Sen. Barbara Boxer says EPA Administrator Stephen Johnson is "ducking" a meeting with her as the deadline nears for the agency to decide whether to allow California to implement its landmark tailpipe emissions law.
The Environmental Protection Agency's self-imposed deadline for making the decision is the end of December.
Boxer told reporters Tuesday that she's been trying to meet with Johnson to see where things stand but so far he's refused.
Boxer also said she has "little hope" that EPA will grant the waiver required to allow California to slash greenhouse gas emissions from cars and trucks. More than a dozen other states plan to enact the same limits if California gets the waiver.
