I. BACKGROUND

The federal Clean Air Act (Act) establishes planning requirements for those areas that exceed the

health-based National Ambient Air Quality Standards (standards). Areas are designated as

nonattainment based on monitored exceedances of these standards. These nonattainment areas must

develop an emission inventory as the basis of a State Implementation Plan (SIP) that demonstrates how

they will attain the standards by specified dates.

In 2008, the United States Environmental Protection Agency (U.S. EPA) strengthened the ambient air 

quality standard for 8-hour ozone from 0.08 to 0.075 parts per million (ppm). Effective July 20, 2012, 

U.S. EPA completed area designations for the 2008 8-hour ozone standard with sixteen areas in California 

classified as marginal, serious, severe, or extreme nonattainment (Figure 1). 

The Act requires states and local governments to prepare baseline emission inventories for all areas 

exceeding the National Ambient Air Quality Standards within two years of designation. The Emission

Inventory SIP Submittal has been compiled by Air Resources Board (ARB) staff and reflects the most up-todate emission inventory for all areas. Since the Statewide attainment challenges for the national 8-hour 

standard occur in the summer months, this document includes the 2012 baseline summer season (MayOctober) planning emission inventories (tons/day) for nitrogen oxides (NOx) and volatile organic 

compounds (VOCs), the two precursors to ozone formation, for the sixteen areas.

Emission inventory development is an ongoing process as new information becomes available and

methodologies and models are improved. Inventories are frequently updated for SIPs to improve accuracy 

and ensure they reflect the best available data. Further improvements are currently under way and will be 

incorporated into additional SIP revisions required for the new 8-hour ozone standard for areas with the 

worst air quality. This includes attainment SIPS in 2016. Ultimately, the inventories are evaluated and 

approved by U.S. EPA. 

The following areas in California have been designated as non-attainment:

1. Chico (Butte County)

2. Imperial County

3. Kern County (Eastern Kern)

4. Los Angeles-San Bernardino Counties (Western Mojave Desert)

5. Los Angeles-South Coast Air Basin

6. Mariposa County

7. Nevada County (Western Nevada)

8. Riverside County (Coachella Valley)

9. Sacramento Metropolitan Area

10. San Diego County

11. San Joaquin Valley

12. San Luis Obispo County (Eastern San Luis Obispo)

13. Ventura County

14. Calaveras County

15. San Francisco Bay Area

16. Tuscan Buttes*

*The Tuscan Buttes non-attainment area is a small high elevation area containing no anthropogenic 

sources and therefore, no emissions.

II. EMISSION INVENTORY BACKGROUND

An emission inventory is a systematic listing of air pollutant sources, along with an accounting of the

amount of pollutants emitted by each source or category over a given period of time. This accounting is an 

estimate of emissions, not a direct measurement of ambient concentrations. 

The emission inventory is an essential tool to support the evaluation, control, and mitigation of air 

pollutants. Inventory data are used as primary input for air quality modeling, for developing control 

strategies, and to provide a means to track progress in meeting emissions reduction commitments. More 

specifically, the inventories are used to assist in demonstrating attainment of the standards. 

California’s emission inventory represents emission estimates from many source types. Stationary 

sources include industrial point sources such as power plants and oil refineries. Area-wide sources 

include categories where emissions take place over a wide geographic area such as consumer 

products, cooking, and agricultural burning. Area-wide sources also include smaller point sources, 

such as gasoline dispensing facilities and residential water heaters, which are not inventoried 

individually but estimated as a group. On-road mobile sources include passenger vehicles and heavy-
5

duty trucks while off-road mobile sources include aircraft, trains, ships, and farm equipment. Natural 

(non-anthropogenic) sources include vegetation (biogenic), petroleum seeps and wildfires. Note that 

the emission inventories represented in this document include only anthropogenic sources.

The development and maintenance of California’s emission inventory is a multi-agency effort involving

ARB, 35 local air pollution control and air quality management districts, metropolitan planning

organizations, councils of governments, and the California Department of Transportation. Districts 

work with facility operators to provide stationary point source emission estimates. ARB and the districts 

use the best available methodologies to estimate emissions from both stationary and area-wide sources. 

ARB also develops and maintains mobile source emission models such as EMFAC. Metropolitan 

planning organizations also provide some population and transportation activity forecasts. These 

detailed stationary, area-wide, and mobile emission estimates, developed and provided by a variety of 

sources, are compiled and maintained by ARB in a comprehensive database.

