(A) An environmental audit report or any part of an environmental audit report is privileged and, therefore, immune from discovery and is not admissible as evidence in a civil or administrative penalty action, except as provided in §§ 48-57-40 and 48-57-50. These documents are not entitled to the privilege:

(1) information obtained by observation by a regulatory agency;

(2) information obtained from a source independent of the environmental audit;

(3) documents, communication, data, reports, or other information required to be collected, maintained, otherwise made available, or reported to a regulatory agency or any other persons by statute, regulation, ordinance, permit, order, consent agreement, or as otherwise provided by law;

(4) documents prepared either prior to the beginning of the environmental audit or subsequent to the completion date of the audit report, and in all cases, any documents prepared independent of the audit or audit report;

(5) documents prepared as a result of multiple or continuous self-auditing conducted in an effort to intentionally avoid liability for violations;

(6) information which is knowingly misrepresented or misstated or which is knowingly deleted or withheld from an environmental audit report, whether or not included in a subsequent environmental audit report;

(7) information in instances where the material shows evidence of noncompliance with state, federal, regional, or local environmental laws, permits, consent agreements, regulations, ordinances, or orders and the owner or operator failed to either promptly take corrective action or eliminate any violation of law identified during the environmental audit within a reasonable period of time, but not exceeding three years after discovery of the noncompliance or violation unless a longer period of time is set forth in a schedule of compliance in an order issued by the department, after notice in the State Register and following the department’s determination that acceptable progress is being made.

(B) If an environmental audit report or any part of an environmental audit report is subject to the privilege provided for in subsection (A), no person who conducted or participated in the audit or who significantly reviewed the audit report may be compelled to testify regarding the audit report or a privileged part of the audit report except as provided for in § 48-57-30(E) or in §§ 48-57-40 or 48-57-50.

(C) Nothing contained in this chapter may restrict a party in a proceeding before the South Carolina Workers’ Compensation Commission from obtaining or discovering any evidence necessary or appropriate for the proof of any issue pending in the case, regardless of whether evidence is privileged pursuant to this chapter. Further, nothing contained in this chapter may prevent the admissibility of evidence which is otherwise relevant and admissible in a proceeding before the South Carolina Workers’ Compensation Commission, regardless of whether the evidence is privileged pursuant to this chapter. However, the commission, upon motion made by a party to the proceeding, may issue appropriate protective orders preventing disclosure of information outside of the workers’ compensation proceeding.

(D) The privilege created by this section does not apply to criminal investigations or proceedings. Where an audit report is obtained, reviewed, or used in a criminal proceeding, the privilege created by this section shall continue to apply and is not waived in civil and administrative proceedings, and is not discoverable or admissible in civil or administrative proceedings even if disclosed during a criminal proceeding.

(E) Nothing in this chapter may be construed to circumvent the employee protection provisions provided by federal or state law.
