Comment on FR Doc # E7-05357

Docket No: EPA-R09-OAR-2007-0091-0001 According to the summary/justification offered by the EPA, the Phoenix area has been in nonattainment with 24 hour PM-10 standards since at least 1990, when the Clean Air Act Amendments were enacted. Since that time, Phoenix has managed to secured extensions through December 31, 2006. Upon further reading, it appears as though they have until December 31, 2007 to submit a revision plan which would provide for attainment. But if they don't make that date, they can have more time as to what is reasonably appropriate, up to 5 years. After the revision plan is submitted, Arizona may be able to obtain 10 additional years of extensions. These long extensions, while they do ensure that Arizona has the time needed to obtain an attainment for 24 hour PM-10, expose Arizona citizens to ongoing health risks associated with nonattainment of PM-10. It is very important that Arizona be in attainment with the EPA standard for PM-10 and for that reason, I request that sanctions (withholding of highway funds?) be instituted. If not, what is the point? Why have an Act which gives States pollution standards to compy with, if there is no method of enforcement available? At which point does the EPA stop granting extensions. At which point, does the EPA investigate whether the efforts made by a state to comply with EPA standards are made in good faith? Thank you, Concerned Arizona Citizen
