1 Introduction
Directive 2012/18/EU (also known as the SEVESO III directive) of the European Parliament on the control of major-accident hazards involving dangerous substances, amending and subsequently repealing Council Directive 96/82/EC was published on the 4th of July 2012. It is implemented in Ireland by the Chemicals Act (Control of Major Accident Hazards Involving Dangerous Substances) Regulations 2015 (also known as the COMAH Regulations). The SEVESO III Directive set out rules to achieve the prevention of major accidents involving dangerous substances, and seek to limit as far as possible the consequences for human health and the environment of such accidents.
Under Directive 2012/18/EU, dangerous substances are classified using the European Regulation (EC) No. 1272/2008 (CLP regulation herein) on the classification, labelling and packaging of substances and mixtures.
This report will identify the hazardous classification of various substances used at Boliden Mines and subsequently help define the requirements of the site with respect to SEVESO III.

2 Methodology
The substances at Boliden Mines which are the focus of this report are as follows:
- Copper sulphate (pentahydrate) (copper sulphate)
- Potassium isoamyl xanthate 90% (PAX)
- Sodium Ethyl Xanthate (SEX)
- Sodium Iso-Propyl Xanthate (SIPX)
- Zinc sulphate anhydrous, monohydrate (zinc sulphate)
- Sodium Cyanide
Each substance is diluted with water. This report helps determine the w/w percentage at which the new solution is no longer classified as a dangerous substance for the purpose of the SEVESO III Directive.
2.1 Ecological Toxicity Classification
Ecotoxicology data was obtained where possible from the relevant Safety Data Sheets (SDS), included in Attachments 1 - 4. In instances where data was insufficient, the ECHA substance database published by the European Chemicals Agency was used to obtain the relevant ecotoxicology data.
The dilution formulae for acute and chronic aquatic toxicity are displayed in Figures 2.1 and 2.2 respectively below as obtained from section 4.1.3.5.2 (a) & (b) of the CLP regulation.
The diluted mixture is then classified according to Table 4.1.0 of the CLP regulation (displayed on pg. 8 and 9 of this report) depending on the ecotoxicology data available.
Figure 4.1.2 from the CLP regulation (displayed below) displays the tiered approach to classification for acute and long-term aquatic environmental hazards. Adequate aquatic information was available (either from the SDS or ECHA) for all four substances, the summation method was only used in one instance where insufficient information was available.
Note: The Seveso III Directive applies the following:
Environmental Hazards Lower Tier Limit (tonnes)
Upper Tier Limit (tonnes)
E1 Hazardous to the Aquatic Environment in Category Acute 1 or
Chronic 1 100 200
E2 Hazardous to the Aquatic Environment in Category Chronic 2 200 500
Note: Additional additive rules apply as per Note 4 to Annex I of the Seveso III Directive.

*If a European Chemical Agency (ECHA) proposal dating to 2013 to reclassify copper sulphate is adopted, which is not yet the case, then this concentration of 7% could be reduced to 2.5%.
The implications of the above for Boliden Tara Mines are that the existing 160 m3 of copper sulphate solution at approx.10% concentration and the 22 m3 of zinc sulphate solution at approx. 9% would contribute to the Seveso calculation of the inventory of dangerous substances at the site. These two on their own would nearly exceed the E2 lower tier threshold of 200 tonnes, therefore leaving little remaining inventory allowance for other substances classified as an environmental hazard. By controlling the concentrations of the xanthate solutions, it should be possible to remain outside a Seveso III classification. One could also argue that reducing the copper sulphate concentration to less than 7% would remove it from consideration as a dangerous substance for the purpose of Seveso, but there is proposal by ECHA to reclassify copper sulphate, which if

adopted would reduce this percentage to 2.5%. Therefore, over the longer term there is some uncertainty with this option of maintaining below 7%.
If Boliden Tara Mines were to fall under the scope of the Seveso III Directive, it would be necessary to complete a risk assessment with respect to any scenarios which could lead to a potential Major Accident to the Environment (MATTE). With respect to the criteria set out in Annex VI of the Seveso Directive 2012/18/EC for notification of an accident to the European Commission it is considered that a release to the environment from any relevant scenarios, which would be identified, could fall under the following reportable category and constitute a Major Accident to the Environment (MATTE):
3. Immediate damage to the environment:
(a) permanent or long-term damage to terrestrial habitats:
(i)0,5 ha or more of a habitat of environmental or conservation importance protected by legislation;
(ii)10 or more hectares of more widespread habitat, including agricultural land;
(b) significant or long-term damage to freshwater and marine habitats:
(i)10 km or more of river or canal;
(ii)1 ha or more of a lake or pond;
(iii)2 ha or more of delta;
(iv)2 ha or more of a coastline or open sea;
(c)significant damage to an aquifer or underground water:
1 ha or more.

4 Calculations
4.1 Copper Sulphate (Pentahydrate)
4.1.1 Substance Information
100% copper sulphate has the following hazard phrases thereby placing it in the E1 classification category under the Seveso III directive:
- H400 Aquatic acute category 1
- H410 Aquatic chronic category 1
According to sections 4.1.2.7.1 & 4.1.2.7.2 of the CLP regulation, acute aquatic toxicity should be determined using a fish 96-hour LC50, a Crustacea species 48-hour EC50 and/or an algal species 72/96-hour EC50, whilst for chronic aquatic toxicity NOECs or other equivalent ECx values shall be used.
The following values were obtained from the SDS supplied by Boliden Harjavalta Oy:
- LC50 Fish (96hours) 0.17 mg/l
- LC50 Crustacea (48hours) 0.182 mg/l
From the ECHA CLH Report for Copper Sulphate Pentahydrate1, a proposal for a Harmonised Classification, pages 148 to 164 deal extensively with the issue of biodegradation of copper, of which some of the conclusions are summarised by the points below:
- The above findings for the generalized lake environment supports ”rapid removal of copper-ions,” equivalent to “biodegradation of organic substances”
- RMS is therefore of the opinion that copper fulfils the criteria of rapid removal, as more than 70% of copper is removed from the water column within 28 days.
It is therefore appropriate to assume that in the formula in Figure 2.2, copper sulphate can be treated as a rapidly biodegradable substance. Note: The proposal for a Harmonised Classification, which has not yet been formally adopted, proposes a revised chronic aquatic classification of:
- H411 Aquatic chronic category 2
Plus for environmental hazard acute category 1, H400, an M factor of 10 should be applied. The same ECHA report references numerous test results for copper sulphate and concludes that for the acute classification the relevant reference value is 0.073 mg/l and for the chronic classification the relevant reference value is 0.019 mg/l.
Therefore according to the criteria given in 4.1.0 (a) & (b)(ii) of the CLP regulation, obtaining an LC50 of > 1 mg/l and an NOEC value of >0.1 mg/l would classify the substance as category chronic 3, thereby removing it from the scope of Seveso III.

