Per the Phase 11 Post Construction and Illicit Discharge and Connection Ordinance, any liquid, solid, gas, or other substance other than stormwater that is permitted to go into a stormwater conveyance, waters of the state or onto the land in a way that it is likely to enter a stormwater conveyance or waters of the state is considered an illicit discharge. Discharges that are prohibited specifically by the Phase 11 Post Construction and Illicit Discharge and Connection ordinance include, but are not limited to: oil, anti- freeze, chemicals, animal waste, paints, garbage and litter. 8.2 ALLOWABLE NON-STORMWATER DISCHARGES There are non-stormwater discharges that are pern-dtted to enter a stormwater conveyance or waters of the state if the discharges associated with the list of allowable non-stormwater discharges do not significantly impact water quality. Allowable non-stormwater discharges are listed in Section 25-28 of the Phase 11 Post Construction and Illicit Discharge and Connection Ordinance. 8.3 AREAS OF CONCERN Areas of concern within the Town of Mooresville for this program include areas that have a history of illicit discharges, areas with a high density of old sewer or clusters of sewer issues, areas that discharge to Water -Supply Watersheds, areas that have a high density of industrial facilities or facilities with industrial NPDES permits, and areas of town with infrastructure more than 50 years old. These areas are targeted for public education, storm drain marking, and dry weather flow detection inspections. 8.4 LEGAL AUTHORITY 8.4.1 TOWN OF MOORESVILLE POST CONSTRUCTION AND ILLICIT DISCHARGE AND CONNECTION ORDINANCE The Town of Mooresville Post Construction and Illicit Discharge and Connection Ordinance became effective September 2, 2014. This ordinance establishes the legal authority to prohibit illicit connections and discharges, defines illicit discharges and connections, prohibited discharges, allowable non- stormwater discharges, and outlines procedures for enforcement and violations. 8.4.2 RIGHT -OF -ENTRY Section 25-31(b) of the Phase 11 Post Construction and Illicit Discharge and Connection Ordinance states that the Stormwater Program Specialist "shall have the authority, upon presentation of proper credentials, to enter and inspect any land, building, structure or premises to ensure compliance" with the Phase 11 Post Construction and Illicit Discharge and Connection Ordinance. Page 15 The stormwater drainage system within the Town of Mooresville corporate limits, including major outfalls, is mapped using ArcGIS. ArcGIS shows approximately 120 miles of storm drainage pipe, approximately 11,000 drainage structures and approximately 1000 outfalls (206 of which are considered major outfalls). This map is maintained and updated periodically by Town employees and can be used in tracking illicit discharges. 9.1 MAJOR OUTFALL INVENTORY Major outfalls are tracked via ArcGIS in the SWTest Stormwater database on the Town ArcGIS server. Outfalls are tracked under the Drainage Structures feature layer along with catch basins, inlets, outlets, etc. A separate feature layer has been created to track Major Outfalls and Inspections off the server. If new Major Outfalls are added or updated by field personnel in either of these feature layers, it is the responsibility of the Stormwater Program Specialist to make sure they are both updated and accurate. 9.2 PERSONNEL The Stormwater Program Specialist and Town GIS personnel are responsible for maintaining Stormwater infrastructure GIS databases and maps. Properly trained Stormwater Maintenance personnel with ArcGIS Collector app access frequently update inventory from the field and track infrastructure conditions. Major outfalls (outfalls that are 36 inches or greater, or serve a drainage area of more than 50 acres) are to be inspected at least once during the 5-year permit cycle. Major outfalls are to be evaluated ideally during a period of at least 72 hours without rainfall. The objective of these inspections is to identify discharges from a stormwater outfall during a period without rainfall and to characterize observed discharges and facilitate the detection of illicit discharges. 10.1 INSPECTION PROCEDURES 10.1.1 BEFORE INSPECTION Outfall inspections should be conducted by teams of at least two (2) employees, if possible. If the outfall is on private property, notify the property owner either in writing, by phone, or in -person before entering the property. When conducting a dry weather flow outfall inspection, employees performing the inspection should ensure they have the following materials before they leave to conduct inspections: - iPad or Mobile device equipped with - Measuring Tape ArcGIS Collector App - Flashlight - Water Sampling Kit - High visibility vest/ other apparel - Protective footwear Page 16 10.1.2 DURING INSPECTION Inspections are to be completed digitally via Survey123 following the below steps (a sample of the inspection form can be found in Appendix A). 1. Open the Web Map for Stormwater: Major Outfalls in the Arc Collector App on a mobile device a. If the device does not have the Collector App, navigate to the internet browser and open the Web Map from ArcGIS Online 2. Select the facility/ operation you would like to inspect to activate the Pop -Up Window 3. Within the Pop -Up Window, follow the link'Go to Facility Inspection Form in Survey123 App' a. If the device does not have the Survey123 app downloaded, follow the link'Go to Facility Inspection Form on Survey123 Website' to open in a browser 4. Digitally Complete Form Fields 10.1.2.1 EVALUATION GUIDANCE Before beginning the evaluation, complete the background information section of the "Major Outfall Inspection" form then work through the below inspection fields. 