ANNEX

1. Combustion plants to be included in the transitional national plan

Parts of combustion plants (e.g. one or more individual combustion units which are sharing a common stack with other units or which are in a situation as set out in Article 29(2) of Directive 2010/75/EU) shall not fall under a transitional national plan (1).

For the purpose of the second indent, point (b) of Article 32(1) of Directive 2010/75/EU, combustion plants falling under that provision also include plants which are not operated by a refinery operator, but are located within the refinery and use the fuels referred to in that point.

Combustion plants that will be subject to the provisions of Chapter IV of Directive 2010/75/EU concerning waste incineration plants and waste co-incineration plants at any point during the application of the transitional national plan shall not be included in the transitional national plan.

2. Combustion plant data to be included in the transitional national plan

The transitional national plan shall include a list of all the combustion plants it covers and all data concerning these plants which was used to calculate the emission ceilings.

The plant-by-plant data to be included relates to the total rated thermal input, the fuels used and the operating characteristics of each combustion plant during the time period of the implementation of the transitional national plan.

As a minimum, the following data shall be included in the transitional national plan for each of the combustion plants falling under it:

(1) Name and location of the combustion plant (2);

(2) Date on which the first permit for the combustion plant was granted;

(3) Date on which the application for the first permit for the combustion plant was submitted alongside with the date on which the combustion plant was put into operation for the first time; Note: This information is only required in case the combustion plant has been granted its first permit after 27 November 2002, but has been brought into operation no later than 27 November 2003.

(4) Any extension by at least 50 MW of the total rated thermal input of the combustion plant, which took place between 27 November 2002 and 31 December 2010 (indicating the capacity added in MW) (3);

(5) Total rated thermal input (MW) of each combustion plant on 31 December 2010;

(6) Annual number of operating hours (4) of each combustion plant, averaged over the period 2001-2010; Note: This information is only required in case where specific emission limit values for combustion plants operating less than 1 500 hours per year are used to calculate the contribution of the combustion plant to the emission ceiling(s).

(7) Pollutants for which the combustion plant concerned is not covered by the transitional national plan (if any) (5).

(8) Annual amount of fuel used (TJ/year), averaged over the period 2001-2010, split over 6 fuel types: hard coal, lignite, biomass, other solid fuels, liquid fuels, gaseous fuels (6);

(9) Annual waste gas flow rate (Nm3/year), averaged over the period 2001-2010 (7); Note 1: In the case of combustion plants firing multiple fuel types and/or consisting of multiple plant types, the waste gas flow rate needs to be provided for each of the fuel types and/or combustion plant types separately (8). Note 2: If the waste gas flow rate is calculated from the amount of fuel used (and not based on actual monitored waste gas flows), the factor (or factors in case of multiple fuels or combustion plant types) used for the calculation (Nm3/GJ) needs to be reported.

(10) Quantity of sulphur input via indigenous solid fuels (9) used (tonnes S/year), averaged over the period 2001-2010; Note: This information is only required in case where the combustion plant uses indigenous solid fuels and where the minimum desulphurisation rate is used to calculate the contribution of the combustion plant to the emission ceiling for sulphur dioxide (for 2016 and/or 2019).

Where combustion plants covered by the transitional national plan are gas turbines or gas engines, the transitional national plan must specifically indicate this.

3. Determining the emission ceilings

3.1. Calculation method for the individual plant contributions to the 2016 and 2019 emission ceilings

3.1.1. General case

In order to determine the applicable emission ceilings for a pollutant for the years 2016 and 2019, the contribution of each combustion plant expressed in tonnes per year (tpa) shall be calculated using the following equation:

Contribution to ceiling (tpa) = Waste gas flow rate (Nm3pa) × ELV (mg/Nm3) × 1,0 × 10–9

where:

— ‘Waste gas flow rate’ is the volumetric flow rate of waste gases expressed in cubic metres per year (Nm3pa), averaged over the years 2001-2010. It is expressed at standard temperature (273 K) and pressure (101,3 kPa), at the relevant reference oxygen content (i.e. the same one as used for the emission limit value (ELV)) and after correction for the water vapour content,

— ‘ELV’ is the relevant emission limit value for the pollutant concerned expressed in mg/Nm3, assuming an oxygen content by volume in the waste gas of 6 % in the case of solid fuels, 3 % in the case of liquid and gaseous fuels (for combustion plants other than gas turbines or gas engines) and 15 % in the case of gas turbines and gas engines.

