See Part 1.2.3 for test procedures.

See Part 3.4 for biomonitoring test and reporting requirements.

See below for percent removal calculations.

For purposes of monitoring and reporting for permit compliance with effluent limits the location of Outfall 001 is to be at the wastewater treatment plant site located off Fredonia Loop Road in

Haywood County, Tennessee, after treatment and prior to introduction of treated wastewater into the effluent force main. For purposes of sign placement and identification of the outfall structure location, the location of Outfall 001 shall be the actual discharge location to the

Mississippi River at mile 768 in Tipton County.

Direct discharges of chlordane, dioxins and polychlorinated byphenyls (PCBs) shall meet the most stringent applicable Tennessee state water quality standard applicable to support use designations of the Mississippi River at mile 768 and are only authorized pursuant to a modification of this permit to establish a sampling and reporting frequency for the respective pollutant to comply with the total daily maximum load (TMDL) approved for implementation

July 25, 2008, or its most current version.

The permittee may collect more samples than specified as the monitoring frequency in the permit. Samples may not be collected at intervals of less than 12 hours. For the purpose of determining the geometric mean, individual samples having an E. coli group concentration of less than 1 per 100 mL shall be considered as having a concentration of 1 per 100 mL. In addition, the concentration of the E. coli group in any individual sample shall not exceed a specified maximum amount.

Total residual chlorine (TRC) monitoring shall be applicable when chlorine, bromine, or any other oxidants are added. The acceptable methods for analysis of TRC are any methods specified in Title 40 CFR § 136 as amended, so long as the requirements of Tennessee Rule 0400-

40-03-.05(8) are met. The method detection limit (MDL) should be determined in accordance with 40 CFR § 136 as amended, Appendix B. The MDL for TRC shall not exceed 0.05 mg/l unless the permittee demonstrates that its MDL is higher. The permittee shall retain the documentation that justifies the MDL and have it available for review upon request. In cases where the permit limit is less that the MDL, the reporting of TRC at less than the MDL shall be interpreted to constitute compliance with the permit.

For CBOD5 and TSS, the treatment facility shall demonstrate a minimum of 85% removal efficiency on a monthly average basis. This is calculated by determining an average of all daily https://publications.tnsosfiles.com/rules/0400/0400-40/0400-40.htm influent concentrations and comparing this to an average of all daily effluent concentrations.

The formula for this calculation is as follows:

(1 − 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 𝑜𝑓 𝑑𝑎𝑖𝑙𝑦 𝑒𝑓𝑓𝑙𝑢𝑒𝑛𝑡 𝑐𝑜𝑛𝑐𝑒𝑛𝑡𝑟𝑎𝑡𝑖𝑜𝑛𝑠 𝑎𝑣𝑒𝑟𝑎𝑔𝑒 𝑜𝑓 𝑑𝑎𝑖𝑙𝑦 𝑖𝑛𝑓𝑙𝑢𝑒𝑛𝑡 𝑐𝑜𝑛𝑐𝑒𝑛𝑡𝑟𝑎𝑡𝑖𝑜𝑛𝑠 ) ∗ 100% = % 𝑟𝑒𝑚𝑜𝑣𝑎𝑙

This treatment facility will also demonstrate 40% daily minimum removal of CBOD5 and TSS based on each daily composite sample. The formula for this calculation is as follows:

(1 − 𝑑𝑎𝑖𝑙𝑦 𝑒𝑓𝑓𝑙𝑢𝑒𝑛𝑡 𝑐𝑜𝑛𝑐𝑒𝑛𝑡𝑟𝑎𝑡𝑖𝑜𝑛 𝑑𝑎𝑖𝑙𝑦 𝑖𝑛𝑓𝑙𝑢𝑒𝑛𝑡 𝑐𝑜𝑛𝑐𝑒𝑛𝑡𝑟𝑎𝑡𝑖𝑜𝑛 ) ∗ 100% = % 𝑟𝑒𝑚𝑜𝑣𝑎𝑙

Each daily load is calculated by multiplying the day’s sample concentration (mg/L) by the effluent flow rate (MGD) for the day the sample was collected and the conversion factor 8.34 lbs/gal.

𝐿𝑜𝑎𝑑 = ( 𝐸𝑓𝑓𝑙𝑢𝑒𝑛𝑡

The average pound per quarter is the mathematical average where the sum of all the calculated loads during the current quarter is divided by the number of calculated loads.

1.2. MONITORING PROCEDURES

Representative Sampling

Samples and measurements taken in compliance with the monitoring requirements specified herein shall be representative of the volume and nature of the monitored discharge and shall be taken after treatment and prior to mixing with uncontaminated stormwater runoff or the receiving stream. Appropriate https://apex.tdec.tn.gov:7777/apex/f?p=111:51:7059563386569:::51:P51_PERMIT_NUMBER:TN0081906 https://apex.tdec.tn.gov:7777/apex/f?p=111:51:7059563386569:::51:P51_PERMIT_NUMBER:TN0081906 flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be installed and calibrated by a qualified source at least once every 12 months1, and maintained to ensure that the accuracy of the measurements is consistent with accepted capability of that type of device. Devices selected shall be capable of measuring flows with a maximum deviation of plus or minus 10% from the true discharge rates throughout the range of expected discharge volumes.

Composite samples must be proportioned by flow at the time of sampling.

Aliquots may be collected manually or automatically. The sample aliquots must be maintained at ≤ 6°C during the compositing period, or as otherwise specified in 40 CFR §136 or in the method.

Raw wastewater must be sampled at various places in the collection system, if necessary, to implement the industrial pretreatment program and to support any variance from the percent removal requirements for secondary treatment allowed per 40 CFR 133.103(d).

Samples and measurements taken in compliance with the monitoring requirements specified above shall be representative of the volume and nature of the monitored discharge, and shall be taken at the following location(s):

Influent samples must be collected prior to mixing with any other wastewater being returned to the head of the plant, such as sludge return. Those systems with more than one influent line must collect samples from each and proportion the results by the flow from each line.

Effluent samples must be representative of the wastewater being discharged from the POTW and collected prior to mixing with any other discharge. The sampling point(s) can be a different point for different parameters but must be after all treatment for that parameter or all expected changes. Specifically:

a) POTW effluent samples must be collected ahead of reverse osmosis retentate pollutants being reintroduced back in the outfall line.

b) The chlorine residual must be measured after the chlorine contact chamber and any de-chlorination.

1 The Division expects for permittees to meet EPA’s guidance on proper operation and maintenance of flow measurement devices, as stated in the NPDES Compliance Inspection Manual.

https://www.epa.gov/sites/production/files/2017-01/documents/npdesinspect.pdf

c) Samples for E. coli can be collected at any point between completion of disinfection and the actual discharge.

d) The permittee shall measure dissolved oxygen at the treatment facility prior to entering the multi-mile outfall line to demonstrate aerobic conditions have been maintained in the treatment process.

e) Total suspended solids (TSS) and settleable solids can be collected at any point after the final clarifier.

f) Biomonitoring tests (if required) shall be conducted on final effluent.

Sampling Frequency

The permittee should report “No Discharge” on Discharge Monitoring Reports

(DMRs) only if a permitted outfall does not discharge at any time during the monitoring period. If the outfall discharges effluent at any time during the monitoring period, the permittee must provide at least one sampling result from the effluent of that outfall.

If the required monitoring frequency is once per month or 1/month, the monitoring period is one month. If the discharge occurs during only one day in that period, the permittee must sample on that day and report the results of analyses accordingly.

Test Procedures

a) Test procedures for the analysis of pollutants shall conform to regulations published pursuant to Section 304 (h) of the Clean Water Act (the "Act"), as amended, under which such procedures may be required.

b) Unless otherwise noted in the permit, all pollutant parameters shall be determined using sufficiently sensitive methods in Title 40 CFR § 136, as amended, and promulgated pursuant to Section 304 (h) of the Act. The chosen methods must be sufficiently sensitive as required in state rule 0400-40-03-

.05(8).

c) If the minimum level of quantification (ML) for all methods available in accordance with 40 CFR § 136 are above the stated permit limit or applicable water quality criteria for that parameter, then the method with the lowest ML shall be used.

d) Where the analytical results are below the method detection limit (MDL), the permittee shall report the actual laboratory MDL and ML values. See Section

1.3.6. for instructions regarding reporting less than detection.

e) When there is no analytical method that has been approved under 40 CFR

§136 or required under 40 CFR chapter I, subchapter N or O, and a specific method is not otherwise required by the Director, the permittee may use any suitable method but shall provide a description of the method. When selecting a suitable method, factors such as a method’s precision, accuracy, or resolution must be considered when assessing the performance of the method.

