- J. STORMWATER MANAGEMENT PROGRAM
PRELUDE
This Stormwater Management Plan (SWMP) serves as a legal binding, guiding document for the City of
Winston-Salem's Stormwater Division to znaiiitaiii permit compliance of divisional operations. By evaluating
the prior year's Stormwater Annual Report(SAR),in conjunction with a programmatic gap analysis, Stormwater
staff will create and/or maintain measurable goals to enhance anticipated water quality improvements. The
SWMP will be modified by the Assistant Stormwater Director or Stormwater Operations Analyst on an annual
basis. The Stormwater Division has decided to update this SWMP during the month of October to coincide with
the beginning of the new permit year. Once this document has been approved by the City of Winston Salem's
Field Operations Director,the Plan will be submitted to the North Carolina Department of Environmental Quality
(NCDEQ)for final approval. After approval has been issued by NCDEQ to the Stormwater Division, the action
items of this Plan will be implemented by the responsible Stormwater staff member.
MISSION STATEMENT
The mission of Stormwater Management is to restore,protect, and preserve the surface waters within the City of
Winston-Salem and to maintain, repair, map, and evaluate drainage systems within the street right-of-ways.
PROGRAM DESCRIPTIONS
Stormwater Monitoring and Administration: Manages the day-to-day operations of the Stormwater
Management Program. Implements the requirements of the City's Municipal Separate Storm Sewer System
(MS4) permit. Performs watershed master planning by developing maps and inventories of the entire drainage
system within the City. Monitors Stormwater run-off as part of the program's efforts to improve water quality.
Provides educational programming to increase public awareness of water quality issues.
Drainage Maintenance: Repairs,replaces, and upgrades the City's drainage system within street right-of-ways.
Provides for drainage system repairs on private property through the 70/30 program in which the City covers
70% of the cost for qualified projects. Removes debris from culverts and bridge abutments with many streams
and creeks.
Erosion Control: Provides for the enforcement of regulations pertaining to land-disturbing activity, watershed,
and floodplain requirements by reviewing development plans and issuing grading permits for all commercial
and multi-family sites over 10,000 square feet in all areas of Forsyth County, excluding Kernersville. Monitors
single family construction sites to ensure that sediment is controlled. Identifies tree save and potential critical
areas, controls sedimentation, and limits the time of exposure on all applicable construction sites through plan
review and field inspection. Maintains up-to-date floodway district maps to enforce floodway and floodway
fringe regulations contained in the Unified Development Ordinance. Reviews survey and plan information and
conducts field inspections to ensure that permitted structures comply with floodplain regulations. Enforces
watershed regulations for density and impervious coverage on developed properties.
Street Sweeping: Regenerative street sweepers are used year-around to remove litter, debris, and sediment from
roads. Sweeping protects water quality by preventing materials from entering the storm drains. All debris swept
is disposed of in the sanitary landfill.

2. STORM SEWER SYSTEM INFORMATION
2.1 Population Served:
Winston-Salem is in the northwestern area of the Piedmont Region of North Carolina.
Situated in Forsyth County, Winston-Salem is the fifth largest city in North Carolina and
has an estimated population of 250,320 citizens (based on data from the U.S. Census
Bureau, as of July 1, 2021).
2.2 Growth Rate:
The City of Winston-Salem increased its population size by 0.4 percent from April 1,
2020, to July 1, 2021,while the State of North Carolina grew at the rate of 1.1 percent
during the same period.
2.3 Jurisdictional and MS4 Service Areas:
The City of Winston-Salem does not have any ETJ areas, currently. The square mile area
for the City is 132.45.
2.3a Latitude of Center of MS4 Area: 36 degrees 06' 9.95"N
Longitude of Center of MS4 Area: 80 degrees 15' 37.77" W
2.3b Storm Sewer Service Area(square miles): 132.45
2.4 Municipal Separate Storm Sewer System (MS4):
The City of Winston-Salem is authorized to discharge stormwater from its municipal
separate storm sewer system (MS4) into the waters of the State of North Carolina. A
National Pollutant Discharge Elimination System(NPDES) permit is the legal mechanism
that allows the City of Winston-Salem to discharge stormwater runoff into streams. All
six minimum measures, which govern the City of Winston-Salem's Stormwater Program,
are contained within this permit.
The City of Winston-Salem is delineated into 17 different sub-watersheds that drain the
City and its surrounding area. The streams, within these sub-watersheds, flow in a
southwesterly direction into Lower Muddy Creek; the original fifteen watersheds had
stormwater masterplans developed for staff by a consultant. Current objectives of
masterplan efforts include providing a comprehensive update of the existing storm sewer
inventory (contained within public, private, and industrial properties), identify existing
and future areas of flooding based on existing and future development patterns, and assess
the impacts of stormwater discharges on the quality of Winston-Salem's streams.
Information obtained from those plans show that Winston-Salem has approximately 538
miles of stormwater conveyance piping and 39,818 infrastructure devices, which includes
catch basins and manholes. Based on the city's current GIS layer, there are approximately
547 miles of perennial and intermittent streams within the municipal boundaries of
Winston-Salem.
2.4a MS4 maintenance activities:
Cave-in reports are responded to within 24 hours of first knowledge of occurrence with
simple repairs being completed within 72 hours. Maintenance activities include the
following services of catch basin inspection and cleaning, pipe repair, replacement and
upgrade projects, ditching (performed by hired contractors or in-house crews), and street
sweeping activities are performed by in-house services.

