While the national average falls states near the west coast are experiencing price increases—some spikes as high as 44.5 cents. Alaska Hawaii, California, Oregon, Washington and Nevada have experienced gas hikes due to recent refining and distribution issues. However, relief is on its way as the California Air Resources Board approved a resolution to some refining glitches and a waiver of the summer-blend gasoline requirements.
Due to the board's actions California experienced about eight cents of relief at the pump, but AAA reports California's average is still hovering its all-time high of $4.67 set seven days ago.
