the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. 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
Environmental Management, 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 groundwaters resulting from the operation of this facility.

specifications. The engineer's certification will serve as evidence that these specifications
have been met.
6. A leakage test shall be performed on the septic tank and dosing tank to insure that any
exfiitration 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.
7. 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 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-

I, Rebecca S. Gaul, Owner agree to operate and maintain the wastewater
treatment system as follows:
1. The Permittee is responsible for the operation and maintenance of the
entire treatment and disposal system, including but not limited to the
following items:
a. The septic tank shall be checked every six (6) months and pumped
out as required, but no less frequently than once per year.
b. The tablet chlorinator shall be checked every week until the
actual usage rate is established and thence on a monthly basis.
Tablets shall be added so as to provide proper chlorination.
C. The storage and pump system shall be inspected monthly. The scum
layer Shall be removed at the same interval as the septic tank is
cleaned out. The alarm system shall be checked. The pump operation
shall be checked.
d. The spray system shall be inspected monthly to make certain of the
sprayers' proper operation, the vegetative growth allows proper
spray patterns, that the soil is absorbing 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 $10,000.00 per day.
3. Failing to meet permit conditions or by violation of the State's sur-