Best Management Practices (BMPs) for Public Education and Outreach
8.1(a) Describe Target Pollutants, Sources, and Audiences: The Stormwater Division uses three
resources in order to identify and target pollutants of concern within,local waterways of
Winston-Salem: regulatory requirements, fixed interval stream sampling, and historical illicit
discharge detection and elimination reports. Regulatory requirements are derived from Total
Maximum Daily Loads (TMDL)that the City of Winston Salem must reduce waste load
allocations to Muddy and Salem Creeks (currently, the High Rock Lake TMDL is pending). For
the Muddy Creek TMDL, the pollutant of concern is turbidity (i.e., TSS). Most probable sources
of turbidity (TSS) loading include construction sites, in-stream channel erosion, and industrial
sites. Fecal coliform is the pollutant of concern from Salem Creek Watershed. Bacterial source
tracking (BST) confirmed that sanitary sewer overflows,pet waste, and wildlife populations
contribute to fecal coliform pollution. Once the High Rock Lake TMDL is approved, nutrients
will be target pollutants of concern. Fecal coliform and turbidity pollution degrades biotic
integrity,thus impairing the reproduction cycle of aquatic life within streams.
The Stormwater Division performs quarterly, fixed interval sampling to determine pollutant
exceedances (when compared to Water Quality Redbook Standards) within streams. Since
samples are collected during various weather conditions (e.g., dry, first flush, descending portion
of a hydrograph, etc.), an accurate assessment of target pollutants has been established. Since
2011,the Stormwater Division has observed City-wide trending sample data that consistently
shows evaluated concentrations of numerous pollutants. These pollutants of concern consist of
turbidity (i.e., TSS), fecal coliform, and nutrients (i.e., total nitrogen, total Kjeldahl nitrogen,
total phosphorus, and dissolved phosphorus). Probable sources of nutrient exportation include
15

8.1(d) Distribute Public Education Materials to Identified User Groups: The City of Winston
Salem distributes public educational materials that directly relates to specific, targeted audiences.
The City creates communicative information for ranked pollutants of concern, such as floatables,
fecal coliforms, oil and grease, sediment (i.e.,total suspended solids), and nutrients. Educational
materials (and opportunities) include brochures (paper and electronic), presentations, TV
advertisements, social media posts, workshops, community events, and targeted mailings. The
city of Winston-Salem performs mass media outreach activities throughout the local area works
in conjunction with the Piedmont Triad Regional Council (via Stormwater SMART).
Stormwater SMART develops TV and radio public service announcements, social media posts,
digital advertisements, and brochures (paper and electronic)to supplement the City's own
education and outreach efforts. To ensure the maximum educational effectiveness, the City
correlates the informative technique to the targeted audience. For example, best management
practices brochures are written in Spanish for Hispanic automobile repair shops.
81(e) Promote and Maintain a Stormwater Hotline/Helpline: In 2005, City Council commissioned
the creation and implementation of a centralized telephone call center/web-based complaint
hotline for the citizens of the City of Winston-Salem. Known to the public as CityLink, this
communication center receives citizen-generated e-mails or telephone calls regarding
stormwater-related items illicit within the City. The public can access CityLink from the city of
Winston-Salem's homepage of https://www.eikYofws.org/; the CityLink button appears at the
top portion of the City's homepage and the CityLink contact information appears at the bottom
of all City webpages. On the Stormwater Division's homepage on the city website, the CityLink
contact information is provided at the top of the page. The Senior Community Educator receives
electronic notifications for presentation requests from CityLink or directly from website requests.
Illicit discharges are received through the Stormwater Pollution Hotline [phone]), which
is operated by CityLink. CityLink refers all illicit discharge complaints to Stormwater staff, who
will investigate these reports within 24 hours.
8.1(1) Implement a Public Education and. Outreach Program: The Senior Community Educator
records the reach and extend of all educational outreach activities during the active permit year.
As a component of the annual program assessment, the Senior Community Educator evaluates
each educational approach that was used to reach targeted audiences. If needed, educational
techniques or methodologies are modified for maximizing the greatest reach for the upcoming
permit year.
8.7 Public Education and Outreach Annual Reporting Task Items for PY 2022-2023:
1. The Senior Community Educator will provide a summary of all completed educational and
outreach activities (with corresponding workload data or outcomes)that bolster permit
compliance to DEQ.
2. Based on IDDE report data, Stormwater staff determined that the pollutants of concern(POCs)
for citizens are fecal coliforms (blocked sewer lines, failed septic tanks, and illegal sewer
connections), offsite sedimentation, and yard waste/woody debris. For commercial users, the top
two POCs are car-washing wastewater and fats, oil, and grease (FOG). The Senior Community
Educator will create and/or distribute educational materials to identified, targeted audiences.
3. Erosion Control's and Stormwater's webpages will be updated with POC information for
targeted audiences. For this permit year, construction site runoff, TMDL, and water quality

