Summary of the final regulatory action:

A prohibition to import and manufacture was published on July 5, 1997, in the Canada Gazette, Part I, in the notice entitled Conditions and Prohibitions for the Manufacture and Import of Substances New to Canada that are Suspected of Being Toxic.

The proposed Tributyltetradecylphosphonium Chloride Regulations, pursuant to section 34 of the Canadian Environmental Protection Act (CEPA), will prohibit the use, processing, offer for sale, sale and importation into Canada of TTPC and impose conditions on its manufacture. The Regulations will permit the manufacture of the substance for export purpose only, if the manufacturer:

·provides an export notice to the receiving country and to the Department of the Environment in a manner consistent with the Toxic Substances Export Notification Regulations;

·has notified the Minister in writing, of his intent to manufacture the substance, 60 days prior to the starting date of the manufacturing process; and

·uses a fully contained process for manufacturing the substance.

These Regulations will not apply to the use, manufacture, processing, sale, offering for sale or import for uses of the substance covered under the Pest Control Product Act.

The reasons for the final regulatory action were relevant to: Environment

Summary of known hazards and risks to the environment:

This substance may persist in the environment as degradation was not observed in biotic degradation tests and significant hydrolysis and photolysis did not occur under environmentally relevant conditions. The log of the octanol/water partition coefficient (log K_ow) for the substance is 2.45, indicating the substance has limited potential to bioaccumulate in organisms.

The substance has been determined to be toxic under CEPA as it may enter the environment in quantity or concentration or under conditions that may have an immediate or long-term effect on the environment.

Expected effect of the final regulatory action in relation to the environment:
