Call for tender for field validation tests, controlled release, for data evaluation and

for a project coordinator for the development of standardized method to determine fugitive

and diffuse emissions of volatile organic compounds into the atmosphere

Launch: 2015-10-02 Deadline for tenders: 2015-11-09 I Introduction I.1 General The following project requires the development and validation of standardized test methods and is subject of this call for tender:

• Elaboration of a European Standard "Stationary source emissions — Standard method to determine fugitive and diffuse emissions of volatile organic compounds into the atmosphere"

For this project several networks, institutes, laboratories and a project coordinator will be contracted. They will cooperate in the development and validation of the required test method(s). I.2 Context The European Commission’s standardisation mandate M/514 under the Directive 2010/75/EU on industrial emissions, has been accepted by CEN/BT, and a decision has been taken to establish this standardisation work within CEN/TC 264/WG 38. The control of the emissions of VOCs to atmosphere due to their losses during storage or transport is covered by both EU legislation and international protocols. The legislation on industrial emissions (Directive 2010/75/EU) is supported by the Best Available Techniques Reference documents (BREFs), which set out at an EU level the best available techniques for defined industrial activities and/or across these activities. Several BREFs also cover the prevention and control of fugitive and diffuse emissions of VOCs from industrial storage and transfer activities, in particular the BREFs concerned with mineral oil and gas refineries, large volume organic chemicals, and the “horizontal” BREF on the emissions from storage. The mandate for this work requests the European standardisation organisations to develop a European Standard that can be used in the determination of VOC emissions to be regulated within permits that are issued according to the Directive. Total VOC emissions are also regulated at the EU and Member States levels under the National Emission Ceilings Directive (2001/81/EC) which sets total emission ceilings for such emissions at specific levels to be met from 2010 onwards. VOCs are emitted by a wide range of sources including transport and industrial processes, as well as biogenic and other natural sources, and also by associated storage and handling activities, and the industrial and domestic use of VOC containing products. VOCs are emitted to a significant extent by fugitive and diffuse sources (including non-point sources), although this is difficult to quantify accurately. (Note: For the purposes of the mandate the definitions of fugitive emissions and diffuse emissions given in Refs. 1 and 1a in Annex 1 apply).This requirement for more accurate determination of these important VOC emissions creates a challenge because of their area emissions, and they require specific measurement and estimation methods that are currently not standardised. However, improving the accuracy of determining these VOC emissions should enable an improved assessment of these losses, and may provide an incentive to reduce such

2

losses, as well as the benefits to their effects on the environment and human health. This should also contribute to the more uniform application of EU regulations and EU guidance documents. I.3 New standard monitoring fugitive and diffuse sources I.3.1 General The European Commission has requested the development and validation of a European Standard that can be used for the determination of fugitive and diffuse emissions of VOCs to the atmosphere from certain industrial sectors. The types of VOCs and the industrial sectors that are to be covered are summarised below. The scope of the standard, and the strategy for its implementation, are also summarised below in this Section. I.3.2 Definition of VOCs The definition of a VOC as given in Directive 2010/75/EC shall be used: “Organic compound” shall mean any compound containing at least the element carbon and one or more atoms of hydrogen, halogens, oxygen, sulphur, phosphorous, silicon or nitrogen, with the exception of carbon oxides and inorganic carbonates and bicarbonates. “Volatile organic compound (VOC)” shall mean any organic compound having a vapour pressure of 0.01 kPa or more at 293.15 K, or having the corresponding volatility under the conditions of use. For the purpose of this EU standard also the fraction of creosote, and similar substances, that exceed this value of vapour pressure at 293.15 K shall be considered as a VOC. I.3.3 Industrial sectors and types of emission sources covered by the standard The industrial sectors and the types of emission sources to be covered in this standard are given in Mandate M/514. They are also reiterated in Annex 2 of this document for completeness, in order to explain this proposal for the validation work programme. The standard is required to support legislation as given in Section I.2 above and in Annex 1. The standard shall be validated in the field using representative industrial sites that are encompassed by the Mandate M/514, and using suitable sources that are present in these, using as applicable, the monitoring methods and the estimation and calculation procedures, as set out below. I.3.4 Applicable monitoring and estimation methods to be considered in the standard The monitoring and estimation methods that are covered by this standard, most of which are those that are also addressed in the relevant BREF documents: (i) Optical gas imaging (OGI) method that uses a hand-held infrared camera for the identification of

point source leaks; (ii) Differential absorption lidar (DIAL) method that operates in the infrared and ultraviolet spectral

region using laser sources for the detection and quantification of fugitive and diffuse emissions of the specified VOCs and their fluxes;

