Part 3 Basis for water sharing
14   Basis for water sharing
This Part is made in order to give effect to section 5 (3) of the Act, and in accordance with sections 20 (2) (c) and 21 (e) of the Act.
15   Climatic variability
(1)  This Plan recognises climatic variability and therefore river flow variability in this water source, and also that the level of natural recharge to the groundwater component of this water source will vary.
(2)  To give effect to subclause (1), this Plan has provisions that manage:
(a)  the sharing of groundwater in this water source within the limits of groundwater availability on a long-term average basis,
(b)  sharing of the flows that occur in this water source on a daily basis, and
(c)  water extraction to enable the protection of groundwater dependent ecosystems, aquifer integrity and water quality of this water source.
16   Extraction management unit
(1)  The availability of water for extraction from this water source on a long-term average basis will be determined at the level of an extraction management unit.
(2)  The extraction management unit of which this water source is part is known as the Goulburn Extraction Management Unit (hereafter this Unit), and is shown on the map in Schedule 5.
(3)  This Unit excludes all groundwater sources unless the groundwater source is established by a Plan made under sections 41 or 50 of the Act to be within this Unit.
(4)  This Unit excludes any river declared by the Minister, and published in the NSW Government Gazette, to be a regulated river.
17   Flow classes
This Plan establishes the following flow classes as the basis for sharing access to water on a daily basis:
(a)  very low flow class at or less than 1 megalitre per day (hereafter ML/day) on a rising river, and at or less than 0.5 ML/day on a falling river,
Note—
0.5 ML/day corresponds to the estimated 90th percentile of all days with flow, and is referred to as the cease to pump on a falling river, and 1 ML/day corresponds to the estimated 80th percentile of all days with flow, and is referred to as the commence to pump on a rising river. Special provisions may result in a review of the cease to pump during the life of this Plan.
(b)  B class flows greater than 1 ML/day and at or less than 7 ML/day on a rising river, and greater than 0.5 ML/day and at or less than 7 ML/day on a falling river,
(c)  C class flows greater than 7 ML/day and at or less than 16 ML/day,
(d)  D class flows greater than 16 ML/day and at or less than 100 ML/day, and
(e)  E class flows greater than 100 ML/day.
Note—
This Plan provides for a review of the very low flow class in accordance with clauses 76 and 77.
Note—
The flow classes have been determined based on flow information that inherently includes seasonal effects as well as evaporation and seepage losses.
18   Flow reference point
For the purpose of this Plan, all flows referred to relate to the estimated flows at the flow reference point at the downstream end of this water source, as shown on the map in Schedule 2.
19   Determination of flow class
Announcement of flow classes will be made from time to time by the Minister based on the flow at a flow gauging station, correlated to the flow reference point established in clause 18.
Note—
At the commencement of this Plan, the Wybong flow gauging station will be used as the tool to assess the end of water source flow. Additional flow gauging stations may be established as part of the implementation of this Plan. All gauging stations will be calibrated to the flow reference point.
20   Recharge of the groundwater component of this water source
For the purposes of section 5 (3) of the Act, the overall basis for water sharing in this Plan includes the average annual recharge to the alluvial aquifers in this water source of 3,820 megalitres per year (hereafter ML/yr).
Part 4 Environmental water provisions
21   Environmental water provisions
This Part is made in accordance with sections 5 (3) and 8 (1), 8 (2) and 20 (1) (a) of the Act.
22   Planned environmental water
(1)  Environmental health water is identified and established as follows:
(a)  in very low flows, the surface water flow occurring in this water source, minus the very low flow access permitted under clause 66A of this plan, plus the groundwater storage component of this water source, plus 100% of the groundwater recharge, minus 1.8 ML/day,
Note—
1.8 ML/day is the amount of water estimated at the commencement of the Plan for basic landholder rights. At the time of making this Plan there were no access licences with very low flow access.
(b)  in B class flows, the surface water flow occurring in this water source, plus the groundwater storage component of this water source, plus 50% of the groundwater recharge, minus 8.8 ML/day,
Note—
8.8 ML/day is the amount of water estimated at the commencement of the Plan for B class total daily extraction limits and basic landholder rights.
(c)  in C class flows, the surface water flow occurring in this water source, plus the groundwater storage component of this water source, plus 30% of the groundwater recharge, minus 15.3 ML/day,
Note—
15.3 ML/day is the amount of water estimated at the commencement of the Plan for C class total daily extraction limits and basic landholder rights.
(d)  in D class flows, the surface water flow occurring in this water source, plus the groundwater storage component of this water source, plus 30% of the groundwater recharge, minus 21.8 ML/day,
Note—
21.8 ML/day is the amount of water estimated at the commencement of the Plan for D class total daily extraction limits and basic landholder rights.
(e)  in E class flows, the surface water flow occurring in this water source, plus the groundwater storage component of this water source, plus 30% of the groundwater recharge, minus 38.8 ML/day, and
Note—
38.8 ML/day is the amount of water estimated at the commencement of the Plan for E class total daily extraction limits and basic landholder rights.
(f)  on a rising river, the daily flow for 24 hours after an upper flow level specified in clause 17 (a) to (c) is exceeded, minus the total daily extraction limit (hereafter TDEL) for the flow class that occurred prior to the flow level being exceeded as specified in clause 46 (1), minus the provision for basic landholder rights specified in clauses 27 and 28.
Note—
This provision ensures the first flush of a rising river is allowed to pass before increased water extraction can commence.