By using the additive formula in Section 4.1.3.5.2 of the CLP regulation, a concentration below 7% will remove a copper sulphate from the acute category 1, such that it will no longer be considered for Seveso III in this category. However, there is also a proposal, not yet adopted by the EU, to apply an M factor of 10 for copper sulphate. If this was to occur in the future, the following summation formula from Section 4.1.3.5.5 of the CLP regulation would apply and as such then, the relevant concentration at which one would need to be under to drop out of an acute category 1 classification would be 2.5%.
4.1.2.1 (B) Chronic aquatic toxicity
EqNOECm = 1.03mg/l When diluted with water to 18.5%, copper sulphate is no longer a chronic category 2. Therefore, the deciding parameter for the purpose of the Seveso III classification is the acute category 1, which under the present state of knowledge, only applies if the concentration is > 7%. In conclusion, under the present state of knowledge, copper sulphate is no longer classified as a dangerous substance for the purpose of the SEVESO III Directive if the concentration is ≤ 7%.

4.2 Potassium Isoamyl Xanthate 90%
4.2.1 Substance Information
Potassium Isoamyl Xanthate 90% (PAX herein) has the following hazard phrase thereby placing it in the E2 classification category under the SEVESO III directive:
- H411 Aquatic chronic category 2
PAX is inherently biodegradable as stated on the SDS supplied by Algol Chemicals, and can further be classified as rapidly degradable according to ECHA.21 The degradation products formed include alcohol, carbon disulphide, hydrogen disulphide and sulphur ions and are dependent on varying factors such as temperature, pH and concentration of the solution.
These products are also classified as rapidly degrading as according to section 4.1.2.9.2 of the CLP regulation, a BOD (5 days)/COD ratio of => 0.5 is considered indicative of rapid degradation. Table 4 (i) displays a summary of the degradability data of the degradation products of Potassium Isoamyl Xanthate.
Table 4 (i): Summary of degradability data of the degradation products of PAX
Substance Name CAS No. BOD (5Days) COD Ratio Rapidly Degradable?
Alcohol (Ethanol) 64-17-5 1.067 g O2/g test material
1.99 g O2/g test material
0.53 Yes
Carbon Disulphide 75-15-0 Not Provided Not Provided Not
Provided
Yes (Stated on ECHA as substance is 100% readily biodegradable)
Hydrogen disulphide and sulphur ions are inorganic compounds therefore the concept of degradability has no bearing.
According to sections 4.1.2.7.1 & 4.1.2.7.2 of the CLP regulation, acute aquatic toxicity should be determined using a fish 96-hour LC50, a Crustacea species 48-hour EC50 and/or an algal species 72/96-hour EC50 whilst for chronic aquatic toxicity NOECs or other equivalent ECx values shall be used.
The following values were obtained the 2013 SDS (included in attachment 1) supplied by Algol Chemicals Oy:
- NOEC Fish (28 days) 0.79 mg/l
- NOEC Crustacea None
- NOEC Algae (72 hours) 1 mg/l
Due to the rapidly degrading nature of PAX, it could be argued that a chronic category 3 classification would be more appropriate in contrast to the category 2 classification stated on the SDS. These calculations will assume the category 2 classification as according to the SDS in the interest of being conservative.
Adequate toxicity data is available two out of the three trophic levels, therefore according to the criteria given in Table 4.1.0(b)(ii) of the CLP regulation, obtaining an NOEC value of >0.1 mg/l would classify the substance as category chronic 3, thereby removing it from the scope of Seveso III.
The most conservative NOEC value of 0.79 mg/l for fish is used for this calculation.

4.3 Sodium Ethyl Xanthate
4.3.1 Substance Information
100% Sodium Ethyl Xanthate (SEX) has the following hazard phrases thereby placing it in the E1 classification category under the SEVESO III directive:
- H400 Aquatic acute category 1
- H410 Aquatic chronic category 1
SEX is inherently biodegradable as stated on SDS supplied by Algol Chemicals and can further be classified as rapidly degradable according to ECHA.3 It decomposes in water giving alcohol, carbon disulphide and hydrogen disulphide as degradation products. Both alcohol and carbon disulphide are rapidly degrading substances as stated in Table ii below.
Hydrogen disulphide is an inorganic compound and as such the concept of degradability has no bearing on it.
According to section 4.1.2.9.2 of the CLP regulation, a BOD (5 days)/COD ratio of ≥ 0.5 is considered indicative of rapid degradation. Table 4 (ii) displays a summary of the degradability data of the degradation products of Sodium Ethyl Xanthate.

According to sections 4.1.2.7.1 & 4.1.2.7.2 of the CLP regulation, acute aquatic toxicity should be determined using a fish 96-hour LC50, a Crustacea species 48-hour EC50 and/or an algal species 72/96-hour EC50 whilst for chronic aquatic toxicity NOECs or other equivalent ECx values shall be used.
The following values were obtained from the SDS supplied by Algol Chemicals Oy:
- LC50 Fish (96hours) 0.12 mg/l
- EC50 Crustacea (24hours) 0.35 mg/l
- EC50 Algae (72hours) 10.51 mg/l
- NOEC Algae (72hours) 1 mg/l
- NOEC Fish (28 days) < 0.03 mg/l
- NOEC Crustacea (21days) 0.047mg/l
Adequate toxicity data is available from all three trophic levels, therefore according to the criteria given in 4.1.0 (a) & (b)(ii) of the CLP regulation for acute and chronic aquatic toxicity, obtaining an LC50 value of > 1mg/l and NOEC value of >0.1 mg/l respectively would classify this substance as category chronic 3, thereby removing it from the scope of Seveso III.

4.3.2 Calculation
4.1.3.5.2 (A) Acute aquatic toxicity
The most conservative LC50 value of 0.12 mg/l for Fish is used for the calculation of acute aquatic toxicity.
4.1.3.5.2 (B) Chronic aquatic toxicity
The most conservative NOEC value of 0.03 mg/l for Fish is used for the calculation of chronic aquatic toxicity.
As can be seen above, the defining parameter for Seveso III classification is the requirement to obtain a classification outside of acute category 1. At this concentration a classification which is no longer chronic category 2 is confirmed. In conclusion, when diluted with water to 11.5%, SEX is no longer classified as a dangerous substance for the purpose of the SEVESO III directive.

4.4 Sodium Iso-Propyl Xanthate
4.4.1 Substance Information
100% Sodium Iso-Propyl Xanthe (SIPX) has the following hazard phrases thereby placing it in the E2 classification category under the SEVESO III directive:
- H411 Aquatic chronic category 2
SIPX is inherently biodegradable, as stated on SDS supplied by Boric Chemicals Ltd. and can further be classified as readily biodegradable in water according to ECHA4. It decomposes in water giving carbon disulphide and Isopropyl Alcohol (propanol) as degradation products. Both carbon disulphide and Isopropyl Alcohol are rapidly degrading substances as stated in table ii below.
Hydrogen disulphide is an inorganic compound and as such the concept of degradability has no bearing on it.
According to section 4.1.2.9.2 of the CLP regulation, a BOD (5 days)/COD ratio of => 0.5 is considered indicative of rapid degradation. Table 4 (iii) displays a summary of the degradability data of the degradation products of Sodium Iso-Propyl Xanthate.

According to the CLP Regulation and ECHA, the harmonised hazard classification for Sodium Iso-Propyl Xanthate in its pure state (100% concentration) is; Aquatic Chronic Category 2 (H411). However, the available toxicology data for this substance in displayed in Table 4 (v) previously does not meet the criteria for classification as Aquatic Chronic Category 2 (H411) listed in Table 4.1.0 of the CLP Regulation. In this instance, one must refer to Table 4.1.2 of the CLP Regulation displayed below;
According to Table 4.1.2 above, a mixture is classified as Chronic 2 when the concentration of classified components is more than or equal to 25%. Therefore, a solution of less than or equal to 25% Sodium Iso-Propyl Xanthate in water will be classified as Chronic Category 3 and will no longer be classified as a dangerous substance for the purpose of the SEVESO III directive.

