Attachment B;
a local reclaimed water permitting program included in the Town's North Cary reclaimed water permit
WQ0017923 (master reclaimed water program permit);
the reclaimed water treatment and distribution facilities associated with the South Cary Water
Reclamation Facility shall consist of the following minimum components: two (2) continuous turbidity
monitoring and recording devices with audible and visual alarms and automatic shut-off controls at the
existing ultraviolet disinfection and effluent structure; pumps with a low water level alarm and automatic
shut-off control; a treatment system consisting of a 1,000 gallon hypochlorite storage tank, metering
pumps, a 8,000 gallon hydropneumatic tank with a water level control system and air compressor; a
magnetic flow meter; a pressure gauge; a chlorine residual analyzer; and all associated piping, valves, and
appurtenances required to make a complete and operational reclaimed water treatment and distribution
facility;

I. SCHEDULES
1. No later than six months prior to the expiration of this permit, the Permittee shall request renewal of
this permit on approved Division of Water Resources forms. Upon receipt of the request, the Division
of Water Resources will review the adequacy of the facilities described therein, and if warranted, will
renew the permit for such period of time and under such conditions and limitations as it may deem
appropriate. Rule 15A NCAC 02T .0105(d) requires an updated site map to be submitted with the
permit renewal application.
II. PERFORMANCE STANDARDS
1. The reclaimed water generation and distribution facilities small be effectively maintained and
operated at all times so there is no unpermitted 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 utilization areas to adequately assimilate the reclaimed water, the Permittee shall take immediate
corrective actions including Division of Water Resources required actions, such as the construction of
additional or replacement reclaimed water utilization facilities, cessation of reclaimed water
utilization activities, or reclaimed water distribution 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.
3. Reclaimed water produced shall not exceed those limits specified in Attachment A.
4. Reclaimed water distributed through bulk fill stations may only be utilized for the purposes listed in
Attachment B. Any additional uses generally approved by the Division of Water Resources
subsequent to permit issuance and prior to permit renewal shall be considered as being listed in
Attachment B, and the list shall be updated upon permit renewal.
5. The conjunctive use of reclaimed water permitted herein in no way negates, precludes, or invalidates
the Permittee's NPDES permit (Permit No. NC0065102)
6. The following shall be requirements for the reclaimed water distribution, storage, and utilization
facilities:
a. All reclaimed water valves, storage facilities and outlets shall be tagged or labeled to warn the
public and employees that reclaimed water is not intended for drinking.

522) and embossed or integrally stamped or marked "CAUTION: RECLAIMED WATER —
DO NOT DRINK" or be installed with a purple (i.e., Pantone 522) identification tape or
polyethylene vinyl wrap. The warning shall be stamped on opposite sides of the pipe and
repeated every three feet or less.
