  "text": "The following Annex XIX is added:\n‘ANNEX XIX\nActivity-specific guidelines for the production of soda ash and sodium bicarbonate as listed in Annex I to Directive 2003/87/EC\n1.\nBOUNDARIES AND COMPLETENESS\nThe activity-specific guidelines in this Annex shall be applied for emissions from installations for the production of soda ash and sodium bicarbonate as listed in Annex I to Directive 2003/87/EC.\n2.\nDETERMINATION OF CO2 EMISSIONS\nIn installations for the production of soda ash and sodium bicarbonate emission sources and source streams for CO2 emissions include:\nfuels used for combustion processes, e.g. with the purpose of producing hot water or steam,\nraw materials (e.g. vent gas from calcination of limestone, to the extent it is not used for carbonation),\nwaste gases from washing or filtration steps after carbonation, to the extent they are not used for carbonation.\n2.1.\nCALCULATION OF CO2 EMISSIONS\nAs soda ash and sodium bicarbonate contain carbon stemming from the process inputs, the calculation of process emissions shall be based on a mass balance approach pursuant to Section 2.1.1. Emissions from the combustion of fuels can either be monitored separately pursuant to Section 2.1.2 or be taken into account in the mass balance approach.\n2.1.1.\nMASS-BALANCE APPROACH\nThe mass-balance approach shall consider all carbon in inputs, stocks, products and other exports from the installation to determine the level of emissions of greenhouse gases over the reporting period, except for emission sources monitored in accordance with Section 2.1.2 of this Annex. The amount of CO2 used for producing sodium bicarbonate from soda ash shall be considered as emitted. The following equation shall be used:\nCO2 emissions [t CO2] = (input – products – export – stock changes) * conversion factor CO2/C\nWith:\n— input [t C] all carbon entering the boundaries of the installation,\n— products [t C] all carbon in products and materials, including by-products, leaving the boundaries of the installation,\n— export [t C] carbon exported from the boundaries of the installation in liquid and/or solid phases, e.g. discharged to sewer, deposited into landfill or through losses. Export does not include the release of greenhouse gases or carbon monoxide into the atmosphere,\n— stock changes [t C] stock increases of carbon within the boundaries of the mass balance.\nThe calculation shall then be as follows:\nCO2 emissions [t CO2] = (Σ (activity datainput * carbon contentinput) – Σ (activity dataproducts * carbon contentproducts) – Σ (activity dataexport * carbon contentexport) – Σ (activity datastock changes * carbon contentstock changes)) * 3,664\nWith:\n(a)\nactivity data\nThe operator shall analyse and report the mass flows into and from the installation and respective stock changes for all relevant fuels and materials separately. Where the carbon content of a mass flow is usually related to energy content (fuels), the operator may determine and use the carbon content related to the energy content [t C/TJ] of the respective mass flow for the calculation of the mass balance.\nTier 1\nActivity data over the reporting period are determined with a maximum uncertainty of less than ± 7,5 %.\nTier 2\nActivity data over the reporting period are determined with a maximum uncertainty of less than ± 5 %.\nTier 3\nActivity data over the reporting period are determined with a maximum uncertainty of less than ± 2,5 %.\nTier 4\nActivity data over the reporting period are determined with a maximum uncertainty of less than ± 1,5 %.\n(b)\ncarbon content\nTier 1\nThe carbon content of input or output streams is derived from reference emission factors for fuels or materials named in Section 11 of Annex I or in other activity-specific Annexes to these Guidelines. The carbon content is derived as follows:\nC content [t/t or TJ] = Emission factor [t CO2/t or TJ]/3,664 [t CO2/t C]\nTier 2\nThe operator applies country-specific carbon content for the respective fuel or material as reported by the respective Member State in its latest national inventory submitted to the Secretariat of the United Nations Framework Convention on Climate Change.\nTier 3\nThe carbon content of input or output stream shall be derived following the provisions of Section 13 of Annex I in respect to representative sampling of fuels, products and by-products, the determination of their carbon contents and biomass fraction.\n2.1.2.\nCOMBUSTION EMISSIONS\nEmissions from combustion of fuels shall be monitored and reported in accordance with Annex II, unless they are taken into account in the mass balance under Section 2.1.1.\n2.2.\nMEASUREMENT OF CO2 EMISSIONS\nThe measurement guidelines contained in Annexes I and XII shall be applied.",
