The main objective of the Annual TMDL Report is to describe the BMPs implemented by the Town of Stallings to reduce non -point source pollutant loading to streams subject to an approved TMDL to the maximum extent practicable. 1.1 Background of Goose Creek Watershed On August 10, 2006, the Town of Stallings received written notification from the N.C. Division of Water Quality that it is subject to the approved fecal coliform TMDL for Goose Creek. The Town of Stallings (working cooperatively with Mecklenburg County Water Quality Program) subsequently completed a TMDL Water Quality Recovery Program Plan for the Goose Creek 'rMDL, which was submitted to the N.C. Division of Water Quality on July 9, 2008 for compliance with the above described permit requirement. Implementation of the Plan began in July 2008. Input received from the Advisory Group formed to facilitate the implementation of 2012 TMDL Annual TMDL Report STALL.INGS p Nllmilc. iW)LINq this Plan resulted in revisions that were subsequently submitted to the N.C. Division of Water Quality on November 13, 2009. Implementation of this Plan began in November 2009. The Town of Stallings has continued working cooperatively with Mecklenburg County Water Quality Program and the Towns of Mint Hill and Indian Trail to implement the requirements of this Program. During FY10-I 1, the North Carolina 2010 303d List was finalized. In this list, the Use Category for AU Number 13-17-18a (Goose Creek from source to SR 1524) was changed from 4t (standard violation) to 1 t (no criteria exceeded) for fecal coliform bacteria. Category It is described as "Parameter is supporting uses in the AU and there is an approved TMDL for the parameter". Subsequent to the release of the list a meeting was held with NC DENR staff and the decision was made to allow the suspension of the WQRP for areas of the watershed upstream of SR1524, which includes a portion of Stallings (Figure 1).

Figure I: Map Showing Goose Creek WQRP Status Seetion 2.0 BMPs in Goose Creek Watershed 2.1 Utility Crossings and Outfall Inspections During the reporting period, the Town of Stallings continued to implement the Town's Illicit Discharge Detection and Elimination program, which includes the identification of outfalls, visual inspection of utility crossings and evaluation of any dry weather flows. "These activities were conducted as part of stream walks. During FYI 2-13, no pollution issues were observed with utility crossings or outfall inspections. 2.2 Septic System Evaluations To help identify and eliminate possible sources of fecal coliform within the Goose Creek Watershed, the Town of Stallings identified and inspected residential sanitary septic systems (individual wastewater treatment systems) within the Goose Creek watershed in order to verify 2 0STAL.1Nfr'N�11�ol; S 2012 TMDL Annual TMDL Report NORH I CAROLINA that known systems were functioning as designed. Any systems identified as non -compliant, or in need of repair, have the potential to contribute untreated sanitary wastewater to surface waters, thereby increasing fecal coliform loading within the watershed. The Town of Stallings partnered with the Union County Health Department (the department with permitting authority over septic systems) to conduct inspections of all identified septic systems in the Goose Creek watershed. To date, 74 households within the Goose Creek watershed were identified that had active septic systems. Each of the identified properties was visited by an inspection team, but only 63 were actually inspected. Three (3) of the identified properties were vacant at the time of inspection. Because the properties were vacant, the septic systems were not in use at the time of the inspection. An adequate inspection of the system could not be conducted and the overall compliance status could not be verified. However, no surficial problems were reported at these locations that would indicate the likelihood of a previous or recent problem with the systems. Eight (8) additional properties with active septic systems were not inspected because the property owners would not allow the inspection teams to access to their property for the specified purpose of inspection. The remaining 63 properties within the Goose Creek Watershed that had active septic systems were inspected between June 26, 2012 and July 17, 2012. For each inspection conducted, a checklist form was completed by the inspection team which recorded the date, location and the condition of the system inspected. Additional notes were also recorded to capture any significant or unusual circumstances. Out of the 63 active septic systems inspected, there were a number of minor issues identified. These issues included three (3) malfunctioning alarms, two (2) structures erected within the designated drain fields, and four (4) miscellaneous issues ranging from a failing electrical switch to overgrown vegetation in the drain field. Each of these issues was addressed with the respective property owners and repairs were requested to correct the identified deficiencies. Only on (1) of the systems inspected had significant issues that warranted a Notice of Violation for non-compliance. The system had apparently malfunctioned at some time in the past and the property owners had taken measures to bypass the failed system. Efforts made by the property owners to bypass the system included illegal wiring, re-routing of house drains and the installation of a bypass pump. The property owner was issued a Notice of Violation. An example of the inspection form used to collect septic system information is included in Appendix A. The inspection data collected on these forms is summarized in Appendix B. 2.3 Stream Walks During FYI 2-13, The Town of Stallings walked one third (1/3`d) of all streams in the Goose Creek Watershed. The purpose of these walks was to identify and eliminate all pollution sources identified from storm water outfalls, creek crossings and infrastructure failures.

