1 Storm Sewer System Information
1.1 Population Served
The Town of Butner has a permanent population, according to the 2000 census, of 5,792. The
2009 census estimate is 6,391. The area does not experience a significant seasonal fluctuation
in population.
1.2 Growth Rate
The population growth rate is estimated to be 2.38% annually. The population grew from 4,679
in 1990 to 5,792 in 2000, based on Census figures, giving a 23.79% change over 10 years, which
annualizes to 2.38%. The Town was incorporated only in 2007 and as a part of that
incorporation acquired significant new land area and population. Thus, the annualized growth
rate, which in part reflects the jump in population that occurred as part of the incorporation, is
higher than the growth rate that Butner is likely to experience in future years.
1.3 Jurisdictional and MS4 Service Areas
The jurisdictional area of the Town of Butner is 13.79 square miles. The MS4 service area is
13.79 square miles.
1.4 MS4 Conveyance System
The storm sewer system for which the Town is responsible primarily comprises roadside ditches
along the 14.9 miles of streets that the Town maintains. Less than one mile of the Town's
system is piped conveyance. Stormwater is conveyed to receiving streams mainly through
ditches. The system's overall condition can be characterized as fair to good. Maintenance is
performed primarily on a complaint basis, and no major problems have been identified.
1.5 Land Use Composition Estimates
The following table lists the current land use composition estimates for the Town:

1.6 Estimate Methodology
Land use classification was initially based on detailed tax assessor data. This was done by
applying the following criteria to the tax data:
Town of Butner DRAFT NCS000544 SWMP Page 1 4
MS4 Butner
January 2022

• residential — parcels that included at least one bedroom or bathroom and where owner
information did not readily indicate that the parcel was a commercial/industrial
business;
• open space — parcels that had a "building value" of zero;
• industrial — parcels that indicated an industrial land use through examinationof
ownership and parcel description;
• commercial — parcels identified by the tax database as "commercial" properties.
These classifications were verified in two ways. First, the land use classification for each parcel
was compared against 2008 aerial imagery of the Town. Changes were made to land use
classification where the imagery indicated that the initial classification was incorrect. Next, the
resulting land use estimates were checked against the estimate used for the Town's
Comprehensive Plan. Note that public roads are excluded from the estimate.
1.7 TMDL Identification
There are no TMDLs for receiving waters.
2 Receiving Streams
The following receiving streams were identified in accordance with the process and criteria
stipulated in the instructions for preparing the Stormwater Management Program Report. The
Town falls entirely within the Neuse River basin.

3 Existing Water Quality Programs
3.1 Local Programs
Butner has implemented the Universal Stormwater Management Program, which encompasses
compliance with NPDES Phase II rules and with the Neuse Nutrient Sensitive Waters
requirements. Water Supply Watershed Protection rules are in effect for the Falls Reservoir, a
WSW -IV class waterbody. Neuse buffers are also required.
3.2 State Programs
In Butner, the State erosion and sediment control program is in effect and, for local or state
construction, the State stormwater program is implemented.

7 Stormwater Management Program
7.1 Public Education and Outreach on Stormwater Impacts
7.1.1 Target Pollutants
The target pollutants for the Town of Butner are nitrogen, phosphorus, and sediment. Nitrogen
and phosphorus are targets for the Town because stormwater runoff in Butner eventually
drains to Falls Lake, a drinking water source for the City of Raleigh. The State Division of Water
Quality has listed Falls Lake on the Clean Water Act 303(d) list of impaired waters due to
chlorophyll -a, a measure of the algal productivity, which is an indicator of nutrient loading. The
Falls Water Supply Nutrient Strategy rules (15A NCAC 02B .0275) require Butner to reduce its
nitrogen loading to Falls Lake by 40% and phosphorus loading by 77% from a 2006 baseline
condition. The goal of these reductions is to improve water quality in the watershed as a whole
and to improve water quality in Falls Lake.
Sediment is the number one water pollutant, by volume, in North Carolina. Sediment degrades
the quality of water for drinking, wildlife, plants, and land by carrying attached pollutants into
receiving waters, increasing the turbidity of waters, affecting the habitats of aquatic life, and
disrupting the natural hydrology of landscapes, among other effects. Runoff from construction
sites has a particularly high concentration of sediment, thus construction site runoff within the
Town is of concern.
Town of Butner Stormwater Management Program Report Page 1 22

