Subject:
Compliance Evaluation Inspection
Permit # WQ0001122
Facility: Curtis Insulation CLRS
Nash County
On December 4, 2023, Jim Westcott from the Raleigh Regional Office visited your closed loop
recycle system to evaluate compliance with the subject permit. The assistance of Mr. Curtis at
the time of the inspection was appreciated.
The facility is permitted for the operation of the operation of a 900 GPM wastewater treatment
and closed loop recycle facility consisting of a 2.15 MG settling lagoon with recycle of
wastewater back into the manufacturing facility; and all associated piping, valves, controls,
and appurtenances with no discharge of waste to surface waters.
The permit, which was issued March 25, 2019, is effective through January 31, 2025. Division
records indicate the required annual fee for the period ending December 31, 2023, due
January 01, 2023, has been paid.
Findings during the inspection were as follows:
1. Treatment system Operation: The wastewater treatment system shall be effectively
maintained and always operated so there is no discharge to surface waters, nor any
contravention of groundwater or surface water standards. At the time of inspection, the
permittee gave a comprehensive tour of the system components. The treatment system
lagoon is currently not in service and has been offline since 2002. The discharge lines
from the lagoon have been removed. The lagoon freeboard was at the required 2'
2. Proper Operation and Maintenance: The system shall be inspected monthly to make
certain of the proper operation of the drip irrigation system and that the soil is assimilating the
disposed treated wastewater with no surface runoff, and that no objectionable odors are being
generated. Any visible signs of a malfunctioning system shall be documented, and steps taken
to correct the problem. At the time of inspection, the perimeter fencing was secured. The
facility has three monitoring wells on site although sampling had been suspended

when the original facility was removed from operation in 2002. The permittee is
required to notify the division in writing prior to future operations to ensure a startup
inspection is conducted. Sampling of monitoring wells MW-1, MW-2 and MW-3 are
required to be sampled within three months prior to resuming the closed -loop recycle
operations and each November annually thereafter should the facility be in service.
Please continue to periodically inspect and evaluate the wastewater drip irrigation system
components are properly maintained and operating as designed. Maintain all associated
operational records onsite for a period of five years as required by the subject permit.
If you have questions or comments about this inspection or the requirements to take corrective
action (if applicable), then please contact Jim Westcott at james.westcot!kncdenr.gov or 919-