(iii) Solar occultation flux (SOF) method that monitors solar radiation in a broad spectral region for the detection and quantification of fugitive and diffuse emissions of the specified VOCs and their fluxes; It should be noted that the SOF technique uses direct solar radiation to sense the absorption spectrum of the emitted VOCs downwind from the source, and this imposes requirements both for the sun to be shining and for the sun to be in the correct orientation with respect to the wind direction and the industrial plant.

(iv) Calculation/estimation methods using industry standard, or site specific, fugitive emission factors for each type of component.

(v) Tracer techniques for quantification of identified leaks. Items (i) to (iv) specify the methods that are included in BREF (Ref.1a). Item (v) is mentioned in this BREF (Ref.1a, p. 232) and it is listed as an additional method which was identified as relevant by CEN/TC 264/WG 38. Other monitoring and estimation methods may be applied once they are demonstrated to have equivalent performances. Their role is also specified in general terms in the BREF (Ref.1a), Section 3.26.1.3, p. 232

II Objectives

3

Mandate M/514 requires CEN to prepare and validate a standard for the determination of diffuse and fugitive emissions from oil and gas facilities. It should be complementary to the existing standard for the determination of leaks from piping and equipment EN 15446:2008.

Validation will cover techniques which are regarded under the EU Commission's BAT Conclusions - 2014/738/EU: Commission Implementing Decision of 9 October 2014 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for the refining of mineral oil and gas, and additional techniques included by CEN/TC 264/WG 38 (listed above).

Two validation studies will be undertaken.

The first will use a controlled release, able to replicate typical industrial emission levels, at an industrial location to challenge the remote sensing techniques with a known release of VOC under typical industrial conditions.

A second validation study will deploy the suite of techniques at an industrial facility to validate the combined framework of techniques defined in the standard and demonstrate their operation at a typical site.

The programme of validation work that is required for the development of the standard is constituted of a number of work packages that are given below in this Section. These shall take account of the overview given in Section I.3 above. The associated deliverables are also summarised in each work package below. The necessary costs and time schedules for these are given in Sections III.10 and III.11, respectively. III Execution The execution of the mandate will be divided into several work packages. VDI/DIN will carry out the procedural work and sign the contracts with the selected subcontractors following authorization by EC.

All successful contractors will be required to join WG 38, and will be expected to actively take part in the meetings and discussions of WG 38 and to contribute to the development of the standard.

III.1 Work package 1 (one contract): Research into performance of monitoring techniques Task 1.1: Collation and review of available technical information and stakeholder consultations This Task will entail:

• Collation and review of technical information collected during previous and current field work using the techniques listed in Section I.3.4 above, with a view to defining an appropriate field validation programme;

• Consultation with the stakeholders with a view to finalising the scope and methodology of the field validation programme, and of the standard.

Deliverable 1a: A report covering a review of the available monitoring techniques, examples of field measurement data, recommendations for the future together with a comprehensive set of references to the available field work. Task 1.2: Specifications for the initial performance requirements of the remote monitoring methods In collaboration with WG 38 the initial performance requirements of the remote monitoring methods will be specified based on the review of the previous and current field work (WP1a) that has used these measurement techniques. This will enable the first field test programme to be planned efficiently (see WPs 2 & 5). These initial performance requirements will be reviewed and agreed by WG 38. These requirements will be reported. Deliverable 1b: Report on the required performance characteristics of the remote monitoring techniques, following review by the CEN Working Group.

