Approved Uses for Lexington's
Composted Wastewater Biosolids
Wastewater Compost Process:
Lexington's Compost incorporates materials removed from wastewater following multiple treatment processes. This
material has already undergone steps to significantly reduce the occurrence of pathogens prior to composting. The City
also has a comprehensive pretreatment program in place to prevent objectionable or toxic materials from reaching the
treatment plant and the compost production process.
The material removed from wastewater is known as sludge, or biosolids. It is combined with bark, wood chips, grass
clippings, leaves, and sawdust before composting begins. The ingredients are mixed and aerated for 14 to 30 days. During
this time, the materials are stabilized organically. Naturally occurring bacteria breaks down compostable organic
components in the mixture, which produces temperatures in excess of 1310 Fahrenheit. This heat pasteurizes the compost
and produces a material which is free from harmful pathogens.
Finished compost is available to the public at a reasonable cost, but buyers are required to adhere to the rules for proper
use and nutrient application to prevent damage to surface waters and ground water. Application of the compost must
comply with the conditions and uses identified below.
General Uses:
Accepted uses for wastewater compost are:
• Topsoil substitute for land reclamation
• Nursery production of trees and ornamental plants
• Top soil amendment and re -vegetation of disturbed land
• Landscaping in parks and around buildings
• Supplement to potting mixes
• Mulch for trees, shrubs, planting beds and borders
• Establishment of turf grass
Do not use:
• In vegetable gardens or raised beds where root or leaf crops are grown
• On or bordering playgrounds
• On frozen, snow covered, or flooded land
• Within 25 feet of surface waters and in areas prone to flooding (100 year floodplain)
• During a measurable rainfall and less than a day following heavy rainfall
• On steep slopes where compost is easily displaced and transported by precipitation
Keep out of the reach of children
Storing your Compost:
Keep compost under roof or properly contained and covered if not applying it immediately so that rain will not wash it into
surface waters. Plan all landscaping projects for the appropriate weather conditions so that your compost can be
incorporated into the project promptly and avoid contributing nutrients and solids to storm water, ditches, and streams.
Keep compost at least 100 feet from lakes, ponds, and reservoirs, and 25 feet from streams, creeks, storm water ditches or
wetlands. Keep compost a minimum of 100 feet from wells with the exception of monitoring wells.
To prevent unwanted pests from taking up residence, it is recommended that purchasers apply their compost promptly. Do
not exceed 30 days of storage.

Acid Loving Plants:
Our staff report that this material can be used around plants that love acid conditions (azaleas, camellias, etc) as long as a
limited amount is applied.
Lime:
It is recommended that the soils where compost is applied be limed to maintain a soil pH of at least 6.5 units. For most
local lawns, 30 pounds of agricultural lime per 1,000 square feet should be sufficient. For flower beds and border planting
where compost is applied at levels approaching those used for mulches, application of agricultural lime at rates in excess of
45 pounds per 1,000 square feet may be warranted.
For best results, have your soil tested by the North Carolina Department of Agriculture before applying lime, compost, or
other materials. Soil samples are analyzed by the Agronomic Division of the NC Dept. of Agriculture & Consumer Services.
Instructions, soil sampling boxes, sampling tools, and forms are available from the Davidson County Extension Center at 301
E Center St, Lexington, NC 27292. For additional information about soil testing contact the Cooperative Extension Service at
[phone], or go to: httns://content.ces.ncsu.edu/careful-soil-sampling-the-key-to-reliable-soil-test-information.
ARRIying Compost over Large Areas:
When compost is applied over large areas (such as lawns) it can contribute to water pollution if applied at rates exceeding
agronomic rates. A list of the nutrients available in pounds per ton of compost is provided at the time of purchase for
compost users to determine the amount of compost to be applied to soil and not exceed the appropriate nutrient load for
their soil type(s) and selected vegetative cover. You may access the NC State Cooperative Extension Service website for
proper nutrient application rates for various plants/crops for Lexington area soils at htt s: re alisticvields.ces.ncsu.edul.
For more information concerning area soils, plant nutrient needs, and soil testing, contact the NC Dept. of Agriculture &
Consumer Services located at 301 E Center St, Lexington, NC 27292 by phone at [phone]. Information regarding soil
testing and soil nutrient management is also available online at https://content.ces.ncsu.edu/careful-soil-sampling-the-key-
liable-soil-test-information.
For proper nutrient estimation, be aware that a cubic yard of dry City of Lexington compost can weigh 1,500 pounds.
Exceptional Quality Certification:
Lexington's compost is certified to meet the EPA's criteria for a material of Excellent Quality (EC). This means that it
exceeds the criteria for pathogen reduction, toxic materials and nuisance attraction that qualify the compost for the EC
designation.

