This application describes air quality monitoring results relative to the level of the National Ambient Air Quality Standards (NAAQS). Calculations have been performed in accordance with the individual NAAQS as described in 40 CFR Part 50. The information included in this application is intended for informational use only and does not constitute a regulatory determination as to whether an area has attained a NAAQS. The information has no regulatory effect. To have regulatory effect, a final EPA determination as to whether an area has attained a NAAQS or attained a NAAQS as of its applicable attainment date can be accomplished only after rulemaking that provides an opportunity for notice and comment. No such determination for regulatory purposes exists in the absence of such rulemaking.
