The following nine (9) Mecklenburg County Phase II jurisdictions/entities are covered by this SWMP: 1. Mecklenburg County (unincorporated) 2. Charlotte -Mecklenburg Schools (CMS) 3. Central Piedmont Community College (CPCC) 4. Town of Cornelius 5. Town of Davidson 6. Town of Huntersville 7. Town of Matthews 8. Town of Mint Hill 9. Town of Pineville This SWMP identifies the specific elements and minimum measures that the Mecklenburg County Phase II jurisdictions/entities will develop, implement, enforce, evaluate and report to the North Carolina Department of Environmental Quality (NCDEQ) Division of Energy, Minerals and Land Resources (DEMLR) in order to comply with the MS4 Permit number NCS000395 as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the Mecklenburg County Phase II jurisdictions/entities and located within the corporate limits or areas under their control. This SWMP also includes in Section 11 the Water Quality Recovery Program developed for compliance with the Permit requirement for reducing levels of the pollutant of concern in accordance with approved Waste Load Allocation assigned to stormwater in an approved TMDL. In preparing this SWMP, the Mecklenburg County Phase II jurisdictions/entities have evaluated their MS4s and the Permit requirements to develop a comprehensive 5-year SWMP that will meet the community's needs, address local water quality issues and provide the minimum measures necessary to comply with the Permit. The SWMP will be evaluated and updated annually to ensure that the elements and minimum measures it contains continue to adequately provide for Permit compliance and the community's needs. Once the SWMP is approved by NCDEQ, all provisions contained and referenced in this SWMP, along with any approved modifications of the SWMP, are incorporated by reference into the Permit and become enforceable Sections of the Permit. Any major changes to the approved SWMP will require resubmittal and approval by NCDEQ and may require a new public comment period depending on the nature of the changes.

Additional definitions are provided on page vi of the Table of Contents. • Stream Index / AU Number: NCDEQ identifies waters by index numbers and assessment unit numbers (AU#) that are used to track defined stream segments or waterbodies. • Water Quality Classification (Class): Designations applied to surface water bodies by NCDEQ that define the best uses to be protected within these waters as required by the Clean Water Act, including water supply use (WS), recreation activities (B), and aquatic life (C). • Criteria: Numeric and narrative criteria that establish levels that will ensure the protection of the designated best use or classification of the water body. Also referred to as a water quality standard. • TMDL: Acronym for Total Maximum Daily Load. A TMDL is the calculation of the maximum amount of a pollutant allowed to enter a waterbody so that the waterbody will meet and continue to meet water quality standards for that particular pollutant. A TMDL identifies pollutant reduction targets and allocates load reductions necessary to the source(s) of the pollutant to restore waterbodies where water quality criteria are exceeded. 3.4 MS4 Interconnections The MS4s in Mecklenburg County are interconnected and directly exchange stormwater flow along with the NCDOT MS4. The Phase II MS4 maps do not show the locations of these interconnections. 3.5 Total Maximum Daily Loads (TMDLs) All surface waters with approved TMDLs in Mecklenburg County flow through both Phase I and Phase II jurisdictions except for Goose Creek and the Rocky River, which lie entirely in Phase II. To ensure effective coordination, the City of Charlotte, which holds a Phase I Permit, and Mecklenburg County and the Towns, which hold a joint Phase II Permit, have agreed that the City of Charlotte will serve as the lead jurisdiction for compliance with TMDL requirements when the majority of the TMDL watershed lies within the Phase I jurisdiction. When most of the 10 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services watershed lies within Phase II, Mecklenburg County will serve as the lead. The lead jurisdiction is responsible for coordinating and implementing all required TMDL compliance efforts and submitting all the required plans and reports to the State. They are also responsible for coordinating with the other jurisdictions as necessary to implement compliance efforts. Table 4 identifies the receiving waters for MS4 discharges in Mecklenburg County that have a TMDL approved by EPA. The table also indicates the jurisdiction responsible for compliance with TMDL requirements. The source of the data for Table 4 is NCDEQ's Water Resources website located at: NCDEQ Modeling & Assessment Unit web page. Figure 3 shows the locations of these receiving waters in relation to the Phase I and Phase II jurisdictions in Mecklenburg County.

The City of Charlotte and Mecklenburg County have developed and are currently implementing strategies and tailored BMPs within the scope of the six (6) minimum Permit measures for the TMDL watersheds identified in Table 4 that have a waste load allocation (WLA) assigned to stormwater. The purpose of these initiatives, which are incorporated into a TMDL Water Quality Recovery Program (WQRP), is to reduce levels of the pollutant of concern to the MEP in accordance with approved Waste Load Allocation (WLAs) assigned to stormwater in the approved TMDL. Section 11 of this document includes the WQRP for those waters where Mecklenburg County is the lead, including portions of the Rocky River, Lake Wylie and Goose Creek. The implementation of the BMPs included in this Program are ongoing. Table 5 describes the activities implemented by Mecklenburg County when new TMDLs are approved for waters within the Phase II jurisdiction. No new TMDLs have been developed for Mecklenburg County since 2014; therefore, all Mecklenburg County TMDLs have been in effect more than 36 months and all the requirements in Table 5 will apply. These requirements are currently being met for all existing TMDLs. The City of Charlotte develops and implements BMPs for those waters where they are the lead through the implementation of their Phase I Permit, which includes portions of Irwin, Long, Little Sugar, McAlpine, Sugar, Steele, and McKee Creeks. Information regarding these BMPs is included in Charlotte's NPDES MS4 12 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services TMDL Watershed Plan, which is available through their Phase I contact. These BMPs are applied within the Phase I jurisdiction of the watershed. For the Phase II jurisdictions, the BMPs described in Section 11 of this document are applied. Table 5: New TMDL Requirements Requirement Schedule 1. Submit a TMDL annual report to NCDEQ including a description of existing programs, 12 months of the controls, partnerships, projects, and strategies to address impaired waters and a brief final EPA approval explanation as to how the programs, controls, partnerships, projects and strategies of a TMDL address impaired waters. 2. Submit a TMDL annual report to NCDEQ including an assessment of whether additional 24 months of the structural and/or non-structural BMPs are necessary to address impaired waters and a final EPA approval brief explanation as to how the programs, controls, partnerships, projects and strategies of a TMDL address impaired waters. 3. Submit a TMDL annual report to NCDEQ including a description of activities expected 36 months of the to occur and when the activities are expected to occur. final EPA approval of a TMDL As stated in the Permit, if subject to an approved TMDL, the Permittee is in compliance with the TMDL if the permittee complies with the conditions of the Permit, including developing and implementing appropriate BMPs to reduce non -point source pollutant loading to the MEP. While improved water quality is the expected outcome, the NPDES MS4 Permit obligation is to reduce non -point source pollutant loading to the MEP. The MS4 Permittee is not responsible for attaining the water quality standards (WQS) at the ambient monitoring stations. NCDEQ expects attaining the WQS will only be achieved through reduction from the MS4, along with reductions from other nonpoint source contributors. In January 2022, the State issued its Draft 2022 303(d) list and integrated 305(b) and 303(d) reports. Charlotte -Mecklenburg Storm Water Services (CMSWS) reviewed these reports and determined that no new TMDLs have been approved in Mecklenburg County. Since no new TMDLs have been approved, no changes will be made to the existing Water Quality Recovery Programs and Strategies. 13 11-022) Charlotte -Mecklenburg STORM NPDES # NCS000395 — November 2022 WATER Stormwater Quality Management Program Plan Services 11-137b 11-IN-10 11-W-Up -9b 11-1 1 17-C L .

These evaluations were based on responses to service requests, results from water quality monitoring and other general water quality program activities. The unpermitted, non-stormwater flows listed as incidental in Table 8 have been determined based on this evaluation to be insignificant contributors of pollutants to the MS4; therefore, according to Part I paragraph H 2 of NPDES Permit No. NCS000395 these discharges are authorized through the MS4s of the co-permittees. The street washing discharges included in Table 8 are addressed in more detail under Section 10.7 of this SWMP. Based on the evaluation, individual residential (noncommercial) car washing was determined to be incidental with no significant impact to water quality provided washing activities do not occur at designated vehicle wash areas that are connected, directly or indirectly to the stormwater system or surface waters as is sometimes observed at multi -family residential complexes. With regard to charity car washing, the evaluation revealed no significant negative water quality impacts provided washing is not performed by the same organization or at the same location on a routine basis (more than one time in a thirty -day period). The key to the designation of these car washing activities as incidental with no significant impact to water quality is that they are all noncommercial in nature and occur infrequently over a dispersed area. Car washing activities other than those described above are identified as having significant impacts to water quality and are prohibited by local surface water pollution control ordinances. These pollutants are primarily addressed through responses to requests for service and investigations associated with the Illicit Discharge Elimination Program (IDEP) as described in Sections 7.7.1.1 and 7.7.2.1 of this document, respectively. NCDEQ has not required that non- 17 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services stormwater flows other than those listed in Table 8 be specifically controlled by the Mecklenburg County Phase II jurisdictions/ entities. These other non-stormwater flows are considered a significant impact to water quality and are addressed through the implementation of the programs described in this SWMP.

General data and information obtained from water quality monitoring and inspection activities as well as responses to service requests were considered in the development of this table. These same considerations are made each year when this table is evaluated and modified as necessary as part of the annual review process for the SWMP. Although additional pollutants not in this table are sometimes targeted by the public education program, the pollutants in this table are considered the primary target pollutants. A more detailed description of the targeted audiences and why they were selected is provided in Section 3.10. Additional detail regarding the Public Education and Outreach Program is provided in a document referred to as the "Umbrella" Plan developed and implemented by CMSWS to coordinate public education efforts between the Phase I and Phase II jurisdictions in Mecklenburg County. The Umbrella Plan is updated regularly to meet the changing needs of the community. A copy of this plan is available upon request to the Environmental Manager for Mecklenburg County's Water Quality Program.

These audiences were targeted based on their ability to impact the issues contributing to the likely pollutant sources described in Table 9. In addition, the targeted audiences were selected based on their potential for expanding our volunteer programs for protecting and restoring water quality conditions. Residential Communities: This group has the ability to positively impact both targeted pollutants identified in Table 9 above. They also have a significant potential to increase participation in volunteer programs for protecting and restoring water quality conditions. This is a large, targeted audience composed of many subsets, including but not limited to homeowners, renters, multi -family communities, pet owners, etc. CMSWS has developed educational materials for reaching residential groups and will develop and implement outreach initiatives on an as needed basis to address specific water quality issues as they arise. Commercial: This group, like the residential group, has a significant potential to positively impact water quality and has several subsets, including landscapers, grading contractors, construction industry, building maintenance companies, mobile washers, automotive repair shops, etc. CMSWS has developed educational messages for reaching these subsets and will develop and implement outreach initiatives on an as needed basis to address specific water quality issues as they arise. 19 Chaloffe STORM WATER services SECTION 4 Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 STORMWATER MANAGEMENT PROGRAM ADMINISTRATION A program has been developed and is currently being implemented for administering the Phase II Permit for Mecklenburg County's Phase II jurisdictions/entities for the purpose of ensuring that all Permit requirements are effectively and efficiently fulfilled by co-permittees in accordance with the SWMP and that the administration requirements specified in the Permit are being met. The program is administered by CMSWS's Water Quality Program as described in the following Sections. 4.1 Program Goal The goal of Program Administration is to implement, manage and oversee the provisions of the SWMP to control to the maximum extent practical the discharge of pollutants from the municipal storm sewer system associated with stormwater runoff and illicit discharges, including spills and illegal dumping and to ensure that all Phase II Permit requirements are effectively and efficiently fulfilled. 4.2 BMP Summary Table CMSWS will manage and report the BMPs described in Table 10 for the administration of the SWMP.

The Environmental Manager reports to the Director of CMSWS who serves as the Stormwater Program Administrator as delegated by the Mecklenburg County Board of Commissioners by a resolution dated December 17, 2002. Five (5) Environmental Supervisors that report to the Environmental Manager are responsible for implementing five (5) of the seven (7) components of the SWMP. An Environmental Supervisor and Lead Project Manager in the Permitting and Compliance Program who reports to a Senior Project Manager who reports to the Director of CMSWS are responsible for implementing the other two (2) components of the SWMP. In most cases, staff under the direction of their Environmental Supervisor are responsible for completing the activities necessary for implementing the components of the SWMP. Table 11 illustrates the breakdown of responsibilities. Appendix A provides additional information regarding these responsibilities, including BMPs and measurable goals. Appendix B provides an organizational chart that shows where the responsible parties fit into the structure of CMSWS. The procedures, specific tasks, deadlines and assigned staff for fulfillment of the SWMP are described in an annual Work Plan. A copy of this Work Plan is available upon request to the CMSWS's Environmental Manager for Mecklenburg County's Water Quality Program. Each co-permittee is responsible for compliance with Permit requirements for the operation and maintenance of facilities, MS4s, stormwater control measures (SCMs), streets, and parking lots that they own and/or maintain.

Kevin Fox, Public Works Director, is the responsible party for the Town of Huntersville (see Table 16 for contact information). CMSWS serves as the administrator of Huntersville's Post -Construction Ordinance. (2) CMSWS is responsible for implementing the BMPs described in the summary tables contained in this document unless otherwise indicated as well as coordinating with County staff regarding operation and maintenance of County owned facilities and operations. Co-permittees are responsible for Permit compliance at the facilities that they own and/or operate with guidance from CMSWS. Table 16 provides the contact names for the responsible co-permittees. 23 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 4.4 Standard Operating Procedures (SOPS) Written Standard Operating Procedures (SOPS) and Standard Administrative Procedures (SAPS) are developed to identify specific action steps, schedules, resources, and responsibilities for implementing the six (6) minimum measures for controlling pollution sources. Written procedures can be free standing, or where appropriate, integrated into the SWMP. They adhere to a standard format and include an approval page and revision history. SOPS are also available for inclusion in SWPPPs for facilities and are made available to staff for dissemination as appropriate for vehicle washing, fueling, etc. These SOPS also follow a standard format but do not typically include an approval page or revision history. 4.5 Documentation The following summarizes CMSWS's documentation of Phase II Permit compliance activities. 1. The specific actions and deadlines implemented by CMSWS in the execution of the BMPs and measurable goals for compliance with Permit requirements is maintained in an annual Work Plan. 2. Annual Work Plans are maintained in a database referred to as Time Pro. Time Pro is also used to track staff time toward completion of Work Plan assignments. 3. The Cityworks database maintains documentation of the completion of Work Plan activities except for water quality monitoring activities that are documented in the Water Quality Database. 4. The LAN folder at \\hmcfs0l\attachments\WQ serves as the backup destination for Cityworks documentation generated by the Water Quality Program. 5. The LAN folder at G:\Water Quality\WQ Xfer\WQ\Phase II Permit maintains annual reports, co-permittee information, Permit applications, Permit audits, Phase II Permits, presentations, State correspondence, SWMPs, TMDL documentation, and other information relating to the Phase II Permit. 6. The Environmental Data Management System (EDMS) serves as the reporting mechanism for data relating to services requests and notices of violation, including repeat offenders as required by the Permit. 7. The Emerald System maintains documentation of stormwater drainage service requests. 8. The Electronic Plan Review (EPM) system maintains documentation of plan and plat reviews for compliance with Erosion Control and Post -Construction Programs. 9. Co-permittees are responsible for maintaining documentation for compliance activities that are their responsibility as described in Appendix F. CMSWS's staff are required to documentation all activities performed for compliance with Phase II Permit requirements as summarized above. The annual Work Plan maintained in Time Pro informs staff of their assigned activities and deadlines and provides them with tools for tracking the completion of assignments. It is the responsibility of the lead staff for each activity as identified in the Work Plan to complete the necessary documentation. Procedures have been developed for the proper completion of this documentation and are available to staff in the Water Quality Program Policies and Procedure Manual. Cityworks is the primary mechanism used to document the completion of Work Plan activities except for water quality monitoring activities, which are documented in the Water Quality Database. The Cityworks Server Attachments folder 24 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan —NPDES # NCS000395 —November 2022 WATER services on the LAN at \\hmcfs0 I \attachments\WQ that corresponds to the current fiscal year is the back- up destination for most documentation. The Activity Report in Cityworks is used for maintaining documentation for most activities. Some of these activities have templates in Cityworks for more effective documentation, including responses to service requests, issuance of notices of violation and various routine inspections (i.e., erosion control, industrial and municipal facilities and BMPs). CMSWS's staff are required to provide the information described below for all completed activities. A template in Word format is used by staff to capture this information. • Specific date(s) when work was performed. • Names of individual(s) that performed the work. • Description of the work that was performed. • Description of how the work was performed. • Locations/areas where the work was performed. • Persons or groups contacted for completion of the work. • Description of all compliance activities, including notices of violation issued, fines, etc. • Specific outcomes resulting from the completion of the assigned task. 4.6 Annual Assessments of SWMP and Implementation of Improvements Three (3) separate annual assessment occur at different times during the fiscal year as follows: 1. In August of every year, an annual report is submitted to the State in the format they provide. 2. In October of every year, a written annual assessment is performed of the BMPs included in the SWMP by supervisors and lead staff working with the program manager. Meetings and other efforts are conducted as necessary to maximize the effectiveness of the assessment that at a minimum includes the following: • Description of activities performed for compliance with the SWMP as described in the annual Work Plan. • Summary of data and information collected as a result of these activities throughout the year along with an assessment of what the data indicates in light of the SWMP. • Description of program evaluations completed and results, including whether program components and BMPs specified in the Storm Water Plan were effectively and efficiently fulfilled toward achieving program goals and whether permit requirements were met or exceeded. • Assessment of progress toward achieving measurable goals and identified measures of success. • Status of implementation of the SWMP and whether NPDES Permit requirements have been fulfilled. • Status of implementation of Water Quality Recovery Programs for approved TMDLs. • Proposed changes to the SWMP. • Improvements identified to improve individual program effectiveness, including the desired result, responsible staff, and time frame for implementation. Improvements are incorporated into annual Work Plans for implementation. 25 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services • Status of implementation of improvements identified in the previous annual assessment. 3. In November of every year, an assessment is completed of the SWMP document that includes the following: • Incorporation of the proposed changes from the completion of the annual assessment the previous month as described in #2 above. • Documentation of any necessary changes to programs or practices. • Assessment of compliance with the Permit requirements The three (3) above -described assessments are submitted to DEQ annually upon completion. In addition, the assessments result in the identification of improvements/modifications to specific work activities that are considered by lead staff, supervisors, and the program manager. The annual Work Plans contained in Time Pro are modified as agreed upon to incorporate these improvements/modifications into day-to-day work activities. The annual Work Plans in Time Pro contain additional detail and more finite deadlines compared to what is provided in the SWMP. The FY2023 assessment of the BMPs included in the SWMP was completed in October 2022 by supervisors and lead staff working with the program manager. The list of improvements incorporated into the annual Work Plans contained in Time Pro as a result of this assessment are provided in Table 12 below. The FY2023 assessment of the SWMP document was completed in November 2022 by supervisors and lead staff working with the program manager. Changes made to the SWMP document to improve its overall effectiveness are described in Table 13 below. Assessments of the SWMP document completed for previous fiscal years is provided in Table 1.

The Permit further specifies that the State can administer and enforce the Permit requirements with respect to individual co-permittees found in non-compliance with the Permit. The Stormwater Management Program Interlocal Agreements entered into between Mecklenburg County and all the co-permittees provides further clarification by stating that each co-permittee is responsible for taking the actions necessary within their respective jurisdictions/ entities as described by CMSWS staff to ensure compliance with Permit requirements. For example, CMSWS staff is responsible for inspecting municipal facilities under the Pollution 32 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Prevention and Good Housekeeping Program and providing written notification to the responsible jurisdiction/entity regarding inspection results, including all deficiencies. The jurisdiction/entity and not CMSWS is responsible for implementing the actions necessary to correct all deficiencies. Each co-permittee is responsible for performing all activities related to the maintenance and repair of their property and infrastructure for compliance with Permit requirements, including facility maintenance as well as inlet, pipe, parking lot, and street cleaning. A list of co-permittee responsibilities for Phase II Permit compliance is provided in Appendix F. A description of co-permittee responsibilities for each Permit requirement is also provided in Appendix A 4.10 Coordination Between Co-Permittees Proper coordination between all co-permittees is essential for ensuring success at fulfilling Permit requirements. CMSWS undertakes specific actions for proper coordination as described below. 1. A Funding Strategy is developed by CMSWS describing the methodology to be used to equitably share costs associated with compliance with Phase II Permit requirements. 2. By April 30th of every year, CMSWS prepares a draft Work Plan and submits to all co- permittees for review and comment. This Work Plan describes what activities CMSWS will perform during the next fiscal year to comply with Permit requirements and includes a list of co-permittee responsibilities as described in Appendix F. The Work Plan also includes a budget for each co-permittee based on the Funding Strategy developed in #1 above. Comments are received and addressed, and a final, approved Work Plan is completed and distributed to all co-permittees by June 30 of every year. 3. Quarterly reports are submitted to all co-permittees (referred to as Statements) listing the activities performed for Permit compliance, time involved and associated costs. 4. Meetings are held with co-permittees as necessary, which are oftentimes virtual, to provide updates regarding Work Plan implementation and Permit compliance as well as to give co-permittees an opportunity to ask questions. 5. Inspections are conducted annually at the public works facilities owned and operated by the co-permittees to ensure compliance with Permit requirements. As part of these inspections, information is obtained from the co-permittees regarding the activities being performed for MS4 operation and maintenance as well as street and parking lot cleaning. Annual inspections are also performed by CMSWS of SCMs owned and/or operated by co-permittees for compliance with post -construction ordinance requirements. The co- permittee is also made of their responsibilities for Phase II Permit compliance, and a copy of Appendix F is provided. 6. By November 30th of every year, a detailed annual report is provided to all co-permittees describing the specific Permit compliance activities completed and a status of the measures of success. 33 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services SECTION 5: PUBLIC EDUCATION AND OUTREACH PROGRAM A Public Education and Outreach Program has been developed and is currently being implemented for Mecklenburg County's Phase II jurisdictions/entities to inform the community of the physical attributes of stormwater runoff, including the pollutants typically contained in runoff and their likely sources, as well as the impacts of these pollutants on surface water quality. The Program also describes the steps that the public can take to reduce pollutants in stormwater runoff and protect water quality. The program is administered by CMSWS's Water Quality Program as described in the following Sections. 5.1 Program Goals and Objectives CMSWS's establishes its goals and objectives for its Public Education and Outreach Program, which are evaluated and updated annually as necessary, based on the actions necessary to effectively address the targeted pollutants and pollutant sources identified in Table 9. The current goals of the Public Education and Outreach Program are as follows: 1. Change public behaviors to reduce sources of water pollution and improve water quality. 2. Promote participation in activities aimed at restoring water quality conditions. The current objectives of the Public Education and Outreach Program are as follows: a. Develop, distribute and advertise public educational and outreach messages to the community and conduct outreach activities to inform the public of the negative impacts that stormwater discharges have on water quality by promoting the following concepts: • All storm drains flow directly to creeks and lakes without treatment. • Storm drains are only for rain. • Anything other than rain that enters a storm drain becomes stormwater pollution. • Buffers around lakes and streams act to filter pollutants and are important for protecting water quality. b. Develop, distribute and advertise public educational and outreach messages to inform the public of the steps they can take to reduce the negative impacts from stormwater discharges and restore water quality conditions by promoting the following concepts: • Do not pour anything down a storm drain or in a creek or lake. • Volunteer to mark storm drains, adopt streams and participate in the annual Big Spring Clean event. • Report pollution to 311. • Maintain a vegetated buffer around lakes and streams. 5.2 BMP Summary Table Table 16 describes the BMPs implemented as part of the Public Education and Outreach Program.

