        <RULE_TITLE>Revision to Pb Ambient Air Monitoring Requirements</RULE_TITLE>
        <ABSTRACT><![CDATA[On November 12, 2008, the Environmental Protection Agency (EPA) revised the National Ambient Air Quality Standards (NAAQS) for lead (Pb) and associated monitoring requirements. The finalized monitoring requirements require State and local monitoring agencies to conduct Pb monitoring near Pb sources emitting 1.0 tons per year (tpy) or more and in large urban areas referred to as Core Based Statistical Areas (CBSA) with a population of 500,000 people or more. In January 2009, EPA received a petition from the Missouri Coalition for the Environment Foundation, Natural Resources Defense Council, the Coalition to End Childhood Poisoning, and Physicians for Social Responsibility requesting EPA reconsider the 1.0 tpy emission threshold. EPA granted the petition to reconsider on July 22, 2009. This action represents the results of the EPAs reconsideration of the Pb monitoring requirements. 

A proposed revision was published on December 30, 2009, in which the EPA proposed to lower the emission threshold to 0.50 tpy, and to require Pb monitoring at the approximately 80 NCore sites instead of monitoring Pb in CBSA's with a population greater than 500,000. The EPA also requested comments on an emission threshold greater than 0.50 tpy, alternative approaches for monitoring Pb near airports, and on staggering the monitoring deployment over two years.]]></ABSTRACT>
