Phase II MS4 Permit No. NCS000395 1 Section 1: Introduction This document satisfies the annual reporting requirement of Storm Water Permit No. NCS000395 as follows: • Evaluate program compliance, the appropriateness of best management practices (BMPs), and progress towards achieving measurable goals; and • Evaluate the performance and effectiveness of the Storm Water Quality Management Program Plan, herein referred to as the Storm Water Plan. The purpose of the Storm Water Plan is to describe the actions undertaken by the Permittee to ensure compliance with Permit requirements, including all BMPs and their associated measurable goals. Implementation of the BMPs consistent with the provisions of the Storm Water Plan constitutes compliance with the standard of reducing pollutants to the maximum extent practicable as required by the Permit. Charlotte-Mecklenburg Storm Water Services (CMSWS) has developed and is maintaining the Storm Water Plan for Permit No. NCS000395 on behalf of all co-permittees, including Mecklenburg County, Charlotte-Mecklenburg Schools (CMS), Central Piedmont Community College (CPCC), and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill, and Pineville. This Storm Water Plan is available on the following website: http://storm water.charmeck.org (select “Surface Water Quality,” select “Program Overview,” select “Current Storm Water Management Plan” under Phase II Permit at the bottom of the page). Section 2 of this annual report provides background information regarding the implementation of the Storm Water Plan, including a fiscal analysis. Sections 3 through 9 of this document provide the following: • Detailed description of the status of the implementation of the Storm Water Plan, including information on the development and implementation of each major component of the plan between July 1, 2018 and June 30, 2019 (FY2019). Activities and associated schedules for implementation of the Storm Water Plan during FY2019 are contained in the Permittee’s FY2019 Work Plan, which is available upon request. • Description of any proposed changes to the Storm Water Plan, including a justification for these changes and how the changes will impact the effectiveness of the Storm Water Plan. • Summary of data accumulated through the implementation of the Storm Water Plan, including an evaluation of this data. • Assessment of compliance with the Permit requirements, including a description of the specific BMPs implemented and whether the measurable goals for these BMPs have been satisfied. Additional detail regarding these BMPs and measurable goals is provided in Sections 3 through 9 of the Storm Water Plan provided at the above website. Section 10 of this document provides an evaluation of overall program compliance and the effectiveness of the Storm Water Plan as well as the individual BMPs contained in the Plan. Section 11 describes the program modifications to be implemented effective July 1, 2019 to accomplish the intent of the Storm Water Plan and enhance overall Program effectiveness. Section 12 describes the modifications to the Storm Water Plan for FY2020 as a result of the FY 2019 evaluation of the effectiveness of the Plan. Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 2 Section 2: Overview and Funding CMSWS is responsible for developing, implementing, managing and overseeing the Storm Water Plan under the direction of Mecklenburg County’s Water Quality Program Manager. The specific tasks, deadlines and assigned staff for fulfillment of the Storm Water Plan are described in an annual Work Plan. A copy of this Work Plan is available upon request to Mecklenburg County’s Water Quality Program Manager. As specified in the Permit, each co-permittee is responsible for compliance with the terms and conditions of the Permit for storm water activities and watershed specific requirements within their jurisdictional area. Appropriate legal authority has been established by each jurisdiction for implementation of the Storm Water Plan through the adoption of Surface Water Pollution Control Ordinances that prohibit illicit discharges to the MS4 as well as the adoption of post-construction and erosion control ordinances. Mecklenburg County is delegated authority by each jurisdiction to enforce these ordinances. Funding for implementation of the Storm Water Plan is shared by each jurisdiction based on an adopted Funding Strategy. The Phase II budget for FY2020 is $630,748.80 with $531,980.88 (84%) for staff costs and $98,767.92 (16%) for operating costs. Table 1 provides a breakdown of the FY2020 budget by jurisdiction/entity. Table 2 provides a cost breakdown by program task. The Phase II jurisdictions utilize the revenue they receive from their storm water fee to fund the implementation of the Program with the exception of CMS and CPPC, which do not receive revenue from the storm water fee and therefore fund Phase II Program implementation through their general budget. Additional funding information is available upon request, including the documentation for the FY2020 Funding Strategy.

Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 5 Section 3: Public Education and Outreach Program CMSWS has developed and implemented a Public Education and Outreach Program for Mecklenburg County’s Phase II jurisdictions/entities. The 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. 3.1 Implementation Status for FY2019 Table 3 describes the BMPs identified in the Storm Water Plan for the Public Education and Outreach Program and the specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals for the BMPs specified in the plan have been fulfilled. Table 3: BMP Summary Table for the Public Education and Outreach Program BMP Description Implementation Actions Goal Met Yes No Education & Outreach (Brochures, Newsletter, Media Campaign, Social Media, Website, Schools & Commercial) (PE-10) The targeted pollutants, sources and audiences for FY2019 are described in Table 3 of the Storm Water Plan. One of the public education methods used in FY2019 was the distribution of educational materials by staff at events and public meetings as well as when conducting inspections and responding to citizen requests for service. Handouts are also available to the public on the CMSWS website under the “Surface Water Quality” tab by selecting “Pollution Prevention.” The following handouts/brochures/pamphlets have been developed: • A Guide to Used Oil Recycling • Scoop the Poop (proper handling of animal waste) • Only Rain Goes Down The Storm Drain – The Citizen’s Guide to Pollution Prevention • Volunteer Opportunities • A Brief Look at Charlotte-Mecklenburg Storm Water Services – Your Storm Water Fees at Work • Grease Free (proper disposal of grease from Charlotte-Mecklenburg Utilities) • Household Hazardous Waste – What do you do with left over chemicals • Environmental Notices for Homeowners – Disposal into the storm drain is against the law (available in English, Spanish, Chinese, Vietnamese, and Korean) • Environmental Notices for Businesses – Disposal into the storm drain is against the law (available in English, Spanish, Chinese, Vietnamese, and Korean) • Water Watchers door hanger • Household Hazardous Waste slider • Dispose of Leaves Properly postcard • Water Quality Buffers postcard • When Surface Waters Turn Colors (Pollen, Tannin, Iron Bacteria) • Clean Boating Practices • Non-Structural Best Management Practices Handout o Mobile Detailer o Landscapers o Painters o Contractors o Carpet Cleaners o Vehicle Service X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 6 BMP Description Implementation Actions Goal Met Yes No o Food Service o Multi-family o Stone Cutting & Fabrication Industry o Concrete Industry o Commercial Property Management o Asphalt Sealing o Swimming Pool & Spa Industry o Horizontal Directional Drilling • Structural Best Management Practices Handout o Dry Detention o Rain Garden o Sand Filter o Storm water Wetland o Wet Pond During FY2019, educational newsletters were developed and disseminated to the Phase II co-permittees covering the targeted pollutants described above. These newsletters focused on the actions the public should take to reduce pollution, including participating in volunteer programs, and reporting suspected pollution problems. The @StormWaterCM social media accounts (Facebook, Twitter & Instagram) were used as the main method to help disseminate messages to the Towns. Phase II social media contacts were responsible for sharing messages on the Towns’ or institutions’ social media accounts. Due to not using social media, Barbara Monticello with the Town of Pineville was emailed messages to be included in the local town mailer. In order to address compliance with the Goose Creek TMDL, additional social media messages were created for the Town of Mint Hill that focused on reducing bacteria levels in surface waters. Social media messages were also used to promote the sale of tree seedlings and rain barrels by the Mecklenburg County Soil and Water Conservation District. During FY2019, age specific educational information was developed and distributed in schools . In October 2019, science teachers were emailed information on the water quality educational programs being offered. As a result, 21 school presentations were given in the Phase II jurisdiction to 516 students as follows: • 9/28/18: Catawba Stem Festival, 5th grade, 3 classes, 94 students, Flood Plain Model • 3/8/19: Phoenix Montessori Academy, K-8th, 3 classes, 62 students, Journey of a Raindrop & Enviroscape • 4/12/2019: North Mecklenburg High School, 9 grade, 15 classes, 360 students, Presentation and Video on Careers In addition to school presentations, CMSWS conducted the public presentations described in Table 4 and attended the events described in Table 5. During FY2019, a special outreach campaign focusing on reducing bacteria level in our stream s was again utilized. The campaign was called “Scoop the Poop.” The campaign included Social Media Posts and videos, a website banner and additional website information including a story map, vehicle magnets, and a flagging campaign where at select locations piles of animal waste not picked up by owners were “flagged” with a sign that identified harmful bacteria and parasites that could be present in the waste. During FY2019, informational pages covering a wide variety of topics were maintained on the Storm Water Services websi te, including current water quality conditions, storm water pollutants and ways to minimize them, reporting pollution, volunteering, municipal storm water projects/activities, etc. These web pages also provide a means to register for various volunteer init iatives. The targeted pollutants on the pollution prevention pages include: bacteria and pet waste, turbidity, sediment, phosphorus, nitrogen, organics, fertilizers, pesticides, Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 7 BMP Description Implementation Actions Goal Met Yes No yard waste, surfactants, hydrocarbons, pH, and toxic compounds. The targeted audiences include residential, commercial and institutional. The general messages promoted on the web pages are street to stream, only rain should go down the storm drain, and be a Water Watcher/Volunteer. The web pages also provide contacts for reporting pollution problems/concerns and submitting questions to staff. During FY2019, Google Analytics showed CMSWS’s web pages had 376,617 page views, which is an increase of 36.66% from the 275,595 page views in FY2018. This increase is attributed to the increase in social posts and all collateral including the website, and with direct links where possible. The pages most often visited were the Floodplains and Maps, the Homepage, and The Big Spring Clean page. For Industrial/ Commercial Education, staff attended and presented at the Regional Stormwater Partnership of the Carolinas meeting on Storm Water Pollution Prevention (SWPP) service requests. Car maintenance BMP posters were distributed during routine inspections and service requests and also at several auto body shops throughout the county. Media Campaign PE-I(13) During FY2019, a media campaign was developed and implemented to reach residential, commercial, and institutional audiences with information regar ding reporting pollution, volunteering, and flood safety. The campaign included television, radio, online, print, and Out-of-Home ads as well as social media (Facebook, Twitter, Instagram and YouTube). Out-of-Home ads included the 4th Street Garage banner promoting the annual Big Spring Clean and a banner promoting Flood Safety. Print ads included 5 Utility Bill Inserts (UBIs). UBIs are two-sided and cover storm water related topics such as flooding, living in floodplains, storm water pollution indicators, preventing and reporting storm water pollution, volunteering, etc. During FY2019, UBI messages were mailed to 255,000 customers in Charlotte-Mecklenburg once a month for 5 months for a total of 1,275,000 contacts. A summary of media outreach for FY19 is provided below. • Number of television advertising spots developed = 2 (Telemundo & TBSC) • Impressions & Reach of television advertising spots = Impressions at 980,715 & Reach at 13.5% • Number of radio advertising spots developed = 4 - WFAE 1 per each campaign • Impressions & Reach of radio advertising spots = Impressions at 84,000 & Reach at 11.5% • Number of print advertising spots developed = 2 – 4th Street Banner & I-277 Street Banner • Impressions of print advertising spot = Impressions at 265,800 • Number of electronic advertising spots developed = 10+ • Impressions of electronic advertising spots = Impressions at 3,502,153 X Evaluate Effectiveness of Public Education and Outreach Program (PE-9) During FY2019, an evaluation was completed of the Public Education and Outreach Program revealing that the program components and BMPs specified in the Storm Water Plan are performing effectively and efficiently at achieving program goals and that they meet or exceed permit requirements. Provided below is a report of the status of the program’s attainment of the specific measures of success contained in the Storm Water Plan. • Documentation of Storm Water Program Activities - All the measurable goals assigned to the BMPs have been satisfactorily fulfilled and properly documented in CMSWS’s Cityworks and/or the Volunteer Database. • Increasing Awareness – Storm Water Public Opinion Surveys are conducted annually to measure the effectiveness of the Public Education and Outreach Program at improving awareness of water quality issues as well as to assess citizen’s level of concern/interest. The measure of success for the Public Education and Outreach Program is a minimum of 50% of survey responde nts X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 8 BMP Description Implementation Actions Goal Met Yes No indicating they are aware that water flowing into storm drains goes directly to creeks and lakes. For FY2019, 83% of survey respondents indicated awareness, which is an increase of 14% from the 69% in FY2018 69%. The FY2019 survey was completed in September 2019. • Increasing Extent of Exposure – The indicator of success is an increase in the extent of exposure from the previous fiscal year. In FY2019, CMSWS had a total estimated extent of exposure (also referred to as impressions) of 6,063,651, compared to 6,261,262 in FY18. While this number decreased by 3.1%, that is a very small drop in total reach when you take into account that there was very little media for several months during FY2019 caused by the delay created by the development of a new media strategy. Other metrics used to measure program success showed significant increases compared to FY2018 as follows: number of public events attended at 26 in FY2018 and 34 in FY2019 for an increase of 31% and number of presentations conducted at 12 in FY2018 and 19 in FY2019 for an increase of 58%. The FY2019 program evaluation revealed that focusing public education and outreach efforts on the targeted pollutants, sources, audiences, and issues described in Table 3 of the Storm Water Plan has enabled program goals to be achieved effectively and efficiently. Moving forward into FY2020 the media campaign will continue to focus on the digital platforms to reach specific demographics within the targeted audience more effectively. In addition, the second year of the Scoop the Poop Campaign first conducted in FY2018 was again highly effective at educating and involving citizens in activities to protect and restore water quality and will be continued in FY2020 with modifications to involve Home Owners Associations. As part of the overall program evaluation, recommendations for improvement have been made as described in Section 3.3 below. These recommendations will be implemented in FY2020 through the execution of the annual Work Plan.

