1 Introduction This technical appendix updates the analysis and assessment undertaken in the Environmental Statement (ES) published in February 2018. It only presents changes to the assessment and does not repeat the information contained in the air quality sections of the ES and the associated technical appendices 10.1 to 10.5, much of which remains current and valid. It should be read along with the Environmental Statement Addendum (ESA) Air Quality Chapter.

It is structured as follows:

• Section 2 presents information on modelled receptors (previously presented in the ES Appendix 10.1);

• Section 3 presents information on the emissions methodology (previously presented in the ES Appendix 10.2);

• Section 4 presents information on traffic data (previously presented in the ES Appendix 10.3);

• Section 5 presents further information on the baseline conditions in the study area;

• Section 6 presents information on the model setup and verification (previously presented in the ES Appendix 10.4);

• Section 7 presents results from sensitivity tests undertaken for the ESA; and

• Section 8 presents information on the predicted pollutant concentrations (previously presented in the ES Appendix 10.5).

Committed Developments Table 1 presents the details of the additional nine committed developments in the study area that have been used as future receptors in the ESA assessment. At the time of assessment, there was no confirmed list of committed developments from Uttlesford District Council (UDC). Even though UDC committed developments have not been explicitly included in the air quality model, results can be extracted from the contour plots at these locations.

3 Emissions Methodology Aircraft Engines For the annual aircraft movements recorded at the airport in 2019, nine modelling categories (MCATs) were defined for inclusion in the air quality model (as was previously done for the 2018 ES). However, a more detailed breakdown has been included in the ESA assessment for the calculation of emissions within each category, weighted by the aircraft movements. Table 2 presents these MCATs and the representative aircraft type within each, along with the engine and air traffic movements for the baseline year 2019. Table 3 presents the data for the future assessment scenarios. Table 2: Aircraft types, engine selection and ATMs for baseline year 2019 scenario

For piston engines (MCAT 1a), emission factors were obtained from the FOCA database and for turboprop engines (MCAT 1c) they were obtained from the FOI confidential database. Table 4 presents the NOx emission factors (in g/kg) and fuel flow (kg/s) for each engine and thrust setting used in the assessment (85%, 30% and 7%) for the baseline year 2019. Table 5 presents similar information on emission factors and fuel flow for the future assessment scenarios. The ICAO air quality manual suggests that engines use 100% thrust during take-off. However, this is a conservative assumption and the thrust setting depends on the aircraft’s take-off weight and ambient temperature. Actual take-off thrust for large jets is usually 75-90%. The air quality assessment has used a thrust setting of 85% for all aircraft which is a common assumption. This may be an under-estimate for some types of aircraft but will over-estimate for others. The emissions from take-off roll are ground level on the runway and would not significantly affect concentrations at receptors further away from the airport boundary.

The method used for deriving PM10 emissions is the same as the 2018 ES. Table 6 and Table 7 present the smoke number and hydrocarbon emission factors for the turbofan engine aircraft for the baseline and future assessment scenarios respectively. Table 8 and Table 9 present the calculated PM10 emission factors for each thrust setting for the baseline and future assessment scenarios respectively. In the 2019 baseline year assessment, PM10 emissions for turboprop aircraft (MCAT 1c) were assumed to be the same as for the Learjet 45 aircraft (engine GA TFE731-20BR) in MCAT 1b. For the future assessment years, PM10 emissions for turboprop aircraft were assumed to be the same as for the Piper PA-31 Navajo aircraft (Cessna Citation engine) in MCAT 1b.

