amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Chatham Development Corporation
Chatham County
construction and operation of a 480 GPD spray irrigation wastewater treatment and disposal system
consisting of a 1,000 gallon baffled septic tank, a 1,000 gallon sand filter dosing tank, a 144 ft2 covered,
free -access surface sand filter (dual cells, each 6 feet by 12 feet), a tablet chlorinator, a 3,000 gallon
storage/pump tank, and a 19,800 ft2 spray irrigation area (areas 2 and 3 on the approved plans), with a
minimum wetted area of 12,632 ft2, to serve Lot #6 of Hickory Trace Subdivision, with no discharge of
wastes to the surface waters, pursuant to the application received December 6, 1995, and in conformity
with the project plan, specifications, and other supporting data subsequently filled 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 December 31, 2000, and shall be
subject to the following specified conditions and limitations:
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 [phone], shall be notified at least
Pony -eight (48) hours in advance of operation of the installed facilities so that an in -place

the normal office hours from -8:00 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
Environmental Management, 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 groundwaters resulting from the operation of this facility.
5. The sand media of the covered, free -access surface sand filter 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
Environmental Management.
10. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
11. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under

condition that will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