9.1(a) Volunteer Community Involvement Program: The City of Winston-Salem has implemented
the following programs to various degrees in order to promote volunteer opportunities and
ongoing citizen participation:
• Creek Week is a week-long series of events geared to engage the public and support water
quality awareness. Events usually include Creek Crawls,photo contest, guided paddles
and nature walks, lunch and learn presentations, a community read and book discussion,
professional development workshops, homeowner and resident workshops, special
children and teen's programs at the public libraries, community clean-ups, water centered
recreational activities, and other interactive programs. Creek Week occurred in March
and organized by a committee of municipal, county, and non-profit organizations.
• Creek Crawls are held with local school classes where the students visit a nearby creek to
examine the water quality of the stream using water quality test kits and visual
observations. Benthic macroinvertebrates are collected, examined, and discussed as to
form an overall assessment of the water quality of the selected stream. Students are
taught to collect wafter samples and to identify the macroinvertebrates collected based on
provided keys as part of this `hands on' approach.
• The Stormwater Division co-coordinates the Adapt-A-Stream program with Keep
Winston-Salem Beautiful to reduce litter, debris, and floatables in our waterways.
Homeowner associations, companies, special interest groups, families, or other interested
parties can request to Adopt-A-Stream in their area of interest. Interested parties will
commit to conducting three clean-ups per year and the City will provide signage and
debris removal after each cleanup. Keep Winston-Salem Beautiful also coordinates
Adopt-A-Strect and Adopt-A-Park programs to reduce litter, debris, and floatables in our
community.
• Big Sweep is conducted every year in October to remove trash and debris from local
waterways.
• The Great American Clean-Up in Winston-Salem is conducted every year in April to
remove trash and debris from local streets, parks, and waterways.
• The Stormwater Division coordinates the Storm Drain Marking program where volunteer
groups place adhesive `No Dumping, Drains to Creek' markers or use a provided storm
drain marking stencil and spray paint on catch basins and other drainage structures within
the community. Volunteer groups also distribute door hangers that contain stormwater

volunteer, and public participation activities (with corresponding workload data) that bolster
permit compliance to DEQ.
2. Citizens attend monthly Public Works Committee Meetings to participate in the stakeholder
process. The Public Works Committee invites citizens to participate in these discussions and
agendas are posted on the City's website. In addition, the City Council has created
Stormwater Appeals Board, which makes decisions of various ordinances.
3. The Senior Community Educator will report the total number of stormwater-related calls
through CityLink to DEQ.
4. The Stormwater program website will be reviewed and updated with information for citizens.
The dates of all webpage updates, with a summary of uploaded information, will be reported

10.1(a) Maintain Appropriate Legal Authorities: The City of Winston-Salem has an illicit discharge,
connection, and disposal ordinance that regulates the introduction of illegal pollutants to the
City's MS4 and receiving streams. The ordinance was adopted by City Council in 2006.
Stormwater staff possesses adequate regulatory authority to provide enforcement actions, which
include enforcement mechanisms, such as issuance of notice of violations, levy civil penalties,
and issue stop work orders. One can reference the City's Stormwater Illicit Discharges and
Connection Ordinance, Chapter 75, at ARTICLE I. ILLICIT STORMWATER DISCHARGES
AND CONNECTIONS
10.1(b) Maintain a Storm Sewer System Base Map: The City of Winston-Salem has entered into a
professional services contract with HDR Engineering for major outfall identification as well as
creation of a comprehensive stormwater system inventory. For FY 2021-2022, Middle and
Lower Mill Creek Subwatersheds are in the process of being surveyed and updated for a
comprehensive stormwater inventory revision, which includes location of new major
stormwater outfalls.
23

10.2 Illicit Discharge Detection and Elimination Annual Reporting Task Items for FY 2022—

11. Continue to use CCTV or a pole camera to locate and permanently remove illicit discharge
sources from the MS4 or local streams.
12. Assess and update (if needed) Stormwater's Illicit Discharge Detection and Elimination Standard
Operating Procedures (SOPS) for determination of accepted staff protocols. This assessment will
occur on an annual frequency.
13. Record the number of detected sanitary sewer overflows by Stormwater staff and reported to
Utilities Construction and Maintenance Section. Continue accessing the sewer overflows data
base that Utilities maintains on a GIS system to determine problem areas for observable trends.
14. Continue coordinating with the Utilities Division for determining potential illicit discharges when
encountered. Stormwater staff will provide professional knowledge and testing equipment for
evaluating potential releases.

11. CONSTRUCTION SITE RUNOFF CONTROLS
Objectives:
l. Reduce pollutants in stormwater runoff from construction activities disturbing one or more
acres of land surface and those activities less than one acre that are part of a larger
common plan of development.
2. Provide procedures for public input, sanctions to ensure permit compliance, requirements
for construction site operators to implement appropriate erosion and sediment control
practices, review of site plans, which incorporates consideration of potential water quality
impacts, and procedures for site inspection and enforcement of control measures.
3. A locally delegated program that meets or exceeds the state requirements covering the
jurisdictional area of the permittee complies with the required minimum of this section.
4. The City of Winston-Salem has been delegated by DEMLR to establish a local erosion
and sedimentation control program to administer the Sedimentation Pollution Control Act
of 1973; stormwater NPDES permit requirements will be fulfilled using this existing
program.. Grading permits are required for land disturbing activities that are greater than
(or equal to) 20,000 square feet for new single-family dwelling construction (or part of a
larger common plan of development) or greater than 10,000 (or equal to) square feet for
any non-exempt purpose (or part of a larger common plan of development). For single-
family dwelling sites under 20,000 square feet(and not in a larger common plan of
development), an executed erosion control affidavit is mandated, which stipulates the
installation of minimal erosion control measures to prevent off-site sedimentation.

