which the system was designed.
d. Any process unit failure, due to known or unknown reasons, that render the facility
incapable of adequate residual treatment.
r.,

e. Any spillage or discharge from a vehicle or piping system transporting residuals to the
application site.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.
1. The COMPLL4,NCE BQUNDARY for the disposal system is specified by regulations in

facilities to prevent malfunctions and deterioration, operator errors and discharges which
may cause or lead to the release of wastes to the environment, a threat to human health, or a
nuisance. The Permittee shall maintain an inspection log or summary including at least the
date and time of inspection, observations made, and any maintenance, repairs, or corrective
actions taken by the Permittee. This log of inspections shall be maintained by the Permittee
for a period of five years from the date of the inspection and shall be made available to the
Division of Environmental Management or other permitting authority, upon request.
2. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the application site or facility at any reasonable time for
the purpose of determining compliance with this permit; may inspect or copy any records
that must be kept under the terms and conditions of this permit; and may obtain samples of
