So the 95 % confidence intervals of a single measured result for the daily average value at the measuring of the Carbon monoxide shall not exceed 5 mg/m3. 27 Annex № 4 to Article 25, paragraph 3 EMISSION LIMIT VALUES FOR DISCHARGES OF WASTE WATER FROM THE CLEANING OF EXHAUST GASES Table 1 № Pollutants Emission limit values * 95% 100% 1 Total suspended solids 30 45 2 Mercury and its compounds, expressed as mercury (Hg) 0.03 3 Cadmium and its compounds, expressed as cadmium (Cd) 0.03 4 Thallium and its compounds, expressed as thallium (Tl) 0.05 5 Arsenic and its compounds, expressed as arsenic (As) 0.15 6 Lead and its compounds, expressed as lead (Pb) 0.2 7 Chromium and its compounds, expressed as chromium (Cr) 0.5 8 Copper and its compounds, expressed as copper (Cu) 0.5 9 Nickel and its compounds, expressed as nickel (Ni) 0.5 10 Zinc and its compounds, expressed as zinc (Zn) 1.5 11 Dioxins and furans, defined as the sum of the individual dioxins and furans ** 0.3 * The ELV are expressed in mass concentrations for unfiltered samples: • in mg/l for the pollutants in rows 1-10; • in ng/l for dioxins and furans in row 11. ** Calculated according to Annex № 6. 28 Annex № 5 to Article 45, paragraph5 FORMULA TO CALCULATE THE EMISSION CONCENTRATION AT THE STANDARD PERCENTAGE OXYGEN CONCENTRATION The measured emission value shall be reduced to the standard percentage oxygen concentration in the exhaust gas according the following formula: Em Om Os Еs × − − = 21 21 , Еs calculated emission concentration at the standard percentage oxygen concentration; Еm measured emission concentration; Оs standard oxygen concentration according to Article 45; Оm measured oxygen concentration. 29 Annex № 6 to §. 1, point 8 EQUIVALENCE FACTORS FOR DIBENZO-P-DIOXINS AND DIBENZOFURANS For the determination of the total concentration (TE) of dioxins and furans, the mass concentrations of the following dibenzo-p-dioxins and dibenzofurans shall be multiplied by the following equivalence factors before summing: Table 1 № Chemical compound Toxic equivalence factor 1 2,3,7,8 - Tetrachlorodibenzodioxin (TCDD) 1 2 1, 2,3,7,8 - Pentachlorodibenzodioxin (PeCDD) 0.5 3 1,2,3,4,7,8 - Hexachlorodibenzodioxin (HxCDD) 0.1 4 1,2,3,6,7,8 - Hexachlorodibenzodioxin (HxCDD) 0.1 5 1,2,3,7,8,9 - Hexachlorodibenzodioxin (HxCDD) 0.1 6 1,2,3,4,6,7,8 - Heptachlorodibenzodioxin (HpCDD) 0.01 7 - Octachlorodibenzodioxin (OCDD) 0.001 8 2,3,7,8 - Tetrachlorodibenzofuran (TCDF) 0.1 9 2,3,4,7,8 - Pentachlorodibenzofuran (РеCDF) 0.5 10 1,2,3,7,8 - Pentachlorodibenzofuran (РеCDF) 0.05 11 1,2,3,4,7,8 - Hexachlorodibenzofuran (НхCDF) 0.1 12 1,2,3,6,7,8 - Hexachlorodibenzofuran (НхCDF) 0.1 13 1,2,3,7,8,9 - Hexachlorodibenzofuran (НхCDF) 0.1 14 2,3,4,6,7,8 - Hexachlorodibenzofuran (НхCDF) 0.1 15 1,2,3,4,6,7,8 - Heptachlorodibenzofuran (НрCDF) 0.01 16 1,2,3,4,7,8,9 - Heptachlorodibenzofuran (НрCDF) 0.01 17 - Octachlorodibenzofuran (ОCDF) 0.001 30
