2. Background Article 9(5) of the IPPC Directive Horizontal document
Link with the work of other organisations (IMPEL, CEN, EPER,…)
TWG of about 45 members
Finished in 2002

4. Main difficulties overcome
Definition of the scope
Definition of the structure
Harmonisation
Contributions

5. Objectives of the document
Provide information to guide IPPC permit writers and operators when setting/proposing monitoring conditions associated to ELVs
Improve comparability and reliability of monitoring data

6. Different types of monitoring
Emission monitoring
Process monitoring
Impact monitoring

7. Monitoring issues to consider in issuing IPPC permits
“Why” monitor?
“Who” carries out the monitoring?
“What” and “how” to monitor
“How” to express ELVs and monitoring results
Monitoring timing considerations
How to deal with uncertainties
Monitoring requirements to be included with ELVs in permits

8. Accounting for total emissions
Emissions from point sources
Fugitive and diffuse emissions
Exceptional emissions
Values under the limit of detection
Outliers

9. Data production chain Comparability and reliability of data
The steps of the data production chain
1. Flow/amount measurement
2. Sampling
3. Sample storage, transport and preservation
4. Sample treatment
5. Sample analysis
6. Data processing
7. Reporting
Data production chain for the different media

10. Different approaches to monitoring
Direct measurements
Surrogate parameters
Mass balances
Calculations
Emission factors

11. Compliance assessment
3 items:
the measurement
uncertainty
ELV
3 categories:
compliant
borderline
non-compliant

12. Reporting of monitoring
Requirements
Audiences
Responsibilities
Scope of the report
Type of report
Good reporting practices
Quality considerations

13. Costs of emission monitoring
Cost-effectiveness
Shared monitoring costs
Elements of costs

14. Conclusions Scope and structure were difficult to set
General document with no specific details
Increase awareness on important monitoring issues
No BAT, some Good Practices

15. Thank you for your attention!
