This SWMP identifies the specific elements and minimum measures that the Town of Morrisville will develop, implement, enforce, evaluate and report to the North Carolina Department of Environmental Quality (NCDEQ) Division of Energy, Minerals and Land Resources (DEMLR) in order to comply with the MS4 Permit number NCS000465, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the Town of Morrisville and located within the corporate limits of the Town of Morrisville. In preparing this SWMP, the Town of Morrisville has evaluated its MS4 and the permit requirements to develop a comprehensive 5-year SWMP that will meet the community's needs, address local water quality issues and provide the minimum measures necessary to comply with the permit. The SWMP will be evaluated and updated annually to ensure that the elements and minimum measures it contains continue to adequately provide for permit compliance and the community's needs. Once the SWMP is approved by NCDEQ, all provisions contained and referenced in this SWMP, along with any approved modifications of the SWMP, arc incorporated by reference into the permit and becoiue enforceable parts of the permit. Any major changes to the approved SWMP will require resubmittal, review and approval by NCDEQ, and may require a new public comment period depending on the nature of the changes.

Signature: Print Name: Martha Paige Title: Town Manager Signed this day of 20 DRAFT NCS000465 SWMP Morrisville June 2021 Page 2 PART 3: MS4 INFORMATION 3.1 Permitted MS4 Area This SWMP applies throughout the corporate limits of the Town of Morrisville, including all regulated activities associated with the discharge of stormwater from the MS4. The map below shows the corporate limits of Town of Morrisville as of the date of this document. DRAFT NCS000465 SWMP Morrisville June 2021 Page 3 3.2 Existing MS4 Mapping Runoff from most of the earlier development (prior to 1999) in the Town flows directly to surface waters without any form of treatment. For developments since implementation of the Town's 1999 stormwater ordinance and first Phase II permit in 2005, runoff flows to various detention systems and other structural Stormwater Control Measures (SCMs) prior to entering the receiving streams. The current MS4 mapping program includes the location of system components (including inlets, outfalls, pipes, and culverts), SCMs, waterbodies, major basins, and subbasins. Pipe Condition, flow direction, and pipe size are also included. This Publicly available information can be found online on the Town of Morrisville Stormwater Map. Mapping of the Town's storm system was updated in 2021. The Town estimates that approximately 99% of the MS4 area is mapped. Table 1: Summary of Current MS4 Mapping Percent of MS4 Area Mapped 99 % No. of Major Outfalls* Mapped 264 total *An outfall is a point where the MS4 discharges from a pipe or other conveyance (e.g. a ditch) directly into surface waters. Major outfalls are required to he mapped to meetpermit requirements. A major outfall is a 36-inch or larger diameter pipe or discharge from a drainage area > 50-acres; and for industrial zoned areas a 12-inch or larger diameter pipe or a drainage area > 2-acres. 3.3 Receiving Waters The Town of Morrisville MS4 is located within the Neuse and Cape Fear River Basins and discharges directly into receiving waters, as listed in Table 2 below. Applicable water quality standards listed below are compiled from the following NCDEQ sources: o Waterbody Classification Map o Impaired Waters and TMDL Map o Most recent NCDEQ Final 303 d List DRAFT NCS000465 SWMP Morrisville June 2021 Page 4 Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / AU Number Water Quality Classification 303(d) Listed Parameter(s) of Interest Cape Fear River Basin (Jordan Lake) Kit Creek 16-41-1-17-2- 0.3 C; NSW N/A Kit Creek 16-41-1-17-2-(0.7) WS-IV; NSW N/A Neuse River Basin Brier Creek 27-33-4 C; NSW PCB (Advisory, FC, NC) Stirru Iron Creek 27-33-4-2 C; NSW N/A Coles Branch 27-33-3 C; NSW N/A Crabtree Creek 27-33-(1) C; NSW Benthos (Nar, AL, FW) C — Class C (fishable/swimmable waters) NSW — Nutrient sensitive water PCB (Advisory, FC, NC) — Polychlorinated biphenyl fish tissue advisory, fish consumption Benthos (Nar, AL, FW) — Narrative standard, aquatic life, fresh waters, poor bioclassification The above Data is from 2020 NC Category 5 Assessments "Draft 303(d) List" and NC Surface Water Classifications Map. From the 2020 303(d) Listing and Delisting Methodology for Benthos: "Narrative criterion: Waters shall be suitable for aquatic life propagation and maintenance of biological integrity. NC uses benthic and fish community data to assess biological integrity. Biological integrity means the ability of an aquatic ecosystem to support and maintain a balanced and indigenous community of organisms having species composition, diversity, population densities and functional organization similar to that of reference conditions" The Town of Morrisville utilizes Public Education and Outreach BMPs #4-7 to provide information on water quality impairments in the Neuse River Basin and PCBs and nitrogen are target pollutants. The Neuse River Subbasin Plan for Crabtree and Brier Creeks and Protecting Water Quality supplement are used to guide BMPs. 3.4 MS4 Interconnection The Town of Morrisville MS4 is interconnected with another regulated MS4 and receives/discharges stormwater into the Town of Cary MS4. The number of interconnections leaving the Town of Morrisville MS4 have not been estimated; however, locations of outfalls within the Town of Morrisville ETJ are on the MS4 map and are part of the IDDE and MS4 inspections. The MS4 also interconnects with the statewide NCDOT MS4 and includes: a. The interconnection is receiving stormwater from the NCDOT MS4. The number of interconnections is unknown. b. The interconnection is discharging stormwater into the NCDOT MS4. The number of interconnections is unknown. DRAFT NCS000465 SWMP Morrisville June 2021 Page 5 c. The Town of Morrisville MS4 mapping does include NCDOT MS4 outfalls. 3.5 Total Maximum Daily Loads (TMDLs) The 'i'MDL(s) listed in Table 3 below have been approved within the MS4 area, as determined by the map and list provided on the NCDEQ Modeling & Assessment Unit web page. The table also indicates whether the approved TMDL has a specific stormwater Waste Load Allocation (WLA) for any watershed directly receiving discharges from the permitted MS4, and whether a Water Quality Recovery Program has been implemented to address the WLA. Table 3: Summary of Approved TMDLs Water Body Name TMDL Pollutant(s) Stormwater Waste Water Quality Recovery of Concern Load Allocation (Y/N) Program /N) Statewide Mercury N N While the Neuse River has a TMDL for nitrogen, the Town of Morrisville discharges to tributaries of the Neuse that do not have TMDLs. The Town of Morrisville utilizes Public Education and Outreach BMPs #4-6 to provide information on nitrogen in the Neuse River Basin. While the Statewide TMDL for mercury does not require any actions by the NPDES stormwater permittee because most mercury in stormwater comes from atmospheric deposition, the Town utilizes BMPs #4-7 to provide information to the public. This SWMP also includes BMPs to implement a Local Neuse Nutrient Management Strategy (Neuse Local Program) for the updated Neuse River Rules, which were adopted in April 2021. 3.6 Endangered and Threatened Species and Critical Habitat Significant populations of threatened or endangered species and/or critical habitat are potentially located within the regulated MS4 urbanized area. Based upon a review of the Endangered and Threatened S ecies and Species of Concern by County for North Carolina Map and Listed species believe to or known to occur in North Carolina map as provided by the U.S. Fish and Wildlife Service, the species listed in Table 4 have the potential to occur within the regulated MS4 urbanized area. Of those species listed, Table 4 summarizes the species that may be significantly impacted by the quality of surface waters within their habitat.

