NDPES Phase II

1. Storm Sewer System Information
1.1 Population Served
The City of Lexington was first settled in 1775 and named their community in
honor of Lexington, Massachusetts, the site of the first skirmish of the American
Revolutionary War. Lexington was incorporated in 1828 by the North Carolina
General Assembly and became the county seat of Davidson County in 1847.
Lexington has a long heritage in furniture making and "Lexington style" barbecue.
According to the 2010 US Census, Lexington has a population of 18,931.
Lexington is home to several festivals and events. The two largest are a one day
Barbeque Festival and a multi -day Kansas City sanctioned Barbeque Cook -Off
event. Even though these events represent increases in people within the City
these are considered major events, as opposed to seasonal population that do
not pose additional burden on the City's MS4.
1.2 Growth Rate
Based upon the 2000 and 2010 US Census', the City of Lexington has
experienced a 6.02% decrease in population. This equates to a negative annual
growth rate of-0.60%. The growth rate has been negatively impacted by the
furniture plant closings in the early 2000s which resulted in the loss of
approximately 3000 jobs. Prior to this time period Lexington had a positive
annual growth.
1.3 Jurisdictional and MS4 Service Area
The total jurisdictional area of the City of Lexington is approximately 18 square
miles. From the City's GIS drainage layer the current MS4 service area covers
approximately 9.5 square miles. The remaining area uses ditches and natural
means of conveyance.
Stormwater Management Plan — Page 1 of 26
NPDES Phase 11

1.4 MS4 Conveyance System
The City of Lexington owns and maintains storm sewer systems that are part of
the City maintained street system, City parks, and public building properties. The
systems are comprised of piped drainage and open or natural channels.
The City Street Department performs typical urban maintenance activities which
include replacement of pipes as needed, rebuilding and adding drainage
structures as needed, keeping pipes open and flowing, and cleaning debris from
the tops of catch basins. The Street Department has a sweeper truck that runs
regularly scheduled routes cleaning curb lines of small accumulations of debris
and litter. Emergency responders handle wreckage debris and control fluid
losses at vehicle accident sites. The Street Department supports Emergency
Responders with personnel and a sweeper as needed for clean-up.
Along with weekly waste and recycle collection, the City's Waste & Recycling
Department also weekly operates a knuckle boom truck and crew citywide to
pick-up yard waste and bulk debris. During leaf season, Waste & Recycling is
assisted as needed by the Street Department and Public Grounds to pick-up
leaves; the majority of which are composted at our Sewage Treatment Plant.
The NC Department of Transportation maintains drainage systems within its
publically maintained rights -of -way inside the City. The NCDOT County
Maintenance Unit is based inside the City Limits of Lexington.
Drainage systems in private streets and drainage ways that are outside the
publically maintained areas listed above are maintained by the abutting property
owners.
1.5 Land Use Composition Estimates
The estimated percentage of the City of Lexington's jurisdictional area is as
follows:
Residential 56%
Commercial 21 %
Industrial 23%
Open Space
Stormwater Management Plan — Page 2 of 25
NPDES Phase 11

Land use estimates were taken from the GIS mapping of the City's zoning
classifications. * Lexington does not have an open space zoning classification.
Currently, Lexington is developing a database of each parcel's actual use which
will give a more accurate reflection of land use composition than zoning (which is
potential use). This data base is expected to be completed summer 2015. It is
expected that open space data will be generated and the percent of actual
Industrial land use will decrease.
1.6 TMDL Identification
Lexington is in the Yadkin- Pee Dee River Basin.
Swearing Creek and Abbotts Creek pass within or on the edge of Lexington's
jurisdiction and are listed on the "2014 Category 5 Water Quality Assessments-
303(d) List". However, no TMDLs for these streams have been established at
this time.

