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 to ensure the ecological, social, cultural and economic sustainability of the Lower Macquarie Groundwater Sources.

11 Objectives

The objectives of this Plan are to:

(a)  maintain, and if necessary restore groundwater dependent ecological processes and biodiversity,

Note—

Subclause (a) is an environmental objective. The outcomes of this objective would include: the identification of dependent ecosystems and their critical ecological processes; identification and measurement of key indicators of dependent ecosystem health; the implementation of management systems to support high priority dependent ecosystems’ ecological processes and, the environmental impacts of management change as assessed against the Vision.

(b)  optimise or maximise the social outcomes of groundwater management,

Note—

Subclause (b) is a social objective. The outcomes of this objective would include: no decline in groundwater quality as a result of extraction; sustainable groundwater source for present and future generations; priority of access for town water supply and basic rights; and social impacts of management changes defined and assessed against the Vision.

(c)  contribute to a sustainable regional economy,

Note—

Subclause (c) is an economic objective. The outcomes of this objective would include: access to the resource clearly defined (reliability, trading and other management); and, economic impacts of management changes defined and assessed against the Vision.

(d)  recognise and respect Aboriginal cultural responsibilities and obligations to the landscape, and

(e)  preserve and enhance the cultural benefits and values derived from groundwater.

Note—

Subclauses (d) and (e) are cultural objectives. The outcomes of these objectives would be to have the cultural benefits and values of the Lower Macquarie Groundwater Sources identified, and the cultural impacts of management changes defined and assessed against the Vision.

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 each groundwater source, taking into account the requirements of the environment,

(d)  reduce the total share component of access licences to the final extraction limit,

(e)  establish rules for the 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, on 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.

cl 12: Am 2006 (593), Sch 1 [3].

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 limits,

(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 economic benefits derived from groundwater extraction and use,

(f)  change in structural integrity of the aquifer,

(g)  extent to which domestic and stock rights 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 these groundwater sources will vary.

(2)  To give effect to subclause (1), this Plan has provisions that manage:

(a)  the sharing of water in these groundwater sources 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 these groundwater sources.

16 Recharge

(1)  The overall basis for water sharing in this Plan is the average annual recharge to each groundwater source as follows:

(a)  25,500 megalitres per year (here after ML/yr) plus the requirements for basic landholder rights at the commencement of this Plan in Zone 1,

(b)  26,600 ML/yr plus the requirements for basic landholder rights at the commencement of this Plan in Zone 2,

(c)  11,000 ML/yr plus the requirements for basic landholder rights at the commencement of this Plan in Zone 3,

(d)  6,000 ML/yr plus the requirements for basic landholder rights at the commencement of this Plan in Zone 4,

(e)  undefined in Zone 5, and

(f)  9,600 ML/yr plus the requirements for basic landholder rights at the commencement of this Plan in Zone 6.

(2)  A review of recharge for each groundwater source should be undertaken by the Minister by 30 June 2008 of this Plan, that should:

(a)  recommend an average annual recharge for Zone 5, and

(b)  recommend any changes to the average annual recharge for Zones 1, 2, 3, 4 and 6.

(3)  The Minister may under section 45 (1) (b) of the Act amend subclause (1) after 30 June 2010 to vary the average annual recharge values for each of these groundwater sources, following the review undertaken in subclause (2) and this variation should:

(a)  establish the average annual recharge in Zone 5, and

(b)  revise the estimated average annual recharge for each of Zones 1, 2, 3, 4 and 6.

(4)  The Minister should undertake a second review of the average annual recharge for each groundwater source by the 30 June 2014.

(5)  The Minister may under section 45 (1) (b) of the Act amend subclause (1) after 30 June 2015 to vary the average annual recharge values for each of these groundwater sources, following the second review undertaken in subclause (4).

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 Planned environmental water

Note—

It is anticipated that the planned environmental water provisions in this Part and management of local impact provisions in Part 10, Division 3 of this Plan will also protect the cultural and spiritual values of groundwater (see clause 11 (e)).

