1.0 Executive Summary

The purpose of this study is to develop a set of average summer weekday (tons per day) emission inventories (EI) for Texas airport activities based on a 2011 base year.

Eastern Research Group (ERG) developed emissions inventories for criteria and hazardous air pollutants (HAPs). The inventories will be used to support the State Implementation Plan (SIP) and other airport-related inquiries.

The emissions associated with airport activities are attributed to the following sources with associated source classification codes (SCC):

Commercial aviation (SCC: 2275020000) Air taxis

Piston driven (SCC: 2275060011) Turbine driven (SCC: 2275060012)

General aviation Piston driven (SCC: 2275050011) Turbine driven (SCC: 2275050012)

Military (SCC: 2275001000) Auxiliary Power Units (SCC: 2275070000) Ground Support Equipment

Compressed natural gas (CNG)-fueled (SCC: 2268008005) Diesel-fueled (SCC: 2270008005) Gasoline-fueled (SCC: 2265008005) Liquefied petroleum gas (LPG)-fueled (SCC: 2267008005).

To estimate emissions from these sources, ERG used the original activity data obtained for Work Order 582-11-99776-FY12-09 for calendar year 2011 which included local airport data and publicly available activity data. Additionally, ERG, via TCEQ, also obtained local aircraft specific data from the DFW area from the North Central Texas Council of Governments (NCTCOG) during the previous work order as well. Two approaches were used to estimate emissions from the compiled activity data. For activity data that included aircraft-specific data, ERG used the Federal Aviation Administration’s (FAA) Aviation Environmental Design Tool (AEDT) to estimate emissions. If such detailed data were not available, ERG applied a more general approach for different aircraft types (i.e., air taxis, general aviation, and military aircraft) using the United States Environmental Protection Agency’s (EPA) available generic emission estimating procedures for the National Emission Inventory (NEI). Additional information on methodology are included later in the document.

In 2011, general aviation aircraft outfitted with piston engines account for 27.9% of the total aircraft activities. This included the data obtained from DFW. General aviation aircraft outfitted with jet engines, commercial aircraft, air taxi aircraft outfitted with

1-2

piston engines, military aircraft, and air taxi aircraft outfitted with jet engines, and account for 23.9%, 16.5%, 14.6%, 8.6%, and 8.4% of the total aircraft activities, respectively. Harris County and Tarrant County had the highest aircraft activity, accounting for 14.8% and 11.4% respectively of all Texas activity.

2.0 Introduction

2.1 Purpose and Objectives

The purpose of this study is to develop a set of area-specific average summer weekday (tons per day) EIs for all airport sources including aircraft, Auxiliary Power Units (APU), and Ground Support Equipment (GSE) to support airport related inquires.

To develop the comprehensive inventories for the aircraft source category, ERG conducted the following tasks:

Recompile previously collected 2011 activity data from local airports and publicly available data sources.

Calculate 2011 emission estimates using FAA’s AEDT 2d and generic emission factors.

Project 2011 activity and emission estimates to 2017, 2018, 2020, and 2021, using the FAA’s Terminal Area Forecast (TAF) dataset.

Calculate average summer weekday emissions. Summarize activity and emissions data.

It should be noted that the engine-specific factors used in the AEDT model were derived from testing data used to certify the engines and account for U.S. and international emissions standards. The inventories will be used to support the airport-related inquires.

Section 3.0 of this report identifies the national and local activity data sources included in this study. This section describes how ERG pulled from each activity data source to compile the 2011 activity dataset. This section also documents any assumptions or adjustments that were made to each data source to facilitate the development of the activity dataset.

Section 4.0 summarizes the emissions estimation methodology and also summarizes the activity and emission projection procedures for 2011. This section includes summary emissions tables on a county-level basis by SCC for criteria pollutants.

The criteria and HAP emissions associated with airport activities are included in the Excel Files submitted with this report for 2011.

2.2 Background

This report covers airport activities as point sources in the emission calculation but are summarized as nonroad sources. The AEDT model treats airports as point/facilities. Once the emissions are estimated the data are aggregated to the county level as nonroad sources. The aircraft source category includes all aircraft types used for public, private,

2-2

and military purposes. The emissions associated with airport activities are attributed to the following sources with associated SCC:

Commercial aviation (SCC: 2275020000) Air taxis

Piston driven (SCC: 2275060011) Turbine driven (SCC: 2275060012)

General aviation Piston driven (SCC: 2275050011) Turbine driven (SCC: 2275050012)

Military (SCC: 2275001000) Auxiliary Power Units (SCC: 2275070000) Ground Support Equipment

Compressed natural gas (CNG)-fueled (SCC: 2268008005) Diesel-fueled (SCC: 2270008005) Gasoline-fueled (SCC: 2265008005) Liquefied petroleum gas (LPG)-fueled (SCC: 2267008005).

Commercial aircraft transport passengers, freight, or both and tend to be larger aircraft that are driven with jet engines. Air taxis (AT), which are also considered to be commercial aircraft, are usually smaller aircraft (less than 60 passengers) that operate on a limited basis compared to larger commercial aircraft that carry between 60 and 800 passengers. General aviation (GA) includes most other aircraft used for recreational flying and personal transportation. Aircraft that support business travel, usually on an unscheduled basis, are included in the GA category.

