Illustrations 4 Executive Summary This project has been started as an initiative by Arctic Contaminants Action Program, ACAP, Project Steering Group on Reduction/Elimination of Emissions of Dioxins and Furans in the Russian Federation with Focus on the Arctic and Northern Regions Impacting the Arctic. Client is NEFCO. The objective of this work is to demonstrate possibilities to implement environmentally sound and economically effective projects in Russia within the framework of the Stockholm Convention on Persistent Organic Pollutants (POPs). In this investigation, Vorkuta cement plant has been selected as a suitable pilot site. After installation of an electrostatic precipitator (ESP), reduction of particular matter emissions (including black carbon, as soot equivalent) was shown by Rosprirodnadzor to be effective. Estimation of the emission factor of the Vorkuta cement plant for wet process operating kilns after ESP installation showed that plant emissions meet the requirements set by Rosprirodnadzor. The negative impact on Barents environment is likely to be reduced. Applying the alternative fuels has not lead to exceeding the emission requirements on Dioxins and Furans as stated in the 2000/76/EC directive of the European parliament and of the council of 4 December 2000 on the incineration of waste. 5 1 Introduction 1.1 Background Vorkuta Cement Plant (VCP) is the only cement producing facility in the Republic of Komi RF. The facility is located above the Arctic Circle, 25 km north of the town of Vorkuta. The nearest residential area is the settlement of Tsementnozavodskoy located 780 m south-east of the industrial site. The facility is located in the Bolshezemelskaya tundra in the permafrost zone and the surrounding land is thus not used for any agricultural purposes. Construction of the plant started in 1947 and its design was developed by the Lengiproshakht Institute. The first processing line with an estimated production capacity of 25.0 thousand tons of cement per year was in operation as early as September 15, 1950. According to the SanPin 2.2.1/2.1.1.1200-03 (revised version) classification, the production of cement (Portland – iron-Portland – pozzolana cement, etc.), as well as local cements (brick cement, Roman cement, gypsum-slag cement, etc.) may be classified as hazard class II facility with a 500-m sanitary protection zone (section 7.1.4. item 1). In terms of emissions, cement production belongs to the category II facilities of (the category was determined according to the document (OAO NII Atmosphera/ SRI Atmosphere JSC, St. Petersburg, 2012). The VCP industrial site general map is given in Figure 1, the schematic map of pollution sources is given in Figure 2. 6 Figure 1 The VCP industrial site general map 7 Figure 2 Schematic map of the atmospheric air pollution sources 8 This investigation was initiated by the ACAP Expert Group on “Reduction/Elimination of Emissions of Dioxins and Furans in the Russian Federation with focus on the Arctic and northern regions impacting the Arctic”. The main reasons for the investigation were: To assess the effectiveness of installed filters on the reduction of dioxin emissions into the atmosphere To assess the effects on the emission of dioxins resulting from introduction complementary fuels into the process To assess the compliance of atmospheric pollutant emissions by Vorkuta Cement Plant with reference to relevant national and international standards and regulations. Work was carried out under the Agreement with NEFCO of June 4, 2014 including: 1. Sampling of pollutant emissions into the atmospheric air after ESP EGBM1-25-96-4 electric filter installation: - in the course of using conventional fuels, - in the course of using complementary fuels (waste). The parameters and characteristics of pollutants measured as well as performance requirements are given in Appendix 1 “The parameters and characteristics of pollutants for using in sampling and analyzing pollutant emissions by Vorkuta Cement Plant into the atmosphere according to the ACAP Working Group requirements for dioxins and furans.” Work plan for sampling performed by the SPA Typhoon experts is given in Appendix 2. 2. Chemical analyses of collected samples by the SPA Typhoon. 3. Assessment of the results obtained. 