OMB agrees with
EPA's assertion that the study results are not generalizable to the
US population. OMB is concerned with a number of issues raised by
the methodology used in this ICR. In future ICR submissions that
involve an epidemiological study to identify and evaluate exposure
to and effects of air pollutants on human health, EPA should
address the key points enumerated below. 1. Describe in detail how
the research will contribute to the scientific literature and
advance EPA's understanding of health effects and exposure to fine
PM, VOCx and/or other air pollutants. In addition, specific
attention should be given to addressing hte practical utility of
the data generated for performing risk assessments. 2. Address how
the potential confounding factors of indoor air quality and
biological contaminants will be accounted for in any study relying
on outdoor ambient air quality measures. 3. Justify the failure to
include monitoring for ozone and sulfur dioxide, or any other key
pollutants that are known to affect pulmonary function. 4. Provide
a description of potential complications from using statistically
aggregated data and a justification for the choice of such
methodology over an individual level cohort study.