(2)  The planned environmental water in subclause (1) may be amended, as specified in clause 76.
(3)  Environmental health water is maintained as follows:
(a)  in very low flows:
(i)  the holders of access licences, except for those listed in Schedule 6, are not permitted to access any water,
(ii)  access licences listed in Schedule 6 have restricted access to water as specified in clause 66A, and
(iii)  persons excercising domestic and stock and native title rights may take a combined total of up to 1.8 ML/day,
Note—
The Minister may issue an Order under section 328 of the Act to restrict the exercise of domestic and stock rights from this water source to protect the environment, for reasons of public health, or to preserve basic landholder rights.
(b)  in B class, C class, D class and E class flows:
(i)  the holders of access licences have restricted access to water as specified in clause 46,
(ii)  persons exercising domestic and stock and native title rights may take water, and
(iii)  if the water taken under domestic and stock and native title rights is assessed to be exceeding 1.8 ML/day in this flow class the access to water for access licences will be reduced in accordance with clause 51 to maintain the planned environmental water in this flow class,
(c)  in all flow classes, limits are imposed on the availability of water in accordance with clauses 36 and 38, that protect a proportion of both natural river flows and the average annual recharge of the aquifer for fundamental ecological needs from increases in long-term water extraction,
(d)  on a rising river, for 24 hours after an upper flow level specified in clause 17 (a) to (c) is exceeded, the holders of access licences may only extract the TDEL for the flow class that occurred prior to the flow level being exceeded as specified in clause 46 (1),
(e)    (Repealed)
(f)  the Minister may:
(i)  within twelve months of gazettal of this Plan, identify pools in the rivers in the water source that require special protection and establish initial pool control levels at key sites,
(ii)  consult with appropriate Government Departments and water users in the water source in establishing the control levels in subclause (i),
(iii)  determine that, notwithstanding all other rights and conditions, extraction of water from a designated pool is not permitted below a specified level, and
(iv)  pursuant to section 45 (1) (b) of the Act, review the initial pool control levels in accordance with clause 76.
Note—
These rules protect the water for the environment by limiting both the water extracted over the long term, and the rate of extraction of water in different flow ranges, and by limiting extraction from the alluvial aquifer to a percentage of the annual average recharge, thereby achieving the objectives of this Plan.
Note—
This Plan recognises that the planned environmental water provisions provide non-extractive benefits including, traditional Aboriginal spiritual, social, customary and cultural benefits, and contribute to improved water quality.
cll 22: Am 1.7.2004.
23   Extraction by water supply work
(1)  Notwithstanding all other rights and conditions, extraction of water from a river by an approved water supply work is permitted only if there is visible flow in the river in the vicinity of the work.
(2)  In addition to subclause (1), all approved water supply works within 40 metres of the rivers specified in Schedule 3, shall comply with pool control levels and key sites established under clause 22 (3) (f).
Note—
Provisions in this clause will help achieve the objective specified in clause 11 (a).
cll 23: Am 1.7.2004.
24   Planned environmental water
At the commencement of this Plan, there is no water committed for specified environmental purposes in accordance with section 8 (1) (b) of the Act.
25   Adaptive environmental water
(1)  At any time an access licence holder may, by a process determined by the Minister, commit all or part of their licence as adaptive environmental water.
(2)  The Minister may grant an access licence in a water source to which this Plan applies if the licence is subject to an adaptive environmental water condition and arises through water savings in the system made in that water source as referred to in section 8C (1) of the Act.
(2A)  The Minister may change the category or subcategory of an access licence in a water source to which this Plan applies if the licence is subject to an adaptive environmental water condition that arises through water savings as referred to in section 8D of the Act.
(3)  At the commencement of this Plan there are no access licences committed to an environmental purpose in accordance with section 8 (1) (c) of the Act.

Part 5 Basic landholder rights
26   Basic landholder rights
This Part is made in accordance with sections 5 (3) and 20 (1) (b) of the Act.
Note—
The Minister may issue an Order under section 328 of the Act to restrict the exercise of domestic and stock and native title rights from this water source to protect the environment, for reasons of public health, or to preserve basic landholder rights.
27   Domestic and stock rights
(1)  At the commencement of this Plan, the water requirements of holders of domestic and stock rights are estimated to be a total of 1.8 ML/day.
(2)  This Plan recognises that the exercise of domestic and stock rights may increase during the term of this Plan.
Note—
Increase in use of domestic and stock rights may occur as a result of an increase in the number of landholdings fronting rivers and lakes in this water source or as a result of an increase of the exercise of basic landholder rights by existing landholders and/or by the subdivision of properties where water can be extracted from the alluvial aquifer.
28   Native title rights
(1)  At the commencement of this Plan there are no holders of native title rights and therefore the water requirements for native title rights are a total of 0 ML/day.
(2)  This Plan recognises that the exercise of native title rights may increase during the term of this Plan.
Note—
Increase in use of native title rights may occur as a result of granting of native title rights under the Commonwealth’s Native Title Act 1993.
29   Harvestable rights
The requirement for water under harvestable rights is the amount of water owners of land are entitled to capture pursuant to the harvestable rights Order published in the NSW Government Gazette on 23 March 2001 under section 54 of the Act.
Part 6 Bulk access regime
30   Bulk access regime
(1)  This Part is made in accordance with section 20 (1) (e) of the Act.

This Division is made in accordance with sections 20 (2) (b) and 21 (a) of the Act.
