Where Heartland Meets High Tech
TO: City Council
VIA: Brian J. Borne, Interim City Manager
DATE: August 10, 2021
FROM: Sarah McAllister, P.E., Engineering Director
PREPARED BY: Chris Costner, P.E., CSM, CFM, Stormwater Engineer
SUBJECT: Renewal of NPDES, Phase II Permit Application
SUMMARY STATEMENT
City Council is requested to consider approval of the application for the renewal of the City's NPDES,
Phase I1 Stormwater Permit Application and the Stormwater Management Program report prepared for
submittal to the North Carolina Department of Environmental Quality by the Engineering Department.
REVIEW
The City of Monroe is currently authorized to discharge stormwater from the City's municipal separate
storm sewer system (MS4) in accordance with discharge limitations, monitoring requirements and other
conditions set forth in the City's permit (MS4 permit No. NCS000482). To assure consideration for
continued coverage under the permit; the City must renew its National Pollutant Discharge Elimination
System (NPDES), Phase II Stormwater Permit with the North Carolina Department of Environmental
Quality (NC DEQ). As part of the NPDES Stormwater Permit renewal package, the City must also amend
as required the existing Stormwater Management Plan (SWMP). At a minimum, the SWMP and renewal
permit application must address the following six minimum measures:
• Public Education and Outreach on Stormwater Impacts
• Public Involvement and Outreach
• Illicit Discharge Detection and Elimination
• Construction Site Stormwater Runoff Control
• Post -Development Stormwater Management in New Development and Redevelopment
• Pollution Prevention/Good Housekeeping for Municipal Operations

Staff is expecting no major changes in the six minimum measures, only minor nomenclature changes. The
only changes made to the SWMP other than the minor nomenclature changes was updating the responsible
party contact list due to changes in personnel.
Below is a summary of each measure:
Public Education and Outreach on Stormwater Impacts:
Continue to implement a public education program to distribute educational material to the community or
conduct equivalent outreach activities about the impacts of stormwater discharge on the water bodies and
steps that the public can take to reduce pollutants in stormwater runoff.
Public Involvement and Outreach:
Continue to provide opportunities for the public to participate in program development and implementation.
This includes allowing the public the opportunity to review and comment on the stormwater plan.
Illicit Discharge Detection and Elimination:
Continue to implement and enforce the program to detect and eliminate illicit discharges into the City's
MS4. This includes dry weather water quality sampling.
Construction Site Stormwater Runoff Control:
Continue to implement and enforce the City's erosion and sedimentation control program to reduce
pollutants in any stormwater runoff to the City's MS4 from construction activities that result in a land
disturbance.
Post -Development Stormwater Management in New Development and Redevelopment:
Continue to implement and enforce the City's post -construction stormwater program that addresses
stormwater runoff from new development and redevelopment projects. The program must implement
strategies, which include a combination of structural and/or non-structural best management practices.
Pollution Prevention/Good Housekeeping for Municipal Operations:
Continue to develop and implement an operation and maintenance program that includes a training
component and has the ultimate goal of preventing or reducing pollutant runoff from the City's municipal
operations.
The due date for submitting the NPDES Phase II Stormwater Renewal Permit Application and the
Comprehensive Stormwater Management Program Report is August 23, 2021. Due to the cancellation of
the July 20, 2021 Public Enterprise Committee Meeting, the Chair has approved moving this matter forward
under the Regular section of the August 10, 2021 City Council Regular Agenda.
