What does post-closure care for a TSDF typically include?

• A. Post-closure is a one-time event with no ongoing requirements.
• B. It involves closing the water treatment plant.
• C. Post-closure care includes ongoing monitoring and financial assurance.
• D. It involves expanding the facility's operations.

Answer: (C)

Post-closure care for a TSDF is the long-term obligation that begins after final closure to protect human health and the environment. The key elements are ongoing monitoring and financial assurance. Ongoing monitoring ensures containment remains effective over time—this typically involves groundwater monitoring around the site, maintaining and inspecting the final cover and drainage systems, and ensuring any leachate collection or gas management systems function properly. Financial assurance guarantees that funds are available to cover the costs of continued monitoring, maintenance, potential corrective actions, and cover repairs for the duration of the post-closure period, which lasts for the regulated term (often decades). This isn’t a one-time event, it isn’t about closing a water treatment plant, and it isn’t about expanding operations.
