PERMISSION IS HEREBY GRANTED TO
Francisco and Debbie Dominguez
Chatham County
FOR THE

system consisting of a 1,250 gallon baffled septic tank with effluent filter; a gravity dosed peat biofilte€ with
submersible collecting bottom; a tablet chlorination (minimum contact time of 30 minutes in the chlorination and
in the pump/storage tank); a 2,000 gallon baffled pump/storage tank (with appropriate floats to provide a
minimum storage of approximately 1,900 gallons), a 14 gallon per minute (gpm) pump, with audible and visual
high water alarms and an automatic rain shutoff device; a 8,200 square foot drip irrigation area divided into four
zones with 1,012 linear feet of tubing per zone with 0.53 gallon per hour (GPH) pressure compensated emitters,

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 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 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 , shall be notified at least forty-eight (48) hours in

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.

3. 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 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 ground waters resulting from the operation of this facility.
5. A leakage test shall be performed on the septic tank and storage/pump tank(s) 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.
6. If excavation into bedrock is required for the installation of the septic tank or peat filter, the pit shall
be lined with a 10 -mil synthetic liner.
7. 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.

11. The pump tank(s) shall have functional audible and visual high water alarms that are external to any
structure.
12. The disposal system shall be connected to a rain or moisture sensor that shall indicate when
wastewater application is not appropriate in accordance with Condition 11(4).
13. Since this house does not comply with Regulation 15A NCAC 2H .02190)(5)(A)(i) requiring the