III.2 Work Package 2 (one contract): Planning and coordination of the field measurement programme General A single contractor is required to coordinate the validation work programme – WPs 3, 4, 5 and 6. This WP 2 is divided into 3 related Tasks. The project coordinator appointed under WP 2 will be responsible for the planning and coordination of the two field validation exercises detailed in this call for tender. A key responsibility will be the selection of suitable industrial sites for this validation programme. This will require a knowledge of the sites and their availability and processing complexity, and for example, whether there is a LDAR programme in place. A short list of potential sites should be prepared for WG 38 in order to enable a decision on the most appropriate industrial site to be selected. This work will also require negotiations with the industrial site operators. The tasks of liaising with the organisations involved with the screening and monitoring methods at these industrial sites will also require a clear overview of the estimation/calculation and monitoring methods used, their advantages and limitations, and the requirements for supplementary data etc. These tasks would therefore be optimally carried out by an organisation that has the expertise to act as the coordinator of the field measurements, and to provide advice on relevant field measurement tasks specified below. The objective should ensure that the field work programme operates as seamlessly and efficiently as possible within the three tasks given in this work package: Task 1: Initial consultation with suitable candidate industrial site operators, and planning It is expected that the coordinator proposed for this work will be named in the Tender.

• Generation, in collaboration with WG38, of selection criteria for sites for the two campaigns. • Selection of a candidate list of potential sites who would in principle be prepared to host either

of the validation studies. • Identification of any operating LDAR programmes at the candidate field test sites as far as

practical, where the sites have active emissions • It is expected that the coordinator (or designated representative) will be present at both the

validation trials. • Where there is an LDAR programme in place the field coordinator should review of the use of

the monitoring equipment and its calibrations. It is important that the status and the results of the LDAR programme(s) are made available to WG 38 for review prior to any field tests being carried out using the remote sensing techniques.

• Taking account of the deliverable(s) and conclusions from WP 1; • Providing guidance and inputs to ensure that valid conclusions are drawn from the results

obtained; • Checking the technical reporting of the various work packages and the conclusions drawn; • Attending WG 38 meetings, where the decisions of this task must be agreed wherever

possible, and progress presented. Deliverable 2a: Coordinator appointed for the field measurement programme Deliverable 2b: Short list of candidate site(s) for the two validation studies identified, which will be reviewed by the CEN Working Group Deliverable 2c: Participation in, and discussions at, CEN/TC 264/WG 38 meetings Task 2: Support for the first field validation programme (controlled release at an industrial site) The primary objective of the first validation programme will be to measure controlled releases of selected VOC(s) at an industrial location. This will enable an assessment of the comparability and provide information on the accuracies of the measurement techniques. It is expected that the controlled release will be of a representative VOC such as propane.

5

This task will require the contractor (coordinator) to select (in collaboration with WG 38) a site with suitable characteristics so as to be able to host a controlled release facility. These characteristics should cover replicating as far as practical a typical environment typical of the industrial areas (storage/process areas/VOC handling) covered by the European Standard being validated within this programme. This may not be a fully active site but it should have:

• Scope for the deployment of the selected controlled release equipment and the selected measurement techniques at suitable locations within it. The site must be able to allow the release of controlled amounts of VOC(s) that will be used to test the proposed measurement methods. A suitable area would be a disused or decommissioned part of a site with no active VOC handling and/or storage. The whole area should be flat for roughly 500 m x 500 m to allow deployment of the various techniques.

• The site should preferably also have some limited area with fugitive and/or diffuse emissions within the scope of this standard, in an area where the remote monitoring methods can also be inter-compared to demonstrate their comparability and accuracy. This may entail an active VOC handling or storage area with existing VOC emissions estimation, to allow a small scale validation of the techniques for measuring real fugitive/diffuse emissions.

• Preferably also with a LDAR or VOC emissions programme (to be discussed with WG 38) with results that have demonstrated credibility.

• It should also have suitable locations to deploy the meteorological equipment that is being defined within the validation programme, in order to provide a first assessment of its capabilities.