Using Lexington's Wastewater Compost
Wastewater Compost:
Lexington's Compost uses material removed from wastewater during treatment. This material has already
undergone a preliminary step to significantly reduce pathogens prior to composting. The City has a comprehensive
pretreatment program in place to keep objectionable or toxic materials from reaching the treatment plant.
The material removed from the wastewater is known as sludge or biosolids. It is mixed with a bulking agent (bark,
wood chips, grass clippings, leaves, sawdust) before composting begins. This mixture is mixed and aerated for 14
to 30 days. During this time, the materials are stabilized organically. Bacteria produce temperatures in excess of
1310 Fahrenheit. This heat pasteurizes the compost and produces a material which is free of harmful pathogens.
Application of our compost should be in accordance with the conditions and uses given below
General Uses:
Accepted uses for wastewater compost are:
• To produce a topsoil substitute for land reclaimation
• Nursery production of trees and ornamental plants
• Revegetation of disturbed land
• Landscaping in parks and around building
• To supplement potting mixes
• As a mulch
• Establishing turf grass
Do not use:
• In gardens where root or leaf crops are grown
• In playgrounds
• On frozen, snow covered or flooded land
• Within 10 feet of surface water
• Keep out of the reach of children
Storing your Compost:
• When storing your compost before using, please contain it so that rain will not wash it into
surface waters.
Acid Loving Plants:
Our staff report that this material can be used around plants that love acid conditions (azaleas, camellias, etc) as
long as a limited amount is applied.

Hydrangeas:
Our customers report that when our compost is used around their plants that plants that previously produced blue
blooms, now produce pink blooms. This indicates that the material has some liming effect.
Lime:
It is recommended that the soils where compost is applied be limed to maintain a soil pH of at least 6.5 units. For
most local lawns, 30 pounds of agricultural lime per 1,000 square feet should be sufficient. For flower beds and
border planting where compost is applied at levels approaching those used for mulches, application of agricultural
lime at rates in excess of 45 pounds per 1,000 square feet may be warranted. For best results have your soil tested
by the North Carolina Department of Agriculture before applying compost or other materials.
Applying Over Large Areas:
When compost is applied over large areas (as lawns) it can contribute to water pollution if it is applied at rates
greatly exceeding agronomic rates. For example do not apply more than one ton of compost per 1,000 square feet
where fescue grass is planted. Otherwise, apply at agronomic or recommended rates per the attached form from
the NCDA. One scoop of our compost can weigh 1,800 pounds.
Exceptional Quality Certification:
Lexington's compost is certified to meet the EPA's criteria for a material of excellent quality. This means that it will
meet the criteria for pathogen reduction, lack of toxic materials and nuisance attraction that qualify the compost
for this designation.

