41 C.F.R. § 102-75.515
When an eligible public agency submits a plan of use for property for an educational or public health requirement, the disposal agency must transmit two copies of the plan to the regional office of ED or HHS, as appropriate. The ED or HHS must submit to the disposal agency, within 30 calendar days after the date the plan is transmitted, a recommendation for assignment of the property to the Secretary of ED or HHS, as appropriate, or must inform the disposal agency, within the 30-calendar day period, that a recommendation will not be made for assignment of the property to ED or HHS. If, after considering other uses for the property, the disposal agency approves the assignment recommendation from ED or HHS, it must assign the property by letter or other document to the Secretary of ED or HHS, as appropriate. The disposal agency must furnish to the landholding agency a copy of the assignment, unless the landholding agency is also the disposal agency. If the recommendation is disapproved, the disposal agency must likewise notify the appropriate Department.