4.5 Zinc Sulphate Anhydrous, Monohydrate
4.5.1 Substance Information
100% Zinc sulphate has the following hazard phrase thereby placing it in the E1 classification category under the SEVESO III directive:
- H400 Aquatic acute category 1
- H410 Aquatic chronic category 1
Zinc sulphate is an inorganic substance therefore the concept of degradability as applied to organic compounds has no bearing as stated in section 4.1.2.10.1 of the CLP regulation.
4.5.2 Calculation
The information submitted by the Zinc REACH users group for Zinc Sulphate5, provided an ‘M’ number of 1 for both acute aquatic and chronic aquatic hazards. Neither information on the biodegradability / bioaccumulation of zinc sulphate nor chronic eco-toxicity data was available, so these ‘M’ numbers were used for the summation calculation, as per Section 4.1.3.5.5. of the CLP Regulation.
Table 4.1.1: Acute aquatic toxicity
At 25 w/w% concentration zinc sulphate is not acute aquatic toxicity category 1.
Table 4.1.2: Chronic aquatic toxicity
The determining parameter for Seveso classification of zinc sulphate is the chronic aquatic toxicity of 2.5%. In conclusion when diluted with water to 2.5% zinc sulphate is no longer classified as a dangerous substance for the purpose of the SEVESO III directive.

Local exhaust ventilation: Provide local exhaust ventilation in mixing step regarding the exposure to carbon disulphide via inhalation route to ensure that the occupational exposure limit is not exceeded. General ventilation: good general ventilation (3 – 5 air changes per hour) in other process steps is sufficient to keep the exposure via inhalation at acceptable level. Monitoring: Monitor exposure to carbon disulphide around high risk areas such as mixing or cleaning operations.
Individual protection measures: Respiratory protection Wear a suitable mask with filter type A or AX (EN141 or EN405). Use self-
contained breathing apparatus (EN 137) if engineering controls are not fitted or inadequate.
Hand protection Use chemical resistant plastic or rubber gloves (EN374)
Eye/face protection Wear suitable goggles or safety glasses with side shields. Minimum standard
EN166. Skin protection For body protection use apron or other light protective clothing and boots.
Environmental exposure controls: Housekeeping: General good hygiene and housekeeping.
Waste water treatment: Processes should be optimized for effective recycling of process water to minimize the runoff water discharge to surface waters. Any discharge of the substance to sewer needs to be avoided. Treat using the best available techniques before discharge into drains or the aquatic environment. Use tailings dams of appropriate size. Monitor the pH and quality of runoff waters and/or tailings water. Air purification: Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels. Waste: Any residues, including spills and contaminants on the floor, are to be collected as hazardous waste in enclosed sinks/basins or appropriate containers and shall be treated as hazardous waste via licensed waste contractors. Prevent any discharge to the environment.

disulphide, and possibly hydrogen disulphide (H2S) - pH 6: half-life = 1.6 d (25 ˚C) - pH 5.5: half-life = 7 – 14 d (15 ˚C) Neutral: The main degradation products are alcohols and carbon disulphide, carbonate and trithiocarbonate ions. -pH 7: half-life = 11 d (25 ˚C) -pH 7.5: half-life = 47 d (17 ˚C) -pH 7.5: half-life = 58 - 67 d (15 ˚C) Alkaline: The main degradation products are alcohols, carbon disulphide, carbonate and trithiocarbonate ions. - pH 9 = 24 d (25 ˚C) Strong alkaline: The main degradation products are alcohols, carbonate and sulphide (S2-) anions. Hydrogen sulphide may be liberated.
12.3 Bioaccumulative potential Low potential for bioaccumulation (estimated log Kow = -0.76). The substance is hydrolytically unstable, and
laboratory studies on biodegradation also present the substance to be inherently biodegradable. When the substance comes into contact with water or moisture, hydrolysis will take place, carbon disulphide and alcohols (3-methylbutan-1-ol and pentan-1-ol) being the most critical degradation products. These decomposition products have a low bioaccumulation potential (log Kow values < 4).
12.4 Mobility in soil Based on the estimated Koc (24.21), this substance does not have strong adsorption potential to solid particles. Based
on the water solubility it is expected to be mobile in soil but as hydrolytically unstable decomposes in water. 12.5 Results of PBT and vPvB assessment Persistent:
Not persistent or very persistent as the substance is inherently biodegradable. This substance is also hydrolytically unstable with half-life of 47 days under pH 7.5 at 17 deg. C. Based on the knowledge of the degradation reactions and the half-lives at the relevant environmental conditions the most critical degradation products are (1) carbon disulphide and (2) 3-methyl-1-butanol and 1-pentanol. Alcohols are readily biodegradable and possess low toxicity to aquatic organisms. Carbon disulphide is biodegradable in the aqueous environment. Due to its volatility it is expected to evaporate to air, where it degrades having half-life of one week.
Bioaccumulation: Not bioaccumulative or very bioaccumulative as log Kow -0.76 is not above the limit of 4.5 (REACH Annex XIII).
Toxic: Not toxic as the chronic and sub-chronic NOEC values (0.1 to 1 mg/l) are not below the limit of 0.01 mg/l (REACH Annex XIII) and this substance is not classified as mutagenic, reproduction toxic or toxic to target organs after repeated exposure.
The criteria set for classification of the substance to PBT or vPvB is not fulfilled.
12.6 Other adverse effects The substance has no potential for stratospheric ozone depletion for structural reasons. No reason for any hazard
classification under CLP or DSD for atmospheric environment (the ozone layer).

Storage of solution PROC 1
Flotation PROC 2
Froth drying - elevated temperature PROC 22
Froth drying - ambient temperature PROC 26
Description of activities covered in the Exposure Scenario:
Potassium isoamyl xanthate is marketed and handled in pellet form in the EU to avoid formation of dust. The substance is used typically as a 20 % water solution in mining industry as a flotation agent. After discharge and dissolution of pellets into an aqueous solution in the mixing phase, the substance is used in flotation process for the recovery of metal sulphides from ore slurries. The following process steps and activities are covered in the worker exposure scenario; 1) charging, 2) mixing, 3) storage of the water solution, 4) flotation, and 5) froth drying. The use application includes maintenance, cleaning and waste management activities. These are not assessed as a separate process step with a specific PROC but are considered to be included in the assessment with applicable PROCs for other process steps (PROC8b). In addition, sampling is considered to be covered with PROC 8b. Therefore the assessment focuses on PROC8b and PROC3.A quantitative assessment was carried out for systemic long term hazards via inhalation focusing on the potential exposure of workers to CS2 emissions arising because of substance decompose in water. Available monitoring data and calculated estimates with ECETOC TRA v.3 model were both used in the assessment. Environmental exposure scenario focuses on tailings pond to where the effluents containing potassium isoamyl xanthate residues after flotation and drying steps are discharged and treated. Measured data on the effluent concentrations in the tailings ponds and measured concentrations of runoff waters were used for calculations of predicted environmental concentrations (PEC) of the substance in the surface waters (freshwater and marine water). The recommended Tier 1 model (EUSES) was not considered applicable for the exposure assessment of the identified use and the waste water treatment method. Qualitative risk characterization was conducted for the environmental fate and distribution of the decomposition products of potassium isoamyl xanthate formed during the tailings pond treatment.
2. Conditions of use affecting exposure

