Irish Cement Ltd Objection to Proposed Determination

Introduction

August 201 7

The EPA initiated a review of Industrial Emissions licence register number POO30-04 for the purposes of updating the licence to incorporate the requirements of Commission Implementation Decision 201 3/163/EU of 26 March 2013, establishing the best available techniques (BAT) conclusions under Directive 201 0/75/EU of the European Parliament and ofthe Council on industrial emissions for the production of cement, lime and magnesium oxide. Irish Cement Ltd (ICL), Platin received a Proposed Determination VD) of its application for a revised Industrial Emissions Licence, Register No POO30-05 on the lSt August 2017,

It is the opinion of ICL that:

The Agency appears to have included a number of features in the Proposed Determination for the manufacture of cement that more correctly apply to incineration of waste including the following:

o The gases h m Kiln 2 are split and vented separately through the Kiln Stack and coal mill, so duplication of monitoring provides no environmental benefit,

o With the exception of dust the operation of the coal mill does not alter the emissions.

o As a result of the specific conditions of clinker manufacture the "natural" oxygen concentration at the top of the Preheater Tower is significantly below IO%, in contrast to the incheration process in which the oxygen concentration is much higher,

o Due to the requirement to maintain and improve the energy efficiency of the clinker manufacturing process the ingress of 'false air' into the system is avoided where possible. Higher levels of false air would not only increase gas flow volumes but also require increased heat input through additional he1 combustion with the associated additional environmental impacts.

o The parameters of SW1, SW2, SW3 are all constant due to the retention time in the system and dominance of the quan-y water

o No wastewater or emuent arises h m abatement of emissions

0 The Agency has not correctly applied a number of the BAT Conclusions in the PD for Irish Cement Platin factory and

The Agency has in its PD placed Irish Cement at an unfbir competitive disadvantage in relation to other cement manufacturers in Ireland by failing to ensure a consistent application of the environmental regulations for the sector.

10. No derogation for “dormant” plant

Irish Cement is also of the opinion that the principle that the Industrial Emissions Directive (IED) should lead to a largely level playing field in the EU has not been applied in this PD.

The licence should be founded on the E D and on the BAT Conclusions as these are the legal instruments that must underpin the decisions of the competent authority, the Environmental Protection Agency (EPA).

These objections are described in more detail below.

POO30-0.5 Irish Cement Ltd Objection to Proposed Determination August 201 7

The main aim of the Industrial Emissions Directive is to prevent, reduce, and as far as possible eliminate pollution arising from industrial activities'. The development o f an integrated approach to controlling emissions will also contribute to the achievement ofa level playingfield in the Union by aligning environmental peijjiormance requirements for industrial installations?

Following on h m the Industrial Emissions Directive, BAT Reference Documents @REFS) have been developed for various industries; the BAT conclusions contained are adopted by the Commission as Implementing Decisions3. The IED requires that these BAT conclusions are the reference for setting permit condition^.^ The introduction to the BAT conclusions on industrial emissions for the production of cement, lime and magnesium oxide states the following:

Article 16(1) of Directive 2010/75/EUpruvides that the monitoring requirements in the pennit referred to in point (c) of Article 14(1) of the Directive are to be based on the concIessions on monitoring as described in the BAT conclusions.

Irish Cement Ltd Objection to Proposed Determination August 201 7

Objection No 1 : Basis of Standardisation of Emissions from Kiln Activities to Reference Oxygen Concentration

4.1 Introduction The formula for standardising concentrations of substances in combustion gases has been well-established for many years. The methodology for standardising concentrations of substances in combustion gases to a reference oxygen concentration is to allow for varying oxygen Concentrations and to take account of any dilution air.

4.2 Proposed Condition Proposed Condition 4.2.2 sets out the basis for correcting of concentrations measured in emissions to atmosphere with respect to temperature pressure and oxygen.

4.2.2 From combustion sources &In activities):

Temperature 273K, Pressure 101.3 P a , dry gas; 10% oxygen.

The standardisation of gas volumes to this oxygen reference value shall be done only ifthe oxygen content measured over the relevant sample period exceeds the reference oxygen value.

4.3 BAT As per Article 14 (3) of the IED “BAT ConcIusions shall be the reference for setting the permit conditions”. The methodology for expressing concentrations at a standard reference concentration is set out on pages 7 and 8 (BAT Conclusions).

Emission levels associated with the best available techniques (BAT-AELs) given in these BAT conclusions refer to standard conditions: dty gas at a temperature of 273 K, and apressure of 1 013 hPa.

Values given in concentrations apply under the following reference conditions:

Kiln activities in the cement industry: 10% oxygen by volume

Conversion to referenee oxygen concentration

The formula for calculating the emissions concentration at a reference oxygen level is shown below:

Where:

ER (mgNms): emissions concentration related to the reference oxygen level OR

OR (voI %):

EM (rnghh’): emissions concentration related tu the measured oxygen level OM OM (~01%): measured oJcygen level

reference oxygen level

The BAT Conclusions do not allow for any deviation h m this formula if the concentration of oxygen is less than 10%.

4.4 Discussion The formula for standardising concentrations of substances in combustion gases has been well-established for many years.

1. The methodology for standardising concentrations of substances in combustion gases to is set out in the EPA Air Emissions Monitoring Guidance NoteAG2 (2014).

2. As mentioned above, BAT Conclusions for the cement industry (2013) (pp. 7 and 8) state:

Emission levels associated with the best available techniques (BAT-AELs) given in these BAT conclusions refer to standard conditions: dry gas at a temperature of 273 K, and a pressure of 1 013 hPa.

