(a) It shall be unlawful to release any hazardous substance in the District, unless the release is in quantities permitted by federal or District law or by regulations promulgated by the Mayor to implement this chapter. A lawful release of a hazardous substance shall be reported to the Mayor within 24 hours of the release. The notification to the Mayor shall state the location and condition of the property where the hazardous substance was released and the type of hazardous substance that was released. A violation of this subsection shall be punishable by a fine not to exceed $50,000 or imprisonment not to exceed 5 years, or both. Each violation of this subsection shall constitute a separate offense and the penalties prescribed in this subsection shall apply separately to each offense.
(b) A responsible person shall be strictly liable, jointly and severally, for:
(1) The costs, including the interest on the costs, of an abatement action;
(2) The costs of a remedial cleanup and a health or any other risk assessment;
(3) The costs of any other response action; and
(4) Damages for injury to, destruction of, or loss of natural resources, including the reasonable cost of assessing the injury, destruction, or loss resulting from the release of the hazardous substance.

(2) At the time of contamination, was the owner or operator;
(3) By contract, or an agreement, arranged for the release, disposal or treatment of a hazardous substance on a property;
(4) Arranged for, or was responsible for the transportation of a hazardous substance for release, disposal or treatment at a property;
(5) By an act or an omission, caused or contributed to the contamination of a property if at the time of the act or omission, the person knew or had reason to know that the act or omission would cause the contamination of the property; or
(6) Knew or had reason to know that a property is contaminated and transferred ownership of the contaminated property after June 13, 2001, except if it is established by a preponderance of the evidence that the person did not participate in the management of the property, did not directly cause the contamination, and that the person:
(A) Acquired the contaminated property by inheritance or bequest;
(B) Holds ownership in the contaminated property or in property located on the contaminated property primarily to protect a valid and enforceable lien;
(C) Is a holder of a valid mortgage or deed of trust on a contaminated property, or a holder of a security interest in property located on a contaminated property;
(D) Is a fiduciary who has legal title to a contaminated property or to a property located on a contaminated property for purposes of administering an estate or trust of which the contaminated property or a property located on the contaminated property is a part;

The lender must provide advance written notice of its actions to DDOE, or in the event of an emergency in which action is required within 12 hours, provides notice by telephone. The lender, prior to taking the action, is not a responsible party, and the action taken does not violate any provision of this chapter. Except that if the lender shall contribute to or cause further contamination to the property while taking any action pursuant to this subparagraph, the lender shall be liable solely for costs incurred as a result of the contamination which the lender caused or to which the lender contributed.
(7) A person shall not be considered a responsible person by virtue of conducting an environmental assessment on a property.
(d) To establish that a person did not know or did not have reason to know, as provided in subsections (c)(5) and (6) of this section, the person must have undertaken, at the time of acquisition, all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice in an effort to minimize liability. To determine that a person did not know or did not have reason to know, a court shall consider 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 the likely presence of contamination at the property, and the ability to detect such contamination by appropriate inspection.