46   Total daily extraction limits
(1)  This Plan establishes a total daily extraction limit (hereafter TDEL) from this water source for each flow class as follows:
(a)  7 ML/day for B class,
Note—
7 ML/day represents 28% of the top of B class flows for the critical month (December) and 50% of the recharge (expressed on a daily basis).
(b)  13.5 ML/day for C class:,
Note—
13.5 ML/day represents 40% of the top of C class flows for the critical month (December) and 70% of the recharge (expressed on a daily basis).
(c)  20 ML/day for D class,
Note—
20 Ml/day represents 13% of the 15th percentile flows for the critical month (December) and 70% of the recharge (expressed on a daily basis).
(d)  37 ML/day for E class, and
Note—
37 ML/day represents 30% of the 15th percentile in the critical month (December) and 70% of the recharge (expressed on a daily basis).
(e)    (Repealed)
Note—
The TDEL defines the maximum volume of water that can be extracted from this water source on any day when the flow in the Creek is at a particular flow level. The TDEL is also subject to review in accordance with clauses 76 and 77.
(2)  The TDEL for each flow class specified in subclause (1) applies to all rivers and aquifers within this water source apart from those rivers identified as minor streams in a harvestable right Order made under section 54 of the Act.
Note—
The harvestable rights Order applying to this area at the commencement of this Plan is that gazetted on 23 March 2001 under section 54 of the Act. It identifies minor streams as non-permanent 1st and 2nd order streams as shown on topographic maps.
cll 46: Am 1.7.2004.
47   Initial assignment of the TDEL to categories of access licence
The TDEL for each flow class will initially be assigned to categories of access licences according to the following:
(a)  Domestic and stock access licences:
(i)  0.2 ML/day of B class,
(ii)  0.2 ML/day of C class,
(iii)  0.2 ML/day of D class, and
(iv)  0.2 ML/day of E class.
(b)  Unregulated river and aquifer access licences:
(i)  6.8 ML/day of B class,
(ii)  13.3 ML/day of C class,
(iii)  19.8 ML/day of D class, and
(iv)  36.8 ML/day of E class.
48   Unassigned TDEL
(1)  At the commencement of this Plan, there is no unassigned TDEL.
(2)  If an access licence is surrendered, cancelled or not renewed the TDEL for unregulated river and aquifer access licences in clauses 47 shall be diminished accordingly.
Note—
While the outcome of the review at clauses 76 and 77 may result in an increase in the TDEL, this will not result in additional unassigned TDEL.
cll 48: Am 1.7.2004.
49   Daily extraction limits for individual access licence holders
(1)  Each access licence requiring an individual daily extraction limit (hereafter IDEL), as specified in Part 12 of this Plan, will be assigned the same proportion of the TDEL specified in clause 47 as its share component bears to all the share components of licences of that category.
(2)  Assignment of IDELs to access licences will occur after the review of TDELs as specified in clauses 76 and 77.
(3)  Notwithstanding subclause (1), in relation to those access licences that are currently excluded from a flow class or part of a flow class by existing conditions on the access licence or the water supply work nominated by the access licence, the IDEL resulting from subclause (1) will be adjusted to reflect as far as possible such an exclusion.
50   Granting of unassigned TDEL
There will be no unassigned TDEL for the duration of this Plan.
51   Adjustment to TDELs and IDELs
(1)  Pursuant to section 45 (1) (b) of the Act, if total extraction of water under domestic and stock or native title rights exceeds the level specified in Part 5 of this Plan:
(a)  the TDEL for unregulated river and aquifer access licences in clause 47 (b) shall be diminished to allow these additional basic landholder rights to be met, and
(b)  the IDELs of each unregulated river and aquifer access licence will then be reduced to comply with this diminished TDEL.
(2)  If the review of the very low flows specified in clauses 76 and 77 results in an amended TDEL for any flow class, then the assignment of the TDEL in a flow class to unregulated river and aquifer access licences as specified in clause 47 (b) shall be adjusted so the TDEL for the flow class is not exceeded.
Note—
The amendment of the TDEL may result in a change of the volumes assigned to unregulated river and aquifer access licences.
cll 51: Am 1.7.2004.
52   Administrative arrangements for managing access to daily flows
(1)  Notwithstanding the forgoing provisions of this Division, this Plan allows group management of access licences with respect to the IDELs.
(2)  The Minister may determine that, from the commencement of this Plan and until otherwise determined:
(a)  all access licences with IDELs shall be made part of a group maintained by the Minister, and
(b)  access licences with IDELs will be assessed as a whole against their combined IDELs.
(3)  At any time when subclause (2) does not apply:
(a)  access licence holders may make a request to form a group for their access licences,
(b)  access licence holders may have their licence removed from a group, in which case they shall be permitted to extract under that licence a maximum of the licensed IDEL, and
(c)  where an access licence is removed or added to a group, the group’s combined IDEL shall be adjusted by the amount of the IDEL on the subject access licence.
(4)  Groups will be managed according to the following rules:
(a)  daily extraction by a group cannot exceed the combined IDELs of all access licences in the group,
(b)  where it been assessed that a holder of an access licence within a group is repeatedly causing the combined IDEL to be exceeded then the Minister may remove that access licence from the group,
(c)  where daily extraction by a group exceeds the combined IDELs of all access licences in the group, then the Minister may dissolve the group and require each access licence holder to comply with the licensed IDELs,
(d)  should a holder of an access licence which is part of a group commit the IDELs of that licence to the environment consistent with section 8 (1) (c) of the Act, then those IDELs shall be removed from the group,
(e)  an access licence may not be in more than one group, and
(f)  the Minister may refuse to allow an access licence to be included in a group, and may refuse a request to form a group.
