PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Town of Black Mountain 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 Black Mountain
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 NCS000422, 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 Black Mountain and
located within the corporate limits of the Town of Black Mountain.
In preparing this SWMP, the Town of Black Mountain 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.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Town of Black
Mountain as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do
not significantly impact water quality. The Town of Black Mountain has evaluated residential and charity
car washing and street washing for possible significant water quality impacts.
Street washing discharges are addressed under the Pavement Management Program in Part 10 of this
SWMP. The Division has not required that other non-stormwater flows be specifically controlled by the
Town of Black Mountain.
Wash water associated with car washing that does not contain detergents or does not discharge directly
into the MS4 is considered incidental. However, these types of non-stormwater discharges that do

PART 4: STORMWATER MANAGEMENT PROGRAM ADMINISTRATION
4.1 Organizational Structure
The Stormwater Program is created and managed by the Planning Director with close collaboration of
Public Works and support of the Town Manager. The Planning Director manages administration, policy
outreach and implementation of the plan. The Public Works Director and staff provide information about
current conditions and support implementation. Public Works staff is the boots on the ground, improving
draining systems, managing infrastructure and are the first line of defense (along with residents) in
stopping illicit discharges and connections. The Town is actively pursuing a stormwater utility and will
hire a stormwater field tech when adopted.
This is the organization chart for Public Works. Those positions noted in red indicate hands on service

4.2 Program Funding and Budget
In accordance with the issued permit, the Town of Black Mountain 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
NCS000422 SWMP
Town of Black Mountain
April 2021
Page 13
by the Division annually. The funding for the stormwater program comes exclusively from fund balance;
however, the town is formally exploring establishing a stormwater utility.
The town also seeks grants for projects to improve stormwater quality and reduce stormwater quantity as
they become available. The town acknowledges the lack of appropriate funding and is committed to
finding ways to increase program funding. These grants are used for typically used for SCM installation
and stream restoration projects. Not all of these projects are directly related to NPDES compliance,
however, do hold benefit to the watershed in general.
The town has completed a stormwater utility study. The Town Council will consider the proposal for
adoption and implementation in FY 21-22. Projected revenue will vary on adopted rate structure, but
could be approximately $350,000 per year.
Currently the town funds staff positions of which a percentage of their work is related to stormwater. A
conservative estimates of these percentages are:
Public works crews $56,000
Public Works Director $15,000
Town Manager $20,000
Planning Director $15,000
Building Inspector $8,000
Total $114,000
4.3 Shared Responsibility
The Town of Black Mountain 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 Black Mountain 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 Black Mountain 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.

PART 5: PUBLIC EDUCATION AND OUTREACH PROGRAM
The Town of Black Mountain will implement a Public Education and Outreach Program to distribute
educational materials to the community or conduct equivalent outreach activities about the impacts of
storm water discharges on water bodies and steps the public can take to reduce pollutants in storm water
runoff.
The target audiences and identified pollutants listed in Part 3.9 of this SWMP , which will be addressed by
the Public Education and Outreach Program, are summarized in Table 12 below. In addition, the Town of
Black Mountain is required to inform businesses and the general public of the hazards associated with
illicit discharges, illegal dumping and improper disposal of waste.
Select Achievements
• In 2019 the Town held two well-attended workshops in partnership with RiverLink. The first was
a rain garden installation and certification course. The second was designed to teach citizens with
river/stream property how to be resilient and manage their property in a way that is
environmentally sensitive.
• Staff also launched a new highly informative website for citizens and developers to utilize.
• The stormwater hotline has been established and promoted through a variety of outlets, including
a “report-a-polluter” flyer sent out in over 3,000 water bills.
• Stormwater activity books were created and given to third grade classes participating in Town
Hall Day in November.
• Stormwater materials are now included in the development resources provided to
homeowners/contractors/developers when applying for permits.

The town has been successful in engaging these communities using social media, partnering with
RiverLink and the town’s Beautification Committee, to help get information into the community. The
pandemic has made working with schools more difficult, but we have e-mail links to activities and videos
that could be used during remote learning. We also include stormwater information into the Citizen’s
Academy, which is held once a year.
The Town of Black Mountain will manage, implement and report the following public education and
outreach BMPs.

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
In accordance with 15A NCAC 02H .0153, the Town of Black Mountain relies upon the North Carolina
Sedimentation Pollution Control Act (SPCA) of 1973 and the NCG010000 permit for construction
activities as qualifying alternative programs to meet the NPDES MS4 Permit requirements for all
construction site runoff control measures to reduce pollutants in stormwater runoff from construction
activities that result in land disturbance of greater than or equal to one acre and any construction activity
that is part of a larger common plan of development that would disturb one acre or more.
Select Accomplishments
• The Town recently updated the post-construction ordinance. The area disturbed to require this
particular permit is now 5,000 square feet and the storm size is now a 10-year storm.
• All permits are screened for the stormwater requirement, by the zoning administrator.
• The Building Inspector supports the stormwater plan process by fielding questions and providing
the application package to the Town’s consulting engineer who determines if the applicant has
met the standards of the ordinance.
