Special Order by Consent or Judicial Order by Consent. III. Facility Status Information 1. Facility Status - Mark the appropriate box to show whether facility was compliant or noncompliant with regard to permit, SOC or JOC requirements. If noncompliant, use the comment section to explain in detail the course of action taken or to be taken to achieve compliance. 2. Signature of Permittee - Record the name of the permittee or his or her authorized agent (printed or typed), the dated signature of that person and a mailing address and phone number at which he or she may be reached during working hours. If someone other than the permittee is to be the signatory, the requirement noted by the double asterisk "**" must be met. Also record the expiration date of the current permit in this section. While this is not on the form, you may also wish to provide an e-mail address in this space that can provide the Division with another avenue of communication. IV. Stream Monitoring Information 1. Stream - Name of the stream from which the upstream or downstream monitoring samples are taken. 2. Location - Location of the site on the stream from which the sample was taken. This may be recorded as a distance (e.g. "100 feet upstream of outfall") or a specific location (e.g. "S.R. 1111" ). V. General 1. Submitting Reports - An original and one copy of each month's monitoring report is required to be submitted to the Division of Water Quality's Central Files office (address listed on form MR-1) and must be received by the Division within thirty (30) days after the end of the month for which the report is made. 2. Appearance - Forms must be completed in ink. Please make all entries on forms legible. All information other than signatures must be printed or typed. If you fill out forms by hand, please make sure the originals are completed in ink and that all entries are legible. Copies of the original report must also be readable and must include a reproduction of the backside of the effluent reporting form containing the permittee's certification. If you utilize a computer -generated report, you must also ensure that the report is legible and that proper copies are made. DWQ will notify if you are the user of a form that is deemed deficient and will advise you of what modifications need to be made. 3. Calculations (a) Averages. All averages are to be calculated as the arithmetic mean of the recorded values with the exception of that of Fecal Coliform, which is to be calculated as a geometric mean. If you are uncertain about how to calculate the geometric mean, please contact your local DWQ Regional Office or a member of the NPDES Compliance/Enforcement Unit staff at (919) 733-5083. (b) Use of "less than" values. For calculation purposes only, recorded values of less than a detectable limit (< #.##) may be considered to equal zero (0) for all parameters except Fecal Coliform, for which values of "less than" may be considered to be equal to one (1). Values of results which are less than a detectable limit should be reported in the daily cells using the "less than" symbol (<) and the detectable limit used during the testing (or the value with appropriate unit conversion). Please note there is never a case when an average would need to be recorded along with a "less than" symbol. (c) Use of "greater than" values. Such values are only expected (and then only infrequently) in the reporting of Fecal Coliform and BOD. If a "greater than" value is reported, the numeric portion of the value should be sufficiently high so as to make the facility aware of the extent of any problems with treatment efficiency. Upon receipt of "greater than" testing results, a facility should consult its laboratory to see if changes in testing procedure need to be made in order to • . get discreet values from the analysis. For calculation purposes only, the numeric portion of the value must be used to calculate either an arithmetic or geometric mean. 4. Enforcement - Failure to comply with any of the requirements listed above may result in the facility being issued a Notice of Violation or being subject to other appropriate enforcement action. 5. Order of Report Forms-DMR submittals typically include the results of monitoring of the facility's effluent, its influent and its receiving stream. It is requested that'for any DMR, the report be bound with the Effluent page(s) (DWQ form MR-1 or MR- 1.1) on top, followed by the Influent page (form MR-2, if influent monitoring is required) and finally the Upstream/Downstream page (form MR-3). 6. Number of Reports -You are required to submit the original and one copy of the report to DWQ. Each copy should be a discreet report for the month, put together in the order described above. 7. Multiple Submittals -School systems and contract operations, please take note of this request. If you submit reports for multiple permits within one mailing, please bind together the submittals (original and one copy) for the various facilities. Please do not segregate the reports into any other type of organization (e.g., binding together all effluent or stream monitoring pages). To do so will cause reports to be taken apart and placed together properly, which slows processing and introduces opportunity for mistakes to be made. If you send many DMRs in one envelope, it is advisable that you send a summary sheet along with the DMRs that lists what reports are contained in the package. 8. Permits for Other Program Areas -Please note that this discussion pertains to submittal of DMRs required of NPDES permittees (point source discharge pipes to streams). You may have permits for activities in other program areas such as DWQ's non discharge program (wastewater spray irrigation or land application of residuals) or the Division of Environmental Health's public water supply program (drinking water). Please consult those permits for instructions for their submittal. It is not advisable to submit any other reports along with your DMR submittals. 9. Toxicity Reporting -Some permittees will have monitoring requirements for Toxicity within their permits. Please be aware that this parameter has a dual reporting requirement. Results of toxicity testing should be reported on DMR forms, but the toxicity testing results forms must be submitted to the Aquatic Toxicity Unit at the address listed below. Aquatic. Toxicology Unit DWQ Environmental Sciences Branch 1621 Mail Service Center Raleigh, NC 27699-1621 10. Corrected or Amended Reports -In the event that you omit or erroneously report data on a DMR, the information should be updated with the submittal of an amended report. To best handle the amended data, the following procedure is recommended: 1. Regenerate or make a copy from your files of the DMR previously submitted to DWQ. 2. Make changes to the individual data points on the form, including updated summary information. 3. Initial and highlight changes to the original submittal. 4. At the top of the reporting page, write very conspicuously: "Amended Report" or "Corrected Report." 5. Provide a short cover page describing the changes to the DMR or note changes in the comment area on the back of the MR-1 form. Use of this procedure will be a great help to DWQ's data entry staff. Without specifically identifying changes on the DMR, each data point must be evaluated between the original and amended reports to ensure the values in our database are correct. Calling attention to just those values that are changed both speeds up our processes and decreases the possibility for errors to be made. 11. Contacts-DWQ deals with a tremendous number of permitted entities that may be experiencing their own changes involving administration and personnel. In dealing with NPDES permit matters, DWQ must deal with only one representative of the permitted facility (someone with authority to see that changes are made at the facility if they are necessary) in order to be effective. You are encouraged to keep DWQ informed of any updates as to the person responsible for the permit, addresses or phone numbers in order to facilitate the best possible communication between our two organizations. This can be done by sending an e-mail to our Unit or by using the back of the MR-1 form under the pern ittee certification section. Regulations regarding who may be deemed responsible for a permit and who may sign as the "permittee" on the DMR can be found (respectively) in the North Carolina Administrative Code in sections 15A NCAC 2H .106(e) and 15A NCAC 2B .0506 (b)(2). r, \N ,q rF Michael F.

