"Clean air rules may wait till after election":
With a mid-term congressional election looming, the Obama administration is expected to delay issuing controversial air pollution rules that the Republican opposition has characterized as economic poison.
The U.S. Environmental Protection Agency had planned to issue the nation's strictest-ever standards for ground-level ozone this week. The new standards would cost states and businesses anywhere from $19 billion to $90 billion to implement in 2020 alone, the EPA has estimated.
It could be cheaper with incentive-based policy: sounds like implementation in North Carolina will include uniform technological standards.
