A regular or routine program of preventive maintenance shall be adhered to. The operations and maintenance manual shall contain a system of maintenance requirements to be accomplished. The routine, minimum preventive maintenance system shall be in accordance with the operations and maintenance manual. Such a system should provide for advanced scheduling of preventive maintenance and should be continually assessed in order to reflect increased service requirements as equipment ages or flow rates increase. Adequate records, files and inventories to assist the operator in his task should also be described in the operation and maintenance manual. Information systems provided for maintenance should describe the documentation required to verify biosolids treatment quality necessary for compliance with permits. Where certain components of the treatment process may be damaged by flooding so as to cause excessive delays in restoring the treatment process to a normal operating level, the means of protecting or removal of such components prior to flooding should be described in the operations and maintenance manual.