Toxicity Reporting Corrected or Amended Reports 6. Contacts I. Facility Information 1. NPDES Permit No. - Number issued by the Division of Water Quality consisting of the letters "NC" followed by a seven digit number. Information from non -discharge facilities should not be reported on the MR series of forms. 2. Discharge No. - Three -digit number which corresponds to the effluent pipe for which the data are being reported (i.e., 001, 002, 003, etc.). Numbers are found within the NPDES permit. 3. Facility Name - Name of the facility as it appears on the NPDES permit. 4. Class - The class of the facility as designated by the Water Pollution Control System Operators Certification Commission. The rating will be either 0, I, II, III or IV. You should enter the water quality classification of the receiving stream in this space. 5. County - County in which the discharge outfall is located. 6. Operator In Responsible Charge -The printed name of the certified WWTP operator designated as operator in responsible charge. Unrated (class 0) facilities do not require an operator in responsible charge. 7. Grade - Certificate grade of the operator in responsible charge as awarded by the Water Pollution Control System Operators Certification Commission. 8. Certified Laboratory - Name of the certified laboratory (-ies) performing analyses (if applicable). 9. Person(s) Collecting Samples - Printed name of the individual who collected the sample for which the data was reported. In the case of several individuals, please specify as a group name, such as "operators" or "staff," etc. 10. Signature Of Operator In Responsible Charge- Dated signature of the operator in responsible charge. Each month's report must include an original signature in ink. Copies are not acceptable. II. Data Reporting 1. Operator Arrival Time -Record the time of arrival of a certified operator using a 2400 clock value. If the facility is staffed by operators 24 hours a day, record the arrival time of the 1 st shift operator. 2. Operator Time On Site - Record the number of hours spent by certified operators at the facility. If the facility is staffed on all three shifts, enter "24." If more than one operator is on duty at the same time, this value is not the sum of all hours worked by the operators, but the total number of hours the facility was staffed. 3. ORC On Site? - Record yes (Y) or no (N) as to whether the designated ORC visited the site on that date. If the designated backup operator served as ORC on a particular day, record "B" in this column for that date. It is also appropriate to record " H" in the cell if the date is a legal holiday. 4. Data - Enter the analytical results for each sample under the appropriate parameter code in the row that corresponds to the day upon which the sample was taken. Please note that Flow should always be reported as a decimal number (do not use scientific notation) in units of millions of gallons per day (MGD), unless the permit states otherwise. 5. Parameter Codes - Codes for the more commonly monitored parameters can be found on the back of form MR-1 or MR- 1.1. A complete list of parameter codes can be found on the NPDES website. 6. Units of Measurement - All data values must be accompanied by corresponding units of measurement, noted at the top of the data column for the particular parameter. If your permit contains a numeric limit for any parameter, then the reporting units must be the same units of measurement of that limit. If your reporting units are other than those on the pre-printed form, the printed units should be marked out and the reporting units be clearly designated at the top of the column. 7. Additional Parameters - Enter the appropriate parameter code, name of the parameter and units of measurement in the space provided. 8. Average, Maximum, Minimum - Enter the average, maximum and minimum values for the results recorded in the data column. Please note no average is to be calculated for pH. Any average for Fecal Coliform is to be calculated as a geometric mean. If you are uncertain about how to calculate the geometric mean, please contact your local DWQ Regional Office or a member of the NPDES Compliance/Enforcement Unit staff at (919) 733-5083. If only one value is reported for a parameter during the reporting month, that value should be reported as the average, maximum and minimum. 9. Sample Type - Enter the sample description in each column for which data is being reported. Enter the letter "C" for composite or the letter "G" for grab. 10. Monthly Limit - Enter the monthly limit for each parameter as found in the current NPDES permit, Special Order by Consent or Judicial Order by Consent. III. Facility Status Information 1. Facility Status - Mark the appropriate box to show whether facility was compliant or noncompliant with regard to permit, SOC or JOC requirements. If noncompliant, use the comment section to explain in detail the course of action taken or to be taken to achieve compliance. 2. Signature of Permittee - Record the name of the permittee or his or her authorized agent (printed or typed), the dated signature of that person and a mailing address and phone number at which he or she may be reached during working hours. If someone other than the permittee is to be the signatory, the requirement noted by the double asterisk "**" must be met. Also record the expiration date of the current permit in this section. While this is not on the form, you may also wish to provide an e-mail address in this space that can provide the Division with another avenue of communication. IV. Stream Monitoring Information 1. Stream - Name of the stream from which the upstream or downstream monitoring samples are taken. 2. Location - Location of the site on the stream from which the sample was taken. This may be recorded as a distance (e.g. "100 feet upstream of outfall") or a specific location (e.g. "S.R. 1111 "). V. General 1. Submitting Reports - An original and one copy of each month's monitoring report is required to be submitted to the Division of Water Quality's Central Files office (address listed on form MR-1) and must be received by the Division within thirty (30) days after the end of the month for which the report is made. 2. Appearance - Forms must be completed in ink. Please make all entries on forms legible. All information other than signatures must be printed or typed. If you fill out forms by hand, please make sure the originals are completed in ink and that all entries are legible. Copies of the original report must also be readable and must include a reproduction of the backside of the effluent reporting form containing the permittee's certification. If you utilize a computer -generated report, you must also ensure that the report is legible and that proper copies are made. DWQ will notify if you are the user of a form that is deemed deficient and will advise you of what modifications need to be made. 3. Calculations (a) Averages. All averages are to be calculated as the arithmetic mean of the recorded values with the exception of that of Fecal Coliform, which is to be calculated as a geometric mean. If you are uncertain about how to calculate the geometric mean, please contact your local DWQ Regional Office or a member of the NPDES Compliance/Enforcement Unit staff at (919) 733-5083. (b) Use of "less than" values. For calculation purposes only, recorded values of less than a detectable limit (< #.##) may be considered to equal zero (0) for all parameters except Fecal Coliform, for which values of "less than" may be considered to be equal to one (1). Values of results which are less than a detectable limit should be reported in the daily cells using the "less than" symbol (<) and the detectable limit used during the testing (or the value with appropriate unit conversion). Please note there is never a case when an average would need to be recorded along with a "less than" symbol. (c) Use of "greater than" values. Such values are only expected (and then only infrequently) in the reporting of Fecal Coliform and BOD. If a "greater than" value is reported, the numeric portion of the value should be sufficiently high so as to make the facility aware of the extent of any problems with treatment efficiency. Upon receipt of "greater than" testing results, a facility should consult its laboratory to see if changes in testing procedure need to be made in order to get discreet values from the analysis. For calculation purposes only, the numeric portion of the value must be used to calculate either an arithmetic or geometric mean. 4. Enforcement - Failure to comply with any of the requirements listed above may result in the facility being issued a Notice of Violation or being subject to other appropriate enforcement action. 5. Order of Report Forms-DMR submittals typically include the results of monitoring of the facility's effluent, its influent and its receiving stream. It is requested that for any DMR, the report be bound with the Effluent page(s) (DWQ form MR-1 or MR- 1.1) on top, followed by the Influent page (form MR-2, if influent monitoring is required) and finally the Upstream/Downstream page (form MR-3). 6. Number of Reports -You are required to submit the original and one copy of the report to DWQ. Each copy should be a discreet report for the month, put together in the order described above. 7. Multiple Submittals -School systems and contract operations, please take note of this request. If you submit reports for multiple permits within one mailing, please bind together the submittals (original and one copy) for the various facilities. Please do not segregate the reports into any other type of organization (e.g., binding together all effluent or stream monitoring pages). To do so will cause reports to be taken apart and placed together properly, which slows processing and introduces opportunity for mistakes to be made. If you send many DMRs in one envelope, it is advisable that you send a summary sheet along with the DMRs that lists what reports are contained in the package. 8. Permits for Other Program Areas -Please note that this discussion pertains to submittal of DMRs required' of NPDES permittees (point source discharge pipes to streams). You may have permits for activities in other program areas such as DWQ's non discharge program (wastewater spray irrigation or land application of residuals) or the Division of Environmental Health's public water supply program (drinking water). Please consult those permits for instructions for their submittal. It is not advisable to submit any other reports along with your DMR submittals. 9. Toxicity Reporting -Some permittees will have monitoring requirements for Toxicity within their permits. Please be aware that this parameter has a dual reporting requirement. Results of toxicity testing should be reported on DMR forms, but the toxicity testing results forms must be submitted to the Aquatic Toxicity Unit at the address listed below. Aquatic Toxicology Unit DWQ Environmental Sciences Branch 1621 Mail Service Center Raleigh, NC 27699-1621 f� 10. Corrected or Amended Reports -In the event that you omit or erroneously report data on a DMR, the information should be updated with the submittal of an amended report. To best handle the amended data, the following pL ocedure is recommended: 1. Regenerate or make a copy from your files of the DMR previously submitted to DWQ. 2. Make changes to the individual data points on the form, including updated summary information. 3. Initial and highlight changes to the original submittal. 4. At the top of the reporting page, write very conspicuously: "Amended Report" or "Corrected Report." 5. Provide a short cover page describing the changes to the DMR or note changes in the comment area on the back of the MR-1 form. Use of this procedure will be a great help to DWQ's data entry staff. Without specifically identifying changes on the DMR, each data point must be evaluated between the original and amended reports to ensure the values in our database are correct. Calling attention to just those values that are changed both speeds up our processes and decreases the possibility for errors to be made. 11. Contacts-DWQ deals with a tremendous number of permitted entities that may be experiencing their own changes involving administration and personnel. In dealing with NPDES permit matters, DWQ must deal with only one representative of the permitted facility (someone with authority to see that changes are made at the facility if they are necessary) in order to be effective. You are encouraged to keep DWQ informed of any updates as to the person responsible for the permit, addresses or phone numbers in order to facilitate the best possible communication between our two organizations. This can be done by sending an e-mail to our Unit or by using the back of the MR-1 form under the permittee certification section. Regulations regarding who may be deemed responsible for a permit and who may sign as the "permittee" on the DMR can be found (respectively) in the North Carolina Administrative Code in sections 15A NCAC 2H .106(e) and 15A NCAC 2B .0506 (b)(2).

The Division of Water Quality (DWQ) greatly appreciates the association's continued support of the monitoring and the time and expertise contributed by its members. By this letter the DWQ confirms the waiving of instream monitoring requirements within your individual NPDES permit in exchange for the YPDRBA's monitoring of the watershed as specified within the renewed Memorandum of Agreement (MOA) effective August 12, 2008. The agreement identifies the stations, parameters, and frequency of monitoring required of the association in order to maintain the instream monitoring waivers for your individual permits. Effluent monitoring requirements are not affected. Should your membership in the association be terminated, you must notify DWQ immediately and the instream monitoring requirements in your permit will be reinstated. All other terms and conditions in the original permit remain unchanged and in full effect. These modifications are issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the US Environmental Protection Agency.

This notice is being sent to explain the requirements for your permit renewal application. You are receiving this advance notice because your facility has a permitted flow at or above 1 MGD, or the facility receives industrial [pretreatment] wastewater. If either of these criteria no longer applies, contact the NPDES Unit before submitting a renewal application. Federal (40 CFR 122) and state (15A NCAC 2H.0105(e)) regulations require that permit renewal applications be filed at least 180 days prior to expiration of the current permit. Your renewal application is due to the Division postmarked no later than January 1. 2009. Failure to apply for renewal by the appropriate deadline may result in a civil penalty assessment or other enforcement activity at the discretion of the Director. The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1, 2001. EPA form 2A is attached to this Notice, and must be used for your permit renewal application. The new application requirements mandate additional effluent testing: 1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal application. Collect samples for the PPAs in conjunction with sampling for your current quarterly toxicity test. The new PPA requirements differ from previous versions. Each PPA must include: ➢ Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals that are not normally monitored through your NPDES permit. ➢ Analyses for total phenolic compounds and hardness. ➢ Analyses for all of the volatile organic compounds listed in Part D. ➢ Analyses for all of the acid -extractable compounds listed in Part D. ➢ Analyses for all base -neutral compounds listed in Part D. ➢ Analyses for Total Mercury must be performed using EPA Method 1631. 2. Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with your renewal application. The tests should be conducted quarterly, with samples collected on the same day as your current toxicity test. Call the Aquatic Toxicology Unit at (919) 733-2136 for guidance in conducting the additional tests. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 One 512 North Salisbury Street, Raleigh, North Carolina 27604 NofthCarolina Phone: 919 733-5083, extension 511 / FAX 919 733-0719 / charles.weaver@ncmail.net Naturally An Equal Opportunity/Affirmative Action Employer — 50% Recycled/10% Post Consumer Paper Renewal Notice for Permit NC0020591 Iredell County Page 2 The pollutant and toxicity analyses described above must accompany your permit renewal application, or any major permit modification request. The Division cannot draft your permit without the additional data. Any data submitted cannot be over 4 1/2 years old, and must account for seasonal variation (samples cannot be collected during the same season each year if collected over multiple years). PLEASE NOTE: If your existing permit contains a requirement for annual PPAs, additional PPAs are not required [provided you have conducted at least 3 scans prior to submitting your application]. If any wastewater discharge will occur after the current permit expires, this NPDES permit must be renewed. Discharge of wastewater without a valid permit would violate Federal and North Carolina law. Unpermitted discharges of wastewater could result in assessment of civil penalties of up to $25,000 per day. Use the checklist below to complete your renewal package.

