The UIC Program is responsible for regulating the construction, operation, permitting, and closure of injection wells that place fluids underground for storage or disposal.
This site provides information for owners and operators of injection wells and state regulators on how to safely operate injection wells to prevent contamination of underground drinking water resources.
See: A searchable database covering all EISs filed with EPA since January 2004.

State UIC Programs have primary enforcement responsibility (or primacy) once their UIC programs have been approved by EPA. The UIC Program Primacy page provides information about the requirements for obtaining primacy and which states have been granted this authority.
The UIC Program requirements were developed by EPA and designed to be adopted by states, territories, and tribes. States, territories, and tribes can submit an application to EPA to obtain primary enforcement responsibility, or primacy.
Agencies that have been granted this authority oversee the injection activities in their states. The requirements for primacy programs are outlined in the UIC regulations at 40 CFR Part 145.
