Current through Reg. 50, No. 13; March 28, 2025

(a) The owner or operator shall provide a detailed written cost estimate, in current dollars, of the cost of hiring a third party to conduct post-closure care activities for the municipal solid waste unit, in accordance with the post-closure care plan. The post-closure care cost estimate used to demonstrate financial assurance in subsection (b) of this section shall account for the total costs of conducting post-closure care for the largest area that could possibly require post-closure care in the year to follow, including annual and periodic costs as described in the post-closure care plan over the entire post-closure care period. The cost estimate for financial assurance shall be submitted with any new permit application, with any application for a permit transfer, and as a modification for all existing municipal solid waste permits that remain in effect after October 9, 1993.

(1) An increase in the post-closure care cost estimate and the amount of financial assurance provided under subsection (b) of this section shall be made if changes in the post-closure care plan or the unit conditions increase the maximum costs of post-closure care.

(2) A reduction in the post-closure care cost estimate and the amount of financial assurance provided under subsection (b) of this section may be allowed if the cost estimate exceeds the maximum costs of post-closure care remaining over the post-closure care period and the owner or operator has provided written notice to the executive director of the detailed justification for the reduction of the post-closure cost estimate and the amount of financial assurance. The owner or operator may request a reduction in the cost estimate and the financial assurance as a permit modification.

(b) The owner or operator of any municipal solid waste landfill unit shall establish financial assurance for the costs of post-closure care of the unit in accordance with Chapter 37, Subchapter R of this title (relating to Financial Assurance for Municipal Solid Waste Facilities). Continuous financial assurance coverage for post-closure care shall be provided until the facility is officially released in writing by the executive director from the post-closure care period in accordance with all requirements of the post-closure care plan.