Sullins, Director February 29, 2008 NC DENR MR0 M-Surface Water Protection SUBJECT: Advance Notice of Renewal Application Requirements Permit NCO031836 Fourth Creek WWTP Your NPDES permit for a municipally owned/operated WWTP expires on June 30, 2009. This notice is being sent to explain the requirements for your permit renewal application. You are receiving this advance notice because your facility has a permitted flow at or above 1 MGD, or the facility receives industrial [pretreatment] wastewater. If either of these criteria no longer applies, contact the NPDES Unit before submitting a renewal application. Federal (40 CFR 122) and state (15A NCAC 2H.0105(e)) regulations require that permit renewal applications be filed at least 180 days prior to expiration of the current permit. Your renewal application is due to the Division postmarked no later than January 1. 2009. Failure to apply for renewal by the appropriate deadline may result in a civil penalty assessment or other enforcement activity at the discretion of the Director. The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1, 2001. EPA form 2A is attached to this Notice, and must be used for your permit renewal application. The new application requirements mandate additional effluent testing: 1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal application. Collect samples for the PPAs in conjunction with sampling for your current quarterly toxicity test. The new PPA requirements differ from previous versions. Each PPA must include: Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals that are not normally monitored through your NPDES permit. ➢ Analyses for total phenolic compounds and hardness. ➢ Analyses for all of the volatile organic compounds listed in Part D. ➢ Analyses for all of the acid -extractable compounds listed in Part D. ➢ Analyses for all base -neutral compounds listed in Part D. ➢ Analyses for Total Mercury must be performed using EPA Method 1631. 2. Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with your renewal application. The tests should be conducted quarterly, with samples collected on the same day as your current toxicity test. Call the Aquatic Toxicology Unit at (919) 733-2136 for guidance in conducting the additional tests. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 One 512 North Salisbury Street, Raleigh, North Carolina 27604 NorthCarolina Phone: 919 733-5083, extension 511 / FAX 919 733-0719 / charles.weaver@ncmai1.net Natzmallff An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper Renewal Notice for Permit NC0031836 Iredell County Page 2 The pollutant and toxicity analyses described above must accompany your permit renewal application, or any major permit modification request. The Division cannot draft your permit without the additional data. Any data submitted cannot be over 4 1/2 years old, and must account for seasonal variation (samples cannot be collected during the same season each year if collected over multiple years). PLEASE NOTE: If your existing permit contains a requirement for annual PPAs, additional PPAs are not required [provided you have conducted at least 3 scans prior to submitting your application]. If any wastewater discharge will occur after the current permit expires, this NPDES permit must be renewed. Discharge of wastewater without a valid permit would violate Federal and North Carolina law. Unpermitted discharges of wastewater could result in assessment of civil penalties of up to $25,000 per day. Use the checklist below to complete your renewal package.

Currently we have one of two barscreens in operation. The other barscreen is being used for parts to keep the other one in operation. We have the money allocated to replace this equipment and McGill Associates are in the process of writing a bid spec. for this capitol project. We are looking at installing two new perforated panel, fine screens at the Main Pump Station. We anticipate this project to actually start in early spring of 20083he Fourth Creek WWTP effluent has not been adversely affected due to the inefficiency of the one barscreen that is in operation at this point, I am sending this letter to you as a courtesy and to serve as a status report on this much anticipated capital project.

Per our conversation I understand that our permit requires post aerated effluent, which is our cascade, that we would not be required to operate the blowers in the chlorine contact chambers. You also mentioned that the contact basin should not be aerated; due to the fact air dissipates the chlorine. These blowers are not cost effective due to poor performance and high maintenance costs. These blowers have been out of operation for some time, but we have been compliant with our permit D.O without them. Thanks again for your help and advice.

The 5.9 was recorded on the daily sheet which is part of the DMR for the month. I was somewhat skeptical of this number but I called your office and made contact with Wes Bell. I indicated to Mr. Bell my reason for the call thinking that this would result in a NOV. However, I did tell Wes that all of the data on our process control sheet for the day mentioned showed that the pH ranged from a low of 7.0 to a high of 7.2. Wes Bell said that there would be no violation and to flag this daily sheet. Mr. Bell also indicated to me that we could pick the number that best represents that day for the effluent pH sample.

On Nov. 20, 2006 the general contractor started demolition work in the Dewatering building. At this time the Dewatering building is inoperable. The rental press will be shipped on the 27'h of Nov. and we are expecting to be pressing sludge on the 4th of Dec. We still have the capability to waste sludge and decant the supernatant from the top of the aerobic digester. This project consists of complete removal of the belt thickener, plate and frame press, old piping and tanks that will no longer be needed. The new equipment will consist of a new three belt press; sludge pumps for the press, new RAS and WAS pumps and clarifier weirs. The City anticipates this project to be completed in one year from the start date. With the arrival of the rental press, we will operate this piece of equipment to its full capacity to bring our solids inventory down. I am sending this letter to you as a courtesy and to serve as a status report on this much anticipated capital project.

Center Ave., Suite 301 Mooresville, NC 28115 Re: Requested response to Compliance Inspection Report Dear Mr. Bridgeman: *'&PT. a C P'SbhW*! "Knous"tNA30NAL OFFtIk SEP 0 7 200 WATER QVALITf f _ - As requested in the Compliance Evaluation Inspection Report dated August 24, 2005, this is the written response addressing the deficiencies noted in the Secondary Clarifier, Summary/Self Monitoring Program, and Influent Sampling sections of the report in addition to the concerns about the effluent flow meter and the high water alarm at the influent pump station. Secondary Clarifier As noted in the inspection report, the scum railing and several weir are missing in one clarifier. This clarifier (#2) and the clarifier that is directly to the south (#1) will have their weirs and scum railings replaced as part of a RAS system improvement project that has been engineered by McGill and Associates. The final drawings are currently being reviewed by the State for approval. We hope to have this project out for bids before the end of the year. The debris causing the weir blockages observed in the clarifier closest to the sludge dewatering building have been removed. Summary/Self Monitoring Program As stated in the e-mail messages sent to Mr. Wes Bell on August le and 17t', DMRs for January, March and June of 2005 have been amended and copies forwarded to the Division of Water Quality. These amendments should address and correct the discrepancies for 1/3/05, 3/16/05 and 6/14/05. On July 20, 2004 and April 21, 2005, the samples and crucibles were discarded prior to final calculation and the realization that the dried sample weight had not been analyzed. Upon recommendation of Mr. Chet Whiting we are holding samples in the refrigerator for five (5) days to ensure that this oversight does not cause future violations. The BOD value reported on 2/4/05 for the influent was qualified per State Lab Certification rules. The sample did not use >/= 2.0 mg/I DO and therefore was reported as <2.00 mg/l. All quality control measures were met. :Z;T it* 44 x nro, ty rj k'l i, 1711 rw bil-,--- .,v VI4V It il�T,� -Tk�slf: I • Page 2 September 2, 2005 The operators collecting the samples have been informed on the proper way to fill out the chain of custody forms and the importance of recording data accurately. The operators have also been informed to read the sampler temperatures immediately after opening the composite sampler to minimize the chance of any raise in temperature of the sampler or the sample. The addition of ice packs in the composite refrigerator will be initiated on warm days to help maintain the required 1.0 ° C — 4.4 ° C. Influent Sampling The tubing on the influent composite sampler has been changed and will be be cleaned no less than once per week. Effluent Flow Meter Concerns Upon review of the calibration records that cover the past nine years, this is the first problem with the calibration of this meter on record. Due to the fact that parts for this flow measurement system are no longer available, our contracted company, Carolina Technical Services (CTS), has recommended replacement. The purchase and installation of a new effluent flow meter will be requested on the next capital budget. Influent Pump Station Concerns As was pointed out in the report, in order to fully conform to minimum design requirements in 15A NCAC 02H.0219(h), an audible high water alarm should be added to the pump station and the visual and audible alarms should placed so that they can be seen and heard in the most effective area. CTS is quoting the installation of a strobe light and hom to be added to the high water alarm system. It will be placed in a highly recognizable location. If there are any further questions or concerns, please call me at 704-878-3438. Sincerely, ;a A�L 402'�- Todd Aaron Norman ORC, Fourth Creek WWTP Michael F. Easley, ilvernor / William G.

SUMMARY Self -monitoring reports were reviewed for the period May 2004 through June 2005, inclusive. Monthly average effluent ammonia violations were reported for May 04 and April 05. Weekly average effluent fecal coliform and chromium violations were reported during September 04. Monthly and weekly average effluent BOD violations were reported for April 05. The facility did not achieve 85 % TSR removal efficiency during March 05 and April 05. Note: The Division has issued a NOV and/or NOV/civil penalty assessment for the above - noted limit violations. Several monitoring violations were noted during the review period. No influent TSR values were reported on 7/20/04, 1/3/05, and 4/21/05. In addition, no effluent TSR value was reported on 3/16/05. No influent and effluent BOD values were reported on 6/14/05. This office questions the accuracy of the < 2 mg/1 influent BOD value reported on 2/4/05. Mr. Chet Whiting (Division's Laboratory Certification Unit) has been notified of the above -noted discrepancies. The facility staff must ensure all "less than" values are appropriately calculated when determining the monthly average values. In addition, numerous transcription errors were noted in the June 05 self -monitoring program (chain -of -custodies, data transcriptions, etc.). Discrepancies in the self -monitoring program were noted in the previous inspection report dated 2/24/04. On several occasions, the composite sampler temperatures were outside the temperature range of 1.0°C - 4.4°C. Facility staff must ensure all composite samples are appropriately preserved during the composite sampling periods. RISK MANAGEMENT PROGRAM: 1.