Other given operational conditions affecting environmental exposure
Discharge rate of tailings pond effluent: (model default value >= 2000 m3/d is not applicable). Discharge to the surrounding surface water is avoided by effective recycling of process waters. Occasional discharge of tailings pond effluents is needed because of seasonal variation in water balance. The discharge rate is dependent on the seasonal variation in the flow rates of receiving surface waters and rainfall. The discharge rate is regulated by controlling the dilution ratio between the effluent discharge flow rate and the surface water flow rate. Information on the discharge rates from industrial downstream users applied in the assessment: Lowest discharge rate (low-water period): ≥ 2592 m3/d (0.03 m3/s) Highest discharge rate (flood period): ≥ 10 368 m3/d (0.12 m3/s)
Receiving surface water flow rate: (model default value >= 18 000 m3/d), not applicable. Based on the environmental permits of the mining companies, the receiving water flow rate should be high enough to enhance proper mixing and dilution of the effluent discharge in receiving surface water. In most of the European countries, the dilution ratio between the flow rates of discharge water compared to the flow rates of receiving surface water is regulated by environmental permits and varies depending on the location of the site. Data on the average flow rates of surface waters from two mine companies applied in the assessment: Receiving water: river Receiving surface water flow rate (minimum flow, low-water period): 432 000 m3/d (5 m3/s) Receiving surface water flow rate (maximum flow, flood period): 1296000 m3/d (15 m3/s) Dilution factors: Calculation A: based on the observed concentrations of the substance in tailings pond: Freshwater: 35 Marine water: 100 Dilution factor in freshwater estimated based on dilution of observed concentrations in tailings pond versus observed concentrations in run-off waters Calculation B:based on observed concentrations in runoff waters: Freshwater: 166 (low-flow) Marine water: 1000 Dilution factor in freshwater are calculated based on discharge and receiving water flow rates (ECHA guidance R16)
Technical conditions and measures at process level (source) to prevent release and technical onsite conditions and measures to reduce or limit discharges, air emissions and releases to soil
Processes optimized for effective recycling of process water to minimize the runoff water discharge to surface waters. Monitoring of pH in the tailings pond and the pH level of runoff waters. Keeping the retention time in the tailings pond long. Use of additional treatment method such as soil infiltration when applicable before runoff waters are discharged to the surrounding environment. Monitoring of waste water quality and monitoring of the environmental impacts of runoff water discharge to the surrounding surface waters. Acting according to the regulations set by the environmental permits.
Housekeeping: General good hygiene and housekeeping. Waste water treatment: Any discharge of the substance to sewer needs to be avoided. Treatment of waste waters using the best available techniques before discharge into drains or the aquatic environment. Use tailings pond of appropriate size. Air purification: Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels. Waste: Any residues, including spills and contaminants on the floor, are to be collected as hazardous waste in enclosed sinks/basins or appropriate containers and shall be treated as hazardous waste via licensed waste contractors. Any discharge to the environment shall be prevented.

Organizational measures to prevent/limit release from site
Environmental, health and safety guidelines or written instructions on the standard operating procedure (SOP) are utilized. Environment, health and safety (EHS) responsibilities are defined and assigned in writing. Emergency action plans (Rescue training for accidental emissions) are created. Personnel are trained in environment, health and safety issues, i.e. in safe handling of chemicals and good housekeeping. Good hygiene measures practiced. It is assumed that a comprehensive PPE program is implemented including selection, fit testing, training in use, maintenance and recording, as appropriate. Exposure should be controlled primarily by avoidance of contact with the substance, for instance by limiting duration of activity, minimization of manual phases and by minimization of staff exposed. General good hygiene and housekeeping. Substance is combustible and might evolve highly flammable, hazardous carbon disulphide vapours. Carbon disulphide is very volatile and poses a fire hazard because of its low auto ignition point and high flammability. The xanthate itself is not classified as self-igniting or flammable in contact with water. Conditions which are conducive to carbon disulphide formation and its flammability such as moisture and heat should be avoided by proper handling and storage of the substance. Because of fire hazard any discharge to sewer shall be avoided. In handling and storage the following practices minimize the risks of fire:
- storage of solid xanthate in a cool, dry place - prohibition of all sources of ignition - good personal hygiene practices

Conditions and measures related to personal protection, hygiene and health evaluation for charging (PROC 8b) and mixing (PROC 3)
Since this substance is classified as skin sensitizer (Skin Sens. 1) and as skin corrosive causing serous eye damage (Skin Corr.1A) the possibility of exposure via dermal route and via eye contact is minimized with operational conditions and with the use of personal protective equipment. Short-term and long-term dermal exposure and exposure via eye contact were considered negligible when appropriate PPEs are in use. Safe use of the substance is ensured if the following personal protection equipment are in use: Respiratory Protection: Yes [Effectiveness Inhalation: 90%] Eye/face protection: goggles or safety glasses with side shields – Chemical resistant Hand protection: Protective gloves – Chemical resistant Body protection: Protective clothing –Chemical resistant Body protection: Boots – Chemical resistant Housekeeping: General good hygiene and housekeeping
3. Exposure estimation and reference to its source
The recommended model (ECETOC TRA v.3) was used to estimate the exposure of workers via inhalation route. In addition, available measured exposure levels were used to support the calculated exposure estimates. Dermal exposure of workers was assessed qualitatively. Environmental exposure assessment was conducted semi-quantitatively because the recommended model (EUSES 2.1) was not applicable for the assessment. As waste water containing the substance residues is discharged and treated in tailings ponds, the treatment differs significantly from the assumptions of the model, in which the exposure to environment concentrates on the sewage treatment in municipal or industrial biological treatment plants. Therefore, a semi-quantitative assessment for the environment was conducted using all available data on the measured concentrations of the substance in tailings pond and runoff waters taken into account the dilution factors (ECHA guidance R16) in freshwater and marine water. The environmental fate and distribution at local and regional scale (tailings ponds) was assessed qualitatively based on the information on potassium isoamyl xanthate and its degradation products. Information on other xanthates used for similar purposes was also used in the assessment.

Date: 17th May 2013 Version 1.0 Previous date: -
Freshwater (sediment) Marine water (sediment)
not applicable not applicable not applicable There is low potential for adverse effects to sediments as potassium isoamyl xanthate is known to degrade by hydrolysis in neutral to slightly alkaline conditions mainly to alcohols, carbonates and dithiocarbonates. In addition, no partition to sediments is assumed based on the low log Kow (-0.76) and Koc (24.21) of the substance, estimated by using EPISUITE (EPA 2013). As a result the overall exposure to sediments is expected to be insignificant based on the low concentrations entering to surface water, the decomposition of the substance, and the partitioning behaviour of the substance.
Air not applicable not applicable not applicable Air emissions from the process steps (charging and mixing) are expected to be low as the process operates in a contained system. The indirect air emissions from waste water treatment are related to the decomposition products as xanthate is hydrolytically unstable and non-volatile. Carbon disulphide (CS2) is the most critical decomposition product which is expected to volatilize to atmosphere. If released to surface water CS2 is expected to move rapidly to the atmosphere (estimated evaporation half-life from a saturated solution 11 min). If released to atmosphere from tailings pond, the half-life of CS2 through reaction with hydroxyl radicals is estimated to be 5.5-15 days and through photolysis, the atmospheric half-life is estimated to be about 11 d. Overall, the emissions of CS2 from tailings pond to air are considered insignificant based on the monitoring data from the tailings area and the mining processes.
STP not applicable not applicable not applicable No connection to municipal waste water treatment plant. Waste waters are treated in tailings pond.
Agricultural soil not applicable not applicable not applicable No direct releases to soil. No indirect releases as no spreading of waste water treatment sludge as fertilizer to soil.

