1.0 Introduction

1.1 Purpose of this report This Assessment of Effects on the Environment (AEE) supports resource consent applications by New Zealand Defence Force (the applicant), for the Change to Conditions of existing resource consent CRC143416 to include groundwater take and use from a new bore, bore M36/XX1, at Burnham Military Camp, Selwyn. This report contains applications for a change of consent condition to resource consent CRC143416, under Section 127 of the Resource Management Act 1991 (RMA). This report sets out the proposed changes to CRC143416 and an assessment of the environmental effects of the changes. As the changes are a minor alteration with the addition of bore M36/XX to be included within Condition 2 and there are no changes proposed to the volume of water abstracted; the changes are within the scope of the original consent and can be considered under Section 127 of the RMA. This report addresses the resource consent requirements and satisfies Section 88 of the RMA. Section 88 requires that an application for resource consent includes, in accordance with Schedule 4, an AEE in such detail as corresponds with the scale and significance of the effects that the activity may have on the environment.

1.2 Background New Zealand Defence Force (NZDF) operates Burnham Military Camp (the Camp) in Selwyn District. NZDF currently holds two resource consents to abstract groundwater for use at the Camp. CRC143414 allows for the take and use of groundwater from bores M36/2692 and M36/0078 for defence purposes and irrigation of the Golf Course, Burrows Field, Coronation Park and the worm farm at a volume not exceeding 4,536 cubic metres in any period of seven consecutive days. CRC143416 allows for the take and use of groundwater from bore M36/2694 with a volume not exceeding 6,125 cubic metres in any seven day period and bores M36/2693, M36/0008, M36/5777, M36/2692 and M36/0078 with a combined total volume not exceeding 18,375 cubic metres in any seven day period. Both consents are contained in Appendix A. In June 2018 a review of the Camp’s water supply was undertaken by AECOM. The report concluded that the general consensus of research on groundwater resources on the Canterbury Plains suggests that groundwater levels are decreasing. The primary factor considered to be affecting the availability of groundwater resources is climate and climate change. The general trend of the available climate change predictions is that the future may see increases in temperature, evaporation and drought, which would lead to reduced recharge rates to the shallow aquifer providing supply to the Camp. Furthermore, increased temperatures, evaporation and drought would also increase irrigation demand by existing users. As a result, the groundwater resources on the Canterbury Plains are predicted to decrease in the future due to climate change. Therefore, meeting the Camp’s demands may become an issue in future. Burnham Military Camp is zoned Rural Outer Plains in the Selwyn District Plan. It has a designation by the Minister of Defence (DE1) for Defence Purposes – Burnham Military Camp. The Camp has been operating from this location since 1923. A number of military units are hosted onsite, and the Camp provides a variety of training from basic to pre-deployment. Facilities on the Camp include workshops, garages, hangars, offices, accommodations, and training equipment. The Camp also has heritage items (H206, H204, H203, H202), protected trees (T20, T19) in the Selwyn District Plan, shops, residential areas, a childcare facility, a kindergarten, a golf course and leased farm land on site. The Camp population fluctuates depending on operational commitments. The current population is estimated to be approximately 1,100, with an additional day working population of 900.

2.0 Description of the Environment

2.1 The Site The extent and location of the site is shown in Figure 1. The site is located about 6 km southwest of Rolleston on State Highway 1 / Main South Road. The land is owned by Her Majesty the Queen and spans over seven land parcels: RES 1159, Pt RES 1160, RES 1176, Pt RS 13523, RS 41213, Pt RES 1636, and Pt RES 1636.