1.2 Characteristics and current status of Vorkuta Cement Plant The facility has totally 3 rotary kilns adapted for a wet process. The kiln # 2 is 89 meter long. Exhaust gas from rotary kiln # 2 is delivered to the ESP filter and finally transferred to having a smoke pipe with a diameter of 3.60 m in the pipe orifice is operated at the sampling site of Ø 2.19 m and a height of 90 m. The ESP filter (ESP EGBM1-25-9-6-4) was installed in August 2013. 9 The kiln has the environmental pollution source number 0004 in the schematic map (Figure 2). The kiln was fed with coal from the Vorgashorskaya mine (coal brand is GZhO, grade is SSh, certificate of coal quality is given in Appendix 3). Annual amount of cement production at VCP is 450000t at 2013-2014. 10 2 Organization and sampling procedures 2.1 Gas phase samples for PCDD/PCDF analyses The gas phase samples were collected using the SS-1 device on September 3 to 6, 2014. Sampling location is presented on figure 3. Sampling, summarised in Table 1 was carried out on four consecutive days: 03.09.2014 – samples 1 and 2 collected from 15:10 to 18:10. The samples were collected in the course of conventional fuel combustion, coal. 04.09.2014 – samples 3, 4, 5 collected from 9:50 to 14:00. Coal was combusted in the kiln. Sample 6 is a mix of dust samples collected from the ESP during 24 hour with 1 hour interval. 05.09.2014 – samples 7, 8 and 12 collected from 15:10 to 19:10. The samples were collected in the course of conventional and complementary fuel joint combustion. 06.09.2014 – samples 9, 10 collected 9:50 to 13:30. The samples were collected in the course of conventional and complementary fuel joint combustion. Sample 11 is a mix of dust samples collected from the ESP during 24 hour with 1 hour interval. Each sample collected for PCDD/PCDF analyses consists of three parts: aerosol filter, condensate and sorbent XAD-2. Extract from these samples has been obtained and kept in the sealed ampule. Preserved by this way samples have been moved to SPA Typhoon for further processing. Samples 5, 10, 6 (part of sample) and 11 (part of sample) have been sent to Sweden for the parallel analysis for verification of analyses of SPA Typhoon. Samples 2 and 7 (gas) have been used also for determination of the soot content. 11 Figure 3 Scheme of sampling locations 12 Table 1 Sample # Characteristics from the sampling of gas phase and solid phase samples at VCP in September 2014 Date Fuel (1 = Sampling Volume Typhoon Codes on coal, 2 = duration (h) sampled, sample code samples sent coal + Nm 3 to Sweden tires/ sleepers) 1 03.09.14 1 1h 30min 2.52 165-09-14 - 2 03.09.14 1 1h 30min 2.27 166-09-14 - 3 04.09.14 1 1h 20min 2.025 - - 4 04.09.14 1 1h 20min 2.7 167-09-14 5 04.09.14 1 1h 30min 3.6 - 5 (e+f) 6 (dust) 04.09.14 1 24 h 50 (cm3) 171-09-14 6 7 05.09.14 2 1h 20min 2.7 168-09-14 - 8 05.09.14 2 1h 20min 2.7 169-09-14 - 9 06.09.14 2 1h 50min 2.7 170-09-14 - 10 06.09.14 2 1h 50min 2.7 - 10 (e+f) 11 (dust) 06.09.14 2 24h 50 (cm3) 172-09-14 11 12 05.09.14 2 1h 20min 2.7 - - 13 Figure 4 The process of sampling All process of samples analysing have been done according the document "Methods of measurement of the total content of polychlorinated dibenzo-p-dioxins and dibenzofurans in terms of 2,3,7,8-tetrachlorodibenzo-p-dioxin in samples of industrial emissions into the atmosphere by gas chromatography-mass spectrometry" (PND F 13.1.65-08). This method is allowed for the purpose of state environmental control. It is based on the capture of PCDD / PCDF from gaseous emissions into the atmosphere by aerosol quartz filters and polymeric sorbent XAD-2. Features of this method are described below. Sorption material is coated by isotopically labelled standard PCDD / PCDF compounds (SIS) for quality control of sampling and subsequent quantitative calculations. The filters are extracted with organic solvent. Compounds interfering with PCDD / PCDF determination are removed from the extracts. The isotopically labelled internal standard (RIS) is added and the extracts are concentrated. After that the content of PCDD / PCDF is determined by a combination of high performance capillary gas chromatography and mass spectrometry. Sampling is done by pumping air through a heated aerosol filter, system of traps and XAD-2 sorbent. The sample volume is 2-10 m3. Sampling scheme is given in Figure 5. 