BACKGROUND

To protect the public health and welfare, federal and state standards limit concentration 

levels of air contaminants in ambient air, an emission inventory of air pollutants and 

their sources is essential to identify the major contributors of air contaminants and the

measures required to reduce air pollution. 2008 is the base year used to project future 

year emissions for the Final 2012 Air Quality Management Plan (AQMP). The 2008 

base year emissions inventory reflects adopted District air regulations that are 

implemented as of June, 2012 and CARB rules adopted by August 2011. Both the 

federal and state Clean Air Acts specify 1990 as the base year to measure emission 

reduction progress. In these inventories, only anthropogenic sources (i.e., those 

associated with human activity) are considered. 

This appendix includes six attachments: Attachment A – Average Annual Emissions 

Summary by Major Source Category; Attachment B – Summer Planning Emissions 

Summary by Major Source Category; Attachment C – Top South Coast Air Basin 

(SCAB) VOC and NOx producers which emitted equal to or greater than ten (10) tons 

per year in 2008; Attachment D – On-Road Emissions by Vehicle Category; Attachment 

E – Emissions from Diesel Fuel Combustion by Major Source Category; and Attachment 

F – 2008 Base Year Greenhouse Gas Emission Inventory Methodology and 2008 

Greenhouse Gas Emissions Summary by Major Source Category. The years of 2008, 

2014, 2017, 2019, 2023, and 2030 are provided in Attachments A, B, D and E, except 

year 2017 in Attachment D. Since Year 2017 transportation activity data is not provided 

by Southern California Association of Governments (SCAG), year 2017 on-road data is 

derived from the interpolation of the data between 2014 and 2019. 

Information necessary to produce the emission inventory for the Basin is obtained from 

the District and other governmental agencies, including California Air Resources Board 

(CARB), California Department of Transportation (Caltrans), and SCAG. Each of these 

agencies is responsible for collecting data (e.g., industry growth factors, socio-economic 

projections, travel activity levels, emission factors, emission speciation profile, and 

emissions) and developing methodologies (e.g., model and demographic forecast 

improvements) required to generate a comprehensive emissions inventory. Entire 

statewide emissions inventories are compiled and maintained by CARB in its emission 

related information databases named California Emission Inventory Development and 

Reporting System (CEIDARS), and California Emission Forecasting and Planning 

Inventory System (CEFIS). CARB is the agency responsible for developing the 

emissions inventory for all the mobile sources, except the aircraft. CARB provided on-

road and most of the off-road inventories using its EMFAC 2011 and 2011 In-Use Fleet 

Off-Road Models. Caltrans provides SCAG with information regarding highway 

projects. SCAG incorporates these data into their Travel Demand Model for 

estimating/projecting vehicle miles traveled (VMT) and speeds. SCAG‟s socioeconomic and transportation activities projections in their 2012 Regional Transportation 

Plan (RTP) are applied in the Final 2012 AQMP. On-road emissions are derived from 

the emission factors in CARB‟s EMFAC2011 and transportation activities and speed 

distribution from SCAG‟s Travel Demand Model.

AIR CONTAMINANTS

Currently, air quality standards exist for the following criteria air contaminants: ozone 

(O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), fine 

suspended particulate less than 10 microns (PM10), fine particulate less than 2.5 microns 

(PM2.5), lead, and sulfate. This appendix presents emission levels in the Basin for the 

criteria air contaminants and their precursors. Specifically, data are included for 

emissions of total organic gases (TOG), volatile organic compounds (VOC), oxides of 

nitrogen (NOx), oxides of sulfur (SOx), CO, particulate matter (PM), PM10, PM2.5, and 

ammonia (NH3). 

Ozone is formed from photochemical reactions involving other air contaminants so it is 

not inventoried. Although air quality standards for NOx and SOx are based on NO2 and 

SO2, respectively, emissions of NOx and SOx are in the emissions inventory because 

multiple species of NOx and SOx contribute to the formation of particulate, and NOx 

and VOC react in the presence of sunlight to produce ozone. 

TOG incorporates all gaseous compounds containing the element carbon with the 

exception of the inorganic compounds, CO, carbon dioxide (CO2), carbonic acid, 

carbonates, and metallic carbides. VOC, a subset of TOG, includes all organic gases in 

TOG except acetone, ethane, methane, methylene chloride, methylchloroform, 

perchloroethylene, methyl acetate, parachlorobenzotrifluoride, and a number of Freontype gases. It should be noted that this definition of VOC is different from the one used 

by the CARB, which includes some compounds not considered as VOCs according to 

U.S. EPA. Table III-1-1 lists the compounds that are exempt in U.S. EPA‟s VOC list, 

but are included in CARB‟s VOC list. Certain CFCs are still included in CARB‟s VOC 

list. According to CARB, the total emission inventory difference between U.S. EPA 

VOC and CARB‟s VOC is very small. 
Chapter 1: Inventory Development

III-1-3

PM represents all airborne particulate matter. Important subsets of PM are PM10 and 

PM2.5. In the Final 2012 AQMP, the amount of VOC in TOG and the amount of PM10 

and PM2.5 in PM are calculated for each process primarily using species and size 

fraction profiles provided by CARB. Besides average annual day emissions that are 

reported for all criteria pollutants, summer planning inventories (VOC and NOx) are 

reported for ozone purposes.

INVENTORY SOURCE CATEGORIES

Stationary Sources

Stationary sources of emissions are grouped into two categories - point sources and area 

sources. Point source emissions are from facilities having one or more pieces of 

equipment registered and permitted with the District. Therefore, the District is able to 

collect facility emission-related information from the larger of these facilities. Area 

source emissions are from numerous small facilities or pieces of equipment, such as 

gasoline-dispensing facilities, residential water heaters, consumer products and 

architectural coatings, for which locations may not be specifically identified. For 

modeling purposes, area source emissions are spatially allocated to grid cells using 

demographic data (e.g., population, housing, and land use).

Point Sources

The 2008 point source emission inventory is based on the emissions data reported by 

point source facilities in the calendar year 2008 Annual Emissions Reporting (AER) 

Program. This program applies to facilities emitting 4 tons or more of VOC, NOx, SOx, 

or PM or emitting more than 100 tons of CO per year, as specified in Rule 301(e). 

Facilities subject to the AER Program calculate and report their emissions primarily 

based on their throughput data (e.g., fuel usage, material usage), appropriate emission 

factors or source tests, and control efficiency (if applicable). Under the calendar year

2008 AER Program, approximately, 1,800 facilities reported their annual emissions to 

the District. Emissions from smaller industrial facilities not subject to the AER 

program, which represent a small fraction of the overall inventory, are included as part 

of the area source inventory. 

In order to prepare the point source inventory, emissions data for each facility were 

categorized based on U.S. EPA‟s Source Classification Codes (SCCs) for each emission 

source category. Since the AER program collects emissions data on an aggregate basis 

(i.e., equipment and processes with same emission factor are grouped and reported 

together), facility‟s equipment permit data were used in conjunction with the reported 

data to assign the appropriate SCC codes and develop the inventory at the SCC level. 

For modeling purposes, facility location is specified in Universal Transverse Mercator 

(UTM) coordinates. Business operation activity profile is also recorded. Facility 

business type is assigned to the facilities based on North American Industry 

Classification System (NAICS) Code according to their primary activity. The growth 

projections and impact of the AQMP on the local economy are presented by NAICS.
Chapter 1: Inventory Development

III-1-5

Area Sources

The District and CARB shared the responsibility for developing the 2008 area source 

emissions inventory for approximately 400 area source categories. Specifically, the 

District developed the area source inventory for about 150 categories whereas CARB 

developed the remaining area source categories (such as consumer products, and 

degreasing). For each area source category, a specific methodology is used for 

estimating emissions. In the 2008 area source inventory, a number of existing 

methodologies were used with updated activity data such as fuel data or sales data (e.g., 

fuel combustion categories, oil/gas production). Five new categories (i.e., LPG 

transmission, Storage and pipeline cleaning, three architectural coating colorants) were 

added to the inventory, other existing methodologies were refined based on more recent 

studies (e.g., landfills, composting waste, consumer products, architectural coatings), 

and some of the area sources were expanded (i.e., Commercial/Industrial internal 

combustion to include portable equipment engines).