11.1(a) Erosion and Sediment Control Program: The Erosion Control Division of the City of
Winston-Salem's Field Operations Department require erosion and sediment control measures
at construction sites. Chapter 8, Section 8.4 of the Unified Development Ordinance regulates
land disturbing activities within Forsyth County's boundaries (this includes the City of
Winston-Salem). For additional information regarding the City's Sediment and Erosion Control
Ordinance,please visit this link: Chapter 8. Section 8.4.
11.1(b) Plan Review Process: Chapter 8, Section 8.4 of the Unified Development Code, Section 8.4.4
(A.) states that no person shall initiate any land disturbing activity upon a tract without having
an erosion control plan approved by the Director or a designee and without having purchased
the applicable permit through the Inspections Division office. Section 3.2.7 (A.) states that any
area exceeding 20,000 square feet in surface area on one tract for construction of a single-family
dwelling or 10,000 square feet on one tract for any other non-exempt purpose must be
permitted. To be permitted, Section 8.4.4 (A.)mandates the creation and submittal of an
erosion control plan, Section 8.4.17 provides the submittal standards and criteria of erosion, and
sedimentation control plans to be reviewed, approved, and installed. When finalized,
development plans are submitted to the City of Winston-Salem for permit approval of land
disturbing activities; Erosion Control staff determines regulatory compliance in accordance with
the Sedimentation Pollution Control Act of 1973 and Chapter 8, Section 8.4 of the City of
Winston-Salem Unified Development Ordinance. As a result, sediment control devices for
construction activities are evaluated for capture of 75 percent of the 40-micron particle and
larger.
11.1(c) Field Inspections, Complaint Response, and Enforcement Procedures: Site inspections are
conducted by one of three qualified Erosion Control Inspectors, which are assigned to a specific
section of Forsyth County. One Erosion Control Inspector is solely dedicated to inspecting
single family dwelling erosion control compliance. Inspector responsibilities include plan
review and approval, issuance of grading/erosion control permits for construction activities,
conducting on-site inspections, and performing enforcement actions, when needed. Routine site
inspections are performed approximately once every three weeks; however,the frequency of
inspections will increase (as needed) for overall programmatic compliance.
Enforcement action provisions are described in Chapter 8, Section 8.4.20 of the City's Unified
Development Ordinance (Chapter 8). The Erosion Control Division will not issue a grading
permit for a development site unless the sediment and erosion control plan has been approved.
Deviation from the approved plan will result in a Notice of Violation (NOV) issued by the
Erosion Control Inspector with required corrective actions and a compliance due date for
29

11.2 Eminent Domain Authority: The Erosion Control Division has an established procedure of
requiring documentation of review and approval of a post-construction stormwater management
plan by DEQ for all development activity within Forsyth County. Municipalities that are
excluded from this policy include Winston-Salem, Kernersvilie, Clemmons, and Lewisville,
since each municipality has its own delegated post-construction stormwater program. This
protocol provides DEQ the opportunity to collaborate with the Erosion Control Division
concerning the approval of a post-construction stormwater management plan within the county
where no post-construction stormwater management program exists.
11.3 Construction Site Runoff Control Annual Reporting Task Items for FY 2022 - 2023
1. The Erosion Control Division will review and approve submitted erosion control plans
and perform corresponding onsite inspections to verify compliance. The annual total of
approved plans as well as onsite inspections will be reported to DEQ.
2. Once the state's new model ordinance is adopted by the Sedimentation Control
Commission, Erosion Control staff will perform a gap analysis and progress with local
ordinance revisions, if needed. An update of this action item will be included in the
upcoming annual report.
3. If needed, staff will issue Notices of Violations and use all enforcement actions outlined in
Chapter 8, Section 8.4 of the City's Unified Development Ordinance to ensure regulatory
compliance. Erosion Control staff will assess the percentage of compliant sites versus the
number of NOVs issued for all active construction sites for evaluating prograin
effectiveness.
4. Verify the flow process Erosion Control staff uses for ensuring containment of
construction waste streams. Ensure that no construction waste can enter(directly or
indirectly)the MS4 or waters of the State. Erosion Control staff will submit to DEQ the
total number of construction waste issues that were reported to the responsible state/local
agency.
5. To evaluate complaint response effectiveness, the Erosion Control Division will report to
DEQ the total number of successfully resolved illicit sedimentation discharge/release
claims, which are tracked through the city's Citizen Service Request system.
6. Erosion Control staff will report the total number of views from the Erosion Control
Division's website, as an indicator of public interest.

