An Order amending the Domestic Substances List to rescind the Significant New Activity provisions on CPAOBP (CAS RN 78952-70-2) was published.
Final Screening Assessment:
“Certain Diarylide Yellow Pigments
In October 2014, the final screening assessment for five substances was released and the related Notice was published in the Canada Gazette Part I: Vol. 148 No. 41 – October 11, 2014 ( PDF Version – 1,015 K).
The final screening assessment concluded that these five substances do not meet any of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), therefore the Ministers of the Environment and of Health proposed to take no further action on these substances at this time under the Act. No proposed risk management approach document was prepared.
Two substances in this subgroup, BPAOPB (CAS RN 7147-42-4; Batch 6) and Pigment Brown 22 (CAS RN 29398-96-7; Batch 7), were previously assessed under the Challenge Initiative of the Chemicals Management Plan. It was concluded that they did not pose a risk to the environment or to human health as set out in section 64 of CEPA 1999. These conclusions remain unchanged. BPAOPB is used as an analogue in this screening assessment due to its structural similarity to the five diarylide yellow pigments. Information related to BPAOPB is used to inform this draft screening assessment. Pigment Brown 22 is not included in this draft screening assessment, as no new information was received since its assessment in 2010 and because it does not inform the assessment of the five diarylide yellow pigments.”
