AUTHOR'S / SPONSOR'S STATEMENT OF INTENT

S.B. 2379 addresses aquifer storage and recovery (ASR) projects in certain areas of the Edwards Aquifer. Under the rules of the Texas Commission on Environmental Quality (TCEQ), no waste injection wells can be authorized if the wells transect or terminate in the Edwards Aquifer in Williamson County. This prohibition applies to recently proposed ASR injection wells that would transect the Edwards Aquifer to inject treated surface water into deeper geologic formations underlying the Edwards Aquifer for purposes of providing much-needed water supplies to this high-growth area of the state. The purpose of the bill is to maintain the current prohibition on waste injection wells, while authorizing TCEQ to approve an ASR project that includes ASR injection wells that will transect the Edwards Aquifer in portions of Williamson County for injection of water into deeper geologic formations underlying the Edwards Aquifer.

As proposed, S.B. 2379 amends current law relating to the definition of the Edwards Aquifer for the purposes of an aquifer storage and recovery project.
