Subject: Permit No. WQ0003090
Town of Liberty
Wastewater Irrigation System
Randolph County
In accordance with your permit renewal request received November 6, 2013, and subsequent
additional information received December 23, 2013, we are forwarding herewith Permit No. WQ0003090
dated January 10, 2014, to the Town of Liberty for the continued operation of the subject wastewater
treatment and irrigation facilities. Please note that this renewed permit shall become effective on May 1,
2014 (i.e. the day after the expiration date of the existing permit), which differs from the date of this
letter.
This permit shall be effective from May 1, 2014 until April 30, 2019, shall void Permit No.
W00003090 issued May 4, 2005 and shall be subject to the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements listed in Attachments A, B and C
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 future compliance
problems.
Please note that a sludge survey is required for the 15-acre stabilization and storage lagoon (see
Permit Condition I.1.). Please also note that portions of irrigation Zones 1, 2, 3 & 5 have evidence of
ponding and potential runoff during the wet period of the year. These portions are shown on Figure 2 and
are henceforth excluded from irrigation (see Permit Condition 1II.4.). Changes may have to be made to
the spray heads to achieve this. The areas of these Zones have been decreased accordingly on Attachment
B and on Form NDAR-1.
For your convenience, customized electronic copies of your facility's NDMR and NDAR-1
reporting forms are available for download at: http://portal.ncdenr.or web/wq/a s/la au/reRorting.
Please note that on September 1, 2006 State Administrative Code 15A NCAC Subchapter 02T —
Waste not Discharged to Surface Water was adopted. This permit incorporates the requirement of these
rules. Remember to take the time to review this permit thoroughly, as some of the conditions
contained therein may have been added, changed, or deleted from those in previously issued permits.

is no discharge to surface waters, nor any contravention of groundwater or surface water standards.
In the event the facilities fail to perform satisfactorily, including the creation of nuisance conditions
due to improper operation and maintenance, or failure of the irrigation areas to adequately assimilate
the effluent, the Permittee shall take immediate corrective actions including Division required actions,
such as the construction of additional or replacement wastewater treatment or irrigation facilities.
2. This permit shall not relieve the Permittee of their responsibility for damages to groundwater or
surface water resulting from the operation of this facility.

any sale or transfer of property affecting a compliance boundary.
9. In accordance with 15A NCAC 02L .0107(d), no wells, excluding Division approved monitoring
wells, shall be constructed within the compliance boundary except as provided for in 15A NCAC 02L
.0107(g).
