Sec. 20114b. (1) Subject to section 20114(1)(h),  1 a person undertaking response activity under this part may submit to the department a response activity plan that includes a request for department approval of 1 or more aspects of response activity.

(2) A person who submits a response activity plan under this section and who is not subject to an administrative order or agreement or judicial decree that requires prior department approval of response activity shall submit a response activity plan review request form with the response activity plan. The department shall specify the required content of the response activity request form and make the form available on the department's website.

(3) Upon receipt of a response activity plan submitted for approval under this subsection, the department shall approve, approve with conditions, or deny the response activity plan, or shall notify the submitter that the plan does not contain sufficient information for the department to make a decision. The department shall provide its determination within 150 days after the plan was received by the department unless the plan requires public participation under section 20120d(2). 2 If the plan requires public participation under section 20120d(2), the department shall respond within 180 days. If the department's response is that the plan does not include sufficient information, the department shall identify the information that is required for the department to make a decision. If a plan is approved with conditions, the department's approval shall state with specificity the conditions of the approval. If the plan is denied, the department's denial shall, to the extent practical, state with specificity all of the reasons for denial.

(4) If the department fails to provide a written response within the time frames required by subsection (3), the response activity plan is considered approved. If the department denies a response activity plan under subsection (3), a person may subsequently revise and resubmit the response activity plan for approval.

(5) Any time frame required by this section may be extended by mutual agreement of the department and a person submitting a response activity plan. An agreement extending a time frame shall be in writing.

(6) A person requesting approval of a response activity plan may appeal the department's decision in accordance with section 20114e,  3 if applicable.