Engines emissions of future aircraft In the 2018 ES, LTO NOx emissions were predicted to reduce in magnitude in the Development Case scenarios due to newer engines which were only introduced in the future assessment scenarios. For the ESA assessment, since the newer engines have now been introduced in the baseline year 2019, no improvements are anticipated in the future assessment scenarios. In addition, at the time of writing the 2018 ES, no emissions information was available in the ICAO databank regarding the Leap-1A engines used for the Airbus A320neo and A321neo, and the Leap-1B engines used for the Boeing B737 Max8. The 2018 ES therefore used an estimate of emissions reductions based on predicted improvements in fuel use. There is currently information on the emissions of these engines in the ICAO databank and these have been used in this assessment. The ICAO databank includes several variants of these engines; for the air quality assessment the variants with the highest emissions have been used as a worst case. Table 10 presents a comparison of the bypass ratio, rated thrust, total LTO NOx and fuel flow for the engine variants of the engines used for the A320neo, A321neo and B737 Max8 aircraft (Leap-1A and Leap-1B engines) and comparison against the engines for the A320, A321 and B738 aircraft. It can be observed that the Leap-1A engines on the A320neo aircraft have a higher bypass ratio, but similar rated thrust compared to the engines in the A320 aircraft. The total LTO NOx emissions and fuel flow are both lower for the A320neo compared to the A320 by approximately 22% for NOx and 19% for fuel. The Leap-1A engines on the A321neo also have a higher bypass ratio, but similar rated thrust compared to the engines in the A321 aircraft. The total LTO fuel in the A321neo is approximately 21% lower than in the A321. However, the total LTO NOx emissions are higher in the A321neo by approximately 13% compared to the A321. The Leap-1B engines on the B737 Max8 aircraft have a higher bypass ratio compared to the engines in the B738 aircraft. However, there are several variants with a range of rated thrust; some below or similar to the B738 engines and others much higher. The total LTO fuel in the B737 Max8 is lower than in the B738 with a range of 11-15% depending on the variant used. However, the total LTO NOx emissions are lower for the Leap-1B21/23 variants compared to the B738 aircraft, but are higher for other variants with a difference of up to 65%. The ESA assessment has used the variant with the higher emissions as a worst case. Therefore, it can be seen that even though the newer engines are more fuel efficient, their total LTO NOx emissions are higher than the older engines. As described by the European Aviation Safety Agency (EASA), “more fuel efficient engine cycles, often made possible through the use of new materials, has led to increasing pressures and temperature within the combustor”. This subsequently leads to an increase in NOx emissions. As a result, the ESA assessment predicts higher emissions in the future assessment scenarios compared to the 2018 ES.

* Engine variant used in the ESA assessment. The Committee on Aviation Environmental Protection (CAEP) was established in 1983 and forms a technical committee of the International Civil Aviation Organization (ICAO) Council. Its purpose is to form policies and establish standards relating to aviation environmental impact. For air quality, regulatory limits for engine NOx emissions have been set and these are referred to by the corresponding CAEP meeting number. The engine emissions certification process is based on the LTO cycle and involves running an engine on a test bed at each thrust setting. The most recent certification data include comparison against the CAEP/8 standards. Work is ongoing by CAEP for newer and more stringent standards and the current programme is for the CAEP/12 cycle (2019-2022). Figure 2 presents where the engines used in the ESA assessment fall in relation to the CAEP standard. Even though most of the engines used for the future assessment scenarios meet the latest CAEP/8 standard, there are still a few that meet older standards. This is a conservative case and in reality, most of the engines operating in 2032 should be meeting at least the CAEP/8 standard if not later versions of the standards.

Aircraft Engine Testing Detailed data on aircraft engine testing was provided by STAL for 2019. The data included tests at the engine testing ground in front of Hangar 8 and idle runs at the stands. There were 238 tests during the year at the engine testing ground. The aircraft types for these tests were classified into their respective MCATs and emissions were calculated using the same approach as for the aircraft in the LTO cycle. An average time of 49 minutes and a thrust setting of 85% was used in the calculation. A diurnal profile was also applied, as shown in Figure 4.

Figure 4: Diurnal profile for engine testing ground

There was a total of 920 idle runs at the stands in 2019. The aircraft types for these runs were classified into their respective MCATs and emissions calculated using the same approach as for the aircraft in the LTO cycle. A duration of 5 min and a thrust setting of 7% was used in the calculation. The location of modelled sources for engine testing ground and engine idle runs are unchanged since the 2018 ES.