1. Outfall ID This is the OBJECTID in the Town of Mooresville ArcGIS map. This field will automatically populate when the Survey is opened through the ArcGIS Collector pop-up window. **If the outfall was just created, it will not have an Outfall ID. A unique identifier should be assigned to it using the following naming convention. First and Last initial of inspector name followed by the date. Ex. John Smith logged an outfall on July 21s', 2020. Outfall ID= JS072120 2. Subwatershed Use the Town of Mooresville ArcGIS map to determine the subwatershed that the outfall is located within (Dye Creek, Coddle Creek, Back Creek, Reeds Creek, South Fork Withrow Creek, WS-IV-PA Catawba/Lake Norman, or WS-IV-CA Catawba Lake Norman). 3. Today's Date The date of the outfall evaluation. 4. Form Completed By Name of the employee completing the evaluation. If the evaluation is being completed by a team, use the name of the team leader. 5. Time The time the employee arrived at the outfall. 6. How long since last rainfall Page 17 Check the box that corresponds with approximately how many days it has been since the last rainfall event. Outfall evaluations are ideally completed 2-3 days after the last rainfall event and should not be completed when it is actively raining. 7. Location notes Note what drains to the outfall or what the outfall is located near such as neighborhoods, communities, business parks, commercial areas, businesses, construction activities, etc. that may have an impact on the outfall or that you believe is applicable to the evaluation. Once you have arrived at the outfall's location and have completed the background information section, complete the section of the Outfall Evaluation Form, "Outfall Description". 1. Pipe material Check the box that corresponds with the material of the pipe outfall. RCP = Reinforced Concrete Pipe, CMP = Corrugated Metal Pipe, HDPE = High -density Polyethylene (appearance of black corrugated plastic pipe), PVC, Steel, or choose other if none of the available options match the actual outfall pipe material. 2. Pipe Diameter Measure the diameter of the pipe from one side to the direct opposite side of the pipe and record the number in inches. If the pipe diameter information is available on the ArcGIS system you can record that number on the form and verify it during the evaluation. 3. End of Pipe Flows Into Mark the box that corresponds with the feature that the pipe outfall discharges into (roadside or open ditch, stream, lake, wetland, or other. Other may include SCM such as a wet detention pond or bioretention area). 4. End of Pipe Condition Mark the box that corresponds with the apparent condition of the pipe outfall. If the pipe is clear of debris and is in good structural condition so that water can run freely through the outfall, mark "Open". If the pipe is clogged with debris or sediment so the flow of water through the pipe is impeded, mark "Closed/ Clogged". If the pipe is crushed or damaged, mark "Crushed". If you marked either "Closed/ Clogged" or "Crushed", estimate the fraction that the pipe is crushed or closed (i.e. if the pipe is 2/3 full of debris, note 2/3 for fraction closed/ clogged/ crushed). After completing the Outfall Description section, complete the section "Physical Indicators". In this part of the outfall evaluation, determine if any physical indicators of an illicit discharge are present. Check the outfall structure for any evidence of stains, deposits, changes in vegetation around the outfall structure, and structural damage. If there is water flowing from the outfall structure, check the water coming from the outfall structure for signs of an illicit discharge (color, odor, turbidity, floatable matter, grease, oil, etc.). Use the questions in this section to determine if an illicit discharge is present. If at any point during the investigation you believe there is an illicit discharge present, and there is water actively discharging Page 18 from the outfall, use the Water Sampling Kit at your disposal to determine if the water flowing from the pipe falls within acceptable levels for the tests being performed. Table 1: Allowable Range/Limits for select chemical parameters Chemical Parameter Allowable Range/Limit pH 6.0-9.0 Follow the directions in the handbooks equipped in the water sampling kit for the Tracer PockeTesterTM and Lamotte Smart3 Colorimeter to conduct relevant tests. The PockeTesterTM should be utilized first to test for pH, TDS and salinity. If the PockeTesterTM shows the water sample is outside the allowable range/limit for pH, the sample should be further tested using the Colorimeter. The Colorimeter is programmed with the ability to test for a wide variety of potential pollutants. Tests should be chosen based off what the suspected pollutant is. Testing procedures should be carefully followed to assure there is no cross -contamination of the samples. If testing is inconclusive, the inspector is to contact the Wastewater Treatment Plant and request that they come test a sample of water coming from the outfall. Wastewater Treatment plant has indicated that they can field test for pH, dissolved oxygen (DO), total suspended solids (TSS) and temperature. If there is water flowing from an outfall and you believe an illicit discharge is present, do not leave the outfall until the Illicit Discharge Investigation is complete. (See procedures in Section 6). 