  "text": "(1) The formula (mixing rule) in sub-paragraph (2) is to be applied whenever a specific total emission limit value ‘C’ has not been set out in a table in this Chapter.\n(2) The emission limit value for each relevant polluting substance and CO in the waste gas resulting from the co-incineration of waste is to be calculated as follows—\nVwaste×Cwaste±Vproc×CprocVwaste±Vproc=C\n(3) In this Chapter—\n“Vwaste” means—\n(a)waste gas volume resulting from the incineration of waste only determined from the waste with the lowest calorific value specified in the permit and standardised at the conditions given by this schedule,\n(b)where the resulting heat release from the incineration of hazardous waste amounts to less than 10% of the total heat released in the waste incineration or co-incineration plant, Vwaste must be calculated from a (notional) quantity of waste that, being incinerated, would equal 10% heat release, the total heat release being fixed.\n“Cwaste” means emission limit values for waste incineration plants set out in Chapter 3,\n“Vproc” means waste gas volume resulting from the plant process including the combustion of the authorised fuels normally used in the plant (wastes excluded) determined on the basis of—\n(a)oxygen contents at which the emissions must be standardised as set out in these regulations,\n(b)where not provided for within these regulations, the real oxygen content in the waste gas without being thinned by addition of air unnecessary for the process,\n“Cproc” means—\n(a)emission limit values as set out in this Chapter for certain industrial activities,\n(b)in the absence of the values in (a), emission limit values of plants which comply with these regulations for such plants while burning the normally authorised fuels (wastes excluded),\n(c)in the absence of the values in (a) or (b), the emission limit values set out in the permit,\n(d)in the absence of the values in (a), (b) or (c), the real mass concentrations,\n“C” means—\n(a)total emission limit values at an oxygen content as set out in this Chapter for certain industrial activities and certain polluting substances,\n(b)in the absence of such values, total emission limit values replacing the emission limit values as set out in schedules 21-24,\n(c)where the total oxygen content to replace the oxygen content for the standardisation is to be calculated on the basis of the content above respecting the partial volumes,\n(d)all emission limit values are to be calculated at a temperature of 273.15K, a pressure of 101.3kPa and after correcting for the water vapour content of the waste gases.",