Figure 1: Burnham Military Camp Location (Camp boundary in blue)

2.2 Groundwater Burnham Military Camp falls within the Selwyn-Waimakariri allocation zone of the Canterbury Plains, which consists of a glacial outwash and reworked deposits of the Waimakariri River. The thickness of gravels ranges from approximately 300 m to 600 m and hosts significant quantities of good quality groundwater. Groundwater flows in a general southeast direction from the foothills to the coast. Flow patterns are controlled by the degree of sorting of deposits and the presence of old buried river channels and other preferential flow paths. Bore depths in the Selwyn-Waimakariri zone range from less than 5 m deep adjacent to surface waterbodies and near the coast to greater than 200 m on the inland plains. The Camp has taken water from bores within the camp since mid-1966 and its current groundwater supply is consented by Environment Canterbury (ECan) under resource consents CRC143414 and CRC143416. Both of these consents expire 31 January 2035. The current bores draw from the shallow aquifer below the Camp at depths of between 24.3 and 54.9 m below ground level. ECan’s Age and Source of Canterbury Plains Groundwater Report (Report No. U02/30) dated April 2002 suggested the shallow groundwater system around Burnham is predominately recharged by infiltration of rainfall in the area of the Camp and the inland catchment zone. Analysis of groundwater residence times of the Camp’s bores was completed by GNS Science in March 2014 and showed groundwater had a mean age of 50 to 60 years.

The Well interference and Aquifer Test (Appendix D) concluded that the aquifer tested through the new bore, M36/XX, at a depth of 200 m, is considered likely to be leaky based on the conceptual hydrogeological model. Aquifer thickness was also assumed to be 10 m. The depth of the underlying aquitard is unknown, and due to the heterogeneity of the aquifer system and lack of boreholes drilled beyond 200 m within the vicinity of the bore in question, the thickness was inferred based on the distance between impermeable lenses above the aquifer M36/XX. Groundwater use in the wider environment is used predominantly for potable supply and irrigation and bores are predominately between 24 and 55 m deep, with a few deeper bores between 102 and 168 m deep. Current resource consents (CRC143414 and CRC143416) name six bores which all are located within the Camp (Figure 2).

Figure 2: Bore Locations (CRC143414 blue, CRC143416 red) CRC143414 utilises two bores; M36/2692 and M36/0078 for a combined seven day limit of 4,536 cubic metres (Table 1). CRC143416 has six bores, bore M36/2694 with a seven day volume limit of 6,125 m3 and the remaining five bores have a combined total seven day volume limit of 18,375 m3 (Table 2). The combined maximum volume from all bores, including bores consented for irrigation take, is on average 3,500 m3/day. The resource consents require that the flow rate from each bore must be logged at one-minute intervals.

Contamination from agricultural land is caused by nitrogen sources including stock urine patches, septic tank effluent, animal feed pads and fertilisers. This is a likely contributor to the nitrate loads in the area. As the Camp currently draws water from a semi-confined aquifer, there is a long lag time for effects to show up in the groundwater, such that the current nitrate levels may be a result of the application rates of nitrate some time ago. Thus the full impact of the present land use in the catchment may not be reached for decades. ECan has been working with the Selwyn Waihora Zone community to mitigate the increasing nitrate trends and set limits on water quality and nutrient losses. ECan’s Technical report to support water quality and water quantity limit setting process in Selwyn Waihora Catchment, Predicting consequences of future scenarios, Groundwater quality describes ECan workshopping with the Selwyn Waihora Zone Committee and the wider community to identify potential solutions involving changing land use within the zone. The potential solution negotiated from the workshops was then input into a groundwater quality model, and the results predicted that under this scenario, nitrogen concentrations in groundwater and surface water would still increase compared to currently measured concentrations, but those increases would not be quite as great as they would be under the 2011 land use configuration. Thus, work is ongoing. The lag time between nitrate being discharged to the soil and it reaching the water table means the benefits of any strategies ECan manages to implement would only be realised in the medium to long term. It is likely that nitrate levels at the Camp would reach the maximum acceptable value before any benefits from these strategies in the area would show effect. The Camp conducts routine monitoring of its water supply system, undertaken by the facilities management contractors. A combined automated continuous monitoring and manual sampling program is used to monitor required parameters to allow operation of the water supply system and demonstrate Drinking Water Standards for New Zealand compliance. The Camp’s potable water supply treatment consists of, chlorine disinfection with chlorine gas and fluoride dosing with hydrofluorosilicic acid. The chemicals are dosed directly into incoming pipes at both storage towers. Chlorine dosing is an automatically adjusted system, while the fluoride dosing \\nzchc1fp001\Projects\605X\60586487\400_TECH\431_DESIGN\04. Detailed Design\05.

system is manually adjusted. The hydraulic retention times in the towers provides the required minimum 30 minute contact time for chlorine disinfection. Chemical supplies are stored in bunded tanks in secure storage buildings adjacent to the water towers. The treatment systems are connected to backup power supplies (standby generators).