7.1.2 Target Audiences
The target audiences for nutrients are the general public, property owners, developers, and
construction site operators. Education on the effects of fertilizers, pesticides and herbicides
will be used to encourage homeowners and property managers to use these products according
to package instructions and to limit their use. The public will also be encouraged to limit energy
consumption and vehicle use and will be advised of benefits of servicing and maintaining their
on -site wastewater systems.
Given the impending Falls rules, the general public, property owners, developers and
construction site operators will also be targeted. In addition to providing education about the
requirements of the new rules and the effects of excess nutrients on water quality, the Town
will provide education about how nutrient load reductions will be accomplished. The specifics
of the Town's load reduction program for existing development are yet to be determined, but
could include physical changes to developed sites, such as removing impervious surfaces or
constructing bioretention areas. Property owners and the general public will be informed of the
need for such measures. Developers and construction site operators will face new
requirements for new developments, such as meeting nitrogen and phosphorus loading
requirements, and they will need information about why the new requirements exist and how
they can meet those requirements.
Because of its relationship to erosion and sedimentation control, the target audiences for
sediment are construction site operators, construction workers, and the general public.
Construction site operators and construction workers have opportunities to alter erosion
prevention and sediment control practices on their sites, which may lead to a reduction in, or
elimination of, sediment releases. The general public may notice releases of sediment and
notify the Town by calling a hotline. Providing education to the public and to young people,
specifically, on the effects of sedimentation on water quality may increase awareness of the
need to protect habitats by preventing sediment contamination.
7.1.3 Outreach Program
The Town's outreach program will inform the target audiences about stormwater through a
number of mechanisms, including a website, a stormwater hotline, a bill insert to water
customers, a brochure for construction workers and construction site operators, a workshop for
developers and construction site operators, public meetings, and community events. Using a
variety of these mechanisms, the Town will attempt to target all Butner residents through the
course of the permit term.
The Town will establish a stormwater page on its website, which will feature information about
stormwater in general, stormwater pollution, ways that individuals can prevent stormwater
pollution, information about the Falls Water Supply Nutrient Strategy and contact/hotline
information for the Town. Pictures may be used to illustrate concepts where advantageous.
The site will be updated periodically with new information.
The stormwater hotline will be an advertised phone number that the public can use to inform
Town staff about stormwater pollution issues.
Town of Butner Stormwater Management Program Report Page 1 23

The Town will develop a bill insert to provide information to the general public about
stormwater. The insert will describe the Falls rules for citizens, the impact individuals can have
on stormwater pollution, and ways citizens can become involved in stormwater programs. The
Town will work with the South Granville Water and Sewer Authority to distribute this bill insert
to water customers.
The Town will develop two brochures: one directed at developers, construction workers, and
construction site operators and one directed at the general public. Each brochure will provide
information about the Falls rules and stormwater pollution. In addition, the brochure for
developers and construction workers will discuss how requirements have changed for new
development.
The Town is a member of the Clean Waters Education Partnership. General stormwater
education and outreach will be provided through the partnership.
Periodically, Town Council meetings and Town Council workshops will be held in which
stormwater is discussed for at least a portion of the meeting. These meetings are open to the
public and are advertised as required by public notice requirements.
The Town will periodically organize and/or participate in community events relevant to
stormwater or water quality, such as stream cleanups. Volunteers will be encouraged to
participate.
The Town will evaluate its public outreach program annually against the measurable goals
described in the table below. The Town will evaluate the success of this minimum measure by
the number of individuals reached through volunteer activities, hotline phone calls received, or
using other evaluation strategies as indicated by the measurable goals for each of the BMPs.

7.2 Public Involvement and Participation
The Town will conduct at least one public meeting to allow attendees to discuss and ask
questions about the stormwater program plan. Attendees will be invited to ask questions or
make comments about stormwater and the Town's policies for stormwater management.
The Town will initiate a stormwater volunteer program. Volunteers will be invited to assist
Town staff in performing stream monitoring and stream cleanups.
To satisfy the requirement for a mechanism for public involvement, citizens will be invited to
participate in stormwater program development and implementation by providing comments
at the public meeting or calling or emailing Michael Ciriello with feedback. The draft plan will be
posted on the Town's website with links to an email address for providing feedback. The plan
will be advertised on the Town's website. In addition, Town staff will attend meetings of local
groups to make presentations related to the stormwater program, accept and address
comments on the program, and invite volunteer participation.
The public involvement and participation program will be evaluated based on the number of
participants and their exposure to public involvement and participation programs. Ideally, this
number will increase from year to year.

