Executive Swnmary/Certification of Results

Iralco are in the process of applyin, 0 to the Environmental Trotection Agency (EPA) for an Integrated Pollution Control (IEX) Licence for activities classified under Section 12.2 of the First Schedule of the Environmental Protection Agency Act, 1992, S.I. No. 07 of 1992, as

‘The manufacture or use of coating materials in processes with a capacity to make OY use at least IO tonnes per year of organic solvents and powder coatings with a capacity to produce at

least 50 tonnes per year ’

Jialco is required to monitor its emissions to atmosphere as part of a baseline environmental investigation programme associated with acquisition of the @PC) Licence. A comprehensive atmospheric emission monitoring programme was undertaken on 24 point sources located throughout the facility by Bord na Mona Environ-mental Consultants and Scientists between the 12th of September and the 26’ of November 2002 for the following parameters: volumetric flow, particulate matter, metals, Total Organic Carbon (TOC as C), acid gases, ammonia and sodium hydroxide.

For spray painting operations, the BATNEEC emission limit value for particulates is 3 mg/m3. This limit is exceeded by emission points A2-2, A2-6 and AZ8 and A2-20. The BATNEEC Guidance Note for the Manufacture or Use of Coating Materials does not specify an ELV for particulate matter for other processes. In this absence, the T A L&t, Technical Instructions on Air Quality 2001 may be referenced. All non spraying operations do not exceed the 20mg/m3 BATNEEC guide value.

Results obtained for all metals for all emission points sampled were detected at levels Iess than the relevant analytical limit of detection for individual metals and subsequently for total metal content. However, due to the high analytical detection limits for the metal analysis, the results appear to exceed the T A Luft Class III guide vaIue for total metals. However, as the metal content cannot exceed the particulate matter level (see Tables 4.2 and 4.3), there are only two emission points, namely A2-6 and A2-8, that may have exceeded the T A Lufi (2001) guide value of lmg/m3.

The TOC (as C) emissions from A?!-1, A2-6 and A2-10 determined during this monitoring event, exceed BATNEEC limit values of 100 mg/m3 for coating processes within Class 12.2 activities. However, for all other emission points monitored, the relevant emission limit value is not being exceeded. Levels of hydrofluoric acid (HI?) obtained in all point source emissions monitored are below the T.A. Luft Class TI concentration and mass emission limits of 3mgIm3 and 15g/h respectively. The level of ammonia detected at the outlet of AI-22

(Electrobrightening Plant) during this monitoring event is considered low at 0.36 mg/m3 and is below the T A Luft ELV of 30mg/m3.

Emission point A2-22 exceeds the relevant guide value (one fortieth the Occupational Exposure Limit) for nitric acid. The guide value for sulphuric acid is exceeded for emission points AI-1 and A2-22. Emission point A2-21 exceeds the 0.05 mg/m3 guide value (l/40” the OEL) for phosphoric acid. The WaOH concentration for emission point A2-22 exceeds its guide value (1/40th the OEL). All other parameters monitored fall within the relevant guide

values. Furthermore, the concentrations of the above acids and NaOH are considered low.

This report is certified as accurate and representative of the sampling and associated analysis carried out.

1.0 INTRODUCTION

Iralco are in the process of applying to the Environmental Protection Agency (EPA) for an Integrated Pollution Control (IPC) Licence for activities classified under Section 12.2 of the First Schedule of the Environmental Protection Agency Act, 1992, S.I. No. 07 of 1992, as:

’ The manufacture OY use of coating materials in processes with a capacity to make OY use at least IO tonnes per yeav of organic solvents and powder coatings with a capacity

to produce at least 50 tonnes per year’

Iralco are required to monitor their emissions to atmosphere as part of a baseline environmental investigation programme associated with acquisition of the (II%) Licence. A comprehensive atmospheric emissions monitoring programme was designed following a survey of the main point sources of atmospheric emissions on

the Iralco site undertaken by Bord na M6na Environmental Consultants in conjunction with personnel from the Iralco Environmental Department. The monitoring

programme was undertaken on 24 point sources located throughout the facility by Bord na Mona Environmental Consultants and Scientists between the 12th of September and the 26ti of November 2002 for the following parameters:

9 Volumetric flow 9 Particulate matter 9 Metals 9 Total Organic Carbon (TOC as C) 9 Acid Gases 9 Ammonia 9 Sodium hydroxide

This report details the samplin g and analytical methodologies employed and also includes a broad interpretation of the results obtained.

2.0 MONITORING PROGW AND METHODOLOGIES

Section 2.1 provides details of the sampling and analysis methodologies employed for the determination of the various parameters during the monitoring programme.

