Box 67 Jefferson, NC 28640 SUBJECT: Compliance Evaluation Inspection Town of Jefferson WWTP NPDES Permit # NCO021709 Ashe County Dear Mr. Church: Donald R. van der Vaart Secretary A Compliance Evaluation Inspection was performed on the facility by George Smith on October 9, 2015. Mr. Tim Church, ORC, Grade IV was present for the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. Permit Your new NPDES permit became effective September 1, 2011 and expires March 31, 2016. It is recommended that the Town register for eDMR. It will be a permit requirement in your next permit cycle. Please remember to submit your NPDES permit renewal application EPA Form 2A. Send to: Division of Water Resources WQ Permitting Section - NPDES 1617 Mail Service Center Raleigh, NC 27699-1617 Records & Reports The facility performs and documents process control of the following: microscopic examination, settleability, MLSS, pH (clarifier, oxidation ditch, and digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and blanket height with a sludge judge. These records were in excellent order. The Performance Annual Report for the calendar year 2014 was sent to the NPDES Unit on June 9, 2015. Facility Site Review There are four influent pumps (two-300gpm and two-400gpm). The 3/8-inch automatic bar screen was properly operating. The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor. The three rings of the ditch have sufficient dissolved oxygen. This treatment unit is performing very well. 450 W Hanes Mill Rd., Suite 300, Winston-Salem, NC 27105 Phone: 336-776-98001 Internet: www,ncdenr.gov An Eoual O000rtunity y Affirmative Action Employer — Made in part by recycled paper The secondary clarifier's effluent over the weirs was clear. Both units were functioning very well, and were well maintained. There was a very small amount of floating paver on the surface, which is discharged from the county jail. The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was clear. The chlorine contact chamber contained a clear effluent with no solids present. Flow Measurement The flow is measured with a 90' V-notch sharp crested weir. A Chessel type flow recording device is used with a seven day circular chart. The calibration was performed and documented by the Town of Jefferson on July 28, 2015. Laboratory The municipal lab is field certified #5206, and performed the following: Total Residual Chlorine, Dissolved Oxygen, pH, and temperature. The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using the flow thru cell. The annual five point calibration is scheduled to be performed during October 2015. The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer. A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NIST. Effluent/Receiving Waters The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor. The effluent showed no adverse to the stream. Operations & Maintenance The Class II facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters, Back-up ORC, Grade II. There were four biological rotators that had rebuilt drive motors. There are two remaining to be rebuilt. The oxidation ditch is maintained at a MLSS of 2730 mg/L. The settleable solids are 42%. The Sludge Volume Index (SVI) is 153. Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite is used for dechlorination, which is prepared and dissolved in water as needed. Self -Monitoring Program The effluent is sampled by composite flow proportion method at 150 ml/10,000 gallons using Isco model 3710 FR samplers with refrigerator. They are well maintained, clean tubing and temperature is 1 °C. All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters. PPPPPPP- A review of the monthly self -monitoring reports from January 2015 through July 2015 showed no limit violations. Sludge Disposal The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with approximately volume 50% left to waste. The sludge dryer appears to be well maintained. The facility generates approximately 50% Class A and 50% Class B residuals. The compliance evaluation inspection is considered satisfactory. Mr. Church does a very good job maintaining the POTW.

Box 67 Jefferson, NC 28640 SUBJECT: Compliance Evaluation Inspection Town of Jefferson WWTP NPDES Permit # NCO021709 Ashe County Dear Mr. Church: A Compliance Evaluation Inspection was performed on the facility by George Smith on October 16, 2013. Mr. Tim Church, ORC, Grade IV was present for the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. Permit Your new NPDES permit became effective September 1, 2011 and expires March 31, 2016. Records & Reports The facility performs and documents process control of the following: microscopic examination, settleability, MLSS, pH (clarifier, oxidation ditch, and digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and blanket height with a sludge judge. These records were in excellent order. The Performance Annual Report for the calendar year 2012/13 will be compiled and sent to the NPDES Unit in the next few weeks. Facility Site Review There are four influent pumps (two-300gpm and two-400gpm). The 3/8-inch automatic bar screen was properly operating. The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor. The three rings of the ditch have sufficient dissolved oxygen. This treatment unit is performing very well. 585 Waughtown Street North Carolina 27360 Phone: 336-771-50001 Fax: 336-771-4630 Internet:: www.ncwaterouality.ora An Eaual O000rtunitv\Affirmative Action Emolover Compliance Evaluation Inspection October 21, 2013 Page 2 of 3 The secondary clarifiers had very slight straggler flock coming over the weirs. The effluent over the weirs was clear. Both units were functioning very well, and were well maintained. There were numerous pieces of paper floating in the secondary clarifiers and the tertiary filter. The small papers were collected along the clarifier weirs, scum trough, and floated in the tertiary filter bed. There is a potential for operation and maintenance problems in both the plant and collection system. The papers are coming from the county jail. Chewing gum wrappers and similar paper products are dumped into a sink and sent through a grinder (muffin monster). Recommend the Town suggest an alternate disposal method for the jail. The county jail may be placed in the pretreatment program as an industrial user for adverse impacts to the POTW. The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was clear. The chlorine contact chamber contained a clear effluent with no solids present. Flow Measurement The flow is measured with a 90' V-notch sharp crested weir. A Chessel type flow recording device is used with a seven day circular chart. The instantaneous flow at the time of the inspection is 0.255 MGD. The calibration was performed and documented by the Town of Jefferson on October 14, 2013. Laboratory The municipal lab is field certified #5206, and performed the following: Total Residual Chlorine, Dissolved Oxygen, pH, and temperature. The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using the flow thru cell. The annual five point calibration was performed on June 29, 2012, and is scheduled for calibration in October 2013. The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer. A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NIST. Effluent/Receiving Waters The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor. The effluent did cause the receiving waters did have a slight amount of foam on the surface which dissipated approximated 20-feet downstream. This was noted in previous years. r Compliance Evaluation Inspection October 21, 2013 Page 3 of 3 Operations & Maintenance The Class II facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters, Back-up ORC, Grade II. The oxidation ditch is maintained at a MLSS of 2560 mg/L. The settleable solids are 39%. The Sludge Volume Index (SVI) is 164. Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite is used for dechlorination, which is prepared and dissolved in water as needed. Self -Monitoring Program The effluent is sampled by composite flow proportion method at 150 ml/10,000 gallons using Isco model 3710 FR samplers with refrigerator. They are well maintained, clean tubing and temperature is 0°C. All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters. A review of the monthly self -monitoring reports from January 2013 through July 2013 showed no limit violations. Sludge Disposal The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with approximately volume 40% left to waste. The sludge dryer appears to be well maintained. The facility generates approximately 50% Class A and 50% Class B residuals. The compliance inspection is considered satisfactory. Mr. Church does a very good job maintaining the POTW.