7.3 Illicit Discharge Detection and Elimination
7.3.1 Storm Sewer System Map
The Town will create a storm sewer system map marking the major outfall locations and the
names and locations of receiving waters. The map will be added to the Town's existing GIS
database. Data on receiving waters has already been obtained through NCOneMap and will be
updated periodically. The storm sewer system map data will be collected in the field using
handheld GPS or GPS-enabled laptops.
7.3.2 Regulatory Mechanism
The Town's land development ordinance addresses illicit discharges (Section 15.4). Currently,
the Town can achieve elimination of some illegal discharges through cooperation with South
Granville Water and Sewer Authority. Discharges that are identified through complaints or
through the Authority's regular inspections programs can be eliminated through the Authority,
as it already regulates illicit discharges related to the potable water and wastewater system.
Town of Butner Stormwater Management Program Report Page 1 26

7.3.3 Enforcement
The Town does enforce actions related to illicit discharges. See Town of Butner LIDO Section
15.4
7.3.4 Detection and Elimination
The Town will establish written procedures for detecting and tracing the sources of illicit
discharges and for removing the sources or reporting the sources to the State to be properly
permitted. Staff will detect illicit discharges through regular surveillance of outfalls.
Additionally, an illicit discharge record will be initiated when citizens, police, or Town staff calls
to report a suspicious looking spill. A member of the Public Works staff will follow up on the
call in accordance with written procedures. Procedures to identify and report failed septic
systems and sanitary sewer overflows will also be developed during the permit term.
7.3.5 Procedures for Locating Priority Areas
In the course of staff's regular surveillance of outfalls, staff members will look for outfalls and
illegal connections that they have not seen previously, and trace them to their sources. In
addition, staff will prioritize older subdivisions for inspections.
7.3.6 Procedures for Tracing the Source
To remove the source of an illicit discharge, the staff member will notify the suspected
discharger via the NOV process developed indicated in section 7.3.3.
7.3.7 Procedures for Removing the Source
To remove the source of an illicit discharge, the staff member will notify the suspected
discharger via the NOV process developed indicated in section 7.3.3.
7.3.8 Procedures for IDDE Evaluation
In the future, staff plans to collect location data on suspected, identified and/or eliminated
illicit discharges using parcel addressing and a Global Positioning System (GPS) device. The data
will be kept on the Town's GIS database and examined periodically. This will allow staff to
identify any patterns that may be occurring.
Town of Butner Stormwater Management Program Report Page 1 27

7.3.9 IDDE Outreach
The stormwater hotline will be the primary method used by the Town for the receipt of illicit
discharge complaints. The hotline will advertised on the Town website and in the water bill
insert described in section 7.1.3. Other mechanisms through which the Town can receive illicit
discharge information from citizens include the Town's general information number or email to
the appropriate Public Works staff.
Public Works staff members will attempt to respond to non -anonymous citizen complaints with
one-on-one contact (call, meeting, email, etc.) with the complainant. This is recognized as an
opportunity to both gather further information about the suspected discharge, and to educate
the complainant about illicit discharge detection and elimination.
The hazards of illicit discharges and illegal waste disposal will be addressed in both brochures
the Town develops as part of its Public Outreach program and on the Town's stormwater
website.
7.3.1 Staff Training
The Town will provide training to Public Works staff in the identification of and response to
illicit discharges.
7.3.2 Evaluation
The illicit discharge detection and elimination program will be evaluated by the number of illicit
discharges and the number of repeated illicit discharges found at the same location.

7.4 Construction Site Stormwater Runoff Control
The Town's erosion prevention and sedimentation control is managed by the state's Erosion
and Sedimentation Program under the North Carolina Sedimentation Pollution Control Act of
1973. Requirements for erosion and sediment controls are codified in 15A NCAC Chapter 4. The
State also provides the North Carolina Erosion and Sediment Control Planning and Design
annual, which offers details and procedures for developing site -specific erosion and
sedimentation control plans in accordance with the Sedimentation Pollution Control Act and
the administrative rules.