Acute local and systemic effects
Since no high peak exposure is identified in the processes, exposure assessment and risk characterisation is not required. The hazard level is assigned based on the classification of the substance. The assignment rules are described in section E.3.4.4 of part E of the Guidance on Information Requirement and Chemical Safety Assessment. Substance is classified as corrosive to the skin (Skin Corr. 1A; R35) and sensitizer to skin (Skin Sens. 1; R43). According to ECHA Guidance Part E this substance is categorized to the high hazard category. For different hazard levels recommendations for general risk management measures, operational conditions and personal protective equipment are given (ECHA Guidance part E; Table E.3-1). In the uses of this substance the relevant recommendations given to high hazard substance are applied.
Long-term local effects via inhalation route
Workers are protected from the exposure with operational conditions and the use of personal protective equipment (see section 2.2 and 2.3).
Long-term local effects via dermal route and eye
Due to the operational conditions and the use of personal protective equipment local effects by dermal exposure and to eye are not expected (see section 2.2 and 2.3).
4. Guidance to DU to evaluate whether he works inside the boundaries set by the ES
This exposure scenario does not address consumers or professional workers. The exposure assessment and risk characterization for inhalation exposure of workers conducted by using Tier 1 ECETOC TRA v.3 model indicates safe use when the recommended operational conditions and risk management measures are in use (see sections 2.1 and 2.2). Based on the modelling results of industrial use of xanthate in mining industry as flotation agent (ES1), the respiratory protection is required for safe use to prevent exposure via inhalation. Since this substance is classified as skin sensitizer (Skin Sens. 1) and as skin corrosive (Skin Corr.1A) the possibility of exposure via dermal route is minimized with operational conditions and with the use of personal protective equipment. The dermal exposure of workers is controlled to a safe level if the recommended operational conditions and risk management measures are in use (see section 2.1 and 2.2 and section 8.2 of SDS). Environmental exposure scenario is conducted by using the observed concentrations of xanthate either in tailings pond waters or in discharge waters. The scenario indicates safe use when the recommended operational conditions and risk management measures are in use (see section 2.1). Scaling of worker exposure can be done by using ECETOC TRA v.3 model by modifying the concentration (i.e. using observed monitoring data on carbon disulphide emissions if available) and the exposure time of charging or mixing steps. The compliance can also be verified by monitoring of CS2 emissions from the mixing area and during cleaning and maintenance, and by comparing the monitored level with the DNEL value (section 3). Scaling of environmental exposure scenario can be done by comparing the monitoring data on xanthate concentrations in runoff waters with the PNECs (section 3). The use is considered safe if the measured emissions divided by the DNEL or PNEC –values is resulting a risk characterisation ratio (RCR) less than 1.

that the occupational exposure limit is not exceeded. General ventilation: good general ventilation (3 – 5 air changes per hour) in other process steps is sufficient to keep the exposure via inhalation at acceptable level. Monitoring: Monitor exposure to carbon disulphide around high risk areas such as mixing or cleaning operations.
Individual protection measures: Respiratory protection Wear a suitable mask with filter type A or AX (EN141 or EN405). Use self-
contained breathing apparatus (EN 137) if engineering controls are not fitted or inadequate.
Hand protection Use chemical resistant plastic or rubber gloves (EN374)
Eye/face protection Wear suitable goggles or safety glasses with side shields. Minimum standard
EN166. Skin protection For body protection use apron or other light protective clothing and boots.
Environmental exposure controls: Housekeeping: General good hygiene and housekeeping.
Waste water treatment: Processes should be optimized for effective recycling of process water to minimize the runoff water discharge to surface waters. Any discharge of the substance to sewer needs to be avoided. Treat using the best available techniques before discharge into drains or the aquatic environment. Use tailings dams of appropriate size. Monitor the pH and quality of runoff waters and/or tailings water. Air purification: Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels. Waste: Any residues, including spills and contaminants on the floor, are to be collected as hazardous waste in enclosed sinks/basins or appropriate containers and shall be treated as hazardous waste via licensed waste contractors. Prevent any discharge to the environment.

SECTION 11. TOXICOLOGICAL INFORMATION
11.1 Information on toxicological effects Basic toxicokinetics: There is no experimental data available on toxicokinetics and the assessment
has been made qualitatively on the basis of the physical and chemical properties and the available information from the most hazardous degradation product, carbon disulphide.
Absorption: Carbon disulphide readily absorbed via inhalation and dermal routes. Distribution: Widely throughout the body. Metabolism: Carbon disulphide (CS2) is mainly metabolized (70-90 %), 1 % excreted
unchanged and remainder exhaled. The metabolic products of CS2 are sulphur compounds and CO2, which are excreted in urine and exhaled.
Acute toxicity: Oral LD50: 730 mg/kg bw (mouse) Dermal LD50: < 1 000 mg/kg bw (rat, 18 h exposure) Inhalation: No valid data are available on acute inhalation toxicity.
Not relevant information as the product is marketed and used in pellet form.
Irritation and corrosion: The substance is corrosive to skin, since the pH of 25 % water solution is 12.2. Thus, the risk of severe eye damage is considered implicit.
Sensitisation: May cause an allergic skin reaction (LLNA mice, analogue substance (potassium isopentyl dithiocarbonate), OECD 429).