53   Infrastructure failure
(1)  In the event of infrastructure failure, the Minister can elect to:
(a)  continue to announce the current flow class,
(b)  announce another flow class based on climatic conditions and any other flow gauging information, or
(c)  restrict access to water to the lowest flow class.
Note—
Infrastructure is defined in the dictionary.
Note—
If satisfied that it is necessary to do so in the public interest, the Minister may direct the holders of an access licence to cease using a water supply work in accordance with section 323 of the Act.
Division 4 Management of local impacts
54   Management of local impacts
(1)  This Division is made in accordance with sections 21 (a) of the Act.
(2)  This Division only applies to aquifer access licences in this water source.
55   Water level management
(1)  The Minister may declare that, in order to protect groundwater levels within the aquifer in this water source, local access rules are to apply in a defined area known as a local impact area.
(2)  If water levels in any part of the aquifer in this water source have declined to such an extent that adverse impact is occurring, or is likely to occur, extraction from all water supply works (bores) within a local impact area declared under subclause (1) from which access is authorised by an aquifer access licence will be restricted to such an extent and for such time as is required to reinstate water levels to such a degree as to mitigate or avoid that impact.
Note—
This provision recognises that in some locations, at certain periods of high groundwater demand, critical water level declines may occur, and that additional extraction limitations may be required.
56   Water quality management
(1)  The beneficial uses of the aquifer in this water source are raw water for drinking, and ecosystem protection, based on beneficial use classes identified in the Australian and New Zealand Environment and Conservation Council Water Quality Guidelines 2000, and the National Health and Medical Research Council Raw Water for Drinking Purposes Guidelines 1996.
(2)  Water quality decline will be deemed unacceptable if extraction is likely to cause water quality to decline to a lower beneficial use class.
Note—
It is not recommended that the water from the aquifer in this water source be consumed directly without prior treatment. Land use activities may have polluted the groundwater in some areas.
(3)  The Minister may declare that, in order to protect water quality within the aquifer of this water source, local access rules are to apply in a defined area known as a local impact area.
(4)  If unacceptable water quality declines are resulting from extraction, extraction from all water supply works (bores) within a local impact area declared under subclause (3) from which access is authorised by an aquifer access licence will be restricted to such an extent and for such time as required to halt that decline, or restore the beneficial use of the aquifer in this water source.
57   Extraction restrictions
The Minister may, in the event of local impact restrictions arising from this Division impose, by Order, a reduction in annual, quarterly, monthly, weekly or daily extraction rates from water supply works (bores) in the affected area.
Part 11 Access licence dealing rules
58   Access licence dealing rules
(1)  This Part is made in accordance with section 20 (1) (e) of the Act and with the Minister’s access licence dealing principles gazetted on 27 December 2002 under section 71Z of the Act.
(2)  Applications for access licence dealings may be granted subject to the Minister’s access licence dealing principles gazetted from time to time under section 71Z of the Act and the rules in this Part.
Note—
There are a number of mechanisms within the Act, called access licence dealings, to change either the ownership of all or part of an access licence, or the location within a water source at which all or part of the share and extraction components of access licences can be exercised. These dealings are governed by the principles in section 5 of the Act, the Minister’s access licence dealing principles, and the rules in this Part.
Note—
Where there is an inconsistency between access licence dealing rules established in this Plan and Minister’s access licence dealing principles gazetted subsequent to the commencement of this Plan, section 71Z of the Act provides for the access licence dealing rules in this Plan to prevail.
cll 58: Am 1.7.2004.
59   Rules relating to constraints within this water source
(1)  This clause applies to any relevant dealings under sections 71Q, 71S and 71W of the Act, and section 71T of the Act with respect to water allocation assignments within this water source.
(2)  Dealings are prohibited under this clause if:
(a)  any of the access licences or water allocations involved are not within this water source, unless the dealing is permitted under clause 64,
Note—
Clause 61 relates to any dealings that involve an access licence moving from one water source to another.
(b)  prior to initial assignment of IDELs, the dealing results in the total share component of all access licences that have nominated waters supply works in the receiving management zone exceeding 10% of the total share component existing at the time of the commencement of Part 2 of Chapter 3 of the Act in this water source, unless the dealing is:
(a)  from management zone 1 to management zone 2, or
(b)  from management zone 3 to management zone 2.
(c)  after initial assignment of IDELs, the dealing would result in the access licence extraction component that had nominated a work in one management zone, nominating a work in another management zone, and the change of location is in an up-river direction, unless the sum of the IDELs held in the up-river zone remains not more than 10% greater than the sum of the IDELs in the receiving zone when IDELs are initially assigned or unless the dealing is into management zone 1 where there is no constraint, or
(d)  the dealing would result in the total extraction under aquifers access licences through nominated works in an area, plus basic landholder rights extraction in that area, causing adverse local impact in accordance with Part 10 Division 4 of this Plan.
cl 59: Am 1.7.2004; 2004 No 91, Sch 2.123.
60   Rules for access licence dealings which alter the times, rates or circumstances specified in access licence extraction components
Notwithstanding clause 59, applications under section 71S of the Act to vary the times, rates or circumstances specified in an access licence with respect to the taking of water under the licence are prohibited.
