For each media, event or activity, including those elements implemented locally or through a cooperative agreement measure and record the extent of exposure 712. Target Audience (SW101710) The target audiences for the education program include the general public (newspaper editorials), school children, Internet users and existing utility customers. These audiences were chosen because they represent a broad cross section of Kannapolis's residents, businesses and industries. Schocl children are probably the most impressionable audience and the one most open to a message about pollution prevention. Take-home materials are also helpful since they encourage discussions between children and their parents concerning stormwater issues. Utility bill inserts are an inexpensive way to reach a large number of business and industrial clients. The City will be using other methods of distribution for educational information in the third permit cycle. The Internet provides open access to all members of the public that desire more detailed information on the stormwater program. 7.1.3. Target Pollutant Sources (SW101720) Pollutant sources targeted in this control measure include those sources or activities that produce trash, floatables, chemicals and waste oils, fecal coliform and sediment/erosion. To address targeted sources, stormwater pollution prevention messages target various groups. For children, the messages focus on pollutant sources that are easy to see and understand (e.g. trash, floatables). There has also been an effort toward helping children understand the nature of the storm sewer system (i.e. the water which goes down the storm drain is not treated before it enters the river), Messages targeted to industry focus on good pollution prevention strategies and emphasize that, through the Good Housekeeping/Pollution Prevention Minimum Control Measure; the City is acting as an example to industry. The Utility Bill Inserts target homeowners with messages directed to proper disposal of hazardous waste and proper use of lawn and garden chemicals. Faulty septic systems and related fecal coliform problems will be included as a topic on the Stormwater microsite. 7.1.4. Outreach Program (SW101730) The program, as referenced in the BMP Table 7.1.1, has included: 1. Newspaper opinion pieces written by the City Manager or guest editorialists that presented the City viewpoint on Stormwater Management issues. This is a widely read column and was a good venue to provide the public a first look at Stormwater issues. 2. The existing school information packet program was expanded to include age - targeted messages related to Stormwater pollution prevention. This included information about how children and their parents could get involved in existing Cabarrus County pollution prevention efforts (see section 7.2 for these public involvement activities). Updated: September 12, 2016 NPDES PHASE II — Comprehensive Stormwater Management Program Report 3. The utility bill inserts presented brief messages in a format with which the public was already familiar. Billings to businesses and industry contained more detailed and targeted messages. 4. The web microsite is a general repository for contact information and easily accessible City documents related to Stormwater. 5. Three brochures that focus on proper car washing techniques, cleaning and disposal activities for restaurants, and proper landscaping and pest control techniques were distributed to various audiences within in the City. 6. The continued operation of the City's hotline/ helpline number which regularly fields phone calls from the general public regarding potential illicit discharges. The City reached approximately 20,000 people with some Stormwater related message over the course of the first 5-year permit cycle. 715, Decision Process The City decided to use the methods described in Table 7.1.1 because these presented the best balance between cost and effective education. The City conducted a review of all existing or anticipated education efforts and chose those that would reach a broad audience. The four BMPs chosen are all existing, well proven, methods by which the City communicates with its citizens. The measurable goals are directly related to the target audiences the City would like to reach. The responsible party for carrying out BMP 1 is the City manager since in involves a newspaper column regularly written by the City Manager. The City Manager could designate another party to write about specific Stormwater issues where appropriate. BMPS 2-4 are the responsibility of the Public Information Officer since that individual was already involved in communicating with the public via those methods. 7.1.6, Evaluation The Environmental Stewardship Commission (ESC) was created in 2008 to address the current and future need to value and protect the City's natural resources and to achieve sustainable growth. The group provides policy recommendations to City Council and works on programs and activities related to environmental stewardship. The group meets annually to review all measurable goals to determine if they are being effectively met and if the BMPs are still the best choice to attain the overall stormwater management program objective. This process will continue into the third permit cycle. Updated: September 12, 2016 10 NPDES PHASE II — Comprehensive Stormwater Management Program Report 7.2. Public Involvement and Participation (SW102620) Program requirement: At a minimum, comply with State, Tribal and local public notice requirements when implementing a public involvement/participation program. 721.

Copies of the draft documents were available to the public on the City's website prior to the hearing and were available at the hearing itself. Documentation of the process followed and the Public Notices issued are available upon request. 723, Evaluation The Environmental Stewardship Commission (ESC) was created in 2008 to address the current and future need to value and protect the City's natural resources and to achieve sustainable growth. The group provides policy recommendations to City Council and works on programs and activities related to environmental stewardship. The group meets annually to review all measurable goals to determine if they are being effectively met and if the BMPs are still the best choice to attain the overall stormwater management program objective. This process will continue into the third permit cycle. Updated: September 12, 2016 11 NPDES PHASE II — Comprehensive Stormwater Management Program Report 7.3.