This stormwater helpline receives citizen requests for service that are forwarded to CMSWS for response, provides general water quality information, and promotes public involvement and participation through established volunteer programs. To ensure effectiveness, CMSWS has provided the staff at 311 with a "key word" index that is used to trigger select responses to water quality related questions and requests. These key words are reviewed and updated annually as necessary and provided to 311 for implementation. For example, if a caller uses the key word "Stream Cleanup" 311 staff has been provided with a select response that refers the caller to the appropriate staff contact at CMSWS for more information. Various media, including television, radio, print ads, brochures, social media, etc., are used to promote 311 as the number to contact to report suspected pollution problems and sign-up for volunteer programs. 311 has been in use since September 8, 2008 and has proven to be an effective helpline service, resulting in CMSWS receiving an average of over 100 reports of potential water quality problems annually in the Phase II jurisdictions and an additional 600 reports in Charlotte's Phase I jurisdiction as well as numerous requests to participate in volunteer programs. CMSWS maintains a 24-hour a day, 7 days a week response status for all water quality problems, spills, emergencies, etc. by working in close cooperation with 311 as well as the Charlotte -Mecklenburg Fire and Police Departments, including all the Towns. Emergency spill response services are available through 911. Residents can also request services through the Storm Water Services webpage online and through the use of the mobile CLT Plus app at the following link: https://charlottenc.-o�ges/CLTplus.aspx. 5.4 Outreach Program The outreach strategy for the Mecklenburg County Phase II jurisdictions/entities includes the mechanisms described in this Section, which are estimated to result in over 6,600,000 contacts for the protection and restoration of water quality conditions in the Charlotte -Mecklenburg area during the five (5) year Permit term. Contacts outside the Phase II jurisdictions are included in this calculation, which is unavoidable due to the fact that the program is administered countywide. For each media, event or activity included in the outreach program, the extent of exposure is estimated and recorded. 5.4.1 Utility Bill Inserts 37 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER rl\ Services Utility Bill Inserts (UBIs) with educational stormwater topics are placed inside utility bills (water, sewer, and stormwater) eight (8) times per year and issued to 185,004 customers throughout Mecklenburg County. This outreach mechanism involves the development and placement of an insert into this utility bill that results in the stormwater/water quality message being delivered to over 2,200,000 customers in Charlotte -Mecklenburg during the five (5) year Permit term. These inserts reach the entire target audience described in Section 3.10 with general water quality messages such as how to report suspected pollution problems and measures for reducing stormwater pollution, as well as messages associated with targeted pollutant sources and volunteer opportunities. Figure 4 is the utility bill insert distributed in October 2022. Figure 4: Utility Bill Insert 5.4.2 Brochures and Environmental Notices This outreach mechanism involves the development and distribution of printed brochures, Environmental Notices, and Newsletters to select members of the targeted audience described in Section 3.10, including but not limited to adults, homeowners, pet owners, non-English speaking residents, businesses, and industries. This outreach includes general water quality messages regarding pollution prevention, reporting and regulatory compliance as well as messages associated with specific pollution sources from Table 9 and information regarding water quality volunteer opportunities. Printed brochures are distributed during responses to citizen requests for service, inspections and at event displays. Environmental Notices containing specific information for protection of water quality and compliance with water quality regulations are typically distributed during responses to citizen requests for service and inspections for identifying and eliminating pollution sources. For those jurisdictions that do not utilize social media as described in Section 5.4.5, newsletter articles are sent to residents to inform them of the measures they should take to eliminate pollution sources. The printed brochures and Environmental Notices are anticipated to reach a minimum of 100,000 residents in Charlotte - Mecklenburg during the five (5) year Permit term. 5.4.3 Articles and Newsletters 4D. Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services This outreach mechanism involves the development and publication of articles in local newspapers, newsletters, and online sources available to residents in the Phase II jurisdictions. These sources include but are not limited to the Charlotte Observer, The Recycler, Hola magazine, Axios Charlotte, and Charlotte Five. All of these sources reach the target audience which is described in Section 3.10. The articles seek to educate residents about the impacts of stormwater discharges on water bodies and the steps they can take to reduce pollution, participate in volunteer programs and events, sign up for swim advisories, as well as report suspected pollution problems. The ads are anticipated to reach a minimum of 100,000 residents in Charlotte -Mecklenburg during the five (5) year Permit term. 5.4.4 Media Campaign This outreach mechanism involves the use of radio and television ads to reach the entire targeted audience described in Section 3.10 with messages regarding the measures that can be taken to reduce stormwater pollution as well as messages associated with specific pollutant sources. This outreach mechanism is also used to promote participation in water quality volunteer activities. TV and radio ads run throughout the fiscal year with a very wide circulation. The estimated annual extent of exposure from these ads generally totals greater than 6,000,000. 5.4.5 Social Media This outreach method includes, but is not limited to, Facebook, Twitter, Instagram, and Web Banners to engage citizens in activities for protecting and restoring water quality conditions in Mecklenburg County. Posts include a variety of stormwater-related topics. Figure 5 is a Web Banner that was posted on numerous high -profile websites starting in FY2022 to all CMSWS volunteer programs. The estimated annual extent of exposure from social media generally totals greater than 10,000,000. Figure 5: Web Banner 5.4.6 Targeted Outreach Targeted educational outreach efforts are initiated when responses to service requests, monitoring results or other program activities reveal pollution sources isolated to specific target areas. Educational brochures and/or door hangers are the outreach mechanisms of choice in such W Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services situations; however, a very targeted social media campaign could also be conducted. For example, if elevated fecal coliform levels were detected as a result of water quality monitoring activities and field investigations revealed a large concentration of dogs registered in homes upstream, then a door-to-door educational campaign would be conducted in the area to promote the proper disposal of dog waste, including the distribution of various educational materials. Targeted outreach is also performed on a watershed level based on specific issues such as TMDLs or a specific pollutant of concern. Figure 6 is an example of a targeted education mailer used in the Reedy Creek Watershed. Figure 6: Targeted Education Mailer 5.4.7 Workshops and Video Taped Messages This outreach mechanism involves the use of workshops and/or video taped messages to reach a wide segment of the targeted audience described in Section 3.10. At least two (2) workshops and/or video taped messages will be provided during the five (5) year Permit term reaching an estimated 1,500 persons. To date, several pollution prevention video taped messages have been developed and are available on YouTube. In 2015, CMSWS developed a video entitled "Water Pollution: What to Do?" that describes sources of water pollution, the importance of clean water to the community and the impacts of water pollution as well as how to detect and report illicit discharges. Each of the Phase II jurisdictions/entities is responsible for ensuring that its staff watches this video if, as part of their normal job responsibilities, they may come into contact with or otherwise observe an illicit discharge or illicit connection to the storm sewer. This video is available on the County's MeckEdu website. During the five (5) year Permit term, over 1,000 media contacts are anticipated through the use of videos. 5.4.8 Web Pages This outreach mechanism involves the use of web pages focused on specific water quality topics maintained on the CMSWS website located at http://stormwater.channeck.org. Web pages describe the specific actions necessary to prevent water pollution and instructions for reporting suspected pollution sources. The web pages also target specific business sectors with best .O Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services management practices relating to pollution prevention. In addition, the web pages include a description of all the volunteer programs with instructions on how to register for participation. Web pages are also available that describe water quality monitoring activities in Mecklenburg County and general water quality conditions. This website is promoted through utility bill inserts, print ads, brochures, Environmental Notices, Newsletters, media campaigns, social media post, workshops, and by displays on giveaway materials. The website also appears on all emails generated by staff with CMSWS as well as appears on their business cards. The stormwater website is also available through a link on the websites maintained by Mecklenburg County and the other co-permittees. Annual pageviews for CMSWS's website generally total greater than 300,000. 5.4.9 Educational Presentations and Public Events This outreach mechanism involves the combination of educational presentations, displays, educational materials, handouts, and/or promotional items to reach a very select segment of the targeted audience described in Section 3.10, including adults, dog owners, civic groups, students, landscapers, realtors, and land developers. The messages focus on controlling one or more of the pollutant sources in Table 9 as well as promoting volunteerism. These activities occur throughout the year. Each year CMSWS generally conducts between 30 and 40 educational presentations covering stormwater pollution prevention and reporting and attends 10 to 20 events reaching a total of over 4,000 attendees. In addition, CMSWS has develop age -specific educational information for use in schools and for presentations to school age children. During the five (5) year Permit term, it is estimated that over 200 presentations and events will be conducted/attended by CMSWS reaching over 20,000 residents. 5.4.10 Regional Stormwater Partnership of the Carolinas CMSWS is a member and active participate in the Regional Stormwater Partnership of the Carolinas (RSPC). The RSPC is a non-profit organization whose mission is to work together to educate and bring awareness of stormwater issues and their impact on water quality throughout the Charlotte region. The partnership not only promotes a strong network of stormwater professionals, but it allows multiple municipalities to share various resources, especially in the area of public education and outreach. 5.5 Reaching Mecklenburg County's Diverse Population Mecklenburg County is recognized as having one of the most diverse populations in the State. This diversity is taken into careful consideration when developing and implementing all activities involved in the Public Education and Outreach and Public Involvement and Participation Programs. For example, CMSWS is careful to ensure that all media outlets and educational materials are designed to reach a broad range of languages. In addition, CMSWS partnered with the Regional Stormwater Partnership of the Carolinas and Johnson C. Smith University on a WRRI grant which involved improving public education/outreach and public involvement in three (3) low-income communities in west Charlotte. This is an area identified for needing additional outreach and involvement. Plans are underway to continue to engage the citizens in these communities. In FY2023, an Underserved Communities Reach Plan was 41 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services developed using data from the 2020 Census. This plan conducted a thorough review of all public education and public participation programs in relation to underserved communities and outlined recommendations for improvement. This plan will be updated annually and will guide our education and outreach programs in underserved communities. 5.6 Communication Plan Beginning in FY2021, a Communication Plan was developed and implemented in the Phase II jurisdictions. The purpose of this Plan is to describe the methodology and tools that will be used to promote public education and involvement as well as to communicate information regarding spills and other incidents responded to by CMSWS such as fuel spills, sewage discharges, fish kills and other impacts to surface waters. The Plan establishes four (4) tiers of communication, including Tier I — Major Environmental Incident with Immediate Public Health Concern; Tier II — Environmental Incident with Potential Public Health Concern; Tier III - Environmental Incident with Little to No Public Health Concern; and Tier IV - Stormwater Public Education and Public Involvement Message. The Plan describes each of these tiers and provides examples of incidents/situations where the tier would apply. The Plan provides a description of the step- by-step process to be followed to communicate the necessary information under each of the tiers. The Plan also describes the guidelines and communication tools to be used with the public (external) and with key staff (internal) to ensure clear, factual and transparent communication in all situations. The Plan is maintained in CMSWS's shared folder as follows and is available upon request to the Environmental Manager: G:\Water Quality\WQ—Xfer\WQ\Communication Plan. 5.7 Decision Process The targeted audience for the Public Education Program for the Mecklenburg County Phase II jurisdictions/entities include a wide range of age, ethnic and economic groups. These groups rely on varying mechanisms for receiving information; therefore, a multifaceted educational program was designed to achieve effective communication. The individual BMPs identified in Table 16 reflect this approach as do the measurable goals associated with each BMP. Emails, utility bill inserts, Environmental Notices, brochures, Newsletters, and newspaper ads use the printed word to disseminate information and focus on specific pollutants as well as general water quality issues. This information can be distributed to a broad audience via mailings as well as handed out to individuals when responding to citizen requests for service, conducting inspections, or attending public events. Web pages provide a variety of specific information to a broad audience including the general public, commercial and industrial facilities. Workshops and presentations focus on a relatively small audience but are an effective tool for addressing specific pollution sources and gaining volunteer participation. Television, radio, and social media campaigns broaden the approach to a wide audience and typically convey a more general pollution prevention message. The staff responsible for conducting this public education program for the Mecklenburg County Phase II jurisdictions/entities as identified in Table 11 were selected for their expertise in the development and implementation of a multifaceted public outreach campaign. 42 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 5.8 Program Evaluation The measurable goals for each BMP are described in Table 9. The overall success of the Public Education and Outreach Program is evaluated through the successful achievement of these measurable goals as reported with each NPDES MS4 annual assessment report. At a minimum, the following metrics are included in this annual report: • Number of public events attended. • Number of presentations conducted. • Number and type of social media posts. • Results from public opinion surveys. • Results from using mass media channels of communication, including reach and frequency. Other measures of success for the Public Education and Outreach Program are described below. • Documentation of Stormwater Program Activities — As a baseline measure of success, CMSWS staff will document the completion of Work Plan activities annually that demonstrate achievement of each of the measurable goals for the BMPs associated with this program. All activities will be documented within CMSWS's Cityworks database. • Increasing Awareness — Stormwater Public Opinion Surveys are conducted annually of the general public to measure their awareness of water quality issues as well as their level of concern/interest. The measure of success for the Public Education and Outreach Program is a minimum of 60% of survey respondents indicating they are aware that water flowing into storm drains goes directly to creeks and lakes. On an annual basis, CMSWS staff will evaluate the BMPs for this program and assess progress toward achieving the measurable goals from Table 16 and the measures of success described above. Recommendations for improvement will be made as necessary. During the following fiscal year, program activities and BMPs will be modified as necessary based on the results of this evaluation in order to ensure that the specific goals and objectives of the Public Education and Outreach Program and SWMP are being effectively and efficiently fulfilled. Staff will also evaluate the continued relevance of Table 9 and the effectiveness of the targeted audience. 43 Chaloffe STORM WATER :�� Services SECTION 6: Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 PUBLIC INVOLVEMENT AND PARTICIPATION PROGRAM A Public Involvement and Participation Program has been developed and is currently being implemented for Mecklenburg County's Phase II jurisdictions/entities to comply with the State and local public notice requirements and to engage the community in program development and implementation. The program is administered by CMSWS's Water Quality Program as described in the following Sections. 6.1 Program Goals and Objectives CMSWS establishes its goals and objectives for its Public Involvement and Participation Program, which are evaluated and updated annually as necessary, based on the actions necessary to effectively address the targeted pollutants and pollutant sources identified in Table 9. The current goal of the Public Involvement and Participation Program is to create opportunities for the public to participate in Phase II program development and implementation, as well as to get involved in activities aimed at protecting and restoring water quality conditions. The current objectives of the program are as follows: 1. Make a minimum of one (1) presentation annually to the Charlotte -Mecklenburg Stormwater Advisory Committee (SWAC) to describe the activities performed to comply with Phase II Permit requirements and receive feedback. All SWAC meetings are open to the public. A minimum of one (1) of these presentations during the five (5) year Permit term will be advertised for public comment. 2. Develop and implement volunteer programs to involve the public in activities aimed at protecting and restoring water quality conditions. 6.2 BMP Summary Table Table 17 describes the BMPs implemented as part of the Public Involvement and Participation Program.

Participation in the Program will be promoted through the Public Education and Outreach Program described in Section 5. Volunteer opportunities will be made available to all stakeholder groups, including commercial and industrial facilities, environmental groups, homeowners' associations, civic groups, educational organizations, and interested citizens. 6.4 Mechanisms for Public Involvement and Participation The Mecklenburg County Phase II jurisdictions/entities utilize the Charlotte Mecklenburg Stormwater Advisory Committee (SWAC) to provide and promote a mechanism for public involvement, including receiving input on stormwater issues and the development and implementation of the SWMP. The public is also actively involved in ongoing efforts to restore water quality conditions through volunteer participation in a variety of events, including Adopt - A -Stream, Storm Drain Marking, Volunteer Monitoring, and The Big Spring Clean. The 47 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services following Sections provide additional information concerning these mechanisms for public involvement and participation. 6.4.1 Charlotte Mecklenburg Stormwater Advisory Committee (SWAC) The City of Charlotte, Mecklenburg County and the six (6) Towns established SWAC as its local stormwater management panel in 1994 with the development of their stormwater utility (Charlotte -Mecklenburg Stormwater Services). SWAC reviews stormwater management policies and long-range plans and budgets to make recommendations or offer comments to elected officials. The advisory committee also hears appeals and decides on water quality penalties, service charges, credits, and adjustments. SWAC members are appointed by the Mecklenburg Board of County Commissioners, Charlotte City Council, Charlotte Mayor and Town Boards. SWAC includes representation from all the Phase II jurisdictions in Mecklenburg County. All SWAC meetings are open to the public. Effective January 1, 2003, SWAC began serving as the mechanism for obtaining public involvement in development and implementation of the Phase II Permit in Mecklenburg County. In addition, meetings are held with co-permittees at a minimum of twice a year (oftentimes these meetings are virtual) to provide updates regarding Work Plan implementation and Permit compliance as well as to give co-permittees an opportunity to ask questions. 6.4.2 Public Meetings Public meetings are the mechanism used to comply with the State and local public notice requirements and to engage the community in program development and implementation. Public meetings are held before SWAC each year in the spring to obtain support for the upcoming budget submittal. The meetings include a presentation of the activities performed to fulfill Permit requirements and a request for comments. An advertised public meeting is held before SWAC prior to the submittal of the Permit renewal application every five (5) years. The purpose of this meeting is to provide the public with an opportunity to review and provide comments regarding the Permit application and SWMP. On July 15, 2021, a public meeting was held prior to the submittal of the application for the Permit term ending February 16, 2027. This public meeting was advertised in the Charlotte Observer on June 22 and July 1, 2021. During the meeting, a presentation was given by CMSWS staff describing the measures implemented to control stormwater pollutant sources in the Phase II jurisdictions/entities and the various activities performed to fulfill Phase II Permit requirements as described in the SWMP. Staff informed SWAC that no substantial changes were planned for the new Permit or SWMP. No member of the general public provided comments. A vote by SWAC members at the end of the meeting indicated support of the SWMP and submittal of the Permit application. 6.4.3 Adopt -A -Stream Program Mecklenburg County developed a countywide Adopt -A -Stream Program as part of the Surface Water Improvement and Management (S.W.I.M.) initiative beginning in 1998. This program was significantly expanded with the implementation of the Phase I and Phase II Stormwater Programs by the City of Charlotte and Mecklenburg County, respectfully. The Adopt -A -Stream Program engages volunteers in removing trash and locating pollutant sources in Mecklenburg County streams. Adoption groups include Boy/Girl Scout troops, environmental Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER Services interest groups, homeowners' associations, schools, families, garden clubs, businesses, industries, etc. Training is offered to Adopt -A -Stream groups upon request. The purpose of this training is to familiarize the volunteers with methods for detecting common water quality problems, proper stream walk techniques, and important safety measures. Typically, volunteer groups will adopt a one (1) mile long stream segment. Groups walk their assigned stream segment at least twice a year. The groups are also encouraged to clean their stream segment during The Big Spring Clean event. The groups keep records of their Adopt -A -Stream activities. These records are submitted to CMSWS following the completion of stream cleanup activities. All records are input by staff into the Volunteer Database, which is maintained as part of EDMS. CMSWS follows up on identified pollution problems to ensure that they are eliminated, and water quality is restored as well as coordinates the proper disposal of all trash and debris removed from streams by adoption groups. 6.4.4 Storm Drain Marking Program Mecklenburg County developed a countywide Storm Drain Marking Program as part of the S.W.I.M. initiative beginning in 1998. This program was significantly expanded with the implementation of the Phase I and Phase II Stormwater Programs by the City of Charlotte and Mecklenburg County, respectfully. The Storm Drain Marking Program uses volunteers to place CharloNa-UwWonburg J '.4 STORM To Report Pollution .WATER CALL 311 �� Services N decals on storm drains with the message "Do Not Dump — Drains to Creek" (see Figure 7). Volunteer groups include Boy/Girl Scout troops, environmental interest groups, homeowners' associations, schools, garden clubs, families, businesses, industries, etc. NO ECHE BASURA — DESCARGA AL ARROYO Typically, volunteer groups will select _ several streets within a neighborhood for � marking. CMSWS provides the groups Figure 7: Storm Drain Marker with decals, adhesive, safety vests, gloves, and information forms. Following the completion of storm drain marking activities, the groups submit a completed information form to CMSWS that includes the street names and number of drains that were marked as well as information concerning the condition of storm drains and whether any pollutants were detected. All information is input by staff into the Volunteer Database, which is maintained as part of EDMS. CMSWS follows up to ensure the elimination of illegal dumping activities and maintains records of storm drains that have been marked. 6.4.5 Surface Water Clean Up From 1993 through 2014, CMSWS held an annual surface water cleanup day working in cooperation with N.C. Big Sweep. In March 2015, N. C. Big Sweep was dissolved as a non- profit organization. CMSWS now sponsors an annual clean up event called The Big Spring Clean. The purpose of the event is to use volunteers to remove trash and debris from streams and lakes. During the event, Adopt -A -Stream groups are encouraged to clean up their assigned stream segments and additional volunteers are used to expand the effort to include un-adopted EZ Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services stream segments. The event has typically been held on the Saturday following the end of Creek Week. The event is advertised, and volunteers are solicited through the various media outlets previously listed. Records are kept concerning the number of volunteers and tons of trash and recycling removed. The event is coordinated county -wide by CMSWS. 6.4.6 Volunteer Monitoring CMSWS maintains a volunteer monitoring program to assess general water quality conditions in streams located in the Phase II jurisdictions. There are three (3) types of volunteer monitoring programs available. The traditional program includes the use of chemical test kits which can be checked out and used to collect data on stream quality that is submitted to CMSWS for review and follow up. The second program which is called Streamside Visual Assessment involves visually assessing streams and completing a field data sheet to document current conditions. The third program is called Streamside Snapshot which encourages volunteers to submit photos of the stream at select sites which are identified with signs. This program has also been expanded to lake coves where volunteers can submit pictures of a cove to report potential algae blooms. Data is used to identify potential water quality problems that are referred to staff for follow up action. 6.4.7 Volunteer Appreciation Campaign An annual appreciation campaign is held to acknowledge the achievements of volunteers toward restoring the quality and usability of Mecklenburg County's surface water resources. The campaign includes a variety of methods to recognize volunteers. For example, volunteer groups of the year are selected and recognized via social media and provided prizes. Special events for volunteers may also be held as part of the campaign. 6.5 Decision Process Mecklenburg County's Public Involvement and Participation Program focuses on the use of multiple mechanisms for getting the public involved in efforts to restore the quality of Mecklenburg County's surface water resources as well as to comply with the State and local public notice requirements and to engage the community in program development and implementation. The rationale for the development of such a program is that multiple approaches are needed in order to involve all age, ethnic and economic groups in Mecklenburg County. Some individuals will prefer more passive involvement through participation in public meetings whereas others may elect to become more actively involved through participation in the Adopt -A -Stream, Storm Drain Marking and Volunteer Monitoring Programs. The Adopt -A - Stream Program is more physically challenging and is popular among the age group ranging from 15 to 50 years of age. The Storm Drain Marking Program appeals to volunteers who are not interested in walking streams but who are willing to place markers on storm drains in their neighborhoods. This is particularly popular among volunteers greater than 50 years of age. Volunteer Monitoring is typically performed by schools whereas tree planting events and The Big Spring Clean appeal to all age groups and is a popular volunteer event for families and large groups. The individual BMPs identified in Table 17 reflect this approach as do the measurable goals associated with each BMP. 50 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan —NPDES # NCS000395 —November 2022 WATER services 6.6 Program Evaluation The measurable goals for each BMP are described in Table 17. The overall success of the Public Involvement and Participation Program is evaluated through the successful achievement of these measurable goals as reported with each NPDES MS4 annual assessment report. At a minimum, the following metrics are included in this annual report: • Public meetings held and number attending. • Volunteer programs conducted and number participating. Volunteer recognition activities conducted and number attending. Other measures of success for the Public Involvement and Participation Program are described below. • Documentation of Stormwater Program Activities — As a baseline measure of success, staff will document completion of Work Plan activities that demonstrate successful fulfillment of the BMPs associated with this program. All activities will be documented within CMSWS's Cityworks database and Environmental Data Management System (EDMS). • Increasing Number of Volunteers — CMSWS estimates and records participation in all its volunteer programs. This information will be compiled and tracked as a measure of program effectiveness. Data is maintained in a Volunteer Database, which is a component of as well as Excel spreadsheets. Data is included in each annual report for this Phase II Permit. The indicator of success is an increase in the number of volunteers compared to the average of the three (3) previous fiscal years, including (but not limited to) Adopt -A -Stream, Storm Drain Marking, Tree Maintenance, Streamside Chemical, Streamside Snapshot, Creek ReLeaf, Volunteer Monitoring, Big Spring Clean, 2nd Saturday, Volun. Thursday, and Scoop the Poop. On an annual basis, CMSWS staff will evaluate the BMPs assigned to this program and assess progress toward achieving the measurable goals from Table 17 and the measures of success described above. Recommendations for improvement will be made as necessary. During the following fiscal year, program activities and BMPs will be modified as necessary based on the results of this evaluation in order to ensure that the specific goals and objectives of the Public Involvement and Participation Program and SWMP are being effectively and efficiently fulfilled. 51 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan —NPDES # NCS000395 —November 2022 WATER services SECTION 7: ILLICIT DISCHARGE DETECTION AND ELIMINATION PROGRAM An Illicit Discharge Detection and Elimination (IDDE) Program has been developed and is currently being implemented in Mecklenburg County's Phase II jurisdictions/entities for the purpose of detecting and eliminating illicit discharges into the MS4. The program is administered by CMSWS's Water Quality Program as described in the following Sections. 7.1 Program Goals and Objectives CMSWS's establishes its goals and objectives for its IDDE Program, which are evaluated and updated annually as necessary, based on the actions necessary to effectively address the targeted pollutants and pollutant sources identified in Table 9. The current goal of the IDDE Program is to detect and eliminate illicit discharges into the MS4, which are defined in 40 CFR 122.26(b)(2)) as discharges that are not composed entirely of stormwater except discharges pursuant to a NPDES Permit (other than the NPDES Permit for discharges from the municipal separate storm sewer) and discharges resulting from firefighting activities as well as incidental non-stormwater discharges or flows that are not significant contributors of pollutants as described in Section 7.7 of this document. The details regarding this program are described in CMSWS's "Illicit Discharge Detection and Elimination Manual" available at the following website: http:Hstormwater.charmeck.org (select "Regulations", select "Mecklenburg County", select "Manuals & Guidelines", select "Illicit Discharge Detection & Elimination Policies and Procedures"). The objectives of the program are as follows: I. Develop, implement and enforce a program to detect and eliminate illicit discharges into the MS4, including appropriate policies, procedures, form letters and enforcement guidance. 2. Maintain a storm sewer system map, showing the location of all major outfalls and the names and location of all waters of the United States that receive discharges from those outfalls. 3. Prohibit, through ordinances, or other regulatory mechanisms, non-stormwater discharges except incidental non-stormwater discharges or flows that are not significant contributors of pollutants as described in Section 7.7 and implement appropriate enforcement procedures and actions. 4. Implement a plan to detect and address non-stormwater discharges, including illegal dumping, to the MS4. 5. Inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste. 6. Address the following categories of non-stormwater discharges or flows (i.e., illicit discharges) only if identified as significant contributors of pollutants to the MS4: water line flushing, landscape irrigation, diverted stream flows, rising ground waters, uncontaminated ground water infiltration, uncontaminated pumped ground water, discharges from potable water sources, foundation drains, air conditioning condensation, irrigation water, springs, water from crawl space pumps, footing drains, lawn watering, individual residential car washing, flows from riparian habitats and wetlands, dechlorinated swimming pool discharges, and street wash water (discharges or flows from firefighting activities are excluded from the effective prohibition against non- stormwater and need only be addressed where they are identified as significant sources of pollutants to waters of the United States). 52 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 7.2 BMP Summary Table Table 18 describes the BMPs implemented as part of the IDDE Program.

