How long does a certified site assessor have to complete permanent tank closure after notification?

The correct timeframe for a certified site assessor to complete permanent tank closure after notifying the relevant authorities is 60 days. This period is established to ensure that the closure process is conducted efficiently and safely while also allowing sufficient time for proper planning and execution of the closure procedures. The 60-day requirement helps to minimize potential environmental impacts and ensures compliance with regulatory requirements, facilitating the proper handling of any materials associated with the tank and preventing contamination.

In this context, this timeline is significant for ensuring that necessary steps, such as environmental assessments and any required remediation actions, can be performed within a reasonable and regulated timeframe. This promotes accountability and helps maintain the integrity of the environment during the closure of underground storage tanks.
