“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)
