EPA Makes Findings of Failure to Submit State Implementation Plans (SIPs) -- 1997 Fine Particle Pollution (PM2.5) Standard
October 3, 2008 - EPA issued findings that 21 states and territories missed Clean Air Act deadlines for submitting plans, or elements of plans, for implementing EPA’s 1997 national air quality standards for particle pollution. The notice also identifies 35 states who have submitted complete SIPs.

Clean Air Fine Particle Implementation Rule Will Help States Control Fine Particle Air Pollution
March 29, 2007 - EPA finalizes Clean Air Fine Particle Implementation Rule defining requirements for state plans to meet the 1997 national air quality standards for fine particle pollution.

EPA Completes Benefits and Costs Analysis of National Air Quality Standards for Particle Pollution
October 6, 2006 - EPA has completed its benefits and costs analysis of the national air quality standards for particle pollution, which EPA strengthened on Sept. 21, 2006. This regulatory impact analysis is designed to inform the public and states about the potential costs and benefits of implementing these important air quality standards. It is not a part of the standard selection process.

EPA Finalizes Amendments to its National Air Quality Monitoring Requirements
September 28, 2006 - EPA has finalized amendments to its national air quality monitoring requirements, including those for monitoring particle pollution.

EPA Strengthens National Ambient Air Quality Standards for Particle Pollution.
September 21, 2006 - Today the U.S. Environmental Protection Agency issued the strongest national air quality standards for particle pollution in our country’s history.

EPA's Provisional Assessment of Recent Studies on Health Effects of Particulate Matter Exposure Available
July 20, 2006 - In order to ensure that the EPA Administrator is fully aware of the new science before making a final decision on whether to revise or retain the current National Ambient Air Quality Standards for particulate matter, EPA conducted a survey and provisional assessment of relevant new studies. This final report is the result of that effort.

Direct Final Fine Particle Pollution De Minimis Emission Levels for General Conformity Applicability
March 31, 2006 - EPA established “de minimis” emission levels for fine particle pollution. These emissions thresholds will be used to determine whether requirements would apply under EPA’s General Conformity rules.

EPA Extends Public Comment on Implementing Proposed Particle Standards
March 29, 2006 - EPA is announcing a 90-day extension to the public comment period for its advanced notice of proposed rule making on how best to implement any new standards that may result from the recently proposed revisions to the particulate matter air quality standards. The public comment period will now end on July 10, 2006, rather than on April 10, 2006.

EPA Seeks Public Comment on Implementing Proposed Particle Standards
February 3, 2006 - EPA is seeking public comment on how best to implement any new standards that may result from the recently proposed revisions to the National Ambient Air Quality Standards for particulate matter (PM). This action will assure the public that EPA is aware of and is considering the multiple issues associated with implementing any revised or new particulate matter standards.

EPA Proposes to Revise the National Ambient Air Quality Standards for Particle Pollution
December 20, 2005 - The Environmental Protection Agency has proposed revisions to the National Ambient Air Quality Standards for particle pollution. The proposed revisions would strengthen a fine particle standard, and would improve and refocus the coarse particle standards on those particles that are associated with public health concerns. EPA will accept comments for 90 days after the publication of the proposal in the Federal Register.

EPA Proposes Amendments to its National Air Quality Monitoring Requirements
December 20, 2005 - In a separate but related action, EPA has proposed amendments to its national air quality monitoring requirements, including those for monitoring particle pollution. The proposed changes include the design of a network to monitor PM10-2.5. EPA will accept comments for 90 days after the publication of the proposal in the Federal Register.
