Abstract
The purpose of this document is to provide areas that are nonattainment or maintenance for the annual PM2.5 national ambient air quality standard (standard) with guidance on developing annual PM2.5 on-road motor vehicle emissions estimates to meet state air quality implementation plan (SIP) and transportation conformity requirements. For previous and existing air quality standards (e.g., 1-hour ozone, 8-hour ozone, PM10 and carbon monoxide (CO)), areas typically have been required to examine a typical summer or winter day because areas were violating a standard established for a time period of 24 hours or less. As a result, these areas have developed on-road motor vehicle SIP inventories, motor vehicle emissions budgets (budgets), and regional emissions analyses1 for transportation conformity determinations using modeling inputs and parameters that were specific to a typical day within a particular season. However, all areas currently designated nonattainment for PM2.5 are violating the annual standard for this pollutant. In order to be consistent with this standard, these areas must develop annual emission inventories for the purpose of developing SIP budgets and demonstrating transportation conformity. This guidance provides information on how areas should fulfill these requirements.

Contents Notes
This guidance document describes how state and local agencies should prepare annual inventories for PM2.5 SIPs or regional conformity analyses. It provides a range of methods for producing those inventories and guidance on how to decide which method is most appropriate. For state and local agencies currently preparing a regional conformity analysis before a SIP is developed, this guidance provides the option of using a simpler inventory approach than what they might eventually use in the SIP. This document also addresses the possible use of the National Mobile Inventory Model (NMIM) in SIPs and conformity analyses.
