Chromium Electroplating, Chromium Anodizing and Reverse Etching Regulations
Canadian Environmental Protection Act, 1999 

1.1 Background

On February 4th 1994, due to their toxic nature, hexavalent chromium compounds were added to the list of toxic substances of CEPA. In 2009, Environment Climate Change Canada (ECCC) published the Regulations with the objective of reducing emissions of hexavalent chromium compounds to the environment. The Regulations Amending the Chromium Electroplating, Chromium Anodizing and Reverse Etching Regulations were published on April 1, 2020 in order to improve consistency between the French and English versions of the Regulations, improve the clarity of the regulatory text related to laboratory accreditation, and provide regulated parties with more flexibility to choose from various tensiometers available on the market by removing reference to an outdated American Society for Testing and Materials (ASTM) technical standard.

1.2 Coming into force

The Regulations have been in force since their publication in the Canada Gazette, Part II, in 2009.

1.3 Application

The Regulations apply to any person that uses a solution containing hexavalent chromium at a facility using^{Footnote 1}  50 kg or more of chromium trioxide (CrO₃) per calendar year to do one of the following:

• chromium electroplating
• chromium anodizing
• reverse etching

Figure 1 may help you determine some of your responsibilities under the Regulations.

1.4 Purpose

The purpose of the Regulations is to reduce the air emissions of hexavalent chromium compounds from facilities that perform the following activities:

• chromium electroplating
• chromium anodizing
• reverse etching

1.5 Possible control methods

The Regulations allow 3 methods to reduce the release of hexavalent chromium compounds. Requirements for each method are described in this guidance document and within the referenced sections of the Regulations:

1. Chapter 4: Use of a point source (sections 4 to 6 of the Regulations)
2. Chapter 5: Limiting the surface tension (section 7 of the Regulations)
3. Chapter 6: Use of a tank cover (sections 8 to 10 of the Regulations)

Related links:

• Appendix A: summary of release limits

2. General requirements

The general requirements are in section 3 of the Regulations, sub-sections 3(1) to 3(3).

• 30 days prior to commencing operations, a control method notice must be submitted indicating, for each tank, the method used to control the release of hexavalent chromium compounds
• 30 days prior to any changes from the most recent control method notice, a new notice must be submitted

Related links:

• Appendix D: control method notice form

2.1 New facility notice requirements

A new facility is a facility at which chromium electroplating, chromium anodizing or reverse etching activities commence, are carried out in a tank, and 50 kg or more of chromium trioxide (CrO₃) is used per calendar year for any of those activities.

For a new facility starting operation, the person representing the facility must submit a control method notice indicating, for each tank, the method to be used to control the release of hexavalent chromium compounds at least 30 days before beginning any activities. If the surface tension limiting method is chosen, the notice must also state which device will be used to measure surface tension: a tensiometer or a stalagmometer.

2.2 Change in control method notice requirements

Any person that intends to change either the method of controlling the release of hexavalent chromium compounds or the surface tension measurement method must submit a control method notice. The control method notice must be submitted at least 30 days before the change.

3. Additional requirements

If it has been determined that the Regulations apply to you, there exists the additional requirement of reporting to the National Pollutant Release Inventory (NPRI) for hexavalent chromium releases, disposals, and recycling, regardless of other NPRI requirements.

Further information regarding this requirement can be found on the government of Canada NPRI webpage.

4. Use of a point source

Should a point source control be the method selected for controlling the release of hexavalent chromium compounds, the requirements for the use of a point source control are described in sections 4 through 6 of the Regulations.

4.1 Method summary

The Regulations allow the release of hexavalent chromium compounds to be limited by using a control device and meeting a point source release limit. This control method requires that hexavalent chromium compounds released from chromium electroplating, chromium anodizing and reverse etching processes be collected and directed to a control device. Composite mesh beds and packed bed scrubbers are examples of control devices that could be used to reduce the releases of hexavalent chromium compounds. After passing the control device, the treated air stream is released into the environment from a stack.

