Which Statement is the Truth about Background Pollution and the Clean Air Act?

May 7, 2014

Policy Relevant Background Ozone and EPAWhich is the Truth about Background Pollution?

 ►     “The Clean Air Act does not ask States to reduce background levels.”—Gina McCarthy, U.S. EPA Administrator (Congressional Testimony, April 2, 2014,  see link)


 ►    “Under the US Clean Air Act (CAA), regions are required to control the following contributing sources of ground level ozone: (1) US anthropogenic emissions (2) natural background ozone generated within the US, and (3) natural background ozone that is transported via the troposphere or stratosphere to the US from beyond its borders.”—San Joaquin Valley Air Quality Management District (April 17, 2014 Board Meeting, see link)

I’m sure Administrator McCarthy is like me in that at the end of the day, it isn’t about whether we are right or wrong, but that the truth is brought to light.

We must acknowledge the truth on this issue—and let that guide us.  The Clean Air Act requires States to reduce background if this is necessary to achieve attainment and protect human health.  (42 U.S.C. § 7407(a)).  In fact, States have been knowingly or unknowingly reducing background levels to some degree for years now by offsetting foreign pollution and the climate change penalty.

The world is changing.  We must change with it.  Time to transform the SIP process.  We can make it happen.
