(7) Cost of defending or pursuing liability claims against any party or state.
The fees established pursuant to this Section (d) of this Article may include incentives for source and volume reduction and may be based on the hazard of the waste. Notwithstanding anything to the contrary in this compact, or in any state constitution, statute, or regulation, to the extent that such fees are insufficient to pay for any costs associated with a regional facility, including all costs under Section (d) of this Article, all party states and any other state or states whose generators use the regional facility, shall share liability for all such costs. However, there shall be no recovery from the states under Section (d) of this Article until all available funds, payments, or in-kind services have been exhausted including:
(i) Designated low-level radioactive waste funds managed by the host state;
(ii) Payable proceeds of insurance or surety policies applicable to a regional facility;
(iii) Proceeds of reasonable collection efforts against the regional facility operator or operators; and
(iv) Payments from or in-kind services by generators.
In the event any regional facility operator files or has filed against it a bankruptcy proceeding, then for purposes of determining whether or not reasonable collection efforts have been undertaken, the filing of such proceedings, if not dismissed within sixty days of filing, shall be considered exhaustion of reasonable collection efforts with respect to such party. Recovery from the states under Section (d) of Article III upon satisfaction of the exhaustion of available funds, payments, or in-kind services shall not preclude any state from further recovery of its costs from a facility operator, insurer, or generator. During the period of time that such reasonable collection efforts or exhaustion of available funds, payments, or in-kind services occur, any applicable statutes of limitation with respect to claims against any other parties or states will be deemed tolled and will not run. All costs or liabilities shared by a state shall be shared proportionately by comparing the volume of the waste received at a regional facility from the generators of each state with the total volume of the waste received at a regional facility from all generators.