12.1(a) Post-Construction Storm Water Management Program: The Stormwater Division oversees
and enforces the city's post-construction stormwater management program. The City of
Winston-Salem has supplemented previous water supply watershed regulations with current
post-construction regulations for Class `C' waters to address stormwater runoff from new and
re-developed sites. The current Post Construction Stormwater Management ordinance was
adopted by the City Council on September 19, 2008, and this ordinance applies to all
development within our jurisdictional area(municipal boundary). The City's Post-construction
Ordinance can be located at hns://library.municode.com/ne/winston-
Icodes/code of ordinances?nodeId=PTIIICOOR CH75STMA ARTIVPOCOST.
12.1(b) Strategies,which include SCM's Appropriate for the MS4:
Programs with development/redevelopment draining to Nutrient Sensitive waters:
Drainage from the City of Winston-Salem ultimately flows to the Yadkin River, which is the
main tributary for High Rock Lake. High Rock Lake has been classified as nutrient sensitive
and currently has a TMDL in development for Chlorophyll A and turbidity. Currently,
wastewater point sources are being considered for a waste load allocation(WLA)—not
stormwater sources. Structural and non-structural SCMs will be utilized to address the
requirements of 15A NCAC .0126 (10) (e). These SCMs will provide sediment removal, which
ultimately reduces the nutrient inputs to receiving streams. Proper application and storage of
fertilizers is being addressed through a Turf Management Certification,which is administered
by the Stormwater Division and the Forsyth County Cooperative Extension Service in efforts to
reduce nutrient loading to receiving streams.
Fecal Coliform Source Control
The City of Winston-Salem coordinates with the Forsyth County Department of Public Health
to reduce fecal coliform due to failing/or failed septic tank systems. This process requires the
property owner to either connect to the POTW or repair/replace the septic tank system to
effective operations. The City/County Utilities Commission(CCUC)has an extensive capital
improvement program to rehabilitate failing sections of the sewer collection system.
Stormwater staff works closely with the CCUC to resolve sanitary sewer overflows during dry
weather screening activities or received citizen complaints. In addition, the City of Winston-
Salem has an enforceable ordinance that requires pet owners to pick up fecal matter within its
municipal boundaries. Section 6-12 in the City of Winston-Salem's Municode contains the
sanitation requirements for picking up dog feces, which is posted at
hqps://Iibrga.municode.com/lic/winston-
salem/codes/code of ordinances?nodeld=PTIIICOOR CH6ANFO 56-12SAREDO.

12.1(d) Operation and Maintenance Plan: Stormwater staff inspect approved water quantity SCMs
(pre-2008 post-construction ordinance adoption) as well as the Salem Lake Watershed (Water
Supply IV Classification) SCMs on an annual basis. Next, Stormwater staff informs the owners
of record of any deficiencies noted so that they may be addressed. Operation and Maintenance
Agreements are required to be approved, recorded and implemented for all of the developments
located within the Salem Lake Watershed area that require SCM(s) and the owners of such
SCMs are bound to the terms of that agreement.
The City currently has a spreadsheet that tracks all of the developments and redevelopments that
have been submitted to the Stormwater Division for review and compliance with the Post
Construction Stormwater Management ordinance. This spreadsheet includes a list of the
development names, whether or not they are exempt from the ordinance and if exempt an
explanation of why so, and if they are not exempt a description of what provisions of the
ordinance they had to meet as in water quality-..(low or high density), or water quantity, or
both. This spreadsheet contains pertinent information, such as project submittal,review notes,
date of permit issuance with corresponding number,the owners contact information of the
stormwater management system, what developments we are currently still waiting on for as-
built records to be submitted, what developments have submitted as-builts and hence are subject
to submitting annual inspection and maintenance records, etc., so that Stormwater staff can
efficiently check or reference any development and its criteria that may have been permitted,
since the ordinance was adopted. The City also maintains "hard" files for all projects listed in
this spreadsheet.
SCMs, within the City limits jurisdiction and approved after the adoption of the post-
construction ordinance, must have an Operation and Maintenance Agreement recorded as part
of the post construction permit process that is binding on the SCM owner. The responsibility of
SCM inspection and maintenance is placed on the designated SCM owner, or Homeowners
Association/Property Owners Association, as applicable,who has signed the recorded Operation
and Maintenance Agreement. The requirements for such inspections and maintenance are
outlined in an Operation and Maintenance Manual that forms part of the overall Operation and
Maintenance Agreement. Beginning after the certification of the as-built drawings for a
permitted stormwater management system, the system must be inspected per the frequency
described in this agreement by a suitably qualified professional on behalf of the owner. The
owner must keep all records of these inspections and any maintenance activities that may have
been necessary and submit these records to the Stormwater Director for review on an annual
basis. The Stormwater Director or his designee may carry out his own inspection to validate
such submitted records.
All structural SCMs approved in accordance with the Post-Construction Stormwater
Management ordinance must have a financial surety that meets the requirements of the
ordinance provisions, in force prior to permit issuance. For a developer who wants to remain
the party responsible in perpetuity for the long term Operation and Maintenance of the system,
the surety shall equal four percent of the estimated construction cost of the Stormwater
management system, verified by submittal of a sealed engineers estimate. This surety is held in
a City maintained account and is non-refundable. The developer may apply for a loan from this
account if needed to address system deficiencies. For SCMs that are to be owned and operated
by a HOA or POA, then the surety that is required is in the form of an escrow account and
escrow agreement. The developer establishes an escrow account at the time of permitting and
deposits 15 percent of the estimated construction cost of the stormwater management system
35

