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 phasesW and partially certified, you shall retain the responsibility to
track further._ construction approved under the same Permit, and shall provide a final certificate of

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 irnmediate 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.

or ground waters resulting from the operation of this facility.
The sand media of the dual bed pressure dosed 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 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.

from the property line with lot #3. This variance shall be recorded with the Chatham County
Register of Deeds Office.
12. The pump tanks shall have functional high water audible and visual alarms. The name and number of
