            COMMISSION IMPLEMENTING REGULATION (EU) 2025/1906
of 12 September 2025
         
granting a Union authorisation for the biocidal product family ‘GA 24-50 BPF’ in accordance with Regulation (EU) No 528/2012 of the European Parliament and of the Council
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) No 528/2012 of the European Parliament and of the Council of 22 May 2012 concerning the making available on the market and use of biocidal products (1), and in particular Article 44(5), first subparagraph, thereof,

Whereas:







(1)


On 20 September 2016, MC (Netherlands) 1 B.V. submitted an application to the European Chemicals Agency (‘the Agency’) in accordance with Article 43(1) of Regulation (EU) No 528/2012 for Union authorisation of a biocidal product family named ‘GA 24-50 BPF’ of product-types 6, 11 and 12, as described in Annex V to that Regulation, providing written confirmation that the competent authority of the Netherlands had agreed to evaluate the application. The application was recorded under case number BC-AE027041-75 in the Register for Biocidal Products.












(2)


‘GA 24-50 BPF’ contains glutaraldehyde as the active substance, included in the Union list of approved active substances referred to in Article 9(2) of Regulation (EU) No 528/2012 for product-types 6, 11 and 12.












(3)


On 31 May 2022, the evaluating competent authority submitted, in accordance with Article 44(1) of Regulation (EU) No 528/2012, an assessment report and the conclusions of its evaluation to the Agency.












(4)


On 18 March 2025, the Agency submitted to the Commission its opinion (2), the draft summary of the biocidal product characteristics (‘SPC’) of ‘GA 24-50 BPF’ and the final assessment report on the biocidal product family, in accordance with Article 44(3) of Regulation (EU) No 528/2012.












(5)


The opinion concludes that ‘GA 24-50 BPF’ is a biocidal product family within the meaning of Article 3(1), point (s), of Regulation (EU) No 528/2012, that it is eligible for Union authorisation in accordance with Article 42(1) of that Regulation and that, subject to compliance with the draft SPC, it meets the conditions laid down in Article 19(6) of that Regulation.












(6)


The active substance glutaraldehyde meets the criteria for classification as a substance that can lead to respiratory sensitisation as defined in Section 3.4.1.1 of Annex I to Regulation (EC) No 1272/2008 of the European Parliament and of the Council (3). Therefore, that active substance meets the conditions for being considered a candidate for substitution in accordance with Article 10(1), point (b), of Regulation (EU) No 528/2012 and the evaluating competent authority performed a comparative assessment of the biocidal product family in accordance with Article 23(1) of that Regulation. In the comparative assessment no alternative could be identified as the chemical diversity was considered insufficient to substitute ‘GA 24-50 BPF’. Therefore, the biocidal product family should be authorised for a period not exceeding 5 years in accordance with Article 23(6) of Regulation (EU) No 528/2012.












(7)


On 11 April 2025, the Agency transmitted to the Commission the draft SPC in all the official languages of the Union in accordance with Article 44(4) of Regulation (EU) No 528/2012.












(8)


The Commission concurs with the opinion of the Agency and considers it therefore appropriate to grant a Union authorisation for the biocidal product family ‘GA 24-50 BPF’.












(9)


The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Biocidal Products,





HAS ADOPTED THIS REGULATION:



Article 1

4.5.1.   Use-specific instructions for use

Crude tanks being treated should be at least 10% full before treatment. Do not dispense into empty crude tanks. When treating storage tanks, please note that effective treatment will only be achieved with efficient mixing. Ideally, the biocidal product should be dosed into a flowing crude oil stream in the storage tank inlet.
Dose 0,025 to 0,4 g glutaraldehyde per liter of water content in crude oil.
Dose level should be proportional to the risk and level of infection, and anticipated time before the next treatment or fluid discharge. Dosing system should be a closed system. Adequate agitation is required to ensure homogeneity throughout the fluid volume.
The dose and frequency strongly depend on the formulation and intended use of the matrix (crude oil) to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.5.2.   Use-specific risk mitigation measures

See general directions for use. Additionally:
In case of direct release of the aqueous phase to the sewer the concentration shall not exceed 0,75 mg glutaraldehyde/L.

4.10.1.   Use-specific instructions for use

Glutaraldehyde should be dosed separately from other oil field chemistries such as antifoaming agents, oxygen scavengers, flocculants, or other oxidizing biocides (e.g. chlorite) in order to prevent cross reactivity. Successive addition may therefore be required to optimize performance. If a deaerator is being treated with oxidizing biocides, glutaraldehyde should be dosed downstream of the deaeration unit.
Dose 50 to 1 000 g glutaraldehyde per m3 of injection water.
The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.10.2.   Use-specific risk mitigation measures

If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the produced water. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Produced water containing up to 750 mg/L glutaraldehyde can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.
When applied onshore, preserved fluids must be recycled or disposed of as hazardous waste. If release to the sewer is unavoidable, the concentration shall not exceed 1 mg glutaraldehyde/L.

