PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which the City of
Conover 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 City of Conover 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 NCS000488, as issued by
NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated
by the City of Conover and located within the corporate limits of the City of Conover.
In preparing this SWMP, the City of Conover 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.

3.2 Existing MS4 Mapping
The current MS4 mapping includes outfalls located within the City of Conover. In the future, the City will be adding the
following elements to the map: stormwater conveyances, flow directions, and receiving streams. This is addressed in
development, funding, and maintenance in Permit Reference 3.4.1 BMP 19.
The City of Conover has a historic count of 153 outfalls per the GIS layer created; however it is not certain that all of
these are major per the definition provided below. The City will be verifying all elements, as mentioned above, in the
completion of BMP 19.B.1 addresses the verification of the existing data, and BMP 19.B.3-4 addresses the updating of the
existing map, as well as, adding additional infrastructure as it comes in.
Table 1: Summary of MS4 Mapping
Percent of MS4 Area Mapped 90 %
No. of Major Outfalls* Mapped 153 Total
*An outfall is a point where the MS4 discharges from a pipe or other conveyance (e.g. a ditch) directly into surface
waters. Major outfalls are required to be mapped to meet permit requirements. A major outfall is a 36-inch diameter
pipe or discharge from a drainage area > 50-acres; and for industrial zoned areas a 12-inch diameter pipe or a drainage
area > 2-acres.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the City of Conover as summarized in
Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The
City of Conover has evaluated residential and charity car washing for possible significant water quality impacts. Street
cleaning is performed with dry street sweeping process; however construction sites occasionally with clean the streets
with potable water as directed by NCDOT and Erosion Control requirements.
The Division has not required that other non-stormwater flows be specifically controlled by the City of Conover.
Wash water associated with car washing that does not contain detergents/surfactants or does not discharge directly into the
MS4 is considered incidental. However, these types of non-stormwater discharges that do contain detergents/surfactants
have been evaluated by the City of Conover to determine whether they may significantly impact water quality. The City
of Conover will address the possibility of the below mentioned water quality impacts through public education and good
housekeeping, as outlined in Part 5 BMP 3-8 and Part 10 BMP 45-47, 49, 52-54, 56, 57 and 61 with focusing on good
housekeeping training and practices.

