A. Notwithstanding any other provision of the Hazardous Waste Act, whenever the secretary is in receipt of evidence that the past or current handling, storage, treatment, transportation or disposal of solid waste or hazardous waste or the condition or maintenance of a storage tank may present an imminent and substantial endangerment to health or the environment, he may bring suit in the appropriate district court to immediately restrain any person, including any past or present generator, past or present transporter or past or present owner or operator of a treatment, storage or disposal facility, who has contributed or is contributing to such activity, to take such other action as may be necessary or both. A transporter shall not be deemed to have contributed or to be contributing to such handling, storage, treatment or disposal taking place after such solid waste or hazardous waste has left the possession or control of such transporter if the transportation of such waste was under a sole contractual arrangement arising from a published tariff and acceptance for carriage by common carrier by rail and such transporter has exercised due care in the past or present handling, storage, treatment, transportation and disposal of such waste. The secretary may also take other action, including but not limited to issuing such orders as may be necessary to protect health and the environment.

B. Any person who willfully violates or fails or refuses to comply with any order of the secretary under Subsection A of this section may in an action brought in the appropriate district court to enforce such order be fined not more than five thousand dollars ($5,000) for each day in which the violation occurs or the failure to comply continues.

C. Upon receipt of information that there is hazardous waste at any site which has presented an imminent and substantial endangerment to human health or the environment, the secretary shall provide immediate notice to the appropriate local government agencies. In addition, the director shall require notice of such endangerment to be promptly posted at the site where the waste is located.
