The NOC-OTNOC-EOT issue

CEWEP-ESWET-FEADworkshop-ImplementationofBATConclusionsforWasteIncineration,Brussels,04.06.2019

•  IED requests compliance with ELVs in NOC on one hand and

within the R-EOT on the other one •  Definitions of NOC-OTNOC-EOT •  Missing information •  General proposals for implementation and compliance

Missing in the draft WI BREF BAT conclusions


•  The BAT conclusions do not include •  The mention that

•  BATAELsaresetinNOC•  BATAEL-basedELVsshouldbesetinNOC

•  The clear definitions of NOC and OTNOC (criteria to switch from one to the other during operation)

•  The calculation rules, e.g.: •  TherulestocalculateadailyaverageinNOCe.g.whensome½-hraveragevaluesofthedaywereinOTNOC

•  Themaximumnumberofnonvalidpointsinaday,etc.•  The fact that ½-hr BATAELs of 2006 WI BREF do not apply •  The fact that continuous sampling is usually performed in R-EOT

(and not in NOC)

•  NOC:NormalOperatingConditions•  OTNOC:OtherThanNormalOperatingConditions•  BATAELs:BATAssociatedEmissionLevels•  ELVs:EmissionLimitValues

8

The nature of BATAELs changed between IPPC and IED


•  Former BATAELs (under IPPC) were typical values. See yellow oval. •  New BATAELs are capping values. They should be based on maximum daily

average values of the year in NOC. See orange circles.

•  Former BATAELs should not be used under IED. •  Important because no new BATAELs for ½-hr averages in the revised WI BREF

Proposals 1


•  Definition of OTNOCs •  To use the list given in the IED and in the BREF drawing up Guidance

(Decision 2012/119/EU) •  To use the same rules as EIPPCB when filtering out the reported data •  To define end of start-up as when reaching stable state as for LCPs •  To use control system signals (alarms) to automatically identify OTNOCs

and NOC for both: •  CalculatingaveragevaluesinNOC•  OTNOCManagementPlan(seeBAT-c18)

•  Calculation of daily average values in NOC •  Use the same rules as EIPPCB when processing the reported data

10

Proposals 2


•  ELVs setting and checking •  No 1/2-hr BATAEL-based ELVs, as said the EIPPCB •  Using Article 15.3 (b) for assessment of capacity to meet BAT

performances, including non exceedance of daily and periodic BATAELs