Changes in Point Sources 

The point source inventory continued its downward trend primarily due to the 

implementation of existing stationary source regulations. As indicated in Figure 1-1, the 

point sources decreased between 2002 and 2008 in VOC, NOx and SOx emissions. The 

decreases are from 52, 41, and 20 tons per day to 34, 34 and 13 tons per day for VOC, 

NOx and SOx respectively. In addition to the effect of existing regulations, another 

reason for the decreases is due to the recessionary impacts. 

Changes in Area Sources 

The area source inventory also decreased between 2002 and 2008 for all criteria 

pollutants, except NOx. Figure 1-2 shows VOC, NOx, SOx and PM2.5 changed from 

265, 48, 2, 51 tons per day to 231, 53, 1 and 39 tons per day between 2002 and 2008. 

The reason for NOx increase is because the expansion of fuel consumption to include 

commercial and industrial portable equipment emissions.

Rule Implementation 

A list of the District‟s VOC, NOx, PM2.5 and SOx emission reduction commitment by 

measure/adopted date by pollutant since 2007 State Implementation Plan (SIP) is 

presented in Table III-1-2. Table III-1-3 lists SCAB NOx, VOC, PM2.5, and SOx

emission progress since 2007 SIP to date on CARB rules for year of 2014 and year 

2023.

Improved/Updated Methodologies

Fuel Combustion Sources - The emissions from commercial and industrial internal 

combustion engines were updated to include portable equipment emissions which were 

overlooked in the 2007 AQMP. The update causes increases in emissions for this 

category.

Landfills - The emission estimation methodology for this area source category was 

revised to incorporate the CARB‟s landfill GHG emission inventory data to calculate the 

amount of Methane (CH4) being generated in 2008. The TOG and VOC emissions were 

estimated using the emission factors from the “1982 Task Force Report”, which were the 

same factors used to estimate TOG/VOC emissions for this source category in the 2007 

AQMP. The baseline emissions from this source category in 2012 AQMP had 

drastically increased as compared with 2002 baseline used in 2007 AQMP. This was 

due to erroneous activity data reported by the point sources in 2002.

Metal Coating Operations - This area source category in the 2007 AQMP included the 

emissions from the small permitted facilities with VOC emissions below 4 tons per year. 

However, emissions from such smaller permitted facilities maybe underrepresented in 

the 2007 AQMP. During the amendment development process for Rule 1107, staff 

discovered numerous small shops using coating materials with compliant high solid 

concentrations, which are subsequently thinned beyond the allowable limit permitted by 

Rule 1107. The revised inventory adjusts the 2007 AQMP inventory to account for 

excess emissions from these coating activities as well.

LPG Transmission - This is a new area source category created to include the fugitive 

emissions associated with transfer and dispensing of LPG and is based on emission rates 

derived from SCAQMD source tests conducted in 2008 and 2011 and on sale volumes 

provided by the industry association and category breakdowns.

Storage Tanks and Pipeline Cleaning - A new area source category was added to 

include the emissions from the degassing of storage tanks and pipelines. As part of Rule 

1149 amendment, the previous inventory for this category was updated to reflect more 

frequent degassing events as well as effectiveness of control techniques. It was 

determined that the actual degassing events were more than triple the amount estimated 

when the rule was originally developed. It was also assumed that once degassing rule 

requirements were fulfilled, there were no more fugitive emissions; however, a review of 

degassing logs indicated that sludge and product residual in the storage tanks 

significantly increase the emissions emanating from the storage tanks. Finally, the 

source category was expanded to include previously exempted tanks and pipelines.
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventory

III-1-12

Livestock Waste - The inventory for this category was updated to reflect the split of 

dairy cattle into milking cows, dry cows, calves, and heifers fractions since each has a 

different VOC emission factor as a function of their manure production.

Gasoline Dispensing - For this source category, the 2008 baseline emissions are the 

projected values as estimated in 2007 AQMP. However, in the 2007 AQMP, the 

emissions from gasoline dispensing were adjusted to account for 75% compliance levels 

identified in various audits conducted by the District since 1997. Based on the recent 

tests conducted at retail gas dispensing facilities on their In-Station Diagnostic (ISD) 

System, about 18% of the facilities demonstrated non-compliance (i.e., failed the test). 

As such, to account for this nonconformance with the requirements, the 75% compliance 

rate was carried over to 2012 AQMP. 

Consumer Products - This category was updated to reflect the three most recent 

surveys conducted by CARB‟s Stationary Source Division (SSD) for the years 2003, 

2006, and 2008. Together these surveys collected updated product information and 

ingredient information for approximately 350 product categories. Based on the survey 

data, CARB staff determined the total product sales and total VOC emissions for the 

various product categories. Before the emissions inventory was updated, some of the 

existing categories were split out into more specific categories, others were combined, 

and new categories were added to better reflect changes in formulations of existing 

products. The updated survey data reflect VOC reductions from several rulemaking with 

the net result being an overall emissions decrease. The updates conclude that the 

projected 2008 emissions in the 2007 AQMP are the same as the 2008 emissions in the 

Final 2012 AQMP (98 tons per day).

Architectural Coatings - Three new area source categories were added under this 

category to accurately track the emissions from the colorants. VOC emissions from 

colorants, pigments added at the point of sale that impart the selected color, had 

specifically been excluded from Rule 1113, both in terms of the baseline emissions and 

any VOC restrictions. During the June 3, 2011 Rule 1113 amendment, VOC limits were 

included in the Rule. The emissions for architectural coatings were also updated to 

include the 2008 sales and emissions data that the manufacturers submitted under Rule 

314 – Fees for Architectural Coatings. Rule 314 requires manufacturers to annually 

report the quantity and emissions of their architectural coatings sold into or within the 

District‟s jurisdiction. This data provides more accurate and updated emission estimates.

Composting - The emission estimation methodology for this area source category was 

revised to include the emissions from green waste composting covered under District 
Chapter 1: Inventory Development

III-1-13

Rule 1133.3. The 2007 AQMP only included the emissions from co-composting, as it 

relates to the District Rule 1133.2. 

Biogenic Volatile Organic Compounds - Emissions of biogenic volatile organic 

compounds (BVOCs) were updated to reflect the day specific temperature, relative 

humidity, and solar radiation inputs used in the ozone and PM2.5 air quality modeling. 

BVOC emissions were modeled for everyday in 2008. The 2008 BVOC inventory was 

developed by CARB. 

Fugitive Dust - Subsequent to the approval of the 2003 AQMP, CARB released updated 

emission factors for several fugitive dust sources. The Final 2007 AQMP incorporated 

those updated emission factors and/or 2002 activity data for source categories such as 

entrained paved and unpaved road dust, construction, windblown dust, and farming 

operations. One of the more significant changes was that the factors used to quantify the 

PM2.5 fraction of PM10 were updated based on studies by the Dust Emissions Joint 

Forum of the Western Regional Air Partnership (WRAP). These fractions represented 

the latest technical information for deriving the PM fine fraction (PM2.5-10) of crustal 

fugitive dust from various sources, including paved and unpaved roads, agriculture, 

aggregate handling and storage piles, construction/demolition, and wind erosion. The 

fractions are currently in AP-42 guidance for fugitive dust sources (U.S. EPA, 

November 2006). As noted in the 2007 AQMP, the unspecified category emissions 

inventories were develop to reflect emissions from private paved and unpaved roads, and 

emissions from aggregate processing and storage based on facilities subject to Rule 1156 

(cement manufacturing) and Rule 1157 (aggregate and related operations). The 2008 

baseline inventory for the 2012 AQMP also includes these updates. In addition, the 

paved road emissions inventory methodology was modified using the latest AP-42 

method for quantifying emissions from paved roads (January 2011). In conjunction with 

CARB, in using this latest paved road methodology, California-specific PM2.5/PM10 

fraction (15%) and silt loading variables were used in lieu of the AP-42 default factors. 

Overall emission estimates were lower for the 2012 AQMP. Table III-1-4 indicates the 

changes in PM2.5 (tons per day) to the fugitive dust inventories. The updated paved 

road emissions methodology resulted in a significant reduction in emissions, as did the 

lower construction emissions which are a result of depressed economy.