During the FY12-13 stream walks, the following activities were conducted within the Goose Creek Watershed: • A total of 3.5 miles of streams were walked; • A total of 28 storm water outfalls were inspected; • The entire storm drain system was inspected including inlets, pipe outlets, and manholes; • No potential pollution issues were identified; • No new infrastructure issues were identified. Section 3.0 BMPs in TMDL Watersheds Without WLAs For watersheds that have a TMDL without a specific WLA, the "Down of Stallings implemented tailored strategies to enhance water quality recovery. 3.1 Illicit Discharge Program During the reporting period, the Town of Stallings continued to implement the Town's Illicit Discharge Detection and Elimination program, which includes the identification of outfalls, visual inspection of utility crossings and evaluation of any dry weather flows. During FY 12-13, no pollution issues were observed with utility crossings or outfall inspections. 3.2 Stream Walks During FY12-13, The Town of Stallings performed stream walks in one-third (1/3`d) of the TMDL watersheds within the Town of Stallings. The purpose of these walks was to identify and eliminate all pollution sources identified from storm water outfalls, creek crossings and infrastructure failures. During the FY12-13 stream walks, the following activities were conducted within the TMDL Watersheds (excluding Goose Creek): • A total of 4.3 miles of streams were walked; • A total of 30 storm water outfalls were inspected; • The entire storm drain system was inspected including inlets, pipe outlets, and manholes; • No potential pollution issues were identified; • No new infrastructure issues were identified. The Town of Stallings will continue implementing stream walks as described in the Storm Water Management Program Plan within these TMDL watersheds. 4 IDS.I UN'h' Ul� •LA.L L.[.N C S 2012 TMDL Annual TMDL Report NORHICAROUNA Section 4.0 Summary of Future BMPs 4.1 Goose Creek Watershed During FYI2-13, the Town of Stallings continued to expand on efforts to reduce fecal coliform loading to Goose Creek. Specifically, these efforts include: • Continue to partner with Mecklenburg County and the Towns of Mint 1-1111 and Indian Trail to implement the Goose Creek WQRP. • Identify and inspect septic systems within the Goose Creek Watershed by partnering with the Union County Health Department in order to identify and correct deficiencies and failing systems. • Continue stream walks within the Town of Stallings (including Goose Creek) to identify and eliminate potential pollution sources. • The Town of Stallings post -construction ordinance will be implemented to continue focus of reducing turbidity and fecal coliform bacteria as primary pollutants of concern. Each of these BMPs will be re-evaluated annually for effectiveness at reducing fecal coliform loads to Goose Creek and re -initiated on a continuing basis as determined necessary. Based on the results from the FYI 2-13 activities, the Town of Stallings recommends continual implementation of the Goose Creek WQRP. The Town of Stallings recommends walking streams within the Town (including the Goose Creek Watershed) each fiscal year as necessary. The results of these BMPs will be included in future annual reports. 4.2 TMDL Watersheds Without WLAs "The "Town of Stallings will continue to implement enhanced strategies and measures within these watersheds including: • Enhancing Public Education efforts by targeting turbidity and fecal coliform as the main pollutants of concern. The "Down of Stallings post -construction ordinance will be implemented to continue the focus of reducing turbidity and fecal coliform bacteria through implementation of structural BMPs. In addition, Stallings post -construction ordinance requires additional storm water detention and peak control above that required by the state minimum standards which helps protect stream habitat by minimizing stream bank erosion caused by large volume flows. • Enhancing detection of illicit discharges by having staff continue performing stream walks to proactively look for illicit discharges and connections that can further degrade stream water quality and habitat. Gs InN'N [lF TAoS 2112 TMDL Annuai TMDL Report N01MI CAROLINA Continuing to actively inspect storm water infrastructure to identify possible issues within the system that could cause increased turbidity and degraded habitat. "These measures will be continually evaluated for effectiveness and will be adjusted as needed to reduce pollutants in these watersheds. 2 Example Septic System Inspection Form Inspection Date: Inspection Completed By: Site Parcel Id #: Site Address: GWS File #: Watershed: Catchment Id: Septic System Information: System Classification: ❑ II ❑ III ❑ IV ❑ V ❑ VI ❑a ❑b ❑c El El El ❑g System Description: (Ex: pump to 25% reduction) Year Operation Permit Issued: Land Records) System Age: Years ❑ Actual Inspection Information: (If no permit record is available use built date year from ❑ Estimated Comments Site accessible for inspection: ❑ Yes ❑ No Owner present: ❑ Yes ❑ No Drain field probed: ❑ Yes ❑ No System malfunction observed: ❑ Yes ❑ No Notice of Violation required: ❑ Yes ❑ No System located <200 ft. from ❑ Yes ❑ No surface water body: System located <50 ft. from ❑ Yes ❑ No stormwater BMP or diversion: Trees/vegetation in drain field: ❑ Yes ❑ No Irrigation on drain field: ❑ Yes ❑ No Well(s) located on property: ❑ Yes ❑ No General comments/observations: # photos taken: Dye Pack Left: ❑ Yes ❑ No Signature: Checklist: 1.

The main objective of the Annual 'TMDL Report is to describe the BMI's implemented by the Town of Stallings to reduce non -point source pollutant loading to streams subject to an approved TMDL to the maximum extent practicable. 1.1 Background of'Goose Creek Watershed On August 10, 2006, the 'Town of Stallings received written notification from the N.C. Division of Water Quality that it is subject to the approved fecal coliform TMDL for Goose Creek. The Town of Stallings (working cooperatively with Mecklenburg County Water Quality Program) subsequently completed a 'I-MDL Water Quality Recovery Program Plan for the Goose Creek TMDL, which was submitted to the N.C. Division of Water Quality on July 9, 2008 for compliance with the above described permit requirement. Implementation of the Plan began in July 2008. Input received from the Advisory Group formed to facilitate the implementation of ,.�... I OWN OF�" STALLINGs 2012 TIVIDL Annual TMDL Report this Plan resulted in revisions that were subsequently submitted to the N.C. Division of Water Quality on November 13, 2009. Implementation of this Plan began in November 2009. The Town of Stallings has continued working cooperatively with Mecklenburg County Water Quality Program and the Towns of Mint Hill and Indian "Frail to implement the requirements of this Program. During FY10-1 1, the North Carolina 2010 303d List was finalized. In this list, the Use Category for AU Number 13-17-18a (Goose Creek from source to SR 1524) was changed from 4t (standard violation) to It (no criteria exceeded) for fecal coliform bacteria. Category It is described as "Parameter is supporting uses in the AU and there is an approved TMDL for the parameter". Subsequent to the release of the list a meeting was held with NC DENR staff and the decision was made to allow the suspension of the WQRP for areas of the watershed upstream of SR1524, which includes a portion of Stallings (Figure 1).

