Part 2 Vision, objectives, strategies and performance indicators
9 Vision, objectives, strategies and performance indicators
This Part is made in accordance with section 35 (1) of the Act.
10 Vision
The vision for this Plan is an ecologically sustainable groundwater resource that provides an assured supply of good quality groundwater for the social and economic benefit of the people in the Gwydir Catchment.
11 Objectives
The objectives of this Plan are to:(a) protect and maintain groundwater dependent ecosystems by minimising the impacts of extraction,(b) manage and share the groundwater resources of the Gwydir Valley in a sustainable and equitable manner, while minimising negative local and regional impacts,(c) protect the structural integrity of the aquifer by ensuring extraction does not cause any aquifer compaction, aquitard compaction or land subsidence,(d) protect and maintain groundwater quality by ensuring extraction does not result in a change in the beneficial use of the aquifer,(e) provide opportunities for market based trading of groundwater rights within the extraction limit and interference constraints,(f) preserve basic landholder rights to this groundwater source,(g) ensure there are no long term declines in water levels by managing allocations and extractions within the extraction limit, and(h) protect and maintain cultural and heritage values through the management of this groundwater source.
12 Strategies
The strategies of this Plan are to:(a) establish environmental water rules and manage access to groundwater consistent with those rules,(b) establish rules for the protection of basic landholder rights,(c) establish an extraction limit for this groundwater source, taking into account the requirements of the environment,(d) reduce the total share component of access to 125% of the final extraction limit,(e) establish rules for granting of access licences,(f) establish rules for determining the groundwater available from time to time under access licences,(g) establish water allocation account management rules,(h) establish rules for minimising the local impacts of groundwater extraction on the environment, the aquifer itself, and between users,(i) establish the access licence dealing rules, and(j) establish the conditions that will apply to access licences and water supply work (bore) approvals.
13 Performance indicators
For the purpose of section 35 (1) (b) of the Act, the following indicators are to be used to determine the performance of this Plan against its objectives.(a) change in groundwater extraction relative to the extraction limit,(b) change in climate adjusted groundwater levels,(c) change in water levels adjacent to identified groundwater dependent ecosystems,(d) change in groundwater quality,(e) change in the economic benefits derived from groundwater extraction and use,(f) change in structural integrity of the aquifer,(g) extent to which domestic and stock rights requirements have been met,(h) extent to which local water utility requirements have been met,(i) extent to which native title rights requirements have been met, and(j) extent of recognition of spiritual, social and customary values of groundwater to Aboriginal people.Note—Appendix 3 details the objectives to which these performance indicators relate and the methods for assessing these indicators.
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 that the level of natural recharge to this groundwater source will vary.(2) To give effect to subclause (1), this Plan has provisions that manage:(a) the sharing of water in this groundwater source within the limits of water availability on a long-term average basis, and(b) water extractions to enable the protection of groundwater dependent ecosystems, aquifer integrity and water quality in this groundwater source.
16 Recharge
(1) The overall basis for water sharing in this Plan is the average annual recharge to this groundwater source, estimated to be 38,000 megalitres per year (hereafter ML/yr).(2) Pursuant to section 42 (2) of the Act, the average annual recharge established in subclause (1) may be varied by the Minister at 30 June 2007 following further recharge studies undertaken by the Minister.Note—The extent of impact of this change on access by licence holders is limited by clause 28.
Part 4 Environmental water provisions
17 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.
18 Environmental health water
Note—It is anticipated that the environmental health water provisions in this Part and management of local impacts provisions in Part 10 of this Plan will maintain the cultural and heritage values associated with this groundwater source (see clause 11 (h)).(1) This Plan establishes the following environmental health water rules:(a) subject to Part 10 Division 2 of this Plan, the long-term average storage component of this groundwater source, minus the basic landholder rights, minus the supplementary access permitted under clause 25, as varied by clause 29 is reserved for the environment,(b) subject to Part 10 Division 2 of this Plan 15% of the average annual recharge to this groundwater source, being 5,700 ML/yr, is reserved for the environment.(2) Pursuant to section 42 (2) of the Act, the Minister may vary the proportion of recharge reserved as the environmental health water in subclause (1) (b) at 30 June 2007, based on further studies of groundwater ecosystem dependency undertaken by the Minister.Note—The extent of impact of this change on access by licence holders is limited by the provisions in clause 28.(3) The Minister should consult with the Minister for the Environment before varying the environmental health water in accordance with subclause (2).