As described in Table 3, a new media strategy was implemented in FY2019 that allowed a large portion of CMSWS’s outreach to go to a digital platform. This significantly enhanced capabilities for targeting messages to specific audiences for improved effectiveness. 2 Update the school presentation flyer and add Stormy visits to schools. Increase awareness ID-5(b) David Caldwell Completed. Update flyer developed. 3 Develop a new vehicle wrap for the truck that pulls the boat that focuses on lake water quality. Increase awareness ID-5(b) David Caldwell Completed. In FY2019 a Truck Wrap focusing on lake water quality was designed and is currently being edited. The vehicle is to be wrapped in FY2020. 4 Continue to promote Stormy at events and incorporate the Stormy image into as many new creative materials as possible. Increase awareness ID-5(b) David Caldwell Completed. In FY2019 Stormy was used in multiple ways, including parades, educational events, social media posts, staff events, Storytime at libraries, etc. Stormy also served as the design for the volunteer appreciation magnet, t-shirts, and the new vehicle wrap. 5 Continue to provide participation and leadership to the Storm Water Regional Partnership of the Carolinas in an effort to provide a unified, regional approach to storm water education and outreach. Increase awareness ID-5(b) David Caldwell Completed. Mecklenburg County continues to be an active member of the RSPC. The RSPC sponsored an elected officials storm water education workshop in February 2019 and continues to promote storm water Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 11 # Improvements Identified for Implementation in FY19 Desired Result Program Element Responsible Staff Implementation Status education through media advertising throughout the region. 3.3 Improvements Identified for Implementation in FY2020 The following improvements in the Public Education and Outreach Program have been identified for implementation in FY2020 to improve program effectiveness: 1. Promote Stormy (mascot) for various education events and promotional material. 2. Investigate creating a children’s video using Stormy to promote storm water education. 3. Develop a new presentation for schools to educate students on benthic macroinvertebrates and stream ecology, but without the need for live species in the classrooms. 4. Develop a plan for education regarding the use and negative impacts of coal tar sealants. 5. Partner with the Regional Stormwater Partnership of the Carolinas and JC Smith University on a WRRI grant to improve public awareness and education of storm water / water quality issues in underserved communities in Charlotte. 6. Work with the LUESA Education team to sponsor an Earth Day 50 year anniversary celebration event. Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 12 Section 4: Public Involvement and Participation Program CMSWS has developed and implemented a Public Involvement and Participation Program for Mecklenburg County’s Phase II jurisdictions/entities. The 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. 4.1 Implementation Status for FY2019 Table 7 describes the BMPs identified in the Storm Water Plan for the Public Involvement and Participation Program and the specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals for the BMPs specified in the plan have been fulfilled. Table 7: BMP Summary Table for the Public Involvement and Participation Program BMP Description Implementation Actions Goal Met Yes No Conduct Phase II Public Meeting (PI-1) On January 17, 2019, CMSWS staff gave a presentation to Storm Water Advisory Committee (SWAC) regarding activities performed to comply with Phase II Permit requirements, which included a PowerPoint presentation. In addition, staff requested input from SWAC and the public regarding storm water issues and the storm water program as a whole. No input was provided. X Implement Adopt-A- Stream Program (PI- 2) During FY2019, 26 groups that included a total of 499 volunteers donated 1,272.25 hours toward the completion of 48 stream cleanups resulting in the removal of 5,912 pounds of trash and debris from 42.57 miles of streams in Mecklenburg County’s Phase II jurisdiction. The breakdown of miles of streams cleaned up in each jurisdiction is as follows: • 6.6 miles in Davidson • 10.47 miles in Huntersville • 4.43 miles in Matthews • 25.17 miles in Mecklenburg County • 3.42 miles in Pineville. The names of the stream segments cleaned up include Caldwell Station, Four Mile Creek, Gar Creek, Irvins Creek, Irwin Creek, Lake Davidson, Little Sugar Creek, McAlpine Creek, Ramah Creek, Rocky River West Branch, Stewart Creek, and Torrence Creek. There is a total of 21.24 stream miles adopted in the Phase II jurisdictions. All data and information regarding these cleanups is available in the County’s Volunteer Database. X Implement Storm Drain Marking Program (PI- 3) During FY2019, seven (7) groups that included a total of 29 volunteers donated 40.75 hours toward marking 279 storm drains in Mecklenburg County’s Phase II jurisdictions. All data and information regarding the storm drain marking activities was input into the County’s Volunteer Database. The breakdown by jurisdiction is as follows: • Huntersville: 1 group, 7 members, 10.5 hours, 106 markers • Matthews: 3 groups, 18 members, 22 hours, 104 markers • Mint Hill: 1 group, 2 members, 4 hours, 17 markers • Davidson: 2 groups, 2 members, 4.25 hours, 52 Markers X Conduct Annual Surface Water Clean The annual surface water cleanup refer red to as the “The Big Spring Clean” was completed on May 30, 2019. A summary of the event results is provided below: • Number of Staffed Sites = 8 • Total Number of Volunteers = 606 X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 13 BMP Description Implementation Actions Goal Met Yes No Up (PE-I(4)) • Total Miles of Streams/Shoreline Cleaned = 19 • Total Number of Trash Bags Filled = 1,122 • Total Number of Recycling Bags Filled = 2 • Total Pounds of Trash Collected = 25,155 pounds or 12.58 tons Implement Volunteer Monitoring Program (VM) During FY2019, the volunteer monitoring program was successfully implemented in the Phase II jurisdictions with the maintenance of two (2) sites as follows: • Torrence Creek Greenway Site on McDowell Creek maintained by the Summers Family – 4 samples collected • Squirrel Lake Park Site on McAlpine Creek maintained by Mariya Narodyn – 3 samples collected Samples collected were analyzed for turbidity, pH, D.O. and temperature. Both volunteer monitoring sites are located in TMDL watersheds. No pollution sources were identified as a result of the monitoring activities. In addition, the program added two (2) activities during FY19, including Streamside Visual Assessments and Streamside Snapshot (pilot stage) to help increase volunteerism. X Conduct Annual Volunteer Appreciation Event (PE-I(14)) In FY2018, the number of volunteers with CMSWS grew to such a large number, it was no longer feasible to hold a specific appreciation event without excluding a large number of volunteers due to budget constraints. In FY2019, CMSWS developed a “Thank You” campaign that recognized an overall “Volunteer of the Year” along with recognizing a volunteer from each of our volunteer programs. As a part of the campaign, car magnets were designed and distributed at events. The magnets promote clean water, while also help to increase awareness of our programs. T-shirts were designed for the volunteers of the year with the same advertising strategy in mind. Each volunteer of the year group was the focus of a newsletter that went out to all volunteers. Newsletter recipients were posted on all social media channels. X Evaluate Effectiveness of Public Involvement and Participation Program (PI-6) During FY2019, an evaluation was completed of the Public Involvement and Participation Program revealing that the program components and BMPs specified in the Storm Water Plan are performing effectively and efficiently at achieving program goals and that they meet or exceed permit requirements. Provided below is a report of the status of the program’s attainment of the specific measures of success contained in the Storm Water Plan. • Documentation of Storm Water Program Activities – All the measurable goals assigned to the BMPs have been satisfactorily fulfilled and properly documented in CMSWS’s Cityworks and/or the Volunteer Database. • Increasing Number of Volunteers – The indicator of success is an increase in the number of volunteers compared to the previous fiscal year. In FY2019, countywide the number of volunteers was 4,622, which represents a 3.5% increase from 4,464 in FY2018. In the Phase II jurisdictions alone, the number of volunteers participating in Adopt-A-Stream, Storm Drain Marking and the Big Spring Clean totaled 1,134 in FY2019, which is an increase of 14% compared to the 995 volunteers in FY2018. X 4.2 Status of Improvements Identified for Implementation in FY2019 Table 8 provides the status of improvements in the Public Involvement and Participation Program that were identified in FY2018 for implementation in FY2019.

