House Republicans have called another hearing this week as part of their campaign against a California rail emissions rule.

The Transportation and Infrastructure Subcommittee on Railroads, Pipelines and Hazardous Materials will question Heather Arias, head of the California Air Resource Board’s Transportation and Toxins Division.

The rule, which went into effect in January, goes further than federal standards. However, state regulators cannot enforce it until EPA signs off on it, and Republicans have been pressuring EPA to kill the rulemaking.


“The CARB Rule fails any meaningful cost-benefit analysis,” wrote Transportation and Infrastructure Chair Sam Graves (R-Mo.) and subcommittee Chair Troy Nehls (R-Texas) in April.
