The assessment shall include, at a minimum, the following: (1) Separate estimates of the aggregate projected costs of the remediation of unexploded ordnance, discarded military munitions, and munitions constituents at— (A) all operational ranges; and (B) all other defense sites. (2) A comprehensive plan for addressing the remediation of unexploded ordinance, discarded military munitions, and munitions constituents at defense sites, including an assessment of the funding required and the period of time over which such funding will be required. (3) An assessment of the technology currently available for the remediation of unexploded ordnance, discarded military munitions, and munitions constituents. (4) An assessment of the impact of improved technology on the cost of such remediation and a plan for the development and use of such improved technology. (b) REQUIREMENTS FOR COST ESTIMATES.— (1) The estimates of aggregate projected costs required by subsection (a)(1) shall— (A) be stated as a range of aggregate projected costs, including a low estimate and a high estimate; (B) set forth the differing assumptions underlying each such low estimate and high estimate, including— (i) any public uses for the operational ranges and other defense sites concerned that will be available after the remediation is completed; (ii) the extent of the remediation required to make the operational ranges and other defense sites concerned available for such uses; and (iii) the technologies to be applied to achieve such level of remediation; and (C) include, and identify separately, an estimate of the aggregate projected costs of the remediation of any ground water contamination that may be caused by unexploded ordnance, discarded military munitions, or munitions constituents at the operational ranges and other defense sites concerned. (2) The high estimate of the aggregate projected costs shall be based on the assumption that all unexploded ordnance, discarded military munitions, and munitions constituents at each operational range and other defense site will be addressed, regardless of whether there are any current plans to close the range or site or discontinue training at the range or site. (3) The estimate of the aggregate projected costs of remediation of ground water contamination under paragraph (1)(C) shall be based on a comprehensive assessment of the risk of such contamination and of the actions required to protect the ground water supplies concerned. (4) The standards for the report of liabilities of the Department of Defense shall not apply to the cost estimates required by subsection (a)(1). (c) INTERIM ASSESSMENT.— The report submitted to Congress under section 2706(a) of title 10, United States Code, in 2002 shall include the assessment required by subsection (a) to the extent that the information required to be provided as part of
