3. 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma3 Definition of BAT Best Most effective in achieving a high general level of protection of the environment as a whole; AvailableDeveloped on a scale which allows implementation in the relevant industrial sector, under economically and technically viable conditions; TechniquesBoth the technology used and the way in which the installation is designed, built, maintained, operated and decommissioned. Determining BAT, special consideration should be given to the criteria listed in Annex III of IED

4. Criteria for determining best available techniques: 1. the use of low-waste technology; 2. the use of less hazardous substances; 3. the furthering of recovery and recycling of substances generated and used in the process and of waste, where appropriate; 4. comparable processes, facilities or methods of operation which have been tried with success on an industrial scale; 5. technological advances and changes in scientific knowledge and understanding; 6. the nature, effects and volume of the emissions concerned; IED Annex III 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma4

5. 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma5 ‘BAT reference documents’ (BREFs)  Provide ‘BAT conclusions’ which shall be the reference for setting permit conditions  Structured and prepared on the basis of established guidelines  Based on an intensive exchange of information on: the performance of installations and techniques in terms of emissions and consumptions, etc. the techniques used, associated monitoring, economic and technical viability, etc. best available techniques and emerging techniques identified after considering all the issues concerned

6. 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma6 Preparation of the BREF documents

7. 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma7  Current LCP BAT reference document was published in July 2006 and drafted between 1999 and 2004.  600-page document on combustion and environmental protection techniques, and in particular achievable emission levels by using BAT (BAT-AELs / BAT ranges)  Covers combustion plant with rated thermal input over 50 MW  BAT-AELs mainly on conventional fuel basis (coal and lignite, biomass and peat, liquid fuels and gaseous fuels)  BAT-AELs are given separately for new and existing plants  Includes co-combustion of solid waste and secondary fuels  Current LCP BREF does not consider different load modes (emergency, peak load, mid-merit, base load) LCP BREF

8. Fuel storage and pretreatment and CO emissions  BAT process descriptions are given for unloading, storage and handling of fuel and additives  BAT for fuel pretreatment is to consider blending and mixing in order to ensure stable combustion conditions and to reduce peak emissions  BAT for biomass and peat combustion is to consider drying to reduce the amount of water in peat and biomass, drying of fuel is also considered to be part of BAT  For liquid fuels BAT is to consider various pretreatment devices depending on fuel and proces  BAT to reduce CO emissions it to ensure complete combustion, along with furnace design, monitoring and process control and maintanence, BAT-AELs are given for gas combustion 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma8

9. Thermal efficiency

10. Thermal efficiency (2)  No Specific BAT values for liquid fuels in boilers and engines 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma10

11. Particles  Emissions from natural gas combustion are normally below 5 mg/m 3 without any abatement  BAT to reduce heavy metals is to use ESP or fabric filter 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma11

12. SO 2 emissions

13. NO X emissions (coal and lignite)

14. NO x emissions (biomass and peat) 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma14

15. NO x emissions (biomass, peat and gas)

16. NO x emissions (gas continuing) 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma16

17. Waste water, waste and co-combustion  BAT is to collect and treat all surface run-off waters before discharge  BAT is to apply oil separation wells to prevent emissions  BAT is to treat flue gas cleaning waste waters by adjusting the pH level, precipitate heavy metals and remove the solid matter  For by-products utilization and re-use is the best available option depending on waste quality  Generally the same BAT apply for co-combustion of secondary fuels (waste) as for conventional LCPs. The need for adjusting the flue gas cleaning, limitations on secondary fuel input and changes in combustion residue quality need to be addressed in case by case 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma17

18.  All permits for Finnish LCP’s were reconsidered 2005-2008 because of the LCP- and IPPC-Directives  Majority of the large combustion plants have currently emission limit values based on LCP Directive  LCPD based ELV’s for new (>2003) plants are often sufficient to ensure operation within BAT-AEL’s  Some more recent permits for existing (<2003) plants have lower ELV’s than LCPD, based in current BAT-AEL’s in the LCP BREF (2006)  BAT-based permitting for 5-50 MW plants from 2005 to 2010 and currently legislated minimum ELVs 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma18 Current situation in LCP’s and BAT

19.  LCP BAT group is an expert group under environmental administration preparing the Finnish input to LCP BREF review process  Members from industry, technology suppliers, environmental authorities (ministry, permit writers and surveillance) and environmental NGO  Two TWG members from environmental authority and VTT  Re-established two years before the start of the LCP BREF review  Work based on voluntary contributions, which are partly supported by projects 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma19 Finnish LCP BAT group

20.  Peak and reserve combustion plants  Co-incineration and multi-firing combustion plants  Biomass and Peat  District heat production  Combined heat and power production  Fluidised bed combustion  Gasification  Engines 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma20 Key areas for input to the BREF review

22.  Usually monitoring of the permit conditions is made by the operator (self-monitoring) and partly by a third-party monitoring organisation  the operator presents a monitoring plan in the permit application  The monitoring plan is reviewed by authority and accepted as a part of the permit or in a separate acceptance process  Legislation enables joint monitoring by several operators  Monitoring data cannot be declared secret  The authority does a periodical checking of the monitoring results, regional authority does very little monitoring (water emissions, noise) Monitoring and control 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma22

23.  Legislation sets some overall requirements for monitoring and control  Measurements, tests and investigations shall be done in a qualified, reliable and appropriate way  Data from EMAS and ISO 14001 could be utilised  Third-party monitoring/analyses are utilised in almost all industrial sites  On the site inspections the inspector makes and documents the observations on the reliability and accuracy of monitoring Monitoring and control (2) 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma23

24.  Self-monitoring is typically the ‘every-day’ monitoring of the industry  Typically self-monitoring is reported on annual basis, for LCPs air emission data is reported in some case monthly  The scope of self-monitoring can vary between operations and locations  Some large industry have accredited laboratories for environmental monitoring. Even in these cases there has been requirement for third-party monitoring Self-monitoring by an operator 1.10.2012Regional State Administrative Agency for Southern Finland, Jaakko Kuisma24