Industrial outfalls are also inspected as part of the Illicit Discharge Detection and Elimination program BMP #17. 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Morrisville as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Morrisville has evaluated residential, charity car washing and street washing for possible significant water quality impacts. DRAFT NCS000465 SWMP Morrisville June 2021 Page 7 Wash water associated with car washing that does not contain detergents or does not discharge directly into the MS4 is considered incidental. However, these types of non-stormwater discharges that do contain detergents have been evaluated by the Town of Morrisville to determine whether they may significantly impact water quality. They were determined to be a possible cause of water quality impacts and will be addressed through Public Education and Outreach BMPs #4-6. Street sweeping in Morrisville utilizes a dry street sweeper and therefore street wash water is not considered a possible water quality impact. The Division has not required that other non-stormwater flows be specifically controlled by the Town of Morrisville. Table 6: Non-Stormwater Discharges Non-Stormwater Discharge Water Quality Impacts Water line and fire hydrant flushing Incidental Landscape irrigation Incidental Diverted stream flows Incidental Rising groundwater Incidental Uncontaminated groundwater infiltration Incidental Uncontaminated pumped groundwater Incidental Uncontaminated potable water sources incidental Foundation drains Incidental Air conditioning condensate Incidental Irrigation waters Incidental Springs Incidental Water from crawls ace pumps Incidental Footing drains Incidental Lawn watering Incidental Residential and charity car washing Possible Flows from riparian habitats and wetlands Incidental Dechlorinated swimming pool discharges Incidental Street wash water Incidental Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources Other than those target pollutants identified below, the Town of Morrisville is not aware of other significant water quality issues within the permitted MS4 area. Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWMP, the likely activities/sources/targeted audiences attributed to each pollutant and identifies the associated SWMP program(s) that address each. In addition, the Town of Morrisville has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

The SPCA requirements include reducing pollutants in stormwater runoff from construction activities that result in land disturbance of greater than or equal to one acre, and includes any construction activity that is part of a larger common plan of development that would disturb one acre or more. The state SPCA Program is either delegated to a city/town, delegated to a county, or implemented by NCDEQ in non -delegated areas.

DRAFT NCS000465 SWMP Morrisville June 2021 Page 25 PART 9: POST -CONSTRUCTION SITE RUNOFF CONTROL PROGRAM This SWMP identifies the minimum elements to develop, implement and enforce a program to address stormwater runoff from new development and redevelopment projects that disturb greater than or equal to one acre, including commercial or industrial projects less than one acre or projects that are part of a larger common plan of development or sale, that are located within the Town of Morrisville and discharge into the MS4. These elements are designed to minimize water quality impacts utilizing a combination of structural Stormwater Control Measures (SCMs) and/or non-structural BMPs appropriate for the community and ensure adequate long-term operation and maintenance of SCMs. This part of the Neuse Local Program identifies the elements being used to develop, implement, and enforce a program to reduce nutrients in stormwater runoff from new development projects and development expansions. These elements meet the requirements set forth in the Neuse Stormwater Rule (15A NCAC 02B .0711). These elements are designed to minimize water quality impacts through a combination of structural SCMs and nutrient offset buy -downs, and to ensure adequate long-term operation and maintenance of SCMs. In accordance with 15A NCAC 02H .0153 and .1017, the Town of Morrisville implements the following State post -construction program requirements, which satisfy the NPDES Phase II MS4 post -construction site runoff control requirements as Qualifying Alternative Programs (QAPs) in the MS4 area(s) where they are implemented.