14 Figure 5 Sampling setup scheme 1 - nozzle, 2 - thermocouple, 3 - Pitot tube, 4 - probe body, 5 – flow meter (or oxygen analyser), 6 - aerosol filter thermostat 7 - filter holder, 8 - temperature tester and regulators, 9 - thermostat liquid traps 10 - liquid traps 11 - sorbent XAD-2 cartridge, 12 - receiver, 13 - gas flow meter, 14 – pump The exposed aerosol filter is folded (front layer should be covered) and placed into aluminium foil package and the XAD-2 cartridge with is hermetically closed. Trapped content is transferred into a glass flask and each trap is cleaned twice with acetone. The acetone washings are combined with the condensate. Condensate is stored at 4°C without sunlight access. Samples are allowed to transport at room temperature (duration of transportation should be less 3 days). 2.2 Dust sampling Solid particles (samples 6 and 11) were sampled selectively at intervals of 1 hour during two days. These samples have been collected from the ESP (see sample location on Figure 3). Mixed samples have been prepared from the material collected during 24 hours. Two volumes of 50 cm3 for analysis have been taken from each mixed sample. Sample 6 has been collected during the pure coal combustion and sample 11 has been 15 collected during combustion of coal with wastes. These samples have been analyzed on content of heavy metals and content of PCDD / PCDF. 2.3 Sampling for other pollutants Samples 2 and 7 have been analyzed for content of soot. Soot content has been determined according to “Methods of measurements of mass concentration of soot in industrial emissions and work area air FR.1.31.2001.00384) 2.4 Gas flow sampling Gas velocity at the point of sampling was measured during the sampling periods by Pitot tube. The results of these velocity studies are given in Table 2. The scheme of sampling and velocity distribution in the gas duct is given below in Figure 6 and Figure 7. Distance between test points did not change during sampling. Since the velocity field from point 2 to point 3 may change due to a change in the pipe direction and sampling from point 1 is a more or less constant value, an approximation for point 1 was given for calculations. The point of 10 cm was omitted as a nearboundary phenomenon.

It means that samples were split into filter and condensate and the results are shown as the sum of the two parts. The analysis was performed in the mass spectrometry system. We use high-resolution chromatography mass spectrometer with double focusing DFS (Figure 8). Figure 8 High resolution mass spectrometer DFS This device is built on a modern platform. Novelty is provided by high sensitivity, low detection limits and high level of automation. The design of the device ensures no aberrations of the image in the analyser. This is achieved by double focusing system based on high precision toroidal electrostatic and magnetic analysers. Method described in document RD 52.04.186-89, App. 5.3.8 part.

Waste is used as complementary fuel (Appendix 4a): 57500203 13 00 4 – used fabric cord tires (composition: chemical rubber – 88%, textiles – 12%); 57500204 13 00 4 – used metal cord tires (composition: chemical rubber – 87.65%, metal – 7.60%, textiles – 4.85%); 27 17120600 13 01 3 – used and sorted out timber railway sleepers impregnated with antiseptics (composition: timber – 90%, impregnating compound – 10%). The use of these complementary fuels in cement kilns is permitted and regulated by GOST R 55099 – 2012 “Efficient Use of Resources” – item 4.2.4.1. The existence of this document does not require a special permit to use the above waste as a complementary fuel. Complementary fuels, not exceeding 5%, were delivered to the auxiliary kiln feed every hour. So, every hour 0.1 t of complementary fuel (consisting of 0.085 t of sleepers and 0.015 t of tires) and 1.9 t of coal were fed to the kiln. 3.2 Dioxins and furans (PCDD/PCDF) Analysis of dioxins and furans in gas and dust samples were performed by SPA Typhoon and additional analyses were performed by Umeå University, Sweden. 3.2.1 Analytical result of SPA Typhoon The content of PCDD and PCDF was measured in samples 1, 2, 4, 6, 7, 8, 9, 11 (Protocols ## 165-09-14, 166-09-14, 167-09-14, 171-09-14, 168-09-14, 169-09-14, 17009-14, 172-09-14 respectively. Samples 6 and 11 are dust, PCDD and PCDF was measured according TOR). Samples 5 and 10 have been collected and sent to Sweden for the parallel analyzes. Samples 3 and 12 collected for the reserve. Dioxin equivalent (DE) is indicated in terms of TEQ (Toxic Equivalency). To obtain the TEQ content in a dioxin mixture, the amount of each congener in the mixture is multiplied by its TEF according to Table 6. The sum of these products gives the total TEQ of the sample. System I-TEQ has been used for the analyses.