1. Water flowing from the end of the pipe Check the box for "Yes" if there is water coming from the end of the pipe and "No" if there is not. If there is water coming from the end of the pipe, determine if the water is clear, muddy or colored (and describe the color of the water in the space provided) and check the appropriate box. If the water is colored or muddy, also mark the box under results for "Evidence of Illicit Discharge". 2. Evidence of petroleum products If there is evidence of petroleum products in the water coming from the end of the pipe or in the area surrounding the outfall, it may be evident by a sheen on the water. If you believe there is evidence of petroleum products in the water or area around the outfall, describe what you see in the space provided. If there is evidence of petroleum products, also mark the box under results for "Evidence of Illicit Discharge". 3. Is there an odor present? Determine if there is an odor present around the outfall structure or if there is water actively flowing from the outfall, if the water has an odor and check the applicable box. If there is an odor present, describe the odor. Examples of an odor include: decaying products, rotten eggs, spoiled milk, yeast, a burning odor, sweet or flowery, gas or petroleum. If an odor is present, also mark the box under results for "Evidence of Illicit Discharge". Page 19 4. Floatables present Examine the end of the pipe, the outfall structure and the area the pipe discharges into for any floatables. Floatables include: paper, grease, suds, oils, grease, etc. If you note the presence of toilet paper in or around the outfall, immediately contact the Water Sewer Maintenance Supervisor. If there are floatables present, also mark the box under results for "Evidence of Illicit Discharge". 5. Sediment and/or debris in the end of the pipe Note if there is any sediment or debris (branches, leaves, trash, etc.) in the pipe outfall or surrounding area. If there is, check the box for "Yes" and then describe what is in the pipe (trash, sediment, leaves, etc.) and the fraction of the pipe that is full of sediment or debris (i.e. if the bottom third of the pipe is full, note in 1/3 in this section). 6. Staining or growths on the pipe Examine the outfall structure and look for any staining, deposits or growths on or around the outfall. This may include: colored crystals, salt crystals, brown or black stains, powders, etc. If there are any stains, growths or deposits on the outfall pipe or structure, check the box for "Yes" and then describe what is present. If there is evidence of stains or growths, also mark the box under results for "Evidence of Illicit Discharge". 7. If the pipe flows into a ditch or a ditch is nearby Check the box that corresponds to the condition of the ditch regarding sediment and debris. If there are sediment deposits or trash within the ditch, depending on the amount of sediment and debris may either need to be monitored or need maintenance. Check the box that corresponds to the state of the vegetation within the ditch. If the vegetation is dying or appears unhealthy (keep in mind that winter months may cause vegetation to appear as though it is dying when it may be dormant), check the box that corresponds with "yes, needs maintenance". Also, some ditches are not designed to have vegetation (i.e. concrete ditches or riprap lined ditches) and so in this instance, check the box that corresponds with "No". 8. Erosion occurring at the end of the pipe If there is erosion occurring under and/or around the end of the pipe or in the ditch or waterbody that the pipe discharges into, mark the box that corresponds with "Yes" and describe the location and extent of the erosion present. If there is erosion occurring at the end of the ditch, also mark "Yes" under Results and Maintenance Needed. If no erosion is visibly present, mark "No". 9. Description of any other visible issues Describe any other visible issues you may see in the outfall or in the surrounding area. This may include any other information you believe will give a clearer picture of the outfall or the surrounding area that may contribute to the state of the outfall. Include description of the state or the riprap (if riprap is present at the outfall) and note if the riprap has been displaced or needs to be replaced, and if there is any structural damage to the outfall. Page 110 10. Take photos of the outfall and surrounding area. If you have marked the box "Yes" for any category, make sure to take photographs that clearly show the physical indicator. Photos may be taken directly from the Survey123 app or selected from the camera roll on the device. Complete the results section by checking the box for either "No" or "Yes" under evidence of an illicit discharge. If you check the box for "Yes", immediately begin investigating the illicit discharge using the Illicit Discharge Report Form and/or Illicit Discharge Tracking Form available in Survey123. If the employee requires additional assistance to conduct the illicit discharge investigation, the employee should contact their supervisor or the Stormwater Program Specialist. Do not leave the site of an active illicit discharge. See Section 6.3 Tracking Illicit Discharges of this manual for how to investigate the illicit discharge and track it back to its source. If the outfall or outfall area requires maintenance (read back over the survey before submitting and if you have marked any box that corresponds with needs maintenance), check the box for yes here and submit the survey. 10.1.3 POST INSPECTION 1. If edits need to be done after the inspection form has been submitted, this can be done on the Survey123 website. a.