During FY2019, volunteer events were posted on the following community pages: Catawba RiverKeeper Foundation, Ducks Unlimited, Charlotte Agenda, Charlotte Five, Volunteer Match, Hands On Charlotte, and Work Green. 4.3 Improvements Identified for Implementation in FY2020 The following improvements in the Public Involvement and Participation Program have been identified for implementation in FY2020 to improve program effectiveness: 1. Develop and Adaptive Management Strategy to increase community involvement. 2. Research creating an intern position to help with implementation of the above Strategy. 3. Update the volunteer web pages to be more informative and eye catching. 4. Investigate the use of a public interface calendar such as “Team Up” to advertise publicly open volunteer events. 5. Create a monthly newsletter aimed at volunteers to create motivation and notify them of upcoming events. 6. Create monthly volunteer spotlights to promote volunteerism and praise volunteers. 7. Target specific neighborhoods where storm drains have not been marked and develop marketing to get them involved with the Strom Drain Marking program. Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 15 Section 5: Illicit Discharge Detection and Elimination Program CMSWS has developed, implemented and enforced an Illicit Discharge Detection and Elimination (IDDE) Program in Mecklenburg County’s Phase II jurisdictions/entities. The 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 storm water except discharges pursuant to a NPDES Permit (other than the NPDES Permit for discharges from the municipal separate storm sewer) and discharges resulting from fire-fighting activities as well as incidental non-storm water discharges or flows that are not significant contributors of pollutants. 5.1 Implementation Status for FY2019 Table 9 describes the BMPs identified in the Storm Water Plan for the IDDE Program and the specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals for the BMPs specified in the plan have been fulfilled. Table 9: BMP Summary Table for the IDDE Program BMP Description Implementation Actions Goal Met Yes No Maintain Storm Sewer System Maps (ID-1) In FY2019, 174 new outfalls and 174 new inlets were added to the storm sewer inventory for Phase II jurisdictions/entities. With these additional points, the total current inventory in Phase II jurisdictions/entities is 7,051 outlets and 34,623 inlets. X Conduct Field Screening for Non-Storm Water Flows (ID-2) ESRI Arc GIS is used to track outfall inspections conducted under ID-6, ID-9 and PP-2 (including CPCC and CMS). A written SOP was reviewed, and training was provided to staff for the use of the new layer for performing outfall inspections of existing features and to add new outfalls. During FY2019, a total of 50 outfalls were inspected in the Phase II jurisdictions under this program element. No significant pollution sources were identified under this program element. No illicit discharges were detected through these inspections. X Enforce Surface Water Pollution Control Ordinance (ID-3) During FY2019, Notice of Violation (NOV) protocols, procedures and templates were reviewed. The applicable ordinances, notice of violation and enforcement decision-making process and penalty/enforcement guidance were also reviewed, but no changes were necessary. During FY2019, a total of 15 written NOVs were issued in the Phase II jurisdictions as follows: Cornelius – 2; Davidson – 1; Huntersville – 3; Matthews – 2; Mecklenburg County – 3; Mint Hill – 2; and Pineville – 2. The types of NOVs and/or the materials released were as follows: motor oil – 2; other - 3; paint - 1; sediment - 1; sewage – 5; wash water – 3. All violations were corrected and remediated as necessary. One (1) penalty was assessed on August 20, 2018 to the West Bloom Acres Mobile Home Park in the amount of $1,077 for the illicit discharge of sewage from a broken sewer line at 8746 Little Brim Lane in Charlotte. The penalty was paid in full within 30 days of assessment. X Implement Water Quality Monitoring Program (ID-4) During FY2019, CMSWS performed the following routine monitoring in the Phase II jurisdictions: monthly discrete grab sampling at 10 fixed stream monitoring sites (referred to as Fixed Interval Monitoring or FIM) for a total of 120 events and 1851 individual parameter results; annual benthic macroinvertebrate community sampling at 12 fixed stream sites; and three (3) fish community samples. Monitoring site locations are provided in Figure 1. More information regarding these monitoring activities is provided below. Additional grab samples were completed on an as needed basis. The program administers a X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 16 BMP Description Implementation Actions Goal Met Yes No quality assurance program plan approved by NCDENR in 2009, which contains several Standard Operating Procedures and Standard Administrative Procedures. The program renewed its NCDENR water quality field parameter certification (#5235) in September 2019 and its biological laboratory certification in November 2018. Develop and Implement Fixed Interval Stream Monitoring Program (ID-4.1) During FY2019, Fixed Interval Monitoring was conducted on the 2nd Tuesday of every month at 10 sites throughout the Phase II jurisdictions (see Figure 1, MC2A1, MC3E are not FIM sites). At each site, samples were 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) were collected in the first month of each quarter. Thirty-one (31) baseflow action level exceedances were detected during the year. The exceedances at MC40C were associated with active greenway construction immediately downstream. Exceedances of total phosphorus at MY14 and MY9 were associated with package wastewater treatment plant discharges in the watershed. Table 10 identifies the Baseflow Action and Watch level exceedances identified through Fixed Interval Monitoring performed in the Phase II jurisdictions during FY2019. X Develop and Implement Benthic/Habitat Monitoring Program (ID-4.3) During FY2019, benthic macroinvertebrate bioassessments were conducted at 12 sites in 10 streams within the Phase II jurisdictions, including McDowell Creek (MC2, MC2A1, MC4; Huntersville), Torrence Creek (MC3E; Huntersville), Clarke’s Creek (MY10; Huntersville), Gar Creek (MC50; Huntersville), West Branch Rocky River (MY1B; Davidson), Irvins Creek (MC36; Matthews), Fourmile Creek (MC40C; Matthews), Duck Creek (MY14; Mint Hill), Clear Creek (MY8; Mint Hill), and Goose Creek (MY9; Mint Hill). The Mecklenburg County Water Quality Program Stream Bioassessment Standard Operating Procedures that were used are based on benthic macroinvertebrate sampling methods developed by the NCDEQ Biological Assessment Branch. Taxa richness for the pollution intolerant groups, Ephemeroptera, Plecoptera and Trichoptera, and the North Carolina Biotic Index were calculated and used to assign a State biological classification to each site. Eight (8) of the 12 sites were given a Stream Bioclassification of FAIR, including: McDowell Creek (MC2, MC2A1, MC4; Huntersville), Torrence Creek (MC3E; Huntersville), Clarke’s Creek (MY10; Huntersville), Gar Creek (MC50; Huntersville), Irvins Creek (MC36; Matthews), Fourmile Creek (MC40C; Matthews), and Duck Creek (MY14; Mint Hill. Four (4) streams were rated GOOD-FAIR, including Gar Creek (MC50; Huntersville), West Branch Rocky River (MY1B; Davidson), Clear Creek (MY8; Mint Hill), and Goose Creek (MY9; Mint Hill). Stream habitat assessments were also conducted at each of the 12 sites using the Enhanced version of the Mecklenburg Habitat Assessment Protocol (EMHAP). Scores ranged from 67.4 (Impaired) to 153.4. McDowell Creek above Gilead Road received a EMHAP score of 153.4 which reflects the improvements to the stream channel stability and in-stream habitat quality due to the recent stream restoration work. There appears to be a water quality issue in Duck Creek as the in-stream habitat was highly rated but the rating for the benthic community was low, indicating that h abitat was not a limiting factor. There is an ongoing problem with the Ashe Plantation Waste Water Treatment Plant upstream of the monitoring location that negatively impacted the water quality in Duck Creek. Data indicated that the rural and suburban streams are recovering from the droughts that Mecklenburg County experienced in 2002, 2007 and 2008. X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 17 BMP Description Implementation Actions Goal Met Yes No Develop and Implement Fish Monitoring Program (ID-4.4) During FY2019, fish community assessments were conducted at three (3) sites in Mecklenburg County’s Phase II jurisdiction, including McDowell Creek (MC2, MC4; Huntersville), and Gar Creek (MC50; Huntersville). In fiscal year 2019, all three (3) sites where within the Town of Huntersville (MC2, MC4, and MC50). CMSWS follows the NCDEQ Fish Community Assessment methods which includes electrofishing wadable streams for a 200m stretch; collecting, identifying, measuring, and counting all fish collected. Data was then entered into a database that calculates the North Carolina Index of Biotic Integrity (NCIBI) score for each record. These methods are utilized so data from Mecklenburg County can consistently be compared to other locations throughout North Carolina. Of the three (3) Phase II sites that were sampled this year, McDowell Creek at Beatties Ford Road (MC4) scored the highest with a Good-Fair Rating (42). Historically, MC4 has been rated as Poor or Fair. The FY2019 rating is the highest rating since 2005 when MC4 scored a 42 as well and this indicates that the stream can support a healthy fish community. MC2 located upstream of MC4 in the McDowell Creek watershed received a NCIBI score of 32 and was rated Poor. This Poor rating suggests that this sampling location does not support a healthy fish community. This rating is consistent with the last four (4) sampling events dating back to 2009. The third site on Gar Creek (MC50) received a NCIBI score of 36 and was rated Fair. This Fair rating suggests that this sampling location does not support a healthy fish community. This rating is consistent with the last 4 sampling events dating back to 2009. X Water Quality Monitoring Data QA/QC (ID-4.6) The data from the various physical, chemical, and biological monitoring activities performed by CMSWS is maintained in a controlled Microsoft Access data repository, with user restrictions. To ensure the highest standards of laboratory data, duplicate samples for each site are collected each year. Field blanks, bottle blanks, DI water blanks, and trip blanks are combined into Event Blanks for each sampling run. Of 653 blanks collected during FY2019, one (1) exceeded the minimum detection limit for Bromide on 7/5/18 at 0.0077 mg/L during water intake sampling. 6726 laboratory sample records were reviewed and approved or rejected as appropriate. Additional review of field data and biological data occurred on an as-needed basis throughout the year. X Problem Area Identification and Elimination (ID-4.7) CMSWS uses a Stream Use Support Index referred to as SUSI to assess general water quality conditions in the Phase II jurisdictions based on data collected. SUSI is used as one of CMSWS’s IDDE tool. SUSI overall continues to fluctuate between 67 and 71, on the lower side of historical records. Again, 10 out of 12 fixed interval monthly sampling events have been after storm events, leading to elevated sediment and bacteria loads in the streams. One (1) site however, MY10, was showing elevated total phosphorus and metals concentrations. This watershed has been investigated before, but no definitive source has been identified. Starting in June 2019, three (3) additional sites were added to the fixed interval run to help bracket this watershed to determine the most likely potential areas of contribution to these elevated concentrations. X CMANN (ID-4.10) In FY2019 CMSWS conducted continuous automated monitoring or CMANN activities at 7 sites in the Phase II jurisdictions resulting in the collection of 290,022 QA/QC accepted data points (~86.1% data acceptance rate). All data collected was evaluated for the identification of potential pollution problems and general water quality trends. Current data can be observed on the following website: http://cmann.mecknc.gov. CMANN data is used to calculate the Stream Use Support Index (SUSI), which is a general indicator of water quality conditions in our streams. This index was made available to the public on the website as follows: http://stormwater.charmeck.org (select “Water Quality” at the top of the page). The Phase II CMANN sites include MC4 – McDowell Creek Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 18 BMP Description Implementation Actions Goal Met Yes No (Huntersville), MC40D – Four Mile Creek (Matthews), MC50 – Gar Creek (Huntersville), MY1B – West Branch Rocky River (Davidson), MY8 – Clear Creek (Mint Hill), MY9 – Goose Creek (Mint Hill), MY10 – Clarke Creek (Huntersville). In fiscal year 2019, CMSWS’s CMANN equipment did not observe or detect any pollution problems in the Phase 2 jurisdictions. Beginning in 2016, CMSWS began integrating new hardware into all monitoring sites throughout Mecklenburg County. As of July 24, 2019, four (4) of the seven (7) Phase II sites have been converted to the new EXO technology. All sites will be converted by FY2021. In FY2020, CMANN staff will remain diligent in maintaining the equipment to ensure that we retain the highest quality data possible. Quality Assurance Project Plan Administration (QAPP) CMSWS administers a QAPP for the purpose of standardizing monitoring activities and protocols in accordance with approved methods. Staff were evaluated for possible sample collection error while performing monitoring activities and no problems were noted. All procedures were reviewed and revised as needed and several routine monitoring programs were audited. No corrective actions were warranted. X Public Outreach Program for Illicit Discharges & Improper Waste Disposal (ID-5) During FY2019, CMSWS implemented a public outreach program to infor m public employees, businesses, industries and the general public of the hazards associated with illicit discharges and improper disposal of wastes. This outreach campaign includes instructions for properly reporting these problems to CMSWS. During FY2019, television and radio ads, as well as social media, handouts and brochures were 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. 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 Storm Water Pollution Contr ol Ordinance(s) through the use of “Environmental Notices.” These notices are distributed by staff when responding to citizen requests for service, conducti ng facility inspections and performing other field activities. PE-10 and PE-I(13) on pages 5 and 7 describe additional outreach efforts completed in FY2019. Beginning in FY2015, municipal employees who have the potential to observe a water quality problem were providing training using a video entitled “Water Pollution: What to do?”. The video teaches what water pollutants look like, and provides the proper contacts to report pollution problems. By September 30, 2015, field staff in the following Mecklenburg County programs completed this training: Air Quality, Code Enforcement, Solid Waste, Environmental Health, Social Services, Parks and Recreation, and the Sheriff’s Office. The following employees at the Towns, CPCC and CMS also completed this training: maintenance workers, firefighters, policemen, public works and utility workers, and parks and recreation. According to the Storm Water Plan, all municipal employees who have the potential to observe a water quality problem will receive training at a minim um of once during the five (5) year permit term. The above described training fulfills this requirement for the permit term ending November 10, 2016. The second round of training will be completed prior to end of the next permit term on February 16, 2022. X Conduct Follow up Inspections and Respond to Citizen Requests and During FY2019, staff responded to 123 service requests regarding potential water quality problems in the Phase II jurisdictions. Ten (10) of these service requests were emergency responses. The most common type of service requests other than land development and buffer issues, involved the discharge and/or dumping of potential surface water/storm water pollutants. The most common pollutants observed were: X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 19 BMP Description Implementation Actions Goal Met Yes No Emergencies (ID-6) • Petroleum Fuels = 11 • Sewage = 12 • Sediment = 5 • Wash water = 4 • Motor Oil = 5 As a result of the 123 service requests responded to there were a total of 56 problems detected and 56 problems corrected in Phase II jurisdictions during FY2019. Table 11 below provides data regarding the number and type of service requests received by category in each of the Phase II jurisdictions. Stream Walk/Outfall Inventory & Inspection/ Dry Weather Flow Analysis (ID-8) During FY2019, streams were walked in the Phase II jurisdictions in conjunction with the Phase I stream walks in the City of Charlotte. Policies and procedures for the stream walk program were reviewed and updated as necessary. Staff training was performed on 10/23/2018. Stream walks began on 11/1/2018 and were concluded on May 16, 2019. During FY2019, staff walked approximately 58.62 stream miles in the Phase II (51.78) and ETJ jurisdictions (6.84). The following miles were assessed within each municipal boundary (see Figure 2): 27.10 miles in Matthews, 22.73 miles in Mint Hill, 1.86 miles in Pineville, and 0.08 miles in Stallings. 6.84 miles were walked in the ETJ areas of the Towns. As a result of stream walk activities, 157 features were mapped in Matthews, 95 in Mint Hill, 4 in Pineville, 3 in Stallings, and 25 in the ETJ areas. In all, there were 284 points or features mapped, 63 outfalls inspected, 151 new outfalls identified, and 103 fecal coliform samples collected. Seven (7) of these samples resulted in bacteria action level exceedances (>3000 col/100ml). No exceedances above the action level for total phosphorus were detected (0.50 ppm). Two (2) buffer/floodplain disturbances were identified and reported. No illicit discharge pollution sources were observed during 2019 Phase II stream walk activities. All monitoring data generated under this program was WQ/QCed prior to incorporated into GIS. Overall, stream walk data was collected with consistency in the FY2019 season. X Illicit Discharge Elimination Program (IDEP) (ID-9) The purpose of the Illicit Discharge Elimination Program (IDEP) program is to support and enhance Illicit Discharge Detection and Elimination (IDDE) efforts in Mecklenburg County. The identification of pollution sources is accomplished by investigating business corridors and industrial facilities in Mecklenburg County. During FY2019, IDEP activities were successfully implement in the Phase II jurisdictions. As a result, 17 storm water outfalls were inspected and one (1) Notice of Violation was issued. In addition, seven (7) NPDES Permitted industrial facilities were inspected. All IDEP inspection results were followed up on and corrective actions implemented as necessary. X Used Oil Facility Inspections (ID-U) The purpose of the used oil facility inspections is to ensure the proper handling and disposal of used oil and to identify and elimination pollution sources threatening downstream water quality conditions. In FY2019, the scope of this program was broadened to include facilities that conduct automotive repair and maintenance, but do not accept used oil from the public. This program update was conducted to more effectively identify and eliminate pollution sources within the Phase II jurisdictions. In FY2019, two (2) inspections were conducted at vehicle maintenance facilities within the Phase II jurisdictions, including: • Action Auto & Towing, 8621 Fairview Road, Mint Hill, inspected on March 13, 2019. Inspection Result: Notice of Violation (NOV) issued for discharges of oil to the ground from various sources. The facility conducted site remediation and the NOV was resolved on March 20, 2019. A disposal manifest was provided. • Woodies Auto Service, 179 Davidson Gateway Dr, Davidson, inspected on April 1, 2019. Inspection Result: Report was issued as “Unsatisfactory”. Issues included improper storage of motor oil, brake cleaner and Purple X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 20 BMP Description Implementation Actions Goal Met Yes No Power cleaner. A follow up inspection was performed, and the storage issues were resolved. An online interactive map is posted on CMSWS’s website to assist citizens in locating a facility that accepts used oil and other automotive wastes. The link is as follows: http://maps.co.mecklenburg.nc.us/website/recyclecenters/ Evaluate Effectiveness of IDDE Program (ID-10) During FY2019, an evaluation was completed of the effectiveness of the BMPs for the IDDE Program as described in the latest version of the Storm Water Plan. Section 5.3 below lists those improvements identified for implementation during FY2020 as a result of this evaluation. Section 5.2 below describes the status of the implementation of the improvements identified in FY2018. The FY2019 program evaluation revealed that program components and BMPs specified in the Storm Water Plan are performing effectively and efficiently at achieving program goals and that they meet or exceed permit requirements. Provided below is a report of the status of the program’s attainment of the specific measures of success contained in the Storm Water Plan. • Documentation of Storm Water Program Activities – All the measurable goals assigned to the BMPs have been satisfactorily fulfilled and properly documented in CMSWS’s Cityworks and/or the Volunteer Database. • Increasing Pollution Problems Identified – The indicator of success is an increase in the ratio of the number of Notices of Violation issued to IDDE inspections conducted compared to the previous fiscal year. In FY2019, the ratio was 0.87 based on 17 NOVs issued to 196 inspections conducted. This is the highest ratio recorded to date indicating a significant improvement in this measure of success (see Figure 3). In addition, IDDE inspections also identified 61 problems with 61 resolved for a ratio of 100%. In addition to the metrics above, sections of the IDDE manual and program SOPs were reviewed during FY2019 and updated to reflect current procedures and practices. The IDDE program currently includes a priority basin approach in addition to an increased fecal coliform monitoring frequency, business corridor inspections, continuous automated monitoring, multi-family complex sewer collection inspections, industrial facility inspections, a pet waste education campaign, outfall inspections, and stream walks conducted in 50-acre drainage watersheds. Quarterly “think-tank” meetings to discuss IDDE ideas where continued in FY2019. These meetings were used to review outstanding issues, and brainstorm future initiatives.

Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 27 Section 6: Construction Site Storm Water Runoff Control Program CMSWS has developed, implemented and enforced a Construction Site Storm Water Runoff Control Program for addressing the discharge of sediment and other pollutants from construction sites in Mecklenburg County’s Phase II jurisdictions. The goal of the Construction Site Storm Water Runoff Control Program is to reduce pollutants in storm water runoff from construction activities that result in a land disturbance of greater than or equal to one (1) 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. 6.1 Implementation Status for FY2019 Table 13 describes the BMPs identified in the Storm Water Plan for the Construction Site Storm Water Runoff Control Program and the specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals for the BMPs specified in the plan have been fulfilled. Table 13: BMP Summary Table for the Construction Site Storm Water Control Program BMP Description Implementation Actions Goal Met Yes No Enforce Erosion Control Ordinances (CS-1) During FY2019, a total of 72 new projects were permitted in Mecklenburg County with a total of 789.7 acres disturbed. 1,676 erosion control inspections were performed with 16 Notice of Violations (NOV’s) issued. Five (5) penalties were assessed for a total of $26,250. $17,500 in penalties has been collected. Provided below are the totals for the Phase II jurisdictions. • Cornelius: 200 inspections conducted, 2 NOV’s issued, and 2 penalties assessed with $8,750.00 paid. • Davidson: 83 inspections conducted, 4 NOV’s issued, and 3 penalties assessed with $6,750.00 paid. • Huntersville: 728 inspections conducted and 1 NOV issued. • Matthews: 245 inspections conducted and 2 NOVs issued. • Mint Hill: 300 inspections conducted, 4 NOVs issued, and 1 penalty assessed with $2,000.00 paid. • Pineville: 121 inspections conducted and 3 NOVs issued. X Erosion Control Education (CS-2) Three (3) erosion control educational programs were conducted during FY 2019. They occurred on October 22, 2018, January 23, 2019 and May 9, 2019. There were a total of 371 paid attendees for the three (3) office programs, and 58 completed the online module, with 335 passing the test. X Evaluate Effectiveness of Erosion Control Program (CS-3) During FY2019, an evaluation was completed of the effectiveness of the BMPs for the Construction Site Storm Water Control Program as described in the latest version of the Storm Water Plan. The evaluation revealed that the Program is successful at addressing the discharges of sediment and other pollutants from construction sites in Phase II jurisdictions. Three (3) improvements are recommended for implementation in FY2020 based on this evaluation as described in Section 6.3 below. Provided below is a report of the status of the program’s attainment of the specific measures of success contained in the Storm Water Plan. • Documentation of Storm Water Program Activities: All the measurable goals assigned to the BMPs have been satisfactorily fulfilled and properly documented in CMSWS’s Cityworks and/or the Volunteer Database. • Improved Compliance: The indicator of success is a decrease in the ratio of the number of Notices of Violation issued to erosion control inspections X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 28 BMP Description Implementation Actions Goal Met Yes No conducted compared to the previous fiscal year.

Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 30 Section 7: Post-Construction Site Runoff Control Program CMSWS has developed, implemented and enforced a Post-Construction Site Runoff Control Program for addressing post-construction storm water runoff from new development and redevelopment projects in Mecklenburg County’s Phase II jurisdictions. The goal of the Post- Construction Site Runoff Control Program is to reduce pollutants in storm water runoff during post-construction conditions at new developments and redevelopments, including public transportation maintained by the permittee, that disturb greater than or equal to one acre. Developments and redevelopments disturbing less than one acre are included in the program if it is part of a larger common plan of development or sale that would disturb one acre or more. 7.1 Implementation Status for FY2019 Table 15 describes the BMPs identified in the Storm Water Plan for the Post-Construction Site Runoff Control Program and the specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals for the BMPs specified in the plan have been fulfilled. Table 15: BMP Summary Table for the Post-Construction Site Runoff Control Program BMP Description Implementation Actions Goal Met Yes No Implement Post-Const. Storm Water Ordinances (PC-1) During FY2019, a total of 72 new projects were permitted for compliance with post- construction ordinance requirements in Mecklenburg County’s Phase II jurisdictions with a total of 789.7 acres disturbed. The Storm Water Administrator worked with staff of the Permitting & Compliance Program to ensure the effective and efficient implementation of ordinance requirements, which included making 13 formal ordinance interpretations that were logged and recorded. The Administrator also completed an annual review of the post-construction ordinances and the supporting Administrative Manual and determined that no changes were necessary. During FY2019, compliance with post-construction ordinance requirements involved 19,888 staff hours at an estimated cost of $1,702,454.82. X Implement BMP Inspections (PC-2) During FY2019, a total of 596 BMP inspections were completed in the Phase II jurisdictions (see Table 16) involving 728 CMSWS staff hours at an estimated cost of $54,559.01. Follow up activities were performed as necessary to ensure compliance and all findings were successfully documented in the Cityworks database. One (1) notices of violation was issued and no fines were assessed as a result of these inspections. During FY2019, an inventory was maintained of projects with structural stormwater control measures installed and implemented for compliance with post-construction ordinance requirements at new development and redeveloped at public and private sector sites. As of June 30, 2019, the inventory included 800 structural stormwater control measures (see Table 17). X Implement a Program to Educate and Assist Developers (PC-3) On December 6, 2018, a training event was held to educate the community on the requirements of the Post-Construction Runoff Control Program with approximately 120 persons attending. The training was held jointly with the City of Charlotte and lasted approximately six (6) hours. The training also included a history of Mecklenburg County’s water resources and information regarding compliance with the water quality buffer requirements. X Evaluate Effectiveness of Post- Construction Control During FY2019, an evaluation was completed of the Post-Construction Site Runoff Control Program revealing that the program components and BMPs specified in the Storm Water Plan are performing effectively and efficiently at achieving program goals and that they meet or exceed permit requirements. The documentation of the evaluation is included as Attachment 1. Provided below is a report of the status of X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 31 BMP Description Implementation Actions Goal Met Yes No Program (PC-5) the program’s attainment of the specific measures of success contained in the Storm Water Plan. • Documentation of Storm Water Program Activities - For the FY2019 program assessment, an evaluation of the Cityworks database has revealed that CMSWS staff effectively documented the completion of Work Plan activities that demonstrate achievement of each of the measurable goals for the BMPs associated with this program. • Improved Compliance - The indicator of success is a decrease in the ratio of the number of noncompliant BMPs to inspections conducted compared to the previous fiscal year. For FY2019, the ratio was 0.686 based on 409 noncompliant BMPs to 596 inspections conducted. This represents a decrease in noncompliance from a ratio of 0.813 in FY2018; however, it represents an increase compared to the other five (5) previous fiscal years (see Figure 5). This indicates a slight measure of success, but additional work is needed to continue to improve compliance. This is a recommendation for improvement in FY2020. In addition to the above, the FY2019 program evaluation included a review of the post-construction ordinances for the Mecklenburg County Phase II jurisdictions. These ordinances are supported by an Administrative Manual. In FY2019, the ordinances and Administrative Manual were determined to be effective; therefore, no changes were made. As part of the overall program evaluation, recommendations for improvement have been made as described in Section 7.3 below. These recommendation will be implemented in FY2020 through the execution of the Work Plan. Table 16: Summary of FY2019 BMP Inspections Jurisdiction # Inspections/ Follow Up Insp.