19 Supplementary 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.
20 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 conditions of the commitment specified in subclause (1):(a) are to be established by the Minister,(b) are to be specified on the access licence, and(c) shall be such as to ensure that there is a contribution to the objectives of this Plan.(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
21 Basic landholder rights
(1) This Part is made in accordance with sections 5 (3) and 20 (1) (b) of the Act.(2) If a landholder is unable to exercise their basic landholder rights due to interference to their supply caused by extraction from water supply works (bores) nominated by access licences:(a) the landholder’s affected water supply work (bore) may be replaced or deepened to ensure continuing access to water for basic landholder rights, or(b) basic rights water may be supplied by alternative means during critical times.(3) The Minister may impose a charge on access licence holders in this groundwater source under section 114 of the Act, as a contribution to the costs of activities or works associated with subclause (2).Note—The Minister may issue an Order under section 328 of the Act to restrict the exercise of basic landholder rights from these groundwater sources to protect the environment, for reasons of public health, or to preserve existing basic landholder rights.Note—A basic landholder right allows an owner or occupier of a landholding to take water from an aquifer underlying the land without the need for an access licence, for domestic consumption, stock watering, and native title purposes only. Those exercising basic rights from a bore must still obtain a water supply works approval for the bore. These approvals are renewable every 20 years. This is to ensure that information about bore location and condition are kept up to date, for the protection of the resource from deteriorating bores, and in the case of a pollution event.
22 Domestic and stock rights
Note—It is not recommended that the water from this groundwater source be consumed without prior treatment. Land use activities may have polluted the groundwater in some areas.(1) At the commencement of this Plan the water requirements of holders of domestic and stock rights are estimated to be a total of 700 ML/yr.Note—The volumes of water identified in subclause (2) are the total volumes of water estimated for domestic and stock rights in this groundwater source. Refer to Appendix 4 for the calculation of domestic and stock rights.(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 overlying this groundwater source, or as a result of the increase in the exercise of domestic and stock rights by existing landholders.
23 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/yr.(2) This Plan recognises that the exercise of native title rights may increase during the term of this Plan.Note—An increase in native title rights may occur as a result of the granting of native title rights under the Commonwealth’s Native Title Act 1993.
Part 6 Bulk access regime
24 Bulk access regime
(1) This Part is made in accordance with section 20 (1) (e) of the Act.(2) This Plan establishes a bulk access regime for the extraction of water under access licences in this groundwater source having regard to:(a) the environmental water provisions established under Part 4 of this Plan,(b) the requirements for basic landholder rights identified under Part 5 of this Plan, and(c) the requirements for water for extraction under access licences identified under Part 7 of this Plan.(3) The bulk access regime established in subclause (2):(a) recognises the effect of climatic variability on the availability of water as provided for under Part 3 of this Plan,(b) establishes rules according to which access licences are granted as provided for in Part 8 of this Plan,(c) recognises and is consistent with limits to the availability of water as provided for in Part 9, Division 1 of this Plan,(d) establishes rules according to which available water determinations are to be made as provided for in Part 9 Division 2 of this Plan,(e) establishes rules according to which access licences are managed as provided for in Parts 9 and 10 of this Plan, and(f) establishes rules with respect to the priorities according to which access licences are to be adjusted as a consequence of any reduction in the availability of water as provided for in Part 9 of this Plan.
