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.

4.2 Program Funding and Budget
In accordance with the issued permit, the Town of Indian Trail shall maintain adequate funding and staffing to
implement and manage the provisions of the SWMP and comply with the requirements of the NPDES MS4 Permit.
The budget includes the permit administering and compliance fee, which is billed by the Division annually.

NCS000453 SWMP
Town of Indian Trail
06/10/21
Page 10

The Town collects a utility fee from the residents and businesses based on the amount of impervious area on a
property. Current fee structure breakdown is:

Residential Rate:

Tier 1: < 2,060 square feet = $53.10 annually
Tier 2: > 2,060 square feet = $63.60 annually

Non-residential Rate:

2,060 square feet = 1 ERU = $40.56 annually

The Town annual stormwater budget is around $1.5 mil and is sufficient enough to implement our SWMP and comply
with the MS4 permit requirements.

4.3 Shared Responsibility
The Town of Indian Trail will share the responsibility to implement the following minimum control measures, which
are at least as stringent as the corresponding NPDES MS4 Permit requirement. The Town of Indian Trail remains
responsible for compliance if the other entity fails to perform the permit obligation and may be subject to enforcement
action if neither the Town of Indian Trail nor the other entity fully performs the permit obligation. Table 9 below
summarizes who will be implementing the component, what the component program is called, the specific SWMP
BMP or permit requirement that is being met by the shared responsibility, and whether or not a legal agreement to
share responsibility is in place.

The Town of Indian Trail does not have a shared program with other parties.

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.