However, the EU Directive 2000/76/EC require that emissions for cement plants with co-incineration of waste is normalised to an oxygen content of 10%. Consequently data normalised to 11% and 10%, respectively, has been calculated. The content of PCDD/Fs normalised to 11% oxygen was calculated as: C (11%) = Cn (20.95-11)/(20.95-[O2]), C (11%) - normalized concentration of PCDD/Fs, Cn – measured concentration in a real situation [О2]– concentration of oxygen in the rotary kiln during sampling (Content of the oxygen into the atmospheric air = 20.95) Calculation of concentration PCDD/Fs from 11% O2 to 10% O2 by volume was performed according to: C (10%) = C (11%) 10.95/9.95 Data of samples presented in Table 7 also have been normalized for pressure and temperature. To correct for temperature: QnormT = Qcorr × (273/(273+ Tm)) Where: QnormT is the normalized volumetric flowrate for temperature Tm is the measured temperature in degrees centigrade To correct for pressure: Cnorm = CnormT × (Pm /101.3) Where: Cnorm is the normalized volumetric flowrate Pm is the measured pressure in kPa (1 kPa =7,500637654192ppm) 29 Table 7 Results of PCDD/PCDF analysis of gas samples from SPA Typhoon Results from SPA Typhoon.

Table 10 shows that all emissions after ESP filter installation is comparable with the default emission factor. 3.2.2 Analytical results of Umeå University Method description The methods applied for preparation, purification and analysis of samples are described 35 more in detail in the report from Umeå University (Annex 4b). The methods used in the analysis are validated and proven in recurring international Inter-calibration studies. The analyses are performed according to Swedish and European Standards SS-EN 1948-2, -3 and -4. The technique is gas chromatography coupled to mass spectrometry (GC-MS). A summary of the methods is following below. Sample Preparation 13 C-labelled standards were added to the sample before extraction. These standards consist of isotopically labelled substances with the same characteristics as the subjects analysed, but with different molecular weight. The sample was then Soxhlet extracted with toluene for 16 hours. Sample Purification The clean-up of polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF) was performed, first by a multistep silica column, followed by a basic alumina column and finally on a carbon column. Analysis Isomer specific analysis was performed using gas chromatography (GC) coupled with mass spectrometry (MS). An MS (Waters Autospec Ultima) with high mass resolution was used. The separation of substances was consequently performed on the GC whereas the detection and quantification was performed with the mass spectrometer. In MS analysis, the substances with different atomic masses are detected in a selective way. This enables the use of synthetic 13 C isotopically enriched compounds, which were used as internal standards. Accordingly, a comparison of the response ratio between “natural” congeners and 13 C congeners in the sample with the corresponding ratio in the quantification standard, containing both known amounts of natural and added 13 C- congeners, was performed. Consequently, the results could easily be compensated for potential losses during clean-up. The measurement uncertainty is given in the analysis report is valid at the limit of 36 quantification (LOQ), defined as signals exceeding ten times above the noise level. In the analysis reports, the values for congeners where this criterion is not met, is given in italics. In the interval between three and ten times the noise level, measurement uncertainty is elevated but the values still provide valuable contributions to the results and the TEQ calculations. Calculation of the TCDD equivalents (TEQ) was performed as described for the samples analysed by Typhoon. In many cases all congeners cannot be detected or quantified and TEQ are therefore often calculated at three levels. A lower concentration limit (lower bound) where results below LOD are set to zero, a mean concentration (medium bound) where results below LOD are set to 1/2 LOD and an upper concentration limit (upper bound) where results below LOD is set to LOD in the calculation of TEQ. In cases where all congeners are detected the TEQ values from the three bound levels coincide. In the analysis report column called "I-TEQ", the percentage contribution to the total TEQ was calculated using the upper