COASTAL FARMS AND RESIDUALS, LLC
BIOSOLIDS OPERATIONS AND MAINTENANCE PLAN
I. Purpose
To put into place a plan that implements the requirements of North Carolina Department
of Environmental Quality — Division of Water Resources (NCDEQ-DWR) Permit #
WQ0034806 for Coastal Farms and Residuals, LLC (Coastal Farms). Requirements are
included for the industrial and municipal biosolid sources (WWTP's) and Coastal Farms
(land application contractor). All biosolid sources are listed within the permit.
II. Operational Functions
The operational functions of this program involve hauling biosolids from the respective
WWTP's to the land application sites currently permitted under Permit # WQ0034806
and land applying the biosolids in accordance with regulatory requirements. Residuals
will be land applied at or below agronomic rates that are determined using the Realistic
Yield Expectations (RYE) as outlined in the permit. Coastal Farms will also account for
any nutrient sources the landowner/lessee has applied. Some sources will be land applied
as a liquid material utilizing either pumper trucks, vacuum trucks, tractor and pull tank,
and/or a traveling reel system. Some sources will be land applied as a cake material
utilizing a tractor and box spreader. In some instances, biosolids may have to be injected
or surface applied with incorporation depending upon the pathogen and vector attraction
reduction methods employed by the respective WWTP. Whichever method is utilized to
land apply the biosolids, Coastal Farms will spread evenly and at consistent rates.
Biosolids will be land applied on fields that are used for hay production, grazing, or
harvested for animal feed. In the case where biosolids are land applied on fields utilized
for grazing, applications rates will be reduced by 25% in accordance with USDA-NRCS
590 Nutrient Management Standards. Grazed fields will be determined by Coastal Farms
Operations Manager on site.
III. Maintenance Schedules
Coastal Farms will follow the maintenance schedule as recommended by the
manufacturer for the equipment utilized to complete the job within the limits of the
permit.
IV. Safety Measures
Coastal Farms takes pride in operating a safety conscious manner. Employees participate
in regular safety training that is designed to help employees recognize safety issues and
take steps to prevent potential accidents from occurring. Coastal Farms employees have
the authority to stop operations if they think any aspect of the operation is going to lead
to the cause of an environmental or personal accident.

V. Spill Response Plan
• Halt the source of the spill: Such as a ruptured line or valve, or damaged transportation
unit.
• Contain spill: Use straw bales to form a barrier. Straw or hay bales can be obtained
from several sources for this purpose. Soil near the site can also be used to form a barrier
for containment.
• Clean up: Use biosolids application equipment to recover as much of the material as
possible. After the application equipment has recovered as much material as possible, it
will be land applied as per the management plan. A temporary sump pit may be dug in
the containment area and spilled material washed into it to enhance recovery.
• Final Clean up: The ultimate goal will be to restore the spill area to its original
condition if possible.
• Notification: As soon as possible after a spill occurs notify:
• Coastal Farms — Wesley Wooten
• WMSS, PLLC — Martin Mabe
• Department of Environmental Quality
Division of Water Resources
Wilmington Regional Office
• Department of Environmental Quality
Division of Water Resources
Washington Regional Office

• Fire Department if assistance is required for wash down
• Management of clean-up efforts: The field superintendent shall take immediate charge
of the clean-up activities. Additional labor will be requested from Coastal Farms as
needed.
VI. Reporting: Within 24 hours of a spill the field superintendent shall present a written report
detailing the cause of the spill and all action taken in response to the spill. Coastal Farms will
notify the Wilmington regional office as soon as possible, but not more than 24 hours after,
or on the next working day following the occurrence
VII. Inspection Plan
Inspections for the land application of biosolids will be conducted at a minimum of a
weekly at the land application site during land application events. Inspections will consist
of inspecting the current field(s) that are being applied on as well as inspecting random

fields that have previously received biosolids applications. Inspections will be performed
by Coastal Farms personnel on a rotational basis to ensure that all employees are familiar
with the inspection processes. At a minimum, these inspections will consist of the
following: Verify that a residuals analysis has been collected prior to land application
activities being performed and that it meets the criteria for land application.
• Verify that pathogen and vector attraction reduction data has been collected for the
source to be land applied and that it meets the criteria for land application.
• Verify the crop that is planted or is to be planted on the respective field(s).
• Confirm that the correct amount of biosolids are being land applied.
• Confirm that manned equipment has a copy of the permit and the operations and
maintenance plan.
• Check that the field has been properly flagged and that buffers are adhered to.
• Check that proper signage is posted.
• Confirm that records are turned in at the end of each business day.
Inspections will also be conducted by the respective employees of the biosolids
generating facilities (at the source generating facility). Coastal Farms is not
responsible for inspections at the source generating facilities. These inspections
should be conducted by the respective ORC of each facility and should fall under
their own Operations and Maintenance Plans.
VIII. Sampling and Monitoring Plan
• Sampling for this project consists of sampling the soils of the fields in the respective
permit in order to document that the fields are suitable for land application.
Biosolids samples are to be collected by the ORC at the respective source generating
facility. This may include nutrient and metal, pathogen, vector attraction reduction,
and TCLP samples. Samples should be provided to Coastal Farms prior to any land
application activities being performed in order to verify that samples meet regulatory
requirements set forth in the permit. Samples should be collected at the frequency
specified in permit # WQ0034806.
Coastal Farms may perform alkaline stabilization of biosolids at some of the
respective source generating facilities. However, it the responsibility of the ORC at
each facility to provide documentation of times, temperatures, and pH of the biosolids
for the lime stabilization events. Each ORC at the respective source generating facility
must be certified by the NCDEQ-Lab Certification Unit before collecting this data.
Coastal Farms only provides the alkaline stabilization materials and personnel to
perform this operation and is not responsible for the documentation that the
biosolids have passed the alkaline stabilization process.