Recording of Results

For each measurement or sample taken pursuant to the requirements of this permit, the permittee shall record the following information:

i. The date, exact place, and time of sampling or measurements;

ii. The individual(s) who performed the sampling or measurements;

iii. The date analyses were performed;

iv. The individual(s) who performed the analyses;

v. The laboratory where the analyses were performed;

vi. The analytical techniques or methods used; and

vii. The results of such analyses.

Records Retention

The permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by this permit, and records of all data used to complete the application for this permit, for a period of at least 3 years from the date of the sample, measurement, report or application. This period may be extended by request of the Director at any time.

1.3. REPORTING

Monitoring Results

Monitoring results shall be recorded monthly and submitted monthly on

Discharge Monitoring Reports (DMRs) using EPA’s NetDMR website. The first DMR is due on the 15th of the month following permit effectiveness. Subsequent DMRs shall be submitted through NetDMR no later than 15 days after the completion of the reporting period. In compliance with the Federal NPDES Electronic Reporting

Rule, DMRs may not be submitted via email under any circumstances.

https://cdxnodengn.epa.gov/net-netdmr/

Discharge Monitoring Reports and any other information or report must be signed and certified by a responsible corporate officer as defined in Tennessee

Rules, Chapter 0400-40-05-.07(2)(i), a general partner or proprietor, a principal municipal executive officer or ranking elected official, or his or her duly authorized representative. Such authorization must be submitted in writing and must explain the duties and responsibilities of the authorized representative.

In the event that electronic reporting is unavailable, the permittee shall comply with reporting conditions provided in Section 1.7.

Additional Monitoring by Permittee

If the permittee monitors any pollutant more frequently than required by the permit using test procedures approved under 40 CFR § 136, or as specified in the permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted in the DMR or other reporting form specified by the Commissioner. Such increased frequency shall also be indicated.

Falsifying Results and/or Reports

Knowingly making any false statement on any report required by this permit or falsifying any result may result in the imposition of criminal penalties as provided for in Section 309 of the Federal Water Pollution Control Act, as amended, and in

§ 69-3-115 of the Tennessee Water Quality Control Act.

Overflow, Release, and Bypass Reporting

1.3.5.1. Event Report Requirements

For the purpose of this section, “events” are known as instances of sanitary sewer overflows, releases, upsets, and bypasses. These events shall be reported through

MyTDEC Forms according to the following conditions:

a) Events that are not a threat to human health and the environment shall be reported using MyTDEC Forms no later than 15 days following the completion of the DMR reporting period.

b) Events that could cause a threat to human health or the environment, as defined in Section 2.3.1.a., shall be reported using MyTDEC Forms no later than 5 days after becoming aware of the non-compliance.

In both cases, the event report must contain the following:

i. Start date;

ii. Estimated duration in hours;

iii. Estimated volume in gallons;

iv. Type of event;

v. Type of structure (e.g., manhole);

vi. Types of human health and environmental impacts;

vii. Location (i.e., latitude and longitude);

viii. The name of receiving water (if applicable);

ix. Description of the cause;

x. The steps being taken to correct, reduce, eliminate, and prevent recurrence of the noncompliance; and

xi. The next downstream pump/lift station using the permittee’s naming conventions.

In the event that MyTDEC Forms is not functioning, the permittee shall comply with reporting conditions provided in Section 1.7.

1.3.5.2. DMR Report Requirements

On the DMR, the permittee must separately report:

i. The total number of sanitary sewer overflows for the reporting month; and

ii. The total number of dry-weather sanitary sewer overflows for the reporting month.