Preservation of water-based fracturing fluids for the oil and gas industry (i.e. shale gas extraction, wet shale extraction, shale oil extraction, production from tight gas reservoirs, production of coal bed methane and fracturing in conventional reservoirs).




Application method(s)


Method: closed system
Detailed description:
Glutaraldehyde is typically applied in a mixing tank, as it cannot be exposed to open systems such as the hydraulic fracturing pond or other open water sources that make up the hydraulic fracturing pond water. Glutaraldehyde is applied to the mixing tank using automated pumps, together with other chemicals such as but not limited to friction reducers, gelling agents, proppants (sand in case of slick water), corrosion inhibitors.




Application rate(s) and frequency


Application Rate:
Bacteria: curative use, 50 to 1 000  g glutaraldehyde per m3 of fracturing fluid with a contact time of 24 hours. Anaerobic bacteria: preventive use, 150 to 1 000  g glutaraldehyde per m3 of fracturing fluid.
Number and timing of application:
In the hydraulic fracturing industry the application of the biocidal product is typically a single injection, which happens during the actual fracturing. A new biocide addition is only done when the well is re-fractured. Refracturing is rare but can be performed up to 20 times during the lifetime of a well. The lifetime of a well can reach up to 20 years.

4.12.1.   Use-specific instructions for use

Typically applied through a closed system to a mixing tank using a pump. Glutaraldehyde may be used in combination with other chemistries such as friction reducers, gelling agents, proppants, and corrosion inhibitors, and applied together with these chemistries in the mixing tank(s). If used for intermittent treatments during operations, a stream of glutaraldehyde will be directly dosed into the process water stream from a separate tank into a closed system, thereby significantly reducing the chance of exposure.
Dose 50 to 1 000 g glutaraldehyde per m3 of fracturing fluid.
The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.12.2.   Use-specific risk mitigation measures

Preserved fracturing fluids are reused where applicable. If discharged into seawater 0,2 mg glutaraldehyde/L fracturing fluid must not be exceeded. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Run lab test to determine the soiling dependent dosage and degradation rate in use.

4.12.3.   Where specific to the use, the particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

See general directions for use.
In addition:
Conditions preventing emissions to water:
Emissions to surface water are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be drained to a lined storage area, preventing release to surface water. Sub-surface releases of fluid during the fracturing process are prevented from reaching aquifers through the presence of relatively impermeable formations above the target formation. This limits upward migration of fluid. This is also relevant for recovered fluids that are re-injected for use or disposal. A minimum vertical separation distance between the target formation and aquifer should be respected. National legislation may also require a minimum depth.
Recovered water may finally be discharged via one or more large-scale waste water treatment plants where a combination of physical and biological treatments will reduce emissions to the receiving water.
Conditions preventing emissions to soil:
Emissions, through downward migration are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be prevented from downward migration to soil by the employment of a non-permeable membrane below the well pad. Sludge from treatment works should not be spread on land.
Existence of standard municipal sewage treatment plant
Waste contractors employed to dispose of recovered water, may do so via a waste water treatment plant, depending on the properties of the water and conditions of local regulations.

4.16.1.   Use-specific instructions for use

Injection water is often deaerated before being pumped into the sub-surface. Separation of chemical treatments should be considered when dosing glutaraldehyde, as it may interfere with other common chemistries such as anti-foams, oxygen scavengers, flocculants, and other oxidizing biocides (e.g. chlorite). Successive addition of different chemical packages may be necessary to prevent cross reactivity and to optimize performance. When a deaerator is present and treated with chlorite or a similar oxidizing chemistry, glutaraldehyde is typically dosed after the deaerator.
Dose 50 to 1 000 g glutaraldehyde per m3 injection water.
The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.16.2.   Use-specific risk mitigation measures

If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the produced water. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Produced water containing up to 750 mg/L glutaraldehyde can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.

