(a) Notwithstanding any other provision of law, Act of the legislature or the executive branch, or any other agreement, the initial payment of $12.5 million due from each nonhost party state under Section 5.01 of the compact established under § 403.006 is due not later than November 1, 2003. In accordance with Section 7.01 of the compact, the host state establishes the following terms and conditions for a state to become a party state to the compact after January 1, 2011:
(1) the state must make an initial payment of half of the total amount due to the host state under Subsection (b) on the later of September 1, 2011, or the date the state becomes a party state; and
(2) the state must pay the remainder of the amount owed under Subsection (b) on the later of the date of the opening of the compact waste disposal facility or the date the facility first accepts waste from the state.
(b) Each state that becomes a party state:

(2) on or after September 1, 2018, and before September 1, 2023, shall contribute $50 million to the host state, including the initial payment under Subsection (a)(1).

(c) The requirements of this section apply to a state that becomes a party state after January 1, 2011, regardless of whether the state had previously been a party to the compact. A state that has withdrawn as a party state shall pay the previously committed fee of $25 million in addition to the fees set in Subsection (b).
(d) A payment made under this section may not be refunded, even if a party state withdraws from the compact.
(e) For the purposes of calculating the amount of a payment required under Section 4.05(5) of the compact, the amount of a payment under this section is considered to be a payment under Article V of the compact.
