(a) Applicability. This subchapter applies to owners and operators required to perform post-closure care as set out in Subchapter J of this chapter (relating to Closure and Post-Closure Care). Financial assurance shall be established and maintained for the duration of the post-closure care period as prescribed in §352.1241 of this title (relating to Post-Closure Care Requirements).
(b) Cost estimate. The owner or operator shall prepare and include with the application for registration, a written cost estimate in current dollars of the total cost of the 30-year post-closure care period to perform post-closure care requirements as prescribed in §352.1241 of this title. The cost estimate shall be based on the costs of hiring a third-party to conduct post-closure care maintenance. The most recent of these cost estimates approved by the executive director is termed as the post-closure care cost estimate.
(c) Mechanism. No more than 90 days after the executive director's approval of the registration, a financial assurance mechanism acceptable to the executive director must be submitted for the cost of post-closure care in an amount no less than the amount specified in the approved cost estimate. Financial assurance for post-closure care shall be demonstrated in compliance with Chapter 37, Subchapters A - D of this title (relating to General Financial Assurance Requirements; Financial Assurance Requirements for Closure, Post Closure, and Corrective Action; Financial Assurance Mechanisms for Closure, Post Closure, and Corrective Action; and Wording of the Mechanisms for Closure, Post Closure, and Corrective Action), except as indicated in §352.1111 of this title (relating to Exceptions).

At least 180 days before the end of the preceding post-closure care period, a written cost estimate in current dollars shall be prepared and submitted for the cost of continuing the post-closure care specified in the registration for the additional period specified in §352.1241 of this title. The cost estimate shall be based on the cost of hiring a third-party to perform the post-closure care. A financial assurance mechanism acceptable to the executive director shall be submitted for the continued post-closure care period in an amount approved by the executive director. Financial assurance for post-closure care shall be demonstrated in compliance with Chapter 37, Subchapters A - D of this title except as indicated in §352.1111 of this title.
(e) Executive director executed post-closure care. The executive director may use or direct the use of post-closure care funds to perform post-closure care at a coal combustion residuals unit when the executive director determines that a person has failed to perform the post-closure care required under Subchapter J of this chapter.
