and utilization 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

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 top of reclaimed water pipelines, fastened

accordance with 15A NCAC 02L .0107(b). This disposal system was individually permitted on or
after December 30, 1983; therefore, the compliance boundary is established at either 250 feet from
the effluent disposal area, or 50 feet within the property boundary, whichever is closest to the effluent
disposal area. An exceedance of groundwater standards at or beyond the compliance boundary is
subject to remediation action according to 15A NCAC 02L .0106(d)(2) as well as enforcement
actions in accordance with North Carolina General Statute 143-215.6A through 143-215.6C.
9. In accordance with 15A NCAC 02L .0108, the review boundary is established midway between the
compliance boundary and the high -rate infiltration effluent disposal area. Any exceedance of
groundwater standards at the review boundary shall require action in accordance with 15A NCAC
02L .0106.
10. The compliance and review boundaries for bulk conjunctive reclaimed water utilization activities
have not been established pursuant to 15A NCAC 02T .0910(a)(5). Any exceedance of standards
shall require action in accordance with 15A NCAC 02L .0106.

Onslow County Register of Deeds an easement running with the land containing the following items:
a. A notice of the permit and number or other description as allowed in 15A NCAC 02L .0107(f)(1);
b. Prohibits construction and operation of water supply wells within the compliance boundary; and
c. Reserves the right of the Permittee or the State to enter the property within the compliance
boundary for purposes related to the permit.
The Director may terminate the easement when its purpose has been fulfilled or is no longer needed.
14. The facilities permitted herein shall be constructed according to the following setbacks:

number [phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. if TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents
Comprising this TOC concentration. lr the TOC concentration as measured in the background monitor well exceeds 10 mg/1, this concentration will be taken to represent the naturally occurring
TOC concentration. Any exceedances of this naturally occurring'rOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure I and this attachment

Classification of Biological Water Pollution Control Treatment Systems:
Grade I Biological WPCS
- Septic tank/sand filter systems
—Biological lagoon systems
- Constructed wetlands and associated appurtenances
Grade II Biological WPCS
- Systems that utilize an activated sludge or fixed growth process with a permitted flow
less than or equal to 0.5 million gallons per day (mad)
Grade III Biological WPCS
- Systems that utilize an activated sludge or fixed growth process with a permitted flow
of greater than 0.5 through 2.5 million gallons per day (mad)
- Grade II systems that are required to achieve biological nutrient reduction
Grade IV Biological WPCS
- Systems that utilizing an activated sludge or fixed growth process with a permitted flow
of greater than 2.5 million gallons per day (mad)
- Grade III systems that are required to achieve biological nutrient reduction
* Biological Nutrient Reduction -
The reduction of total nitrogen or total phosphorous by an activated sludge or fixed growth
process as required by the facilities permit.
Classification of Collection Water Pollution Control Systems -
(whichever provides lowest grade)
✓Same grade as biological water pollution control system. Grade of system:
Based on population served:
1,500 or Less = Grade I
1,501 to 15,000 = Grade II
15,001 to 50,000 = Grade III
50,001 or more = Grade IV