Special Studies

Aircraft – The aircraft emissions inventory is updated for the 2008 base year and the

2035 forecast year based on the latest available activity data and calculation 

methodologies. A total of 43 airports were identified as having aircraft operations within 

the District boundaries including commercial air carrier, air taxi, general aviation, and 

military aircraft operations. The sources of activity data included airport operators (for 

several commercial and military airports), Federal Aviation Administration‟s (FAA)

databases (i.e., Bureau of Transportation Statistics, Air Traffic Activity Data System, 

Terminal Area Forecast), and SCAG‟s projections. For commercial air carrier 

operations, SCAG‟s 2035 forecast, which is consistent with the forecast adopted for the 

2012 Regional Transportation Plan (RTP), was used reflecting the future aircraft fleet 

mix. The emissions calculation methodology was primarily based on the application of 

FAA‟s Emissions and Dispersion Modeling System (EDMS) model for airports with 

detailed activity data for commercial air carrier operations (by aircraft make and model). 

For other airports and aircraft types (i.e., general aviation, air taxi, military), the total 

number of landing and takeoff activity data was used in conjunction with the U.S. EPA‟s 

average emission factors by major aircraft type (e.g., general aviation, air taxi, military). 

For the intermediate milestone years, the emissions inventories were linearly 

interpolated between 2008 and 2035.

Ammonia Sources –New 2008 ammonia emissions inventory has been developed for 

the Final 2012 AQMP development. In conjunction with the ongoing efforts by CARB 

to develop a state-wide inventory, the District and CARB staffs have worked extensively 

to develop a new and comprehensive 2008 ammonia inventory for all ammonia source 

categories. All source categories were reviewed and updated for emission factors, 
Chapter 1: Inventory Development

III-1-15

activity data, and spatial and temporal surrogates. Two new source categories of wood 

combustion and off-road mobile sources were added to the 2008 inventory. There has 

been a change in major ammonia emission sources. In 2002 inventory, major sources 

were on-road mobile (30%), livestock (22%), and domestic (21%) sources while 

domestic (23%), on-road mobile (20%), industrial (19%), composting (17%) and 

livestock (14%) sources are major ammonia sources in new 2008 inventory. 2008 Basin 

total ammonia emissions is 107 tons per day that is 12 tons per day less than 2002 Basin 

total ammonia emissions of 119 tons per day. 2008 Basin ammonia emissions from 

livestock, fertilizer application and on-road mobile emissions are decreased from 2002 

emissions while soil, landfill, industrial, and composting emissions are increased from 

2002 emissions. This updated ammonia emissions inventory has been used for PM 

modeling for the Final 2012 AQMP development. Table III-1-5 summarizes the changes 

to the ammonia inventory.

Mobile Sources

On-Road Mobile Sources

The Final 2012 AQMP emission estimates for on-road motor vehicles come from 

applying the emission rates in CARB‟s EMFAC2011 model to the transportation activity 

data provided by Southern California Association of Government (SCAG) in its adopted 

2012 Regional Transportation Plan (RTP). The California Department of Transportation 

(Caltrans), the Department of Motor Vehicles (DMV), and SCAG supply CARB with 

data necessary to develop the on-road mobile source emissions inventory. DMV 

maintains a count of registered vehicles and Caltrans provides highway network, traffic 

counts and road capacity data. SCAG maintains the regional transportation model 

containing the temporal and spatial distribution of motor vehicle activity (travel time, 

travel speed, and volume of traffic for AM-peak, mid-day, PM-peak, evening and night 

hours). In addition, SCAG periodically conducts origin and destination surveys to 

validate the regional transportation model. SCAG also updates a demographic database 

for population, housing, employment and patterns of land use within the District‟s

jurisdiction.

Emission rate data in the EMFAC2011 are collected from various sources, such as 

individual vehicles in a laboratory setting, tunnel studies and certification data, etc. 

Vehicle activity data are obtained from regional planning agencies, such as SCAG. The 

EMFAC2011 model calculates exhaust and evaporative emission rates by vehicle type 

for different vehicle speeds and environmental conditions (temperature and relative 

humidity). Temperature and humidity profiles are used to produce month specific, 

annual average, and episodic inventories. 

Parameters accounted for by the EMFAC2011 include the following: type of emissions 

control technology, fuel type, distribution of operating speeds, speed and temperature 

correction factors, and the reduction in emissions resulting from the state‟s motor vehicle 

regulatory programs. 

The EMFAC2011 includes the following mobile source breakdowns: 

(1) eight vehicle classes (light-duty passenger; light-duty trucks under 3,750 pounds;

light- duty trucks between 3,750 pounds and 5,750 pounds; medium-duty trucks

between 5,751 pounds and 8,500 pounds; light-heavy-duty trucks between 8,501 

pounds and 10,000 pounds; light-heavy-duty trucks between 10,001 pounds and 

14,000 pounds; medium heavy duty trucks between 14,001 pounds and 33,000 

pounds ; and heavy-heavy-duty-trucks for over 33,000 pounds);
Chapter 1: Inventory Development

III-1-17

(2) two vehicle fuel types (gas and diesel); 

(3) truck types (ports, agriculture, construction, interstate, out-of-state, public fleet,

utility fleet, power take off, tractor); 

(4) in-state and out-of-state;

(5) forty-five calendar years (1990-2035); 

(6) two vehicle exhaust processes (starts and running); 

(7) four evaporative processes (diurnal, hot soak, running loss, and resting loss); 

(8) seven pollutants (HC, CO, CO2, NOx, PM, SOx, lead); and 

(9) fuel consumption. 

To develop the detailed emission inputs needed by air quality dispersion models such as 

the Community Multi-scale Air Quality model (CMAQ) and Comprehensive Air Quality 

Model with eXtentions (CAMx), emissions from on-road motor vehicles are estimated at 

the grid level using Caltrans‟ Direct Travel Impact Model (DTIM). DTIM calculates 

emissions based on detailed information regarding each link (roadway segment) in an 

area for each hour of the day. The required inputs of DTIM include traffic volume, 

traffic speed, vehicle fleet characteristics, ambient temperature, and emission factors of 

vehicle fleets. 

It should be noted that even though the EMFAC2011 is expanded to include more subvehicle class categories for some of the major vehicle class categories (i.e., mediumheavy duty diesel trucks & heavy-heavy diesel trucks) based on their weights (heavy or 

small), types (agricultural, construction, CA international registration plan), by road 

types (in-state or out-of-state), etc, the on-road mobile sources emissions in the Final 

2012 AQMP are reported by major vehicle class categories to compare with previous 

inventory reporting. 

The characteristics of DTIM include: 

(1) emissions calculations based on specific information, such as link speed, link 

volume, and temperature; 

(2) spatial and temporal distribution of emissions to provide hourly gridded 

emissions; and, 
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventory

III-1-18

(3) emission impacts of various types of transportation and regional planning 

alternatives (e.g., changes in roadway network configuration, or public transportation 

services). 

DTIM reformats and sorts emission rates for all vehicle classes produced by the 

EMFAC2011. It then produces average emission rates for specific vehicle classes 

identified by the user. Finally, it produces regional mobile source emissions and hourly 

gridded mobile emissions. DTIM does this by combining emission rates with vehicle 

activity estimates derived from a transportation demand model and supplemental 

information on temperatures and temporal patterns. 

The EMFAC2011 was the basis for on-road planning inventories, emission budgets, and 

rate-of-progress calculations. EMFAC2011 has been updated to:

 Include the impacts of recently adopted diesel regulations including the Truck 

and Bus Rule and other diesel truck fleet rules: the Pavley Clean Car Standard, 

and the Low Carbon Fuel Standard.

 Reflect the latest emissions inventory methods for heavy duty trucks and buses, 

and the impact of the economic recession.

A detailed description of the EMFAC2011 changes is available at CARB‟s website 

(http://www.arb.ca.gov/msei/msei.htm). 

Several additional external adjustments are made to EMFAC2011 to reflect CARB‟s 

rules and regulations which were adopted after the development of EMFAC2011. The 

adjustments include the advanced clean cars regulations adopted in January 2012, 

reformulated gasoline, and Smog Check improvements. Figure 1-3 compares the 2008 

and 2023 on-road baseline emissions between EMFAC2007 V2.3 and EMFAC2012 

used in the 2007 AQMP and Final 2012 AQMP, respectively. It should be noted that 

the comparison for 2008 reflects changes in methodology, but the comparison for 2023 

also includes adopted rules and updated growth projections since the release of 

EMFAC2007. In general, the emissions are lower in EMFAC2011 than in 

EMFAC2007. The lower emissions can be attributed to additional rules and regulations 

which reduce emissions, future growth corrections, and recessionary impacts.