Aircraft tend to emit significant amounts of air pollutants. The national AT and GA fleet includes both jet and propeller-driven aircraft. Most of the AT and GA fleet are comprised of piston- (or propeller-) driven aircraft, though these aircraft types also include smaller business jets and turboprops. The piston-driven aircraft tend to have higher VOC emissions and lower NOx emissions than larger turbine-powered aircraft. According to the EPA, propeller-driven aircraft and turbine-driven aircraft account for 72.1% and 27.9%, respectively, of all GA emissions. Propeller-driven aircraft and turbine-driven aircraft account for 21.8% and 78.2%, respectively, of all AT emissions1. EPA has used this estimate as a national-scale default value in recently published studies investigating lead emissions from aviation sources.

Military aircraft comprise a wide range of aircraft types such as training aircraft, fighter jets, helicopters, and jet- and propeller-driven cargo planes of varying sizes. Because of a lack of information concerning the make-up of the military aircraft fleet, EPA has assumed that most military aircraft are jet-powered.

Aircraft emissions are associated with an aircraft’s landing and takeoff (LTO) cycle. The cycle begins when the aircraft approaches the airport on its descent from cruising

2-3

altitude, then lands and taxis to the gate, where it idles during passenger deplaning. The cycle continues as the aircraft idles during passenger boarding, taxis back onto the runway, takes off, and ascends (or climbs out) to cruising altitude. Figure 2-1 illustrates the six specific operating modes in an LTO cycle:

Approach Taxi/idle-in Taxi/idle-out Idling Takeoff Climb out.

The LTO cycle provides a basis for calculating aircraft emissions associated with airports. During each mode of operation, an aircraft engine operates at a specific power setting and fuel consumption rate for a given aircraft make and model. Emissions for one complete cycle are calculated by multiplying emission factors for each operating mode for each specific aircraft engine and the typical period of time the aircraft is operating.

3.0 Data Sources of Texas Airport Activities Inventoried

ERG used detailed activity data obtained for work order 582-11-99776-FY12-09 for calendar year 2011 as well as data from NCTCOG to develop a base year inventory for Texas airports. The DFW data from NCTCOG was not part of the previous work order but was obtained during the work order so it could be incorporated in the inventory to a comprehensive inventory for the entire state of Texas. The original 2011 activity data ERG compiled, including DFW area data from NCTCOG, is presented in Appendix A. Below is a brief discussion of the work done in the previous work order to obtain the activity data.

3.1 National Data Sources of Texas Airport Activities

To estimate emissions from aircraft operating in Texas, ERG used the activity data compiled by EPA intended for use in the 2011 National Emissions Inventory (NEI). Activity data were compiled from the following sources:

Bureau of Transportation Statistics (BTS) T-100 segment dataset,2 FAA Terminal Area Forecast (TAF) dataset/Air Traffic Activity System (ATADS)

and 3, 4 FAA Airport Master Record (5010) dataset.5

The compiled data are adjusted for duplicates associated with the three datasets and supplemented with local data discussed further in Section 3.1.4. This section discusses each data source investigated for this project summarizing the publicly available data and noting any limitations or data gaps.

3.1.1 T-100 Dataset

The T-100 data is an activity dataset that includes information provided by domestic and international commercial air carriers. During the time period of this study, only January through August activity data were available for 2011. In order to obtain the missing months from the 2011 activity dataset, data from September through December for 2010 were adjusted to reflect 2011 data using scale factors developed from the TAF dataset. This dataset had the most specific data of the three datasets. The T-100 data included airport, aircraft make and model, and LTO cycle data. The engine information was incorporated into the dataset from the FAA’s AEDT default engine list. The aircraft categories were assigned to each aircraft with the assumption that T-100 only includes commercial aircraft and air taxis. Aircraft were assigned the AT aircraft category, if the number of seats on the aircraft were less than or equal to 60, otherwise the aircraft was assigned to the commercial air carrier (AC) category Appendix A summarizes the T-100 data used for this study.

3.1.2 TAF Dataset

The TAF dataset is an FAA dataset derived from a variety of sources such as reported traffic at FAA towered facilities, data reported directly by airports and FAA derived estimates from historical information. This dataset includes airport, aircraft categories, and operations data.

The aircraft categories included AC, AT, military (MIL), and GA. It can be assumed that 72.1% of all GA activity are powered by propeller-driven aircraft and 27.9% are jet (or turbine) driven; and 21.8% of all AT activity are powered by propeller-driven aircraft and 78.2% are jet (or turbine) driven. The aircraft categories from AT and GA were broken out into piston and jet engines. This breakout is important because piston engines have different emission factors than jet engines.

For consistency between the other two datasets, the TAF operations data were converted into LTO cycles. There was overlap between the TAF dataset and T-100 dataset. The T-100 activity had a higher priority than the TAF dataset because it had greater detail; consequently, the duplicate data were removed from the TAF dataset.

