| 2014-09458 | Data Requirements Rule for the 1-Hour Sulfur Dioxide (SO2) Primary National Ambient Air Quality Standard (NAAQS) | Proposed Rule | The Environmental Protection Agency (EPA) is proposing a rule directing state and tribal air agencies (air agencies) to provide data to characterize current air quality in areas with large sources of sulfur dioxide (SO<INF>2</INF>) emissions if such areas do not have sufficient air quality monitoring in place to identify maximum 1-hour SO<INF>2</INF> concentrations. The proposed rule describes criteria for identifying the sources around which air agencies would need to characterize SO<INF>2</INF> air quality. It also describes a process and timetables by which air agencies would characterize air quality around sources through ambient monitoring and/or air quality modeling techniques and submit such data to the EPA. The EPA has issued separate non-binding draft technical assistance documents on how air agencies can conduct such monitoring or modeling. The air quality data developed by the states in accordance with this rulemaking would be used by the EPA in future rounds of area designations for the 1-hour SO<INF>2</INF> National Ambient Air Quality Standards (NAAQS). | 2014-05-13 | 2014 | 5 | https://www.federalregister.gov/documents/2014/05/13/2014-09458/data-requirements-rule-for-the-1-hour-sulfur-dioxide-so2-primary-national-ambient-air-quality | https://www.govinfo.gov/content/pkg/FR-2014-05-13/pdf/2014-09458.pdf | Environmental Protection Agency | 145 | The Environmental Protection Agency (EPA) is proposing a rule directing state and tribal air agencies (air agencies) to provide data to characterize current air quality in areas with large sources of sulfur dioxide (SO<INF>2</INF>) emissions if such... |