Off-Road Mobile Sources

Mobile sources not included in the on-road mobile source emissions inventory are 

considered as off-road mobile sources. CARB uses a number of models to estimate 

emissions for more than one hundred off-road equipment types. The models account for 

the effects of various adopted regulations, technology types, and seasonal conditions on 

emissions. The models combine population, equipment activity, horsepower, load 

factors, population growth, retirement factors, and emission factors to yield the annual 

emission by county, air basin or statewide. Temporal usage profiles are used to develop 

seasonal emission estimates which are then spatially allocated to the county or air basin 

using surrogates such as population.

The emission inventories were developed using CARB‟s 2011 In-Use Off-Road Fleet 

Inventory model for the Final 2012 AQMP. The 2011 In-Use-Off-Road Fleet Inventory 

model was last updated in 2011 and most data was obtained several years before. It 

reflects CARB‟s rules and regulations adopted since the 2007 AQMP. The description of 

these models is presented as follows:

 2011 In-Use Off-Road Fleet Inventory Model - This is an Access database model 

that forecasts future vehicle population data by type, model year, and horsepower 

from the Off-Road Simulation Model (OSM). The Model was developed in 2010 to 

support the analysis for amendments to the In-Use Off-Road Diesel Fueled Fleets 

Regulation. The equipment population in CARB‟s In-Use Off-Road Fleet Inventory 

Model is updated using the equipment population reported to CARB for rule 

compliance. According to CARB, the total population in 2009 was 26% lower than 

had been anticipated in 2007 due to fleet downsizing during the recent recession. The 

equipment hours of use in the Model are updated based on the reported activity data 

between 2007 and 2009. According to CARB, the new data indicated in most cases 

30% or greater reduced activity in 2009 compared to 2007 as a result of the recession. 

The equipment load factor in CARB‟s In-Use Off-Road Fleet Inventory model is 

updated using a 2009 academic study and information from engine manufacturers. 

According to CARB, the new data suggest the load factors should be reduced by 33%. 

The model calculates NOx, PM, and VOC, CO2 and SOx emissions. The models can 

be downloaded from CARB‟s website at 

http://www.arb.ca.gov/msei/categories.htm#offroad_motor_vehicles

 Cargo Handling Emission Inventory Model - This is an Access database model for 

diesel equipment subject to regulation for Mobile Cargo Handling Equipment at Ports 

and Intermodal Rail Yards. Cargo handling equipment has been updated for 
Chapter 1: Inventory Development

III-1-21

population, activity, recessionary impacts on growth, and engine load. The updates 

are based on new information collected since 2005. The new information includes 

CARB‟s regulatory reporting data which provides an accounting of all the cargo 

handling equipment in the state including their model year, horsepower and activity. 

In addition, the Ports of Los Angeles and Long Beach have developed annual 

emissions inventories and a number of the major rail yards and other ports in the state 

have completed individual emission inventories. The model can be downloaded from 

CARB‟s website at 

http://www.arb.ca.gov/msei/categories.htm#offroad_motor_vehicles

 Transportation Refrigeration Unit (TRU) Model – This is an Access database 

model for diesel engines subject to Airborne Toxic Control Measure for In-Use 

Diesel-Fueled Transport Refrigeration Units (TRU) and TRU Generator Sets and 

Facilities Where TRUs Operate (TRU Rule). The TRU model was developed to 

support analysis for the 2011 amendments to the TRU Rule. The current inventory is 

based on updated activity, population, growth and turn-over data, and updated 

emission factors and takes into consideration the requirements of the TRU Rule. The 

model can be downloaded from CARB‟s website at 

http://www.arb.ca.gov/msei/categories.htm#offroad_motor_vehicles

 Ocean Going Vessel (OGV) Model – This is an Access database model for marine 

vessels and engines. Ocean-going vessel emissions in the Final 2012 AQMP include 

CARB‟s fuel regulation for ocean-going vessels and the 2007 shore power regulation. 

In addition, the improvements and corrections include recoding the model for speed, 

updating auxiliary engine information, updating ship routing, revising vessel speed 

reduction compliance rates, and an adjustment factor to account for the effects of the 

recession. In March 2010, the International Maritime Organization (IMO) officially 

designated the waters within 200 miles of the North American Coast as an Emissions 

Control Area (ECA). Beginning August 2012, this requires ships that travel these 

waters to use fuel with a sulfur content of less than or equal to 1.0% and in 2015 the 

sulfur limit will be further reduced to 0.1%. Additionally, vessels built after January 

1, 2016 will be required to meet the most stringent IMO Tier 3 NOx emission levels 

while transiting within the 200 mile ECA zone. Outer Continental Shelf (OCS) 

emissions (i.e. emissions from vessels beyond the three-mile state waters line) are 

included in the ships emissions. The model can be downloaded from CARB‟s 

website at http://www.arb.ca.gov/msei/categories.htm#offroad_motor_vehicles

 Commercial Harbor Craft Emission Inventory Models – These are newly 

developed models. Three Access database models were developed for diesel engines
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventory

III-1-22

which are subject to regulation to reduce emissions from diesel engines on 

commercial harbor craft operated with California Waters and 24 nautical miles of the 

California baseline (Harbor Craft Rule). One model was originally developed in 2007 

to support the analysis for the Harbor Craft Rule. The other two models were 

developed to support analysis for the 2010 amendments to the rule which added 

additional vessel categories to the Harbor Craft Rule. The inventory values from the 

three models are added together to obtain the AQMP values The model can be 

downloaded from CARB‟s website at 

http://www.arb.ca.gov/msei/categories.htm#offroad_motor_vehicles

 Aircraft - The aircraft emissions inventory is updated for the 2008 base year and the 

2035 forecast year based on the latest available activity data and calculation 

methodologies. A total of 43 airports were identified as having aircraft operations 

within the District boundaries including commercial air carrier, air taxi, general 

aviation, and military aircraft operations. The sources of activity data include airport 

operators (for several commercial and military airports), FAA‟s databases (i.e., 

Bureau of Transportation Statistics, Air Traffic Activity Data System, Terminal Area 

Forecast), and SCAG. For commercial air carrier operations, SCAG‟s 2035 forecast, 

which is consistent with the forecast adopted for the 2012 RTP, reflects the future 

aircraft fleet mix. The emissions calculation methodology is primarily based on the 

application of FAA‟s Emissions and Dispersion Modeling System (EDMS) model for 

airports with detailed activity data for commercial air carrier operations (by aircraft 

make and model). For other airports and aircraft types (i.e., general aviation, air taxi, 

military), the total number of landing and takeoff activity data is used in conjunction 

with the U.S. EPA‟s average emission factors by major aircraft type (e.g., general 

aviation, air taxi, military). For the intermediate milestone years, the emissions 

inventories are linearly interpolated between 2008 and 2035.

 Locomotives – The locomotive inventories reflect the 2008 U.S.EPA locomotive 

regulations and adjustments due to the economic activity. 

Figure 1-4 shows a comparison of the off-road baseline emissions in the 2007 AQMP 

and Final 2012 AQMP. In general, the emissions are lower in the 2011 In-Use Off-Road 

Fleet Inventory model, except for 2008 SOx emissions. The projected 2008 off-road 

NOx emissions in the 2007 AQMP have 339 tons per day. The 2008 base year off-road 

NOx emissions in the Final 2012 AQMP are 208 tons per day. The 2011 In-Use OffRoad Fleet Inventory emissions are low because more rules and regulations adopted 

since 2007 OFFROAD model are included, updated data are used, and future growth

corrections and recession impact are included. The higher 2008 SOx emissions 

estimated reflects the delay in the implementation of the ocean going vessels fuel SOx 

standard.

INVENTORY TYPE

Different inventories are prepared for the Final 2012 AQMP for regulatory and SIP 

performance tracking, and transportation conformity. Two inventory types are included 

in the Final 2012 AQMP. They are annual average inventory and summer planning 

inventory. 

Average Annual Day Inventory

The average annual day emissions inventory was derived primarily by dividing the 

annual total emissions by 365, except for the emissions derived from CARB‟s 

EMFAC2011 (on-road mobile sources) and In-Use Off-Road Fleet Inventory (most offroad mobile sources) models. In addition, the average annual day inventory was 

developed for all criteria pollutants regardless of their attainment status. The average 

annual day emissions are used to estimate cost-effectiveness of proposed control 

measures and future tracking of AQMP implementation (e.g., annual progress report on 

rule adoption). 

