Executive Summary 

ES. Executive Summary 

The State of Colorado Air Pollution Control Division (APCD) is currently in the process of updating 

the carbon monoxide (CO) and particulate matter (PM10) maintenance plans covering the Denver 

metropolitan area. The City and County of Denver Department of Aviation (Department of 

Aviation) wishes to provide information to the APCD specific to and consistent with current 

planning efforts and activity at Denver International Airport (DIA) for incorporation into the updated 

maintenance plans. The Department of Aviation previously submitted airport emissions data to 

APCD in support of the CO State Implementation Plan (SIP) in 1999, the ozone (O3) SIP in 2000, 

and the PM10 SIP in 2001. For the 2005 revisions to the CO and PM10 plans, the Department of 

Aviation prepared a Protocol Document [ES-1] with APCD guidance. This Airport Emissions 

Inventory follows the methodologies outlined in the Protocol Document. 

This document presents the data and estimating approach used to prepare airport emission inventories 

for Denver International Airport for the following analysis years: 2001, 2009, 2010, 2013, 2015, 

2020, 2025, and 2030. The document is organized into four sections and several technical 

appendices. Section I “Introduction” provides some background information regarding the air 

quality status of the Denver metropolitan area, pollutants evaluated in the airport emissions inventory 

study, and sources of emissions at Denver International Airport that were quantified as part of the 

study. Section II “Operational Emissions” provides information regarding emissions from airport 

operational sources including aircraft, auxiliary power units, ground support equipment, City support 

equipment, minor point sources, firefighting training, and unpaved roads. Section III “Construction 

Emissions” provides information regarding emissions from airport construction sources including 

land development, asphalt paving, concrete batching, asphalt batching, and construction equipment. 

This executive summary provides a summary of total airport-related emissions for each of the 

analysis years described above. Tables ES-1 through ES-5 provide estimates of emissions (tons per 

year and tons per day) for each source and analysis year. The following criteria pollutants were 

evaluated: CO, PM10, sulfur dioxide (SO2), and ozone precursors: volatile organic compounds 

(VOC) and oxides of nitrogen (NOx). For the purposes of this study oxides of sulfur (SOx) were 

assumed to be equivalent to SO2 . 

Tons per day data provided in Tables ES-1 through ES-5 were calculated by dividing the annual 

emissions data by 365 days; therefore, the tons per day numbers represent an annual average day and 

not a “winter” day. Nevertheless, seasonality was considered during the development of the Airport 

Emissions Inventory and, as discussed in the Protocol Document, some airport-related emission 

sources were excluded from the analysis since APCD is developing a “winter” emissions inventory 

in support of the updated CO and PM10 maintenance plans. Airport-related sources of emissions that 

were not considered in this study include agricultural operations and oil field construction. In 

hindsight the City and County of Denver Department of Aviation has decided that the Airport 

Emissions Inventory would have been more comprehensive if these sources had been addressed, and 

respectfully requests that these sources be evaluated and added to the Airport Emissions Inventory 

when the APCD initiates its update to the Ozone maintenance plan. 

Appendix G “Grids for Regional Air Quality Modeling” contains the Department of Aviation’s 

recommendations regarding the apportionment of airport-related emissions to APCD’s grid cells in 

support of future regional air quality modeling to be conducted by APCD.

Airport Emissions Inventory June 29, 2005 

For Inclusion in the State Implementation Plans FINAL DRAFT 

Section I: Introduction 

I-1

I. Introduction 

The State of Colorado Air Pollution Control Division (APCD) is currently in the process of updating 

the carbon monoxide (CO) and particulate matter (PM10) maintenance plans covering the Denver 

metropolitan region. The City and County of Denver Department of Aviation (Department of 

Aviation) wishes to provide information to the APCD specific to and consistent with current 

planning efforts and activity at Denver International Airport (DIA) to ensure that accurate 

information regarding sources of emissions at DIA is incorporated into the updated maintenance 

plans. This document presents the data and modeling approach used to prepare the airport emission 

inventories for DIA. 

1.1 Background 

The federal Clean Air Act of 1970 [I-1], as amended, requires that states identify those areas where 

the National Ambient Air Quality Standards (NAAQS) are not met for specific air pollutants. The 

U.S. Environmental Protection Agency (USEPA) has designated such areas as nonattainment areas. 

A State with a nonattainment area must prepare a State Implementation Plan (SIP) that details the 

programs and requirements that the State will use in order to meet the NAAQS by the deadlines 

specified in the Clean Air Act Amendments of 1990 (CAAA) [I-2]. 

