RALEIGH
SINGLE FAMILY RESIDENCE SURFACE IRRIGATION 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
Nazario (Chuck) and Mary Cantu
Onslow County
FOR THE
construction and operation of a 360 gallon per day (GPD) surface irrigation wastewater treatment and disposal
system consisting of a 1,200 gallon baffled septic tank with effluent filter, an in -ground Whitewater DF-50
Aerobic Treatment Unit with dual air compressors, dual tablet chlorinators in parallel, a 11,126 gallon
chlorine contact/pump tank, dual 20 GPM field dosing pumps with a high water alarm light and buzzer, a
standby 8.5 KW generator with transfer switch, a 21,840 square foot drip irrigation area consisting of 4 zones
of 5,460 square feet each with 7 drip lines 390 feet long on a 2 foot spacing and all associated piping and
appurtenances, to serve the Chuck and Mary Cantu residence located at 525-A Grants Creek Road,
Jacksonville, North Carolina, 28540, with no discharge of wastes to the surface waters, pursuant to the request
for modification received April 3, 2008, and in conformity with the project plan, specifications, and other
supporting data subsequently filed and approved by the Department of Environment and Natural Resources
and considered a part of this permit.
This permit shall be effective from the date of issuance until February 28, 2013 and shall be subject to the
following specified conditions and limitations:
I. PERFORMANCE STANDARDS
I. Upon completion of construction and prior to operation of this permitted facility, a certification must
be received from a professional engineer certifying that the permitted facility has been installed in
accordance with this permit, the approved plans and specifications, and other supporting materials. If
this project is to be completed in phases and partially certified you shall retain the res onsibili to
track further construction a roved under the same permit, and shall provide a final certificate of
completion once the entire project has been com leted. Mail the Certification to the Groundwater
Protection Unit, 1636 Mail Service Center, Raleigh, NC 27699-1636.
2. The Wilmington Regional Office, telephone number [phone], shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities so that an in -place inspection can be
made. Such notification to the regional supervisor shall be made during the normal office hours from
8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays,

The surface irrigation facilities shall be effectively maintained and operated at all times so that there
is no discharge to surface waters, nor any contamination of ground waters, which will render them
unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including
the creation of nuisance conditions or failure of the irrigation area to adequately assimilate the
wastewater, the Permittee shall take immediate corrective actions including those actions that may be
required by the Division of Water Quality, such as the construction of additional or replacement
wastewater treatment and disposal facilities.
4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
or ground waters resulting from the operation of this facility.
5. A leakage test shall be performed on the septic tank and storage/pump tank(s) to insure that any
exfiltration occurs at a rate, which does not exceed twenty (20) gallons per twenty-four (24) hours per
1,000 gallons of tank capacity. The Engineer's Certification will serve as proof of compliance with
this condition.
6. If excavation into bedrock is required for the installation of the septic tank, Whitewater DF-50 Unit,
pump tank or other components, the excavation shall be lined with a 10-mil synthetic liner.
7. A sanitary tee and filter shall be installed on the effluent pipe of the septic tank. The Engineer's
Certification will serve as evidence that these specifications have been met.
8. The residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
10. The following setbacks shall be maintained:
a. 100 feet between the wetted area and any residence or places of public assembly under separate
ownership,
b. 50 feet between the wetted area and property lines,
c. 100 feet between wetted area and wells,
d. 100 feet between the wetted area and drainage ways or surface water bodies,
e. 50 feet between the wetted area and public right of ways,
£ 100 feet between the wetted area and any swimming pool,
g. 15 feet between the wetted area and any building foundation or basement,
h. 100 feet between the treatment/storage units and any wells, with the exception of monitoring
wells, and
i. 50 feet between the treatment units and property lines.
11. The pump tank(s) shall have functional audible and visual high water alarms that are external to any
structure.
12. The disposal system shall be connected to a rain or moisture sensor that shall indicate when
wastewater application is not appropriate in accordance with Condition 11(4).
13. All tank access risers shall extend at lest six (6) inches above finished grade and shall be provided
with properly secured covers.
2

14. The installation of fill material over the wetted area as specified in the plans shall only occur when
soil moisture conditions are sufficiently low to ensure that compaction of the underlying subsoil and
rutting of the soil surface will not occur. Fill material shall have USDA soil textures classified as
sand, sandy loam or loam. Fill material shall not contain fibrous organics, building rubble or other
debris. The fill material shall be placed over the application area only after proper preparation of the
original ground surface. Heavy vegetative cover or organic litter shall be removed before the fill
material is added or incorporated. The first layer of fill material and the existing soil shall be mixed
to a depth of six inches below the interface. The type of fill material shall be approved by a licensed
soil scientist prior to placement. The fill area shall be shaped to shed surface water and shall be
stabilized with a vegetative cover to prevent erosion. The side slope of the fill shall not exceed a rise
to run ratio of 1:4. After placement, a soil test of the fill material shall be performed to determine the
addition of lime and fertilizer required for the specific type of vegetation to be established as a
vegetative cover.
15. Within 15 days from the date of completion of the addition of fill material, a post -construction soils
report shall be conducted to confirm that the fill addition was done appropriately and that the
hydraulic loading rates specified in Permit Condition 11.6 remain appropriate. The completed, signed,
sealed soils report shall be submitted to the Groundwater Protection Unit of the Aquifer Protection
Section, at 1636 Mail Service Center, Raleigh, North Carolina 27699-1636 prior to the start of
construction of the wastewater disposal system under this permit.