3.9 Target Pollutants and Sources
In addition to those target pollutants identified above, the City of Conover is aware of other significant water quality
issues within the permitted MS4 area. Target pollutants as listed below are contributors of the stream impairment. TMDL
measures have been put in place to improve water quality.
Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWMP, the likely
activities/sources/targeted audiences attributed to each pollutant, and identifies the associated SWMP program(s) that
address the target pollutants. In addition, the City of Conover has observed and evaluated: schools, homeowners,
businesses, industrial sites, farming, construction activities, and public employees as target audiences that are likely to
have significant stormwater impacts. Within the table and list below the following target pollutants have been found to be
concerns within the community.
Litter: Roadside litter is an ongoing issue for the City. This litter poses a threat to both our water bodies and the MS4
infrastructure, as the litter can create clogs and backups that damage the pipelines/conveyances that lead back to the
stream. Some litter even poses a threat to groundwater if chemical leaching or breakdown of components into heavy
metals occurs due to weathering of the litter. Most litter is found on the side of major roads, around school facilities, and
certain businesses.
Sediment: Sediment buildup is largely attributed to mismanaged construction sites with fallen or incorrectly installed
sediment fences. Erosion control fences failing or being improperly maintained. This has led to sediment buildup near
storm drains, onto down slope private properties, and in some cases causing water to build up in nearby properties as the
sediment is limiting the drains ability to remove runoff. In all cases the city has responded and had the issue solved, but
even being down for a short time can have significant effects. Erosion control fences are required for sediment control
permits during construction by the DEQ throughout the entire construction process.
Gray Water: In the past a few residents have been found with washing machines straight-piped out of their homes by
using water hoses exiting windows. Homes are to be connected to the appropriate sewer system. This proves to be a
source of detergents/soaps entering our storm drains in residential neighborhoods. In addition: residential, charity, and
municipal car washes allow for soaps or waxes to enter the storm drain when vehicles are not being cleaned in the correct
areas (such as vegetated patches or in areas that do not have storm drains). This allows for toxic contaminants to enter
waterways via the storm drain system.
DRAFT NCS000488 SWMP
City of Conover
June 11, 2020
Page 10
Fats Oils and Grease: Can become an issue when grease traps are not appropriately maintained. This has led to cases of
the restaurants allowing the grease to drip onto nearby impermeable surface – which would eventually lead to water
quality issues. Overflow from a lack of maintenance or throwing out the grease with general waste contributes to this
problem. This is a health violation since the grease poses a physical risk, but it also can impair water bodies with an influx
of water insoluble grease going down the storm drain. In all cases, code enforcement has responded and the issues have
been remedied.
Chemicals: Industrial sites housing totes/containers of unknown/unmarked chemicals can lead to potential soil and water
contamination, and/or incorrect spill cleanup procedure. Totes/containers are to be correctly stored in a way to minimize
risk to the water bodies from seepage, damage to the containers, or spills. Any reports Code enforcement has responded.
Animal Operations: agricultural runoff often caries excess fertilizer which will cause eutrophication in streams
with its cascading effects. Within the Catawba River Basin roughly 46 streams are/were impacted by fecal
coliform, with 10 being listed on the 303(d) list. As this is a non-point source pollutant it is hard to locate the
exact source of this runoff, however in much of the watershed there is agricultural zoning that makes it likely
for these types of impairments to occur. The City does allow Shetland horses (sub 125 lbs. and under 34 inches
at shoulder), which has a small potential for increasing nutrient load from horse waste.
Underground storage tanks: Storage devices installed below ground can contain gasoline, fuels such as propane,
industrial chemicals/oils, and most often human waste (fecal coliform) in areas not directly connected to the sanitary
sewer. Any underground storage tank must be well maintained/monitored, and correctly installed due to the risk of them
leaking. The leaks can cause whatever chemical the tank is storing to leak into the ground, harming the soil,
groundwater/water table, and even surface waters as they are being fed from groundwater. If a fuel or industrial chemical
tank is leaking, the chemical will leach into the soil – leading to toxic soil, contaminated groundwater, and possibly
impairing a stream/water body. Conover has worked with EPA Brownfield Assessment grants prior to determine the level
of contamination (if any) from former industrial sites.
Some areas of the City still have homes that utilize septic tanks, but the majority of properties in the City are served by
sanitary sewer. If a septic tank is leaking, it can overwhelm the natural processes of the soil (infiltration) leading to
nutrient overload in streams fed by groundwater, or allowing pathogens to enter, increasing the risk of disease. The 10
303(d) fecal coliform impaired streams listed can have some attribution to septic tank leakage. When septic tank failure is
noted, the home is required to connect to sanitary sewer where available.
Illicit discharges: Originate from a variety of sources, with an equally varied number of effects dependent on the
chemical that is released. Typically, illicit discharges come from businesses, residents or municipal facilities who dump
chemicals into storm drains either incidentally due to a lack of IDDE education or general carelessness. These chemicals
can vary greatly, and can include grease, oils, chemicals, cleaning solutions, paints, metals, etc. This is a recognized
problem as we have several 303(d) streams impaired from causes related to substances or attributions given to unclean
discharges into the streams - in addition to reports generated by the municipality. Many of the 303(d) benthos impaired
streams can be attributed to IDDE issues, but they are often from inexact/non-point sources that are attributed to illicit
discharges
Illegal dumping: Waste dumped randomly in non-permitted dumping areas, can cause a variety of problems. For
example, citizens dumping televisions on the side of the road to avoid dumping fees, which allows for the metals or
chemicals inside TVs to leach out as stormwater passes it (mercury, lead, and other metals). It can be a case of businesses
dumping waste in watershed areas where runoff passes through the waste, either carrying it, or residuals of the waste into
water bodies. It can also be a case of graders dumping sediment into areas without the correct allowances/precautions. The
debris and chemicals accumulate over time and lead to chemical impairments, pH issues, turbidity impairments, or debris
entering the stream/MS4 system. The City provides municipal residential solid waste pick-up weekly to all City residents.
DRAFT NCS000488 SWMP
City of Conover
June 11, 2020
Page 11
Improper disposal of waste: Allows chemicals, or difficult to manage waste, to enter the environment in ways that may
be hard to track. For example; not giving a car battery to the correct waste management facility can allow for battery acid
and lead to enter the soil which drains/collects in the groundwater. These types of problems have been noticed by
municipal waste managers and can be difficult to track since the improperly disposed waste is mixed in with the standard
refuse. Other examples include grease going down sinks clogging sanitary MS4 systems, chemicals from batteries
leaching into the groundwater, oil from oil changes not going to the correct facility, etc.
While some of the target audiences are not as prominently found within the City, it is still important to educate because
they can be likely sources of non-point pollution through uninformed management practices.

