(b) A municipal water supplier that serves land described by Subsection (a) may petition the district in accordance with this section to convert the proportionate irrigation water right to the Rio Grande from irrigation use to municipal use with municipal priority of allocation under commission rules, for the use and benefit of the municipal supplier. (c) The municipal water supplier must file the petition with the district not later than January 1 after the expiration of two years after the date the plat or map was recorded under Subsection (a).

(d) The petition must identify by subdivision name or other sufficient description the land that the municipal water supplier supplies or has the right to supply potable water. (e) This section applies only to one subdivision of the land recorded under Subsection (a). This section does not apply to any further subdivision of the same property. Sec. 49.504. EFFECT OF MUNICIPAL WATER SUPPLIER'S FAILURE TO FILE A PETITION. (a) If a municipal water supplier does not file a petition under Section 49.503, the district may retain the water rights for use by the district or may declare the water as excess and contract for the sale or use of the water as determined by the district. (b) Before a district may contract for the sale or use of water for more than one year with a purchaser located outside of a county described by Section 49.502, the district must, for 90 days: (1) make the water available under the same terms to all municipal water suppliers located in those counties; and (2) advertise the offer to sell or contract for the use of the water by posting notice on: (A) any website of the Rio Grande Watermaster's Office; (B) any website of the Rio Grande Regional Water Authority; and (C) the official posting place for the district's board meetings at the district's office.

Sec. 49.505. CALCULATION OF PROPORTIONATE WATER RIGHTS. A district that receives a petition under Section 49.503 shall compute the proportionate amount of water rights to the Rio Grande. The proportionate amount of water rights is equal to the amount of irrigable acres of land in the subdivision multiplied by the lesser of: (1) 1.25 acre-feet per irrigable acre; or (2) the sum of all irrigation water rights owned by the district on September 1, 2007, as if the water rights had been converted to municipal use under applicable commission rules, divided by the total amount of irrigable acres of land in the district on September 1, 2007. Sec. 49.506. PROVISION OR CONVERSION OF PROPORTIONATE WATER RIGHTS BY DISTRICT. (a) Not later than the second anniversary of the date the municipal water supplier files a petition under Section 49.503: (1) a district shall provide the municipal water supplier with the proportionate water rights described by Section 49.505 from the district's existing water rights; or (2) a district shall, if the district does not have sufficient existing water rights: (A) apply for appropriate amendments to the district's water rights under commission rules to convert the proportionate water rights from irrigation use to municipal use with municipal priority of allocation; and (B) provide to the municipal water supplier the converted rights described by Section 49.505. (b) The district may continue to use the irrigation use water for district purposes until: (1) the commission approves the amendment to the district's water rights; or (2) the water is otherwise provided to the municipal water supplier. (c) A district that applies for appropriate amendments under Subsection (a)(2) shall provide the municipal water supplier with an estimate of the district's reasonable costs for the administrative proceedings. The district is not required to begin the proceedings until the municipal water supplier deposits the amount of the estimate with the district.

DUTY OF RIO GRANDE REGIONAL WATER AUTHORITY TO CALCULATE CURRENT MARKET VALUE. (a) The Rio Grand Regional Water Authority annually at its January meeting shall calculate the current market value by using the average price per acre-foot of municipal use water after conversion from irrigation use water to municipal use water with a municipal priority of allocation under commission rules of the last three purchases involving: (1) a municipal water supplier; (2) a party other than a municipal water supplier; and (3) at least 100 acre-feet of municipal use water, with municipal priority of allocation.

(b) Each municipal water supplier that has a certificate of convenience and necessity service area in the outer boundaries of a district shall file a map of the service area with the district. (c) The municipal water supplier shall update the map and forward the map to the district when changes are made. (d) A district periodically shall provide to a municipal water supplier that serves territory in the district a copy of the district's map showing the outer boundaries of the district.

On request, the district and a municipal water supplier shall provide the map free of charge to each other at least one time each year. If the district or municipal water supplier receives more than one request a year for a map, the district or municipal water supplier may charge a reasonable fee for the map. SECTION __. Subchapter O, Chapter 49, Water Code, as added by this Act, applies only to a subdivision for which a plat or map has been recorded in the office of the county clerk of a county on or after the effective date of this Act. A subdivision for which a plat or map was recorded before the effective date of this Act is covered by the law in effect on the date the plat or map was recorded, and the former law is continued in effect for that purpose.
