Area Designations for 1997 Ground-level Ozone Standards
Region 9: Recommendations and EPA Response
|
EPA originally asked the states and tribes to recommend whether or not areas
were in attainment in 2000. Many states and tribes complied, but because of continuing
litigation, the Agency deferred designation action. EPA asked the states and tribes to, by July 15, 2003, either reaffirm or revise their 2000 recommendations or submit new recommendations. EPA will make its final designations based upon these reaffirmed, revised, or new recommendations. State recommendations and EPA response letters are presented here. EPA will make final designations by April 15, 2004. Tribal information for both 2000 and 2003 is available on the Tribal Recommendations page. Correspondence from persons outside the agency is catalogued on the outside correspondence page. |
