Dear Chairman Rolin: ATLANTA FEDERAL CENTER 61 FORSYTH STREET ATLANTA, GEORGIA 30303-8960 

### FEB - 6 2013

I am writing today to inform you about the process for designating areas under the 2010 revision to the primaryNational Ambient Air Quality Standard for sulfur dioxide (S02 ). Reducing levels ofS02 pollution is an important part ofthe U.S. Environmental Protection Agency's commitment to a clean, healthy environment. Exposure to S02 can cause a range ofadverse health effects, including narrowing ofthe airways which can cause difficultybreathing and increased asthma symptoms. This letter is to notify you ofthe EPA's preliminary intentions regarding yourrecommended designations.
On June 3, 2010, the EPA strengthened the health-based or "primary'' standard for S02by establishing a standard for 1-hour average S02 concentrations at a level of75 parts perbillion. The Clean AirAct requires the EPA to complete the initial designations process within two years ofpromulgating a new or revised standard. Ifthe Administratorhas insufficient information to make these designations, the EPA has the authority to extend the designationprocess byup to one year. OnJuly 27, 2012, the EPA announced that it had insufficient information to complete the designations for the 1-hour so2 standard within two years and extended the designations deadline to June 3, 2013.
At this time, the EPA is proceeding with designating as nonattainment most areas in locations where existing monitoring data from 2009-2011 indicate violations ofthe 1-hour S02 standard. The EPA intends to address the designations for all other areas in separate future actions. With input from a diverse group ofstakeholders, the EPA has developed a comprehensive implementation strategy for these future actions that focuses resources on identifying and addressing unhealthy levels ofS02

. The strategy is available at: http://www.epa.gov/airquality/sulfurdioxide/implement.html. The EPA will continue to work closely with you and our otherpartners at the state, tribal and local levels to ensure health-protective, commonsense implementation ofthe 1-hour so2 standard.
The EPA'sreview ofthe most recent monitored air quality data from 2009-2011 shows no violations of the 2010**S~** standard in any ofthe Poarch Band ofCreek Indians trust lands. Consequently, the EPA is not yet prepared to propose designation action in the Poarch Band ofCreek Indians trust lands and is therefore currently deferring action to designate areas in the Poarch Band ofCreek Indians trust lands. The EPA expects to be able to proceed with designation action in the Poarch Band ofCreek Indians trust lands once additional data are gathered pursuant to ourcomprehensive implementation strategy. In a separate future action oractions the EPA will notify you ofourintended designations for these areas,
