PURPOSE PeraiffiA Section
The Non -Discharge Permit, WQ0010528, issued by the North Carolina Department of Natural
Resources requires the Town to develop an Operation and Maintenance Plan to address the
following aspects of the Surface Disposal of Biosolids:
a) Operational Functions
b) Maintenance Schedules
c) Safety Measures
d) Inspection Plan
e) Sampling & Monitoring Plan
The Permit requires this Plan be submitted to NCDENR for initial approval and any
modifications prior to implementation of the modifications.
OPERATIONAL FUNCTIONS
Description of Wastewater Treatment Plant and Sludge Processes
The Surface Disposal Permit allows disposal of the biosolids from the Town's wastewater
treatment plant and sludge generated by the Town's water treatment plant to the ten acre lagoon.
Following are process descriptions for both the wastewater treatment plant and the water
treatment plant.
The Town of Ramseur Wastewater Treatment Facility is a 0.480 MOD design capacity facility
treating wastewater from residential and commercial users. The unit treatment processes include
an extended aeration, activated sludge basin, secondary clarification and a polishing pond
followed by chlorination and dechlorination. Excess biological sludge from the treatment process
is lime stabilized and piped by gravity feed to an approved, onsite, ten acre sludge storage
lagoon.
The Town of Ramseur Water Treatment Facility is a 1.0 MOD design conventional water
treatment plant. Raw water is gravity feed from Sandy Creek into the sedimentation basins
where chemicals are introduced for taste and odor control, pH adjustment,
flocculationlcoagulation followed by filtration, pH adjustment, and chlorination. The treated
water is stored in an on -site clearwell storage tank. Water is then transferred on demand to
elevated storage tanks and to the customers on the system. The solids collected in the
sedimentation basin are pumped to a clarifier where the clarified water is discharged to Sandy
Page 1 of 10

Creek. The solids collected in the clarifier from the sedimentation basin and back washing the
filters are pumped to sand drying beds for dewatering and transport to the surface disposal
lagoon at the wastewater treatment plant.

MAINTENANCE
The return sludge pump is used to convey the solids to the sludge holding tank. There are 2 submersible
sludge pumps which require monthly cleaning and inspection. The auger system in the lime silo is
inspected monthly and greased as needed.
SAFETY & CONTROL OF ACCESS TO SITES
The surface disposal lagoon is Iocated on property owned by the Town of Ramseur. Entrance to
the property is controlled by a private entrance gate and fencing around the property boundary.
SPILL CONTROL & RESPONSE MEASURES
The Town of Ramseur uses a sludge hauling company to transport the sludge from the water
treatment plant to the surface disposal lagoon at the wastewater treatment plant. The Town will

ensure that the sludge hauling company has a Spill Prevention Control and Countermeasure
(SPCC) Plan and is located in the sludge hauling vehicle. The Plan will include, at a minimum:
a) Emergency Response Procedures addressing control, containment, and remediation
b) Cleanup Procedures
c) Notification Procedures
d) Emergency Contact Information
A copy of the SPCC is included in Attachment I.

Tons per year to the surface disposal lagoon. The sludge generated by the water treatment plant
is exempt from the EPA503 regulations because it does not contain domestic septage sludge.
Sludge samples will be collected I/Year, on a day when a disposal event occurs. Sampling and

Sludge generated by the Ramseur water treatment is transported from the water treatment plant to
the surface sludge disposal lagoon at the Ramseur Wastewater treatment plant. Sludge generated at
the Ramseur Water Treatment Plant is generated by the filter backwash operation and cleaning of
the sedimentation basin. These solids do not contain any sludges generated by domestic sewage.

Spill Prevention measures are critical to preventing spills which can harm the environment, aquatic
life, and humans. Spill Prevention measures such as vehicle and equipment inspections, reviewing
Standard Operating Procedures, and ensuring personnel are properly trained should be completed
prior to transporting sludge to the wastewater treatment plant.
IN THE UNLIKELY EVENT OF A SPILL, THE FOLLOWING ACTIONS SHALL BE
TAKEN IMMEDIATELY:
1. MANAGEMENT OF SPILL ACTIVITIES:
The top priority when responding to spills is to stop it as soon as possible. Stopping the flow is the quickest
way to prevent spills from entering surface waters, posing threat to human health and environment. The
Contract Sludge Hauler shall take immediate charge and initiate assessment and clean-up activities. The
Contract Sludge Hauler labor and equipment is to be utilized. In the event additional labor and equipment is
required, assistance may be requested from the Town of Ramseur, the NC Department of Transportation, and
other private contractors as necessary.
2. HALT THE SOURCE OF THE SPILL:
Such as a ruptured container or damaged transport unit.

3. CONTAIN THE SPILL:
Form a barrier using spill containment materials located at the Ramseur Water and Wastewater Treatment
Plants. In addition, sufficient quantities of straw shall be used for such purposes. Earthen barriers may be
constructed to augment the spill containment material and/or straw bale containment area of the spill. The
Contract Hauler or the person in charge on the spill site will advise the clean-up personnel where to get the
spill containment materials, straw, time, and other items necessary to complete the clean-up operation, i.e.,
local farmers, farm supply centers, nurseries, etc.
4. CLEAN-UP:
Employ front-end loaders, vacuum equipment, sludge application vehicles, and/or local septic tank service to
remove as much of the spilled material as possible. Straw and/or sand should be scattered in the spill area to
soak up the remaining material. The straw- and sand -soaked material will be collected and removed to a
disposal area approved by representatives of the state regulatory agency.
5. FINAL CLEAN-UP:
Employ rotary brush sweeper if needed, and apply time to the spill area upon the approval of the clean-up
efforts by the state regulatory representative. If the event occurs on private property, the clean-up will be
completed to the satisfaction of the property owner and state regulatory representatives. The ultimate goal
will be to restore the spill area to its original condition if possible.
6. NOTIFICATION:
As soon as possible after the spill occurs, the Contract Hauler will notify the Ramseur Water Treatment Plant
and they will then be responsible for notifying the appropriate agencies.
7. REPORTING:
The Town of Ramseur will notify the NCDENR -Winston Salem Regional Office by telephone (336-771-
463 1 ) as soon as possible, but not more than 24 hours after, or on the next working day following the
occurrence. For after-hours reporting the Division's emergency number shall be called to report all
incidences (800-662-7956 or 800-858-0368 or 919-733-3300). The Town of Ramseur will file a written
report to the Winston Salem Regional Office within 5 days of the occurrence.
8. SPILL ESTIMATION METHODS
Accurate spill estimation is critical for reporting purposes. The following types of estimates can be used:
Eyeball Estimate
To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket
contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break
the standing water into barrels and then multiply by 50 gallons. This method is useful for contained
spills up to approximately 200 gallons.
Measured Volume
The volume of most small spills that have been contained can be estimated using this method. The
shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions
are used to calculate the area of the spills and the depth is used to calculate the volume.
Step 1 Sketch the shape of the contained sewage.
Step 2 Measure or pace off the dimensions.
Step 3 Measure the depth at several Iocations and select an average.
Step 4 Convert the dimensions, including depth, to feet.
Step 5 Calculate the area in square feet using the following formulas:
Rectangle: Area = length (feet) x width (feet)
Circle: Area = radius (feet) x radius (feet) x 3.14

Triangle: Area = base (feet) x height (feet) x 0.5
Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in
cubic feet.
Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons
