This document summarizes recent legislation and rules in Texas regarding aquifer storage and recovery (ASR) projects. The key points are: 1) House Bill 655 and rules by the Texas Commission on Environmental Quality (TCEQ) in 2016 have expedited the ASR permitting process, allowing different types of authorizations and clarifying notice requirements. 2) The new rules require compliance with federal drinking water standards but no stricter requirements, and they establish testing, metering and reporting standards for ASR projects. 3) There are still many uncertainties that are not expressly addressed, including liability, protecting groundwater plumes, and regulation of different water sources. Applicants must demonstrate the requirements themselves
