Rate of Deposition. The amount of sulphur and nitrogen compounds and other substances deposited to ground level per unit of time.
Real-time Access. An operation or other response in which programmed responses to an event are essentially simultaneous with the event itself. Pertaining to data-processing system that controls an ongoing process and delivers its outputs (or controls its inputs) not later than the time when these are needed for effective control.
Recirculated Sinter Return Bin. The Sintering process of a smelter, which fuses iron ore fines into hard clinkers suitable for use in a blast furnace. The sinter returns bin captures and recirculates the fines not used in the fusion of the hard clinker.
Reclaim. With respect to ozone depleting substances, to reprocess the substance by means of distillation, filtration, drying or other means so that it meets the specifications for such a substance when new and unused and to verify that it meets the specifications by means of chemical analysis.
Reclaim Area. An area where materials from mining are recovered for the purpose of reprocessing or reuse.
Reclamation. The restoration of materials found in a waste stream that are of a beneficial use, perhaps other than the original use.
Recover. With respect to an ozone depleting substance, to remove the substance in any condition from equipment and store it in a container that is separate from the equipment, whether or not the substance is cleaned, tested or reprocessed after removal.
Recovery Boiler Scrubber & Precipitator. A recovery boiler is a unit used to burn recovered cooking liquor to produce steam and to reprocess inorganic cooking chemicals. In the combustion phase of the boiler, air contaminants are generated such as particulate matter and total reduced sulphur. The precipitator is an air pollution control device used to collect the particulate matter generated, and the scrubber is used to remove the remaining particulate and sometimes the total reduced sulphur compounds before the air waste stream is released to the atmosphere.
Recycle. With respect to ozone depleting substances, to purify the substance after recovery so that it may be reused and to restore it to equipment for reuse.
Refined Lead. Lead that is treated to reduce impurities.
Refinery. An industrial facility in which refined petroleum products such as gasoline and diesel are produced on a commercial scale from crude petroleum, natural gas or other hydrocarbon sources.
Refinery Fuel. A blend of petroleum hydrocarbons burned as fuel within the refinery. It is a combination of fuel oil, refinery fuel gas and liquefied petroleum gas. It also means sour gas, which has been stripped of the majority of its sulphur bearing compounds.
Reforming Operations. Operations specific to an oil refinery that change or reform the structure of hydrocarbon molecules. These changes allow the molecules to be refined into feedstock products more easily.
Register. A register maintained by the Minister under subsection 12(1) of the Clean Air Act.
Registration. Is a registration under the Clean Air Act or subsequent regulations that has not expired or been suspended or cancelled.
Reinjection Systems. See Ash Reinjection System.
Repealed. With respect to specific regulations, means they have been annulled and no longer exist.
Resin. Any of a class of solid or semi-solid organic products of natural or synthetic origin with no definite melting point. They generally have a high molecular weight, a softening or melting range and are generally polymers. Resins are typically used in the manufacture of composite materials such as fibreglass insulation materials, particleboard, and plywood.
Retention Time. A design parameter for various air pollution control devices or water treatment and is the time at which the contaminant is retained in contact with an absorbing or filtering media used to collect the contaminant, or combustion chamber to incinerate the contaminant. Generally, the longer the retention time the greater the efficiency of the contaminant being removed or oxidized.
Retorting. In the mining industry, a process by which low boiling point metals are separated from the metal bearing mineral using high temperatures. The temperatures in a retorting furnace can be from external sources or from electrothermic sources.
Revoked Orders. When used under section 12 (3) of the Clean Air Act means an order has been withdrawn or cancelled.
Right to Information Act. Entitles any person to request and receive information relating to the public business of the Province, including any activity or function carried on, or performed by any Department to which the Act applies. Requests can be made by applying to the Minister of the Department where the information is likely to be kept or filed. The appropriate Minister may then grant or deny the request in writing and within 30 days of receipt.
Rolling average. A arithmetic average of a specified number of contiguous periods. For example, a 30 day rolling average, would mean that the average of the consecutive daily emission rates, are determined for the preceding 30 days of facility operation.
Rotary Kiln. A unit with an inclined rotating drum that has a direct fired flame and is used to dry process stream and produce chemical reactions that alter the chemical composition of process streams. Used largely in the asphalt paving, petroleum contaminated soil, fish meal, and limestone processing to drive off moisture.
Rotating Biological Contactor (RBC). A air or water pollution control device that uses a scrubbing media comprised of microorganisms on a rotating disc. The microbials oxidize the organic contaminants of the air or water waste stream and therefore reduce the organic contaminants being released to the environment. This type of device is generally used for odour control purposes.