These activities were conducted as part ofstream walks. During FYI 2-13, no pollution issues were observed with utility crossings or outfall inspections. 2.2 Septic System Evaluations To help identify and eliminate possible sources of fecal coliform within the Goose Creek Watershed, the Town of Stallings identified and inspected residential sanitary septic systems (individual wastewater treatment systems) within the Goose Creek watershed in order to verify 2 I!)N'N ill' 2012 't'MDL Annual TMDL Report TALLINGS n NoR'M CARMINR that known systems were functioning as designed. Any systems identified as non -compliant, or in need of repair, have the potential to contribute untreated sanitary wastewater to surface waters, thereby increasing fecal coliform loading within the watershed. The Town of Stallings partnered with the Union County Health Department (the department with permitting authority over septic systems) to conduct inspections of all identified septic systems in the Goose Creek watershed. To date, 74 households within the Goose Creek watershed were identified that had active septic systems. Each of the identified properties was visited by an inspection team, but only 63 were actually inspected. Three (3) of the identified properties were vacant at the time of inspection. Because the properties were vacant, the septic systems were not in use at the time ofthe inspection. An adequate inspection of the system could not be conducted and the overall compliance status could not be verified. However, no surficial problems were reported at these locations that would indicate the likelihood of a previous or recent problem with the systems. Eight (8) additional properties with active septic systems were not inspected because the property owners would not allow the inspection teams to access to their property for the specified purpose of inspection. The remaining 63 properties within the Goose Creek Watershed that had active septic systems were inspected between June 26, 2012 and July 17, 2012. For each inspection conducted, a checklist form was completed by the inspection team which recorded the date, location and the condition of the system inspected. Additional notes were also recorded to capture any significant or unusual circumstances. Out of the 63 active septic systems inspected, there were a number of minor issues identified. These issues included three (3) malfunctioning alarms, two (2) structures erected within the designated drain fields, and four (4) miscellaneous issues ranging from a failing electrical switch to overgrown vegetation in the drain field. Each of these issues was addressed with the respective property owners and repairs were requested to correct the identified deficiencies. Only on (1) of the systems inspected had significant issues that warranted a Notice of� Violation for non-compliance. The system had apparently malfunctioned at some time in the past and the property owners had taken measures to bypass the failed system. Efforts made by the property owners to bypass the system included illegal wiring, re-routing of house drains and the installation of a bypass pump. The property owner was issued a Notice of Violation. An example of the inspection form used to collect septic system information is included in Appendix A. The inspection data collected on these forms is summarized in Appendix B. 2.3 Stream Walks During FY12-13, The `town of Stallings walked one third (1/3"d) of all streams in the Goose Creek Watershed. The purpose of these walks was to identify and eliminate all pollution sources identified from storm water outfal Is, creek crossings and infrastructure failures. Fecal coliform 3 S(1'1N'N UI: TALL.INGS 2012 TMDL Annual'I'MDL Report NORHICARO UNA ... sampling was conducted in conjunction with stream walks only when it was necessary for the identification of fecal sources. During the FYI 2-13 stream walks, the following activities were conducted within the Goose Creek Watershed: • A total of3.5 miles of streams were walked; • A total of 28 storm water outfalls were inspected; • The entire storm drain system was inspected including inlets, pipe outlets, and manholes, • No potential pollution issues were identified; • No new infrastructure issues were identified. Section 3.0 BMPs in TMDL Watersheds Without WLAs For watersheds that have a TMDL without a specific WLA, the Town of Stallings implemented tailored strategies to enhance water duality recovery. 3.1 Illicit Discharge Program During the reporting period, the Town of Stallings continued to implement the Town's Illicit Discharge Detection and Elimination program, which includes the identification of outfalls, visual inspection of utility crossings and evaluation of any dry weather flows. During FY 12-13, no pollution issues were observed with utility crossings or outfall inspections. 3.2 Stream Walks During FY12-13, The Town of Stallings performed stream walks in one-third (1/3`d) of the TMDL watersheds within the Town of'Stallings. The purpose of these walks was to identify and eliminate all pollution sources identified From storm water outfalls, creek crossings and infrastructure failures. During the FY12-13 stream walks, the following activities were conducted within the TMDL Watersheds (excluding Goose Creek): • A total of 4.3 miles of streams were walked; • A total of 30 storm water outfalls were inspected; • The entire storm drain system was inspected including inlets, pipe outlets, and manholes; • No potential pollution issues were identified; • No new infrastructure issues were identified. The Town of Stallings will continue implementing stream walks as described in the Storm Water Management Program Plan within these TMDL watersheds. 4 1o"'N` l 2012 TMDL Annual TMDL Report STALLINGS NORM CAROLINn Section 4.0 Summary of Future BMN 4.1 Goose Creek Watershed During FY12-13, the Town of Stallings continued to expand on efforts to reduce fecal coliform loading to Goose Creek. Specifically, these efforts include: • Continue to partner with Mecklenburg County and the Towns of Mint Hill and Indian Trail to implement the Goose Creek WQRP. • Identify and inspect septic systems within the Goose Creek Watershed by partnering with the Union County Health Department in order to identify and correct deficiencies and failing systems. • Continue stream walks within the Town of Stallings (including Goose Creek) to identify and eliminate potential pollution sources. • The Town of Stallings post -construction ordinance will be implemented to continue focus of reducing turbidity and fecal coliform bacteria as primary pollutants of concern. Each of these BMPs will be re-evaluated annually for effectiveness at reducing fecal coliform loads to Goose Creek and re -initiated on a continuing basis as determined necessary. Based on the results from the FYI 2-13 activities, the Town of Stallings recommends continual implementation of the Goose Creek WQRP. The Town of Stallings recommends walking streams within the Town (including the Goose Creek Watershed) each fiscal year as necessary. The results of these BMPs will be included in future annual reports. 4.2 TMDL Watersheds Without WLAs The Town of Stallings will continue to implement enhanced strategies and measures within these watersheds including: Enhancing Public Education efforts by targeting turbidity and fecal coliform as the main pollutants of concern. • The Town of Stallings post -construction ordinance will be implemented to continue the focus of reducing turbidity and fecal coliform bacteria through implementation of structural BMPs. In addition, Stallings post -construction ordinance requires additional storm water detention and peak control above that required by the state minimum standards which helps protect stream habitat by minimizing stream bank erosion caused by large volume flows. • Enhancing detection of illicit discharges by having staffcontinue performing stream walks to proactively look for illicit discharges and connections that can further degrade stream water quality and habitat. 5 I OWN of ' 2012 TIM, Annual TM Report STALLINCS • Continuing to actively inspect storm water infrastructure to identify possible issues within the system that could cause increased turbidity and degraded habitat. These measures will be continually evaluated for effectiveness and will be adjusted as needed to reduce pollutants in these watersheds. 6 Example Septic System Inspection Form Inspection Date: Inspection Completed By: Site Parcel Id #: Site Address: GWS File #: Watershed: Catchment Id: Septic System Information: System Classification: ❑ II ❑ III ❑a El System Description: ❑ IV ❑ V ❑ VI El El ❑e ❑f ❑g (Ex: pump to 25% reduction) Year Operation Permit Issued: (If no permit record is available use built date year from Land Records) System Age: Years ❑ Actual ❑ Estimated Inspection Information: Comments Site accessible for inspection: ❑ Yes ❑ No Owner present: ❑ Yes ❑ No Drain field probed: ❑ Yes ❑ No System malfunction observed: ❑ Yes ❑ No Notice of Violation required: ❑ Yes ❑ No System located <200 ft. from ❑ Yes ❑ No surface water body: System located <50 ft. from ❑ Yes ❑ No stormwater BMP or diversion: Trees/vegetation in drain field: ❑ Yes ❑ No Irrigation on drain field: ❑ Yes ❑ No Well(s) located on property: ❑ Yes ❑ No General comments/observations: # photos taken: Dye Pack Left: ❑ Yes ❑ No Signature: Checklist: 1.