bound. Laboratory blank concentrations are reported separately, no subtraction is made from actual concentrations in the samples. Normalization has been made to the same unit as for the samples using the mean of the sample amounts in the series. The reference materials used in the analysis were the following: The internal standard, added to the sample prior extraction of the sample or for the extract that we received prior clean-up contained: 2,3,7,8 13C-TCDF 2,3,4,6,7,8 13C-HxCDF 2,3,7,8 13C -TCDD 1,2,3,4,7,8 13C-HxCDD 1,2,3,7,8 13C-PeCDF 1,2,3,6,7,8 13C-HxCDD 2,3,4,7,8 13C-PeCDF 1,2,3,7,8,9 13C-HxCDD 1,2,3,7,8 13C-PeCDD 1,2,3,4,6,7,8 13C-HpCDF 1,2,3,4,7,8 13C-HxCDF 1,2,3,4,7,8,9 13C-HpCDF 1,2,3,6,7,8 13C-HxCDF 1,2,3,4,6,7,8 13C-HpCDD 1,2,3,7,8,9 13C-HxCDF 13 C-OCDF and 13C-OCDD 37 Recovery standard which is added to the samples prior analysis on the GC/MS instrument were: 1,2,3,4 13C –TCDD; 1,2,3,4,6 13C-PeCDF; 1,2,3,4,6,9 13C-HxCDF; 1,2,3,4,6,8,9 13C-HpCDF and 1,2,3,4,6,7,8 13C-HpCDD. The measurement uncertainty for the analytical methods were determined according to the Eurachem/CITAC guide ”Quantifying uncertainty in analytical measurement”. The measurement uncertainty for combustion related samples was ±29%. Results The full results are given in Annex 4b. A compilation of the result is shown in Table 11, Table 12 and Table 13 below.

When comparing the dioxin content in flue-gas as reported by Typhoon and Umeå it is noted that they are very close to each other. The range is 0.024 to 0.038 ng I-TEQ/Nm3 without any trend to whether complementary fuels were mixed with the coal or not. The levels are normal with respect to the process but there are also many examples of cement industries that show considerably lower emission levels. So even if the absolute dioxin emission level seems to be within the “normal” range, there could be possibilities for further reductions. The analytical results on dioxins in the particulate (dust) fraction sampled show some similarities. The fact that the concentrations reported by Umeå is 15 to 25 times lower than those reported by Typhoon could be a result from that both calculations are based on lower bound estimates. This means that results on all congeners below LOD are set to zero. The LODs reported by the laboratories differ a lot and this could be the main reason to the discrepancies. In fact, when medium bound (LOD/2) concentrations are calculated the results from Typhoon and Umeå on sample 6 are 1.0 and 0.8 pg/g, respectively and the corresponding results from sample 11 are 1.4 and 2.5 pg/g, respectively. It could also be noted that the results coincides with respect to that lower concentrations are reported from coal + complementary fuel than coal alone. Of course no certain conclusion can be drawn on this based on this limited number of samples. On the other hand the results don’t give indications that coal + complementary fuel could cause increased formation of dioxins. 39 3.3 Heavy metals Although initially envisaged, heavy metals emissions from cement kiln # 2 have not been calculated nor measured prior to the ESP installation in 2014. Besides, the pollutant emission permit does not contain these substances. The report assesses the current situation as of the time of study of September 3-6, 2014. The content of heavy metals in the solid residue was measured in samples 6 and 11 (collected from the ESP dust collector). As pointed out above, sample 6 was collected in the course of conventional fuel combustion, coal, while sample 11 – in the course of coal and complementary joint fuel combustion. The results of analysis are given in Table 14. Table 14 Results from quantitative chemical analysis of metal content in samples (mg/kg dry weight) Sample # Pb Cd Sb As Cr Co Cu Mn Ni V Tl Hg 6 368 0.36 <1.00 37.2 80.8 4.45 103 415 58.0 90.7 0.74 0.062 11 557 0.29 <1.00 59.3 76.8 6.93 106 242 63.2 92.1 0.63 0.148 The results suggest potential emissions of heavy metals during the cement production at VCP. Most of heavy metals tend to get oxidized or adsorbed by particulate matter, and then trapped by ESP. However, at the working kiln temperatures mercury in gaseous form is generally emitted into the atmosphere passing by the ESP with low capture, thus the numbers presented should represent trace quantities of the metal only. Dust sample has been collected 13 November 2013 to determine the hazard class of the residue (waste) on the filter. 