The key information that maintenance records must include according to EO VR 101-E is the name and designated UST operator. This requirement ensures accountability and responsibility for the maintenance of underground storage tank (UST) systems. By documenting who is in charge of the operation and maintenance, it facilitates proper tracking of maintenance activities and establishes a clear point of contact for inspection or regulatory purposes.

Having the designated UST operator's name on record helps regulatory agencies confirm that the UST is being managed according to safety and compliance standards. This documentation is crucial for maintaining the integrity and safety of the UST systems, as it establishes a chain of responsibility and allows for transparent communication between operators and regulatory authorities.

While the date of maintenance, type of maintenance performed, and cost of repairs are also important records to maintain for operational efficiency and historical tracking, they are not specified as the key information required under EO VR 101-E in the same way that the designation of the UST operator is.