• Willing and able to host the validation studies within the scope and timetable agreed by WG 38.

• Preferably an industrial site with relatively simple emission sources so that the results from the controlled release comparisons and from the selected site emissions, during this first field trial are unambiguous.

The coordinator should facilitate negotiations with the site to enable the testing programme to be carried out. The decision on the selection of the first field trial will be made in collaboration with WG 38 and will take account of the initial specifications drawn up for the performance requirements of the remote monitoring methods. Together with WG 38, the selected site, and the selected providers of the controlled release and measurement techniques, the coordinator will draw up a test plan for the first validation study. This will define the number and range of the controlled releases. It is anticipated that the study will be designed to enable, where possible, the assessment of the performance of the monitoring techniques with respect to:

• the distance downwind the measurements are made • configuration of the emission sources (number, size, and elevation)

It should also be designed to investigate the:

• limit of detection of the techniques • effect of complex environment on the accuracy of the determined fluxes • effect of technique specific confounding issues that may be proposed by WG 38

The coordinator will provide support and coordinate the activities during the validation study. The validation work at the selected industrial site should also take account, where possible, of any relevant use of industry or other state-of-the-art technical procedures, and other direct or indirect measurement techniques at that site; The relevant advantages and limitations of the identified suitable first site(s) will be prepared and presented to the CEN Working Group for their decision on which is the most suitable. Deliverable 2d: First industrial site selected that can be used with a known concentration controlled

VOC release facility; Report on decisions of this Task and the rationale for arriving at these

Deliverable 2e: Work plan for the first validation study Deliverable 2f: Coordinator provides guidance and inputs to the field measurements

6

Deliverable 2g: Coordinator provides review of reports of the field measurements and conclusions drawn

Task 3: Support for the second field validation programme (application of the techniques at an industrial site) A second field trial is required where there are active emissions to atmosphere, and relatively complex industrial operating processes. The objectives of the second validation study are to:

• Assess the scope of VOCs that would be addressed by this field trial to assess the breadth of future applications.

• Establish how the estimation, calculation, and the monitoring procedures defined at this time may be applied to these different complex scenarios.

• Test the validity of any conclusions drawn to date from the first field trial and from the previous work packages 1, 2, 3 & 4.

• Provide comprehensive and effective inputs to the standard from this validation process. This task will require the contractor to identify (in collaboration with WG 38) a site taking account of the following requirements:

• LDAR programme in place and well established, with results that have credibility and that may be assessed beforehand by the WG38.

• Results of any previous studies using the OGI technique or other remote sensing techniques. • Accessible to the remote monitoring methods - This issue of accessibility needs to be defined

in more detail by the relevant experts within the WG 38. • Willing and able to host the validation studies within the scope and timetable agreed by

WG 38. • Scope for the implementation of a suitably specified optical gas imaging camera during the

remote monitoring field trial, and work programme defined and implemented (see WP 4.4). • Possible supplementary data is available, (e.g. appropriate meteorological monitoring, passive

sampling, canisters for speciated VOC sampling), or locations exist in the industrial site where these can be effectively installed.

• Consideration should be given to the use of tracer techniques where these are judged to be beneficial to the objectives of the validation programme.

• Confirmation that the meteorological monitoring that is carried out during the field measurement trials by the participating scientific teams is calibrated satisfactorily, and is implemented correctly and comprehensively enough to obtain the required wind speed and directional data, with suitable vertical and horizontal (if appropriate) profiling over all the areas where the measurement scans will take place.

• Implementation of passive and/or canister sampling to support the remote monitoring data during the trial if practical.

