In so doing, within the context of contemplating the adequacy of safety afforded by the present standard, the PA takes note of CASAC’s view regarding a 6% median RBL (Frey, 2014c, p. 12). Based on the summary of RBL vintage dog samoyed bath soap wash your paws poster estimates in the PA, the PA notes that the median species RBL estimate, across the eleven estimates

than 500 screens that may meet an alternate standard of 70 ppb in the course of the period are distributed across all 9 NOAA climatic areas and forty six of the 50 states . and the importance of the related impacts to public welfare. With regard to the commenter’s emphasis on recommendation from CASAC on the type of the secondary standard, the EPA agrees with the importance of giving such advice careful consideration. The EPA additional notes, nonetheless, that the Administrator is not legally precluded from departing from CASAC’s recommendations, when she has supplied an explanation of the reasons for such differences. Accordingly, in reaching conclusions on the revised secondary commonplace in this review, the Administrator has given cautious consideration to the CASAC advice on this evaluate and, when she has differed from CASAC vintage dog samoyed bath soap wash your paws poster recommendations, she has fully explained the reasons and judgments that led her to a different conclusion, as described in section IV.C.three below. the proportion of information with any visible foliar harm . As the evaluation is a cumulative analysis, every point graphed in the evaluation includes the records for a similar and lower W126 index values, so the analysis doesn’t evaluate results for teams of data with differing, non-overlapping W126 index values.
Rather, the points represent teams with data in widespread and the variety of information within the teams is larger for larger W126 index values (U.S. EPA, 2014b, part 7.2). Additionally, we observe that the pattern noticed within the cumulative evaluation is considerably influenced by the large number of data for which the W126 index estimates are at or below eleven ppm-hrs, more than two thirds of the dataset . With regard to consideration of results on crops, along with their comments concerning a median species RYL over 5% yield loss, famous above (Frey, 2014c, p. thirteen), the CASAC additional noted that “rop loss seems to be less sensitive than these other indicators, largely due to the CASAC judgment that a 5% yield loss represents an adverse impact, and in part as a result of more alternatives to change administration of annual crops” (Frey, 2014c, p. 14). will, accordingly, contribute to judgments made by the Administrator with regard to those results in reaching her final selections in this evaluate. the present O3 secondary standard are addressed on this part. Comments on specific issues or data that relate to consideration of the suitable components of a revised secondary commonplace are addressed beneath in part IV.C. Other particular feedback related to standard setting, as well as general feedback based on implementation-associated factors that are not a permissible basis for contemplating the need to revise the current standard, are addressed within the Response to Comments document. air pollution removing, and hydrologic and fire regime stabilization” (Frey, 2014c, p. 9). Similar to feedback from CASAC in the final review, and comments on the proposed reconsideration, the present CASAC additionally endorsed the PA discussions and conclusions on biologically relevant publicity metrics and the concentrate on the W126 index accumulated over a 12-hour interval (8 a.m.-8 p.m.) over the three-month summation period of a yr ensuing within the maximum worth (Frey, 2014c, p. iii). In contemplating the RBL estimates for various O3 conditions related to the current standard, the PA targeted primarily on the median of the species-particular E-R features.