61   Rules for change of water source
(1)  This clause relates to dealings under section 71R of the Act.
Note—
Section 71R dealings are the mechanism by which access licences can move from one water source to another. Once the change in water source has been affected, if permitted, the new licence will have to nominate specified works (by a dealing under section 71W of the Act) in the receiving water source before extraction can commence.
(2)  Dealing under section 71R of the Act are prohibited in this water source, unless provided for in this clause.
(3)  An access licence with a share component specifying this water source may be cancelled and a new licence issued only if the new access licence issued is within this Unit, and the access licence dealing rules in the other water source permit such a dealing.
(4)  An access licence with a share component specifying another water source may be cancelled and a new licence issued in this water source only if:
(a)  the access licence cancelled is within this Unit,
(b)  the access licence dealing rules in the other water source permit such a dealing, and
(c)  IDELs in this water source have been assigned to access licences.
Note—
Allowing access licence share component dealings before the assignment of IDELs would distort the initial distribution of the TDELs as IDELs.
(5)  The volume of share component on an access licence issued under this clause is to be the volume of the cancelled share component multiplied by a conversion factor established by the Minister, and published in an Order made under section 71Z of the Act, that protects environmental water, basic landholder rights, and the reliability of supply to all other access licences subject to this Plan.
(6)  The extraction component of the cancelled access licence is not to be carried over to the new access licence.
62   Rules for conversion of access licence category
(1)  This clause relates to dealings under section 71O of the Act.
(2)  Conversion of an access licence of one category to an access licence of another category may be permitted only if:
(a)  the conversion is from an unregulated river or aquifer access licence to a runoff harvesting access licence,
(b)  the conversion is from unregulated river access licence to an aquifer access licence,
(c)    (Repealed)
(d)  the conversion is from unregulated river access licence to stock and domestic access licence.
(3)  The volume of share component on an access licence issued under this clause is to be the volume of the cancelled share component multiplied by a conversion factor established by the Minister, and published in an Order made under section 71Z of the Act, that protects environmental water, basic landholder rights, and the reliability of supply to all other access licences subject to this Plan.
cl 62: Am 1.7.2004.
63   Rules for interstate access licence transfer
(1)  This clause relates to dealings under section 71U of the Act.
(2)  Dealings that result in the interstate transfer of an access licence into or out of this water source are prohibited.
64   Rules for water allocation assignments between water sources
(1)  This clause relates to dealings under section 71T of the Act, in relation to water allocation assignments between water sources.
(2)  Dealing under section 71T of the Act that result in water allocation assignments to or from access licences in this water source are prohibited unless provided for in this clause.
(3)  Dealings that assign water allocations between access licences inside this water source and access licences outside this water source, but inside this Unit, are permitted only if the access licence dealing rules in the other water source permit such a dealing.
(4)  Dealings that assign water allocations between access licences inside this water source are permitted, subject to clause 59.
Note—
Each water allocation assignment must be applied for. Licence holders may enter into private contracts to assign water allocations for a number of years. Such contracts are not guaranteed by the Government, and approval must be sought annually. Approval will be subject to the rules in this Plan, including local impact assessment.
65   Rules for interstate assignment of water allocations
(1)  This clause relates to dealings under section 71V of the Act.
(2)  Dealings that result in interstate assignment of water allocations to or from this water source are prohibited.

(g)  the requirement that water may only be taken in accordance with a flow class determined by the Minister, at a rate not exceeding that specified for the flow class on the access licence extraction component, unless otherwise authorised by an approved group, or if the access licence is a runoff harvesting access licence,
(h)  the requirement that an unregulated river access licence or a runoff harvesting access licence does not authorise its holder to take water from the aquifers of this water source, and
(i)  any other conditions required to implement the provisions of this Plan.
66A   Very low flow access conditions
(1)  Notwithstanding any cease to pump conditions established on the licence, during periods of very low flows, holders of access licences listed on Schedule 6 may continue to access water to comply with the requirements of the Food Production (Safety) Act or the Prevention of Cruelty to Animals Act for the following purposes:
(a)  fruit and vegetable washing,
(b)  cleaning of dairy plant and equipment for the purpose of hygiene,
(c)  poultry watering and misting, and
(d)  cleaning of enclosures used for intensive animal production for the purposes of hygiene.

(3)  Upon written request by the holder of an access licence, the Minister may add a licence to Schedule 6, but only if the licence meets the purpose requirements established in subclause (1), and the purpose existed prior to 1 July 2004.
(4)  An access licence will be removed from the Schedule if:
(a)  any access licence dealing results in the water being extracted from a different location,
(b)  an alternative water supply is obtained, that satisfies the requirements of subclause (1), or
(c)  the licence is surrendered, cancelled, or not renewed.
(5)  Notwithstanding subclauses (1) to (4), extraction of water by an approved water supply work is only permitted if there is visible flow in the river in the vicinity of the work.
(6)  An assessment of the continuing requirements for access under this clause will be undertaken before the end of this Plan, and the Schedule amended or deleted at the end of this Plan, if such a review determines that this concessional access is no longer required.
(7)  The assessment made under subclause (6) will be undertaken for the Plan as a whole, and for each individual licence on the Schedule.

Part 13 Granting and amending water supply works approvals
71   Granting and amending water supply works approvals
This Part is made in accordance with section 21 (b) of the Act.
72   Runoff harvesting dams
(1)  New or expanded runoff harvesting dams shall, in addition to other considerations, be subject to the dam capacity not exceeding that which is consistent with the access licence specifying the runoff harvesting dam as the nominated work.
