## December 10 , 2013 Mr . Shawn M . Garvin Regional Administrator U.S. EPA Region III (3RAOO) 1650 Arch Street Philadelphia, PA 19103-2029 RE: West Virginia Preliminary Area Designations Under the 2012 PM 25 

## National Ambient Air Quality Standards Dear Administrator Garvin : EPA most recently revised the National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM 25 ) 

## on December 14,2012 and the related notice was subsequently published in the Federal R e gister on January 15,2013 [78 FR 3086] . Within one year of a new NAAQS promulgation, states are required to submit lists of all areas in their boundaries as attainment , nonattainment or un c lassijiable . West Virginia is attaching to this letter such a list, which provides a preliminary assessment of all areas within the State . Naturally , this list is subject to change as the fourth-quarter 2013 data is finalized and the s u cceeding annual values are quality assured and certified to complete the three year period 2011-2013 data required to calculate the final design value . As shown in Attachment 2 , the list was compiled by substituting the highest quarterly average PM 2 . 5 

## values observed from the previous three years, to derive surrogate 2013 fourth-quarter averages. This approach uses the available 2011

- 2013 monitoring data, supplemented by the substituted values. The methodology provides a conservative estimate (i . e. biased high) of the 2013 annual design value used in the three

- year overall design value, while also accounting for the decreasing trend observed in PM 2 5 

## concentrations statewide . We plan to send a formal design value update to EPA once the complete 2013 data is fully quality assured and certified. If y ou have any questions regarding this submittal or require additional information , please contact J ohn A. Benedict , Director of the Division of Air Quality at (304) 926-0462. Sincerely ,
