WATER SHARING PLAN FOR THE GREATER METROPOLITAN REGION UNREGULATED RIVER WATER SOURCES 2011 - SCHEDULE 1
SCHEDULE 1 – Dictionary
"Aboriginal person" has the same meaning as it has in the
Aboriginal Land Rights Act 1983 .
"alluvial sediments" means unconsolidated fluvio-lacustrine sediments.
"approved EP&A Act development" means:
(a) a project approved under Part 3A of the Environmental Planning and Assessment Act 1979 (whether before or after its repeal), or
(b) State significant development authorised by a development consent under Part 4 of that Act, or
(c) State significant infrastructure approved under Part 5.1 of that Act.
"black start" means the provision of electricity to the national grid by Eraring Energy in order to restore operation of the electricity system in the event of a partial or complete shutdown of coal-fired power stations, and the subsequent power outages.
"dead storage" means the portion of a water storage capacity that is equal to the volume of water below the level of the lowest outlet (the minimum supply level). This water cannot be accessed under normal operating conditions.
"divert" means the transfer of water by artificial means from one storage to another by a route which differs from the route the water otherwise would have taken.
"fractured rock" means sedimentary, igneous and metamorphic rocks with fractures, joints, bedding planes and cavities in the rock mass that are capable of transmitting water.
"full containment volume" means the volume of water that is impounded in the pool, lagoon or lake when the level of water in the pool, lagoon or lake is at the high water mark.
"Full Supply Level" means the normal maximum operating water level of a water storage when not affected by floods. This water level usually corresponds to the spillway water level or 100% capacity.
"grazeable area" means, for an individual landholding, the area of pasture in hectares for a pasture type that is accessible for stock grazing and able to grow appropriate vegetation for stock grazing, but does not include impervious surfaces (such as rocks or rocky terrain, man-made structures, mines or quarries) or other such surfaces that do not support grazing vegetation such as water bodies and forested floors with no undergrowth.
"individual daily extraction limit" (
"IDEL" ) is the volume of water that may be extracted by an individual access licence from an unregulated river on a daily basis from a particular flow class.
"in-river dam" means a dam located in a river.
"in-river dam pool" means the area of water immediately upstream of an in-river dam where the river has pooled as a result of an in-river dam.
"in-river pool" means a natural pool, lagoon or lake that is within a river or stream (regardless of stream size) and excludes:
(a) a pool that is on a flood-runner or floodplain, or
(b) a pool that is on an effluent that only commences to flow during high flows.
"interchange" means the movement of water from one storage to another, and the return of that water to the original storage by Eraring Energy.
"lentic water body" means a water source, such as a swamp, bog or marsh where water levels do not experience a corresponding decrease when nearby river water levels decrease.
"Logbook" , in relation to an access licence or water supply work approval, means a written record, kept in hard copy or electronic form, which accurately records all information required to be kept in relation to the access licence or water supply work approval under the rules of this Plan.
"management zone" is an area within a water source in which rules particular to that management zone will apply, for example daily extraction limits and restrictions on dealings.
"mangrove limit" is as defined in the DIPNR Survey of tidal limits and mangrove limits in NSW estuaries 1996 to 2003 (NSW Dept of Commerce, Manly Hydraulics Laboratory).
"off-river pool" means a natural pool, lagoon or lake that is:
(a) not within a river or stream (regardless of stream size), or
(b) located on a flood-runner or floodplain, or
(c) located on an effluent that only commences to flow during high flows.
"Plan Map" for these water sources has the same meaning as in clause 4 (2) of this Plan.
"porous rock" means consolidated sedimentary rock containing voids, pores or other openings (such as joints, cleats and/or fractures) which are interconnected, in the rock mass and are capable of transmitting water.
"runoff harvesting dam" means a dam on a hillside or minor stream which collects and stores rainfall runoff. Minor streams are defined in harvestable rights orders made under section 54 of the Act. For the purposes of this Plan, references to runoff harvesting dams as water supply works include any associated pumps or other works which take water from the dam. For the purpose of clarity, this definition includes dams that are also used to store water diverted into the dam from a river or other source of water.
"shepherding" means the delivery of a calculated volume of water that was created by non-activation/reduced extraction at a nominated licence location to a more downstream location, after consideration of losses, where it will be made available for extraction or use for the environment.
"signal stage" is the stage of the weir necessary to deliver a required environmental release over a 24-hour period.
"stage of the weir" means the current recorded operating level of the reservoir behind the weir.
"total active storage" means the total volume of water in the water storage minus the volume of dead storage.
"total daily extraction limit" (
"TDEL" ) is the volume of water that may be extracted under access licences from an unregulated river on a daily basis from a particular flow class.
"total storage capacity" means the entire volume of water contained by the water storage at Full Supply Level; equal to the sum of the active storage capacity plus the dead storage capacity.
"transmission losses" are any loss of water volume, through natural influences such as evaporation or seepage, which occurs as water travels down a river.
"visible flow" means continuous downstream movement of water that is perceptible to the eye.
"Water Act 1912 entitlement" has the same meaning as an entitlement has in clause 2 of Schedule 10 to the Act.
"water storage" means the water body impounded by a dam, weir or other structure, which is used to regulate and manage river flows in this water source.
"wild river" means any river or part of a river that has been declared to be a wild river by notification published in the NSW Government Gazette under section 61 of the National Parks and Wildlife Act 1974 .