Values given in concentrations apply under the following reference conditions:

Kiln activities in the cement industty: 10% oxygen by volume

3. The E D (20 10) states in AiVNEX F7 - Technicalprovisions relating to waste incineration plants and waste eo-incinerution plants, Part 4,Z. 1 :

AI1 values are standardised at IO % oxygen. 2. I

The preamble in Proposed Condition 4.2 correctly refers to the need to exclude any dilution air (also called “false air“) that may be introduced to the process & combustion has taken place. Minimisation of dilution air or false air is energy-efficient and should not be discouraged by failing to give credit by allowing correction to the standard of 10% vlv oxygen if the actual concentration is below this. Irish Cement believes that the Agency has misapplied BAT in including this proposed condition.

This proposed condition is not workable. It cannot be complied with. Furthermore, it is not included in the BAT Conclusions for the cement industry.

Further, reduction of dilution air (also known as false air) is a measure to improve energy efficiency. Failure to allow correction to 10% oxygen of concentrations of substances

when the oxygen level is below 10% is a major impediment to achieving further energy efficiency by reduction of dilution air or false air,

Irish Cement firther notes that this incorrect proposed condition has not been universally applied for all cement manufacturing facilities under its jurisdiction. The Agency should not depart from the approach of applying BATC in a balanced manner to all cement plants without a good objective reason. To do so in inequitable and undermines the principle of equal treatment of competitors in a particular sector.

4.5 Appeal Accordingly Irish Cement requests the deletion of the final paragraph of Proposed Condition 4.2.2:

The standardisation of gas volumes to this oxygen reference value shall be done only ifthe oxygen content measured over the relevant sample period exceeds the reference oygen value.

Objection Point No. 2 Emission Limit Values and Associated Monitoring Requirements fur Coal Mills

5.1 Introduction Irish Cement has made extensive inquiries with other cement manufacturers in the EU and has found that no cement plants in the EU have had ELVs imposed for continuous monitoring of atmospheric emissions from coal mills other than particulates, including when emissions from kiln activities are vented through coal mills. In Germany, monitoring of particulates and spot measurements for the other parameters are carried out in coal mills. See letter b m VDZ, German Cement Association (Appendix 1).

In particular, ICL notes that the Agency has imposed ELVs on coal mills at other cement facilities for particulates only and that the required monitoring of particulates is periodic with quarterly ftequency only. This discrepancy is in conflict with the aim of the E D to achieve a level playing field by aligning environmental performance requirements.

The Agency should not depart from the approach of applying BATC in a balanced manner to all cement plants without a good objective reason.

This misapplication of BATC is a fundamental flaw in the approach of the Agency in drafting the PD for Irish Cement Platin, as this results in a PD that is in sharp contrast to PDs issued to other cement manufacturers.

The direct monitoring of Kiln 2 gases and of Kiln 3 gases fulfils completely the requirements of BAT5 regarding kiln processes. Coal Mill 1 would exhaust gas h r n Kiln 3 so as to create an inert atmosphere fbr safe operation. This exhaust gas would be supplied to Coal Mill 1 post abatement in the kiln itself and in the SNCR unit. Coal Mill 1 gases and Raw Mill 1 gases would be vented through a shared stack. Monitoring of Coal Mill 1 gases would be therefore not required as it would merely duplicate monitoring of Kiln 3 gases.

Similarly, Coal Mill 2 requires exhaust gas h m Kiln 2 so as to create an inert atmosphere for safe operation. This exhaust gas is supplied to Coal Mill 2 post abatement in the kiln itself and in the SNCR unit. Monitoring of Coal Mill 2 gases is therefore not required as it would merely duplicate monitoring of Kiln 2 gases.

Discussion See attached Figure 1 for a schematic representation of the relevant equipment and monitoring points for Kiln 2 and Coal Mill 2. The configuration is similar for Coal Mill 1 &RawMilll /Kiln3.

No chemical processes take place in either coal mill. No substances are added to the gas stream in either coal mill other than particulates. The only process that occurs in the coal mills is a physical process, that of size reduction i.e. grinding/milling. Post the kiln activity, part (approximately 10%) of the gases from Kiln 2 pass through the Coal Mill 2 to provide an inert atmosphere within the coal mill and thereby minimise the risk of a coal dust explosion. Gases from Kiln 2 are abated and monitored in accordance with the provisions of BATS.

Similarly, when Coal Mill 1 is in operation a smal l portion of the gases from Kiln 3 are passed through Coal Mill 1 to provide an inert atmosphere within the coal mill and thereby minimise the risk of a coal dust explosion. Gases fiom Kiln 3 are abated and monitored in accordance with the provisions of BATS.

The monitoring of the Kiln 2 gases and Kiln 3 gases post abatement fulfils the requirements of BAT5 regarding monitoring of kiln activities. As Coal Mill 1 and Coal Mill 2 use a portion of the kiln gases that have been abated in Kiln 3 and Kiln 2 respectively and in the SNCR Units it is not necessary to duplicate the monitoring of coal mill gases, other than for particulates (as particulates are generated in the coal mill). The proposed schedule for monitoring as presented in the PD for Coal Ml l 1 and Coal Mill 2 is not in accordance with BAT requirements.

BATS d, e and f refer to the monitoring of dust, NOx, SOX, PCDD/F, HCI, HF, TOC and CO emissions and are clearly applicable to kiln processes only. BAT5g which relates only to the monitoring of dust is applicable to non-kiln activities.

