If the department has received eight applications for review of voluntary clean-up plans or no action petitions in a calendar month, the department may notify any additional applicants in that month that their plan or petition will be considered the following month, and the forty-five day period for department review shall begin on the first day of the month following receipt of the plan or petition.
(b) The department shall approve a voluntary clean-up plan if, based on the information submitted by the property owner, the department concludes that the plan will:
(I) Attain a degree of clean-up and control of hazardous substances or petroleum products, or both, that complies with all promulgated applicable state requirements, regulations, criteria, or standards;
(II) For constituents not governed by subparagraph (I) of this paragraph (b), reduce concentrations such that the property does not present an unacceptable risk to human health or the environment based upon the property's current use and any future uses proposed by the property owner.
(c) In the event that a voluntary clean-up plan is not approved by the department, the department shall promptly provide the property owner with a written statement of the reasons for such denial.

(d) The approval of a voluntary clean-up plan by the department applies only to conditions on the property and state standards that exist as of the time of submission of the application.
(2) Written notification by the department that a voluntary clean-up plan is approved shall contain the basis for the determination and the following statement:
Based upon the information provided by [insert name(s) of property owner(s)] concerning property located at [insert address], it is the opinion of the Colorado Department of Public Health and Environment that upon completion of the voluntary clean-up plan no further action is required to assure that this property, when used for the purposes identified in the voluntary clean-up plan, is protective of existing and proposed uses and does not pose an unacceptable risk to human health or the environment at the site.
(3) (a) Failure of a property owner to materially comply with the voluntary clean-up plan approved by the department pursuant to this section shall render the approval void.
(b) Submission of materially misleading information by the applicant in the context of the voluntary clean-up plan shall render the department approval void.
(4) (a) If a voluntary clean-up plan is not initiated within twelve months and completed within twenty-four months after approval by the department, such approval shall lapse; except that the department may grant an extension of the time limit for completion of the voluntary clean-up plan.

(b) A property owner desiring to implement a voluntary clean-up plan after the time limits permitted in paragraph (a) of this subsection (4) shall submit a written petition for reapplication accompanied by written certification of a qualified environmental professional that the conditions on the subject real property are substantially similar to those that existed at the time of the original approval.
(c) Reapplications pursuant to paragraph (b) of this subsection (4) shall be subject to limited review by the department, which shall complete such review within thirty days of receipt of a petition for reapplication; except that any reapplication that involves real property, the condition of which has substantially changed since approval of the original voluntary clean-up plan, shall be treated as a new application and shall be subject to all the requirements of this part 3.
(5) (a) Within forty-five days after the completion of the voluntary clean-up described in the voluntary clean-up plan approved by the department, the property owner shall provide to the department a certification from a qualified environmental professional that the plan has been fully implemented.
(b) If the owner is applying for the tax credit provided in section 39-22-526 (1), C.R.S., or to transfer a transferable expense amount pursuant to section 39-22-526 (2), C.R.S., the owner shall submit to the department the certification along with an application pursuant to section 25-16-303. The certification shall, in addition to certifying that the plan has been fully implemented, disclose the costs of implementation and include supporting documentation of those costs. The department shall then certify the accuracy of the costs and issue the property owner a certificate stating that the clean-up has occurred and the costs of such clean-up.