Neutral: The main degradation products are alcohol and carbon disulphide, carbonate and trithiocarbonate ions. -pH 7: half-life = 11 d (25 ˚C) -pH 7.5: half-life = 47 d (17 ˚C) -pH 7.5: half-life = 58 - 67 d (15 ˚C) Alkaline: The main degradation products are alcohol, carbon disulphide, carbonate and trithiocarbonate ions. - pH 9 = 24 d (25 ˚C) Strong alkaline: The main degradation products are alcohol, carbonate and sulphide (S2-) anions. Hydrogen sulphide may be liberated.
12.3 Bioaccumulative potential Low potential for bioaccumulation (estimated log Kow = -2.48). The substance is hydrolytically unstable, and
laboratory studies on biodegradation also present the substance to be inherently biodegradable. When the substance comes into contact with water or moisture, hydrolysis will take place, carbon disulphide and ethanol being the most critical degradation products. These decomposition products have a low bioaccumulation potential (log Kow values < 4).
12.4 Mobility in soil Based on the estimated Koc (4.00), this substance does not have strong adsorption potential to solid particles. Based
on the water solubility it is expected to be mobile in soil but as hydrolytically unstable decomposes in water. 12.5 Results of PBT and vPvB assessment Persistent:
Not persistent or very persistent as the substance is inherently biodegradable. This substance is also hydrolytically unstable with half-life of 47 days under pH 7.5 at 17 deg. C. Based on the knowledge of the degradation reactions and the half-lives at the relevant environmental conditions the most critical degradation products are (1) carbon disulphide and (2) ethanol. Alcohol is readily biodegradable and possesses low toxicity to aquatic organisms. Carbon disulphide is biodegradable in the aqueous environment. Due to its volatility it is expected to evaporate to air, where it degrades having half-life of one week.
Bioaccumulation: Not bioaccumulative or very bioaccumulative as log Kow -2.48 is not above the limit of 4.5 (REACH Annex XIII).
Toxic: Not toxic as the chronic and sub-chronic NOEC values (0.1 to 1 mg/l) are not below the limit of 0.01 mg/l (REACH Annex XIII) and this substance is not classified as mutagenic, reproduction toxic or toxic to target organs after repeated exposure.
The criteria set for classification of the substance to PBT or vPvB is not fulfilled.
12.6 Other adverse effects The substance has no potential for stratospheric ozone depletion for structural reasons. No reason for any hazard
classification under CLP or DSD for atmospheric environment (the ozone layer).

Description of activities covered in the Exposure Scenario:
Sodium ethyl xanthate is marketed and handled in pellet form in the EU to avoid formation of dust. The substance is used typically as a 20 % water solution in mining industry as a flotation agent. After discharge and dissolution of pellets into an aqueous solution in the mixing phase, the substance is used in flotation process for the recovery of metal sulphides from ore slurries. The following process steps and activities are covered in the worker exposure scenario; 1) charging, 2) mixing, 3) storage of the water solution, 4) flotation, and 5) froth drying. The use application includes maintenance, cleaning and waste management activities. These are not assessed as a separate process step with a specific PROC but are considered to be included in the assessment with applicable PROCs for other process steps (PROC8b). In addition, sampling is considered to be covered with PROC 8b. Therefore the assessment focuses on PROC8b and PROC3.A quantitative assessment was carried out for systemic long term hazards via inhalation focusing on the potential exposure of workers to CS2 emissions arising because of substance decompose in water. Available monitoring data and calculated estimates with ECETOC TRA v.3 model were both used in the assessment. Environmental exposure scenario focuses on tailings pond to where the effluents containing sodium ethyl xanthate residues after flotation and drying steps are discharged and treated. Measured data on the effluent concentrations in the tailings ponds and measured concentrations of runoff waters were used for calculations of predicted environmental concentrations (PEC) of the substance in the surface waters (freshwater and marine water). The recommended Tier 1 model (EUSES) was not considered applicable for the exposure assessment of the identified use and the waste water treatment method. Qualitative risk characterization was conducted for the environmental fate and distribution of the decomposition products of sodium ethyl xanthate formed during the tailings pond treatment.

Other given operational conditions affecting environmental exposure
Discharge rate of tailings pond effluent: (model default value >= 2000 m3/d is not applicable). Discharge to the surrounding surface water is avoided by effective recycling of process waters. Occasional discharge of tailings pond effluents is needed because of seasonal variation in water balance. The discharge rate is dependent on the seasonal variation in the flow rates of receiving surface waters and rainfall. The discharge rate is regulated by controlling the dilution ratio between the effluent discharge flow rate and the surface water flow rate. Information on the discharge rates from industrial downstream users applied in the assessment: Lowest discharge rate (low-water period): ≥ 2592 m3/d (0.03 m3/s) Highest discharge rate (flood period): ≥ 10 368 m3/d (0.12 m3/s)
Receiving surface water flow rate: (model default value >= 18 000 m3/d), not applicable. Based on the environmental permits of the mining companies, the receiving water flow rate should be high enough to enhance proper mixing and dilution of the effluent discharge in receiving surface water. In most of the European countries, the dilution ratio between the flow rates of discharge water compared to the flow rates of receiving surface water is regulated by environmental permits and varies depending on the location of the site. Data on the average flow rates of surface waters from two mine companies applied in the assessment: Receiving water: river Receiving surface water flow rate (minimum flow, low-water period): 432 000 m3/d (5 m3/s) Receiving surface water flow rate (maximum flow, flood period): 1296000 m3/d (15 m3/s) Dilution factors: Calculation A: based on the observed concentrations of the substance in tailings pond: Freshwater: 35 Marine water: 100 Dilution factor in freshwater estimated based on dilution of observed concentrations in tailings pond versus observed concentrations in run-off waters Calculation B:based on observed concentrations in runoff waters: Freshwater: 166 (low-flow) Marine water: 1000 Dilution factor in freshwater are calculated based on discharge and receiving water flow rates (ECHA guidance R16)
Technical conditions and measures at process level (source) to prevent release and technical onsite conditions and measures to reduce or limit discharges, air emissions and releases to soil
Processes optimized for effective recycling of process water to minimize the runoff water discharge to surface waters. Monitoring of pH in the tailings pond and the pH level of runoff waters. Keeping the retention time in the tailings pond long. Use of additional treatment method such as soil infiltration when applicable before runoff waters are discharged to the surrounding environment. Monitoring of waste water quality and monitoring of the environmental impacts of runoff water discharge to the surrounding surface waters. Acting according to the regulations set by the environmental permits.
Housekeeping: General good hygiene and housekeeping. Waste water treatment: Any discharge of the substance to sewer needs to be avoided. Treatment of waste waters using the best available techniques before discharge into drains or the aquatic environment. Use tailings pond of appropriate size. Air purification: Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels. Waste: Any residues, including spills and contaminants on the floor, are to be collected as hazardous waste in enclosed sinks/basins or appropriate containers and shall be treated as hazardous waste via licensed waste contractors. Any discharge to the environment shall be prevented.

Organizational measures to prevent/limit release from site
Environmental, health and safety guidelines or written instructions on the standard operating procedure (SOP) are utilized. Environment, health and safety (EHS) responsibilities are defined and assigned in writing. Emergency action plans (Rescue training for accidental emissions) are created. Personnel are trained in environment, health and safety issues, i.e. in safe handling of chemicals and good housekeeping. Good hygiene measures practiced. It is assumed that a comprehensive PPE program is implemented including selection, fit testing, training in use, maintenance and recording, as appropriate. Exposure should be controlled primarily by avoidance of contact with the substance, for instance by limiting duration of activity, minimization of manual phases and by minimization of staff exposed. General good hygiene and housekeeping. Substance is combustible and might evolve highly flammable, hazardous carbon disulphide vapours. Carbon disulphide is very volatile and poses a fire hazard because of its low auto ignition point and high flammability. The xanthate itself is not classified as self-igniting or flammable in contact with water. Conditions which are conducive to carbon disulphide formation and its flammability such as moisture and heat should be avoided by proper handling and storage of the substance. Because of fire hazard any discharge to sewer shall be avoided. In handling and storage the following practices minimize the risks of fire:
- storage of solid xanthate in a cool, dry place - prohibition of all sources of ignition - good personal hygiene practices
Conditions and measures related to municipal sewage treatment plant
Municipal STP or onsite biological treatment plant: No [Effectiveness Water: 0%]. Waste water is treated in tailings ponds. Any discharge to sewer shall be avoided.

