(1) the responsible person has failed or refused to control or clean up the oil and gas wastes or other substances or materials after notice and opportunity for hearing;

(2) the responsible person is unknown, cannot be found, or has no assets with which to control or clean up the oil and gas wastes or other substances or materials; or

(3) the oil and gas wastes or other substances or materials are causing the pollution of surface or subsurface water.

(c) The commission or its employees or agents, on proper identification, may enter the land of another for the purpose of conducting a site investigation or environmental assessment or controlling or cleaning up oil and gas wastes or other substances or materials under this section.

(d) The conducting of a site investigation or environmental assessment or the control or cleanup of oil and gas wastes or other substances or materials by the commission under this section does not prevent the commission from seeking penalties or other relief provided by law from any person who is required by law, rules adopted by the commission, or a valid order of the commission to control or clean up the oil and gas wastes or other substances or materials.

(e) The commission and its employees are not liable for any damages arising from an act or omission if the act or omission is part of a good-faith effort to carry out this section.
