RE: Washington State Designation Recommendations for the 2012 National Ambient Air 

Quality Standard for Particulate Matter 

Dear Mr. McLerran: 

As the Governor's designee for the State Implementation Plan (SIP), I am submitting 

recommended designations for the new primary annual national ambient air quality standard 

(NAAQS) for fme particles (PM2.s). 

On December 14, 2012, EPA revised the primary annual PM2.5 NAAQS (78 FR 3086, January 

15, 2013). In that action, EPA strengthened the primary annual PM2.s NAAQS from 15.0 

micrograms per cubic meter (J.tg/m3

) to 12.0 J.lg/m

3

. EPA retained the following NAAQS: 

• Primary 24-hour PM2.s NAAQS at 35 J.lg/m3 

• Primary 24-hour PM10 (coarse particle ) NAAQS at 150 flg/m

3 

• Current suite of PM secondary NAAQS. 

The Clean Air Act provides each state with an opportunity to recommend designations of 

attainment (meets the NAAQS), nonattainment (does not meet the NAAQS), or unclassifiable 

(insufficient information) for all areas of the state. I recommend the designations listed in Table 

1 by county.

I have enclosed a spreadsheet with the monitoring data supporting these designation 

recommendations. I also enclosed a map created using "EPA's PM2.5 Designations Mapping 

Tool" that shows all of Washington's monitors have design values below 12.0 IJ.g/m

. 

Ecology met all state and federal procedural requirements. We published notice of the public 

comment period and opportunity to request a hearing on its website on September 13, 2013, 

which meets the requirement of 31 days advance notice. We did not hold a hearing because we 

did not receive a request for one. However, we did receive written comments. The enclosed 

Concise Explanatory Statement includes a compilation of public comments we received and our 

response to comments. 

If you have any questions, please contact Richelle Perez at (360) 407-7528 or
