Nothing in this Part shall authorize State agencies to impose any duties or obligations in conflict with limitations on State authority established by federal law at the time such agency action is taken. Likewise, no additional liability is established by this Part to the extent that, at the time of the injury, federal law establishes limits on liability which preempt State law. The federal limits on liability established in the Oil Pollution Act of 1990, 33 U.S.C.A. §§ 2701 to 2762, shall not apply to discharges or pollution by oil within the territorial jurisdiction of the State. (1989, c. 656, s. 5; c. 770, s. 75.5; 2010-179, s. 1(d).)
