amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Chatham Development Corporation
Chatham County
FOR THE
construction and operation of a 600 GPD drip irrigation wastewater treatment and disposal system consisting
of a 1500 gallon baffled septic tank, dual recirculating 120 square foot surface sand filters in parallel, a 20
GPM ultraviolet disinfection unit, a 4000 storage/pump tank, a 25 GPM pump, and a 16,104 square feet drip
irrigation area with 2684 emitters to serve Hills of Rosemont Subdivision, Lot No. 18, with no discharge of
wastes to the surface waters, pursuant to the application received January 16, 2001, and in conformity with the
project plan, specifications, and other supporting data subsequently fled and approved by the Department of
Environment and Natural Resources and considered a part of this permit.

following specified conditions and limitations:
I. PERFORMANCE STANDARD
Upon completion of construction and prior to operation of this permitted facility, a ccrtification
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 comp eted in phases and partially certified, you shall
retain the respp—nsibili1y to track further construction a rove un er the samepen-nit, and shall
provide a final certificate of completion once the entire praject has been completed. Mail the
Certification to the Non -Discharge Permitting Unit, 1617 Mail Service Center, Raleigh, NC
27699-1617.
2. The Raleigh Regional Office, telephone number [phone], shall be notified at least forty-

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 drip 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 perforin 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 (Division), 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 recirculating surface sand filters shall be operated and maintained. The
engineer's certification will serve as evidence that these specifications have been met.
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.
A sanitary tee shall be installed on the effluent pipe of the septic tank. The engineer's certification
