Dear Chairman Smith:

The purpose of this letter is to provide you with information concerning the U.S. Environmental

Protection Agency’s (EPA) designations process for the 2012 primary annual PM2.5national ambient air

quality standard (NAAQS). Your Tribe may find it important to engage with us in the process of

assigning designations for Indian country. Although your involvement is not required. we would like to

invite you to participate in the designations process and to offer you consultation. We want to ensure

transparent and effective communication in developing area designations for the revised PM2.5NAAQS.

On December 13. 2012, EPA revised the PM2.5NAAQS to increase protection of public health from fine

particle pollution. The annual PM2.5standard was strengthened from 15 ug/m 3to 12 ug/m 3.Establishing

initial area designations is a key step in the process of providing the health and/or welfare protection

intended by the Clean Air Act (CAA). Within two years of promulgation of a new or revised NAAQS,

EPA must list and designate all areas in the country as either:

Attainment - areas that meet the standard;

Nonattainment - areas that either do not meet the standard, or are contributing to a nearby area

that does not meet the standard; or

Unclassifiable - areas where there is insufficient information to make a determination as to

attainment.

These designations are based on current air quality information, recommendations from state governors

and tribal leaders, and other relevant information as discussed in the April 2013 designations guidance

Initial Area Designations j’ör the 20/2 Revised Primary Annual Fine Particle i’/ational Ambient Air

Quality Standard. The guidance is available on the EPA’s PM L)esignations website at

about developing tribal air quality designations is available in the September 2013 document Developing

Designation Recommendations jar Areas ofIndian Country, which is available here:

We are sending you this letter because we received a recommendation of attainment for your area. We

will keep you informed as we finalize designations for your Tribe’s area and invite and encourage you to

participate. Please notify us by June 13, 2014 if you are interested in consulting with us regarding a

recommended designation. When requested, consultation will be conducted in accordance with the EPA

roliev.htm

We plan to formally announce our intended designations for all areas by August 14, 2014. At that time

we will send another letter to you with our intended designation and offer an additional opportunity to

consult with us on any modifications EPA proposes make to your Tribe’s recommendation.

In accordance with section 107(d)(1)(B) of the CAA, we are required to issue final designations for the

PM2 5NAAQS no later than December 12, 2014. Our designations will be based on the most recent

three calendar years of certified, quality-assured monitoring data available, and any other relevant

information.

As the designation process moves forward, we will keep you informed of any additional guidance or

other support activities. We look forward to working with you to develop area designations under the

PM2.5NAAQS in a timely manner. If your Tribe is interested in consultation or has questions about the

designations process, please do not hesitate to contact me or Kerry Drake, Associate Director, Air

Division, of my staff, at 415-947-4157 or drake.kerrv(a’epa.o.