7. Stormwater Management Program Plan
It is the intent of the City of Lexington to develop, implement, and enforce a
sustainable Stormwater Management Program, suited for our area that will
reduce the discharge of pollutants, protect water quality, and satisfy the
appropriate water quality requirements of the Clean Water Act.
7.1 Public Education and Outreach on Storm Water Impacts
The City of Lexington has for several years contracted with an outside agency to
provide a public education program to distribute educational materials to the
community. In conjunction with our partner the City will continue updating and/or
developing our informational materials.
Also, Lexington issues an annual water quality report that has a segment about
protecting the water supply.
The City of Lexington has several festivals and events throughout the year. The
City will continue building on this opportunity to reach out to the community and
region. In prior years we have had an agency that had a booth to provide
stormwater materials at the annual Barbeque Festival. This one day festival
attracts over 100,000 people to the Uptown Lexington. This agency has also
provided hand-outs at local schools. During this permit period the City will
evaluate how best to build on and expand these outreach programs. We believe
schools, festivals, and events represent the best opportunities and are
Lexington's strength to develop a culture of stormwater awareness.
The City of Lexington has a website, enews, and a cable government channel.
Lexington will use these platforms to raise stormwater awareness, provide
stormwater education, advertise, and promote stormwater outreach activities.
7.1.1 BMP Summary Table
The following table outlines what best management practices the City of
Lexington will use in its education program and the measurable goal.

the public on its benefits. Currently, the City has completed the
2nd year of a 4 year implementation plan

7.1.2 Target Audience
The City of Lexington recognizes that all facets of its population should be a
target audience for education of stormwater impacts. Lexington will target youth
in schools, water and sewer customers, and engage the general public through
various media and festival events.
7.1.3 Target Pollutant Sources
With the loss of manufacturing, Lexington will target residential causes of
stormwater pollution. This strategy is subject to change as the City re -develops.
7.1.4 Outreach Program
Lexington's strategy for educational outreach is to attempt to touch as many as
possible over this permit period. Methods will need to be tried, evaluated,
refined, and/or refocused over the permit period. The City will promote education
and outreach at festival events to reach the general public, continue to promote
recycling through the rollout recycling program that is being phased in throughout
the City, continue to educate the public on household hazardous waste
collection, solid waste collection, scrap tire removal, and disposal of white goods.
The City will also use Channel 13, enews, and our website to provide education,
links, and links to videos.
7.1.5 Evaluation of Effectiveness
The educational program measure will be evaluated on the number of brochures
distributed, number of events/meetings held and the attendance, amount of air-
time minutes, and the amount of information presented on the website. Once
these items are quantified, metrics going forward can be established.

7.2.2 Target Audience
As with education, the City of Lexington desires to reach all its citizens.
7.2.3 Participation Program
The City of Lexington will conduct a public meeting to explain and receive citizen
input of the stormwater plan. The City will encourage volunteer involvement &
participation and to continue building a sustainable program.
Each spring the Lexington Appearance Commission (a City Council appointed
board) sponsors a "Cleaner City Campaign" to clean-up neighborhood streets,
parks, and public properties.
Building on its festival strength, and educating through participation, Lexington
recently sponsored a Recycling contest at a Summer Stroll event in its Uptown.
Youth ages 18 & under were invited to create two original artworks interpreting
the theme Recycle -Picture it. The event demonstrated artistic creativity and the
importance of recycling.
7.2.4 Evaluation of Effectiveness
The participation program measure will be evaluated on the number of
participants and physical measurements such as the amount of litter collected.
Once these items are quantified, metrics going forward can be established.
7.3 Illicit Discharge Detection and Elimination
The City of Lexington is concerned about the environment. Over the years, the
sanitary sewer system has been well maintained and monitored. A pre-treatment
and grease trap program is operated and inspections are conducted periodically.
The citizens and city employees call in problems when they see them. The City
will build on this strength to educate the citizens and its employees to watch for
illicit discharges. As Lexington's stormwater program evolves during this permit
period an effective program to detect and eliminate illicit discharges will be
developed.