(2)  When water allocations that may be taken from a runoff harvesting dam are reduced either by the Minister, or on application of the approval holder, or by an assignment in accordance with Part 11 of this Plan, the Minister may impose an additional condition requiring the dam to be modified so as to reduce its capacity, or requiring the water taken and evaporated from the dam to be reduced, consistent with the reduction in water allocations available.
Note—
Extraction of water from a runoff harvesting dam requires a runoff harvesting access licence, unless the runoff harvesting dam is within the maximum harvestable right dam capacity for the property on which it is located, in which case no licences or approvals are required. Runoff harvesting is a category of access licence to be established by regulation under section 57 (k) of the Act.
73   In-river dams
No new in-river dams shall be approved within this water source.
Note—
Taking of water from an in-river dam requires an access licence unless it is taken in accordance with section 52 of the Act (domestic and stock rights). In either case, however, the dam requires a water management works approval unless exempted by regulation under the Act.
Part 14 Monitoring and reporting
74   Monitoring and reporting of performance indicators
The monitoring and reporting of the performance indicators specified in clause 13 shall be undertaken by the Minister.
Note—
Review and Audit of this Plan
In accordance with section 43A of the Act, the Natural Resources Commission must undertake a review of this Plan prior to any decision to extend its term or to make a new plan. The review must consider the extent to which the Plan’s water sharing provisions have contributed to achieving or not achieving the relevant natural resource management standards and targets in the catchment management area (as referred to in section 5 of the Catchment Management Authorities Act 2003).
When undertaking this review the Natural Resources Commission is required to call for public submissions. The Commission will take into consideration any submission received as well as any other relevant State-wide or regional government policies or agreements that apply to the catchment management area.
In accordance with section 44 of the Act, this Plan will be audited at intervals of no more than five years, for the purpose of ascertaining whether its provisions are being given effect to. This audit is to be carried out by an audit panel appointed by the Minister in consultation with the water management committee, where one exists.
Note—
Implementation Program
In accordance with section 51 of the Act, the Minister may establish an Implementation Program that sets out the means by which the provisions of this Plan are to be achieved.
It is proposed that the Minister establish an Implementation Program for this Plan. Pursuant to section 51 (5) of the Act, the Implementation Program is to be reviewed annually by the Minister to determine whether it is effective in implementing this Plan.
The results of the review of the Implementation Program are included in the annual report for the Department.

76   Amendment of flow levels, pool protection provisions and TDELs
(1)  The Minister may, under section 45 (1) (b) of the Act and by notice published in the NSW Government Gazette:
(a)  vary the very low flow levels, and the bottom of B class flows established in clause 17, following field verification,
(b)  vary the initial pool control levels and key sites established in clause 22 (3) (f),
(c)  vary the TDEL for any flow class as specified in clause 46, following a study of water usage and a study of the connectivity of surface water and groundwater, and/or
(d)  vary the planned environmental water specified in clause 22 as a result of any variation to a TDEL arising from subclause (1) (c).
(2)  Any variation made under subclause (1) (a) should not result in the very low flow class being greater than 1 ML/day or less than 0.5 ML/day on a falling river.
(3)  Any variation made under subclause (1) (c) should be limited to:
(a)  for B class, no more than 60% of the surface flow assessed in subclause (8) at the 50th percentile flow of all days at the flow reference point, but not less than 4 ML/day,
(b)  for C class, no more than 60% of the surface flow assessed in subclause (8) at the 30th percentile flow (of all days) at the flow reference point, but not less than 11.5 ML/day,
(c)  for D class a maximum of 6.5 ML/day above the TDEL for C class, but not less than 20 ML/day, and
(d)  for E class a maximum of 50 ML/day, but not less than 37 ML/day.
(4)  The Minister should undertake the field verification in subclause (1) (a) as soon as practical, but before the review of this Plan under section 43 (2) of the Act.
(5)  The Minister should review the pool control levels and key sites in subclause (1) (b) in conjunction with the field verification in subclause (4).
(6)  The Minister should cause the studies established in subclause (1) (c) to be undertaken after at least 3 years of measurement of use, but before the review of this Plan under section 43 (2) of the Act.
(7)  The field verification established in subclauses (1) (a) and the pool control level review in subclause (1) (b) should assess:
(a)  whether the flow level meets the objectives at clause 11 (a) and (b) of this Plan, and
(b)  whether the pool control levels and key sites meet the objectives specified in clauses 11 (a) and (i), and specifically consider the following:

Dictionary
The following definitions apply to this Plan in addition to the definitions set out in the Act:
account water is the balance in a licence water allocation account at a particular time.
