Subject: NO2 NAAQS RIA

 

Hi, Heidi.

While cleaning up the track changes in the NO2 NAAQS RIA, we found some
boilerplate language in Chapter 1 (page 1-8) that has not been updated
in the past several RIAs.  Since you haven't seen this revision, Ron
asked me to forward this revised language to you.  We presume that this
will be a non-controversial revision.   

Original:

To streamline this RIA, this document refers to several previously
published documents, including three technical documents EPA produced to
prepare for promulgation of the NO2 NAAQS. The first was a Criteria
Document created by EPA’s Office of Research and Development
(published in 2007), which presented the latest available pertinent
information on atmospheric science, air quality, exposure, health
effects, and environmental effects of NO2. The second was an Integrated
Science Assessment (ISA) published in 2008 that evaluated the policy
implications of the key studies and scientific information contained in
the Criteria Document.  The third was a risk and exposure assessment
(REA) for various standard levels. The REA also includes staff
conclusions and recommendations to the Administrator regarding potential
revisions to the standards. 

Revised:

To streamline this RIA, this document refers to several previously
published documents, including two technical documents EPA produced to
prepare for promulgation of the NO2 NAAQS. The first was the Integrated
Science Assessment created by EPA’s Office of Research and Development
(U.S. EPA, 2007), which presented the latest available pertinent
information on atmospheric science, air quality, exposure, health
effects, and environmental effects of NO2. The second was a risk and
exposure assessment (REA) (U.S. EPA, 2008) for various standard levels.
The REA also includes staff conclusions and recommendations to the
Administrator regarding potential revisions to the standards. 

Thanks!
