| E9-10677 | Approval and Promulgation of Air Quality Implementation Plans; Maryland; Attainment Demonstration for the Philadelphia-Wilmington-Atlantic City Moderate 8-Hour Ozone Nonattainment Area | Proposed Rule | EPA is proposing to disapprove the ozone attainment demonstration portion of a comprehensive State Implementation Plan (SIP) revision submitted by the State of Maryland to meet Clean Air Act (CAA) requirements for attaining the 8-hour ozone national ambient air quality standard (NAAQS) for Cecil County, which is the Maryland portion of the Philadelphia-Wilmington-Atlantic City moderate nonattainment area (Philadelphia Area). EPA is proposing to disapprove Maryland's attainment demonstration of the 8-hour ozone NAAQS for the Philadelphia Area because EPA has determined that the photochemical modeling does not demonstrate attainment, and the weight of evidence (WOE) analysis that Maryland uses to support the attainment demonstration does not provide the sufficient evidence that Cecil County will attain the NAAQS by the June 2010 deadline. | 2009-05-08 | 2009 | 5 | https://www.federalregister.gov/documents/2009/05/08/E9-10677/approval-and-promulgation-of-air-quality-implementation-plans-maryland-attainment-demonstration-for | https://www.govinfo.gov/content/pkg/FR-2009-05-08/pdf/E9-10677.pdf | Environmental Protection Agency | 145 | EPA is proposing to disapprove the ozone attainment demonstration portion of a comprehensive State Implementation Plan (SIP) revision submitted by the State of Maryland to meet Clean Air Act (CAA) requirements for attaining the 8-hour ozone national... |