4.2 Conditions

Section 4 of the Regulations provide the conditions that must be met if a point source control device is being used. A control device in the emission collection system must not release more than 0.03 mg/dscm of hexavalent chromium. If hexavalent chromium is not measured separately from another chromium compound, then the total chromium emissions must not exceed the above mentioned limit. Moreover, an inspection and maintenance plan must be prepared and inspections must be carried out at least every 3 months (see chapter 4.7 of this guide).

4.3 Release test performed after the Regulations came into force

As per sub-section 5(1) of the Regulations, a release test must be performed at each point source to establish compliance with the 0.03 mg/dscm limit.

A new release test must be performed within 5 years of the day of the most recent test that demonstrates results in compliance with the Regulations.

4.4 Process modifications requiring a new release test within 75 days after completing the operation

Sub-section 5(3) of the Regulations specifies that a new release test within 75 days must be performed if any of the following modifications are made:

1. replacing a control device
2. the total surface area of the solution in 1 or more tanks connected to a control device is increased by more than 25%
3. installing 1 or more tanks to increase, by more than 25%, the total surface area of the solution in the tanks connected to a control device
4. making changes to the ventilation system connected to a tank that affects the velocity or the flow rate of the ventilation other than a change that results from removing or isolating a tank from that system

4.5 Conditions applicable to all release tests

The conditions that are applicable to all release tests are provided in sub-section 5(4) of the Regulations. In general, when performing a release test, the following technical parameters should be observed:

1. the test must be performed under representative operating conditions which are defined such that the rectifier amperage should be equal to the average of the preceding 30 days of use, and the connected ventilation system should not be altered by the introduction of additional dilution air
2. the control equipment must be sampled in accordance with generally accepted methods (such as EPA method 306)
3. each of the 3 2-hour sampling runs must collect a minimum of 1.7 dscm of exhaust gas
4. the samples must be analyzed by a Canadian laboratory accredited under the standard ISO/IEC 17025 or under the Environment Quality Act, CQLR, c. Q-2, and the scope of its accreditation must include the parameters that are analyzed
5. The average of the results from the 3 sampling runs must not exceed 0.03 mg/dscm of hexavalent chromium or total chromium

In addition, the analysis must be carried out with an analytical method whose precision and accuracy are based on a minimum of 7 replicate samples and that satisfies the following requirements:

1. a method detection limit of at least 8 μg/L of chromium
2. a precision of 5% relative standard deviation at 10 times the method detection limit
3. an accuracy of 100% ± 5% based on analyte recovery at least 10 times the method detection limit

4.6 Requirements to notify the Minister of the release test

As per sub-section 5(5) of the Regulations, a release test notice, specifying the civic address of the facility, must be submitted at least 30 days before performing the release test and specify the 3-day period within which the test will be performed.

• Appendix E: release test notice form

4.7 Inspection and maintenance of control devices

As per section 6 of the Regulations an inspection and maintenance plan must be prepared and implemented if a point source control method is used. Control devices must be inspected at least every 3 months to verify the following:

1. the control device surfaces and all its components are free from any fracture or deformation
2. the ductwork between the control device and any tank does not leak and is not broken
3. the filtering media within the control device are free of any blockage and there is no buildup that would affect the operation of the device
4. there are no visible signs of hexavalent chromium compounds at the exit of the control device

For record keeping purposes, pictures may be helpful and are encouraged to be taken of the inspected items mentioned above.

If a composite mesh pad system is used, the inspection and maintenance plan must also include the following tasks:

1. verifying that there is no buildup on the mesh pads
2. if the mesh pads are not continuously washed, washing the mesh pads for at least 20 minutes at least twice during every 8 hours of operation with an interval of at least 3 hours between washes, or in accordance with the manufacturer’s recommendations

If any defect is identified in the course of an inspection, the defect must be corrected before resuming any plating activities. Note that there are no reporting requirements under this section. However, inspection and maintenance records must be kept. The information that must be recorded includes the following:

1. the date on which the inspection and maintenance tasks were performed
2. a description of each inspection and maintenance task performed
3. the date on which each defect was identified
4. a description of the measures taken to correct the defect

Consideration should be given to saving any pictures that are taken during the inspection with the inspection records.

