How will we address the new federal standards for ozone and particulate matter?
In light of new public health data, the USEPA has issued new federal standards for ozone and particulate matter. The new federal ozone standard will be based on an 8-hour averaging time; it will replace the 1-hour ozone standard once it is attained. Attainment and nonattainment designations for the 8-hour ozone standard are expected by July 2000. The USEPA also established a new fine particulate standard (PM2.5) for both a short-term (24-hour) and long-term (annual) averaging period, as well as changing the form of the existing PM10 standard. Attainment and nonattainment designations for the new fine particulate standards are expected between 2002 and 2005. This Plan does not specifically address these new standards, although emission controls and inventories are analyzed and presented for the year 2005 for informational purposes. The USEPA is currently developing policies and guidance, as required under the federal Clean Air Act Amendments, for areas to follow as they plan to meet the
