| 06-8478 | Revisions to Ambient Air Monitoring Regulations | Rule | The EPA is issuing final amendments to the ambient air monitoring requirements for criteria pollutants. The purpose of the amendments is to enhance ambient air quality monitoring to better serve current and future air quality management and research needs. The final amendments establish limited ambient air monitoring requirements for thoracic coarse particles in the size range of PM<INF>10-2.5</INF> to support continued research into these particles' distribution, sources, and health effects. The ambient air monitoring amendments also require each State to operate one to three monitoring stations that take an integrated, multipollutant approach to ambient air monitoring. In addition, the final amendments modify the general monitoring network design requirements for minimum numbers of ambient air monitors to focus on populated areas with air quality problems and to reduce significantly the requirements for criteria pollutant monitors that have measured ambient air concentrations well below the applicable National Ambient Air Quality Standards. These amendments also revise certain provisions regarding monitoring network descriptions and periodic assessments, quality assurance, and data certifications. A number of the amendments relate specifically to PM<INF>2.5</INF>, revising the requirements for reference and equivalent method determinations (including specifications and test procedures) for fine particle monitors. | 2006-10-17 | 2006 | 10 | https://www.federalregister.gov/documents/2006/10/17/06-8478/revisions-to-ambient-air-monitoring-regulations | https://www.govinfo.gov/content/pkg/FR-2006-10-17/pdf/06-8478.pdf | Environmental Protection Agency | 145 | The EPA is issuing final amendments to the ambient air monitoring requirements for criteria pollutants.