Increase the number of non-erosion control BMP inspectors, using additional resources to off-set the loss of the Sr. Environmental Specialist position. 2. Increase the number of educational materials given out by incorporating accountability measures to ensure that maintenance information is being given out to the public. 3. Continue training the Town of Huntersville staff on BMP installation inspections. 4. Develop and implement a process/plan to increase BMP compliance, including at a minimum increased follow up inspections when noncompliance is observed. 5. Ensure that all co-permittees have Operation and Maintenance Programs for municipally- owned or maintained structural stormwater controls installed for compliance with the post-construction ordinances. The O&M Programs should include a written Maintenance Plan as required by the ordinance that specifies the frequency of inspections and routine maintenance requirements. Ensure that co-permittees are documenting inspection and maintenance activities performed in accordance with the schedule specified in the Maintenance Plan. Be aware that Richard Farmer with the Water Quality Program is ensuring that the County facilities are doing the above for their structural storm water controls. Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 34 Section 8: Pollution Prevention/Good Housekeeping for Municipal Operations CMSWS has developed and implemented a Pollution Prevention/Good Housekeeping Program for municipal facilities and operations. The goal of the Pollution Prevention/Good Housekeeping Program is to reduce pollutants in storm water runoff from municipal operations. 8.1 Implementation Status for FY2019 Table 19 describes the BMPs identified in the Storm Water Plan for the Pollution Prevention/ Good Housekeeping Program and the specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals for the BMPs specified in the plan have been fulfilled. Table 19: BMP Summary Table for the Pollution Prevention/Good Housekeeping Program BMP Description Implementation Actions Goal Met Yes No Implement Employee Training Program (PP-1) During FY2019, a total of 660 municipal operations’ staff from the County, CMS, CPCC, and the six (6) Towns completed the municipal training program. Table 20 below summarizes the training completed. The training focused on informing staff of the techniques for identifying, eliminating, and reducing pollution sources at their facilities and around the community. Pollution prevention and good housekeeping training materials were developed using an executable program (Articulate) that allows PowerPoint slides to be combined with pollution prevention video clips to create one presentation module. Trainings were conducted in small group settings to facilitate discussions on pollution issues at each facility. All trainings included the review of Storm Water Pollution Prevention Plans (SWPPPs), Spill Response and Clean-up Plans, and storm drainage systems. Videos produced by Excal Visual were included in the module focusing on work typically performed at different facility types (fleet maintenance, land disturbance, parks and recreation, solid waste, streets and drainage, and general municipal jobs). The video identifies activities at these facilities that can negatively impact surface water and demonstrates suggested prevention techniques. At the end of the training, the participates reviewed the information provided during a question and answer session. X Conduct Inspections of Municipal Operations (PP-2) Municipal inspection procedures and inspection forms were reviewed at the beginning of FY2019 and no significant changes were made. On July 26, 2018, CMSWS staff received training on all Phase II municipal inspections. Training included a review of inspection protocols, reports, and deadlines. Based on findings from FY2018 and previous years, common problems were identified and inspector s were instructed to provide guidance to facility managers for resolving them. Emphasis was placed on updating Storm Water Pollution Prevention Plans (SWPPPs) for Phase II municipal facilities and reminding facility managers to complete their assignments over the course of the year. During FY2019, CMSWS staff inspected 60 municipal facilities as follows; 17 for Mecklenburg County, 6 for the Towns, 4 for Central Piedmont Community College (CPCC), and 33 for Charlotte Mecklenburg Schools (CMS). Based on inspection findings in recent years, several areas for improvement were emphasized during the FY2019 inspections, including proper cleanup of petroleum spills, dumpster and trash compactor maintenance, record keeping for compliance with the Phase II stormwater permit, and SWPPP implementation. Five (5) deficiencies were observed at County and Town municipal facilities, which is a decrease from twelve (12) deficiencies observed in FY2018. Three (3) deficiencies were for failure to comply with the SWPPP. Other deficiencies included soil and mulch contamination from a diesel fuel above ground storage tank and a diesel discharge at a fueling island. No repeat X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 35 BMP Description Implementation Actions Goal Met Yes No problems were noted. All SWPPPs were reviewed and updated by CMSWS staff to reflect any changes in the previous year and updated copies were sent to facility managers. The four (4) CPCC campuses in Mecklenburg County inspected in FY2019 include Central, Cato, Harper, and Merancas. Areas of emphasis for FY2019 inspections at CPCC facilities included erosion control and SWPPP implementation, specifically semi-annual self-inspections. Inspectors observed four (4) deficiencies at CPCC facilities. This is a decrease from five (5) deficiencies observed in FY2018. All four (4) campuses had failed to meet the SWPPP requirement of performing annual non storm water discharge evaluations. Improvement in performing the semiannual self-inspections was realized. Ten (10) other minor issues were observed by inspectors, including accumulated sediment in an outfall, BMP maintenance, self-inspection documentation, compromised waste containers, minor wash water discharge, employee training records and erosion control problems at construction projects. No follow up inspections were required for CPCC facilities. SWPPPs were reviewed and updated by CMSWS staff and sent to Zack Harris, Grounds and Site Coordinator for CPCC Facilities Services. Inspections were conducted at 33 CMS facilities. Of these facilities, eight (8) have SWPPPs and are inspected annually. CMS facilities that do not maintain SWPPPs are inspected approximately every five (5) years. Areas of emphasis for inspections at CMS facilities wash water discharge and other illicit discharges. Three (3) deficiencies were observed during CMS facility inspections, a slight increase from the two (2) deficiencies observed in FY2018. All the deficiencies were for illicit discharges. One was due to significant oil staining and oil dry material located on the ground adjacent to a structural canopy. The second involved spilled chemicals, antifreeze and used oil behind a student auto shop. The third involved diesel saturated oil-absorbent material and gravel and leaking fill ports at above ground storage tanks. All contaminated soil was removed and properly disposed of by an environmental cleanup contractor. SWPPP updates at CMS facilities (where required) are completed annually by Mr. Jeff Mitchell, Environmental Health and Safety Specialist for CMS. Inspectors did not note any problems with the SWPPPs at CMS facilities. All observed deficiencies described above for the County, Towns, CMS, and CPPC (excluding those associated with SWPPP requirements) were satisfactorily corrected. Maintain and Update Spill Response Procedures (PP-3) During FY2019, spill response procedures for municipal operations and facilities were reviewed and updated as necessary as a component of the 60 municipal inspections completed under PP-2 above. X Maintain & Implement an Operation & Maintenance Program for Municipally Owned & Maintained Facilities (PP-4) During FY2019, the Operation and Maintenance (O&M) programs contained in Storm Water Pollution Prevention Plans (SWPPPs) were evaluated and updated as necessary as a component of the 60 municipal inspections completed under PP-2 above. During FY2019, an evaluation was also completed of the O&M programs for municipally-owned or maintained structural stormwater controls installed for compliance with the post-construction ordinances adopted by the Phase II jurisdictions as a component of BMP inspections described in PC-2 above. X Maintain and Update an Inventory During FY2019, CMSWS utilized the procedures described in the Storm Water Quality Program Plan to update the inventory of municipal operations and facilities for the purpose of ensuring the identification of all operations and facilities that have X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 36 BMP Description Implementation Actions Goal Met Yes No of Municipal Operations (PP-5) a significant potential for generating polluted storm water runoff so that plans can be developed and implemented for eliminating or reducing these pollutants to protect downstream water quality. As a result, four new parcels were added to the inventory in FY2019 as follows: one for Charlotte-Mecklenburg Schools, one for CPCC, and two for the Town of Huntersville. East language Academy (CMS) was added to the FY20 inspection list. The two new locations in Huntersville were inspected and no significant potential for stormwater pollution was observed. One CPCC facility was inspected and no significant potential for stormwater pollution was observed. Two facilities belonging to Mecklenburg County Parks and Recreation were observed to have not been previously inspected in the past. These facilities, McDowell Creek Nature Preserve Maintenance Compound and Latta Nature Preserve Maintenance Compound were added to the PP-2 inspection list. Develop and Implement BMPS for Streets Roads and Parking Lots (PP-6) BMPs were developed and implemented effective November 11, 2013. During FY2019, co-permittees successfully implemented these BMPs for their respective jurisdictions/entities and provided data to CMSWS for completion of an evaluation that revealed BMPs continue to be effective at reducing pollutants in storm water runoff. The results of this evaluation are described in PP-9 below. The table below summarizes the streets, roads and parking lots cleaned by co-permittees during FY2019. Jurisdiction # Cleaned Lbs.

CMSWS evaluated these BMPs and determined them to be effective at reducing pollutants in storm water runoff as a component of the 57 municipal inspections completed under PP-2 above. X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 37 BMP Description Implementation Actions Goal Met Yes No from Vehicle & Equipment Cleaning Areas (PP-8) Evaluate Effectiveness of Pollution Prevention/ Good Housekeeping Program (PP-9) During FY2018, an evaluation was completed of the Pollution Prevention and Good Housekeeping Program revealing that the program components and BMPs specified in the Storm Water Plan are performing effectively and efficiently at achieving program goals and that they meet or exceed permit requirements. Provided below is a report of the status of the program’s attainment of the specific measures of success contained in the Storm Water Plan. • Documentation of Storm Water Program Activities: For the FY2019 program assessment, an evaluation of the Cityworks database has revealed that CMSWS staff effectively documented the completion of Work Plan activities that demonstrate achievement of each of the measurable goals for the BMPs associated with this program. • Improved Compliance: The indicator of success is a decrease in the ratio of the number of deficiencies observed at municipal facilities to inspections conducted compared to the previous fiscal year. In FY2019, the ratio was 0.200 based on 12 deficiencies detected to 60 inspections conducted. This represents a decrease in noncompliance compared to FY2018 and the other five (5) previous fiscal years except FY2017 that had the lowest ratio recorded at 0.151 (see Figure 6). The FY2019 ratio indicates a measure of success, but additional work is needed to continue to improve compliance. This is a recommendation for improvement in FY2020. An issue observed during an inspection that could negatively impact water quality or result in a permit violation is considered a “deficiency.” During FY2019, a total of 12 deficiencies were observed. This indicates that the improvements implemented in FY2019 helped to reduce the number of deficiencies. The reduction was also due, in part, to the elimination of the qualitative monitoring component of the SWPPPs. Deficiencies not related to the implementation of the SWPPP were related to issues that might impact downstream water quality such as spills and /or leaks. These deficiencies were resolved quickly and documented by follow up inspections. During FY2019, a total of 123 “recommendations” for improvement, which do not represent potential water quality problems or permit violations, resulted from facili ty inspections in addition to the 12 deficiencies for a total of 135 findings, which are described in Table 21 for the past 12 years. During FY2019, the majority of findings fell into one (1) of three (3) categories, including stormwater system and BMPs, erosion, and waste storage/disposal areas. In total, these categories accounted for 71 findings or 52.6% of total findings. As in previous years, overgrown vegetation, trash accumulation, and sedimentation were common problems associated with unmaintained BMPs. Erosion was observed at various types of facilities and was usually associated with construction activities or high- traffic pedestrian areas. Issues at waste storage/disposal areas were observed at several facilities and were usually associated with dumpster wear, such as broken/ missing lids and corrosion. Other relatively common issues were associated with material storage areas (11 findings, or 8.2%), vehicle/equipment areas (11 findings, or 8.2%), and spill response equipment (12 findings, or 8.9%). Most issues noted were minor spills and leaks of oil and other fluids that were not properly cleaned up. CMSWS inspectors recommended that all municipal facilities with the potential to pollute surface waters should maintain spill kits in the appropriate areas. During training for FY2020, emphasis will be placed on educating facility managers about preventing common problems that were observed during FY2019. Areas of emphasis will include erosion control (particularly at construction sites), prope r use X Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 38 BMP Description Implementation Actions Goal Met Yes No and disposal of absorbent materials, use and maintenance of trash dumpsters, spill prevention during fueling operations, and maintenance of structural stormwater BMPs. Photos of housekeeping issues and potential pollution sources observed during inspections will be used for training presentations in FY2020. The program evaluation also included an annual assessment of the effectiveness of the BMPs described in the Storm Water Plan that are currently in use by Mecklenburg County’s Phase II jurisdictions to reduce pollutants from municipally owned streets, roads, parking lots, catch basins, and storm water convey ance systems. This evaluation was based on FY2019 data received from the co-permittees regarding costs and the estimated quantities of pollutants removed as described in the table below. BMPs Lbs. Removed Cost Cost/Lb. Street Sweeping 921,000 $45,3250 $0.49 Parking Lot Cleaning 27,870 $15,300 $0.55 Conveyance Systems Cleaning 84,400 $124700 $1.48 TOTALS 1,033,270 $593,250 $0.57 Based on a report produced by R.C. Sutherland in 2013 entitled Clean Streets Mean Clean Streams, an acceptable pollutant removal range is $3 to $5 per pound. The cost ranges reported by the co-permittees were significantly less; therefore, it is determined that these BMPs are effective at removing pollutants and no changes are proposed in FY2019. As part of the overall evaluation of the Pollution Prevention and Good Housekeeping Program, recommendations for improvement have been made as described in Section 8.3 below. These recommendations will be implemented in FY2020 through the execution of the Work Plan.

Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 41 8.3 Improvements Identified for Implementation in FY2020 The following improvements in the Pollution Prevention/Good Housekeeping Program have been identified for implementation in FY2020 to improve program effectiveness: 1. Enhance efforts to ensure Phase II municipal operations and facilities are complying with NPDES storm water permit requirements by emphasizing the importance of ensuring compliance prior to the State audit in 2021. 2. Ensure that all County facilities, including Park & Recreation and Asset & Facility Management with the County, have Operation and Maintenance Programs for municipally-owned or maintained structural stormwater controls installed for compliance with the post-construction ordinances. The O&M Programs should include a written Maintenance Plan as required by the ordinance that specifies the frequency of inspections and routine maintenance requirements. Ensure that County facilities are documenting inspection and maintenance activities performed in accordance with the schedule specified in the Maintenance Plan. Be aware that Corey Priddy with the Permitting & Compliance Program is ensuring that the other co-permittees are doing the above for their structural storm water controls. Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 42 Section 9: Total Maximum Daily Loads (TMDLs) CMSWS has developed and implemented a program for addressing non-point source pollutant loading associated with the Total Maximum Daily Loads (TMDLs) approved by EPA for the receiving waters of the Phase II MS4 storm water discharges and/or waters downstream of these discharges. The goal of the TMDL Program is to reduce levels of the pollutant(s) of concern to the maximum extent practicable in accordance with approved Waste Load Allocation (WLAs) assigned to storm water in the approved TMDL. 9.1 Implementation Status for FY2019 Table 23 describes the BMPs identified in the Storm Water Plan for the TMDL Program and the specific actions completed between July 1, 2018 and June 30, 2019 (FY2019) for implementation of these BMPs as well as whether the measurable goals for the BMPs specified in the plan have been fulfilled. Table 23: BMP Summary Table for the TMDL Program BMP Description Implementation Actions Goal Met Yes No Evaluate Impaired Waters (IW-1) In June 2019, the State finalized its 2018 303(d) list and integrated 305(b) and 303(d) reports. A review of these reports revealed 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. In addition, a review of the reports revealed that the legacy listings for metals on Little Sugar (below Archdale), Sugar, Irwin, and Mallard (from source to Stoney) were removed and the new criteria for dissolved metals was indicated as being met. Mallard Creek was placed on Category 5 for exceeding the criteria for Turbidity as a result of CMSWS’s data submittal. A new TMDL may be triggered from this new listing. The City and not the County will be responsible for compliance with this new TMDL. No new TMDLs have been developed for Mecklenburg County since 2014. The 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 watershed lies within Phase II, Mecklenburg County will serve as the lead. Table 24 identifies the receiving waters for MS4 discharges in Mecklenburg County that have a TMDL approved by EPA as well as the lead organization for compliance with TMDL requirements based on the above criteria. Figure 7 shows the locations of these receiving waters in relation to the Phase I and Phase II jurisdictions in Mecklenburg County. The lead jurisdiction as identified in Table 24 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 in the implementation of compliance efforts. X Develop and Implement Structural and/or Non- All Water Quality Recovery Plans have been developed and implemented for those watersheds with TMDLs that are the responsibility of Mecklenburg County as described in Table 24 below. These Plans are incorporated into Section 9 of the Storm Water Plan.

Assess, Report and Modify WQRPs (IW-4) An evaluation was completed of the effectiveness of the TMDL Program as described in the latest version of the Storm Water Plan. The TMDL annual assessment is included as Attachment 2 of this report. This assessment includes additional activities to be performed in FY2020 as described below. These additional activities have been incorporated into the Water Quality Recovery Plan located in Section 9 of the Storm Water Plan. They have also been incorporated into the FY2020 Work Plan for implementation.

Routine fixed interval monitoring will continue to be performed monthly at MY-9 on Goose Creek at Stevens Mill Road, MY-14 on Duck Creek at Tara Oaks Lane, and at MY1B located upstream of the Rocky River TMDL watershed. Monthly samples will be analyzed for 16 parameters including fecal coliform, E. Coli, and Enterococcus bacteria. Exceedances of established water quality watch and action levels will be identified and Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 46 follow up actions conducted as necessary for the identification and elimination of pollution sources. 2. By June 30, 2020, 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. 3. By June 30, 2020, 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. In November 2019, design and permitting will be completed for the restoration of a 2 mile section of the Rocky River. Currently, the Rocky River is severely eroded by storm water flows that eat away at the stream banks. The restoration project will stabilize the stream banks to reduce erosion and improve water quality in the creek. 5. By May 2020, construction will be completed on the restoration of a 2.3 miles section of Stevens Creek in the Goose Creek TMDL watershed. Currently, Stevens Creek is severely eroded by storm water flows that eat away at the stream banks. The restoration project will stabilize the stream banks to reduce erosion and improve water quality in the creek. Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 47 Section 10: Program Assessment During FY2019, the permittee has satisfactorily implemented the BMPs and fulfilled the measurable goals specified in Storm Water Permit No. NCS000395 in accordance with the Storm Water Plan as described in the previous sections. The BMPs, measurable goals and activities described in the Storm Water Plan will continue to be implemented in FY2020 along with the program enhancements and modifications described in Sections 11 and 12, respectively. The other provisions of the Permit have also been satisfactorily fulfilled; therefore, compliance with the Permit has been achieved. The permittee further finds that the implementation of the Storm Water Plan as well as the individual BMPs contained in the Plan has resulted in satisfactory compliance with seven (7) of the eight (8) identified measures of success as indicated in Table 25. The only measure of success not met in FY2019 was increasing the extent of exposure for the Public Education and Outreach Program. This was due to very little media coverage for several months during FY2019 while a new media strategy was being developed. The new media strategy will ultimately result in significant improvements in our extent of exposure going forward and the drop in exposure from FY2018 was only 3.1%, so the benefit far outweighs the cost.

Annual Report for July 1, 2018 through June 30, 2019 - Phase II MS4 Permit No. NCS000395 54 Attachment 1: Evaluation of the Effectiveness of the Post-Construction Site Runoff Control Program 1 Evaluation of Post-Construction Site Runoff Control Program September 27, 2019 The purpose of this document is to provide a written assessment of the effectiveness of the Post- Construction Runoff Control Program at fulfilling Phase II Permit requirements for addressing the negative water quality impacts associated with storm water runoff from new development and redevelopment projects in Mecklenburg County’s Phase II jurisdictions. Effectiveness of Storm Water Quality Management Program Plan This section includes an evaluation of the effectiveness of the BMPs for the Post-Construction Site Runoff Control Program as described in the Storm Water Quality Management Program Plan at complying with Phase II Permit requirements. This Plan is considered by the State as part of Mecklenburg County’s Phase II Permit; therefore, it is essential that all components of the Plan are implemented and effectively documented. The purpose of this evaluation is to ensure that the Plan is effective at complying with the Permit requirements and to ensure it was fully implemented in FY2019. Table 1 includes a description of the BMPs and Measurable Goals included in the Plan as well as the Cityworks Activity Report numbers that describe the activities completed for these Measurable Goals and whether the Goals were met. Following this table is an explanation as to how these Goals were met.

Include in this assessment a review of written policies and procedures. 46551 YES PC-1 Implementation of Post-Construction Storm Water Ordinances Effective June 30, 2007, seven (7) post-construction ordinances were adopted in Mecklenburg County to ensure compliance with the Phase II Permit requirements, including an ordinance for each applicable jurisdiction as follows: 1. Town of Cornelius 2. Town of Davidson 3. Town of Huntersville 4. Town of Matthews 5. Town of Mint Hill 6. Town of Pineville 7. Mecklenburg County The ordinances adopted by the Towns are applicable to their corporate limits and extra-territorial jurisdictions (ETJ). Mecklenburg County’s ordinance is applicable in the one (1) square mile area south of Pineville that is outside that Town’s ETJ (see Attachment 1). Staff with Charlotte- Mecklenburg Storm Water Services (CMSWS) administer these seven (7) ordinances for compliance with Phase II Permit requirements. During FY2019, this involved 19,888 staff hours at an estimated cost of $1,702,454.82 to successfully fulfill the 13 activities listed below that are included in Section 7.3 of the Storm Water Plan to ensure compliance with ordinance requirements. During FY2019, a total of 72 new projects were permitted in the Phase II jurisdictions under the Post-Construction Site Runoff Control Program with a total of 789.7 acres disturbed. There were also a total of 13 ordinance interpretations completed by the Storm Water Administrator during FY2019. Table 2 breaks down the hours and costs by individual ordinance compliance 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. 3 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 structural storm water control measures installed for compliance with post-construction ordinance requirements. 10. Ensuring that mechanisms are in place, such as approved as-builts, bonds, etc., to guarantee that projects will be maintained consistent with approved plans in compliance with post-construction 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 each structural BMP has a qualified professional perform annual inspections and maintains records of these inspections. 12. Conducting site inspections of structural storm water 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.

The training was held jointly with the City of Charlotte and lasted approximately six (6) hours. The training also included a history of Mecklenburg County’s water resources and information regarding compliance with the water quality buffer requirements. 5 PC-5 Evaluate Effectiveness of Post-Construction Program In September 2019, an evaluation was completed of the of the Post-Construction Site Runoff Control Program that included an assessment of all ordinances and supporting policies, procedures and guidelines. The successful completion by staff of the 13 compliance activities listed on pages 2 and 3 above was a component of this evaluation. These activities are contained in Section 7.3 of the Storm Water Plan. A review of these activities revealed that they satisfactorily address all the requirements for compliance with the Post-Construction Site Runoff Control Program identified in Section F of Permit No. NCS000395. Therefore, program activities for FY2019 and the Storm Water Plan are determined to be in compliance with Permit requirements. The Storm Water Plan contains additional information regarding measures to be undertaken for compliance with Permit requirements all of which were successfully completed in FY2019. As a result of the FY2019 program assessment, one area was identified and successfully addressed for improvement of Post-Construction Ordinance compliance efforts in the Town of Mint Hill resulting in significant improvement in how built-upon area (BUA) is tracked and regulated. This was accomplished on June 27, 2019 when Town zoning staff agreed to review and verify the correctness of BUA delineations on plats and surveys prior to releasing holds on Certificates of Occupancy. No ordinances changes resulted from this assessment and there were no changes to the Administrative or BMP Design Manuals. The FY2019 assessment also included an evaluation of the Measures of Success contained in the Storm Water Plan as described below. • Documentation of Storm Water 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 Cityworks. For the FY2019 program assessment, an evaluation of the Cityworks database has revealed that CMSWS staff effectively documented the completion of Work Plan activities that demonstrate achievement of each of the measurable goals for the BMPs associated with this program. The log numbers for the Activity Reports that provide this documentation are provided in Table 1 above, with the exception of BMP inspections, which are documented on individual Inspection Reports and not on a single Activity Report in Cityworks. • Improved 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 the ratio of the number of BMPs not in compliance to BMP inspections conducted with a decrease indicating a measure of success at improving compliance, which is a goal of the program. For FY2019, the ratio was 0.686 based on 409 noncompliant BMPs to 596 inspections conducted. This represents a decrease in noncompliance from a ratio of 0.813 in FY2018; however, it represents an increase compared to the other five (5) previous fiscal years (see Figure 5). This indicates a slight measure of success, but 6 additional work is needed to continue to improve compliance. This is a recommendation for improvement in FY2020. Figure 1: % Noncompliant BMPs Progress Toward Implementation of Improvements Identified in the FY2018 Annual Assessment Table 4 below identifies the improvements identified for implementation in FY2019 as a result of the FY2018 annual assessment. However, due to the circumstances described in the table these improvements were not implemented.