BAT1 8 provides emission levels for dust emissions h m the flue gases of cooling and milling processes:

The BAT-AEL for dust emissions from theflue-gases of cooling and milling processes is <io - 20 mg/Nm3, as the daily average value or average over the sampling period (spot measurements for at least hay an hour). When applying fabric filters or new or upgpaded ESPs, the laver level is achieved.

To impose ELVs and require monitohg for any emission parameters from coal mills other than particulates is in conflict with the BAT Conclusions for the cement sector.

Irish Cement notes that other cement producers in Ireland who operate their coal mills in a similar mode are required only to measure for particulates on a quarterly basis. Irish Cement requests that this monitoring regime should apply to Coal Mill 2 and Coal Mill 1.

Although not required by BATS, Irish Cement would not oppose a requirement that in addition to the above that emissions from Coal Mill 1 and Coal Mill 2 be monitormi quarterly for the first 12 months of the licence or the first 12 months of operation after the grant of the licence, whichever is later, and, with approval of the Agency, annually thexafter for the emission parameters that are required to be monitored in in Kiln 2 stack

6 Objection Point No. 3: Emission Limit Value for NOx for Kiln 2 and Kiln 3

Preheater kilns

6.1 . Introduction The proposed ELV outlined in Proposed Schedule C. 1.1 for nitrogen oxides WOx) that applies to Kiln 2 gases and to Kiln 3 gases is 450 mg/Nm3. Irish Cement believes that the Agency has misinterpreted the information in the application submitted to the Agency as part of the BAT review. The information, included in Irish Cement h u a l Environmental Reports, shows that the initial NOx level &er primary techniques is > 1000 m m m 3 and the plant therefore qualifies for the higher BAT-AEL of 500 mg/Nm3.

I

mg4Vm3 < 200 - 450 (I) (2)

6.2 Proposed Licence Condition Emission Limit Values and monitoring requirements for Kiln 2 (A2-02) and Kiln 3 (A2- 08) are set out in the PD - SCHEDULE C: Emissions, Monitoring and Control, C.1 Emissions to Air, C. 1:l Description, limit values and monitoring at comblastiun gas emission points reference number: A2-01, A2-02, A2-03 and Al-08 and referenced in Proposed Conditions 1.6,5.1 and 6.4).

The ELV for NOx emissions fiom Kiln 2 and Kiln 3 has been reduced from 500 mg/Nm3 (in Licence Register No POO29-03) to 450 mg/Nm3 (24-hour mean).

6.3 BAT BAT 19 specifies BAT-associated emission levels for NOx from the flue-gases of kiln firing and /or prehmtiuglprecalching processes in the cement industry which are as follows:

6.4 Discussion This discussion focuses on two aspects:

0

0

6.4.1 Emission Limit Value

The relevant ELV to be applied to Kiln 2 and to Kiln 3, and

The time required to ensure compliance with the revised limit.

In order to reduce NOx emissions h m the fluegases of kiln processes, a number of measures are proposed.

NOx emissions are abated using selective non-catalyhc reduction (SNCR) on Kiln 2 and Kiln 3.

Kiln 3 in-line calciner is designed to deliver optimal heat economy, power consumption and NOx reduction. Kiln 2 has burner pipes designed for optimal combustion to assist NOx reduction.

The NO, limit of 50hg/m3 is applicable as Kiln 2 (A2-02) is a preheater kiln with an initial level after primary techniques of > 1. ,000mg/m3. The average NO, concentration measured at Kiln 2 on an annual basis (24 hour rolling average) h m 2003 to 2008 ranges from 1,007 to 1,383 mg/Nm3 NOx. This was the NO, concentration prior to SNCR on Kiln 2. Kiln 2 temporarily paused operation in November 2008 and ran only for a brief period in 20 12 (1 0 days).

The BAT conclusions state that “The upper level of the BAT-AEL; range is 500 mg/Nm 3, ifthe initial NO, level @er primary techniques is > 1,000 rng4Vm3.’’ As the initial concentration of NO, is greater than 1,000 mg/Nm3, ICL are applying for BAT AEL of 500 mg/Nm3 for Kiln 2.

Irish Cement has a concern that this explanation may have been misunderstood. Irish Cement wishes to clarify why an ELV of 500 mg/Nm3 is appropriate and in accordance with BAT19.

Table 3 below shows the average concentration of NOX in the Kiln 2 stack for the years 2003-2008, prior to the installation of the SNCR. It is clear that the initial concentration of NO, was above 1,000 mg/Nm3 after primary techniques. See Note 1 in Table 2 fiom BAT Conclusions above.

Kiln 2 has not run since 2008 and no monitoring data is available to determine BAT compliance. When full operation of Kiln 2 resumes, ICL propose to monitor emissions and will endeavour to comply with the BAT emission limit values. If compliance with BAT emission limit values cannot be complied when in full operation, a planned programme of improvement towards meeting the limits will be submitted to the Agency.

Commissioning of Kiln 3 (A2-08) and its associated SNCR commenced in December 2008 and detailed monitoring data was collected in the years 2009 and 20 10 when the kiln used pet coke as its sole fuel.

Therefore Irish Cement qualifies for an ELV at the upper level of BAT-AEL 500 mg/Nm3.

