How long are maintenance records required to be kept?

Maintenance records are vital for ensuring the proper operation of wastewater facilities, as they provide a historical account of the maintenance activities performed. Keeping these records for a minimum of three years aligns with the regulatory requirements set forth by various environmental agencies. This duration allows for enough time to track performance trends, comply with audits, and provide necessary documentation during inspections.

Preserving maintenance records for three years helps ensure that any potential issues can be reviewed, analyzed, and addressed accordingly. This timeframe supports proper recordkeeping, which is crucial for maintaining compliance with state and federal regulations, thus ensuring water quality and environmental protection.