The main objective ofthe Annual TMDL Report is to describe the BMPs implemented by the Town of Stallings to reduce non -point source pollutant loading to streams subject to an approved TMDL to the maximum extent practicable. 1.1 Background of Goose Creek Watershed On August 10, 2006, the Town of'Stallings received written notification from the N.C. Division of Water Quality that it is subject to the approved fecal coliform TMDL for Goose Creek. The Town of Stallings (working cooperatively with Mecklenburg County Water Quality Program) subsequently completed a TMDI., Water Quality Recovery Program Plan for the Goose Creek TMDL, which was submitted to the N.C. Division of Water Quality on July 9, 2008 for compliance with the above described permit requirement. Implementation of the Plan began in July 2008. Input received from the Advisory Group formed to facilitate the implementation of ..: STOWN (01' TALLINGS 2012 Annual'i'Mi)L Report NORIIr ��AM ANA this Plan resulted in revisions that were subsequently submitted to the N.C. Division of Water Quality on November 13, 2009. Implementation ofthis Plan began in November 2009. The Town ol'Stallings has continued working cooperatively with Mecklenburg County Water Quality Program and the Towns of Mint Hill and Indian Trail to implement the requirements of tills Program. During FY10-11, the North Carolina 2010 303d List was finalized. In this list, the Use Category for AU Number 13-17-18a (Goose Creek from source to SR 1524) was changed from 4t (standard violation) to It (no criteria exceeded) for fecal coliform bacteria. Category It is described as "Parameter is supporting uses in the AU and there is an approved TMDL for the parameter". Subsequent to the release of the list a meeting was held with NC DENR staff and the decision was made to allow the suspension of the WQRP for areas of the watershed upstream of SR1524, which includes a portion of Stallings (Figure 1).

Any systems identified as non -compliant, or 061 ,. STALLINGS 2012 Annual'I'MI)l. Report V NORTH CAROLINA . in need of repair, have the potential to contribute untreated sanitary wastewater to surface waters, thereby increasing fecal coliform loading within the watershed. The Town of Stallings partnered with the Union County Flealth Department (the department with permitting authority over septic systems) to conduct inspections of -all identified septic systems in the Goose Creek watershed To date, 74 households within the Goose Creek watershed were identified that had active septic systems. Each of the identified properties was visited by an inspection team, but only 63 were actually inspected. Three (3) of the identified properties were vacant at the time of inspection. Because the properties were vacant, the septic systems were not in use at the time of the inspection. An adequate inspection of the system could not be conducted and the overall compliance status could not be verified. However, no surficial problems were reported at these locations that would indicate the likelihood of a previous or recent problem with the systems. Eight (8) additional properties with active septic systems were not inspected because the property owners would not allow the inspection teams to access to their property For the specified purpose of inspection. The remaining 63 properties within the Goose Creek Watershed that had active septic systems were inspected between June 26, 2012 and July 17, 2012. For each inspection conducted, a checklist form was completed by the inspection team which recorded the date, location and the condition of the system inspected. Additional notes were also recorded to capture any significant or unusual circumstances. Out of the 63 active septic systems inspected, there were a number of minor issues identified. These issues included three (3) malfunctioning alarms, two (2) structures erected within the designated drain fields, and four (4) miscellaneous issues ranging from a failing electrical switch to overgrown vegetation in the drain field. Each of these issues was addressed with the ' respective property owners and repairs were requested to correct the identified deficiencies. Only on (1) of the systems inspected had significant issues that warranted a Notice of Violation for non-compliance. The system had apparently malfunctioned at some time in the past and the property owners had taken measures to bypass the failed system. Efforts made by the property owners to bypass the system included illegal wiring, re-routing of house drains and the installation of a bypass pump. The property owner was issued a Notice of Violation. An example of the inspection form used to collect septic system information is included in Appendix A. The inspection data collected on these forms is summarized in Appendix 13. 2.3 Stream Walks During FY 1 1-12, The ']'own of' .Stallings began a program of walking all streams in the Goose Creek Watershed and within the 'Town of' Stallings. The purpose of these walks was to identify and eliminate ail pollution sources identified from storm water outfalls, creek crossings and infrastructure failures. Fecal coliform sampling was conducted in conjunction with stream walks only when it was necessary for the identification of fecal sources. 3 ••=••• STOWN Orr TALLINCS 2012 AnflUal'INDL Report N R n1 CAROLINA As a result of the stream walks, the following issues were reported: One illicit discharge was discovered and corrected; • Several dry weather flows were observed, evaluated, and found not to be illicit discharges; • Seventeen (17) storm water infrastructure issues (damaged pipes, sink holes, etc.) were identified that could cause excess sediment loading to Goose Creek and tributaries to Goose Creek. These issues were reported for follow-up and corrective action. A full copy of the Goose Creek TMDL Stream Walk report is included as Appendix C. Section 3.0 BMPs in TMDL Wtrtersheds Withottt WLAs For watersheds that have a TMDL without a specific WLA, the Town of Stallings implemented tailored strategies to enhance water quality recovery. 3.1 Illicit Dischame 1'ro ,r� am During; the reporting period, the Town of Stallings continued to implement the Town's Illicit Discharge Detection and Elimination program, which includes the identification oroutfalls, visual inspection of utility crossings and evaluation of any dry weather flows. 3.2 Stream Walks During; FYI 1-12, The Town of Stallings performed stream walks in the TMDL watersheds within the Town of'Stallings. The purpose of these walks was to identify and eliminate all pollution sources identified from storm water outfalls, creek crossings and infrastructure failures. The Town of Stallings will continue implementing stream walks as described in the Storm Water Management Program Plan within these TMDL watersheds. Section 4.0 Suninurry of Future BMP.ti 4.1 Goose Creek Watershed [hiring FYI 1-12, the Town of Stallings continued to expand on efforts to reduce fecal coliform loading; to Goose Creek. Specifically, these efforts included: 4 •'='�• f i rU'ti fif S TA L L I N C S 2012 Annual 'I'M DL Report • Continued partnering with Mecklenburg County and the "]'owns of Mint Hill and Indian "frail to implement the Goose Creek WQRP. • Identified and inspected septic systems within the Goose Creek Watershed by partnering with the Union County Health Department in order to identify and correct deficiencies and failing systems. • Walking streams within the Town of Stallings (including Goose Creek) to identify and eliminate potential pollution sources. • The Town of Stallings post -construction ordinance will be implemented to continue locus of reducing turbidity and fecal coliform bacteria as primary pollutants of concern. Each of tliese BMPs will be re-evaluated annually for effectiveness at reducing fecal coliform loads to Goose Creek and re -initiated on a continuing basis as determined necessary. Based on the results from the FYI 1-12 activities, the Town of Stallings recommends continual implementation of the Goose Creek WQRP. The "Town of Stallings recommends walking 1 /3 the length of streams within the Town (including the Goose Creek Watershed) each fiscal year. In this manner; each mile of streams within the town will be assessed every three years at a 1111n1n1Ui11. Tic Town of Stallings also recommends conducting follow-up septic system inspections within the Goose Creek Watershed on a 5-year cycle to ensure that existing systems are maintained and functioning properly. The results of these BMPs will be included in future annual reports. 