Any person discharging or suffering the discharge of oil in the manner prohibited by section 543 shall immediately undertake to remove that discharge to the commissioner's satisfaction. Notwithstanding the above requirement, the commissioner may undertake the removal or cleanup of that discharge and may retain agents and contractors for those purposes who shall operate under the direction of the commissioner. The commissioner may implement remedies to restore or replace water supplies contaminated by a discharge of oil prohibited by section 543, including all discharges from interstate pipelines, using the most cost-effective alternative that is technologically feasible and reliable and that effectively mitigates or minimizes damages to, and provides adequate protection of, the public health, welfare and the environment. The commissioner may investigate and sample sites where an oil discharge has or may have occurred to identify the source and extent of the discharge. During the course of the investigation, the commissioner may require submission of information or documents that relate or may relate to the discharge under investigation from any person who the commissioner has reason to believe may be a responsible party. If the commissioner finds, after investigation, that a discharge of oil has occurred and may create a threat to public health or the environment, the commissioner may issue a clean-up order in accordance with section 568, subsection 3.   [PL 2009, c. 501, §4 (AMD).]

Any unexplained discharge of oil within state jurisdiction or discharge of oil occurring in waters beyond state jurisdiction that for any reason penetrates within state jurisdiction must be removed by or under the direction of the commissioner. Any expenses involved in the removal or cleanup of discharges, including the restoration of water supplies contaminated by discharges from interstate pipelines and other discharges prohibited by section 543, whether by the person reporting the discharge, the commissioner or the commissioner's agents or contractors, must be paid in the first instance from the Maine Ground and Surface Waters Clean-up and Response Fund and any reimbursements due that fund must be collected in accordance with section 551.   [PL 2015, c. 319, §14 (AMD).]