4.18.1.   Use-specific instructions for use

Glutaraldehyde is typically applied through a closed system to a mixing tank using a pump Glutaraldehyde may be used in combination with other chemistries such as friction reducers, gelling agents, proppants, and corrosion inhibitors, and applied together with these chemistries in the mixing tank(s). If used for intermittent treatments during operations, a stream of glutaraldehyde will be directly dosed into the process water stream from a separate tank into a closed system, thereby significantly reducing the chance of exposure.
Dose 50 to 1 000 g glutaraldehyde per m3 fracturing fluid, in the hydraulic fracturing water matrix.
The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.18.2.   Use-specific risk mitigation measures

Preserved fracturing fluids are reused where applicable. If discharged into seawater 0,2 mg glutaraldehyde/L fracturing fluid must not be exceeded. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids.

4.18.3.   Where specific to the use, the particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

See general directions for use.
In addition:
Conditions preventing emissions to water:
Emissions to surface water are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be drained to a lined storage area, preventing release to surface water. Sub-surface releases of fluid during the fracturing process are prevented from reaching aquifers through the presence of relatively
impermeable formations above the target formation. This limits upward migration of fluid. This is also relevant for recovered fluids that are re-injected for use or disposal. A minimum vertical separation distance between the target formation and aquifer should be respected. National legislation may also require a minimum depth
Recovered water may finally be discharged via one or more large-scale waste water treatment plants where a combination of physical and biological treatments will reduce emissions to the receiving water.
Conditions preventing emissions to soil:
Emissions, through downward migration are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be prevented from downward migration to soil by the employment of a non-permeable membrane below the well pad. Sludge from treatment works should not be spread on land.
Existence of standard municipal sewage treatment plant
Waste contractors employed to dispose of recovered water, may do so via a waste water treatment plant, depending on the properties of the water and conditions of local regulations.

5.3.   Particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

IF INHALED: Move to fresh air and keep at rest in a position comfortable for breathing.
If symptoms: Immediately call 112/ambulance for medical assistance.
IF SWALLOWED: If conscious, immediately rinse mouth. Give something to drink, if exposed person is able to swallow. Do NOT induce vomiting. Call 112/ambulance for medical assistance.
IF ON SKIN: Immediately wash skin with plenty of water. Thereafter take off all contaminated clothing and wash it before reuse. Continue to wash the skin with water for 15 minutes. Call a POISON CENTRE or a doctor. If skin irritation or rash occur: Get medical advice.
IF IN EYES: Immediately rinse with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing for at least 15 minutes. Call 112/ambulance for medical assistance.
Information to Healthcare personnel/doctor:
Immediately initiate life support measures, thereafter call a POISON CENTRE.

Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. Spills or discharge to natural waterways is likely to kill aquatic organisms.

Personal precautions, protective equipment and emergency procedures in case of accidental release measures: Evacuate area. Keep upwind of spill. Ventilate area of leak or spill. Only trained and properly protected personnel must be involved in clean-up operations. Use appropriate safety equipment.

Methods and materials for containment and cleaning up: Avoid making contact with spilled material, since glutaraldehyde will be absorbed by most shoes. When cleaning up a spill always wear the appropriate protective equipment, including respiratory protection, gloves, protective clothing and eye protection. A self-contained breathing apparatus or respirator and absorbents may be necessary, depending on the size of the spill and the adequacy of ventilation.
Small spills: Wear the correct protective equipment including gloves and protective clothing and cover the liquid with absorbent material. Collect and seal the material and the dirt that has absorbed the spilled material in polyethylene bags and place in a drum for transit to an approved disposal site. Rinse away the remaining spilled material with water to reduce odour, and discharge the rinsate into a municipal or industrial sewer, not into a natural waterway.
Large spills: In case of nasal and respiratory irritation, vacate the room immediately. Personnel cleaning up should be trained and equipped with a self-contained breathing apparatus, or an officially approved or certified full-face respirator equipped with an organic vapor cartridge, glove, and clothing impervious to glutaraldehyde, including rubber boots or shoe protection. Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site.
5.4.   Instructions for safe disposal of the product and its packaging

The biocidal product, when being disposed of in its unused and uncontaminated state should be treated as a hazardous waste according to EC Directive 2008/98/EC.
Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site. If the concentration of glutaraldehyde is up to 2%, deactivate by the addition of aqueous sodium hydroxide solution in an amount sufficient to maintain a pH of 12 for 8 h, followed by neutralization (i.e. neutral pH) with the careful addition of an inorganic acid e.g. hydrochloric acid, before disposal by appropriate means. Any disposal practices must be in compliance with all national and provincial laws and any municipal or local by-laws governing hazardous waste. Do not dump into any sewers, on the ground, or into any body of water. Avoid release to the environment. High-temperature incineration is an acceptable practice glutaraldehyde burns cleanly to carbon dioxide and water.
Containers used to store glutaraldehyde solutions are non refillable. Do not reuse or refill the containers. Containers should be triple or pressure rinsed with water promptly after they are emptied. They can then be offered for recycling or reconditioning for biocidal products, or they can be punctured and disposed of in a sanitary landfill or by other procedures approved by national and local authorities. Send waste liquid from rinsing of used containers to an approved waste handling facility.
5.5.   Conditions of storage and shelf-life of the product under normal conditions of storage