2.3 Soil The site is listed on the Listed Land Use Register (LLUR) which identifies four potential HAIL activities (F7, F4, A10 and F8). In 2017, in conjunction with ENGO Ltd2, the NZDF conducted a detailed assessment of potential, historic and current, HAIL activities within the Camp. The report identified a number of HAIL activities and mapped their locations. Eight HAIL categories were identified (A10, A17, B, C, E, F, G, and I). The majority of identified HAIL activities within the Camp were classed as low priority. From the study no HAIL activities were identified in the location of bore M36/XX and historic aerial imagery indicates that the area has been a field since at least the 1940s. The structure to the northeast corner appeared from the 1960s onwards and buildings in the southeast corner of the field appeared from the 1980s onwards. On the basis of the available information, the site could be considered to be a HAIL site. However, it is a low likelihood that soil in the immediate vicinity of bore M36/XX’s location has significant contamination. ECan were engaged on November 29, 2018. Conor Parker from the ECan Contaminated Sites team responded, confirming that the site of the bore M36/XX would not be regarded to be within a HAIL and it is unlikely to be affected by the nearby hazardous goods stores (evidence in Appendix B).

3.0 Description of Proposed Activities

3.1 Overview NZDF foresees a maximum increase in population from 2,000 to 2,500 personnel, which is estimated to increase future water demand by approximately 30%. Based on current consent limits and groundwater levels, the existing supply system should be able to meet this increased demand as-is. However, future changes to groundwater resources are expected that would affect the ability of the existing system to meet the projected future demands. The proposed take and use of groundwater from the recently constructed bore M36/XX, which has a depth of 200 m, is proposed to accommodate this foreseen drop in water levels across the Canterbury plans. This will ensure that the NZDF has adequate water supplies in the future. No increase in the currently consented groundwater allocation limit is proposed.

3.2 Bore M36/XX Bore M36/XX is located north-west of the main buildings, close to the corner of Burdons Road and Ayslesbury Road (Figure 3). The NZTM 2000 coordinates of the bore are approximately E1544278.7 N5171299.3. Details of its information are in Table 3 and the design details are attached in Appendix C.

4.0 Resource Consent Requirements

4.1 Permitted Activities The construction and testing of bore M36/XX is classified as a permitted activity through Rule 5.103 and 5.109 of the LWRP. These are outline and discussed below: Rule 5.103: The use of land, including the bed of a lake or river, for the installation, maintenance and use of a water infiltration gallery (other than a water infiltration gallery used for emergency firefighting purposes), or a bore, other than a bore for hydrological or geotechnical investigation or monitoring, is a permitted activity, provided the following conditions are met: 1. The bore or gallery is installed by a bore driller or bore drilling company that holds a current accreditation under the CRC bore Installers Programme; and 2. The screening of any bore or gallery may only be into a single aquifer or water-permeable zone. During bore installation reasonable and practicable methods shall be used to minimise the risk of interconnection or movement of groundwater between aquifers or water-permeable zones; and 3. Any bore constructed to abstract groundwater is screened to below any minimum water level for the groundwater zone as set out in Section 6 to 15 of this Plan; and 4. Contaminants or water are prevented from entering the top of the bore or gallery or underlying groundwater by: a. covering or capping the bore or the above ground portion of the gallery pipe, when not in use; and b. sealing the exterior of the bore (the annulus) with bentonite or concrete grout from ground level to above the screen or 1 m below ground level, whichever is the lesser; and c. sealing the bore-head or above ground portion of the gallery pipe at ground or pumphouse floor level with a concrete pad of at least 0.3 m radius and 0.1 m thickness which is contoured to slope away from the bore or pipe; and 5. Information on bore or gallery location, bore installation (including bore logs and intended uses), and other relevant information is submitted to the CRC within 20 working days of drilling the bore; and 6. The bore or gallery is not installed on contaminated or potentially contaminated land. ECan does not consider the bore area to be a HAIL site (Appendix B) and the construction of the bore complied with the permitted conditions. Rule 5.109: The taking of water from groundwater for the purposes of carrying out bore development or pumping tests, or incidental to hydrological or geotechnical investigations, and the associated use and discharge of that water is a permitted activity, provided the following conditions are met: 1. The take continues only for the time required to carry out bore development or a pumping test and in any event, the taking does not exceed 120 hours within any 14 day period and total no more than 10 days in any consecutive 12 month period per bore; and