All written procedures and forms for the execution of the IDDE Program are contained in this document, including links to Standard Operating Procedures (SOPS) that include detailed implementation procedures. The Manual is reviewed and updated every five (5) years whereas the more detailed SOPS are reviewed and updated annually. The IDDE Manual includes information regarding the following: • Legal authority, including right of entry. • Coordination with other agencies. • Identification of priority areas likely to have illicit discharges. • Methods used to identify illicit discharges and connections. • Written procedures for conducting investigations of identified illicit discharges and connections. • Written procedures for conducting dry weather flow field observations. • Tracking illicit discharges and connections to a source. • Eliminating sources of illicit discharges and connections. • Sanitary sewer failures. • Documentation. • Employee training. • Provisions for program assessment and evaluation. 7.4 Storm Sewer System Mapping On August 31, 2006, CMSWS completed the storm sewer maps for all the Phase II jurisdictions in Mecklenburg County. These maps show the locations of inlets, outlets and receiving waters as well as identify the corresponding six -square mile drainage areas. As part of this mapping program, CMSWS also identified dry weather flows to the storm sewer system and initiated the measures necessary to eliminate pollution sources. The source of information for the development of these storm sewer maps was 2002 digital aerial photography (1 foot per pixel resolution .tif images, compressed 50:1 into .sid format) provided by Mecklenburg County Mapping/GIS Services. The aerial photography was loaded into Hewlett-Packard iPAQ handheld computers that were equipped with both ESRI Arc Pad 6.0.3 GIS software and Trimble GPS Correct. This mapping software package was configured to store important information relevant to the storm sewer system and the water quality conditions observed. A Trimble Pathfinder Pocket GPS unit was connected to the handheld computer in order to geo-reference all data collected. CMSWS staff conducted field inspections to locate all storm sewer system inlets, 57 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER �—� S.MceS outlets and receiving streams using the aerial photos loaded into the handheld computer as a reference. Once located, a geo-referenced position for the inlets and outlets was determined using the Trimble GPS unit. Other field data was also collected during the inspections including the general condition of the storm drain, the name of the receiving stream and whether dry weather flow or other potential pollution problems were observed. If such problems were detected, the following additional information was collected: • Estimated flow rate. • Odors. • Coloration. All observed dry weather flows were sampled for fecal coliform bacteria, surfactants, fluoride, and oil and grease. Follow up field investigations were performed to identify and eliminate all pollution sources. All follow up activities were documented in a report maintained in CMSWS's computer database. Following the field inspections, the digital data was downloaded by CMSWS staff and stored in an ESRI shapefile format (with attributes). CMSWS staff post - processed the data to include the corresponding six -mile sub -basin identification number as an added attribute. After the inventory was completed, storm sewer system maps were created for use in the implementation of the IDDE Program. Staff with CMSWS conduct field investigations to identify dry weather flows to the storm sewer system during responses to citizen requests for service and while conducting stream walks and various inspection activities. The necessary follow up actions are performed to identify and eliminate pollution sources as described in Section 7.7. All data is maintained in a GIS database and is available for use by staff in the identification and elimination of illicit discharges through the Cityworks database (see Figure 8). ► Retrofits va u"`! a ° V` ;'Amb Ad ► Facility Inspections ' 7 i ► Mitigation Projects ► Phase I Outtalls ► Phase II Outfalls —Phase II Storm Water Inventory Inlet s< / Outtall n • t I _ jai ? • MajorOutfall <. ►Tree Planting Sites r ►BMP +r ►BMP Project ► Six Mile Basin ►Town Boundaries .......... - '' Y 7� i ► Watershed Boundaries xi 4_ �� r 1 ► Charlotte Water r ► City Stormwater 1 v! r Annotation e r 1 / y ► TOD0100V Basemao Figure 8: Screen Shot from Cityworks of Storm Drain Inlets, Outlets, and Receiving Streams The storm sewer system map is updated daily by Mecklenburg County's GIS Department in order to capture inlets and outlets added by new development. This is completed as part of their ongoing process to update the impervious area coverage that is included in the stormwater billing process. GIS staff use "Nearmap Aerial Imagery" to locate the new inlets and outlets. These Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services high -resolution, aerial maps are widely used by both the public and private sector to rapidly identify features on the ground with a very high degree of accuracy. Mecklenburg County collects aerial imagery twice a year during "leaf off' conditions, which is typically in February and October. EagleView Pictometry is used to enhance images that are difficult to identify due to shadows and other distortions. This patented high -resolution aerial image capture process uses low -flying airplanes to photograph locations on the ground, depicting up to 12 oblique perspectives (shot from a 40-degree angle) as well as an orthogonal (overhead) view to produce a 360-degree view making objects easier to recognize and interpret. Once the inlets and outlets are identified, a new point is created in ESRI's ArcGIS, including an object ID number, date collected, feature type (inlet or outlet), and collection method. GIS provides CMSWS with a list of the newly collected storm sewer system features twice a year based on their analysis of new aerial imagery. Outfall features are validated by CMSWS's staff during the fall Stream Walk activities. Staff collect additional attribute information using the ArcGIS Collector application, including the outfall type (major or minor, FES, endwall, exposed pipe, etc.), outfall shape, outfall material, endwall material, and the diameter of the outfall. Staff also record the condition of the outfall, dry weather flows, and any other potential illicit discharges. Follow up actions are completed as necessary to ensure the elimination of identified pollution sources. SOPS have been developed for the storm sewer system mapping process, including follow up for potential pollution sources, and are available upon request. 7.5 Pollution Control Ordinance In April 2004, the Town of Davidson adopted a "Surface Water Pollution Control Ordinance" that prohibits illicit discharges, illicit connections and improper disposal to surface waters and storm sewers within their corporate limits as authorized by North Carolina General Statute (NCGS) 160A-174. On May 5, 2004, Mecklenburg County adopted the same ordinance for the unincorporated areas of the county as authorized by NCGS 153A-121. A separate ordinance was adopted for the Town of Davidson because they have jurisdiction in Iredell County where the County Attorney indicated that Mecklenburg County's ordinance would not be applicable. On June 8, 2004, the Town of Pineville adopted a resolution allowing Mecklenburg County to enforce its ordinance within their corporate limits as authorized by NCGS 153A-122. On June 21, 2004, the Towns of Cornelius and Huntersville adopted the same resolution followed by the Town of Mint Hill on June 24, 2004. The Town of Matthews had adopted a separate Stormwater Pollution Control Ordinance on November 27, 2000. CMSWS has been delegated the authority to enforce these ordinances in cooperation with the respective jurisdictions. This regulatory mechanism was chosen for prohibiting illicit discharges to storm sewers and surface waters in the Phase II area due to the success of a similar ordinance in effect in the Phase I area in the City of Charlotte since November 25, 1995. These ordinances prohibit illicit discharges, illicit connections and improper disposal to the storm drain system except for the incidental non- stormwater flows that do not significantly impact water quality described in Section 3.8. CMSWS reviews the above -described surface water pollution control ordinances each fiscal year and modifies them as necessary to ensure that adequate legal authority is maintained to prohibit illicit connections and discharges, and to properly enforce the provisions of the IDDE Program. Changes were made to the Town of Matthews' and Mecklenburg County's ordinances effective February 12, 2018 and May 21, 2020, respectively. Enforcement procedures and Notice of 59 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Violation shells, etc. were changed to correspond to the new ordinance requirements. A list of the major changes is provided below. 1. All Sections: Various wording changes were made throughout the document without changing the regulatory requirements or overall intent of the ordinance. 2. Definitions: Definitions were added and changed as necessary in Section 4 to support ordinance revisions. 3. Prohibitions, Accidental Discharge(s): Accidental discharges were added as a violation of the ordinance. 4. Prohibitions, Use of High PAH Pavement Products Prohibited: The use of pavement products with greater than 0.1 % polycyclic aromatic hydrocarbons (PAH) by weight on an asphalt or concrete surface was added as a violation of the ordinance. 5. Prohibitions, Obstruction: Obstructing, hampering, or interfering with county personnel carrying out official duties authorized by this ordinance was added as a violation. 6. Prohibitions, Allowable Incidental Discharges of Non -Storm Water: The following allowable discharges were added: diverted stream flows; and flows from riparian habitats and wetlands. Swimming pool and hot tub discharges continue to be allowed provided they do not contain chlorine, bromine, salt, or any other treatment chemicals. Backwash discharges from swimming pools and hot tubs and saltwater pool discharges are identified as prohibited in the revisions. Single-family and charity vehicle washing continues to be allowed; however, designated vehicle wash areas at multi -family residential complexes are identified as prohibited in the revisions if they connect, directly or indirectly, to the stormwater system or the waters of the state. In addition, the revisions specify that charity vehicle washing performed by the same organization or at the same location on a routine basis (more than one time in a thirty -day period) is not allowed. 7. Powers and Authority for Inspection, Search Warrants: The revisions added a provision for obtaining a search warrant to conduct inspections to the extent permitted by law. 8. Enforcement and Penalties, Remedies Not Limited: The revisions add a provision that the remedies provided in the ordinance are not exclusive and may be combined with any other remedies authorized by law. 9. Enforcement and Penalties, Notice of Violation: The revisions add a provision that any person who violates the ordinance, or allows a direct or indirect, act or acts which causes a violation of the ordinance will be issued a written notice of violation. The specific content of the notice is also described as well as how it will be served. 10. Enforcement and Penalties, Civil Penalties(c): The revisions clarify that a civil penalty may be assessed for the time period from the date the violation first occurs until the date that the violation ceases as verified by staff. The revisions also indicate that penalties may be assessed concurrent with a notice of violation when staff are hampered or obstructed from carrying out official duties; a repeat or continuing violation has occurred; and/or there is a willful or intentional violation of the ordinance. In addition, the revisions add the following factors for inclusion in determining the amount of a civil penalty: knowledge of the requirements by the violator and/or reasonable opportunity or obligation to obtain such knowledge; and technical and economic reasonableness of reducing or eliminating the violation. 11. Enforcement and Penalties, Compliance Agreement(gh The revisions add a provision for the use of a Compliance Agreement as a remedy to obtain compliance. 12. Enforcement and Penalties, Compliance Order(f): The revisions add a provision for the 11 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services use of a Compliance Order to obtain compliance. 13. Enforcement and Penalties, Cease and Desist Order(): The revisions add a provision for the use of a Cease and Desist Order to obtain compliance. 14. Enforcement and Penalties, Withholdingof f Inspections, Permits, or Other Approvals(h): The revisions add a provision for withholding inspections, permits, and other approvals as a means for obtaining compliance. 15. Enforcement and Penalties, Abatement by the County: The revisions include specific information regarding the process for abatement of violations by the County when the violator fails to comply. 16. Enforcement and Penalties, Emergencies: The revisions include provisions for immediate cessation and abatement of violations when there is an immediate threat to public health, safety or the environment. 17. Enforcement Remedies and Penalties, Injunctive Relief. The revisions include a provision for obtaining injunctive relief through the courts as an added compliance measure. On August 25, 2020, changes were made to the Town of Davidson's ordinance to ban the use of pavement products with greater than 0.1 % polycyclic aromatic hydrocarbons (PAH) by weight, which is the same as the ban in Mecklenburg County's and Matthews' ordinances described in #4 above. On January 26, 2021, the other 16 changes listed above were made to Davidson's ordinances. Enforcement procedures and Notice of Violation shells, etc. were changed to correspond to the new ordinance requirements. During the week of April 26, 2021, the State audited Mecklenburg County's Phase II Permit. During this audit, it was determined that the Town of Mint Hill had annexed area in Union County since the original adoption of Mecklenburg County's Surface Water Pollution Control Ordinance and Mint Hill's resolution in 2004, which raised the question as to whether a separate ordinance was necessary for Mint Hill as was done for Davidson in 2004. The County Attorney in 2004 who decided that a separate ordinance was necessary for Davidson has since retired. The new County Attorney, Tyrone Wade, was consulted. In an email dated April 29, 2021, Mr. Wade concluded that the resolution adopted by Mint Hill in 2004 granted authority to Mecklenburg County to enforce its ordinance "within the Town corporate limits" with no differentiation as to which County these corporate limits are located. Therefore, Mr. Wade concluded that a separate ordinance was not necessary because Mecklenburg County's ordinance was enforceable in the corporate limits of Mint Hill in Union County by way of the Town's resolution. The same determination was made by Kevin Bringewatt, Mint Hill's attorney. This information was provided to the State auditor who was accepting of the determination. Copies of the above ordinances are available on the following website: hitp:Hstonnwater.charmeck.org (select "Regulations", select jurisdiction, select "Stormwater Pollution Control"). 7.6 Enforcement Enforcement guidance and procedures were developed and became effective at the same time as the ordinances described in Section 7.5. These procedures include guidelines on when a notice 61 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services of violation is to be issued and the proper sections of the ordinance to cite. The procedures also provide guidance on the assessment of penalties. All appeals to the ordinances are heard by SWAC except in the Town of Matthews where appeals are heard by their Environmental Committee. Further information regarding the implementation of the ordinances and enforcement actions is contained in CMSWS's IDDE Manual available at the following website: hgp:Hstormwater.charmeck.org (select "Regulations", select "Mecklenburg County", select "Manuals & Guidelines", select "Illicit Discharge Detection & Elimination Policies and Procedures"). 7.7 Detection and Elimination CMSWS's IDDE Manual describes the actions taken to identify and eliminate illicit discharges, which includes the following four (4) primary steps: 1. Identify priority areas likely to have illicit discharges. 2. Confirm the presence of an illicit discharge. 3. Track the discharge to its source. 4. Eliminate the source. The following subsections briefly describe these four (4) components of the IDDE Program. More detailed information is provided in CMSWS's IDDE Manual. 7.7.1 Identifying Priority Areas Priority areas with a higher likelihood of illicit discharges are typically identified through: 1. Citizen requests for service regarding potential water quality problems. 2. Total number and location of Notice of Violations issued. 3. Routine water quality monitoring activities. 4. Volunteer activities. 5. GIS mapping. 7.7.1.1 Citizen Requests for Service CMSWS has an ongoing public education campaign focusing on illicit discharges and connections for the purpose of increasing public awareness and reports from citizens of suspected problems. This campaign informs residents how to identify illicit discharges and connections, how they negatively impact their quality of life and what they can do to eliminate them, including proper reporting to the 311 stormwater helpline. A broad range of media outlets have been utilized in this campaign, including television, radio and print. Efforts have been highly successful as indicated by the increase in the number of reports received from citizens regarding suspected illicit discharges. CMSWS considers its responses to these citizen reports or service requests to be of the utmost importance not only from a customer service standpoint, but also because this is how most illicit discharges and connections are identified. All staff members receive annual training regarding responses to service requests and proper customer service. All service requests are forwarded to Supervisors immediately following receipt. To ensure an effective and efficient response, Supervisors place all service requests into one of the following three (3) categories based on the type of response required: 62 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Category 1: Health / Safety Threat Category 2: Spill / Illegal Discharge / Water Quality Violation Category 3: Request for Assistance / Information (non -emergency) Category 1 service requests are considered a threat to the health and safety of the public and are given the highest priority. They are always responded to as soon as possible upon receipt and often include involvement by a Supervisor working closely with field staff. Examples of Category 1 service requests are as follows: 1. Sewage or other pollutant discharge to a known swimming area. 2. Sewage or other pollutant discharge to a playground or other areas where people could easily come in contact with pollutants. 3. Discharge of pollutant near a drinking water intake. Category 2 service requests include spills, illegal discharges and water quality violations and are also considered to be a high priority. They are responded to within two (2) hours of receipt since they may easily progress to a Category 1. Examples of Category 2 service requests are as follows: 1. Any active discharge of pollutants such as sewage and fuel spills. 2. Numerous dead fish in creek. 3. Someone currently in the act of violating a water quality regulation. 4. Request from Fire or Police to respond. Category 3 service requests include requests for assistance and information that are non - emergency in nature and do not require immediate attention. These service requests are responded to as soon as possible, but never any later than two (2) workdays from the receipt of the request. Examples of Category 3 service requests are as follows: 1. Disturbance has occurred in a stream buffer. 2. Request for water quality data. 3. Someone has routinely dumped oil on ground. 4. XYZ Company may be disposing of waste illegally. For all responses to citizen requests for service, staff ensure that all pollution sources are eliminated, negatively impacted areas are restored, and the necessary actions taken to prevent recurrence, including the distribution of educational information. If violations of water quality ordinances are observed, a notice of violation will be issued (approximately within two business days) and a compliance deadline will also be established. Staff follow up to ensure compliance by this deadline. In many cases, the violator is required to submit written notification of the actions undertaken to achieve compliance and prevent recurrence. Responses to citizen requests for service are overseen by Supervisors and documented in Cityworks. All documentation is reviewed and approved by Supervisors prior to closing. More information regarding responses to citizen requests for service is provided in the Illicit Discharge Detection and Elimination (IDDE) Manual located at the following website: hgp:Hstormwater.charmeck.org (select "Regulations", select "Mecklenburg County", select "Manuals & Guidelines", select "Illicit Discharge Detection & Elimination Policies and Procedures"). e Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 7.7.1.2 Routine Water Quality Monitoring Activities The monitoring activities performed by CMSWS for identifying priority areas for illicit discharges include fixed interval monitoring and the use of a Continuous Monitoring and Alert Notification Network (CMANN). Samples for fixed interval monitoring are collected by hand (grab samples) on the second Tuesday of each month at 10 designated stream monitoring sites as shown in Figure 9. At each stream monitoring site, samples are collected and analyzed for 17 water quality parameters as follows: ammonia -nitrogen, fecal coliform bacteria, total kjeldahl nitrogen, nitrate/nitrite, total suspended solids, total phosphorus, enterococcus, e. coli, turbidity, suspended sediment, magnesium, calcium, hardness, and copper (dissolved). Lead (dissolved), chromium (total), and zinc (dissolved) are collected in the first month of each quarter. The primary purpose of the fixed interval monitoring program is to assess the general water quality conditions of the streams and to identify potential pollution problems at the watershed scale. CMANN data is collected on a fixed time interval (usually every hour) using automated equipment set-up at seven (7) designated stream monitoring sites as shown in Figure 9, excluding MY14, MC36, MC2, MC2A1, MC3E, and MC40C. CMANN is used to measure turbidity, pH, temperature, conductivity, and dissolved oxygen. All data is stored in a data logger and transmitted via a wireless modem for display on the CMANN website at https:Hcmann.mecknc.gov/. The primary purpose of the CMANN monitoring program is to assess water quality conditions for overall watershed health and identify pollution problems. All data from the above monitoring activities is delivered electronically to a Quality Assurance and Quality Control (QA/QC) Officer (position title is Environmental Analyst) with CMSWS, who is responsible for the compilation, review, verification, validation, and warehousing of all water quality monitoring data products. Immediately upon receipt of this data, the QA/QC Officer identifies all exceedances of local Watch/Action Levels and State water quality standards. Within one workday from receipt of the data, the QA/QC Officer reports all observed exceedances to Supervisors who establish the area upstream of the sample location as a priority for the identification of illicit discharges. The Supervisor assigns all priority areas to staff for the initiation of immediate follow up actions for the purpose of identifying and eliminating pollution sources and restoring water quality conditions. :A ' Charlotte Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER Services Figure 9: Phase II Stream Monitoring Sites In addition to exceedances of local Watch/Action Levels and State water quality standards, CMSWS uses an index of water quality conditions referred to as the Stream Use Support Index or SUSI to identify areas with negatively impacted water quality conditions and a high likelihood of illicit discharges (see Figure 10). These are areas where water quality conditions are on the decline but may not be degraded enough to trigger a follow up for an Action or Watch Level exceedance as described above. SUSI includes five (5) broad categories of parameters that were determined to be the most important indicators of pollution in Charlotte -Mecklenburg. These five (5) categories, which are called sub -indices, are as follows: 1. Bacteria (Fecal Coliform Bacteria) 2. Metals (Copper, Zinc, Lead and Chromium) 3. Biological (Macroinvertebrate and Habitat) 65 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER ��, Services 4.

V ATE�in Figure 10: Stream Use Support Index (SUSI) Map (April through June 2022) SUSI also incorporates data collected over three (3) time horizons, including short term (data from the current month), middle term (data from the past 10 to 12 months) and long term (data from the past 1 to 2 years). SUSI rates water quality conditions across Mecklenburg County using data collected over these time horizons and displays these conditions in a color -coded map as either Supporting, Partially Supporting, Impaired or Degraded as shown in Figure 10. The QA/QC Officer previously described generates SUSI maps quarterly and provides them to the Supervisors who consider areas identified with Impaired and Degraded conditions as priority areas for illicit discharges or other pollution problems. The Supervisors consider other data and information available to them in assigning these priority areas to staff for the initiation of follow up actions for the purpose of identifying and eliminating pollution sources and restoring water quality conditions. :. Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Additional detail regarding water quality monitoring activities is available on CMSWS's website: http://stormwater.charmeck.or2 (select "Surface Water Quality", select "Monitoring"). 7.7.1.3 Volunteer Activities CMSWS has three (3) volunteer programs that contribute toward the identification of priority areas with a higher likelihood of illicit discharges, including Adopt -A -Stream, Storm Drain Marking and Volunteer Monitoring. The objective of these programs is to engage the citizens of Charlotte -Mecklenburg in activities for protecting and restoring surface water resources, including the identification illicit discharges. Typically, volunteers will report to the volunteer coordinator the potential presence of an illicit discharge. This report is forwarded to a Supervisor who will schedule staff activities to confirm the presence of an illicit discharge as described in Section 7.7.2. 7.7.1.4 GIS Mapping CMSWS utilizes GIS mapping capabilities to identify priority areas for illicit discharges. CMSWS maintains all its water quality data and information, including Work Plan assignments, activity/inspection reports, asset information, etc., in its Environmental Data Management System (EDMS). EDMS contains multiple databases, including Cityworks that is used for GIS mapping, citizen requests for service, and activity and inspection reports. Cityworks is a work management tool built around the use of ESRI's GIS environment, which tracks activities based on identified features referred to as assets. CMSWS has incorporated numerous GIS asset layers into Cityworks that are useful in prioritizing areas for illicit discharges. Figure 11 provides a screen shot from Cityworks with the GIS asset layers activated for the Phase II storm water inventory. The green dot in the center indicates the location of a suspected water quality problem reported through the receipt of a citizen request for service that has been geocoded into Cityworks. Staff can access GIS asset layers using the "Legend" tab in Cityworks, which is used for prioritizing specific locations for illicit discharges. This is one of the many techniques available to staff for identifying pollution sources using GIS. e Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER �—� S.MceS 4 " ► Retrofits �r • ► Facility Inspections / ►Mitigation Projects ► Phase I Outfalls • ► Phase 11 Outfalls ~ -Phase 11 Storm Water Inventory 8 • 8 I Inlet S , .

