SECTION 252:616-5-2. Maintenance and Operation Plan (MOP)

  For tanks and surface impoundments that contain Class I and Class II wastewater, there must be a written Maintenance and Operation Plan (MOP). A MOP may be required for other wastewater classifications based on site specific information. The MOP must be followed, updated annually, if necessary, kept on-site and be available to the DEQ. The MOP must contain the following items:

(1)   Maintenance. The MOP must discuss maintenance procedures including methods to protect impoundments and liner integrity, procedures for solids removal as well as other procedures (such as tank repair or control of soil erosion, removal of deep-root vegetation, and prevention of liner desiccation).

(2)   Operation. The MOP must discuss operation procedures used to protect tank or surface impoundment and liner integrity, as well as other procedures (e.g., influent and effluent flow, sludge removal, sludge storage, changes in waste composition, and freeboard control). Describe procedures to notify the DEQ at the time of a spill or bypass.

(3)   Monitoring. The MOP must discuss the scope and frequency of monitoring activities (such as parameters sampled, sampling frequency, sampling methods, and reporting schedule).

(4)   Personnel. Include the name and phone number of all personnel responsible for maintenance, operation and monitoring activities.