(1)  This Plan establishes the following planned environmental water rules:

(a)  subject to Part 10 Division 2 of this Plan, the physical water contained in the storage component of these groundwater sources, minus the amount required for supplementary water access permitted under clause 25D, as varied by clause 29 will be reserved for the environment,

(b)  subject to Part 10 Division 2 of this Plan, 15% of an amount that is equal to the average annual recharge to these groundwater sources, excluding Zone 5, minus basic landholder rights at the commencement of this Plan, is reserved for the environment and Aboriginal cultural heritage.

Note—

Access to water under supplementary water access licences in these groundwater sources will not be permitted after the 30 June 2016 and the physical water contained in the storage component of these groundwater sources plus 15% of the long-term average annual recharge of these groundwater sources minus an amount for basic landholder rights requirements at the commencement of this Plan will be reserved for the environment.

(2)  A review of the proportion of recharge in subclause (1) (b) reserved as planned environmental water in these groundwater sources using the best available science should be undertaken by the Minister after 30 June 2008 and should:

(a)  recommend the proportion of the annual recharge to be reserved for the environment and Aboriginal cultural heritage in Zone 5,

(b)  recommend any change to the proportion of the annual average recharge to be reserved for the environment and Aboriginal cultural heritage in each of Zones 1, 2, 3, 4 and 6, and

(c)  identify groundwater dependent ecosystems, establish their groundwater requirements and recommend appropriate management options to protect them.

Note—

The studies may recommend management options other than reservation of a portion of recharge to protect groundwater dependant ecosystems.

(3)  The Minister may under section 45 (1) (b) of the Act, amend subclause (1) (b) after 30 June 2010 to vary the proportion of recharge reserved as planned environmental water in each of these groundwater sources, based on the review undertaken in subclause (2), and this variation should:

(a)  establish the proportion of the annual average recharge to be reserved for the environment and Aboriginal cultural heritage in Zone 5,

(b)  if required, change the proportion of the annual average recharge to be reserved for the environment and Aboriginal cultural heritage in each of Zones 1, 2, 3, 4 and 6, and

(c)  designate further high priority groundwater dependent ecosystems, and include them in Schedule 4.

(4)  The Minister should undertake a second review of the proportion of the average annual recharge reserved as planned environmental water in each groundwater source, by 30 June 2014.

(5)  The Minister may under section 45 (1) (b) of the Act, amend subclause (1) after 30 June 2015 to vary the proportion of the average annual recharge reserved as planned environmental water, as varied by subclause (3), following a review established in subclause (4).

(6)  The Minister shall cause to have undertaken an independent evaluation of the reviews established in subclauses (2) and (4) prior to any change to this Plan in accordance with subclauses (3) and (5).

(7)  The Minister should seek advice from the Water Management Committee, or in its absence an advisory committee established by the Minister, including, where possible, representatives of domestic and stock rights and groundwater users, local water utilities, irrigation and industry, Aboriginal persons and environment groups before making any changes to this Plan under subclauses (3) and (5).

Note—

The extent of impact of these changes on access by licence holders is limited by the provisions in clause 28.

(8)  Any change in planned environmental water arising from subclauses (3) and (5) shall not result in the proportion of recharge reserved for the environment being less than 10%, or greater than 30% in any groundwater source.

20 Adaptive environmental water

(1)  Water may be committed in these groundwater sources for environment purposes by an adaptive environmental water condition pursuant to section 8B of the Act.

(2)  The holder of an access licence may request that the Minister impose an adaptive environmental water condition in respect of the whole or a part of the share component of the access licence.

(3)  The condition imposed under subclause (2) will continue until the holder requests its removal.

(4)  An access licence may be held by the Minister, a catchment management authority or other public body to the extent that the whole or part of that access licence has been surrendered as a result of on farm water savings made by works or other improvements, subject to:

(a)  the share component of the access licence held being equal to the value of the on-farm water savings made,

(b)  the access licence held being the highest priority category in these groundwater sources, other than a specific purpose category, and

(c)  an adaptive environmental water condition being imposed on the access licence and that condition not being removed.