Since this substance is classified as skin sensitizer (Skin Sens. 1) and as skin corrosive causing serous eye damage (Skin Corr.1A) the possibility of exposure via dermal route and via eye contact is minimized with operational conditions and with the use of personal protective equipment. Short-term and long-term dermal exposure and exposure via eye contact were considered negligible when appropriate PPEs are in use. Safe use of the substance is ensured if the following personal protection equipment are in use: Respiratory Protection: Yes [Effectiveness Inhalation: 90%] Eye/face protection: goggles or safety glasses with side shields – Chemical resistant Hand protection: Protective gloves – Chemical resistant Body protection: Protective clothing –Chemical resistant Body protection: Boots – Chemical resistant Housekeeping: General good hygiene and housekeeping
3. Exposure estimation and reference to its source
The recommended model (ECETOC TRA v.3) was used to estimate the exposure of workers via inhalation route. In addition, available measured exposure levels were used to support the calculated exposure estimates. Dermal exposure of workers was assessed qualitatively. Environmental exposure assessment was conducted semi-quantitatively because the recommended model (EUSES 2.1) was not applicable for the assessment. As waste water containing the substance residues is discharged and treated in tailings ponds, the treatment differs significantly from the assumptions of the model, in which the exposure to environment concentrates on the sewage treatment in municipal or industrial biological treatment plants. Therefore, a semi-quantitative assessment for the environment was conducted using all available data on the measured concentrations of the substance in tailings pond and runoff waters taken into account the dilution factors (ECHA guidance R16) in freshwater and marine water. The environmental fate and distribution at local and regional scale (tailings ponds) was assessed qualitatively based on the information on sodium ethyl xanthate and its degradation products. Information on other xanthates used for similar purposes was also used in the assessment.

Freshwater (sediment) Marine water (sediment)
not applicable not applicable not applicable There is low potential for adverse effects to sediments as sodium ethyl xanthate is known to degrade by hydrolysis in neutral to slightly alkaline conditions mainly to ethanol, carbonates and dithiocarbonates. In addition, no partition to sediments is assumed based on the low log Kow (-2.48) and Koc (4.00) of the substance, estimated by using EPISUITE (EPA 2013). As a result the overall exposure to sediments is expected to be insignificant based on the low concentrations entering to surface water, the decomposition of the substance, and the partitioning behaviour of the substance.
Air not applicable not applicable not applicable Air emissions from the process steps (charging and mixing) are expected to be low as the process operates in a contained system. The indirect air emissions from waste water treatment are related to the decomposition products as xanthate is hydrolytically unstable and non-volatile. Carbon disulphide (CS2) is the most critical decomposition product which is expected to volatilize to atmosphere. If released to surface water CS2 is expected to move rapidly to the atmosphere (estimated evaporation half-life from a saturated solution 11 min). If released to atmosphere from tailings pond, the half-life of CS2 through reaction with hydroxyl radicals is estimated to be 5.5-15 days and through photolysis, the atmospheric half-life is estimated to be about 11 d. Overall, the emissions of CS2 from tailings pond to air are considered insignificant based on the monitoring data from the tailings area and the mining processes.
STP not applicable not applicable not applicable No connection to municipal waste water treatment plant. Waste waters are treated in tailings pond.
Agricultural soil not applicable not applicable not applicable No direct releases to soil. No indirect releases as no spreading of waste water treatment sludge as fertilizer to soil.

Acute local and systemic effects
Since no high peak exposure is identified in the processes, exposure assessment and risk characterisation is not required. The hazard level is assigned based on the classification of the substance. The assignment rules are described in section E.3.4.4 of part E of the Guidance on Information Requirement and Chemical Safety Assessment. Substance is classified as corrosive to the skin (Skin Corr. 1A; R35) and sensitizer to skin (Skin Sens. 1; R43). According to ECHA Guidance Part E this substance is categorized to the high hazard category. For different hazard levels recommendations for general risk management measures, operational conditions and personal protective equipment are given (ECHA Guidance part E; Table E.3-1). In the uses of this substance the relevant recommendations given to high hazard substance are applied.
Long-term local effects via inhalation route
Workers are protected from the exposure with operational conditions and the use of personal protective equipment (see section 2.2 and 2.3).
Long-term local effects via dermal route and eye
Due to the operational conditions and the use of personal protective equipment local effects by dermal exposure and to eye are not expected (see section 2.2 and 2.3).
4. Guidance to DU to evaluate whether he works inside the boundaries set by the ES
This exposure scenario does not address consumers or professional workers. The exposure assessment and risk characterization for inhalation exposure of workers conducted by using Tier 1 ECETOC TRA v.3 model indicates safe use when the recommended operational conditions and risk management measures are in use (see sections 2.1 and 2.2). Based on the modelling results of industrial use of xanthate in mining industry as flotation agent (ES1), the respiratory protection is required for safe use to prevent exposure via inhalation. Since this substance is classified as skin sensitizer (Skin Sens. 1) and as skin corrosive (Skin Corr.1A) the possibility of exposure via dermal route is minimized with operational conditions and with the use of personal protective equipment. The dermal exposure of workers is controlled to a safe level if the recommended operational conditions and risk management measures are in use (see section 2.1 and 2.2 and section 8.2 of SDS). Environmental exposure scenario is conducted by using the observed concentrations of xanthate either in tailings pond waters or in discharge waters. The scenario indicates safe use when the recommended operational conditions and risk management measures are in use (see section 2.1). Scaling of worker exposure can be done by using ECETOC TRA v.3 model by modifying the concentration (i.e. using observed monitoring data on carbon disulphide emissions if available) and the exposure time of charging or mixing steps. The compliance can also be verified by monitoring of CS2 emissions from the mixing area and during cleaning and maintenance, and by comparing the monitored level with the DNEL value (section 3). Scaling of environmental exposure scenario can be done by comparing the monitoring data on xanthate concentrations in runoff waters with the PNECs (section 3). The use is considered safe if the measured emissions divided by the DNEL or PNEC –values result a risk characterisation ratio (RCR) less than 1.

4. Guidance to Downstream User to evaluate whether he works inside the boundaries set by the Exposure Scenario
If conditions differ from those listed in Section 2, downstream user (DU) should check whether they are still within the boundaries of the ES (i.e.,RCR < 1) The following equation may be used for scaling:
Where: RCR ES is the risk characterisation ratio (unitless) M ES is the quantity of substance processed or used per year per site (tonnes/year) Tem,ES is the duration of emission (days/year)

fem,ES is the fraction of substance emitted from the process or use to air, water or soil (unitless) M Actual, Tem,Actual and fem,Actual are the corresponding actual parameters as known to the DU, and RCR Actual is the resulting scaled risk characterisation ratio. Instead of fem,ES, the actual release rates of substance emitted may be used and the following values were used in the assessment: Release rate to air (kg/day): 0.1643 (CN-) Release rate to wastewater (kg/day): 0.0065 (CN-) Release rate to soil (kg/day): 0.0 Note: While scaling on conditions and RMMs related to the primary risk driving environmental compartment, be cautious not to exceed limitations set through the next limiting compartment (compare RCRs) Scaling information for worker assessments based on ECETOC TRA: RCRs = RCRo * CFs / CFo can be used for multiple determinants in series e.g. CF1, CF2, CF3 Where: RCRo = original exposure prediction RCRs = scaled exposure prediction CFo = original correction factor CFs = correction factor for scaling
Scaling for LEV: LEV efficiency in professional settings: PROC 24 = 75%; PROC 8b - volatiles; PROC 17, PROC 18 = 80%, all other PROCs = 80% LEV efficiency in industrial settings: PROC 12 - volatiles, PROC 24 - solids = 80%; PROC 8b - volatiles = 97%; PROC 7, PROC 8b - solids, PROC 17, PROC 18 = 95%, all other PROCs = 90% If the downstream user reduces the exposure duration for each activity/process to less than 8 hours, it may be necessary to consider summing exposure estimates if the same worker may be engaged in multiple tasks during the day