Planning Inventory

Summer planning inventory provides the basis for tracking emission reduction progress 

specified by the federal Clean Air Act (CAA) and California Clean Air Act (CCAA). 

The CAA requires the District to produce a plan for reducing all non-attainment 

pollutants or their precursors by fifteen percent between 1990 and 1996, and three 

percent each year thereafter, averaged every consecutive three years until reaching the 

attainment date. The CCAA requires emission reductions by five percent or more per 

year, averaged every three consecutive years until 2000. In addition, the CAA specifies 

1990 as the base year, whereas the CCAA specifies 1987 as the base year. 

SCAB is designated as an extreme non-attainment area for Ozone for the federal air 

quality standards, and a non-attainment area for Ozone for the state air quality standards. 

The intent of the summer planning inventory is to characterize emission levels 

representative of those that occur during the typical season of air quality violations. The 

summer, or ozone, planning inventory contains emissions of ozone precursors (i.e. VOC 

and NOx) during the summertime.

The challenge of bringing the Basin air quality into compliance with state and federal 

ozone air quality standards is complicated by the fact that ambient concentrations of 

ozone are typically at their highest during the summer (defined as May through October 

for planning purposes). Any strategy designed to mitigate air pollution in the Basin must 

consider this summer variation in ambient air quality. 
Chapter 1: Inventory Development

III-1-25

CARB has developed guidelines for the development of planning inventories. For point 

sources emission estimates represent an “average annual operating day.” Emissions 

from point sources are calculated by dividing the total annual emissions produced by a 

source by the number of days the source was in operation. For example, if a company 

emitted 150 tons in a year and the production lines operated 5 days a week for 40 weeks, 

then the average operating emissions from this facility are calculated to be 150 tons 

divided by 200 days or 0.75 tons per day. 

For area and other mobile sources, planning emissions represent an “average seasonal 

operating day.” As an example, VOC emissions produced by asphalt road-paving 

operations are calculated by taking into account the variation in monthly levels and 

weekly operating days for paving activity during the year. Road paving varies from 

maximum rates during the summer season. Paving activity varies throughout the week 

with, on average, five operating days in a week. The allocation of annual area source 

emissions among the seasons is based on estimated relative monthly and weekly 

emissions patterns. As pointed out earlier, sources included in CARB‟s In-Use OffRoad Fleet Inventory model include seasonal activity and temperature profiles which are 

used to develop the planning inventories. CARB‟s summer planning on-road emission 

rates in the EMFAC2011 are applied to incorporate with SCAG‟s updated activity data 

in the 2012 RTP.

BASELINE EMISSION INVENTORIES

Base Year Emissions

The 2008 emission inventory is used as the base year inventory to project future year 

emissions. It represents the most recent and comprehensive inventory development. 

Attachment C lists SCAB top VOC and NOx producers which emitted equal to or 

greater than ten (10) tons per year in 2008. The total VOC emissions from these 

facilities represent 70% of the total point sources VOC emissions and 8% of the total 

stationary VOC emissions. The total NOx emissions from these facilities represent 84% 

of the total point sources NOx emissions and 29% of the total stationary sources NOx 

emissions. The stationary sources emissions result primarily from the combustion of 

fuels, evaporation of solvents or fuels, and processing of materials. Hence, stationary 

sources are grouped under fuel combustion; waste disposal; cleaning and surface 

coatings; petroleum production and marketing; industrial processes; solvent evaporation; 

and other miscellaneous processes. 

Mobile sources are divided into two source categories: 1) on-road, and 2) other (offroad) mobile sources. On-road mobile sources include light-duty passenger vehicles; 

light-, medium-, and heavy- heavy duty trucks; motorcycles; urban buses; school buses 

and motor homes. Other mobile sources include aircraft; trains; ships and commercial 

boats; off-road recreational vehicles; off-road equipment; farm equipment; and fuel 

storage and cargo handling equipment. 

Table III-2-1A compares the annual average emissions between the 2008 base year in 

the Final 2012 AQMP and the projected 2008 emissions in the 2007 AQMP by major 

source category for VOC and NOx, while Table III-2-1B compares the annual average 

emissions between the 2008 base year in the Final 2012 AQMP and the projected 2008 

emissions in the 2007 AQMP for SOx and PM2.5. Due to the economic recession which 

began in 2007, it is expected that the 2008 base year emissions should be lower than the 

projected 2008 emissions. Yet, several categories show higher emissions in the 2008 

base year in the 2012 AQMP, such as fuel consumption, waste disposal, petroleum 

production and marketing for VOC; fuel consumption for NOx; off-road emissions for 

SOx; and industrial processes for PM2.5. As mentioned earlier the differences are due to 

the methodology updates, implementation delays and inclusion of overlooked emissions.

Future Year Emissions

Future baseline emissions, assuming no additional air quality regulations are introduced, 

are given in this appendix for the years 2014, 2017, 2019, 2023, and 2030. These 

emissions are forecast from the 2008 base year by incorporating the controls 

implemented under SCAQMD rules adopted as of June 2012, and CARB adopted by 

August 2011, and a specific set of growth rates from SCAG for population, industry, and 

motor vehicle activity. Growth projections from SCAG were replaced for certain 

categories where more specific information is available to improve emission forecasts. 
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventories

III-2-4

For example, 2011 California Gas Fuel Report‟s energy demand forecasts for natural 

gas, including the energy efficiency, are used to forecast the emissions of those source 

categories. Several external adjustments are made to include CARB‟s rules adopted 

after August 2011, and emission reductions are not included in the EMFAC2011 or InUse Off-Road Fleet Inventory models. These external adjustments in the Final 2012 

AQMP include large spark ignition engines, non-agricultural internal combustion 

engines, advanced clean vehicles (LEVIII), Smog Check improvement, pleasure craft, 

and locomotives.

The impact of New Source Review and emissions budgeted for several District programs 

are addressed in the Controlled Emission Data section. Due to the adoption of the 

Regional Clean Air Incentive Market (RECLAIM) program in October 1993, emissions 

are divided into two categories, RECLAIM and non-RECLAIM. Future emissions from 

RECLAIM sources are estimated based on their allocations specified by District Rule 

2002. The methodology used to forecast emissions for non-RECLAIM sources is 

described in the following sections. Baseline emissions for future years are obtained 

using the following equation:

(F.Y.)i = (B.Y.)i(C.F.)i(G.F.)i

where (F.Y.)i is the forecast emissions of an air pollutant in the South Coast Air Basin 

for a future year. (B.Y.)i refers to the base year emissions of the air pollutant (i.e., 

2008). The control factor, (C.F.)i, is an indicator of the level of control on a specific 

source category as a result of adopted state and local air quality regulations. (G.F.)i is a 

growth factor determined for different categories of industry and socioeconomic data.

Control Factors

The impact of SCAQMD rules adopted or amended with compliance dates after 2008 are 

included in the baseline emission forecasts by means of control factors. Control factors 

were developed in reference to 2008 and applied to source categories and/or specific 

industries affected by the adopted rules/amendments. For industry, the standard 

industrial codes (SIC) system is used, and for equipment, U.S. EPA‟s SCC system is 

used. A control factor (C.F.)iis calculated by the following equation for an individual 

source category:

(C.F.)i= 1 - Control Efficiency

Control efficiency is mostly based on estimates projected during rulemaking. Control 

factors represent the remaining emissions after a rule or regulation is implemented after 
Chapter 2 Summary of Emissions

III-2-5

2008. Table III-2-2 lists control factors for the years 2014 and 2023 for District rules 

with post-2008 compliance dates. 

Growth Factors

For growth purposes, facility business type is assigned to the facilities based on North 

American Industry Classification System (NAICS) Code according to their primary 

activity. Growth projections by NAICS were developed by SCAG. The Final 2012

AQMP growth data is based on SCAG‟s 2012 RTP. The data was adjusted with the 

most recent data from Bureau of Labor Statistics (BLS), California Department of 

Finance (DOF), California Employment Development Department and U.S. Census 

Bureau (Census). The SCAG‟s 2012 RTP growth estimates are lower than SCAG‟s 

2008 RTP for the following reasons: (1) Recent population projections from BLS, DOF 

and Census indicate that SCAG region will face significant slow growth, which will 

affect long-term employment growth in SCAG region. This is due to the aging trend of 

the baby-boomer population and the recessionary impacts; (2) The Final 2012 AQMP

employment growth is adjusted by both the economic recession and globalization. Since 

the employment forecast is based on a historical trend, sluggish job growth in recent 

years translates into slower short-term and long-term employment growth for the SCAG 

region.