(5)  The adaptive environmental water condition specified in subclause (1) and the plan for implementation of that condition, as required by section 8E (7) of the Act:

(a)  are to be established by the Minister, and

(b)  shall be such as to ensure that there will be a contribution to the objectives of this Plan.

(6)  The allocation of water for access licences with an adaptive environmental water condition will be in accordance with the available water determination for the relevant category of access licence under this plan.

(7)  If the adaptive environmental water condition on an access licence requires the water to be left in the water source for environmental purposes, then the water allocation account is to be debited when the water is available in accordance with the adaptive environmental water condition on the access licence.

(8)  If the adaptive environmental water condition requires the environmental water to be taken from the water source then the water allocation account is to be debited when it is taken.

(9)  For the purposes of auditing compliance with the extraction limit under this plan, the delivery of water pursuant to an access licence that has been committed as adaptive environmental water shall be accounted for as extraction where it occurs pursuant to a licence under subclause (2) or subclause (4).

(10)  To the extent that the water allocation of an access licence which is subject to an adaptive environmental water condition is not required to meet the requirement of the condition it may be the subject of an assignment dealing in accordance with the Dealings Rules in this plan.

(11)  Notwithstanding subclause (10) an access licence with an adaptive environmental water condition may be the subject of any other dealing permitted by the Dealing Rules in this plan, provided the benefit to the environment provided for in the adaptive environmental condition is not diminished.

(12)  At the commencement of this clause, there were no access licences with an adaptive environmental water condition in these groundwater sources.

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 of their supply by extraction authorised by access licences:

(a)  the Minister may amend a water supply works approval to allow the landholder’s affected bore to be replaced or deepened to ensure continuing access to water for basic landholder rights, or

(b)  the Minister may amend another water supply works approval so that basic rights water may be supplied by an alternative water supply work during critical times.

(3)  In accordance with the legislative requirements, the Minister may impose a charge on access licence holders in these groundwater sources under section 114 of the Act, as a contribution to the costs of activities or works associated with subclause (2).

(4)  Basic landholders rights exercised under section 52 of the Act must be exercised in accordance with any guidelines established by the Minister with respect to the reasonable use of water for domestic consumption and stock watering by landholders authorised to use water for either or both of those purposes.

Note—

The Minister may, by order made under section 323 of the Act, impose temporary restrictions on basic landholder rights when it is necessary to do so in the public interest, such as to cope with a water shortage or threat to public health or safety.

Note—

The Minister may enforce any reasonable use guidelines by serving orders on individual landholders under section 325 of the Act. The Minister may also order individual landholders accessing basic landholder rights to take specified measures to protect the environment, to preserve basic landholder rights or to overcome a threat to public health under section 328 of the Act.

cl 21: Subst 2006 (593), Sch 1 [8].

22 Domestic and stock rights

Note—

It is not recommended that the water from these groundwater sources 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 1,730 ML/yr, comprising:

(a)  70 ML/yr in Zone 1,

(b)  315 ML/yr in Zone 2,

(c)  520 ML/yr in Zone 3,

(d)  215 ML/yr in Zone 4,

(e)  445 ML/yr in Zone 5, and

(f)  165 ML/yr in Zone 6.

(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 these groundwater sources, 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 these groundwater sources 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,

(f)  LWU is the total of local water utility access licence share components for the respective Zone at the commencement of this Plan,

(g)  SD is the total of domestic and stock access licences for the respective Zone at the commencement of the Plan, and

(h)  ΣSC is the sum of share components specified in Column 3 of Schedule 5.

(4)  For the purposes of subclause (3) and clause 25D HOE, if the maximum water extraction in any one year during the period from 2000/01 to 2002/03 was less than or equal to 150% of the maximum water extracted in either 1998/99 or 1999/00, or was less than or equal to 50 ML, then the HOE will be the average metered extraction from 1998/99 to 2002/03 excluding zero and low extraction years since activation.

(5)  For the purposes of subclause (3) and clause 25D HOE, if the maximum water extraction in any one year during the period from 2000/01 to 2002/03 was greater than 150% of the maximum water extracted in either 1998/99 or 1999/00, and was more than 50 ML, then the HOE will be calculated from the following formula:

 

Note—

The rules for determining HOE are contained in Appendix 4.

