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 additional or replacement reclaimed water utilization 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 shall not exceed those specified in Attachment A. [15A NCAC 02U .0300]
4. Reclaimed water may only be utilized at the sites listed in Attachment B. [G.S. 143-215.1]
5. Reclaimed water distributed through bulk fill stations may only be utilized for the purposes listed in

6. 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. NC0025241), and the
Permittee shall continue to comply with all conditions provided for therein. [G.S. 143-215.1]

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."

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.
[15A NCAC 02U .0403]
8. No direct cross -connections shall be allowed between reclaimed water and potable water systems,
unless such connection has been approved by the Department pursuant to 15A NCAC 18C .0406. [15A

testing procedures shall meet water main standards in accordance with 15A NCAC 18C, but in
no case shall reclaimed distribution lines be less than 25 feet from a private well or 50 feet from
a public well.
[I 5A NCAC 02U .0701 ]