7.3.2 Storm Sewer System Map
The City of Lexington is fortunate to have a GIS system. It has a drainage layer
that shows storm piping location and size, basins, and direction of flow. This
information was gathered by a City Surveyor in the past and digitized from mylar
maps. Other useful layers to name just a few include creeks and ponds, FEMA
flood information, USGS, lot ownership lines, and property information, aerials
and topos. The City's GIS is powered by information layers supplied from a
variety of Local, State, and Federal sources. The City GIS receives updates
nightly from the County and the City updates its layers of information as needed.
7.3.3 Regulatory Mechanism
To effectively prohibit illicit discharges during the permit period the City will
determine a course of action using ordinances.
7.3.4 Enforcement
The City of Lexington has Code Enforcement Officers that can be called upon as
needed, along with staff in the water and sewer utility that inspects grease traps
and pre-treatment facilities. Going forward the City will determine the best
approach to enforce ordinances.
7.3.5 Detection and Elimination
The City of Lexington owns and operates a sanitary sewer system regulated by
NCDENR. The Operator of Responsible Charge (ORC) is responsible for the
maintenance of the collection system. In the event of a sanitary sewer overflow
(SSO) care is given to follow proper reporting procedures and perform remedial
measures to prevent future occurrences. Routine maintenance techniques
include but are not limited to jetting 10% or more of the sewer lines each year
and subcontracting annual root control operations. The outfalls are inspected by
the crews and mowed to maintain accessibility. The City has a mainline sewer
camera and lateral camera that is used to routinely inspect sewer lines and also
check storm sewer lines when needed. Lexington has pre-treatment ordinances
Stormwater Management Plan — Page 21 of 25
NPDES Phase 11

to prevent heavy metals and toxic materials from entering the sewer system. A
grease trap policy and routine inspections reduce the amount of sewer stops.
Code Enforcement Officers are trained to spot illegal dumping. Water and Sewer
crews as well as Plant personnel in the course of their duties watch for unusual
activities/occurrences while maintaining the collection system and monitoring
what comes through the plant. Pre-treatment & grease trap inspections also
watch for illicit discharges.
Citizens call in sewer stops, septic tank issues (which the City reports to the
County Health Department) and drainage issues. The City will raise public
awareness to call in illicit discharges. This can be addressed by the tools
described in section 7.1 Public Education and Outreach.
7.3.6 Non-Stormwater Discharges
The City of Lexington does not identify and non-stormwater discharges or flows
as a significant contributor of pollutants to its storm system.
7.3.7 Occasional Incidental Non-Stormwater Discharges
The City of Lexington does not anticipate any occasional non-stormwater
discharges to its system.
7.3.8 Outreach
The City of Lexington plans to use educational materials and the water quality to
inform the public about the hazards associated with illicit discharges and
improper disposal of waste. Also, Channel 13, and the website product will be
used. The outreach plan to the public concerning illicit discharges will be an
integral part of both the public education and good housekeeping measures.

Water Quality Report
Best Tasting Water in NC in 1991 and 1995; Second Place in 2002
Information on Lexington's Drinking Water Produced in 2010
North Carolina Public Water Supply I.D. #NCO229010
This brochure is a summary of the quality of water provided by the City of Lexington to its customers from January I through
December 31 of 2010. It is a record reflecting the hard work of the employees involved in treatment and distribution of drinking water
and an affirmation of the City's commitment to provide a safe and reliable supply of water to its customers.
Sources of Lexington's drinking water: The Cities of Lexington and Thomasville
share Lake Thom-A-Lex as a water supply. It is classed as a surface water supply. The
take was constructed in the 1950's and has been the regular source of Lexington's
drinking water since then. The lake initially held 2.2 billion gallons of water. Since the
lake was built, silt has claimed less than 10% of its capacity. The City of Lexington has
installed an aeration system in the lower part of the lake to improve water quality.
In emergencies, the City has two emergency back up supplies: City Lake, which
contains about 150 million gallons of water, and several interconnections with Davidson
Water, Inc. Water must be pumped from City Lake to Lexington's Water Plants The
interconnections with Davidson Water, Inc. provide an opportunity for the two water
systems to support each other in emergencies.
Lexington's water is treated by two plants located on the same site off Old Greensboro
Road at Business I-85. The older plant was built in 1922 and has had several expansions
and upgrades over the years. The newer plant was built in
1967. Together, they are pumping an average of 3 million
gallons of water a day with the capability of pumping over
million gallons a day. Up to 3 million gallons of treated
water is stored at the water plants at any time. The quality
treated water from both plants exceeds state and federal
regulations.

holding up to 2 million gallons of treated water. Water meters are read and billed monthly.
Public comment is welcome at the regularly scheduled meetings of the Lexington Utilities
Commission and the Lexington City Council. The Utilities Commission has its regular
meeting on the first Monday of each month. Its meetings are held at Lexington's City Hall
located at 28 West Center Street starting at 7:00 P.M. The City Council has its regularly
scheduled meetings on the second and fourth Mondays of each month. Its meetings are held
at Lexington's City Hall starting at 7:00 P.M.

