ARTBA Vice President of Regulatory Affairs Nick Goldstein visited House and Senate staffers January 14 along with a group of the Texas Department of Transportation (TxDOT) and representatives of Texas local governments to discuss the impacts of the U.S. Environmental Protection Agency’s (EPA) recent draft revisions to the ozone standard.  Specifically, EPA has proposed tightening the federal Clean Air Act (CAA) standard for ozone from the current 75 parts per billion (ppb) to between 65 and 70 ppb, with the option of going as low as 60 ppb.  On a national level, Goldstein stressed the consequences of this proposal would impair the transportation construction community as any of these options could increase the number of counties out of compliance with the CAA. If that were to occur, federal highway funds scheduled for use in noncomplying counties could be withheld. Goldstein also noted that while the EPA is required by law to review the ozone standard every five years, the agency is not required to tighten it.  Comments on the EPA draft rule are due March 17,