Mr. Tim Church, ORC, Grade IV along with Mr. Fred Walters, Back-up ORC, Grade II were present for the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. Permit Your new NPDES permit became effective September 1, 2011 and expires March 31, 2016. Records & Reports The facility performs and documents process control of the following: microscopic examination, settleability, MLSS, pH (clarifier, oxidation ditch, and digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and blanket height with a sludge judge. These records were in excellent order. The Performance Annual Report for the calendar year 2012 will be compiled and sent in the next few weeks. Facility Site Review There are four influent pumps (two-300gpm and two-400gpm). The 3/8-inch automatic bar screen was properly operating. The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor. The three rings of the ditch have sufficient dissolved oxygen. This treatment unit is performing very well. The secondary clarifiers had very slight straggler flock coming over the weirs. The effluent over the weirs was clear. Both units were functioning very well, and were well maintained. The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was clear. Both filters were backwashing at the time of the inspection.

Flow Measurement 194 The flow is measured with a 90' V-notch sharp crested weir. A Chessel type flow recording device is used with a seven day circular chart. The instantaneous flow at the time of the inspection is 0.605 MGD. The calibration was performed and documented by the Town of Jefferson on January 26, 2012. Laboratory The municipal lab is field certified #5206, and performed the following: Total Residual Chlorine, Dissolved Oxygen, pH, and temperature. The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using the flow thru cell. The annual five point calibration was performed on June 29, 2012. The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer. A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NBS. Effluent/Receiving Waters The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor. The effluent did cause the receiving waters did have a slight amount of foam on the surface which dissipated approximated 20-feet downstream. There was a beaver dam at the wooden foot bridge. The creek was much higher elevation than normal. The dam should be removed in order to prevent water from backing -up into the plant. Operations & Maintenance The Grade III facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters, Back- up ORC, Grade U. All treatment units in the facility were well maintained. The oxidation ditch is maintained at a MLSS of 2100 mg/L. The dissolved oxygen in the outer ring is 0.2 mg/L and the inner ring is 3 mg/L. Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite is used for dechlorination, which is prepared and dissolved in water as needed. Self -Monitoring Program The effluent is sampled by composite flow proportion method at 150 ml/10,000 gallons using Isco model 3710 FR samplers with refrigerator. They are well maintained, clean tubing and temperature is < 4°C. Compliance Evaluation Inspection October 15, 2012 Page 3 of 3 All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters. A review of the monthly self -monitoring reports from January 2012 through August 2012 showed no limit violations. Sludge Disposal The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with plenty of room for wasting solids. The sludge dryer appears to be well maintained. The facility generates approximately 50% Class A and 50% Class B residuals. The compliance inspection is considered satisfactory.

Box 67 Jefferson, NC 28640 SUBJECT: Compliance Evaluation Inspection Town of Jefferson WWTP NPDES Permit # NCO021709 Ashe County Dear Mr. Church: Dee Freeman Secretary A Compliance Evaluation Inspection was performed on the Grade III facility by George Smith on January 24, 2012. Mr. Tim Church, ORC, Grade IV along with Mr. Fred Walters, Back-up ORC, Grade H were present for the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. Permit Your new NPDES permit became effective September 1, 2011 and expires March 31, 2016. Please make yourself familiar with the new permit monitoring requirements Records & Reports The facility performs and documents process control of the following: microscopic examination, settleability, MLSS, pH (clarifier, oxidation ditch, and digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and blanket height with a sludge judge. These records were in excellent order. The Performance Annual Report for the calendar year 2011 will be compiled and sent in the next few weeks. Facility Site Review There are four influent pumps (two-300gpm and two-400gpm). The 3/8-inch automatic bar screen was properly operating. The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor. The three rings of the ditch have sufficient dissolved oxygen. This treatment unit is performing very well. The secondary clarifiers had some straggler flock coming over the weirs. The effluent over the weirs was clear. Both units were functioning very well, and were well maintained. The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was clear.

Flow Measurement C The flow is measured with a 90' V-notch sharp crested weir. A Chessel type flow recording device is used with a seven day circular chart. The instantaneous flow at the time of the inspection is 0.605 MGD. The calibration was performed and documented by the Town of Jefferson on January 26, 2012. Laboratory The municipal lab is field certified #5206, and performed the following: Residual chlorine, dissolved oxygen, pH, residue settleable, and temperature. The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using the flow thru cell. A five point calibration is performed annually. The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer. A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NBS. Effluent/Receiving Waters The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor. Operations & Maintenance The Grade III facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters, Back- up ORC, Grade II. All treatment units in the facility were well maintained. The oxidation ditch is maintained at a MLSS of 2800 mg/L. Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite is used for dechlorination. Self -Monitoring Program The effluent is sampled by composite flow proportion method at 150 ml/10,000 gallons using Isco model 3710 FR samplers with refrigerator. They are well maintained, clean tubing and temperature is < 4°C. All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters. A review of the monthly self -monitoring reports from January 2011 through November 2011 showed no limit violations. Compliance Evaluation Inspection February 1, 2012 Page 3 of 3 Sludge Disposal The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with plenty of room for wasting solids. The sludge dryer appears to be well maintained. The facility generates approximately 50% Class A and 50% Class B residuals. The compliance inspection is considered satisfactory.

