NDWRF Reclaimed Water Bulk Distribution Permit Modification
To Whom It May Concern,
The City of Durham is submitting a Permit Application for a minor modification to Permit
Number WQ0032515 for the North Durham WRF Reclaimed Water Bulk Distribution System. The City
of Durham is requesting the modification to allow off -site distribution for the use of Toilet Flushing at the
Mist Lake Facilities. The distribution line from North Durham WRF to Mist Lake has been permitted
with Permit Number WQ0040865.
Modifications requested to the subject permit are as follows:
Off -site distribution of Reclaimed Water to Mist Lake for toilet flushing added to
Attachment D — Approved Bulk Fill Reclaimed Water Uses. Total estimated Reclaimed
Water distribution of 5,400 GPD for toilet flushing.
As the City of Durham has a current permit for the Reclaimed Water Distribution System and is
only requesting to allow distribution for toilet flushing off -site, Contract Drawings and Site Plans have
not been provided. As the equipment has previously been permitted in WQ0032515, the equipment was
not added in RWPI 06-16 and RWBD 06-16 to prevent incorrect equipment identification, and equipment
being permitted multiple times. Please refer to current Permit Number W0032515 for the previous items.
If additional documents or information is required, please contact Patricia Drummey Stiegel at the
information below. Please see the list of additional documents for this permit modification as follows:

RECLAIMED WATER BULK DISTRIBUTION SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules and Regulations
PERMISSION IS HEREBY GRANTED TO
City of Durham
Durham County
FOR THE
continued operation of a reclaimed water bulk fill station consisting of:
two variable frequency drive (VFD) pumps to maintain pressure to the distribution system; a 4-inch
overhead loading arm; a 3-inch quick connect fitting at ground level for distribution to customers; a
hypochlorite chlorination system consisting of a sodium hypochlorite bulk tank with meter pump to supply
chlorine to the pump feed system; a manual valve at the loading station with a turbidimeter, flow meter and
residual chlorine monitor; a catch basin that drains to the headworks; and all associated piping, valves,
controls, and appurtenances;
to serve the North Durham WRF, with no discharge of wastes to surface waters, pursuant to the application
received April 29, 2016, and in conformity with the project plans, specifications, and other supporting data
subsequently filed and approved by the Department of Environmental Quality and considered a part of this
permit.
This permit shall be effective from the date of issuance until November 30, 2021, shall void Permit No.
WQ0032515 issued March 7, 2008, and shall be subject to the following specified conditions and
limitations:
I. SCHEDULES
No later than six months prior to the expiration of this permit, the Permittee shall request renewal of
this permit on official Division forms. Upon receipt of the request, the Division 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. Please note Rule 15A
NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal application.
[15A NCAC 02U .0106, 02U .0109]
WQ0032515 Version 2.0 Shell Version 151201 Page I of 8

II. PERFORMANCE STANDARDS
The subject reclaimed water facilities shall be effectively maintained and operated at all times so there
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 utilization areas to adequately assimilate the
reclaimed water, the Permittee shall take immediate corrective actions including Division required
actions, such as the construction of additional or replacement reclaimed water distribution facilities, or
cessation of reclaimed water utilization activities. [G.S. 143-215.1, 143-213.3(a)]
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. [ 15A NCAC 02B .0200, 02L .0100]
3. Effluent limitations for generated reclaimed water shall not exceed those specified in Attachment A.
[15A NCAC 02U .0300]
4. Reclaimed water distributed through bulk fill stations may only be utilized for the purposes listed in
Attachment D. [G.S. 143-215.1]
5. The conjunctive use of reclaimed water permitted herein in no way negates, precludes, or invalidates
the most recent reissuance of the Permittee's NPDES permit (Permit No. NC0023841), and the
Permittee shall continue to comply with all conditions provided for therein. [G.S. 143-215.1]
6. The following shall be requirements for the reclaimed water distribution facilities:
a. All reclaimed water valves, storage facilities and outlets shall be tagged or labeled to warn the
public or employees that reclaimed water is not intended for drinking. Where appropriate, such
warning shall inform the public or employees to avoid contact with reclaimed water.
b. All reclaimed water piping, valves, outlets and other appurtenances shall be color -coded, taped or
otherwise marked to identify the source of the water as being reclaimed water.
i. All reclaimed water piping and appurtenances shall be either colored purple (i.e., Pantone 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.
ii. Identification tape shall be at least three inches wide and have white or black lettering on purple
(i.e., Pantone 522) field stating "CAUTION: RECLAIMED WATER — DO NOT DRINK."
Identification tape shall be installed on reclaimed water pipelines in a visible manner, fastened
at least every 10 feet to each pipe length and run continuously the entire length of the pipe.
iii. Existing underground distribution systems retrofitted for the purpose of distributing reclaimed
water shall be taped or otherwise identified as noted above. This identification need not extend
the entire length of the distribution system, but shall be incorporated within 10 feet of crossing
any potable water supply line or sanitary sewer line.
c. All reclaimed water valves and outlets shall be of a type, or secured in a manner, that permits
operation by authorized personnel only.
d. Hose bibs shall be located in locked, below grade vaults that shall be labeled as being of non -
potable quality. As an alternative to the use of locked vaults with standard hose bib services, other
locking mechanisms such as hose bibs which can only be operated by a tool may be placed above
ground and labeled as non -potable water.
[I5ANCAC 02U .0403]
7. No direct cross -connections shall be allowed betvveen reclaimed water and potable water systems,
unless such connection has been approved by the Department pursuant to 15A NCAC 18C .0406. [15A
NCAC 02U .0403(f)]