(6)  For the purposes of subclauses (4) and (5) zero and low extraction years are years where extraction was less than 20% of the maximum volume of water extracted in any one year up to and including the 2001/02 water year.

(7)  For the purposes of subclauses (4) and (5) activation is defined as the first year up to and including the 2001/02 water year in which a licence holder extracted 20% or more of the maximum volume of water extracted in any one year between 1995/96 and 2001/02.

(8)  It is estimated that at the time of commencement of this Plan, the share components of aquifer access licences authorised to extract water from theses groundwater sources will total 65,524 ML/yr, distributed as follows:

(b)  SC_AAL is the share component of the aquifer access licence established under clause 25C (2),

(c)  SC_SWAL is the share component for the supplementary water access licence.

Note—

Not all aquifer access licences amended under clause 25C (3) will receive a supplementary water access licences. Only those licences who have a HOE as defined in subclause (2) which is greater than their new aquifer access licence share component.

(3)  It is estimated that at the time of commencement of this Plan the sum of supplementary water access licences established under subclauses (1) for these groundwater sources will total 2,399 ML and distributed as follows:

(a)  1,172 ML for Zone 1,

(b)  395 ML for Zone 3,

25E Changes to share components

(1)  This Plan recognises that the total requirements for water for extraction within these groundwater sources may change during the term of this Plan as a result of:

(a)  the granting, surrender or cancellation of access licences, or

(b)  the variation of local water utility access licences under section 66 of the Act.

(2)  Pursuant to section 68A of the Act the share component of each supplementary water access licence in these groundwater sources will be reduced to 0 ML on 1 July 2015.

(3)  Pursuant to section 77A of the Act supplementary water access licences will be cancelled after 1 July 2015.

cll 25A–25E: Ins 2006 (593), Sch 1 [10].

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), 61 and 63 of the Act, having regard to the limits to water availability in these groundwater sources and the need to protect groundwater dependent ecosystems and groundwater quality.

(2)  Applications for access licences may be made and access licences granted in these groundwater sources if they are for:

(a)  a specific purpose access licence for which application is provided for under clause 19 of the Water Management (General) Regulation 2004 (hereafter the Regulation) in accordance with section 61 (1) (a) of the Act,

Note—

At the commencement of this Plan, clause 19 of the Regulation provides for the following specific purpose access licences to be applied for:

(a)  a local water utility access licence (subcategory “domestic and commercial”), for the purpose of domestic consumption and commercial activities,

(b)  a domestic and stock access licence (subcategory “domestic”), for the purpose of domestic consumption,

(c)  an aquifer access licence (subcategory “town water supply”), for the purpose of supply to communities for domestic consumption and commercial activities, and

(d)  any category of specific purpose access licence (subcategory “Aboriginal cultural”), for Aboriginal cultural purposes.

Note—

Pursuant to sections 66 (3) and 66 (4) of the Act, the Minister may also vary a local water utility’s share component at 5 year intervals, or on application of the local water utility where there is rapid growth in population.

(b)  an access licence with a zero share component in accordance with sections 61 (1) (b) and 63 (5) of the Act,

(c)  an access licence that may be granted in accordance with a dealing that is permitted by Part 11 of this Plan.

(3)  In applying for a new access licence, the applicant must establish the purpose and circumstances relating to that access licence, and that the share and extraction component sought will be the minimum required to meet that purpose and circumstance.

(4)  Access licences granted under this Part cannot be used to extract water through a water supply work (bore) located in areas where the extraction authorised by the access licence plus the full extraction authorised by existing access licences nominating water supply works (bores) located in the area and the exercise of basic landholder rights, are likely to cause an adverse local impact, as outlined in Part 10 Division 3 of this Plan.

(5)  An access licences may be granted in these groundwater sources where:

(a)  a Water Act 1912 licence was not converted at the commencement of this plan, or

(b)  a licence is found to be taking water from a water source in this plan but has been incorrectly identified as taking of water from another groundwater source and the licence is cancelled in the other water source.

