Notice with respect to certain perfluoroalkyl and fluoroalkyl substances. Pursuant to paragraph 71(1)(b) of the Canadian Environmental Protection Act, 1999, notice is hereby given that the Minister of the Environment requires, for the purpose of assessing whether the substances listed in Schedule 1 to this notice are toxic or are capable of becoming toxic, or for the purpose of assessing whether to control or the manner in which to control the listed substances, any person described in Schedule 2 to this notice who possesses or who may reasonably be expected to have access to the information required in Schedule 3 to this notice to provide that information no later than April 28, 2005, at 3 p.m. Eastern Standard Time.

SCHEDULE 1 Substances
The substances included in the scope of this notice are those that meet the following criteria: Perfluoroalkyl and fluoroalkyl substances that contain the chemical fragment R-(CF2)n-R', where n is greater than or equal to 3, R is any atom or molecular moiety, R' is any atom or molecular moiety other than H, F or Cl, and any F may be substituted with a perfluoroalkyl group. (Excluding perfluorooctane sulfonate (PFOS), its salts, and its precursors that contain the C8F17SO2, C8F17SO3, or C8F17SO2N group.)

Poly(difluoromethylene), alpha-chloro-omega(2,2-dichloro-1,1,2-trifluoroethyl)- was included in the following list:

US EPA List of Inerts. This substance is on List 3.

Note: US EPA allows so-called "Inert" ingredients to be commonly mixed with the "active" pesticidal ingredient to create a formulated pesticide product. According to EPA, "The term `inert' is not intended to imply nontoxicity; the ingredient may or may not be chemically active." "Inert" ingredients include solvents, emulsifiers, spreaders, and other substances mixed into pesticide products to increase the effectiveness of the active ingredients, make the product easier to apply, or to allow several active ingredients to mix in one solution. Both US EPA and California Department of Pesticide Regulation require pesticide manufacturers to identify inert ingredients in their products but do not disclose this information to the general public because the pesticide industry considers product formulations trade secrets, protected by law and by the US EPA. The US EPA category of Inerts (as of September 2003):

List 1 - Of Toxicological Concern
List 2 - Potentially Toxic / High Priority for Testing
List 3 - Of Unknown Toxicity
List 4A - Generally Regarded as Safe
List 4B - EPA states it has Sufficient Information to Reasonably Conclude that the Current Use Pattern in Pesticide Products will not Adversely Affect Public Health or the Environment
List 4 (all)