Each emission inventory source grows based on its growth surrogate. Growth surrogates 

include industry output growth, employment growth, demographic growth and others. 

The selection of the surrogate by which emission growth is projected depends on the 

type of activity. For instance, manufacturing sectors use output growth as surrogate. 

Output growth is the product of employment and productivity. Employment growth is 

chosen for labor intensive sectors, such as construction and laundering. Certain emission 

sources use demographic data as their surrogate, such as architectural coatings (housing 

units as surrogate) and composting (population as surrogate). Some growth projections 

are from CARB‟s special studies or Southern California Gas Company 2011 Gas Fuel 

Report for natural gas combustion related categories.

Emission Trend Analysis

Figures 2-1 through 2-4 present the relative contributions by source categories (i.e., 

point, area, on-road, and off-road) to total emission levels in 2008 annual average (VOC, 

NOx, CO, SOx and PM2.5), 2008 summer planning (VOC and NOx), 2023 annual 

average (VOC, NOx, CO, SOx and PM2.5) and 2023 summer planning (VOC and 

NOx), respectively. As seen in the figures, in 2008 (average annual day) on-road and 

off-road mobile sources are major contributors of CO (95 percent), NOx (88 percent), 

SOx (75 percent) and VOC (57 percent) emissions. Top fine particulate matter (PM2.5) 

producers include cooking (14%); residential fuel consumption (10%); and entrained 

road dust (10%). For 2023 (average annual day), mobile sources continue to be major 

contributors to total CO and NOx emissions by approximately 90 percent, 78 percept, 

respectively. However, contribution to VOC and SOx by mobile sources is reduced due 

to CARB regulations over time. Area sources become major contributors to VOC

emissions (from 38 percent in 2008 to 53 percent in 2023). Figures 2-5 through 2-8

illustrate the emission trends by pollutant (VOC, NOx, PM2.5, and SOx) for 2008, 2014, 

2019, and 2023 respectively.

VOC Emissions

As presented in Figure III-2-5, emissions from area sources, off-road mobile sources and 

on-road mobile sources all show a significant decrease over time. Between 2008 and 

2023, summer planning VOC emissions from off-road mobile sources are expected to 

fall from 162 tons per day to 108 tons per day, while on-road emissions should fall from 

213 tons per day to 70 tons per day. Area source reductions are derived mainly from 

the SCAQMD‟s adopted rules for architectural coatings (Rule 1113), refinery flares 

(Rule 1118), greenwaste composting operations (Rule 1133.3), consumer paint thinners 

and multi-purpose solvents (Rule 1143) and metalworking fluids and direct-contact 

lubricants (Rule 1144). Off-road reductions result primarily from turnover to cleaner 

off-road equipment, pleasure craft and off-road recreational vehicles. Since its adoption 

in 1990, California‟s Low Emission Vehicle I (LEV I) program has produced significant 

emission reductions from on-road passenger vehicles by relying on a systems-wide 

approach to achieve reductions from fuels and mobile source exhaust and evaporative 

emissions. Both LEV I and LEV II, adopted in 1998, include four primary elements: (1) 

increasingly stringent exhaust emission standards, (2) an increasingly stringent annual 

fleet average standard for Non-Methane Organic Gas (NMOG), (3) banking and trading 

provisions, and (4) a requirement that a specific percentage of vehicles be Zero Emission 

Vehicles (ZEVs), vehicles with no emissions. Under LEV II, sport utility vehicles, pickup trucks, and mini-vans must achieve the same emission standards as cars, beginning in 

2004-2007. Additional VOC emission reductions are from the adoption of the LEV III 

program. 

NOx Emissions

Figure III-2-6 illustrates the NOx emissions by major source category. Summer 

planning NOx emissions are projected to decrease from both off-road mobile (208 tons 

per day to 133 tons per day) and on-road mobile (426 tons per day to 117 tons per day) 

sources from 2008 to 2023. The on-road reductions largely reflect the cleaner in-use 

heavy-duty trucks and buses. Reductions from on-road emissions are also projected for 

light- and medium-duty vehicles through the adoption of the LEVIII program with more 

stringent tail-pipe and greenhouse gas standards for light- and medium-duty vehicles. 

Off-road NOx emission reductions result primarily from cleaner in-use off-road 

equipment (over 25 horse power); ship auxiliary engine cold ironing & clean 

technology; cleaner main ship engines.
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventories

III-2-52

PM2.5 Emissions

Figure III-2-7 shows the PM2.5 emission trend. A good portion of the emissions are 

from dust. The projected dust inventories in 2008 and 2023 for paved and unpaved 

roads are both 8 tons per day (annual average inventory).

SOx Emissions

Figure III-2-8 illustrate the SOx emissions trend. The significant decrease in SOx 

emissions between 2008 and 2014 (from 54 tons per day to 18 tons per day) is due to the 

full implementation of the SOx RECLAIM and implementation of the cleaner sulfur 

content marine fuels. 

Impact of Growth

The Final 2012 AQMP forecasts the 2030 emissions inventories „„with growth‟‟ through 

a detailed consultation process with the Southern California Association of Governments 

(SCAG). The region is likely to see a 16% growth in population, 18% growth in housing 

units, 16% growth in employment, and 11% growth in vehicle miles traveled between 

2008 and 2030. To illustrate the impact of demographic growth on emissions, year 2030 

no-growth emissions were estimated by removing the growth factors from the 2030 

baseline emissions. Table III-2-15 presents the comparison of the projected 2030 

emissions with and without growth. It should be noted that in this analysis, the benefit of 

potential applications of BACT under New Source Review (NSR) is not included. The 

growth impacts to year 2030 for VOC, NOx, CO, SOx and PM2.5 are 77, 76, 311, 5 and 

11 tons per day respectively. 

General Conformity Budget

U.S. EPA‟s General Conformity rule (40 CFR part 93, subpart B, and 40 CFR Part 51, 

Subpart W, as adopted by reference in SCAQMD Rule 1901, September 1994) 

establishes an applicability test for determining which Federal actions are subject to the 

conformity requirement for the nonattainment or maintenance areas. If a proposed action 

results in emissions increases which are less than the de minimis thresholds for the 

relevant pollutants or precursors, then no conformity determination needs to be made. If 

the emissions from a proposed action exceed the de minimis threshold for any given 

pollutant (or precursor) for which the area is designated as maintenance or in 

nonattainment, then the Federal agency must make a positive conformity determination 

for that pollutant(s) on the basis of one of the criteria listed in 40 CFR 93.158 before the 

project can proceed. The conformity determination must demonstrate that the emissions 

from the proposed project are accounted for in the most recently approved SIP. The 
Chapter 2 Summary of Emissions

III-2-53

South Coast Air Basin is designated as an extreme nonattainment area for ozone and as a 

nonattainment area for PM2.5. The general conformity de minimis threshold is 10 tons 

per year of VOC and 10 tons per year of NOx for the extreme ozone nonattainment areas; 

and 100 tons per year of PM2.5 for the PM2.5 nonattainment areas.

Based on historical records none of the projects requiring general conformity 

determinations received by the District exceeded the PM2.5 threshold. Rather, NOx is 

the main pollutant of concern, with emissions occurring primarily during the two to three 

year construction phase of projects. To streamline the review process and to facilitate the 

conformity determination, two separate VOC and NOx general conformity budgets are 

established: 1 tpd of NOx and 0.2 tpd of VOC are set aside for this purpose every year,

starting in 2013 until 2030, from the projected emission growth in the Final 2012 AQMP. 

This set aside account will be re-evaluated in the next AQMP for need and adequacy 

based on the data gathered at that time. These set-aside emissions in the Final 2012 

AQMP represent less than 1% and 2% of projected mobile source growth in emissions 

shown in Table 2-15 for VOC and NOx, respectively.

The District will set up a tracking system for projects requiring conformity 

determinations on a first come first serve basis. The District will debit the project 

emissions from the applicable set aside accounts until it is depleted. The unused portion 

cannot be carried forward to the following year. For those projects that come in after the 

conformity budget is exhausted, the corresponding federal agency will have to go through

the regular general conformity determination process to demonstrate that these emissions 

are accounted for in the SIP. The set aside accounts will be revised and updated via 

AQMP/SIP revisions.

