Clean Air Act Promulgation of Extension of Attainment Date for PM-10 Nonattainment Area

Résumé

EPA proposes to grant a 1-year attainment date extension for the Denver, Colorado particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10) nonattainment area. This proposed action is based on monitored air quality data for the national ambient air quality standard for PM-10 during the years 1992-94 and EPA's evaluatation of the applicable state implementation plan (SIP). In the Final Rules Section of the Federal Register, EPA is granting the State's extension request, as a direct final rule without prior proposal because the Agency views this as a noncontroversial action and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this proposed rule, no further activity is contemplated in relation to this rule. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time.
