SUPPLEMENTARY INFORMATION: On July 1, 2025 (90 FR 28086), PHMSA
published a DFR amending its regulations at 49 CFR part 192 to
incorporate by reference the second editions of API RPs 1170 (``Design
and Operation of Solution-mined Salt Caverns Used for Natural Gas
Storage'') and 1171 (``Functional Integrity of Natural Gas Storage in
[[Page 47623]]
Depleted Hydrocarbon Reservoirs and Aquifer Reservoirs''). Reference to
the second edition of API RP 1170 will replace existing references
within sections 192.7 and 192.12 to API Recommended Practice 1170,

PHMSA issued the DFR under the procedures set forth at 49 CFR
190.339. In accordance with those provisions, PHMSA stated in the DFR
that if no adverse comments were received, the DFR would become final
and effective on January 1, 2026. PHMSA did not receive any comments
that warranted withdrawal of the DFR; therefore, this rule will become
effective as scheduled.

authority designated in 49 CFR 1.97.
