Any civil action necessary to carry out the provisions of this Subtitle shall be brought by the secretary. In such suits, the secretary shall be represented by the attorney general. If the secretary requests that the attorney general bring a civil action to enforce a provision of this Subtitle and the attorney general declines to institute such action or does not respond to the secretary's request for representation within sixty days of such request and agree to institute a civil action, an attorney from the department may, with the concurrence of the attorney general, institute a civil action to carry out the provisions of this Subtitle.
Except as otherwise provided by law:
Except as otherwise expressly provided within this Subsection, an action, suit, or proceeding by the state for the assessment or enforcement of any civil fine or penalty under the Louisiana Environmental Quality Act shall not be entertained unless commenced within five years from the date when the claim first accrued if, within the same period, the offender is found within the United States in order that proper service may be made thereon. For the purposes of this Subsection, a claim for a civil fine or penalty first accrued when the violation is first reported to the Department of Environmental Quality, in accordance with applicable laws and regulations.