4.8 Reporting requirements for all release tests

As per sub-section 11(1) of the Regulations, within 75 days of the last sample being taken for the purpose of a release test, a report for each point source tested must be submitted and contain the following information:

1. the date the sampling was performed and the time the sampling was started and completed
2. the test results including the concentration (mg/dscm) of hexavalent chromium, if measured separately, or of total chromium:
   1. measured for each of the 3 sampling runs
   2. calculated as an average concentration for those runs
3. the location on a floor plan of the point source and any tanks, control devices and fans connected to this point source at the time the sampling was performed
4. the test method used

5. Limiting the surface tension

Should controlling the release of hexavalent chromium compounds be undertaken by limiting the surface tension, the requirements for this method are described in section 7 of the Regulations.

5.1 Method summary

During chromium electroplating, chromium anodizing and reverse etching processes, hydrogen and oxygen gases are released at the cathode and anode. These gases, which are generated by the electrolytic decomposition of water (H₂O) and the chromate ion (CrO₃^2-), form bubbles that rise to the surface of the solution. Chromic acid mist is produced when these gas bubbles burst at the surface of the solution, spraying fine particles of solution into the atmosphere.

By adding a fume suppressant to reduce the surface tension of the plating solution, the energy of the bursting is reduced, much less chromic acid mist is formed and fewer hexavalent chromium compounds are released.

5.2 Fume suppressants

Fume suppressants, also known as aqueous film-forming foam, containing perfluorooctane sulphonate, its salts and its precursors (collectively referred to as PFOS), have been regulated by Environment and Climate Change Canada (ECCC) since 2008. In 2016, PFOS were added to the Prohibition of Certain Toxic Substances Regulations which prohibit the manufacture, use, sale, offer for sale and import of PFOS.

5.3 Conditions

The conditions for controlling the release of hexavalent chromium compound by limiting the surface tension are described in sub-sections 7(1), 7(2), and 7(4) of the Regulations. The surface tension of the solution in the tank must be maintained at a value less than 35 dyn/cm if the surface tension is measured with a tensiometer or 45 dyn/cm if the surface tension is measured with a stalagmometer. The Regulations stipulate 2 different surface tension limits because the stalagmometer produces consistently higher surface tension readings for the same sample solution than those obtained with a tensiometer.

• To ensure that these measurement devices are used properly, the surface tension must be measured in accordance with the manufacturer’s instructions.

5.4 Frequency of measurement

As per sub-sections 7(3) and 7(5) of the Regulations, the surface tension must be measured and recorded, for each tank, once every day during which the tank is used. The surface tension measurements must be taken at least 16 hours apart. If a tank is not used for more than 24 consecutive hours, prior to resuming its use, the surface tension must be measured and meet the conditions outlined above.

5.5 Reporting requirements

Reporting requirements are provided in sub-sections 11(2) and 11(3) of the Regulations for regulatees controlling the release of hexavalent chromium compounds by limiting the surface tension. For surface tension measurements recorded from January 1 to June 30, a report must be submitted no later than July 31 of the same calendar year. For surface tension measurements recorded from July 1 to December 31, a report must be submitted no later than January 31 of the next calendar year.

6. Use of a tank cover

Should a tank cover be the method selected for controlling the release of hexavalent chromium compounds, the requirements for the use of a tank cover are described in sections 8 through 10 of the Regulations.

6.1 Method summary

The Regulations allow the use of a tank cover over a chromium electroplating, chromium anodizing or reverse etching tank to control the release of hexavalent chromium compounds. Hydrogen and oxygen gas generated during the plating process pass through a selective membrane and are released into the plating room environment. Water vapour and hexavalent chromium compounds do not pass through the membrane, but condense within the confines of the tank cover and drain back to the tank.

At the end of each plating cycle, an evacuation process removes the air under the cover (which may contain hexavalent chromium compounds) through a high-efficiency particular air (HEPA) filter before the cover can be opened.

