List of release guidelines

This is a list of our environmental release guidelines for preserving the quality of the environment. 

Proposed release guidelines

Certain azo disperse dyes (consultation from February 23, 2019 to April 24, 2019)

Consultation document on the proposed release guidelines

Objective: The proposed release guidelines aim to reduce the release of Disperse Yellow 3 and other azo disperse dyes into the environment, that may occur during the formulation of textile dyes and the dyeing of textiles.

Release guidelines in effect

Combustion turbines

Overview of the combustion turbines release guidelines

Objective: The release guidelines recommend nitrogen oxide (NOx) emission limits for new natural gas-fuelled stationary combustion turbines.

Pulp and paper dyes

Overview of the pulp and paper dyes release guidelines

Objective: The release guidelines aim to limit releases of dyes in the final effluent from pulp and paper mills.

Results to date: As of 2016, there were 3 pulp and paper mills that use dyes containing MAPBAP acetate. All facilities are meeting the objective of the guidelines.

Ethylene oxide

Overview of the ethylene oxide release guidelines

Objective: The release guidelines recommend best practices to limit releases of ethylene oxide to the environment from sterilization applications.

Release of ammonia in wastewater effluents

Read the ammonia release guidelines

Objective: An objective for ammonia releases to surface water is to achieve and maintain a concentration of ammonia in the effluent that will ensure the protection of freshwater life.

Thermal electricity generation

Read the thermal electricity release guidelines

Objective: The release guidelines are part of continuing efforts to diminish the emissions of air-polluting discharges to the atmosphere, and will contribute to that end by restricting such discharges from future additions to electric generating system capacity. The guidelines indicate the quantities and concentrations above which nitrogen oxides, particulate matter and sulphur dioxide should not be emitted from fossil fuel-fired steam-driven electricity generating units, operated in whole or in part for the purpose of the sale of electricity to industry, commerce, or the public.

Volatile organic compounds in consumer products

Read the volatile organic compounds guidelines

Objective: The guidelines recommend volatile organic compound (VOC) content limits for 23 consumer product categories.

Glycol

Overview of the glycol guidelines

Objective: The guidelines recommend a concentration limit for the discharge of glycols to surface water resulting from aircraft de-icing and anti-icing activities.