Where: RCR ES is the risk characterisation ratio (unitless) M ES is the quantity of substance processed or used per year per site (tonnes/year) Tem,ES is the duration of emission (days/year) fem,ES is the fraction of substance emitted from the process or use to air, water or soil (unitless) M Actual, Tem,Actual and fem,Actual are the corresponding actual parameters as known to the DU, and RCR Actual is the resulting scaled risk characterisation ratio. Instead of fem,ES, the actual release rates of substance emitted may be used and the following values were used in the assessment: Release rate to air (kg/day): 0.434 (CN-) Release rate to wastewater (kg/day): 0.00742 (CN-) Release rate to soil (kg/day): 0.0

Note: While scaling on conditions and RMMs related to the primary risk driving environmental compartment, be cautious not to exceed limitations set through the next limiting compartment (compare RCRs) Scaling information for worker assessments based on ECETOC TRA: RCRs = RCRo * CFs / CFo can be used for multiple determinants in series e.g. CF1, CF2, CF3 Where: RCRo = original exposure prediction RCRs = scaled exposure prediction CFo = original correction factor CFs = correction factor for scaling
Scaling for LEV: LEV efficiency in professional settings: PROC 24 = 75%; PROC 8b - volatiles; PROC 17, PROC 18 = 80%, all other PROCs = 80% LEV efficiency in industrial settings: PROC 12 - volatiles, PROC 24 - solids = 80%; PROC 8b - volatiles = 97%; PROC 7, PROC 8b - solids, PROC 17, PROC 18 = 95%, all other PROCs = 90% If the downstream user reduces the exposure duration for each activity/process to less than 8 hours, it may be necessary to consider summing exposure estimates if the same worker may be engaged in multiple tasks during the day

The following equation may be used for scaling:
Where: RCR ES is the risk characterisation ratio (unitless) M ES is the quantity of substance processed or used per year per site (tonnes/year) Tem,ES is the duration of emission (days/year) fem,ES is the fraction of substance emitted from the process or use to air, water or soil (unitless) M Actual, Tem,Actual and fem,Actual are the corresponding actual parameters as known to the DU, and RCR Actual is the resulting scaled risk characterisation ratio. Instead of fem,ES, the actual release rates of substance emitted may be used and the following values were used in the assessment: Release rate to air (kg/day): 1.944 (CN-) Release rate to soil (kg/day): 0.109 Note: While scaling on conditions and RMMs related to the primary risk driving environmental compartment, be cautious not to exceed limitations set through the next limiting compartment (compare RCRs) Scaling information for worker assessments based on ECETOC TRA: RCRs = RCRo * CFs / CFo can be used for multiple determinants in series e.g. CF1, CF2, CF3 Where: RCRo = original exposure prediction RCRs = scaled exposure prediction CFo = original correction factor CFs = correction factor for scaling
Scaling for LEV: LEV efficiency in professional settings: PROC 24 = 75%; PROC 8b - volatiles; PROC 17, PROC 18 = 80%, all other PROCs = 80% LEV efficiency in industrial settings: PROC 12 - volatiles, PROC 24 - solids = 80%; PROC 8b - volatiles = 97%; PROC 7, PROC 8b - solids, PROC 17, PROC 18 = 95%, all other PROCs = 90%

4. Guidance to Downstream User to evaluate whether he works inside the boundaries set by the Exposure Scenario
If conditions differ from those listed in Section 2, downstream user (DU) should check whether they are still within the boundaries of the ES (i.e.,RCR < 1) The following equation may be used for scaling:
Where: RCR ES is the risk characterisation ratio (unitless) M ES is the quantity of substance processed or used per year per site (tonnes/year) Tem,ES is the duration of emission (days/year) fem,ES is the fraction of substance emitted from the process or use to air, water or soil (unitless) M Actual, Tem,Actual and fem,Actual are the corresponding actual parameters as known to the DU, and RCR Actual is the resulting scaled risk characterisation ratio. Instead of fem,ES, the actual release rates of substance emitted may be used and the following values were used in the assessment: Release rate to air (kg/day): 0.09 (CN-) Release rate to wastewater (kg/day): 0.0043 (CN-) Release rate to soil (kg/day): 0.0 Note: While scaling on conditions and RMMs related to the primary risk driving environmental compartment, be cautious not to exceed limitations set through the next limiting compartment (compare RCRs) Scaling information for worker assessments based on ECETOC TRA: RCRs = RCRo * CFs / CFo can be used for multiple determinants in series e.g. CF1, CF2, CF3 Where: RCRo = original exposure prediction RCRs = scaled exposure prediction CFo = original correction factor CFs = correction factor for scaling

4. Guidance to Downstream User to evaluate whether he works inside the boundaries set by the Exposure Scenario
If conditions differ from those listed in Section 2, downstream user (DU) should check whether they are still within the boundaries of the ES (i.e.,RCR < 1) The following equation may be used for scaling:
Where: RCR ES is the risk characterisation ratio (unitless) M ES is the quantity of substance processed or used per year per site (tonnes/year) Tem,ES is the duration of emission (days/year) fem,ES is the fraction of substance emitted from the process or use to air, water or soil (unitless) M Actual, Tem,Actual and fem,Actual are the corresponding actual parameters as known to the DU, and RCR Actual is the resulting scaled risk characterisation ratio. Instead of fem,ES, the actual release rates of substance emitted may be used and the following values were used in the assessment: Release rate to air (kg/day): 0.00116 (CN-) Release rate to wastewater (kg/day): 0.0005724 (CN-) Release rate to soil (kg/day): 0.00 Note: While scaling on conditions and RMMs related to the primary risk driving environmental compartment, be cautious not to exceed limitations set through the next limiting compartment (compare RCRs) Scaling information for worker assessments based on ECETOC TRA: RCRs = RCRo * CFs / CFo can be used for multiple determinants in series e.g. CF1, CF2, CF3 Where: RCRo = original exposure prediction RCRs = scaled exposure prediction CFo = original correction factor

CFs = correction factor for scaling
Scaling for LEV: LEV efficiency in professional settings: PROC 24 = 75%; PROC 8b - volatiles; PROC 17, PROC 18 = 80%, all other PROCs = 80% LEV efficiency in industrial settings: PROC 12 - volatiles, PROC 24 - solids = 80%; PROC 8b - volatiles = 97%; PROC 7, PROC 8b - solids, PROC 17, PROC 18 = 95%, all other PROCs = 90% If the downstream user reduces the exposure duration for each activity/process to less than 8 hours, it may be necessary to consider summing exposure estimates if the same worker may be engaged in multiple tasks during the day