Part 7 Requirements for water for extraction under access licences
25 Estimate of water requirements
(1) This Part is made in accordance with section 20 (1) (c) of the Act.(2) At the commencement of this Plan, the requirements identified for water for extraction under access licences within this groundwater source is estimated to be 70,109 ML/yr.(3) Subclause (2) includes local water utility access licences of 3,581 ML/year in this groundwater source, made up of 3,506 ML/yr for Moree, 73 ML/yr for Pallamallawa, and 2 ML/yr for Ashley.Note—Subclauses (2) and (3) represent the total volumes specified on access licences in these groundwater sources. It is not a commitment to supply that water.(4) Pursuant to section 42 (2) of the Act, at the commencement of Year 1 of this Plan the Minister should reduce the total share components of aquifer access licences in this groundwater source to 125% of the recharge established in clause 16, minus the environmental water established in clause 18, being 1.25 × (38,000 − 5,700), which equals 40,375 ML/yr.(5) Local water utility access licences, and access licences with a share component of less than 50 ML/yr will not be subject to any access licence share component reductions made in accordance with subclause (4).(6) Access licences of greater than 50 ML/yr will not be reduced below 50 ML/yr as a result of access licence share component reductions made in accordance with subclause (4).(7) At the time of commencement of Part 2 of Chapter 3 of the Act, aquifer access licences in this groundwater source with a history of extraction greater than 80% of their access licence share component, as amended by subclause (4), will have a second licence, called a supplementary water access licence.(8) The supplementary water access licence referred to in subclause (7), will have an initial share component equivalent to the history of extraction, minus 80% of their aquifer access licence share component, as amended by subclause (4).(9) The history of extraction referred to in subclauses (7) and (8) will be for each access licence the greater of:(a) the average metered extraction in the water years 1993/94 to 1997/98, or the average of the years within that period from which extraction was first measured, not exceeding the licence volumes preceding this Plan, or(b) the average metered extraction in the water years 1997/98 to 2001/02, or the average of the years within that period from which extraction was first measured, not exceeding the licence volumes preceding this Plan.(10) The metered extraction each year referred to in subclause (9) will include any extraction resulting from carryover or borrowing in those years, but will be adjusted to exclude any transfers to or from access licence equivalents in those years.(11) Share components of supplementary water access licences specified in subclause (7) will be reduced to 0 ML/yr at 30 June 2012.(12) This Plan recognises that the total requirements for water for extraction under access licences within this groundwater source may change during the term of this Plan as a result of:(a) the granting, surrender, cancellation or non-renewal of access licences,(b) the variation of a local water utility access licences under section 66 of the Act, or(c) the volumetric quantification of the share components of existing access licences that are currently non-volumetric.
Part 8 Rules for granting access licences
26 Rules for granting access licences
(1) This Part is made in accordance with sections 20 (2) (b) and 63 of the Act, having regard to the limits to water availability in this groundwater source and the need to protect groundwater dependent ecosystems, aquifer integrity and groundwater quality.(2) Access licences may be granted in this groundwater source, subject to any embargo on the making of applications for access licences made under Chapter 3 Part 2 Division 7 of the Act.(3) The Minister should declare an embargo on the making of applications for access licences in this groundwater source, other than access licences of the following kinds:(a) local water utility access licences, andNote—Pursuant to sections 66 (3) and 66 (4) of the Act, the Minister may also vary a local water utility’s entitlement to water at 5 yearly intervals, or on application of the local water utility where there is a rapid growth in population.(b) access licences resulting from an application of a type listed in section 82 (1) of the Act.(4) In applying for a new access licence, the applicant must establish the purpose and circumstance relating to that access licence, and that the share or extraction component sought will be the minimum required to meet that purpose and circumstance.(5) Access licences granted under this Part cannot extract water through a water supply work (bore) located in areas where the full extraction authorised by access licences nominating water supply works located in the area, plus the exercise of basic landholder rights, are likely to cause an adverse local impact, as outlined in Part 10 Division 3 of this Plan.(6) If an access licence share component applied for is significant, as determined by the Minister on the basis of the particular aquifer characteristics, the application will not be granted until a water supply work (bore) approval has been granted and the work constructed.(7) Once the water supply work (bore) is constructed, and the results of a pumping test or its equivalent are supplied by the applicant, in the required form and to the specification of the Minister, the access licence may be granted.(8) The share component of the access licence granted under subclause (7) will be the proportion of the share component sought that the water supply work (bore) is capable of extracting without causing any adverse local impact, as outlined in Part 10 Division 3 of this Plan.(9) Subclauses (4), (6), (7) and (8) do not apply to a new access licence arising from an application of a type listed in section 82 (1) of the Act.(10) In accordance with section 56 of the Act, all access licences in this groundwater source shall have a share component expressed as a volume in megalitres per year (ML/yr).
Part 9 Limit to the availability of water
Division 1 Long-term average extraction limit
27 Long-term average extraction limit
(1) This Division is made in accordance with section 20 (2) (a) of the Act.(2) The long-term average extraction limit for this groundwater source is initially 32,300 ML/yr, plus the total access permitted under supplementary water access licences provided for in clause 25, as varied by clause 29.
28 Variation of the long-term average extraction limit
(1) Pursuant to section 42 (2) of the Act, the Minister may vary the long-term average extraction limit established under clause 27 at 30 June 2007 as a result of:(a) any change to the average annual recharge arising from clause 16 (2), and(b) any change to the environmental health water arising from clause 18 (2).(2) If there is any change to the long-term average extraction limit arising from subclause (1) then:(a) the extraction limit will not be greater than 38,760 ML/yr, plus the total access permitted under supplementary water access licences provided for in clause 25, as varied by clause 29, and(b) the extraction limit will not be less than 25,840 ML/yr, plus the total access permitted under supplementary water access licences provided for in clause 25, as varied by clause 29.