2. Stormwater staff will inspect the water quality SCMs located within the Salem Lake
Watershed, which were approved under the provisions of the Salem Lake Watershed
ordinance. Inspection results will be disclosed to DEQ in the FY 2022-2023 Annual
Report.
3. Consult the City Attorney's Office concerning the potential to create a preliminary flow-
process for executing municipal-owned SCM Operation and Maintenance Agreements and
maintenance responsibilities. Once finalized,the City's SCM Manual for municipal
operations will be finished by the Stormwater Engineer. A status update for the task item
will be provided to DEQ in the FY 2022-2023 Annual Report.
4. Identify privately-owned SCMs, which includes as-builts, annual 'inspection records,
maintenance records, etc. to gain compliance with applicable ordinance requirements
within the municipal boundaries.
5. Implement an annual inspection SOP for municipal-owned SCMs that were installed after
2008. Once inspected,the stormwater capital improvement project list will be updated,
encumber funding, and release Requestfor Proposals to maintain or repair municipal-
owned SCMs. Stormwater staff will need to seek Council approval to obtain the funding
to carry out these activities. A status update for the task item will be provided to DEQ in
the FY 2022-2023 Annual Report.
6. The Stormwater Division will review and permit applicable development plans that
require a Post Construction Stormwater Management permit to be issued. This will
include reviewing development plans for compliance with the water quality provisions of
the ordinance that may be either: (a) low density developments, or(b)high density
developments that require structural SCMs. These plans and if needed, SCMs, will be
assessed for compliance with the City's Stormwater quantity ordinance provisions.
Stormwater staff will also ensure they review all other development plans that may be
exempt from the ordinance provisions to confirm any or all exemptions and keep a record
of all such exemptions on file.
7. Stormwater staff will continue to maintain an internal spreadsheet of all submitted
developments for review, exempted, or permit issuance. This spreadsheet shall continue
to contain information such as when was a project permitted, what is the permit number,
what is applicable to a particular development--i.e. is it low density development in terms
of water quality or a high density development and if it was a high density development,
what and how many, types of SCMs were permitted, so that an accurate count of all SCMs
permitted throughout our jurisdiction since the adoption of the ordinance can be gathered
if needed. In addition, this spreadsheet should continue to record if a development had to
meet the water quantity requirements of the ordinance and if so, were SCMs provided.
Conversely, if the developer proves that no adverse impact downstream exists, then no
management is required for water quantity.
8. The Stormwater Division will assess how many SCM owners comply with their Operation
and Maintenance responsibilities as regards inspecting and maintaining their systems and
how many of the owners submit their annual compliance reports to the Stormwater

13.1(a) Inventory of Municipal Facilities and Operations: In 2020, the Stormwater Division
` performed an inclusive assessment of municipal facilities/operations that have a significant
potential for generating polluted stormwater runoff. Subsequently, staff prioritized these
municipal operations for S WPPP creation and implementation due to the magnitude and nature
of activities that each municipal operation provides to the public. Since that time, the
Stormwater Division provides professional services to City entities to create and implement
BMPs for mitigating or eliminating exposure of pollutants to stormwater runoff. The following
tables provide an overview of the City's progression in reducing stormwater pollution from
municipal operations, as of October 11, 2021.

13.1(c) Site Pollution Prevention Plans for Municipal Facilities and Operations: The Stormwater
Division has identified 81 municipal facilities/operations that have the significant potential for
generating polluted stormwater runoff. As of October 2021, 61 municipal facilities/operations
have implemented Stormwater pollution prevention plans (SPPPs)to remove pollutant exposure
to stormwater runoff(Tables 13.2 and 13.3). 20 municipal facilities/operations have been
designated for site pollution assessments/inspections with SWPPP creation and implementation,
if needed (Table 13.4). The Lowery Street Complex will be evaluated for vehicle-washing
BMPs during the coming permit years. (G:lIndustrial Inspection&Municipal
Goodho_u..sekeepinglMGH&PP ProgramlMunicipal FacilitieslMaster Munici ap 1 xlsx)
13.1(d) Spill Response Procedures for Municipal Facilities and Operations: For municipally
owned facilities that are not required to apply for a NPDES Stormwater permit, an abbreviated
SWPPP has been created and implemented by City staff. A key component of this abbreviated
SWPPP is spill prevention and response plan and procedures that are site-specific. SPPPs
include site maps, facility inspections, GH and PM schedule, and SPPP certification. All SPPPs
have site maps, facility inspections, good housekeeping and preventive maintenance schedules,
and a SPPP certification statement. Each municipal operation/facility performs spill response
training on an annual basis. Table 13.3 contains a list of municipal facilities/operations that
have implemented an abbreviated SPPP.
13.1(e) Prevent or Minimize Contamination of Stormwater Runoff from all areas used for Vehicle
and Equipment Cleaning: Upon inspection of each municipal facility or operation, structural
and nonstructural BMPs are recommended for implementation. Stormwater staff promotes
vehicle/equipment washing at the Lowery Street Complex. These washing bays discharge into
an oil and water separator, which is connected into the sanitary sewer. Parking lots for
abandoned vehicles will be evaluated for installation of an oil and water separator. If BMPs
cannot be installed, the vehicle-washing activities will be performed in accordance with NPDES
requirements; selected BMPs will be incorporated into an abbreviated SWPPP to reflect on-site
practices and measures.
13.1 (f) Streets,Roads, and Public Parking Lots Maintenance: The Stormwater Division has
worked in collaborative efforts with Winston-Salem Transit Authority and Winston-Salem
Department of Transportation in order to identify pollutant-laden stormwater runoff from public
streets, roads, and parking lots. Selected BMPs for implementation include increased street
sweeping, enhanced MS4 trash and sediment removal, issuance of condensed spill response
plans and procedures for hydrocarbon releases and implementing a maintenance program for
existing stormwater control measures, which receive inputs from public streets and roads.
13.1(g) Inspection and Maintenance (I&M) for Municipally-owned or Maintained Stormwater
Control Measures (SCMs) and the Storm Sewer System: City Yard Field Operations has
developed and implemented a comprehensive operation and maintenance (O&M)program for
structural BMPs as well as the MS4. This O&M Program includes (but not limited to)these
activities:
43

