Holidays.

I The surface irrigation facilities shall be effectively maintained and operated at all times so that
there is no discharge to 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 Nater Quality, such as the
construction of additional or replacement wastewater treatment and disposal facilities.

specifications. The Engineer's Certification will serve as evidence that these specifications have
been met.

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.
T 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

with Chatham County Parcel number 71470 (Lot 14A of the Davis Subdivision).
Some of the set -backs specified above may not have been included in previous permits for this
waste treatment and disposal system. These set -backs are not intended to prohibit or prevent

These set -backs do apply to any expansion or modification of the surface irrigation areas and
apply in instances in which the sale of property would cause any of the set -backs now complied
with, for the treatment and disposal facilities, to be violated. The applicant is advised that any
modifications to the existing facilities will require a permit modification.