3.1.3 5010 Dataset

The 5010 dataset was EPA compiled data from the FAA’s airport 5010 master plan data and estimated activity levels based on statistical techniques described in greater detail in the EPA aviation lead report from December 20106. The 5010 data were provided to the states via the EPA’s National Emissions Inventory (NEI). This data includes airport, aircraft categories, and LTO cycle data.

The aircraft categories include AC, AT, MIL, and GA. The aircraft categories provided by the EPA in the 5010 dataset were AT and GA broken out into piston and jet engines as they tend to include some of the smallest airports and landing strips.

3.2 Contacting Airports

The medium to large airports were contacted in order to provide 2011 activity data and to identify and characterize control strategies used or planned at each airport. The medium to large airports identified for contacting were based on estimated activity levels. Thirty-five candidate airports were identified that had 19,000 LTO cycles or more in the previous 2008 inventory. These candidate airports accounted for 32% of the activity in Texas, not including airports included in the DFW Metropolitan Planning Organizations’ planning area. DFW area airports provided data separately through NCTCOG. ERG did not need to contact NCTCOG. Prior to the project, NCTCOG had already agreed to provide TCEQ their activity and emissions data.

3-3

Once the medium to large candidate airports were identified, each airport was contacted by telephone and asked to provide the following.

2011 landing & take-off data for the airport, Average taxi-in and taxi-out times for the airport, and List emission control strategies (i.e. gate electrification, auxiliary power units,

etc.) for 2011and the expected emission reduction.

Of the airports contacted 40% of the airports submitted 2011 operations data, 26% submitted taxi time estimates, and 11% provided control strategies. ERG located 2011 operations data for 9% of the airports by conducting internet searches at each airport website.

3.2.1 Summary of Local Data Received

As noted in the previous section, ERG collected local data from 49% of the airports contacted (40% of the airports submitted data and ERG located data for an additional 9% of the airports by conducting internet searches). In addition, 26% of the airports submitted taxi time estimates and 11% provided emission control strategies.

The local data was available in different formats depending on how each airport recorded airport activity. The 2011 operations data were submitted as annual totals, annual totals by generic aircraft type categories, or annual totals by specific aircraft make and model.

For additional details on local data, please refer to Development of Statewide Annual Emissions Inventory and Activity Data for Airports, Final Report TCEQ Contract No. 582-11-99776, Work Order No. 582-11-99776-FY12-09.

4.0 Summary of 2011 Emissions Development

4.1 Emission Estimation Methodology

To develop the most accurate aircraft emission inventory possible, ERG took two different approaches. If aircraft-specific data were available, ERG used the FAA’s AEDT model in conjunction with detailed aircraft activity data from T-100 (see Appendix A for T-100 data). If such detailed data were not available, then ERG applied a more general approach for different aircraft types (i.e., air taxis, general aviation, and military aircraft) using available generic emission estimating procedures. Using these two complementary approaches provides the most accurate emission estimates for the larger commercial jets, which tend to be the most significant aircraft emission source, while still providing estimates for smaller aircraft.

4.1.1 Aircraft Specific Estimation Methodology (AEDT)

AEDT was used for the aircraft-specific activity data. To pull the data into AEDT, EDMS legacy files were employed. The aircraft-specific activity data were formatted and imported into EDMS. Once the data were in EDMS and quality checks implemented, the EDMS study was exported into an EDMS legacy text file.

Through extensive EDMS legacy file testing, edits were made to the file to successfully import into AEDT. Empty International Civil Aviation Organization (ICAO) airport codes were populated with FAA airport codes to prevent the appearance of duplicates during the EDMS to ASIF file conversion. ASIF is an XML file format created by FAA specific to AEDT for importation. Through this conversion, a unique airport code is required.

Additional changes to the EDMS legacy file included updating two outdated aircraft/engine combinations and updating the fuel type for one Ground Support Equipment (GSE) code.

ERJ140/AE3A13 and B757-3/PW2043 required engine code updates: PW2043 to XPW204, and AE3A13 to 6AL011.

The GSE code “21”, Taylor Dunn – Cart, fuel type was updated from D (diesel) to G (gasoline).

Once the EDMS legacy file was successfully imported into AEDT, additional tweaks were required. These updates included:

Dallas Love Field/Lockheed P-3 Orion updated to Lockheed P-3 Orion ANP:P3A (Lockheed P-3 Orion did not have a flight path)

Engine 1PW003 updated to 1PW002. (1PW003 and an index of -1)

4-2

After confirming all operations had been successfully imported into AEDT, the emissions inventory was run and exported into two .csv files, one file for aircraft operations and one file for criteria emissions. Two files were exported due to how the AEDT software was designed. These files were exported and formatted for the fight path below mixing height, APU operations, and GSE operations. The emissions were converted from grams to short tons, and additional IDs were added to each file, including state facility identifier, SCC codes, and aircraft engine type codes. The emissions data were exported as emission factors; these emission factor data were multiplied by the operations to estimate total emissions by aircraft type and airport.

