NOTICE OF AVAILABILITY
OF THE DEMONSTRATION OF THE OCCURRENCE
OF TWO EXCEPTIONAL EVENTS (EE) FOR
APRIL AND MAY 2015

The Imperial County Air Pollution Control District (Air District) has prepared two Draft Exceptional Event (EE) Demonstrations which support the requested exclusion of the measured concentrations at the Niland monitor on April 24 and May 7, 2015. (See below).

April 24, 2015
Niland 24 hr concentration from the Federal Equivalent Method BAM monitor of 168.2 ug/m3

May 7, 2015
Niland 24 hr concentration from the Federal Equivalent Method BAM monitor of 210.2 ug/m3

The public and all interested parties are encouraged to review and comment on the Draft EE's for April 24, 2015 and May 7, 2015 which provide the supporting evidence that on the days indicated in April and May of 2015 the Niland monitor was impacted by elevated levels of particulate matter of an aerodynamic size less than 10 microns (PM10) caused by winds which followed weather systems that impacted Riverside, Imperial and San Diego counties. The Draft EE Demonstrations provide the scientific justification for the requested exclusions. The Air District is soliciting and accepting comments for 30 days commencing the date of the publication of this notice. The final closing date for submitting comments is November 1, 2017 by close of business.

The Draft EE's for April and May of 2015 are available for download at the Air District website at www.co.imperial.ca.us, under "Air Pollution". To view a hard copy of the Draft EE demonstration, please visit the Air Pollution Control District office at 150 S. 9th Street, El Centro.
