Introduction
On July 1, 2005,The North Carolina Division of Water Quality(DWQ) in the Department of
Environmental Quality(DEQ formerly DENR) began issuing Phase II stormwater permits to municipalities
in North Carolina under the National Pollutant Discharge Elimination System Program (NPDES). At the
time,the NPDES Phase II Program was the latest stormwater program stemming from the Federal Clean
Water Act of 1972. Prior to the Phase II program, EPA and NC DEQ had issued NPDES Phase I Stormwater
Permits to Cities larger than 100,000 persons. In North Carolina these cities were Raleigh, Charlotte,
Fayetteville, Durham, Greensboro, and Winston Salem.The Phase II Program included distribution of
Phase II permits to municipalities less than 100,000 residents and began with municipalities within
Municipal Spheres of Influence (MSI)that were greater than 50,000 citizens.

The Phase II stormwater program was created with the intention of improving the quality of the nation's
waterways by reducing the quantity of pollutants that stormwater transports into stormwater systems
and discharges to surface water bodies. The permit require permittees at a minimum to develop,
implement, and enforce a stormwater program designed to reduce the discharge of pollutants from the
municipal separate storm sewer system (MS4) to the maximum extent practicable.
The stormwater program is composed of the following six management measures:
1. Public Education and Outreach
2. Public Involvement and Participation
3. Illicit Discharge Detection and Elimination
4. Construction Site Runoff Controls
5. Post-Construction Site Runoff Controls
6. Pollution Prevention and Good Housekeeping for Municipal
Operations
Each of these measures consists of required Best Management Practices (BMPs), measurable goals for
each BMP and an implementation schedule for the 5 year permit cycle. Additionally, the City of Roxboro
has a Comprehensive Stormwater Management Program and completes annual reporting about the
NPDES Phase II Program. Because the NPDES Program concentrates on water quality it has limited
provisions concerning water quantity and flooding controls.
The City's permit was officially issued in late 2011 and a copy of the permit that is available either
through Josh Johnson, P.E. or through NC Division of Energy, Mineral and Land Resources (NC DEMLR—

NPDES—MS4 Program) - DEQ. The City was audited in May of 2021 and Is currently in the process of
Permit renewal. DEQ is reviewing an updated Comprehensive Stormwater Management Plan that will be
adopted once it is approved by DEQ and the City council.
This Report is intended to complete the Annual Report specifying the City's progression in
implementing the NPDES Permit and Comprehensive Stormwater Management Plan. It is also a staff
review of the items implemented during this fiscal year.
It is intended to give readers a comprehensive idea of the City's full Stormwater Program including
reporting information for the implementation of the Falls Lake Rules as well as the City's current
funding structure.Additional Falls Lake reporting is likely to be needed after the EMC approval of the
City's interim period program.
NPDES Phase II Minimum Control Measures
Each of the 6 Minimum Control Measures (MCM's) has a set of best management practices (BMP's)that
are intended to foster compliance with both the City's Permit and CSWMP.These specific BMP's can be
found in both the Permit and the CSWMP but highlights and specific actions will be noted in the report.
Public Education and Outreach
The City operates a Public Education and Outreach program that is designed to educate the general
public about the need to improve water quality in stormwater.The general objectives are to distribute
education materials to the community and/or to conduct equivalent outreach activities about the
impacts of storm water discharges on surface waters and the steps the public can take to reduce
pollutants in stormwater runoff. These objectives have been further refined to target residents, school
children, local businesses(specifically gas station owners and landscaping companies) and industry
because these groups have the most impact on stormwater pollution prevention.
The education program targets total suspended solids (TSS and sediment) and nutrient loading because
turbidity, sedimentation, and nutrients are the pollutants of concern in downstream waters.
The City has stormwater handouts on display at the Roxboro City Hall.The City's website also maintains
a Stormwater Link: http://www.cityofroxboro.com/government/public-services/engineering-
services/stormwater-administration which has information on the stormwater ordinance.
Roxboro also partners with the Clean Water Education Partnership (CWEP), an education and outreach
organization hosted by the Triangle J Council of Governments(TJCOG). CWEP is a cooperative group
that is funded by 42 communities in North Carolina. It was created in 2001 to provide education and
outreach for MS4 systems. CWEP has a large Mass Media Campaign that includes an educational
website,TV, Radio and Social Media campaigns. Through this resource CWEP is able to bring
stormwater education to a large population in the City of Roxboro and surrounding areas. In 2018 CWEP
hired its first AmeriCorps service member to conduct direct environmental education and outreach with
children and adults in CWEP communities. This program was very successful and continued in 2022.

