Chromium Electroplating, Chromium Anodizing and Reverse Etching Regulations (SOR/2009-162)

1 The following definitions apply in these Regulations.

Act

Act means the Canadian Environmental Protection Act, 1999. (Loi)

chromium anodizing

chromium anodizing means the passage of an electric current through a solution containing a hexavalent chromium compound, in a tank connected to a rectifier, in order to produce an oxide layer on the surface of a metal or other substrate. (anodisation au chrome)

chromium electroplating

chromium electroplating means the passage of an electric current through a solution containing a hexavalent chromium compound, in a tank connected to a rectifier, in order to produce a layer of chromium on the surface of a metal or other substrate. (électrodéposition du chrome)

control device

control device means equipment used to control emissions of hexavalent chromium compounds produced from or during chromium electroplating, chromium anodizing or reverse etching. (dispositif de contrôle)

dilution air

dilution air means air that is introduced into emissions produced from or during chromium electroplating, chromium anodizing or reverse etching and that dilutes those emissions. (air de dilution)

dscm

dscm means a dry standard cubic metre of sample gas referenced to 25°C and 101.325 kPa. (dscm)

evacuation device

evacuation device means equipment that is attached to a tank cover that contains a HEPA filter and that is used to remove any hexavalent chromium compounds remaining in the volume of air beneath the closed tank cover at the completion of chromium electroplating, chromium anodizing or reverse etching and before the tank cover is opened. (dispositif d’évacuation)

facility

facility means a place at which chromium electroplating, chromium anodizing or reverse etching is performed. (installation)

HEPA filter

HEPA filter means a high-efficiency particulate air filter. (filtre HEPA)

hexavalent chromium

hexavalent chromium means chromium in an oxidation state of +6. (chrome hexavalent)

point source

point source means a stack or vent that is the outlet to the environment from the emission collection system connected to one or more tanks. (source ponctuelle)

representative operating conditions

representative operating conditions means the conditions for obtaining an electrical output from a tank’s rectifier while chromium electroplating, chromium anodizing or reverse etching is taking place that is equal to the average of the rectifier’s output for the 30 days of use before a release test is performed. (conditions d’exploitation représentatives)

reverse etching

reverse etching means the passage of an electric current through a solution containing a hexavalent chromium compound, in a tank connected to a rectifier, in order to produce an etch on a metal or other substrate. (gravure inversée)

surface tension

surface tension means the molecular force, measured in dynes per centimetre (dyn/cm), that exists at the interface between the solution containing a hexavalent chromium compound and the air. (tension superficielle)

tank

tank means the container in which chromium electroplating, chromium anodizing or reverse etching is carried out. (cuve)

total chromium

total chromium means the sum of hexavalent chromium and all other species of chromium. (chrome total)
