Obstruction means any circumstance relating to the whole or any part of the Infrastructure, including Rollingstock, debris or other objects on the Infrastructure, which has the potential to cause a disruption to or cancellation of Train Services or Train Movements, and includes any Network Incident but does not include an Operational Constraint imposed by Aurizon Network.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Incineration means an engineered process involving burning or combustion of solid waste to thermally degrade waste materials at high temperatures;
Sedimentation means a process for removal of solids before filtration by gravity or separation.
Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.
Slug loading means any pollutant, including oxygen demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration as to cause interference in the POTW.
Incinerator means any enclosed device that:
Drainage system means one or more artificial ditches, tile drains or similar devices which collect surface runoff or groundwater and convey it to a point of discharge.
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Underground source of drinking water means an aquifer or its portion:
Curbside “Curb” means that portion of the right-of-way adjacent to paved or traveled roadways, including the end of a driveway, curb line or alley line. Containers will be placed as close to the roadway as practicable without interfering with or endangering the movement of vehicles or pedestrians.
Pedestrian means any person afoot.
Drainage area means a geographic area within which stormwater, sediments, or dissolved materials drain to a particular receiving waterbody or to a particular point along a receiving waterbody.
Engine under the Lease. The term "Engines" means, as of any date of determination, both Engines then leased to the Lessee pursuant to the Lease.
Drainage means the removal of surface water or groundwater
Ambient air means that portion of the atmosphere, external to buildings, to which the general public has access.
Stormwater management planning area means the geographic area for which a stormwater management planning agency is authorized to prepare stormwater management plans, or a specific portion of that area identified in a stormwater management plan prepared by that agency.
Slow sand filtration means a process involving passage of raw water through a bed of sand at low velocity (generally less than 0.4 meters per hour) resulting in substantial particulate removal by physical and biological mechanisms.
Cabin means a non-residential enclosure constructed of non-load bearing partitions;
Enclosure means the part enclosing the internal units and providing protection against any direct contact.
Snowmobile means a self-propelled vehicle designed to travel on snow or ice, steered by skis or
Standard Methods for the Examination of Water and Wastewater means the most recent edition of Standard Methods for the Examination of Water and Wastewater published jointly by the American Public Health Association, the American Waterworks Association and the Water Environment Federation;
Floodproofing means any combination of structural and nonstructural additions, changes, or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitation facilities, structures, and their contents.
Filtration means a process for removing particulate matter from water by passage through porous media.
Boiler means an enclosed fossil or other fuel-fired combustion device used to produce heat and to transfer heat to recirculating water, steam, or other medium.
Explosives or munitions emergency response specialist means an individual trained in chemical or conventional munitions or explosives handling, transportation, render-safe procedures, or destruction techniques. Explosives or munitions emergency response specialists include Department of Defense (DOD) emergency explosive ordnance disposal (EOD), technical escort unit (TEU), and DOD-certified civilian or contractor personnel; and other Federal, State, or local government, or civilian personnel similarly trained in explosives or munitions emergency responses.
