4. For combustion plants firing coal or lignite, measured emissions of total mercury at least once a year.


5. As an alternative to the in point 3 measurements of SO2 and NOx may be used other approaches, such as authentication or supervisory authority has verified and approved, to determine the emissions of SO2 and NOx. In these procedures shall use relevant CEN standards or, if CEN standards are not available, ISO standards or national or other international standards which will ensure the provision of data of an equivalent scientific quality.

6. The supervisory authority shall be informed of the more significant changes with regard to the type of fuel used or the mode of operation. The supervisory authority shall decide whether the provisions referred to in paragraphs 1 to 4 on monitoring continues to be adequate or must be adapted.

7. The continuous measurements carried out in accordance with paragraph 1 shall include the measurement of waste exhaust oxygen content, temperature, pressure and water vapour content. Continuous measurement of the water vapour content in the flue gas is not necessary, provided that the sampled exhaust gas is dried before the emissions are analysed.

8. Sampling and analysis, of relevant pollutants and measurement of operating parameters as well as quality assurance of automated measuring systems and reference methods of measurement used for the calibration of these systems shall be carried out in accordance with Cen standards. If CEN standards are not available, ISO standards, national or other international standards which will ensure the provision of information of an equivalent scientific quality shall apply. Quality assurance to be conducted each 5. year.

The automated measuring systems shall be subject to control by means of parallel measurements with the reference methods at least once a year.

The combustion plant shall inform the supervisory authority of the results of the testing of the automatic measurement systems.

9. With regard to the emission limit values, the values of the 95% confidence intervals in the context of a single measured result shall not exceed the following percentages of the emission limit values: carbon monoxide





10%







Sulphur dioxide





20%







Oxides of nitrogen





20%







Dust





30%





 

 









10. The validated average values per hour and per day is determined from the measured valid hourly average values after the deduction of the value of the confidence interval specified in point 9.

Days on which more than three hourly average values are invalid due to the automatic measuring system is not functioning properly or is under maintenance and is not validated. If more than ten days over a year not be validated due to such circumstances, the supervisory authority requires that the combustion plant shall take appropriate measures to make it automatic measurement system more reliably.



Annex 4 Assessment of compliance with emission limit values

1. When carrying out continuous measurements, the emission limit values shall be considered in parts 1 and 2 for compliance, when an assessment of the measurement results for the operating time within one calendar year show that all the following conditions are met: (a)) No validated monthly average values exceeds the relevant emission limit values as laid down in annexes 1 and 2.



(b)) No validated daily average values exceeds 110% of the relevant emission limit values as laid down in annexes 1 and 2.



c) No validated daily average values for combustion plants, consisting solely of coal-fired boilers with a total rated thermal input below 50 MW, exceeds 150% of the relevant emission limit values as laid down in annexes 1 and 2.



d) 95% of all the validated hourly average values over the year do not exceed 200% of the relevant emission limit values as laid down in annexes 1 and 2.

The validated average values shall be determined as defined in annex 3, paragraph 10.

In cases where only discontinuous measurements or other appropriate required procedures for the determination of emissions, shall be considered emission limit values set out in annexes 1 and 2 to be complied with if the results of each of the series of measurements or of the other procedures defined and determined in the permit, do not exceed the emission limit value.



Annex 5-Reporting

For combustion plants covered by this Ordinance must the combustion plant on the basis of the rules on aggregation in section 3 for each combustion plants once a year, not later than 1 July. February, send a statement to the supervisory authority containing: 1. Combustion plant's total rated thermal power (MW).



2. Type of combustion plants: boiler, gas turbine, gas engine, diesel engine, other (Please specify type).



3. Start date of the operation of the combustion plant.



4. The total annual emissions (tonnes/year) of sulphur dioxide, nitrogen oxides and dust (as total suspended particles).

Annex 6 average emission limit values for combustion plants

(A).

For mixed combustion plants, which use two or more fuel types at the same time, the competent authority shall set the emission limit values set out in the following steps: 1. As a starting point, use the emission limit value for each fuel type and for each pollutant, that corresponds to the entire plant's total rated thermal power, as specified in annexes 1 and 2.



2. The fuel-weighted emission limit values, shall be determined by multiplying each of the in no. 1 referred to emission limit values by the thermal power from each fuel type, and divide the result by each multiplication with the sum of the thermal power from all fuel types.



3. The fuel-weighted limit values are added together.

(B).

In the case of mixed combustion plants covered by section 4, using the distillation and conversion residues from refining of crude oil for its own consumption, either alone or with other fuels, the following emission limit values can be used instead of the emission limit values set out in paragraph (A): 1) If the dominant fuel type's share of the sum of the thermal inputs delivered by all fuels, when the combustion plant is in operation, is 50% or more , the emission limit value laid down in annex 1 of the determinative fuel.



2) If the dominant fuel type's share of the sum of the thermal inputs delivered by all fuels is less than 50%, the emission limit value, which is determined in accordance with the following steps:



(a)) The emission limit values set out in annex 1, shall be used for each of the used fuel types corresponding to the combustion plant's total rated thermal power.



(b)) the emission limit value of the determinative fuel is calculated by multiplying the emission limit value that is specific for this type of fuel in accordance with subparagraph (a), by a factor of two and know from this result to pull the emission limit value of the used fuel, which has the lowest emission limit value, see. Annex 1, which corresponds to the combustion plant's total rated thermal power.



(c)) The weighted emission limit value for each type of fuel used is determined by multiplying the limit value, which is determined in accordance with subparagraphs (a) and (b) with the thermal power from the fuel type and by dividing the result of this multiplication with the sum of the thermal inputs delivered by all fuels.



(d)) The weighted emission limit values, which is determined in accordance with subparagraph (c) shall be added together.

(C).

In the case of mixed combustion plants covered by section 4, using the distillation and conversion residues from refining of crude oil for its own consumption, either alone or with other fuels, the following average emission limit values for sulphur dioxide is used instead of the emission limit values set out in points (A) and (B):

Average emission limit values (mg/normal m3) for SO2 for mixed combustion plant in refineries, with the exception of gas turbines and gas engines, which alone or in combination with other fuels used the distillation and conversion residues from crude-oil refining for own consumption: a) For combustion plants, which were approved prior to the 27. November 2002, or if the combustion plant before that date had submitted a complete application for authorisation, provided that the plant was in operation no later than 27 per. November 2003:1000 mg/normal m3.



(b)) For other combustion plants: 600 mg/normal m3.

These emission limit values shall be calculated at a temperature of 273.15 K, 101.3 kPa and after one press of the correction for the water vapour content in the flue gas, as well as by a standardized O2 content 6% for solid fuels and 3% for liquid and gaseous fuels.