Public Participation and Involvement
The City has a responsibility to solicit and consider public opinion on all matters, including stormwater
management. Many times this involvement is lacking but the City is often times required to continue to
solicit public involvement.The City of Roxboro is currently in this situation.The City originally involved
the public with a public hearing in 2010 and has attempted to create a stormwater committee but has
not found a receptive audience.The City answers questions from citizens and maintains a
Helpline-City Hall at(336) 599-5658 and has worked with CWEP but continues to struggle to establish
effective Public Participation and Involvement.The City plans to resume Stormwater Public Meetings as
needed.This public meeting will seek input on the stormwater program and will provide both input to
the City as well as education to the citizens.
Illicit Discharge Detection and Elimination
The City of Roxboro has a full Illicit Discharge Detection and Elimination (IDDE) Program.The IDDE
Program is intended to reduce discharges to the stormwater system that are not entirely composed of
stormwater.There are a few permitted discharges and firefighting related discharges that are allowed.
An illicit discharge is typically dirt, soap, pet waste, litter, oil, fertilizer, pesticides, or raw sewage and
often times comes from "generating sites." Generating sites are points of pollution that continue over a
period and are recurring at regular or irregular intervals.
The backbone of the IDDE program is the IDDE Ordinance that the City passed in June 2012 (at the same
time as its Phase II and Falls Lake New Development Ordinances).This ordinance was revised on
February 12,2019. The IDDE ordinance provides permits specific discharges into the MS4 as legal,
provides legal authority to restrict illegal discharges, prohibits illicit connections, provides conditions for
cleaning up and preventing polluted spills, provides for right of entry into property to investigate
prohibited activities, and provides the City with options for enforcing the Ordinance. The IDDE
Ordinance is based on the NC DWQ's Model Ordinance.
The second basis for the IDDE program is the City's MS4 Map.The City's mapping effort is complete.
The map includes the entire MS4 system and provides for easy access to aid in the investigation of illicit
discharges. An investigator with the map could find an illicit discharge and then easily follow the flow of
the discharge upstream until finding a source of the discharge.The map is available for use through GIS
and is printable for non-GIS users.

MS4 Sample Map
The IDDE program also includes dry weather testing of outfalls into the stream system. In the first
permit cycle this is conducted in coordination with the mapping. Outfalls that have dry weather flows
are reported and investigated.
In 2022 the City of Roxboro's had no private storm drain failure overflows. no illicit connections, no
rerouted wastewater to stormwater connections.Two cases of illegal dumping were found and reported
by the public works superintendent. New no dumping signs were added.
The City's Capital Improvement Budget for 2022-2023 included funding totaling$81.6 million in future
repairs to limit sanitary sewer overflows.
City Staff are trained on an annual basis as needed to identify illicit discharges and the reporting process
for these discharges. This training is combined with the Pollution Prevention and Good Housekeeping
training of public works, utilities, and some administrative staff. A possible future improvement would
be virtual trainings and/or including personnel from other departments including fire and police
personnel. Virtual training of new hires might also be a good addition.
Construction Site Runoff Controls
The City of Roxboro delegates the Construction Site Runoff Controls to the NC DEQ Division of Land
Quality.The City of Roxboro does not have a delegated erosion control program but does make sure
that plans it approves that will disturb greater than 1.0 acres of land apply for, and receive, and erosion
control plan.The City of Roxboro also has the ability to call NC DEQ to report known sedimentation
Page 8 of 16

City of Roxboro Stormwater Annual Report
2022-2023
issues. A possible improvement could be NC DEQ's responsiveness to City generated complaints, which
has been less than effective in the past.
Post Construction Site Runoff Controls
The City of Roxboro has a typical NPDES Phase II Post Construction Program.This includes a Post
Construction Ordinance, administrative forms that support it, and a review process. The Post
Construction Program is intended to treat two different watersheds.The northern portion of Roxboro is
in the Roanoke River Watershed and has only typical NPDES Phase II Stormwater Controls.The southern
portion of the City drains to the Neuse River and is within the Falls Lake Watershed.The Falls Lake
Watershed is subject to both the Water Supply Watershed restrictions and the Falls Lake Rules
restrictions.The below table further explains the differences in the two watersheds.