Do not store in and avoid contact with aluminum, carbon steel, copper, mild steel, iron. Avoid contact with amines, ammonia, strong acids, strong bases, strong oxidizers.
Store at temperatures <40 °C

4.5.1.   Use-specific instructions for use

Crude tanks being treated should be at least 10% full before treatment. Do not dispense into empty crude tanks. Use the biocidal product in accordance with local regulatory requirements, and do not exceed recommended dose levels. When treating storage tanks, please note that effective treatment will only be achieved with efficient mixing. Ideally, the biocidal product should be dosed into a flowing crude oil stream in the storage tank inlet.
Other methods of application, such as dumping, will not affect the performance of the biocidal product, but might extend the treatment time required.
Dose 0,025 to 0,4 g glutaraldehyde per liter of water content in crude oil.
Dose level should be proportional to the risk and level of infection, and anticipated time before the next treatment or fluid discharge. Dosing system should be a closed system. Adequate agitation is required to ensure homogeneity throughout the fluid volume.
The dose and frequency strongly depend on the formulation and intended use of the matrix (crude oil) to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.

4.10.1.   Use-specific instructions for use

Glutaraldehyde should be dosed separately from other oil field chemistries such as antifoaming agents, oxygen scavengers, flocculants, or other oxidizing biocides (e.g. chlorite) in order to prevent cross reactivity. Successive addition may therefore be required to optimize performance. If a deaerator is being treated with oxidizing biocides, glutaraldehyde should be dosed downstream of the deaeration unit.
Dose 50 to 1 000 g glutaraldehyde per m3 of injection water.
The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.10.2.   Use-specific risk mitigation measures

If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the produced water. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Produced water containing up to 750 mg/L glutaraldehyde can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.
When applied onshore, preserved fluids must be recycled or disposed of as hazardous waste. If release to the sewer is unavoidable, the concentration shall not exceed 1 mg glutaraldehyde/L.

Preservation of water-based fracturing fluids for the oil and gas industry (i.e. shale gas extraction, wet shale extraction, shale oil extraction, production from tight gas reservoirs, production of coal bed methane and fracturing in conventional reservoirs).




Application method(s)


Method: closed system
Detailed description:
Glutaraldehyde is typically applied in a mixing tank, as it cannot be exposed to open systems such as the hydraulic fracturing pond or other open water sources that make up the hydraulic fracturing pond water. Glutaraldehyde is applied to the mixing tank using automated pumps, together with other chemicals such as but not limited to friction reducers, gelling agents, proppants (sand in case of slick water), corrosion inhibitors.




Application rate(s) and frequency


Application Rate:
Bacteria: curative use, 50 to 1 000  g glutaraldehyde per m3 of fracturing fluid with a contact time of 24 hours. Anaerobic bacteria: preventive use, 150 to 1 000  g glutaraldehyde per m3 of fracturing fluid.
Number and timing of application:
In the hydraulic fracturing industry the application of the biocidal product is typically a single injection, which happens during the actual fracturing. A new biocide addition is only done when the well is re-fractured. Refracturing is rare but can be performed up to 20 times during the lifetime of a well. The lifetime of a well can reach up to 20 years.

4.12.1.   Use-specific instructions for use

Typically applied through a closed system to a mixing tank using a pump. Glutaraldehyde may be used in combination with other chemistries such as friction reducers, gelling agents, proppants, and corrosion inhibitors, and applied together with these chemistries in the mixing tank(s). If used for intermittent treatments during operations, a stream of glutaraldehyde will be directly dosed into the process water stream from a separate tank into a closed system, thereby significantly reducing the chance of exposure.
Dose 50 to 1 000 g glutaraldehyde per m3 of fracturing fluid.
The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.12.2.   Use-specific risk mitigation measures

Preserved fracturing fluids are reused where applicable. If discharged into seawater 0,2 mg glutaraldehyde/L fracturing fluid must not be exceeded. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids.

