Determination of start-up and shut-down periods for combustion plants consisting of two or more units
Article 5
1
For the purpose of calculating the average emission values as set out in point 1 of Part 4 of Annex V to Directive 2010/75/EU, the following rules shall apply for determining the start-up and shut-down periods of combustion plants consisting of two or more units:
a
the values measured during the start-up period of the first unit starting up and during the shut-down period of the last combustion unit shutting down shall be disregarded;
b
the values determined during other start-up and shut-down periods of individual units shall be disregarded only if they are measured or, where no measurement is technically or economically feasible, calculated separately for each of the units concerned.
2
For the purpose of point (27) of Article 3 of Directive 2010/75/EU, the start-up and shut-down periods of combustion plants consisting of two or more units shall only consist of the start-up period of the first combustion unit starting up and the shut-down period of the last combustion unit shutting down.
For combustion plants for which points 2, 4 and 6 of Part 1 of Annex V to Directive 2010/75/EU allow the application of an emission limit value to part of the plant discharging its waste gases through one or more separate flues within a common stack, the start-up and shut-down periods may be determined for each of those parts of the combustion plant separately. The start-up and shut-down periods for a part of the plant shall then consist of the start-up period of the first combustion unit starting up within that part of the plant and the shut-down period of the last combustion unit shutting down within that part of the plant.