SPILL RESPONSE AND MITIGATION PLAN
Lexington Regional Wastewater Treatment Plant
Although one hundred percent of spills cannot be prevented, a team that is well prepared can minimize the effects.
An operator can avert contamination of surface water by being observant and working diligently according to this
plan. There are two storm drain systems serving the main part of the plant; each of these discharges to daylight onto
vegetated areas well before entering surface waters, providing time for spill containment and clean-up.
At the discovery of a spill, quickly look for the source. Stop or slow the flow, and valve off if possible. If material is
highly flammable or hazardous and cannot be approached without specialized training or equipment, call
911.
Next, work to keep the spill out of the storm drain by placing oil absorbent socks, straw bales, soil, or compost
around the spill while contacting one or more of the responsible individuals listed below. Cone off affected area to
identify spill area to others. If the spill has already entered the storm system, contain it within the storm drainage
network by obstructing the outlet with soil or other dense material at the outlet before it leaves the pipe network.
In the case of a spill of highly flammable material (fuels or solvents) or hazardous substances that may harm
the eyes, skin or lungs, don't take chances, call 911. If the spill reaches the creek, call 911.
I. Notify responsible individuals/contacts below:
a. Tom Johnson- Water Resources Utility Director [phone]
b. Reed Blackburn — Assistant Water Resources Director [phone]
c. Will Hodges - Plant Supervisor [phone]
d. Mike Sutton — Chief Operator [phone]
e. Bill Waycaster — Compost Facility Operator [phone]
f. Eglantina Minerali - Lab Supervisor/Pretreatment Coordinator [phone]
g. Fire Department — 911
h. City dispatcher - [phone]
i. Rebekah Gainey -Risk Safety Manager [phone]
If it is a sludge or wastewater spill, and you can't reach any of the first three individuals immediately, call the City
dispatcher at [phone]. Let one of the individuals listed above or the fire department notify the State or EPA if
they determine that it is necessary. The above contacts are responsible to schedule any environmental remediation
vendors and implement & organize spill clean-up and remediation activities.
For small oil/lubricant spills during maintenance activities, cover entire spill with kitty litter/oil dry until fully
covered and allow absorbent to contact fluids for 4 to 8 hours, or more if needed (in absence of rainfall). Remove
used absorbent material from surface and place in sealed disposable receptacle or contractor's bag. Reapply in the
same manner if oil remains. Dispose of oil contaminated waste materials properly. For larger spills, contain flow
with oil absorbent socks around spill and cover with absorbent (and straw if needed). Remove spent absorbent in the
same manner as for small spills and repeat process until affected area is clean and contaminated absorbent is
discarded appropriately. If oil or lubricants contaminate soil, contact one of the responsible individuals above to
organize the clean-up.
H. Inventory of spill containment supplies located at site to identify, remove and correct affected areas
The City maintains an inventory of materials to intercept, contain and remove spills including, but not limited to:
• Compost, leaves, saw dust/wood chips
• 6 bales of straw
• 100 pounds of kitty litter or oil dry
• 4 oil absorbent socks
• 6 large traffic cones & caution tape
The noted spill containment and clean-up materials are stored at the following buildings identified in the map below.

Sampling and Monitoring Plan
Names and titles of personnel responsible for conducting the sampling and monitoring:
Laboratory analyses— Eglantina Minerali — Laboratory Supervisor
Temperatures— Bill Waycaster—Compost Facility Operator
Compost samples- Bill Waycaster— Laboratory Supervisor
Belt press residuals- Bill Waycaster
The following monitoring & sampling procedures assure that representative samples are being collected with ORC
review and approval.
Temperatures for compost product certification are taken twice daily by the compost operator with a thermometer
certified by the WWTP Laboratory Supervisor. Temperatures are taken within each of the active bays of the compost
production building and each active compost windrow within each of 6 zones per compost row/pile; Zone 1 being the
top 36" of the pile and each successive zone is 30' below the previous.
Compost temperatures are recorded on forms located at the Compost Production Facility. These records are reviewed
daily by the Compost Supervisor to guaranty compliance with permitting and product quality requirements.
Metals. nutrients, non -hazardous determination, pathogen & vector monitoring sampling is completed at the frequency
specified per the City's Compost Production and Distribution Program permit. Compost samples are collected by the
operator from compost production that assures a representative sample of finished compost is collected.
Samples are sent to a NC certified laboratory at least once per year to verify that compost meets NC DEQ test
parameters for RCRA non -hazardous determination limits. Compost samples are submitted to the NC certified
laboratory for metals and nutrients at least 6 times per year to verify that compost meets Exceptional Quality
requirements and NC DEQ permitting limits. Pathogen & vector attraction reduction requirements are verified and
documented by the WWTP lab on average once per week, depending upon compost production schedules.

