22 Pa. Code § 142.10 – Title to site.

(a) The municipality or public library shall have or obtain a full title or other interest in the site upon which the public library facility is or will be located, including right of access, that is sufficient to insure the undisturbed use and possession of the facility as a public library for 50 years or the useful life of the project to be funded by the grant, whichever is shorter.
(b) If the title to the site upon which the public library facility is or will be located is held by the municipality, the municipal officials shall pass a resolution or ordiniance ensuring the undisturbed use of the facility as a public library for 50 years or the useful life of the project to be funded by the grant, whichever is shorter.
(c) If during the 50-year period, the municipality or public library desires that the facility be used for other than public library purposes, it may request a waiver from the State Librarian. In deciding whether to grant that waiver, the State Librarian will consider the public library’s need for a facility and how that need will be met.
(d) Recipients of grants for public library facilities under the act may not dispose of nor at any time convert property acquired with the grant to other than the purposes approved in the project application without the prior written approval of the Commissioner of Libraries, the State Librarian. If disposition or conversion occurs without prior written approval, the State Librarian may require:
1. (1) The recipient to refund all grant funds for the particular project, including 10% annual interest compounded four times annually from the date the original grant-in-aid was received until it is repaid.
2. (2) Acquisition by the recipient of equivalent replacement land, as determined by the State Librarian.
