Me. Stat. tit. 38 § 1367
Each responsible party is jointly and severally liable for all costs incurred by the State resulting from hazardous substances at the site or from the acts or omissions of a responsible party with respect to those hazardous substances and each responsible party is jointly and severally liable for all costs incurred by the State for the abatement, cleanup or mitigation of the threats or hazards posed or potentially posed by an uncontrolled site, including, without limitation, all of the State's costs of acquiring property. Each responsible party also is jointly and severally liable for damages for injury to, destruction of loss of or loss of use of natural resources of the State, the reasonable costs of assessing natural resources damages and the costs of preparing and implementing a natural resources restoration plan. The commissioner shall demand reimbursement of costs, including interest, and payment of damages to be recovered under this section. The interest rate charged may not exceed the prime rate of interest plus 4%. Interest must be computed beginning 60 days from the date of a payment demand by the commissioner. Payment must be made promptly by the responsible party or parties upon whom the demand is made. Requests for reimbursement to the Uncontrolled Sites Fund, if not paid within 30 days of demand, may be turned over to the Attorney General for collection or may be submitted to a collection agency or agent or an attorney retained by the department with the approval of the Attorney General pursuant to Title 5, section191. The Attorney General or an attorney retained by the department may file suit in the Superior Court and, in addition to relief provided by other law, may seek punitive damages. Notwithstanding the time limits stated in this paragraph, neither a demand nor other recovery efforts against one responsible party may relieve any other responsible party of liability.
In any suit filed under this section, the State need not prove negligence in any form or matter by a defendant. The State need only prove that a defendant is a responsible party, as defined in section 1362, and the site poses or posed or potentially poses or posed a threat or hazard to the health, safety or welfare of any citizen of the State or the environment of the State, to which the acts or omissions of the defendant are or were causally related.
A person who would otherwise be a responsible party is not subject to cost recovery by the State for the State's abatement, clean-up or mitigation costs or for damages under this section, if the person can establish by a preponderance of the evidence that threats or hazards posed or potentially posed by an uncontrolled site, for which threats or hazards the person would otherwise be responsible, were caused solely by:
For a property acquisition prior to January 1, 1994, the State and the court shall take into account any specialized knowledge or experience on the part of the person, the relationship of the purchase price to the value of the property if uncontaminated, commonly known or reasonably ascertainable information about the property, the obviousness of the presence or likely presence of contamination of the property and the ability to detect that contamination by appropriate inspection.
Funds recovered under this section must be deposited into the Uncontrolled Sites Fund and must be used by the department to carry out the purposes of this chapter.