In the work order, note that it was generated due to findings during an outfall evaluation and describe the scope of work to be completed. 10.3 PERSONNEL The Stormwater Program Specialist is the primary personnel responsible for executing Illicit Discharge Detection and Elimination Program. The Stormwater Program Specialist is to maintain Major Outfall inventory, related ArcGIS data and outfall investigation report records. The Stormwater Program Specialist and properly trained Stormwater Maintenance personnel are responsible for carrying out Outfall Inspections. The Stormwater Program Specialist will be the primary person to train employees on outfall inspection procedures and on proper use of the water sampling kit. Page Ill 10.4 DOCUMENTATION AND RECORD KEEPING e Major Outfall Inventory- Stormwater OneDrive & ArcGIS Online * Major Outfall Inspection Logs - Pre 2020: logged in Major Outfall Microsoft Access Database Stormwater One Drive. Inspection Forms are saved in corresponding inspection year folders on Stormwater OneDrive. 2020-Present: logged in Major Outfall Inspection Spreadsheet on Stormwater OneDrive and inspection record saved digitally in ArcGIS Inspection Table. Digital Inspection form is exported out and saved in individual folders with photos on OneDrive. -Maintenance Records- Work orders are tracked and logged through iWorQ system. Personnel are able to search based off date, problem code, key words, etc. 11.1 PUBLIC REPORTING MECHANISMS 11.1.1 STORMWATER HOTLINE Citizens are urged to call the Stormwater Program Specialist if they witness or suspect an Illicit Discharge. The general Phone Number for the Public Operation Center is publicized as the 'Stormwater Hotline' as the Assistant to the Assistant Town Manager can properly route calls to the available personnel to address the issue at hand. If the issue occurs after normal operation hours, citizens are directed to call the Town of Mooresville Police Department who will then contact the Stormwater Maintenance Supervisor. 11.1.2 IWORQ/TALK TO MY CITY Citizens can report concerns directly from the Town of Mooresville website homepage. The "Report a Concern" icon will reroute viewers to the iWorQ Service Request Website. From there, citizens are able to specify which department their concerns are relevant to, type of problem, contact information and a description of the issue. Stormwater is listed as a Department in iWorQ and has a special problem code that can be selected for illicit discharges. When an iWorQ ticket is submitted, an email notification will get sent to the Storrawater Program Specialist and the Stormwater Maintenance Supervisor. 11.1.3 TEXT MY GOV The Town started using Text My Gov in 2020 as an easier way for citizens to find information or report potential issues 24/7. By using keywords such as Storrawater or Illicit Discharge, reports can get routed to the proper department. The number for Text My Gov is 704-703-4030. Page 112 11.2 ILLICIT DISCHARGE INVESTIGATION PROCEDURES When a suspected illicit discharge is reported, an investigation of the suspected illicit discharge will be conducted within two (2) business days of the report by the Stormwater Program Specialist, or other trained Stormwater Maintenance Personnel. The individual who received the illicit discharge report will provide background information to the Stormwater Personnel to create an Illicit Discharge Investigation Report. The following steps should be taken to document the investigation in Survey123 (a sample of the inspection form can be found in Appendix A). 1. Open Survey123 from Mobile App or from a Web Browser 2. Select the survey for 'Illicit Discharge Investigation Form'. 3. Digitally Complete Form Fields using the guidance in 6.2.1 a. There are several steps to the inspection process that can occur over the course of several days. The following steps should be followed to allow for editing reports. i. Survey123 App: the report can be saved in drafts for later editing. ii. Survey123 Website: reports can not be saved and will have to be submitted and edited from the desktop website using the following workflow: My Surveys4Select Survey4l3ata4Select inspection record from table4 Edit This Record4Make necessary changes4Submit 4. Track Illicit Discharge to source using procedures in Section 6.3 (if necessary) 5. Submit Report 6. Export Report to Template form a.

