73 Pa. Stat. § 384
When any authority shall have finally paid and discharged all bonds and the interest due thereon, which shall have been secured by a mortgage on its property or a pledge of any of the revenues or receipts of a project, it shall (subject to any agreements concerning the operation or other disposition of such project) convey such project to the municipality creating the authority. When any authority shall have finally paid and discharged all bonds issued and outstanding and the interest due thereon, or shall have otherwise provided for the payment thereof by the irrevocable deposit of an amount sufficient to pay all sums due, and settled all other claims which may be outstanding against it, it may convey all its property to the municipality creating the authority and may then terminate its existence. A certificate requesting the termination of the existence of the authority shall be submitted to the municipality creating the authority. If the certificate is approved by the municipality, then the certificate endorsed with such approval shall be filed with the Secretary of the Commonwealth who shall then note the termination of existence on the record of incorporation and return the certificate with his approval shown thereon to the board. Thereupon the property of the authority shall pass to the municipality, and the authority shall cease to exist.