Sullins Dee Freeman Director Secretary June 8, 2011 Mr. Tim Church, Water Resources Director Town of Jefferson P.O. Box 97 Jefferson, North Carolina 28640 Subject: Draft NPDES Permit Permit NCO021709 Jefferson WWTP Ashe County Dear Mr. Church: The Division of Water Quality (DWQ) has received your application for renewal and has drafted a NPDES permit for the above referenced facility. The draft permit authorizes the Town of Jefferson to discharge wastewater from the Jefferson WWTP to Naked Creek, a class C+ water in the New River Basin. The supplemental "+" symbol on the classification indicates that Naked Creek is subject to a special management strategy in the Outstanding Resource Waters rule to protect the downstream South Fork New Rivers. The draft permit includes discharge limitations/or monitoring requirements for flow, BODS, ammonia nitrogen, total suspended solids (TSS), dissolved oxygen, total residual chlorine, fecal coliform, copper, zinc, cyanide, lead, cadmium and several other parameters. Please note that the receiving stream, Naked Creek is also listed as an impaired waterbody on the North Carolina 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required. The following procedure has been implemented by DWQ: Total residual chlorine (TRC) compliance level changed to 50 ug/1 Effective March 1, 2008, the Division received EPA approval to allow a 50ug/l TRC compliance level. This change is due to analytical difficulties with TRC measurements. Facilities will still be required to report actual results on their monthly discharge monitoring report (DMR) submittals, but for compliance purposes, all TRC values below 50 ug/1 will be treated as zero. A footnote regarding this change has been added to the effluent limitations page in the draft permit and was included based on the facility's chlorination system. The following modifications are included in the draft permit. • A monthly average limit of 3.4 ug/1 and a daily maximum limit of 22.3 ug/l for cadmium have been added to the permit and will be sampled monthly. Results of a reasonable 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Results of a reasonable potential analysis on submitted data indicated there was reasonable potential to exceed the water quality standard instream. • Total lead will continue to be limited in the permit, and has been modified to a monthly average of 42.1 ug/l and a daily maximum of 50.3 ug/l. Lead will be sampled monthly. Results of a reasonable potential analysis on submitted data indicated there was reasonable potential to exceed the water quality standard instream. • Monitoring for copper and zinc will remain in the permit based on the results of the reasonable potential analyses, which indicated potential to exceed the water quality action level standard instream. Copper and zinc will now be monitored quarterly in conjunction with the whole effluent toxicity test. • The daily maximum limit for mercury will be deleted from the permit based on the results of the reasonable potential analysis which indicated there was no potential to exceed the water quality standard instream. However, quarterly monitoring for mercury will be included in the permit based on the evaluation of data and DWQ guidance. • Monitoring for total silver has been deleted from the permit. Results of a reasonable potential analysis on submitted data indicated there was no reasonable potential to exceed the water quality standard in the receiving stream. Silver should continue to be monitored during the pretreatment program plan. • Please note that there have been minor language changes and the addition of a new paragraph regarding data submittal in special condition A.2. Chronic Toxicity permit limit. (The new paragraph is located second from the end of the condition). At this time, the Division is submitting a notice to the newspapers of general circulation in Ashe County, inviting comments from you or your representative, the public and other agencies on the draft permit. The notice should be published on or about June 16th. Following a 30-day comment period, we will review all pertinent comments received and take appropriate action on the permit issuance. Please provide written comments on the draft permit no later than July 16, 2011. If you have any questions, please contact me at (919) 807- 6386 or jackie.nowell@ncdenr.gov. R ectfully, A. Jac lyn M.

The plant has completed an expansion and upgrade from 0.3 MGD to 0.6 MGD. The facility discharges to Naked Creek, which is classified as a C+ waters in the New River Basin. Because of the supplemental "+" symbol on the classification, Naked Creek is subject to a special management strategy in 15A NCAC 2B .0225, the Outstanding Resource Waters (ORW) rule to protect the downstream waters South Fork New and New Rivers designated ORW area. The stream is listed on the 2010 North Carolina impaired stream 303(d) list for degraded ecological/biological integrity within the fish community. The permit will continue to require the City to implement its pretreatment program. Jefferson has a pretreatment program with a short term monitoring plan, because it has a permitted flow of less than 2 MGD and/or less than four (4) significant industrial users (SICs). Significant industrial users include American Emergency Vehicles and Gates Rubber Company. REASONABLE POTENTIAL ANALYSIS: The following parameters are monitored through the existing permit: Cd, CN, Cu, Pb, Zn, Hg, Ag. The following parameters are monitored through the modified pretreatment program with short term monitoring program (STMP): As, Cd, Cr, Cu, CN, Pb, Hg, Mo, Ni, Se, Zn, Ag. In the STMP, 4 samples are taken in one year, then none for the next four years, then repeat. \PC)E'l \( 0021709 Rn)e',v td P i2 c l Data submitted in discharge monitoring reports and PPAs from 2009 through 2010 were evaluated and a reasonable potential analysis (RPA) was done to determine whether effluent limitations or monitoring should be included in this permit renewal. Because of the C+ classification and the strategy to protect the ORW area downstream, one half the NC standard was used to develop the allowable concentrations for all metals except for mercury. For mercury, because of the statewide mercury impairment, the EPA recommended procedure of allowing no dilution for development of Hg limits was maintained, and therefore the NC standard of 12 ng/1 was applied, instead of halving the Hg standard to 6 ng/l. The RPA and effluent data is attached to the factsheet and the results are summarized below: o Monthly average and daily maximum limits for cadmium, cyanide and lead will be recommended based on the results of the reasonable potential analyses. The analyses indicated the reasonable potential for these parameters to exceed the North Carolina water quality standard in the receiving stream. These parameters will be limited and monitored monthly in accordance with DWQ guidance. o The daily maximum limit for mercury will be dropped from the permit based on the results of the reasonable potential analysis. However, quarterly monitoring for mercury will remain in the permit, based on the evaluation of the submitted data. o Silver monitoring will be dropped from the permit. There was no reasonable potential shown to exceed the water quality action level standard instream. All submitted silver data was below the laboratory detection level. Division guidance recommends that silver monitoring be continued in the pretreatment monitoring plan. o Copper and zinc monitoring will remain in the permit based on the results of the reasonable potential analyses. There was reasonable potential shown to exceed the water quality action level standard instream. These parameters will be monitored quarterly in conjunction with the whole effluent toxicity test. TOXICITY TESTING: Type of Toxicity Test: Chronic Ceriodaphnia Pass/Fail (Quarterly) Existing Limit: 001: Chronic P/F @ 30% Recommended Limit: 001: Chronic P/F @ 30% Monitoring Schedule: February, May, August, and November The facility has consistently passed its WET tests during this permit cycle. Since February 2007, the quarterly test has been passed 17 times, with two invalid tests in 2009. It is recommended that the chronic pass/fail test be renewed in this permit. COMPLIANCE SUMMARY: While overall compliance appeared to be good, the Jefferson WWTP did have violations of the lead limit in 2006, 2007 and 2009. DWQ actions included enforcement cases and notices of violation because of these violations. Past compliance evaluations of the facility have found the plant to be compliant with no major problems, reported. ;"Ip. 2 EWFV INSTREAM MONITORING: Upstream: 50 feet upstream Downstream: 250 feet downstream Parameters: Temperature and dissolved oxygen Reviewed instream data from 2008-2010 for the months of June through September. The review indicated that there were no DO stream standard violations downstream of the discharge for the past 3 years. Monthly downstream DO values ranged from 7.8 mg/1 to 9.6 mg/l. Recommend continuation of instream monitoring for temperature and dissolved oxygen. PROPOSED CHANGES: • Silver monitoring deleted because of RPA results and will continue to be monitored in STMP. • Mercury limit deleted because of RPA results, however quarterly monitoring will remain in the permit. • Monitoring for copper and zinc will be modified from 2/monthly to quarterly based on the results of the RPA and DWQ guidance for metals monitoring. • Limits for cadmium, lead, and cyanide will be in the permit and the monitoring frequency will be monthly based on the results of the RPA which indicated potential to exceed the NC standard instream and DWQ guidance for metals monitoring.

