Chicago is currently a non-attainment area.
That means we don’t meet National Ambient Air Quality Standards (NAAQS) “for pollutants considered harmful to public health and the environment” (read more), standards which are regulated by the United States Environmental Protection Agency (EPA). Six pollutants are measured across the country (note 1). We currently don’t attain standards for particle pollution, specifically Particulate Matter 2.5; they’re particles smaller than 2.5 micrometers and “referred to as ‘fine’ particles and are believed to pose the greatest health risks”. Additionally, we’re a maintenance area for the 8-hour ozone standard. It is this designation that puts a large portion of the region’s transportation funding risk.
The Chicago Metropolitan Agency for Planning (CMAP), the region’s official regional planning organization, reported last week that the EPA may remove our designation of “non attainment”, putting at risk about $90 million per year in federal grants from the Congestion Mitigation and Air Quality (CMAQ) program. This designation would be based on revised air quality standards (note 2) and 2008-2010 data, even though 2011 data has been gathered and certified by the Illinois EPA. Our attainment level would be lowered to maintenance for the 8-hour ozone standard.
CMAQ funds a lot of projects that we’ve written about: bike sharing, bike lanes, train stations, etc. (read all of our articles about the program). My three-year job at the Chicago Department of Transportation was paid for my CMAQ funding, as are many of the positions at the Bicycle Program. The region can still receive funding as a maintenance area, but at a reduced level.
The policy update on the CMAP website explains (A) why the new ozone standard is wrong:
An updated ozone standard of 75 parts per billion (ppb) promulgated in 2008 has been controversial and generated several lawsuits. A scientific advisory panel, charged with reviewing health impact studies and recommending the level of the standard to U.S. EPA, later suggested a more stringent level of between 60 and 70 ppb. Implementation of the standard has therefore been delayed until now. [See note 2 for more information]
(B) that the Chicago region (note 3) will likely again become non-attainment in a 2013 review, possibly restarting eligibility for 2015:
First of all, with exceedances in 2011 and an update of the standard scheduled for 2013, it is inevitable that the region will revert to a non-attainment status. There is little to be gained by declaring attainment for a relatively short period of time.
and (C), that we breached the 2008 standards numerous times in 2011:
Complicating the issue is the fact that our region experienced numerous exceedances of the 2008 air quality standard in 2011. If that year’s data is included in making the determination, then the region would not be in attainment of the 2008 standard and would continue to receive CMAQ funding. The IEPA has already certified the 2011 monitoring data and forwarded it to U.S. EPA, requesting that it be considered when making their initial designation. However, after replying to IEPA in a December 9 letter, U.S. EPA has now announced its preliminary designations that assert northeastern Illinois to be in attainment based on the 2008 standard.
The policy update notes that while the region may become an attainment area for the 8-hour ozone standard, it doesn’t note that we are a non-attainment area for PM2.5, as I explained in the beginning. I’m looking into this, specifically whether or not the EPA will also make the region an attainment or maintenance area for PM2.5 as well as ozone.

(2) From the New York Times, September 2, 2011:
The E.P.A., following the recommendation of its scientific advisers, had proposed lowering the so-called ozone standard of 75 parts per billion, set at the end of the Bush administration, to a stricter standard of 60 to 70 parts per billion. The change would have thrown hundreds of American counties out of compliance with the Clean Air Act and required a major enforcement effort by state and local officials, as well as new emissions controls at industries across the country.
Lisa P. Jackson, the E.P.A. administrator, has pushed hard for a tougher ozone standard, telling associates that it was one of the most important regulatory initiatives she would handle during her tenure. But she found herself on the losing end of a fight with top White House economic and political advisers, who were persuaded by industry arguments that the 2008 ozone rule was due to be reviewed in two years anyway and who were concerned about the impact on state, local and tribal governments that would bear much of the burden of compliance.”