Division 2 Available water determinations
29 Available water determinations
(1) This Division is made in accordance with section 20 (2) (b) of the Act.(2) In making an available water determination under section 59 of the Act, the Minister should consider the following rules:(a) water extraction in this groundwater source will be monitored in each water accounting year to determine if any growth in volumes extracted is occurring above the extraction limit in clause 27, as varied by clause 28, based on a comparison of the extraction limit against the average extraction within the groundwater source over that year and the preceding 2 years.Note—A water accounting year is defined in clause 34 (3).(b) if water that, pursuant to an access licence, is committed as adaptive environmental water to be left in the aquifer for environmental purposes, then for the purpose of subclause (a), the extraction will be assumed to be 100% of the available water determination,(c) if water that, pursuant to an access licence, is committed as adaptive environmental water to be extracted for environmental purposes, then for the purpose of subclause (a), the extraction will be that measured through the approved water supply work (bore),(d) total water available under aquifer access licences will be equal to the recharge established in clause 16, minus the proportion of recharge reserved as environmental health water in subclause 18, minus the total water available to local water utility access licences,(e) if the 3 year average of extraction in this groundwater source exceeds the long term average extraction limit established in clause 27 by 5% or greater, the available water determination for the following water accounting year for access licences in this groundwater source should be reduced by an amount that is assessed necessary by the Minister to return subsequent total water extraction to the long-term average extraction limit,(f) if the 3 year average of extraction in this groundwater source is less than 95% of the long-term average extraction limit established in clause 27, then the available water determination for access licences in this groundwater source shall be increased to such an extent as to allow extraction to increase to the extraction limit,(g) notwithstanding subclause (f), an available water determination shall not exceed 100% of total access licence share components to which it applies,(h) an available water determination calculated in accordance with subclauses (e) to (g) will be made each water accounting year, will apply to all access licences in the groundwater source, excepting local water utility and supplementary water access licences, and will be the same percentage for all access licence share components to which it applies,(i) a separate available water determination will be made in this groundwater source each water year for local water utility access licences, and subject to section 60 of the Act, this shall be 100% of these access licence share components,(j) an available water determination of 100% of total supplementary water access licence share components will be made in Years 1 to 3 of this Plan,(k) the available water determination for supplementary water access licences will be reduced by 1/7 each year commencing at the start of Year 4 of this Plan, and(l) there will be no water made available to supplementary water access licences from the start of Year 10 of this Plan.
Part 10 Rules for managing access licences
Division 1 General
30 Rules for managing access licences
This Part is made in accordance with sections 20 (2) (b) and 21 (a) and 21 (c) of the Act, having regard to:(a) the environmental water rules established in Part 4 of this Plan,(b) requirements for water to satisfy basic landholder rights identified in Part 5 of this Plan, and(c) requirements for water for extraction under access licences in Part 7 of this Plan.
Division 2 Water allocation account management
31 Water allocation account management
This Division is made in accordance with sections 20 (2) (b) and 21 (c) of the Act.
32 Water allocation accounts
In accordance with section 85 of the Act, a water allocation account shall be established for each access licence in this groundwater source.Note—Water allocations may be assigned to, or from, these accounts by a water allocation assignment made under section 71G of the Act, where these are allowed under rules specified in Part 11 of this Plan.
33 Accrual of water allocations
Water allocations will be accrued into water allocation accounts each water accounting year in accordance with the Minister’s available water determinations as specified in clause 29.