Save PDF of report and any relevant photos in appropriate Fiscal Year subfolder in the Illicit Discharge Reports folder on the Stormwater OneDrive. a. Files should be named by the date and location of the reported illicit discharge. Ex. 21.02.25-456MainStreet 11.2.1 REPORT GUIDANCE Section 1: Reported Information of the Illicit Discharge Investigation Form, which includes: 1. Date and Time of the report. 2. The weather at the time of the report. 3. The name and contact information of the individual reporting the illicit discharge. 4. When the suspected illicit discharge was seen. 5. Where the suspected illicit discharge was seen. 6. What the individual believes the suspected illicit discharge to be. 7. If a business is involved in the suspected illicit discharge. 8. And any other information the individual can provide. Within two (2) business days of receiving the report, the employee responsible for conducting the investigation will begin the investigation and complete Section 2: Investigation of the Illicit Discharge Investigation Form. The investigator will record: Page 113 1. Date and time the investigator arrives at the location of the suspected illicit discharge. 2. The weather at the time of the investigation, noting whether it is currently raining. 3. The name of the employee conducting the investigation. 4. Location of Investigation: using the interactive map either type in the address of the location or drop a pin at your current location. 5. Location notes: what is near the site of the suspected illicit discharge. For example, list any businesses, construction sites, residences, etc. that are nearby. 6. Description of illicit discharge: describe if there is any evidence of the reported illicit discharge present at the site. Note: a. If there are any stains at the site or in the area leading to the site of the suspected illicit discharge. b. Discoloration around the site or in the area leading to the site of the suspected illicit discharge. c. If there is an odor present at the site. d. If the storm drain, outfall or conveyance is clogged or blocked in any way. e. If there is any flow coming from the pipe, check the flow for floatables, sheen, suds, or any other signs of an illicit discharge. If possible, use test strips available to you to test water coming from the pipe to determine if it is within normal levels. If you believe at any point that the suspected illicit discharge is sewage, contact the Water Sewer Maintenance Supervisor. 7. Note if there have been previous reports of illicit discharges from this location or facility. This information will be considered if enforcement is required. 8. If there is evidence of an illicit discharge, check the box for yes. If there is evidence of an illicit discharge but the source cannot be determined, check the box for track illicit discharge to source and proceed to Section 6.3 Tracking Illicit Discharges. If there is water flowing from the site of the illicit discharge, use available Tracer PockeTesterTM in the water sampling kit to determine if the water is within acceptable pH levels. If at any point, you believe sewage is present, immediately contact the Sewer Maintenance Supervisor. If there is no evidence of sewage but there are other physical indicators and pH is outside of the allowable range/ limit, utilize the Smart3 Colorimeter equipped in the water sampling kit to conduct additional tests levels. If results are inconclusive the investigator is to contact the Wastewater Treatment Plant for assistance on additional field testing of water discharging from the outfall (see Section 5.1.2.1 for additional information on water sampling). Once the investigator has completed the form and determined if an illicit discharge is present, the survey should be submitted through Survey123. The Stormwater Program Specialist will then determine the enforcement action to be taken, if necessary. See Section 6.6 titled 'Enforcement Procedures' for recommended action if source can be determined. If the illicit discharge is a petroleum product or hazardous substance, see Appendix C for more information on reporting spills of petroleum or hazardous substances. If there is evidence of an illicit discharge and the entity responsible for that discharge has been contacted, complete the follow-up portion of the Illicit Discharge Investigation Form in Survey123 within 3 days following the date that the illicit discharge needed to be corrected by. If the illicit discharge has been corrected, close the investigation, and note the date the investigation was closed. If the illicit discharge Page 114 has not been corrected, refer to Section 6.6 titled 'Enforcement Procedures' for details regarding how to proceed. If there is more than one suspected illicit discharge to be investigated, prioritize investigations based on the possible impacts to public health and safety that the suspected illicit discharge could have. If there is more than one possible illicit discharge that could have a negative impact on public health and safety, prioritize the investigations of obvious illicit discharges over suspected illicit discharges. 11.3 TRACKING ILLICIT DISCHARGES If the source of the illicit discharge that was reported or discovered during regular outfall evaluations cannot be immediately determined, complete the form titled "Illicit Discharge Investigation Tracking Form" in Survey123. The purpose of this form is to note the storm drain structures or portions of the stormwater conveyance system checked for evidence of the illicit discharge that was reported or discovered so that the illicit discharge can be tracked back to its source. A sample of the tracking form can be found in Appendix A of this manual. 11.3.1 TRACKING PROCEDURES To track an illicit discharge back to its source, utilize the Stormwater Inspections Web Map on ArcGIS Online (or on the Collector app) to show the outfall or inlet where the evidence of the illicit discharge was initially discovered as well as the inlets and portions of the stormwater conveyance that lead to where the evidence of an illicit discharge was found. This map will be used to choose the path of the investigation. Illicit discharges may be tracked using one of the following investigation methods: 1. Visual Inspection - This investigation method will involve manually opening manholes and removing storm drain inlet grates and covers and visually inspecting the opened area to determine if there is evidence of the illicit discharge present. 2. Camera - This investigation method involves using the camera to inspect the storm drainage pipes that lead to the location of the illicit discharge to determine where the evidence of the illicit discharge begins. **Follow the workflow from Section 6.2 procedures to open, edit and save & export Surveys in Survey123. Before tracking the illicit discharge, complete Section 1, Background Information, of the digital form. 1. Investigated By: The name of the employee tracking the illicit discharge. If more than one employee is present, note the name of the team leader. 