Obama needs to withdraw new ozone rules: senators
The Obama administration needs to withdraw its proposal for tougher ozone standards, these senators say. · CNBC

The Environmental Protection Agency's proposal to lower the National Ambient Air Quality Standard for ozone distorts the need for balance between environmental progress and economic growth.

While we have always stood in favor of cleaner air, the proposal to lower the current ozone standard of 75 parts per billion (ppb) could be the most expensive regulation in history and place undue burden on counties still working to comply with existing obligations, as well as impose costly regulations on new communities. EPA has proposed to set the standard between 65 and 70ppb and is taking comment on 60ppb. Should the standard be lowered to 60ppb, nearly the entire nation could be out of ozone compliance (or in "nonattainment") for the first time ever.

The Obama administration's aggressive push for swift changes to this rule is predicated on the health benefits of reduced ozone, or smog. However, many of these benefits will result from the reduction of other criteria pollutants, not ozone, which are already subject to other EPA regulations. Moreover, the 2008 standard of 75ppb is yet to be fully implemented; benefits continue to be achieved as the remaining 227 counties in nonattainment work to meet the standard.

Setting a new standard at this time is impractical and irresponsible, and both sides of the aisle agree. Kentucky's democrat Gov. Steven Beshear, who, incidentally, has proposed one of the most stringent state caps on carbon dioxide, has even written President Obama asking for withdrawal of the proposed ozone rule.

Our nation has made great strides in cleaning up the air we breathe. Air-pollution levels are at an all-time low. But 40 percent of Americans currently live in areas that haven't met the current ozone standard. By lowering the standard to 65ppb, EPA would then place 67 percent of U.S. land in nonattainment. Many of these areas, like Yellowstone National Park or high-elevation communities, have high levels of naturally occurring ozone, making them unable to comply with a lower standard.

While EPA is precluded from considering costs in setting a standard, the sheer economic magnitude of this rule is unprecedented and cannot be brushed under the rug. Even President Obama recognized this in 2011 when he pulled the plug mid-review on an attempt to similarly lower the ozone standard due to the "regulatory burdens and regulatory uncertainty" it would impose on our country.