(6)  Aquifer access licences granted under subclause (5) shall be subject to the rules specified in clauses 25C and 25D.

cl 28: Subst 2006 (593), Sch 1 [13].

28A Compliance with extraction limits

(1)  Water extraction in these groundwater sources will be monitored each water year to determine if there is any growth in volume extracted above the extraction limit specified in clause 27 as amended by clause 28, based a comparison of the extraction limit against the average extraction within each groundwater source over that year and the preceding 2 years.

(2)  For the purposes of auditing compliance with the extraction limit, if water that:

(a)  pursuant to an access licence is committed as adaptive environmental water to be left in the aquifer for environmental purposes, then extraction will be assumed to be equal to 100% of the available water determination made under clause 29, or

(b)  pursuant to an access licence is committed as adaptive environmental water to be extracted for environmental purposes, then extraction will be that measured through the approved water supply work (bore).

(3)  If the 3 year average of extraction in a groundwater source in this Plan exceeds the extraction limit established in clause 27 by 5% or greater, then the available water determination made for aquifer access licences under clause 29 (6) and clause 29 (7) for the following water year, should be reduced by an amount that is assessed necessary by the Minister to return subsequent total water extraction to the extraction limit for that groundwater source.

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)  Pursuant to section 58 (4) of the Act, this Plan amends the relative priorities of the categories of aquifer access licence and supplementary water access licence to the extent necessary to legally make the available water determinations set out in this clause.

(3)  All available water determinations in these groundwater sources shall be expressed as either:

(a)  a percentage of the share component for all access licences where share components are specified as megalitres per year, or

(b)  megalitres per unit of share component for all access licences where share components are specified as a number of shares.

(4)  An available water determination for each category of access licence in these groundwater sources should be made at the commencement of each water year.

(5)  The available water determinations made at the commencement of the water year for domestic and stock and local water utility access licences should be 100% of share components.

(6)  The available water determination made at the commencement of the water year for aquifer access licences should be such that the total of available water determinations for each water source under this clause equals the extraction limit for the water source set in clause 27 (2) as varied by clause 28 (2) minus the total requirements for basic landholder rights, minus the total available water determinations for domestic and stock and local water utility access licences and supplementary water access licences, or such lower amount as results from the operation of clause 28A (3) or subclause (7).

(7)  The available water determination for all aquifer access licences in Zone 5 and Zone 6 will not exceed 1 ML per unit of share component.

(8)  The available water determination made at the commencement of this plan for supplementary water access licences should be 0.9 ML per unit of share component.

(9)  The available water determination made at the commencement of each water year after the 2006/07 water year for supplementary water access licences will be reduced by a further 0.1 ML per unit of share component.

(10)  The available water determination for supplementary water access licences will be reduced to 0 ML per unit of share component at the commencement of the 2015/16 water year.

Note—

Subclause (8) means that allocations for supplementary water access licences will diminish each year by 0.1 ML per unit share. For example, the available water determination for the 2006/07 water year is 0.9, the 2007/08 water year is 0.8, the 2008/09 water year is 0.7, the 2009/10 water year is 0.6, the 2010/11 water year is 0.5, the 2011/12 water year is 0.4, the 2012/13 water year is 0.3, 2013/14 water year is 0.2, the 2014/15 water year is 0.1, and the 2015/16 water year is 0.

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)  To minimise interference between extraction under different access licences in Zones 1, 2 and 6, extraction from a new water supply work (bore) nominated by an access licence shall not be permitted within:

(a)  1,000 metres (hereafter m) of an existing water supply work (bore) nominated by an access licence, if the new water supply work (bore) will extract up to and including 10 ML/day,

(b)  2,000 m of an existing water supply work (bore) nominated by an access licence, if the new water supply work (bore) will extract greater than 10 ML/day and up to and including 20 ML/day, and

(c)  3,000 m of an existing water supply work (bore) nominated by an access licence, if the new water supply work (bore) will extract greater than 20 ML/day.