The USEPA, pursuant to mandates of the CAAA, has established primary and secondary NAAQS for 

seven air contaminants, known as criteria pollutants [I-3]. These criteria pollutants are: carbon 

monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM10 and PM2.5), lead (Pb), 

and sulfur dioxide (SO2). The primary standards were established at levels sufficient to protect 

public health with an adequate margin of safety. The secondary standards were established to protect 

public welfare from other adverse effects of air pollution. 

Nonattainment areas that are brought into attainment for the NAAQS are reclassified as maintenance 

areas for criteria pollutants. For these areas, a State must convert its regional plan into a maintenance 

plan. The USEPA has defined two types of maintenance areas. The first classification is a transport 

maintenance area, which means that the pollutants found in the region are transported in by trade 

winds from another region. The second classification is for a non-transport maintenance area, which 

means that the pollutants are produced in the region. The Denver metropolitan area is considered a 

non-transport maintenance area. 

1.1.1 Denver SIP Status 

The air quality of the region in which Denver is located is managed via SIPs for three criteria 

pollutants: carbon monoxide (CO), ozone (O3), and particulate matter with an aerometric diameter 

less than or equal to a nominal ten micrometers (PM10). Historically, the Denver metropolitan area 

was determined to be a nonattainment area for each of these criteria pollutants; however, Denver's air 

quality has improved dramatically over the past thirty years. A description of the air quality status 

for each of the relevant criteria pollutants is given below. 

 

• Effective October 11, 2001, the USEPA redesignated the Denver metropolitan area as 

attainment for ozone. With this designation, the area is classified as a maintenance area for 

ozone through 2014 [I-4]. In 2003, however, the Denver metropolitan area officially violated 

the 8-hour ozone standard, the “new” ozone standard promulgated by USEPA in July 1997. 

In anticipation of violations and to reduce ozone levels, a number of agencies in the Denver

Section I: Introduction 

I-2

metropolitan area entered into an ozone Early Action Compact (EAC) with USEPA in 

December 2002. An EAC allows a region to submit an enforceable plan outlining steps the 

region will take to maintain compliance with the ozone standard. In return, the USEPA will 

defer any potential nonattainment designation and give the area until 2007 to demonstrate 

attainment with the standard. Under the EAC, which was amended in early 2004, Denver 

retains its ozone maintenance area status until at least 2007 despite the violation of the 8-hour 

ozone standard in 2003. 

• Effective January 14, 2002, the USEPA redesignated the Denver metropolitan area as 

attainment for carbon monoxide. With this designation, the area is classified as a 

maintenance area for carbon monoxide through the year 2014 [I-5]. 

• Effective October 16, 2002, the USEPA redesignated the Denver metropolitan area as 

attainment for PM10. With this designation, the area is classified as a maintenance area for 

PM10 through the year 2015 [I-6]. 

1.1.2 Pollutants Studied 

The pollutants evaluated in the airport emissions inventories include carbon monoxide; ozone 

precursors: volatile organic compounds (VOC) and oxides of nitrogen (NOx); and PM10. PM10 can 

also be formed from the interaction of SOx and NOx emissions, commonly called secondary 

particulates. These secondary particulates are not emitted as PM10 directly, but are formed in the 

atmosphere through complex chemical reactions and conditions. SOx emissions from airport 

operational and construction sources have been included in the Airport Emissions Inventory for 

information purposes. Denver International Airport is not a significant source of lead; therefore, for 

purposes of this study, lead emissions were not quantified. In addition, PM2.5 was not quantified in 

this study because the entire state of Colorado is classified as attainment for PM2.5. 

1.2 Estimating Tools 

The development of the airport pollutant emissions inventory was conducted using the Emissions and 

Dispersion Modeling System (EDMS) and other industry-accepted computer models and techniques. 

EDMS is the Environmental Protection Agency’s (USEPA’s) preferred guideline model for air 

quality analyses at airports [I-7]. EDMS is a combined emissions and dispersion model developed by 

the Federal Aviation Administration (FAA) in cooperation with the United States Air Force (USAF) 

in the mid-1980s. The primary applications of the model are (1) generating an inventory of 

emissions caused by sources on and around an airport or air base and (2) calculating pollutant 

concentrations in the surrounding environment. System data tables include emission factors for 

civilian and military aircraft, civilian ground support equipment, and civilian motor vehicles. Both 

the emissions inventory and dispersion modeling modules interact with the system database to 

retrieve and store data. 

The EDMS emissions inventory module incorporates USEPA-approved methodologies for 

calculating aircraft emissions, on- and off-road vehicle emissions, and stationary source emissions. 

Pollutants currently included in EDMS for emissions inventories are carbon monoxide (CO), 

hydrocarbons (HC), volatile organic compounds (VOC), oxides of nitrogen (NOx), oxides of sulfur 

(SOx), and particulate matter less than 10 microns in diameter (PM10). 