The surge occurred when power was lost to the plant due to the fire at L. Gordon Iron and Metal Co. located at I — 77 exit 49B. The power was disabled by the City Light Department for safety concerns. The power was interrupted at Fourth Creek WWTP at that time and the back up generator came into operation. At some time between when the generator came online and main utility power restored was when the surge occurred. The surge was on one leg of the three electrical phases feeding the MCCs. We called Russelectric, the manufacturers and servicers of the generator switch gear, and they sent a technician to see if there was a problem with the synchronization from back up power to main utility. He advised us that there were no noticeable problems with the switch gear or its operation. He suggested that there was a possibility that the surge could have come from the utility during the fire if two phases crossed or from the MCCs themselves - We had parts ordered to repair the MCCs and they were placed back into service at approximately 8:00 pm Friday. Both aeration basins were inoperable for approximately 28 hours. Should you require more information, or if further action is required, please contact me at 704-878- 3438.

OFFICE MAY 1 6 2005 WATER X' SECTION Re: Non -Compliant effluent ammonia nitrogen, effluent BOD, and effluent TSS percent removal for April 2005 Fourth Creek Wastewater Treatment Plant NPDES Permit No. NCO031836 Dear Mr. Lesley: Upon completion of the monthly DMR, it was noted that results from the on -site lab showed that the monthly averages for effluent ammonia nitrogen and effluent BOD for April 2005 were non -compliant. The monthly average for the effluent ammonia nitrogen was 14.4 mg/L with a limit of 12.0 mg/L and the monthly average for the effluent BOD was 18.0 mg/L with a limit of 17 mg/L. The condition that contributed to the situation was the motor control center (MCC) replacement project that was underway during the month. The lack of proper aeration and mixing in our two aeration basins during the replacement period had an adverse impact on the effluent ammonia nitrogen and the effluent BOD. The MCC project is now complete and we have seen an improvement in both of these parameters due to the fact that we are now able to incorporate more oxygen into the basins. We have been aggressively wasting the excess solids that have accumulated in the aeration basins since the start of the project. We are utilizing our normal wasting pumps and a portable diesel pump to waste directly from the aeration basins to the digester. Since we began the increased wasting we have seen a sharp drop in effluent ammonia nitrogen and the effluent BOD levels due to a decreased amount of aeration solids and increased aeration efficiency. We fully expect to see further improvement in the ammonia nitrogen and effluent BOD levels with the present operational procedure. According to the data received from our on -site lab, our monthly total suspended solids limit was compliant with a monthly average of 25.7 mg/L (limit 30.0 mg/L). However the total suspended solids percent reduction was not compliant with the 85% monthly removal requirement. The Fourth Creek WWTP TSS reduction for the month of April was 78%. Beginning in February 2005, a sharp drop in influent suspended solids was noticed. This was verified by looking at the monthly averages of previous months. The influent TSS drop can be seen as follows: November 2004 — 183 mg/L, December 2004 — 228 mg/L, January 2005 — 260 mg/L, February 2005 —111 mg/L, March 2005 — 90 mg/L , April 2005 — 117 mg/L. Toward the end of April, an upward trend began to be seen with the daily influent TSS.

The surge occurred when power was lost to the plant due to the fire at L. Gordon Iron and Metal Co. located at I — 77 exit 49B. The power was disabled by the City Light Department for safety concerns. The power was interrupted at Fourth Creek WWTP at that time and the back up generator came into operation. At some time between when the generator came online and main utility power restored was when the surge occurred. The surge was on one leg of the three electrical phases feeding the MCCs. We called Russelectric, the manufacturers and servicers of the generator switch gear, and they sent a technician to see if there was a problem with the synchronization from back up power to main utility. He advised us that there were no noticeable problems with the switch gear or its operation. He suggested that there was a possibility that the surge could have come from the utility during the fire if two phases crossed or from the MCCs themselves. We had parts ordered to repair the MCCs and they were placed back into service at approximately 8:00 pm Friday. Both aeration basins were inoperable for approximately 28 hours.

The average for the week was 26.8 mg/L BOD. Our weekly limit for this time of the year (April 1 — October 31) is 25.5 mg/L BOD. The condition that contributed to the situation was the MCC replacement project that was underway during the month. The lack of proper aeration and mixing in our two aeration basins during the replacement period had an adverse impact on our effluent BOD. The MCC project is now complete and we expect to see an improvement in the effluent BOD due to the fact that we are now able to incorporate more oxygen into the basins. We are also aggressively wasting the excess solids that have accumulated in the aeration basins since the start of the project. We are now able to move more solids into the clarifiers for wasting purposes. Should you require more information, or if further action is required, please contact me at 878-3438.

The Fourth Creek WWTP TSS reduction for the month of March was 70%. Beginning in February 2005, a sharp drop in influent suspended solids was noticed. This was verified by looking at the monthly averages of previous months. The influent TSS drop can be seen as follows: November 2004 —183 mg/L, December 2004 — 228 mg/L, January 2005 — 260 mg/L, February 2005 —111 mg/L, March 2005 — 90 mg/L. The second condition that contributed to the situation was the MCC replacement project that was underway during the month. The lack of proper aeration and mixing in our two aeration basins during the replacement period also had an adverse impact on our solids and the reduction rate. The MCC project is now complete and a gradual improvement of the effluent TSS is beginning to be seen. As for the influent solids, the cause is still unknown as to why the incoming TSS still continues to be lower than normal; however, we are currently investigating any possible causes of the drop in suspended solids Should you require more information, or if further action is required, please contact me at 878-3438 Sincerely, Todd Norman Senior Operator, Fourth Creek WWTP I.J.

Please review the draft very carefully to ensure thorough understanding of the conditions and requirements it contains. The draft permit contains the following significant changes from your current permit: The daily maximum total residual chlorine (TRC) limit has been added to the permit. See the attached total residual chlorine policy memo for details. The facility is allowed 18 months from the effective date of the permit to comply with the total residual chlorine limit. This time period is allowed in order for the facility to budget and design/construct the dechlorination and /or alternative disinfection systems. • A weekly average limit for ammonia nitrogen has been added to the permit. The Division of Water Quality was required to implement weekly average NH3-N (ammonia) limits for municipal facilities, as required by the Code of Federal Regulations. This implementation policy was adopted October 15, 2002. The weekly average value is three times the monthly average value (this multiplier was established based on a review of treatment capability at various plants). Weekly average values are capped at 35 mg/L. This permit includes both monthly average and weekly average limits for NH3- N. • An annual pollutant scan has been added to your permit. By performing this scan concurrent with your toxicity test (at different times of the year), you will be able to collect sufficient data for the new renewal application required by the Environmental Protection Agency (EPA). • Limits for cadmium, chromium and lead have been eliminated from the permit and monitoring will be required quarterly within the City's pretreatment program.

Secretary North Carolina Department of Environment and Natural Resources June 19, 2003 SUBJECT: Total Residual Chlorine Policy for NPDES permits Alan W. Klimek, P.E., Director Division of Water Quality Every three years the State is required by the Clean Water Act to review its surface water quality standards and classifications, determine if changes are needed and to make any necessary changes. This review process is referred to as the "triennial review." Public hearings were held to solicit comments for the 2000-2003 Triennial Review of surface water quality standards during the summer of 2002. The Hearing Officer's recommendations were presented before the state's Environmental Management Commission on October 10, 2002. The Hearing Officer's recommended changes included modifications to the existing standards for Arsenic, Cyanide, Methylene Blue Active Substances (MBAS) and Total Residual Chlorine CTRC). The Hearing Officer also recommended the addition of a standard for Methyl Tert-Butyl Ether (MTBE). All of the Hearing Officer's proposed changes were adopted with the exception of MTBE. The changes took effect on April 1, 2003. This memo documents the changes to the NPDES permitting policy for TRC limits. Total Residual Chlorine (TRC) Previously, TRC had an Action Level Standard, except in designated Trout waters. The Triennial Review changes modified the TRC Action Level Standard to an Aquatic Life Standard of 17 µg/L- The Aquatic Life Standard will remain for designated Trout waters. Aquatic Life Standard — 17 µg/L (freshwater only) Trout Waters —17 jig/ L Revised TRC Policy ➢ TRC limits will be assigned to permit renewals and all new permits issued after April 1, 2003. ➢ Facilities that do not use chlorine will not receive a TRC limit; however, the presence of a chlorine back-up system to augment UV or other disinfection requires a TRC limit. ➢ Facilities discharging to streams with a 7Q10 <0.05 cfs (zero -flow streams) will receive a limit of 17 µg/L. ➢ Limits will be capped at 28 µg/L to protect against acute impacts. It is likely that many facilities will need to add dechlorination (or use another means of disinfection) to comply with the new TRC standard. Therefore, a compliance schedule of 18 months from the effective date of the permit may be added to any TRC limit added during the current permit renewal. This time period is allowed in order for the facility to budget and design/construct the dechlorination and/or alternative disinfection system(s). The NPDES Unit has promulgated minimum design criteria in order to expedite permitting of dechlorination equipment. cc: Coleen Sullins Regional Office Supervisors (Dechlorination guidance attached) Shannon Langley 1 f� JUL 2 4 ?nnQ PUBLIC WATER SUPPLY SECT 110h DENR/DWQ FACT SHEET FOR NPDES PERMIT DEVELOPMENT NPDES No. NCO020591 Facility Information Facility Name: Fourth Creek WWTP, City of Statesville Permitted Flow: 4.0 — 6.0 MGD County: Iredell Facility Class: IV Regional Office: Mooresville Facility/Permit Status: (i.e. New, Modification, Existing or Renewal) Existing USGS Topo Quad: D15SE Stream Characteristics Receiving Stream: Fourth Creek Stream Classification: C Winter 7Q10 (cfs): 11.3 Subbasin: 03-07-06 30Q2 (cfs): 16.0 Drainage Area (mi2): 46.5 Average Flow (cfs): 46.5 Summer 7Q10 (cfs) 7.5 IWC (%): 36/55 303d Listed Yes (fecal) TMDL: Approved by EPA SUMMARY This facility is a major municipal treatment plant operating in Iredell County that serves 25,000 people in Statesville.