For the field screening activities described above, staff ensure pollution sources are eliminated, negatively affected areas are restored, and necessary actions are taken to prevent recurrence. This can be accomplished through the distribution of educational information and/or enforcement. If violations of water quality ordinances are observed, notices of violation are issued within two (2) workdays of detection and a compliance deadline is established. Staff follow up to ensure compliance by this deadline. In many cases, the violator is required to submit written notification of the actions undertaken to achieve compliance and prevent recurrence. All activities are overseen by Supervisors and documented in Cityworks. All documentation is reviewed and approved by the Supervisor prior to closing. 7.7.2.1 Illicit Discharge Elimination Program (IDEP) IDEP involves investigating select locations in identified priority areas to confirm illicit discharges using visual observations. An example is as follows: :: Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services A Supervisor identifies a priority area for an illicit discharge from the receipt of a citizen request for service and assigns to staff for follow up action. Staff s investigation does not reveal a pollution problem during the inspection. However, based on information provided by the citizen, staff determines there is a high probability for an intermittent discharge which may warrant additional investigation of the area. One option available to the Supervisor for confirming the discharge is to establish an IDEP run in the area. This is accomplished by assigning staff to perform visual observations at specific intervals in the area, such as bridge crossings, on a short term, frequent schedule to confirm the presence of a discharge. This is particularly effective for discharges that are detectable using human senses such as a sewer overflow and surfactants from vehicle washing. Once the discharge is confirmed and the source identified, the IDEP activities are discontinued. Industrial inspections are performed in the Phase II jurisdictions by CMSWS through IDEP. Every fiscal year CMSWS selects a minimum of six (6) industrial facilities for inspection based on their potential to pollute. Most inspections are performed at the industrial facilities included in Table 7. Inspections are conducted and reports generate in accordance with established SON that are available upon request to the Environmental Manager with the Water Quality Program. Follow up actions are implemented as necessary to identify and eliminate pollution sources identified through these inspections. Facility inspections are performed in the Phase II jurisdictions by CMSWS through IDEP. A common target for these inspections is the multi -family residential complex with a private sewer collection system that has a history of poor maintenance and sewer spills. CMSWS will conduct inspections of these systems through IDEP to identify and eliminate sewer discharges and ensure proper system maintenance. The complex is thoroughly inspected for active sewer discharges and signs of previous overflow problems such as limed areas, toilet paper, etc. Corrective actions are implemented as necessary to ensure that all problems are corrected, and the system is properly maintained to prevent recurrence. 7.7.2.2 Short Term Monitoring Short term monitoring involves monitoring select parameters at specific stream locations and/or stormwater outfalls in identified priority areas to confirm illicit discharges. An example is as follows: A Supervisor identifies a section of stream as a priority area for illicit discharges as a result of an Action Level exceedance from a fixed interval monitoring run. One option available to the Supervisor is to establish Short Term Monitoring along the stream section to confirm the presence of a discharge. This is accomplished by identifying sample collection locations along the stream and assigning staff to monitor these locations for select parameter(s) using field and/or laboratory analyses on a short term, frequent schedule. This is particularly effective for discharges that are typically not detectable using human senses such as discharges of organics or metals. Once the discharge is confirmed and the source identified and eliminated, the monitoring activities are discontinued. 7.7.2.3 Hot Spot Investigations Hot spot investigations are performed at a select stream location, stormwater outfall, sewer :' Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services manhole, lift station, etc. with a history of problems in priority areas to confirm illicit discharges using visual observations. Hot spot investigations are similar to IDEP runs except they involve investigations of a single location as opposed to IDEP which usually incorporates multiple locations. 7.7.2.4 Stream Walks This activity involves walking an entire stream reach in identified priority areas to confirm illicit discharges using visual observations and monitoring activities. Streams walks differ from IDEP and hot spot investigations because the entire stream reach is inspected as opposed to select locations along the reach. In addition, hot spot and IDEP investigations can involve locations other than streams such as a parking lot or a business corridor. CMSWS is on a schedule to walk all perennial streams in the Phase II jurisdictions within a rotating five (5) year time frame. Hot spot stream segments are walked on a more frequent basis. 7.7.2.5 Dry Weather Flow Investigations Dry weather flow investigations involve inspecting stormwater outfalls after a minimum of 72 hours of no measurable rainfall and identifying dry weather flows. The sources of such flows are typically either groundwater infiltration into the storm drainpipe, lawn watering, air conditioning condensate or an illicit discharge. CMSWS utilizes various data and information to identify areas where there is a high potential for illicit discharges. Staff are assigned to perform outfall inspections in these areas. During these inspections, data is collected and recorded in a GIS application in accordance with established procedures. Immediately following the identification of dry weather flows, efforts are undertaken by CMSWS to confirm an illicit discharge. Staff will physically observe the discharge for pollutant indicators such as discoloration, odor, solids, etc. and perform water quality monitoring for select parameters, including temperature, dissolved oxygen, conductivity, pH, fecal coliform bacteria, total phosphorus, and flow. Follow up actions are implemented as necessary to ensure that all pollution sources are eliminated, and recurrence prevented. 7.7.3 Tracking the Source of an Illicit Discharge Once an illicit discharge has been confirmed, follow up procedures are performed to track the discharge to its source, including but not limited to: • Record Reviews. Inspections. Monitoring. 7.7.3.1 Record Reviews CMSWS staff reviews available records and information to assist in the identification of potential pollution sources, including digital information available through EDMS and the Mecklenburg County Property Ownership Land Records Information System (POLARIS) as well as other available data sources. The GIS capabilities of EDMS are a valuable component of this review process. 70 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 7.7.3.2 Inspections An on -site inspection is conducted of the area, including upstream and upstream of the confirmed illicit discharge to identify the source. During these inspections, visible observations are often the best technique for source confirmation. In some cases, visual observations will isolate the discharge to a storm drain or sanitary sewer system. It is then necessary to inspect these systems to identify the specific source of the discharge. Standardized methods for source identification are often employed during these inspections, including but not limited to dye testing, smoke testing, and pipe videos. 7.7.3.3 Monitoring If inspections and visual observations are unsuccessful at identifying the pollution source, water quality monitoring techniques are typically employed. Staff typically use field monitoring equipment such as a YSI Multiprobe to perform this monitoring provided the pollutant can be tracked with a parameter measured by the unit, including pH, temperature, dissolved oxygen, conductivity, and turbidity. If laboratory analyses are required to identify the pollution source, the parameters selected are dependent on the suspected source. This can include fecal coliform bacteria for a suspected sewer discharge, total petroleum hydrocarbons (TPH) for a fuel leak, and toxic metals and organics for an industrial discharge. Whether the YSI Multiprobe unit is used or laboratory samples collected, the objective with monitoring is to continually narrow the search area until the source is confirmed. 7.7.4 Procedures for Removing the Source of the Illicit Discharge Once the source of an illicit discharge has been confirmed, investigative activities will be conducted by CMSWS staff for eliminating the source and stopping the discharge. This process may include the issuance of a written notice of the violation for the applicable Stormwater Pollution Control Ordinance (see Section 7.5) to the party responsible for the discharge. The notice requires that the responsible party discontinue the discharge, take action to prevent recurrence, and restore all impacted areas. Staff conducts follow up activities to ensure compliance. Failure to comply could result in the assessment of civil penalties. The use of form letters and shell documents are included in the process. 7.7.5 Documentation CMSWS uses Cityworks' Service Request and/or Activity Report forms to track all investigations and document the following: 1. Date(s) the illicit discharge was observed. 2. Results of the investigation. 3. Notices of violation issued, and enforcement actions taken. 4. Chronic violators for initiation of actions to reduce noncompliance. 5. Storm sewers inspected and dry weather flows identified. 6. Follow-up investigations. 7. Date the investigation was closed. 71 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services All documentation is reviewed and approved by a Supervisor prior to being closed in the system. GIS is integrated into the Cityworks database thus adding a very useful spatial component to data entry and retrieval. This is illustrated in Figure 12, which is a screen shot from Cityworks showing the locations of the 225 notices of violation issued in Mecklenburg's Phase II jurisdictions from July 1, 2020 to June 30, 2022. Data is available for each location with a click of the mouse over the dot. Many search options are available in Cityworks using this information. The application is also available for use in the field using a mobile device.

This outreach campaign includes instructions for properly reporting these problems to CMSWS. Television and radio ads, as well as social media, handouts and brochures are the primary outreach mechanisms. Handouts and brochures have been developed and are typically distributed during the performance of facility inspections, when responding to citizen request for service, and at event displays. This public outreach campaign 72 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services for the IDDE Program is conducted by an Environmental Specialist III with CMSWS and is included as a component of the Outreach Program described in Section 5.4. Problem businesses and industries that have a history of illicit discharges are informed of the threat to the environment from these discharges as well as the requirements of the Stormwater Pollution Control Ordinance(s) through the use of "Environmental Notices." These notices are distributed by staff when responding to citizen requests for service, conducting facility inspections and performing other field activities. At a minimum of once during each five (5) year Permit term, CMSWS provides training to appropriate municipal staff, who, as part of their normal job responsibilities, may come into contact with or otherwise observe an illicit discharge or illicit connection to the storm sewer system. This training informs staff of the threat to the environment from these discharges and the proper reporting process as well as the requirements of the Stormwater Pollution Control Ordinances. By February 16, 2022, field staff in the following Mecklenburg County programs were requested to complete this training: Air Quality, Code Enforcement, Solid Waste, Environmental Health, Social Services, Parks and Recreation, GIS, Assessor Office, and the Sheriff's Office. The following employees at the Towns, CPCC and CMS were requested to complete this training: maintenance workers, firefighters, policemen, public works and utility workers, and parks and recreation. During the permit term, 393 employees in the above departments and towns completed this training. This satisfied the IDDE municipal staff training requirement for the Permit term ending February 16, 2022. The second round of training will be completed prior to end of the next Permit term on February 20, 2027. 7.9 Decision Process The IDDE Program for the Mecklenburg County Phase II jurisdictions/entities rely primarily on public involvement and participation as well as data collected through water quality monitoring activities and field investigations to identify priority areas for illicit discharges. Standardized follow up field screening activities are employed in these identified priority areas to confirm pollution sources, which are eliminated through the enforcement of the local Stormwater Pollution Control Ordinances. The decision process followed in the development of this approach included an examination of techniques used successfully in the past by CMSWS for the identification and elimination of pollution sources as part of the City of Charlotte's Phase I Program. Public involvement has always played a key role in the identification of problem areas. The outreach campaign included as part of the program is designed to increase public awareness of water quality issues and inform them of the correct process for reporting suspected pollution problems. CMSWS water quality monitoring activities have been performed in the Phase II jurisdictions for over 25 years and they have proven successful at identifying water quality problem areas. This ongoing monitoring effort was expanded for the Phase II Permit. This expanded monitoring program includes the use of continuous automated water quality monitoring equipment. Water quality monitoring data is summarized using the Stream Use Support Index or SUSI at least quarterly and is used by CMSWS staff to target/direct pollution control activities. 73 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER �—� S.MceS Another tool that has proven effective in the implementation of Charlotte's Phase I Program and thus has been applied in the Phase II Program areas is the enforcement of local Stormwater Pollution Control Ordinances. CMSWS has found these ordinances to be an effective tool for the elimination of pollution sources and for deterring future violations. The storm sewer mapping effort has assisted in the implementation of the IDDE Program by providing a thorough examination of the inlets and outlets to the MS4s as well as identifying dry weather flows, both of which have led to the elimination of pollution sources. The availability of storm sewer maps and other data in GIS through the Cityworks database has facilitated the tracking of discharges to their source. The selection of CMSWS staff for the execution of the measurable goals associated with the IDDE Program is based on their familiarity with the identification and elimination of pollution problems as well as their expertise in the enforcement of pollution control ordinances. 7.10 Program Evaluation The measurable goals for each BMP are described in Table 18. The overall success of the IDDE Program is evaluated through the successful achievement of these measurable goals as reported with each NPDES MS4 annual assessment report. At a minimum, the following metrics are included in this annual report: • Number of inlets and outlets identified. • Types of water quality monitoring performed, and summary of criteria exceeded. • Number of field screenings completed for non-stormwater flows. • Number of illicit discharges detected and eliminated. Other measures of success for the IDDE Program are described below. • Documentation of Stormwater Program Activities — As a baseline measure of success, staff will document the completion of Work Plan activities that demonstrate the successful fulfillment of the BMPs associated with this program element. All activities will be documented in CMSWS's Cityworks database. • Increasing Pollution Problems Identified — CMSWS will track the ratio of the number of notices of violation issued to the number of IDDE inspections conducted with an increase from the average percentage of the previous three (3) fiscal years serving as an indicator of the success of our efforts to find and eliminate pollution sous. • Repeat Violators Minimized (added in FY2021) — CMSWS will track the percentage of the number of notices of violation issued to repeat violators with a decrease from the average percentage of the previous three (3) fiscal years serving as an indicator of the success of our efforts to reduce the number of repeat offenders. On an annual basis, CMSWS staff will evaluate the BMPs assigned to this program and assess progress toward achieving the measurable goals from Table 18 and the measures of success described above. Recommendations for improvement will be made as necessary. During the following fiscal year, program activities and BMPs will be modified as necessary based on the results of this evaluation in order to ensure that the specific goals and objectives of the IDDE Program and SWMP are being effectively and efficiently fulfilled. 74 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER rl\ Services SECTION 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM Construction Site Runoff Control Programs have been developed and are currently being implemented for addressing the discharge of sediment and other pollutants from construction sites in Mecklenburg County 's Phase II jurisdictions that disturb one or more acres of land surface and those activities less than one acre that are part of a larger common plan of development as authorized under the Sediment Pollution Control Act of 1973. These are delegated programs under NCGS I I3A-60. CMSWS's Permitting and Compliance Program administers the program for the County and Towns of Davidson, Cornelius, Matthews, Mint Hill, and Pineville. In November 2019, the Town of Huntersville received delegated authority from the State to administer a local erosion control program in their jurisdiction. The Town of Huntersville coordinates with the County in the completion of the activities associated with the Construction Site Erosion Control Program described in this Section. Kevin Fox, Public Works Director, serves as the responsible party for compliance with the Permit requirements for the Construction Site Storm Water Runoff Control Program in the Town of Huntersville. His contact information is as follows: 704-766-2220 and kfox(d),huntersville.org. 8.1 Program Goals and Objectives CMSWS's establishes its goals and objectives for its Construction Site Runoff Control Program, which are evaluated and updated annually as necessary, based on the actions necessary to effectively address the targeted pollutants and pollutant sources identified in Table 9. The current goal of the Construction Site Runoff Control Program is to reduce pollutants in stormwater runoff from construction activities that result in a land disturbance of greater than or equal to one acre. Construction activities disturbing less than one acre are included in the program if they are part of a larger common plan of development or sale that would disturb one acre or more. The current objectives of the program are as follows: 1. Implement and enforce a program to ensure the proper permitting, installation and maintenance of erosion control measures in compliance with local ordinances as well as the N.C. Sediment Pollution Control Act of 1973 and Chapter 4 of Title 15A of the North Carolina Administrative Code. 2. Ensure the proper control of waste at construction sites to prevent illicit discharges and negative impacts to surface water quality, including but not limited to discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste. 3. Provide and promote a means for the public to notify the Permitting and Compliance Program of observed erosion and sedimentation problems. 4. Educate contractors, developers and others engaged in land disturbing activities in the proper methods for installing and maintaining erosion control measures and preventing pollutants from discharging from construction sites. 8.2 BMP Summary Table Table 19 describes the BMPs implemented as part of the Construction Site Runoff Control Program. 75 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Table 19: BMP Summary Table for the Construction Site Stormwater Control Proj4ram A B I C D E County County Activities BMP No. Work Plan Code Description of BMP Measurable Goal(s) Schedule for Implementation Annual Reporting Metric Co-Permittee Responsibilities Construction Site Runoff Control Program (Permit Ref.

The delegated Sediment and Erosion Control Program effectively meets the MEP standard for Construction Site Runoff Controls by permitting and controlling development activities disturbing one or more acres of land surface and those activities less than one acre that are part of a larger common plan of development as authorized under the Sediment Pollution Control Act of 1973 and Chapter 4 of Title 15A of the North Carolina Administrative Code. The regulatory mechanism established for this program is the Mecklenburg County Soil Erosion and Sedimentation Control Ordinance effective October 21, 1974 and amended 14 times as follows: March 5, 1979, June 16, 1980, April 2, 1984, October 7, 1985, February 27, 1986, April 21, 1987, December 7, 1987, February 4, 1991, May 10, 1993, February 7, 1995, June 3, 1997, September 6, 2000, May 21, 2002, and October 7, 2008. The County's ordinance is currently enforced by the Permitting and Compliance Program in the Towns of Cornelius, Pineville and Matthews. The Towns of Davidson and Mint Hill have their own sediment and erosion control ordinances, which are very similar to Mecklenburg County's and are also enforced by the Permitting and Compliance Program. The Town of Huntersville has a similar ordinance that it enforces. These ordinances require an approved Erosion Control Plan for construction activities that result in the disturbance of greater than or equal to one acre of land. The ordinances further require that all construction site operators implement appropriate erosion and sediment control BMPs, including those sites that disturb less than an acre. Copies of the ordinances are available at the following website: hgp:Hstormwater.charmeck.org (select "Regulations", select jurisdiction, select "Soil Erosion and Sedimentation Control"). The Mecklenburg County Soil Erosion and Sedimentation Control Policies and Procedures describe how ordinances are enforced and the local program is implemented, including inspection procedures, record keeping requirements, form letters for notices of violation, and enforcement guidance. A copy of these policies and procedures is available upon request to the Environmental Manager for Mecklenburg County's Water Quality Program. The Surface Water Pollution Control Ordinances (see Section 7.5) are used to regulate pollutants other than sediment that are generated from construction sites and have the potential to negatively impact water quality such as discarded building material, concrete truck washout, chemicals, litter, and sanitary waste. Staff inspecting for compliance with soil erosion and sediment control ordinance also inspect for compliance with the pollution control ordinance. 77 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 8.4 Erosion Control Plan Reviews Section 6(b) of the erosion control ordinances for Mecklenburg County and the Town of Huntersville as well as Sections 19.6(b) and 6.7.6(B) of the ordinances for the Towns of Davidson and Mint Hill, respectively, require an approved Erosion Control Plan for construction activities that result in the disturbance of greater than or equal to one acre of land. Erosion control inspectors conduct a site plan review and on -site inspection prior to plan approval. Sections 10, 19.10 and 6.7.10 of the respective erosion control Ordinances specify the content of the plan, which includes all BMPs planned for the control of erosion and sedimentation. Staff with CMSWS's Permitting and Compliance Program reviews all Erosion Control Plans for the Phase II jurisdictions in Mecklenburg County, except for in the Town of Huntersville where their staff performs these reviews and government projects which are reviewed by NCDEQ staff. Reviews are typically completed within 30 days of submittal and the person submitting the plan is notified as to whether the plan is approved, approved with modifications, or disapproved. The applicant has the right to appeal the disapproval before the Charlotte -Mecklenburg Stormwater Advisory Committee. Plan approval is considered void if land disturbing activities do not commence within three (3) years of the approval date. The Mecklenburg County Soil Erosion and Sedimentation Control Policies and Procedures describe the process for site plan review, which incorporates consideration of potential water quality impacts. 8.5 Enforcement Sections 13, 19.13 and 6.7.13 of the respective erosion control Ordinances specify that any person who violates any of the provisions of the ordinance is subject to a civil penalty in an amount not to exceed $5,000 per day for each day the violation continues. The Permitting and Compliance Program has established guidance in its policies and procedures for setting penalty amounts for different types of violations. The Stormwater Advisory Committee (SWAC) hears appeals to enforcement actions. The Mecklenburg County Soil Erosion and Sedimentation Control Policies and Procedures describe the enforcement process, including procedures for issuing notices of violation, assessing penalties and handling appeals. 8.6 Inspections All erosion and sedimentation control inspections in the Phase II jurisdictions are performed by staff of the Permitting and Compliance Program, except for in the Town of Huntersville and its ETJ where their staff performs these inspections and government projects which are inspected by NCDEQ staff. Following plan approval but prior to initiating land disturbing activities and issuance of a local grading permit, staff conducts a pre -construction meeting involving all parties associated with the land disturbing activity to ensure that everyone is familiar with the approved Erosion Control Plan and ordinance requirements. The construction site is evaluated during this pre -construction meeting and a checklist completed. Following the pre -construction meeting, erosion control measures are installed by the contractor after which the Permitting and Compliance Program conducts an inspection to confirm proper installation in accordance with the approved Erosion Control Plan and ordinance requirements. Following this confirmation, the inspector issues a local grading permit authorizing grading of the site. Once grading activities commence, staff perform compliance inspections on a routine interval based on an established 90. Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services prioritization scheme. If inspections reveal noncompliance with the approved Plan or other ordinance violations, a written or verbal notice of violation is issued identifying the violation(s) and specifying the specific action(s) needed to ensure compliance. Follow up inspections are conducted to verify compliance after which penalties may be assessed depending on the nature of the violation and effectiveness of the response. The Mecklenburg County Soil Erosion and Sedimentation Control Policies and Procedures describe the inspection process and include inspection logs and checklists. 8.7 Erosion Control Hotline Mecklenburg County provides a means for the public to notify the Permitting and Compliance Program of observed erosion and sedimentation control problems in the Phase II jurisdictions through contacting the 311 helpline as described in Section 5.3. This reporting mechanism is promoted through the media campaign conducted as part of the Public Education and Outreach Program. Staff conducts follow up investigations on reported problems and initiates the actions necessary to ensure proper erosion and sedimentation control and the protection of water quality. 8.8 Erosion Control Education The Permitting and Compliance Program with CMSWS provides erosion control education through its "Charlotte Mecklenburg Certified Site Inspector" (CMCSI) course, which includes six (6) hours of training on proper erosion and sedimentation control and a written test. Section 8(f), 19.8(f) and 6.7.8(F) of the of the respective erosion control Ordinances specify that persons conducting land -disturbing activities, or their agent perform inspections of all erosion and sedimentation control measures at least once a week and within 24 hours after any storm event of greater than 0.5 inch of rain (except Huntersville that uses 1 inch) per 24-hour period. Local policies and procedures state that the person performing these inspections must be certified and technically competent and that a self -inspection log must be maintained. Satisfactorily completing the CMCSI training qualifies a person to perform these activities. 8.9 Government Projects All government projects within the Phase II jurisdictions are regulated by NCDEQ's Erosion and Sediment Control Program, which conducts plan reviews, inspections and enforcement activities. This includes construction activities performed directly by the Phase II entity or by a company under contract with the entity. 8.10 Decision Process Construction site pollutants have been successfully controlled in the Phase II jurisdictions through a locally delegated program for almost 50 years. The Phase II jurisdictions have elected to continue their reliance on this local program due to its past successes and the improvements recently brought about through program modifications. 8.11 Program Evaluation 79 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER Services The measurable goals for each BMP are described in Table 19. The overall success of the Construction Site Runoff Control Program is evaluated through the successful achievement of these measurable goals as reported with each NPDES MS4 annual assessment report. At a minimum, the following metrics are included in this annual report: • Number of new projects permitted. • Number of acres disturbed. • Number of erosion control inspections conducted. • Number of notices of violation issued. • Number of penalties assessed. • Description of educational activities completed. Other measures of success for the Construction Site Runoff Control Program are described below. • Documentation of Stormwater Inspection Activities: As a baseline measure of success, staff will document completion of inspection activities in CMSWS's Cityworks database. • Improving CoMpliance: CMSWS will track the ratio of the number of notices of violation issued to erosion control inspections conducted with a decrease from the previous fiscal year serving as an indicator of success. On an annual basis, the Permitting and Compliance Program will evaluate the BMPs assigned to this program and assess progress toward achieving the measurable goals from Table 19 and the measures of success described above. Recommendations for improvement will be made as necessary. During the following fiscal year, program activities and BMPs will be modified as necessary based on the results of this evaluation in order to ensure that the specific goals and objectives of the Construction Site Runoff Control Program and SWMP are being effectively and efficiently fulfilled. Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services SECTION 9: POST -CONSTRUCTION SITE RUNOFF CONTROL PROGRAM A Post -Construction Site Runoff Control Program has been developed and is currently being implemented for addressing post -construction stormwater runoff from new development and redevelopment projects in Mecklenburg County's Phase II jurisdictions. The program is administered by CMSWS's Water Quality and Permitting and Compliance Programs as described in the following Sections except for in the Town of Huntersville and its ETJ where effective July 1, 2020 Town staff are responsible for plan reviews and issuing land development Permits as well as conducting inspections to confirm project completion in compliance with Permit requirements. Kevin Fox, Public Works Director, serves as the responsible party for compliance with the Permit requirements for the Post -Construction Site Runoff Control Program in the Town of Huntersville. His contact information is as follows: 704-766-2220 and kfoxnhuntersville. org. 9.1 Program Goals and Objectives CMSWS's establishes its goals and objectives for its Post -Construction Site Runoff Control Program, which are evaluated and updated annually as necessary, based on the actions necessary to effectively address the targeted pollutants and pollutant sources identified in Table 9. The current goal of the Post -Construction Site Runoff Control Program is to prevent or minimize negative water quality impacts during post -construction conditions at new developments and redevelopments, including public transportation maintained by the permittee. The current objectives of the program are as follows: 1. Implement and enforce a program to address stormwater runoff from new development and redevelopment projects, including public transportation maintained by the permittee, that disturb greater than or equal to one (1) acre, including projects disturbing less than one (1) acre that discharge to the storm sewer system. 2. Implement strategies which include a combination of structural and/or non-structural BMPs appropriate for the community. 3. Use an ordinance or other regulatory mechanism to address post -construction runoff from new development and redevelopment projects. 4. Ensure adequate long-term operation and maintenance of BMPs. Achievement of this objective will be measured by a reduction in the number of noncompliant BMPs over time (see Section 9.13). 9.2 BMP Summary Table Table 20 describes the BMPs implemented as part of the Post -Construction Site Runoff Control Program.