This mechanism 2 must include the ability to identify chronic violators for initiation of actions to reduce noncompliance. Updated: September 12, 2016 NPDES PHASE II — Comprehensive Stormwater Management Program Report 7.3.2, Storm Sewer System Map (SW103220) In order to develop a storm sewer system map the City has identified City owned, operated or maintained roads, drainage easements and City owned property and traversed these areas in search of storm water discharge features, All the qualifying discharges to the "Waters of the State" (as established in the City's NPDES Permit) within these areas were identified as City Outfalls during the first 5-year permit term, located using a field mapping interface, and the corresponding attribute information was collected. All pipes of 12" diameter and greater and outfall channels of equivalent size were inventoried. The City has also begun developing a system inventory map to prioritize preventative maintenance or replacement efforts, to assist with infrastructure master planning, and to track and prevent pollutants from a spill from reaching a local waterbody. It is the intent of the City to incorporate this data into its current work order management system. The City initially performed a storm water system inventory pilot project to provide the budgetary and procedural framework for a complete subsequent system inventory mapping effort. This enabled testing of the database design and work procedures. In addition, the City can now better project costs and resources needed to complete the full storm sewer system inventory. The system inventory process consisted of mapping al! storm water drainage point features, collecting all appropriate corresponding attribute data, and generating a model of the linear drainage network by also mapping all linear drainage features and collecting associated attribute data. The resulting dataset is a closed topological network with embedded relationships between the point features that collect storm water runoff and the linear features that convey the runoff from one feature to another and ultimately to the aforementioned "Waters of the State". As funding becomes available as the third permit term approaches, the City will entertain mapping other portions of the MS4, as well. The City also integrates the mapping effort into a Geographic Information System (GIS). 7.3.3. Regulatory Mechanism (SW103340) In the first permit term, the City developed a comprehensive ordinance enabling this and other stormwater management program initiatives. The mechanism provides for definition and prohibition of illicit non-stormwater discharges, and inspection for and elimination of such discharges. The language prohibiting illicit discharges can be found in the City of Kannapolis Code of Ordinances — Part 2 Code, Chapter 17 Water and Sewers, Article V. Stormwater Utility, Control, and Management, Division 4. Stormwater Control and Management. 7.3.4. Enforcement (SW103350) The ordinance provides for enforcement actions to be taken for illicit discharge violations, including levying penalties against offenders and providing compensatory measures to the City should intervention and removal of the discharge become necessary. The enforcement methodology involves notification of the property owner, establishing a reasonable timeframe in which to address the occurrence, and issuance of.notices of violation and fines. 7.3.5. Detection and Elimination (SW103360) The City's approach to detect and eliminate illicit discharges started with a general evaluation of the system. The evaluations consisted of dry outfall mapping (greater than 72 hours without rainfall), conducted during prolonged dry periods (typically during the summer months over the permit cycle). A complete evaluation process began by subdividing the City into sections to be Updated: September 12. 2016 14 NPDES PHASE II -- Comprehensive Stormwater Management Program Report mapped and evaluated over the course of the first permit term. The City was broken into four (4) areas which were prioritized in an order to which the area with the highest potential for iiiicit discharges was inventoried first (See Phased Outfali Inventory Area Map below). As the evaluation of each section was completed, the effort in that section moved to illicit discharge source determination. Once a discharge was detected, the property owner was notified of the corrective action required. In addition, the City utilizes a telephone and webpage hotline to field complaints by City residences. These complaints are responded to in a timely manner and are tracked by CityWorks, the City's Computerized Maintenance Management System (CMMS). The City also conducts an annual employee training event that teaches field staff how to identify potential illicit discharges and report them to the City's Stormwater Manager to initiate removal or enforcement procedures.

System wide, dry weather evaluations of storm sewer outfalls have been conducted to identify potential problem areas. Furthermore, all potential illicit discharges detected during the storm sewer system inventory were reported to the Stormwater Manager for removal or enforcement procedures. Secondly, on -site inspections have been conducted in conjunction with annual Fire Department Hazardous Materials Inspections and the annual Backflow Prevention program. 7,3.5.2. Procedures for Tracing the Source (SW103390) The City annually trains employees on illegal dumping, illicit discharge and ways to identify illicit connections. During the outfall and system inventory activities, upon discovery of a dry weather flow, the survey documents the location and attempts to follow the flow upstream and through the system to its source. The City uses several different methods to identify illicit connections including smoke testing and camera scoping, as available. Tracing suspect discharges through the storm sewer system continued through the second permit term. The City's procedures for identifying and eliminating illicit discharges can be found on file at the City. 7,3,5.3. Procedures for Removing Source (SW103400) Discovered sources have been documented and the property owner(s) have been notified of the necessary remedial measures and timeframe in which to complete them. In the case of fecal coliform discharge, the Cabarrus Health Alliance and the Rowan County Health Department has been notified. In addition, the City utilizes a telephone and webpage hotline to field complaints by City residences on potential illicit discharges. These complaints are responded to in a timely manner and are tracked by the City's Computerized Maintenance Management System (CMMS). The City's procedures for identifying and eliminating illicit discharges can be found on file at the City (Illicit Discharge Detection and Elimination (IDDE) Program Procedures Manual). 7.3.5.4. Procedures for Evaluation of the Plan (SW103410) The number of illicit discharges/connections found, violators notified, and those removed have been documented in CityWorks, 7.3.6. Non-Stormwater Discharges (SW103420) • Water line flushing: Allowable • Landscape irrigation: Allowable • Diverted stream flows: Allowable • Rising ground waters: Allowable • Uncontaminated ground water infiltration (As defined at 40 CFR §35.2005(20)): Allowable • Uncontaminated pumped ground water: Allowable • Discharges from potable water sources: Allowable • Foundation drains: Allowable • Air conditioning condensation: Allowable • Irrigation water: Allowable • Springs: Allowable • Water from crawl space pumps: Allowable • Footing drains: Allowable • Lawn watering: Allowable Updated: September 12, 2016 16 NPDES PHASE iY — Comprehensive Stormwater Management Program Report • Individual residential car washing: Allowable • Flows from riparian habitats and wetlands: Allowable • Dechlorinated swimming pool discharges: Allowable • Street wash water: Allowable T3,7 Other Incidental Non-Stormwater Discharge (SW103620) In the second permit term other incidental non-stormwater discharges were addressed. Occasional, non-commercial car washing (e.g. charity events, churches, etc.) and other non- stormwater discharges were reviewed. Limitations on the frequency of events (estimated three times per year) and location (prohibited within critical watershed areas) was considered. 718 Outreach (SW103730) A major constituent is to inform the public about the hazards of illicit discharges and illegal dumping through the methods discussed in the Public Education component. A significant focus of the Education Program is to create an awareness of the direct relationship between the MS4 and the local streams. This information has been integrated into the training program that has been developed. In the first and second permit cycle presentations about the importance of water quality were made by the City staff at various schools around the City. A more formalized plan to educate the City's school system will be developed during the third permit term. 7.3.9. Decision Process The program approach for illicit discharge detection and elimination was developed as the most effective way to meet the requirements of the measure with the amount of available funding the City had at the beginning of the first permit term. Mapping, ordinance measures, employee training and public awareness were developed first to provide a foundation for the program. After some mapping was completed and employees trained, then the detection and elimination portions of the program proceeded. Realistic expectations were used to formulate BMPs, the implementation schedule and measurable goals. The responsible person for the program is the Public Works Director delegating authorities to the Stormwater Manager. 7.3,10. Evaluation The Environmental Stewardship Commission (ESC) was created in 2008 to address the current and future need to value and protect the City's natural resources and to achieve sustainable growth. The group provides policy recommendations to City Council and works on programs and activities related to environmental stewardship. The group meets annually to review all measurable goals to determine if they are being effectively met and if the BMPs are still the best choice to attain the overall stormwater management program objective. This process will continue into the third permit cycle. Updated: September'-2, 2016 17 NPDES PHASE II — Comprehensive Stormwater Management Program Report 7.4.

Non -Structural BMPs Kannapolis Unified Development Ordinance (UDO Articles 3, 4, 9 and Appendices B, C, and D): • The Development Ordinance requires open space set -asides in certain zoning districts, mainly residential. • Ordinance has development standards for low -density and high -density projects. • Currently maintains zoning and development overlay districts to safeguard sensitive areas including watersheds and wetlands. Site design and development criteria within these districts are enhanced. • Buffer and landscape requirements are mandated for all new development. • Greenway planning is set forth in the Cabarrus County Livable Communities Blueprintand all applicable sub -division developments are required to provide adequate connections to these greenways in the form of open space set -asides. • River/Stream overlay districts have been comprised of strips of land adjacent to streams and rivers which shall be retained in their natural vegetated, re -vegetated or reforested state through the preservation of appropriate perennial vegetation. Furthermore, the City employs standards that require the construction of new roads and bridges and non-residential development to minimize built upon area, divert stormwater away from surface water supply waters as much as possible, and employ best management practices (BMPs) to minimize water quality impacts. To the extent practicable, the construction of new roads in the critical area should be avoided. The N.C. Department of Transportation BMPs as outlined in their document entitled "Best Management Practices for the Protection of Surface Waters" shall be used in all road and bridge construction projects in the Watershed Overlay Districts.

