Guidelines for the Reduction of Dyes Released from Pulp and Paper Mills (2024)

Foreward

The Minister of the Environment issued the Guidelines for the Reduction of Dyes Released from Pulp and Paper Mills (the Guidelines) under subsection 54(1) of the Canadian Environmental Protection Act, 1999 to limit triarylmethane dye quantities released in the final effluent.

Note that the primary instrument to manage pulp and paper and paper effluent is the Pulp and Paper Effluent Regulations (PPER) under the Fisheries Act. These Regulations establish effluent release limits for biochemical oxygen demand and total suspended solids and prohibit the discharge of acutely lethal effluent to fish. The Guidelines may assist facilities in predicting when their concentrations of triarylmethane dye in wastewater effluent may have an adverse effect on receiving waters and allow them to adjust their supplies and processes accordingly. Thus, the Guidelines are complementary to the PPER.

The Minister of the Environment recommends that the appropriate regulatory agency adopt the annexed Guidelines as baseline standards for the levels of dyes released from pulp and paper mills. However, local conditions, such as density of industrial development, topography and other environmental considerations, may necessitate the adoption of more stringent requirements than those suggested in these Guidelines. Ongoing advances in reduction strategies and in technology should also be taken into account.

This publication of the Guidelines supersedes the original December 2013 publication.

1. Definitions

2. Scope

These Guidelines apply to a mill that uses at least one of the dyes listed in Appendix 1. The Guidelines set out standards and good practices to observe in order to limit dye quantities released in the final effluent.

The standards and good practices set out in these Guidelines may be observed using currently available knowledge, methods and technologies from the supplier of these substances as well as from the pulp and paper industry.

3. Performance guidelines
  1. 3.1. The retention of dyes used in the pulp and paper process that are subject to these Guidelines should respect the standards set out in Appendix 1.
  2. 3.2. The removal of solids in the primary wastewater treatment system, which allows for dye removal by adsorption, should respect the standards set out in Appendix 1.
  3. 3.3. A containment plan should be in place to prevent the release of dyes into the environment or an effluent treatment system during the storage (for example fixed supply tank, tote, drum or any other container), handling and disposal of dye.
    1. 3.3.1 A secondary containment should be configured with a capacity equal to or greater than
      • 110% of the capacity of the tank if there is only one tank; or
      • 100% of the capacity of the largest tank plus 10% of the aggregate capacity of all other tanks.
    2. 3.3.2 A method for the collection or recirculation of dye should be in place before the purge of dye from equipment, piping or tank containing dyes in order to prevent the release of dye into water.
4. Declaration of the operator

The operator of a mill that is subject to these Guidelines should inform, in writing, the Minister of the Environment of the intention to implement the Guidelinesfootnote 2

The Minister of the Environment should also be notified, in writing,footnote 3 if the operator permanently ceases to use any of the dyes listed in Appendix 1.

5. Monitoring

The operator of a mill subject to these Guidelines should measure annually whether activities are carried out in conformity with the standards specified in Appendix 1 and should record the quantity of the dye released incidentally into the environment or to an effluent treatment system during its storage, handling or disposal.

6. Report

The operator of a mill that is subject to the Guidelines should provide a conformity evaluation reportfootnote 3 to the Minister of the Environment that includes the following:

The operator should provide the first report to the Minister of the Environment three years after the final publication of the 2024 amended Guidelines for MG, BV3, BV4 and BB7. This requirement is not applicable for MAPBAP acetate.

Subsequently, a conformity evaluation report should be submitted annually to the Minister of the Environment only if the standards in Appendix 1 were not respected or if at least one of the dyes subject to these Guidelines were released incidentally to the environment or to an effluent treatment system as a result of the storage, handling or disposal of dye for that calendar year.

7. Record Keeping

The operator of a mill that is subject to these Guidelines should keep a record of all relevant information and documents including test data for a period of at least five years beginning on the date of their creation. The record should be available to the Minister of the Environment on request.

Appendix 3: Proposed method for measuring dye retention on fibres

Equipment

Products

Procedure

  1. Preparation of dye solution:
    • a. Dilute the dye to 0.2 g/L (Ci) with deionized water.
  2. Use the spectrophotometer to determine the maximum absorption wavelength and develop a “concentration-absorbance” curve using that value. Establish the minimum dye concentration that can be measured with this instrument (minimum measurable value).
  3. Pulp retention measure:
    • a. Dilute 2.00 g of dry pulp in deionized water until you achieve a 1% consistency
    • b. Agitate at 50 °C for 2 minutes or until no fibre flocs remain
    • c. Filter with the Büchner and filter paper and keep the filtrate in a beaker
    • d. Measure the filtrate absorbance (A int) at the wavelength established in Step 2 in order to estimate the interference caused by suspended solids and the filtrate colour
    • e. Measure the quantity of dry pulp on the filter paper
    • f. Calculate the pulp retention. A 99% minimum value is required to minimize interference with the absorption measure. For lower retention, increase the quantity of pulp or use a lower-porosity fibreglass filter.
  4. Dye retention measure:
    • a. Weigh 2.00 g of dry pulp
    • b. Add 180 ml of deionized water
    • c. Add 20 ml of the dye solution (Vi) to the pulp to obtain a concentration of 0.002 g pure dye/g dry pulp
      • The final consistency of the pulp should be 1%
    • d. Agitate at 50 °C for 2 minutes or until no fibre flocs remain
    • e. Filter with the Büchner and filter paper
    • f. Measure the filtrate volume (Vf)
    • g. Measure the filtrate absorbance (Af)
    • h. Calculate the corrected absorbance (A corr) = Af − A int (from Step 3.d.)
    • i. Calculate the dye concentration in the filtrate (Cf) with the “concentration-absorbance” curve (Step 2), using the corrected absorbance (A corr)
    • j. Calculate the quantity of (pure) dye in the filtrate (Df) = Vf × Cf [g]
    • k. Calculate the initial quantity of (pure) dye (Di) = Vi × Ci [g]
    • l. Measure the pH and conductivity of the filtrate (for reference only)
    • m. Calculate the dye retention = (Di − Df) / Di ×100%
    • n. Repeat Step 4 twice. Record the mean retention, pH and conductivity.
