lined lagoon with a 80 mil HDPE synthetic cover, seven existing clay lined lagoons, five pump stations,
biogas drying units, and all necessary pipes, pumps, land application equipment, and appurtenances, to
serve the pen-nitted swine animal capacity at Farms 27-30 with no discharge of wastes to the surface waters,
in conformity with the project plan, specifications, and other supporting data submitted to and approved by
the Department of Environmental Quality (Department).
This authorization includes the management and land application of animal waste as specified in the
facility's Certified Animal Waste Management Plan (CAWMP) for Farms 27-30, located in Northampton

Wean to Finish: 49,286 Feeder to Finish: Boar/Stud:

If this is a Farrow to Wean or Farrow to Feeder operation, there may be one boar for each 15 sows. Where
boars are unnecessary, they may be replaced by an equivalent number of sows. Any of the sows may be
replaced by gilts at a rate of 4 gilts for every 3 sows.
This COC shall be effective from the date of issuance until September 30, 2024, and shall hereby void
Certificate of Coverage Number AWS660030 previously issued to this facility under General Permit

An adequate system for collecting and maintaining the required monitoring data and operational
information must be established for this facility. Any increase in waste production greater than the certified
design capacity or increase in number of animals beyond that authorized by this COC (as provided above)
will require a modification to the CAWMP and must be approved by the Division of Water Resources
(Division) prior to actual increase in either wastewater flow or number of animals.
Please pay careful attention to the record keeping and monitoring conditions in this permit. Please use the
most current record keeping forms.
If your Waste Utilization Plan (VY'UP) has been developed based on site -specific information, careful
evaluation of future samples is necessary. Should your records show that the current WUP is inaccurate
you will need to have a new WUP developed.
The issuance of this COC does not excuse the Permittee from complying with all applicable laws, rules,
standards, and ordinances (local, state, and federal), nor does issuance of this COC to operate under this
permit convey any property rights in either real or personal property.
Per 15A NCAC 02T .13 04 and NRCS standards a I 00-foot separation shall be maintained between water
supply wells and any lagoon, storage pond, or any land application of waste.

AWG400000 and/or the CAWMP may result in the revocation of this COC, civil penalties per NCGS 143-
215.6A, criminal penalties per NCGS 143-21.613, and/or injunctive relief per 143-215.6C.

individual permit by contacting the Animal Feeding Operations Program for information on the application
process. Unless such a request is made within 30 days, this COC shall be final and binding.
In accordance with Condition 11.23 of General Permit AWG400000, waste application shall cease within
