PROPOSAL:
Proposed National Ambient Air Quality Standards for Ozone
SYNOPSIS:
U.S. EPA is reconsidering the National Ambient Air Quality Standards (NAAQS) for ozone. U.S. EPA has proposed to lower the primary standard, which is designed to protect public health, from the current 0.075 ppm to a level within the range 0.060 to 0.070 ppm averaged over 8 hours. U.S. EPA also proposed a new form for the secondary standard, which is designed to protect public welfare (vegetation damage). Staff presented an overview of the proposed standards at the January 22, 2010 Mobile Source Committee meeting. The Committee requested that staff prepare draft comments to U.S. EPA on the proposed standards, and bring to the March Board meeting for discussion. This item is to seek Board direction on AQMD’s comments to U.S. EPA regarding the proposed ozone standards.