Fire Training Ground Detailed data on the consumption of LPG for the fire training ground was provided by STAL for 2019. There was a total of 3,407 litres of LPG consumed in the year at the fire training ground. A diurnal profile was applied to the baseline year 2019 as a full years’ worth of training was carried out between September and December due to a refurbishment project which prevented the fire simulator from being used until September. The diurnal profile is shown in Figure 5. No diurnal profile was applied for the future assessment years. The location and model parameters remain unchanged from the 2018 ES.

Ground Support Equipment Data for airside vehicles at the airport was provided by STAL, consisting a record of all licensed vehicles for airside access, date of registration, fleet owner, type of fuel and fuel consumption in litres for 2019. The methodology of the emission calculations and the location of modelled sources for GSE at the airport remain unchanged since the 2018 ES. There was a total of 337 airside vehicles, of which 197 were classified as non-road mobile machinery (NRMM) and 140 as road vehicles. The road vehicles consisted of 80% light duty vehicles (LDVs) and 20% heavy duty vehicles (HDVs). Table 15 to Table 17 present the relevant emission standards for NRMM and road vehicles. Table 15: NRMM emission standards

A total of 206,310 litres of fuel were consumed by airside vehicles, of which 98% was diesel and 2% was petrol fuel. The emission factors and assumptions made for NRMMs remain unchanged from the 2018 ES. For airside road vehicles, the methodology for obtaining the emission factors and assumptions made for vehicle travelling speed (20mph) are the same as the 2018 ES. For LDVs, emissions were calculated for a light commercial vehicle less than 3.5 tonnes, separately for diesel and petrol fuel (as was for the 2018 ES too) and assuming a consumption of 24.2 mpg (13.05 litres per 100 km). For HDVs, the assumptions remain unchanged from the 2018 ES. Table 18 presents the emission factors for these vehicles.

Heating Plant Detailed data for the annual gas consumption of heating plant (natural gas boilers) was provided by STAL for 2019. Table 19 presents the thermal input information for each boiler at the airport. Figure 6 presents the monthly fuel consumption data, which was used to create a monthly profile for the air quality model. The methodology for emission calculations, the location of modelled sources and model input details for the heating plant remain the same as in the 2018 ES.

4 Traffic Data Highway Network Traffic data for roads was provided by the transport consultants (Steer) and in the same format as the 2018 ES. The extent of the modelled road network remains unchanged from the 2018 ES. The traffic data for road ID 31 was not provided for the ESA, and therefore the flows were derived based on the adjoining roads (IDs 32 and 35). Table 20 to Table 22 present the traffic data flows (airport and non-airport related) used in the air quality assessment, while Table 23 presents the change in annual average daily traffic (AADT) and HGV flows between the DC and DM scenarios in 2027 and 2032.

Car Parks Table 24 presents the traffic data flows for the car parks around the airport. The data is presented as AADT flows (in and out flows) and were provided by the transport consultants (Steer). The Short Stay Green car park was a surface car park in the 2018 ES, but has been converted to a multi-storey car park with six levels and this has been included in the ESA assessment. The locations of the modelled car parks are the same as the 2018 ES. Table 24: Traffic flows for car parks

The air quality monitoring which has been undertaken at the airport by STAL in recent years show that annual mean NO2 concentrations are well below the air quality objective. Figure 7 shows the trend of NO2 concentrations at the airport automatic monitoring sites since 2009 which indicate a slight downward trend in recent years.

Figure 8: Trends in NO2 measurements at the airport

Figure 9 presents the trends in air quality measurements at the centre of Bishop’s Stortford at the two monitoring sites of concern at Dunmow Road and London Road. Measurements of NO2 concentrations at these sites have consistently been over the air quality standard of 40µg/m3 over the past years. However, concentrations have been reducing in over the past five years. Measurements for 2019 were not available at the time of assessment.

The monitored PM10 concentrations at the airport were well below the air quality objective of 40µg/m3 for all years since 2009. Figure 10 shows the trend of PM10 concentrations at the airport automatic monitoring sites. A decrease in PM10 concentrations is indicated in recent years. The monitoring of PM2.5 at the airport undertaken by STAL commenced in 2018. The recorded concentrations for 2018 and 2019 have been well below the air quality standard of 25µg/m3 and below the World Health Organization (WHO) guideline2 value of 10µg/m3. Figure 11 shows the PM2.5 measurements at the airport automatic monitoring sites.