4.12.3.   Where specific to the use, the particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

See general directions for use. In addition:
Conditions preventing emissions to water:
Emissions to surface water are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be drained to a lined storage area, preventing release to surface water. Sub-surface releases of fluid during the fracturing process are prevented from reaching aquifers through the presence of relatively impermeable formations above the target formation. This limits upward migration of fluid. This is also relevant for recovered fluids that are re-injected for use or disposal. A minimum vertical separation distance between the target formation and aquifer should be respected. National legislation may also require a minimum depth.
Recovered water may finally be discharged via one or more large-scale waste water treatment plants where a combination of physical and biological treatments will reduce emissions to the receiving water.
Conditions preventing emissions to soil:
Emissions, through downward migration are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be prevented from downward migration to soil by the employment of a non-permeable membrane below the well pad. Sludge from treatment works should not be spread on land.
Existence of standard municipal sewage treatment plant
Waste contractors employed to dispose of recovered water, may do so via a waste water treatment plant, depending on the properties of the water and conditions of local regulations.

4.16.1.   Use-specific instructions for use

Injection water is often deaerated before being pumped into the sub-surface. Separation of chemical treatments should be considered when dosing glutaraldehyde, as it may interfere with other common chemistries such as anti-foams, oxygen scavengers, flocculants, and other oxidizing biocides (e.g. chlorite). Successive addition of different chemical packages may be necessary to prevent cross reactivity and to optimize performance. When a deaerator is present and treated with chlorite or a similar oxidizing chemistry, glutaraldehyde is typically dosed after the deaerator.
Dose 50 to 1 000 g glutaraldehyde per m3 injection water.
The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.16.2.   Use-specific risk mitigation measures

If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the produced water. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Produced water containing up to 750 mg/L glutaraldehyde can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.
When applied onshore, preserved fluids must be recycled or disposed of as hazardous waste. If release to the sewer is unavoidable, the concentration shall not exceed 1 mg glutaraldehyde/L.

4.18.1.   Use-specific instructions for use

Glutaraldehyde is typically applied through a closed system to a mixing tank using a pump Glutaraldehyde may be used in combination with other chemistries such as friction reducers, gelling agents, proppants, and corrosion inhibitors, and applied together with these chemistries in the mixing tank(s). If used for intermittent treatments during operations, a stream of glutaraldehyde will be directly dosed into the process water stream from a separate tank into a closed system, thereby significantly reducing the chance of exposure.
Dose 50 to 1 000 g glutaraldehyde per m3 fracturing fluid, in the hydraulic fracturing water matrix.
The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.18.2.   Use-specific risk mitigation measures

Preserved fracturing fluids are reused where applicable. If discharged into seawater 0,2 mg glutaraldehyde/L fracturing fluid must not be exceeded. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Run lab test to determine the soiling dependent dosage and degradation rate in use.

4.18.3.   Where specific to the use, the particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

See general directions for use.
In addition:
Conditions preventing emissions to water:
Emissions to surface water are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be drained to a lined storage area, preventing release to surface water. Sub-surface releases of fluid during the fracturing process are prevented from reaching aquifers through the presence of relatively
impermeable formations above the target formation. This limits upward migration of fluid. This is also relevant for recovered fluids that are re-injected for use or disposal. A minimum vertical separation distance between the target formation and aquifer should be respected. National legislation may also require a minimum depth.
Recovered water may finally be discharged via one or more large-scale waste water treatment plants where a combination of physical and biological treatments will reduce emissions to the receiving water.
Conditions preventing emissions to soil:
Emissions, through downward migration are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be prevented from downward migration to soil by the employment of a non-permeable membrane below the well pad. Sludge from treatment works should not be spread on land.
Existence of standard municipal sewage treatment plant
Waste contractors employed to dispose of recovered water, may do so via a waste water treatment plant, depending on the properties of the water and conditions of local regulations.

5.3.   Particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

IF INHALED: Move to fresh air and keep at rest in a position comfortable for breathing.
If symptoms: Immediately call 112/ambulance for medical assistance.
IF SWALLOWED: If conscious, immediately rinse mouth. Give something to drink, if exposed person is able to swallow. Do NOT induce vomiting. Call 112/ambulance for medical assistance.
IF ON SKIN: Immediately wash skin with plenty of water. Thereafter take off all contaminated clothing and wash it before reuse. Continue to wash the skin with water for 15 minutes. Call a POISON CENTRE or a doctor. If skin irritation or rash occur: Get medical advice.
IF IN EYES: Immediately rinse with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing for at least 15 minutes. Call 112/ambulance for medical assistance.
Information to Healthcare personnel/doctor:
Immediately initiate life support measures, thereafter call a POISON CENTRE.

Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. Spills or discharge to natural waterways is likely to kill aquatic organisms.

Personal precautions, protective equipment and emergency procedures in case of accidental release measures: Evacuate area. Keep upwind of spill. Ventilate area of leak or spill. Only trained and properly protected personnel must be involved in clean-up operations. Use appropriate safety equipment.