34 Annual accounting for water extraction
(1) Water taken from this groundwater source will be accounted for at least annually.(2) Water taken by an approved water supply work (bore) nominated by an access licence is taken to be extracted and will be periodically debited against the access licence water allocation account.(3) A water accounting year shall be the 12 month period commencing 1 July.(4) A water allocation account shall remain at or above zero at all times.(5) In any one water accounting year, subject to local impact management restrictions arising from Part 10, Division 3 of this Plan, water taken from this groundwater source under an aquifer access licence may not exceed a volume consisting of:(a) 160% of access licence share component, as amended by clause 25,(b) plus any water allocations assigned from another licence under section 71G of the Act in that year, and(c) minus any water allocations assigned to another licence under section 71G of the Act in that year.(6) Total water in any account at any time may not exceed a volume consisting of:(a) 240% of aquifer access licence share component, as amended by clause 25,(b) plus any water allocations assigned from another licence under section 71G of the Act in that year, and(c) minus any water allocations assigned to another licence under section 71G of the Act in that year.(7) A maximum of 160% of any aquifer access licence share component may be carried forward in a water allocation account from one water accounting year to the next.(8) Subclauses (5), (6) and (7) do not apply to local water utility access licences.(9) For local water utility access licences in any one water accounting year, subject to local impact management restrictions arising from Part 10, Division 3 of this Plan, water taken from this groundwater source, and total water in any water allocation account at any time may not exceed a volume consisting of:(a) 100% of the access licence share component,(b) plus any water allocations assigned from another licence under section 71G of the Act in that year, and(c) minus any water allocations assigned to another licence under section 71G of the Act in that year.(10) Allocations in a local water utility water allocation account cannot be carried over from one water accounting year to the next.(11) Subclauses (5) to (10) do not apply to supplementary water access licences.(12) For supplementary water access licences, in any one water accounting year, subject to local impact management restrictions arising from Part 10, Division 3 of this Plan, water taken from this groundwater source may not exceed the allocation resulting from the supplementary water access licence available water determination for that year.(13) Allocations in a supplementary water access licence water allocation account cannot be carried over from one water accounting year to the next.(14) Where both an aquifer access licence, and a supplementary water access licence are held, water allocations will be debited from the supplementary water access licence account, before water is debited from the aquifer access licence account.(15) Subclauses (5) to (14) do not apply to any access licence specified in Schedule 4 of this Plan.(16) Any access licence specified in Schedule 4 will be subject to the water allocation account management rules specified in that Schedule, in addition to clauses 31, 32, 33 and 34 (1) to (4).
Division 3 Management of local impacts
35 Management of local impacts
This Division is made in accordance with section 21 (a) of the Act.
36 Extraction interference between neighbouring bores
(1) The minimum allowable distance between a property boundary and extraction from new and replacement water supply works (bores) authorised to extract equal to or greater than 20 ML/yr is 200 metres.(2) New and replacement water supply works (bores) authorised to extract less than 20 ML/yr which are within 100 metres of any basic rights water supply work, will require an investigation of potential impacts on neighbouring water supply works (bores).(3) The Minister may, upon application by an access licence holder, vary the distance restrictions specified in subclause (1) if:(a) an hydrogeological study undertaken by the licence holder, and assessed as adequate by the Minister, demonstrates minimal potential for any adverse impact on existing licensed extraction,(b) all potentially affected access licence holders, and adjacent landholders have been notified by the proponent, andNote—Potentially affected access licence holders are typically neighbouring access licence holders and/or those in the near vicinity.(c) there is a process for remediation in the event that any adverse impact occurs in the future, specified as conditions on the licence.(4) Subclause (1) does not apply to extraction under existing access licences until such time as the nominated water supply work (bore) is replaced.Note—The intention of this clause is to minimise the impact of extraction under new access licences on extraction under existing access licences. It is intended to develop models to support hydrogeological assessment of the adverse impacts of new groundwater extractions on existing licensed extraction.
37 Water level management
(1) The Minister may declare that, in order to maintain water levels within this groundwater 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 a groundwater source have declined to such an extent that, in the opinion of the Minister, an 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) that are nominated by an 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 clause 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. The Department of Land and Water Conservation will identify monitoring bores, specify the target levels, and determine the method for specifying an affected area.
38 Water quality management
(1) The beneficial uses of this groundwater source are raw water for drinking, and irrigation, based on beneficial use classes identified in the Australian and New Zealand Environment and Conservation Council Water Quality Guidelines 2001, and the National Health and Medical Research Council Raw Water for Drinking Purposes Guidelines 1996.Note—It is not recommended that the water from this groundwater source be consumed without prior treatment. Land use activities may have polluted the groundwater in some areas.(2) Water quality decline will be deemed unacceptable if extraction is likely to cause water quality to decline to a lower beneficial use class.(3) The Minister may declare that, in order to protect water quality within this groundwater 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) that are nominated by an 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 this groundwater source.(5) Extraction under local water utility access licences shall be subject to restrictions under this Part, but not to such an extent as access is denied.