Several of the TMDL watersheds in Mecklenburg County span both Phase I and Phase II jurisdictions. All Phase I and Phase II TMDL compliance efforts are administered by Charlotte- Mecklenburg Storm Water Services (CMSWS), which includes both City of Charlotte (City) and Mecklenburg County (County) programs. The City’s program is responsible for compliance with its Phase I storm water permit and Mecklenburg County’s program is responsible for Phase II permit compliance for the County, Charlotte-Mecklenburg Schools, Central Piedmont Community College and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill, and Pineville. To ensure effective coordination, the City and County have agreed that the City 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 watershed lies within Phase II, the 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 in the implementation of compliance efforts. Table 1 indicates the lead jurisdiction for all the approved TMDLs in Charlotte-Mecklenburg. In June 2019, the State finalized its 2018 303(d) list and integrated 305(b) and 303(d) reports. A review of these reports revealed 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. In addition, a review of the reports revealed that the legacy listings for metals on Little Sugar (below Archdale), Sugar, Irwin, and Mallard (from source to Stoney) were removed and the new criteria for dissolved metals was indicated as being met. Mallard Creek was placed on Category 5 for exceeding the criteria for Turbidity as a result of CMSWS’s data submittal. A new TMDL may be triggered from this new listing. The City and not the County will be responsible for compliance with this new TMDL. No new TMDLs have been developed for Mecklenburg County since 2014; therefore, all Mecklenburg County TMDLs have been in effect in excess of 36 months. Based on the requirements contained in Section H of NPDES Permit Number NCS000395, the following must be completed for compliance with the permit requirements for the TMDL watersheds: •Within 12 months of the final approval of a TMDL, the permittee’s annual reports shall include a description of existing programs, controls, partnerships, projects, and strategies (herein referred to as BMPs) to address impaired waters and a brief explanation as to how these BMPs function to restore water quality. •Within 24 months of the final approval of a TMDL, the permittee’s annual reports shall include an assessment of whether additional BMPs are necessary to address impaired waters and a brief explanation as to how these BMPs function to restore water quality. •Within 36 months of the final approval of a TMDL, the permittee’s annual reports shall include a description of additional TMDL compliance activities expected to occur, including a schedule for implementation. 2 The purpose of the annual report contained herein is to describe how the above described permit requirements have been satisfied for the approved TMDLs applicable to Mecklenburg County’s Phase II jurisdictions as described in Table 1. Figure 1 shows the locations of these receiving waters in relation to the Phase I and Phase II jurisdictions in Mecklenburg County. Several of the TMDL watersheds include both Phase I and Phase II jurisdictions and CMSWS performs the activities for compliance with TMDLs countywide for all jurisdictions; therefore, where data is available the tables below include information regarding TMDL compliance activities in both the Phase I and Phase II jurisdictions although Mecklenburg County’s responsibility is only for Phase II as described above.

Tables 3 through 18 describe the activities completed in FY2019 for compliance with TMDLs. Where applicable, compliance activities are described for both the Phase I and Phase II jurisdictions for informational purposes since several of the TMDL watersheds include both jurisdictions; however, Mecklenburg County is only responsible for Phase II Permit compliance for the TMDLs developed for Goose Creek, Rocky River and Lake Wylie. Tables 3 through 18 also include compliance activities performed in the McDowell Creek watershed where applicable even though a watershed management plan and not a TMDL applies (Category 4B). 2.1 BMPs and Associated Measurable Goals During FY2019, all the BMPs and measurable goals identified in Phase II Permit NCS000395 and the associated SWQMPP were effectively fulfilled as described in Table 2. The table also provides the Activity Report number from the County’s Cityworks database that includes documentation of the work completed for each BMP. The subsections following Table 2 describe the existing programs, controls, partnerships, projects, and strategies to address impaired waters (herein referred to as BMPs) and a brief explanation as to how these BMPs address impaired waters. These subsections also describe the specific activities completed in FY2019 through the implementation of these BMPs and whether they will be continued in FY2020 based on an assessment of their effectiveness. Section 3 provides a further assessment of current BMP effectiveness based on an analysis of applicable monitoring data. Section 4 provides a description of additional BMPs implemented in FY2019, as well as those planned for implementation in FY2020 along with an implementation timeline, and a brief explanation as to how these additional BMPs will address impaired waters.

X X X X X Rusty Rozzelle (Program Manager) YES 46187 2.2 Description of Existing BMPs and Their Effectiveness The primary pollutants of concern for the TMDL watersheds where Mecklenburg County is the lead, including Goose Creek, Rocky River and Lake Wylie, are fecal coliform bacteria and chlorophyll-a (see Table 1). CMSWS has reviewed existing BMPs to address impaired waters and has identified those described in the following subsections as suitable for best addressing the TMDL pollutants of concern and will therefore be continued in FY2020. Details regarding BMP implementation are provided in the SWQMPP. 2.2.1 Public Education & Outreach (Section 3 of SWQMPP) 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. During FY2019, these BMPs were effectively implemented in the Phase I and Phase II jurisdictions in Mecklenburg County. 1. Utility Bill Inserts 2. Brochures, Environmental Notices and Newsletters 3.

Storm Water Helpline During FY2019, the following specific public education and outreach activities were completed by CMSWS in the Phase I and Phase II jurisdictions that will reduce discharges of pollutants of concern in the TMDL watersheds. The following handouts/brochures/pamphlets/environmental notices were distributed by CMSWS staff during service requests, inspections, etc. Handouts are also available to the public on the CMSWS website under the “Surface Water Quality” tab, click on “Pollution Prevention.” • A Guide to Used Oil Recycling • Scoop the Poop (proper handling of animal waste) • Only Rain Goes Down The Storm Drain – The Citizen’s Guide to Pollution Prevention • Volunteer Opportunities • A Brief Look at Charlotte-Mecklenburg Storm Water Services – Your Storm Water Fees at Work • Grease Free (proper disposal of grease from Charlotte-Mecklenburg Utilities) • Household Hazardous Waste – What do you do with left over chemicals • Environmental Notices for Homeowners– Disposal into the storm drain is against the law (available in English, Spanish, Chinese, Vietnamese, and Korean) • Environmental Notices for Businesses– Disposal into the storm drain is against the law (available in English, Spanish, Chinese, Vietnamese, and Korean) • Water Watchers door hanger • Household Hazardous Waste slider • Dispose of Leaves Properly postcard • Water Quality Buffers postcard • When Surface Waters Turn Colors (Pollen, Tannin, Iron Bacteria) • Clean Boating Practices • Non-Structural Best Management Practices Handout o Mobile Detailer o Landscapers o Painters o Contractors o Carpet Cleaners o Vehicle Service o Food Service o Multi-family o Stone Cutting & Fabrication Industry o Concrete Industry o Commercial Property Management o Asphalt Sealing o Swimming Pool & Spa Industry 7 o Horizontal Directional Drilling • Structural Best Management Practices Handout o Dry Detention o Rain Garden o Sand Filter o Storm water Wetland o Wet Pond During FY2019, educational newsletters were developed and disseminated to the Phase I and Phase II jurisdictions covering the targeted pollutants described above. These newsletters focused on the actions the public should take to reduce pollution, including participating in volunteer programs, and reporting suspected pollution problems. The @StormWaterCM social media accounts (Facebook, Twitter & Instagram) were used as the main method to help disseminate messages to the Towns. Phase I and Phase II social media contacts were responsible for sharing messages on the Towns’ or institutions’ social media accounts. Due to not using social media, Barbara Monticello with the Town of Pineville was emailed messages to be included in the local town mailer. In order to address compliance with the Goose Creek TMDL, additional social media messages were created for the Town of Mint Hill that focused on reducing bacteria levels in surface waters. Social media messages were also used to promote the sale of tree seedlings and rain barrels by the Mecklenburg County Soil and Water Conservation District. During FY2019, age specific educational information was developed and distributed in schools. In October 2019, science teachers were emailed information on the water quality educational programs being offered. As a result, 21 school presentations were given in the Phase II jurisdiction to 516 students as follows: • 9/28/18: Catawba Stem Festival, 5th grade, 3 classes, 94 students, Flood Plain Model • 3/8/19: Phoenix Montessori Academy, K-8th, 3 classes, 62 students, Journey of a Raindrop & Enviroscape • 4/12/2019: North Mecklenburg High School, 9 grade, 15 classes, 360 students, Presentation and Video on Careers School presentations were also performed in the Phase I jurisdiction. Table 3 describes the school presentations conducted in the Phase I and Phase II TMDL jurisdictions in Charlotte- Mecklenburg during FY2019.

During FY2019, a special outreach campaign focusing on reducing bacteria level in our streams was again utilized. The campaign was called “Scoop the Poop.” Scoop the Poop included Social Media Posts and videos, a website banner and additional website information including a story map, vehicle magnets, and a flagging campaign where at select locations piles of animal waste not picked up by owners were “flagged” with a sign that identified harmful bacteria and parasites that could be present in the waste. During FY2019, informational pages covering a wide variety of topics were maintained on the Storm Water Services website for Phase I and Phase II, including current water quality conditions, storm water pollutants and ways to minimize them, reporting pollution, volunteering, municipal storm water projects/activities, etc. These web pages also provide a means to register for various volunteer initiatives. The targeted pollutants on the pollution prevention pages include: bacteria and pet waste, turbidity, sediment, phosphorus, nitrogen, organics, fertilizers, pesticides, yard waste, surfactants, hydrocarbons, pH, and toxic compounds. The targeted audiences include residential, commercial and institutional. The general messages promoted on the web pages are street to stream, only rain should go down the storm drain, and be a Water Watcher/Volunteer. The web pages also provide contacts for reporting pollution problems/concerns and submitting questions to staff. During FY2019, Google Analytics showed CMSWS’s web pages had 376,617 page views, which is an increase of 36.66% from the 275,595 page views in FY2018. This increase is attributed to the increase in social posts and all collateral including the website, and with direct links where possible. The pages most often visited were the Floodplains and Maps, the Homepage, and The Big Spring Clean page. For Industrial/ Commercial Education, staff attended and presented at the Regional Stormwater Partnership of the Carolinas meeting on Storm Water Pollution Prevention (SWPP) service requests. Car maintenance BMP posters were distributed during routine inspections and service requests and also at several auto body shops throughout the county.

