Subject: Permit No. WQ0022916 Correction
Dominguez Wastewater System No. 2
Single Family Residence
Surface Irrigation Facility
Chatham County
In accordance with a request received on rune 29, 2004, we are forwarding herewith the corrected page 2
of Permit No. WQ0022916, issued to Francisco and Debbie Dominguez, for the subject facility.
The following correction has been made to the permit:
1. Condition I.13 of page 2 has been changed from; "Since this house does not comply with
Regulation 15A NCAC 2H .02190)(5)(A)(i) requiring the wetted area to be at least 400 feet from any
habitable residence or place of public assembly under separate ownership, it is required that the
property deed include a provision ensuring that the property cannot be subdivided." to; "The
wastewater facilities permitted under this Permit and the wastewater facilities permitted under Permit
WQ0022914 are located on one tract of land. Since this treatment system does not comply with the
50' buffer between the wetted irrigation field and property lines, it is required that the property deed
include a provision to ensure that this property cannot be subdivided. Both of these permits will have
to be revised by the Division of Water Quality prior to any subdivision of the land taking place. The
Permittee shall be responsible for making the applications necessary for the Permit modification
requests, and for satisfactorily resolving any setback compliance issues that may result from the
proposed subdivision."
Please replace Page 2 with the corrected Page 2 into Pernrit No. WQ002291.6, issued May 13, 2004.
If you have any questions regarding this request, please do not hesitate to contact Michelle McKay at

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 Ieakage 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.
8. The residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
10. The following buffers shall be maintained:
a. 100 feet between wetted area and any residence or places of public assembly under separate
ownership,
b. 50 feet between wetted area and property lines,
c. 100 feet between wetted area and wells,
d. 50 feet between wetted area and drainage ways or surface water bodies,
e. 50 feet between wetted area and public right of ways,
f. 100 feet between treatment/storage units and any wells, and
g. 50 feet between treatment units and property lines.
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. The wastewater facilities permitted under this Permit and the wastewater facilities permitted under
Permit WQ0022914 are located on one tract of land. Since this treatment system does not comply
with the 50' buffer between the wetted irrigation field and property lines, it is required that the
property deed include a provision to ensure that this property cannot be subdivided. Both of these
permits will have to be revised by the Division of Water Quality prior to any subdivision of the land
taking place. The Permittee shall be responsible for making the applications necessary for the Permit
modification requests, and for satisfactorily resolving any setback compliance issues that may result
from the proposed subdivision.
