(a) The RWPGs shall submit their adopted RWPs to the Board every five years on a date to be disseminated by the EA, as modified by subsection (g)(2) of this section, for approval and inclusion in the State Water Plan.     
      (b) Prior to the adoption of the RWP, the RWPGs shall submit concurrently to the EA and the public an IPP. The IPP submitted to the EA must be in the electronic and paper format specified by the EA. Each RWPG must certify that the IPP is complete and adopted by the RWPG. In the instance of a recommended WMS proposed to be supplied from a different RWPA, the RWPG recommending such strategy shall submit, concurrently with the submission of the IPP to the EA, a copy of the IPP, or a letter identifying the WMS in the other region along with an internet link to the IPP, to the RWPG associated with the location of such strategy.     
      (c) The RWPGs shall distribute the IPP in accordance with §357.21(h)(7) of this title (relating to Notice and Public Participation).     
      (d) Within 60 days of the submission of IPPs to the EA, the RWPGs shall submit to the EA, and the other affected RWPG, in writing, the identification of potential Interregional Conflicts by:      
        (1) identifying the specific recommended WMS from another RWPG's IPP;       
        (2) providing a statement of why the RWPG considers there to be an Interregional Conflict; and       
        (3) providing any other information available to the RWPG that is relevant to the Board's decision.       
      (e) The RWPGs shall seek to resolve conflicts with other RWPGs and shall promptly and actively participate in any Board sponsored efforts to resolve Interregional Conflicts.     
      (f) The RWPGs shall solicit, and consider the following comments when adopting an RWP:      
        (1) the EA's written comments, which shall be provided to the RWPG within 120 days of receipt of the IPP; and       
        (2) any written or oral comments received from any federal agency, Texas state agency, or the public after the first public hearing notice is published until at least 60 days after the public hearing is held pursuant to §357.21(h) of this title.       
        (3) The RWPGs shall revise their IPPs to incorporate negotiated resolutions or Board resolutions of any Interregional Conflicts into their final adopted RWPs.       
        (4) In the event that the Board has not resolved an Interregional Conflict sufficiently early to allow an involved RWPG to modify and adopt its final RWP by the statutory deadline, all RWPGs involved in the conflict shall proceed with adoption of their RWP by excluding the relevant recommended WMS and all language relevant to the conflict and include language in the RWP explaining the unresolved Interregional Conflict and acknowledging that the RWPG may be required to revise or amend its RWP in accordance with a negotiated or Board resolution of an Interregional Conflict.       
      (g) Submittal of RWPs. RWPGs shall submit the IPP and the adopted RWPs and amendments to approved RWPs to the EA in conformance with this section.      
        (1) RWPs shall include:                  (A) The technical report and data prepared in accordance with this chapter and the EA's specifications;                   (B) An executive summary that documents key RWP findings and recommendations;                   (C) Documentation of the RWPG's interregional coordination efforts; and                   (D) A copy of the EA's comments on the IPP and summaries of all written and oral comments received pursuant to subsection (f) of this section, with a response by the RWPG explaining how the plan was revised or why changes were not warranted in response to written comments received under subsection (f) of this section.         
        (2) RWPGs shall submit RWPs to the EA according to the following schedule:                  (A) IPPs are due every five years on a date disseminated by the EA unless an extension is approved, in writing, by the EA.                   (B) Prior to submission of the IPP, the RWPGs shall upload all required data, metadata and all other relevant digital information supporting the plan to the Board's State Water Planning Database. All changes and corrections to this information must be entered into the Board's State Water Planning Database prior to submittal of a final adopted plan.                   (C) The RWPG shall transfer copies of all data, models, and reports generated by the planning process and used in developing the RWP to the EA. To the maximum extent possible, data shall be transferred in digital form according to specifications provided by the EA. One copy of all reports prepared by the RWPG shall be provided in digital format according to specifications provided by the EA. All digital mapping shall use a geographic information system according to specifications provided by the EA. The EA shall seek the input from the State Geographic Information Officer regarding specifications mentioned in this section.                   (D) Adopted RWPs are due to the EA every five years on a date disseminated by the EA unless, at the discretion of the EA, a time extension is granted consistent with the timelines in Texas Water Code §16.053(i).                   (E) Once approved by the Board, RWPs shall be made available on the Board website.         
      (h) Upon receipt of an RWP adopted by the RWPG, the Board shall consider approval of such plan based on the following criteria:      
        (1) verified adoption of the RWP by the RWPG; and       
        (2) verified incorporation of any negotiated resolution or Board resolution of any Interregional Conflicts, or in the event that an Interregional Conflict is not yet resolved, verified exclusion of the relevant recommended WMS and all language relevant to the conflict.       
      (i) Approval of RWPs by the Board. The Board may approve an RWP only after it has determined that the RWP complies with statute and rules.     
      (j) The Board shall consider approval of an RWP that includes unmet municipal Water Needs provided that the RWPG includes adequate justification, including that the RWP:      
        (1) documents that the RWPG considered all potentially feasible WMSs, including Drought Management WMSs and contains an explanation why additional conservation and/or Drought Management WMSs were not recommended to address the need;       
        (2) describes how, in the event of a repeat of the Drought of Record, the municipal WUGs associated with the unmet need shall ensure the public health, safety, and welfare in each Planning Decade that has an unmet need; and       
        (3) explains whether there may be occasion, prior to development of the next IPP, to amend the RWP to address all or a portion of the unmet need.       
      (k) Board Adoption of State Water Plan. RWPs approved by the Board pursuant to this chapter shall be incorporated into the State Water Plan as outlined in §358.4 of this title (relating to Guidelines).