The relevant advantages and limitations of the identified suitable first site(s) will be prepared and presented to WG 38 for their decision on which is the most suitable. The decision on the selection of the second field trial at an industrial site will be made in collaboration with WG 38 take account of the specifications drawn up for the performance requirements of the remote monitoring methods together with any modifications to these that have been learnt from the first field validation trial (Task 2). The coordinator should facilitate negotiations with the site to enable the testing programme to be carried out. Together with WG 38, the selected site, and the selected providers of the measurement techniques, the coordinator will draw up a test plan for the second validation study. The coordinator will provide support and coordinate the activities during the validation study. The validation work at the selected industrial site should also take account, where possible, of any relevant use of industry or other state-of-the-art technical procedures, and other direct or indirect measurement techniques at that site; The coordinator should facilitate negotiations with the site to enable the testing programme to be carried out. The validation work programme at the identified industrial site should also take account of the relevant use of industry or other state-of-the-art technical procedures, and other direct or indirect measurement techniques that may be applied;

The relevant advantages and limitations of the identified suitable industrial sites will be prepared, and presented to WG 38 at meeting(s) for their decision on which is the most suitable. Deliverable 2h: Second industrial site selected; Report on decisions of this Task, and the rationale

for arriving at these Deliverable 2i: Work plan for the second validation study Deliverable 2j: Coordinator provides guidance and inputs to the field measurements at the second

industrial site Deliverable 2k: Coordinator provides review of reports of the field measurements and conclusions

drawn from the second measurement trial III.3 Work Package 3 (one contract): Specification of meteorological measurements (with wind speed and direction) Meteorological measurements are required to be carried out during field trials to derive wind speed (and direction) profiles in a vertical plane. These profiles are combined with concentration measurements obtained with the remote monitoring methods to obtain mass fluxes. In order to construct a wind speed profile with a logarithmic profile at least two wind sensors must be deployed at different elevations. However, this is only valid in a flat terrain with no complex topographical structures. For this validation work, it is required to deploy at least four meteorological sensors at different elevations (up to 15 m) due to the topography of the industrial site, and at different locations covering different site areas. The required sensor characteristics must be:

• Calibrated to a traceable standard; • Accuracy of 0.1 m/s at around wind speeds up to 10 m/s; • Deployed at different elevations of up to 15 metres above the ground.

A portable wind LIDAR to determine a vertical profile in the 20 – 200 m range should also be applied. The LIDAR wind data combined with the meteorological sensors deployed at different elevations will allow more accurate vertical speed wind profiling to be derived in the 0 – 200 m range, including in atypical meteorological and topographical situations, and these techniques together will provide improved validation of the wind profiles being used. In addition, there are important requirements during these validation field trials for specific atmospheric sensing measurements to more fully quantify the atmospheric conditions, involving:

• Solar insolation/solar radiation present during the field campaigns; • Temperature and pressure present during the field campaigns; • Any stratification of the atmosphere in regions where the emitted industrial plumes are

monitored. The combination of the above meteorological results will be necessary to provide a valid interpretation and analysis of the monitoring results obtained, and thus to provide inputs to the formulation of the European Standard, and to provide support for its validity when published. It is not expected that all these meteorological measurements will be required in the Standard but these measurements carried out during the validation programme will enable the minimum meteorological measurements to be specified in the Standard that ensure the validity of the results obtained when it is applied in future. Improvements to the measured results in terms of their measurement uncertainties and other factors will be assessed for each of these meteorological measurement systems. The wind LIDAR should be deployed during the two validation studies to provide additional wind data to support the validation exercises. Deliverable 3a: Specifications provided for the number of sensors and deployment locations required

in consultation with WG 38 Deliverable 3b: Specifications for a portable wind LIDAR Deliverable 3c: Deployment of additional meteorological measurements during validation studies; data

sets provided to WG 38 III.4 Work Package 4 (one contract): Optical gas imaging camera

8

It is recognised that optical gas imaging cameras are specified within the BREF for Refining Mineral Oil and Gas (Ref.1a). WG 38 accepts the applicability and limitations on these. An optical gas imaging camera will be selected from those available – with the most suitable performance characteristics, including the most appropriate spectral wavelengths for the selected VOC to be monitored at the industrial sites, and the required plume detection capabilities in the industrial environments. Specifications for the optical gas imaging camera will be prepared, including requirements for the validation of the method. This will be implemented at the selected sites during the two validation studies to identify significant emission sources and validate the methodology developed within WG 38. Deliverable 4a: Specifications of the optical gas imaging camera competed, with validation