4.2 TMDL, Watersheds Without WLAs The Town of Stallings will continue to implement enhanced strategies and measures within these watersheds including: Enhancing Public Education efforts by targeting turbidity and fecal coliform as the main Pollutants of concern. The Town of Stallings post -construction ordinance will be implemented to continue the focus of reducing turbidity and fecal coliform bacteria through implementation of structural BMPs. In addition, Stallings post -construction ordinance requires additional storm water detention and peak control above that required by the state minimum standards which helps protect stream habitat by minimizing stream bank erosion caused by large volume flows. Enhancing detection of illicit discharges by having staffcontinue performing stream walks to proactively look for illicit discharges and connections that can further degrade stream water quality and habitat. Continuing to actively inspect storm water infrastructure to identify possible issues within the system that could cause increased turbidity and degraded habitat. These measures will be continually evaluated for effectiveness and will be adjusted as needed to reduce pollutants in these watersheds. 5 Example Septic System Inspection Form Inspection Date: Inspection Completed By: Site Parcel Id #: Site Address: GWS File #: Watershed: Catchment Id: Septic System Information: System Classification: ❑ II ❑ III ❑ IV ❑ V ❑ VI El ❑b ❑c El ❑e El El System Description: (Ex: pump to 25% reduction) Year Operation Permit Issued: Land Records) (If no permit record is available use built date year from System Age: Years ❑ Actual ❑ Estimated Inspection Information: Comments Site accessible for inspection: ❑ Yes Owner present: ❑ Yes Drain field probed: ❑ Yes System malfunction observed: ❑ Yes Notice of Violation required: ❑ Yes System located <200 ft. from ❑ Yes surface water body: System located <SO ft. from ❑ Yes stormwater BMP or diversion: Trees/vegetation in drain field: ❑ Yes Irrigation on drain field: ❑ Yes Well(s) located on property: ❑ Yes General comments/observations: # photos taken: Checklist: ❑ No ❑ No ❑ No ❑ No ❑ No ❑ No ❑ No ❑ No ❑ No ❑ No Dye Pack Left: ❑ Yes ❑ No Signature: 1.

Stream Walk Report NORnICAROLIVA 1.0 Introduction From November 9, 2011 to February 1, 2012, Don Ceccarelli, P.L. and Jeff Price walked approximately 9.0 stream miles within the town limits of. Stallings, during baseilow cpnditions. The stream miles walked were all located in the Goose Creek watershed downstream of Stevens Mill Road as shown on the Union County GIS stream coverage. The subject area was bounded on the west by 1-485 and on the east by Mill Grove Road. The mileage walked Was bounded to the north and the south by the town boundary, but included streams that drained the Lmerald Lake Country Club Golf Course and a small portion ol'the Steven's Mill Subdivision. 2.0 Purpose The stream walks were primarily performed to liiltill the requirements of'the Goose Creek Water Quality Recovery Plan for locating; and reducing the fecal coliform loading in the Goose Creek Watershed as required by the Goose Creek `total Maximum Daily Load (TMDL) for fecal coliform. In addition, these stream walks fulfill other elements ol'the'lown of Stallings Storm Water Management Program Plan required by the Town's Phase II NPDLS permit (Permit # NCS000395) such as: • Updating; storm water outfall maps, • Maintenance of'storm water conveyance systems, • Detection of'dry weather flows, and • Detection and elimination of illicit discharges and connections, Stream walks serve not only to meet permit conditions, but more importantly help the Town of' Stallings reduce polluted run-off from entering streams. 3.0 Methodology Stream walks were conducted during baseilow conditions. For the purposes ol� this report, basellow conditions are defined as less than 0.10 inches of�precipitation occurring in a 24-11our day during; the previous 72-hour period. The last observed rainfall event prior to the November 9, 2011 stream walk occurred from November 3-4, 2011, at which time 1.00 inch of�rainfall was recorded. The next rainfall event occurred on November 10, 201 I, however only 0.03 inches of rainfall were recorded. All precipitation data reported here was taken from the United States Geological Survey (USGS) real -tinge network website; raingage 4350857080383245, CIZN-67 "Thompson Rd. Mint 1-I111, NC. "Phis appears to be the closest active USGS raingage to the project area. During; the stream walks, staff looked for dry weather flows, discoloration, sewer fungus, suspended solids, oily sheen, dead organisms in or around the stream and other indicators typically associated with pollution discharges. ']'his included any odors typically associated with 'I�)H'� CAI° "0 STALLI NCS �`Oose Greek TMDL Stream Walk Report _...: VUR'I II (AROLINA ..:...-. ... ..... . . -- - - - .. - sewage, petroleum or chemical pollution. Any unusual or atypical conditions were traced upstream to identify potential sources, and the sources were noted if identified. During the stream walks, each component ofthe storm water infrastructure (feature) encountered was geo-located, inspected and photographed. Geographic locations were determined using a Geographic Positioning System (GPS) enabled camera (Cannon Powershot SX230 I -IS) where possible. When no GPS was available, features were located using traditional mapping techniques and coordinates were determined from Google Maps. For each feature encountered, the following information was collected: feature ID (assigned), Latitude/Longitude (decimal degrees), feature type (ditch, culvert, pipe, tributary), feature material (earthen, corrugated plastic, corrugated metal, concrete, RCP, PVC, black iron), diameter (inches), shape (circular, channel, flared), dry weather Clow present (yes; no}, outfall condition (good, lair, poor); stream bank location facing downstream (right, left), suspected source and any comments. 4.0 Summary of Findings 4.1 _Illicit Discharges One l-eature was identified as a suspected leaking sewer aerial (Item 9 orl Table 1), and one illicit discharge (discharge of used oil and gollycourse chemicals) was identified at Lmcrald Lake Country Club Golf Course (Item 26 on "fable 1). Both ofthese were reported to the "Town of Stallings for follow-up investigation and resolution in accordance with the Town of Stallings Illicit Discharge Detection and I-limination program. 4.2 Storm Water Infrastructure Mar)mnu There were 168 features inspected and cataloged; including one sewer line aerial (black iron pipe), 58 culverts, 40 ditches, 65 pipes, three pond weirs, and one tributary. Dry weather flows were present at 24 features during the stream walk. Each of these dry weather flows was evaluated and/or traced to a source. Based upon the evaluation, none of the dry weather flows were from suspected pollution sources. The location of the storm water infrastructure is shown on Figure 1. 4.3 Storm Water Conveyance System Inspection During the stream walking activities, there were several potential infrastructure issues identified with the storm water conveyance system: • three corroded or damaged storm water pipes, • six pipes with partial blockage due to sediment or debris, • one cracked concrete headwall, • one sewer lateral acting as a debris dam, • one exposed sewer lateral due to erosion, • three pipe joint separations,and • two areas where sink holes were forming near storm drain pipes These storm water infrastructure issues were reported to the Town of Stallings maintenance stall for prioritization and follow-up.