*Projects that impact the 50' riparian buffers on USGS Streams within the Falls Lake Watershed will be
required to obtain approval from NC DWQ unless a separate buffer program is adopted by the City of
Roxboro.
The City passed its New Development Ordinance in June 2012 (Revised Feb. 12,2019)and the ordinance
contains language explaining the different watersheds and establishing the different standards.The
City's ordinance also allows for the Stormwater Administrator to require peak flow matching for the 100
year—24 hour storm.

Roxboro River Basin Map
When a project is submitted to the City it goes through the City Planning Department. During the review
process, Public Services Director Ken Griffin. reviews the project from both a stormwater and a utility
perspective. At that point review comments are made about the project and addressed.After approval
of the project,the owner is required to complete an Operation and Maintenance Agreement for the
stormwater control measures.This O&M agreement is then recorded with the register of deeds so that
it can reviewed at a later point in time.
In 2023 the City of Roxboro conducted 5 plan reviews, all of which triggered the Stormwater Ordinance.
The City of Roxboro requires as-builts and annual inspection reports from new stormwater control
measures (SCM).
Pollution Prevention and Good Housekeeping
Pollution Prevention is an overall goal of the City's stormwater management plan and Good
Housekeeping is a key to that goal. Municipalities, in general, conduct many activities that can pose a
threat to water quality. Municipal facilities are the primary potential source of contamination but with
good housekeeping habits this potential can be reduced or eliminated. The City attempts to minimize
stormwater pollution from municipal operations by complying with best management plans for each
City facility.The BMP's are written into a City Facilities O&M Plan that is intended to reduce or eliminate
stormwater exposure of oil, grease, pesticides, herbicides,fertilizers, sediment, and other materials

2022-2023
used by the City. Each of the City facilities is inspected annually and any issues are noted,written into
the Facility O&M Plan, and discussed with the facility supervisor.
The City operates a City Hall/Fire Department, Police Station, 2 Fire Substation, Public Services Facility,
Water Treatment Plant,Wastewater Treatment Plant, and an Old Public Works Facility. Each of these
facilities is inspected annually and any new facilities will be added to the inspection list.

Salt Storage at Public Works
City staff with the greatest exposure to stormwater are trained on PPGH once annually.The training is
combined with illicit discharge detection and elimination training.The PPGH portion of the training
concentrates on good housekeeping functions.This often includes identification of bad habits that can
take place and how to fix the situation to reduce the risk of pollution to stormwater.
No salt or salt brine was used during inclement weather in 2022-23. The City recycled 342 gallons of
used oil with Noble Oil Services in 2022-23.
The City of Roxboro sweeps the entire cities streets on a weekly basis,which they estimate to be 800
miles a month.The City's sweeping operation picked up 960 yds. in 2022-23. Culverts and storm drains
are cleaned by jet truck and hand as needed.The City contracts out outfall cleaning.

The City maintains 4 pet waste signs or stations.
Impaired Waters and Total Maximum Daily Loads (TMDL)
The City of Roxboro discharges to one impaired stream in the Roanoke River Basin and a different
portion of the City is in the Falls Lake Watershed.The impaired stream is Marlow Creek. Marlowe Creek
(22-58-12-6b) is impaired for aquatic life.The Falls Lake Watershed is covered later in this report.
Falls Lake Rules
A portion of the City of Roxboro is within the Falls Lake Watershed and is subject to the Falls Lake
Nutrient Strategy.The Falls Lake Rules were adopted in January 2011 to restore water quality in the lake
by reducing the amount of pollution entering upstream. The rules are a staged nutrient management
strategy designed to reduce nutrient discharges to the lake from various sources, including stormwater
runoff from new and existing development,wastewater treatment plants and agriculture. The following
rules are often referred to as the Falls Lake Rules.:
15A NCAC 02B .0275 - Purpose and Scope
15A NCAC 02B .0276- Definitions
15A NCAC 02B .0277-Stormwater Management for New Development
15A NCAC 02B .0278—Stormwater Management for Existing Development