3rd hazard class has been defined by calculation method (see Appendix 6). The dust is recirculated and used as raw material for the cement production and the nonvolatile heavy metals (i.e. all except Hg) will ultimately end up in the produced cement. 40 3.4 Black carbon For the purposes of this study soot emissions were considered as equivalent of black carbon emissions in 1:1 ratio. There is no official definition of black carbon nor any related measurement/estimation methodology presently adopted in the Russian Federation. Moreover, terms ‘soot’ and ‘black carbon’ are used interchangeably in this paper. The content of black carbon in the gas duct after ESP EGBM1-25-9-6-4 was measured in samples 2 and 7. The results of soot content measurement are given in Protocol of quantitative chemical analysis # 173-098-14. Modelling of local dispersion of dust is further provided in section 4.2. Table 15 Results of soot (black carbon) test in exhaust gas samples Soot content No. Sample code (normalized to 10% of O2), mg/Nm3 1 2 Gas duct after ESP EGBM1 25-9-6-4. Sample No. 2 Gas duct after ESP EGBM1 25-9-6-4. Sample No. 7 Measurement error, % 0.135 2.0 0.347 2.0 Total emission of soot from the VCP: Sample No. 2 = 0.135 mg/Nm3×26.21 Nm3/s×3600×24/400.9 ton=762.57 mg/ton. Sample No. 7 = 0.347 mg/Nm3×26.85 Nm3/s×3600×24/400.9 ton=2007.94 mg/ton. According this data the emission of black carbon increases more than twice if the complementary fuel used. 3.5 Dust During the investigation on Vorkuta plant from 3 to 6 September the dust content in the samples was not determined. However there are some data in the materials provided by the Vorkuta cement plant administration. These data were obtained during ordinary inspections of emissions and preparation of the project of the limit emissions for Vorkuta 41 cement plant. Data from this project is used for the calculation of compensation value for environmental pollution. Table 16 shows the data of dust content analysis. Table 16 Emission of dust before and after installation of the electrostatic precipitator (ESP) Data for August 14, August 26, sampling 2013 2013 No Yes ESP installed Sampling g/s Emission, mg/m3 Emission, kg/h Yes Yes Before After ESP site Emission, November 12, 2013 After ESP ESP May 26, 2014 Yes Before ESP Yes After ESP 354.708 14.430 459.799 13.546 627.176 8.228 11381.45 334.87 - 662.49 17412.70 397.50 1276.940 51.950 48.765 29.620 76463.47 3110.78 2920.06 1773.65 Emission, mg/tonne cement produced * g/tonne *The output of cement is 16.7 t/h Total emission of dust from the VCP Annual emission of the dust in VCP has been defined during inventory of objects with emissions. Dust emissions (to 20% of SiO2) of 2013 were 129.816 tons according to the statistical reports of the plant. Annual cement production in 2013 was 160 000 tons. Thus, the dust emission per ton of cement was 129.816:160000 = 0.00081135 t/t and 811.35 g/t. This estimation based on the official statistic gives the most correct averaged value of dust emission per ton of produced cement. 42 Efficiency of ESP The air using in the manufacturing cycle is impossible to clean to original quality due to irreversibility of real process. Therefore, treatment facilities cannot protect the biosphere from industrial emissions. We can talk only about reduction of the contamination level. The sanitary-hygienic method is used for estimation of the efficiency of cleaning the air. It is based on a comparison of the level of achieved cleaning with established hygienic standards (the maximum permissible concentration). Tests November 12, 2013 showed that the rate of emission of dust reduced from 459.799 g/sec to 13.546 g/sec. The effectiveness of the filter was 97,05% Tests May 26 2014 showed the effectiveness of the filter 98,69%The actual amount of emission reduction of dust from the Vorkuta cement plant in 2013 (according to statistical reports) compared with 2012 was 7224.904 tonnes. Since the study of dioxins and furans performed only after the installation of the filter, the ecological efficacy of this action have been estimated only for inorganic dust (up to 20% SiO2), code 2909. Installation of ESP filter on the rotating kiln #2 at Vorkuta cement plant had to reduce emissions including inorganic dust (to 20% of SiO2). Relevance of this problem is caused by negative influence of SiO2 to the environment and human health. This substance is very dangerous for the human because leads to the silicosis. Silicosis is the most frequent lung disease, caused by inhalation of dust containing SiO2. The economic benefits for the plant are the reduction of the payments for air pollution. Modelling of local dispersion of dust is further provided in section 4.1. 