In 2001, the FAA re-engineered EDMS to incorporate new data and algorithms and released EDMS 

Version 4.0. The FAA subsequently released Versions 4.1, 4.11, 4.12 and 4.2 of the EDMS. EDMS 

4.2 is the most current release of the model and was used for the Airport Emissions Inventory study.

Section I: Introduction 

I-3

EDMS Version 4.2 includes advances in data inputs for aircraft performance and auxiliary power 

units (APUs) and new data for dispersion. 

1.3 Airport Emissions Sources 

Estimates of emissions generated by Airport-related sources were prepared for the baseline year 

(2001) and eight future years (2009, 2010, 2013, 2015, 2020, 2025, and 2030). Sources of emissions 

that were included in this study are identified in Table I-1. Onroad vehicle traffic emissions at the 

Airport, of which, construction employee vehicle trips and construction hauling trips are a part, are 

accounted for in transportation conformity models developed by the Denver Regional Council of 

Governments (DRCOG) for the Denver metropolitan area and therefore were excluded from the 

Airport Emissions Inventory study. For the purposes of the documentation the sources of emissions 

have been divided into two primary categories: airport operational emissions and construction 

emissions, which are discussed in Section II and Section III, respectively.

II. Operational Emissions 

2.1 Aircraft 

For the purposes of the Airport Emissions Inventory, aircraft emissions include emissions generated 

by aircraft engines while aircraft are in flight, taxiing, or idling and emissions from on-board 

auxiliary power units (APUs). These emission sources are described in the sections that follow. 

2.1.1 Aircraft Operations 

Annual aircraft emissions are a function of the number of annual aircraft operations expressed as 

landing and takeoff (LTO) cycles, the aircraft fleet mix (types of aircraft used), and the length of time 

aircraft spend in each of the four modes of operation defined in EDMS: takeoff, climbout, approach, 

and idle. For emissions calculations, the EDMS treats the takeoff mode as the time from the start of 

the takeoff roll until an aircraft reaches 1,000 feet above the ground. The climbout mode begins at 

1,000 feet above the ground and ends when the aircraft reaches the mixing height. The mixing height 

is set to 3,000 feet above the ground by default. The approach mode begins at the mixing height and 

ends when the descending aircraft reaches the ground. The idle mode is the sum of the landing roll 

time, the taxi time, and the time an aircraft spends in queue. 

The EDMS database contains an expansive list of aircraft types (airframes) and engine types for use 

in air quality analyses. Aircraft emissions are estimated using emission factors associated with 

particular engine types and operating modes. Aircraft emission factors included in the EDMS 4.2 

database are based on information from engine manufacturers, information contained in the 

International Civil Aviation Organization (ICAO) Aircraft Engine Exhaust databank, and data 

provided in the USEPA’s Procedures for Emission Inventory Preparation. Volume IV: Mobile 

Sources [II-1]. EDMS is not capable of estimating PM10 emissions from aircraft engines. PM10

emission factors used in the Airport Emissions Inventory study were derived from the USEPA’s 

Draft 2002 National Emissions Inventory [II-2] and are specific to DIA. The baseline year (2001) 

and future year aircraft emissions estimates are discussed in the sections below. 

2.1.1.1 Baseline Emissions 

The baseline year aircraft emissions inventory was estimated in EDMS 4.2 using aircraft operations 

data obtained from the Department of Aviation and the FAA’s Air Traffic Activity Data System 

(ATADS) on-line database. EDMS aircraft fleet mix data used in the calculation of the 2001 

baseline emissions inventory was developed using electronic data from the Department of Aviation’s 

aircraft noise monitoring system (ANMS) for calendar year 2001 [II-3]. Information obtained from 

the U.S. Bureau of Transportation Statistics [II-4] regarding commercial airlines at Denver 

International Airport in 2001 was used to determine the appropriate engine types for aircraft selected 

from the EDMS database because the ANMS dataset did not include information regarding engine 

types. Aircraft and engine fleet mix data contained in the 2000/2001 edition of JP-Airline Fleets 

International [II-5] was also used to define EDMS aircraft/engine pairings for smaller airlines and for 

general aviation aircraft not covered in the U.S. Bureau of Transportation Statistics dataset. Table 

II-1 presents the EDMS aircraft and engine fleet mix used to model baseline year emissions.

