4 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/ Executive Summary Johnson & Johnson Vision Care (Ireland) operates a thermal oxidiser at its facility at National Technology Park, Plassey, Limerick to treat solvent emissions from five 3GT lens manufacturing lines. The hydration modules of these lines use isopropyl alcohol in the hydration process. The thermal oxidiser is the existing licensed main air emission point at the Johnson & Johnson Vision Care (Ireland) facility, emission point A2-1. For the purposes of a review application of the site s existing Industrial Emissions Licence (P ) this air dispersion model assesses the potential impact of the total organic carbon emissions from the thermal oxidiser, as well as nitrogen oxides and carbon monoxide. For the purposes of this modelling report a number of scenarios have been considered in order to fully assess the thermal oxidiser emissions. 1. Modelling of isopropyl alcohol (as Carbon), nitrogen oxides, and carbon monoxide emissions from the thermal oxidiser only in normal operation to determine maximum hourly and annual ground level concentrations 2. Modelling of isopropyl alcohol (as Carbon) emissions from the thermal oxidiser only in by-pass mode to determine maximum hourly ground level concentrations 3. Modelling of isopropyl alcohol (as Carbon) emissions from the thermal oxidiser only in by-pass mode to determine maximum annual (23.5 hours per day normal operation and 0.5 hrs per day in by-pass mode) ground level concentrations The aim of the modelling is to demonstrate that the main air emission point on-site does not result in a contravention of the applicable Irish Air Quality Standards and Environmental Assessment Levels. The assessment was carried out using the air dispersion modelling software AERMOD Version 7.10 and the modelling has been carried out in accordance with the EPA guidance document Air Dispersion Modelling from Industrial Installations Guidance Note (AG4). All calculations are based on 5 years of meteorological data (2008 to 2012), which was collected at the Shannon Airport met station. This is the nearest meteorological station, and is considered to be representative of the meteorological conditions experienced at the site. The modelling results indicate that the applicable ground level concentrations of the modelled pollutants will not result in any significant impact to the environment or human health.

5 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/ Introduction Johnson & Johnson Vision Care (Ireland) operates a thermal oxidiser (TO) at its facility at National Technology Park, Plassey, Limerick, to treat solvent emissions from five 3GT lens manufacturing lines. The hydration modules of these lines use isopropyl alcohol (IPA) in the hydration process. The TO is the existing licensed main air emission point at the Johnson & Johnson Vision Care (Ireland) facility, emission point A2-1. For the purposes of a review application of the site s existing Industrial Emissions Licence (P ) this air dispersion model assesses the potential impact of the total organic carbon (TOC) emissions from the TO, as well as nitrogen oxides (NO x ) and carbon monoxide (CO). The emission point model input data for the TO was that used in a previous modelling study (PM Group Report No RP-0001). The details of the emission parameters for the model are outlined in Section 3.6. The purpose of this model is proved an up-to-date model for consideration by the EPA in the licence review. For the purposes of this modelling report a number of scenarios have been considered in order to fully assess the proposed new air emissions from the facility. 1. Modelling of isopropyl alcohol (as Carbon), nitrogen oxides, and carbon monoxide emissions from the thermal oxidiser only in normal operation to determine maximum hourly and annual ground level concentrations (GLCs) 2. Modelling of isopropyl alcohol (as Carbon) emissions from the thermal oxidiser only in by-pass mode to determine maximum hourly ground level concentrations 3. Modelling of isopropyl alcohol (as Carbon) emissions from the thermal oxidiser only in by-pass mode to determine maximum annual (23.5 hours per day normal operation and 0.5 hrs per day in by-pass mode) ground level concentrations The purpose of the modelling is to demonstrate that the main air emission point on-site does not result in a contravention of the applicable Irish Air Quality Standards (AQSs) and Environmental Assessment Levels (EALs). These EALs are outlined in Section 2.1 below. The assessment was carried out using the air dispersion modelling software AERMOD Version 7.10 and the modelling has been carried out in accordance with the EPA guidance document Air Dispersion Modelling from Industrial Installations Guidance Note (AG4). All calculations are based on 5 years of meteorological data (2008 to 2012), which was collected at the Shannon Airport met station. This is the nearest meteorological station, and is considered to be representative of the meteorological conditions experienced at the site. 2.1 Environmental Assessment Levels Air Quality Standards for the protection of human health and the environment have been developed at European level and incorporated into Irish legislation. Air Quality Standards (AQSs) set limit values for GLCs of certain pollutants for both short-term (e.g. hourly, daily) and long-term (e.g. annual) averages. Limit values are often expressed as percentiles e.g. 98 percentile of mean hourly values which means that only 2% of the results obtained during the monitoring period can exceed the stated limit value. The AQSs which apply in Ireland are the Air Quality Standards Regulations 2011 (S.I. No. 180 of 2011). The relevant AQSs for this modelling study are outlined in Table 2.1.