2. Investigation Method: Note which of the above methods (visual or camera) that will be used to track the illicit discharge. 3. Date and Time that tracking of the illicit discharge began. 4. Weather at the time tracking of the illicit discharge began. 5. Note the trigger for tracking the illicit discharge. Triggers include: evidence of an illicit discharge is found during an outfall evaluation, report of an illicit discharge or other. 6. Describe the illicit discharge that is being tracked. Include all physical characteristics that indicate an illicit discharge to assist in tracking the illicit discharge through the MS4. Page 115 7. Note any businesses, facilities or other potential pollution sources that are located nearby or directly upstream of the site where the illicit discharge was found. To begin tracking the illicit discharge, start at the next storm drainage structure upstream from where the evidence of the illicit discharge was found. If multiple structures feed into the structure where the illicit discharge was found, check these structures and then follow the line that has the evidence of the illicit discharge. Using the investigation method chosen, complete the table in Section 2 of the form. For each structure checked for evidence of the illicit discharge: 1. Structure ID Number This is the OBJECTID Number for the structure (inlet, pipe, outfall, etc.) as listed on the Town of Mooresville GIS. 2. Evidence of Illicit Discharge Present Type yes or no and if yes, also describe the evidence found at that structure. 3. Nearby potential pollution sources Describe any potential pollution sources near the structure that is being investigated. i.e., list any industrial facilities, car washes, residences, commercial properties, etc. that may have contributed to the illicit discharge. 4. Notes Note any other information that you think may be important to the investigation such as what is present at that structure, if any other evidence is found at that structure that may not be connected to the illicit discharge that is being investigated, etc. 5. Continue or Source If there is no evidence of an illicit discharge at that structure or if there is evidence of the illicit discharge but it is not the source of the illicit discharge, note C for continue in this section. If this is the source of the illicit discharge, then note S for Source. Continue the investigation until the source of the illicit discharge is found and then complete the Results section of this form. List: 1. The source of the illicit discharge: this can be a store, industrial facility, restaurant, residential area, etc. 2. The owner of the illicit discharge: this is the individual or body that owns the property on which the illicit discharge originated or is responsible for causing the illicit discharge 3. Address: the address of the owner 4. Contacted By: the name of the Town of Mooresville employee who contacted the owner of the illicit discharge Page 116 5. Contact Date: the date the Town of Mooresville employee contacted the owner of the illicit discharge. Upon determining the source of the illicit discharge, find the name of the owner and the contact information (address, and phone number if possible) and submit the completed form and all related documentation and pictures. The Stormwater Program Specialist will contact the owner of the illicit discharge following the procedures listed in Section 6.6 titled 'Enforcement Procedures' within this manual. If there is evidence of an illicit discharge and the entity responsible for that discharge has been contacted, complete the follow-up portion of the Illicit Discharge Investigation Form within 3 days following the date that the illicit discharge needed to be corrected by. If the illicit discharge has been corrected, close the investigation. If the illicit discharge has not been corrected, refer to Section 6.6 titled Enforcement Procedures for details regarding how to proceed. When the investigation is closed, the exported PDF forms from Survey123 should be saved in the same folder under Illicit Discharge reports on the Stormwater OneDrive. 11.4 ILLICIT CONNECTIONS PROCEDURES An illicit connection is a connection to the stormwater drainage system that is not approved by the Town of Mooresville or that discharges non-stormwater to the stormwater drainage system. Connections to a stormwater conveyance or stormwater conveyance system that allow the discharge of non-stormwater are not permitted per the Post Construction and Illicit Discharge and Connection Ordinance. If an illicit connection is discovered, the Stormwater Program Specialist or their representative will track the connection back to its source using one of the methods discussed in Section 6.3 Tracking Illicit Discharges. Once the source of the illicit connection is determined, the Stormwater Program Specialist will follow the procedures detailed in the Phase II Post Construction and Illicit Discharge and Connection Ordinance to determine the action required by the owner of the illicit connection. 11.5 REMOVING ILLICIT DISCHARGES Spills or leaks of polluting substances released, discharged to or having the potential to be released or discharged to the stormwater conveyance system, are to be controlled, contained, collected and properly disposed. All areas affected by the spill or leak are to be returned to their preexisting condition. The person in control of the polluting substance is to contact the Town of Mooresville Fire Department of the release or discharge as well as making any notifications required by State or Federal Law. Per the Phase 11 Post Construction and Illicit Discharge and Connection Ordinance, illicit discharges or illicit connections are determined to be dangerous to public health or public safety and are declared to be public nuisances. These public nuisances are to be abated in accordance with the procedures detailed in the Town Code of Ordinances. Page 117 11.6 ENFORCEMENT PROCEDURES Once the responsible entity and the source of the illicit discharge or connection is determined, the Stormwater Program Specialist or their representative will contact the responsible entity through either phone call or one of the accepted mailing options detailed in the ordinance to notify the responsible entity of their responsibility to remove the illicit discharge or connection. Follow the flow chart (Figure 1) to determine the enforcement action necessary if evidence of an illicit discharge is found. If a Notice of Violation (NOV) is necessary