requirements Deliverable 4b: Report on the results of this work package and application of the OGI at the selected

sites III.5 Work Package 5 (four contracts): Implementation of the remote monitoring methods at a site where a controlled emission source of VOCs can be located and operated in the field. A validation work programme for the remote monitoring methods at the first selected validation site will be specified from the outputs of the work packages 1 – 4 above. Contracts will be let for delivery of each of the techniques to be validated – DIAL, SOF, Tracer and the controlled release. Tenders will be accepted for one or more of these activities. The activities under this WP will include: 1. Visit to the industrial site by qualified scientists, and discussions with the plant owners, to ensure

that the defined validation work programme is practical and achievable during the selected times and within the allocated time scale.

2. Identification of the location to be used for the controlled release source, with suitable access for the measurement systems to be used and finalisation of the validation work programme in collaboration with WP 2, Task 2.

3. Deployment of a controlled release facility in the open environment to simulate VOC emissions. The controlled release facility should be able to: • Simulate emissions with typical spatial distribution of leaks from industrial plant – i.e. ability to

simulate multiple release points at the same time. • Able to release VOC(s) suitable for testing the remote monitoring methods with release rates

up to ~ 50 kg/hr (propane equivalent) and controllable down to ~ 5 kg/hr with known release rates. It is expected that the release will consist of propane, however the exact release characteristics will be agreed between the WG, the campaign coordinator and the contractor responsible for the controlled release.

• Able to deliver emissions at these rates for periods of at least 1 hour. • Calibration of the release rates.

4. It is anticipated the measurement of the controlled release will take place over a period of 3 – 4 days with a number of controlled releases each day (at least 5 per day);

5. Deployment of the meteorological equipment at suitable location(s). It is anticipated that the different techniques will utilise their own meteorological measurements where these form a part of the usual deployment of the technique. Additional meteorological measurements to aid the validation of these will be provided under WP 3

6. Implementation of the validation work programme including measurement of the controlled releases by DIAL, SOF and Tracer techniques.

7. Where possible within the period of the validation study consideration should be given to the measurement of identified and separable emissions sources from the site where this would add value to this first phase of the validation.

8. Possible requirement for linking the measurements with the estimation methods and the data required from the plant operator, if these estimation methods are available.

9. Possible requirement for linked OGI monitoring delivered under WP 4, and/or other technologies, to be decided and work programme defined.

10. Possible requirements for any supplementary measurements. 11. Completion of the monitoring exercise at the first industrial site using the monitoring technqiues

deployed. 12. It is anticipated that the complete field campaign will have a duration of one to two weeks.

13. Data processing and reporting of the results by the organisations that have been contracted to carry out the monitoring in the field. The results of the comparative evaluation(s) will be included in this.

14. Conclusions drawn from the first field trial. For each VOC monitoring technique and the controlled release the following deliverables are expected. Deliverable 5a: Scoping visit to selected site completed with location of the controlled emission source

agreed and area of the site to be monitored agreed Deliverable 5b: Completion of the monitoring exercise at the first site Deliverable 5c: Data processing of the results and report completed, with conclusions. Data sets

A validation work programme for the remote monitoring methods at this second complex industrial site should be specified from the outputs of the WPs 1 – 5 above. The industrial site should be selected to be as representative as possible to meet the scope of the industries and the VOCs addressed by this European Standard, and relevant to the performance capabilities of the measurement techniques. The work delivered in this WP will include: 1. Visit to the industrial site by qualified scientists, and discussions with the plant operators, to

ensure that the validation work programme is practical and achievable during the selected times within the allocated time scale.

2. Finalisation of the validation work programme including a. Specification of the areas of the industrial site to be selected and monitored, and the duration

of the measurements, for each type of remote monitoring method. The areas to be covered should preferably be such that a valid measurement of the total fluxes of emissions from the complete industrial plant is achievable.

b. Requirement for linking these with the estimation methods and the data required from the plant operator is essential.

c. Requirement for linked OGI monitoring, and/or other technologies, to be confirmed. d. Possible requirements for the supplementary measurements at the second industrial site. This will be carried out in conjunction with WP 2, Task 3.