Methods and materials for containment and cleaning up: Avoid making contact with spilled material, since glutaraldehyde will be absorbed by most shoes. When cleaning up a spill always wear the appropriate protective equipment, including respiratory protection, gloves, protective clothing and eye protection. A self-contained breathing apparatus or respirator and absorbents may be necessary, depending on the size of the spill and the adequacy of ventilation.
Small spills: Wear the correct protective equipment including gloves and protective clothing and cover the liquid with absorbent material. Collect and seal the material and the dirt that has absorbed the spilled material in polyethylene bags and place in a drum for transit to an approved disposal site. Rinse away the remaining spilled material with water to reduce odour, and discharge the rinsate into a municipal or industrial sewer, not into a natural waterway.
Large spills: In case of nasal and respiratory irritation, vacate the room immediately. Personnel cleaning up should be trained and equipped with a self-contained breathing apparatus, or an officially approved or certified full-face respirator equipped with an organic vapor cartridge, glove, and clothing impervious to glutaraldehyde, including rubber boots or shoe protection. Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site.
5.4.   Instructions for safe disposal of the product and its packaging

The biocidal product, when being disposed of in its unused and uncontaminated state should be treated as a hazardous waste according to EC Directive 2008/98/EC.
Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site. If the concentration of glutaraldehyde is up to 2%, deactivate by the addition of aqueous sodium hydroxide solution in an amount sufficient to maintain a pH of 12 for 8 h, followed by neutralization (i.e. neutral pH) with the careful addition of an inorganic acid e.g. hydrochloric acid, before disposal by appropriate means. Any disposal practices must be in compliance with all national and provincial laws and any municipal or local by-laws governing hazardous waste. Do not dump into any sewers, on the ground, or into any body of water. Avoid release to the environment. High-temperature incineration is an acceptable practice glutaraldehyde burns cleanly to carbon dioxide and water.
Containers used to store glutaraldehyde solutions are non refillable. Do not reuse or refill the containers. Containers should be triple or pressure rinsed with water promptly after they are emptied. They can then be offered for recycling or reconditioning for biocidal products, or they can be punctured and disposed of in a sanitary landfill or by other procedures approved by national and local authorities. Send waste liquid from rinsing of used containers to an approved waste handling facility.
5.5.   Conditions of storage and shelf-life of the product under normal conditions of storage

Do not store in and avoid contact with aluminum, carbon steel, copper, mild steel, iron. Avoid contact with amines, ammonia, strong acids, strong bases, strong oxidizers.

4.9.1.   Use-specific instructions for use

For control of microbial growth in industrial cooling water systems treated with a biocidal product by slug dosing.
Not intended for use in once-through cooling systems. Most cooling towers work continuously over the whole year. The evaporation rate increases in summer when the air is warm but the temperature of the water remains suitable for the micro-organisms all over the year because it is warmed up by the industrial process that generates an excess of heat.
It is recommended to mechanically cleanse dirty systems before starting the treatment with the biocidal product.
Dose in a well-mixed point of the circuit, below the water level.
Typical dose: 1-2 days. Each slug dose lasts 15-30 minutes, depending on the pump capacity and the volume of water in the circuit. Treatment should not exceed 2 days.
Dose 25 to 50 g glutaraldehyde per m3 of water.
The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.9.2.   Use-specific risk mitigation measures

The use is restricted to small cooling systems with a maximum blowdown of 2 m3/h. Waste water must be discharged to the municipal sewer, purified in an on-site industrial sewage treatment plant including a biological treatment step, or directly to surface water via a settling pond that allows sufficient retention.

4.10.1.   Use-specific instructions for use

Glutaraldehyde should be dosed separately from other oil field chemistries such as antifoaming agents, oxygen scavengers, flocculants, or other oxidizing biocides (e.g. chlorite) in order to prevent cross reactivity. Successive addition may therefore be required to optimize performance. If a deaerator is being treated with oxidizing biocides, glutaraldehyde should be dosed downstream of the deaeration unit.
Dose 50 to 1 000 g glutaraldehyde per m3 of injection water.
The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.10.2.   Use-specific risk mitigation measures

If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the produced water. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Produced water containing up to 750 mg/L glutaraldehyde can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.
When applied onshore, preserved fluids must be recycled or disposed of as hazardous waste. If release to the sewer is unavoidable, the concentration shall not exceed 1 mg glutaraldehyde/L.