Note—
A licence water allocation account records water allocations accrued under the licence as well as water allocations taken, assigned or re-credited. The operation of the account is also governed by rules for the carrying over of credits from one accounting period to the next and rules for the maximum credit that may be allowed to accumulate in the account as established in a water sharing plan. Water allocations are the shares of available water accrued under an access licence from time to time as a result of available water determinations.
abandoned refers to a water bore that is no longer being used.
conversion factor refers to the adjustment factor that is to be applied to an access licence share component when it is cancelled in one water source, and reissued in a different water source and visa versa, or when the access licence is converted from one category to another. It is designed to provide for the fact that the value of a unit of share component in terms of the average water allocations that result from it may vary from one water source to another, or from one category to another.
endangered ecological communities means ecological communities listed in Schedule 1 of the Threatened Species Conservation Act 1995 or Schedule 4 of the Fisheries Management Act 1994.
extraction limit is a limit on the amount of water that may be extracted from an extraction management unit.
extraction management unit is a group of water sources for the purpose of managing long-term annual average extraction.
farm dam is a privately owned dam typically of earthen construction designed to collect and/or store water for use on one or a few properties. It does not include publicly owned dams or weirs. See also in-river dam and runoff harvesting dam.
flow classes are categorised by the size and duration of flow levels in unregulated rivers, for example:
(a)  very low flows may be a class on their own,
(b)  low flows may be categorised as ‘A’ class,
(c)  moderate flows may be categorised as ‘B’ class,
(d)  high flows may be categorised as ‘C’ class,
(e)  very high flows may be categorised as ‘D’ class, and
(f)  extremely high flows may be categorised as ‘E’ class.
flow gauging station is a device that is used to measure the height of a river, from which the flow in the river can be calculated.
groundwater is water that occurs beneath the ground surface in the saturated zone.
groundwater dependent ecosystems are ecosystems which have their species composition and natural ecological processes wholly or partially determined by groundwater.
individual daily extraction limit (IDEL) is the volume of water that may be extracted by an individual access licence on a daily basis from a particular flow class.
infrastructure includes, but is not limited to, a:
(a)  flow gauging device or any other appliance that is used to measure the height of a river relative to a known datum point, from which the flow in the river can be calculated,
(b)  flow announcement system which is the mechanism by which the Minister communicates daily flow classes to the holders of an access licence within this water source, or
(c)  monitoring bore.
in-river dam is a dam on a 3rd, 4th or higher order river. 3rd, 4th or higher order rivers are as defined in the order made under section 5 of the Water Act 1912 in relation to the definition of a “river” gazetted 23 March 2001. See also farm dam and runoff harvesting dam.
management zone is an area within the water source to which total daily extraction limits are defined. Management zones are designated only where the water source to which the plan applies is divided into areas and total daily extraction limits are defined for each area.
monitoring bore refers to a bore constructed for the purpose of measuring water levels and/or taking samples for water quality analysis.
recharge is the addition of water, usually by infiltration, to an aquifer.
runoff harvesting dam is a farm dam on a hillside or 1st or 2nd order stream which collects and stores rainfall runoff. 1st and 2nd order streams are as defined in the order made under section 5 of the Water Act 1912 in relation to the definition of a river gazetted 23 March 2001. See also farm dam and in-river dam.
Note—
This order refers to watercourses shown as blue lines on topographic maps. The lines which are uppermost in a catchment are 1st order streams, when two 1st order streams are joined they make a 2nd order stream, etc. For more information see the Farm Dams Assessment Guide available from the Department of Land and Water Conservation.
total daily extraction limit (TDEL) is the total volume of water that may be extracted under access licences on a daily basis from a particular flow class.

Comments
Target 1c Long term average annual extraction limits which are ecologically sustainable, and which minimise downstream impacts, established in all coastal water sources
PARTIAL
  This Plan clearly sets out the basis for the extraction limit for the Goulburn Extraction Management Unit.
  Until the cumulative impact of this limit can be assessed for the Goulburn Extraction Management Unit it is not possible to properly assess ecological sustainability and downstream impacts. However application of TDELs should ensure adequate downstream flows.
Target 1e The long term average annual extractions for groundwater limited (or being phased down) to an ecologically sustainable level (the Sustainable Yield) as determined by detailed assessment of each groundwater source and consultation with the relevant management committee. In the absence of such an assessment, the following to apply: 100 percent of average annual recharge for a groundwater source where there is no significant ecosystem dependency; 70 percent of average annual recharge where there is significant ecosystem dependency
HIGH
  This Plan establishes a maximum extraction of groundwater of 70% of average annual recharge.
Target 1f Rules for adjustments to future available water determinations in the event that the extraction limits are exceeded, clearly prescribed in consultation with the relevant management committee, and acted upon
FULL
  Rules set out in Part 9 of this Plan.
Target 2 All management plans incorporating mechanisms to protect and restore aquatic habitats, and the diversity and abundance of native animals and plants, with particular reference to threatened species, populations and communities and key threatening processes
PARTIAL
  This Plan has daily extraction limits to protect/restore environmental flows.
  This Plan has improved low to very low flow protection by establishing a cease to pump and daily extraction limits for C and D class flows.
  It is not clear if the level of environmental protection provided by this Plan will be adequate to protect/improve environmental conditions as this depends on the appropriateness of the hypothesis on groundwater connectivity.
  This Plan allows for a review at year 5 of this Plan of the flow levels, pool protection measures and daily extraction limits following various hydrological and water use studies.
  There is a Healthy River Commission final report pending.
Target 4a Wherever the frequency of “end of system” daily flows would be less than 60 percent of the pre-development level without environmental water rules or extraction limits, the flows increased to 60 percent of pre-development levels or increased by at least 10 percent of the pre-development frequency
PARTIAL
  The interaction of the highly connected groundwater with the river and the impact of groundwater extraction below or adjacent to the creek is to be reviewed at year 5 of this Plan.
  In C and D classes this Plan rules appears to be an improvement on the current management system.
  This Plan also protects the first 24 hours of a flow event by delaying access to the higher class of flows by water users.
  This Plan provides for a review of the cease to pump level, the thresholds of all the flow classes and the daily extraction limits at year 5.
