substances can negatively affect our health and environment when released in a certain

human health and/or the environment as per the criteria set out under section 64 of the 
Canadian Environmental Pr otection Act, 1999 (CEPA 1999).  
The objective of the proposed Order Adding Toxic Substances to Schedule 1 to the Canadian 
Environmental Protection Act, 1999 (hereinafter referred to as the proposed Order), made 
under subsection 90(1) of CEPA 1999,  is to add the following substances to the List of Toxic 
Substances in Schedule 1 of CEPA 1999:  
•  Sulfuric acid, diethyl ester (CAS No. 64-67-5) , hereafter referred to as “diethyl sulfate,”  
•  Sulfuric acid, dimethyl ester (CAS No. 77-78-1) , hereafter referred to as “dimethyl sulfate,” 
and  
•  Benzenamine, N-phenyl-, re action products with styrene a nd 2,4,4-trimethylpentene (CAS 
No. 68921-45-9), hereafter re ferred to as “BNST.”  G/TBT/N/CAN/283