We successfully achieve a three part goal in managing our water resources facilities: 1) To surpass all North Carolina and Federal government clean water standards 2) To operate in the most cost-effective manner possible for our customers 3) To protect and enhance the public health of the New River Basin COLLECTION SYSTEM PERFORMANCE is critical to our river basin. We maintain about 18 miles of sanitary sewer lines and four pump stations. For the calendar year 2010 the Town of Jefferson experienced no sanitary sewer overflows. Our crews continue to locate and eliminate sources of groundwater inflow into the collection system through the use of closed circuit TV cameras placed in the lines, and smoke testing of specific areas in the system. Pump stations are monitored daily. In 2010 the Town worked in conjunction with the High Country Council of Governments to create a GIS map of the entire collection system, assigning GPS coordinates to all 450 manholes and pump stations in the system. WASTEWATER PLANT PERFORMANCE for 2010 has again been excellent. An average of 0.360 mgd was treated at the WWTP in 2010, which is about 60% of design capacity. This facility discharges into a section of the New River having a designation of Outstanding Resource Waters. As a result our discharge permit contains limits much lower than most other facilities in North Carolina. The tables below reveal our effluent quality to be well within these strict standards.

Sullins Governor Director February 24, 2011 Mr. Tim Church Water Resources Director P.O. Box 67 Jefferson, NC 28640 SUBJECT: Compliance Evaluation Inspection Town of Jefferson WWTP NPDES Permit # NCO021709 Ashe County Dear Mr. Church: Dee Freeman Secretary A Compliance Evaluation Inspection was performed on the Grade III facility by George Smith on February 22, 2011. Mr. Tim Church, ORC, Grade IV along with Mr. Fred Walters, Back-up ORC, Grade II were present for the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. Permit Your new NPDES permit became effective May 1, 2006 and expires March 31, 2011. A copy was kept on file. Records & Reports The facility performs and documents process control of the following: microscopic examination, settleability, MLSS, pH (clarifier, oxidation ditch, and digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and blanket height with a sludge judge. These records were in excellent order. The Performance Annual Report for the calendar year 2010 will be compiled and sent in the next few weeks. Facility Site Review There are four influent pumps (two-300gpm and two-400gpm). There was not a grit chamber installed before the barscreen. Although this .is not a requirement, there may be grit that accumulated before the barscreen, which may cause blockage and/or barscreen failure. This was noted during the previous inspection. The 3/8-inch automatic bar screen was properly operating. There is a leaking seal on a drive motor. The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor. The three rings of the ditch have sufficient dissolved oxygen. This treatment unit is performing very well.

The effluent over the weirs was clear. Both units were functioning very well, and were well maintained. The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was crystal clear. The chlorine contact chamber contained a clear effluent with no solids present. Flow Measurement The flow is measured with a 90' V-notch sharp crested weir. A Chessel type flow recording device is used with a seven day circular chart. The calibration was performed and documented by the Town of Jefferson on September 28, 2010. Laboratory The municipal lab is field certified #5206, and performed the following: Residual chlorine, dissolved oxygen, pH, residue settleable, and temperature. The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using the flow thru cell. A five point calibration is performed annually. The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer. A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NBS. Effluent/Receiving Waters The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor. Operations & Maintenance The Grade III facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters, Back- up ORC, Grade U. All treatment units in the facility were well maintained. The oxidation ditch is maintained at a MLSS of 2500 mg/L. Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite is used for dechlorination. Self -Monitoring Program The effluent is sampled by composite flow proportion method at 150 ml/10,000 gallons using Isco model 3710 FR samplers with refrigerator. They are well maintained, clean tubing and temperature is < 4°C. IFCompliance Evaluation Inspection February 24,2011 Page 3 of 3 All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters. A review of the monthly self -monitoring reports from January 2010 through December 2010 showed no monitoring or limit violations. Sludge Disposal The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with plenty of room for wasting solids. The sludge dryer appears to be well maintained. The facility generates approximately 50% Class A and 50% Class B residuals. The compliance inspection is considered satisfactory.

The headworks includes a manual screen as well to accommodate a by-pass of the unit in the event of repairs. Four influent pumps are located in the basement of the process building and are controlled by a float system in the wet well. Influent is pumped to the Oxidation Ditch where about 60 % of the flow enters the outside ring of the ditch and the remaining flow goes to the second ring. The oxidation ditch has two sets of rotors in each ring. One rotor operates continuously in each ring and the two are manually rotated as necessary to avoid excessive wear. Adjustment of flow and aeration to the first ring results in conditions that enhance nutrient removal. From the Oxidation ditch, flow enters the splitter box through which it may be directed and rate controlled to each clarifyer. A third compartment exists to accommodate a third clarifyer in the future. It is at this point where samples are taken for measuring settleability and MLSS. Two circular clarifyers operate in a parallel design. Return sludge from each enters the pump station located between clarifyer # 1 and the circular digester. The pump station is valved to allow RAS to flow back to the Oxidation Ditch or it may be wasted to the twin sludge basins or the circular digester. After leaving the clarifyers, flow enters the dual tertiary filters, operating in parallel sequence. Backwash water from the filters flows by gravity back to the influent wet well. Disinfection is accomplished using chlorine gas fed to the front end of the chlorine contact chamber. This unit has around the end baffling for maximum contact time. At the end of the chlorine contact chamber a sodium thiosulfate solution is fed as a dechlorinating agent. This area also features a post aeration basin just prior to the outfall to the receiving stream. (Also attached to this narrative is the "Sludge Management Plan which should be helpful in interpreting the flow diagram) Town of Jefferson Water Resources Sludge Manazement Plan for Jefferson WWTP I.

