(B) a summary of the proposed action to be taken;
(C) the name, telephone number, and address of the person to whom questions or requests for additional information may be submitted; and
(D) information on how the public may submit comments.
(10) The regional water planning group may amend the regional water plan after the plan has been approved by the board. If, after the regional water plan has been approved by the board, the plan includes a water management strategy or project that ceases to be feasible, the regional water planning group shall amend the plan to exclude that water management strategy or project and shall consider amending the plan to include a feasible water management strategy or project in order to meet the need that was to be addressed by the infeasible water management strategy or project. For purposes of this subdivision, a water management strategy or project is considered infeasible if the proposed sponsor of the water management strategy or project has not taken an affirmative vote or other action to make expenditures necessary to construct or file applications for permits required in connection with the implementation of the water management strategy or project under federal or state law on a schedule that is consistent with the completion of the implementation of the water management strategy or project by the time the water management strategy or project is projected by the regional water plan or the state water plan to be needed. Subdivisions (1)-(9) apply to an amendment to the plan in the same manner as those subdivisions apply to the plan.
(11) This subdivision applies only to an amendment to a regional water plan approved by the board. This subdivision does not apply to the adoption of a subsequent regional water plan for submission to the board as required by Subsection (i). Notwithstanding Subdivision (10), the regional water planning group may amend the plan in the manner provided by this subdivision if the executive administrator makes a written determination that the proposed amendment qualifies for adoption in the manner provided by this subdivision before the regional water planning group votes on adoption of the amendment. A proposed amendment qualifies for adoption in the manner provided by this subdivision only if the amendment is a minor amendment, as defined by board rules, that will not result in the overallocation of any existing or planned source of water, does not relate to a new reservoir, and will not have a significant effect on instream flows or freshwater inflows to bays and estuaries. If the executive administrator determines that a proposed amendment qualifies for adoption in the manner provided by this subdivision, the regional water planning group may adopt the amendment at a public meeting held in accordance with Chapter 551, Government Code. The proposed amendment must be placed on the agenda for the meeting, and notice of the meeting must be given in the manner provided by Chapter 551, Government Code, at least two weeks before the date the meeting is held. The public must be provided an opportunity to comment on the proposed amendment at the meeting.
(12) Each regional water planning group and any committee or subcommittee of a regional water planning group are subject to Chapters 551 and 552, Government Code.
(i) The regional water planning groups shall submit their adopted regional water plans to the board by January 5, 2001, for approval and inclusion in the state water plan. In conjunction with the submission of regional water plans, each planning group should make legislative recommendations, if any, to facilitate more voluntary water transfers in the region or for any other changes that the members of the planning group believe would improve the water planning process. Subsequent regional water plans shall be submitted at least every five years thereafter, except that a regional water planning group may elect to implement simplified planning, no more often than every other five-year planning cycle, and in accordance with guidance to be provided by the board, if the group determines that, based on its own initial analyses using updated groundwater and surface water availability information, there are no significant changes to the water availability, water supplies, or water demands in the regional water planning area. At a minimum, simplified planning will require updating groundwater and surface water availability values in the regional water plan, meeting any other new statutory or other planning requirements that come into effect during each five-year planning cycle, and formally adopting and submitting the regional water plan for approval. Public participation for revised regional plans shall follow the procedures under Subsection (h).
(j) The board may provide financial assistance to political subdivisions under Subchapters E and F of this chapter, Subchapters C, D, E, F, J, O, Q, and R, Chapter 15, and Subchapters D, I, K, and L, Chapter 17, for water supply projects only if:
(1) the board determines that the needs to be addressed by the project will be addressed in a manner that is consistent with the state water plan;
(2) beginning January 5, 2002, the board:
(A) has approved a regional water plan as provided by Subsection (i), and any required updates of the plan, for the region of the state that includes the area benefiting from the proposed project; and
(B) determines that the needs to be addressed by the project will be addressed in a manner that is consistent with that regional water plan; and
(3) the board finds that the water audit required under § 16.0121 has been completed and filed.
(k) The board may waive the requirements of Subsection (j) of this section if the board determines that conditions warrant the waiver.
(l) A political subdivision may contract with a regional water planning group to assist the regional water planning group in developing or revising a regional water plan.
(m) A cause of action does not accrue against a regional water planning group, a representative who serves on the regional water planning group, or an employee of a political subdivision that contracts with the regional water planning group under Subsection (l) for an act or omission in the course and scope of the person’s work relating to the regional water planning group.
(n) A regional water planning group, a representative who serves on the regional water planning group, or an employee of a political subdivision that contracts with the regional water planning group under Subsection (l) is not liable for damages that may arise from an act or omission in the course and scope of the person’s work relating to the regional water planning group.
(o) The attorney general, on request, shall represent a regional water planning group, a representative who serves on the regional water planning group, or an employee of a political subdivision that contracts with the regional water planning group under Subsection (l) in a suit arising from an act or omission relating to the regional water planning group.
(p) If a groundwater conservation district files a petition with the development board stating that a conflict requiring resolution may exist between the district’s approved management plan developed under § 36.1071 and an approved state water plan, the development board shall provide technical assistance to and facilitate coordination between the district and the involved region to resolve the conflict. Not later than the 45th day after the date the groundwater conservation district files a petition with the development board, if the conflict has not been resolved, the district and the involved region shall mediate the conflict. The district and the involved region may seek the assistance of the Center for Public Policy Dispute Resolution at The University of Texas School of Law or an alternative dispute resolution system established under Chapter 152, Civil Practice and Remedies Code, in obtaining a qualified impartial third party to mediate the conflict. The cost of the mediation services must be specified in the agreement between the parties and the Center for Public Policy Dispute Resolution or the alternative dispute resolution system. If the district and the involved region cannot resolve the conflict through mediation, the development board shall resolve the conflict not later than the 60th day after the date the mediation is completed as provided by Subsections (p-1) and (p-2).
(p-1) If the development board determines that resolution of the conflict requires a revision of an approved regional water plan, the development board shall suspend the approval of that plan and provide information to the regional water planning group. The regional water planning group shall prepare any revisions to its plan specified by the development board and shall hold, after notice, at least one public hearing at some central location readily accessible to the public within the regional water planning area. The regional water planning group shall consider all public and development board comments, prepare, revise, and adopt its plan, and submit the revised plan to the development board for approval and inclusion in the state water plan.
(p-2) If the development board determines that resolution of the conflict requires a revision of the district’s approved groundwater conservation district management plan, the development board shall provide information to the district. The groundwater district shall prepare any revisions to its plan based on the information provided by the development board and shall hold, after notice, at least one public hearing at some central location readily accessible to the public within the district. The groundwater district shall consider all public and development board comments, prepare, revise, and adopt its plan, and submit the revised plan to the development board.
(p-3) If the groundwater conservation district disagrees with the decision of the development board under Subsection (p), the district may appeal the decision to a district court in Travis County. Costs for the appeal shall be set by the court hearing the appeal. An appeal under this subsection is by trial de novo.
(p-4) On the request of the involved region or groundwater conservation district, the development board shall include discussion of the conflict and its resolution in the state water plan that the development board provides to the governor, the lieutenant governor, and the speaker of the house of representatives under § 16.051(e).