6.4.2 Time required to compIy The Inspector's report on the Proposed Determination states that:

... the CID establishing BAT conclusions under Directive 201 0/75/EU on industrial emissions for the production of cement was published in 2013. A four-year lead period was allowed for installations to bring their activities into compliance. n e licensee has not provided adequate technical justdJcation for the existing limit to continue for a period, as required by Article I5 of the Indmb-ial Emissions Directive 201 0/75/EU.

While the intent of the BAT Conclusions is outlined in the BATC document, it was not known which ELV in the permitted range the EPA would actually propose to impose in its licence in respect of Kiln 2 and Kiln 3. This lack of certainty directly impacts the licensee in making preparations for installing equipment to meet a future unknown ELV. Without sight of the PD ELVs, ordering of equipment would have resulted in the licensee procuring and installing equipment that might not be required or might not be sufficient to ensure that emissions would meet the actual imposed ELV.

Irish Cement is committed to taking measures to reduce emissions of nitrogen oxides from the Kiln 2 stack by upgrading the SNCR NOx suppression system. The programme has already been commenced and, in light of the comments of the Inspector referred to above, the Agency's attention is drawn to S.S6(l)(b)(xvii) o f the Environmental Protection Agency Act 1992. We set out below the entire programme for this with dates for completion.

7.4

Irish Cement Ltd Objection to Pr~posedDeternainatjion August 201 7

Discussion The ELVs for SO2 in the current licence were set at 50 mg/Nm3. By Technical Amendment C to the current licence, these ELVs were reduced to 48 mg/Nm3.

The reduction in ELVs was made so that when the GBS Drier was put into service, the total mass emission rate of sulphur oxides h m the facility were unchanged. The Agency's view is that one of the pre-conditions of a Technical Amendment is that the total emissions h m a facility cannot be increased.

Therefore Irish Cement requests that the ELV for SOX be restored to the value in the original current licence, POO30-04, i.e. 50 mg/Nm3, This is the lower limit of the range quoted in BAT2 1. There is no reason to maintain an incongruous ELV value of 48 mg/Nm3. In order to ensure that permitted emissions of SOX are not increased Irish Cement would accept a reduction in the ELV for the Emission Points A2-02 and A2- 03 from 400 mg/Nm3 to 390 mg/Nm3. The reduction in permitted emissions fiom A2-02 and A2-03 would total 4.3 1 kg/ht, The increase in permitted emissions h m A Z O 1 and A2-08 would total 0.918 kg/hr. These changes would secure a net reduction in permitted emissions of SOX of 3.392 kg/hr. It must also be noted in Schedule B. I , Emissions to Air of Licence POO30-04 the ELV of 48 mg/Nm3 for SOX as SO2 at A2-08, is only applicable when co-incinerating waste. The limit when not co-incinerating waste is 398 mg/ Nm3. For consistency Irish Cement requests that the lower ELV for SO2 applies only when co-incinerating waste at emission point A2-08. Should A2-08 revert to using fossil Euel only, then the ELV would revert to 390 mg/Nm3. This is consistent with the ELV set value for A2-02 in the proposed determination as there is ody permission to burn fossil fuel at this emission point, currently.

7.5 Appeal Irish Cement requests that the ELV for SOX tor A241 and A 2 - O X be restored to the value in the original current licence, POO30-04, i.e. 50 mg/Nm3 as SO2 when co-incinerating waste and that the ELV for A2-02, A2-03 and A2-08 be reduced to 390 mg/Nm3, when using fossil fuel only..

However, the report of the Inspector on the application for a review of the licence has commented on a number of aspects of the application:

The example used to illustrate the environmental benefit of increasing the gas flow, 362,656 Nm3/hr, is significantly below the licence limit.

8.4 Discussion Dr Rosholm (FL Smidth) has prepared a supplementary report to update his earlier (May 2017) report prepared on behalf of Irish Cement. His supplementary report (included in Appendix 2 to this Objection document) outlines the improvement in clinker production (tonne per day) and the associated energy saving (kcal per kg of clinker) benefit that an increase in Kiln 3 gas volume to 477,878 Nm3/hr could achieve.

8.4.1 Background In his supplementary report, as in his previous report, Dr Rosholm demonshtes that the existing Kiln 3 system can be optimized by increasing kiln gas flow to achieve an increase in clinker production with a higher energy efficiency. The following BAT conditions were reviewed in this context:

POO30-05 Irish Cement Ltd Objection tu Proposed Determination August 201 7

8.4.2 Process Optimization The Inspector made comments regarding two aspects of the May 20 17 Report by Dr Rosholm:

The example used to illustrate the environmental benefit of increasing the gas flow, 362,656 Nm3h, is significantly below the licence limit.

Optimization was not demonstrated at the current ELV.

These have been addressed in the supplementary Report in Appendix 2.

Dr. Rosholm has simulated 3 scenarios namely:

1. Kiln 3 gas flow at 362,656 N m 3 h and associated efficiencies - current scenario

2. Kiln 3 gas flow at 409,063 Nm3/hr and associated efficiencies - at the emission limit value (ELV) scenario

3, Kiln 3 gas flow at 477,878 Nm3/hr and associated efficiencies - proposed scenario

A table outlining the benefits of process control optimization (the increase in Kiln 3 gas flow) as summarised h m the FL Smidth report attached is given as follows:

WO 5000 3750

860 855 849

The operation of Kiln 3 at the ELV in the scenario above will not be realised on an mual basis as Irish Cement are obliged to be Compliant with the Kiln 3 gas flow ELV, In such instances Irish Cement operate Kiln 3 below its gas volume flow ELV with a safety margin to maintain compliance. This is the reason for the gas volume in the current scenario above.

