the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. The drip 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 groundwater resulting from the operation of this facility.
5. The sand media of the surface sand filter must comply with the Division's sand
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
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.
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.

c. The storage system, pump system, and alarm system shall be inspected monthly. The
scum layer shall be removed at the same interval as the septic tank is cleaned out.
