H.B. No. 5660 proposes the dissolution of the El Milagro Management District, which was established by the Texas Commission on Environmental Quality on June 13, 2024. The bill mandates that the district's board must dissolve the district within 60 days of the Act's effective date, unless the district has outstanding bonded indebtedness. In such a case, the district will continue to exist solely for the purpose of winding up operations and discharging its debts. The board is required to utilize all available district funds to facilitate this process and ensure the repayment or defeasance of the bonded indebtedness as soon as practicable.

Additionally, the bill outlines that the legal notice regarding the introduction of this Act has been published and distributed to all necessary parties, including the governor and the Texas Commission on Environmental Quality, which has provided its recommendations. The Act is set to take effect immediately upon receiving a two-thirds vote from both houses of the legislature; otherwise, it will take effect on September 1, 2025. The bill also includes a provision stating that it will expire on September 1, 2027.
