• A copy of the approved plans and specifications (signed 8/12/2022).
• Engineer's Certification form (to be returned to DWR upon project completion).
• A copy of Wastewater Discharge General Permit NCG550000

DWR understands that the subject property has been judged "unsuitable" for a ground -absorption sewer
system by the Durham County Health Department. Therefore, your authorized consultant, Agri -Waste
Technologies, Inc. (AWT, Inc.) intends to upgrade/install a wastewater treatment system designed to
discharge to Surface Waters of the State in accordance with plans and specifications signed by the
engineer on 8/12/2022. Compliance under General Permit NCG550000 restricts discharge flow, not to
exceed 1,000 gallons per day. This ATC covers treatment facilities for a three (3)-bedroom single-family
residence estimated to discharge 360 gpd (120 gallons per bedroom).

following the manufacturer's guidelines, conducting and documenting inspections, establishing sources
for OEM spare parts and supplies, taking samples for analyses, making necessary repairs, and
documenting said maintenance for the duration of the permit. Please note that the receiving stream is
currently classified and governed as WS-IV; NSW (Water Supply IV; Nutrient Sensitive Waters).
If DWR determines that your discharge contributes to future degradation or impairment of this
waterbody, an individual NPDES permit may be mandatory. Upon DWR's request, the Permittee must
provide records and demonstrate regular efforts to maintain the approved treatment system. The
Division recommends that the Permittee solicit manufacture -certified training, or a qualified contractor
or service to regularly inspect and maintain this treatment system.
Authorization to Construct (ATC) Permit. This ATC details the conditions of installation and
operation. Before startup, activation requires notice to the Raleigh Regional Office (919-791-4200),
attention Scott Vinson, a minimum of three (3) days in advance of discharge. Such notification shall be

documenting compliance "as built" in accord with this ATC and approved plans and specifications
submitted to DWR and signed on August 12, 2022. No changes may be made without prior approval.
Therefore, in accord with the application and the attached approved plans and specifications, DWR
hereby authorizes the installation of upgrades to the existing surface -water discharge treatment system
described as:
• 1,250 Gallon Septic Tank with Effluent Filter
• AdvanTex AX-20 RT Pod system with re -circulating chamber
• UV Disinfection
• Control Panel with Alarm
• Discharge Point with Riprap
• All Piping and Appurtenances
Compliance with the above shall include a leakage test performed on reused tanks and proposed new
tanks, or leak -certified new by the manufacture not to exceed an exfiltration rate of twenty (20) gallons
per twenty-four (24) hours per 1,000 gallons of tank capacity. The Engineer's Certification shall serve as
proof of compliance with this condition. Mail the completed Engineer's Certification to:
DEQ / DWR/ NPDES Program
1617 Mail Service Center
Raleigh, NC 27699-1617
❖ The Permittee shall, for the life of the treatment facility, maintain on site a copy
of the approved plans and specifications available for DWR inspection.

feet from any water -supply well either on- or off -site. The system shall also be located and constructed

Upon completing construction and prior to operating this permitted facility, a North Carolina -
registered engineer shall sign and submit to DWR the attached Engineer's Certification form, thereby
certifying that the permitted facility has been installed in accordance with the NPDES Permit, this
Certificate of Coverage, this Authorization to Construct, and the approved plans and specifications.
This ATC permit is issued in accordance with Part III, Paragraph 2 of NPDES General Permit
NCG550000, and is subject to revocation unless wastewater treatment facilities are constructed in
accordance with the conditions and limitations specified in this General Permit. In the event that the
facilities fail to perform satisfactorily, including creating nuisance conditions, the Permittee shall take
immediate corrective action as may be required by this Division, such as the construction of additional or
replacement wastewater treatment(s) or disposal facilities. Failure to abide by the requirements of this
ATC permit may subject the Permittee to an enforcement action by the Division of Water Resources in
accordance with North Carolina General Statute 143-215.6A to 143-215.6C.
If any parts, measurement frequencies or sampling requirements contained in this general permit are
unacceptable to you, you have the right to request an individual permit by submitting an individual permit
application. Unless such demand is made, the certificate of coverage shall be final and binding.
This COC is not transferable except after notice to the Division of Water Resources. The Division may
modify or revoke and reissue this COC. This COC does not affect your legal obligation to obtain other
permits that may be required by the Division of Water Resources, the Division of Energy, Mineral and
Land Resources, the Coastal Area Management Act, or any other Federal or Local government.