Section 2.2 provides brief details in a tabulated format of the monitoring programme, including point source identification and description; sample locations and parameters (refer to Table 2.1). All those categorised as main emissions were automatically inchrded in the monitoring programme.

For all point source emissions with abatement equipment in place (e.g. cyclones, wet scrubbers etc.), monitoring was performed downstream of the abatement equipment at the final emission to atmosphere outlet, with the exception of emission source A2-2. In the case of AZ-2 (Paint Plant Primer Booth Extraction Unit), sampling downstream of the abatement equipment was not possible due to physical sampling constraints.

2.1 METHODOLOGIES

2.1.1 Volumetric Flow and Temperatures

Volume flow was measured in accordance with the British Standard BS 3405 for average velocity in a duct. A standard L-type pitot tube and digital manometer or Gravimat isokinetic sampler was used to record velocity pressures. The measurements were taken at ten equidistant points along each axis (two where appropriate). Temperature measurements will also be recorded to coincide with the collection of stack gas samples using a k-type thermocouple. The results for temperature and volumetric flow are expressed in “C and Nm3/‘hr respectively.

2.1.2 Particulate Matter

Particulates were determined in accordance with the British Standard BS3405. Samples were collected isokinetically on pre-weighted quartz filters using the Gravimat SHC 500 isokinetic sampler. Each sample was collected over a minimum of 30 minutes, during a period of operation considered by Iralco operators to be representative of normal working conditions for the particular process. Following the sampling period, the weight gain was determined gravimetrically using a 5-point calibrated balance. The filters were then be dispatched to the Bord na Mona laboratory for metal analysis as detailed in Section 2.3 below. Results for total particulate matter are expressed in mg/Nm3 and as a mass emission in kg/hr.

2.1.3 Metal Content

The concentration of a wide range of metals (Pb, Fe, Bo, As, Sn, Cd, Cu, Sb, Hg, Be, Cr, Co, Se, Ag, MO, Zn, Mn, Ni, Al and Ba) was determined by subsequent acid digestion of the filters used in the total particulate matter monitoring and analysis using Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) in accordance with the ASTM standard methods. Results for individual metals detected and total metal content are expressed in mg/Nm3 and as a mass emission in kg/hr.

2.1.4 Total Organic Carbon (TOC as C)

Total Organic Carbon (TOC’s) quantified relative to methane, were determined using a Signal Total Organic Carbon analyser. The instrument employs flame ionisation detection and is calibrated against a reference methane standard prior to the commencement of the measurement programme. Monitoring was conducted over a minimum of 30 minutes, during a period of operation considered by Iralco operators to be representative of normal working conditions for the particular process. Results from the instrument averaged over the total sampling period were expressed as TOC in ppm (methane equivalent). The results were subsequently converted to mg/Nm3 expressed as TOC as C (relative to methane) also expressed in kg/In-.

2.1.5 Acid Gases Q included Phosphoric (&P04), Sulphuric and Nitric Acids (HNO3) Monitoring

The sampling and analysis of the acid gases was conducted based on US EPA Method 26a. Samples were collected via a filter chamber containing a glass fibre filter, and through a series of four impingers using specialised SKC sampling pumps at a flow rate of approximately lml/min. A dry gas meter recorded the total volume sampled. The first two impingers contained either dilute sulphuric acid or deionised water to trap the anions; the third impinger was empty and the fourth contained silica gel. Each sample was collected over a minimum of 30 minutes, during a period of operation considered by Iralco operators to be representative of normal working conditions. Analysis of the impinger solutions was carried out using ion chromatography. The results are expressed in ms/Nm3 and kg/&-.

2.1.6 Ammonia Monitoring

Samples were collected via a series of impingers using specialised SKC sampling pumps at a flow rate of approximately ll/rnin. A dry gas meter recorded the total volume sampled. The first 2 impingers contained dilute sulphuric acid to trap the ammonia content, the third impinger was empty and the fourth contained silica gel. Sampling was carried out over a minimum of 30 minutes, during a period of operation considered by Iralco operators to be representative of normal working conditions. Analysis of the impingers was carried out using ion chromatography. The results are expressed in mg/‘Nm3 and kgihr.

2.1.7 Sodium Hydroxide Monitoring

Samples were collected via a sampling line through a cellulose ester mix (CE%f) filter followed by a deionised water impinger using specialised SKC sample pumps. Sampling was carried out over a minimum of 30 minutes, during a period of operation considered by Iralco operators to be representative of normal working conditions. Analysis of both the impinger solution and the filter (subsequent to acid digestion) for sodium content was carried out using Inductively Coupled Plasma 1Ma.s~ Spectroscopy (ICP-MS) in accordance with the ASTM standard methods. The results are expressed in mgNm3 and kg/l-n as sodium hydroxide.