39 Protection of groundwater dependent ecosystems
(1) Extraction of groundwater from a new or replacement water supply work (bore) is excluded within 100 metres of high priority groundwater dependent ecosystems, or any creek or river, for those exercising basic landholder rights, and 200 metres for extraction authorised by all other access licences unless the water supply work (bore):(a) only draws water from an aquifer at depths greater than 50 metres, and(b) has an impermeable seal, constructed within the annulus of the water supply work (bore), as specified by the Minister, to isolate aquifers above 50 metres depth, and to prevent water ingress from the shallow aquifers.Note—Subclause (1) will not apply to extraction from an existing water supply work (bore) until such time as the work is replaced.(2) High priority groundwater dependent ecosystems are those listed in Schedule 5.(3) Pursuant to section 42 (2) of the Act, the Minister may identify further high priority groundwater dependent ecosystems and include them in Schedule 5 at any time, based on further studies of groundwater ecosystems dependency undertaken by the Minister.(4) The Minister should consult with the Minister for the Environment before adding further high priority groundwater dependent ecosystems to Schedule 5.Note—At the commencement of this Plan, there is not sufficient information to identify high priority groundwater dependent ecosystems within the Lower Gwydir Groundwater Source.
40 Protection of aquifer integrity
(1) The Minister may declare that, in order to protect the integrity of the aquifers within this groundwater source, local access restrictions are to apply in a defined area known as a local impact area.(2) The Minister may, on presentation of evidence of land subsidence or aquifer compaction, restrict extraction from all water supply works (bores) nominated by an access licence within a local impact area declared under subclause (1), to such an extent and for such time as to stabilise that subsidence or compaction.Note—This clause recognises that damage of aquifers through excessive water storage loss is irreversible, and destroys the resource for future water users, including the environment.
41 Extraction Restrictions
The Minister may, in the event of local impacts restrictions arising from this Division, impose, by Order, a reduction in annual, quarterly, weekly or daily extraction rates from water supply works (bores) in the local impact area.Note—The Minister will attempt to give licence holders prior notice of any local impact restrictions so as to minimise the impacts of such restrictions on access within a season.

This Plan allows for the formation of a group of access licences with respect to the sharing of local impact restrictions arising from this Division, subject to the following rules:(a) the group register will be maintained by the Minister,(b) holders of access licences must make a request to the Minister to form a group,(c) total extraction by all access licences within a group will be assessed as a whole against their combined restricted extraction and must not exceed that amount,(d) no access licence holder within the group may extract more than is permitted by Division 2 of this Part in any one water accounting year as a result of participation in a group,(e) an access licence holder may apply to be removed by the Minister from the group and the extraction by the group will be reduced by the extraction restriction of that access licence,(f) an access licence holder may apply to be added by the Minister to the group and the combined restricted extraction of the group will be increased by the extraction restriction of that access licence, and(g) the Minister reserves the right to remove a licence holder from a group where that individual causes the group extraction restriction to be exceeded, or to dissolve a group where its members exceed their combined extraction restriction.
43 Infrastructure failure
(1) The operational rules relating to local impact management may rely on water levels at specified monitoring bores.(2) In the event of a monitoring bore failure the Minister may:(a) continue with the current access rules until the monitoring bore is reinstated,(b) adjust the current access rules based on climatic conditions and any other monitoring bore information, until the monitoring bore is reinstated, or(c) rely on another monitoring bore in the area to provide information.
Part 11 Access licence dealing rules
44 Access licence dealing rules
(1) This Part is made in accordance with section 20 (1) (d) of the Act and with the Minister’s access licence dealing principles gazetted on 27 December 2002 under section 71L of the Act.Note—The Minister’s access licence dealing principles are contained in Appendix 5.(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 71L 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, 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 71L of the Act provides for the access licence dealing rules in this Plan to prevail.
45 Rules relating to constraints within a groundwater source
(1) This clause applies to any relevant dealings under sections 71D, 71F, and 71J of the Act, and section 71G of the Act with respect to allocation assignments within this groundwater source.(2) Dealings are prohibited under this clause if:(a) any of the access licences or water allocations involved are not within this groundwater source,(b) the dealing would result in the total extraction under access licences through nominated works in the area, plus basic landholder rights extraction, causing any adverse local impact in accordance with Part 10 Division 3 of this Plan,(c) the dealing would result in any increase in the total access licence share components nominating works within the Gwydir Watercourse Plan of Management area, as shown in Schedule 2,(d) the dealing would result in any increase in the total water allocations credited to access licences nominating works within the Gwydir Watercourse Plan of Management area, as shown in Schedule 2,(e) the dealing involves a supplementary water access licence, or any water allocation credited to a supplementary water access licence water allocation account,(f) the dealing involves any assignment of access rights from any access licence specified in Schedule 4,(g) the dealing involves any water allocation assignments from any access licence specified in Schedule 4, or(h) the dealing involves any nomination of works by any access licence specified in Schedule 4, other than those nominated by the licence at the commencement of this Plan.