15A NCAC 02B .0235—Amended Neuse River Basin Stormwater Requirements
15A NCAC 02B .0315—Amended Neuse River Basin
Falls Lake Background, Rules, and Implementation Schedules
The Falls Lake Project was begun in 1978 by the U.S.Army Corps of Engineers. Construction was
completed in 1981.The lake was created to provide flood control, drinking water supply, protection of
downstream water quality,fish and wildlife conservation, and recreation.
Following questions in 2004 over the condition of Falls Lake, DWQ began more intensive sampling for
use support assessment.A Falls Lake Technical Advisory Committee (TAC) was formed in July 2005 to
assist DWQ with the review and modification of the monitoring strategy and developing levels of
confidence for decision making associated with the monitoring and lake modeling activities.The field
study was completed in fall 2007. Based on water quality data collected between 2002 and 2006, Falls
Lake was listed as impaired for chlorophyll a on the draft NC 2008 303(d) list.The portion of the lake
above 1-85 was also listed as impaired for turbidity.
Page 12 of 16

City of Roxboro Stormwater Annual Report
2022-2023
Following the impairment listing and completion of the study a watershed and lake model were
completed by NC DWQ staff in later 2008 and early 2009 and presented to the TAC for their review. At
the same time a stakeholder process was conducted to educated watershed stakeholders on lake issues,
modeling basics and results, as well as strategy design issues and options. In 2009 and 2010 NC DWQ,
with input from stakeholders, drafted the Falls Lake Rules that would be approved by the Environmental
Management Commission in November 2010.
The Falls Lake Rules are designed to protect and improve water quality in the lake. Specific issues
addressed by the rules include reducing pollution from wastewater discharges, stormwater runoff from
new and existing development, agriculture and fertilizer application.
The primary rules that affect local governments (like the City of Roxboro) are the Stormwater
Management for New Development, Stormwater Management for Existing Development, Protection of
Existing Riparian Buffers, Wastewater Discharge Requirements, and Options for Offsetting Nutrients
Loads.The Protection of Existing Riparian Buffer Rules impacts development within the watershed but is
implemented by NC DENR while the Wastewater Discharge Requirements do not apply to Roxboro
because Roxboro's water supply and wastewater discharge are both in the Roanoke River Watershed.
The New Development Program's went into effect in 2012 and are discussed in the above section of the
report with the NPDES Phase II Post Construction Program.The City of Roxboro adopted the first stage
of its Existing Development Program in January 2012.The first stage for Roxboro was to complete a
"Stage 1 Inventory."
Existing Development Stage 1 Programs
The City of Roxboro's Stage 1 Inventory included information about its Wastewater Collection System,
Discharging Sand Filter Systems and Septic Systems within the City, Potential Restoration Opportunities
in Utility Corridors, Fertilizer Management Plans, Structural Stormwater Practices, and Restoration
Opportunities for Wetlands and Riparian Buffers.
In 2022, a Stage 1 Interim Period Nutrient Reduction Program plan was created and sent in for approval.
This contains plans to reduce any post-baseline interim loading within the City's jurisdictional area to the
baseline loadings.This reduction required within Roxboro will be limited because all development with
the Falls Lake Watershed in Roxboro is also within the Water Supply Watershed and has had at least a
partial offset of nutrient loading.Additionally, development within the last 5 years has been limited
within the Falls Lake Watershed.

Introduction _ ` '•� v r
As part of the City of Roxboro's Stormwater Program,the City has begun preparing an inventory of data - : - •7��
and potential nutrient load reducing activities that the City may use in the future to comply with the `ll :
Falls Lake Existing Development Rule.The City is a brand new NPDES Phase II Permit Holder and the Cityis in the process of creating and implementing many new stormwater programs.

