Edwards Aquifer Protection Program
Anyone who plans to build on the recharge, transition, or contributing zones of the Edwards Aquifer must first have an application including construction plans approved by the TCEQ. Personnel from the Edwards Aquifer Protection Program review these plans. If a plan is approved, the site is monitored for compliance.

The Edwards Aquifer regulated zones are present in eight Texas counties. The official boundaries were drawn on topographic base maps from the U.S. Geological Survey.

Our primary manual is Complying with the Edwards Aquifer RulesTechnical Guidance on Best Management Practices, RG-348,. There is a brief list of typographical errors in the manual. You may notify us of any other errors. We post an addendum that provides additional information that is approved for inclusion in the manual.
You may use our spreadsheet for permanent BMPs to calculate the required pollutant load reduction and sizing for permanent BMPs.
There are appendices to our manual that we call Optional Enhanced Measures for the Protection of Water Quality in the Edwards Aquifer. Last year we developed a supplemental guidance for quarry operations.
