Dear Mr. Davenport:
In accordance with your permit renewal request received June 30, 2021, we are forwarding
herewith Permit No. WQ0015068 dated August 26, 2021, to Robeson County for the continued operation
of the subject wastewater treatment and disposal facilities. Please note that this renewed permit shall

the required operational information shall result in future compliance problems.
The Division has removed the following permit condition since the last permit issuance dated
October 7, 2015:
Old Condition VI.2. This condition has been removed because the permit is not voidable.
The following permit conditions are new since the last permit issuance dated October 7, 2015:
Condition I.1. shall be installed within
180 days of the permit effective date. Upon installation of the metering device, effluent flow
shall be recorded continuously.
Condition II.10. All setbacks applicable to 15A NCAC 02H .0219(j)(5) have been added.
Condition III.4. Disposal equipment shall be tested and calibrated once per permit cycle.
Condition III.13. Metering equipment shall be tested and calibrated annually.
Condition IV.5. The Permittee shall maintain records tracking the amount of effluent
disposed.
