| 2023-27874 | Approval of Implementation Plans for Air Quality Planning Purposes; State of Nevada; Clark County Second 10-Year Maintenance Plan for the 1997 8-Hour Ozone Standard | Proposed Rule | The Environmental Protection Agency (EPA) is proposing to approve, as a revision of the Nevada state implementation plan (SIP), the State's second 10-year plan for maintaining the 1997 8-hour ozone standard in Clark County ("Clark County Second Maintenance Plan" or "Plan"). The Clark County Second Maintenance Plan includes, among other elements, a base year emissions inventory, a maintenance demonstration, contingency provisions, and motor vehicle emissions budgets for use in transportation conformity determinations to ensure the continued maintenance of the 1997 National Ambient Air Quality Standards for ozone ("1997 ozone NAAQS" or "1997 8-hour ozone standard"). With this proposed rulemaking, the EPA is initiating the adequacy process for the 2017, 2023, and 2033 motor vehicle emissions budgets. The EPA is proposing these actions because the SIP revision meets the applicable statutory and regulatory requirements for such plans and motor vehicle emissions budgets. | 2023-12-21 | 2023 | 12 | https://www.federalregister.gov/documents/2023/12/21/2023-27874/approval-of-implementation-plans-for-air-quality-planning-purposes-state-of-nevada-clark-county | https://www.govinfo.gov/content/pkg/FR-2023-12-21/pdf/2023-27874.pdf | Environmental Protection Agency | 145 | The Environmental Protection Agency (EPA) is proposing to approve, as a revision of the Nevada state implementation plan (SIP), the State's second 10-year plan for maintaining the 1997 8-hour ozone standard in Clark County ("Clark County Second... |
