# Commission Implementing Decision (EU) 2015/2119 of 20 November 2015 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of wood-based panels (notified under document C(2015) 8062) (Text with EEA relevance), Division BAT 14: BAT is to monitor emissions to air and water and to monitor process flue-gases in accordance with EN standards with at least the frequency given below. If EN standards are not available, BAT is to use ISO, national or other international standards that ensure the provision of data of an equivalent scientific quality.

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

Monitoring of emissions to air from the dryer and for combined treated emissions from the dryer and the press
Methane monitored according to EN ISO 25140 or EN ISO 25139 is subtracted from the result when using natural gas, LPG, etc. as a fuel.
Not relevant when using mainly wood-derived fuels, natural gas, LPG, etc. as a fuel.
Including As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, Sb, Tl and V.
Relevant if contaminated recovered wood is used as fuel.
Relevant if SNCR is applied.
In the absence of an EN standard, the preferred approach is isokinetic sampling in an impinging solution with a heated probe and filter box and without probe washing, e.g. based on the US EPA M316 method.
