| E9-16795 | Public Hearings for Primary National Ambient Air Quality Standards for Nitrogen Dioxide | Proposed Rule | The EPA is announcing two public hearings to be held for the proposed rule "Primary National Ambient Air Quality Standards for Nitrogen Dioxide" which is published elsewhere in this Federal Register. The hearings will be held in Arlington, Virginia, on Monday, August 3, 2009 and Los Angeles, California, on Thursday, August 6, 2009. In the notice of proposed rulemaking, EPA proposes to make revisions to the primary nitrogen dioxide (NO<INF>2</INF>) national ambient air quality standard (NAAQS) in order to provide requisite protection of public health. Specifically, EPA proposes to supplement the current annual standard by establishing a new short-term NO<INF>2</INF> standard based on the 3-year average of the 99th percentile (or 4th highest) of the annual distribution of 1-hour daily maximum concentrations. The EPA proposes to set the level of this new standard within the range of 80 to 100 parts per billion (ppb) and solicits comment on standard levels as low as 65 ppb and as high as 150 ppb. Also, EPA proposes to establish requirements for an NO<INF>2</INF> monitoring network that will include monitors within 50 meters of major roadways. In addition, EPA is soliciting comment on an alternative approach to setting the standard and revising the monitoring network. Consistent with the terms of a consent decree, the Administrator will sign a notice of final rulemaking by January 22, 2010. | 2009-07-15 | 2009 | 7 | https://www.federalregister.gov/documents/2009/07/15/E9-16795/public-hearings-for-primary-national-ambient-air-quality-standards-for-nitrogen-dioxide | https://www.govinfo.gov/content/pkg/FR-2009-07-15/pdf/E9-16795.pdf | Environmental Protection Agency | 145 | The EPA is announcing two public hearings to be held for the proposed rule "Primary National Ambient Air Quality Standards for Nitrogen Dioxide" which is published elsewhere in this Federal Register.