The details on how to determine the emission limit values for calculating the 2016 and 2019 emission ceilings are provided in sections 3.2 and 3.3.

3.1.2. Specific case of plants firing multiple fuel types and/or consisting of multiple plant types

The equation referred to in section 3.1.1 cannot be used for combustion plants that fired multiple fuel types in the period 2001-2010 (simultaneously or not) or are consisting of multiple plant types.

Those combustion plants require the application of different emission limit values and/or reference conditions for calculating their contribution to the emission ceilings. Hence, the following method shall be used.

Contribution to ceiling (tpa) = Σ [Waste gas flow rate (Nm3pa) × ELV (mg/Nm3) × 1,0 × 10–9]

This equation implies that, for each of the fuel types used in the period 2001-2010, the average annual waste gas volume (Nm3 per year) is multiplied by the relevant emission limit value (corresponding to the total rated thermal input of the entire combustion plant). The products of these multiplications are then added for all of the fuel types used.

It must be ensured that, for each fuel type, the waste gas volume and the emission limit value multiplied are expressed at the same reference oxygen content.

The same approach applies in cases where, in the period 2001-2010, taking into account Article 29(1) and (2) of Directive 2010/75/EU, a single combustion plant consisted of a combination of different plant types. Illustrative examples are:

— one or more gas turbines combined with one or more other types of combustion plants,

— one or more gas engines combined with one or more other types of combustion plants.

3.1.3. Minimum rate of desulphurisation (MDR)

The equation referred to in section 3.1.1 cannot be used for combustion plants firing indigenous solid fuel (10) and which cannot comply with the relevant emission limit values set for sulphur dioxide in Directive 2010/75/EU due to the characteristics of this fuel.

For such plants, the calculation of their contribution to the emission ceiling applicable for sulphur dioxide may be based on the application of the relevant minimum rates of desulphurisation (11) rather than on the emission limit values for sulphur dioxide.

In that case, the contribution of the combustion plant to the sulphur dioxide emission ceiling expressed in tonnes per year (tpa) shall be calculated using the following equation:

Contribution to SO2 ceiling (tpa) = Sulphur input (tpa) × (1 – (MDR/100)) × 2

where:

— ‘Sulphur input’ is the annual quantity of sulphur (S) contained in the indigenous solid fuel which was used in the combustion plant, expressed in tonnes per year (tpa), averaged over the period 2001-2010,

— ‘MDR’ is the relevant minimum rate of desulphurisation, expressed in percent.

The details on how to determine the relevant minimum rate of desulphurisation for calculating the 2016 and 2019 emission ceilings for sulphur dioxide are provided in sections 3.2 and 3.3.

3.2. Relevant emission limit values and minimum rates of desulphurisation for calculating the 2016 emission ceilings

According to Article 32(3) of Directive 2010/75/EU, the emission ceiling(s) for the year 2016 shall be calculated on the basis of the relevant emission limit values set out in Annexes III to VII to Directive 2001/80/EC or, where applicable, on the basis of the minimum rate of desulphurisation set out in Annex III to Directive 2001/80/EC. Thus, the calculation of the 2016 emission ceilings is based upon the relevant emission limit values and MDR, which would have been applicable on 1 January 2016 to the combustion plant concerned under Directive 2001/80/EC, taking into account the following provisions (12).

The emission limit values and MDR shall be determined on the basis of the total rated thermal input of the entire combustion plant on 31 December 2010, the type(s) of fuel used and the annual number of operating hours averaged over the period 2001-2010. Where combustion plants have been extended by at least 50 MW in the period between 27 November 2002 and 31 December 2010, the rules for calculating the relevant emission limit values as set out in Article 10 of Directive 2001/80/EC shall be applied.

For all gas turbines included in the transitional national plan, the relevant emission limit value concerning nitrogen oxides is the one set out in Part B of Annex VI to Directive 2001/80/EC, irrespective of Article 2(7)(j) of Directive 2001/80/EC.

