(a) When the authority requires a publicly owned utility to relocate within a high-speed rail property any utility facility lawfully maintained in that property that was not used for high-speed rail purposes at the time the utility facility was originally installed, the authority shall pay the cost of the relocation. (b) When the authority requires a privately owned utility to relocate within a high-speed rail property any utility facility used solely to supply water, which facility is lawfully maintained in any high-speed rail property that was not used for high-speed rail purposes at the time that the utility facility was originally installed, the authority shall pay the cost of the relocation. (c) When the authority requires a privately owned utility to relocate within a high-speed rail property any utility facility, other than one used solely to supply water, which facility is lawfully maintained in any high-speed rail property that was not used for high-speed rail purposes at the time the utility facility was originally installed, and it is established by the utility that the utility is not under express contractual obligation to relocate the utility facility at its own expense, the authority shall pay the cost of the relocation. (d) A permit containing a contractual obligation that was accepted by the utility for maintenance or minor improvement of the facility after the property became high-speed rail property shall not constitute a contractual obligation to relocate a utility facility at its own expense within the meaning of this section. (e) Publicly owned sewers and fire hydrants and any street lighting structure, whether publicly or privately owned, in any high-speed rail property shall be relocated, where necessary, at the expense of the authority.