6.2 Conditions

Section 8 of the Regulations describes the conditions that must be met when using a tank cover. If the release of hexavalent chromium compounds is controlled by using a tank cover, it must be ensured that the cover completely encloses the open surface area of the tank and that the cover has a seal that joins the cover to the tank. Every tank using a tank cover, the closed tank cover system must have a membrane inset in the cover that has a minimum surface area of 0.28 m²/kA of current and pore openings not larger than 1 µm. Finally, the cover must have an evacuation device that is attached to the outside of the cover and that has a HEPA filter with pore openings no larger than 0.1 µm.

6.3 Inspection and maintenance of a tank cover

As per sub-sections 9(1) through 9(3) of the Regulations, if a tank cover is in use, an inspection and maintenance plan must be prepared and implemented. That plan must be in accordance with the instructions of the manufacturer of the tank cover and must at least include the following tasks:

1. induction of an external pressure on the membrane while the tank cover is closed and the tank is in operation to verify that the membrane moves outward (each day that the cover is used)
2. drainage of the air inlet by purging the air valves (at the end of each day the tank is operated or end of each cycle)
   1. if the membrane does not move inward during the purge, then a verification of the seal of the tank cover must be performed as per the manufacturer instructions
3. inspection of the access doors and membranes to determine whether the tank cover leaks or if there are any tears in the membrane (at least once a week)
4. drainage of the evacuation device into the tank (at least once a week)
5. inspection of the membrane for perforations using a light source (at least once a month)
6. inspection of all clamps that hold the tank cover closed and replacement of any defective clamps (at least once a month)
7. inspection of all piping to and from the evacuation device to verify that there are no leaks and no evidence of deterioration (at least once every 3 months)
8. replacement of the HEPA filter on the evacuation device (at least once a year)

If any defect is identified in the course of an inspection, the defect must be corrected before resuming any plating activities. There are no reporting requirements to submit under this section, but records must be kept. The information that must be recorded is the following:

1. the date on which inspections and maintenance tasks were performed
2. a description of each inspection and maintenance task performed
3. the date on which each defect was identified
4. a description of the measures taken to correct the defect

Pictures may be helpful and are encouraged to be taken of in order to document the actions taken and consideration should be given to keeping any pictures with the inspection records.

6.4 Smoke test

Section 10 of the Regulations specifies that before the first use of the tank cover and every 3 months thereafter, a smoke test must be performed to determine whether the cover leaks.

The Regulations specify technical parameters you must observe when performing a smoke test. During the test, the smoke test device must generate 15 to 30 m³ of smoke for every 2 m² of tank surface. This process must allow the smoke test device to burn completely inside the tank while the tank cover is closed and to fill the space under the cover with smoke. If the operator detects any release of smoke, the cover must be repaired and the smoke test must be repeated until there are no leaks of smoke from the cover.

For every smoke test conducted, the following information must be recorded:

1. date on which the smoke test was conducted
2. results of the test
3. name of the manufacturer of the smoke test device
4. a description of the steps taken in conducting the test
5. the sequence in which those steps were performed
6. if applicable, the location of any leaks and the measures taken to correct any defects

7. Report of release into the environment

The Regulations include the requirements for reporting a release into the environment under section 12. In the case of, or likelihood of a release of hexavalent chromium compounds into the environment, in contravention of these Regulations, the department must be notified of the release and a written report must be submitted, as soon as possible.

The written report must be provided to the regional director of the environmental enforcement division in the region where the release or likelihood of a release took place.

The written report must contain the following information:

1. the name, civic address and telephone number of the person submitting the report
2. the civic address of the facility where the release occurred or is likely to occur
3. in the case of a release, the date, time, duration and location of the release
4. in the case of the likelihood of a release, the date, time and location where the release is likely to occur
5. the estimated quantity of hexavalent chromium compound that was released or is likely to be released
6. a description of the circumstances leading to the release or likely release, including identification of its cause, if known, and any corrective action taken
7. a description of measures taken to remedy, reduce or mitigate any danger that results from the release or that may reasonably be expected to result if the release were to occur
8. the identification of all persons and agencies notified as a result of the release or likely release
