What is the required advance notice for conducting UST decommissioning?

The correct choice indicates that a 30-day advance notice is required for conducting UST decommissioning. This requirement is part of the regulations established to ensure that appropriate preparations are made before commencing with the decommissioning process. Giving advance notice allows regulatory agencies, local authorities, and potentially affected parties to be informed about the upcoming work, ensuring compliance with all necessary environmental safety protocols and permitting processes.

Additionally, a 30-day notice facilitates the scheduling of inspections and ensures that any necessary arrangements or contingencies are addressed prior to the decommissioning activities. This notice period is also vital for maintaining communication with stakeholders concerned about the management of underground storage tanks, which can have implications for public health and environmental safety.