As can be seen above the increase in Kiln 3 gas volume to 477,878 Nm3 / hr yields an increase of 1,250 t of clinker per day, which annualised could yield up to an increase of ca. 400,000 tonnes of clinker per year.

The decrease in specific Beat consumption at 5,000 t clinker per 24 hr. compared to 3750 t clinker per 24 hr. is due to the relative reduction in kiln radiation losses at the higher production. The improvement in specific heat consumption is 11 kcall kg clinker or 11,000 kcall t clinker. This equates to a saving of 12.8 kwh / t clinker (1 kcal = 0.00116 kwh). The World Business Council for Sustainable Development (WBCSD) describes in its CO2 protocol that the CO2 per power unit produced externally is 0.43 kg CO2 / kwh. Therefore the energy saving can be also be expressed as a reduction of 5.5 kg of CO2 per tonne of clinker produced at the higher gas volume.

In the context of optimizing the process by increasing Kila 3 gas volume, a review of air emissions w.r.t BAT #19 fiom the Cement BAT conclusions was undertaken.

BAT 19: In order to reduce emissions of NOxfrom the flue-gases of kiln firing and / or reheQting~recalcinati~gprocesses, BAT is to use one or a combination of the following techniques:

a. Process oprirnisation

In the table below the Kiln 3 NOx emission (kg / t clinker) is calculated for the current and proposed scenarios. As can be seen in the table below there is a reduction in the NOx emission rate for the current and proposed gas volumes of the order of 0.0136 Kg NOx / t clinker. Based on this it is expected that similar reductions will be acbieved for other ELVs (particulate, SOx etc.) as shown in the following table.

See Appendix 3 for details of the reduction in emissions of substances emitted.

8.4.4 Planning Permission Status

Irish Cement has obtained a Section 5 notice h m Meath County Council with reference to planning permission for an increase in gas flow at Kiln2, Kiln 3 and Cement Mill 1. The planning permission notice granted by Meath County Council (Appendix 4) determines that increases in gas volume for filn2, Kiln3 and Cement Mill 1 are exempt fiomplaming and as such does not require planning permission. As explained in our additional BAT submission on the 30fh May 2017 last, Irish Cement is seeking to increase the gas flow volume for Kiln 3 only in t h i s BAT C process.

8.4.5 Summary A report has been updated by Dr. Peter Rosholm on behalf of h s h Cement which outlines the improvement in clinker production (1250 clinker tonne per day) and the associated improvement in energy efficiency (1 1 kcal per kg of clinker) that an increase in Kiln 3 gas volume to 477,878 Nm3/hr could achieve.

Maximum rate per hour:

Additionally, it has been demonstrated that with the increase in Kiln 3 gas volume the emission rate of NO, in terms of kg NOx ltclinker is reduced. Based on this similar reductions will be achieved for other ELVs (particulate, SO, etc.) - see Appendix 3. Air dispersion modelling of emissions of NOx and other pollutants at much higher flow rates has been previously submitted.

477,878 N1n3

The air dispersion modelling has shown that Air Quality Standards and Guidelines are easily met in respect of all regulated substances.

PO03045 Irish Cement Ltd Objection to Proposed Determination August 201 7

9 Objection Point No.6: Monitoring of Emissions from Kiln 2 -

9.1 Introduction Irish Cement currently continuously monitors nitrogen oxides (NOx) and particulates in Kiln 2 gases in accordance with its IE licence POO3O-04. It also monitors continuously carbon monoxide (CO) and oxygen (02) in these gases.

Irish Cement was not aware until lSt August 20 17 the full monitoring requirements that wodd be required by the Agency in respect of Kiln 2 gases. In addition to what is currently continuously monitored, the PD requires Irish Cement to monitor continuously sulphur oxides (SOX), hydrogen chloride (HCl), hydrogen fluoride (HF) and ammonia W3).

While the requirement for continuous monitoring of some parameters was known, it would not have made sense to install a Continuous Environmental Monitoring System (CEMS) and later change or upgrade the CEMS to monitor other parameters until the monitoring requirements of PD were known. The correct approach was to do this once when all parameters were identified as having to be continuously monitored,

Once notified, Irish Cement immediately put in place a programme to specify, procure, install and commission the equipment needed to continuously monitor the specified parameters.

Until this equipment is installed, Irish Cement proposes to monitor Kiln 2 gases for SOX, NH3, HC1, HF and TOC periodically (quarterly). Irish Cement notes that BAT5 allows for periodic monitoring of HCl, HF and TOC.

Irish Cement requires an amendment of the PD to permit periodic monitoring of SOX, N H 3 , HCl and HF for a period of 6 months to allow procurement, installation and commissioning of the necessary equipment, the specification of which could not be foreseen.

9.2 Proposed Licence Condition Emission Limit Values and monitoring requirements for Kiln 2 are set out in the PD - Proposed SCHEDULE C: Emissions, Monitoring and Control, C, I Emissions to Air, C. I : I Description, limit values and monitoring at combustion gas emission points reference number: A2-Ul, A2-02, A 2 4 3 and Al-U8 and referenced in Proposed Conditions 1.6,5.1 and 6.4). The licence requires inter aZia continuous monitoring of SOX, N H 3 , HCl and HF.

period of Q12011 to 44 2016 for Emission Points A2-04, A2-05, A2-06, AZO9 and A2- 10, demonstrating compliance with the ELVs in the current licence POO30-04. Licences issued to other cement factories in Ireland have only required periodic monitoring, i.e. annual monitoring. Irish Cement strongly believes that a level playing field should be ensured by not requiring the Platin factory alone to have continuous monitoring of emissions h m non-kiln activities. The cost of providing continuous monitors is significant and as the data provided indicates 111 compliance with Licence POO30-04, it is clear that no further environmental benefit would be achieved by increasing the monitoring frequency on these non-kiln sources. The data as supplied in Appendix 5 confm that there no ELV breaches recorded during the time period of Q l 2011 to 44 2016.

