75-10-736. Approval of voluntary cleanup plan -- time limits -- content of notice -- expiration of approval. (1) The department shall review for completeness, including adequacy and accuracy, in accordance with the requirements of 75-10-734, the environmental assessment component of a voluntary cleanup plan and shall provide a written completeness notice to the applicant within 30 days of receipt. The completeness notice must note all deficiencies identified in the information submitted.

(2) Once the department determines that the environmental assessment component of a voluntary cleanup plan is complete, the applicant may submit the remediation proposal component. The department shall review the remediation proposal for completeness, including adequacy and accuracy, in accordance with the requirements of 75-10-734, and shall provide a written completeness notice to the applicant within 30 days of receipt. The completeness notice must note all deficiencies identified in the information submitted.

(3) Once the department determines that the application for a voluntary cleanup plan is complete pursuant to subsections (1) and (2), the department shall provide formal written notification of approval or disapproval within 60 days unless the applicant and the department agree to an extension of the review to a date certain. The review must be limited to a review of the materials submitted by the applicant, public comments, and documents or information readily available to the department. The department shall communicate with the applicant during the review period to ensure that the applicant has the opportunity to address the public comments.

(4) (a) If the department receives five applications for review of either component of a voluntary cleanup plan in a calendar month, including applications deferred from prior months, the department may notify any additional applicants in that month that their plans must be reviewed in the order received. The 60-day period for department completeness review of deferred applications must begin on the first day of the subsequent month that each plan is eligible for review.

(b) The department shall discontinue accepting either component of voluntary cleanup applications when 15 applications are pending and are being reviewed by the department. The department shall establish a waiting list for applications and shall consider the applications in order of submittal.

(c) If the department has received multiple applications for a voluntary cleanup at the same facility, the department shall notify all of the applicants and offer them the opportunity to submit a joint application.

(5) Consistent with the provisions of 75-10-707, the department may access the facility during review of either component of the application and implementation of the voluntary cleanup plan to confirm information provided by the applicant and verify that the cleanup is being conducted consistent with the approved plan.

(6) (a) The department shall approve a voluntary cleanup plan if the department concludes that the plan meets the requirements specified in 75-10-734 and will attain a degree of cleanup and control of hazardous or deleterious substances that complies with the requirements of 75-10-721.

(b) Except for the period necessary for the operation and maintenance of the approved remediation proposal, the department may not approve a voluntary remediation proposal that would:

(i) take longer than 60 months after department approval to achieve the cleanup levels proposed by the applicant under 75-10-734(3)(a)(i) and approved by the department; or

(ii) take longer than 120 months after department approval to achieve the cleanup levels for ground water proposed by the applicant under 75-10-734(3)(a)(i) and approved by the department, including ground water standards identified as applicable or relevant state or federal environmental requirements, criteria, or limitations pursuant to 75-10-721.

(7) If a voluntary cleanup plan is not approved by the department, the department shall promptly provide the applicant with a written statement of the reasons for denial. The denial may be appealed to the board of environmental review in accordance with the provisions of 75-10-732(4).

(8) The approval of a voluntary cleanup plan by the department applies only to conditions at the facility that are known to the department at the time of department approval. If a voluntary remediation proposal is not initiated within 12 months and, except for the period necessary for the operation and maintenance of the approved remediation proposal, is not completed within 60 months after approval by the department, the department's approval lapses. However, the department may grant an extension of the time limit for completion of the voluntary cleanup plan.

(9) If conditions are discovered during implementation of a voluntary cleanup plan that were not identified in the environmental assessment component pursuant to subsection (1), affect the risk to public health, safety, or welfare or the environment, and change the scope of the approved plan, the applicant shall notify the department within 10 days of discovery. The department may require the applicant to submit an amendment to the approved plan to address the conditions or may determine that a voluntary cleanup plan is no longer appropriate pursuant to 75-10-732(3).

(10) Departmental approval is void if the applicant or the applicant's agents:

(a) fail to materially comply with the voluntary cleanup plan;

(b) submit materially misleading information in the application or during implementation of the voluntary cleanup plan; or

(c) fail to report any newly discovered information to the department during the application process or implementation of the voluntary cleanup plan regarding releases or threatened releases of hazardous or deleterious substances within 10 days of discovery of that information.

(11) Within 60 days after completion of the approved remediation proposal described in the voluntary cleanup plan approved by the department, the applicant shall provide to the department a certification from a qualified environmental professional that the plan has been fully implemented, including all documentation necessary to demonstrate the successful implementation of the plan, such as confirmation sampling, if necessary.

(12) Except as provided in 75-10-738(2)(b), the department may not require financial assurance under this part for voluntary cleanup plans approved under this section.

(13) If a person who would otherwise not be a liable person under 75-10-715(1) elects to undertake an approved voluntary cleanup plan, the person may not become a liable person under 75-10-715(1) by undertaking a voluntary cleanup if the person materially complies with the voluntary cleanup plan approved by the department pursuant to this section.

(14) Immunity from liability under this section does not apply to a release that is caused by conduct that is negligent or grossly negligent or that constitutes intentional misconduct.