Structural BMP design is wholly adopted from the North Carolina Department of Environmental and Natural Resources (NCDENR) Manual of Stormwater Best Management Practices. Updated: September 12, 2016 22 NPDES PHASE II — Comprehensive Stormwater Management Program Report 7.5.4. Regulatory Mechanism The purpose of the City's Article 9 Environmental Control Regulations ordinance is to protect, maintain and enhance the public health, safety, environmental and general welfare by establishing minimum requirements and procedures to control the adverse effects of increased post -development stormwater runoff and nonpoint and point source pollution associated with new development and significant redevelopment as well as illicit discharges into municipal stormwater systems. This ordinance became effective on July 31, 2008 and has been reviewed by NCDENR. 7.5.5. Operation and Maintenance Section 9.4.2 of the Environmental Control Regulations requires that an Operation and Maintenance Agreement be obtained that requires the owner or owners or successors in interest to maintain, repair and, if necessary, reconstruct the structural BMP, and shall state the terms, conditions, and schedule of maintenance for the structural BMP. The current reporting, notification and enforcement mechanism was updated in the second permit cycle to more effectively provide for corrective action procedures against BMP owners in violation of set standards in the second permit term. Designated City staff members are responsible for obtaining annual maintenance inspection reports from qualified professionals, and report the number of inspections, notifications and corrective actions completed in the annual report. The program also coordinates with the Cabarrus Health Alliance and the Rowan County Health Department to assess measures to control sources of fecal coliform. 7.5.6. Decision Process In the first permit term City staff and Council -appointed members were involved in the Cabarrus Regional Technical and Stakeholder committees consisting of other municipalities, agencies, and interested parties who have worked on Phase II issues. This quorum of opinion helped to direct the City's effort toward formulating its approach to this measure. With the LIDO in place, the City reviewed the recommendations of the committees within the current framework of staffing and resources. The priority for the City was to meet the minimum program requirements by March 10, 2005, and then as the program progressed, assess the viability of moving toward the more comprehensive regional approach over the life of the program. The City will continue moving toward utilizing a more regional approach for meeting this requirement in the third permit term. Cooperative strategies between the City and both the Cabarrus Health Alliance and the Rowan County Health Department have been developed to effectively handle the issue of controlling fecal coliform bacteria. 7.5.7. Evaluation The Environmental Stewardship Commission (ESC) was created in 2008 to address the current and future need to value and protect the City's natural resources and to achieve sustainable growth.

Affected Operations (SW105770) The City of Kannapolis is under an Industrial NPDES Stormwater permit for the Department of Public Works Operation Center (NCG080698). Affected operations include: • Parks Maintenance Facility • Vehicle and Equipment Maintenance • Sewer System Maintenance • Material Storage Yard • Equipment Storage • Street Sweeping 7,6.3. Training (SW106000) Municipal employee training for various City Departments is held yearly and began during the first permit term. Particular emphasis is placed on the Public Works Department and targets street sweeping, chemical application, mowing and clearing activities, automotive fluid and chemical disposal, illicit discharge detection and elimination, etc. Informational materials available from the State are used to inform City employees about stormwater, how to report violations and good housekeeping measures for municipal operations. Training may also be available from such resources as a local or regional hazardous spill response team, or the fire department and implemented in the third permit term. 7.6.4, Maintenance and Inspections (SW106030) The City implements Standard Operating Procedures (Water Quality Protection Guidelines and Standard Operating Procedures Manual) for its facilities that cover the correct method of conducting individual operations at the facility. To reduce pollutants in the MS4, the Public Works Department provides street sweeping for all City -maintained streets. Street sweeping activities are regular, but are not scheduled. City employees clean storm sewer piping on an as needed basis, at present. The City incorporated a regular schedule of preventative maintenance operations for the system in the first permit term, The City has been performing annual inspections of City owned facilities that have the potential to negatively affect the water quality of the receiving waters. The City has performed inspections at the following City owned locations: Creek Park Fire Station 4 Safrit Park 7Baker's Dale Earnhardt Park Fire Station 5 Train Station and parkingarea Fire Department Open Space downtown Water Treatment Plant Fire Station 2 Police Station Veteran's Park Fire Station 3 Public Work Operation Center Village Park Municipal Facility Stormwater Inspection Reports for 2010 and 2011 have been developed and are kept on file at the Public Works Operation Center. Updated: September 12, 2016 26 NPDES PHASE II — Comprehensive Stormwater Management Program Report 7.6.5, Vehicular Operations (SW106170) The street sweeper is used on an as needed basis to clean all City -maintained parking lots, Salt storage areas are covered under a permanent structure. The City also employees a wash bay for cleaning all City vehicles and equipment. 7.6.6. Waste Disposal (SW106050) All waste collected from the storm sewer system is deposited in dumpsters, collected and hauled by a contracted waste disposal service to the CMS Landfill. 7.6.7. Flood Management Projects The City currently institutes development standards to prohibit building in flood -prone areas. The City's program coordinates with the Federal Emergency Management Association on flood control measures. 7.6.8. Existing Ordinances Existing ordinances and programs are subject to review by staff and City Council, 7.6.9. Decision Process The pollution prevention plan (SWPPP) for the Public Works Operation Center was developed by recognizing existing policies and practices that impact water quality and systematically addressing each individually. The deficiencies in these policies were noted and incorporated into recommendations that can be found in the Municipal Facility Stormwater Inspection Reports as mentioned in Section 7.6.4 above. Important factors considered in the recommendations were the requirement of employee training, Standard Operating Procedures (SOPS) and documenting current functions of municipal operations that have impact on water quality. 7.6.10, Evaluation The Environmental Stewardship Commission (ESC) was created in 2008 to address the current and future need to value and protect the City's natural resources and to achieve sustainable growth. The group provides policy recommendations to City Council and works on programs and activities related to environmental stewardship. The group meets annually to review all measurable goals to determine if they are being effectively met and if the BMPs are still the best choice to attain the overall stormwater management program objective. This process will continue into the third permit cycle. Updated: September 12, 2016 27 NPDES PHASE II — Comprehensive Stormwater Management Program Report 7.7.