It must also be noted that no complaints have been received during this time period with regards fugitive emissions from these non-lriln activities emission points, showing that an increased frequency of monitoring would not gamer any further environmental benefit to the environs of the site.

Proposed Condition 6.10 of Licence POO30-04 & PD POO30-05 states

“Tlae frequency, methods, scope of monitoring, sampling and analyses LIS set out in this licence, m y be amended with the agreement of the Agency fuZIaving evuiuation of test results ’ I .

With this proposed condition in mind, based on the evidence provided, there is no justification for increasing the frequency of monitoring at these locations when:

1. full compliance has been demonstrated and

2. non-kiln activities emissions have been assessed by the Agency during this time period

Irish Cement could not have anticipated the requirement for continuous monitoring of these emissions, being h m non-kiln activities, as BATC allows for periodic monitoring. Imposition of such an unjustified requirement would result in immediate non-compliance and failure to allow a derogation would be disproportionate and discriminatory.

10.5 Appeal Irish Cement requests that the hquency of monitoring of emissions from emission points Reference Nos A2-01, A2-03, A2-04, A2-05, A2-06, A2-07, A2-09 and A2-10 to be left as at present, i.e. quarterly.

The internal borehole supply fi-om the quarry, which is pumped to a holding tank at ground IeveI (capacity 2,000m3) and thence re-pumped for re-use in the process

In the event of a loss of quarry groundwater supply, a supply is available fiom Drogheda Corporation via a pipeline from Cruicerath.

11.1.2.1 Wastewater

Wastewater effluent h m the facility is not discharged to the public sewer. Wastewater comprises domestic wastewater and utilities wastewater h m laboratories. Wastewater from the works is discharged through a package wastewater treatment package plant and thence in combination with surface and ground water to the common effluent discharge pipe for discharge to the River Nanny.

11.1.2.2 Storm Water

Storm water arises h m rainfall on the site. Rainwater falling on roofs, hard standing and other impervious surfaces is collected by a piping system. Surface water h m the quarry is also pumped to the settlement tanks prior to discharge at SWl/SW4.

Settlement Tank Interceptors are Class 2 except for the Despatch Interceptor and the Garage Interceptor which are Class 1. Within the surface water drainage system there are numerous manholes that act as silt traps.

11.1.2.3 Process Water

Some groundwater fiom the limestone quarry is pumped to the factory to the process water storage tank (capacity 2,000m3). A series of pumps and header tanks are used to distribute this water throughout the process.

Management of process and storm water runoff on-site consists of a water collection system which delivers process and storm water into storm balancing tanks followed by sedimentatiodsettlement tanks, both of which are used to reduce the levels of suspended solids.

In addition, the surface water treatment tanks use floating oil absorbent booms and a fixed total retention boom.

11.1.2.4 Quarry Water (GW1)

Deep well water h m the quarry is managed through continuous pumping of groundwater b m the deep well in the quarry floor. It does not require any treatment.

SW4 discharges to the River Nanny. The River Nanny drains a catchment with an area of 250 km2. The river rises in the east of County Meath before flowing to Duleek to discharge into the Irish Sea at Laytown. The River Boyne drains a catchment nearly 10 times the size of the River Nanny (2,300 kmz). The Boyne rises in counties Offaly and Kildare and drains most of County Meath before flowing through Drogheda to discharge into the Irish Sea at Mornington in County Meath.

The Office of Public Works (OPW) operates a number of gauging stations on both the Rivers Nanny and Boyne. The lowest flow recorded in the River Nanny at M e e k is 0.04 m3/sec or 3,500 m3/day.

According to the EPA a total of 18% of the river channel of the River Nanny was rated as being Class C or Moderately Polluted at that time, with 3% of the channel rated as being Class D - Seriously Polluted. None of the channel length was rated a being Class A [6].

11.4 Discussion Please find attached in Appendix 6 Monthlymeekly Data h m the period of Q120 11 to 44 20 16 for Emission Points S W1, S W3 and S W4, demonstrating compliance with the current licence POO30-04.

As outlined above all water h m Irish Cement Platin is discharged h m site via SW4 to the River Nanny.

Water at SW1 has a retention time of 1 day in the Storm Balancing Tanks and in the Sedimentation Tanks. It has therefore already been subjected to significant balancing so that a 24-hour flow-proportionate composite sample is of no additional value in terms of capturing short-term variations in water quality.

The discharge at SW3 is fbn the Wastewater Treatment Plant (WWTP) and the maximum volume is only a small portion of the maximum total discharge at SW4 (4%). The WWTP contains efnuent balancing tanks which remove the need to take composite samples.

From 201 1- 2016, three weekly BOD results at location SW3, which were reported to the Agency at the time, were slightly above their ELV. This still equates to over 99% compliance for BOD at this monitoring location during this time period, The final discharge at SW4 was not detrimentally affected as the flow from SW3 makes up a fi-action of the final discharge (~0.5%) at SW4 and no issues were noted downstream of the discharge when these results were recorded, in 2012 & 2013.

