75-10-738. Closure. (1) After completion of the voluntary cleanup plan, an applicant may petition the department for closure of the facility under 75-10-730 through 75-10-738.

(2) Within 60 days of receipt of a petition for closure, weather permitting, the department shall conduct a review to determine that the releases or threatened releases addressed in the voluntary cleanup plan do not pose a significant threat to public health, welfare, or safety or to the environment as determined in accordance with 75-10-721 and that the applicant has:

(a) implemented all appropriate remedial actions;

(b) if necessary, provided for long-term funding for facility maintenance or monitoring; and

(c) reimbursed the department for all remedial action costs of the voluntary cleanup.

(3) In the event that the petition for closure is not approved by the department, the department shall promptly provide the applicant with a written statement of the reasons for denial. Written notification that the petition is approved by the department must include the following language:

"Based upon the information provided by [insert name(s) of applicant(s)] concerning property located at [insert address], it is the opinion of the Montana Department of Environmental Quality that upon completion of the voluntary cleanup plan, no further action is required to ensure that this facility, when used for [insert purposes identified], is protective of existing and proposed uses and does not pose a significant risk to public health, safety, or welfare or the environment at the facility with regard to releases or threatened releases addressed in the voluntary cleanup plan. The department reserves the right to conduct or require further remedial action at this facility if a new release occurs or if the department receives new or different information than presented in the approved voluntary cleanup plan."

(4) After completion of a portion of a facility addressed in the voluntary cleanup plan, the department shall issue a letter of completion notice to the applicant if the department determines that the applicant has satisfied the requirements of subsection (2).
