In this presentation, we will provide an update on recent changes to rules and regulations governing aquifer storage and recovery projects (ASR) in Colorado. We will discuss regulatory challenges, efficiencies and how hydrologic data collection and scientific analysis factor into ASR requirements. The 2018 Artificial Recharge Extraction Rules allow for different rules based on whether the aquifer is located in confined or unconfined conditions. The 2019 Designated Basin Rules will include ASR provisions that require baseline aquifer characterization, water level & water quality monitoring, and predictive modeling of recharged water movement. The US Environmental Protection Agency (EPA) has also increased stakeholder communications regarding Underground Injection Control (UIC) permitting related to ASR. In a recent public meeting, the EPA clarified UIC application requirements and the process to obtaining project approval. Although some may feel that these new regulatory requirements are overly restrictive, they are giving water providers legal and regulatory certainty to confidently develop underground water storage. We aim to show why successful planning, permitting, and implementation of ASR projects is likely to increase in coming years and how ASR will make rapid progress towards closing Colorado’s water storage gap.