The flow of water at SW4 is dominated by the flow of s e e water and deep well quarry water (ground water). The total flow at SW4 varies little from day to day

Water discharge at SW4 therefore has already been subjected to significant balancing so that a 24-hour flow-proportionate composite sample is of no additional value b terms of capturing short-term variations in water quality.

It must also be noted that unannounced independent monitoring is carried out by the Agency at least twice per year at SW4. The Agency come to site, take a grab sample at SW4 and monitor for a range of parameters. No compliance issues have been noted over the years 20 1 1 -20 17 in the samples taken by the Agency.

Finally, annually an Independent Ecological Consultant, on behalf of Irish Cement, evaluates the impact of the discharge to the River Nanny. These reports have been assessed by the Agency separately and within this BAT application and it is considered that the discharge is not adversely impacting aquatic ecology within the River Nanny. With this in mind the cost of providing and operating a flow proportional sampler is significant and as the data provided indicates near full compliance with Licence P0030- 04, it is clear that no further environmental benefit would be achieved with the installation and operation of these samplers

Irish Cement could not have anticipated the requirement for 24-hour flow proportionate sampling of these emissions to waters. Imposition of such an unjustified requirement would result in immediate non-compliance and failure to allow a derogation would be disproportionate and discriminatory.

12 Objection Point No 9: Continuous Measurement of pH at SW4

12.1 Introduction SW4 is the ultimate location of discharge of all surface water, quarry water, process water and (treated) wastewater h m the cement factory, SW4 discharges into a long pipe that drains to the River Nanny.

12.2 Proposed Licence Condition Emission Limit Values and monitoring requirements for SW4 are set out in the PD - Proposed SCHEDULE C: Emissions, Monitoring and Control, C.2 Emissions to Water, C.2.3 Description, limit values and monitoring ut emission point reference number SW4.

The proposed monitoring requirements include continuous pH monitoring.

12.3 BAT The BAT Conclusions for the cement industry do not specify any requirements in relation to the Emission Limit Values or monitoring for effluent emanating h m a cement factory. IED Article 46 with Annex VI Part 5 sets Emission Limit Values for discharges of waste water from the cleaning of waste gases, but no general ELVs for pollution. The Irish Cement plants do not generate waste water h m the cleaning of waste gases.

12.4 Discussion currently pH is monitored monthly as required by IE Licence Register No POO30-04. The results of pH monitoring are reported in the Annual hvironmental Report. Figure 1 shows the monthly values of pH for the years 20 10- 17

The results show that excursions of pH outside the licence limits (6-9 pH units) do not occur. The reason is that water discharged h m SW4 is predominantly quarry water and is unpolluted.

Irish Cement could not have anticipated the requirement for continuous monitoring of pH in SW4. Imposition of such an unjustified requirement would result in immediate non- compliance and failure to allow a derogation would be disproportionate and discriminatory.

Objection Point No 10: Derogation for Dormant Plant

13.1 Introduction In the Inspector’s Report reference is made in the Table 2: Summarv of submissions in Section 5 under “Issues Raised”:

Recommendation that a BAT licence review is carried out for all dormant sources of emission when they recommence operation and emission limits are monitored to enszsre compliance with BAT emission limit values,

The Inspector’s Report comments:

The dormant emission points will be monitored whenever they come back into operation and are liable to the stipulated emission limit values in the RD.

13.2 Proposed Licence Condition No provision is made for time to comply when dormant emission points are brought back into service.

13.3 BAT Article 15(4) of Directive 2010/75/EU provides for derogations fi-om the requirement laid down in Article 15(3) where the costs associated with the achievement of the emission levels associated with the BAT disproportionately outweigh the environmental benefits due to the geographical location, the local environmental conditions or the technical characteristics of the installation concerned.

13.4 Discussion Section 86A requires the EPA to apply BATC, but seem to allow it to deviate from BATC if it can apply other limits that will give an equivalent degree of environmental protection/ S.86A also restates Article 15(4) of the IED re “derogations fkom the requirement laid down in Article 15(3) only where the costs associated with the achievement of the emission levels associated with the BAT disproportionately outweigh the environmental benefits due to the geographical location, the local environmental conditions or the technical characteristics of the installation concerned.”

IE Application - Attachment A - A . 9. Derogation under Section 86A(6) states:

The following sources have been idle or in limited use over the past number of years, therefore no recent monitoring results are available for these sources.

However, in order to prove conclusively and to determine whether any upgrading of equipment is required when this equipment is restarted, ICL propose to monitor emissions and compare the values to the BAT emission limit values.

If any of the above sources cannot comply with BAT emission limit values when in 111 operation, a planned prshgamme of improvement towards meeting the limits will be submitted to the Agency. Irish Cement propose to include in its Environmental Management Plan an assessment of the means necessary to enable the BAT ELVs to be met and a realistic programme to achieve this. A derogation of 18 months h m the recommencement of operations of each individual source would be needed to implement these programmes.

Air dispersion modelling of emissions of particulates h m these sources at the current ELVS (POO30-04) has shown that air quality standards are complied with and that there is no s igdcant adverse impact on the air quality in the vicinity of the cement works. In view of the technical characteristics of the equipment it would be disproportionately expensive to carry out any upgrade work unless there is a clear need to protect the environment in the vicinity of the cement works.

13.5 Appeal Irish cement requests that the licence allows a derogation of 18 months for Irish Cement to achieve compliance with the ELVs specified in the proposed determination as they are lower than those in the current licence Register Reference POO30-04.

