# Commission Implementing Decision (EU) 2020/2009 of 22 June 2020 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for surface treatment using organic solvents including preservation of wood and wood products with chemicals (notified under document C(2020) 4050) (Text with EEA relevance), Division BAT 52: In order to reduce NOX emissions in waste gases while limiting CO emissions from the thermal treatment of off-gases in wood and wood products preservation using creosote and/or solvent-based treatment chemicals, BAT is to use technique (a) or both of the techniques given below.

Extent: E+W+S+N.I.

Technique
Description
Applicability
(a)
Optimisation of thermal treatment conditions
(design and operation)
See BAT 17 (a).
Design applicability may be restricted for existing plants.
(b)
Use of low-NOX burners
See BAT 17 (b).
Applicability may be restricted at existing plants by design and/or operational constraints.
Table 37
BAT-associated emission level (BAT-AEL) for NOX emissions in waste gases and indicative emission level for CO emissions in waste gases to air from the thermal treatment of off-gases in wood and wood products preservation using creosote and/or solvent-based treatment chemicals
The BAT-AEL and indicative level do not apply where off-gases are sent to a combustion plant.
Parameter