according to the flowchart in Figure below, the NOV must include the following information: - The nature of the violation - The address or other description of the site upon which the violation is occurring - An order of the necessary action to abate the violation - The deadline for correcting the violation A person who receives a NOV may submit a written request for an extension of time to correct the violation. A request for an extension will only be considered if the responsible entity can show that for reasons beyond the control of the person requesting the extension the violation cannot be corrected in the original timeframe. The Stormwater Program Specialist is to be notified if communication with the property owner or responsible party is necessary as soon as investigation is completed. Page 118 Within 2 business days of Complete: completing the investigation, contact the responsible entity to :Invesstigation notify them of the violation and provide a time to correct the violation Follow-up Investigation q within 3 business days of the end of the timeframe to correct detailed in the notification In Contact the responsible entity with notification that violation has not been corrected Follow-up Investigation within 3 business days of the knd of the timeframe MMMMM given to correct the Finalize Report V1 violation In Compliance? 11.7 PERSONNEL The Stormwater Program Specialist is the primary personnel responsible for executing Illicit Discharge Detection and Elimination Program. The Stormwater Program Specialist is to maintain logs for Illicit Discharge Investigation reports, Illicit Discharge Tracking reports, and all related ArcGIS data. The Stormwater Program Specialist and properly trained Stormwater Maintenance personnel are responsible for carrying out Illicit Discharge Inspections. The Stormwater Program Specialist will be the primary person to train employees on illicit discharges and on proper use of the equipment in the water sampling kit. 11.8 DOCUMENTATION& RECORD KEEPING -Citizen Phone Calls and Emails- tracked via iWorQ -Illicit Discharge Investigation & Tracking- Stormwater OneDrive & ArcGIS Online Pre 2020: documented in'Illicit Discharge Log' spreadsheet. Individual investigation and tracking forms and any photos are saved in corresponding fiscal year folders on Stormwater OneDrive. 2020-Present: documented in'Illicit Discharge Log' spreadsheet on Stormwater OneDrive. Inspection records are saved digitally in Survey123 Data and locations are mapped on the Illicit Discharge map on ArcGIS Online. Digital Inspection forms can be exported out and saved in individual folders with photos on OneDrive. - Enforcement- If a Notice of Violation (NOV) is issued, the nature of the violation will be documented in the illicit discharge report. If a letter was sent to the party, a copy of the letter and certified mail receipt will be saved in the individual folder on the Stormwater OneDrive with any other supporting information. The ArcGIS Illicit Discharge Map should be utilized to identify chronic violators and additional areas of concern. Illicit discharges are prevented using the following minimum measures included in the Town's NPDES Phase 11 Stormwater Permit: public education and outreach, public involvement and participation and municipal pollution prevention and good housekeeping. 12.1 PUBLIC EDUCATION & OUTREACH Public education and outreach efforts include the Town of Mooresville Stormwater website, articles in the Town Voice, classroom lessons, and educational handouts distributed in the field and at events attended by the Stormwater Program Specialist. Public education materials also include industry targeted handouts with information to prevent stormwater pollution and some best management practices to follow. Page 120 12.2 PUBLIC INVOLVEMENT & PARTICIPATION Public Involvement and Participation includes a volunteer storm drain marking program. Volunteers from the community mark storm drains in a chosen location and check the storm drains they mark for illicit discharges or debris. The storm drain markers remind citizens that anything they dump on the street or into a storm drain goes directly to our local waterways without treatment. 12.3 POLLUTION PREVENTION AND GOOD HOUSEKEEPING 12.3.1 MS4 OPERATION AND MAINTENANCE PROGRAM The stormwater maintenance staff is responsible for maintaining the municipally -owned and maintained catch basins and conveyance systems. Stormwater maintenance staff conducts maintenance as well as respond to maintenance requests from citizens. Maintenance of the municipally -owned stormwater conveyance system and regular street sweeping helps to minimize illicit discharges. 12.3.2 EMPLOYEE TRAINING PROGRAM Before conducting a dry weather flow inspection, responding to an illicit discharge report, or tracking an illicit discharge to the source, an employee should familiarize themselves with this manual and associated forms. Employees should be familiar with signs or indicators of illicit discharges and how to use the testing strips or methods listed in this manual. Employees should also be familiar with any applicable safety procedures published by the Town of Mooresville. Town employees receive training once per year that will include information such as what an illicit discharge is and what to do when an employee sees a possible illicit discharge. Training also includes Pollution Prevention and Good Housekeeping and Stormwater Baseline Best Management Practices. If an employee of the Town, during their normal duties, notes or suspects an illicit discharge, they are to contact the Stormwater Program Specialist to report it. Items that should be reported include but are not limited to: witnessing dumping of materials or non-stormwater liquids into a storm drain, stormwater conveyance or materials left in or near a storm drain or other stormwater conveyance, and staining or discoloration in a storm drain or outfall. "For additional information on MS4 Operation and Maintenance Program and Employee Training Program, reference Sections 4 & 5 of the Town of Mooresville Stormwater Pollution Prevention and Good Housekeeping Program and Procedures Manual. The program will be evaluated annually to determine the progress towards the measurable goals detailed in the Stormwater Management Plan. Program evaluation will be completed using the ArcGIS database used to track illicit discharge investigations, the ArcGIS database used to track outfall inspections, and the information regarding the frequency of "hotline" use and the associated number of confirmed reported illicit discharges. This evaluation of the program can help to improve the program by identifying the areas that have the most severe illicit discharge problems so that resources may be allocated to these areas.