43 4 Modelling of dispersion of pollutants 4.1 Modelling of local dispersion of dust Modelling based on emission data provided by VCP administration. This data have been obtained during ordinary inspections of emissions and preparation of the project of the limit emissions for Vorkuta cement plant for Rosprirodnadzor. Total emission during 4 days – 5 723 kg. Total cement production for the same period – 1 603.6 ton (1 603 600 kg). Volume of clinker activity 03.09.2014 – 400.6 t; 04.09.2014 – 403.3 t; 05.06.2014 – 398.3 t; 06.06.2014 – 401.4 t. Average volume of clinker activity over 400.9 t/day. Let us assess the change in inorganic dust concentration up to 20% of SiO 2 in the residential area and on the sanitary protection zone boundary after the filter installation.

Gross emissions were calculated according to “Guidelines on the Calculation, Regulation and Control of Pollutants Emissions into the Atmospheric Air”, item 1.4.2. Gross emission value (t/year) is determined using the formula: Myear = Mc ∙ t ∙ 3600 ∙ 10-9 t where Mc is an average intensity of this pollutant emission from the atmospheric pollution source in k-m mode of its operation, mg/s; t is an aggregate duration (hours) of the atmospheric pollution source operation in k-m mode during a year, t = 7080 hours. The figures of pollutant emissions given in Table 18 were included in the Pollutant Emission Permit (Rosprirodnadzor Order # 352 of 16.04.2014 as those achieved in 2013 and planned up to 2017 inclusively. The total volume of solid pollutant emissions was in 44 the amount of about 832 t/year; of inorganic dust – up to 20% of SiO2. Emissions of all compounds were included as MPE.

Inorganic dust emission amounted to 354708 mg/s at the pipe outlet in Protocol “Measurement of concentration of pollutants” # 04-ВХ-13 of August 14, 2013. The gas was not purified during the kiln operation (Appendix 5). Protocol “Measurement of concentration of pollutants” # 01-ВХ-13 of April 3, 2013 has dust emission from the rotary kiln of 329123 mg/s; an average value is 341912 mg/s. Figure 9 Inorganic dust emission before the filter installation 48 Let us determine the gross emission value (t/year) from the formula: Мyear = Мc ∙ t ∙ 3600 ∙ 10-9 where Мc is an average intensity of this pollutant emission from the atmospheric pollution source in k-m mode of its operation, mg/s; t is an aggregate duration (hours) of the atmospheric pollution source operation during a year in k-m mode during a year, t = 7080 hours. М year = 341912× 7080×3600×10-9 = 8 714653 t. Let us calculate the dispersion for inorganic dust concentration given in the above protocols. Automated calculation has been performed on PC following the unified computer program of calculation of ground level concentrations of pollutants in the atmospheric air UPRZA Ekolog agreed upon with A.I.Voeikov Main Geophysical Observatory. The program builder and holder is the Integral Firm (Saint Petersburg). Table 21 data permit to state that the filter installation on the rotary kiln # 2 gas duct allowed achieving the figures of inorganic dust content of MPC <1 on the sanitary protection zone and residential area boundary. This is the main criterion for the safe life of the population in the area since MPC is established by the state hygienic standards. The maximum permissible concentration (MPC) of a pollutant in the atmospheric air in population locations is the concentration that is not expected to cause negative effects on present or future generations during the entire life; does not reduce human performance nor deteriorate human health and sanitary living conditions. 4.2 Modelling of local dispersion of black carbon Soot emissions were measured in sample 2, coal combustion, and in sample 7, complementary fuel is used in the amount of not more than 5%. Data were obtained using the method described in RD 52.04.186-89, Annex 5.3.8 to part I, item 4.4; tool to be used carbon analyzer TOC-L CSN, module SSM-5000A (Appendix 5). The following results have been obtained: 49 Table 22 # 1. 2. Results of soot (black carbon) test in exhaust gas samples Soot content, Sample code mg/Nm3 Gas duct after ESP EGBM1 25-9-6-4.