Moisture is measured and recorded as % for the following materials at the frequency as described:
Residuals -samples are collected by belt press operators and submitted for moisture analysis to the WWTP
laboratory. These results are reviewed by the WWTP Supervisor and the Compost Operator.
Compost- samples are collected by compost operators and submitted for analysis to the WWTP laboratory. The
results are reviewed by the WWTP Supervisor and the Compost Operator.
Active composting for specified compost rows is complete when all vector attraction reduction and pathogen reduction
criteria are met (per 15A NCAC 02T, Section .1100) and compost piles are documented approved for sale on the
Compost Release Form and Lexington Compost -Certification of Exceptional Quality along with limits achieved for
pathogen and vector attraction reduction. Compost percent solids and fecal coliform density are also verified by the
WWTP Laboratory Supervisor as recorded on the Laboratory Worksheet for Compost Analyses for all materials in
advance of sales.
All samples are collected and all monitoring is conducted under the direction of the Wastewater Treatment Plant's
Laboratory Supervisor. The Laboratory Supervisor is charged with the compliance of these samples under the
provisions of certification of the Lexington Regional WWTP's State issued Laboratory Certificate # 47.
All monitoring and testing records are maintained at the WWTP Office for a minimum of 5 years.
Actions to be taken for observed Non -Compliance
If facilities fail to perform satisfactorily, including the creation of nuisance conditions, due to improper operation &
maintenance of the facility, the WWTP Supervisor will 1) immediately discontinue distribution of composted residuals,
2) contact the Winston-Salem Regional Office supervisor, and 3) take immediate corrective actions to remedy the
situation to return to compliance & proper operation.
In the event that any inspection uncovers a discharge to surface waters for releases that does not meet stormwater
quality, any suspected or confirmed damage to groundwater quality, distribution of non -compliant composted
materials, any non-compliance with permitting limits, process system/unit failures resulting in facility's incapability to
complete adequate residuals treatment, inappropriate/excessive land application of distributed compost of abnormal
quality, spills of residuals from vehicles or pipe systems, or other conditions of non-compliance, the inspector shall
report the matter to the Winston-Salem Regional Office at [phone] as soon as possible and within 24 hours of, or
the next working day following, first knowledge of the occurrence. Outside of normal business hours, emergencies
requiring immediate notice will be reported to the Division of Water Resources Emergency Response number (800) 662-
7956, [phone], or [phone].

City of Lexington
Process Narrative
Residuals are produced by the Lexington Regional Wastewater Treatment Plant, NC0055786. Waste
activated sludge is concentrated in a Diffused Air Flotation unit immediately adjacent to the activated
sludge tanks. The concentrated sludge is pumped to the four tanks (previously used as anaerobic digesters)
where the sludge is further dewatered by decanting supernatant to the head of the treatment system. The
further concentrated sludge is then pumped onto the belt press in the compost facility. The material from
the belt press is stored inside the building which houses the belt press. Any backlogged sludge is stored on
a portion of the old sand drying beds immediately adjacent to the facility for later incorporation into the
compost process. Refer to flow diagram below.
All leachate and surface water runoff from the site area is drained to a centrally located collection system
which flows to the head of the Regional WWTP's second stage influent lift station for treatment.
Finished compost is distributed to customers in bulk. Compost sales are typically small quantities made to
area homeowners or landscapers.
The City's compost qualifies as a Class A material meeting EQ criteria. An informational handout is
provided to customers which describes the City's composting process & finished product and identifies
permitted uses of the material. Additional information is also included regarding proper application of the
compost, a web link to obtain agronomic rates for area soils, and the soil testing process via the NC
Department of Agriculture and CS.
