What should be included in an OSSF operation and maintenance plan?

An OSSF operation and maintenance plan should include regular inspection, pumping schedules, and emergency procedures because these components are essential for ensuring the system functions properly and remains in compliance with regulations. Regular inspections help identify any issues early, such as clogs or leaks, that could lead to system failure or environmental contamination. Pumping schedules are crucial, as they determine when the septic tank needs to be emptied to prevent overflow and backup of sewage. Additionally, emergency procedures are vital for outlining steps to take in case of system failures or unexpected events, thereby protecting public health and the environment.

The other options either suggest practices that are not commonly required or feasible for most OSSF systems, or they do not address the essential components that contribute to effective ongoing maintenance and safety management of the systems. For instance, monthly cleaning and re-zoning of drain fields may be impractical and is not typically a standard requirement, while continuous monitoring without scheduled maintenance contradicts the preventative approach necessary for the longevity of an OSSF. Annual reviews by environmental engineers, while beneficial, may not be a practical or necessary component of a standard operational plan for all systems.
