Dear Khan,
I had submitted a DRAFT report mid-June 2021 for review. I had presumed that your staff
would want to review it first before the Town submits a FINAL report since the Town was in a
violation period. I haven't heard back from anyone, so I didn't won't to hold off any longer in
submitting the NPDES MS4 Permit Application form. Please see enclosed application and the
Town's SWMP report. We are actively pursuing our goals for this year and look forward to the
review come next year.
Also, I would like to include that per the Town's Unified Development Ordinance (UDO), my

PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Town of Indian Trail will comply with its National Pollutant Discharge Elimination System (NPDES)
Municipal Separate Storm Sewer System (MS4) Permit and the applicable provisions of the Clean Water
Act to meet the federal standard of reducing pollutants in stormwater runoff to the maximum extent
practicable.
This SWMP identifies the specific elements and minimum measures that the Town of Indian Trail 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 NCS000453, 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 Indian Trail and located
within the corporate limits of the Town of Indian Trail.
In preparing this SWMP, the Town of Indian Trail 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, are incorporated by reference into the permit and become
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.

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
In accordance with 15A NCAC 02H .0153, the Town of Indian Trail relies upon the North Carolina Sedimentation
Pollution Control Act(SPCA)of 1973 as a qualifying alternative program to meet a portion of the NPDES MS4 Permit
requirements for construction site runoff control measures. 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.

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
projects less than one acre that are part of a larger common plan of development or sale,that are located within the
Town of Indian Trail 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.
In accordance with 15A NCAC 02H .0153 and .1017,the Town of Indian Trail 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.

Dear Khan,
I had submitted a DRAFT report mid-June 2021 for review. I had presumed that your staff
would want to review it first before the Town submits a FINAL report since the Town was in a
violation period. I haven't heard back from anyone, so I didn't won't to hold off any longer in
submitting the NPDES MS4 Permit Application form. Please see enclosed application and the
Town's SWMP report. We are actively pursuing our goals for this year and look forward to the
review come next year.
If you should have any questions about this submittal, please reach out to me at