addition, the Stormwater Inspector will ensure that the municipal operation will have the
proper spill kits and proper contact information on site for elimination and mitigations of
future spills.
5. Continue to have new City employees view the stormwater orientation video and receive a
copy of the handbook, Stormwater Runoff: Municipal Good Housekeeping and Pollution
Prevention. This will serve as a foundation to educate newly hired city employees. The
Stormwater Division will report the total number of city employees that were trained in
proper MGH& PP practices to DEQ. In addition, the Stormwater Inspector and Senior
Community Educator will continue to perform the annual refresher training for targeted
city employees, which is based on a priority ranking. Priority rankings are based on the
last time a facility was trained and or the last time a major spill has occurred.
6. The City will provide funding to 3RC, a facility that collects, disposes, and/or recycles
household hazardous materials in the city of Winston-Salem. The Stormwater Division
will report the total quantity of recycled household hazardous waste to DEQ.
7. The Sanitation Division will collect and compost leaves and vegetative material. The
Stormwater Division will report the total quantity of recycled vegetative matter to DEQ.
S. City Yard Field Operations will continue to remove and dispose of trash and debris from
the MS4. The Stormwater Division will report the total number of inspected and cleaned
MS4 structures. In addition, the Stormwater Division will report the total tonnage of
disposed material.
9. The Sanitation Division will continue to perform streets sweeping activities within the
municipal limits with increased efforts directed to the Downtown business core. The
Stormwater Division will report the total number of linear miles of swept roads/streets to
DEQ.
10. Evaluate the remaining municipal facilities listed in Table 13.4 for potential creation of
full or abbreviated SWPPPs. Stormwater staff will create a priority ranking of municipal
facilities to be inspected. Next, each municipal facility will be assigned a future
inspection month and year—this task item was completed in October 2021. For FY 2022-
2023,the Field Operations Director will attempt to procure budgetary funding for SPPP
creation of identified municipal operations/facilities.
11. Perform inspections of municipal-owned facilities/operations with existing stormwater
pollution prevention plans, but have not been inspected within the past five years.
Stormwater staff should be able to inspect two municipal facilities/operations for FY
2022-2023.

Best Management Practices for the Program to Monitor and Evaluate Stormwatcr Discharges to
Municipal Systems:
14.1(a) Maintain an Inventory of Industrial Sites: A complete list has been created by the
Stormwater Division. This list consists of industrial facilities that are permitted as defined by
40 CFR 122.26, SARA Title III, hazardous waste facilities, or identified as having or had an
illicit discharge. The Stormwater Division updated this master list on October 11, 2021;
updating will occur semiannually. All data will be stored digitally in our database and will be
updated semiannually to maintain the most current inventory. This information can be located at
G:llndustrial Inspection& Municipal Goodhousekeeping\Indust_In.spectlCity Industrial
InformationlIndustrial Master.xlsx.
14.1(b) Inspection Program: Our current techniques are based upon revised 2006 EPA inspection
methods, which include observations of effectiveness of nonstructural and structural BMPs,the
facility's stormwater collection system and stormwater discharge outfalls, site maps, and
validation of written SPPP information to actual field observations.
The City of Winston-Salem has prioritized industrial facilities within its municipal limits to be
inspected. The Stormwater Division used the following sources to generate the list:
I. -EPA's Envirofacts Database for Toxic Release Inventory (SARA Title III) and RCRA
(hazardous waste treatment, disposal, and recovery) facilities (updated semiannually)
2. NC Department of Energy, Mineral and Land Resources Database (General and Individual
Permitted industrial facilities, as per 40 CFR 122.26) (updated semiannually)
3. The City of Winston-Salem Facilities' Database (municipal operations/facilities that are
permitted under 40 CFR 122.26) (updated semiannually, or as needed)
4. Illicit Discharge Reports (updated as needed and after each occurrence)
When combining the above-mentioned databases, facilities that appeared multiple times due to
their industrial activities and governmental regulations were ranked. As a result,the
Stormwater Division assigned these industrial facilities with a `high-priority' ranking due to the
elevated probability of significant adverse impact to surface waters. The Stormwater Inspector
will target these facilities for inspections; our goal is to inspect every permitted facility once
every five years.
14.1(c) Evaluate Industrial Facilities discharging stormwater to the City's MS4: During the SPPP
review, Stormwater staff evaluates first flush data regarding benchmark values from the NPDES
permit to determine to status before arrival. Once onsite for an inspection, a visual field
observation of the stormwater collection system, current and past conditions of stormwater
discharge outfalls (by means of qualitative monitoring records), and effectiveness of
nonstructural and structural BMPs are observed. If needed, Stormwater staff will request copies
of each sampling event to monitor results based upon the status of the permitted facility.
Stormwater staff will update the master list to identify if the permitted facility is located within
a TMDL watershed and/or discharges the TMDL pollutant of concern. The Stormwater
Division maintains a good working relationship with NC DEQ, Winston-Salem Regional
Office. A copy of every completed inspection and re-inspection form must be forwarded to
Levi Hiatt, Assistant Regional Engineer, who handles stormwater related duties for the
Winston-Salem Regional Office (WSRO) or the current Assistant Regional Engineer at the time
of submittal.