2.1.1.2 Forecast Emissions 

Future year aircraft emissions inventories for DIA were modeled in EDMS 4.2 using aircraft 

operations data contained in the May 16, 2001 document, Aviation Activity Forecast [II-6], which is 

the current FAA-approved aviation activity forecast for the airport. For analysis years not covered in 

the forecast document, the number of aircraft operations was estimated using linear interpolation. To 

estimate activity through 2030 (APCD’s final analysis year in the CO and PM10 maintenance plan 

revisions), the level of aircraft activity was linearly extrapolated based on growth rates presented in 

the forecast. A summary of aircraft LTO cycles for the baseline year and each of the future analysis 

years is provided in Table II-3.

A summary of future-year aircraft emissions is presented in Table II-5. A detailed breakdown of 

aircraft LTO cycle data for the future analysis years is presented in Appendix A. Appendix B

2.1.2 Auxiliary Power Units 

Many large commercial aircraft are equipped with auxiliary power units (APUs). An APU is 

basically a small turbine engine that generates electricity and compressed air to operate aircraft 

instruments, lights, and ventilation when the main aircraft engines are not operational, for instance 

when aircraft are parked at the gate. APUs can also be used to provide power for starting the main 

aircraft engines. APUs burn jet fuel and hence create exhaust emissions. 

The methodology for calculating emissions from APUs is presented in Appendix E of the report Air 

Quality Procedures for Civilian Airports and Air Force Bases [II-8]. This methodology has been 

incorporated into the EDMS model. Emissions from APUs are tied to the number of LTO cycles 

performed by aircraft equipped by APUs, and the operating times of the APUs per LTO cycle. 

Default APU assignments and operating times in EDMS were utilized for this Airport Emissions 

Inventory study to provide a conservative estimate of emissions. EDMS is not capable of estimating 

PM10 emissions from APUs. Aircraft PM10 emission factors from the USEPA’s Draft 2002 National 

Emissions Inventory were also used to estimate PM10 emissions for APUs; however, the emission 

factors were scaled down to account for differences in fuel flow rates between aircraft engines and 

APUs. Default APU assignments for several aircraft are presented in Table II-6.

2.2 Airport Equipment 

For the purposes of the Airport Emissions Inventory study, airport equipment includes ground 

support equipment and City support equipment. Emissions from these two sources are described in 

the following sections. 

2.2.1 Ground Support Equipment 

Ground support equipment (GSE) includes a wide range of vehicles that are used to service aircraft 

while they are on the ground. Examples of GSE include tugs that haul baggage cars and other 

equipment, fuel trucks, catering trucks, lavatory trucks, and other service vehicles. Most GSE are 

powered by gasoline, diesel or propane. Factors that influence the level of emissions from GSE 

include airport activity levels and the load factor, horsepower, and fuel type of the GSE. GSE 

emission factors used by EDMS are derived from the USEPA’s NONROAD model. 

By default, the EDMS assigns a fleet of GSE to each aircraft type. EDMS default assignments in 

terms of GSE types and operating times were used to develop emission estimates for the baseline 

year and future analysis years. Default GSE assignments were selected to ensure that the emissions 

estimates would be conservative. Default GSE assignments for several aircraft types operating at 

DIA are presented in Table II-9, on the following page. 

2.2.1.1 Baseline Emissions 

Baseline year emissions from GSE operating at DIA are presented in Table II-10. As discussed 

above, the emissions estimate is based on EDMS default GSE assignments.

2.2.2 City Support Equipment 

City support equipment includes nonroad equipment, such as airport snow removal equipment, and 

on-road equipment, such as fleet pick-up trucks, fleet sport utility vehicles, employee shuttle busses 

and street sweepers, operated in non-public environments such as the air operations area (AOA). As 

discussed in Section 1.3, it was assumed that emissions from motor vehicle travel outside the AOA 

are accounted for in the transportation conformity models managed by DRCOG. City support 

equipment vehicles evaluated in the Airport Emissions Inventory study include diesel-powered and 

gasoline-powered vehicles. 

To calculate the emissions produced by city support equipment, it was necessary to estimate vehiclemiles traveled (VMT) by diesel-powered and gasoline-powered vehicles. The Department of 

Aviation provided information regarding gallons of gasoline and diesel fuel dispensed at DIA for city 

support equipment in 2001. Dispensed yearly fuel was assumed to increase in proportion to the 

number of annual aircraft operations. City support equipment was assumed to have an average fuel 

efficiency of twenty miles per gallon, an assumption that remained constant through all analysis 

years. VMT for each year were calculated by multiplying the gallons of fuel dispensed by twenty 

miles per gallon. 

Emissions produced by city support equipment were calculated by multiplying the VMT by fuel 

specific emission factors. Emission factors for city support equipment were developed by APCD 

using the USEPA’s MOBILE6.2 emission factor model. Emission factors developed by MOBILE6.2 

are expressed in grams per vehicle mile, therefore to calculate emissions in tons, it was necessary to 

use a conversion factor. Emission factors developed by APCD are presented in Table II-12.