Southern California Edison (SCE) is currently in the process of, or has plans to construct 

six linear transmission line projects which would traverse federal lands within the 

jurisdiction of the District. The projects are: (1) Devers-Palo Verde NO. 2 Transmission 

Project (DPV2); (2) Tehachapi Renewable Transmission Project (TRTP); (3) Falcon 

Ridge Substation Project (Falcon Ridge); (4) Path 42 Upgrade Project (Path 42); (5) West 

of Devers Interim Project (WOD Interim); and (6) West of Devers Upgrade Project 

(WOD Upgrade). SCE submitted to the District the NOx emissions estimates expected to 

be generated during the construction of these transmission lines from 2012 and 2022. 

The total estimated NOx emissions from these six projects within the South Coast Air 

Basin are 95 tons per year for 2012; 55 tons per year for year 2013; 10 tons per year for 

year 2014; 20 tons per year for 2015; 50 tons per year for 2016 and 2017; and 20 tons per 

year for 2018 through 2022. These emissions have been accounted for in the general 

conformity set aside account for NOx. 
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventories

III-2-54

Pre-Base-Year Offsets

The District‟s growth projections include pre-base year emissions, consistent with the 

requirements of 40 CFR § 51.165(a)(3)(i)(C)(1). To the extent offsets are required under 

NSR for permitted facilities to be sited or expanded in this region, pre-2008 emission 

credits authorized under District‟s Reg XIII can be used and are explicitly identified and 

accounted for in the Final 2012 AQMP through growth projections, up to the amounts 

shown in Table III-2-15. While Table III-2-15 includes projected growth in certain 

sources not subject to NSR, the AQMP does not limit growth to individual source 

categories. Therefore, Table III-2-15 explicitly identifies pre-base-year offsets in the 

amounts up to the difference between the growth and no-growth projections for the point 

and area source categories that are potentially subject to NSR and could potentially 

require the use of pre-base-year offsets. See 57 Fed. Reg. 13,498.

This growth presents a formidable challenge to our air quality improvement efforts,

because the projected growth will offset the impressive progress made in reducing VOC 

and NOx and PM2.5 emissions through adopted regulations. Meeting U.S. EPA‟s current 

and future more stringent air quality standards will require the continuation of aggressive 

emissions reductions efforts from all levels of government.

It should be noted that the AQMP is designed to accommodate growth. Therefore, the 

proposed control measures are sufficient to reduce emissions while allowing growth. 

For permitted stationary sources, offsets are required under the federal and state new 

source review programs. To the extent offsets are required, either via the open market 

trades or accessing the District‟s R1315 bank, pre-2008 emission credits can be used and 

these emissions are accounted for in the SIP through growth projections as shown in 

Table III-2-15. However, It needs to be emphasized that AQMP emissions reflect 

projected actual emissions for the source category, not potential to emit or allowable 

emissions and do not include offset ratio greater than one for certain pollutants.

UNCERTAINTY IN THE INVENTORY

An effective AQMP relies on an adequate emission inventory. Over the years, 

significant improvements have been made to quantify emission sources for which 

control measures are developed. Increased use of continuous monitoring and source 

tests has contributed to the improvement in point source inventories. Technical 

assistance to facilities and auditing of reported emissions by the District also have 

improved the accuracy of the emissions inventory. Area source inventories that rely on 

average emission factors and regional activities have inherent uncertainty. Industryspecific surveys and source-specific studies during rule development have provided 

much-needed refinement to the emissions estimates.

Mobile source inventories remain the greatest challenge due to the constantly new 

collected information from the large number and types of equipment and engines. Every 

AQMP revision provides an opportunity to further improve the current knowledge of 

mobile source inventories. The Final 2012 AQMP is not an exception. As described 

earlier, many improvements were made to EMFAC2011 and such work is still ongoing. 

However, it should be acknowledged that there are still areas that could be significantly 

improved if better data were available. Technology change and improvement in the area 

of electric, hybrid, flexible fuel, and fuel cell vehicles, or the change in future gasoline 

prices, all add uncertainty to the on-road emissions inventory. 

Additionally, the latest recession started in 2007. The recession was unforeseen and was 

not considered in the 2007 AQMP. As we prepare the Final 2012 AQMP, we are still in 

the midst of economic recovery. The impact of this recession is deep and thus adds to 

the uncertainty in the emissions provided here. Relative to future growth, there are many 

challenges with making accurate projections, such as where vehicle trips will occur, the 

distribution between various modes of transportation (such as trucks and trains), as well 

as estimates for population growth and changes to the number and type of jobs. 

Forecasts are made with the best information available; nevertheless, they contribute to 

the overall uncertainty in emission projections. Fortunately, AQMP updates are 

generally performed every three to four years; thereby allowing for frequent 

improvements to the inventories.

CONTROLLED EMISSION INVENTORIES

This section describes the methodology used to estimate the controlled and remaining 

emissions after the proposed control measures in the Final 2012 AQMP are implemented 

for the years 2014 and 2023. Emission reductions are derived by applying the control 

efficiency of a control measure to the projected baseline inventories. In addition to the 
Chapter 2 Summary of Emissions

III-2-57

proposed control measures, the impacts of phase-out VOC and SIP Reserve set aside 

tracking and other budgeted emissions for various District programs are also discussed 

in this section.

To project emission reductions and remaining emissions from the implementation of the 

proposed control measures, a mathematical algorithm called Controlled Emissions 

Projection Algorithm (CEPA) is used. CEPA is developed to calculate projected 

remaining emissions and/or emission reductions for specified control scenarios. CEPA 

is briefly discussed in this section. A more comprehensive and extensive discussion of 

CEPA is presented in Technical Report III-A of the 1991 AQMP.

Since 1998, the District has been implementing several funding incentive programs for 

the replacement or retrofit of heavy duty diesel vehicles, including the Carl Moyer and 

Lower Emission School Bus programs, Proposition 1B Goods Movement program, and 

the SOON off-road equipment program. Over the years, thousands of diesel engines in 

the on-road and off-road sectors have been converted to natural gas, repowered, or 

retrofitted with particulate traps to achieve significant emissions reductions.

Based contracts awarded and executed since the 2007 AQMP under the Proposition 1B 

and Carl Moyer programs, the typical useful life of the vehicles, and the expected 

emissions benefits in 2014 beyond the benefits included in the future-year baseline 

inventory, an additional 16 tons/day of NOx emissions reductions, 0.28 tons/day of VOC 

emissions reductions, and 0.46 tons/day of direct PM2.5 emissions reductions will be 

achieved in 2014. These contracts continue to be closely tracked and the resulting level 

of emission reductions will be confirmed once achieved. The District has dedicated staff 

performing field audits to ensure that the agreed upon protocols are followed. Based on 

past contract performance, emission reductions from these awarded contracts were 

discounted by 30 percent to reflect the fact that occasionally, contract awards are not

Table III-2-16 summarizes emission reductions in 2014 from the mobile source 

incentive programs. It should be noted that these surplus reductions, attributable to 

accelerated fleet turnover or early compliance with state regulations, will diminish over 

time given that the baseline emissions inventory already incorporates normal fleet 

turnover and rule compliance.

Emission Impacts of SCAQMD Programs 

There are several District regulatory programs that have specific impacts on future 

emissions through certain “set-aside” or exemption provisions. As a result, special 

emission accounts were created for the Final 2012 AQMP to track these emissions. For 

air quality modeling purposes, these emissions (except RECLAIM allocations) are 

distributed across the entire non-RECLAIM point source.

SIP Set Aside Accounts

 Background 

The Final 2012 AQMP includes a few accounts to track growth from emission trade-offs 

from regulatory programs, and a SIP Reserve for potential technology assessments

(Table III-2-17). The methodology and assumptions used to develop these tracking

accounts for the Final 2012 AQMP are discussed in detail below. It should be noted that 

emission increases or decreases discussed herein are in reference to the projected AQMP 

baseline.

 VOC Emissions from Phase-Out of Toxics

Due to increasing focus on air toxic controls certain amount of conversion from toxics to 

VOCs may be inevitable in the future. Therefore, three tons per day are included for 

potential VOC emission increases to reduce toxics, such as controlling of methylene 

chloride in coating stripping applications may increase VOC emissions. 