Existing Limit: 001: Chronic P/F @ 36% (4MGD)/55% (6 MGD) Recommended Limit: 001: Chronic P/F @ 36% (4MGD)/55% (6 MGD) Monitoring Schedule: January, April, July, and October The facility has been generally passing its WET tests. Failures occurred only on two occasions (January 2001, and January 2002). COMPLIANCE SUMMARY: DMRs have been reviewed for the period January 2001 through April 2004. Facility has a good compliance record. During the review period, the following NOVs (notices of violation) have been issued: 10/14/02 — DO; 4/8/02 — toxicity; 04/02/01 — toxicity. PPOF,F" . A compliance evaluation inspection conducted on February 24, 2004 did not identify any major problems. Some minor flow -meter issues were noted. INSTREAM MONITORING: Instream monitoring is required for temperature and dissolved oxygen. Monitoring is conditionally waived based on the participation in the Yadkin -Pee Dee Monitoring Coalition. An analysis of DO, temperature and conductivity data showed that the facility has some negative influence on conductivity of the stream water (table is attached). Data does not indicate that the facility has a noticeable impact on stream DO and temperature. Fourth Creek is impaired due to high level of fecal coliforms and is also biologically impaired. TMDL has been developed for fecal coliforms, non -source pollution is believed to be the major cause of impairment. Statesville is limited at the end -of -pipe based on the water quality standard for fecal Coliform. PROPOSED CHANGES: • Monitoring Frequencies: Monitoring for Cd, Cr, and Pb has been eliminated based on the Reasonable Potential Analysis. Limits: Based on the Reasonable Potential Analysis, the limits for cadmium and lead have been removed. The daily maximum total residual chlorine limit and weekly average NH,-N limit have been added to the permit. Priority pollutant monitoring on an annual basis has been added to fulfill the permit application requirement in the future. Existing permit limits and recommended limits/monitoring are summarized in the table below: Parameter Existing Limit Existing Monitoring Proposed Limit Proposed Monitoring Cadmium 15.0 Weekly None Quarterly (through LTMP) Lead 33.8 Weekly None Quarterly (through LTMP) Chromium 1 90.4 1 Weekly None I Quarterly (through LTMP) The existing monitoring frequency for silver, zinc, and copper remains unchanged. Due to the facility's toxicity record, limits for these action level standards will not be implemented, but monitoring will remain. All other parameters evaluated showed no reasonable potential to exceed the instream water quality limits or federal criteria. PROPOSED SCHEDULE FOR PERMIT ISSUANCE: Draft Permit to Public Notice: May 26, 2004 (est.) Permit Scheduled to Issue: July 19, 2004 (est.)

TOTAL AMOUNT DUE Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken into account the Findings of Fact and Conclusions of Law and the factors set forth at G.S. 143B- 282.1(b), which are: (1) The degree and extent of harm to the natural resources of the State, to the public health, or to private property resulting from the violations; (2) The duration and gravity of the violations; (3) The effect on ground or surface water quantity or quality or on air quality; (4) The cost of rectifying the damage; (5) The amount of money saved by noncompliance; (6) Whether the violations were committed willfully or intentionally; (7) The prior record of the violator in complying or failing to comply with programs over which the Environmental Management Commission has regulatory authority; and (8) The cost to the State of the enforcement procedures. Within thirty days of receipt of this notice, you must do one of the following: 1.

Submit a written request for remission including a detailed justification for such request: Please be aware that a request for remission is limited to consideration of the five factors listed below as they may relate to the reasonableness of the amount of the penalty assessed. Requesting remission is not the proper procedure for contesting whether the violation(s) occurred or the accuracy of any of the factual statements contained in the civil penalty assessment document. Because a remission request forecloses the option of an administrative hearing, such a request must be accompanied by a waiver of your right to an administrative hearing and a stipulation that no factual or legal issues are in dispute. Please prepare a detailed statement that establishes why you believe the civil penalty should be remitted, and submit it to the Division of Water Quality at the address listed below. In determining whether a remission request will be approved, the following factors shall be considered: (1) whether one or more of the civil penalty assessment factors in G.S. 14313- 282.1(b) were wrongfully applied to the detriment of the petitioner; (2) whether the violator promptly abated continuing environmental damage resulting from the violation; (3) whether the violation was inadvertent or a result of an accident; (4) whether the violator had been assessed civil penalties for any previous violations; or (5) whether payment of the civil penalty will prevent payment for the remaining necessary remedial actions. Please note that all information presented in support of your request for remission must be submitted in writing. The Director of the Division of Water Quality will review your evidence and inform you of his decision in the matter of your remission request. The response will provide details regarding case status, directions for payment, and provision for further appeal of the penalty to the Environmental Management Commission's Committee on Civil Penalty Remissions (Committee).

The reason for the non- compliance is failure of the existing aerators to perform on a consistent basis. The motor control centers (MCCs) for both of our aeration basins have developed electrical problems due to excessive age. Through the efforts of the plant maintenance mechanics, all of the aeration basin aerators are temporarily operational. Since it is impossible to permanently repair the current MCCs or return them to 100% operational ability, the City will be replacing these units with new ones. Bid opening for this major project is scheduled for June 24, 2004 and the project is slated for completion within the next twelve months.

This advance notice is being sent to explain the new requirements for your permit renewal application. You are receiving this advance notice because your facility has a permitted flow at or above 1 MGD, or your WWTP has a pretreatment program. If either of these criteria no longer apply to your facility, contact the, NPDES Unit before submitting a renewal application. Federal (40 CFR 122) and state (15A NCAC 2H.0105(e)) regulations require that permit renewal applications be filed at least 180 days prior to expiration of the current permit. Your renewal application is due to the Division no later than February 2, 2004. Failure to apply for renewal by the appropriate deadline may result in a civil penalty assessment or other enforcement activity at the discretion of the Director. The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1, 2001. EPA forms 1 and 2A are attached to this Notice, and must be used for your permit renewal application. The new application requirements mandate additional effluent testing: 1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal application. Collect samples for the PPAs in conjunction with sampling for your current quarterly toxicity test. The new PPA requirements differ from previous versions. Each PPA must include: ➢ Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals that are not normally monitored through your NPDES permit. ➢ Analyses for total phenolic compounds and hardness. ➢ Analyses for all of the volatile organic compounds listed in Part D. ➢ Analyses for all of the acid -extractable compounds listed in Part D. ➢ Analyses for all base -neutral compounds listed in Part D. 2. Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with your renewal application. The tests should be conducted quarterly, with samples collected on the same day as your current toxicity test. Call the Aquatic Toxicology Unit at (919) 733-2136 for guidance in conducting the additional tests. These additional analyses must accompany your permit renewal application, or any request for a major permit modification. The Division cannot draft your permit without the additional data. Any data submitted cannot be over 4 '/z years old, and must account for seasonal variation (samples cannot be collected during the same season each year if collected over multiple years). 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 919 733-5083, extension 511 (fax) 919 733-0719 VISIT USONTHEINTERNET@http://h2o.enr.state.nc.us/NPDES charles.weaver@ncmail.net Renewal Notice for Permit NC0031836 Iredell County Page 2 If your permit already contains a requirement for an annual effluent pollutant scan, additional scans are not required [provided you have conducted at least 3 scans prior to submitting your application]. If any wastewater discharge will occur after the current permit expires, this NPDES permit must be renewed.

Box 1111 Statesville, NC 28677 Number: 181 Maintenance October 10, 2003 Chet Whiting Ms. Carol Rogers The above named laboratory was inspected to verify compliance with 15A NCAC 2H .0800 for the analysis of environmental samples. II. OVERVIEW: The laboratory was neat and well organized. Laboratory personnel provided the inspector(s) with all materials, and information requested for examination. The Laboratory continues to do an excellent job overall. III. DEFICIENCIES, REQUIREMENTS, COMMENTS, AND RECOMMENDATIONS: GENERAL LABORAOTORY: A). COMMENT: Issues concerning low-level duplicate acceptance criteria in general were discussed. RECOMMENDATION: It was recommended that the laboratory establish criteria for fecal counts of less the 20 FCU/plate, and retain the use of RPD to evaluate samples greater than 20 FCU/plate. An example of ± 5 colonies for plates with less than 20 colonies was discussed. As with most analyses the use of RPD and calculated limits is problematic at lower concentrations. Please note that this may apply to other acceptance criteria, low-level suspended solids samples in particular. Possible evaluation criteria for low level TSS were discussed at the inspection. If you have any questions do not hesitate to contact this office. CYANIDE: B. COMMENT: The cyanide LCS (Laboratory Control Standards) are not distilled as samples. REQUIREMENT: This program considers the LCS a method quality control sample. The purpose of the LCS is to evaluate the efficiency and performance of the entire procedure. The LCS must therefore be treated, in every aspect, as a sample. The LCS is sometimes referred to as the LFB (Laboratory Fortified Blank). Standard Methods 20`h Edition 1020 B states in part: "Process the Page 2 Statesville Fourth Creek LFB through all of the sample preparation and analysis steps". The general requirement for analysis of a second source standard is 15A NCAC 2H .0805 (a) (7) (B) which states in part: "analyze one known standard in addition to calibration standards each day samples are analyzed to document accuracy". The laboratory may purchase a known LCS, or prepare a LCS using a standard from a different vendor, or a different lot number from the same vendor. CHEMICAL OXYGEN DEMAND: C. COMMENT: The lowest standard (low level) is 5mg/L. Data indicates that this concentration is on the edge of the viability. Standard checks at this level are obtaining 25% recovery with some inconsistency. RECOMMENDATION: It is recommended that the laboratory raise the lower standard to 10mg/L. This change should not affect any reporting issues. D. COMMENT: The accuracy of the conductivity meter auto cell constant function is not verified annually. REQUIREMENT: Verify the accuracy of the conductivity meter auto cell constant function annually, and document. NOTE: Verification of the cell constant and temperature compensator functions may be accomplished as follows: analyze a sample, slightly heat, or cool the sample, then reanalyze the sample. If the meter is functioning properly there should be little or no difference between the results. OIL AND GREASE METHOD 1664 (SPE): E. COMMENT: Sample drying cycle is not repeated until a constant weight is obtained of less than 4%, or is > 0.5 mg. The drying cycle is not sufficient. REQUIREMENT: If the drying cycle is not sufficient adjust the procedure until the weight change is less than 4% or < 0.5 mg. This procedure must be performed for each sample.

