Amend CSHB 846 by adding an appropriately numbered new SECTION to the bill and appropriately renumbering subsequent SECTIONS of the bill to read as follows: SECTION ____. Section 1.16(e), Chapter 626, Acts of the 73rd Legislature, Regular Session, 1993, is amended to read as follows: (e) To the extent water is available for permitting, the board shall issue the existing user a permit for withdrawal of an amount of water equal to the user's maximum beneficial use of water without waste during any one calendar year of the historical period. If a water user does not have historical use for a full year, then the authority shall issue a permit for withdrawal based on an amount of water that would normally be beneficially used without waste for the intended purpose for a calendar year. If the total amount of water determined to have been beneficially used without waste under this subsection exceeds the amount of water available for permitting, the authority shall adjust the amount of water authorized for withdrawal under the permits proportionately to meet the amount available for permitting. An existing irrigation user shall receive a permit for not less than two acre-feet a year for each acre of land the user actually irrigated using water from the Edwards Aquifer, either exclusively or commingled with other groundwater, in any one calendar year during the historical period. An existing user who has operated a well for three or more years during the historical period shall receive a permit for at least the average amount of water withdrawn annually during the historical period.