46 Rules for change of water source
(1) This clause relates to dealings under section 71E of the Act.Note—Section 71E dealings are the mechanism by which access licences can move from one water source to another. Once the change in water source has been effected, if permitted, the new licence will have to nominate specified works (by a dealing under section 71J of the Act) in the receiving water source before extraction can commence.(2) Dealings under section 71E of the Act that change the water source to which an access licence applies are prohibited in this groundwater source.
47 Rules for conversion of access licence category

aquifer compaction refers to the reduction in the porosity (pore spaces) of an aquifer, and may result from over pumping the aquifer
available water in relation to a water management area or water source, is the water that is available in that area or water source in accordance with an available water determination that is in force in respect of that area or water source.
available water determination is a written Order by the Minister as to the availability of water for the various categories of access licence in relation to a specified water management area or water source.

drawdown refers to a lowering of the level to which water will rise in cased bores. Natural drawdown may occur due to seasonal climatic changes. Groundwater pumping may also result in seasonal and long-term drawdown.
extraction limit is the amount of the long-term average annual recharge and storage that can be extracted, on average, each water accounting year.
Great Artesian Basin is a ‘confined’ groundwater basin comprised of a complex multi-layered system of water bearing strata (porous sandstone aquifers) separated by largely impervious rock units, underlying largely arid and semi-arid landscapes to the west of the Great Dividing Range, and extending from Queensland through New South Wales and the Northern Territory, to South Australia.
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.
monitoring bore refers to a bore constructed for the purpose of measuring water levels and/or taking samples for water quality analysis.

Appendix 4 Calculation of domestic and stock rights
Requirements for Lower Gwydir Groundwater Source
A component of the Lower Gwydir Groundwater Source Water Sharing Plan is the provision of basic landholder rights to groundwater for domestic and stock purposes.
The domestic and stock requirements for the Lower Gwydir Groundwater Source was calculated for water supply works identified within the Lower Gwydir Groundwater Source. These domestic and stock water supply works are those that are not within the boundaries of a property with a groundwater access licence, and do not form part of a local water utility access licence.
It is difficult to measure extraction from these water supply works as their use is not metered. The domestic and stock requirements in this Plan of 694 ML/yr is likely to be an overestimate, the Gwydir Groundwater Management Committee agreed that this figure be included in this Plan and understood the process used in estimating this figure.
The following assumptions were made to calculate the requirements for basic rights domestic and stock extraction:
• each property has an equivalent domestic use irrelevant of the size of the property,
• drinking, cooking, bathing, washing of clothes and cars and other domestic purposes is 0.064 ML/yr per person,
• the average house hold has 4 residents,
• average garden usage is 2 ML/yr,
• stock use is assumed to be the Dry Sheep Equivalent, and the average consumption per head per day is 6 litres (Management options during a drought, NSW Agriculture, 1986),
• at a carrying capacity of 4 head/hectare, and
• there may be other sources of water including water from creeks/rivers, dams and tanks.
Calculations
Domestic—A per property usage | ||
4 × 0.064 | = | 0.256 ML/yr |
Garden | = | 2.000 ML/yr |
Total Domestic Use | = | 2.250 ML/yr |
Stock | ||
6L/d×365 days × 4 (sheep/ha)/1,000,000L | = | 0.0088 ML/yr/ha |
Total Domestic and Stock Requirements
214 properties, with a total area of 26,484 hectares were identified in the Lower Gwydir Groundwater Source as having domestic and stock water supply work(s). The total domestic and stock demand is therefore 694 ML/yr, with 482 ML/yr and 212 ML/yr for domestic use and stock use respectively.
Future Development
Based on historical development of stock and domestic water supply works in the Lower Gwydir Groundwater Source it is estimated that there will be a growth rate of 21% over the period of the water sharing plan, an additional 42 domestic and stock water supply works to access basic landholder rights.
