The U.S. Environmental Protection Agency (EPA) said it is proposing the steps state, local and tribal governments can take to reduce fine particle pollution (PM2.5) in areas that do not meet EPA’s health-based standards.
The proposed rule, known as the PM2.5 Implementation Rule, describes the planning framework and requirements for state, local and tribal governments to consider when developing their plan to reduce air pollution to meet the PM2.5 standards. Areas meeting the standard must show how they will ensure that PM2.5 levels remain below the standards. EPA issued the PM2.5 standards in 1997 and designated areas as attainment or non-attainment with the standard in December 2004. Non-attainment areas must meet the standards by 2010.
EPA will accept public comment on this proposal for 60 days from the date the notice appears in the Federal Register. For more information, visit: http://www.epa.gov/pmdesignations