Application method(s)


Method: closed system
Detailed description:
Glutaraldehyde is typically applied in a mixing tank, as it cannot be exposed to open systems such as the hydraulic fracturing pond or other open water sources that make up the hydraulic fracturing pond water.Glutaraldehyde is applied to the mixing tank using automated pumps, together with other chemicals such as but not limited to friction reducers, gelling agents, proppants (sand in case of slick water), corrosion inhibitors.




Application rate(s) and frequency


Application Rate:
Bacteria: curative use, 50 to 1 000  g glutaraldehyde per m3 of fracturing fluid with a contact time of 24 hours. Anaerobic bacteria: preventive use, 150 to 1 000  g glutaraldehyde per m3 of fracturing fluid.
Number and timing of application:
In the hydraulic fracturing industry the application of the biocidal product is typically a single injection, which happens during the actual fracturing. A new biocide addition is only done when the well is re-fractured. Refracturing is rare but can be performed up to 20 times during the lifetime of a well. The lifetime of a well can reach up to 20 years.

4.12.1.   Use-specific instructions for use

Typically applied through a closed system to a mixing tank using a pump. Glutaraldehyde may be used in combination with other chemistries such as friction reducers, gelling agents, proppants, and corrosion inhibitors, and applied together with these chemistries in the mixing tank(s). If used for intermittent treatments during operations, a stream of glutaraldehyde will be directly dosed into the process water stream from a separate tank into a closed system, thereby significantly reducing the chance of exposure.
Dose 50 to 1 000 g glutaraldehyde per m3 of fracturing fluid.
The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.12.2.   Use-specific risk mitigation measures

Preserved fracturing fluids are reused where applicable. If discharged into seawater 0,2 mg glutaraldehyde/L fracturing fluid must not be exceeded. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids.

4.12.3.   Where specific to the use, the particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

See general directions for use. In addition:
Conditions preventing emissions to water:






 


Emissions to surface water are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be drained to a lined storage area, preventing release to surface water. Sub-surface releases of fluid during the fracturing process are prevented from reaching aquifers through the presence of relatively impermeable formations above the target formation. This limits upward migration of fluid. This is also relevant for recovered fluids that are re-injected for use or disposal. A minimum vertical separation distance between the target formation and aquifer should be respected. National legislation may also require a minimum depth/










 


Recovered water may finally be discharged via one or more large-scale waste water treatment plants where a combination of physical and biological treatments will reduce emissions to the receiving water.




Conditions preventing emissions to soil:
Emissions, through downward migration are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be prevented from downward migration to soil by the employment of a non-permeable membrane below the well pad. Sludge from treatment works should not be spread on land.
Existence of standard municipal sewage treatment plant
Waste contractors employed to dispose of recovered water, may do so via a waste water treatment plant, depending on the properties of the water and conditions of local regulations.

4.16.1.   Use-specific instructions for use

Injection water is often deaerated before being pumped into the sub-surface. Separation of chemical treatments should be considered when dosing glutaraldehyde, as it may interfere with other common chemistries such as anti-foams, oxygen scavengers, flocculants, and other oxidizing biocides (e.g. chlorite). Successive addition of different chemical packages may be necessary to prevent cross reactivity and to optimize performance. When a deaerator is present and treated with chlorite or a similar oxidizing chemistry, glutaraldehyde is typically dosed after the deaerator.
Dose 50 to 1 000 g glutaraldehyde per m3 injection water.
The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.16.2.   Use-specific risk mitigation measures

If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the produced water. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Produced water containing up to 750 mg/L glutaraldehyde can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.
When applied onshore, preserved fluids must be recycled or disposed of as hazardous waste. If release to the sewer is unavoidable, the concentration shall not exceed 1 mg glutaraldehyde/L.

4.18.1.   Use-specific instructions for use

Glutaraldehyde is typically applied through a closed system to a mixing tank using a pump Glutaraldehyde may be used in combination with other chemistries such as friction reducers, gelling agents, proppants, and corrosion inhibitors, and applied together with these chemistries in the mixing tank(s). If used for intermittent treatments during operations, a stream of glutaraldehyde will be directly dosed into the process water stream from a separate tank into a closed system, thereby significantly reducing the chance of exposure.
Dose 50 to 1 000 g glutaraldehyde per m3 fracturing fluid, in the hydraulic fracturing water matrix.
The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.
4.18.2.   Use-specific risk mitigation measures

Preserved fracturing fluids are reused where applicable. If discharged into seawater 0,2 mg glutaraldehyde/L fracturing fluid must not be exceeded. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Run lab test to determine the soiling dependent dosage and degradation rate in use.