2.3 Minor Point Sources 

Stationary point sources at Denver International Airport include boilers, chiller engines, emergency 

generators, cooling towers, incinerators, jet fuel storage tanks, gasoline storage tanks, and paint 

booths. These facilities are operated by the City and County of Denver and by Airport tenants. 

Baseline year emissions data for minor point sources were provided by APCD. Future year 

emissions from minor point sources were determined using growth factors provided by APCD, 

growth factors that were calculated using information in the Airport Activity forecast, or growth 

factors calculated using other information including building square footage. Growth factors used to 

estimate future year emissions for each minor point source included in the airport emissions 

inventory are described in Tables II-15 and II-16. Table II-15 includes information about minor 

point sources that emit criteria pollutants of interest for the CO and PM10 maintenance plans. Table 

II-16 lists minor point sources that emit VOC. Emissions estimates for the Central Plant boilers were 

adjusted to account for higher fuel useage during the winter months (December through February) 

using information contained in the Air Pollutant Emission Notice (APEN). Similarly, emission 

estimates for the Central Plan chiller engines were adjusted to account for lower fuel useage during 

the winter months. Seasonal variations in fuel useage or load was not factored into the emission 

estimates for other minor point sources.

2.4 Firefighting Training 

Firefighting training operations at the airport’s Aircraft Rescue and Firefighting (ARFF) training 

facility are a source of pollutant emissions. The facility allows firefighters for the airport and fire 

departments from across the Denver metropolitan area to train in a live-fire environment. Emissions 

from firefighting training operations vary based on the quantity of the fuel burned in the training fires 

and the type of fuel burned. Information about firefighting training operations at DIA including 

annual gallons of fuel burned and type of fuel burned was obtained through conversations with ARFF 

personnel [II-9]. Information regarding quantities of fuel burned and type of fuel were input into 

EDMS to estimate annual emissions from firefighting activities. Emissions from firefighting training 

operations are summarized below.

2.4.2 Forecast Emissions 

Emissions from firefighting training operations were assumed to grow over time as the number of 

aircraft operations performed at DIA increases. Emissions from firefighting training operations were 

assumed to remain constant after 2013 because the ARFF is expected to reach operational capacity in 

2013. Emissions from firefighting operations for the future analysis years are presented in Table II20.

2.5 Unpaved Roads 

Vehicle travel on unpaved roads can be a source of fugitive dust (PM10) emissions. PM10 emissions 

associated with vehicle travel on unpaved roads were calculated using an empirical formula from 

AP-42, Section 13.2.2 [II-10]. Emissions from unpaved roads are a function of the distance traveled 

on the unpaved road, the weight of the vehicle traveling on the road, and the dust content of the 

unpaved road. Vehicles traveling on unpaved roads were assumed to be either light-duty trucks or 

sport utility vehicles (SUVs). The calculation of the emission factor used in the unpaved roads 

analysis is described in Appendix D. 

Unpaved roads within the air operations area (AOA) were evaluated in the Airport Emissions 

Inventory since the APCD has already estimated emissions for unpaved roads that are publicly 

accessible (e.g., unpaved county roads). Trips made by the Denver Police Department (DPD) and a 

private security contractor were the only trips considered in the analysis. Information provided by 

the Department of Aviation, including the Airport Layout Plan, was used to determine the route 

traveled by the DPD and the private security contractor on unpaved roads and the average trip length. 

The average trip length was determined to be 24.1 miles. Additional information regarding the route 

is presented in Appendix D. 

The number of daily trips on unpaved roads performed by the DPD and the private security 

contractor were determined through conversations with DIA security personnel [II-11]. During each 

of 3 daily shifts, DPD makes 2 trips and the private security contractor makes 4 trips. The DPD 

therefore makes 6 daily trips and the private security contractor makes 12 daily. Total annual VMT 

on unpaved roads were calculated based on the number of daily trips and the trip length. It was 

assumed that changes to the airport layout in the future would not significantly change the length of 

the trip or number of trips, thus VMT was assumed to remain constant. Estimates of PM10 emissions 

associated with travel on unpaved roads are presented in Table II-21.