3.0 COMMITMENT TO QUALITY

3.1 LAB ACCREDITATION

Bord na Mona Technical Services (Technical Services) analytical laboratories is ILAB accredited by the National Accreditation Board (NAB) since 1997. It has always been the policy of the laboratories to achieve and maintain a high standard of quality consistent with client’s requirements in all aspects of the work carried out within the laboratory.

Bord na Mona ECS laboratories successfully transferred to the new standard of accreditation IS0 17025 on the 161h of November 2001.

3.2 Accredited to IS0 17025

This new standard contains all of the requirements that testing laboratories have to meet if they wish to demonstrate that they operate a quality system, are technically competent, and are able to generate technically valid results. IS0 17025 incorporates all those requirements of ISO 9001 and Is09002 that are relevant to the scope of testing services that are covered by the laboratory’s quality system. Thus a laboratory that complies with IS0 17025 will therefore also operate in accordance with IS0 9001 or IS0 9002.

3.3 Interlaboratory Proficiency Schemes

To ensure the accuracy of the analytical testing we participate in several external proficiency schemes. The ongoing competence of the laboratory and its staff is assessed by participation in various inter-laboratory proficiency testing schemes, such as Aquacheck and the EPA scheme organised for environmental laboratories throughout h-eland.

3.4 EPA Quality Control Register

Bord na Mona ECS Analytical Laboratories performance in the EPA intercalibration

scheme has insured its listing on the EPA’s register of Quality Controlled Laboratories. Both accredited and non-accredited test methods are assessed by these schemes.

5.0 DISCUSSION

Tables 4.1 to 4.7 present the results of the recent air monitoring programme carried out at the Iralco facility, in Collinstown, Mullingar, Co. Westmeath. Where available, results obtained are compared to emission limit values listed in the BATNEEC Guidance Note for the Manufacture or Use of Coating Materials.

5.1 Particulate Matter Emissions

Particulate matter results for 13 point source emissions sampIed are presented in Table

4.2. For spray painting operations, the BATNEEC emission limit value for

particulates is 3 ms/m3. This limit is exceeded by emission points A2-2, A2-6 and A2-8 and A2-20.

The BATNEEC Guidance Note for the Manufacture or Use of Coating Materials does not specify an ELV for particulate matter for other processes. In this absence, the T A Luft, Technical Instructions on Air Quality 2001 may be referenced. Section 5.2.1 therein states that ‘the dust emissions contained in any waste gas may not exceed a mass flow of 0.2Okg/h or a mass concentrations of 20mg/m3. Even with a mass flow smaller than or equal to 0.2Okg/h, a mass concentration of 0.15g/m3 in the waste gas may not be exceeded’.

All non spraying operations do not exceed the 20mg/m3 BATNEEC guide value.

5.2 Total Metal Emissions

Total metal results (inorganic particle matter) from 22 point source emissions sampled are presented in Table 4.3. In the absence of limit values in the BATNEEC Guidance Notes for the Coating Industry, comparison of results obtained is made to the guide values stated in Section 5.2.2 of the T A Lufi 200 1 Technical Instructions.

concentration in the waste gas shall for coinciding Class II and IIT substances shall not exceed a total of lmg/m3. Analysis of field blank quartz filters using Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) yields background levels of a variety of metals, resulting in a high analytical limit of detection for such metals.

Results obtained for all metals on sample filters were detected at levels less than the relevant analytical limit of detection for individual metals and subsequently for total metal content, However, due to the high analytical detection limits for the metal analysis, the results appear to exceed the T A Luft Class III guide value for total metals. However, as the metal content cannot exceed the particulate matter level (see Tables 4.2 and 4.3), there are only two emission points, namely A2-6 and A2-8, that may have exceeded the guide value of lmg/m3.

5.3 Total Organic Carbon (TOC) Emissions

r

TOC results (as C, relative to methane) for 21 point source emissions sampled during this assessment are presented in Table 4.4. Comparison of results obtained should be made to the ELV’s listed in Tables 5.1 and 5.4 of the BATNEEC guidance notes for Class 12.2 activities as represented below in Tables 5.2 and 5.3 respectively.

Iralco utilise greater than 15 tonnes of solvents per annum. Consequently, the limit values for Total Organic Carbon (as C) for the coating process applies. In comparison with the results in Table 4.4 with the aforementioned limit values, emissions from M-1, AZ-6 and A2-IO during this monitoring event, exceed the 100 r&m’ for the coating process. However, for all other emission points monitored, the relevant emission limit value is not being exceeded.