Population Served The City of Kannapolis MS4 serves approximately 50,000 residents, all of who are permanent residents. The City has no seasonal populace. 1.2. Growth Rate Based on the decennial census data (1990 and 2000), the City of Kannapolis is increasing at an annualized rate of 2.4 percent. Growth is expected to accelerate to more than 3% per year through 2010. Population projections place the 2010 Kannapolis population at 50,087 and the 2025 population at 70,963. The estimates are very conservative in that they do not account for the potential for aggressive annexation to the east and west. 1.3. Jurisdictional and MS4 Area Served The City of Kannapolis jurisdictional area currently encompasses 35.28 square miles, of which 4.74 square miles is Extraterritorial Jurisdiction (ETJ) and 0.83 square miles is water area. The MS4 serves 30.54 square miles, which does not include the ETJ or water areas. 1.4. MS4 Conveyance System The City of Kannapolis Stormwater System consists of a combination of piping; open vegetated conveyances, and sheet flow. Per the City Unified Development Ordinance (UDO), all new city streets constructed by private developers must have curb and gutter Stormwater systems, and structural BMPs to handle stormwater runoff for developments over 20,000 square feet of impervious area are required. The system is maintained by the Streets and SW Departments, which is a function of the Public Works Department. 1.5. Land Use Composition Estimates Residential: 65% Commercial: 12% Industrial: 08% Open Space: 15% 1.6. Estimate Methodology The land use composition estimates were calculated from the City's current zoning map, then open space was estimated based on the combined areas of City maintained parks, cemeteries and greenways and water supplies. 1.7. TMDL Identification The City of Kannapolis has received no TMDL notification in the first permit cycle.

See Section 7.4. Construction Site Stormwater Runoff Control, in this report, for more information. 6.1 Name of Entity State of North Carolina, Department of Environment and Natural Resources 6.2 Measure Implemented Erosion and Sediment Control implementation and enforcement pursuant to the Sedimentation Pollution Control Act, G.S. 113A-50 et seq. 6.3 Contact Information Ed Robinette NCDENR-Mooresville Regional Office 919 N.

Public Education and Outreach on Stormwater Impacts Program Requirement: Implement a public education program to distribute educational materials to the community to conduct equivalent outreach activities about the impacts of stormwater discharges on water bodies and the steps that the public can take to reduce pollutants in stormwater runoff. 7.1.1. BMP's and Measurable Goals for Public Education and Outreach BMP Measurable Goals YR YR YR YR YR1 2 3 4 5 (a) Establish a Public Develop a public education program and Education and implement within 12 months of the permit issue X X X X X Outreach Program date.

Instead of homeowners, developing its own materials, the permittee may X X X X X and/or business rely on state -supplied Public Educational and Outreach materials, as available, when implementing its own program, (d) Public education Distribute written educational material to a broad material public audience. Possibilities include, but are not X X X X X dissemination limited to utility mail outs and special events. A# BMP's listed in the table above applied to the City's first permit cycle application. Due to the uncertainty of the contents of the second cycle permit, the same BMP's will apply for the next 5-year permit cycle until a new permit is issued to the City, 7.1.2. Target Audience For the first and second permit cycles, the target audiences for the education program include the general public (newspaper editorials), school children, Internet users and existing utility customers. These audiences were chosen because they represent a broad cross section of Kannapolis's residents, businesses and industries. School children are probably the most impressionable audience and the one most open to a message about pollution prevention. Take- home materials are also helpful since they encourage discussions between children and their parents concerning stormwater issues. Utility bill inserts are an inexpensive way to reach a large number of business and industrial clients. The Internet provides open access to all members of the public that desire more detailed information on the stormwater program. 7.1.3. Target Pollutant Sources Pollutant sources targeted in this control measure include those sources or activities that produce trash, floatables, chemicals and waste oils, fecal coliform and sediment/erosion. To address targeted sources, stormwater pollution prevention messages will be targeted to various groups. For children, the messages will focus on pollutant sources that are easy to see and understand NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina (e.g. trash, floatables). There will also be an effort toward helping children understand the nature of the storm sewer system (i.e. the water which goes down the storm drain is not treated before it enters the river). Messages targeted to industry will focus on good pollution prevention strategies and will emphasize that, through the Good Housekeeping/Pollution Prevention Minimum Control Measure, the City is acting as an example to industry. The Utility Bill Inserts will target homeowners with messages directed to proper disposal of hazardous waste and proper use of lawn and garden chemicals. Faulty septic systems and related fecal coliform problems will be included as a topic on the Stormwater microsite. 7.1.4. Outreach Program The program, as referenced in the BMP Table 7.1.1, included newspaper opinion pieces written by the City Manager or guest editorialists and presented the City viewpoint on Stormwater Management issues. This is a widely read column and is a good venue to provide the public a first look at Stormwater issues. The existing school information packet program will be expanded to include age -targeted messages related to Stormwater pollution prevention. This will include information about how children and their parents can get involved in existing Cabarrus County pollution prevention efforts (see section 7.2 for these public involvement activities). The Utility Bill inserts will present brief messages in a format with which the public is already familiar. Billings to businesses and industry may contained more detailed and targeted messages. The web microsite is a general repository for contact information and easily accessible City documents related to Stormwater. The City expected to reach about 20,000 people with some Stormwater related message over the first permit cycle. 7.1.5. Decision Process The City decided to use the methods described in Table 7.1.1 because these present the best balance between cost and effective education. The City conducted a review of all existing or anticipated education efforts and chose those that would reach a broad audience. The four BMPs chosen are all well proven methods by which the City communicates with its citizens. The measurable goals are directly related to the target audiences the City would like to reach. The responsible party for carrying out BMP 1 was the City manager since it involved a newspaper column regularly written by the City Manager. BMPs 2-4 are the responsibility of the Public Information Officer since that individual was already involved in communicating with the public via those methods. Similar BMPs are expected to be implemented by the City in the second permit cycle. 7.1.6. Evaluation The Assistant City Manager, Public Works Director, Stormwater Manager, Engineering Technician, Public Information Officer and other interested parties meet to review all measurable goals to determine if they are being effectively met and if the BMPs are still the best choice to attain the overall objective. This process will continue in the second permit cycle. 9 NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina 4) 7.2.