(2)  To minimise interference between extraction under different access licences in Zones 3, 4 and 5 extraction from a new water supply work (bore) nominated by an access licence shall not be permitted within:

(a)  1,000 m of an existing water supply work (bore) nominated by an access licence, if the new water supply work (bore) will extract up to and including 5 ML/day,

(b)  2,500 m of an existing water supply work (bore) nominated by an access licence, if the new water supply work (bore) will extract greater than 5 ML/day and up to and including 10 ML/day,

(c)  3,500 m of an existing water supply work (bore) nominated by an access licence, if the new water supply work (bore) will extract greater than 10 ML/day and up to and including 15 ML/day, and

(d)  4,000 m of an existing water supply work (bore) nominated by an access licence, if the new water supply work (bore) will extract greater than 15 ML/day.

(3)  The distances and daily extraction rates referred to in subclauses (1) and (2) shall be specified on the new water supply work (bore) approval.

(4)  All new water supply works (bores) that are screened, slotted, or in any way open, within the Great Artesian Basin sandstone aquifers, shall have an annual extraction limit of 500 ML/yr.

(5)  Notwithstanding the provisions of subclauses (1), (2), and (4), the Minister may, upon application by an access licence holder, vary the distance restrictions specified in this clause 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 have been notified by the proponent, and

Note—

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.

(6)  Subclauses (1) to (3) do not apply to extraction under existing access licences.

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 these groundwater sources, 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 an adverse impact is occurring, or is likely to occur, extraction from all water supply works (bores) nominated by an access licence within a local impact area declared under subclause (1) shall 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.

(3)  An adverse impact in subclause (2) shall be considered to have occurred if the Minister considers that excessive drawdown has occurred, or if::

(a)  the average of the seasonally recovered water levels over a 5 year period is not maintained within 10% of the total available drawdown below the initial seasonally recovered water level over the 5 year period, or

(b)  if the seasonally recovered water levels are not maintained within 20% of the total available drawdown below the July 2002 water level.

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, and determine the method for specifying an affected area. The total available drawdown is defined by the height of the piezometric level above the bedrock (i.e. base of the groundwater source). Groundwater levels will be measured in the winter months of June, July or August allowing the aquifer to recover from the previous pumping season.

38 Water quality management

(1)  The beneficial uses of these groundwater sources, 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, are:

(a)  raw water for drinking purposes, and

(b)  agricultural water,

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)  A baseline of electrical conductivity (hereafter EC), against which changes in the salinity of groundwater will be measured, will be set in year 6 of this Plan based on the results of a salinity monitoring program undertaken by the Minister.

(5)  The EC limits adopted by this Plan for the beneficial use categories are as follows:

(a)  800 EC for Raw Water for Drinking Supplies Class, and

(b)  1,500 EC for Agricultural Water Class.

Note—

These are the limits specified in Guidelines for Groundwater Protection in Australia, Australian and New Zealand Environment and Conservation Council and Agriculture and Resource Management Council of Australia and New Zealand, (1995, as adopted by the NSW Government Groundwater Quality Protection Policy 1997).

(6)  If, for groundwater of less than or equal to 800 EC, as established by the salinity baseline set by subclause (4), there is an increase in salinity of more than 20% of the difference between the salinity baseline set by subclause (4) and the beneficial use class limits established in subclause (5) (a), then:

(a)  the Minister may declare a local impact area,

(b)  access licence holders within the local impact area will need to demonstrate to the Minister that continual extraction, or a proposed new extraction regime, will not have an unacceptable impact on the groundwater quality of the aquifer, and

(c)  until such time that this justification to continue to extract has been assessed and approved by the Minister:

(i)  extraction from water supply works nominated by an access licence within the local impact area will be restricted to such an extent and for such time as required to halt that salinity increase, or

(ii)  access licence holders may be issued with a directive to cease to pump.

(7)  If, for groundwater of greater than 800 EC and less than or equal to 1,500 EC, as established by the salinity baseline set by subclause (4), there is an increase in salinity of more than 20% of the difference between the salinity baseline set by subclause (4) and the beneficial use class limit established in subclause (5) (b), then:

(a)  the Minister may declare a local impact area,

(b)  access licence holders within the local impact area will need to demonstrate to the Minister that continual extraction, or a proposed new extraction regime, will not have an unacceptable impact on the groundwater quality of the aquifer, and

(c)  until such time that this justification to continue to extract has been assessed and approved by the Minister:

(i)  extraction from water supply works nominated by an access licence within the local impact area shall be restricted to such an extent and for such time as required to halt that salinity increase, or

(ii)  access licence holders may be issued with a directive to cease to pump.

