Phenol, methylstyrenated was first assessed in 2008 as a part of the Final Screening Assessment for Potentially Toxic Substances [145 Persistent Bioaccumulative and inherently Toxic (PBiT) substances] and was found not to meet any criteria set out in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). However, due to concerns regarding its hazardous properties and its potential for bioaccumulation and persistence in the environment, the Significant New Activity provisions of CEPA 1999 were applied. Since 2015, multiple Significant New Activity Notifications have been received, resulting in the establishment of ministerial conditions (Nos. 19668 and 19768) and the decision to conduct a further screening assessment for this substance.
