Unless otherwise directed by the department, responsible parties shall submit to the department an operation and maintenance plan when on-site maintenance activities are necessary to implement, monitor or ensure the effectiveness of a remedial or interim action. The plan shall outline all operation, monitoring, and maintenance activities, from design through case closure under ch. NR 726 or through post-closure under ch. NR 727, as appropriate, including all of the following information:(a) The information specified under s.

The department may require progress reports be submitted at a different frequency than semi-annually. Note: Operation and maintenance progress reports should be submitted for both active and passive remediation systems. Progress reports required under this subsection are not the same as post-closure maintenance inspection logs for remedies such as performance standard covers.
Note: Copies of remediation system operation and maintenance reporting forms may be obtained from any regional office of the department, or by writing to the Department of Natural Resources, Bureau for Remediation and Redevelopment, P.O.