(8)  If there is an increase in salinity from extraction that results in the current beneficial use class salinity limit being exceeded, then subclauses (7) (a) and 7 (c) shall apply.

39 Protection of groundwater dependent ecosystems

(1)  Extraction of groundwater from a new or replacement water supply work (bore) is excluded:

(a)  within 100 m of high priority groundwater dependent ecosystems for water supply works (bores) exercising basic rights,

(b)  within 200 m of high priority groundwater dependent ecosystems for water supply works (bores) nominated by an access licence, and

(c)  within 40 m of any river for any works.

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 4.

(3)  The Minister may under section 45 (1) (b) identify further high priority groundwater dependent ecosystems and include them in Schedule 4 at the end of the 2009/10 water year and at the end of the 2014/15 water year , based on further studies of groundwater ecosystem 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 4.

cl 39: Am 2006 (593), Sch 1 [18].

40 Protection of aquifer integrity

(1)  The Minister may declare that, in order to protect the integrity of the aquifers within these groundwater sources, 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.

41 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 local impact area.

42 Group registration

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 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 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 71Z of the Act provides for the Minister’s access licence dealing principles to prevail.

cl 44: Subst 2006 (593), Sch 1 [19].

45 Rules relating to constraints within a groundwater 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 allocation assignments within these groundwater sources.

(2)  Dealings are prohibited under this clause if:

(a)  any of the access licences or water allocations involved are not within these groundwater sources, or

(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, or otherwise.

cl 45: Am 2006 (593), Sch 1 [20].

46 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 effected, 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)  Dealings under section 71R of the Act that change the water source to which an access licence applies are prohibited in these groundwater sources.

(3)  An access licence with a share component specifying one of these groundwater sources may be cancelled and a new licence issued specifying another of these groundwater sources only if the total share components of all access licences in the groundwater source in which the access licence is issued remains below the extraction limit for that groundwater source established in clause 27, as amended in clause 28.

(4)  Notwithstanding subclause (3), a new licence specifying Zone 3, 4 or 5 may not be issued following cancellation of an access licence in Zone 1, 2, or 6.

(5)  The volume of the share component on an access licence issued under this clause is to be the volume of the cancelled access licence share component.

cl 46: Subst 2006 (593), Sch 1 [21].

47 Rules for conversion of access licence category

(1)  This clause relates to dealings under section 71O of the Act.

(2)  Dealings that result in conversion of an access licence of one category to an access licence of another category are prohibited in these groundwater sources.

cl 47: Am 2006 (593), Sch 1 [22].

48 Rules for interstate access licence transfer

(1)  This clause relates to dealings under section 71U of the Act.

(2)  Dealings that result in an interstate access licence transfer into or out of these groundwater sources are prohibited.

cl 48: Am 2006 (593), Sch 1 [23].

49 Rules for water allocation assignments between water sources

(1)  This clause relates to dealings under section 71T of the Act.

(2)  Dealings that assign water allocations between an access licence in one of these groundwater sources and an access licence in another of these groundwater sources may be permitted only if:

(a)  the total water allocations credited to all access licences in the groundwater source to which the water allocation is assigned remains below the extraction limit of that groundwater source established in clause 27, as amended by clause 28, or

(b)  the assignment would not result in the total extraction of credited water allocations 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, or otherwise.

(3)  Notwithstanding subclause (2), water allocations may not be assigned from an access licence in Zone 1,2 or 6, to an access licence in Zone 3, 4 or 5.

Note—

Dictionary

The following definitions apply to this Plan in addition to the definitions set out in the Act:

abandoned (work) refers to a water supply work (bore) that is no longer being used.

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.