Section III: Construction Emissions

III. Construction Emissions 

3.1 Overview 

Construction activity at DIA is a source of pollutant emissions. The level of construction-related 

emissions at DIA varies year by year according to the number of construction projects that are 

ongoing at any one time, the size and scale of the construction projects, and the type of construction 

activity (e.g., land clearing, concrete paving, building demolition). To ensure that the Airport 

Emissions Inventory did not understate construction-related emissions at DIA, Department of 

Aviation staff defined a “worst year” construction scenario using historical records and information 

regarding capital improvement projects that have been proposed for implementation in the next 

twenty-five years. The “worst year” construction scenario was developed based on the assumption 

that construction activity for all of the potential construction projects would occur during a single 

construction season. This assumption is reasonable because airports often implement significant 

infrastructure expansions over a short time frame, following a comprehensive effort to complete 

planning and environmental analyses and obtain funding. Furthermore, it was assumed that the same 

construction emissions estimate would apply to each of the CO and PM10 maintenance plan analysis 

years (i.e., DIA construction emissions are the same for every year presented in this Airport 

Emissions Inventory study). This was done because the specific year that a worst case construction 

would occur is currently unknown. 

Table III-1 provides a summary of potential airport capital improvement projects to be constructed 

at DIA during a worst case year in the next twenty-five years. Construction emissions estimates for 

certain projects listed in Table III-1 have been prepared in support of previous general conformity 

evaluations therefore, where appropriate, these estimates were used to develop the “worst year” 

construction emissions estimate. New construction emissions estimates were prepared for the 

“Passenger Concourse” and “Terminal Module” projects because existing data were not available for 

these types of projects. Additional information regarding emissions associated with the projects 

listed in Table III-1 is presented in Appendix E. 

The combined emissions from all potential construction projects are presented in Table III-2. Based 

on a request from APCD, the Department of Aviation conducted additional analysis surrounding 

tailpipe emissions from construction equipment and the introduction of low-sulfur diesel and ultralow sulfur diesel fuel in the future. Table III-3 presents estimates of construction equipment 

emissions for each of the SIP analysis years that reflect the use of low-sulfur and ultra-low sulfur 

diesel fuel by airport construction equipment. Information contained in the USEPA memorandum 

Diesel Fuel Sulfur Inputs for the Draft NONROAD2004 Model Used in the 2004 Nonroad Diesel 

Engine Final Rule [III-1] was used to determine future-year SOx emissions for construction 

equipment. 

Appendix F presents a detailed discussion of the construction emissions analysis conducted for the 

“Passenger Concourse” and “Terminal Module” projects. Sources of information used to develop the 

emissions estimates for the “Passenger Concourse” and “Terminal Module” projects included: 

• Section 13.2.3 “Heavy Construction Operations” of AP-42. [III-2]

• Section 11.9 “Western Surface Coal Mining” of AP-42. [III-3]

• Section 11.12 “Concrete Batching” of AP-42 [III-4]

Appendix C. Minor Point Source Emissions 

This Appendix provides Baseline year and future year emissions data for minor point sources at 

Denver International Airport. The data provided herein was compiled from various sources 

including databases maintained by the Air Pollution Control Division (APCD) and information 

maintained by the City and County of Denver Department of Aviation. As discussed in Section 2.3, 

a variety of statistics from the Airport’s activity forecast and information provided by the APCD and 

the City and County of Denver formed the basis for growth factors used in estimation of future-year 

emissions from minor point sources. Table C-1 presents data regarding aircraft operations, domestic 

enplanements, international enplanements, and total enplanements at Denver International Airport for 

each of the SIP analysis years. Table C-2 provides a summary of emissions from non-VOC emitting 

minor point sources considered in the Airport Emissions Inventory. Table C-3 contains information 

about minor point sources that emit VOC.

Appendix D: Unpaved Road Emissions 

D-1

Appendix D. Unpaved Road Emissions 

This appendix provides additional information regarding the development of the estimate of PM10

emissions produced by vehicle travel on unpaved roads. PM10 emissions associated with vehicle 

travel on unpaved roads were calculated using an empirical formula from AP-42, Section 13.2.2. 

This equation is specific to vehicles traveling on unpaved surfaces at industrial sites (no public access 

to roads). The equation is shown below in Equation D-1. 

Equation D-1 

Unpaved Surfaces at Industrial Sites 

E = k • (s/12)a •

 (W/3)b

 

where:

E = size-specific emission factor (lb/VMT)

k = empirical constant (2.6)

s = surface material silt content (8.5 %)

a = empirical constant (0.9)

W = mean vehicle weight (tons)

b = empirical constant (0.45) 

 Source: U.S. Environmental Protection Agency. Compilation of Air Pollutant Emission Factors AP-42, Fifth Edition, Volume I: 

Stationary Point and Area Sources, Section 13.2.2 “Unpaved Roads”. December 2003. 

Prepared by: Ricondo & Associates, Inc. 

For these emissions calculations, the variable W was assumed to equal 5,750 pounds (2.875 tons). 

