Marginal note:Definitions

1 The following definitions apply in these Regulations.

Act

Act means the Fisheries Act. (Loi)

acutely lethal

acutely lethal, in relation to effluent, means that the effluent at 100% concentration kills, during a 96-hour period, more than 50% of the rainbow trout subjected to it. (létalité aiguë)

aquatic species

aquatic species includes an aquatic species as defined in subsection 2(1) of the Species at Risk Act. (espèce aquatique)

authorization officer

authorization officer, in respect of a province set out in column 1 of Schedule 1 and for each type of owner set out in column 2 of a wastewater system located in the province, means the holder of the position set out in column 3. (agent d’autorisation)

blackwater

blackwater means used water from sanitary appliances that contains human fecal matter or human urine. (eaux-vannes)

carbonaceous biochemical oxygen demanding matter

carbonaceous biochemical oxygen demanding matter or CBOD matter means carbonaceous matter that consumes, by biochemical oxidation, oxygen dissolved in water. (matières exerçant une demande biochimique en oxygène de la partie carbonée ou matière exerçant une DBOC)

combined sewer

combined sewer means a sewer that is designed to collect surface runoff and stormwater in such a manner that it mixes with wastewater referred to in any of paragraphs (a) to (c) of the definition wastewater or any combination of wastewater referred to in those paragraphs. (égout unitaire)

effluent

effluent means wastewater that is deposited from a wastewater system. (effluent)

final discharge point

final discharge point means the point, other than an overflow point, of a wastewater system beyond which its owner or operator no longer exercises control over the quality of the wastewater before it is deposited as effluent in water or a place. (point de rejet final)

greywater

greywater means used water, other than blackwater, from sanitary appliances or from other appliances in a kitchen or laundry. (eaux grises)

hydraulic retention time

hydraulic retention time, in relation to a wastewater system, means the average period during which wastewater is retained for treatment within the wastewater system. (temps de rétention hydraulique)

influent

influent means wastewater entering a wastewater system. (affluent)

overflow point

overflow point means a point of a wastewater system via which excess wastewater may be deposited in water or a place and beyond which its owner or operator no longer exercises control over the quality of wastewater before it is deposited as effluent. (point de débordement)

point of entry

point of entry, in relation to the final discharge point or an overflow point of a wastewater system, means

• (a) the point where effluent is deposited in water frequented by fish via the final discharge point or the overflow point, as the case may be; or

• (b) any point where the effluent enters that water from the place where it was deposited via the final discharge point or the overflow point, as the case may be. (point d’entrée)

previous calendar year

previous calendar year, in respect of a given period and a wastewater system, means the most recent calendar year during which effluent was deposited via the system’s final discharge point that ended before the given period. (année civile précédente)

previous month

previous month, in respect of a given period and a wastewater system, means the most recent month during which effluent was deposited via the system’s final discharge point that ended before the given period. (mois précédent)

previous quarter

previous quarter, in respect of a given period and a wastewater system, means the most recent quarter during which effluent was deposited via the system’s final discharge point that ended before the given period. (trimestre précédent)

Procedure for pH Stabilization EPS 1/RM/50

Procedure for pH Stabilization EPS 1/RM/50 means the Procedure for pH Stabilization During the Testing of Acute Lethality of Wastewater Effluent to Rainbow Trout (EPS 1/RM/50), March 2008, published by the Department of the Environment, as amended from time to time. (Procédure de stabilisation du pH SPE 1/RM/50)

protected species

protected species means a wildlife species as defined in subsection 2(1) of the Species at Risk Act that is

• (a) a species at risk as defined in subsection 2(1) of that Act or is a species that is listed in Schedule 1 to that Act; or

• (b) a species that is protected, or classified as an endangered species or a threatened species as defined in subsection 2(1) of that Act, under the laws of a province. (espèce protegée)

quarter

quarter, in respect of a year, means any of the four periods of three months that begin on the first day of January, April, July and October. (trimestre)

Reference Method EPS 1/RM/13

Reference Method EPS 1/RM/13 means the Biological Test Method: Reference Method for Determining Acute Lethality of Effluents to Rainbow Trout (EPS 1/RM/13 Second Edition), December 2000 with May 2007 amendments, published by the Department of the Environment, as amended from time to time. (Méthode de Référence SPE 1/RM/13)

sanitary sewer

sanitary sewer means a sewer that is designed to collect wastewater referred to in any of paragraphs (a) to (c) of the definition wastewater or any combination of wastewater referred to in those paragraphs. (égout sanitaire)

suspended solids

suspended solids means any solid matter contained in effluent that is retained on a filter of 2.0 micrometre (μm) or smaller pore size. (matières en suspension)

total residual chlorine

total residual chlorine means the sum of free chlorine and combined chlorine, including inorganic chloramines. (chlore résiduel total)

wastewater

wastewater means

• (a) blackwater;

• (b) greywater that is mixed with blackwater;

• (c) used water — other than blackwater and greywater — from an industrial, commercial or institutional facility that is mixed with blackwater; or

• (d) surface runoff and stormwater that is mixed with blackwater. (eaux usées)

wastewater system

wastewater system means any work or undertaking, at least part of which is located on land, that is used for the collection and deposit of wastewater, whether or not the wastewater is treated, and includes a site that contains a wastewater lagoon. (système d’assainissement)
