This component contains all data presented in the Aquifer Exemptions Map application. To download this data, please see the AquiferExemptions_2018.gdb file. 

 The Aquifer Exemptions Map application presents a series of maps allows users to find locations of aquifer exemptions approved for exemption under the Safe Drinking Water Act. The map shows the approved aquifer exemption boundaries, when available, in two dimensions, and information such as the depth of injection, local geology, and injected fluid characteristics. The map and accompanying data can be used by states, businesses, communities, and others to view exempted aquifers in the United States, see accompanying aquifer exemption data like depth of injection, local geology, and injected fluid characteristics, and can assist with Underground Injection Control (UIC) permit applications and approvals. The map consolidates information that was previously only available on paper and/or in databases at the state level and will assist EPA and states in maintaining consistent exemption data across this nation. 

Aquifer exemptions in California are not shown on the maps. California is engaged in a process to digitize existing exemption locations and is also currently reviewing numerous requests for new or expanded aquifer exemptions that they expect to submit to EPA Region 9 for review. As this work progresses, the aquifer exemptions in California will be added to the national dataset.