It is assumed that all new domestic and stock water supply works will be drilled and constructed on separate properties. The existing data indicates that the average size of these properties would be 81.5 hectares. The total additional stock and domestic requirements for the period of this Plan will be 125 ML/yr. This is 94.5 ML/yr and 30.5 ML/yr for domestic use and stock use respectively.

Part 2 General principles
7 Impacts on water sources
(1) Dealings should not adversely affect environmental water and water dependent ecosystems as identified in any relevant management plan.(2) Dealings should be consistent with any strategies to maintain or enhance water quality identified in any relevant management plan.(3) In unregulated river water sources, dealings should not increase commitments to take water from water sources or parts of water sources identified in any relevant management plan as being of high conservation value.(4) In unregulated river water sources or a groundwater sources, dealings should not increase commitments to take water from water sources or parts of water sources above sustainable levels identified in any relevant management plan.(5) In regulated river water sources, dealings should not increase daily demand for water delivery at those locations and times where it is identified in any relevant management plan that demand exceeds delivery capacity.(6) In regulated river water sources, dealings should not increase commitments to take water in lower river or effluent systems where this will result in flow at greater than 80% of channel capacity for more than 10% of days used for water delivery.(7) In this clause, commitments to take water refers, in relation to all access licences with nominated works in that water source or part of a water source, to:(a) the total volume of share components, or(b) the total volume of water allocations in water allocation accounts, or(c) where relevant, the sum of limits on rates of extraction in extraction components.
8 Impacts on indigenous, cultural, heritage or spiritual matters
(1) Dealings should not adversely affect geographical and other features of indigenous significance.(2) Dealings should not adversely affect geographical and other features of major cultural, heritage or spiritual significance.
9 Impacts on water users
(1) Dealings should not adversely affect the ability of a person to exercise their basic landholder rights.(2) Dealings should have no more than minimal effect on the ability of a person to take water using an existing approved water supply work and any associated access licences. This should be addressed by constraints on dealings established in access licence dealing rules in relevant management plans.
10 Maximising social and economic benefits
(1) The objective of access licence dealings is to help to facilitate maximising social and economic benefits to the community of access licences as required under the objects of the Act. Dealings do this by:(a) allowing water to move from lower to higher value uses, and(b) allowing the establishment of water markets that value the access licences, thereby encouraging investment in water efficient infrastructure, and(c) allowing greater flexibility to access licence holders.(2) Subject to other principles in this order, access licence dealing rules should allow maximum flexibility in dealings to promote the objectives set out in subclause (1).
Part 3 Principles for specific types of access licence dealings
11 Transfer of access licences
(1) This clause applies to dealings under section 71A of the Act.(2) Dealings under section 71A are prohibited:(a) if there is an outstanding debt under the Act in respect of the licence, or(b) if the licence is suspended under section 78 of the Act.(3) Access licence dealing rules established by a management plan shall not regulate or prohibit dealings under section 71A of the Act.Note—as indicated in section 71A (3), consent to the transfer of a local water utility access licence may only be granted if the transferee is a local water utility, and consent to the transfer of a major water utility access licence may only be granted if the transferee is a major water utility.
12 Conversion of access licence to new category

(conveyance) or category estuarine or category coastal, or(b) if there is an outstanding debt under the Act in respect of the licence, or(c) if the licence is suspended under section 78 of the Act, or(d) if the licence is of a kind which is not subject to embargo in accordance with an order made under sections 80 or 81 of the Act, or(e) if the licence share component is not numerically quantified.(3) Dealings under section 71B are prohibited unless provisions of the relevant management plan:(a) protect environmental water from being affected by such dealings, and(b) protect basic landholder rights from being affected by such dealings, and(c) protect the available water under other access licences from being affected by such dealings.(4) The share and extraction components of a new licence issued under a dealing under section 71B must comply with any requirements that are specified in the relevant management plan for a licence granted under section 63 of the Act for the new category.(5) Except for where it is otherwise specified in access licence dealing rules in the relevant management plan or where this dealing is accompanied by a dealing under section 71E, water allocations remaining in the water allocation account of the cancelled licence are to be credited to the new licence, up to a maximum of the share component volume of the new licence.(6) The share component on a new access licence issued under a dealing under section 71B is to be of a volume equal to the volume on the cancelled licence multiplied by a conversion factor determined by the Minister in accordance with any rules set out in relevant management plans.(7) Conversion factor rules in management plans:(a) must be based on protecting environmental water and basic landholder rights as specified in the management plans, and maintaining available water to other access licences, and(b) are not to be set for the purpose of achieving a reduction in overall water extraction