Sludge Transfer through the Facility Sludge collected from the two clarifyers enters a pump station. Wasting is accomplished by diverting return activated sludge flow to the dual sludge storage basins. When the basins are filled, the aerators are turned off and the solids settle, allowing clear supernatant to be decanted using telescopic valves in each basin. The supernatant flows by gravity to the influent headworks of the WWTP At the completion of the dewatering procedure aeration is resumed and the thickened sludge is transferred to the round digester using a submersible pump located in each basin. The round digester has the same dewatering capability. Upon dewatering the round digester, thickened sludge is transferred by gravity flow to the loading station. Supernatant from the round digester enters the sludge pump station where it is transferred to the oxidation ditch. The thickened sludge from the round digester is transferred by gravity to the truck loading station for disposal to land application sites or to the belt press and sludge dryer. This plan allows a 2% total solids value for the sludge and results in a maximum detention time. M. Class B Liquid Sludge Permit WQ 0004166 regulates Class B liquid sludge disposal. Jefferson has forty two acres permitted for liquid sludge disposal. All the acreage is located within a two mile radius of the WWTP. The facility uses a military style ten wheel drive truck fitted with a tank capacity of 1800 gallons. Sludge leaves the tank through a spreader bar six feet in length, controlled by a pneumatic valve operated from the cab of the truck. Procedures to Significantly Reduce Pathogens is demonstrated by analysis of seven annual sludge samples for coliform bacteria, having a geometric mean < 2,000,000 WN. Vector Attraction Reduction is demonstrated by volatile solids analysis of sludge in a thirty day bench scale shown to produce <15% volatile solids reduction. IV. Class A Dry Sludge Permit WQ 0022155 regulates Class A dry sludge production. This facility operates a Phoenix belt press with a capacity of 35 gpm. The cake from the belt press is augered to a Fenton sludge dryer. This unit generates a granular product with total solids > 90% and coliform bacteria are eliminated. This sludge is distributed on hay fields using an "eezee flow" drop spreader. (see the back of this page for details regarding Class A compliance under the 503 rules) Fenton Environmental Technologies, Inc. RIB Series Municipal Biosolids Dehydrator, 1(800) 777-1371 Class A Compliance Under the 503 Rules The SludgeMASTER RK series automatic batch style biosolids dehydrator is uniquely suited to insure compliance with the 40 CFR 503 regulations pertaining to achieving Class "A" biosolids. The RK dehydration chamber is loaded automatically with a predetermined amount of dewatered biosolids which starts the batch cycle. The total sludge load is subjected to a minimum temperature of 212 degrees F for a minimum of two and one-half hours which exceeds the time and temperature requirements of the 503 regulations pertaining to pathogen reduction. This complianch is shown as follows using Regime A under Alternative 1 which requires that solids be heated at 50 degrees C or higher for 20 minutes or longer. Time (in days) = 131,700,000 10^ 0.14 (temperature) Q 2 for the RK dehydrator at 212 degrees F (=100 C) Time= 131,700.000 or Time=131,700,000 or Time = less than 1.3/10^6 day. 10^ 0.14(100) 10^14 The time required in the RK for pathogen reduction would be less than 1 minute. Therefore, the minimum time requirement of 20 minutes specified in the 503 Rules must be followed. Following the 20-minute requirement, the RK dehydrator exceeds the time requirement by about 700%. Total cycle time is determined by achieving the desired sludge dryness. We normally recommend a minimum of 90 % dry solids for a finished product to qualify under 503.33 "Option-8" regarding vector attraction reduction. (Fully digested sludges need be dried to 75%- 503.33 "Option 7".) The SludgeMASTER RK patented process automatically adjusts the time and temperature regime foi the varying incoming wet sludge solids content. This feature is very important since dewatering operations will vary from time to time in solids consistency yet we must maintain consistent Class A biosolids at all times. Convelrsely, automatic flow through systems cannot adjust to varying conditions without disrupting their normal operation and compromising the finished Product Class "A" parameters. Please refer to 40 CFR 503.32 Pathogens - (a) (3) (ii) (9) for pathogen reduction requirements and to 40 CFR 503.33 (b) (7) and (8) for vector attraction reduction requirements. Fenton Environmental Technologies, Inc. guarantees Class A compliance on a continued basis with each SludgeMASTER RK Dehydration System In choosing Class A biosolids thermal dehydration jtilizing SludgeMASTER RK technology, your utility will be assured of an environmentally correct sludge handling solution fbr many years in the fixture.

Most sanitary sewer backups occur between your home and the town's sewer main? You can help prevent a costly and unsanitary overflow by following afew simple steps: K 0 C% Scrape excess grease in a container and dispose of it in the garbage. Place food scraps in waste containers or garbage bags for disposal with solid wastes, or start a compost pile; promote use of scraping ware prior to washing. "Place a wastebasket in the bathroom to dispose of solid wastes. Disposable diapers, condoms, and personal hygiene products do not belong in the sewer system. Promote the concept of I R's": Reduce, Reuse, Recycle. �i Pour grease, fats, and oils from cooking down the drain. Use the toilet as a wastebasket. 61 Use the sewer as a means of disposing food scraps. The Grease Goblin and associated materials are provided by the N.C.

Box 67 Jefferson, NC 28640 (336) " This is the Performance Annual Report for the Town of Jefferson Wastewater Treatment Plant and its outlying collection system, Permit # WQCS00220. Our goal is to continuously manage each of our water qualityfacilities in a manner that exceeds all state and federal standards, is cost effective for our consumers, and also protects and enhances the surface waters of the New River Basin. This report covers the calendar year 2009. Collection System Performance is critical to our river basin. We maintain about 18 miles of sanitary sewer lines and four pump stations. For the calendar year 2009 the Town of Jefferson experienced no sanitary sewer overflows. The Water Resources staff continues to implement plans to locate and eliminate sources of groundwater inflow and infiltration from our system. A number of manholes have been specifically identified for rehabilitation that will take place prior to the end of this fiscal year. The scope of this work will include pressure cleaning the interior of each manhole and applying a '/z inch coat of epoxy to produce a water tight seal over the entire structure. This practice will continue to be funded annually until all manholes in question have been repaired. Smoke testing of sewer lines is also an ongoing practice that is proving effective in locating areas in need of repair. In 2009 the town purchased a camera inspection unit capable of traveling within sewer lines and videoing the interior condition of the pipe. A GIS map is being created, assigning a GPS coordinate to every manhole and pump station in the collection system. Wastewater Plant Performance for 2009 has again been excellent. We treat an average flow of 0.320 mgd which is about 60 % of our design capacity. Our facility discharges into a section of the New River having a designation of Outstanding Resource Waters. As a result, the pollutant limits we are required to meet are lower than those of most other facilities in North Carolina. The chart below reveals our effluent quality to be well within these standards.

Mr. Tim Church, ORC, Grade IV along with Mr. Fred Walters, Back-up ORC, Grade II were present for the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. Permit Your new NPDES permit became effective May 1, 2006 and expires March 31, 2011. A copy was kept on file. Records & Reports The facility performs and documents process control of the following: microscopic examination, settleability, MLSS, pH (clarifier, oxidation ditch, digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and blanket height with a sludge judge. These records were in excellent order. This office received a copy of the Performance Annual Report for the calendar year 2008. Facility Site Review There are four influent pumps (two-300gpm and two-400gpm). There was not a grit chamber installed before the barscreen. Although this is not a requirement, there may be grit that accumulated before the barscreen, which may cause blockage and/or barscreen failure. This was noted during the previous inspection. The 3/8-inch automatic bar screen was properly operating. There is a leaking seal on a drive motor. The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor. The three rings of the ditch have sufficient dissolved oxygen. This treatment unit is performing very well.