How long since last rainfall: mark the box that corresponds with the approximate number of days since the last rainfall event. Outfall evaluations are ideally completed 2-3 days after the last rainfall event and should not be completed while it is actively raining. Notes: If there is anything about the area that you believe is applicable to the evaluation (such as nearby businesses, communities or industries, or any activities you see happening nearby that may explain any evidence of possible illicit discharges or damage to the outfall.) "Take a photo of the outfall and any issues that youfind during the evaluation" Outfall Descriptio Pipe Material: select the pipe material from the list provided or mark "Other" and write in the pipe material if it is not an option provided. Pipe Diameter: Measure the pipe diameter (and confirm with the GIS system if possible) and record (in inches). End of Pipe Flows into: Select the type of waterbody or ditch that the pipe discharges into. End of pipe condition: if the end of the pipe has any structural damage and/or is crushed, mark the applicable box and record the approximate fraction that the end of the pipe is closed. Ehysical Indicators: Water flowing from the end of the pipe: If there is water actively running from the end of the pipe, mark "Yes" and describe the color of the water. If water is colored or muddy, mark "Yes" under "Results: Evidence of Illicit Discharge". Evidence of petroleum: Mark "Yes" if there is a sheen or visible product present, describe what is present, and mark "Yes" under "Results: Evidence of Illicit Discharge". Odor: Mark "Yes" if the water or outfall has an odor, describe the odor in the space provided, mark "Yes" under "Results: Evidence of Illicit Discharge".

Page 128 The Town of Mooresville Post Construction and Illicit Discharge and Connection Ordinance also requires that the Town of Mooresville Fire Department be contacted when a spill occurs. The following NCDEQ website lists the information regarding the reporting of spills of hazardous substances and petroleum: https://deq.nc.gov/about/divisions/environmental-assistance-customer-service/deacs-permit- ggidance / faq #spills The 24-hour emergency response number for reporting spills is: (800) 858-0368 According to the NCDEQ FAQ: Spills - Hazardous & Petroleum and North Carolina's Oil Pollution and Hazardous Substances Control Act of 1978 (§143-215.85(a and b)): If the petroleum discharged, released or spilled: 0 Is 25 gallons or more, or • Causes a sheen on a nearby surface water, or • Is 100 feet or less from surface water body Then the person owning or having control over the oil must immediately take measures to collect and remove the discharge, and report the discharge to NCDEQ within 24 hours of discharge, and begin to restore the area affected by the discharge. If the petroleum discharged, released or spilled is less than 25 gallons, does not cause a sheen on a nearby surface water, and is more than 100 feet from surface water bodies. Then the person who owns or has control over the oil must immediately take measures to collect and remove the discharge. If it cannot be cleaned up within 24 hours of the discharge or causes a sheen on a nearby surface water, the person must immediately notify the NCDEQ. If the petroleum released or spilled in any circumstances does not meet one of the above requirements, or is not permitted by GS 143-215.1, or it is not pursuant to a rule adopted by the Environmental Management Commission or, a regulation of the USEPA, it must be reported to NCDEQ immediately. See the Oil Pollution and Hazardous Substances Control Act of 1978 for more information. The quantities and reporting times for hazardous substances vary. Check the following website for the reporting time and reportable quantity of a hazardous substance: https://www.ega.gov/sites/production/files/2015-03/documents/list of liAL.pdf Page 129 The following log will be used to document any changes to the programs or practices detailed in this manual.
