Division DEFINITIONS
United Kingdom
For the purposes of these BAT conclusions, the following definitions apply:
| General terms | |
|---|---|
| Term used | Definition |
| Base coat | Paint which, when applied to a substrate, determines the colour and the effect (e.g. metallic, pearlescent). |
| Batch discharge | Discharge of a discrete, contained volume of water. |
| Clear coat | Coating material which, when applied to a substrate, forms a solid transparent film with protective, decorative or specific technical properties. |
| Combiline | Combination of hot-dip galvanising and coil coating in the same process line. |
| Continuous measurement | Measurement using an automated measuring system permanently installed on site for continuous monitoring of emissions, according to EN 14181. |
| Direct discharge | Discharge to a receiving water body without further downstream waste water treatment. |
| Emission factors | Coefficients that can be multiplied by known data such as plant/process data or throughput data to estimate emissions. |
| Existing plant | A plant that is not a new plant. |
| Fugitive emissions | Fugitive emissions as defined in Article 57(3) of Directive 2010/75/EU. |
| Grade B or C creosote | Types of creosote for which specifications are given in EN 13991. |
| Indirect discharge | Discharge which is not a direct discharge. |
| Major plant upgrade | A major change in the design or technology of a plant with major adjustments or replacements of the process and/or abatement technique(s) and associated equipment. |
| New plant | A plant first permitted on the site of the installation following the publication of these BAT conclusions or a complete replacement of a plant following the publication of these BAT conclusions. |
| Off-gas | The gas extracted from a process, piece of equipment or area which is either directed to treatment or discharged directly to air through a stack. |
| Organic compound | Organic compound as defined in Article 3(44) of Directive 2010/75/EU. |
| Organic solvent | Organic solvent as defined in Article 3(46) of Directive 2010/75/EU. |
| Plant | All parts of an installation that carry out an activity listed in point 6.7 or 6.10 of Annex I to Directive 2010/75/EU and any other directly associated activities which have an effect on consumption and/or emissions. Plants may be new plants or existing plants. |
| Primer coat | Paint formulated for use as a layer on a prepared surface, to provide good adhesion, protection of any layers below and filling of surface irregularities. |
| Sector | Any of the surface treatment activities that are part of activities listed in point 6.7 of Annex I to Directive 2010/75/EU and are referred to in Section 1 of these BAT conclusions. |
| Sensitive receptor | Area which needs special protection, such as:
|
| Solid mass input | The total mass of solids used as defined in Part 5, 3(a)(i) of Annex VII to Directive 2010/75/EU. |
| Solvent | ‘Solvent’ refers to ‘organic solvent’. |
| Solvent input | The total quantity of organic solvents used as defined in Part 7, 3(b) of Annex VII to Directive 2010/75/EU. |
| Solvent-based (SB) | Type of paint, ink or other coating material using solvent(s) as the carrier. For the preservation of wood and wood products, it refers to the type of treatment chemicals. |
| Solvent-based-mix (SB-mix) | Solvent-based coating where one of the coating layers is water-based (WB). |
| Solvent mass balance (SMB) | A mass balance exercise conducted at least once every year according to Part 7 of Annex VII to Directive 2010/75/EU. |
| Surface run-off water | Water from precipitation that flows over land or impervious surfaces, such as paved streets and storage areas, rooftops, etc. and does not soak into the ground. |
| Total emissions | The sum of fugitive emissions and emissions in waste gases as defined in Article 57(4) of Directive 2010/75/EU. |
| Treatment chemicals | Chemicals used in wood and wood products preservation such as biocides, chemicals used for waterproofing (e.g. oils, emulsions) and flame retardants. This also includes the carrier of active substances (e.g. water, solvent). |
| Valid hourly/half-hourly average | An hourly/half-hourly average is considered valid when there is no maintenance or malfunction of the automated measuring system. |
| Waste gases | Waste gases as defined in Article 57(2) of Directive 2010/75/EU. |
| Water-based (WB) | Type of paint, ink or other coating material in which water replaces all or part of the solvent content. For the preservation of wood and wood products, it refers to the type of treatment chemicals. |
| Wood preservation | Activities whose purpose is to protect wood and wood products from the damaging effects of fungi, bacteria, insects, water, weather or fire; to provide long-term conservation of structural integrity; and to improve the resistance of wood and wood products. |
| Pollutants and parameters | |