The effluent over the weirs was clear. Both units were functioning very well, and were well maintained. The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was crystal clear. The chlorine contact chamber contained a clear effluent with no solids present. Flow Measurement The flow is measured with a 90' V-notch sharp crested weir. A Chessel type flow recording device is used with a seven day circular chart. The calibration was performed and documented by TC&M System Inc. on October 8, 2009. Laboratory The municipal lab is field certified #5206, and performed the following: Residual chlorine, dissolved oxygen, pH, residue settleable, and temperature. The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using the flow thru cell. A five point calibration is performed annually. The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer. A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NBS. Effluent/Receiving Waters The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor. Operations & Maintenance The Grade III facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters, Back- up ORC, Grade H. All treatment units in the facility were well maintained. The oxidation ditch is maintained at a MLSS of 2200 mg/L. Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite is used for dechlorination. Self -Monitoring Program The effluent is sampled by composite flow proportion method at 150 ml/10,000 gallons using Isco model 3710 FR samplers with refrigerator. They are well maintained, clean tubing and temperature is < 4°C. Compliance Evaluation Inspection November 25, 2009 Page 3 of 3 All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters. A review of the monthly self -monitoring reports from January 2009 through September 2009 did show: • One daily maximum violation for Lead during May 2009. • Two daily maximum violations for Lead during June 2009. Sludge Disposal The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with plenty of room for wasting solids. The sludge dryer appears to be well maintained. The facility generates approximately 50% Class A and 50% Class B residuals. The compliance inspection will be considered satisfactory.

Our goal is to continuously manage alto our water qualityfacilities in a manner that not only exceeds all state and federal standards, but also protects and enhances the surface waters of the New River basin. This report covers the calendar year 2008. Collection System Performance is critical to our river basin. We maintain about 18 miles of sanitary sewers and four pump stations. For the calendar year 2008 the Town of Jefferson experienced no sanitary sewer overflows. The Water Resources staff continues to implement plans to locate and eliminate sources of groundwater infiltration and inflow in our collection system. Efforts are now under way to repair 46 manholes identified as sources of infiltration. Smoke testing of collection lines is ongoing. This year a CCTV camera will be obtained that will allow interior inspection of sewer lines. Funding has been requested under the American Recovery and Reinvestment Act of 2009 to replace 8,500 feet of 18" vitreous clay sewer main. Wastewater Plant Performance for 2008 has again been excellent. The information listed below is a portion of the required compliance monitoring. Our facility discharges into a section of the New River designated as Outstanding Resources Waters. As a result, the pollutant limits we are required to meet are much lower than those of most other facilities.

Sullins, Director Division of Water Quality A Compliance Evaluation Inspection was performed on the Grade III facility by George Smith on November 20, 2008. Mr. Tim Church, ORC, Grade IV along with Mr. Fred Walters, Back-up ORC, Grade II were present for the inspection. Mr. Marc Stokes, Technical Assistance was present during the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. This inspection evaluated nine (9) areas. The respective rating for each area is noted in Section C of the attached EPA inspection report, and the observations during the inspection of each area are addressed below: Permit Your new NPDES permit became effective May 1, 2006 and expires March 31, 2011. A copy was kept on file. Records & Reports The facility performs and documents process control of the following: microscopic examination, settleability, MLSS, pH (clarifier, oxidation ditch, digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and blanket height with a sludge judge. These records were in excellent order. The Performance Annual Report for the calendar year 2007 sent to this office.

December 10, 2008 Page 2 of 4 Facility Site Review There are four influent pumps (two-300gpm and two-400gpm). There is one influent pump that is out of service, waiting for a $270 bolt. The brush motor on the mechanical bar screen was not working properly. The 3/8-inch automatic bar screen and compactor appeared to be properly operating. The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor. The three rings of the ditch have more than sufficient dissolved oxygen. This treatment unit is performing very well. The new secondary clarifier had some straggler flock coming over the weirs. The effluent over the weirs was clear. The unit was functioning very well, and were well maintained. The old secondary clarifier was out of service, waiting on a part. The unit was empty.. The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was crystal clear. The chlorine contact chamber contained a clear effluent with no solids present. Flow Measurement The flow is measured with a 90' V-notch sharp crested weir. There is a small leak around the weir plate, and the aluminum plate is bowed out. This will need to be addressed before the next inspection. A Chessel type flow recording device is used with a seven day circular chart. The calibration was performed and documented by TC&M System Inc. on March 27, 2008. Laboratory The municipal lab is field certified #5206, and performed the following: Residual chlorine, dissolved oxygen, pH, residue settleable, and temperature. Mr. Tim Church. December 10, 2008 Page 3 of 4 The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using the flow thru cell. A five -point calibration curve was performed on April 24, 2008. The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer. A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NBS. Effluent/Receiving Waters The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor. Operations & Maintenance The Grade III facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters, Back-up ORC, Grade II. All treatment units in the facility were well maintained. Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite, used for dechlorination. Self -Monitoring Program The influent and effluent is sampled by time composite method using Isco model 3710 FR samplers with refrigerator. They are well maintained, clean tubing and temperature is < VC. Flow proportional sampling is a permit requirement. The Isco sampler must be hooked to the effluent flow device and a the proper sampling must be performed per your NPDES permit Part!!, Section A, Composite Sample, (3). Failure to perform this is considered apermit violation. All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters. A review of the monthly self -monitoring reports from January 2008 through September 2008 did show two daily maximum violations for Lead during March 2007. Mr. Tim Church. December 10, 2008 Page 4 of 4 Sludge Disposal The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with plenty of room for wasting solids. The sludge dryer appears to be well maintained. The facility generates approximately 50% Class A and 50% Class B residuals. Please be advised, these violations and any future violations are subject to civil penalty assessment of up to $25,000.00 per day, per violation, as well as other actions by the Division of Water Quality. Please submit to this office, in writing, on or before December 30, 2008 when you will be sampling flow proportion as required per the permit. The compliance inspection will be considered satisfactory. If you have any questions please contact George Smith or me at (336) 771-5000. Sincerely, 4 Steve W.

