  3. c)by determining the fuel-weighted emission limit values, which are obtained by multiplying the calculated fuel emission limit value by the thermal input of the determinative fuel and other individual emission limit values by the thermal input delivered by each fuel, the product of multiplication being divided by the sum of the thermal inputs delivered by all fuels; and (

For single gas turbines not falling into any of the above categories, but having an efficiency greater than 35% (determined at ISO base load conditions), the emission limit value shall be 1.42 where  is the gas turbine efficiency expressed as a percentage (and at ISO base load conditions). Gas turbines for emergency use that operate less than 500hrs per year are excluded from these limit values. The operator of such plants is required to submit each year to the competent authority a record of such used time.

(6)Notification of a temporary derogation from compliance with Large Combustion Plants Emission Limit Values. In view of the written request by [person submitting the request] on behalf of [operator], dated [date], I [Name of Director], in my capacity as Director of Environment Protection have examined all the information handed by [operator] together with the above mentioned request and have decided to allow for a derogation from [type of derogation to be applied to plant] for the [name of the plant] operated by [name of operator] having its registered address at [registered address of the operator] and subject to the IPPC Permit [IPPC permit number] issued on the [date of issue of the permit] for a period not exceeding [time]. This derogation is subject to the following conditions: [Signature] [Name, SURNAME] Director of Environment Protection Attached a copy of the request for derogation and technical information related to the case. [ S.L.549.56 20 LARGE COMBUSTION PLANTS SCHEDULE IX REQUIREMENTS FOR THE AUTOMATED MEASURING SYSTEMS AND FOR THE VALIDATION OF RESULTS The value of the 95% confidence interval of a single measured result shall not exceed the following percentages of the emission limit values: Sulphur dioxide Nitrogen oxides Total dust 20% 20% 30% The validated hourly and daily mean values shall be determined from the measured hourly average values after having subtracted the value of the confidence interval specified above. Any day in which more than three hourly average values are invalid due to malfunction of the automated measuring system shall be invalidated. If more than 10 days a year are invalidated for such situations, the competent authority shall require the operator to take adequate measures to improve the reliability of the automated measuring system. SCHEDULE X INFORMATION TO BE REPORTED WITH THE EMISSIONS INVENTORY Emissions inventories prepared by the operator under regulation 17, shall include the following information: 1 Name of the Installation; 2 Name of the combustion plant; 3 Fuel Burn for the combustion plant (Mg.yr-1) 4 Heat Value of the fuel fired by the combustion plant (GJ.Mg -1) 5 Total annual load of sulphur dioxide for the combustion plant (Mg.yr-1). 6 Total annual load of nitrogen oxides for the combustion plant (Mg.yr-1). 7 Total annual load of dust for the combustion plant (Mg.yr-1). Total annual pollutant loads shall be calculated as follows: d=365  avg (WGFd  [P]d ) [for leap years d=366] d=1 Where: WGF d is the daily waste gas flow rate in Nm 3 [P]d avg is the daily average concentration of the pollutant in mg.Nm -3.