3. Deployment of the meteorological equipment at suitable location(s). It is anticipated that the different techniques will utilise their own meteorological measurements where these form a part of the usual deployment of the technique. Additional meteorological measurements to aid the validation of these will be provided under WP 3.

4. Completion of the monitoring exercise at this second industrial site implementing the validation work programme, using SOF DIAL and Tracer techniques, and the OGI technique (delivered under WP4) where required.

5. It is anticipated that this second field campaign will have a duration of approximately three weeks. 6. Data processing and reporting of the results by the monitoring organisations concerned, together

with the results of any comparative evaluation(s), together with the implications to the European Standard from the field trial.

7. Comprehensive conclusions drawn from this field trial. For each VOC monitoring technique (DIAL, SOF, Tracer) the following deliverables are expected. Deliverable 6a: Scoping visit to selected industrial site completed with parts of the site to be monitored

agreed Deliverable 6b: Completion of the monitoring exercise at the second industrial site Deliverable 6c: Data processing of the results and report completed, with conclusions; data sets

provided to WG 38 III.7 Work Package 7 (one contract): Synthesis and statistical evaluation of the monitoring data available after the field trials

10

This work package is required to bring together the results of all of the previous work packages in order to ensure that all the results are comparable and synergistic with each other, and also to maximise the conclusions that can be drawn – to provide the optimum inputs to the standard being drafted. The results of the above work packages are reports which may not comprehensively take account of the other work packages carried out. This work package aims to synthesise the results of the individual work packages and draw conclusions. The data sets will include: 1. Results from available LDAR programmes at the two industrial sites. 2. The screening data obtained from OGI field testing, and the lessons learnt from the OGI

methodologies applied in practice at industrial sites in the EU. 3. The results obtained from the DIAL field tests, the advantages and the limitations of the technique

learnt, and their comparison(s) with the other monitoring technique made and comparisons with the LDAR and the OGI screening results: These comparisons will also feed into work package 8 below to provide specifications of the performance of the techniques, and the evaluation of its measurement uncertainties in different industrial scenarios.

4. The results obtained from the SOF field tests, the advantages and the limitations of the technique learnt, and their comparison(s) with the other monitoring technique made, and comparisons with the LDAR and the OGI screening results; These comparisons will also feed into the work package 8 below providing specifications of the performance of the technique, and the evaluation of its measurement uncertainties in different scenarios.

5. The results obtained from the tracer technique, the advantages and the limitations of the technique learnt, and their comparison(s) with the other monitoring technique made, and comparison with the LDAR and the OGI screening results. These comparisons will also feed into the work package 8 below providing specifications of the performance of the technique, and the evaluation of its measurement uncertainties in different scenarios.

6. Data on the controlled releases carried out in the first validation study. 7. Information on the site operations and any knowledge on the estimated emissions during the

period of the measurements for Sites 1 and 2 8. Additional meteorological data as described in WP 3 Tasks will include:

• Drawing together and summarising the results in the above data sets. • Comparisons of all the results and conclusions with those derived from work package 1,

covering prior information and stakeholder views. • Statistical assessment of the performance of the techniques.

The outputs from this work package should be a suite of comprehensive and valid conclusions and recommendations that shall presented to WG 38 to feed into the development of the standard, Deliverable 7a: Statistical analysis of the data sets, with conclusions on the performance of the

techniques; data presented to WG38. Deliverable 7b: Report on comparisons of all the results and conclusions with proposals for

consequences and inputs to the European Standard. III.8 Work Package 8 (one contract): Develop specifications of the performance requirements for remote monitoring methods for use with the standard The initial performance requirements of the remote monitoring methods that are employed in this validation programme (e.g. DIAL and SOF) are derived in WP 1b above. Work package 8 specifies and provides the performance specifications that should be incorporated into the European Standard – in order to define those specific methods and their correct implementation that are suitable to be used in the future implementation of the published standard. This work will entail taking the initial specifications of WP3, and the outcomes, the recommendations, and the conclusions, of the validation work from the field measurements in WPs 1 – 7, and bringing these together to provide comprehensive performance specifications for the DIAL, the SOF, and any other relevant methods. This should be designed to enable these techniques to be used robustly for the purposes of implementing this standard in the future, at different industrial sites, and addressing the different VOC species covered by the standard.

