this project is to be com leted in phases and partially certified you shall retain the responsibility to
track further construction approved under the same permit, and shall provide a final certificate of
completion once the entire project has been competed. Mail the Certification to the Non -Discharge
Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617.
2. The Raleigh Regional Office, telephone number (919) 571-4700, shall be notified at least forty-eight

8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays.
3. 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 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 (Division), such as the construction of additional or
replacement wastewater treatment'a'nd 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. -

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
