Underground Injection Control
National and Regional Contacts
State UIC ProgramsIn Region 6, which includes Texas, Louisiana, Arkansas, Oklahoma, and New Mexico, each State has received EPA's approval and directly implements the program in their respective jurisdictions. In each State except Louisiana, implementation of the UIC program is split between two state agencies. To see the contact information for any of these state agencies and the portion of the program it administers, click on the state link above. Region 6 retains an oversight capacity on these state programs. Underground Injection Control (UIC) Direct Implementation (Tribes) (Class II Wells)In Region 6, all of the states retain the authority to implement the UIC program; however, EPA retains the authority to implement the UIC program on tribal lands within these states with the exception of the Five Civilized Tribes in Oklahoma. Currently EPA is actively issuing UIC permits in Oklahoma and New Mexico with the main permitting activity principally in the Osage Mineral Reserve in Oklahoma. In New Mexico, the EPA issues the permits for activities on the Ute Mountain Ute and Jicarilla Apache Reservations in Rio Arriba and San Juan counties. For tribal jurisdictions in Texas, Louisiana, or Arkansas, EPA retains the authority to issue these UIC permits. Underground Injection Control (UIC) Land BanThis program operates under the authority of the Resource Conservation and Recovery Act (RCRA). In 1984 the Hazardous and Solid Waste Amendments (HSWA) to RCRA added significant new restrictions on the disposal of hazardous waste. Under these amendments, land disposal of hazardous wastes, which includes Class I hazardous waste injection wells, is prohibited unless:
Restrictions on specific hazardous wastes have been phased in over time: for some wastes they became effective as early as August 8, 1988; other hazardous wastes are still being added to the list. Region 6 Underground Injection Control (UIC) EnforcementPublic Notices |