This assumption was based on manufacturer specified gross vehicle weight for a sample of light-duty 

trucks and SUVs. Empirical values for the variables k, a, and b were developed from tests of traffic 

on unpaved surfaces. The value for the variable s was obtained from samples of the dirt found on the 

unpaved surfaces. 

The route traveled on unpaved roads was determined by Burlestone, Inc. and the Department of 

Aviation based on a review of the Airport Layout Plan. The route follows the path shown below: 

Gate P42 Æ 70th Avenue Æ Hardwrick Street Æ 98th Avenue Æ Uriah Street Æ

101st Avenue Æ 99th Avenue Æ Newbern Street Æ 114th Avenue Æ Grandbay Street 

Æ west, then south to 88th Avenue Æ south to 81st Avenue Æ 79th Avenue Æ

Newbern Street. 

Portions of this route may be disconnected due to paved stretches of roadway. Emissions from paved 

roadways are not included in the emissions estimates presented in Section 2.5, “Unpaved Roads.”

F-1

Appendix F. Construction Emissions Terminal and Concourse 

Construction emissions estimates for a proposed Terminal Module and a Passenger Concourse were 

developed by Ricondo & Associates in association with Burlstone, Inc. and are documented in this 

appendix. Construction of both the Terminal Module and the Passenger Concourse is expected to 

occur over a period of two years. Emissions for each construction year of the projects were 

calculated separately, and for each project, the year with the highest emissions was identified. The 

emissions produced during this year were included in the total construction emissions estimate 

presented in Section III and Appendix D. 

F.1 Land Development 

Earth moving activities during construction and wind erosion are sources of PM10 emissions. PM10

emissions caused by earth moving and wind erosion were calculated using the methodologies 

outlined in Section 13.2.3 “Heavy Construction Operations” of AP-42. Land development emissions 

associated with the Terminal Module and the Passenger Concourse are presented in Tables F-1 and 

F-2, respectively. Assumptions used in the estimation of land development emissions are described 

below.

Appendix F: Construction Emissions Terminal & Concourse 

F-2

F.1.1 Earth Moving Emissions 

The excavation, grading, and general disturbance of soil on a construction site results in PM10

emissions. Emission factors for earth moving activity are found in Section 13.2.3 “Heavy 

Construction Operations” of AP-42. According to the Colorado Department of Public Health and 

Environment’s Air Pollution Control Division Adequate watering of the construction site as a control 

efficiency would be expected to reduce PM10 emissions by 50%. For the purposes of the Denver 

International Airport Emissions Inventory study, no control efficiency was assumed. 

F.1.2 Wind Erosion Emissions 

Dirt piles, areas of bare soils, and newly paved portions of a construction site can be source of 

windblown PM10. Emission factors for wind erosion were derived from Section 11.9 “Western 

Surface Coal Mining” of AP-42. No control efficiencies were assumed for the Airport Emissions 

Inventory study; however the State of Colorado typically assigns control factors for techniques that 

reduce wind erosion emissions including watering, soil stabilizers, and revegetation among others. 

F.2 Concrete Batching 

Concrete is composed of water, cement, sand and coarse aggregate. During the process of 

manufacturing concrete (concrete batching) these raw materials can be the source of PM10 emissions. 

Fugitive sources of PM10 emissions during concrete batching include the transfer of sand and 

aggregate, truck loading, mixer loading, and wind erosion from sand and aggregate storage piles. 

The process of estimating particulate emissions associated with concrete batch plant operations is 

described in Section 11.12 “Concrete Batching” of AP-42. Concrete batch plant emissions 

(excluding wind erosion emissions) were calculated by multiplying the number of cubic yards of 

concrete necessary for each construction project by a particulate emission factor. PM10 emission 

factors per cubic yard of concrete for an average batch formulation at a typical concrete batch plant 

using the central mix method are presented in Table 11.12-4 “Plant Wide Emission Factors Per Yard 

of Central Mix Concrete” in Section 11.12 of AP-42. PM10 emissions associated with wind erosion 

from sand and aggregate storage piles were calculated using methodologies presented in Section 11.9 

“Western Surface Coal Mining” of AP-42 because wind erosion factors are not included in Section 

11.12. 

An estimate of concrete batch plant emissions for the Terminal Module and Passenger Concourse are 

presented in Table F-3 and Table F-4, respectively.

F.3 Construction Equipment 

Construction equipment emissions estimates are generally developed using two basic methodologies 

(Nonroad and Onroad) depending on the type of construction equipment. Nonroad construction 

equipment (e.g., bulldozers, backhoes, front end loaders, etc.) are generally operated off road and on 

the construction site. Onroad construction equipment (e.g., semi-trucks for material hauling), in 

contrast can be operated on public roads. Nonroad estimation methods which are described in the 

USEPA report, Nonroad Engine and Vehicle Emission Study—Report were used for the airport 

emissions inventory study since most of the construction activities would require heavy duty 

construction equipment. 

