PERMISSION IS HEREBY GRANTED TO
Arthur Padilla
Chatham County
operation of a 360 GPD spray irrigation wastewater treatment and disposal system consisting of an aerobic
digester tank, air compressor, tablet chlorinator, 1 hp irrigation pump and 9,000 square spray irrigation field to
serve the Padilla Residence, with no discharge of wastes to the surface waters, pursuant to the application
received June 5, 1998, and in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment and Natural Resources and considered a
part of this permit.
This permit shall be effective from the date of issuance until October 7, 2003, shall void Permit No.
WQ0001926 issued August 8, 1989 and October 9, 1989, and shall be subject to the following specified
conditions and limitations -
I. PERFORMANCE STANDARDS
L 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 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.
2. 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.
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.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.

The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and dramageways 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.
Some of the buffers specified above may not have been included in previous permits for this waste
treatment and disposal system. These buffers are not intended to prohibit or prevent
modifications, which are required by the Division, to improve performance of the existing
treatment facility. These buffers do, however, apply to modifications of the treatment and disposal
facilities which are for the purpose of increasing the flow that is tributary to the facility. These
buffers do apply to any expansion or modification of the spray irrigation areas and apply in
instances in which the sale of property would cause any of the buffers 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.
II. OPERATION AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Water Pollution Control System Operators Certification

assigned to the wastewater treatment facilities by the WPCSOCC. The Permittee must also
employ a certified back-up operator of the appropriate type and grade to comply with the
conditions of 15A NCAC 8A .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays,
and must properly manage and document daily operation and maintenance of the facility and must
comply with all other conditions of 15A NCAC 8A .0202. Once the facility is classified, the
Permittee must submit a letter to the WPCSOCC which designates the operator in responsible
charge within thirty days after classification.

obstructions shall be removed or the sprinkler heads shall be raised and supported to such height
that the design diameter is achieved.
