C Z2 z2 _ County
I agree to operate and maintain the wastewater treatment systetn as follows:
I... The Permittee is responsible for the operation and maintenance of the entire treatment and
disposal system, including, but not limited to, the following items:
The septic tank shall be checked every six months and pumped out as needed. The
effluent filter shall be checked and cleaned at the same frequency as the septic tank.
b. The ultraviolet disinfection unit shall be checked every week. The Iamp shall be cleaned
and/or replaced to ensure proper disinfection.
The storage, pump, and alarm systems shall be inspected monthly. The scum layer shall
be removed at the same time interval as the septic tank is cleaned out.
d. The drip irrigation system shall be inspected monthly to make certain of proper operation,
that the vegetative growth allows proper irrigation patterns, that the soil is assimilating
the disposed treated wastewater with no surface runoff, and that no objectionable odors
are being generated.
2. Failure of the Permittee to properly operate this system is subject to a penalty up to $10,000 per
day.
3. Failure to meet permit conditions or violation of the State's surface or groundwater regulations
will require cessation of occupancy of the building.
I understand that failure to comply with these conditions along with the permit conditions may result in
voiding the permit.

Classification of EaEgutIrrigation Water Pollution Control Systems:
Systems which utilize spray irrigation for the reuse or disposal of wasterwater.
These systems include: septic tanks, sand filter, oil/water separators, lagoons,
storage basins, screening, sedimentation. Systems other than those listed above
shall be subject to additional classification.
Classification of Land Application of Residuals Systems:
Systems permitted and dedicated for land application of residuals that are produced by a
water pollution control system or contaminated soils.
Classification of Physical/Chemical Water Pollution Control Treatment Systems:
Grade I Physical/Chemical: Any water pollution control system that utilizes a primarily
physical process to treat wastewater. This classification includes groundwater
remediation systems. **
Grade II Physical/Chemical: Any water pollution control system that utilizes a primarily
chemical process to treat wastewater. This classification includes reverse osmosis,
electrodialysis, and ultrafiltration systems. **
** Any water pollution control system that utilizes a phyical/chemical process to enhance an
activated sludge or fixed growth process, shall not be subject to additional classification.
Classification of Subsurface Water Pollution Control Systems:
Systems which utilize the soil for subsurface treatment and disposal of wastewater
and/or are required to have a certified operator under 15A NCAC 18A.1961. * * *
*** Any subsurface system that has as part of its treatment process a water pollution control
systems that may be classified under Rules .0302 through .0307 of this section shall be
subject to addional classification.
