PREVIOUS ACTION

The “ Redesignation Request and Maintenance Plan for the Truckee Meadows Carbon Monoxide Non

- Attainment Area ” was unanimously adopted by DBOH on September 22, 2005.

BACKGROUND

The EPA has established health

- based NAAQS for six criteria pollutants, including CO

. During the 1970 ’ s and 1980 ’ s, the Truckee Meadows portion of Washoe County frequently exceeded and violated the CO NAAQS. Because of these violations, the Truckee Meadows was designated as a

non

- atta inment area for the 8

- hour CO NAAQS. Non

- attainment areas, such as the Truckee Meadows, are required by the Clean Air Act (CAA) to develop a State Implementation Plan (SIP) demonstrating attainment of the NAAQS.

The Washoe County Health District

, Air Qu ality Management Division (AQMD) developed a SIP that identified and applied reduction strategies to the most significant wintertime CO categories in the Truckee Meadows. Th e main CO contributors included residential wood combustion and on

road motor vehi cle emissions

. The SIP resulted in air quality improvements

, and the Truckee Meadows attained the 8

- hour NAAQS in 199 5

.
In 2005, t he AQMD submitted a Redesignation Request and Maintenance Plan to the EPA demonstrat ing attainment and maintenance of the CO standards. EPA redesignated the Truckee Meadows to attainment of the CO NAAQS in 2008 . Since redesignation , monitored CO concentrations have been consistently more than 65% below the NAAQS. Although the current Main tenance Plan is effective through 2018, this Maintenance Plan is being prepared and submitted early in order to align transportation conformity analysis years with the PM 10 Maintenance Plan

. Transportation conformity analysis is required for long and shor t

- range transportation plans.

Th is Maintenance Plan was prepared in coordination with EPA, Regional Transportation Commission of Washoe County , Federal Highway Administration, Nevada Division of Environmental Protection, Nevada Department of Transportation, and Truckee Meadows Regional Planning Agency.

If the Second 10

- Year Maintenance Plan is adopted, it will be submitted to EPA through the Nevada Division of Environmental Protection as a revision to the Truckee Meadows portion of the Nevada CO SIP. To reduce printing resources and expenses, the Second 10

- Year Maintenance Plan is not included with this staff report. This document, including appendices, is 26 pages and can be accessed from the “ News & E vents ” section of the Air Qua lity Management Division website ( www.OurCleanAir.com )