2. Any bore development or pumping test is carried out in accordance with Schedule 11; and 3. bore development or pumping tests shall cease upon notification that the pumping may be preventing access to any: a. community drinking water supply; or b. private drinking water supply, except any supply located on the property the test is being carried out on; and 4.At the point and time of any discharge to surface water, the rate of flow in the river or artificial watercourse is at least five times the rate of the discharge; and 5.The concentration of total suspended solids in the discharge does not exceed: a. 50g/m3 to any spring-fed river, Banks Peninsula river, or to a lake; or b.100g/m3 where the discharge is to any other river or to an artificial watercourse. The testing has been completed in accordance with Schedule 11 and therefore complied with all conditions in rule 5.109. The report is attached in Appendix D.

4.2 RMA Section 127 – Change of Consent Condition CRC143416 authorises the take and use of groundwater. The proposed change to conditions is limited to the following amendments to Condition 2 (deletions shown with a strike through and additions underlined): 2. The rate and seven day volume at which water is taken from bores M36/2694, M36/2693, M36/0008, M36/5777, M362692, M36/0078, M36/XX shall not exceed the rates and volumes in the table below: Combined Bore Seven Day Bore Bore Depth Map Rate of Seven Day Diameter Volume Reference (m) Reference take (L/s) Volume (mm) (m3) (m3) M36/2694 150 24.3 NZMS 260 27 6,125 6,125 M36:5319- 3232 M36/2693 200 54.9 NZMS 260 27 16,329 18,375 M36:5435- 3269 M36/0008 152 46 NZMS 260 29 8,467 M36:5420- 3300 M36/5777 100 40 NZMS 260 19 11,491 M36:5343- 3252 M36/2692 250 47.8 NZMS 260 37 4,536 M36:5469- 3279 M36/0078 250 47.9 NZMS 260 20 4,536 M36:5544- 3280 M36/XX 250 200 NZMS 260 30 18,375 M36:XX

Section 127 of the RMA allows for the holder of a resource consent to apply for changes of conditions: (1) The holder of a resource consent may apply to a consent authority for a change or cancellation of a condition of the consent, subject to the following: \\nzchc1fp001\Projects\605X\60586487\400_TECH\431_DESIGN\04. Detailed Design\05. Planning\Water permit change\Burnham Military Camp Water Permit -s127 AEE -FINAL.docx Revision 2 – 07-Jun-2019 Prepared for – New Zealand Defence Force – Co No.: N/A AECOM Burnham Military Camp Water Permit - Change of Consent Condition – Assessment 9 of Effects on the Environment