"Table I below shows the applicable stream segments as listed in the 2012 North Carolina 303(d) Integrated Report. Table 1: TMDL Stream Segments Within the Town of Stallings Receiving Stream TMDL Reason Use Integrated Waste Load Stream Name Segment Parameter for Rating Category Report Allocations (Assessment Category Assigned Unit) Goose Creek 13-17-18a Fecal No criteria Recreation 1(t) Yes coliform exceeded Goose Creek 13-17-18b Fecal Standard Recreation 4(t) Yes coliform Violation North Fork 13-17-20-1 Turbidity Standard Aquatic 5 No Crooked Creek Violation Life South Fork 13-17-20-2a Fish Fair/Poor Aquatic 5 No Crooked Creek Community Rating Life /Benthos Notes: I (t) - Parameter is supporting uses in the AU and there is an approved TM Df, for the parameter 4(t) - Parameter assessment is impaired and there is an approved TMDL, for the parameter 5 - Waters for which TMDLs are required Only those listed stream segments that are contained within the jurisdictional boundary of the Town of Stallings are included on Table 1 above. The main objective of the Annual "TMDL Report is to describe the BMPs implemented by the Town of Stallings to reduce non -point source pollutant loading to streams subject to all approved TMDL to the maximum extent practicable. 1.1 Background of Goose Creek Watershed On August 10, 2006, the Town of Stallings received written notification from the N.C. Division of Water Quality that it is subject to the approved fecal cohlorni TMDL, for Goose Creek. The Town of Stallings (working cooperatively with Mecklenburg County Water Quality Program) subsequently completed a TMDL Water Quality Recovery Program Plan for the Goose Creek TMDL, which was submitted to the N.C. Division of' Water Quality on July 9, 2008 for compliance with the above described permit requirement. Implementation of the Plan began in July 2008. Input received from the Advisory Group formed to facilitate the implementation of "'=''• I( MIN Or�...: STA r NGS 2012 Annual "1'MD], Report this Plan resulted in revisions that were subsequently submitted to the N.C. Division of Water Quality on November 13, 2009. Implementation of this Plan began In November 2009. The 'Town of Stallings has continued working cooperatively with Mecklenburg County Water Quality Program and the Towns of Mint Hill and Indian `frail to implement the requirements of this Program. During FYI 0-1 1, the North Carolina 2010 303d List was finalized. In this list, the Use Category for AU Number 13-17-18a (Goose Creek from Goose Creek Watershed Water Quality Recovery Program Status source to SR 1524) was changed From 4t (standard violation) to It (no criteria exceeded) for fecal coliform bacteria. Category It is described as "Parameter is supporting uses in the AU and there is an approved TMDL for the parameter". Subsequent to the release ol�the list a meeting was held with NC DENR staff and the decision was made to allow the suspension of the WQRP for areas of the watershed upstream of'SR1524, which includes it portion of Stallings (Figure 1). i- 0 05 Figure I: Map Showing Goose Creek WQRP Status Section 2.0 BMP.s in Goose Creek Watershed 2.1 Utility CrossinLs and Outfall Inspections Legend — V{QRF"Ia"p{... Y+CPP &...+. YWn Tr.. `� StaYnp. IM.M.AvpC0.nt. - M.e HiY © C YIYiN.hea During the reporting period, the "Town of Stallings continued to implement the Town's Illicit Discharge Detection and I-limination program, which includes the identification of outlalls, visual inspection of utility crossings and evaluation ofany dry weather flows. 2.2 ' Scptic System Evaluations To help identify and eliminate possible sources of fecal coliform within the Goose Creek Watershed, the Town of'Stallings identified and inspected residential sanitary septic systems (individual wastewater treatment systems) within the Goose Creek watershed in order to verify that known systems were functioning as designed. Any systems identified as non -compliant, or 2 �,,' ��x N[sS 2011 AnnkmI TMU Report TALLI .-": I l W 1 U r1 i:ARoJANA .. in need ofrepair, have the potential to contribute untreated sanitary wastewater to surface waters, thereby increasing fecal coliform loading within the watershed. The '[own of Stallings partnered with the Union County Health Department (the department with permitting; authority over septic systems) to conduct inspections of all identified septic systems in the Goose Creek watershed To date, 74 households within the Goose Creek watershed were identified that had active septic systems. L.ach ofthe identified properties was visited by an inspection team, but only 63 were actually inspected. Three (3) of the identified properties were vacant at the time of inspection. I3ecause the properties were vacant, the septic systems were not in use at the time of the inspection. An adequate inspection of the system could not be conducted and the overall compliance status could not be verified. However, no surficial problems were reported at these locations that would indicate the likelihood of�a previous or recent problem with the systems. Eight (8) additional properties with active septic systems were not inspected because the property owners would not allow the inspection teams to access to their property for the specified purpose of' inspection. The remaining 63 properties within the Goose Creek Watershed that had active septic systems were inspected between .tune 26, 2012 and July 17, 2012. For each inspection conducted, a checklist form was completed by the inspection team which recorded the date, location and the condition of the system inspected. Additional notes were also recorded to capture any significant or unusual circumstances. Out of the 63 active septic systems inspected, there were a number of minor issues identified. These issues included three (3) malfunctioning alarms, two (2) structures erected within the designated drain fields, and tour (4) miscellaneous issues ranging from a failing electrical switch to overgrown vegetation in the drain field. Mach of these issues was addressed with the respective properly owners and repairs were requested to correct the identified deficiencies. Only on (I) of the systems inspected had significant issues that warranted a Notice of Violation for non-compliance. The system had apparently malfunctioned at some time in the past and the property owners had taken measures to bypass the failed system. Efforts made by the properly owners to bypass the system included illegal wiring, re-routing of house drains and the installation of a bypass pump. The property owner was issued a Notice of Violation. An example of -the inspection form used to collect septic system information is included in Appendix A. The inspection data collected on these fonns is summarized in Appendix B. 2.3 Stream Walks During I' Y I 1-12, The Town of Stallings began a program of walking all streams in the Goose Creek Watershed and within the Town of'Stallings. The purpose of these walks was to identify and eliminate all pollution sources identified from storm water outfalls, creek crossings and infrastructure failures. Fecal coliform sampling was conducted in conjunction with stream walks only when it was necessary for the identification of fecal sources. 