Note—

An available water determination gives rise to a water allocation that is credited to a water allocation account for each licensed holder.

bedrock is the solid rock underlying unconsolidated sediments such as the soil and weathered rock. Bedrock is a general term for solid rock that lies beneath soil, loose sediments, or other unconsolidated material.

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 that proportion of the long term average annual recharge and storage which can be extracted each year without causing adverse impact on the environment or groundwater users, including landholders exercising basic rights.

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.

groundwater is water that occurs beneath the ground surface in the saturated zone.

long term average storage component is the volume of water in the aquifer less the combined average annual recharge and requirements for basic landholder rights at the commencement of this plan, and exceeds the requirements and supplementary water access provided for in this Plan.

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.

sandstone is sedimentary rock formed by the consolidation of sand grains, the sand component is often predominantly quartz and cemented by a fine grained matrix.

share component is the share component of an access licence.

unconsolidated alluvial aquifers are formed from sediments deposited by the action of flowing water in particular along river beds and floodplains, but not including lakes and seas.

water year is a 12 month period from 1 July to 30 June.

Appendix 4 Rules for determining History of Extraction

(Clause 25C (5))

Rule 1

The history of extraction for each entitlement is calculated separately, irrespective of ownership.

Rule 2

When meter failure has prevented the measurement of actual extraction, extraction will be estimated on the basis of:

(a)  the extraction that was estimated at the time of meter failure held on record by the Department, or

(b)  pump running times held on record by the Department, or

(c)  areas of crops grown and water usage for similar crops.

Rule 3

Estimates made under Rule 2 will be capped at licensed access to water for the entitlement for the year in question.

Rule 4

Where non-volumetric entitlement have been converted to volumetric entitlement during or after the period being used to calculate HOE, any relevant historical extraction or other data used in converting the entitlements will be used to calculate HOE.

Rule 5

In the event of zero or reduced extraction resulting from bore failure the year in which the bore failed will be excluded in calculating HOE.

If a licence holder substantiates a case that the failure of a bore had a greater impact on extraction in the water year following bore failure, then this year rather than the year in which the failure occurred, will be the year excluded.

The licence holder must provide documented evidence of the bore failure.

Rule 6

Failure of associated bore equipment (eg motor, gearbox etc) will not be considered bore failure for the purpose of calculating HOE.

Rule 7

Reduced levels of extraction from a bore due to lower aquifer levels will not be considered bore failure for the purpose of determining HOE.

Rule 8

In the event of lower extraction resulting from crop failure no allowance will be made in calculating the HOE.

Rule 9

Water extracted pursuant to a temporary transfer of entitlement will be accounted in the HOE of the seller or transferor.

Rule 10

Where properties have been amalgamated, all extraction prior to amalgamation will be combined and together with extraction occurring after amalgamation will be used to calculate HOE.

Rule 11

When new entitlements have been created due to subdivision, extractions under the original entitlement will be apportioned to each new entitlement in proportion to the entitlement at the commencement of the plan and together with extraction occurring after subdivision will be used to calculate HOE.

Alternately, where all the new entitlement holders unanimously agreed, extraction under the original entitlement will be calculated for each bore licence and together with extraction occurring after the subdivision will be used to calculate HOE.

Rule 12

Where extractions have not been metered extraction will be assessed on the basis of (in priority order):

(a)  any relevant historical extraction data used in converting non-volumetric entitlement to volumetric entitlement,

(b)  recorded pump usage hours if available, and

(c)  areas of crops grown and water usage for similar crops each year.

Rule 13

Where an entitlement holder is unable to or does not provide information on which to base an assessment for a year the extraction for that year will be will be assessed as zero megalitres.

Rule 14

All extractions that a licence holder ‘carried over’ and/or ‘borrowed’ that were in accordance with management rules applying at the time will be included as extraction for determining history of extraction.

Rule 15

Metered extraction will first be allocated to:

(a)  groundwater only extraction capped at the allocation for that year, then,

(b)  conjunctive groundwater allocation (where applicable) capped at the conjunctive groundwater entitlement for that year, then.

The sum of extraction from groundwater only entitlement and conjunctive groundwater entitlement will be used to calculate the HOE. Any remaining extraction will not be used to calculate HOE.
