| 2010-27635 | Determinations of Attainment by the Applicable Attainment Date for the Hayden, Nogales, Paul Spur/Douglas PM10 Nonattainment Areas, Arizona | Proposed Rule | EPA proposes to determine that the Hayden, Nogales, and Paul Spur/Douglas nonattainment areas in Arizona attained the National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter of less than or equal to a nominal ten micrometers (PM<INF>10</INF>) by the applicable attainment date of December 31, 1994. On the basis of this proposed determination, EPA concludes that these three "moderate" nonattainment areas are not subject to reclassification by operation of law to "serious." Lastly, on the basis of a review of more recent ambient monitoring data, EPA also is proposing to determine that the Hayden, Nogales and Paul Spur/Douglas nonattainment areas are not currently attaining the PM<INF>10</INF> standard. | 2010-11-02 | 2010 | 11 | https://www.federalregister.gov/documents/2010/11/02/2010-27635/determinations-of-attainment-by-the-applicable-attainment-date-for-the-hayden-nogales-paul | https://www.govinfo.gov/content/pkg/FR-2010-11-02/pdf/2010-27635.pdf | Environmental Protection Agency | 145 | EPA proposes to determine that the Hayden, Nogales, and Paul Spur/Douglas nonattainment areas in Arizona attained the National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter of less than or equal to a nominal... |