Therefore, the relevant Danish C guideline limit value is 1000 µg/m 3 (Section , page 116 of Danish EPA Environmental Guidelines No. 1, 2002 Guidelines for Air Emission Regulation; Limitation of air pollution from installations). 1 The Regulations and Directive state that a sampling point targeted at the protection of vegetation and natural ecosystems shall be sited more than 20km from agglomerations or more than 5km away from other built-up areas, industrial installations or motorways or major roads with traffic counts of more than 50,000 vehicles per day, which means that a sampling point must be sited in such a way that air sampled is representative of air quality in a surrounding area of at least 1000 km 2. Therefore the annual NO x limit for the protection of vegetation would not directly apply to the area in which the facility is located. IE RP-0002_A_01 Page 6 of 25 Formal Issue

7 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/ Air Dispersion Modelling 3.1 Dispersion Model The air dispersion modelling input data consists of meteorological data, detailed information on the physical environment (including building dimensions and terrain features) and design details regarding the emission point (TO). Using this input data, the model predicts ambient ground level concentrations beyond the site boundary for each hour of the modelled meteorological years. The model post-processes the data to identify the location and concentration of the worst-case ground level concentrations. Emissions from the proposed site have been modelled using the AERMOD dispersion model (Version 7.10) which has been developed by the U.S. Environmental Protection Agency (USEPA). The model is a steady-state Gaussian plume model used to assess pollutant concentrations associated with industrial sources. The model has been designated the regulatory model by the USEPA for modelling emissions from industrial sources in both flat and complex terrain. 3.2 Meteorological Data The meteorological data required by the dispersion model is wind speed, wind direction, Pasquill- Gifford stability category, boundary layer height and ambient temperature. The stability category and boundary layer height are used to characterise the turbulence within, and the height of the lower levels of the atmosphere. Extremely unstable conditions can cause plume looping and elevated concentrations close to the stack. Under stable conditions elevated concentrations can occur due to the emissions being trapped below the boundary layer. Neutral conditions, characterised by cloudy skies and strong winds, are most favourable for dispersion due to the mechanical mixing of the lower atmosphere. The wind direction determines the direction in which the plume is blown, and for a particular stability, higher wind speeds will result in reduced plume rise so causing the plume to reach ground level closer to the stack with elevated emission concentrations. The boundary layer height determines the total vertical distance over which the plume may spread. The model has been run for each pollutant using 5 years (2008 to 2012) of meteorological data from the Shannon Airport met station. The meteorological windrose for each of the five years is presented in Figure Building Downwash Air streams blowing across buildings can become disrupted, with turbulent eddies occurring downwind in the building wake. If an emission point is sufficiently close to a building, then the plume may become entrained in the turbulent eddies of the building wake. This entrainment can cause plume downwash resulting in elevated emission concentrations close to the emission point. The stacks modelled are subject to downwash and, as a result, direction specific building dimensions are calculated. The AERMOD model interprets the influence zone of each building for a given wind direction using the Building Profile Input Program (BPIP). All of the main buildings on the site were included in the modelling analysis, including warehouses, office/labs area, production building, etc. 3.4 Receptors The model was set up to examine the impact of emissions on the area surrounding the site of the proposed facility using a series of receptors. A receptor is a location at which the model will calculate maximum process contributions. A nested grid with 3 receptor grids of varying resolution centred on the site was established.