4.2 Program Funding and Budget
In accordance with the issued permit, the City of Conover 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 administration and compliance fee, which is billed by DEQ annually.
The City of Conover’s Environmental Coordinator/Construction manager’s salary one-third is covered by stormwater and
two-thirds by water and waste water fees. To help cover support expenses Public Works allocated 180,000 from General
Fund and Utility Monies. Leaf collection is complete by City Sanitation Staff and temporary contract workers. During the
non-leaf season Grounds oversees the litter sweep, with $21,500 allocated.
The City of Conover has a two-year contract (which will need to be modified, adopted, and signed every two years) with
Western Piedmont Council of Governments for the following support services: Public Education and Outreach Program,
Public Involvement and Participation Program, Illicit Discharge Detection and Elimination Program, Post-Construction
Site Runoff Control Program, and Pollution Prevention and Good Housekeeping Programs. The current contract amount
for the 2-year period (years 1 and 2 of the NPDES permit cycle) is $53,354.00 of general funds being used. The City will
be responsible for the cost of the annual NPDES permit renewal, which is to be paid to the state. Any fees charged to the
development community for BMP Inspections, Plan Review, and other associated fees will be used to help offset cost.
DRAFT NCS000488 SWMP
City of Conover
June 11, 2020
Page 15
The City may determine that stormwater utility fees should be implemented; these fees would be collected by the City
through utility bills.
Should the City of Conover choose not to renew the existing two-year contract, prior to the last month, a revision to the
existing NPDES permit and Stormwater Management Plan would need to occur. The City of Conover would be required
to renew the two-year contract, in years 2022 and 2024, to fully carry out the 5 year NPDES permit cycle.
4.3 Shared Responsibility
The City of Conover will be responsibility, with WPCOG (referred to as entity) providing support service, to implement
the following minimum control measures, which are as stringent as the corresponding NPDES MS4 Permit requirement.
The City of Conover remains responsible for compliance if the other entities fail to perform the permit obligation and both
may be subject to enforcement action, if neither the City of Conover, nor the other entities fully perform the permit
obligation. Table 9 below summarizes individual responsibilities for each program.

4.5 Measurable Goals for Program Administration
In response to the DEQ MS4 Audit completed in 2018 for the City of Conover - Program Implementation, Documentation
& Assessment (II.A2, II.A.3, II.A.4, II.A.7, III.A., III.B., IV.B. ) the following changes are being implemented.
Per BMP 1 the SWMP will be reviewed on an annual basis to determine if any updates need to occur. All documents
associated to the Stormwater program will be accessible online, either via the City of Conover website or the Western
Piedmont Council of Governments Stormwater Partnership webpage (reference BMP 14 and 30). Documentation of all
actions related to stormwater activities (as mentioned below) will be recorded, so staff can track and evaluate the
effectiveness of each program component.
The City of Conover will manage and report the following Best Management Practices (BMPs) for the administration of
the Stormwater Management Program using Public Education & Outreach, Public Involvement & Participation, Illicit
Discharge Detection & Elimination, Post-Construction Site Runoff Control, and Pollution Prevention & Good
Housekeeping.

PART 7: ILLICIT DISCHARGE DETECTION AND ELIMINATION PROGRAM
Per the MS4 Inspection Report the City has written procedures for implementing an IDDE Program. To increase efforts
the City will locate priority areas likely to have illicit discharges, conduct routine dry weather outfall inspections, identify
illicit discharges and trace sources, eliminate the source(s) of an illicit discharge, and evaluate and assess the IDDE
Program.
The City has a stormwater ordinance and other regulatory mechanisms that provide the legal authority to prohibit illicit
connections and discharges to the MS4, as well as the authority to apply enforcement to violators of the ordinance. The
documents will be reviewed, and if necessary, updated to maintain the program and enforce IDDE issues effectively.
The City of Conover has approximately half of the MS4 mapping completed; however as development occurs the map
and associated components will be updated accordingly.
In the last permit cycle the City did not conduct dry weather screening or maintain written procedures for dry weather
field activity (II.D.2.d. Dry Weather Flow Program). Within the Stormwater Management Plan a schedule is to be created
to conduct dry weather screening annually. Data such as date screening occurred, location of inspected outfall, and photos
of outfall will be recorded in GIS.
The City of Conover in the past has investigated IDDE complaints; however there is no tracking mechanism for
documenting violations and enforcement actions (II.D.2.j.). Within the new permit cycle, the use of a GIS application to
track and document IDDE cases will be used. This will allow the City to identify priority areas based on historical data.
Further, the City will continue to train municipal staff and the general public to identify illicit discharges and illegal
dumping through the use of educational outreach materials and training opportunities. Educational material will be
available to help educate public employees, businesses, and the general public about hazards associated with illicit
discharges and the improper disposal of waste.
Public complaints of any kind could be submitted to the City through point contact on the webpage. A webpage portal
will be established on the WPCOG website, as well as, linked to on the City website. The portal will be publicized, as
well as, the stormwater hotline phone number, as mentioned in the public education and outreach and public involvement
sections of this plan. A citizen can make a complaint via hotline number or through an email tool on the WPCOG
webpage.
The City of Conover will develop, manage, implement, document, report, and enforce an Illicit Discharge Detection and
Elimination Program which shall, at a minimum, include the following illicit discharge detection and elimination BMPs.
The existing Illicit Discharge Detection and Elimination Program will be expanded in order to implement a complete
program by permit year 5.