Water Conservation Tips:
-When you wash your car, park it in the grass, you'll wash the car and water the grass at the same time.
-Repair dripping faucets. If the faucet is dripping at the rate of one drip per second, you will loose 2,700 gallons of water in a year.
-Run the dishwasher and the clothes washer only when you have a full load. These appliances waste large volumes of water when run
partially loaded.
-The toilet uses more water than anything else in the house. Check for toilet leaks by periodically putting food coloring in the tank. If the
color shows up in the bowl without flushing, you have a leak which needs to be repaired. Do not use the toilet as a wastebasket. Put your
trash in the wastebasket.
-Set lawnmower blades I inch higher. Longer grass means less evaporation
-Mulch trees and plants to reduce evaporation
-Use a broom rather than a hose to clean your sidewalk or driveway
Wastewater Annual Reports: Reports of the operation of the City's wastewater treatment facilities are available for inspection by the
public at regular business hours. Call Roger Spach at 249-3970 for an appointment. These reports are also available on the City of
Lexington's website — www.Lexingtonnc.net

Special notice regarding lead in your drinking water:
If present, elevated levels of lead in drinking water can lead to serious health problems, especially for pregnant women and young
children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The City
of Lexington is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing
components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap
for 30 seconds to two minutes before using the water for drinking or cooking. If you are concerned about lead in your water, you may
wish to have your water tested (the City is not certified to do this testing). Information on lead in drinking water, testing methods, and
steps that you can take to minimize exposure is available at the Safe Drinking Water Hotline [phone] or at
http.epa.gov/safewater/lea&'.
Special Info Available: All sources of drinking water are subject to potential contamination by substances that are naturally occurring or
manmade. These substances can be microbes, inorganic or organic chemicals or radioactive substances. All drinking water, including
bottled water may reasonably be expected to contain at least some of these substances. The presence of these substances does not
necessarily mean that the water poses a health risk.
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such
as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other
immune system disorders, some elderly persons and infants - can be particularly at risk from infections. These people should seek advice
about drinking water from their healthcare providers. Environmental Protection Agency and Centers for Disease Control guidelines on
appropriate means to lessen the risk of infection by Cryptosporidium are available from the EPA's Safe Drinking Water Hotline at 800-
4264791.

What's in your water? In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of
certain contaminants in water provided by public water systems. These may be microbial contaminants, pesticides, herbicides,
organic chemicals and radioactive contaminants. Lexington's water met all state and federal standards for these. Below are
levels of these contaminants found in 2010.

Allow cooking grease to congeal and dispose of it in the trash instead of flushing it down the drain. Grease
will solidify in sewer lines to block them and cause them to overflow onto the ground and into streams!
The State of North Carolina published a Source Water Assessment Program Report in 2003 for the watersheds
providing Lexington's water supplies. Possible sources of contamination such as transportation incidents, chemical
spills, leaking underground storage tank sand old landfill sites were mentioned. For information on this, contact
Roger Spach at 336-248-3970 or [e-mail].
Protect your water supply and that of others! Storm drains do not discharge into the wastewater treatment
plant. They discharge into streams.
�. Chemicals, motor oil, trash, grass clippings, etc should not be dumped into storm drains
�y'' or in locations where they may be washed into ditches or streams. Eventually these will
Hr pollute the water supply of someone downstream of you.
' Be sure that your washing machine does not discharge into a creek. Its water must go
into your septic tank or into the sanitary sewer system
Silt from runoff and trash thrown out onto the ground are some of the major
contributors to pollution in High Rock Lake.
High Rock Lake is a recreation lake. Also, water from the lake enters public water
supplies all the way from its dam to where the Pee -Dee River enters the ocean. Please
make sure that what you do does not contribute to its pollution.
We at the City of Lexington work around the clock to provide top quality water to every tap. We ask all our
customers help us protect our water sources. These are the heart of our community, our way of life and our
children's future.