The Russian legislation establishes MPC of 0.15mg/m3 in the area of population locations (GN 2.1.6.1338-03 “The maximum permissible concentration (MPC) of a pollutant in the atmospheric air in population locations”, Moscow, RF Ministry of Health, 2003 (as subsequently amended)). The current situation, which reflects the level of atmospheric air pollution without accounting for rotary kiln # 2 is given in Figure 10. The; calculations made show that the level of pollution in the residential area is 0 MPC without accounting for rotary kiln # 2. Let us make calculation including sample 2 and 7 emission assessments in the data available. In calculation we assume that the maximum soot content is 0.347 mg/m3. Calculation is made using UPRZA Ekolog program. Points indicated in Table 23 are assumed to be reference points. Data on the rest sources are included in Table 25 of calculation parameters based on MPE Project. The calculation results are shown in Table 24 and Figure 11.

The treatment efficiency was 98.7%. All calculations have been done according the respective guidance documents based on Russian Federation environment protection laws (see references: [2]-[12], [21]) 56 5 Conclusion The tests performed by Polar Foundation in VCP on September 3-6, 2014 to assess the emissions of dioxins and furans, soot (black carbon) and heavy metals showed as follows: 1. The installation of ESP EGBM1-25-9-6-4 electrostatic precipitator on the plant’s rotary kiln # 2 made it possible to reduce pollutant emissions into the atmospheric air. The actual amount of emission reduction of dust on the Vorkuta cement factory in 2013 (according to statistical reports) was 7224.904 tonnes (from 11216.754 tonnes to 3991.85). 2. No excess has been detected in the sum of 17 dioxin/furan compounds of the limits established by Directive 2000/76/EC of the European Parliament and of the Council “On the Incineration of Waste” requirements (Brussels, December 4, 2000) requirements for the emissions of this substance, 0.1×10-6 mg/m3, in all samples except for sample 2. In the day of sampling, coal was combusted in the kiln without adding complementary fuel. 3. Applying waste as alternative fuels has not lead to exceeding the emission requirements on Dioxins and Furans as stated in the directive 2000/76/EC of the European parliament and of the council of 4 December 2000 on the incineration of waste. 4. Emissions of heavy metals probably occur, especially in case of highly volatile mercury. Additional study / control should be considered. In addition, the results obtained from VCP statistics based on Rosprirodnadzor control, showed that: 5. emissions from Vorkuta Cement Plant comply with emission requirements currently applicable in the Russian Federation: 6. the filter installation on the rotary kiln # 2 smoke intake allowed achieving the figures of inorganic dust content of MPC <1 on the sanitary protection zone and residential area boundary. This is the main criterion for the safe life of the population in the area since MPC is established by the state hygienic standards; 57 7. when using complementary fuels, soot emissions on the sanitary protection zone boundary and near the residential area will not exceed established standards of 0.15 mg/m3. The results from the additional analyses conducted in the laboratory in Sweden (Umeå University) are comparable with the results from the sample analyses made in SPA Typhoon. So we made the conclusion that the technical, methodological capabilities of SPA Typhoon and qualifications of employees seem to fulfil the basic requirements that could be requested from a laboratory to be contracted for similar studies at industrial facilities in the Russian Federation. It is, however, noted that the laboratory could make its capacity more transparent by taking part in international inter-calibration exercises. 58 6 List of references Chief Medical Officer RF, 2007, “Sanitary protection zones and sanitary classification of facilities, buildings and other facilities”, SanPiN 2.2.1/2.1.1.1200-03.