Target 4b Frequency of “end of system” daily very low flows (as defined by local field investigation) protected or restored to predevelopment levels to maintain or restore their critical ecological functions, drought refuges and habitat connectivity. In the absence of such local assessments, protection extended up to at least the predevelopment 95th percentile
PARTIAL
  This Plan has a cease to pump level of 0.5 ML/day and a commence to pump level of 1 ML/day. The 1 ML/day is equivalent to the 95th percentile of all days with flow.
  The interaction of the highly connected groundwater with the river is to be reviewed at year 5 of this Plan.
  This Plan provides for field verification of flows and review of the cease to pump levels during the term of this Plan.
Target 5 Access rights for water access licensees clearly and legally specified in terms of share and extraction components
PARTIAL
  This Plan establishes both share and extraction components for distribution to individual licence holders.
  This Plan enables the trading of share components and IDELs between access licences.
Target 6b For surface water sources, a pathway for reducing the share components to 200 percent of the long term average annual extraction limit to be established not later than the end of the term of the SWMOP
FULL
  Total share components for the Goulburn Extraction Management Unit should not exceed 200% of the extraction limits for this Unit.
  Groundwater share components do not exceed 125% of the sustainable yield.
Target 7 Mechanisms in place to enable Aboriginal communities to gain an increased share of the benefits of the water economy
PARTIAL
  The Government has established alternative mechanisms to address this targets.
  This Plan does provide reasonable market opportunities.
Target 8 Daily extraction components specified and tradeable, subject to metering, reporting and compliance, for at least 50 percent of unregulated river access licences and for 80 percent of stressed unregulated rivers
FULL
  This Plan establishes daily extraction limits across the whole water source.
Target 10 Degree of connectivity between aquifers and rivers assessed, and zones of high connectivity mapped to enable baseflows to the river to be maintained or improved
PARTIAL
  This Plan recognises the connectivity between surface and groundwater.
  This Plan is to review the connectivity at year 5 and changes to be made to the flow sharing rules set up by this Plan if required.
Target 11 Groundwater dependent ecosystems identified and mapped for all priority aquifers, and the ecological water requirements assessed to enable local groundwater extraction rates and/or Sustainable Yields to be reviewed
PARTIAL
  Groundwater dependency of the river environment has been recognised.
  Review mechanisms established by this Plan.
Target 12 Measures in place in all water sources subject to a gazetted water sharing plan to protect domestic and stock rights from the impact of other water access and use
LOW
  The cease to pump level of 0.5 ML/day is less than the assessed requirements for basic landholder rights of 1.8 ML/day.
  Groundwater pumping below cease to pump levels may compromise basic landholder rights access in dry periods.
Target 13 The knowledge sharing, training and resources necessary to ensure that Aboriginal people have the capacity to be effectively involved in water management identified and addressed
PARTIAL
  Two Aboriginal community representatives have been represented on the water management committee.
  A workshop was held with members of the LALC to input ideas into development of this Plan.
Target 14 Water sources, ecosystems and sites of cultural or traditional importance to Aboriginal people identified, plans of management prepared, and measures put in place to protect and improve them
PARTIAL
  This Plan does not address specific Aboriginal cultural or traditional requirements but has identified dependent ecosystems of particular importance.
  An Aboriginal respect statement was developed by local traditional landowners was adopted in the development of this Plan.
  This Plan does provide a level of environmental protection which should assist in protecting Aboriginal values.
Target 16a All share components of access licences tradeable
FULL
  Part 11 of this Plan sets out the rules for access licence dealings.
Target 16c Conversion factors and protocols established to facilitate trading and dealings between water sources, whilst also protecting existing access and environmental water
FULL
  This Plan provides for the Minister to establish conversion factors.
Target 16f Zones established where necessary for environmental protection and limits/constraints on water dealings in them made explicit
FULL
  This Plan establishes management zones for the trading of IDELs.
  This Plan establishes rules for trading and dealings within and between zones and to nearby ground water aquifers.
Target 35 All management plans incorporating water quality objectives that have considered Government approved Interim Environmental Objectives, the current Australian and New Zealand Environment and Conservation Council Guidelines and the recommendations of relevant Healthy Rivers Commission Inquiries
HIGH
  This Plan includes a generalised water quality objective.
  Committee has acknowledged water quality in Wybong Creek, particularly increasing salinity, turbidity, algae, etc as of concern and recognises salinity by proposing mandatory conditions for dams as well as protecting the first flush (24 hour rule).
  This Plan does provide a reasonable level of environmental protection which would assist in protecting water quality.
  This Plan provides for water quality management rules in Part 10 Division 4 in relation to groundwater.

  Periodic assessment of identified attributes of this water source and dependent ecosystems.
  The ecological influence of the Plan is limited to providing for changes in flow regime aimed at improving the ecological condition of the water source and dependent ecosystems.
  The focus of this performance indicator will be the effect of flow strategies.
  Information on flow requirements of ecological systems is limited so physical or hydraulic surrogates will be used to assess the influence of the Plan. For example, the status of wetted area, depth in pools and flow velocity over riffles.
  In addition to the environmental water provisions defined in this Plan, there are many other factors that contribute to achievement of ecological objectives. Riparian vegetation, water quality, farming techniques, soil erosion, water flow patterns and other catchment characteristics all significantly influence ecological condition. It is difficult to assess which factor is the most influential at a particular time and place.
  Research and development into the impacts of flow on ecological condition will be incorporated into assessment of the plan where the information is available and relevant.
