Comment on: Proposed new requirements for reporting triarylmethane dyes to the National Pollutant Release Inventory
Current status: Closed
This consultation ran from October 11, 2023, to December 15, 2023.
We consulted Canadians about National Pollutant Release Inventory (NPRI) reporting requirements for five triarylmethane dyes. Industry uses triarylmethane dyes as colorants in medical devices, ink, toner, paints and coatings, and paper products.
Who was the focus of this consultation
We engaged with:
- a multi-stakeholder work group including:
- industry associations
- environmental non-government organizations
- Indigenous organizations
- members of the public
Key questions for discussion
We proposed:
- adding four individual substances under Part 1, Group B with reporting thresholds of 1,000 kilograms and 1% concentration
- lowering the current reporting threshold of C.I. Basic Green 4 from 10 tonnes to 1,000 kilograms and rename it to Malachite Green
we sought ideas and input around the following topics:
- should NPRI add the four triarylmethane dyes and lower the reporting threshold for Malachite Green?