3 'OrYlq'N OF STALLINGS 2012 Am1Ua1TMDL Report As it result of the stream walks, the following; issues were reported: •. One illicit discharge was discovered and corrected; • Several dry weather flows were observed, evaluated, and found not to be illicit discharges; • Seventeen (17) storm water infrastructure issues (damaged pipes, sink holes, etc.) were identified that could cause excess sediment loading to Goose Creek and tributaries to Goose Creek. Thesc issues were reported for follow-up and corrective action. A full copy of the Goose Creek TMDL Stream Walk report is included as Appendix C. Section 3.0 BMPs irr TMDL Wrrtersherls Without WLAs For watersheds that have a `TMD11 without a specific WLA, the Town of Stallings implemented tailored strategies to enhance water quality recovery. 3.1 Illicit Discharge Program During the reporting period, the Town ol-'Stalling� continued to Implement the Town's Illicit Discharge Detection and I. Irmrnation program, which Includes the identification of ol.1tf2111S, visual inspection of utility crossings and evaluation of any dry weather flows. 3.2 Stream Walks During; FYI 1-12, The "Town of'Stallings performed stream walks in the TMDL waterslicds within the Town ol'Stalling;s. The purpose of*these walks was to identify and eliminate all Pollution sources identified from storm water outfalls, creek crossings and infraslrUCtUre tailures. The Town of Stallings will continue implementing; stream walks as described in the Storm Water Management Program Plan within these TMDI., watersheds. Section 4.0 Sunrnrtary of Future BMPs 4.1 Goose Creek Watershed During; FYI 1-12, the "Town of'Stallings continued to expand on efforts to reduce fecal coliform loading; to Goose Creek. Specifically, these efforts included: 4 •'-'•rrrwn i�r STALLINGS 1 Ml�l. Report2012 Annual �...= NOHIli CAROLINA • Continued partnering with Mecklenburg County and the Towns of Mint Hill and Indian "frail to implement the Goose Creek WQRP. • Identified and inspected septic systems within the Goose Creek Watershed by partnering with the Union County Health Department in order to identify and correct deliciencies and failing; systems. • Walking; streams within the Town of Stallings (including Goose Creek) to identify and eliminate potential pollution sources. • The "Town of Stallings post -construction ordinance will be implemented to continue focus of reducing turbidity and fecal coliform bacteria as primary pollutants of concern. Each of these BM1 s will be re-evaluated annually for effectiveness at reducing focal coliform loads to Goose Creek and re -initiated on a continuing basis as determined necessary. Based on the results from the F Y 1 1- 12 activities, the "Town of� Stal lings recommends c011tinual implementation of the Goose Creek WQRP. The Town of Stallings recommends walking; 113 the length of streams within the Town (including the Goose Creek Watershed) each fiscal year. In this manner, each mile of streams within the town will be assessed every three years at a minimum. The Town of Stallings also recommends conducting follow-up septic system inspections within the Goose Creek Watershed on a 5-year cycle to ensure that existing systems are maintained and functioning properly. The results of these BMPs will be included in future annual reports. 4.2 TMD11 Watersheds Without WLAs Tlie Town of Stallings will continue to implement enhanced strategies and measures within these watersheds including: • Enhancing Public lsducation efforts by targeting turbidity and fecal coliform as the main pollutants of concern. • The Town ol'Stalling;s post -construction ordinance will be implemented to continue the focus of' reducing turbidity and fecal coliform bacteria through implementation of structural BMPs. In addition, Stallings post -construction ordinance requires additional storm water detention and peak control above that required by the state minimum standards which helps protect stream habitat by minimizing stream bank erosion caused by large volume flows. • Enhancing; detection of illicit discharges by having staffcontinue performing; stream walks to proactively look for illicit discharges and connections that can further degrade stream water quality and habitat. • Continuing to actively inspect storm water infrastructure to identify possible issues within the system that could cause increased turbidity and degraded habitat.

The stream miles walked were all located in the Goose Creek watershed downstream of Stevens Mill Road as shown on the Union County GIS stream coverage. The subject area was bounded on the west by 1-485 and on the east by Mill Grove Road. The mileage walked was bounded to the north and the south by the town boundary, but included streams that drained the Emerald Lake Country Club Golf Course and a small portion of'the Steven's Mill Subdivision. 2.0 Purpose The stream walks were primarily performed to fulfill the requirements of the Goose Creek Water Quality Recovery Plan for locating and reducing the fecal coliform loading in the Goose Creek Watershed as required by the Goose Creek Total Maximum Daily Load (TMDL) for fecal colilorm. In addition, these stream walks I'ulfill other elements of -the Town of' Stallings Storm Water Managcnient Program Plan required by the Town's Phase 11 NJ'DE-S permit (Permit # NCS000395) such as: • Updating storm water outfall maps, • Maintenance of storm water conveyance systems, • Detection of dry weather flows, and • Detection and elimination of'illicit discharges and connections, Stream walks serve not only to meet permit conditions, but more importantly help the Town of Stallings reduce polluted run-off from entering streams. 3.0 Methodology Stream walks were conducted during baseflow conditions. For the purposes ol�this report, baseflow conditions are defined as less than 0.10 inches of precipitation occurring in a 24-11our day during the previous 72-11our period. The last observed rainfall event prior to the November 9, 2011 stream walk occurred from November 3-4, 2011 , at which time 1.00 inch of rainfall was recorded. The next rainfall event occurred on November 10, 2011, however only 0.03 inches of' rainfall were recorded. All precipitation data reported here was taken from the United States Geological Survey (USGS) real-time network website; raingage #350857080383245, CRN-67 "Thompson Rd. Mint Mill, NC. This appears to be the closest active USGS raingage to the project area. During the stream walks, staff looked for dry weather flows, discoloration, sewer fungus, suspended solids, oily sheen, dead organisms in or around the stream and other indicators typically associated with pollution discharges. This included any odors typically associated with r rr,u°N 6r Goose Creek TMDL Stream Walk Report >rj�,_ STALLINCS sewage, petroleum or chemical pollution. Any unusual or atypical conditions were traced Upstream to identify potential sources, and the sources were noted if identified. During the stream walks, each component of the storm water infrastructure (feature) encountered was geo-located, inspected and photographed. Geographic locations were determined using a Geographic Positioning System (GPS) enabled camera (Cannon Powershot SX230 I -IS) where possible. When no GPS was available, features were located using traditional mapping techniques and coordinates were determined from Google Maps. For each feature encountered, the following information was collected: feature ID (assigned), Latitude/Longitude (decimal degrees), feature type (ditch, culvert, pipe, tributary), feature material (earthen, corrugated plastic, corrugated metal, concrete, RCI', PVC, black iron), diameter (inches), shape (circular, channel, flared), dry weather flow present (yes, no), outfall condition (good, fair, poor), stream bank location facing downstream (right, left), suspected source and any comments. 