RESTRICTION ON DRILLING OF WELLS NEAR CERTAIN RIVERS AND THEIR TRIBUTARIES. A person may not drill a well in the portion of the territory of a district that is located within 100 feet of the gradient boundary of the Frio, North Llano, Llano, West Nueces, Nueces, or San Saba River, or any tributary of one of those rivers, unless the well is: (1) exempt from the permitting requirements of Section 36.117(b)(1); and (2) drilled, completed, or equipped so that it is incapable of producing more than: (A) 10 gallons of groundwater per minute; or (B) five acre-feet of groundwater per year. SECTION 2. Section 36.117(b), Water Code, is amended to read as follows: (b) A district may not require any permit issued by the district for: (1) a well used solely for domestic use or for providing water for livestock, [or] poultry, or wildlife on a tract of land larger than 10 acres that is either drilled, completed, or equipped so that it is incapable of producing more than 25,000 gallons of groundwater a day; (2) the drilling of a water well used solely to supply water for a rig that is actively engaged in drilling or exploration operations for an oil or gas well permitted by the Railroad Commission of Texas provided that the person holding the permit is responsible for drilling and operating the water well and the well is located on the same lease or field associated with the drilling rig; or (3) the drilling of a water well authorized under a permit issued by the Railroad Commission of Texas under Chapter 134, Natural Resources Code, or for production from such a well to the extent the withdrawals are required for mining activities regardless of any subsequent use of the water.