4.1.2 Generic Emissions Estimating Procedures

AEDT can provide emission estimates if the aircraft make and model are known. Often this is not the case for air taxis, general aviation, and military aircraft activity in the TAF and 5010 datasets. For smaller airports in Texas without aircraft specific activity from the T100, ERG used the generic approach that relies upon representative criteria emission factors and HAP Speciation Profiles provided by EPA7,8,9, using the following equation:

Eixj = LTOi × FRx × EFij Where:

Eixj = Emission estimate for aircraft type i equipped with engine type x and pollutant j (lbs/year)

LTOi = Annual count of LTO cycles for aircraft type i FRx = Fraction of LTOs equipped with engine type x EFij = Generic emission factor for aircraft type i equipped with engine type x

and pollutant j (lbs/LTO) i = Aircraft type (i.e., air taxi, general aviation, and military) x = Engine type (i.e., jet or turboprop, and piston engine) j = Criteria pollutant j

Critical to the calculation is the application of representative emission factors that account for the different aircraft in the national fleet. Table 4-1 lists the generic emission factors for Criteria Pollutants by aircraft type.

As discussed above, when the GA and AT breakout is unknown, EPA has assumed that 72.1% of all GA activity are powered by propeller-driven aircraft and 27.9% are jet- (or turbine) driven; and 21.8% of all AT activity are powered by propeller-driven aircraft and 78.2% are jet- (or turbine) driven. The 5010 data had the piston and jet engines already disaggregated.

4.1.3 Controlled and Uncontrolled 2011 Base Year Inventory

This project required controlled and uncontrolled baseline 2011 inventories. The updated inventory served as the uncontrolled 2011 emissions inventory, and the controlled 2011 baseline inventory was adjusted to account for APU control strategies.

APU emissions can be reduced by using electricity and pretreated ventilation air from the terminals. Where local data indicated that such activities are part of the facilities emission reduction strategy, ERG reduced APU emissions by 90% based on EPA guidance for the following airports:

George Bush Intercontinental (IAH) Austin-Bergstrom Intl. (AUS) William P Hobby (HOU) San Antonio Intl. (SAT) El Paso Intl (ELP) Lubbock Preston Smith Intl. (LBB) Valley Intl. (HRL).

No control information were obtained from NCTCOG.

4.1.4 Calculating Summer Daily Emissions

Summer weekday emissions for the analysis years 2011 were developed by dividing annual emissions by 365. T-100 data were analyzed to assess if there were any significant seasonality that would warrant a different factor. There was no significant difference. For consistency with past inventories the 1/365 factor (0.00274) was used.

4.2 Summary of Texas Airport Emissions

The results of implementing the emission estimation methodology for the years 2011 are presented in Table 4-2 through Table 4-6. It is important to note that emissions may seem abnormally high for Wichita County compared to previous inventories, but emissions are correct. This is due to the higher than normal military activity from Sheppard Air Force Base (SPS) in Wichita County and the fact that the generic military emission factors were updated by the EPA recently. Emissions for all counties are in Appendix C and D. Figure 4-1 summarizes the LTOs by county using a color gradient. Quality assurance checks implemented for this project are summarized in Appendix E.

Background: The purpose of this project was to develop a set of Statewide and Area-specific emissions inventories (EI) and activity data for all airport sources including aircraft, Auxiliary Power Units (APU), and Ground Support Equipment (GSE). These Els are needed to fulfill the Federal Air Emissions Reporting Requirements (AERR) and support State Implementation Plan (SIP) development. For this project, ERG developed the annual (tons per year) and average summer weekday (tons per day) emissions inventory estimates of Criteria Air Pollutants (CAP), CAP precursors, and Hazardous Air Pollutants (HAP) using the Federal Aviation Agency (FAA) Aviation Environmental Design Tool (AEDT) model. The overall objective of this project was to provide the aircraft mobile sources 2017 evaluation year activity and annual emissions inventory estimates required for the State of Texas for inclusion in the EPA’s 2017 NEI and emissions inventories for SIP development. The previous trend inventory for 2017 was used for every Texas county including estimates for controlled and uncontrolled emissions in both annual (tons per year) and average weekday (tons per day) emissions. The secondary purpose of this project was to develop area-specific emissions inventories necessary to support both an attainment demonstration and a rate of further progress (RFP) analysis for the Houston-Galveston-Brazoria (HGB) eight-county and the Dallas-Fort Worth (DFW) ten-county non-attainment areas to develop the SIP revision(s) for the 2008 eight-hour ozone National Ambient Air Quality Standard (NAAQS). These inventories were based off previously collected data for 2011 and the 2020 inventory was developed by projecting data from the 2017 activity data.

Project/Task Description:

To meet the project objectives, the following tasks were completed:

Provided an emissions inventory development plan Recompiled the 2011 calendar year data from Work Order 582-11-99776-FY12- 09 Developed Summer weekday emissions for 2017, 2018, 2020, and 2021 for the HGB

Eight-County and the DFW Ten-County areas using the previous 2011 data Developed a revised statewide 2011 EI and provided the AEDT files Collected new 2017 national data and local data Developed 2017 statewide inventory and formatted the data into XML for TexAER

and EPA EIS Projected the 2017 statewide inventory to 2020 and provided the 2017 AEDT files Provided the final report

