RE: West Virginia Preliminary Area

Designations Under the 2012 PM25

National Ambient Air Quality Standards

Dear Administrator Garvin:

EPA most recently revised the National Ambient Air Quality Standards (NAAQS) for fine particulate

matter (PM25) on December 14,2012 and the related notice was subsequently published in the Federal

Register 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 unclassijiable.

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

succeeding 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 PM2.5

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 PM25

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 you have any questions regarding this submittal or require additional information, please contact

John A. Benedict, Director of the Division of Air Quality at (304) 926-0462.

Sincerely,

\'~ .. ~