On the DMR, sanitary sewer overflows are coded “SSO, Dry Weather” and “SSO, Wet Weather”. Each discrete location of a sanitary sewer overflow shall be reported as a separate value.

Reporting Less Than Detection; Reporting Significant Figures

For the purpose of evaluating compliance with the permit limits established herein, where certain limits are below the minimum level (ML) of 40 CFR § 136 approved analytical methods, compliance will be demonstrated when a non-detect result is obtained using the most sensitive method available. The results of non-detect analyses, in this case, shall be reported as Below Detection Limit (BDL) or “NODI = B” in NetDMR. Reporting examples are provided below.

Reporting Example 1: If the permit limit is 0.02 mg/L with a method detection limit (MDL) of 0.05 mg/L and no detection is shown, the permittee must report

“BDL” or “NODI = B” on DMRs in NetDMR. Whenever “BDL” or “NODI = B” is reported, the actual MDL must be reported in the DMR comments or in an attachment submitted in NetDMR.

Reporting Example 2: If the permit limit is 0.02 mg/L with an MDL of 0.05 mg/L and detection is shown, the actual detected value must be reported.

Reporting Example 3: If the permit limit is 0.02 mg/L with an MDL of 0.01 mg/L and no detection is shown, the permittee must report less than MDL (<0.01 mg/L in this case).

For purposes of calculating averages, zero may be assigned for values less than the MDL, the numeric value of the MDL may be assigned for values between the

MDL and the ML. If the average value is less than the MDL, the permittee must report “less than {numeric value of the MDL}" and if the average value is less than the ML, the permittee must report "less than {numeric value of the ML}.” If a value is equal to or greater than the ML, the permittee must report and use the actual value. The resulting average value must be compared to the compliance level, the

ML, in assessing compliance.

Reported results are to correspond to the number of significant figures (decimal places) set forth in the permit conditions. The permittee shall round values, if allowed by the method of sample analysis, using a uniform rounding convention adopted by the permittee.

Outlier Data

Outlier data include analytical results that are probably false. The validity of results is based on operational knowledge and a properly implemented quality assurance program. False results may include laboratory artifacts, potential sample tampering, broken or suspect sample containers, sample contamination or similar demonstrated quality control flaw.

Outlier data are identified through a properly implemented quality assurance program, and according to ASTM standards (e.g. Grubbs Test, ‘h’ and ‘k’ statistics).

Furthermore, outliers should be verified, corrected, or removed based on further inquiries into the matter. If an outlier was verified (through repeated testing and/or analysis), it should remain in the preliminary data set. If an outlier resulted from a transcription or similar clerical error, it should be corrected and subsequently reported.

Therefore, only if an outlier was associated with problems in the collection or analysis of the samples and as such does not conform with the Guidelines

Establishing Test Procedures for the Analysis of Pollutants (40 CFR §136), can it be removed from the data set and not reported on DMRs. Otherwise, all results

(including monitoring of pollutants more frequently than required at the location(s) designated, using approved analytical methods as specified in the permit) should be included in the calculation and reporting of the values required in the DMR form. The permittee should use the “comment” section in NetDMR to explain any potential outliers or dubious results.

1.4. COMPLIANCE WITH SECTION 208

The limits and conditions in this permit shall require compliance with an area-wide waste treatment plan (208 Water Quality Management Plan) where such approved plan is applicable.

1.5. REOPENER CLAUSE

This permit shall be modified, or alternatively revoked and reissued, to comply with any applicable effluent standard or limitation issued or approved under

Sections 301(b)(2)(C) and (D), 307(a)(2), and 405(d)(2)(D) of the Clean Water Act, as amended, if the effluent standard, limitation, or sludge disposal requirement so issued or approved:

a) Contains different conditions or is otherwise more stringent than any condition in the permit; or

b) Controls any pollutant or disposal method not addressed in the permit.

The permit as modified or reissued under this paragraph shall also contain any other requirements of the Act then applicable.

1.6. SCHEDULE OF COMPLIANCE

Full compliance and operational levels shall be attained from the effective date of this permit, except for conditions under compliance schedules. See Section 1.1.