The project included producing XML files and Excel summary files which were shared with the TCEQ Work Assignment Manager and used in our quality checks. Quality Objectives and Criteria: ERG provided the TCEQ with comprehensive and accurate emission inventories based on the FAA’s latest emission estimating model. Typically, the quality of such inventories was measured by the degree to which local rather than default data were used in their development. ERG documented all the airports from which we solicited data including documentation of repeated calls and emails. Only when there were data gaps in the local data did ERG use national FAA data to gap fill. The FAA data used was obtained from the T-100 dataset that provides aircraft make and model specific data for the 49 airports in Texas that provide commercial air services from a regulated airline. These T-100 data were supplemented with FAA Terminal Area Facility (TAF) data and the FAA’s airport Master Plan data (5010) to quantify aircraft activities in the remaining Texas airports. Note that the 5010 and TAF datasets provide activity data in terms of generic aircraft types. Adjustments were made to the generic LTO counts to avoid double counting with the local data and the T-100 aircraft specific data. The resulting TCEQ airport inventory includes locally provided data, T-100 aircraft specific data, and TAF/5010 generic data to ensure that all Texas airports have representative activity data. The 2011, 2017, and 2020 inventories developed for this project were compared to previous inventory efforts. The 2011 inventory was compared to the 2011 inventory created for the TCEQ’s 2011 NEI submittal (Work Order 582-11-99776-FY12- 09). The 2017 and 2020 inventories were compared to the applicable trend inventories developed from the 2014 inventory submitted to the EPA for the NEI. These comparisons were implemented at the state level to evaluate whether the overall state trend was reasonable; at the county level to see if there were any counties that indicated an unexpected increase or decrease in emissions; and at the airport and aircraft level to identify outliers. When outliers were identified, ERG investigated further to ensure that the data were correct and there were no errors in data handling, in creating the input files for AEDT or for generic aircraft data, and the emission queries were evaluated to ensure they were linking the data correctly.

E-4

Under Task 4, the final emissions inventory and activity data were formatted to meet the TCEQ’s TexAER and EPA’s CERS XML requirements. Special Training/Certification: No special training or certification is required. Documents and Records: The process used to collect data and develop the inventories was documented from start to finish. All procedures and data sources used to create the inventories were presented such that the TCEQ or any third party have sufficient information to independently replicate any part of the process if needed. The process of providing interim products for each work task and obtaining TCEQ review comments enhanced the completeness and quality of the documentation in the final project report. The final report includes this document in the QA section, discussion of any problems encountered, corrective actions taken, and limitation of the data identified in the process of developing the emission inventories. B. Data Generation and Acquisition

ERG recompiled the 2011 data originally obtained from Work Order 582-11-99776-FY12- 09. ERG conducted no additional data acquisition for 2011. ERG obtained various aircraft activity data for 2017. There are two general sources of airport data. The preferred sources are from the local airports. The other data are from the publicly available national information from the FAA. ERG contacted 213 local Texas airports by telephone and email to request 2017 activity data and to identify and characterize control strategies used or planned at each airport. Of the 213 airports contacted, 26 provided data that could be used in the 2017 inventory. To develop the most accurate aircraft emission inventory possible, ERG took two approaches. First, if aircraft-specific make and model data were available, ERG used the FAA’s AEDT model in conjunction with the detailed aircraft activity data either provided by the airport or obtained from T-100. If such detailed data were not available, then ERG applied a more general approach for different aircraft types (i.e., air taxis, general aviation, and military aircraft) using available generic activity data from the local airports, or from the FAA’s TAF dataset and FAA’s 5010 dataset in conjunction with EPA emission estimating methods noted in the National Emission Inventory documentation.

a. Data Management

No hard copy data were received during the project. For this project all data obtained were electronic. Working copies of the original data files were shared with the team, such that the integrity of the original files was maintained. The original files were never checked out, and only viewed a couple of times to confirm that the data in the working files were correctly transferred.

E-5

The electronic working files were stored in a specific project directory on ERG’s network drive in Morrisville, North Carolina. The original data files were kept in a separate folder on the same network. All files on the Morrisville server are backed up daily. Only project team members were granted access to the directories where the working files were stored, such that all members of the team had access to all project data and could perform their work using these files. Once the project was completed, all project electronic files were moved into an archive directory on the network for permanent storage.

C. Assessment and Oversight

Data collection efforts were coordinated so that all ERG team members understood the project goals. Following the kickoff discussions with TCEQ staff and submittal of the work plan, the ERG Project Manager and task leads had internal team meetings to discuss and verify data collection efforts for each project task. Each team member had a clear understanding of all project objectives and deliverables and the data that will be needed to support those deliverables. This coordinated process is seen as essential to efficient and productive data collection. When data were received from airports, federal agencies or the TCEQ, the staff receiving the data put the original data files directly on the Morrisville server and sent a working copy to the appropriate staff responsible for that task. These staff members reviewed and briefly summarized the findings in the data submittal and informed the ERG project manager. The ERG project manager informed the TCEQ project manager of the data submittal noting any issues with the data based on the initial summary. Once the TCEQ project manager approved the data, ERG team members started working with the submitted data. The TCEQ project manager did not direct ERG to exclude any of the compiled data. After the aviation data had been compiled and adjustments were made to avoid double counting, the data were stored in a file format appropriate for inclusion into the AEDT. Peer reviewers knowledgeable about the source category but not directly involved in conducting day to day activities of the project reviewed all data handling methods and results of the work. ERG’s peer reviewers were included in the initial planning stages of this project to ensure the planned approaches were technically sound and that quality checks were planned for critical points in the process. This included review of AEDT input files and output files as well as the generic aircraft type calculations.

