This Plan includes information regarding staff training, implementation activities, and recordkeeping regarding specific operation and maintenance activities and responsibilities in a standardized and well -documented manner. Operation and maintenance of the City's MS4 is a requirement of the City's National Pollutant Discharge Elimination System (NPDES) Phase I MS4 Permit and applicable provisions of the Clean Water Act (CWA) to reduce pollutants in stormwater runoff to the maximum extent practicable (MEP). Operation and maintenance of the MS4 is primarily contained within Part II G (Pollution Prevention and Good Housekeeping (PP/GH) for Municipal Operations) of the City's Phase I MS4 permit. This Plan specifically refers to the operation and maintenance of the MS4 while referencing other relevant documents, including standard operating procedures (SOPs), guidance documents, policies, ordinances, and other procedures where appropriate. The municipal separate storm sewer system refers to the combination of features, or infrastructure components, that collect, convey, and/or provide water quality treatment of stormwater runoff within the City of Greensboro MS4 area. This includes all City -owned and City -maintained streets and roadways, parking lots, curbs and gutters, ditches and channels, storm drains and pipes, culverts, post -construction, and other stormwater control measures (SCMs). 5 City of Greensboro MS4 Operation and Maintenance Plan May 5, 2022 2.0 MANAGEMENT AND OPERATION OF GREENSBORO'S MS4 Greensboro's MS4 is operated and maintained by various City departments as a Stormwater Management Utility. The Stormwater Management Utility is one of seven divisions of the City's Water Resources Department, which also includes water supply, water reclamation, customer service, business, engineering, and operations and maintenance. Although the Stormwater Management Division resides within the Water Resources Department, the program itself is much broader and encompasses and/or extends well beyond the boundaries of the Water Resources Department. Several other departments in the City of Greensboro contribute to the operation and maintenance of the MS4. Current departmental responsibilities related to MS4 operation and maintenance, as of the date of this document, are summarized below. Please note that this is not a comprehensive list of departmental responsibilities for MS4 permit implementation; refer to the most recent City of Greensboro Storm Water Management Plan (SWMP) for a complete description of MS4 responsibilities and the MS4 organizational chart (Appendix B). Water Resources Department (WR): NPDES MS4 Discharge Permit administration for Greensboro; stormwater conveyance system inventory and detailed MS4 outfall mapping; SCM evaluations and crediting; SCM inspections and monitoring; field screening and follow-up monitoring activities; industrial monitoring and related activities; industrial inspections and educational efforts; system inspection; special stormwater inspection and enforcement programs; spill response and investigation; water quality inspections and monitoring programs; overall authority (as delegated from City Manager's Office) over the municipal stormwater quality management programs. • City Field Operations Department (FOD): Litter (including floatables) and loose-leaf collection programs; solid waste and recycling collections, street cleaning and sweeping programs; closed drainage infrastructure system routine and remedial maintenance activities; open channel maintenance; environmental compliance, new storm sewer construction. • City Parks and Recreation (P&R) Department: City of Greensboro parks, greenway, cemeteries, athletic facilities, gardens, and utility easement maintenance coordination and programs. • City Fire Department: Spill response program — HAZMAT (HAZardous MATerials) Team, containment of spills; industrial site inspections. • Greensboro Department of Transportation (GDOT): Roadway improvements and street resurfacing. Table 1 identifies the responsible City department(s) and the key personnel for each MS4 component type. 0 City of Greensboro MS4 Operation and Maintenance Plan May 5, 2022 Table 1.

Common pollutants in stormwater runoff include nutrients, sediment, trash, bacteria, and vehicle fluids including oil. MS4 maintenance issues that may indicate potential problems can include structural damage, erosion, corrosion, blockages, debris, sediment accumulation, upland pollutant inputs (e.g., from erosion, spills, poor storage practices, etc.), and undesirable vegetation. Routine maintenance can help identify MS4 operational concerns and required maintenance needs before more serious problems occur and can also be used to identify potential illicit discharges in conjunction with the City's Illicit Discharge Detection and Elimination (IDDE) program. The operation and maintenance of the MS4 consist of a wide range of tasks, activities, and recordkeeping conducted by the organizational units identified in Table 1. In general, operation and maintenance tasks are driven by 1) federal and state laws and regulations, 2) the requirements of the City's NPDES MS4 Phase I MS4 permit, 3) local water quality protection and restoration objectives, 4) general City infrastructure protection goals, and 5) flood prevention and 6) other site specific NCDEQ Industrial Stormwater Permits. Table 2 provides a summary of essential activities conducted by City personnel to operate and maintain the MS4 and its components. Section 3.0 of this document contains detailed operation and maintenance information for specific MS4 components, with references to various City standard operating procedures, policies, and the City of Greensboro Stormwater Management Manual. Detailed Illicit Discharge, Detection, and Elimination (IDDE) actions are outlined within the IDDE standard operating procedures as a separate document. The Storm Water Management Plan (SWMP) outlines additional actions that may not be covered in this Plan as outlined in the NPDES MS4 Phase I permit. 0 City of Greensboro MS4 Operation and Maintenance Plan May 5, 2022 Table 2. Essential Operation and Maintenance Activities for MS4 Components Conduct inspections of City -owned SCMs and facilities as specified in the appropriate SOPs, industrial stormwater permits, or pollution prevention/good housekeeping program. Maintain MS4 system components — streets, roads, parking lots, ditches, channels, pipes, inlets, ponds, etc. Report structural problems, potential blockages, illicit discharges, dumping, spills, or other conditions that may cause flooding or affect water quality. Repair, replace, or otherwise address structural issues, such as damaged headwalls, exposed or misaligned pipe, heavy ditch/channel erosion/scouring, damaged or poorly functioning basin/pond outlets, or other structural problems associated with MS4 components. Remove blockages to storm drain inlets, stormwater pipes, ditches, channels, and other conveyances; report major blockages requiring additional equipment immediately. Address or report standing water causing street or other flooding; assess and report possible emergency conditions. Ensure materials containing potential pollutants are stored properly, reducing the likelihood of entering the City's MS4 system. Remove dirt, litter, waste, dead animals, and other debris from City parking lots, streets, and roads via sweeping and other dry methods wherever possible to prevent pollutants from entering local streams. Stabilize eroded areas contributing sediment to the MS4 by seeding, mulching, or armoring to prevent further erosion. Conduct training for City staff involved with building, operating, or maintaining the MS4. Respond promptly to spills to ensure public safety and containment, cleanup, and proper disposal of all materials. Stabilize eroded areas contributing sediment to the MS4 by seeding, mulching, or armoring to prevent further erosion Conduct training for City staff involved with building, operating, or maintaining the MS4. Identify and address nuisance conditions, such as unwanted or excessive vegetation affecting stormwater flow, animal burrows, or other conditions affecting MS4 operation.