7.5 Post -Construction Stormwater Management: New Development,
Redevelopment
The Town has adopted North Carolina's Universal Stormwater Management Program (USMP)
As such, the Town has adopted the USMP requirements for stormwater design.
7.5.1 Regulatory Mechanism
The Town's Land Development Ordinance is in compliance with the USMP. The Town's Design
Manual provides policy, criteria and technical specifications and standards for stormwater
permits and the design, implementation and performance of post -construction management
structural and non-structural controls.
7.5.2 Operation and Maintenance
The Town's Land Development Ordinance requires that each structural BMP be maintained and
operated so as "to preserve and continue its function in controlling stormwater quality and
quantity at the degree or amount of function for which the structural BMP was designed" (see
15.7.1, Standards for Maintenance, of the Land Development Ordinance, included as an
appendix to this report). The person responsible for maintenance of the BMP must submit an
annual inspection report to the Town. This inspection report is completed by a professional
engineer, surveyor, landscape architect, soil scientist, aquatic biologist, or person certified by
the North Carolina Cooperative Extension Service for stormwater treatment practice inspection
and maintenance. Prior to issuing a permit for development or redevelopment that requires a
structural BMP, the applicant or owner must execute an operation and maintenance agreement
that is binding on all subsequent owners of the site. This requires the owner to maintain, repair
and, if necessary, reconstruct the BMP and states maintenance terms and a schedule.
Under the USMP requirements, all residential development in the Town that disturbs an acre or
more and all commercial development disturbing a half -acre or more is required to control and
treat stormwater runoff generated by a one -inch rain event. At a minimum, these control and
treatment measures must remove 85% of total suspended solids and a have a volume
drawdown of at least 48 hours, but not more than 120 hours. In addition, the storage volume of
Town of Butner Stormwater Management Program Report Page 1 30

the stormwater control device must be discharged at a rate equal to or less than the pre -
development discharge rate for the 1-year, 24-hour storm. In the critical areas of water supply
watersheds, new development is limited to an impervious surface density of no more than 36
percent.
7.5.3 Fecal Coliform
The Town will coordinate with the Granville -Vance District Health Department to control known
sources of fecal coliform to the maximum extent practicable. Onsite wastewater systems are
permitted by the Granville -Vance District Health Department based on site evaluations
performed by the Health Department, which also investigates complaints regarding
malfunctioning onsite wastewater systems. If the Health Department finds a problem,
recommendations are made for corrective action.
7.5.4 Nutrient Sensitive Waters
The Town's participation in the USMP meets requirements for development and
redevelopment draining to nutrient sensitive waters. The Town does not currently have a
nutrient application management program, but will develop and implement one under this
NPDES permit.
7.5.5 Non -Structural BMPs
As part of the USMP program, the Town has a setback requirement that prohibits new
impervious surfaces within 30 feet of all perennial and intermittent surface waters. No new
impervious or partially pervious surfaces, except for roads, paths and water dependent
structures, are allowed in the floodplain.
In addition, the Town's Land Development Ordinance requires that planned unit developments
(PUDs) preserve environmentally sensitive areas, including all wetlands, steep slopes, and
floodways, as open space. A minimum of 20% of the gross area of a PUD must be open space,
and no more than 50% of the dedicated open space can be used for active recreation purposes.
7.5.6 Structural BMPs
The Town requires structural BMPs for stormwater treatment in accordance with the adopted
USMP. To date, three BMPs have been implemented and two are under construction. Two
additional BMPs have been implemented on sites that were formerly under County land use
controls.
7.5.7 Natural Resource Protection
As described in the previous section, the Town has a setback requirement that prohibits new
impervious surfaces within 30 feet of all perennial and intermittent surface waters. No new
impervious or partially pervious surfaces, except for roads, paths and water dependent
structures, are allowed in the floodplain.
7.5.8 Open Space Protection
The Town has not implemented open space protection.
Town of Butner Stormwater Management Program Report Page 1 31