ERG peer reviewers did not find any issues with data handling for the AEDT input files nor did they have any problem reproducing the generic emission estimates using the project access database and associated queries.

All final products were reviewed by senior team members prior to submittal to the TCEQ to ensure the project procedures were properly implemented. The ERG Project Manager and task leads signed off on all deliverables to the TCEQ documenting that all quality checks were implemented and where problems were identified corrections were made in the preliminary or final dataset, and the draft or final report.

E-6

The ERG editor worked directly with task leads, making changes to the draft report to make the document clear and easy to follow. The ERG Project Manager also ensured that the final report included all recommended changes suggested by the TCEQ Project Manager.

Reports to Management: The ERG project manager reported to the TCEQ project manager on a biweekly schedule or sooner if something urgent was raised. D. Data Validation and Usability and Verification and Validation Methods

All information used to develop the emission inventories were checked and reviewed for reasonableness to the extent possible. This included checking activity data and emission factors against the reference source, such as the FAA T-100 and TAF datasets and the EPA’s Documentation for the National Emission Inventory to ensure that the values used were correct (e.g., decimal location is correct, units are converted correctly). A minimum of 10% of the data were audited by an independent reviewer not involved with the inventory development. 100 percent of all calculation queries were checked by having a second staff member replicate the result by independently applying the input data and assumptions to see if the same data were produced.

The ERG data review did not find any formatting issues with the data used for the AEDT model input file or issues with the generic emission calculations.

Activity and emissions data were reviewed by the Project Manager to ensure they were reasonable and consistent (i.e., extremely low or high values that are usually indicative of errors were flagged for further investigation). ERG highlighted NOx emissions as it is a critical pollutant for the nonattainment areas. Any data that were found to be questionable were examined in greater detail to determine what was causing the issue and what adjustments, if any, were required. If data were revised, the procedures and assumptions used were documented. The Project Manager and task leads reviewed and approve all data adjustments, as documented in this QA summary. 2011 to Previous 2011 Inventory Comparison

The 2011 inventory including the DFW and HGB SIP areas was initially analyzed at the county level to see if there were any outliers. Table E-1 summarizes the counties with an absolute difference of 1000% percent or greater from the original 2011 inventory. Because the LTO data matched between the original 2011 data from Work Order 582-11-99776-FY12- 09, and the new inventory using AEDT and new EPA generic emission factors, ERG then looked at the data at the airport level within those counties to see where the underlying sources of the differences were. These airports are summarized in Table E-2.

* Percent change greater than 1,000% a. Previous Inventory was based on the same LTO data but used EDMS and older EPA generic emission factors.

E-9

The data from Table E-2 showed that the LTO data matched, whereas the emissions were higher in the new 2011 inventory developed using AEDT. Table E-2 also compares the new generic emission factors from the EPA to the emissions factors used in the prior inventory that was developed using the FAA’s older EDMS software and the EPA’s older generic emission factors. It is recognized by the FAA that AEDT emissions differ from EDMS emissions. Factors that contribute to these differences include the use of different fuel consumption methods (AEDT data are considered more accurate as they are based on aircraft flight recorder data). Also, AEDT uses different methods to determine aircraft weight, flap and power settings. EDMS uses more generic default values for these aircraft operating perimeters (see https://aedt.faa.gov/Documents/Comparison_AEDT_Legacy_Summary.pdf). Overall, AEDT is believed to provide more accurate emissions estimates than EDMS. Based on ERG’s analysis, the AEDT model generated results consistent with the FAA’s findings that overall emissions from the resulting model outputs are typically higher than corresponding results from EDMS when analyzing aggregate emissions estimates. Comparing the two models can be very complicated, as the two models use different methodologies to account for airport factors (e.g., runway length, relative elevation, time in mode and local meteorology) and aircraft factors (e.g., aircraft rate of climbout/descent, engine specific fuel consumption, aircraft weight, engine mode operations). Table E-3 provides a simple comparison where the emissions for a BOEING 737 200 series equipped with Pratt and Whitney 1PW011 engines are normalized on a per LTO basis.1 As Table E-3 indicates, EDMS and AEDT emission estimates can differ for different airports and pollutants. Variance in the AEDT output appears reasonable when considering the variance typically associated with the EDMS output, based on ERG’s experience working with EDMS outputs.

1 This is just one example for the 737 200 series, most aircraft models have multiple engine options, and this series

has five different low-bypass turbonfan variants as part of their JT8D product line.

Additionally, ERG looked at the data at the airport and SCC level, summarized in Table E-4. This table clearly showed that the large difference (14,035% increase) in emissions were from military activity. ERG concluded the change in emissions were due to the revised generic military emission factors. ERG confirmed that in all the cases the military data with high emission differences were from generic activity. The percent difference between the older emission factor and the revised emission factor for NOx is 14,035%. The smaller absolute percent changes, such as the -36% change at Austin Bergstrom International Airport, are due to the use of AEDT vs EDMS. Additional details can be found in Table E-5.

