  1. EAA Groundwater Conservation Plan October 23, 2012 By Javier Hernandez Conservation Supervisor

  2. The EAA’s GCP A Mission of Management , Protection, & Stewardship The Edwards Aquifer Authority’s Groundwater Conservation Plan (GCP) serves as a management and guidance document to assist permit holders in the preparation and implementation of individual GCPs

  3. Groundwater Conservation Rule Requirements A Mission of Management , Protection, & Stewardship • 715 Subchaper C, Groundwater Conservation and Reuse Rules requires individual Groundwater Conservation Plans (GCPs) and triennial status reports to be submitted by permit holders authorized to withdraw more than 3 acre-ft. • Municipal • Industrial • Irrigators with irrigation efficiency less than 60% • GCPs must utilize approved Best Management Practices (BMPs) as specified under the EAA’s GCP.

  4. GCP Status Reports A Mission of Management , Protection, & Stewardship

  5. Irrigation Conservation BMP Implementation A Mission of Management , Protection, & Stewardship • 646 permits/entities • 246 have no wells or not using • 394 irrigation assessments received meeting 60% • efficiency standard • In 2011 58 Irrigation GCP Status Reports mailed • 32 No longer irrigating • 18 Installed Center Pivots • 6 remain less than 60% efficient

  6. Industrial Conservation BMP Implementation A Mission of Management , Protection, & Stewardship • 185 permits/entities subject to rules • 65 No well or not in use

  7. Industrial Conservation BMP Compliance A Mission of Management , Protection, & Stewardship

  8. Municipal Conservation BMP Implementation A Mission of Management , Protection, & Stewardship • 99 permits/entities subject to rules. • 19 have no wells or not in use. • 47 are listed as purveyors and 33 non-purveyors

GCP Compliance A Mission of Management , Protection, & Stewardship • Submission of GCPs and Status Reports (on going) • Technical Review of municipal status reports • Notice of Deficiencies (NODs) • Industrial Users • Athletic Field Conservation (CCIS) • Sub-metering • Municipal Users • Water waste Prohibition • Conservation Pricing • Public and School Education Programs • Landscape Conservation Programs (surveys)

  11.

Perform landscape survey and develop a ET based irrigation schedule equal to no more than 80% of reference ET. 3. Install a dedicated landscape meter if landscape use is determined to exceed 20% of total use. If cost effective install and operate a Computer Controlled Irrigation System (CCIS) to achieve enhanced conservation. ISSUES