7.5.9 Tree Preservation
Article 11 of the Town's Land Development Ordinance provides incentives for developers to
preserve and protect existing mature trees in conjunction with new development. Developers
receive credit of 1.5 times the number of preserved trees to be used towards the tree planting
requirements for landscaping and buffering for each tree preserved and protected in
accordance with the standards of the article. Approved tree preservation credits may be
applied to the tree planting requirements for streetyard landscaping, motor vehicle use area
landscaping, street trees, or perimeter buffers. However, tree preservation credits cannot be
used to offset more than 50% of the required number of trees in the area to which they are
applied.
Street trees are required to be planted on both sides of new public or private streets
established through the major subdivision process. These trees must have a minimum mature
height of 20 feet and must be a minimum of eight feet high and two inches in diameter (at six
inches above the ground) at the time of planting.
The Town's Land Development Ordinance allows for Mixed Residential Districts, which are a
combination of residential development and "complimentary public and institutional uses
which would not detract from the residential character of the district."
7.5.10 Street Design
The Town's Land Development Ordinance requires streets to be built to North Carolina
Department of Transportation standards. The Town has not green infrastructure street design
elements to date.
7.5.11 Reduced Parking Requirements
The Town has not implemented these elements to date.
7.5.12 Transportation Demand Management Alternatives
The Town has not implemented Transportation Demand Management Alternatives to date.
7.5.13 Green Infrastructure
The Town has not implemented Green Infrastructure requirements to date.
7.5.14 Minimizing Stormwater from Parking Lots
Landscaped planting areas are required for all motorvehicle use areas developed in accordance
with the Land Development Ordinance. One landscaped planting area is required for every
2,500 square feet of motor vehicle use area. Each planting area must contain at least one tree
with a minimum height of eight feet and a minimum diameter of two inches, as measured six
inches above the ground. Each parking space within a motor vehicle use area must be within at
least 60 feet of the trunk of a required tree. These trees may be clustered around loading
docks or other maneuvering areas.

7.5.15 Maintenance/Enforcement
Stormwater BMPs are maintained and enforced through the mechanisms described in section
7.5.2. Annual reporting is required for BMPs on private land. Development of structural BMPs
will be tracked using a database, which will also track annual reporting.
7.5.16 Evaluation
Post -construction stormwater management will be evaluated by the number of BMPs that are
evaluated annually and found to be in good working condition and the number of annual
reports received.

7.6 Pollution Prevention/Good Housekeeping for Municipal
Operations
The Town will implement an operations and maintenance program with the goal of preventing
or reducing pollutant runoff from municipal operations. This program will include staff training
and documentation of procedures and activities.
7.6.1 Affected Operations
The Town currently operates a public works facility where routine maintenance to vehicles is
conducted. The Town maintains the stormwater drainage system, including ditch cleaning and
repair. The Town maintains parking lots on its current Town Hall, Sports Arena, and storage
building sites, as well as on a gravel lot adjacent to a ball field. As part of parks and open space
maintenance, the Town operates the Sports Arena, D Street Ball Fields, and Gazebo Park. The
site for the new Town Hall is under construction and will include the Town Hall building as well
as an athletic park. The Town will establish procedures for pollution prevention and good
housekeeping for these operations.
The Town's sole industrial -type facility is the Public Works facility. The Town is in the process of
seeking a no exposure certification exclusion for this facility.
7.6.2 Training
The Town will conduct an annual training for staff involved in municipal operations and
maintenance activities. The training will cover both basic stormwater education and specific
pollution prevention practice information pertaining to the Town's operations. The program
will convey the same information as the public education outreach efforts, including illicit
discharge detection and elimination -specific outreach, with the goal of contextualizing inquiries
and questions that staff may receive from citizens. The illicit discharge detection and
elimination portion of the training will also focus on enabling staff to spot potential illicit
discharges and, when IDDE standard operating procedures are complete, to familiarize staff
with the Town's SOPs for discharge elimination.
7.6.3 Maintenance and Inspections
The Town does not own permanent stormwater controls. For new stormwater controls that are
installed to comply with the Falls Rules and state stormwater quality requirements, the Town
will establish a program of regular inspections and maintenance for the facilities. The Town will
establish a regular inspections program for the storm drainage system.
7.6.4 Vehicular Operations
Routine maintenance for vehicles is conducted at the Public Works facility. Maintenance
activities are conducted indoors. Vehicle washing is conducted in a commercial carwash or on a
grassed surface. The facility is maintained in an orderly manner, materials are stored indoors,
and spill kits are maintained and used when necessary. The Town owns several parking lots.
Town of Butner Stormwater Management Program Report Page 1 35

Litter collection is performed regularly at these lots. These practices will be continued as part
of the Town's compliance with this permit.
7.6.5 Waste Disposal
The Town will formalize procedures for waste disposal as part of its program development,
including pollution prevention for stockpiled materials. Used motor oil, antifreeze, filters and
vehicle fluids used in routine maintenance are disposed at the County landfill's used oil
recycling collection point.
7.6.6 Evaluation
The pollution prevention and good housekeeping program will be evaluated according to
pollution prevention standard operating procedures created and implemented and staff
training completed.
