## Abstract

The Environmental Protection Agency (EPA) is issuing a final rule to amend its Underground Injection Control (UIC) regulations to reflect the transfer of the state of Idaho's UIC program for Class II injection wells from Idaho to the EPA. Idaho submitted a formal request that the EPA transfer and directly implement the Class II UIC Program. Idaho will maintain primacy for Class I, III, IV, and V injection wells pursuant to their program approved by the EPA in 1985.