These regulations meet or exceed the minimum requirements for the control of post -construction stormwater runoff specified by 40 Code of Federal Regulations 122.34(b)(5) (1 July 2003 Edition). These regulations meet the objectives of the Post -Construction Site Runoff Control Program and provide the authority to: 1. Review designs and proposals for new development and redevelopment to determine whether adequate stormwater control measures will be installed, implemented, and maintained. 2. Request information such as SWMPs, inspection reports, monitoring results, and other information deemed necessary to evaluate compliance with the Post -Construction Stormwater Management Program. 3. Enter private property for the purpose of inspecting at reasonable times any facilities, equipment, practices, or operations related to stormwater discharges to determine whether there is compliance with the Post -Construction Site Runoff Control Program. Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Administrative and BMP Manuals have been developed and are being maintained by CMSWS to guide the implementation and enforcement of ordinance requirements. The Administrative Manual includes application requirements, forms, submission schedules, fee schedules, maintenance plans and agreements, criteria for mitigation approval, criteria for recordation of documents, inspection report forms, requirements for submittal of bonds, and other information and forms used in the administration of the post -construction ordinances. The BMP Manual includes the designs for structural stormwater controls as well as methods for calculating built - upon area and other information used in the construction of BMPs required by the ordinances. Copies of the ordinances as well as the Administrative and Design Manuals, design standards checklist, and other materials appropriate for developers are available at the following website: http:Hstonnwater.charmeck.org (select "Regulations", select jurisdiction). CMSWS's Environmental Manager for the Water Quality Program serves as the Stormwater Administrator responsible for the implementation and enforcement of the post -construction ordinances for the Towns and County except for the Town of Cornelius, which uses its Planning Director to fulfill this role. All appeals and variances are heard by the Charlotte -Mecklenburg Stormwater Advisory Committee (SWAC), very similar to the process used for the Sediment and Erosion Control Program described in Section 8. The only exceptions are that the Towns of Cornelius and Huntersville use their Boards of Adjustment to hear all appeals and variances. Implementation of the post -construction ordinances consists of the following activities: 1. Maintaining and updating the ordinances as necessary. 2. Providing interpretations regarding the applicability of ordinance requirements to new developments and redevelopments. 3. Maintaining and updating the Charlotte -Mecklenburg BMP Design Manual as necessary. 4. Maintaining and updating the Administrative Manual as necessary. 5. Performing site plan reviews of all new development and redevelopment projects that disturb greater than or equal to one acre (including sites that disturb less than one acre that are part of a larger common plan of development or sale) and performing reviews on new development and redevelopment that disturb less than an acre as required by specific ordinance requirements. The site plan review addresses how the project meets the performance standards and how the project will ensure long-term maintenance. 6. Conducting site inspections during construction to ensure compliance with approved plans and all ordinance requirements. 7. Conducting a post -construction inspection before issuing a certificate of occupancy to verify that performance standards have been met or a bond is in place to guarantee completion. 8. Inspection findings and enforcement actions will be documented, and records maintained. Notices of violation and enforcement actions will be tracked, and a reporting mechanism established to identify chronic violators for initiation of actions to reduce noncompliance. 9. Maintaining an inventory of public and private projects with BMPs installed for compliance with post -construction ordinance requirements. 10. Ensuring that mechanisms are in place to guarantee that projects will be maintained consistent with approved plans in compliance with ordinance requirements. 11. Ensuring the implementation of long-term operation and maintenance plans for structural BMPs in accordance with ordinance requirements, including ensuring that the owner of HIM Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services each structural BMP has a qualified professional perform annual inspections and maintains records of these inspections. 12. Conducting site inspections of structural stormwater controls installed for compliance with ordinance requirements at least once during the Permit term. Records of inspection findings and enforcement actions are maintained in the Cityworks database. Notices of violation and enforcement actions are tracked and used to identify chronic violators for initiation of actions to reduce noncompliance. 13. Implementing a program to educate the development community and the general public concerning the post -construction stormwater management requirements. Ordinances, post -construction requirements, design standards checklist, and other materials appropriate for developers are made available through paper or electronic means. 9.4 Compliance by Co-Permittees with Post -Construction Ordinance Requirements New developments constructed by or under contract with the Phase II entities are required to comply with the local post -construction ordinance requirements adopted by the jurisdiction where the project is located, including the City of Charlotte, Mecklenburg County, and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill, and Pineville. New roads and road expansions interior to land development projects required to comply with post -construction requirements must adhere to these same requirements regardless of whether these roads will be privately maintained or maintained by the jurisdiction. For such projects, the built -upon area for the roads is incorporated into the built -upon area for the project and BMPs are installed as necessary to comply with ordinance requirements. There are a few exceptions to compliance with local post -construction requirements for other types of transportation projects as described in Appendix C. CMSWS maintains a current inventory of the structural SCMs owned and/or operated by the Phase II jurisdictions/entities that were installed for compliance with Post -Construction Ordinances. This inventory is available upon request to the Storm Water Administrator. The Phase II jurisdictions/entities maintain and implement O&M Plans for these SCMs, which specify the frequency of inspections and routine maintenance requirements. The Phase II jurisdictions/entities inspect and maintain their SCMs in accordance with the schedule contained in the O&M Plan. Plans vary based on SCM type. Sample O&M Plans are available upon request. To ensure that all structural SCMs are being maintained pursuant to their O&M Plan, all co-permittees conduct annual inspections of the SCMs that they own and/or operate using a qualified professional. A qualified professional is either a qualified NC professional engineer or registered landscape architect performing services only in their area of competence, or someone who has a valid Stormwater SCM Inspection & Maintenance Certification from NC State University. All inspections of SCMs are documented on an inspection form and submitted to the Storm Water Administrator for review and follow up as necessary. These forms are available at the following link: hgps://mecklenbur cg ounty.exavault.com/p/waterquality/PCO%2OForms/BMP_Maintenance_Ins pection_Checklists _PCO21/. For Charlotte -Mecklenburg Schools, Central Piedmont Community College, and the Towns, these inspections are performed by CMSWS staff. Inspections of County owned facilities are the responsibility of the Department that manages the Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services facility where the SCM is located, including Asset and Facility Management, Park and Recreation and the Sheriff's Department. 9.5 Requirements for Non -Structural BMPs The post -construction ordinances include stream buffer and undisturbed open space requirements as summarized in Table 21, which serve as non-structural BMPs. Prior to the adoption of the post -construction ordinances, non-structural stormwater controls were in effect in the Phase II jurisdictions that continue to apply, including zoning ordinances to direct growth to identified areas. In addition, Mecklenburg County's Park and Recreation Department actively acquires and maintains open space for parks and nature preserves. This program concentrates on preserving environmentally sensitive and natural resource areas within the County, including wetlands and riparian buffers.

(3) Buffer also includes 100% of the floodplain and is undisturbed. Since 1999, buffers ranging in width from 35 feet to the entire FEMA floodplain have been required along perennial streams in the Phase II jurisdictions. These buffer requirements were implemented as part of Mecklenburg County's Surface Water Improvement and Management (S.W.I.M.) Program. The northern Towns of Cornelius, Davidson and Huntersville have portions of their jurisdictions in WS-IV watersheds and have maintained water supply watershed rules in their zoning ordinances since the mid-1990s. These rules require buffers ranging from 50 to 100 feet in width along the lake shoreline as well as along perennial streams delineated on USGS quadrangle maps. HIM Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 9.6 Requirements for Structural BMPs The post -construction ordinances adopted on June 30, 2007 by the Phase II jurisdictions contain requirements for the installation of structural BMPs to control and treat stormwater runoff to meet specific volume, peak and water quality requirements when a built -upon area threshold is reached. These BMPs must meet the design criteria contained in the Charlotte -Mecklenburg BMP Design Manual. This manual includes design criteria for the following types of BMPs: bioretention, wet pond, stormwater wetland, enhanced grass swale, grass channel, infiltration trench, filter strip/woody buffer strip, sand filter, extended dry detention, and proprietary BMPs. The design volume of the BMPs takes into account the runoff at buildout for on -site improvements and the maximum low -density option for off -site areas from all surfaces draining to the structure. BMPs are sized to treat and control stormwater runoff from all surfaces draining to the structure, including streets, driveways, and other built -upon area. Table 22 provides a general summary of the structural BMP requirements.

(2) A combination of LID and conventional stormwater treatment measures is allowed in the form of a treatment train. (3) Water quality treatment systems that promote the infiltration of flows and groundwater recharge (LID) shall be used unless it can be demonstrated that such treatment systems are not a practical alternative for the site. Prior to the adoption of the post -construction stormwater ordinances, the installation of structural stormwater controls was required for developments and redevelopments located in the WS-IV watersheds in the Towns of Davidson, Cornelius and Huntersville. In addition, beginning on July 2, 1979 the Phase II jurisdictions required the submission and approval of a drainage plan for land development activities that involved the cumulative creation of more than 20,000 square feet of impervious ground cover. This requirement is typically applied to commercial development but could be applied to residential development at the election of the Town. If the impervious cover proposed in the plan increased the peak level of stormwater runoff from the site, then the plan was required to identify measures to control and limit runoff to peak flows no greater than would occur from the site if impervious area were not increased for the 2-year and 10-year storm events. BMPs installed for compliance with the WS-IV watershed ordinances and Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services those BMPs installed for the July 2, 1979 drainage plan requirements are not subject to the post - construction ordinance requirements for inspection and maintenance. In addition, BMPs installed for compliance with Huntersville's LID Ordinance prior to June 30, 2007 are not subject to these requirements. 9.7 Natural Resource Protection The Division of Nature Preserves and Natural Resources within the Mecklenburg County Park and Recreation Department is responsible for the protection and conservation of Mecklenburg County's parks designated as Nature Preserves. Mecklenburg County's nature preserves protect the county's biological resources and natural areas, while providing opportunities for environmental education, nature -based programs, and outdoor recreation. The Division of Nature Preserves and Natural Resources offers more than 5,000 programs annually, performs natural resource management on over 7,400 acres, maintains more than 30 miles of nature trails, and operates 3 nature centers and a public campground. 9.8 Open Space Protection As described in Section 9.5 above, the post -construction ordinances for Mecklenburg County and the Towns of Davidson, Matthews, Mint Hill, and Pineville require open space preservation based on project area as described in Table 21. Failure to adequately protect these open space areas constitutes a violation of the ordinance, which is subject to fines. The Towns of Cornelius and Huntersville have open space requirements as a Section of their land development code, but these requirements are not enforced as a component of the post -construction ordinance. 9.9 Tree Preservation To varying degrees, the Phase II jurisdictions in Mecklenburg County require the planting of additional trees to enhance the urban tree canopy as well as the protection and maintenance of trees on public and private property. Street trees are also required. These requirements are generally contained in Land Development or Zoning Ordinances. 9.10 Green Infrastructure Practices The post -construction stormwater ordinances adopted by the Phase II jurisdictions contain the following green infrastructure practices: 1. The use of vegetated conveyances for the transport stormwater to the MEP. 2. The optional use of permeable pavement systems as a structural BMP to help manage stormwater runoff. 3. The optional use of green roofs as structural BMPs to help manage stormwater runoff. 4. The optional use of consultation meetings early in the development review process to discuss the post -construction stormwater management measures necessary for the proposed project, as well as to discuss and assess constraints, opportunities and potential approaches to stormwater management designs before formal site design engineering is commenced. Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER ��, Services 5. The designation of undisturbed open space areas ranging from 10% to 25% of the total project area based on the jurisdiction (except in Cornelius and Huntersville) (see Table 21). 6. The protection of buffers ranging in width from 30 feet to the entire FEMA floodplain depending on the watershed area and jurisdiction (see Table 21). 7. The optional use of low impact development techniques except in the Town of Huntersville and Goose Creek watershed where it is required (see Table 22). 8. The optional use of payment -in -lieu as well as off -site and on -site mitigation to satisfy post -construction stormwater ordinance requirements in cases where on -site alternatives are not technically feasible. These options provide money for tree planting, open space acquisition, installation of off -site BMPs, etc. Practices are in place to ensure the long-term maintenance of green infrastructure, including recording the infrastructure on final plats at the Mecklenburg County Register of Deeds Office and performing periodic inspections. 9.11 Operation and Maintenance The Phase Il jurisdictions have included requirements in their post -construction programs to ensure the adequate long-term operation and maintenance of structural and non-structural BMPs as summarized below. 1. A BMP Operation and Maintenance Agreement and Declaration of Covenants must be completed and recorded at the Mecklenburg County Register of Deeds Office for all structural BMPs. A BMP Maintenance Plan must be included as an addendum to this agreement. This is a binding legal agreement prepared using the format provided by the Stormwater Administrator that specifies the responsibilities for performing BMP maintenance and provides a description of the maintenance activities to be performed, including a schedule. In addition, the following language must be included on the final plat for all developments and redevelopments subject to post -construction ordinance requirements: "This property contains water quality features that must be maintained according to the Operations and Maintenance Agreement and Plan recorded in Deed Book and Page " 2. As -built plans are required that show the final design specifications for all structural BMPs and the field location, size, depth, and planted vegetation associated with the BMP as installed, as well as the location and size of all undisturbed open space areas and tree plantings. The designer of the stormwater management measures and plans must certify, under seal, that the as -built stormwater measures, controls, and devices are in compliance with the approved plans and designs and with the requirements of the post -construction ordinance. 3. Maintenance and access easements must be established and recorded on the final plat for all BMPs except those installed for public facilities. 4. The location and dimensions of all BMPs must be included on the final plat recorded at the Mecklenburg County Register of Deeds Office. The following language must be included on the final plat: "The purpose of the BMP is to treat/reduce the pollutants associated with stormwater runoff in order to minimize negative effects to downstream receiving waters. The easement around the BMP is to allow stormwater conveyance and all Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services system maintenance. The removal of plants or disturbance of the BMP structure or otherwise affecting the overall functionality of the BMP for reasons other than maintenance is strictly prohibited." 5. The location of undisturbed open space must be included on the final plat recorded with the Mecklenburg County Register of Deeds Office. The following language must be included on the final plat: "Undisturbed Open Space Area: Future disturbance is prohibited in these areas except for greenway trails with unlimited public access, new Charlotte -Mecklenburg Utility lines and channel work/maintenance activities by Charlotte -Mecklenburg Stormwater Services." 6. The location of water quality buffers must be included on the final plat recorded with the Mecklenburg County Register of Deeds Office. The top of the stream bank must be field located and shown on the plat. Each buffer zone must also be shown on the plat and the stream side zone must be labeled as "UNDISTURBED." 7. If requested by the owner, Mecklenburg County and all the Towns except Cornelius and Huntersville will accept the maintenance responsibility for structural BMPs that are installed pursuant to the post -construction stormwater ordinance following a warranty period of two (2) years from the date of the final approval of the BMP, provided the BMP: Serves a single-family detached residential development or townhomes all of which have public street frontage. Is satisfactorily maintained during the two-year warranty period by the owner or designee. Meets all the requirements of the applicable post -construction stormwater ordinance and the Design Manual. • Includes adequate and perpetual access and sufficient area, by easement or otherwise, for inspection, maintenance, repair, or reconstruction. The maintenance of all BMPs not covered by this provision is the responsibility of the owner or their designee. 8. The Towns, Mecklenburg County, CMS and CPCC will maintain the BMPs that they install for their respective projects when they retain ownership. An O&M Plan has been developed for this maintenance and is available upon request. 9. BMP Maintenance Bonds are required for all structural BMPs installed for both residential and commercial developments. BMP Maintenance Bonds are not required for BMPs installed for public facilities. The purpose of these bonds is to ensure that funds are available to maintain BMPs if the owner should fail to do so in which case the Town or Mecklenburg County would cash the bond to obtain the money to perform the necessary maintenance. The bonds must be posted by the owner for a period of not less than two (2) years from the as -built approval date. 10. All BMPs installed for compliance with post -construction stormwater ordinance requirements must be inspected at a minimum of annually. The owner of the BMP is responsible for ensuring that these inspections are performed, and for the submittal of the necessary documentation to CMSWS. They are also responsible for correcting all BMP violations. In all the jurisdictions except the Town of Huntersville, BMPs must be inspected by a qualified registered N.C. professional engineer or landscape architect at a minimum of annually. In Huntersville, a "qualified professional" is authorized to inspect these BMPs. The minimum requirements for a qualified professional and the established 91 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services process for verifying these qualifications are contained in the post -construction ordinance Administrative Manual available on the website. The Stormwater Administrator has developed BMP inspection forms that are also available on this website. 11. All low -density projects are required to indicate built -upon area restrictions for the development on a plat. Upon completion of development, as-builts are required to verify compliance with these restrictions. County and/or Town staff review and approve these as-builts and the plat, which is subsequently recorded at the register of deeds office, to ensure compliance with these restrictions before bonds and/or project holds are released. Prior to the issuance of future building permits for additional development at the site, verification must be provided to staff that the established built -upon area restriction is not being exceeded as a result of the new development. CMSWS's interpretation is that this system satisfies the permit condition for ensuring the inspection and maintenance of low - density projects. 9.13 Decision Process Between April 2004 and September 2005, a stakeholders' group deliberated in the development of a draft post -construction ordinance for Charlotte -Mecklenburg. The resulting consensus document was subsequently reviewed and modified as necessary by the Phase II jurisdictions to meet their specific requirements. These documents were submitted to NCDEQ and following approval were adopted into law effective June 30, 2007. Following adoption, workshops were held for the development community and staff to help ensure effective implementation. It was decided that a stakeholders' process would be used in the development of the post -construction ordinance based off the successes of previous such efforts. For example, CMSWS relied on a similar approach in the development of the S.W.I.M. stream buffer ordinances and local water supply watershed rules. During the development of the draft post -construction ordinances, efforts were undertaken to conform these rules to each jurisdiction's specific water quality needs. For example, the Towns of Matthews, Mint Hill and Pineville have streams within their jurisdictions identified on the N.C. 303(d) list for fecal coliform bacteria and TMDLs have been developed. In addition, Goose Creek in the Town of Mint Hill is an identified habitat for the Carolina heelsplitter, a federally endangered species of freshwater mussel. The Towns in northern Mecklenburg County have similar challenges. McDowell Creek in Huntersville and Cornelius as well as Long Creek and Clarke Creek in Huntersville and the Rocky River in Davidson are identified on the N.C. 303(d) list for biological impairment, fecal coliform bacteria and/or turbidity. These are all high priority issues that were taken into consideration during the stakeholder process for development of the post -construction ordinances for the Phase II jurisdictions. 9.14 Program Evaluation The measurable goals for each BMP are described in Table 20. The overall success of the Post - Construction Site Runoff Control Program is evaluated through the successful achievement of these measurable goals as reported with each NPDES MS4 annual assessment report. At a minimum, the following metrics are included in this annual report: Number of new projects permitted. 92 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services • Number of acres disturbed. • Number of structural BMP inspections conducted. • Number of notices of violation issued. • Number of penalties assessed. • Description of educational activities completed. Other measures of success for the Post -Construction Stormwater Runoff Control Program are described below. • Documentation of Stormwater Inspection Activities: As a baseline measure of success, staff will document completion of inspection activities in CMSWS's Cityworks database. • Improving CoMpliance — Structural BMPs installed for compliance with post - construction ordinance requirements will be inspected at a minimum of once a year. CMSWS will also periodically inspect buffers, undisturbed open space and other non- structural BMPs to ensure their long-term effectiveness. CMSWS will track and report the ratio of the number of deficiencies detected compared to the number of BMP inspections conducted with a decrease from the previous fiscal year serving as an indicator of success. On an annual basis, CMSWS staff will evaluate the BMPs assigned to this program and assess progress toward achieving the measurable goals from Table 20 and the measures of success described above. Recommendations for improvement will be made as necessary. During the following fiscal year, the program activities and BMPs will be modified as necessary based on the results of this evaluation in order to ensure that the specific goals and objectives of the Post - Construction Stormwater Runoff Control Program and SWMP are being effectively and efficiently fulfilled. 93 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER rl� services SECTION 10: POLLUTION PREVENTION & GOOD HOUSEKEEPING PROGRAM A Pollution Prevention/Good Housekeeping Program has been developed and is currently being implemented for addressing discharges of pollution from municipal facilities and operations owned and/or operated by Mecklenburg County's Phase II jurisdictions. The program is administered by CMSWS's Water Quality Program as described in the following Sections. Each co-permittee is responsible for pollution prevention and good housekeeping at facilities that they own and control. 10.1 Program Goals and Objectives CMSWS's establishes its goals and objectives for its Pollution Prevention/Good Housekeeping Program, which are evaluated and updated annually as necessary, based on the actions necessary to effectively address the targeted pollutants and pollutant sources identified in Table 9. The current goal of the Pollution Prevention/Good Housekeeping Program is to reduce pollutants in stormwater runoff from municipal operations. The current objectives of the program are as follows: 1. Develop and implement an operation and maintenance program to prevent or reduce stormwater pollution from facilities and operations owned and/or operated by the Phase II jurisdictions/entities. 2. Train the employees at these facilities and operations to prevent and reduce stormwater pollution from activities such as park and open space maintenance, fleet and building maintenance, new construction and land disturbances, and stormwater system maintenance. 10.2 BMP Summary Table Table 23 describes the BMPs implemented as part of the Pollution Prevention/Good Housekeeping Program.

These procedures were implemented effective July 1, 2005 and are based on guidelines provided by NCDEQ. These guidelines are contained in Appendix D and include an evaluation of 20 percent of the identified facilities each year for the 5-year Permit term. As new facilities were identified, they were incorporated into the Pollution Prevention/Good Housekeeping Program based on the application of these guidelines. During the second Permit term beginning in 2011, CMSWS updated its SWMP to comply with a new Phase II Permit requirement that properties with a "significant potential for generating polluted stormwater runoff' must be included in an Operations and Maintenance (O&M) Program that specifies a frequency of inspection and routine maintenance requirements. This new requirement was less inclusive than those applied during the first Permit term; therefore, facilities and operations identified for coverage prior to 2011 were left in the program thus going beyond minimum Permit requirements. CMSWS uses the following criteria to determine if a facility has a significant potential for generating polluted stormwater runoff. 1. Exposure of significant materials based on the "Exposure Checklist" included in numbers 12 through 14 of NCDEQ's "No Exposure Certification Form" (NCGNE0000) (see Appendix D) as described in CMSWS's "Form for Evaluating Exposure of Significant Materials" (see Appendix E), and 2. No written procedures or controls in place to prevent pollution. Facilities that meet the above criteria are added to the Pollution Prevention/Good Housekeeping Program and the co-permittees that own and/or operate these facilities are required to implement long-term pollution prevention measures to reduce the potential for polluted stormwater runoff, including (but not limited to) the following: 1. Development of a full Stormwater Pollution Prevention Plan. 2. Development of written Standard Operating Procedures (SOPs) for activities on -site that have a significant potential to pollute stormwater. 3. Completion of required inspections. 4. Completion of required pollution prevention training for on -site staff. As of FY2021, CMSWS's inventory included a total of 3,208 properties owned by the co- permittees that have all been evaluated based on the above criteria with a total of 38 identified as having a significant potential for generating polluted stormwater runoff that have been included in the Pollution Prevention and Good Housekeeping Program as described in Tables 24, 25, 26 and 27 below. Table 24 includes a list of facilities operated by Mecklenburg County and the Towns. Five (5) private operations located on property owned by a co-permittee that have the significant potential for generating polluted stormwater runoff are also included in Table 24. These facilities are inspected once every five (5) years. Tables 25 and 26 include facilities operated by CMS and CPCC, respectively. Of the facilities and operations included in Tables 24, 25 and 26, a total of five (5) are subject to NPDES stormwater general or individual Permits 97 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services as described in Table 27. These five (5) facilities are owned and/or operated by Mecklenburg County. A more detailed explanation of the evaluation process for inclusion of facilities into the Pollution Prevention/Good Housekeeping Program is provided in Appendix D. In addition, a separate O&M Plan has been developed and is available upon request that includes the information provided in Sections 10.3, 10.4, 10.5, 10.6, 10.7, and 10.8 as well as Appendix E of this document.