Tracy Subject: Fourth Creek TMDL Stressor Study, June and July 2003 (Iredell and Rowan counties, Yadkin River Basin, Subbasin 06) As part of the development of a Total Maximum Daily Load Stressor Study for Fourth Creek, the benthic macroinvertebrate and fish communities at several sites on Fourth Creek were evaluated during June and July 2003. A 9.5 mile reach of the stream from 1.5 miles upstream of SR 2308 (Iredell County) to SR 1003 (Rowan County) is on the 2002 303 (d) list of biologically impaired streams because of sediment and turbidity (NCDENR 2003). This memorandum summarizes the results from this monitoring. WATERSHED DESCRIPTION The watershed of Fourth Creek lies wholly within the Northern Inner Piedmont and the Southern Inner Piedmont (Griffith et al. 2002). The creek is a large (83 square mile) Class C tributary to Third Creek. The headwaters of Fourth Creek are in an area of agricultural land use near the Town of Stony Point (Figure 1). The stream flows east -southeastward across Iredell County through the City of Statesville (2003 population = 23,500 est.) and across the intensively developed Interstate 40 — NC 115 corridor where it receives urban runoff from several small tributaries. The city encompasses an area of 21.3 square miles of which a majority of the city limits are within the Fourth Creek drainage. The remaining part of the city's watershed lies within the Third Creek drainage. Downstream of the city, Fourth Creek flows northeasterly through rural northwestern Rowan County until it joins Third Creek near the Town of Coolemee. There are two permitted wastewater treatment plant (WWTP) dischargers in the watershed and both discharge to Fourth Creek -- the City of Statesville's Fourth Creek (off SR 2313) and three-quarters mile downstream the Southern States Cooperative's (off SR 2312) WWTPs. The two facilities have a combined discharge of 4.1 MGD. Under 7Q10 conditions the discharge from the city's WWTP may constitute 55% of the stream flow. In 2002 during the prolonged drought, monthly WWTP discharges ranged from 2.4 - 3.2 MGD (self monitoring data submitted to DWQ). However creek flows during the drought were as low as 1 cfs (0.65 MGD) (see Section on Flow). During periods of high rainfall, discharge from the Statesville's WWTP may exceed 4.0 MGD due to infiltration problems in the collection system. There have been few recorded effluent toxicity problems with the facility and no test failures since February 2002 (NCDENR 2002). HISTORICAL DATA Previous studies have focused on the biological (benthic macroinvertebrate and fish communities), ambient chemistry, and effluent toxicity monitoring of the Fourth Creek watershed: Impacts from Statesville's WWTP 1. Benthic macroinvertebrates above (SR 2322) and below (SR 2321) Statesville's WWTP were sampled during September 1987 (Biological Assessment Unit Memorandum B-870921). Both sites were rated Good -Fair and there were few spatial differences. Extensive deposits of sand and silt also were noted at both sites. (Note: since this study was completed the WWTP discharge point was moved and the Plant increased its permitted discharge flow.] 2. Benthic macroinvertebrates were sampled in September 1989 above (SR 2316) and below (SR 2308) the new WWTP discharge (Biological Assessment Unit Memorandum B-890930). Ephemeroptera+Plecoptera+Trichoptera taxa richness (EPT S) was similar at both sites, but there was a between -site difference in the community structure which indicated a shift towards a more tolerant community. The Biotic Index (BI) was greater downstream than upstream. Ephemeroptera and Plecoptera were dominant upstream, while hydropsychids and oligochaetes were dominant downstream. This shift indicated a large input of suspended particulate organic matter. Some other groups (notably riffle beetles) also declined between these two stations. The upstream site was rated Good -Fair, while the downstream site was rated Fair. A whole effluent toxicity test of the treated effluent was also conducted in 1989. The study predicted that the discharge would exhibit acute and chronic toxicity at 7Q10 flow conditions. Elevated concentrations of metals (copper, nickel, and mercury) and total suspended solids were documented downstream of the discharge (Aquatic Toxicity Group Report T-900202). 3. As part of a Fourth Creek 303 (d) study, benthic macroinvertebrates were again sampled above (SR 2316) and below (SR 2308) Statesville's WWTP during September 2001 and July 2002. Results were very similar to those recorded in 1989: similar EPT S at both sites but a BI greater downstream than upstream. Because of the lower EPT S in 2001 compared to 1989, both sites were rated Fair. Resampling of the SR 2316 site in July 2002 produced a Good -Fair rating because of a one taxa increase in EPT S (13 in 2001 vs. 14 in 2002). The ratings for this segment of the creek are expected to fluctuate between Good -Fair and Fair. Basinwide Monitoring 1. In 1996 and 2001 as part of the Yadkin River basinwide monitoring program, benthic macroinvertebrates were collected from a site (SR 1003 in Rowan County) in the lower portion of the watershed (NCDEHNR 1997 and NCDENR 2002). This reach of the stream is somewhat atypical in having boulder -rubble riffles; this substrate composition does not occur further downstream at SR 1985. This site showed some recovery from the effects of the point and nonpoint source runoff from the Statesville area. The site was rated Good in August 1996 and September 2001, but received a Good -Fair rating in July 2001. EPT S and BI values were fairly consistent over these three collections which indicated no significant changes in water quality. 2. Fish community collections at SR 1985 were rated Poor in 1996 and 2001. The reasons for the differences between the fish and macroinvertebrate ratings were unclear, although it was likely that the fish are responding more to the very poor instream habitats, sediment load, and water quality found throughout the watershed than are the benthic macroinvertebrates. Ambient Monitoring As part of DWQ's statewide Ambient Water Chemistry Monitoring Program, samples are collected monthly from Fourth Creek at SR 2308. Samples are also collected monthly at this site and at SR 2316 as part of the Yadkin Pee Dee River Basin Association Monitoring Program (NCDENR 2002). During the period 1997 - 2001 the SR 2308 site showed elevated conductivity (median = 132 pmhos/cm). Conductivity has been increasing over time from a median of about 100 ,umhos/cm during 1995 - 1997 to about 150 /jmhos/cm in later years. Part of this increase may reflect frequent droughts in recent years with less dilution of upstream discharges. Thirteen percent of the samples exceeded the turbidity standard and fecal coliform bacteria counts (geometric mean = 504 colonies/ml) were greater than at all other sites in the entire Yadkin River basin except for one (Salem Creek in Forsyth County). Almost one-half of the bacterial counts were greater than the standard of 400 colonies/ml. Between 1995 and 2002, no dissolved oxygen concentrations were less than 5.5 mg/L and most concentrations were greater than 6.0 mg/L. Total phosphorus concentrations increased from 1995 to 2000, but have since declined. SAMPLE LOCATIONS In June 2003 benthic macroinvertebrates were sampled at seven sites (Figure 2) and the fish communities also were sampled in July 2003 at Site Nos. 1 — 4: 1. Fourth Creek Site No. 1 at SR 1930, north of Interstate 40 and above Statesville. 2. Fourth Creek Site No. 2 at SR 2320, east of Statesville. This site is upstream of the city's WWTP, but still receives urban runoff. The SR 2320 site replaced the historically sampled site above the WWTP (SR 2316) because it was too deep to sample in June 2003. The new site is about three miles upstream of the SR 2316 site. 3. Fourth Creek Site No. 3 at SR 2308, southeast of Statesville and approximately three miles below the city's WWTP. This site had been sampled in June 1989 and September 2001. 4. Fourth Creek Site No. 4 at SR 1985 in Rowan County, east of Statesville, approximately 15 miles below the city's WWTP, and one mile above its confluence with Third Creek. This site is intended to measure any potential recovery from the WWTP discharges and urban runoff from Statesville. 5. Morrison Creek at SR 1907, above Statesville. 6. UT Fourth Creek at SR 2322. Most small streams draining the urbanized area were too small to sample. The largest of the tributaries (UT Fourth Creek at SR 2322) drained a highly urbanized section of Statesville. 7. Rocky Creek at SR 1854. Rocky Creek was the nearest stream that did not show severe habitat problems and which was suitable as a benthic macroinvertebrate reference site. Other nearby streams (e.g., Patterson and Olin Creeks) showed symptoms of extensive habitat degradation, including heavy sediment loads, severe bank erosion, and poor riparian buffer zones. Rocky Creek was selected as a control stream based on its Excellent ratings in 1990 (Biological Assessment Unit Memorandum B-901210) and field reconnaissance in June 2003. • Benthos Stations v {� ■ Fish, Benthos Stations ♦ Fish, Benthos, Ambient Station A® Wastewater Treatment Plant N 0 1 2 MR., Delve Rowan Co.