Emissions from diesel-powered engines are regulated under 40 CFR, Part 89.112. Emission factors 

associated with diesel engines vary by engine year and horsepower according to Tier 1, Tier 2 Tier 3, 

and Tier 4 standards as defined in Table 1 of the USEPA Report NR-009c, Exhaust and Crankcase 

Emission Factors for Nonroad Engine Modeling – Compression-Ignition. These factors were used 

with data and methodologies described in the USEPA report, Nonroad Engine and Vehicle Emission 

Study—Report to estimate diesel equipment emissions for each construction year. Emissions were 

calculated based on the type of fuel, engine horsepower, equipment use in hours, and the average age 

of the construction equipment. 

The USEPA recommended technique for calculating emissions from nonroad construction equipment 

is presented in Equation F-1.

Equation F-1 

Nonroad Construction Equipment Emissions Calculation Equation 

 Mi = (N)(HRS)(HP)(LF/100)(EFi) 

 

 where: 

 

Mi = mass of emissions of ith pollutants during inventory period

N = source population (units)

HRS = annual hours of use

HP = average rated horsepower

LF = typical load factor

EFi = average emissions of ith pollutant per unit of use (e.g., pounds per horsepower-

 hour)

The fleet age of the diesel construction equipment used for the proposed project was estimated to be 

an eight (8) year spread – for the 2005 construction year it was assumed that the oldest piece of 

equipment was manufactured in 1998. Through the use of the vehicle age spread a weighted average 

of Tier 1 and Tier 2 emissions standards were developed for each equipment horsepower range. This 

methodology is the most representative process of calculating pollutant emissions for nonroad 

construction equipment equipped with diesel engines. 

Hourly estimates of construction equipment utilization for the Terminal Module and Passenger 

Concourse were prepared by Burlstone, Inc. A summary of the major assumptions used to develop 

construction equipment utilization estimates are provided below: 

• The projects would occur at accelerated schedules and construction of the Passenger 

Concourse and the Terminal Module would each be completed within two years. 

• In general, “light equipment” (i.e., pavement cutters, skid steer loaders, hand compactors, 

etc.) have been excluded from the equipment estimates. 

• Equipment types, load capacity rates, and horsepower information are based on 

information in the Caterpillar Performance Handbook, Edition 30. 

• The dump location for excavated materials (soil, concrete, etc.) is located in close 

proximity to the site, and the round trip time for loading is approximately 30 minutes. 

• The Passenger Concourse will be constructed to match the footprint of an existing 

concourse. 

• All caissons are 36” diameter and 30 feet in depth. 

• All concrete pavement is 17” thick. 

• A 25% reduction in production rates was applied to all phases of construction as a 

contingency. 

• Pickup truck time for a site superintendent has been added to each phase of work. 

• Detention systems for storm runoff have been excluded. 

• Six bridges would be constructed to accommodate the terminal expansion. Existing 

bridges would be removed.

• The total length for each of the AGTS loops (east and west) is 13,617 feet of which 4,243 

is elevated. 

• The relocated glycol ponds and AGTS maintenance facility are the same size as the 

existing facilities. 

Estimates of construction equipment emissions for the Terminal Module are presented in Tables F-5 

and F-6. Estimates of construction equipment emissions for the Passenger Concourse are presented

Appendix G: Grids for Regional Air Quality Modeling 

The State of Colorado Air Pollution Control Division (APCD) has divided the Denver metropolitan 

region into a finite number of grid cells for the purposes of regional air quality modeling/air 

dispersion analyses. The APCD recently developed two grid cell maps for the area covering Denver 

International Airport: one for particulate matter (PM10) and the other for carbon monoxide (CO). The 

grid cell maps are presented on Exhibits G-1 and G-2 and were provided to the City and County of 

Denver Department of Aviation for use in the Airport Emissions Inventory study. 

This memorandum presents recommendations regarding the apportionment of airport-related 

emissions to APCD’s grid cells in support of future regional air quality modeling to be conducted by 

APCD. Tables G-1 and G-2, respectively, present a list of PM10 and CO grid cells where there 

could be emissions (either now or in the future) from airport-related sources of emissions. The tables 

present grid cell information for each emission source described in the Executive Summary of the 

Airport Emissions Inventory. It is assumed that APCD will evenly distribute the annual inventory of 

PM10 and CO emissions over all grid cells relevant to a particular source category as identified in 

Tables G-1 and G-2.
