Providing congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "California State Motor Vehicle and Engine and Nonroad Engine Pollution Control Standards; The "Omnibus" Low NOX Regulation; Waiver of Preemption; Notice of Decision".

HJRES 89 is a congressional disapproval resolution that blocks an Environmental Protection Agency (EPA) rule concerning California's vehicle and engine pollution standards. The resolution specifically targets the EPA's "Omnibus Low NOX Regulation" and waiver of preemption, which would have allowed California to enforce stricter emissions rules. By disapproving this rule under Chapter 8 of Title 5 U.S. Code, Congress has nullified the EPA's action, meaning the regulation will have no legal effect. This directly affects the EPA's authority to approve California's state-level pollution control standards for motor vehicles.
