Timothy Twoguns, Representative CayugaNation P.O. Box 11 Versailles, NY 14168-0011 DearMr. Twoguns: I am writing you today to provide you with information on the process for designating areas that meet or may not meet the U.S. Environmental ProtectionAgency's (EPA) healthrelated National Ambient Air Quality Standards for lead. When EPA develops rules andpolicies we take ourresponsibility to consult with the federally recognized Indian tribes seriously and considerwhere these rules orpolicies may impact tribes and their environments. We want to make sure that we are effectively communicating with you to ensure early tribal input on the designations process for lead. On October 15, 2008, EPApromulgated amore stringent air quality standard for lead. This new standard is based on the mostrecent scientific studies and provides additional protection against adverse health effects associated with exposure to airborne lead. To provide increasedprotection against lead-related welfare effects, EPA also revised the welfare-related secondary standard to be identical in all respects to the more stringenthealth-related standard. When EPApromulgates anew orrevised NAAQS, we then designate all geographic areas within the United States as "attainment", "nonattainment", or "unclassifiable" under section 107 ofthe Clean Air Act (Act). Designating an area underthe Act is accomplished through a formal rulemaking process outlined in Section 107(d)(l) ofthe Act. Ifan area does not meet the national standard for the revised lead standard, or contributes to anearby areathat does not meet the standard, itwill be designated as nonattainment. EPA plans to announce its proposed designations as early as possible, but no laterthan 120 days priorto promulgating initial designations. As previously mentioned

- this 120 day period is established to allow states and tribes an opportunity to review and commentupon any changes EPA proposes to make on original recommendations. Under section 107(d)(I)(B) ofthe Act, EPA is requiredto issue final designations within two years ofpromulgation ofthe final National Ambient Air Quality Standard. However, EPA has the discretion to extend the deadline up to one year ifthere is insufficient information to make designations. EPA intends to complete initial designations by no laterthan October 15, 2010, where air quality data from the existing monitoring network is sufficient orwhere no additional data is expected to be available.

States and Indian tribes will have an opportunity to update their recommendations for these remaining areas by October 15,2010. Establishing area designations is a key step in the process ofproviding the health protection that the Act is intended to provide.