 SIP Reserve for Potential Technology Assessments 

To achieve air quality goals, adopted and amended rules and regulations that rely on 

technology forcing emission limits are often needed. Technology forcing emission 

limits are designed to provide ample time for the development and implementation of 

new air pollution technologies. In the event, however, that the new air pollution control 
Chapter 2 Summary of Emissions

III-2-59

technology does not come to fruition by the implementation date of the adopted or 

amended rule there may be a need to delay or relax the future emission limits. The SIP 

Reserve is designed to ensure that delaying or relaxing future emission limits for 

technology forcing rules will not interfere with the Basin‟s attainment demonstration. In 

addition, the SIP Reserve allows the District to adopt and amend rules with technology 

forcing limits, while maintaining SIP approvability if a rule relaxation or delay is 

needed.

The potential delay of R1110.2 biogas engine reductions beyond 2014 was included in 

the estimates for 2011.

Proposed Control Measures

In order to assess emission reduction potential and remaining emissions from proposed 

control measures, a control factor profile needs to be developed identifying source 

category targeted by a measure, its control efficiency, and implementation schedule.

Control Efficiency/Control Factor

One factor that determines the effectiveness of a control measure is its control efficiency 

(CE), expressed in percentage. Control efficiency is dependent on the specific control 

technologies proposed, and each control measure may have one or more technology 

options available. If there is only one feasible control technology in a control measure, 

its control efficiency is primarily based on an engineering evaluation of the proposed 

technology. However, if several control technologies are available to control an 

emission source, the average control efficiency is used. If multiple control technologies 

are proposed to reduce emissions from various steps of an operation, a weighted average 

control efficiency is developed to represent an overall control of the emission sources. 

Once the control efficiency of a control measure is determined, it is used to estimate 

emission reductions of the proposed measure. Control efficiencies for the proposed 

control measures are identified and discussed in detail in Appendix IV of the Final 2012

AQMP.
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventories

III-2-60

The control factor (CF) is used to estimate remaining emissions once a proposed control 

measure is implemented. A control factor equal to 0 indicates complete emission control 

or 100 percent efficiency. A control factor equal to 1 indicates no emission control or 

emissions remain unchanged. A high control factor value indicates a low control 

efficiency. As the control efficiency goes up, the control factor value goes down. The 

equation to calculate a control factor follows:

CF = 1 - (CE/100)

And, the remaining emissions can be calculated as:

REM = BE * CF

Where REM is Remaining Emissions, and BE is Baseline Emissions

The Final 2012 AQMP has many milestones for which emission reduction progress 

needs to be projected. As a result, control factors for each milestone year were 

developed. The control factor profile for each measure is developed considering the 

following factors:

 proposed adoption date;

 implementation lead time; and

 phase-in period, if any.

The adoption date as proposed in the Final 2012 AQMP is the date the District or other 

agency is expected to adopt the control measure as a rule. The implementation lead time 

reflects the time allowed for the emission sources to install controls. When a rule is 

implemented, it is not unusual that it may have multiple interim implementation dates 

prior to full implementation. This is because the requirements in a rule may require two 

or three phases to reach the final emission target (e.g., a technology-forcing regulation). 

Or, a rule may regulate such a large population of equipment that it is impractical to 

implement it all at once, and it becomes administratively necessary to phase in its 

implementation. In either case, a control profile would indicate an initial 

implementation date and an ending implementation date. The adoption and 

implementation schedule of the proposed control measures is presented in Chapter 4 of 

the Final 2012 AQMP.
Chapter 2 Summary of Emissions

III-2-61

Impact Factors

Each proposed control measure describes specific emission sources subject to potential 

controls. Based on the description of these sources, corresponding sources as tracked in 

the emission inventory are identified. In general, emission sources are grouped by major 

source category, which can be further subcategorized into point sources denoted by 

Source Classification Codes (SCC) and area sources denoted by Category Emission 

Source (CES) Codes. To track emission reductions more accurately, the control factors 

at the SCC/CES level become necessary.

An SCC, an 8-digit EPA code, is used to identify emissions from a point source at the 

equipment level. A CES, a 5-digit CARB code, is used to describe an area source for 

which emissions are distributed across the region with no specific locations.

For some measures the controls apply not only to the type of equipment, but also to the 

industries engaged in a particular activity. In those cases, control factors will be 

developed by pairing SCCs and Standard Industrial Classification (SIC) Codes to clearly 

and specifically point out the emission sources in the inventory that the measure is 

designed to reduce. Such SCC/SIC pairs significantly enhance the ability to quantify 

emissions closely following the intent of a proposed control measure.

There are instances where an SCC or CES category is not fully impacted by a control 

measure. As a result, an impact factor (IF) is developed as a weighing factor for such an 

adjustment. The following equation illustrates how the impact factor (IF) is included in 

the CF calculation. 

CF = 1 - ( (CE /100) x IF )

Impact factors will accurately track the measure‟s baseline emissions, and calculate more 

accurate reductions from the proposed control measures.

CEPA Emission Calculations

The District uses the CEPA program to calculate emission projections for the proposed 

AQMP control measures. Based on the control factor profile and projected baseline 

emissions, CEPA estimates emission reductions and remaining emissions for future 

years by pollutant (i.e., summer VOC and NOx; winter CO and NO2; and average annual 

day for VOC, NOx, CO, SOx and PM10).

CEPA allows interaction of multiple control measures affecting a specific emission 

source, avoiding double counting of emission reductions from additional measures. It 
Final 2012 AQMP: Appendix III Base and Future Year Emission Inventories

III-2-62

also provides flexibility in analyzing various scenarios and improves accuracy by 

standardizing calculation methodologies. 

To run CEPA, the program requires four data input files. These input files are as 

follows:

1. Master Measure File - This file contains all the measures proposed in the 

AQMP. There is one master measure file in the CEPA program.

2. Scenario File - This file is a listing of selected measures to characterize 

emission reductions, and is a subset of the master measure file. For example, it 

can contain a group of control measures for mobile sources only, or a group of 

measures to be implemented by U.S. EPA. 

3. Control Factor File - This file shows control factor by pollutant by SCC/SIC 

(or CES/CES) pairs for each control measure in a specified year.

4. Baseline Emission File - This file contains projected emission data (tons per 

day) for future years based on the 2008 emissions inventory. There are

different types of baseline emission data available for CEPA runs. These are 

the average annual day emissions inventory with pollutants VOC, NOx, CO, 

SOx, PM10; and PM2.5; and the planning inventory with pollutants VOC and 

NOx during summer, and CO and NO2 during winter. 

CEPA calculates the remaining emissions at the SCC/SIC level. It can generate many 

types of emission summary reports or electronic files. For example, the program can 

provide composite control factors for on-road mobile sources in sixteen categories used 

in the air quality modeling analysis or composite control factors from all the proposed 

control measures in the scenario file. It can also provide remaining emissions by 

SCC/S1C or CES/CES pairs; by major source category; or by SIC. It can present 

emission reductions by each control measure in the absence of other competing 

measures; or reductions for each control measure following a pre-determined 

implementation sequence. The result of CEPA runs will be presented in Appendix V of 

the Final 2012 AQMP. 

CARB Emission Data Reports System

As mentioned in Chapter 1, of this appendix the entire emission inventories are compiled 

and maintained by CARB in its statewide emission related information databases named 

California Emission Inventory Development and Reporting System (CEIDARS), and 

California Emission Forecasting and Planning Inventory System (CEFIS). 
Chapter 2 Summary of Emissions

III-2-63

In both systems, emissions are tracked by CARB‟s coding method called Emission 

Inventory Codes (EIC code). The EIC code is a 14-digit number arranged into four 

fields: major category, source category, material description and emission sub-category. 

For example, EIC 210-200-3300-0000 is for dry cleaning using perchloroethylene. 210 

indicate that this source is under laundering group. 200 means the source category is dry 

cleaning. 3300 refers to the material perchloroethylene. 0000 implies there is no subcategory for this particular source. EIC separates emission sources into four major 

divisions: stationary, area, non-anthropogenic, and mobile source. This coding system 

allows flexibility in how sources are selected, sorted and grouped to fit users‟ needs. 

EIC links area sources and point sources together to allow a computer program to 

automatically reconcile point and area source emissions. In the Final 2012 AQMP, all 

the emission summary reports are based on CARB‟s EIC codes. Because only the 

anthropogenic sources are included in this document, all summary reports in appendices 

include three major divisions. They are stationary, area, and mobile source.