16.1(c) Assessment of Available TMDL Monitoring Data: The Stormwater Division performed a
programmatic review of its TMDL Sampling Plan in September 2019. One of the salient points
of the review included the lack of a substantial fecal coliform data population. As a result, the
Stormwater Division designated 22 in-stream monitoring locations throughout Salem, Peters,
and Brushy Fork Watersheds. Stormwater staff collects water quality samples on a quarterly
basis; as more data becomes available, Stormwater staff will perform basic statistical analyses
to rank the stream segments by the level of impairment(i.e., the higher the geometric mean at
the sampling location, the more level of pollutant loading). Stormwater staff calculated the
geometric mean (expressed in units of cfu/100 mL) for the 22 TMDL sites and created a priority
ranking, based upon the most polluted stream segments. As more data becomes available,
Stormwater staff will perform basic statistical analyses to rank the stream segments by the level
of impairment(i.e.,the higher the geometric mean at the sampling location,the increased level
of pollutant loading).
16.1(d) TMDL Monitoring Program: On a quarterly basis, Stormwater staff collects instantaneous
water quality parameters {dissolved oxygen- concentration and percent saturation, total
dissolved solids, conductivity,temperature,pH, nitrate, and ammonia) as well as certified
laboratory results of fecal coliforms at 22 strategic locations throughout Brushy Fork Creek,
Peters Creek, and Salem Creek Watersheds. By collecting a large population of samples,
Stormwater staff will be able to rank impaired stream segments by fecal coliform
concentrations. Once stream segments are ranked, staff will systemically sample and identify
the most impaired outfalls or subbasins for the potential of installing stormwater control
measures. The city collects samples in both dry and wet weather conditions, since the state
collected and analyzed fecal coliforms during these conditions for TMDL development. This
methodology will allow Stormwater staff to perform comparative analyses for evaluating
pollutant loading.
16.1(e) Additional Measures: The city of Winston-Salem anticipates the implementation of numerous
nonstructural BMPs in order to expand current pollutant reduction strategies within the Salem
Creek Watersheds. By expanding current BMP strategies to the maximum extent practical, the
City hopes to benefit from synergic pollutant reductions within the targeted watershed. The
following matrix presents expanded measures (with corresponding explanations)to reduce fecal
coliform loadings within the Salem Creek Watershed:

�.16.2 Salem Creek Total Maximum Daily Load (TMDL) Annual Report Task Items for FY 2022-
2023:
1. Record the total distance (in linear feet) of restored drainage ditches within the Salem Creek
Watershed (and contributing tributaries) for total suspended solid reduction.
2. Review the city's street sweeping operations and explore that potential to increase the area(or
distance) swept within the Downtown Business District as well as additional municipal facilities.
Stormwater staff will report the total number of linear miles swept to DEQ.
3. During TMDL sampling, instantaneous results of ammonia, pH, and dissolved oxygen percent
saturation, dissolved oxygen concentration,temperature, conductivity,total dissolved solids, and
nitrate are collected. This data will be provided for DEQ. This information is located at
G:1Teehn Projects_FileslWater SamglinglStormwater Sampling„DatabaseslCurrent
4. Perform IDDE response procedures within the impaired Salem, Brushy Fork, and Peters Creek
Watersheds to permanently eliminate pollutant sources, remove illicit connections, and to identify
sanitary sewer overflows. The Stormwater Division will report the total number of linear feet of
walked streams within the Salem Creek Watershed{and contributing tributaries)to DEQ. In
addition, Stormwater will report the total number of discovered sanitary sewer overflows, the
number of illicit discharge responses and corresponding issued NOVs within the Salem Creek
Watershed to DEQ.
5. Submit a spreadsheet data of fecal coliform concentrations from all 22 TMDL sampling locations
as well as a priority ranking of impaired stream segments, based on annual geometric mean,to
DEQ.
6. Submit all completed programmatic tasks and workload data that bolster pollutant reduction
activities within the Salem Creek Watershed (and contributing tributaries)to DEQ.
7. Status updates of proposed/completed SCM capital improvement projects/nonstructural BMPs
within the Salem Creek Watershed (and contributing tributaries)to DEQ.
S. Stormwater staff calculated the geometric mean(expressed in units of efu/100 mL) for the 13
fixed interval sampling sites, based upon the most polluted stream segments for fecal coliforms.
The top three polluted stream segments (during dry weather conditions) are Mill Creek at
Shattalon Drive (4,970), Peters Creek Peters Creek at the Antique Dealership (3,054), and Brushy
Fork Creek(890) at Reynolds Park Road. No water samples were obtained during wet weather
conditions due to an overabundance of divisional workload. When evaluating concentrations for
the past two permit years, Stormwater staff observed that two of the three sites, Peters Creek at
the Antique Dealership and Brushy Fork Creek at Reynolds Park Road are the most polluted
for fecal coliforms (during dry weather conditions). As of September 2022, HDR Engineering is
performing stream reconnaissance activities of Peters Creek—from Hanes Park to the Antique
Dealership. Once Stormwater staff receives reconnaissance survey results, staff will review and
evaluate all fecal coliform sources for appropriate mitigation measures. For PY 2022-2023,
Stormwater staff will focus investigative efforts within Brushy Fork Creek from Old
Greensboro Road to Reynolds Park Road.