These methods included Standard Qualitative (= Full Scale) and EPT samples (NCDENR 2001a): 1. Standard Qualitative. This method includes 10 composite samples: two kick -net samples, three bank sweeps, two rock or log washes, one sand sample, one leafpack sample, and visual collections from large rocks and logs. The purpose of these collections is to inventory the aquatic fauna and produce an indication of relative abundance for each taxon. Organisms were classified as Rare (1 - 2 specimens), Common (3 - 9 specimens), or Abundant (>_ 10 specimens). Several data analysis summaries (metrics) can be produced from standard qualitative samples to detect water quality problems. These metrics are based on the idea that unstressed streams and rivers have many invertebrate taxa and are dominated by intolerant species. Conversely, polluted streams have fewer numbers of invertebrate taxa and are dominated by tolerant species. The diversity of the invertebrate fauna is evaluated using taxa richness counts; the tolerance of the stream community is evaluated using a biotic index. EPT taxa richness (EPT S) is also used to assign water quality ratings (bioclassifications). "EPT" is an abbreviation for Ephemeroptera+Plecoptera+Trichoptera, insect groups that are generally intolerant of many kinds of pollution. Higher EPT S values usually indicate better water quality. Water quality ratings also are based on the relative tolerance of the macroinvertebrate community as summarized by the North Carolina Biotic Index (NCBI). Tolerance values for individual species and the final BI values range between 0 and 10, with higher numbers indicating more tolerant species or more polluted conditions. Water quality ratings assigned with the BI were combined with EPT S ratings to produce a final bioclassification using Piedmont stream criteria. EPT abundance (EPT N) and Total S calculations also are used to help examine between -site differences in water quality. When the EPT S rating and the BI differ by one bioclassification, the EPT N value was used to produce the final site rating. 2. EPT samples. EPT methods use only four samples: 1 kick, 1 sweep, I leafpack, and visuals. Only the EPT are collected. The ratings are based solely on EPT S, but have lower expectations than a Full Scale method. The 10-sample EPT S, however, can be estimated from the 4-sample value by applying a correction factor of 1.15. For fish community assessments, a distance of 600 ft. at each site was sampled following all methods (including physical -chemical and habitat assessments) in the existing North Carolina Index of Biotic Integrity (NCIBI) protocols (NCDENR 2001 b). The fish within the delineated stretch were collected using two backpack electrofishing units with each unit accompanied by one person netting fish. After collection, all readily identifiable fish were examined for sores, lesions, fin damage, and skeletal anomalies, measured (total length to the nearest 1 mm), and then released. Those fish that were not readily identifiable in the field were preserved in 10% formalin and returned to the laboratory for identification, examination, and total length measurement. These fish were then deposited as voucher specimens with the North Carolina State Museum of Natural Science in Raleigh. All young -of -year were excluded from the data analyses. The NCIBI method was developed for assessing a stream's biological integrity by examining the structure and health of its fish community. The scores derived from this index are a measure of the ecological health of the waterbody and may not directly correlate to water quality. For example, a stream with excellent water quality, but with poor or fair fish habitat, would not be rated excellent with this index. However, in many instances, a stream which rated excellent on the NCIBI should be expected to have excellent water quality. The assessment of biological integrity using NCIBI is provided by the cumulative assessment of 12 parameters or metrics. The values provided by the metrics are converted into scores on a 1, 3, or 5 scale. A score of 5 represents conditions which would be expected for undisturbed reference streams in the specific river basin or ecoregion, while a score of 1 indicates that the conditions deviate greatly from those expected in undisturbed streams of the region. Each metric is designed to 5 contribute unique information to the overall assessment. The scores for all metrics are then summed to obtain the overall NCIBI score. Finally, the score (an even number between 12 and 60) is then used to determine the ecological integrity class of the stream from which the sample was collected. An assessment technique has been developed by the Biological Assessment Unit to better evaluate a stream's physical habitat (NCDENR 2001a). The habitat score, which ranges between 1 and 100, is based on eight characteristics including channel modification, instream habitat, bottom substrate, pool variety, bank stability, light penetration, and riparian zone width. Higher numbers suggest better habitat quality, but criteria have not been developed to assign ratings. At each site surface water temperature, dissolved oxygen, and conductivity (specific conductance) measurements were collected using a calibrated YSI 85 Oxygen, Conductivity, Salinity, and Temperature meter. Surface pH measurements were also made at each site with a calibrated Fisher Scientific Accumet Portable AP 61 pH meter. RESULTS AND DISCUSSION Flows The flows in Fourth Creek (as based upon the USGS gauge on Second Creek at US 70 near the Town of Barber in Rowan County), have varied substantially during the past 360 days (Figure 3). In 2002 the flows were consistently less than the median flows and were as low as 1 cfs. This was in contrast to 2003 where the flows since late February have been consistently greater than the median flows and have on several occasions been greater than 1,000 cfs (e.g., in early April 2003 the flows were as great as 4,000 cfs). The extremely high flows during much of 2003 have caused considerable sloughing of banks, recent overbank deposits of sand and sediment, and the addition of very large obstructions of woody debris into the channel (see Habitat Section). Water Chemistry During benthic and fish community sampling, the specific conductance (conductivity) generally increased in a downstream manner from Site No. 1 to Site No. 4 (Tables 1 — 3) and reflected the contributions from the urbanized watershed, the wastewater treatment plants, and differences in landuse practices. Conductivity was also elevated at UT Fourth Creek (134 pmhos/cm) and reflected the stream's urban watershed. In contrast to the sites within the Fourth Creek watershed, Rocky Creek had the lowest conductivity (36 pmhos/cm) of any site in this study in spite of recent heavy rainfall. Historically, Site No. 3 has usually had a greater conductivity than that of the other sites. An increase (relative to Site No. 2) has always been observed, but the increase was small when instream dilution was high. For example, in June 2003 (during high flow conditions), the difference in conductivity between Site Nos. 2 and 3 was only 13 pmhos/cm. Under low flow conditions in September 2001, the difference was 50 pmhos/cm. During fish community sampling dissolved oxygen saturation was greater than 80 percent; pH was unremarkable (i.e., near neutrality), and the waters were slightly turbid or turbid. During benthic macroinvertebrate sampling, the waters were extremely turbid except at UT Fourth Creek (see forward Figures 7 and 9). A c a') 400H A 0 2000.0 L 1000.0 a J .

Low flow also reduces instream habitats such as undercut banks and root mats which may be out of the water and dry. Landuse Major landuse types were determined for each sub watershed based upon CGIA coverage 1993 —1995 (Figure 4). The percentage of developed land was greatest in the UT Fourth Creek watershed (-72 percent) although the entire watershed was only 2.5 square miles. The percentages of lands under cultivation and in forest were roughly equal at the four mainstem Fourth Creek sub watersheds. Most of the developed lands were above the Fourth Creek Site No. 2 (Figures 1 and 4). The percentages of developed land decreased from 22 to 12 percent between Fourth Creek Site Nos. 2 and 3 while the percentages of forested lands increased from 39 to 46 percent; the percentage of cultivated lands remained constant at about 39 percent. Approximately 40 to 50 percent of the four mainstem Fourth Creek sub watersheds were considered cultivated and approximately 45 percent forested. As a benthic macroinvertebrate reference site, Rocky Creek was more than three -fourths forested and less than one percent developed. Site Descriptions and Instream and Riparian Habitats Instream and riparian habitats at all sites except Rocky and LIT Fourth Creeks were of low quality; the habitat scores were generally less than 50 (Tables 4 and 5). Habitat characteristics that were severely degraded were the lack of instream habitats, bottom substrates of primarily sand, shallow and sand -filled pools, a general lack of gravel or cobble riffles, and very unstable, easily eroded banks. Very sandy streams (including Third, Fifth, Olin, and Patterson Creeks) are the rule in Iredell County. The canopy at the Fourth Creek sites was good and the riparian zone was usually wide except at Site No. 1. Everywhere along Fourth Creek there remained evidence of the extremely high 2003 winter flows, including large woody debris and obstructions, sloughing and exposed banks with minimal stabilizing vegetation, recent bank erosion, and tires, plastics, lumber, and other domestic items in the stream and along the shoreline. Thus, these sites appeared to be chronically impacted by high, flashy flows that are typical of urbanized watersheds. These flows erode the banks, contribute large quantities of sediment into the system and channel, render the water consistently turbid, and lead to undercutting of the banks which causes many large trees to fall into the channel.

Fourth Creek Site No. 1 at SR 1930 The immediate surrounding area contained a mixture of agriculture and residential landuse although the watershed was only four percent developed. The substrate was nearly all sand and during benthic sampling the single riffle area had been disturbed by recent high flows. There were some breaks in the riparian zone and the vertical banks were severely eroding, leading to the collapse into the stream of large trees along the shoreline (Figures 5 and 6). Most of the benthic fauna was associated with snag habitats or root mats. 11 Figure 5. Upstream (View A) and downstream (View B) views of Fourth Creek at SR 1930, Iredell County, July 30, 2003.