4.0 Summary of Findings 4.1 Illicit Discharges One feature was identified as a suspected leaking sewer aerial (Item 9 on `table 1), and one illicit discharge (discharge of used oil and golf course chemicals) was identified at Emerald Lake. Country Club Gol l' Course (Item 26 on `fable 1). Both of these were reported to the ']'own of Stallings f-or follow-up investigation and resolution in accordance Willi the "town of'Stallings Illicit Discharge Detection and Elimination program. 4.2 Storm Water Infrastructure ManIling "There were 168 features inspected and cataloged; including one sewer line aerial (black iron pipe), 58 culverts, 40 ditches, 65 pipes, three pond weirs, and one tributary. Dry weather flows were present at 24 Features during the stream walk. Each of these dry weather flows was evaluated and/or traced to a source. Based upon the evaluation, none of the dry weather flows were from suspected pollution sources. The location of the storm water infrastructure is shown on Figure 1. 4.3 Storm Water Conveyance System Inspection During the stream walking activities, there were several potential infrastructure issues identified with the storm water conveyance system: • three corroded or damaged storm water pipes, • six pipes with partial blockage clue to sediment or debris, • one cracked concrete headwall, • one sewer lateral acting as a debris dam, • one exposed sewer lateral due to erosion, • three pipe joint separations, and • two areas where sink holes were forming near storm drain pipes These storm water infrastructure issues were reported to the Town of Stallings maintenance staff for prioritization and follow-up.

Division of Water Quality that a Phase I jurisdiction is subjccl to a "TMDL for a certain stream segment, the Town of Stallings will establish a TMDL Water Quality Recovery Program for that stream segment. On August 10, 2006, the "Town of'Stallings received written notification from the N.C. Division of Water Quality that it is subject to the approved fecal coliform TMDL for Goose Creek. The "Town of Stallings (working cooperatively with Mecklcnburg County Water Quality Program) subsequently completed a TMDL Water Quality Recovery Program Plan for the Goose Creek TM DI., which was submitted to the N.C. Division of Water Quality on July 9, 2008 for compliance with the above described permit requirement. Implementation ofthe Plan began in July 2008. Input received from the Advisory Group formed to facilitate the implementation of this Plan resulted in revisions that were subsequently submitted to the N.C. Division of Water Quality on November 13, 2009, Implementation of this Plan began in November 2009. The Town of Stallings has continued working cooperatively with Mecklenburg County Water Quality Program and the Towns of Mint Hill and Indian Trail to implement the requirements of this Program. L2 Purpose The purpose of the Goose Creek Water Quality Recovery Program (WQRI') is to achieve and maintain compliance with the Water Quality Recovery Program for the Goose Creek Watershed for Fecal Coliform Bacteria. The WQRP requires an annual report be submitted to the North Carolina Division of Water Quality (NCDWQ) documenting activities completed in progress towards meeting the TMDL requirements. The Towns of Mint Hill, Indian Trail, and Stallings have worked cooperatively on the development and implementation of the WQRP. The WQRP annual report was submitted by the Mecklenburg County Water Quality Program to NCDWQ on July 21, 2010 and updated on September 30, 2010. This report addendum documents additional activities for FY09-10 performed in the Town of Stallings from October I, 2009 to Scptember 30, 2010 (not included in the updated annual report) in response to comments during the annual Advisory Group meeting held on September 15, 2010.

Section 2.0 BMP Implementation In addition to the Best Management Practice (13M1") updates already reported in the WQRP annual report submitted to NCDWQ in July 2010, the following sections highlight other BMPs being implemented by the Town of Stallings. 2.1 Utility Crossings and Outfall Inspections During the reporting period, the "Town of Stallings re -inspected previously identified utility crossings and storm sewer system outfalls to identify potential sources of pollution including impacts from fecal coliforrn. A total of 14 outfalls and six (6) utility crossings were inspected during the month of September 2010. There were no identified issues with any of the utility crossings. However. two (2) storm water outfalls were observed to have dry weather flow greater than 72 hours after a rain event. Within the next 30 days, the Town of Stallings will evaluate the two (2) outfalls that contained dry weather flow to determine the source of non -storm water flow and follow procedures contained within the Town's Illicit Discharge Detection and Elimination program to eliminate the discharge. 2.2 Septic System Evaluations To help identify and eliminate possible sources of kcal coliform within the Goose Creek Watershed, the Town of Stallings began identifying households within the Goose Creek watershed that use septic systems as a means to dispose of sanitary wastewater. Based upon results from septic systems in the Town of Mint Hill, septic systems can contribute to fecal coliform load if failing or in need of repair. As a first step in evaluating septic systems, the Town of Stallings must identify which properties utilize septic systems to dispose of sanitary wastewater. To date, the 'Town of Stallings identified one neighborhood, the Golden Acres Subdivision that uses septic systems. A total of 51 households within this subdivision use septic systems. `The `Town of Stallings will continue to investigate additional properties that utilize septic systems. The Town of Stalling is in the process of partnering with the Union County Health Department (the department with permitting authority over septic systems) to perform inspections of all identified septic systems in the Goose Creek watershed to determine if the systems are failing and thus could be a source of fecal coliform. An example inspection form that could be used to collect septic system information is provided as Appendix A. The actual form used will be coordinated with Union County Health Department. 2 SIMIN O Goose Creek TMDt,Annual Report Addendum TALLINCS" 2.3 Stream Walks During FYI OTT I1, The Town of Stallings will begin a program ofwalking all streams in the Goose Creek Watershed within the Town of Stallings on a three-year (3-yr) rotation period.
