“daily loss” means the measurement of TSS, BOD5 or AOX discharge expressed in kilograms per day, corresponding
(1)  for the final effluent discharged into the environment or into a storm sewer, to the concentration of the contaminant in that effluent multiplied by the daily flow of that effluent;
(2)  for the final effluent discharged into a sewer system, to the result obtained using the following formula: A x B x C, where A is the concentration of the contaminant in that effluent, B is the daily flow of that effluent and C is the portion of those contaminants not eliminated by municipal treatment, being 15% for TSS and BOD5 and 50% for AOX; (perte quotidienne)
“daily production of finished product” means the quantity of finished product manufactured each day and intended for sale and, in the case of a complex, the quantity of finished product manufactured each day and intended for sale outside the complex; that quantity is expressed in tons and determined by weight; if the water content of the finished product is greater than 10%, the quantity weighed is corrected to bring the water content back to 10%; (production quotidienne de produits finis)
“day” means a 24-hour interval commencing at a fixed time and corresponding to both the period during which the necessary sampling is performed to collect the composite samples in Chapter IV and the period during which daily production of finished product is calculated; (jour)
“dissolving grade sulphite pulp” means purified pulp produced by the sulphite process, with a cooking yield of less than 46% at all times; the cooking yield corresponds to the number of kilograms of oven-dry pulp produced from 100 kg of oven-dry wood; (pâte au bisulfite à dissoudre)
“effluent” means process water that is no longer treated before being discharged into the environment, into a storm sewer or into a sewer system; (effluent)
“final effluent” means the effluent discharged into the environment, into a storm sewer or into a sewer system; (effluent final)
“finished product” means the paper product or pulp; (produit fini)
“leachate” means liquid or filtrate that has percolated through a layer of residual materials; (eaux de lixiviation)
“maximum lethality level” means the level where effluent toxicity causes the death of 50% of rainbow trout exposed for 96 hours to an effluent diluted in a ratio of 1:3 by volume; in such a case, toxicity is equal to 3 toxic units; (niveau maximum de létalité)
“mill” means any plant designed or used to manufacture a paper product or pulp intended for sale; (fabrique)
“mill residual materials” means bark, wood residue, pulp, paper and paperboard discards, ash from a combustion facility, sludge from process water treatment, de-inking sludge, lime sludge, green liquor dregs, residues from lime slaking and any other residue from the pulp or paper product manufacturing process that is not a hazardous material within the meaning of section 1 of the Environment Quality Act (chapter Q-2); (matières résiduelles de fabrique)
“mixed sludge” means a mixture of sludge from process water treatment or a mixture of sludge from process water treatment and de-inking sludge; (boues mixtes)
“monthly loss” means the sum of the total daily losses for a final effluent measured over 1 month, divided by the number of days in the month on which sampling and analysis were conducted, the result of which is multiplied by the number of days in the month on which there was a discharge; for AOX, the result is multiplied by the number of days in the month in which bleached pulp was produced on which there was discharge into the environment; (perte mensuelle)
“paper product” means a product directly derived from pulp, such as paper, paperboard and any absorbent product or construction material manufactured on a paper or board machine; (produit de papier)
“particles” means any substance, except uncombined water, which exists in a finely divided liquid or solid state in suspension in a gaseous environment; (particules)
“ppm” means parts per million by volume; (ppm)
“process water” means wastewater from the operation of a mill, such as water from the treatment of feed water, water from the various stages of production, wash water or washing solutions that may be treated by the mill, boiler blow-down water, cooling water and seal water; (eaux de procédé)
“pulp” means treated cellulose fibres that are derived from wood, another vegetable material or recycled paper products; (pâte)
“reference conditions” means a temperature of 25 °C and a barometric pressure of 101.3 kPa; (conditions de référence);
“RPRB” means the reference production rate for bleached pulp with a chlorinated bleaching agent and, where applicable, the interim reference production rate for bleached pulp with a chlorinated bleaching agent; in the case of a complex, the reference production rate excludes the production of bleached pulp from a mill whose construction was completed after 21 October 1992; (RPRB)
“RPRD” means the reference production rate for dissolving grade sulphite pulp and, where applicable, the interim reference production rate for dissolving grade sulphite pulp; (RPRD)
“RPRF” means the reference production rate for all finished product other than dissolving grade sulphite pulp and, where applicable, the interim reference production rate for finished product other than dissolving grade sulphite pulp; in the case of a complex, the reference production rate excludes the production of finished product intended for sale or use within the complex and from a mill whose construction was completed after 21 October 1992; (RPRF)
“RPRNB” means the reference production rate for pulp bleached with a chlorinated bleaching agent from a mill whose construction was completed after 21 October 1992 and that is part of an existing complex and, where applicable, the interim reference production rate for pulp bleached with a chlorinated bleaching agent from a mill whose construction was completed after 21 October 1992 and that is part of an existing complex; (RPRNB)
“RPRNF” means the reference production rate for finished product from a mill whose construction was completed after 21 October 1992 and that is part of an existing complex and, where applicable, the interim reference production rate for finished product from a mill whose construction was completed after 21 October 1992 and that is part of an existing complex; (RPRNF)
“sanitary wastewater” means wastewater from a mill’s sanitary facilities; (eaux domestiques)
“sewer system” means a municipal system of separate or combined sewers, excluding storm sewers; (réseau d’égouts)

“total monthly loss” means the sum of the monthly losses for each of the final effluents; (perte mensuelle totale)
“TSS” means total suspended solids; (MES)
“100-year flood line” means the line that corresponds to the limit line of a flood likely to occur once every 100 years. (ligne d’inondation de récurrence de 100 ans)
An operator includes the person who has custody of a mill or a complex, a process water purification plant that is not a municipal plant, or a facility for the storage, final deposit by landfilling or treatment by combustion of mill residual materials.