Background Concentrations The methodology for calculating hourly varying total background concentrations for the study area remain unchanged from the 2018 ES. The locations of the rural background monitoring sites used in the ESA assessment are presented in Figure 11. The Chilbolton Observatory site has been used as a replacement of the Harwell site due to its decommissioning.

Figure 12: Rural background monitoring sites and area of gridded background emissions

Figure 12 presents the angles used for the meteorological data for each background monitoring station. For example, when the wind was between 307° to 52° the background NOx data from the Wicken Fen rural monitoring station was used. With regards to particulate matter, only data recorded at the Chilbolton Observatory and Rochester Stoke monitoring stations were used, since particulate matter concentrations are not recorded at the other two monitoring stations.

East Herts Air Quality Planning Guidance The East Herts Air Quality Planning Guidance3 requires the determination of the classification of a proposed development at stage 1 of the air quality assessment process. Table 26 shows the criteria specified in the guidance and how these are met or not by the proposed airport development. The proposed development is classified as a “major” development and a detailed air quality assessment has been undertaken. Table 26: East Herts air quality planning guidance criteria for development classification

Criteria Criteria met (Y/N) Reasoning

Land use classes A, B, C or D exceeding thresholds, requiring a transport assessment N The proposed development of an airport does not fall into use

classes A, B, C or D. Development generating 30 or more two-way vehicle movements in any hour n/a The air quality assessment has used AADT flows and not hourly

movements.

Development generating 100 or more two-way vehicle movements per day Y

The development is predicted to generate more than 100 two-way vehicle movements per day on 16 roads in 2027 and 18 roads in 2032 in the study area.

Development proposing 100 or more parking spaces N There are no changes in the number of parking spaces as a result

of the proposed development. Development proposed in a location where the local transport infrastructure is inadequate N The proposed development is not in an area where local transport

infrastructure is inadequate.

Development proposed in a location adjacent to an AQMA N

The closest AQMA from the proposed development is the Bishops Stortford AQMA which is located 3.5km west of the proposed development.

Proposals within or adjacent to an AQMA N The closest AQMA from the proposed development is the Bishops Stortford AQMA which is located 3.5km west of the proposed development.

Proposals that will create an AQMA N It is not expected that an AQMA would be created as a result of the proposed development.

Proposals that increase existing traffic flow on roads of > 10,000 AADT by 5% or more Y

There are five roads in 2027 and 10 roads in 2032 which have an AADT of 10,000 or more and are predicted to increase by 5% or more as a result of the proposed development.

Proposals that increase traffic 5% on road canyons with > 5,000 AADT N The criterion was not met for those road canyons identified in the

study area. Proposals that could introduce or significantly alter congestion and introduction of substantial road infrastructure changes

N It is not expected that the proposed development would introduce or significantly alter congestion and there are no substantial road infrastructure changes proposed as part of the development.

Proposals that reduce average speeds by more than 10kph N The proposed development is not expected to change average

speeds on roads in the study area.

Proposals that include additional HGV movements by more than 10% of total trips Y

The proposed development is predicted to increase HGV movements by more than 10% of total trips on one road in 2027 and six roads in 2032.

Significant demolition and construction works proposed N No significant demolition or construction works are proposed.

6 Model Setup and Verification Model Setup Meteorology The model requires hourly sequential meteorological data as an input. Data from Stansted Airport for 2018 and 2019 were obtained for the air quality assessment. The 2018 meteorological data was used for modelling background concentrations only. Table 27 presents the percentage of calm and usable hours for each year. It can be observed that there were less than 1% calm hours for both years and the usable hours of data exceeded the 90% threshold described in Defra’s TG16 guidance. Figure 13 presents the windroses for both years and it can be observed that the prevailing wind direction in the study area is from the south-west.