(a) the holder of a subdivision consent must apply under this section for a change or cancellation of the consent before the deposit of the survey plan (and must apply under section 221 for a variation or cancellation of a consent notice after the deposit of the survey plan); and (b) no holder of any consent may apply for a change or cancellation of a condition on the duration of the consent. (2) [Repealed] (3) Sections 88 to 121 (sections relating to resource consent applications) apply, with all necessary modifications, as if— (a) the application were an application for a resource consent for a discretionary activity; and (b) the references to a resource consent and to the activity were references only to the change or cancellation of a condition and the effects of the change or cancellation respectively. (3A) If the resource consent is a coastal permit authorising aquaculture activities to be undertaken in the coastal marine area, no aquaculture decision is required in respect of the application if the application is for a change or cancellation of a condition of the consent and does not relate to a condition that has been specified under section 186H(3) of the Fisheries Act 1996 as a condition that may not be changed or cancelled until the chief executive of the Ministry of Fisheries makes a further aquaculture decision. (4) For the purposes of determining who is adversely affected by the change or cancellation, the consent authority must consider, in particular, every person who— (a) made a submission on the original application; and (b) may be affected by the change or cancellation. CRC143416 was itself a Section 127 application that replaced CRC020462. We do not believe that either of these applications were processed on a limited notified or notified basis, so there were no submissions to the original application. This means that determining those who may be adversely affected for this application is restricted to the those affected by the change to Condition 2. For the purposes of considering who may be adversely affected by the proposal, and since there are no changes to the overall volume of take, it is solely consideration of whether a combined take at varying depths will significantly affect neighbouring bore owners. This has been considered in the Well Interference Assessment included in Appendix D where it was concluded that the impact of the proposed water take on the surrounding bore users is likely to be less than minor . Section 127 requires the application to be considered as a discretionary activity. Case law has established that Section 127 may be used for changing conditions provided that the application is not for a materially different activity (i.e. increase in scope). The question of whether an activity is materially different is one of fact and degree to be determined in the circumstances of the case. In this case a change in conditions is considered appropriate as: • There is no change in the currently consented groundwater take volume seven day limit; • Groundwater take and use from bore M36/XX will be manged within the already allocated 18,375 m3 combined seven day volume limit; • There are no changes to proposed to the use of water taken under the existing consent; and • It is considered that the impact of the proposed water take on the surrounding bore users is likely to be less than minor.

5.0 Assessment of Effects on the Environment

5.1 Introduction To enable NZDF to take and use groundwater from bore M36/XX within Burnham Military Camp and manage its use within the already consented allocation limit then a change in consent conditions is required under the RMA. Section 104 of the RMA requires the consent authority, when making a decision on a resource consent application, to have regard to the actual and potential effects on the environment of allowing an activity. Under Section 127 of the RMA the consideration of the effects is limited to the effects of the change to Condition 2 rather than a reassessment of the activity as a whole. The environmental effects of the proposed changes are assessed in this section of the report.

5.2 Positive Effects Currently resource consent CRC143416 has rate and daily volume restrictions and names six bores in which groundwater can be taken and used within the prescribe volume limits and rates. By allowing groundwater to be taken and used from the new bore, bore M36/XX without increasing the current volume restrictions, NZDF can futureproof its water requirements without increasing volume limits. The addition of bore M36/XX will allow further flexibly of groundwater take to be spread out between bores and aquifers. This will allow for even more flexible management of bores M36/2694, M36/2693, M36/0008, M36/5777, M362692, M36/0078 and reduce pressure on shallower aquifers. Futureproofing of Burnham Military Camp against climate change will allow for the NZDF to continue operating effectivity from its current location.

5.3 Surface Water Taking groundwater from bores that are hydraulically connected to any surface water could affect flows in the water body. There are no hydraulically connected surface water bodies at the site as the Selwyn River is located approximately 5.7 km southwest of the Camp and flows east into Lake Ellesmere Te Waihora, which is approximately 14.3 km southeast of the site. The currently consented bores draw water from depths between 24 and 55 m and their associated aquifers are semi-confined. However, bore M36/XX would be drawing water from depths of 200 m and is considered a leaky confined aquifer. As a result of including bore M36/XX into the already consented volume limit would allow more flexibility to draw from a range of aquifers. This in turn would likely have a positive effect on surface water bodies as less water could be taken from the higher aquifers and these aquifers would be able to recover faster as well as any flow on effects to the surface water body. Overall, as there is no change in the currently consent water volume limit, the effects on surface water bodies is considered to be less than minor.