As no emission limit values have been set out in Directive 2001/80/EC for gas engines, the relevant emission limit value for nitrogen oxides is the one set out in Part 1 of Annex V to Directive 2010/75/EU.

For combustion plants which have been using different fuel types in the period 2001-2010, the relevant emission limit values shall be listed for each individual fuel. Section 3.1.2 provides details on the method to be used to calculate the contribution of each of those plants to the emission ceilings.

Directive 2001/80/EC allows certain combustion plants operating less than 1 500 hours (as a rolling average over a five-year period) to comply with less stringent emission limit values. The, latter can only be used for calculating the contribution of an individual plant to the 2016 emission ceiling if the average number of operating hours for the plant over the years 2001-2010 is less than 1 500 hours per year.

An overview of the relevant emission limit values as set out in Annexes III to VII of Directive 2001/80/EC and of the relevant MDR established in Annex III to Directive 2001/80/EC is provided in Tables C.1, C.2 and C.3 in Appendix C to this Annex (13).

3.3. Relevant emission limit values and minimum rates of desulphurisation for calculating the 2019 emission ceilings

According to Article 32(3) of Directive 2010/75/EU, the emission ceilings for the year 2019 shall be calculated on the basis of the relevant emission limit values set out in Part 1 of Annex V to Directive 2010/75/EU or, where applicable, the relevant rates of desulphurisation set out in Part 5 of Annex V to Directive 2010/75/EU. Thus, the calculation of the 2019 emission ceilings is based upon the relevant emission limit values and MDR, which would be applicable on 1 January 2019 under Directive 2010/75/EU to the combustion plant concerned.

The emission limit values and MDR shall be determined on the basis of the total rated thermal input of the entire combustion plant on 31 December 2010, of the type(s) of fuel used and of the annual number of operating hours averaged over the period 2001-2010.

An overview of the relevant emission limit values as set out in Part 1 of Annex V to Directive 2010/75/EU and of the relevant MDR established in Part 5 of Annex V to Directive 2010/75/EU is provided in Tables D.1, D.2 and D.3 in Appendix D of this Annex.

For combustion plants which have been using different fuel types in the period 2001-2010, the relevant emission limit values shall be listed for each individual fuel. Section 3.1.2 provides details on the method to be used to calculate the contribution of each of those plants to the emission ceilings.

Directive 2010/75/EU allows certain combustion plants operating less than 1 500 hours (as a rolling average over a five-year period) to comply with less stringent emission limit values. The latter can only be applied for calculating the contribution of a plant to the 2019 emission ceiling if the average number of operating hours for that plant over the years 2001-2010 is less than 1 500 hours per year.

3.4. Calculating the emission ceilings

3.4.1. Calculating the 2016 and 2019 emission ceilings

For the years 2016 and 2019, the total emission ceilings per pollutant shall be determined by adding up the contributions of each individual plant to the respective emission ceilings:

ceiling2016 (tpa) = Σ [individual plant contribution to 2016 ceiling]

ceiling2019 (tpa) = Σ [individual plant contribution to 2019 ceiling]

3.4.2. Calculating the 2017, 2018 and 2020 emission ceilings

The ceilings for the year 2017 (ceiling2017) shall be calculated using the following equation:

The ceilings for the year 2018 (ceiling2018) shall be calculated using the following equation:

The ceilings for the first semester of 2020 (ceiling2020) are half of the ceilings for 2019:

4. Subsequent changes to transitional national plans

Member States shall inform the Commission at least on the following:

(a) the combustion plants which opt for the limited lifetime derogation in accordance with Article 33 of Directive 2010/75/EU; Note: While Member States shall communicate their transitional national plans to the Commission on 1 January 2013 at the latest, operators have until 1 January 2014 to notify the competent authority whether they seek to opt for the limited lifetime derogation. Thus, a combustion plant may be initially included in the transitional national plan submitted to the Commission before being subject to a limited lifetime derogation. The combustion plant must then be removed from the transitional national plan once the competent authority has been notified by the operator of the combustion plant about the decision to opt for the limited lifetime derogation. The contributions to the applicable emission ceiling(s) of each of the combustion plants that would fall under Article 33 of Directive 2010/75/EU must then be deducted from the emission ceiling(s) as calculated in the latest accepted version of the transitional national plan (or, if no such plan has been accepted, as calculated in the latest version of the transitional national plan submitted to the Commission).