Privately -operated facilities located on properties owned by a co-permittee as identified in Table 24 are responsible for conducting their own training. Training is also provided for other employees involved in municipal operations that have the potential to cause negative water quality impacts. The goal of this training seminar is to inform employees of the actions necessary to reduce the discharge of pollution and protect water quality from activities such as park and open space maintenance, fleet and building maintenance, new construction and land disturbances, storm sewer system maintenance, and other municipal activities as well as the steps for reporting suspected illicit discharges and actions required for compliance with Permit requirements. The following topics are covered in the training seminar: 1. Overview of general water quality conditions in Mecklenburg County and reasons for protecting water quality. 2. Description of common pollutants, their sources and water quality impacts associated with illicit discharges. 3. Description of the actions that each facility and/or operation should take to reduce discharges of pollutants, including good housekeeping and proper herbicide, pesticide, and fertilizer application and management. 4. Description of effective spill prevention measures that should be employed at each facility and/or operation. 5. Discussion of typical pollution sources at municipal operations and the specific action that should be taken to eliminate these sources and protect water quality. 6. Description of techniques for identifying and reporting illicit discharges and connections. This training is a Permit requirement for all municipal staff, who, as part of their normal job responsibilities, may come into contact with or otherwise observe an illicit discharge or illicit connection to the storm sewer system. 7. Description of new requirements in the Permit issued in November 2011 as follows: 100 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services • Post -construction stormwater controls for municipally owned transportation projects (see Section 9.4). • Minimizing pollution from municipally owned streets, roads, and public parking lots (see Section 10.7). • Operation and maintenance of municipally owned and maintained storm sewer system including catch basins and conveyance systems (see Section 10.8). • Management of pesticide, herbicide and fertilizer application (see Section 10.11). 8. Review of the Stormwater Pollution Prevention Plan and/or Spill Response Plan. 9. Explanation of the consequences of failing to control pollutants at facilities and/or pollutants associated with municipal operations. 10. Proper reporting of illicit discharges. The above training is conducted separately from the outreach programs conducted for the IDDE Program previously described under program element ID-5, which includes training for municipal staff, who, as part of their normal job responsibilities, may come into contact with or otherwise observe an illicit discharge or illicit connection to the storm sewer system. The training for the Pollution Prevention and Good Housekeeping Program described under program element PP-1 focuses on municipal staff involved in implementing pollution prevention and good housekeeping practices. Due to the very distinct differences in the two (2) target audiences it is necessary to separate this training. 10.5 Operation and Maintenance Programs, Spill Prevention, and Spill Response Stormwater Pollution Prevention Plans (SWPPPs) have been developed and implemented that describe the Operation and Maintenance Programs implemented at the facilities listed in Tables 24, 25, 26 and 27 above for the purpose of reducing the discharge of pollution in stormwater runoff. At a minimum, SWPPPs include the following: 1. Site Map that shows the location of the facility and all access roads. The map must also indicate the name of the receiving stream and specify if it is impaired and the source of that impairment. A USGS quadrangle map is acceptable. 2. Site Plan that shows the location of all structures on the site and the general uses of these structures (i.e., storage, vehicle maintenance, offices, etc.) as well as the locations of all stormwater inlets and outlets at or adjacent to the facility, potential pollution sources and access on and off the site. 3. Stormwater Management Plan that includes an evaluation of BMPs (if any) on the site, and descriptions of storage practices, waste handling and disposal methods and the potential on -site pollution sources including exposed significant materials. 4. Spill Prevention and Response Plan that identifies the specific actions to be taken to prevent and respond to spills, including clean up contractors and their contact information, etc. 5. Preventative Maintenance and Good Housekeeping Plan that describes the measures taken to prevent or minimize contamination of stormwater runoff from areas identified as potential pollution sources, including but not limited to areas used for vehicle and equipment cleaning. The Plan must also describe the type and frequency of site inspections and routine maintenance and the staff responsible for performing these activities. 101 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 6. Training Schedule that describes the employees that will receive training, the type of training to be provided and the schedule for that training. This training must include a discussion of all the material contained in the Stormwater Pollution Prevention Plan. All staff must be made aware of the location of this Plan at the facility. CMSWS conducts inspections of all the facilities listed in Tables 24, 25, 26 and 27 above. Facilities operated by a co-permittee are inspected annually and facilities operated by private entities on property owned by a co-permittee are inspected once every 5 years. These inspections include the following: 1. Thorough assessment of facility operations, maintenance activities, maintenance schedules and long-term inspection procedures for controls to reduce floatables and other pollutants. Pollution sources will be identified and minimized to the MEP. 2. Evaluation and documentation of the procedures for the disposal of waste removed from the MS4 and municipal operations, including street sweeping wastes, dredge spoil, accumulated sediment, floatables, and other debris, as applicable. 3. Visual evaluation of storm water outfalls at the facility and identification and minimization of pollution sources to the MEP. 4. Review of spill response and clean up procedures. Procedures will be revised as necessary to ensure protection of water quality. 5. Evaluation of housekeeping practices that will be revised as necessary to minimize potential pollution sources to the MEP. 6. Identification of all potential discharges of pollution, including parking lots, maintenance and storage yards, waste transfer stations, fleet and maintenance facilities, outdoor storage areas, salt/sand storage areas, etc. 7. Evaluation of areas used for vehicle and equipment cleaning to ensure that all discharges are to the sanitary sewer system. 8. Identification and elimination of dry weather discharges. 9. Review of Stormwater Pollution Prevention Plans annually. 10. Review of educational materials. 11. Review the timeliness of any monitoring reports required by the NPDES Permits issued to the facilities listed in Table 27 above. 12. Evaluation of the co-permittees status regarding compliance with Permit requirements, including post -construction stormwater controls for transportation projects; maintenance of municipally owned streets, roads, and public parking lots; operation and maintenance of municipally owned or maintained catch basins, conveyance systems, and structural stormwater controls; and management of pollutants from vehicle and equipment cleaning areas. In addition, CMSWS obtains the pesticide license numbers for all employees and contractors performing application activities and conducts a search on the NC Dept. of Agriculture and Consumer Services website to ensure all licenses are valid. 13. Completion of a written report documenting findings and listing actions taken to minimize pollution sources and protect water quality to the MEP. Additional inspection details are contained in the Stormwater Inspection Checklist that is reviewed and updated as necessary as part of the Phase II Work Plan developed and implemented annually by CMSWS. A copy of this checklist is provided in Appendix E. Follow up inspections are conducted as necessary to ensure the minimization of all potential pollution 102 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services sources to the MEP and documentation of corrective actions. Supervisors of facilities are contacted and provided with a copy of the written report. All reports of inspection activities are reviewed by the Water Quality Program Supervisor prior to closure. These reports are maintained in the Cityworks database. As of January 1, 2022, CMS owns and/or operates 176 schools. These schools have all been evaluated and determined not to have a significant potential for generating polluted stormwater runoff. However, the schools have the potential to generate pollutants that are not considered significant from food service areas, dumpsters without lids and plugs, erosion from high traffic areas, etc. Therefore, the schools are inspected roughly once every eight (8) years and training is provided to staff as necessary. During these inspections, pollution sources are identified and eliminated, and inspection reports completed. 10.6 Standard Operating Procedures (SOPS) for Municipal Facility Operations Written SOPs have been developed to describe the actions co-permittees are to undertake to control the discharge of pollutants from their facilities and operations to protect downstream water quality. These SOPs are provided to co-permittees and are included in their SWPPPs. CMSWS evaluates the effectiveness of the implementation of these SOPS during facility inspections as described in the previous section. 10.7 Minimizing Pollution from Municipally Owned Streets and Parking Lots CMSWS has evaluated BMPs for reducing the discharge of floatables and other pollutants from municipally owned streets and parking lots and has selected the following that are currently in use by the Phase II jurisdictions/entities (except for the Extra Territorial Jurisdiction (ETJ) areas of the Towns): • Ordinances — Each co-permittee will continue enforcement of existing litter and illicit discharge ordinances adopted by each jurisdiction. • Solid Waste Collection and Recycling — Each co-permittee will continue existing solid waste collection and recycling services. • Public Education — Each co-permittee will continue public education to encourage citizens to properly dispose of waste and to recycle as many materials as possible. • Parking Lot Cleaning — Each co-permittee will clean parking lots in identified problem areas. These problem areas are identified by staff based on accumulations of leaves, trash, debris, blockages, flooding, etc. It may also be performed after special events and festivals where additional trash and other pollutants are expected. The Town of Cornelius does the majority of its street cleaning through leaf vacuuming services that run from November 1 through January 31 each year and use their street sweeper on major thoroughfares. Each co-permittee provides trash receptacles at public parking lots and performs scheduled manual trash pick-up. Each co-permittee maintains records documenting the number of parking lots cleaned and the pounds of trash, sediment, and other pollutants removed as well as the estimated cost of the program. This data is provided to CMSWS by July 3 1 " of every year for use in evaluating program effectiveness and for inclusion in the annual report to the State. An O&M Plan has been developed for parking lot cleaning and is available upon request. 103 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Street Sweeper — Each co-permittee will sweep their municipal streets in identified problem areas. These problem areas are identified by staff based on accumulations of leaves, trash, debris, blockages, flooding, etc. Co-permittees maintain records documenting the number of streets cleaned and the pounds of trash, sediment, and other pollutants removed as well as the estimated cost of the program. This data is provided to CMSWS by July 3 1 ' of every year for use in evaluating program effectiveness and for inclusion in the annual report to the State. The County does not assume ownership or perform any maintenance activities on streets outside the jurisdictions of the Towns and City of Charlotte. For County owned parking lots, litter is picked up daily by maintenance staff, but no routine street sweeping activities are performed. An O&M Plan has been developed for street sweeping and is available upon request. Waste Disposal — Each co-permittee will be responsible for characterizing the street sweeping waste that they collect and for proper disposal of this waste based on this characterization. CMSWS will be contacted if unusual conditions are observed with the collected waste, such as the presence of oil or chemicals, unusual odors or discoloration, etc., so that testing can be performed prior to disposal. Recycling or composting is the preferred method for handling street sweeping waste. Any disposal should occur at an approved landfill. The land application of this waste onto public or private property is discouraged; however, if this does occur the application area should be a minimum of 50 feet from any stream or other water body and proper erosion control measures must be utilized to prevent off -site discharges. The above BMPs were implemented effective November 11, 2012. CMSWS performs an annual evaluation of the effectiveness of these BMPs for maintenance of municipally owned streets, roads, and public parking lots based on costs and the estimated quantity of pollutants removed. This data is presented in the annual assessment report sent to the State. CMSWS changes the BMPs as necessary based on this annual evaluation and will work with the Phase II jurisdictions/entities to ensure the timely implementation of these changes. A separate O&M Plan has been developed for maintenance of streets and parking lots and is available upon request. 10.8 Operation and Maintenance Plans for MS4s and SCMs CMSWS has evaluated BMPs for reducing the discharge of floatables and other pollutants from the municipally owned MS4, including catch basins and conveyance systems and has selected the following that are currently in use by the Phase II jurisdictions/entities: • Catch Basin and Conveyance System Cleaning — Each co-permittee will clean catch basins and conveyance systems as well as repair the MS4 in identified problem areas. These problem areas are identified by staff based on accumulations of leaves, trash, debris, blockages, flooding, etc. Each co-permittee maintains record documenting the number of inlets, outlets and pipes cleaned and the pounds of trash, sediment, and other pollutants removed as well as the estimated cost of the program. This data is provided to CMSWS by July 3 1 ' of every year for use in evaluating program effectiveness and for inclusion in the annual report to the State. • Waste Disposal — Same as for 10.7 above. 104 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services The above BMPs were implemented effective November 11, 2012. CMSWS will evaluate annually the effectiveness of the above described BMPs for maintenance of the storm sewer system based on costs and the estimated quantity of pollutants removed. CMSWS will change the SWMP as necessary based on this annual evaluation and will work with the Phase II jurisdictions/entities to ensure the timely implementation of these changes. An O&M Plan has been developed for the maintenance of MS4s and is available upon request. The co-permittees are required to implement an Operation & Maintenance Program for post - construction SCMs that it owns, including the frequency of inspections and routine maintenance requirements. All BMPs must be inspected and maintained in accordance with this schedule. The co-permittees are required to document inspections and maintenance of all municipally owned or maintained post -construction structural stormwater control measures. Section 9.4 describes how these requirements are being fulfilled. A separate O&M Plan including the above BMPs has been developed for maintenance of SCMs and is available upon request. 10.9 Evaluation of BMPs for Streets, Roads, Parking Lots, and Storm Sewer Systems The effectiveness of the BMPs identified in Sections 10.7 and 10.8 above for streets, roads, public parking lots, and storm sewer systems was evaluated in FY2022 based on cost and the estimated quantity of pollutants removed. Table 28 below summarizes the data collected as a result of this evaluation, including an estimate of the pounds of pollutants removed at 1,909,276 at a cost per pound at $0.41. Based on this data, these BMPs are determined to be highly effective and will therefore continue in use due to the significant number of pounds removed at a very low cost. This determination is based on a report produced by R.C. Sutherland, P.E. in 2013 entitled Clean Streets Mean Clean Streams that indicates an acceptable pollutant removal range is $3 to $5 per pound. Table 28: Pounds of Pollutants Removed and Costs for FY2022 BMPs Lbs. Removed Cost Cost/Lb. Street Sweeping 1,138,276 $535,964 $0.47 Parking Lot Cleaning 76,000 $26,372 $0.35 Conveyance Systems Cleaning 695,000 $223,980 $0.32 TOTALS 1,909,276 786,316 $0.41 10.10 Winter Road Maintenance The co-permittees perform maintenance activities to ensure safe winter driving conditions on its roads and parking lots. The following practices are employed by the co-permittees to reduce the discharge of pollutants from these activities. 1. Minimize the use and optimize the application of sodium chloride and other salt (while maintaining public safety) and consider opportunities for use of alternative materials. 2. Optimize sand and/or salt -brine solution rates through the use, where practicable, of automated application equipment (e.g., zero velocity spreaders), anti -icing and pre - wetting techniques and implementation of pavement management systems. 105 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan —NPDES # NCS000395 —November 2022 WATER services 3. Prevent exposure of deicing product (salt, sand, or alternative products) to precipitation by enclosing or covering storage piles. Implement good housekeeping, diversions, containment or other measures to minimize exposure resulting from adding to or removing materials from the pile. Store piles in such a manner as not to impact surface water resources, groundwater resources, and wells. 10. 11 Management of Pesticide, Herbicide and Fertilizer Application CMSWS has evaluated BMPs for ensuring that municipal employees and contractors are properly trained in pesticide, herbicide and fertilizer application as well as for ensuring compliance with all applicable permits and certifications. Based on this evaluation, the following BMPs have been selected and are currently in use by the Phase II jurisdictions/entities: • Training — Proper pesticide and fertilizer application is covered as a component of the municipal employee training described in Section 10.4. • Applicator Licenses — Each co-permittee is responsible for verifying that an employee or contractor has the proper license and/or certification for the pesticide and/or herbicide applications to be performed. Every co-permittee collects and stores copies of licenses and/or license numbers. Every year as part of the municipal inspection process described in Section 10.5, CMSWS verifies the validity of these licenses through a search of the NC Dept. of Agriculture and Consumer Services website. These licenses and certifications are updated at least annually and within 30 days of hiring a new employee or contractor. This documentation is made available in the event of an audit. Training is required for obtaining and renewing an applicator license; therefore, by verifying a license the co-permittee is also verifying that the proper training has been received. • Treatment Areas — In FY2012, an assessment was completed of each co-permittee's pesticide application and management practices. This assessment revealed that the co- permittees were in compliance with applicable NPDES requirements. Information provided by each co-permittee during this assessment revealed that their pesticide applications were below the annual treatment area thresholds contained in NCDEQ's Pesticides General Permit (NCG560000) as described in Table 29. It is the responsibility of each co-permittee to ensure continued compliance with NPDES requirements, including applying for coverage under NCG560000 if pesticide applications in the applicable treatment areas will exceed one or more of the thresholds in Table 29 during the calendar year. It is also the co-permittee's responsibility to notify CMSWS if such an application is made. During annual inspections, CMSWS will obtain a copy of annual pesticide application records. These records will be reviewed by the inspector and compared to previous years to determine if there have been significant increases in the quantities applied or areas treated in which case further investigations will be performed to determine if Permit # NCG560000 should be obtained. The application records, results of further investigations, and copies of permits issued are maintained in the facility's file.

(2) Applications that occur at the water's edge in a ditch or canal are counted only once when one or both sides are treated. (3) Applications to both sides of a road are added together for the total miles. The N.C. Pesticide Board regulates pesticide application in the Goose Creek watershed in 02 NCAC 09L .2201 through .2203. These rules apply to critical habitat areas in Goose Creek outside of the Phase II jurisdiction in Mecklenburg County. However, since critical habitat areas are prone to change, these rules will be applied in the Phase II jurisdiction/entities as one of the BMPs for this SWMP as described in Table 30. It is the responsibility of each co-permittee to ensure that the limits in Table 30 are met in the Goose Creek Watershed. CMSWS will notify the co-permittees of this requirement during annual training and inspection activities.

The above BMPs were implemented effective November 11, 2012. CMSWS continues to assess the effectiveness of these BMPs when it conducts facility inspections and receives information from the responsible party regarding compliance with the above stated provisions. CMSWS changes the BMPs as necessary and works with the Phase II jurisdictions/entities to ensure the timely implementation of these changes when inspection findings reveal a significant decline in compliance with BMP requirements. 10.12 Controlling Pollutants from Vehicle/Equipment Maintenance, Cleaning & Fueling The following procedures are followed when performing vehicle and equipment maintenance to prevent discharges to the storm drain system: 1. Vehicle maintenance should be performed indoors where contact with storm water is minimal. 2. If minor vehicle maintenance must take place outdoors, ensure that it is done during times of non -precipitation and that tarps are placed on the ground surface to collect any potential fluid spillage. 3. Any fluid spillage should be cleaned up immediately and properly disposed. Refer to the spill response procedures in the SWPPP. The following procedures are followed when performing vehicle and equipment cleaning to prevent discharges to the storm drain system. An SOP has been developed for vehicle washing and is available upon request. 1. Vehicle washing areas should drain to a permitted sanitary sewer system, if available. 2. If no sanitary sewer connection is available, the facility should either wash vehicles at a car wash facility or designate an on -site vehicle washing area that is not directly connected to a storm drain system, such as grassed areas, gravel parking areas, or a water quality BMP. This washing area must be designated on the Site Plan Map in the SWPPP. The following restrictions apply to these designated washing areas not connected to the sanitary sewer system: • Only biodegradable detergents can be used with a pH between 4.0 and 9.0. • Solvents cannot be used to clean vehicles in this area. • Only vehicle exteriors should be washed. Engines or oily equipment / parts cannot be washed in these areas. • Water usage should be minimized to the extent practicable by using a pressure washer or low flow nozzle. The following procedures are followed when performing vehicle and equipment fueling to prevent discharges to the storm drain system: 1. Employees are to remain with vehicles and equipment during fueling operations. 2. Vehicles should not be "topped off." 3. Spill kit materials should be available in the immediate vicinity of the fueling area in the event of a spill. il: Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 4. Any spilled fuel should be cleaned up immediately and properly disposed. Refer to the spill response procedures in the SWPPP. 10.13 Waste Disposal During the inspections described in Section 10.5 above, CMSWS evaluates methods for disposing of waste removed from each jurisdiction's MS4 and municipal operations, including dredging spoil, accumulated sediments, cooking oils, trash, wash water, and debris. Actions are taken as necessary to minimize pollution sources associated with these waste storage and disposal measures by working closely with the facility supervisor and/or public works director. 10.14 Flood Management Projects CMSWS designs and constructs flood management and stream restoration projects in the Mecklenburg County Phase II jurisdictions as well as the City of Charlotte. Where practicable, CMSWS incorporates structural BMPs into these projects to reduce pollutant loads and improve aquatic habitat. In some cases, chemical, physical and/or biological monitoring is performed upstream, downstream and within the boundaries of the project. This monitoring usually begins prior to the initiation of construction activities and continues throughout the duration of the project and for a minimum of one year following project completion. Data generated from these monitoring activities is evaluated to identify those techniques that are most effective at restoring water quality for use in future projects. Figure 13 illustrates one such project in the Hidden Valley community in Charlotte where wet ponds, wetlands and stream meanders were incorporated into a flood management project for enhancement of water quality. Figure 13: Stream Restoration in the Torrence Creek Watershed in Huntersville 10.15 Decision Process The individual BMPs for the Pollution Prevention/Good Housekeeping Program were selected because they have proven effective when used by the City of Charlotte for compliance with their Phase I Permit requirements. Staff was selected for implementation of the BMPs for the 109 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Pollution Prevention/Good Housekeeping Program based on their knowledge of proper facility operation and pollution prevention. 10.16 Program Evaluation The measurable goals for each BMP are described in Table 23. The overall success of the Pollution Prevention and Good Housekeeping Program is evaluated through the successful achievement of these measurable goals as reported with each NPDES MS4 annual assessment report. At a minimum, the following metrics are included in this annual report: • Number of employees trained. • Number of streets and parking lots cleaned, and amount of material removed. • Number of inlets, outlets and pipes cleaned, and amount of material removed. • Description of educational activities completed. Other measures of success for the Pollution Prevention and Good Housekeeping Program are described below. • Documentation of Stormwater Program Activities: As a baseline measure of success, staff will document completion of Work Plan program activities annually that demonstrate successful fulfillment of BMPs associated with this program element. All activities will be documented within CMSWS's Cityworks database. • Improving Compliance: CMSWS will track the ratio of the number of deficiencies observed at municipal facilities to the number of inspections conducted with a decrease from the previous fiscal year serving as an indicator of success at improving compliance at Phase II municipal facilities. On an annual basis, CMSWS staff will evaluate the BMPs assigned to this program and assess progress toward achieving the measurable goals from Table 23 and the measures of success described above. Recommendations for improvement will be made as necessary. During the following fiscal year, the program activities and BMPs will be modified as necessary based on the results of this evaluation in order to ensure that the specific goals and objectives of the Pollution Prevention and Good Housekeeping Program and SWMP are being effectively and efficiently fulfilled. The evaluation will include an assessment of the effectiveness of BMPs in use to reduce pollutants from municipally owned streets, roads, parking lots, catch basins, and stormwater conveyance systems. This evaluation will be based on data received from the co- permittees regarding costs and the estimated quantity of pollutants removed. CMSWS will change the SWMP as necessary based on this annual evaluation and will work with the Phase II jurisdictions/entities to ensure the timely implementation of these changes. 110 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER rl� services SECTION 11: TMDL WATER QUALITY RECOVERY PROGRAM A Water Quality Recovery Program has been developed and is currently being implemented for addressing nonpoint source pollutant loadings associated with the Total Maximum Daily Loads (TMDLs) approved by EPA for the receiving waters of the Phase II MS4 stormwater discharges and/or waters downstream of these discharges. Section 3.5 of this document describes the TMDLs applicable to Mecklenburg County Phase II jurisdictions and entities. The Program is administered by CMSWS's Water Quality Program as described in the following Sections. The purpose of this Program is to facilitate the implementation of activities within the scope of the Phase II Permit's six (6) minimum measures to reduce the assigned Waste Load Allocations (WLAs) for the stormwater pollutant of concern to the maximum extent practicable (MEP). This Program is intended to meet the TMDL requirements of MS4 Permit number NCS000395. 11.1 Program Goals and Objectives CMSWS establishes its goals and objectives for its TMDL Program, which are evaluated and updated annually as necessary, based on the actions necessary to effectively address the pollutant(s) of concern in the applicable TMDL and to address the targeted pollutants and pollutant sources identified in Table 9. The goal of the TMDL Program is to reduce levels of the pollutant(s) of concern to the MEP in accordance with approved WLAs assigned to stormwater in the approved TMDL. The current objectives of the program are as follows: 1. Develop and implement appropriate structural and/or non-structural BMPs to reduce nonpoint source loading for the pollutant(s) of concern to the MEP in the TMDL watersheds. 2. Assess the effectiveness of existing BMPs and identify and implement additional measures as necessary to address impaired waters. Incorporate additional measures into the SWMP and annual Work Plan for implementation. 3. Submit a report to NCDEQ annually describing activities completed in the implementation of existing BMPs as well as the results of the annual assessment and additional BMPs that have been identified for implementation, including a brief explanation as to how the BMPs will address impaired waters. Part II, Section H of Mecklenburg County's Phase II Permit requires compliance with TMDLs applicable to the receiving waters for MS4 discharges from the Phase II jurisdictions and/or waters downstream of these discharges. To comply with this requirement, CMSWS evaluates the current 305(b) report and 303(d) list for N.C. at least annually and identifies those impaired waters with an approved TMDL applicable to Mecklenburg County's Phase II jurisdictions. For these applicable TMDLs, CMSWS develops and implements strategies and tailored BMPs to reduce nonpoint source loading for the pollutants of concern to the MEP. These strategies and BMPs are evaluated annually for effectiveness and modified as necessary. While improved water quality is the expected outcome, the Phase II Permit obligation is to reduce nonpoint source pollutant loading to the MEP. The Phase II jurisdictions are not responsible for attaining water quality standards at the ambient monitoring stations. Attaining the water quality standards will only be achieved through reduction from the MS4, along with reductions from other pollutant contributors.