11

Specified test methods shall also be included that can be used to demonstrate that these performance specifications are met in all on-going field tests that are carried out within the scope of the standard, as far as practical. This work package shall also be used to specify suitable on-going quality assurance and quality control checks that should be applied to these monitoring techniques. The work package shall also contain guidance on which VOCs and which industrial processes will be difficult to address with these optical monitoring techniques This work package shall also provide an evaluation of the measurement uncertainties that should be achievable with these specified monitoring methods, derived using the comprehensive performance specifications of this work package, derived from the outcomes of the field tests, and derived from the test methods that are given to confirm their on-going performance. Deliverable 8: Report defining comprehensive specifications of the performance requirements for the

remote monitoring methods for use with this European Standard. III.9 Work Package 9 (one contract): Develop specifications of the performance requirements for remote monitoring methods for use with the standard This work package covers the reporting of the work to address the timetable for the execution of the mandate (Section 6) and the deliverables are as follows: 1. Interim month 12 report following the implementation of the mandate covering the analysis of the

applicability of the selected methods for monitoring the different fugitive and diffuse emission sources, and a definition of the optimum field validation programme.

2. Interim month 24 report covering: • The completion of the first field validation programme and its results and conclusions, • Status of the second field validation programme, and progress with its results and conclusions, • Summary of progress with the drafting of the European Standard.

Annex 2: Industrial sectors and emission sources to be covered The industrial sectors to be covered shall be petrochemicals, oil refining, and chemical industries receiving, processing, storing, and/or exporting of volatile organic compounds (VOCs), and should include the emissions of VOCs from the natural gas processing/conditioning industry and the storage of natural gas and similar fuels, including methane. This will cover all the large industrial sources of VOCs emitted into the atmosphere within the EU, excluding transport. The scope of the standard and its contents should not restrict its use to the above mentioned industrial sectors, but allow it to be used as relevant by other industrial sectors. The standard shall address all VOC emissions to atmosphere, but exclude the emissions of VOCs into water and into solid materials such as soils. It is also anticipated that nearly all, or all, of the fugitive emission leaks from the process areas will be point sources, identified through the LDAR programme and investigated within the scope of the EN standard 15446:2008 - supplemented by OGI checks where practical. The types of emissions addressed by this standard shall be primarily those related to storage of VOCs, to VOC loading and unloading processes, and other industrial processes emitting diffuse and fugitive sources to atmosphere. Particularly this should include: (i) Storage media covering all types of tanks including:

• fixed-roof tanks, with and without internal floating roofs; • external floating–roof tanks; • VOC liquid sources exposed to atmosphere (normally low vapour pressure components); • hybrid tank covers; • High-pressure containment of liquid VOCs (including liquid-petroleum gas (LPG) liquefied-

natural gas (LNG) and others – e.g. propane); • Storage of natural gas and associated fuels as gaseous components.

(ii) Loading and unloading operations: • Loading of products used as inputs to industrial processes from other storage media (e.g.

other fixed tanks that are separated from the industrial process site for prior containment and/or stabilization);

• Rail, road, and ship vessel tanks for transportation; • Loading from fixed storage tanks in industrial processing areas into transport media (rail, road

and ship vessel tanks for transportation and/or distribution). (iii) Other diffuse sources:

• Waste-water treatment plant; • Basins and lagoons; • Coking units; • Flares; • Bitumen production and storage; • Process drains and other waste systems.

The standard shall not cover directly the determination of emissions from equipment and piping leaks that are already covered by the standard EN 15446:2008 I(except where relevant to the application of some of the monitoring techniques), but this standard shall be referred to and utilized in the development of the new standard when appropriate.
