INSPECTION SCHEDULES AND PROCEDURES

II.A. Purpose and Scope
Inspections of the M-136 LTTAs and Groundwater Monitoring System are
conducted to promote the detection of malfunctions and deterioration of the
LTTA caps, drainage systems, security equipment and monitoring wells. The
inspection schedules have been designed to detect problems promptly in order to
ensure that the caps, drainage systems and monitoring wells remain in good
condition. The inspection schedules are also used to document problems observed and what corrective action or maintenance was conducted to remedy the problem. Inspections are conducted by personnel trained to identify potential
problem areas and to use the inspection schedule/checklist. The Groundwater
Monitoring System is inspected annually throughout the post-closure period. – the
inspection schedule/checklist is shown below in Table II.B.
II.B. Remedial Action or Maintenance
Repairs or corrective action for any deterioration or malfunction discovered by an
inspection shall be initiated within seventy-two (72) hours except for damaged
security equipment. As stated in Permit Condition II.B.3., repairs to damaged
security equipment shall begin within twenty-four (24) hours. Repairs to security equipment shall be completed as soon as practicable, but not later than seventy-two (72) hours after the problem is discovered. As stated in R315-264-15(c),
where a hazard is imminent or has already occurred, remedial action shall be taken
immediately.

II.C. Inspection Records
All records of inspections and remedial actions shall be retained in the Operating Record, as indicated by condition I.G.16., throughout the post-closure care period.
At a minimum, inspection records shall include the date and time of the
inspection, the name of the inspector, a notation of the observations made, and the
date and nature of any repairs or maintenance taken.