Due to the uncertainty of the contents of the second cycle permit, the same BMP's will apply for the next 5-year permit cycle until a new permit is issued to the City. 7.3.2. Storm Sewer System Map In order to develop a storm sewer system map the City identify City owned, operated or maintained roads, drainage easements and City owned property and traversed these areas in search of storm water discharge features. All the qualifying discharges to the "Waters of the State" (as established in the City's NPDES Permit) within these areas were identified as City Outfalls, located using a field mapping interface, and the corresponding attribute information was collected. All pipes of 12" diameter and greater and outfall channels of equivalent size were inventoried. • The City has also begun developing a system inventory map to prioritize preventative maintenance or replacement efforts, to assist with infrastructure master planning, and to track • NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina and prevent pollutants from a spill from reaching a local waterbody. It is the intent of the City to incorporate this data into its current work order management system. The City initially performed a storm water system inventory pilot project to provide the budgetary and procedural framework for a complete subsequent system inventory mapping effort. This enabled testing of the database design and work procedures. In addition, the City can now better project costs and resources needed to complete the full storm sewer system inventory. The City selected a pilot area that had the highest potential to contain potential illicit discharges. Consequently, this area was determined to be in the most urbanized and oldest part of the City which has the most potential for a compromised storm sewer system. The system inventory process consisted of mapping all storm water drainage point features, collecting all appropriate corresponding attribute data, and generating a model of the linear drainage network by also mapping all linear drainage features and collecting associated attribute data. The resulting dataset is a closed topological network with embedded relationships between the point features that collect storm water runoff and the linear features that convey the runoff from one feature to another and ultimately to the aforementioned "Waters of the State". As funding becomes available as the second permit term proceeds, the City will consider mapping other portions of the MS4, as well. The City also integrates the mapping effort into a Geographic Information System (GIS). 7.3.3. Regulatory Mechanism In the first permit term, the City developed a Stormwater Management Ordinance enabling this and other Stormwater management program initiatives. The mechanism provides for definition and prohibition of illicit non-stormwater discharges, and inspection for and elimination of such discharges. The ordinance came into effect on X/XX/XXXX. 7.3.4. Enforcement The ordinance provides for enforcement actions to be taken for illicit discharge violations, including levying penalties against offenders and providing compensatory measures to the City should intervention and removal of the discharge become necessary. The enforcement methodology involves notification of the property owner, establishing a reasonable timeframe in which to address the occurrence, and issuance of notices of violation and fines. 7.3.5. Detection and Elimination The City's approach to detect and eliminate illicit discharges started with a general evaluation of the system. The evaluations consisted of dry outfall mapping (greater than 72 hours without rainfall), conducted during prolonged dry periods (typically during the summer months over the permit cycle). A complete evaluation process began by subdividing the City into sections to be mapped and evaluated over the course of the first permit term. The City was broken into four (4) areas which were prioritized in an order where the area with the highest potential for illicit discharges was inventoried first. As the evaluation of each section was completed, the effort in that section moved to illicit discharge source determination. Once a discharge was detected, the property owner was notified of the corrective action required. In addition, the City utilizes a telephone and webpage hotline to record complaints by City residences. These complaints are responded to in a timely manner and are tracked by the City's Computerized Maintenance Management System (CMMS). 12 NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina OThe City also conducts an annual employee training event that teaches field staff how to identify potential illicit discharges and report them to the City's Stormwater Manager to initiate removal or enforcement procedures. 7.3.5.1. Procedures for Locating Priority Areas The aging infrastructure that centers on the Canon Mill Village is a location of interest to the City, as this portion of the system is very old and likely contains a number of illicit connections. System wide, dry weather evaluations of storm sewer outfalls have been conducted to identify potential problem areas. See Section 7.3.5 Detection and Elimination for more information. Furthermore, all potential illicit discharges detected during the storm sewer system inventory were reported to the Stormwater Manager for removal or enforcement procedures. Secondly, on -site inspections have been conducted in conjunction with annual Fire Department Hazardous Materials Inspections or the annual Backfiow Prevention program. 