4.18.3.   Where specific to the use, the particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

See general directions for use. In addition:
Conditions preventing emissions to water:
Emissions to surface water are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be drained to a lined storage area, preventing release to surface water. Sub-surface releases of fluid during the fracturing process are prevented from reaching aquifers through the presence of relatively
impermeable formations above the target formation. This limits upward migration of fluid. This is also relevant for recovered fluids that are re-injected for use or disposal. A minimum vertical separation distance between the target formation and aquifer should be respected. National legislation may also require a minimum depth
Recovered water may finally be discharged via one or more large-scale waste water treatment plants where a combination of physical and biological treatments will reduce emissions to the receiving water.
Conditions preventing emissions to soil:
Emissions, through downward migration are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be prevented from downward migration to soil by the employment of a non-permeable membrane below the well pad. Sludge from treatment works should not be spread on land.
Existence of standard municipal sewage treatment plant
Waste contractors employed to dispose of recovered water, may do so via a waste water treatment plant, depending on the properties of the water and conditions of local regulations.

5.3.   Particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

IF INHALED: Move to fresh air and keep at rest in a position comfortable for breathing.
If symptoms: Immediately call 112/ambulance for medical assistance.
IF SWALLOWED: If conscious, immediately rinse mouth. Give something to drink, if exposed person is able to swallow. Do NOT induce vomiting. Call 112/ambulance for medical assistance.
IF ON SKIN: Immediately wash skin with plenty of water. Thereafter take off all contaminated clothing and wash it before reuse. Continue to wash the skin with water for 15 minutes. Call a POISON CENTRE or a doctor. If skin irritation or rash occur: Get medical advice.
IF IN EYES: Immediately rinse with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing for at least 15 minutes. Call 112/ambulance for medical assistance.
Information to Healthcare personnel/doctor:
Immediately initiate life support measures, thereafter call a POISON CENTRE.

Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. Spills or discharge to natural waterways is likely to kill aquatic organisms.

Personal precautions, protective equipment and emergency procedures in case of accidental release measures: Evacuate area. Keep upwind of spill. Ventilate area of leak or spill. Only trained and properly protected personnel must be involved in clean-up operations. Use appropriate safety equipment.

Methods and materials for containment and cleaning up: Avoid making contact with spilled material, since glutaraldehyde will be absorbed by most shoes. When cleaning up a spill always wear the appropriate protective equipment, including respiratory protection, gloves, protective clothing and eye protection. A self-contained breathing apparatus or respirator and absorbents may be necessary, depending on the size of the spill and the adequacy of ventilation.
Small spills: Wear the correct protective equipment including gloves and protective clothing and cover the liquid with absorbent material. Collect and seal the material and the dirt that has absorbed the spilled material in polyethylene bags and place in a drum for transit to an approved disposal site. Rinse away the remaining spilled material with water to reduce odour, and discharge the rinsate into a municipal or industrial sewer, not into a natural waterway.
Large spills: In case of nasal and respiratory irritation, vacate the room immediately. Personnel cleaning up should be trained and equipped with a self-contained breathing apparatus, or an officially approved or certified full-face respirator equipped with an organic vapor cartridge, glove, and clothing impervious to glutaraldehyde, including rubber boots or shoe protection. Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site.
5.4.   Instructions for safe disposal of the product and its packaging

The biocidal product, when being disposed of in its unused and uncontaminated state should be treated as a hazardous waste according to EC Directive 2008/98/EC.
Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site. If the concentration of glutaraldehyde is up to 2%, deactivate by the addition of aqueous sodium hydroxide solution in an amount sufficient to maintain a pH of 12 for 8 h, followed by neutralization (i.e. neutral pH) with the careful addition of an inorganic acid e.g. hydrochloric acid, before disposal by appropriate means. Any disposal practices must be in compliance with all national and provincial laws and any municipal or local by-laws governing hazardous waste. Do not dump into any sewers, on the ground, or into any body of water. Avoid release to the environment. High-temperature incineration is an acceptable practice glutaraldehyde burns cleanly to carbon dioxide and water.
Containers used to store glutaraldehyde solutions are non refillable. Do not reuse or refill the containers. Containers should be triple or pressure rinsed with water promptly after they are emptied. They can then be offered for recycling or reconditioning for biocidal products, or they can be punctured and disposed of in a sanitary landfill or by other procedures approved by national and local authorities. Send waste liquid from rinsing of used containers to an approved waste handling facility.
5.5.   Conditions of storage and shelf-life of the product under normal conditions of storage

Do not store in and avoid contact with aluminum, carbon steel, copper, mild steel, iron. Avoid contact with amines, ammonia, strong acids, strong bases, strong oxidizers.