E-11

Additional checks were conducted by looking at the top 25 airports in Texas to see if there were any additional outliers of concern. The TCEQ noticed that Hondo Municipal Airport seemed to have an unusually high level of activity. The original 2011 data were based on data the airport provided in 2008 and were grown using the growth factors in the FAA’s TAF dataset. Upon further investigation it was noted that Hondo Municipal Airport had unusually high LTO values in 2011 resulting in an unusually high calculated annual growth rate that, when applied to the airport-provided 2008 data, generated unrealistic 2011 values.

ERG replaced the elevated projected 2011 data with TAF data which was more consistent with the 2008 value. The correction was made to the data file and summary tables in the final report and included in this document as well.

Table E-5 provides a revised list of the top 25 airports where the Hondo Municipal Airport data has been corrected. In this table, there are some emission differences, but these are attributed to the following:

In comparing emission trends by airport with earlier inventory years, differences were noted that were attributed to the fact that the older 2011 emissions were based on the EDMS model, while other years were based on the FAA’s new AEDT model.

No changes were made since the FAA acknowledges the AEDT model provides notably different results than the EDMS model.

The new EPA generic military emission factors replaced the earlier factors provided in the SIP 1992 Guidance, which were based on engine test data from 1987 to 1991. The EPA’s new emission factors were derived from the International Civil Aviation Organization (ICAO) engine databank factors that were matched to U.S. military aircraft and weighted based on the current fleet composition. A comparison of the revised and previous generic military emission factors is summarized in Table E-6. (Eastern Research Group to United States Environmental Protection Agency Memorandum - Updating the Generic Military Emission Factors for the 2014 National Emission Inventory, December 15, 2015)

2 U.S. EPA, Procedures for Emission Inventory Preparation Volume IV: Mobile Sources, EPA420-R-92-009, December 1992.

The use of the latest EPA emission factors is consistent with developing inventories based on the latest data and methods currently available, and therefore no changes were made to these factors.

An additional concern was that Sheppard Airforce Base also seemed to have an unusually high level of activity. ERG first confirmed the data was correctly compiled.

However, since Sheppard is the busiest dual-use Air Force base in the U.S. it is to be expected that the base has a large number of LTOs compared to other airports in Texas (see https://www.sheppard.af.mil/News/Article-Display/Article/1412802/sheppard-has-busiest-joint-use-airfield-in-af/).

E-21

Differences of multiple orders of magnitude were noted for NOx emissions for generic military aircraft operations (including Sheppard AFB) between the 2011 and 2017 inventories, which matched the difference in the new EPA generic emission factors for military aircraft.

No change was required as the newer EPA emission factors replaced older emission factors developed in 1987.

In cases where quantitative data were developed, checks were made to ensure their accuracy. To this end ERG spot checked data and compared the calculated values to the previous 2014 trend inventories. The inventory data were also summarized for the TCEQ to evaluate independently. Data found to be questionable were examined in greater detail to determine if errors might be present and what adjustments might be needed. Where data were revised, the procedures and assumptions used were documented. The ERG Project Manager and task leads reviewed and approved all data adjustments. ERG also confirmed that all aircraft in the previous inventory were included in the input/output files used to develop the new 2011 inventory (see Table E-7). Note that the small difference in the first 8 rows of Table E-7 are due to the change in the Hondo Municipal Airport data. Hondo Municipal Airport data originally included some aircraft-specific local data. These were removed and replaced with generic data from TAF.

2011 Airports Compared to 2017 Airports

The airports in the 2011 inventory and the airports in the 2017 inventory were compared to identify differences in the datasets. As expected, there were changes during the 6 years, with some airports closing and some opening. The 29 airports that closed sometime between 2011 and 2017, or that did not have activity, are listed in Table E-8. These 29 airports were small and accounted for only 0.0526% of total LTOs in 2011 combined. 348 “new” airports opened during this time period or had activity in 2017 that was absent in 2011. These new airports were small, accounting for only 0.80% of total LTOs in 2017.

It should be noted that some airport codes changed between 2011 and 2017 and were in fact the same airports. These airports were not included in Tables E-8 and E-9.

These observations track with the significant increase in small aircraft facilities in the Dallas/Fort Worth area between 2011 and 2017. Many of these are very small operations, air taxis and helicopter services which have been increasing over the years.

No change was needed as the data seem to be capturing a new and growing trend.

2017 and 2020 to Previous 2017 and 2020 Comparison

ERG performed data checks comparing the 2017 and 2020 inventories, similar to the checks comparing the 2011 inventory using AEDT and revised generic emission factors, and the 2011 inventory using EDMS and the previous generic emission factors. Table E-10 summarizes the counties with an absolute difference of 1000% percent or greater, comparing the new 2017 inventory created using AEDT and EPA’s revised generic emission factors (from the 2017 trend inventory based on 2014 activity data) with that based on the prior EDMS model and the EPA’s older emission factors. Similar to 2011, there were some emissions with large differences. ERG then evaluated the data at the airport level within those counties to identify where the underlying issues were. These airports are summarized in Table E-11. For 2017 some of these differences were clearly caused by the differences in LTO data.