7.3.5.2. Procedures for Tracing the Source The City annually trains employees on illegal dumping, illicit discharge and ways to identify illicit connections. During the outfall and system inventory activities, upon discovery of a dry weather flow, the survey documents the location and attempts to follow the flow upstream and through the system to its source. The City uses several different methods to identify illicit connections including smoke testing and camera scooping, as available. Tracing suspect discharges through the storm sewer system will continue through the second permit term. 7.3.5.3. Procedures for Removing Source Discovered sources have been documented and the property owner(s) have been notified of the necessary remedial measures and timeframe in which to complete them. In the case of fecal coliform discharge, the Cabarrus Health Alliance and the Rowan County Health Department has been notified. 7.3.5.4. Procedures for Evaluation of the Plan The number of illicit discharges/connections found and notified, and the number of those removed have been documented. 7.3.6. Non-Stormwater Discharges • Water line flushing: Allowable • Landscape irrigation: Allowable • Diverted stream flows: Allowable • Rising ground waters: Allowable • Uncontaminated ground water infiltration (as defined at 40 CFR §35.2005(20)): Allowable • Uncontaminated pumped ground water: Allowable • Discharges from potable water sources: Allowable • Foundation drains: Allowable • Air conditioning condensation: Allowable • Irrigation water: Allowable • Springs: Allowable eWater from crawl space pumps: Allowable • Footing drains: Allowable 13 NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina • Lawn watering: Allowable • Individual residential car washing: Allowable • Flows from riparian habitats and wetlands: Allowable • Dechlorinated swimming pool discharges: Allowable • Street wash water: Allowable 7.3.7 Other Incidental Nan-Stormwater Discharge In the second permit term other incidental non-stormwater discharges will be addressed. Occasional, non-commercial car washing (e.g. charity events, churches, etc.) and other non- stormwater discharges will be reviewed. Limitations on the frequency of events (estimated three times per year) and location (prohibited within critical watershed areas) will be considered. 7.3.8 Outreach A major constituent is to inform the public about the hazards of illicit discharges and illegal dumping through the methods discussed in the Public Education component. A significant focus of the Education Program is to create an awareness of the direct relationship between the MS4 and the local streams. This information has been integrated into the training program that has been developed. In the first permit cycle presentations about the importance of water quality were made by the City staff at various schools around the City. A more formalized plan to educate the City's school system will be developed during the second permit term. 7.3.9. Decision Process The program approach for illicit discharge detection and elimination was developed as the most effective way to meet the requirements of the measure with the amount of available funding the City had at the beginning of the first permit term. Mapping, ordinance measures, employee training and public awareness were developed first to provide a foundation for the program. After some mapping was completed and employees trained, then the detection and elimination portions of the program proceeded. Realistic expectations were used to formulate BMPs, the implementation schedule and measurable goals. The responsible person for the program is the Public Works Director delegating authorities to the Stormwater Manager. 7.3.10. Evaluation The Assistant City Manager, Public Works Director, Stormwater Manager, Engineering Technician, Public Information Officer and other interested parties meet to review all measurable goals to determine if they are being effectively met and if the BMPs are still the best choice to attain the overall objective. This process will continue in the second permit cycle. Upon an evaluation, in the second permit term, it may be necessary to revise the illicit discharge ordinance in order to improve the City's efficiency in identifying and removing illicit discharges. 14 NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina 0 7.4. Construction Site Stormwater Runoff Control n U U 7.4.1. Regulatory Mechanism The City of Kannapolis will relies on the NC Department of Environment and Natural Resources Sediment and Erosion Control Program and DWQ general stormwater permit, along with the North Carolina General Construction Permit for its construction activities to meet this requirement. More specifically, the City has entered into an agreement with Cabarrus County on August 23, 2004 (Resolution #2004-37, see Attachment 1) that requires Cabarrus County to provide enforcement of the Soil Erosion and Sedimentation Control Ordinance within the corporate limits of the City. 15 NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina 7.5. Post -Construction Stormwater Management in New Development and Redevelopment Program Requirements: The objectives of the program are to: Manage stormwater runoff from new development / redevelopment that drains to the MS4 and disturbs an acre or more of land surface, including projects less than an acre that are part of a larger common plan of development or sale.

