Revisions to the California State Implementation Plan, South Coast Air Quality Management District
EPA is proposing to approve revisions to the South Coast Air Quality Management District portion of the California State Implementation Plan (SIP). These revisions concern particulate matter (PM) emissions from paved and unpaved roads and livestock operations and aggregate and related operations. We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
Oil Pollution Prevention; Spill Prevention, Control, and Countermeasure (SPCC) Rule-Compliance Date Amendment for Farms
EPA (or the Agency) is taking final action to amend the date by which farms must prepare or amend, and implement their Spill Prevention, Control, and Countermeasure Plans to May 10, 2013. The date is being amended because a large segment of the continental U.S. was affected by flooding during the spring and summer of 2011, and other areas were impacted by devastating fires and drought conditions. In addition, despite the targeted farm outreach efforts by EPA over the past ten months, the sheer number of farms throughout the U.S. makes it a challenge to reach those owners and operators of farms that may be subject to the SPCC Plan regulations. As a result, the Agency believes that farms need additional time to come into compliance with the requirements to prepare or amend and implement a SPCC Plan.
Air Quality Designations for the 2008 Lead (Pb) National Ambient Air Quality Standards
This rule establishes air quality designations for most areas in the United States for the 2008 lead (Pb) National Ambient Air Quality Standards (NAAQS). In a previous action established on November 16, 2010, the EPA designated as ``nonattainment'' 16 areas as violating the 2008 Pb NAAQS based on data from the pre-2010 monitoring network. For all other areas, the EPA deferred action so that data from newly deployed monitors could be considered in making appropriate designation decisions. In this action, the EPA is designating all remaining areas of the United States, including Indian country. The Clean Air Act (CAA) requires areas designated nonattainment by this rule to undertake certain planning and pollution control activities to attain the standards as quickly as reasonably possible.
