Operation and Maintenance (O&M) is an important component of a Superfund response to ensure that the remedy performs as intended. Actions range from maintaining engineering containment structures (e.g., landfill covers) to operating ground water remediation systems. Generally, O&M is the responsibility of the Potentially Responsible Parties, States, or other Federal agencies. EPA is responsible for ensuring that the work is adequately performed. EPA also retains funding and operating responsibility for Fund-financed ground water restoration systems for up to 10 years (called Long Term Response Actions) prior to transferring these systems to the States for O&M.