Wastewater Collection Systems
The City of Roxboro operates a Wastewater Collection System that is permitted through NC DENR.The .
Collection System's NPDES Permit Number is WCI,CS00048 and the system is in kept in compliance.The
system was recently inspected by DWQ and no violations were noted. -
Discharging Sand Filter Systems and Septic Systems
The City of Roxboro has no known discharging sand filters and very limited information about septic
systems within the city limits.Septic Systems are regulated through the Person County Health
Department.The City only knows of one area within the city limits that has septic and the City has plans
to provide connections to these 5 homes in the near future.Any information concerning septic should
be in an inventory prepared by Person County.
Restoration Opportunities in Utility Corridors - -
The City of Roxboro is not aware of any restoration opportunities within existing utility corridors. -
Fertilizer Management Plans
All Fertilizer Applicators for the City of Roxboro are appropriately licensed by the North Carolina
Cooperative Extension Service and all application rates would be in accordance with NCCES guidelines.
Structural Stormwater Practices
The City of Roxboro has begun mapping their MS4.The mapping of the MS4 will prioritize the Falls Lake
watershed within the City and will identify structural stormwater practices which will then be inspected
during the mapping process.

Future Existing Development Stage 2 Programs
The City of Roxboro will probably be required to establish a Stage 2 Existing Development Program in
the future.This program will be intended to continue the Stage 1 program and for the City of Roxboro to
provide either of the following:
A. Achieve additional annual reductions in nitrogen and phosphorus loads from existing
development greater than or equal to the average annual additional reductions achieved in the
last seven years of Stage I.
B. Provide for an annual expenditure that equals or exceeds the average annual amount the local
government has spent to achieve nutrient reductions from existing development during the last
seven years of Stage I.
However, it is certainly possible, perhaps even probable that the regulations governing Stage 2 may
change soon.

Stormwater Funding
The City of Roxboro funds it's Stormwater Programs through a Stormwater Fee.The City collects a flat
fee from utility users within the City Limits.The City uses this fee to pay for its Water Quality Programs
including its NPDES Phase II, Falls Lake, and Street Sweeping Programs.The FY 22-23 Adopted
Stormwater Budget was$90,000.00.
In the future,the stormwater budget will need to be increased in order to cover additional expenses for
the Falls Lake Rules.These increases may be offset by converting the current flat fee into an Existing
Residential Unit (ERU) style fee.The ERU is based on an impervious area per property calculation and
will be a more equitable distribution of stormwater costs than the flat fee is. However,the ERU will have
a substantially higher startup and maintenance costs than the current fee has.The future cost of Falls
Lake may be offset by completion of the MS4 Mapping Program.
The Future of Stormwater
Stormwater, and Water Quality in particular, is an evolving field of regulation.The City of Roxboro is
already involved in NPDES Phase II and Nutrient Sensitive Waters. Within the next decade the City needs
to plan for further regulation of these issues as well as several other outstanding issues. EPA continues
to work on two potentially large future items that include a Numerical Nutrient Criteria for all surface
waters and a National Stormwater Rule. The Numerical Nutrient Criteria is an EPA supported push
towards establishing nutrient limits for all surface waters. Currently in North Carolina, generally only
reservoirs have nutrient limits and the limits are based upon response indicators.The National
Stormwater Rule, underway since late 2009 and sometimes called NPDES Phase III, will likely address the
following four water quality standards:
• Designated uses of a water body, such as recreation,water supply, aquatic life, or agriculture.
• Water quality criteria to protect designated uses, such as the metals criteria discussed above as
part of North Carolina's ongoing triennial review.
• Antidegradation policies that maintain and protect existing uses and high quality waters from
pollutant discharges that unnecessarily degrade those waters.
• General policies to address program implementation issues.
The proposed wording of the rule is available at this time, and can be found here
http://water.epa.gov/lawsregs/lawsguidance/wqs index.cfm, although its implementation schedule is
unclear but it is expected that it will include a step forward in the City's NPDES Stormwater Program.