Dept of ENR DEC 3 0 2008 W nstcn-Ss- This correspondence addresses the two areas of deficiency noted during the Compliance Evaluation Inspection conducted at the Town of Jefferson WWTP on November 20, 2008 by Mr. George Smith and Mr. Marc Stokes. The first item was listed under the heading of Flow Measurement and is in regard to a small leak in the epoxy seal around the aluminum 90 degree V-notch weir. This leak will be patched with an epoxy product that is also used for sealing the interiors of manholes. It is marketed as Epoxytec CPP and has a very high compressive strength able to cure in wet conditions. The second item is listed under Self-MonitoringProgram and addresses the permit requirement of flow proportional sampling. A cooperative effort between our sampler manufacturer (ISCO) and the service representative for our Eastech flowmeter (Eddie Wentz of TC&M) is currently underway to combine the proper cable set and pin connections to allow the two devices to be properly interfaced. This procedure may require one or two weeks to complete. I will notify Mr. Smith when this has been accomplished.

Our goal is to continuously manage all of our water qualityfacilities in a manner that not only exceeds all state and federal standards, but also protects and enhances the surface waters of the New River basin. This report covers the calendar year 2007. Collection System Performance is critical to our river basin. We maintain about 15 miles of sanitary sewers and four pump stations. On January 2, 2007an act of vandalism resulted in the blockage of a manhole in the sewer main. As a result, approximately 150,000 gallons of sewage flowed into Naked Creek. No fish kills or other adverse impacts resulted from this incident. This event was reported to the NC Division of Water Quality as a Sanitary Sewer Overflow. The Water Resources staff continues to implement plans to locate and eliminate sources of infiltration and inflow in our collection system. A large residence was found to have its roof drains connected to the sewer system. These gutters have subsequently been removed from the town's sewers. A number of faulty manholes have been selected for relining. Another round of smoke testing will also occur this summer to locate faulty collection lines and/or unauthorized connections. Our 2008 budget will also includes funds for the purchase of a CCTV camera capable of entering sewer lines and providing videos from the interior of collection lines. This technology allows crews to precisely identify and locate defective sections of sewer pipes. Wastewater Plant Performance for 2007 has again been excellent. The information listed below is a portion of the required compliance monitoring.