8 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/ Terrain A 4000m x 4000m grid with receptors at 100m spacing was created. Around this a coarser 10km x 10km grid with 500m receptor spacings was created. Finally a 20km x 20km grid with 1000m receptor spacings was positioned around the site. A terrain height for all of the model elements was input to the model in order to accurately represent the changing elevations of the surrounding landscape. The area in the vicinity of the Johnson & Johnson Vision Care (Ireland) facility cannot be classified as flat terrain, therefore digitised terrain data was incorporated into the model using a Digital Elevation Model (DEM) file and the AERMAP function of the AERMOD software.

10 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/ Stack Discharge Parameters and Emission Data This section outlines the inputs to the model in relation to the facility emission points. The model inputs are tabulated in Table 3.1 below. The emissions data used for the TO is that previously modelled for the Johnson & Johnson Vision Care (Ireland) site (PM Group Report No RP-0001). A maximum volumetric flow rate of 10,000 Nm 3 /hr was used at the emission limit concentrations of 75mgC/Nm 3 for TOC, 200mg/Nm 3 for NO x and 100mg/Nm 3 for CO, as per the facility Industrial Emissions Licence for normal operations. The stack height, internal diameter and exit gas temperature have not changed from the previous modelling. The by-pass operating mode has also been modelled to simulate 30 minutes by-pass operation and 30 minutes normal operation in any 1-hour period (as per Condition 5.6 of the facility s Industrial Emissions Licence bypass of the TO is permitted for up to 30 minutes in any one day). Therefore the worst case scenario operation over any 1-hour period is the average of the normal and by-pass emission levels of 75mgC/Nm 3 and 5391mgC/Nm 3, respectively. This approach is used to determine the hourly and annual maximum ground level concentrations when by-pass mode is used.

11 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/ Modelling Results Tables 4.2 and 4.3 outline the results of the modelling exercise. Reported are the maximum hourly values, annual values and the relevant percentiles of hourly values. Contour plots have also been produced using the AERMOD 3D Analyst software tool and Google Earth Pro for each scenario and are included in Appendix A. It is noted that for the maximum hourly and annual GLCs of TOC predicted by the model as presented in Tables 4.2 and 4.3 have been converted from carbon to IPA, in order to compare against the EALs for IPA. Predicted Environmental Concentrations (PECs) (i.e. background concentrations plus modelled process contributions) were also calculated for NO x (as NO 2 ) and CO (background concentrations for IPA are not available) and averaging time, for comparison to AQSs and EALs. This assessment ensures that both the modelled emissions and the existing background concentrations are taken into account when determining the possible overall ambient air quality once the proposed facility is operational. Background concentrations for the area for NO x (as NO 2 ) and CO have been taken for Zone C from the EPA publication Air Quality in Ireland 2014 Key Indicators of Ambient Air Quality, Limerick is included in Zone C. Averaged annual mean ambient NO 2 and CO data for 2014 for all the monitoring stations in Zone C, is summarised in Table 4.1 below. Table 4.1: Annual Mean Ambient Air Quality Data Pollutant Parameter Annual Mean Concentration (µg/m 3 ) Zone C Nitrogen Dioxide (NO 2) 8 Carbon Monoxide 200 In relation to annual mean values for NO 2, the background concentrations were added directly to the maximum annual predicted concentrations for human health. In relation to combining the short term (hourly) peak contributions with background concentrations, guidance from the Appendix E of the EPA AG4 Guidance Note advises that the background concentration should be twice the annual mean value added to the short term process contribution. These background concentrations have been combined with the predicted GLCs in order to determine the PECs. IE RP-0002_A_01 Page 11 of 25 Formal Issue