RE: NPDES Phase 11 Stormwater Program
Slate Designation Process
Dear Ms. Sullins:
February 14, 2011

DENR - WATER QUAt.
Welundy 4 §!gWwa tt Bran!;
The intent of this letter is to provide relevant comments concerning .your letter dated
January,14, 2011, notifying the City of Lexington that we are under consideration for
inclusion in the NPDES Phase 11 Stormwater Program.
The background information attached to your letter indicates several programs and
actions that would be required under the Phase 11 designation and lists criterion that
effects the decision to determine our inclusion in the NPDES Phase 11 Stormwater
Program. The City of Lexington would like to offer the following information that we
feel should justify the City's position that we be excluded from the program. Please
consider the following:
Since early 2005, the City of Lexington along with Davidson County has elected
on our own accord to join the Stormwater Smart Program funded by its members
and managed and coordinated by the Piedmont Triad Council of Government
staff. This program provides strong public education and outreach activities
through middle and elementary schools, civic clubs, and the local scouting troops.
Brochures for wide distribution, newsletters for public buildings, and a website
are all part of the efforts to make the public more aware of the effects of
stormwater on the environment.
• The City of Lexington and Davidson County has employed the PTCOG to
develop a "Lower Abbotts Creek Local Watershed Plan." This is funded by a
federal 319 grant, a CWMTF grant, and local in kind match money (including in
kind contributions by the City to provide monitoring) totaling $255,994.
22 WEST CENTER STREET • LEXINGTON, NORTH CAROLINA 27292 • PH. 336-248-3910 • FAX [phone]

Davidson County, with the assistance of the City of Lexington has adopted a
Master Greenway Plan that includes approximately 90 miles of primary routes,
many of which are along perennial streams. More importantly, Davidson County
applied for and received a $240,000 grant from the CWMTF to go towards the
establishment of a segment of greenway along Abbotts Creek. The County and
City are actively pursuing other grants to make this greenway a reality and serve
as a buffer to protect the impaired waters.
• Davidson County has received a Cleanwater Management Trust Fund grant for
$240,000. This is to provide for easement to produce a buffer of 300 feet on an
impaired section of Abbotts Creek. There is an additional $598,000 involved in
this for greenway construction, acquiring additional grants and in kind match
money from Davidson County and the City of Lexington. The easement is being
purchased on property owned by the City of Lexington for $184,000. Lexington
will turn this money back into the project and will partner with the County on the
greenway.
• The City of Lexington has constructed an on site reuse plant at its municipal golf
course which can provide up to 300,000 gallons per day of highly treated
wastewater to irrigate the golf course.
• The City has installed Biological Nutrient Removal facilities at its wastewater
treatment plant to remove both nitrogen and phosphorous from the effluent.
• Each year, the City publishes information on reducing stormwater pollutants on
its City Website and on the local cable channel.
• Each year, the City includes messages on reducing stormwater pollutants in both
its annual wastewater reports and its water quality reports. This information is
mailed to all of its 22,000 utility customers.
+ The City has enacted an extensive flood plain ordinance that has enabled the City
to obtain a class 7 with the FEMA National Flood Insurance Program
The City has installed and maintains a GIS mapping system, including the creeks
and tributaries.
• The City has developed a new land use ordinance with special provisions to keep
impervious areas to a minimum and provide stream buffers
• The City of Lexington employs a "Street Division" that maintains creeks and
storm drains along with debris removal from street grates.
The City of Lexington has a history of being proactive with its efforts to inform and
educate the public, regulate development, and promote water quality. Also, we have
2

increased our diligence after the designation of several of our streams as impaired. We
are confident that State's investigation will find that the City of Lexington does not
contribute to a violation of water quality, does not discharge contaminates into sensitive
waters, does not contribute to the pollution of water, and has implemented programs that
will continue to improve the quality of our waters.
The City of Lexington has been particularity hard hit during this economic slowdown.
Several factory closings have caused very high unemployment, loss of tax base, and
negative population growth. We strongly feel that the added cost associated with the
Phase 11 designation would be a huge blow to our currently weak economy.
Thank you for the opportunity to comment on the potential Phase H designation. If
further explanation of our comments is required, please let us know.
Sincerely,
ohn L. Gray