Since the 2017 trend inventory was based on 2014 data projected to 2017 instead of actual 2017 data, the LTO and projection data used in these different approaches appeared to be correct and were correctly applied, therefore no changes were required based on this QA check.

The data from Table E-11 showed that the LTO data matched although the emissions were significantly higher in the new 2017 inventory, as expected due to the differences in models and emission factors.

Therefore, no changes were required based on this QA check. In reviewing the data, ERG first confirmed the LTO values were correct, noting that the LTOs only increased from 4,305 to 13,300, a difference of only about 9,000 LTOs. In other cases, the emission differences were entirely due to LTO changes between 2014 and 2017 (for example see John R Armstrong Airport). If there was a large LTO change, ERG went back to the original data to ensure there were no transcription errors. ERG then checked with airports having significant changes in LTOs, verifying that the original source data was consistent with those changes.

For these reasons no changes were required based on this QA check. ERG then reviewed the data at the airport and SCC level, summarized in Table E-12. ERG confirmed the changes in emissions were due to generic military activity and the revised generic military emission factors. ERG also confirmed that in all the cases the military data with high emission differences were due to generic activity.

Therefore, no changes were required based on this QA check. Some of the variance in activity identified when comparing the 2014 and the 2017 inventories can also be attributed to the repeal of the Wright Amendment in October 2014. This amendment limited airport destinations in the Dallas/Fort Worth area (e.g., Love Field and Meacham Airports). Once the amendment was repealed, activity at Love Field and Mecham increased while activity decreased at Dallas/Fort Worth. Also, there was a decline in activity at smaller airports outside the Dallas/Fort Worth area (e.g., El Paso, Austin and Houston) where flights were being directed to when the amendment was enforced. These airports were no longer needed as a hub prior to leaving the state once the amendment was repealed.

E-42

Additionally, it was noted that for some airports the total LTOs were similar between years but shifted between SCCs. These can be seen in Table E-13. This is not unusual as specific aircraft can be used in general aviation, air taxis or commercial operations; for example, a Cessna Citation M2 may be privately owned as a general aviation aircraft or it may be owned by a business providing air taxi services, and if these services are regularly scheduled it may be considered a small commercial aircraft. It is often up to the airport to make these subjective determinations about which category the aircraft falls into as they are more likely to know how the aircraft is being used. The subjective aspect of assigning SCCs would explain why the LTOs can remain relatively consistent while the SCC assignments can vary. For aircraft specific data where the EPA updated their SCC assignments, ERG included these recent EPA changes in these inventories, which also accounted for some of the identified differences.

For these reasons, no changes were required based on this QA check. The aircraft counts in the AEDT input and output files were also compared to confirm that all aircraft were successfully imported into AEDT, as summarized in Table E-14.

No changes were required based on this QA check.

T-38 Talon 1 1 0 After the controlled inventory was developed by applying the airport level APU and GSE control strategies to the uncontrolled inventory, ERG compared the two inventories to confirm the control strategies were incorporated correctly. Table E-15 shows the difference in NOX emissions between the controlled and uncontrolled 2017 inventories.

No changes were required based on this QA check as the differences between the uncontrolled and controlled estimates reflected an expected decline in emissions.

Average -1.83 ERG performed the same comparison checks for 2020 as was done for 2017. The new 2020 statewide inventory (projected from the new 2017 baseline inventories) was compared to the previous 2020 inventory (developed from the Trend Analysis using the 2014 as the baseline). As expected, Tables E-16 to E-19 show differences/trends that are very similar to those seen in Tables E-10 to E-13. The small differences are due to the fact that the previous and recently projected 2020 inventories used factors based on the TAF data which have been updated since the 2014 inventory. ERG also confirmed that the aircraft used in the 2020 inventories matched the original aircraft used in the 2017 baseline as noted in Table E-20. Table E-21 shows the difference in NOX emissions between the controlled and uncontrolled 2020 inventories, similar to Table E-15 for 2017.

No changes were required based on this QA check.

E. Reconciliation with User Requirements

ERG applied basic quality assurance/quality control (QA/QC) considerations to conduct this project. As per the requirements of a Category III QAPP, 10% of these estimates were validated by ensuring that the emission estimates for 2011, 2017 and 2020 were consistent with the previous 2011 inventory, the 2017 trend inventories, and the 2020 trend inventories, respectively. Below is a summary of the QA findings:

Variance between earlier EDMS estimates and output from the FAA’s new AEDT model were consistent with the FAA’s expectations.

Elevated activity levels at Sheppard airport appear to be realistic as it is the largest mixed-use Air Force airbase in the U.S.

Increased air taxi activities in the Dallas/Fort Worth area have been noted by independent data sources.

Correct application of new EPA generic military emission factors that replace factors that are three decades old.

Repeal of the Wright Amendment accounted for changes for airports in the Dallas/Fort Worth Area as well as smaller connecting airports in El Paso, Houston, and Austin.

Based on the QA checks one corrective action was required and made:

Revised the 2011 Hondo Municipal Airport LTO data to use the FAA actual 2011 values from TAF in lieu of the grown 2008 local data using TAF growth rates that were in error.
