(c) The owner or operator of the CCR unit shall obtain a written certification from a qualified professional engineer that the design of the final cover system meets the requirements of this rule.
(E) Initiation of closure activities. Except as provided in paragraph (E)(4) of this rule and rule 3745-525-730 of the Administrative Code, the owner or operator of a CCR unit shall commence closure of the CCR unit not later than the applicable timeframes specified in either paragraph (E)(1) or (E)(2) of this rule.
(1) The owner or operator shall commence closure of the CCR unit not later than thirty days after the date on which the CCR unit does either of the following:
(a) Receives the known final receipt of waste, either CCR or any non-CCR waste stream.
(b) Removes the known final volume of CCR from the CCR unit for the purpose of beneficial use of CCR.
(2)
(a) Except as provided by paragraph (E)(2)(b) of this rule, the owner or operator shall commence closure of a CCR unit that has not received CCR or any non-CCR waste stream or is no longer removing CCR for the purpose of beneficial use within two years of the last receipt of waste or within two years of the last removal of CCR material for the purpose of beneficial use.
(b) Notwithstanding paragraph (E)(2)(a) of this rule, the owner or operator of the CCR unit may secure an additional two years to initiate closure of the idle unit provided the owner or operator provides written documentation that the CCR unit will continue to accept wastes or will start removing CCR for the purpose of beneficial use. The documentation shall be supported by, at a minimum, the information specified in paragraphs (E)(2)(b)(i) and (E)(2)(b)(ii) of this rule. The owner or operator may obtain two-year extensions provided the owner or operator continues to be able to demonstrate that there is reasonable likelihood that the CCR unit will accept wastes in the foreseeable future or will remove CCR from the unit for the purpose of beneficial use. The owner or operator shall place each completed demonstration, if more than one time extension is sought, in the facility's operating record as required by paragraph (I)(2) of rule 3745-525-50 of the Administrative Code prior to the end of any two-year period.
(i) Information documenting that the CCR unit has remaining storage or disposal capacity or that the CCR unit can have CCR removed for the purpose of beneficial use.
(ii) Information demonstrating that that there is a reasonable likelihood that the CCR unit will resume receiving CCR or non-CCR waste streams in the foreseeable future or that CCR can be removed for the purpose of beneficial use. The narrative shall include a best estimate as to when the CCR unit will resume receiving CCR or non-CCR waste streams. The situations listed in paragraphs (E)(2)(b)(ii)(a) to (E)(2)(b)(ii)(d) of this rule are examples of situations that would support a determination that the CCR unit will resume receiving CCR or non-CCR waste streams in the foreseeable future.
(a) Normal plant operations include periods during which the CCR unit does not receive CCR or non-CCR waste streams, such as the alternating use of two or more CCR units whereby at any point in time one CCR unit is receiving CCR while CCR is being removed from a second CCR unit after its dewatering.
(b) The CCR unit is dedicated to a coal-fired boiler unit that is temporarily idled (e.g., CCR is not being generated) and there is a reasonable likelihood that the coal-fired boiler will resume operations in the future.
(c) The CCR unit is dedicated to an operating coal-fired boiler (i.e., CCR is being generated); however, no CCR are being placed in the CCR unit because the CCR are being entirely diverted to beneficial uses, but there is a reasonable likelihood that the CCR unit will again be used in the foreseeable future.
(d) The CCR unit currently receives only non-CCR waste streams and those non-CCR waste streams are not generated for an extended period of time, but there is a reasonable likelihood that the CCR unit will again receive non-CCR waste streams in the future.
(c) In order to obtain additional time extension to initiate closure of a CCR unit beyond the two years provided by paragraph (E)(2)(a) of this rule, the owner or operator of the CCR unit shall include with the demonstration required by paragraph (E)(2)(b) of this rule the following statement signed by the owner or operator or an authorized representative:
"I certify under penalty of law that I have personally examined and am familiar with the information submitted in this demonstration and all attached documents, and that, based on my inquiry of those individuals immediately responsible for obtaining the information, I believe that the submitted information is true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment."
(3) For purposes of this chapter, closure of the CCR unit has commenced if the owner or operator has ceased placing waste and completes any of the following actions or activities:
(a) Taken any steps necessary to implement the written closure plan required by paragraph (B) of this rule.
(b) Submitted a completed application for any required state or agency permit or permit modification.
(c) Taken any steps necessary to comply with any state or other agency standards that are a prerequisite, or are otherwise applicable, to initiating or completing the closure of a CCR unit.
(4) The timeframes specified in paragraphs (E)(1) and (E)(2) of this rule do not apply to any of the following owners or operators:

(a) Extensions of closure timeframes. The timeframes for completing closure of a CCR unit specified under paragraphs (F)(1) of this rule may be extended if the owner or operator can demonstrate that it was not feasible to complete closure of the CCR unit within the required timeframes due to factors beyond the facility's control. If the owner or operator is seeking a time extension beyond the time specified in the written closure plan as required by paragraph (B)(1) of this rule, the demonstration shall include a narrative discussion providing the basis for additional time beyond that specified in the closure plan. The owner or operator shall place each completed demonstration, if more than one time extension is sought, in the facility's operating record as required by paragraph (I)(3) of rule 3745-525-50 of the Administrative Code prior to the end of any two-year period. Factors that may support such a demonstration include the following:
(i) Complications stemming from the climate and weather, such as unusual amounts of precipitation or a significantly shortened construction season.
(ii) Time required to dewater a surface impoundment due to the volume of CCR contained in the CCR unit or the characteristics of the CCR in the unit.
(iii) The geology and terrain surrounding the CCR unit will affect the amount of material needed to close the CCR unit.
(iv) Time required or delays caused by the need to coordinate with and obtain necessary approvals and permits from a state or other agency.
(b) Maximum time extensions.
(i) CCR surface impoundments of forty acres or smaller may extend the time to complete closure by no longer than two years.
(ii) CCR surface impoundments larger than forty acres may extend the timeframe to complete closure of the CCR unit multiple times, in two-year increments. For each two-year extension sought, the owner or operator shall substantiate the factual circumstances demonstrating the need for the extension. No more than a total of five two-year extensions may be obtained for any CCR surface impoundment.
(iii) Except as provided in paragraph (F)(2)(b)(iv) of this rule, CCR landfills may extend the timeframe to complete closure of the CCR unit multiple times, in one-year increments. For each one-year extension sought, the owner or operator shall substantiate the factual circumstances demonstrating the need for the extension. No more than a total of two one-year extensions may be obtained for any CCR landfill.
(iv) CCR landfills that intersect with groundwater are eligible for the time extensions available to CCR units in paragraph (F)(2)(b)(ii) of this rule, provided the owner or operator documents that groundwater intersects the CCR unit in the closure plan.
(c) In order to obtain additional time extension to complete closure of a CCR unit beyond the times provided by paragraph (F)(1) of this rule, the owner or operator of the CCR unit shall include with the demonstration required by paragraph (F)(2)(a) of this rule the following statement signed by the owner or operator or an authorized representative:
"I certify under penalty of law that I have personally examined and am familiar with the information submitted in this demonstration and all attached documents, and that, based on my inquiry of those individuals immediately responsible for obtaining the information, I believe that the submitted information is true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment."
