REVISION LOG
City of Greensboro MS4 Operation and Maintenance Plan May 5, 2022
1.0 INTRODUCTION
The purpose of this Municipal Separate Storm Sewer System (MS4) Operation and Maintenance Plan
(Plan) is to describe how the City of Greensboro (City) performs and documents activities to operate and
maintain its municipally owned stormwater conveyance system. 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).

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.

2.1 Overview of MS4 Operation and Maintenance Tasks
Because the City's MS4 has the potential to transport stormwater pollutants as runoff flows across
pervious and impervious areas, routine maintenance is essential to ensure that structures are functioning
as designed and to minimize the potential discharge of pollutants to streams, rivers, and lakes in the City
of Greensboro and beyond. 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.

All City -owned SCMs are inspected by Stormwater Management (WR). For City -owned SCMs, two
categories of ownership are followed to ensure proper maintenance:
• Category 1: Departmental SCMs located within their operating areas are managed and
maintained by the individual departments in tandem with the Facilities Division of the Engineering
Department. Stormwater Management (WR) conducts the inspection and provides each
department with the inspection report findings with requests to maintain, as needed.
o If an SCM was built as a condition of development, the department is responsible for the
maintenance and upkeep of the SCM.
W.
City of Greensboro MS4 Operation and Maintenance Plan
May 5, 2022
o Retrofits that were constructed after the completion of the site that was not a condition of
development are generally maintained by the Facilities Division. Stormwater
Management assists if there is a structural maintenance issue.
Category 2: Some SCMs have no formal ownership, facility, or departmental ownership and do
not fall into the first category. Some retrofits fall into this category. These SCMs have coordinated
maintenance between Stormwater Management and Field Operations.
Table 6 provides a summary of current tasks performed by the City to operate and maintain City -owned
SCMs, including frequency, primary responsibility, and the appropriate guidance document or SOP for