The campaign included television, radio, online, print, and Out-of-Home ads as well as social media (Facebook, Twitter, Instagram and YouTube). Out-of-Home ads included the 4th Street Garage banner promoting the annual Big Spring Clean and a banner promoting Flood Safety. Print ads included five (5) Utility Bill Inserts (UBIs). UBIs are two-sided and cover storm water related topics such as flooding, living in floodplains, storm water pollution indicators, preventing and reporting storm water pollution, volunteering, etc. During FY2019, UBI messages were mailed to 255,000 customers in Charlotte-Mecklenburg once a month for five (5) months for a total of 1,275,000 contacts. A summary of the 2019 media campaign is provided below. • Number of television advertising spots developed: 2 (Telemundo & TBSC) • Impressions & Reach of television advertising spots: Impressions = 980,715; Reach = 13.5% • Number of radio advertising spots developed: 4 at WFAE; 1 per each campaign • Impressions & Reach of radio advertising spots: Impressions = 84,000; Reach = 11.5% • Number of print advertising spots developed: 2, 4th Street Banners & 1, I-277 Street Banner • Impressions of print advertising spot: Impressions = 265,800 • Number of electronic advertising spots developed: 10+ • Impressions of electronic advertising spots: Impressions = 3,502,153 During FY2019, the BMPs implemented for the Public Education and Outreach Program were evaluated and found to be effective at reducing non-point source pollutant loading to the receiving streams of TMDL watersheds to the maximum extent practicable fulfilling the 11 requirements of the Phase II Permit and SWQMPP. Therefore, these BMPs will continue to be used in FY2020 to comply with TMDL requirements. 2.2.2 Public Involvement and Participation (Section 4 of SWQMPP) The following existing public involvement and participation activities have been identified as suitable for addressing the pollutants of concern in the TMDL watersheds. These BMPs will address impaired waters by involving the public in program development and implementation to reduce the pollutants of concern. During FY2019, these BMPs were effectively implemented in the Phase I and Phase II jurisdictions in Mecklenburg County. 1. Adopt-A-Stream 2. Storm Drain Marking 3. Annual Surface Water Clean Up Event Adopt-A-Stream - During FY2019, 26 groups that included a total of 499 volunteers donated 1,272.25 hours toward the completion of 48 stream cleanups resulting in the removal of 5,912 pounds of trash and debris from 42.57 miles of streams in Mecklenburg County’s Phase II jurisdiction. The breakdown of miles of streams cleaned up by jurisdiction is as follow: • Davidson: 6.6 miles • Huntersville: 10.47 miles • Matthews: 4.43 miles • Mecklenburg County: 25.17 miles • Pineville: 3.42 miles The names of the stream segments cleaned up include: Caldwell Station, Four Mile Creek, Gar Creek, Irvins Creek, Irwin Creek, Lake Davidson, Little Sugar Creek, McAlpine Creek, Ramah Creek, Rocky River West Branch, Stewart Creek, and Torrence Creek. There is a total of 21.24 stream miles adopted in the Phase II jurisdiction. These efforts were completed under the County’s Adopt-A-Stream Program. Additional data is available in the Volunteer Database. Adopt-A-Stream activities are also performed in the Phase I jurisdiction.

Therefore, CMSWS developed a “Thank You” campaign that recognized an overall “Volunteer of the Year” along with recognizing a volunteer from each of our volunteer programs, including Adopt-A-Stream and Storm Drain Marking. As a part of the campaign, car magnets were designed and given out to all volunteers at events. The magnets promote clean water, while also help to increase awareness of our programs. T-shirts were designed for the volunteers of the year with the same advertising strategy in mind. Each volunteer of the year group was the focus of a newsletter that went out to all volunteers. Newsletter recipients were posted on all social media channels. During FY2019, the BMPs implemented for the Public Involvement and Participation Program were evaluated and found to be effective at reducing non-point source pollutant loading to the receiving streams of TMDL watersheds to the maximum extent practicable fulfilling the requirements of the Phase II Permit and SWQMPP. Therefore, these BMPs will continue to be used in FY2020 to comply with TMDL requirements. 2.2.3 Illicit Discharge Detection and Elimination (IDDE) (Section 5 of SWQMPP) The following existing IDDE activities have been identified as suitable for addressing the pollutants of concern in the TMDL watersheds. These BMPs will address impaired waters by 14 identifying and eliminating sources of the pollutants of concern. During FY2019, these BMPs were effectively implemented in the Phase I and Phase II jurisdictions in Mecklenburg County. 1. Storm Sewer System Mapping 2. Responding to Citizen Requests for Service 3.

The identification of pollution sources is accomplished by investigating business corridors and industrial facilities in Mecklenburg County. During FY2019, a total of seventeen (17) storm water outfalls were inspected under IDEP in Phase II and one (1) Notice of Violation was issued. In addition, seven (7) facilities were inspected under IDEP in Phase II during FY2019. All industrial facilities inspected were NPDES permitted. Several of these inspections were conducted in TMDL watersheds. Stream Walks – During FY2019, staff walked approximately 58.62 stream miles in the Phase II jurisdictions, including 51.78 in the Towns and 6.84 miles in the ETJ areas located in the County (see Figure 2). The following miles were assessed within each municipal boundary: 27.10 in Matthews, 22.73 in Mint Hill, 1.86 in Pineville, and 0.08 in Stallings. 157 features were mapped in Matthews, 95 in Mint Hill, 4 in Pineville, 3 in Stallings, and 25 points were mapped in the ETJ. In all, there were 284 points or features recorded, 63 outfalls inspected, 151 new outfalls identified, and 103 fecal coliform samples collected. Seven (7) of these samples resulted in bacteria action level exceedances (>3000 col/100ml). No exceedances above the action level for total phosphorus were detected (0.50 ppm). Two (2) buffer/floodplain disturbances were identified and reported and followed up on. No dry weather flows or pollution sources were observed during FY2019 Phase II stream walk activities. Stream walk activities are also performed in the Phase I jurisdiction. Figure 2 identifies the basins that were walked during FY2019 in the Phase I and Phase II jurisdictions.

At each 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. CMSWS also performs annual monitoring for benthic macroinvertebrates in the Phase I and Phase II jurisdictions at these 33 stream monitoring locations. CMSWS maintains a Continuous Monitoring and Alert Notification Network or CMANN at 32 of the 33 fixed interval monitoring locations shown in Figure 3 that collects data hourly for turbidity, dissolved oxygen, temperature, conductivity, and pH. CMSWS conducts routine lake monitoring at 27 locations on Lake Norman, Mountain Island Lake and Lake Wylie, including seven locations in the TMDL area identified in Figure 1 for Lake Wylie. This monitoring is performed every other month for the following 13 parameters: secchi depth, temperature, dissolved oxygen, conductivity, pH, fecal coliform bacteria, alkalinity, ammonia nitrogen, nitrate + nitrite, total kjeldahl nitrogen, total phosphorus, turbidity, and chlorophyll a. Monitoring for the following 12 parameters is performed twice a year: copper, chromium, lead, zinc, mercury, manganese, arsenic, cadmium, nickel, selenium, aluminum, and iron. All monitoring results that exceed threshold values are referred for follow- up under the Illicit Discharge Detection and Elimination (IDDE) Program. Long term assessment for trends are done on a non-fixed frequency (as-needed). Provided below is an assessment of the data collected for the identified parameters in the three (3) TMDL watersheds where Mecklenburg County is assigned as the lead, which includes the Rocky River and Goose Creek impaired for fecal coliform bacteria and Lake Wylie impaired for chlorophyll-a (see Table 1). 27 Figure 3: Water Quality Monitoring Locations in Mecklenburg County 3.1 Rocky River Fecal Coliform Monitoring and Land Use Evaluation As identified in Table 1, 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 storm water that was approved on September 19, 2002. According the approved NC 2018 305(b) report, the Rocky River is currently not meeting the fecal coliform criteria. Mecklenburg County has been assigned 28 responsibility for 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 continue to evaluate the land use and development within the watershed on an annual basis and if additional storm water 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 19). Between 2017 and 2018 there was a 3.2% increase in residential impervious cover to a total of 15.69 acres. The commercial impervious cover remained unchanged at 0.33 acres for a total amount of impervious cover in the watershed at 16.02 acres. Compared to the total area of the watershed at 747 acres, the amount of imperious cover is at 2.14%, which is an increase of 1.95% since 2011. The number of outfalls is unchanged from 2017 at four (4), which has increased by three (3) outfalls since 2011. To date, changes in the watershed are not significant enough to warrant the establishment of a Monitoring Plan.

According the approved NC 2018 305(b) report, the two (2) TMDL segments of Goose Creek are currently meeting the fecal coliform 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) located where Stevens Mill Road crosses Goose Creek in Union County. In 2018, CMSWS fecal coliform counts at this station ranged from 100 to 10,800 CFU/100 ml, with 11 out of 19 (58%) in compliance (≤400 CFU/100 ml). No pollution sources were identified as a result of the water quality monitoring in the Goose Creek TMDL watershed during FY2018. Table 21 provides a summary of this data from 2014 through 2018.

According the approved NC 2018 305(b) report, the two (2) TMDL segments of Lake Wylie are currently meeting the chlorophyll a 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. All 69 Lake Wylie Chlorophyll-a samples collected by CMSWS in 2018 were below 40 ug/l. Figures 8 and 9 provide a comparison of fecal coliform data indicating improvement over time.

Also for this reason, this document does not include compliance measures for this TMDL. 3.5 Effectiveness of BMPs Based on Data Analysis Based on the above described assessments of data collected in the TMDL watersheds, 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 FY2020. Additional structural and/or non-structural BMPs will be implemented as described in Section 4 to further enhance TMDL compliance. Section 4: Additional BMP Measures As required by Permit No. NCS000395, CMSWS is continuing to evaluate the effectiveness of the existing structural and/or non-structural BMPs described in the previous section and identify and implement additional BMPs as necessary to effectively address impaired waters. The following subsections describe the additional BMPs implemented in FY2019, as well as those planned for implementation in 2019 along with an implementation timeline, and a brief explanation as to how these additional BMPs will address impaired waters. 4.1 Additional BMPs Implemented for the Rocky River TMDL in FY2019 During FY2019, the following additional activities were completed to reduce fecal coliform bacteria levels and enhance water quality in the Rocky River watershed: 1. Monthly water quality monitoring, including sampling for fecal coliform bacteria, continued at site MY1B (West Branch of the Rocky River at River Ford Drive) located upstream of the TMDL watershed in Mecklenburg County. No exceedances of water quality standards were detected . No pollution sources were identified as a result of this monitoring. 2. On December 15, 2018, Health Department records were reviewed and no failed septic systems were identified. 3. On October 24, 2018, the four (4) major outfalls in the Rocky River TMDL watershed in Mecklenburg County were inspected. No dry weather flows or pollution sources were detected. 4. Design plans are under development for the restoration of a section of the Rocky River in the TMDL water in Mecklenburg County. 4.2 Additional BMPs Implemented for the Goose Creek TMDL in FY2019 During FY2019, the following additional activities were completed to reduce fecal coliform bacteria levels and enhance water quality in the Goose Creek watershed: 33 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 analyzed for 16 parameters including fecal coliform, E. Coli, and Enterococcus bacteria. Monitoring results are described in Section 3.2. 2. Beginning on November 1, 2018 and concluding on May 16, 2019, extensive monitoring for fecal coliform bacteria was performed throughout the Goose Creek watershed during stream walk activities. No pollution sources were detected. 3. On December 15, 2018, Health Department records were reviewed and no failed septic systems were identified. 4.3 Additional BMPs to be Implemented in FY2020 During FY2020, the following additional BMPs will be implemented in the Rocky River Goose Creek watersheds to reduce fecal coliform bacteria levels and enhance water quality: 1. Routine fixed interval monitoring will continue to be performed monthly at MY-9 on Goose Creek at Stevens Mill Road, MY-14 on Duck Creek at Tara Oaks Lane, and at MY1B located upstream of the Rocky River TMDL watershed. Monthly samples will be analyzed for 16 parameters including fecal coliform, E. Coli, and Enterococcus bacteria. 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 June 30, 2020, 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. 3. By June 30, 2020, 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. In November 2019, design and permitting will be completed for the restoration of a 2 mile section of the Rocky River. Currently, the Rocky River is severely eroded by storm water flows that eat away at the stream banks. The restoration project will stabilize the stream banks to reduce erosion and improve water quality in the creek. 5. By May 2020, construction will be completed on the restoration of a 2.3 miles section of Stevens Creek in the Goose Creek TMDL watershed. Currently, Stevens Creek is severely eroded by storm water flows that eat away at the stream banks. The restoration project will stabilize the stream banks to reduce erosion and improve water quality in the creek. Section 5: Tracking and Reporting Success 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. 34 Section 6: TMDL Reporting This report fulfills the SWQMPP TMDL reporting requirement by providing a summary of the following: 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.