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
In accordance with 15A NCAC 02H .0153, the City of Conover 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.

PART 9: POST-CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
The City of Conover SWMP 2013 has policy language for deed restrictions and protective covenants. In the new SWMP
permit cycle the language will also be included in the Stormwater Ordinance. An amendment to the ordinance will allow
the language to have legal significance.
Contracting WPCOG, an inventory of projects will be established (BMP 35.B.1, 2, and 3) for developments within the
municipal limits, this is in response to Permit Citation II.F.2.d, of the latest DEQ MS4 audit (2018). Along with the
inventory list, proactive inspections will be administered by Staff semi-annually and the owner of the privately owned
SCM will be required to have an inspection done by a certified private engineer annually to ensure SCM functionality
(Permit Citation II.F.2.g.). Upon non-compliance, enforcement action will be taken. The City will have a GIS tracking
mechanism to proactively enforce to obtain compliance (II.F.2.i.).
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 City of Conover
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 City of Conover implements the following State post-
construction program requirements, which satisfy the NPDES Phase II MS4 post-construction site runoff control
requirements as Qualifying Alternative Program(s) (QAPs) in the MS4 area(s) where they are implemented.

The City of Conover has a small portion on the east side of the City limits located within a water supply watershed. The
area within the watershed boundaries are required to follow those rules to ensure drinking water quality is being
maintained. This is known as a Qualifying Alternative Program (QAP). The City is also subject to the NPDES Phase II
MS4 post-construction program requirements. These existing requirements will be codified in local ordinance(s) per

PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS
This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the City of Conover
municipal facilities and operations. Pollution prevention and good housekeeping is accomplished through the
implementation of seven required programs, which collectively address the ultimate goal of preventing or reducing
pollutant runoff from municipal operations such as park and open space maintenance, fleet and building maintenance, new
construction and land disturbances, and municipal storm sewer system maintenance.
Pollution prevention and good housekeeping for municipal operations includes the following programs:
1. Municipal Facilities Operation and Maintenance Program (O & M)
2. Spill Response Program
3. MS4 Operation and Maintenance Program
4. Municipal SCM Operation and Maintenance Program
5. Pesticide, Herbicide and Fertilizer Management Program
6. Vehicle and Equipment Cleaning Program
7. Pavement Management Program
The City of Conover will manage, implement and report the pollution prevention and good housekeeping BMPs as
specified in Table 21 below for each required program in response for the MS4 Audit inefficiencies. BMPs 45 and 46 will
require a written inventory of facilities and potential pollutants. Several of the BMPs below address street and parking lot
issues by developing, adopting, and maintaining procedures that focus on pollutant removal in these impervious areas,
along with, Setting schedules and requirements for street/parking lot sweeping (BMP 58), collecting litter/debris (BMP
59), working in collaboration with community outreach program and developing standard spill procedures (BMP 47).
The City of Conover uses a vac-truck to clean the storm sewer conveyance system. An O & M plan had not been created
and maintained at the time of the MS4 DEQ Audit. Permit Reference: 3.7.3, BMP’s 48-51 focus on the training,
inspection, and maintenance of said system.

facility with the potential to
generate stormwater pollution.
These plans will define the
expectations of the facility in
regards to stormwater/MS4
regulations. Each municipal
facility in which this is applicable
will implement an O&M plan.
The implementation of a plan
entails signing a legally binding
document that defines the party
charged with ensuring that the
facility is correctly maintained
and documentation of the
maintenance is adequate. The
documents will also define the
procedures in how the facility will
be maintained to reduce the risk
of stormwater pollution. The
facilities requiring O&M plans
will be inventoried through BMP

and/or store vehicles, washing
procedures will be defined in the
facilities O&M plan.