A base year inventory contains the latest available data for a given calendar year and is used as a 

starting point for understanding current emission levels. Future-year inventories are developed by 

applying category-specific growth and control factors to the base year inventory to estimate projected 

emissions in future years. Growth and control factors represent the anticipated changes from the base 

year to the future years based on trends in economic and other human related activity as well as the 

effects of adopted emission control measures. Comparing base and future year inventories allows 

progress from emission reduction strategies to be measured. This submittal represents a base year 

inventory for 2012, chosen because it is the most recent year for which comprehensive emissions 

estimates are available.

III. UPDATES TO THE EMISSION INVENTORY 

The following improvements were made to the 2012 emission inventory since the last comprehensive 

update conducted for the 2012 24-hour PM2.5 SIPs:

Stationary Sources:

Emission estimates from stationary point sources are updated on an annual basis or as needed by the 

districts. Updates provided by districts for inventory year 2012 are included in this inventory.

Area-wide Sources:

The Bay Area Air Quality Management District updated the 2011 area source inventory which was 

projected to 2012 for all area source categories.

Pesticide emissions were updated to reflect actual emissions reported by the Department of Pesticide 

Regulation for the 2012 inventory year. ARB staff created a merged statewide VOC emission inventory for 

2012 from a mixed dataset which included emissions statewide and by ozone nonattainment areas.

On-Road Mobile:

On-road mobile emissions reflect recent draft updates to the EMFAC 2011 model. Updates to EMFAC 

include vehicle population and activity updates using Department of Motor Vehicles data, vehicle sales and 

survival rate estimates, fuel sales from Board of Equalization, and updates to mileage accrual rates using 

Smog Check data. Vehicle model year specific emission rates have been updated for medium-heavy and 

heavy-heavy duty diesel trucks. Rule compliance assumptions for the Truck and Bus regulation have also 
6

been updated. Lastly, the default vehicle miles traveled (VMT) regional allocations have been adjusted 

using the 2012 National Transportation Atlas Database. 

Off-road:

Off-road mobile emissions were updated with draft off-road data models. The following categories have 

been updated: ocean going vessels, recreational boats, recreational vehicles, off-road equipment and farm 

equipment.

The ocean going vessel inventory was updated to account for new information related to goods movement 

activity. The updates were based on growth projections from the Federal Highway Administrations Freight 

Analysis Framework model and supported by other forecasts done for the San Pedro Bay Ports.

Other off-road mobile categories such as cargo handling equipment, which use growth factors consistent 

with ocean going vessels, were also updated.

Off-road farm equipment emissions were updated as part of the in-use regulation development 

process. The updated inventory relies on newly available information from statewide surveys, economic 

assessments and a fuel analysis. The survey analysis resulted in an update to the age distribution of the

statewide fleet. The agricultural equipment inventory (principally tractors, but also including a wide variety 

of farm equipment such as harvesters, loaders, cotton pickers, etc.) was completely revised based on a 

2008 survey of California farmers, first processors, and equipment rental facilities. The detailed data on 

California farm practices was combined with statewide data on agricultural fuel use from the Board of 

Equalization, and United States Department of Agriculture data on farm equipment, to build a new inventory 

with revised equipment populations, activity, load factors, turnover practices and more.

IV. EMISSION INVENTORY – SPLIT REGIONS

Of the sixteen ozone non-attainment areas, five were split into regions not defined by ARB’s county, air 

basin, and district boundaries. These five regions include: Western Nevada County, Sutter County 

(Sacramento Metropolitan Area), Eastern Kern County, Los Angeles-San Bernardino (Western Mojave 

Desert) and Eastern San Luis Obispo County. For these areas, the portion of emissions in the 

nonattainment area was estimated using category-specific factors based on the spatial distribution of 

population, employment, VMT and other activity parameters within the non-attainment region. These 

fractions were developed by ARB and the local air districts. 

V. STAFF RECOMMENDATION

ARB staff has developed the 2012 emission inventory for ozone precursors in consultation with district staff 

and finds that the Emission Inventory SIP Submittal meets all applicable Clean Air Act requirements.

Therefore, staff recommends that the Board adopt the 8-Hour Ozone State Implementation Plan Emission 

Inventory Submittal and recommends that the Executive Officer transmit this submittal to U.S. EPA.