Coal mlll monitorlng in cement operations

Dlrect dial -220

ClatEl 17 July 201 7

Dear Mr Breen,

Please find enclosed comments to your query regardlng coal mill monltorlng In cement operations.

We can confirm that in Germany there are coal mills in operation that use kiln exhaust gas and have a separate coal mill stack. In these instances dust and oxygen are measured continuously. All the other parameters (NO, SO,, HCI, HF, TOC, NHs) are measured periodically (3 times per year) in the coal mill stack.

The reason for spot or periodic measurements in the coal mill stack is that the kiln exhaust gas used in the coal mill has almady been monitored in the kiln Staek.

We trust this clarifies your query.

Yours sincemly,

Merno-93/Platin/PH gas flow in Stack/PRos/20l7/05/25 - revised 2017.08.04

Production simulatlon at 3750,4250 and 5000 tpd clinker - estimation of PH exit

gas in stack expressed as Nm3/h (dry) gas 0 10% Oz.

Kiln 3 a t Irish Cement Platin works is currently proaucing around 3750 tpd clinker with less than 410000 Nm3 (dry)/h@lOo/o 0 2 preheater exit gas in the stack. Due to increased market demand Irish cement is con- sidering increasing the production capacity of kiln 3 a t Platin Cement works. The maxlmum achievable production capacity is evaluated to be around 5000 tpd clinker.

The operational parameters of kiln 3 a t Platin Cement work have been simulated at 3 different production levels for worst case fuel scenario. The simulations are shown in:

Enclosure 1: simulation of the Operational parameters a t a production capacity of 3750 tpd clinker.

1 Enclosure 2: Simulation of the operational parameters at a production capacity of 5000 tpd clinker.

. Enclosure 2: Slrnulation of the operational parameters a t a production capacity of 4250 tpd clinker.

3750 tad clinker (enclosure 1)

The simulation shows a specific heat consumption on 860 kcaI/kg clinker.

The preheater exit gas is simulated to 2.498 kg gas/kg clinker with a density of 1.352 kg/Nm3 corresponding to 1.848 Nm3 (wet) gas/kg clinker with a moisture content of 0,110 kg H20/kg dry gas.

The amount of dry preheater gas is calculated as 2.498/1.11 = 2.250 kg dry gas/kg clinker.

The amount of moisture in the preheater exit gas is calculated to 2.498- 2.250=0.248 kg H20/kg clinker or 0.310 Mrn3/kg clinker and the volume

The simulation shows a specific heat consumption on 849 kcaI/kg clinker.

The decrease in specific heat consumption at 5000 tpd clinker compared to a t 3750 tpd clinker is due to the relative reduction in kiln radiation losses a t the higher production.

The preheater exit gas is simulated to 2.471 kg gas/kg clinker with a density of 1.353 kg/Nm3 corresponding to 1.826 Nm3 (wet) gas/kg clinker with a moisture content of 0.11 kg H20/kg dry gas.

The amount of dry preheater gas is calculated as 2.471/1.11 = 2.226 kg dry gas/kg clinker.

The amount of moisture in the preheater exit gas is calculated to 2.471- 2.226=0.245 kg H20/kg clinker or 0.306 Nm3/kg clinker and the volume of dry preheater gas is calculated to 1.826 - 0.306=1.520 Nm3 dry gas/kg clinker with 4.4% 02, 28.0% COz and 67.6% Nz.

The 1.520 Nm3/kg clinker (dry) preheater exit gas at 4.3% O2 is con- verted to lO0/o O2 by 1.520*(1+ (10-4.4)/ (21-10)) = 2.294 Nm3/kg clinker dry gas @ 10%02.

The predicted preheater exit gas flow a t 5000 tpd clinker is 5000/24ton/h*1000kg/ton*2.294 Nm3/kg clinker dry gas @ 10% O2 477878 Nm3/h dry gas 8 10% 02

Dear Mr. Breen, Weare in receiptofthe attached confirmation from Meath County Council, the planningauthotity, which states by means of a Section 5 Declaration under the Planning and Development Act 2000, as amended, that the proposed increase in Volumetric Flow Rate via licenced emission points (stacks) on Kiln 2, on Kiln 3 and on Cement Mill Building 1 i s EXEMPTdevelopment.

Therefore, the proposed increase in volumetric flow rates does not fa l l within a class of development requiring planning permission.

Yours since re I y,

n/a

In pursuam of the powers conferred upon them by the Planning and Development Act 2000, Meath County Council has by order dated 0 7 . 0 3. zO/7 decided to Declare the proposed development is EXEMPT, in accordance with the documents submitted namely: As part of an existing EPA Licence review, Irish Cement Ltd. is seeking an increase in the existing volumetric air flow rate limit at three of its EPA licenced emission sources. This air low is abated using various filters & abatement measure8 prior to discharge via emission points or stacks. No new buildings, structures, or plant are proposed & the change in volumetric flow rate does not change the cement manufacturing process or output & therefore we request that the planuing authority declare that the change in volumetric air flow rate as outlined is not development & does not require planning permission. The volumetric air flow rate at Plath Cement Works is governed by the exhting Industrial Emissions Licence (IE P0030-04)& monitored by the Environmental Protection Agency (EFA). This is also currently under review by the EPA in order to introduce the recommendations for revised environmental controls as set out in the EU publication Best Available Techniques Reference Document for the production of cement (BAT C) at Phtin Cement Works Platin Co. Meath.
