(iii) fibrous vegetable waste from virgin pulp production and from production of paper from pulp, if it is co-incinerated at the place of production and the heat generated is recovered;

(iv) cork waste;

(v) wood waste with the exception of wood waste which may contain halogenated organic compounds or heavy metals as a result of treatment with wood preservatives or coating and which includes, in particular, such wood waste originating from construction and demolition waste;

"combustion plant" means any technical apparatus in which fuels are oxidised in order to use the heat thus generated;

"diesel engine" means an internal combustion engine which operates according to the Diesel cycle and uses compression ignition to burn fuel;

"dual fuel engine" means an internal combustion engine which uses compression ignition and operates according to the Diesel cycle when burning liquid fuels and according to the Otto cycle when burning gaseous fuels;

"dust" means particles, of any shape, structure or density, dispersed in the gas phase at the sampling point conditions which may be collected by filtration under specified conditions after representative sampling of the gas to be analysed, and which remain upstream of the filter and on the filter after drying under specified conditions;

"emission" means the discharge of substances from a combustion plant into the air;

"emission limit value" means the permissible quantity of a substance contained in the waste gases from a combustion plant which may be discharged into the air during a given period and shall be expressed at standard conditions according to the following equation:

Where:

[P] is the mass concentration of the pollutant at s standard conditions.

[P] is the mass concentration of the pollutant M measured at the temperature T in Kelvin (K), at the Pressure P in kilopascal (kPa), at the percentage flue gas water vapour content W and at the flue gas oxygen content of O . M T is the actual flue gas temperature in K.

P is the actual flue gas pressure in kPa.

W is the percentage water vapour content of the flue gas. O is the standard oxygen content by volume s in the flue gas, which shall be 6% for medium combustion plants using solid fuels, 3% for medium combustion plants, other than engines and gas turbines, using liquid and gaseous fuels and 15% for engines and gas turbines.

O is the measured oxygen content in the flue M gas.

"engine" means a gas engine, diesel engine or dual fuel engine;

"existing combustion plant" means a combustion plant put into operation before 20 December 2018 or for which a permit was granted before 19 December 2017 pursuant to the

Ambient Air Quality Regulations provided that the plant is put into operation no later than 20 December 2018;

"fuel" means any solid, liquid or gaseous combustible material;

"gas engine" means an internal combustion engine which operates according to the Otto cycle and uses spark ignition to burn fuel;

"gas oil" means:

a) any petroleum-derived liquid fuel falling within CN codes 2710 19 25, 2710 19 29, 2710 19 47, 2710 19 48, 2710 20 17 or 2710 20 19; or b) any petroleum-derived liquid fuel of which less than 65% by volume (including losses) distils at 250°C and of which at least 85% by volume (including losses) distils at 350°C by the ASTM D86 method;

"gas turbine" means any rotating machine which 549.122 COMBUSTION PLANTS

converts thermal energy into mechanical work, consisting mainly of a compressor, a thermal device in which fuel is oxidised in order to heat the working fluid, and a turbine; this includes both open cycle and combined cycle gas turbines, and gas turbines in cogeneration mode, all with or without supplementary firing;

"heavy fuel oil" means:

a) any petroleum-derived liquid fuel falling within CN codes 2710 19 51 to 2710 19 68, 2710 20 31, 2710 20 35, or 2710 20 39; or b) any petroleum-derived liquid fuel, other than gas oil, which, by reason of its distillation limits, falls within the category of heavy oils intended for use as fuel and of which less than 65% by volume (including losses) distils at 250 °C by the ASTM D86 method. If the distillation cannot be determined by the ASTM D86 method, the petroleum product is likewise categorised as a heavy fuel oil;

"micro isolated system" or "MIS" means any system with consumption less than 500 GWh in the year 1996, where there is no connection with other systems;

"natural gas" means naturally occurring methane with no more than 20% (by volume) of inerts and other constituents;