Other Model Parameters The model parameters of surface roughness and minimum Monin-Obukhov length are unchanged from the 2018 ES. Model Verification No update to the model verification was undertaken for the ESA assessment due to limited availability of 2019 air quality monitoring data by the local authorities at the time of assessment. However, the same adjustment of road traffic emissions within Bishop’s Stortford and Stansted Mountfitchet has been applied for the ESA assessment.

7 Sensitivity Testing Aircraft LTO emissions to 3,000ft The 2018 ES and the ESA assessment have included emissions up to 1,500ft altitude for the landing and take-off cycle. Work previous undertaken for other airports has shown that emissions over 1,500ft in altitude have an insignificant contribution to ground level concentrations. Aircraft take-off emissions Take-off emissions for aircraft have been calculated using 85% thrust. A sensitivity testing has been undertaken for the change in emissions if 100% thrust was used. Table 28 presents the change in take-off emissions between 85% and 100% thrust settings. It can be observed that there is an average increase in NOx emissions by 94% in the 2027 and 116% in the 2032 scenarios. In relation to PM emissions, there is an average increase of 41% in 2027 and 36% in the 2032 scenarios. Table 28: Comparison of take-off emissions between 85% and 100% thrust

The percent change in emissions due to 100% thrust has been applied to the take-off contribution at this receptor for all assessment scenarios and the total concentrations re-calculated for NOx and PM10. It has been estimated that this receptor would experience a small increase in total NOx concentrations due to the 100% take-off thrust. The change in NOx concentrations due to the scheme would increase from 0.23μg/m3 (85% thrust) to 0.31μg/m3 (100% thrust) in 2027 and from 0.45μg/m3 to 0.79μg/m3 in 2032. However, the total NOx concentrations would remain below 22μg/m3 across all scenarios and therefore there would be no material change to the air quality impacts at this receptor. In relation to PM10 concentrations, there would be an insignificant change in concentrations of less than 0.01μg/m3 as a result of the 100% take-off thrust. Receptor R137 (Hockerill Court, London Road) is predicted to experience the highest total concentrations in the study area. The 100% take-off thrust would increase total NOx concentrations by 0.05μg/m3 in the DC 2027 and 0.08μg/m3 in the DC 2032 scenarios. There would be an insignificant change in both NOx and PM10 concentrations due to the scheme of less than 0.01μg/m3 and therefore there would be no material change to the air quality impacts at this receptor. The closest ecological site to the runway is Elsenham Woods SSSI. The highest NOx concentrations at the site have been predicted to be well below 30μg/m3 in both 85% and 100% take-off thrust scenarios. The change in NOx concentrations due to the scheme would increase from 0.16μg/m3 (85% thrust) to 0.20μg/m3 (100% thrust) in 2027 and from 0.32μg/m3 to 0.51μg/m3 in 2032. However, the total NOx concentrations would remain below 22μg/m3 across all scenarios and therefore there would be no material change to the air quality impacts at this site. Overall, there would be no material changes to air quality impacts from a take-off thrust setting of 100% compared to 85% which has been used in the ESA assessment. Speed of airside vehicles (GSE) GSE have been assumed to be travelling at a speed of 20mph (32kph). A sensitivity test has been carried out assuming an average travelling speed of 5kph to account for idling vehicles. Table 30 shows the differences in emissions between a speed of 32kph and 5kph for all assessment scenarios.

Arup


The GSE emissions for 5kph speed are 28% higher than for 32kph speed. In the baseline year 2019, the highest modelled NOx concentration from GSE was at receptor R39. At this receptor, the total predicted NOx concentration was 24.9µg/m3 of which 0.2µg/m3 are attributed to GSE. The 28% increase in emissions would account for an increase of approximately 0.06μg/m3 at this receptor which is insignificant. As the contribution of GSE is very small at receptors further away from the airport, it is unlikely that using a speed of 5kph would lead to any material changes in the impact of the proposed development.

