Article 5Determination of start-up and shut-down periods for combustion plants consisting of two or more units
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.
