ATTACHMENT "A" §3.05. Water Availability Demonstrations Using Individual Private Water Wells Producing Local Groundwater In addition to the requirements outlined in §715.3.02, Applicants requesting approval to utilize one or more individual private water wells using Local Groundwater to serve the proposed development shall construct at least two wells (one test well and one monitor well). Use of existing wells will be permitted if the wells fully meet these regulations. Well analyses shall be performed by a Texas licensed professional engineer or Texas licensed professional geoscientist, qualified to perform the hydrogeological testing, geophysical well logging and aquifer pump testing. The following information shall be provided to Commissioners Court for each well tested. (A) Identify the hydrogeologic formation by well driller's log and approved geophysical logging methods. Provide a map and list of all known wells within 1,000 feet of the proposed subdivision boundaries (or a distance where measurable drawdown effects from the proposed subdivision well are expected). Each well is to be located by latitude and longitude. (B) The Certification of Groundwater Availability For Platting Form as required by the TCEQ rules on Groundwater Availability Certification for Platting at 30 Tex. Admin. Code Section 230.3. The Department shall require an applicant to submit any engineering calculations, studies or other data supporting the statements contained in the Certification of Groundwater Availability For Platting Form. Individuals marketing the development shall provide each purchaser or renter with a statement describing the extent to which water and wastewater service will be made available, and how and when such service will be made available. §3.06. Additional Requirements for Subdivisions Served by Individual Water Wells Producing Local Groundwater in Priority Groundwater Management Areas Applicants requesting approval to utilize individual private water wells producing Local Groundwater to serve proposed new development in a Priority Groundwater Management Area, as that term is defined by the Texas Commission on Environmental Quality, shall be subject to the following additional requirements: (A) The person preparing the groundwater availability certification shall document that they obtained available information on historical water levels and known water wells from the applicable Groundwater Conservation District. (B) The person preparing the groundwater availability certification shall perform a walking receptor survey around the perimeter of the Subject Property to identify the visual location of apparent undocumented water wells and to visually confirm the presence of documented water wells within five hundred (500) feet of the boundaries of the subject property. (C) The person preparing the groundwater availability certification shall estimate the average annual recharge (per acre) in the vicinity of the Subject Property using a Groundwater Availability Model (GAM) reviewed and approved by the Texas Water Development Board.