Research suggests that ammonia emissions are only significant very close to the roadside within about 20m. The Hatfield Forest SSSI and NNR is approximately 35m from the B1256 Dunmow Road. This is the closest road to the ecological site. There is no increase in road traffic along this road as a result of the proposed development for any of the future assessment years (Table 32). Therefore, there would be no change in ammonia emissions that could affect this ecological site and this element has been scoped out. The Elsenham Woods SSSI is adjacent to Hall Road. This is the closest road to this ecological site. There is no increase in road traffic along this road as a result of the proposed development for any of the future assessment years (Table 32). Therefore, there would be no change in ammonia emissions that could affect this ecological site and this element has been scoped out. Table 30: Traffic data on closest roads to ecological sites

ER2s North site boundary south 28.60 28.62 0.02 0.15% Concentrations along the M11 and A120 Policy ENV13 of the Uttlesford District Council (UDC) Local Plan (2005) specifies a zone 100m on either side of the central reservation of the M11 and a zone 35m either side of the centre of the A120 as needing special consideration in relation to air quality impacts. The ESA assessment includes assessment at discrete points where sensitive receptors have been identified and also as a 15x15km2 grid. This section presents the results of the assessment for the zones of concern along the M11 and the A120, with data extracted from the contour plots. It is not appropriate to calculate air quality impacts within the roads themselves or very close to them, since in reality no development would be built immediately adjacent to a motorway. The analysis has therefore looked at the predicted concentrations at the 100m zone for the M11 from a distance of 15m from the edge of the motorway and at the 35m zone for the A120 from a distance of 5m from the edge of the road. The A120 zone has been defined across the whole length of the road within the study area, which crosses both council areas as shown in Figure 35. M11 zone of 100m The average NO2 concentrations along this zone have been predicted to be 19.8μg/m3 in the DC 2027 and 15.8μg/m3 in the DC 2032 scenarios. The average predicted change in NO2 concentrations due to the scheme has been predicted to be 2.4μg/m3 in 2027 and 0.7μg/m3 in 2032. It is therefore estimated that there would be slight adverse impacts in 2027 and negligible impacts in 2032 as a result of the proposed development. The average PM10 concentrations along this zone have been predicted to be 13.3μg/m3 in the DC 2027 and 13.0μg/m3 in the DC 2032 scenarios. The average predicted change in PM10 concentrations due to the scheme has been predicted to be 0.5μg/m3 in 2027 and less than 0.1μg/m3 in 2032. It is therefore estimated that there would be negligible impacts in both 2027 and 2032 as a result of the proposed development.

The average PM2.5 concentrations along this zone have been predicted to be 10.5μg/m3 in the DC 2027 and 10.3μg/m3 in the DC 2032 scenarios. The average predicted change in PM2.5 concentrations due to the scheme has been predicted to be 0.3μg/m3 in 2027 and less than 0.1μg/m3 in 2032. It is therefore estimated that there would be negligible impacts in both 2027 and 2032 as a result of the proposed development. A120 zone of 35m The average NO2 concentrations along this zone have been predicted to be 20.2μg/m3 in the DC 2027 and 16.8μg/m3 in the DC 2032 scenarios. The average predicted change in NO2 concentrations due to the scheme has been predicted to be 1.9μg/m3 in 2027 and 0.9μg/m3 in 2032. It is therefore estimated that there would be negligible impacts in both 2027 and 2032 as a result of the proposed development. The average PM10 concentrations along this zone have been predicted to be 13.5μg/m3 in the DC 2027 and 13.3μg/m3 in the DC 2032 scenarios. The average predicted change in PM10 concentrations due to the scheme has been predicted to be 0.4μg/m3 in 2027 and 0.1μg/m3 in 2032. It is therefore estimated that there would be negligible impacts in both 2027 and 2032 as a result of the proposed development. The average PM2.5 concentrations along this zone have been predicted to be 10.6μg/m3 in the DC 2027 and 10.5μg/m3 in the DC 2032 scenarios. The average predicted change in PM2.5 concentrations due to the scheme has been predicted to be 0.2μg/m3 in 2027 and 0.1μg/m3 in 2032. It is therefore estimated that there would be negligible impacts in both 2027 and 2032 as a result of the proposed development.