5.4 Groundwater levels and surrounding groundwater users The abstraction of groundwater creates a drawdown cone that extends laterally from the pumping bore, and may result in a lowering of groundwater levels in neighbouring bores. Such lowering may prevent existing users from taking their authorised or permitted amount and may also result in increased costs for such users through having to lower their pump, changing from a surface to submersible pump or by using more electricity to abstract water. The currently consented bores are between 24 and 55 m in depth, which access groundwater from shallower, semi-confined or unconfined, aquifers. Bore M36/XX is over 100 m deeper than the currently consented bores and is likely to be a leaky confined aquifer.

The Well Inference and Aquifer Test Report is attached in Appendix D, and is summarised below. The following tests were completed: • Step Drawdown Aquifer Test, which was analysed using analytical modelling software AQTESOLV. The Hantush-Jacob (1955) solution for leaky confined aquifers and the Thesis (1935) solution for confined aquifers were applied to acquire aquifer parameters;

• Constant Discharge Aquifer Test, to assess well interference when water levels in nearby observation wells are monitored. Two bores (M36/2693 and M36/7712) located within the vicinity of the new water supply bore were monitored throughout the test period. and; • Well interference assessment was conducted using the online WQN10 tool. In conclusion the report found that vertical leakage is expected due to the semi-confined nature of the aquifer and the Hantush-Jacob (1955) solution is considered more representative of the actual aquifer transmissivity. Maximum displacements of less than 10 cm were observed in the observation wells over 48 hours of pumping at an average flow rate of 30.8 l/s. This is considered to be minor and suggests there is limited to no connection between the pumping well and changes to groundwater levels in the adjacent wells over the duration of the test. This minor observed trend in groundwater levels could be attributed to background groundwater fluctuations from recharge sources rather than a direct result of the testing undertaken. A total of 27 wells were identified within 2,000 m of bore M36/XX. The WQN10 tool suggested none of these existing wells will exceed the allowable 20% of available drawdown as per Schedule 12 of the Land and Water Regional Plan.

5.5 Effects of inefficient take on other groundwater users Water is taken from the Burnham Camp site only when required to meet drinking water demand for the Camp. The rate of take, annual volume restrictions and site of use conditions are mitigation measures that ensure groundwater is taken and used efficiently. The proposed addition of bore BX23/0903 will accommodate for a foreseen drop in water levels across the Canterbury plans and ensure that the NZDF has an adequate water supply in the future. No increase in the currently consented maximum water take limit is proposed.

5.6 Effects of take on aquifer stability and seawater intrusion The bore log (Appendix A of the Well Interference and Aquifer Test Report (Appendix D). Showed that the area consists almost entirely of gravels, cobbles and some boulders, with minor components of sand, and are thus not expected to subside or compress when de-watered. With reference to Environment Canterbury technical report R04/18 (Seawater Intrusion Guidelines)3, all wells within 2000 m of the coast that have a proposed pumping rate of greater than 30 l/sec should be considered. Given that bore M36/XX is located approximately 14.3 km from Lake Ellesmere/Te Waihora and a further 15 km from the coast the abstraction of water from the subject bore is unlikely to result in seawater intrusion occurring. There is no change to the overall volume of the take, and the greater depth of the new bore is unlikely to result in a change to the saline interface at the coast given the separation distance from the coast.

5.7 Groundwater quality Bore M36/XX has been constructed and has been tested in accordance with the permitted activity conditions of rule 5.103 and 5.109 in the LWRP. The addition of bore M36/XX to resource consent CRC143416 will not have measurable effects on groundwater quality. The taking and use of groundwater will remain within the currently consented limits and within the purpose of the current consent.

5.8 Management of Contaminants in Soil As discussed in Section 2.3, the Camp is identified on LLUR as a HAIL site and no evidence of HAIL activities occurring on bore M36/XX’s site were found. ECan were engaged on 29 November 2018 (Appendix B) and confirmed that the site of bore M36/XX would not be regarded to be within a HAIL and it is unlikely to be affected by the nearby hazardous goods stores. Bore M36/XX has been constructed and will be tested to the permitted conditions of rule 5.103 and 5.109 in the LWRP and contamination to soil from the operation of this bore is minimal.