Fourth Creek Site No. 2 at SR 2320 The substrate was nearly all sand near the bridge, however more cobble was found further upstream within the reach sampled by the fish community program. There were no rock riffles and the vertical banks were severely eroding (Figure 7). Figure 7. Downstream (A, June 06, 2003) and upstream (B, July 29, 2003) views of Fourth Creek at SR 2320, Iredell County. 12 Fourth Creek Site No. 3 at SR 2308 There was no rock -riffle habitats in this section of Fourth Creek, although there were chutes with large sticks and large logs in the current; good leaf pack and snag habitats also were present. There were no breaks in the riparian zones, although the vertical banks were severely eroding and were contributing large amounts of sediment into the stream during high flow events (Figure 8). The substrate was primarily sand, but clay and cobble substrates also were found in the sampled reach. Figure 8. Upstream view showing turbid water and large woody debris (View A) and vertical, recently -eroded banks (View B) of Fourth Creek at SR 2308, Iredell County, July 29, 2003. The vertical bank was more than 5 m in height. Fourth Creek Site No. 4 at SR 1985 This is the most downstream site on Fourth Creek and it was very turbid during the June 2003 benthic collections (Figure 9). Most of the benthic fauna were associated with the snag habitats. The stream was uniformly wide and shallow. The substrate was all sand and there were no riffles. The riparian areas were intact and wide. Figure 9. Fourth Creek at SR 1985, Rowan County, June 06, 2003 (A) and July 29, 2003 (B). Morrison Creek at SR 1907 Morrison Creek is the only major tributary of Fourth Creek upstream of Statesville. Like Fourth Creek, it has very poor habitat with a sandy substrate, no pools or riffles, and severe bank erosion. The water was very turbid following heavy rainfall (Figure 10). The stream was very entrenched with frequent breaks in the riparian buffer zone. 13 Figure 10. Morrison Creek (A) at SR 1907 and UT Fourth Creek (B) at SR 2322, Iredell County. UT Fourth Creek at SR 2322 This three meter -wide stream drains a highly urbanized section of Statesville. During benthic sampling, the water was very clear (in spite of recent rains), and this site had fairly good macroinvertebrate habitats. This stream was the only site in the Statesville area with good rocky riffles (Figure 10). The rocks were very "clean", however, suggesting that periphyton growths were reduced in the stream. It is possible that this small stream stops flowing during drought periods. Rocky Creek at SR 1854 Rocky Creek was the nearest stream that could be used as a benthic reference site. In contrast to the sites within the Fourth Creek watershed, Rocky Creek had high quality instream and riparian habitats with little bank erosion, good riffles and pools, and a wide riparian buffer (Figure 11). The surrounding land (mostly agriculture) appeared to be well -managed and most of the watershed is forested (Figure 4). Figure 11. Rocky Creek at SR 1854, Iredell County. Benthic Macroinvertebrate Community Spatial Results (Appendix 9 and Table 6) UT Fourth Creek Only one highly tolerant EPT taxon (Baetis flavistriga) was abundant at this site even though the habitat was surprisingly good at this site. This indicated very severe water quality problems. This stream, however, also may be influenced by lack of flow during drought periods as were found in 2002. Due to the stream's small size, the community was not rated. 14 Fourth Creek Site No. 1 and Morrison Creek Most of the benthic fauna at the two headwater sites was associated with leafpacks, snags, or root mats along the stream margin. Although only EPT taxa were collected, field notes indicated that tolerant taxa (especially Chironomidae) were dominant. Both sites were rated Good -Fair. Perlesta was abundant at both sites, but long-lived stoneflies were rare or absent. Scour effects were most severe in Morrison Creek, as no baetid species were abundant. Site No. 1 had five baetid species; of which one (B. propinquus) was abundant and three were common. Unusual taxa collected included a mayfly, Cercobrachys, which is usually limited to the Broad River basin. Fourth Creek Site No. 2 (below urban section of Statesville) Site No. 2 was also rated Good -Fair, but there was a decline in EPT taxa richness between Site Nos. 1 and 2. The 10-sample EPT S declined from 23 to 17 and the EPT BI increased from 5.0 to 5.4. The same tolerant baetid (Baetis flavistriga) that was found at the urban site (UT Fourth Creek) was also abundant at this site. Fourth Creek Site No. 3 (below Statesville's WWTP) Water quality further declined between Site Nos. 2 and 3. EPT S was low (11) at Site No. 3 and the EPT BI was relatively high (5.9). This site was rated Fair based on EPT S, but rated Good -Fair based on the Bl. Because EPT N was low, the overall rating was Fair. The high flow and scour that preceded the June 2003 sampling would have reduced the abundance of most pollution -indicator groups, especially those associated with silt and slow -current habitats. For this reason, a high BI during this survey was not expected. Fourth Creek Site No. 4 The benthic community indicated recovery relative to Site No. 3 (from Fair to Good -Fair). EPT S, EPT N, and EPT BI were similar to those recorded for Site No. 1. Rocky Creek This site was rated Excellent based on high EPT S (41) and the presence of many intolerant taxa. The 2003 results were similar to those of prior DWQ surveys. The Excellent bioclass ification indicated that the high rainfall prior to the June 2003 sampling should not have affected the EPT S at the other sites. Table 6.

This did not indicate any significant decline in water quality because between -year differences were very small. Spring collections (June) produced slightly greater EPT S than summer collections (July or September), but the BI was very stable (6.0-6.2). Table 7.

The BI was consistently high and the EPT N was consistently low. Very high flows, as witnessed in 2003, tend to reduce the abundance and diversity of the benthic macroinvertebrate fauna, especially those taxa associated with slower currents. However, the resulting low EPT S (relative to the upstream site) was offset by a reduction in the BI. Some of the most tolerant taxa (e.g., Oligochaeta and Chironomidae) were removed by scour during high flows, resulting in low abundances of these pollution -indicator groups. Total EPT S (for all years) was 31 upstream, but only 20 downstream. Fish Community (Appendix 3) Seven fish community samples have been collected from Fourth Creek since 1996; four of these samples were collected from the basinwide site at SR 1985 in Rowan County (Site No. 4). The fish fauna of the Fourth Creek watershed and at each site was rather depauperate in species and individuals. Only 25 species have been documented at these four sites and no more than 15 species have been collected at any site at any particular time (Table 8). At most sites, the number of species and the number of fish collected was only about one-half the number expected for a stream of its size. For example, at Site No. 4 only 11 species were collected, whereas based upon regional reference sites, at least 20 species should be found at this site. Almost one-fourth of the 25 species known from the watershed (Common carp, Red shiner, Fathead minnow, Channel catfish, Green sunfish, and Spotted bass) are not native to the Yadkin River basin. At Site No. 4, 4 of the 11 species were exotics. More than one-half of the species (13 out of the 25 species) in the watershed are classified as tolerant species. Intolerant species known to occur in the middle portion of the Yadkin River basin (Piedmont darter, Highback chub, and Fieryblack shiner) are absent in Fourth Creek. The dominant species at most sites was the Bluehead chub; a species generally indicative of some nutrient enrichment. I. Table 8.

In 2003, 3 of the 4 fish communities were rated Poor (NCIBI <_ 34, Site No. 2 was rated a low Good -Fair (NCIBI = 42). As compared to the regional reference sites, these poorly rated communities were generally lacking in individual fish, species of darters, intolerant species, and long-lived piscivores,; there was an abundance of tolerant fish at most sites. The overall species diversity, diversity of long-lived suckers, and reproductive efforts were only moderate and the trophic structure was slightly skewed towards omnivores+herbivores. As compared to the sites rated as Poor, Site No. 2 had a overall greater diversity of species (including darters and sunfish+bass), slightly more fish, a lesser percentage of tolerant fish, and a greater percentage of piscivores. CONCLUSION During the past several years flows in Fourth Creek have been extreme — from as little as 1 cfs during droughts to more than 4,000 cfs during the winter of 2003. The stream also has elevated conductivity, turbidity, and fecal coliform bacteria, and degraded instream and riparian habitats. The sources of these stressors (causes of impairment) are the historic poor landuse practices in the watershed, the current urban landuse practices surrounding the City of Statesville, the erosive soils throughout the watershed, and the wastewater treatment plant. These stressors have resulted in degraded fish communities (Table 9). The fish communities were sparse and dominated by species indicative of some nutrient enrichment, tolerance to pollution, variable flows, and degraded instream habitats. The benthic community did not show as extreme degradation as did the fish community, except at the site immediately below Statesville's WWTP. Table 9.

Permit: The facility is as described in the permit. Facility Site Review / Operations and Maintenance: Michael Evans, the listed ORC of the facility, was not available due to having been called up for active military service. David Jones, the back-up operator, is currently acting as the surrogate for the ORC. Be advised that 15A NCAC 08G .0205 states that the back-up operator may serve as the surrogate for the ORC for a period not to exceed 20% of the system visits per calendar year or more than 120 consecutive days when the ORC is absent due to vacancy or illness. A process control program consisting of pH, dissolved oxygen, temperature, sludge settleability, and sludge depth measurements, and alkalinity, MLSS, and MLVSS testing is performed daily. The facility utilizes an on -site generator for emergency power and is a participant in the Load Management Program with Duke Power. When active in the Load Management Program the on -site generator runs at least weekly, at other times the generator is exercised every 10 days. The Division of Air Quality permits the on -site generator (ID # 258). The surface of the discharge section of one of the chlorine contact chambers was covered with floating sludge and debris. Because the outlet of the chlorine contact chamber is below the surface of the water, the sludge/debris appeared to be contained in the chlorine contact chamber. Records/Reports: Records and reports are maintained in accordance with permit requirements and consist of monthly monitoring reports, chain -of -custody forms, rainfall records, process control data, residuals management records, instrument calibration records, flow charts, operations and maintenance report, and an ORC log. Laboratory: The on -site laboratory (Certificate # 181) appeared to be well managed and organized. All QA/QC logs were easily accessible and up-to-date. Pace Labs - Huntersville conducts metals, TKN, and MBAS analyses and Pace Labs - Asheville performs aquatic toxicity testing. The remaining testing and analyses required by the permit are conducted in-house. Statesville Fourth Creek WWTP NPDES Permit No. NCO031836 Page 3 Self -Monitoring Program: Monthly monitoring reports were reviewed for the period January through December 2002. No violations were reported during the period. Samples are collected and stored at 4°C according to refrigerator logs. Influent and effluent composite samplers were both at 4°C at the time of this inspection. Flow Measurement: Flow is measured at the effluent by means of an ultra sonic flow meter. A chart recorder is located in the operator's office. The flow meter is calibrated twice yearly by Carolina Technical Services. Sludge Disposal: Dewatered sludge is treated using the N-Viro Soil alkaline process (Class A residuals, Permit No. WQ0006245) and is available to the public. The City also has a land application program managed by Bio-Gro (Land Application Permit No. WQ0014543, Class B residuals). Effluent/Receiving Waters: The effluent was cloudy and no foam or color were observed. The facility discharges to Fourth Creek, which is class C water in the Yadkin River Basin (YAD06). { 'i4_._oa., h..`' Michael F. Easley, Governor William G.

The original report failed to average the dissolved oxygen readings for May 15, 2002, which resulted in a Notice of Violation. Daily records from that date was 5.3 mg/l, which is within compliance limits. Further we have determined that the operators were not taking the grab sample for D.O. in the most representative location, hence the site has been moved to the downstream side instead of the upstream side of the flume to be more representative.

Kid, OCT 1 e )002 Dear Mr. Gleason, Attached please find a copy of the amended report for May, 2002 for the Fourth Creek WWTP Permit No. NC0031836. The original report failed to average the dissolved oxygen readings for May 15, 2002, which resulted in a Notice of Violation. Daily records from that date indicate that the average dissolved oxygen for that date was 5.3 mg/ 1, which is within compliance limits. Further we have determined that the operators were not taking the grab sample for D.O. in the most representative location, hence the site has been moved to the downstream side instead of the upstream side of the flume to be more representative. If I can provide any other information, please feel free to contact me at 704-878-3438.
