There are no PM10 Plans under development.
On September 25, 2008, EPA redesignated the San Joaquin Valley to attainment for the PM10
National Ambient Air Quality Standard (NAAQS) and approved the PM10 Maintenance Plan.
Emissions inventories developed by ARB for the District's 2007 PM10 Maintenance Plan and Request
for Redesignation are available
here.
These emissions inventories are a combination of data presented in Appendix A and Appendix F of the
District's Maintenance Plan. ARB's emissions inventories reflect reductions achieved by state measures
through the end of December 2006, whereas the Maintenance Plan inventories reflect reductions achieve
through May 2005 in Appendix A and subsequent reductions in Appendix F.

NEAP – Natural Events Action Plan
|
| NEAP Under
Development |
|
Back to top |
| The NEAP
was developed as a result of EPA approving a high
wind data flag for a PM10 exceedance in Corcoran
on September 3, 2004.
The NEAP
was approved by the District Governing Board on
February 16, 2006. The
purpose of the NEAP is to protect public health in
the event of future exceedances caused by natural
events. |

| A
requirement for data flagging and NEAP preparation
is for BACM to be in place. District
BACM is established in the PM10 Plans, so
regulations adopted to reduce PM10 contribute to
the NEAP. |

|
| The EPA Memorandum, “Areas Affected by PM10 Natural Events,” set forth the policy for data flagging and NEAP preparation. In March 2007, EPA posted its final rule, “Treatment of Data Influenced by Exceptional Events,” which includes policies for natural events as well as exceptional events.