14 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/ Discussion of Model Results 5.1 Model Assumptions A number of assumptions were made during the study which is consistent with the conservative approach of this report. These assumptions are: - Throughout the assessment a worst-case assumption for operating hours was used (See Section 2). - Emissions were modelled at full load and at licensed emission concentration and flow limits - The highest predicted concentrations at any off-site location were used in the assessment of environmental effects. - The highest predicted concentrations obtained using any of the five different years of meteorological data have been used in this assessment. - The most stringent AQSs and EALs were used in the study. 5.2 Comparison of All Results with Irish AQSs and Irish EALs As can be seen from the results all of the predicted maximum GLCs both for hourly and annual averages are below the relevant AQSs or EALs for all modelled scenarios. It is noted that the results for NO x (as NO 2 ) appear high, even though they are still below the relevant AQSs, while including background concentrations. This is due to the fact that they were modelled at the maximum emission limit allowed for in the site s Industrial Emissions Licence. In reality, the emissions concentration of NO x from the TO are a fraction of the emission limit of 200mg/Nm biannual monitoring of the TO for NO x (as NO 2 ) yielded results of 4.6mg/Nm 3 and 4.3mg/Nm 3, which is approximately 2% of the emission limit in the licence. Therefore in terms of GLCs of NOx (as NO 2 ), this would equate to 2% of the results given in Table 4.2, which would be well below the AQSs for NO x. 5.3 Comparison of IPA Results with Danish C Values For the purposes of completing the study the 99 percentile of hourly average GLCs of IPA from each of the scenarios were also compared to the Danish C-value. The 99 percentile of hourly average GLCs for Scenario 1 (for normal operations) will not exceed the Danish C-value for IPA (as carbon). However in the scenario where the TO is in by-pass mode, i.e. Scenario 2, the Danish C limit value is exceeded. The IPA Danish C limit is expressed as the 99%ile of the maximum hourly average values and is equal to 1,000 μg/m 3. This means that the limit of 1,000 μg/m 3 can be exceeded 1% of the time, i.e. 87 hours per year. However since the by-pass condition has been modelled as continuous the resulting 99 percentile of the maximum hourly value is an overestimation. It contains the inherent assumption that the periods during which the TO may be run in by-pass mode will coincide with the weather conditions that will produce the worst GLCs. This is an extremely conservative assumption. It is more likely that TO by-pass occurrences will coincide with a range of weather conditions varying from very good to very poor (with respect to air dispersion). From the Industrial Emissions Licence Condition 5.6 it was determined that the 1-hour emissions modelled under Scenario 2 is only permitted to occur a maximum of 4.2% of the time (i.e. 1 hour in every 24 hour period). This is equivalent to 365 hours per year. As stated above the maximum hourly value can exceed the IPA Danish C limit 87 hours per year which is 24% of the time the TO is in by-pass mode (87/365 = 24%). Therefore on an average basis this is equivalent to a 76%ile of the maximum hourly value ( = 76). The 76%ile of the maximum hourly value for Scenario 2 is μg/m 3 which is only 10% of the Danish C limit of IPA (as carbon). On this basis, it is concluded that the atmospheric emissions IE RP-0002_A_01 Page 14 of 25 Formal Issue

15 Johnson & Johnson Vision Care (Ireland) Industrial Emissions Licence Review IE RP-0002, Issue A 09/03/2016 from the proposed plant are not likely to exceed the applicable Environmental Assessment Levels (EAL), including the Danish C limit. 6 Conclusion Given the results outlined above it is concluded that the emissions of TOC (as C), NO x, and CO from the TO at the Johnson & Johnson Vision Care (Ireland) facility will not lead to any contravention of Irish air quality standards and environmental assessment levels and therefore there is no predicted significant impact to the environment or human health.
