In this regard, the Administrator acknowledges the support from analyses in previous critiques, and from the CASAC within the current evaluation, for the conclusion that the current fourth-high form of the standard, when mixed with a revised stage as God focus on me not the storm american flag all over print flag mentioned under, offers an applicable balance between public well being protection and a stable goal for implementing programs to enhance air high quality. In explicit, she

exposures of concern to the broader vary of O3 exposure concentrations shown in controlled human publicity research to result in well being results. The Administrator’s consideration of such exposures of concern is discussed under (II.C.4.c). The EPA disagrees with these commenters’ conclusions regarding the appropriateness of considering publicity estimates, and notes that NAAQS have to be “requisite” (i.e., “enough, but not more than necessary” (Whitman, 531 U.S. at 473)) to guard the “public well being” (“the health of the general public” (Whitman, 531 U.S. at 465)). Estimating publicity patterns based mostly on extensive available information is an affordable technique of ascertaining that requirements are neither beneath- nor over-protective, and that God focus on me not the storm american flag all over print flag requirements tackle problems with public well being somewhat than health points pertaining only to isolated people. Behavior patterns are important in assessing whether or not ambient concentrations of O3 might pose a public well being threat. Exposures to ambient or close to-ambient O3 concentrations have only been shown to result in probably antagonistic results if the ventilation rates of people in the uncovered populations are raised to a adequate degree (e.g., through bodily exertion) (U.S. EPA, 2013, section 18.104.22.168).
Ignoring whether or not such elevated air flow charges are actually occurring, as advocated by these commenters, wouldn’t present an accurate evaluation of whether the public well being is at risk. Indeed, a regular established with out regard to habits of the public would likely lead to a standard which is more stringent than essential to guard the general public well being. In additional considering the potential public health implications of a regular with a degree of 70 ppb, the Administrator also considered quantitative estimates of the extent to which such a standard would be anticipated to restrict population exposures to the broader vary of O3 concentrations shown in controlled human publicity research to trigger respiratory results. In doing so, she centered on estimates of O3 exposures of concern at or above the benchmark concentrations of 60, 70, and 80 ppb. The Administrator judged that the proof supporting the occurrence of adverse respiratory effects is strongest for exposures at or above the 70 and 80 ppb benchmarks. Therefore, she placed a large amount of emphasis on the importance of setting a regular that limits exposures of concern at or above these benchmarks. As was the case for her consideration of the adequacy of the current major O3 commonplace (II.B.3, above), the Administrator positioned the best weight on the results of controlled human publicity research and on exposure and threat analyses based mostly on information from these research. In doing so, she noted that managed human exposure research provide the most sure evidence indicating the incidence of health results in humans following exposures to particular O3 concentrations. The effects reported in these studies are due solely to O3 exposures, and interpretation of research outcomes isn’t complicated by the presence of co-occurring pollutants or pollutant mixtures . the controlled human publicity studies of respiratory results” (Frey, 2014c, p. 5). In reaching a final decision on the type of the first O3 commonplace, as described in the proposal and above, the Administrator recognizes that there is not a transparent health-based mostly rationale for selecting a particular nth-highest every day most kind. Her foremost consideration is the adequacy of the general public health protection supplied by the mixture of the entire components of the usual, together with the form.