(b) the combustion plants which are closed (i.e. those plants that have definitively stopped operating) or the total rated thermal input of which is reduced to less than 50 MW;

(c) the combustion plants which start to co-incinerate waste after 31 December 2015 and which would therefore fall under Chapter IV of Directive 2010/75/EU. Note: As mentioned in Article 32(3) of Directive 2010/75/EU, where a plant included in the transitional national plan is closed or no longer falls within the scope of Chapter III of Directive 2010/75/EU, this shall not result in an increase in total annual emissions from the remaining plants covered by the transitional national plan.

For the purpose of Article 32(6) of Directive 2010/75/EU, Member States do not have the obligation to communicate to the Commission the following information since the subsequent changes they refer to should not affect the applicable emission ceiling(s):

— a reduction or an increase of the total rated thermal input after 31 December 2010 (other than a reduction to less than 50 MW),

— a reduction or an increase of the number of annual operating hours after 2010,

— a change in fuel use (type, quantity) occurring after 2010 (other than a switch to burning waste, which would qualify the plant as a waste co-incineration plant causing its exclusion from the transitional national plan).

Changes affecting the name of the plant (e.g. due to a change of operator) shall be reported via the emission inventories to be provided by Member States in accordance with Article 6(3) of this Decision and Article 72(3) of Directive 2010/75/EU.

(1) The same rule applies regarding Articles 33, 34 and 35 of Directive 2010/75/EU. Consequently, a part of a combustion plant cannot be covered by the provisions of Article 33, 34 or 35, while another part (or parts) of that plant would be included in the transitional national plan.

(2) As has been reported in the emission inventories drawn up under Directive 2001/80/EC of the European Parliament and of the Council of 23 October 2001 on the limitation of emissions of certain pollutants into the air from large combustion plants (OJ L 309, 27.11.2001, p. 1).

(3) This information is needed in view of determining the relevant emission limit values on 1 January 2016 as set out in Article 10 of Directive 2001/80/EC.

(4) ‘operating hours’ means the time, expressed in hours, during which a combustion plant, in whole or in part, is operating and discharging emissions into the air, excluding start-up and shut-down periods.

(5) For example, gas turbines can only be covered by the transitional national plan concerning their NOx emissions. Other plants may be covered by the transitional national plan for some pollutant(s), while being subject to the emission limit values from Annex V to Directive 2010/75/EU for other pollutants.

(6) For combustion plants which, at any point during the period 2001-2010, have been co-incinerating waste (other than waste which is ‘biomass’ according to the definition under Article 3(31)(b) of Directive 2010/75/EU and were consequently covered by Directive 2000/76/EC of the European Parliament and of the Council of 4 December 2000 on the incineration of waste (OJ L 332, 28.12.2000, p. 91)), the amount of waste burned during that period shall not be included under this point.

(7) See section 3.1.1 of this Annex concerning the applicable reference conditions.

(8) See section 3.1.2 of this Annex.

(9) ‘indigenous solid fuel’ means a naturally occurring solid fuel fired in a combustion plant specifically designed for that fuel and extracted locally.

(10) This applies for combustion plants which have been firing indigenous solid fuel in the period 2001-2010.

(11) ‘rate of desulphurisation’ means the ratio over a given period of time of the quantity of sulphur which is not emitted into air by a combustion plant to the quantity of sulphur contained in the solid fuel which is introduced into the combustion plant facilities and which is used in the plant over the same period of time.

(12) The relevant emission limit values for calculating the emission ceilings are not affected by the inclusion of a plant in a National Emission Reduction Plan under Article 4(6) of Directive 2001/80/EC.

(13) This overview is not exhaustive. In particular, it does not cover situations where a combustion plant had been extended by at least 50 MW between 27 November 2002 and 31 December 2010, in which case also the emission limit values listed in the Parts B of Annexes III to VII to Directive 2001/80/EC are of relevance (application of Article 10 of Directive 2001/80/EC).