Non -Structural BMPs Kannapolis Unified Development Ordinance (UDO Articles 3, 4, 9 and Appendices B, C, D): • The Development Ordinance requires open space set -asides in certain zoning districts, mainly residential. • Currently maintains zoning and development overlay districts to safeguard sensitive areas including watersheds and wetlands. Site design and development criteria within these districts are enhanced. • Buffer and landscape requirements are mandated for all new development. • Greenway planning is set forth in the Cabarrus County Livable Communities Blueprint and all applicable sub -division developments are required to provide adequate connections to these greenways in the form of open space set -asides. 16 NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina • A 30 foot undisturbed buffer plus no less than an additional 20 foot structural setback is currently required for perennial streams. 7.5.3. Structural BMPs The UDO currently prescribes development that exceeds 20,000 square feet of impervious coverage to control and treat the stormwater runoff volume leaving the project site generated by a one (1) inch rain event. Runoff volume drawdown time shall be a minimum of 48 hours, but not more than 120 hours. Volumes to be detained must comply with the methods listed in the NCDERN Stormwater Best Management Practices Manual. All structural stormwater treatment systems used to meet the requirements of the program shall be designed to have a minimum of 85% average annual removal for Total Suspended Solids (TSS). Furthermore, detention facilities shall be designed to maintain the predeveloped runoff rate from the 1-year and 10-year, 24 hour design storm events. 7.5.4. Regulatory Mechanism The purpose of the City's Article 9 Environmental Control Regulations ordinance is to protect, maintain and enhance the public health, safety, environmental and general welfare by establishing minimum requirements and procedures to control the adverse effects of increased post -development stormwater runoff and nonpoint and point source pollution associated with new development and significant redevelopment as well as illicit discharges into municipal stormwater systems. This ordinance became effective on July 31, 2008 and has been reviewed by NCDENR. • 7.5.5.Operation and Maintenance Section 9.4.2 of the Environmental Control Regulations requires that an Operation and Maintenance Agreement be obtained that requires the owner or owners or successors in interest to maintain, repair and, if necessary, reconstruct the structural BMP, and shall state the terms, conditions, and schedule of maintenance for the structural BMP. The current reporting, notification and enforcement mechanism may be updated to more effectively provide for corrective action procedures against BMP owners in violation of set standards in the second permit term. Designated City staff members will be responsible for obtaining annual maintenance inspection reports from qualified professionals, and will report the number of inspections, notifications and corrective actions completed in the annual report. The program also coordinates with the Cabarrus Health Alliance and the Rowan County Health Department to assess measures to control sources of fecal coliform. 7.5.6. Decision Process In the first permit term City staff and Council -appointed members were involved in the Cabarrus Regional Technical and Stakeholder committees consisting of other municipalities, agencies, and interested parties who have worked on Phase II issues. This quorum of opinion helped to direct the City's effort toward formulating its approach to this measure. With the UDO in place, the City reviewed the recommendations of the committees within the current framework of staffing and resources. The priority for the City was to meet the minimum program requirements by March 10, 2005, and then as the program progressed, assess the viability of moving toward the more • comprehensive regional approach over the life of the program. The City will continue moving 17 0 • NPDES PHASE U — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina toward utilizing a more regional approach for meeting this requirement in the second permit term. Cooperative strategies between the City and both the Cabarrus Health Alliance and the Rowan County Health Department have been developed to effectively handle the issue of controlling fecal coliform bacteria. 7.5.7. Evaluation The Assistant City Manager, Public Works Director, Stormwater Manager, Engineering Technician, Public Information Officer and other interested parties meet to review all measurable goals to determine if they are being effectively met and if the BMPs are still the best choice to attain the overall objective. This process will continue in the second permit cycle. 18 NPDES PHASE II — Comprehensive Stormwater Management Program Report City of Kannapolis, North Carolina ® 7.6.

GENERAL See.11-1. Title. This Ordinance shall be and is collectively referred to and cued as "The Storm Water Utility, Control and Management Ordinance of Kannapolis, North Carolina." Sec. I-2. Purposes and findings. The purpose of this Ordinance is to protect and promote the public health, safety, and welfare by preventing the introduction of potentially harmful materials into the City storm sewer system; to protect property from potential storm water damage; to maintain and enhance water quality, and to meet the requirements of the National Pollutant Discharge Elimination System for Storm Water Discharges The City Council appointed a group of citizens and representatives of the major landholders and generators of storm water runoff known as the "Storm Water Stakeholder's Advisory Committee" to evaluate the city's current storm water program and to make recommendations to the City Council about the future level of service the City should provide in regard to storm water. Based on the recommendations of the sakeholder's advisory committee and information provided by a consultant chosen by the City, the City Council of the City of Kaanapolis makes the following findings (1) Storm water poses a serious threat to the public health, safety, and welfare. This threat cannot be eliminated entirely. Factors affecting this threat which are beyond the City's control include- frequency and intensity of precipitation, the topography in and around the City; the types of soils and -other geologic structures found in and around the City, body of law established under state and federal authority concerning water rights generally and including but not limited to navigable and non -navigable waters, surface waters, and underground waters; unauthorized interference with the City's storm water drainage system; and the amount of impervious surfaces associated with a reasonable level of development. (2) The management of storm water can reduce this threat through. a Constructing, operating, and maintaining needed facilities, and b Regulating and controlling the use and development of land to reduce the adverse effects of storm water. (3) In order to provide an effective and long-term approach to storm water management, an adequate funding source must be identified Equitable funding is provided by a system of charges that is related to the volume and quality of storm water runoff from developed 40 land. (4) Based on various studies conducted either by the City of Kannapolis, or on its behalf, it is estimated that the City of Kannapolis has a large backlog of storm water services, maintenance, and capital improvements required to meet basic flood control, stream stabilization and water quality objectives and the level of service recommended by the "Storm Water Stakeholders Advisory Committee " Sec.
