BATBest Available Techniques (IED Article 3(10): the “most effective and advanced stage in the development of activities and their methods of operation which indicates the practical suitability of particular techniques for providing the basis for emission limit values and other permit conditions designed to prevent and, where that is not practicable, to reduce emissions and the impact on the environment as a whole.The notion of the three BAT elements are further clarified as follows:“best” = most effective in achieving high level of environmental protection as a whole“available” = developed at a scale which allows implementation in relevant industrial sector under economically and technically viable conditionsbased on cost/benefit considerations.“techniques” = technology used but also the way in which the installation is designed, built, maintained, operated and decommissioned.
BATCBAT conclusions (IED Article 3(12) : a document containing the parts of a BAT reference document laying down the conclusions on best available techniques, their description, information to assess their applicability, the emission levels associated with the best available techniques, associated monitoring, associated consumption levels and, where appropriate, relevant site remediation measures). These have clearly binding status under the IED.

BREFBAT reference document. Currently there are 33 BREFs, all are listed on The European Commission’s BREF webpage.
BREF review rulesCommission Implementing Decision 2012/119/EU of 10 February 2012 laying down rules concerning guidance on the collection of data and on the drawing up of BAT reference documents and on their quality assurance referred to in Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions.
BAT-AELBAT-Associated Emission Level (IED Art 3(13)) : the range of emission levels obtained under normal operating conditions using a best available technique or a combination of best available techniques, as described in BAT conclusions, expressed as an average over a given period of time, under specified reference conditions.

ELVEmission Limit Value. (See IED Art. 3(5): the mass, expressed in terms of certain specific parameters, concentration and/or level of an emission, which may not be exceeded during one or more periods of time). ELVs are set in permits issued to plants covered by the IED.
EoLVEnd-of-Life Vehicles
ENEEnergy Efficiency
EMSEnvironmental management systems
EQSEnvironmental Quality Standard. These are further defined in the IED under Article 3(6) and Article 18, where a clear link with BAT is established. Typically these refer to air quality and water quality standards set under EU environmental protection legislation. Additional measures should be set in operating permits -even if these go beyond BAT- in order to ensure compliance with EQS. EQS are therefore a strong driving force for industry to improve environmental performance.

NOCNormal Operating Conditions. (See OTNOC for distinction with what is considered as not “normal”). In waste incineration Effective Operation Time (EOT) is also used for regulatory compliance purposes
OPEXOperating expenditure/costs
OTNOCOther Than Normal Operating Conditions. This term is not clearly defined, but would include those situations judged as “not normal”. This includes the following situations: malfunctions, leaks, momentary stoppages. It is relevant for the compliance with the BAT-AEL, derived on environmental performance under “normal operating conditions”. This is a particularly relevant issue during start up and shut down conditions, where emissions are generally higher e.g. Large Combustion Plants.

PHSPriority Hazardous Substance as specified in Annex X of the Water Framework Directive 2000/60/EC and its daugther Directive 2013/39/EU as regards priority substances in the field of water policy (EQS Directive) . Maximum Allowable Concentration values (MAC) for these substances (21) or biota limits are set, which need to be met in EU surface waters. There is a phase out obligation on PHS, which means a 0 immission in water bodies of those substances to achieve “good chemical and ecological status” of EU surface waters
