FOR THE
construction and operation of a 360 GPD spray irrigation wastewater treatment and disposal system
consisting of a 1,000 gallon baffled septic tank, dual 180 ft2 vented subsurface sand filters (total area of
360 ft2), a tablet chlorinator, a 2,400 gallon storage/pump tank, and a 14,505 ft2 spray irrigation area to
serve the Yamazawa Residence, with no discharge of wastes to the surface waters, pursuant to the
application received June 17, 1996, and in conformity with the project plan, specifications, and other
supporting data subsequently filed and approved by the Department of Environment, Health and Natural
Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until July 31, 2001, and shall be subject to
the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. 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. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. The Raleigh Regional Office, telephone number 919-571-4700, shall be notified at least

inspection can be made. Such notification to the regional supervisor shall be made during
the normal office hours from 5:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. The spray irrigation facilities shall be effectively maintained and operated at all times so that
there is no discharge to the 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 Pcrmittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
5. The sand media of the subsurface sand filters must comply with the Division's sand
specifications. The engineer's certification will serve as evidence that these specifications
have been met.
6. A leakage test shall be performed on the septic tank and dosing tank 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.
7. If excavation into bedrock is required for the installation of the septic tank or sand filter, the
pit shall be lined with a 10 mil synthetic liner.
8. A sanitary tee 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.
9. 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 North Carolina Division of
Water Quality.
10. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.

of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202. Once
the facility is classified, the Permittee must submit a letter to the Certification Commission
which designates the operator in responsible charge within thirty days after the wastewater
treatment facilities are 50% complete.
3. A suitable vegetative cover shall be maintained.
4. Irrigation shall not be performed during inclement weather or when the ground is in a
condition that will cause runoff.

5. Adequate measures shall be taken to prevent wastewater runoff from the spray field.

(12) month period at an instantaneous application rate not to exceed 0.6 inches per hour.
7. The facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater resulting from the operation of this facility.
8. No type of wastewater other than that from the Yamazawa Residence shall be sprayed onto
the irrigation area.
9. In the event that the sprinkler heads fail to achieve the design diameter of 36 feet due to
obstructions, the obstructions shall be removed or the sprinkler heads shall be raised and
supported to such height that the design diameter is achieved.
10. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