In addition, attention should also be paid to the emission limit values for waste gases listed within the EU Council Directive 1999/13/EC of 11 March 1999 ‘on the limitation of emissions of volatile organic compounds due to the use of organic solvents in certain activities and installations ’ which has been enacted into Irish law under S. I. No. 543 of 2002. Activities undertaken at Iralco are defined in Annex I of this Directive (Activity No. 8 - other coating, including metal, plastic, textile, fabric, film and paper coating), with an annual solvent consumption threshold in excess of those listed in Annex ILA (lower solvent threshold value of 5 tonnes/annum). The requirements within the Directive pertaining to atmospheric emissions of TOC’s for ‘existing installations’, therefore also apply to I&co. The relevant emission limit values for TOC’s(as C> in the waste gases listed in Annex IL4 or the requirements of the ‘reduction scheme’ listed in Annex III3 shall be complied with within specific time periods. Limit values of 50 mgNm3 applies to coating processes for installations with solvent consumption greater than 15 tonnes/annum. Existing installations must comply with these limits no later than 3 1 October 2007. However, existing installations which operate existing abatement equipment and complies with the ELV of 150 mg/m3 shall be exempt Tom the aforementioned ELV’s for a period of 12 years after the date referred to in Article 1.5, i.e. April 2013.

With the exception of emission point sources AZ-l, A2-2, A2-4, A2-5, A2-6, A2-8, A2- 9, A2-10, A2-11, A2-12 and A2-13 all other emission points monitored during this assessment are within the limit values of 50 mg/Nm3 for coating processes. No item of

abatement equipment is in place for emission point sources A2-1, M-6 and A2-10 and therefore the higher ELV of 150 mg/m3 does not apply.

5.4 Acid Emissions

Results for acid emissions from 3 point source emissions sampled are presented in Table 4.5. In the absence of comparison with relevant BATXEEC ELV’s for levels of acids obtained, attention may be paid to the ELV’s listed in T.A. Luft (German Technical Instructions on Air Quality Control - T.A. Luft 2001) guideline values for Vaporous or Gaseous Inorganic Substances, Classes I to IV as represented in Table 5.4.

Levels of hydrofluoric acid (HP) obtained in all point source emissions monitored are below the T.A. Luft Class 1T concentration and mass emission limits of 3.0 mg!m3 and 15 g/h respectively. Levels of nitric and sulphuric acid were detected in AZ-22 ( Electrobrightening plant, scrubber exhaust) at concentrations of 1 .Q9 and 10.2 mgIm3 respectively. The level of phosphoric acid detected was less than the analytical limit of detection of 0.39 mdm3. 9.44 mg/m3 of sulphuric acid was detected in the emission fi-om A2-1. No ELV’s are available witbin BATNEEC, T.A. Luft or Danish EPA guidelines specifically for discharges of sulphuric, nitric or phosphoric acids to air. In this absence, a small fraction of the Occupational Exposure Limits (QELs) published by the National Authority for Occupational Safety and Health (NAOSH) and listed in the 2001 Code of Practice for the Safety, Health and Welfare at Work (Chemical Agents) Regulations 2001 may be used. The level commonly used is one fortieth of the Short Term Exposure Limit (STEL). These guide values are 0.25 ms/m3, 0.05 mg/m3 and 0.025 mg/m3 for nitric, phosphoric and sulphuric acid respectively. Emission point A2-22 exceeds the relevant guide value for nitric acid. The guide value for sulphuric acid is exceeded for emission points A2-1 and AZ-22. Emission point A2-21 exceeds the 0.05 mg/m3 guide value for phosphoric acid.

.

5.5 Ammonia and Sodium Hydroxide Emissions

Results for ammonia and sodium hydroxide emissions from A2-22, the scrubber exhaust in the Electrobrightenin g Plant are presented in Tables 4.6 and 4.7 respectively. Under the T A Luft Technical Instructions on Air Quality Control 2001, ammonia is classed as a Class III Inorganic substance and assigned a guide value of 30mg/m3 at a flow rate of O.lSkg/h. The level of ammonia detected at the outlet of emission point A2-22 during this monitoring event is considered low at 0.36 mg/m3 with a mass flow of ~0.005 kg&r and hence is significantly below the T A Luft guide value. No ELV’s are availabIe within BATNEEC, T.A. Luft or Danish EPA guidelines for discharges of sodium hydroxide to air. Guidance may be obtained from one fortieth of the OEL (0.0530mg/m3) as stated in the 2001 Code of Practice for sodium hydroxide. The concentration for emission point A2-22 exceeds this guide.
