Reclamation Facility
High -Rate Infiltration System
Onslow County
In accordance with your permit minor modification request received November 22, 2013, and
subsequent additional information received February 24, 2014, we are forwarding herewith Permit No.
WQ0029945 dated February 28, 2014, to Onslow Water and Sewer Authority for the construction and
operation of the newly permitted facilities, as well as the continued operation of the existing wastewater
treatment and high -rate infiltration facilities.
The modifications to the subject permit are as follows: a new 2.4 MGD headworks system with
two mechanically cleaned fine screens, an auxiliary manually cleaned bar screen, a Eutek HeadCello,
GritCupTM and SpiraSnailTM grit removal/dewatering system; two 211 gallon hydropneumatic tanks; and
a 26 gallon per minute (GPM) non -potable water pump. The remaining proposed modifications noted in
the Engineering Plans are replacements or rehabilitation of previously approved facility components.
This permit shall be effective from the date of issuance until April 30, 2015, shall void Permit No.
WQ0029945 issued .tune 1, 2009, and shall be subject to the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements listed in Attachments A and B for
they may differ from the previous permit issuance. Failure to establish an adequate system for collecting
and maintaining the required operational information shall result in fixture compliance problems.
Please note that the permit type is being changed from a non -conjunctive reclaimed utilization
system to a high -rate infiltration system. This change will be made in name only, and is being done to
correctly identify the system type based on the current 15A NCAC 02T rules. Accordingly, all previously
approved setbacks and limitations will remain unchanged.
For your convenience, customized electronic copies of your facility's NDMR and NDAR-2
reporting forms are available for download at: littp://portal.ncdenr.or web/wg/apsAau/reporting.

Please note the following permit conditions have been removed since the last permit
issuance dated .Tune 1, 2009:
➢ Old Condition 11.3. — This condition has been removed because groundwater monitoring
wells are not specified for this facility.
➢ Old Conditions IL I l ., 1I.12., I1.13., 11.14. and IL 15. -- These conditions have been removed
because the permit type has been changed from a non -conjunctive reclaimed water utilization
system to a high -rate infiltration system.
➢ Old Conditions II.16. and 1111.4. — These conditions have been deleted because the Permittee is
not subject to the requirements in 15A NCAC 02H .0404(g).
Please note the following permit conditions and attachments are new since the last permit