Tedder, Regional Supervisor NC Division of Water Quality 585 Waughtown Street Winston-Salem, NC 27107 SUBJECT: Response to Compliance Evaluation Inspection Town of Jefferson, NPDES NCO021709 Inflow and Infiltration Rehabilitation; Flow measurement Dear Mr. Tedder: As required by the Compliance Evaluation Inspection at the Jefferson WWTP performed on November 8, 2006 I am responding in regard to the efforts currently underway as well as future plans to remove inflow and infiltration from the Town's collection system. Collection system rehabilitation has been informally attempted sporadically in previous years, only to lose momentum due to other obligations. The town has begun to develop a systematic strategy aimed toward locating and eliminating sources of FI. Even prior to this CEI some elements of the plan were being carried out. Information is being gathered regarding the impact of specific rainfall events on our flow. Additionally, basic repairs that are within our ability have been made to selected manholes. Our aldermen have included a line item in the budget for collection system rehabilitation. On December 21" I will be making a presentation to the aldermen regarding the implementation of certain phases of this work. I have included a portion of that information in this correspondence. Our entire collection system has been mapped and overlaid onto an aerial photograph. On that map each manhole has been assigned an ID number. The diameter and pipe material of each segment of the collection system is listed. In the summer of 2005, staff personnel from the WWTP along with an engineer from McGill Associates, P.A. visited every manhole in the collection system that could reasonably be located. Out of approximately 450 manholes in the system, less than a dozen were unaccounted. During this inspection process an individual report was completed for each manhole in regard to location, depth, condition of inverts and grouting, seals between sections, steps and bench condition, along with other factors that might indicate evidence as an 1/1 source. Using this study, we have begun to prioritize these manholes based on potential liability for FI. The following is a list of some of the conditions we have discovered and corrected. jeffwns@fastransit.net Page 2 Sources of III Located * A large residence has its entire guttering system, including a separate garage, connected to the sanitary sewer. We photographed the results of our smoke testing and we are in the process of requiring the owner to correct this situation, citing Section 2.1 (b) [13] of the Sewer Use Ordinance. * A ductile iron sewer main lateral located in a creek bed had separated at a joint. Any rise in the level of the creek allowed that water to enter the collection system. This entire section of line was replaced and configured so that no joint would be present in the streambed. * In a housing development (Woodcroft) two manholes were identified having six inch dead-end service lines stubbed out of the manholes in order to serve potential contruction on adjoining vacant lots. These service lines extend well into the lots and have considerable flow in them during periods when the water table is high, indicating that these lines where not adequately capped, the line itself is broken, or both. Plugs will be placed into the inverts of these lines in the manhole while the property owner will be required to make repairs, also based upon Section 2.1 (b) [13] of the Sewer Use Ordinance. * Manhole number 332 on Oakgrove Circle had two lift -holes in the wall that had not been filled after installation. One of these open holes was observed during a wet weather event to be releasing a stream of water one inch in diameter, projecting it a distance of almost one foot out into the manhole, similar to a fountain. On November 15' personnel from the WWTP filled these lift -holes with hydraulic cement and a visit to this manhole during the following wet - weather event revealed that a water -tight seal had been achieved. * A number of manholes have been determined to have poorly grouted inverts or grout that is in the process of failing and/or lids and risers with structural defects, obvious sources of I/I. * Other precast manholes are showing evidence of sealant failure between sections and also at the seal where the base and first section join. A case in point is manhole number 373 on Luther Rd. It is a deep manhole with three precast sections. During a recent extremely high ground water period it was observed to contain leaks between the sections, giving the appearance of a shower within the manhole. *Smoke testing in previous years has indicated a number of private service lines that leak. We will be in the process of identifying those more precisely and requiring owners to make repairs. * The collection system has about 2.5 miles of vitrous clay pipe that serve as a main trunk installed as part of the original collection system and WWTP construction in 1967-68. We have no direct evidence of failure in this area but the presence of large diameter clay pipe that has been in place forty years calls for CCTV inspection as an early objective to be carried out. Page 3 UI Location Technologies Being Considered As you are aware, a wide selection of technologies are available for M location and collection system repair. Some of these products and techniques are being studied in order to determine those that are best suited to the conditions existing within our collection system. I plan on visiting jobsites to observe the implementation of these methods and discuss their effectiveness with other customers. While I am aware that you are not allowed to recommend specific suppliers, any suggestions that you and your staff might make in regard to general technologies for UI location and repair would be welcome. For the present, we are focusing on the following. Smoke testing We possess this equipment and have used it rather effectively. It is obviously a necessary tool in most any VI location project. Area -Velocity meters Flow measurement within the collection system has been implemented to a limited extent. Mr. Gene Johnston in the office of Construction Grants and Loans assisted us approximately three years ago with the installation of area -velocity meters at what we believed might be strategic points within the system. He retired prior to this project being completed and I am not aware if the data collected is still available. Even if it is available, we have in the meantime divided our collection system into mini -systems that would now yield much more accurate data than that collected previously. I recently called the Construction Grants and Loans office and explained this need and my desire to possibly borrow these area -velocity meters. I was referred to Mr. Dan Blaisdale's voice mail but I have not received any information regarding the availability of these meters. If your staff could look into that matter I would be most appreciative. Flow monitoring within the mini -systems we have recently established would be a productive tool in allowing us to select areas that qualify for CCTV inspection. If we could get access to the area -velocity meters I think the town would be willing to provide the lap top computer and software needed. Ongoing Manhole Inspections Despite its low -tech nature, there is not a better tool than on -site observations. Putting on the rain suits and opening manholes during storm events and shortly thereafter can reveal some valuable information. This practice will continue. Conductivity measurement This has not been implemented but consideration has been given to using a conductivity meter to monitor changes upstream and downstream of suspected UI points within sewer lines in order to detect variations in TDS in the wastestream. Page 4 Rehabilitation Technologies Being Considered Resin -epoxy sealant for manholes This appears to be a proven method for correcting some of our problematic manholes that have leaks around the inverts and precast seams. I am considering a product from the Raven Lining System. References indicate this product has aggressive bonding characteristics to underground infrastructures. I am hoping to acquire some general pricing for this method shortly and visit an application site. In -House maintenance As part of prioritizing manholes in need of repair, evaluation is also conducted on the basis of the structures that can be repaired with grouting, the use of hydraulic cement, and other more basic repairs that our staff can perform effectively. Several of our manholes will fall into this category. Pressurized grouting This method involves drilling through the manhole wall in the vicinity of leaks and injecting grout under pressure through the wall and outward around the exterior to seal the failing area. The use of the interior resin -epoxy sealant appears to be more effective but this product will continue to be under consideration. Heat fusion slip -lining of collection mains It is a fact that faulty manholes are contributing to I/I. It is just as certain that when portions of sewer lines are examined by the bright light of CCTV inspection they too will prove to be a source of UI. Rather than excavate the lines in need of repair, slip -lining (trenchless technology) will be implemented in these areas. Insituform is a widely known vendor for this product but the Town will also explore other similar suppliers. As mentioned earlier, this is a situation the Town has made some random attempts to correct in the past with moderate success, but a concerted effort has never taken hold. With a staff and budget that is typical in size for a small municipality it is easy (but not excusable) for collection system rehabilitation to take on a lower priority in the face of activities such as WWTP operation and maintenance, WTP operations, laboratory operations and certifications, biosolids handling, Industrial Pretreatment programs, pump station maintenance and all those unseen situations that are unavoidable. But this is a window of opportunity for the Town. We are fortunate to have a WWTP in which we can take pride. At present, approximately 40% of our capacity is still available and the plant's discharge is well within NPDES limits with no outside factors threatening it's ability to continue that status. There are no moratoriums or compliance orders facing us. Our leaders are aggressively budgeting for the correction of UI and we would certainly be interested in your suggestions regarding potential sources of funding that we might pursue to assist in this project. Personally I am excited about taking on this challenge and seeing the level of success we will achieve. It is likely to be a long term project. This situation is not Page 5 the result of a few large sources that we can locate and repair quickly and easily. It is more likely the result of a large number of small to moderate sources that will require time and patience to correct, as evidenced by the effect high water tables and not just precipitation alone exert upon the WWTP flow. However we have gathered sufficient information that will allow us to measure our progress as we go forward and cause patience and good judgment to be applied. In another matter, Mr Smith also indicated some concerns regarding the accuracy of the effluent flow chart and counter. Our staff has compared the chart reading with the actual head measured in the v-notch and could not detect any variation between the two readings. This was performed with the chart in a high flow position as well a low flow position with similar results. Mr Eddie Wentz of TC & M Systems in Kernersville, NC performed maintenance and flow calibration on the effluent ultrasonic meter in the summer of 2006. I am requesting a calibration certification statement from him. Should this document be unavailable, Mr. Wentz will return for an additional calibration. I hope this correspondence adequately addresses the issues and concerns resulting from our compliance evaluation inspection. Should additional information be required please give me a call at (336) 246-2165 or I can be reached by e-mail at ; effwns s fastransit. net. Thank for your assistance in helping the Town of Jefferson protect the waters of North Carolina and the New River Basin. Respectfully, _�-0441ok Tim Church Water Resources Director cc: Mr. George Smith, WSRO; *` Cathy Howell, town manager Town of Jefferson mayor and aldermen Enclosures F A Thief Among Us Approximate Total Cost of 2004 WWTP Expansion $ 3,800,000.00 Additional Capacity Resulting from this Project 3001000 gallons/day The cost of adding capacity to our wastewater treatment plant roughly amounted to $12.65 per gallon. Plant capacity is a valuable commodity that municipalities have learned to guard carefully. Inf low/Inf filtration is nothing more than a thief that robs us of capacity, threatening future customer base and jeopardizing compliance with NPDES limits as our plant normally reaches its design flow in future years. As we have witnessed, upgrading a WWTP to stay ahead of the curve can be expensive. Present conditions indicate a more efficient strategy is to locate and rehabilitate points within the collection system that are allowing rain, groundwater, and surface waters to enter. A collection system must be viewed as a valuable piece of capital equipment, much like a fleet of vehicles or a treatment plant that have predictable and routine schedules of maintenance and repair. Many towns have placed a lower priority on collection systems simply because they are out of sight and out of mind. Rehabilitation of sewer lines and manholes often, if not always, results in a greater benefit to the utility than the construction of new facilities, based on unit costs. Using the approximate construction costs referenced earlier, $500.00 spent on construction would yield about 40 gpd capacity. That same $500.00 spent in the rehabilitation of a single manhole could eliminate thousands of gallons/day of flow during rains or periods of high groundwater. F However, there are no guarantees in I/I removal projects. Some towns have spent a few thousand dollars and removed large amounts of I/I from their systems. Conversely, other projects have consumed several thousand dollars and produced only modest improvements. Careful preliminary planning and the development of a prudent strategy are critical in making these efforts as effective as possible. Some of the preliminary work such as system mapping and a manhole study have been completed. We have begun locating and prioritizing potential repair sites. Also, a few basic repairs have been made to some manholes. Attempts to begin this task have been made previously, only to lose momentum due to other obligations. The WWTP expansion has been a huge success. It is a facility in which the Town can take pride. With over 40% of capacity remaining available, we have a window of opportunity for collection system rehabilitation to begin in earnest, without the pressure of deadlines and moratoriums over our heads. Your decision to budget for collection system repair is wise. I encourage you to allow it to remain in future budgets. Hopefully by the Spring of 2007 sufficient planning will have been completed to allow us to select the best available rehabilitation technologies for our specif is needs and begin their implementation.
