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.

with the conditions and limitations as specified in General Permit AWG400000, the facility's CAWMP,
and this COC.
Please read this COC and the enclosed Swine Farm Digester Waste Management System General
Permit carefully. Condition I.16 requires regional office notification prior to operations of the new farm
digester system. Influent/Effluent monitoring must begin within six months of submission of the Engineer's
Certification for the farm digester system required by Condition I.15. Please pay careful attention to the
record keeping and monitoring conditions in this permit. Please use the most current record -keeping forms.
Session Law 2023-63 requires that the gases collected by a farm digester system begin to be used as a
renewable energy resource as quickly as feasible, but no later than within six months of the collection of
gases. Until the ,gases are being used as a renewable energy resource the gas shall be flared rather than
vented.
Please notify DWR within ten (10) days of each of the following events:
(1) when the digester cover installation is complete with waste inside the digester, and
(2) when the use of the gases as a renewable energy resource begins.
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.
If your Waste Utilization Plan (WUP) 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 .1304 and NRCS standards a 100-foot separation shall be maintained between water
supply wells and any lagoon, storage pond, or any land application of waste.
Please be advised that any violation of the terms and conditions specified in this COC, General Permit
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.
If any parts, requirements, or limitations contained in this COC are unacceptable, you may apply for an
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.