The pollutants of concern for those TMDLs where the City of Charlotte is assigned as the lead in Table 3 are described in their NPDES MS4 TMDL Watershed Plan, which is available through their Phase I contact. 11.3.1 Fecal Coliform TMDLs Fecal coliform bacteria are present in the intestines of humans as well as warm- and cold- blooded animals. Fecal coliform themselves are usually harmless but serve as indicators of the presence of pathogenic bacteria. Fecal coliform in surface waters can originate from many point and nonpoint sources, including but not limited to wildlife, pet waste, failing septic systems, cross connections resulting in dry weather flow in stormwater outfalls, sanitary sewer overflows (SSOs), sewer exfiltration, and permitted discharges such as wastewater treatment plants (WWTPs). The control of fecal coliform is necessary for protection of human health. The NC in -stream standard for fecal coliform is a 30-day geometric mean of 200 colonies/100 ml or a daily maximum value of 400 colonies/100 mL (15A NCAC 2B .0211 (3)(e)). Due to a greater than 10% exceedance of the 400 colonies/100 ml standard, a fecal coliform TMDL was developed and subsequently approved for the Rocky River effective September 19, 2002 and for Goose Creek effective July 8, 2005. The TMDL for the Rocky River established reductions in fecal coliform load allocations for nonpoint sources in wet weather conditions as follows: high density development at 91%, low density development at 91%, livestock grazing at 86%, and manure application at 80%. Reductions in load allocations for nonpoint sources in dry weather 113 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services conditions are as follows: high density development at 33%, low density development at 33%, livestock grazing at 30%, and manure application at 30%. The TMDL for Goose Creek established reductions in fecal coliform load allocations for nonpoint sources at 92.5%. 11.3.2 Nutrient TMDL High concentrations of nitrogen and phosphorus in surface waters can degrade aquatic environments, resulting in excessive algal growth, decreased dissolved oxygen concentrations, and stressed aquatic biota. Elevated nutrient levels are often associated with point and nonpoint pollution sources, including but not limited to agriculture, urban runoff, and permitted discharges such as WWTPs. The monitoring and control of nutrients is therefore necessary to limit algal growth that can degrade water quality. Chlorophyll -a concentration is currently utilized as a proxy parameter for monitoring nutrient levels in surface waters, as water quality standards have not been established for nitrogen and phosphorus. NCDEQ regulates nutrient concentrations through a Chlorophyll -a standard of 40 ug/l. In a 1992 Report by NCDEQ and the S.C. Department of Health and Environmental Control (Report # 92-04), eutrophic conditions were documented in Lake Wylie and several of its major tributaries. In response, NC developed a point and nonpoint source nutrient control strategy for the Lake Wylie Watershed. For point sources, the strategy required state-of-the-art nutrient removal for all new or expanded wastewater discharges in the vicinity of the lake. In addition, existing facilities on tributaries to the three (3) most highly eutrophic arms of the lake, including the South Fork, Catawba Creek and Crowders Creek, were required to meet stringent nutrient removal requirements. For nonpoint sources, the strategy included the targeting of funds from the State's Agricultural Cost Share Program for the reduction of nonpoint source pollution for implementation of BMPs on agricultural lands to highly impacted watersheds on Lake Wylie. The strategy subsequently was approved for implementation as a TMDL by EPA effective February 5, 1996. The TMDL does not include a WLA assigned to stormwater. 11.3.3 Mercury TMDL In 2012, NCDEQ developed a statewide mercury TMDL to determine how wastewater discharges, including in -state and out-of-state air sources, contribute to the surface water mercury loading. This TMDL acknowledged that most mercury in stormwater comes from atmospheric deposition and that concentrations are typically within the same range as mercury concentrations in rainwater, which is between zero and 10 ug/l. This TMDL does not include a WLA assigned to stormwater; therefore, there is not an NPDES MS4 Permit obligation to reduce non -point source pollutant loading. For this reason, TMDL compliance measures for this TMDL are not included in this SWMP. 11.4 Watershed Characteristics The following sub -sections describe the characteristics for those TMDL watershed where Mecklenburg County is assigned as the lead in Table 3, including portions of the Rocky River, Lake Wylie and Goose Creek. The watershed characteristics for those TMDLs where the City of 114 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan —NPDES # NCS000395 —November 2022 WATER services Charlotte is assigned as the lead in Table 3 are described in their NPDES MS4 TMDL Watershed Plan, which is available through their Phase I contact. 11.4.1 Rocky River Watershed The Rocky River Watershed (Assessment Unit 13-17a) is located in the Yadkin/Pee Dee River Basin in the northeast corner of Mecklenburg County and extends into portions of Iredell and Cabarrus Counties.

The following staff positions with CMSWS were identified as key members of the TMDL team: • County Environmental Manager • County Environmental Supervisor • County Environmental Analyst • County Environmental Specialist I, II, III • City Environmental Manager • City Water Quality NPDES Supervisor • City Water Quality NPDES Administrator • City Land Development Erosion Control Administrator • City Water Quality Public Information Specialist • City Water Quality Modeler • City Water Quality Planner • City Water Quality Senior Specialist • City Water Quality Post -Construction Administrator • City Stormwater MS4 Inventory Supervisor • City Utility Department Sanitary Sewer System Administrator 11.7 MS4 Major Stormwater Outfalls in the TMDL Watersheds The major stormwater outfalls in the TMDL watersheds where Mecklenburg County is the lead, including portions of the Rocky River, Goose Creek and Lake Wylie, have been identified through MS4 inventory collection activities and are illustrated in Figures 15, 18 and 21, respectively. The number of outfalls recorded in each watershed is shown in Table 35. These outfalls are available in a GIS layer in CMSWS's Cityworks database along with stormwater inlets. The schedule to discover additional major outfalls is described in Section 7.4 of this document. The major stormwater outfalls in the TMDL watersheds where the City of Charlotte is the lead are described in their NPDES MS4 TMDL Watershed Plan, which is available through their Phase I contact. 128 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services Table 35: Number of Outfalls in each TMDL Watershed Watershed Number of Outfalls Rocky River 4 Goose Creek 183 Lake Wylie 233 Total 420 11.8 Existing BMP Measures As discussed in Section 11.3, the primary pollutants of concern for the TMDL watersheds where Mecklenburg County is the lead are fecal coliform bacteria, chlorophyll -a and mercury. Since the Statewide mercury TMDL does not have a WLA assigned to stormwater there is not an NPDES MS4 Permit obligation to reduce non -point source pollutant loading. For this reason, TMDL compliance measures for this TMDL are not included in this SWMP. For fecal coliform bacteria and chlorophyll -a, CMSWS has reviewed existing strategies and BMPs within the scope of the six (6) minimum Phase II Permit compliance measures and has identified those BMPs identified in the following subsections as suitable for best addressing those waters impaired due to these pollutants of concern. All the strategies and BMPs described below are currently being implemented in the Phase I and Phase II jurisdictions in Mecklenburg County. 11.8.1 Public Education & Outreach The following existing public education and outreach activities have been identified as suitable for addressing the pollutants of concern in the TMDL watersheds. These BMPs will address impaired waters by informing the community of the impacts of the pollutants of concern on water bodies and the steps that the public can take to reduce these pollutants.

Flood Management Projects (see Section 10.14) 11.9 Water Quality Monitoring and Data Assessment CMSWS conducts fixed interval stream monitoring (see Section 7.7.1.2) at identified locations in or immediately downstream of the TMDL watersheds on a monthly basis as indicated in Figures 15, 18 and 21. This monitoring is primarily used to determine water quality trends, and to detect pollution problems in surface waters. Monitoring results that exceed threshold values are referred for follow-up under the IDDE program. CMSWS also conducts routine lake monitoring every other month during the calendar year as follows: January, March, May, July, September, and November. Monitoring for fecal coliform bacteria is performed monthly during the summer months from May through September. Data from this lake monitoring is used to identify trends and to initiate watershed management strategies for restoring degraded water quality conditions. CMSWS also maintains a Continuous Monitoring and Alert Notification Network or CMANN that monitors surface waters at select sites in streams and lakes for turbidity, dissolved oxygen, temperature, conductivity, and pH. All monitoring results that exceed threshold values are referred for follow-up under the IDDE program. 11.9.1 Fecal Coliform Monitoring and Data Assessment for the Rocky River As identified in Table 3, a section of the Rocky River in Mecklenburg County (AU Number 13- 17a) is subject to a fecal coliform TMDL with a WLA assigned to stormwater that was approved on September 19, 2002. Mecklenburg County has been assigned responsibility for compliance with this TMDL on behalf of the Phase I and Phase II jurisdictions in Charlotte -Mecklenburg. Phase II Permit conditions required that a monitoring plan be developed for the Fecal Coliform TMDL in the Rocky River Watershed unless a waiver was obtained from NCDEQ. Such a waiver was obtained on June 26, 2014, based on the condition that Mecklenburg County 132 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan - NPDES # NCS000395 -November 2022 WATER services continue to evaluate the land use and development within the watershed on an annual basis and if additional stormwater infrastructure is installed or higher intensity land uses are constructed a Monitoring Plan would be reconsidered. In response to this condition, CMSWS has obtained impervious area and landuse data from the County GIS Department back to 2011 and continues to update this data annually (see Table 36). To date, changes in the watershed are not significant enough to warrant the establishment of a Monitoring Plan. Table 36: Annual Anal sis of the Rocky River Watershed for the Monitoring Plan Year Residential Impervious Cover (acres) Commercial Impervious Cover (acres) Total Impervious Cover (acres) Storm Water Outfalls (number) 2011 14.22 0.33 14.55 1 2012 14.22 0.33 14.55 1 2013 14.55 0.33 14.88 3 2014 14.88 0.33 15.21 3 2015 15 0.33 15.33 4 2016 15.1 0.33 15.43 4 2017 15.2 0.33 15.53 4 2018 15.69 0.33 16.02 4 2019 15.72 0.33 16.05 4 2020 15.72 0.33 16.05 4 2021 16.03 0.33 16.36 4 # Increase from 2011 1.81 0.00 1.81 3 % Increase from 2011 12.73% 0.00% 12.44% 300% Although CMSWS does not perform monitoring in the Rocky River TMDL watershed, it obtains monthly monitoring data collected by the NCDEQ, Division of Water Quality at Q7330000, which is the specific monitoring location for this TMDL. CMSWS completed an analysis of the fecal coliform data collected by the State in calendar year 2021, which is the most current data available. The geometric mean concentration of these samples was 491.22 CFU/100 ml. This represents an approximate 13.6% increase from the geometric mean concentration observed in calendar year 2020 at 432.40 CFU/100 ml. Out of the 12 samples collected in 2021, seven (58%) exhibited concentrations below 400 CFU/100 ml. The remaining five samples (42%) exceeded the 400 CFU/100 ml threshold. The North Carolina Administrative Code (NCAC) 02B Fresh Surface Water Quality Standards dictate that fecal coliform "shall not exceed a geometric mean of 200 [CFU]/100 ml... nor exceed 400 [CFU]/100 ml in more than 20 percent of the samples examined...". 11.9.2 Fecal Coliform Monitoring and Data Assessment for Goose Creek As identified in Table 3, two (2) sections of Goose Creek in Mecklenburg County (AU Numbers 13-17-18a and 13-17-18b) are subject to a fecal coliform TMDL with a WLA assigned to stormwater that was approved on July 8, 2005. According to the approved NC 2018 305(b) report, the two (2) TMDL segments of Goose Creek are currently meeting the fecal coliform 133 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan —NPDES # NCS000395 —November 2022 WATER services criteria. Mecklenburg County has been assigned responsibility for compliance with this TMDL on behalf of the Phase I and Phase II jurisdictions in Charlotte -Mecklenburg. CMSWS maintains a fixed interval monitoring site (MY9) at Stevens Mill Road where it crosses Goose Creek in Union County. During FY2020, eight (8) of the 15 samples collected (53%) exhibited concentrations at or below 400 CFU/100 ml. No pollution sources were identified as a result of the water quality monitoring in the Goose Creek TMDL watershed in FY2020. 11.9.3 Chlorophyll -A Monitoring and Data Assessment for Lake Wylie As identified in Table 3, two (2) sections of Lake Wylie in Mecklenburg County (AU Numbers 11-122 and 11-(I23.5)a) are subject to a chlorophyll -a TMDL approved on February 5, 1996 that does not include a WLA assigned to stormwater. Mecklenburg County has been assigned responsibility for compliance with this TMDL on behalf of the Phase I and Phase II jurisdictions in Charlotte -Mecklenburg. Surface Water Quality Standards have not been established for nitrogen and phosphorus. As a result, CMSWS utilizes Chlorophyll -a concentration as a proxy parameter for monitoring nutrient levels in Lake Wylie. According to the approved NC 2018 305(b) report, the two TMDL segments of Lake Wylie are currently meeting the Chlorophyll -a criterion of 40 micrograms per liter (µg/L). All 44 Chlorophyll -a samples collected by CMSWS in Lake Wylie in 2020 were below 40 µg/1. 11.9.4 Mercury Monitoring and Data Assessment Statewide As stated in sub -section 11.3.3, the State did not include an MS4 NPDES WLA for mercury in their statewide TMDL; therefore, an analysis of mercury data is not included in this document. 11.9.5 Effectiveness of BMPs Based on Data Analysis Every year in an annual report, CMSWS will report on the effectiveness of BMPs based on an analysis of available water quality data. Based on data collected through the end of calendar year 2021, a general improvement in water quality is identified; therefore, it is determined that the current BMPs are effective at identifying and eliminating pollution sources in compliance with TMDL requirements and that these BMPs will continue to be implemented in FY2022. Additional structural and/or non-structural BMPs will be implemented as described in Section 11.10 to further enhance TMDL compliance. 11.10 Additional BMP Measures Implemented through FY2022 Over the past several years CMSWS has developed and implemented numerous BMP measures in addition to those described in Section 11.8 in order to improve water quality conditions in the TMDL watersheds by identifying and eliminating sources of the pollutant of concern. These historic additional measures along with new measures proposed beginning in FY2022 are described in the following subsections by TMDL watershed. 11.10.1 Additional BMP Measures in the Rocky River Watershed During the fiscal years (FY) indicated below (July 1 through June 30), the following actions 134 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services were completed to reduce fecal coliform bacteria levels and enhance water quality in the Rocky River Watershed. FY2015 1. In November 2014, approximately 250 trees were planted in the buffer at the Rocky River Bluff Nature Preserve (Parcel Number 00307115) by a total of 31 volunteers through a partnership between CMSWS, Mecklenburg County Park & Recreation Department, and the Davidson Lands Conservancy. Partial funding for the event was provided through an Urban Cost Share Grant. This enhanced buffer will provide additional filtering for nonpoint source pollutants that will assist with TMDL pollutant removal. 2. CMSWS completed a review of historic aerial imagery from the Rocky River Watershed, which revealed that since 1993 an equestrian area had been located approximately one- half mile upstream of monitoring site Q733 on the Mecklenburg County side of the Rocky River. In recent years, a septic system was installed to treat wash water from a stable located in this area. CMSWS performed monitoring upstream and downstream of this potential source. Results indicate that the septic system was not a source of fecal coliform bacteria. FY2016 1. High resolution aerial imagery was evaluated, and no sources of fecal coliform bacteria were identified. 2. Agricultural operations in the watershed, which are mainly horse farms, were evaluated and no sources of fecal coliform bacteria were identified. 3. Health Department records were reviewed and only two (2) failed septic systems were identified in the watershed between FY2009 and FY2016, which suggest that failing septic systems are not a chronic problem in this area. Inspections were conducted where these failing systems had been detected and no sources of fecal coliform bacteria were identified. 4. The four (4) outfalls in the watershed were inspected and no evidence of dry weather flows was observed. These inspections were documented in GIS using the ESRI app for iPhone. 5. The Mecklenburg County Soil & Water Conservation District worked with the property owner at 18005 Callaway Hills Lane in Davidson, N.C. to complete a stream bank stabilization project immediately upstream of the first stormwater outfall shown in Figure 15. The cost of the project was $42,000 with the NC Ag Cost Share Program reimburse the landowner $32,000, leaving the landowner portion at $10,000. The completion of this project will reduce the sediment load in the stream, which will in -turn reduce fecal coliform bacteria levels. FY2017 1. The four (4) outfalls in the watershed were inspected and no evidence of dry weather flows was observed. These inspections were documented in Cityworks. 2. On June 27, 2017, fecal coliform samples were collected from the Rocky River where it enters and exits Mecklenburg County. Results indicated fecal coliform levels at 980 and 1020 colonies/100ml, respectively. This represents an insignificant increase. 135 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 3.

No pollution sources were detected. FY2020 1. Routine fixed interval monitoring was conducted monthly at sites MY-9 (Goose Creek — Stevens Mill Road) and MY-14 (Duck Creek — Tara Oaks Lane). Monthly samples were 139 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER �—� S.MceS analyzed for 16 parameters including fecal coliform and E. coli. Monitoring results are described in Section 11.9.2. 2. Beginning on November 1, 2019 and concluding on April 28, 2020, CMSWS staff walked approximately 60.97 stream miles in the Phase II jurisdictions, including 21.57 in the Towns and 39.4 miles in the ETJ areas located in the County. In all, 34 points or features, 18 outfalls inspected, 13 new outfalls, and two dry weather flow samples were collected. No exceedances above the fecal coliform action level (>3000 col/100ml) were identified. One sample exhibited a total phosphorus level in exceedance of the action level of 0.50 ppm. Three significant problems and 15 stream blockages were identified and reported to Mecklenburg County Storm Water Operations. No illicit discharges of pollution sources were observed during 2020 Phase II stream walk activities. 3. On January 3, 2020, Health Department records were reviewed, and no failed septic systems were identified. 2021 1. Routine fixed interval monitoring was conducted monthly at site MY9 (Goose Creek — Stevens Mill Road) for 16 parameters including fecal coliform and E. coli. Monitoring results are described in Section 11.9.2. 2. Beginning on November 1, 2020 and concluding on April 20, 2021, CMSWS staff walked approximately 74.84 stream miles in the Phase II jurisdictions (see Figure 2). In all, 69 points or features were collected, 77 outfalls were inspected, and 52 new outfalls were recorded. Ten dry weather flows were observed but all were too low to sample. Six significant problems and two stream blockages were also identified and reported to Mecklenburg County Storm Water Operations. No illicit discharges of pollution sources were observed during 2021 Phase II stream walk activities. 3. On January 8, 2021, Health Department records were reviewed, and no failed septic systems were identified. 2022 1. Routine fixed interval monitoring was conducted monthly at site MY9 (Goose Creek — Stevens Mill Road) for 16 parameters including fecal coliform and E. coli. Monitoring results are described in Section 11.9.2. 2. Beginning on November 1, 2021 and concluding on April 22, 2022, CMSWS staff walked approximately 127.7 stream miles in the Phase II jurisdictions (see Figure 2). In all, 179 points or features were collected, 68 existing outfalls were inspected, and 65 new outfalls were recorded. Five dry weather flows were observed but all were too low to sample. Three significant problems and 11 stream blockages were also identified and reported to Mecklenburg County Storm Water Operations. Additionally, one illicit discharge was observed which resulted in the issuance of a Notice of Violation. 3. On October 7, 2021, Health Department records were reviewed, and no failed septic systems were identified. 4. Throughout FY2022, in -stream fecal coliform and E. coli samples were collected in headwater areas of the of Goose Creek watershed to identify potential illicit discharges and sources of fecal coliform. Sampling was performed during ambient (not storm impacted) conditions and locations were selected based on proximity to low-pressure sanitary systems and historical analytical data. A total of 37 samples were collected from 140 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER ��, Services 23 locations within upper Goose Creek and associated tributaries. Twenty-five of the samples exceeded 400 CFU/100 mL and the geometric mean of all samples was 794.52 CFU/100 ml. Additional evaluations were performed in locations where the highest fecal coliform and E. coli concentrations were observed. These evaluations included follow-up sampling, camera inspections of private sanitary laterals, and inspection of livestock farms for manure releases. No damaged infrastructure or discharges were observed. 11.10.3 Additional BMP Measures in the Lake Wylie Watershed During the fiscal years (FY) indicated below (July 1 through June 30), the following actions were completed to reduce fecal coliform bacteria levels and enhance water quality in the Lake Wylie Watershed: FY2009 a. On March 23, 2009, high levels of Chlorophyll -a were observed in Wither's Cove that exceeded the State standard. In response, CMSWS completed a full assessment of the cove and watershed, including a windshield survey to identify potential pollution sources. The Siemens facility that discharges directly to the cove was inspected and sampled. Elevated copper levels were detected in the intake filter backwash from the facility. Consultation with NCDEQ revealed that annual sampling was required of the backwash but there were no Permit limits. On April 8, 2009, additional sampling was performed at 10 sites in the cove and tributaries draining to the cove. No nutrient sources were detected. All Chlorophyll -a levels had returned to normal. The March 2009 event appears to have been an algae bloom. During FY2020, FY2021 and FY2022, physical assessments (Stream Walks) are planned for all the tributaries draining into Lake Wylie in Mecklenburg County, including all of Long Creek and Paw creek. These assessments will include, stormwater outfall inventory and inspection, bacteria sampling both instream and any dry weather flows, as well as visual inspection for sources of fecal coliform bacteria. 11.10.4 Additional BMP Measures Planned for TMDL Watersheds in FY2023 As discussed in Section 11.9.5, existing BMPs were found to be effective and will therefore continue to be implemented in FY2023. Additional BMPs to be implemented and associated schedules for FY2023 are provided below. 1. Routine monitoring will continue to be performed monthly by CMSWS at MY9 on Goose Creek at Stevens Mill Road and by NCDEQ, Division of Water Quality at site Q7330000 on Rocky River at SR 2420. Exceedances of established water quality watch and action levels will be identified and follow up actions conducted as necessary for the identification and elimination of pollution sources. 2. By December 30, 2022, CMSWS will complete a review of Health Department records to determine where failed septic systems have been identified in both the Rocky River and Goose Creek TMDL watersheds. Follow up inspections and monitoring will be performed as necessary to ensure the elimination of sources of fecal coliform bacteria associated with failed septic systems thereby addressing impaired waters. 141 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services 3. By March 31, 2023, major outfalls will be inspected in the Rocky River TMDL watershed. Dry weather flows will be identified, and pollution sources eliminated thereby addressing impaired waters. 4. Construction activities associated with the restoration of an additional 5,000-foot section of West Branch Rocky River are expected to begin in late FY2023 or early FY2024. Historically, West Branch Rocky River has been severely degraded by storm water flows that erode the stream banks. The restoration project will stabilize the stream banks to reduce erosion and improve water quality. 5. Targeted surface water sampling in headwater areas of the Goose Creek watershed will continue in FY2023. Based on the results of FY2022 activities, additional surface water quality and watershed data is needed to further delineate sources of fecal coliform to the system. Watershed modeling and septic system assessments will be utilized to inform decision making and identify potential problem areas. 11.11 Tracking and Reporting Success The overall success of the TMDL Program is evaluated through the successful achievement of these measurable goals as reported with each NPDES MS4 annual assessment report. At a minimum, the following metrics are included in this annual report: • Number of BMP compliance activities completed by TMDL watershed; • Effectiveness of BMPs based on an assessment of applicable monitoring data; and • Future BMPs to be implemented to improve water quality and satisfy TMDL requirements. CMSWS will document all activities completed for the identification and elimination of pollution sources in the TMDL watersheds, including all inspections conducted and corrective actions implemented. All confirmed pollution sources will be mapped in GIS and where possible pollutant loads will be estimated. This data will be tracked over time as a measure of the success of program activities. 11.12 Reporting CMSWS will prepare an annual report for activities relating to the implementation of the water quality restoration activities for the TMDL watersheds where Mecklenburg County has been assigned responsibility, including Rocky River, Goose Creek and Lake Wylie. The report will be submitted to NCDEQ by October 1 of each calendar year. The report will at a minimum include the following information: 1. Description of water quality restoration activities completed during the past fiscal year. 2. Description of water quality restoration activities expected to occur next fiscal year. 142 ' Charlotte Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER Services Appendix A: BMP Summary Table 143 Charlotte -Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 WATER services A B C D E County Activities BMP County Work No. Plan Code Description of Schedule for Annual Co-Permittee BMP Measurable Goal(s) Implementation Reporting Responsibilities Metric Permit Development (Permit Ref.

Specifically, this policy is written for public transportation projects that involve roadway construction not associated with a subdivision or development. Please note that this policy document does not apply to: Roadway projects associated with development — These projects (such as road widening or turn lane addition) are treated as part of the development and the right-of-way area and built - upon area should be included in stormwater calculations for the development. Roadway projects constructed by the North Carolina Department of Transportation (NCDOT) - These projects are subject to NCDOT's Post -Construction program; therefore, these projects are not subject to local Post -Construction ordinances. The North Carolina Division of Water Quality (NCNCDEQ) suggests that regulated public entities use BMPs in the North Carolina Department of Transportation's (NCDOT's) "Best Management Practices Toolbox" developed for linear systems, which has been approved by NCDEQ to meet post - construction requirements for linear roadway systems. Applicability Public roadway projects are subject to the applicability criteria of the applicable jurisdiction's Post - Construction ordinance in which the project is located. For post -construction purposes, public roadway projects will be considered commercial/industrial development or redevelopment. The post - construction applicability criteria are found in Section 105 of the Post -Construction ordinances for all Phase II jurisdictions with the exception of the Town of Huntersville, where the applicability criteria are contained within Section 8.17.3 of the ordinance and the Town of Matthews where the applicability criteria are found in Section 154.005. The grandfathering (or exemption) of public projects is consistent with the rights given to private developers under applicability and exceptions provisions of the Post -Construction ordinances. In the event that Post -Construction ordinance requirements apply to a public roadway project, the responsible public entity shall work with the staff of Charlotte Mecklenburg Stormwater Services' Water Quality Program to ensure compliance. BMPs for Public Linear Roadway Projects The North Carolina Department of Transportation (NCDOT) developed a list of structural BMPs suitable for linear projects published in NCDOT's Stormwater Best Management Practices Toolbox. NCDOT's BMP Toolbox has been approved for use by NCNCDEQ for linear roadway projects. To the extent practicable, the jurisdictions shall use BMPs from the North Carolina Department of Transportation's "Best Management Practices Toolbox" developed for linear systems, which has been approved by NCNCDEQ to meet post -construction requirements for linear roadway systems. The designs in the Charlotte -Mecklenburg BMP Design Manual are also used where practicable. In addition, when public linear roadway projects use bridges over surface waters, bridge drainage systems that eliminate or minimize direct discharge to surface waters are required. More information on bridge drainage systems can be found in Chapter 9 of NCDOT's BMP Toolbox. A copy of 173 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER N� services NCDOT's BMP Toolbox can be found at the following website: https:Hconnect.ncdot.gov/resources/hydro/HSPDocuments/2014_BMP_Toolbox.pdf BMP Maintenance Perpetual maintenance is required on all public -owned BMPs by the jurisdiction constructing the roadway. Each BMP shall be recorded in the Charlotte -Mecklenburg Stormwater Services — County Water Quality Program BMP database and will be subject to annual compliance inspections and periodic maintenance. The only exception to this is when roadway projects are constructed to NCDOT standards that are to be turned over for maintenance to NCDOT following construction. These BMPs shall be maintained in accordance with NCDOT requirements and shall not be subject to the local post -construction ordinance maintenance requirements. 174 ' Charlotte Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER Services Appendix D: Phase II Municipal Facility Inventory Procedures 175 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services Phase II Municipal Facility Inventory Standard Operating Procedures (SOPs) (PP-5) September 2020 Purpose The purpose of this document is to describe how Charlotte -Mecklenburg Storm Water Services (CMSWS) will fulfill Section G.2.a. of Permit NCS000395 in that requires the development of an inventory of all the Phase II municipal facilities and operations owned and/or operated by the County, Towns, CPCC and CMS that have significant potential for generating polluted stormwater runoff. This document further describes what actions will be taken by CMSWS to address this pollution potential in compliance with Permit requirements. This is under the section of the Permit entitled Pollution Prevention and Good Housekeeping for Municipal Operations. Procedure for Evaluation of Facilities During the first Permit term, the following language was contained in Section G regarding Pollution Prevention and Good Housekeeping for Municipal Operations: "Develop an inventory of all facilities and operations owned and operated by the permittee with the potential for generating polluted stormwater runoff. Specifically inspect the potential sources of polluted runoff, the stormwater controls, and conveyance systems. Evaluate the sources, document deficiencies, plan corrective actions, and document the accomplishment of corrective actions." CMSWS updated its Stormwater Quality Management Program Plan (SWMP) effective July 1, 2005 to include procedures to evaluate 20 percent of the municipal operations each year of the 5- year Permit ending June 30, 2010 in order to identify the facilities and operations owned and/or operated by the County, Towns, CPCC and CMS that have significant potential for generating polluted stormwater runoff and are therefore required to comply with this part of the Permit. The program element for this requirement was PP-5. CMSWS used the phased approach described in "A" below to conduct this evaluation. This evaluation was completed by the end of the Permit term on June 30, 2010, resulting in the development of the Tables 24, 25, 26 and 27 of the FY2022 version of the SWMP. Mecklenburg County's Phase II Permit was renewed on November 11, 2011. This new Permit changed Section G from applying to facilities with the "potential for generating polluted stormwater runoff' to applying to facilities with the "significant potential for generating polluted stormwater runoff." This change resulted in CMSWS changing its evaluation procedures to those described in `B" below. This evaluation was completed at the end of the Permit term on June 30, 2015. A. FIRST PERMIT TERM 1. Accumulate a listing of all county and town -owned properties in a spreadsheet format. 176 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services 2. Determine if the properties are located in an urbanizing area (UA). All properties in Mecklenburg County have been deemed to be an urbanizingarea rea by the State of North Carolina. 3. Determine which properties do not contain building improvements (i.e., vacant parcels). Properties containing no building improvements are deemed to have no potential to pollute stormwater and will not likely have a stormwater conveyance system. To conduct this evaluation, CMSWS will: a. Use the attached spreadsheet format to collect data from each jurisdiction including the County (spreadsheet already completed) and each of the Towns, CMS and CPCC. The spreadsheets are located in the following directory: G:\WQxfer\WQ\Phase II Inventory. b. Sort the parcels in the spreadsheet by ascending size and start the evaluation with the smaller parcels first. After sorting, each parcel will be assigned a database number in the first column in the spreadsheet starting with the number one (1) for the smallest parcel. c. Review aerial photographs of the properties on-line through use of Polaris with the "parcel number labels", "streams", "SWIM buffer", "10-ft Contours" and "aerial photography" layers turned on. The parcel will also be highlighted by using the "ID parcel" tool. d. CMSWS staff will print out copies of the map and the ownership information for documentation. The database number for that file will be handwritten on the upper right-hand side of the map and the ownership record stapled behind the map. The hard copies will be filed in a three-ring binder by database number. e. Mark the number of buildings in the appropriate column of the spreadsheet for each parcel. f. Properties with no buildings or a single building are not included in the Phase II process at this time. CMSWS staff will mark the "Applicable" column with "N" and add a comment as to why the property is not applicable to Phase II (i.e. — no building structures). 4. Other parcels containing 2 or more buildings will require further evaluation to determine if applicable to the Phase II process: a. By reviewing the aerial photographs and contours, determine if the property discharges directly into a stream without going through a MS4 system (system maintained by City and County). CMSWS staff can use Mecklenburg County Stormwater Services Interactive Mapping site athttp://www.704336rain.com/disclaimer.html to view storm drain inlets and piping to assist in this evaluation. If the storm drain system meets these criteria, Phase II is applicable to this property. CMSWS staff will mark the "Applicable" column as "Y" and add a comment as to why the property is applicable to Phase II (i.e. storm drainage system discharges directly to a stream). If it is unclear the property drains directly to the surface water, do not mark anything on the spreadsheet. b. Field evaluations will be required for all remaining properties without a "Y" or an "N" in the "Applicable" column. Field evaluations will be conducted in the following manner: 177 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services i. The Phase II Parcel Evaluation Sheet will be used to document applicability. Each step of the flow chart will be circled as evaluated as well as notes related to applicability or non -applicability. ii. The operations or activities that have the potential to pollute stormwater will be noted as well. Photographs will be taken if staff is unclear of applicability. iii. The Phase II Parcel Evaluation Sheet will be stapled behind the ownership records page and re -filed in the appropriate three-ring binder. iv. CMSWS staff will update the spreadsheet with a "Y" or "N" in the "Applicability" column as appropriate. B. SECOND PERMIT TERM CMSWS changed its evaluation procedures for the second Permit term to include facilities with the "significant potential for generating polluted stormwater runoff' in the Pollution Prevention and Good Housekeeping Program described in Section II, Section G.2.a of the Permit. These new procedures are less inclusive than those applied during the first Permit term; therefore, facilities and operations identified for coverage prior to 2011 were left in the program thus going beyond minimum Permit requirements. For the purposes of this Permit, "significant potential for generating polluted stormwater runoff' shall mean that the facility meets both of the following criteria: 1. Exposure of significant materials based on the "Exposure Checklist" included in numbers 12 through 14 of NCDEQ's "No Exposure Certification Form" (NCGNE0000) (see attached Form for Evaluating Exposure of Significant Materials), and 2. No written procedures or controls in place to prevent pollution. Facilities that meet the above criteria are added to the Pollution Prevention/Good Housekeeping Program and the co-permittees that own and/or operate these facilities are required to implement long-term pollution prevention measures to reduce the potential for polluted stormwater runoff, including (but not limited to) the following: 1. Development of a full Stormwater Pollution Prevention Plan. 2. Development of written Standard Operating Procedures (SOPS) for activities on -site that have a significant potential to pollute stormwater. 3. Completion of required inspections. 4. Completion of required pollution prevention training for on -site staff. Based upon guidance documents provided by NCDEQ in the BIMS database, jurisdictions will review several types of municipal operations in their evaluation. Below is a listing of these municipal operation types along with a summary of how each has currently been addressed or will be addressed by CMSWS. 1. Transfer stations — The County operates a total of five (5) solid waste recycling centers, which are currently included in the Pollution Prevention and Good Housekeeping Program. One of these, the Old Compost Central, is no longer open to the public and only receives materials from City operations. It is planned to close in 2023. 2. Fleet maintenance — All fleet maintenance that is performed by the co-permittees is conducted at the facilities that are currently inspected under the Pollution Prevention and 178 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services Good Housekeeping Program. Fleet maintenance not performed at currently inspected sites is contracted to outside vendors. This was verified via emails to co-permittee staff during the week of 9/28/2020 and correspondence can be found on the LAN as follows: Z:\20-21 City Works Server Attachments\PP-5\Emails on vehicle maintenance from Co permittees. 3. Airports — None of the co-permittees operate airports. 4. Animal shelters — The Town of Cornelius is the only Mecklenburg County Phase II jurisdiction that operates an animal shelter. This facility was evaluated in FY2021 utilizing the Facility Exposure Form and was determined not to have a significant potential to pollute. Appropriate measures will be implemented to minimize storm water pollution issues based on this evaluation. 5. Wastewater Treatment Plants - None of the co-permittees operate wastewater treatment plants. 6. Water plants — None of the co-permittees operate water treatment plants. 7. Construction debris sites — Mecklenburg County operates the Foxhole Landfill, which accepts construction and demolition waste. This facility is currently inspected under the Pollution Prevention and Good Housekeeping Program. 8. Transit authority - None of the co-permittees operate public transit systems. 9. Public works operations — Public Works facilities have been evaluated and are currently included in the Pollution Prevention and Good Housekeeping Program. 10. Prisons — None of the co-permittees operate prisons; however, Mecklenburg County does operate two jails (Mecklenburg County Jail Central and Mecklenburg County Jail North), which were evaluated in FYI 4. It was determined that they do not have a significant potential for stormwater pollution and were not be included in the Pollution Prevention and Good Housekeeping Program. The contact for these jails is Captain Mike Greer (704- 336-8544). 11. Emergency service facilities — Emergency service facilities have been evaluated. Mecklenburg County operates the Mecklenburg County Medic facility, which is currently included in the Pollution Prevention and Good Housekeeping Program. The Towns' fire departments operate emergency services along with the individual fire stations. All fire stations owned and operated by the Towns, as well as volunteer fire departments that operate within a co-permittee jurisdiction, were evaluated in FY2020, and were determined not to have a significant potential to pollute. Therefore, these facilities will not be included in the Pollution Prevention and Good Housekeeping Program. 12. Fire stations — All of the co-permittees operate one or more fire stations. All fire stations operated in the Towns are owned by the Towns except one of the four (4) stations in Huntersville and both stations in Mint Hill, which are owned by independent volunteer fire departments (VFDs). All fire stations located in the Towns, as well as several VFD owned and operated fire stations in the County, were evaluated in FY2020 utilizing the Facility Exposure form and were determined not to have a significant potential to pollute. Therefore, these facilities will not be included in the Pollution Prevention and Good Housekeeping Program. 13. Landfills — Mecklenburg County operates one active landfill (Foxhole) and one inactive landfill (Harrisburg Rd.). The inactive site is now the location of the CT Meyers golf course where Mecklenburg County Solid Waste still performs ground water monitoring. 179 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services The Foxhole landfill and the CT Meyers golf course are included in the Pollution Prevention and Good Housekeeping Program. 14. Schools — CMS and CPCC school facilities have been evaluated and are included in the Pollution Prevention and Good Housekeeping Program. Newly added CMS and CPCC schools are identified through the municipal inventory process. All new CMS schools are added to the Pollution Prevention and Good Housekeeping Program for CMS. New CMS schools are inspected as they are added and then are inspected on a rotational basis with all other schools going forward. All new CPCC school facilities to date have been additions to existing campuses which are already included in the Pollution Prevention and Good Housekeeping Program. 15. Parks — On 9/30/2020, the Park and Recreation Director with each co-permittee was contacted and informed that CMSWS wanted to ensure that all park properties with a potential to pollute have been evaluated. They were asked if their parks included facilities with vehicle or equipment maintenance or storage and/or chemical or fuel storage. Mint Hill, Matthews, Davidson, and Huntersville stated that they did not have any such facilities. Cornelius stated that most of their larger parks have a small fuel cabinet where a couple gallons of gas or diesel fuel for equipment and gators is kept. They also keep gators at several parks but do not service vehicles in-house. Based on this information, these facilities do not rise to the level of a significant potential to pollute and will not be included in the Pollution Prevention and Good Housekeeping Program. Pineville reported that they have a Park Maintenance Facility that has vehicle/equipment storage and maintenance as well a chemical storage and diesel fuel tank. This facility was evaluated in FY2021 utilizing the Facility Exposure Form and was determined not to have a significant potential to pollute. Appropriate measures will be implemented to minimize storm water pollution issues based on this evaluation. All email correspondence with co-permittee staff can be found on the LAN as follows: Z:\20-21 City Works Server Attachments\PP-5\Park and Rec emails on facilities.

Police Departments — The six (6) Towns operate Police Departments, but the County does not. The police stations include offices with no significant potential to pollute; therefore, they are not included in the Pollution Prevention and Good Housekeeping Program. 17. Waste recycling centers — The County operates a total of five (5) solid waste recycling centers, which are currently included in the Pollution Prevention and Good Housekeeping Program. One of these, the Old Compost Central, is no longer open to the public and only receives materials from City operations. Plans are to close the facility in 2023. 18. Vehicle maintenance operations — None of the co-permittees operate vehicle maintenance facilities as dedicated municipal operations. All fleet maintenance that is performed by the co-permittees is conducted at their municipal facilities that are currently inspected M Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services under the Pollution Prevention and Good Housekeeping Program. Fleet maintenance that is not performed by the co-permittee is contracted to outside vendors. This was verified via emails to co-permittee staff during the week of 9/28/2020 and correspondence can be found on the LAN as follows: Z:\20-21 City Works Server Attachments\PP-5\Emails on vehicle maintenance from Co permittees 19. Vehicle wash operations - None of the co-permittees operate Vehicle Wash Operation facilities as dedicated municipal operations. Three (3) Phase Il municipal facilities include areas where they wash vehicles and/or equipment as part of their standard operations, including the Towns of Cornelius, Matthews and Huntersville. These operations are inspected annually as part of the inspection of the municipal facility under the Pollution Prevention and Good Housekeeping Program. 20. Pump stations or lift stations - None of the co-permittees operate Pump Station or Lift Station facilities as dedicated municipal operations. Co-permittees purchase, and in some case sell, properties necessitating that the inventory be updated on an annual basis. The process for updating the inventory is described below. 1. Prior to January 3 1 " of every year, staff with CMSWS will use the Mecklenburg County Open Mapping system to obtain an updated inventory of all properties that are owned by the co-permittees, including the County, six (6) Towns, CPCC and CMS. 2. Prior to March 3 1 " of every year, staff will complete a comparison of the updated inventory to the inventory on file from the previous fiscal year. The inventory will be updated with all new co-permittee properties. 3. Prior to May 31st of every year, staff will evaluate the new properties added to the inventory to determine if the properties have a significant potential to pollute as defined above. This process is as follows: a. The most current aerial imagery available will be used to determine if no buildings are located on the property in which case the property will be identified as not having a significant potential to pollute and will not be included in the Pollution Prevention and Good Housekeeping Program. b. The inventory will be updated to indicate that the property was not included in the Program by placing an "N" in the column entitled "Significant Potential to Pollute" and a "N" in the column entitled "Pollution Prevented or Eliminated." A comment as to why (i.e. — no building on property) will be added to the inventory. An Activity Report will be completed in Cityworks to document the identification process for properties with no significant potential to pollute. Staff will email their supervisor regarding completion of this evaluation and indicate the Activity Report number. c. Properties with one or more buildings (excluding single family homes) will be field evaluated and the Form for "Evaluating Exposure of Significant Materials" (see Attachment 2) will be completed. The form is divided into three (3) sections, including Exposure to Precipitation, Above Ground Storage Tanks, and Secondary Containment. If the answer is "Yes" to any of the questions under Exposure to Precipitation or "No" to any of the questions under Above Ground Storage Tanks and Secondary Containment, then the facility has a significant potential to pollute unless: i. Written procedures or controls are in place to prevent pollution; or 181 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services ii. The source(s) of pollution can be permanently eliminated. If either of these two (2) conditions for exclusion from having a significant potential to pollute currently exist or can be developed, then staff will select the appropriate "Yes" or "No" box on the form and indicate under "Comments" at the end of each section the appropriate exclusion option and whether it currently exists or needs to be developed. If no exclusion option exists, then the appropriate box is selected, and no comment provided. d. If the answer is "No" to all the questions under Exposure to Precipitation and "Yes" to all the questions under Above Ground Storage Tanks and Secondary Containment, then the facility does not have a significant potential to pollute. However, there may be pollution sources that are not listed on the form, such as vehicle washing outside or a leaking drum. In such cases, staff will note this under "General Comments" at the bottom of the form. In all such situations, staff must implement immediate actions to remove the pollution source, including issuing a Notice of Violation and/or requiring that SOPS be implemented to eliminate/control the source. e. Staff will complete an Activity Report in Cityworks to document the field evaluation and the Form will be attached. Staff will indicate in the Activity Report whether the property has a significant potential to pollute and recommend a course of action. Staff will submit the Activity Report documenting the completion of the field evaluation to their supervisor for review and follow up. f. The supervisor will review the Activity Report and discuss with staff as necessary. The supervisor will decide the appropriate course of action and the Activity Report will include a description of that action and document when it is completed. For example, if it is decided that there is no significant potential to pollute, the lead staff will explain this in the Activity Report and update the inventory by placing an "N" in the column entitled "Significant Potential to Pollute" and a "N" in the column entitled "Pollution Prevented or Eliminated." The Activity Report number will be indicated in the inventory and then closed. No further action is required. g. If it is decided that there is a significant potential to pollute, but that one of the two (2) exclusion options described above can be implemented, then the supervisor will assign this work to staff and follow up to ensure completion at which point the Activity Report will be updated with a description of the actions taken and the inventory updated by placing a "Y" in the column entitled "Significant Potential to Pollute" and a "Y" in the column entitled "Pollution Prevented or Eliminated." A brief description of the actions completed will be provided in the comment column of the inventory. The Activity Report number will be indicated in the inventory and then closed. No further action is required. h. If it is decided that there is a significant potential to pollute and the two (2) exclusion options cannot be implemented, then the supervisor will explain this in the Activity Report and update the inventory by placing a "Y" in the column entitled "Significant Potential to Pollute" and a "N" in the column entitled "Pollution Prevented or Eliminated." A comment will also be added to the inventory explaining why. The Activity Report number will be indicated in the inventory and then closed. The facility will be added to the Pollution Prevention 182 Charlotle-Mecklenburg STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 WATER �� services and Good Housekeeping Program and the four (4) long-term pollution prevention measures will be implemented as described in this document. i. If it is decided that there is no significant potential to pollute but pollution sources are present at the facility that are not listed on the form, then the supervisor will ensure that staff complete the necessary follow up actions to eliminate the source(s). The Activity Report will be updated with a description of the actions taken and the inventory updated by placing a "N" in the column entitled "Significant Potential to Pollute" and a "Y" in the column entitled "Pollution Prevented or Eliminated." A brief description of the actions completed will be provided in the comment column of the inventory. The Activity Report number will be indicated in the inventory and then closed. No further action is required. j. In some situations, the supervisor may decide that even though a significant potential to pollute does not exist there is a potential to cause negative water quality impacts and sources cannot be effectively eliminated or controlled. In such cases, the supervisor may elect to implement one (1) or more of the four (4) long-term pollution prevention measures described in this document. A brief description of the actions to be undertaken will be provided in the comment column of the inventory. The Activity Report will be updated with a description of the actions taken and the inventory updated by placing a "N" in the column entitled "Significant Potential to Pollute" and a "Y" in the column entitled "Pollution Prevented or Eliminated." A brief description of the actions completed will be provided in the comment column of the inventory. The Activity Report number will be indicated in the inventory and then closed. No further action is required. 4. Prior to June 30th of every year, staff will contact all co-permittees either by email or letter providing a list of all their facilities and/or operations that have been determined to have a significant potential to pollute and are therefore subject to the Pollution Prevention and Good Housekeeping Program. Co-permittees will be asked to respond back with any additional facilities and/or operations that should be added to the list or indicate that the list is complete. The supervisor may assign field evaluations or other follow up actions as necessary based on these responses to ensure that the inventory is updated as necessary. All the above actions will be documented in an Activity Report in Cityworks with all correspondences attached. The end result will be the completion of the updated inventory prior to June 30th of every year that has been verified in writing by each co- permittee. 5. The inventory must be completed by June 30th of every year. 6. If follow up actions are deemed necessary for future fiscal years, the supervisor will be responsible for incorporating these actions into annual Work Plans. 7. The supervisor will work with the Program Manager to update the SWMP to include new properties into the Pollution Prevention and Good Housekeeping Program. 183 / Cherla#e Uecklenburg 4 STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 — November 2022 M WATER �� Services Phase II Municipal Facility Inventory (PP-5) CMS, CPCC, County or Town of XXXX PID Physical Address Property Use No. of Buildings Total Acres Date Evaluated Staff Performing Evaluation Significant Potential to Pollute (Y/N) Pollution Prevented or Eliminated /N Activity Report # Comment / Justification 10 Charlotte Mecklenbur.9 STORM Stormwater Quality Management Program Plan — NPDES # NCS000395 —November 2022 `-`� WATER �� Services Form for Evaluating Exposure of Significant Materials Facility Name (PID): I Facility DB#: Inspector: Date: I Town: Exposure to Precipitation: Are any of the following materials or activities exposed to precipitation, now or in the foreseeable future?