5.9 Tangata whenua values There are no Silent File Areas, Treaty of Waitangi Settlement Areas or sites of cultural significance within the site of the proposed works or Burnham Camp. The Mahaanui Iwi Management Plan reflects the Ngāi Tahu values and policies in regard to natural resource management in Canterbury. The issues and policies relevant to the proposed activity include: • Issue of Significance WM3 and related polices in the priorities for use based on Ngai Tahu values. • Issue of Significance WM8 and related polices in the over allocation of freshwater resources. This s127 application, with the addition of bore M36/XX is not increasing the already consented maximum volume limit. The use of bore M36/XX will enable Burnham Camp to future proof its water supply without increasing its total allocation needs. On this basis the effects on tangata whenua values are expected to be no less than minor.

5.10 Summary of Effects The addition of bore M36/XX to CRC143416, Condition 2, to enable the take and use of groundwater from this bore within the currently consented volume limits as discussed above is overall considered to have no more than minor effects on the environment.

6.0 Statutory Assessment

6.1 National Environmental Standards National Environmental Standards for Assessing and Managing Contaminants in Soil to Protect Human Health (NES-Soil). NES-Soil sets out regulations for the management of sites where HAIL activities have occurred in the past. As discussed in Section 2.3, the site of bore M36/XX is not regarded as HAIL and therefore the NES-Soil does not apply. The proposed addition of a bore to enable the take and use of groundwater from a lower aquifer require assessment under the National Environmental Standard for Sources of Human Drinking Water (NES-Drinking Water). As the NES-Drinking Water purpose is to set requirements for protecting sources of human drinking water from becoming contaminated. Water source is a natural water body such as a lake, river or groundwater that is used to supply a community with drinking water and applies to sources of water before it is treated and only sources used to supply human drinking water. Groundwater that is used within the Camp is treated to New Zealand Drinking water Standards as discussed in Section 2.2.1. Also, as discussed in Section 5.5, the bore was designed and will be tested in accordance with permitted rules in the LWRP (Section 4.1).

6.2 National Policy Statements The National Policy Statement for Freshwater Management (NPS-Freshwater) sets out the objectives and policies for freshwater management under the RMA. For this change of condition, the follow objectives regarding water quantity are relevant: • Objective B1 relates to safeguarding the life supporting capacity and ecosystem process of freshwater and the sustainable management of taking, using, damming or diverting fresh water, • Objective B2 and Policy B5 relates to the avoidance of any further over-allocation of fresh water, • Objective B5 relates to enabling communities to provide for their economic well-being within limits, The proposed addition of bore M36/XX to CRC143416, will not increase NZDF’s current water allocation limits. It will allow the dispersion of water take and enables better management of high aquifers, while providing for the economic grow and future resilience’s of the Burnham community and the NZDF.

On this basis, the proposed change in condition will not impact on ECan’s ability to set and meet environmental limits and is therefore consistent with the NPS-Freshwater.

6.3 Regional Policy Statement The Canterbury Regional Policy Statement (CRPS) gives an overview of the significant resource management issues facing the region. The purpose of the CRPS is to set out objectives, policies and methods to resolve those resource management issues and to achieve the integrated management of the natural and physical resources of the Canterbury region. The most relevant to this application is Chapter 7 which relates freshwater quality and quantity and Chapter 5 which relates to land-use and infrastructure. The following objectives and policies are of relevance to the application: • Objective 5.2.2 and 7.2.1 both enable people and communities to the extent that it promotes sustainable management. • Objective 7.2.3 to safeguard intrinsic values of waterbodies • Objective 7.2.4, Policy 7.3.1 and 7.3.4 to integrated sustainable management and identify, preserve, maintain and improve natural character values of freshwater • Policies 7.3.4, 7.3.5, 7.3.6 and 7.3.7 relate to avoiding, remedying or mitigating adverse effects of land uses on water quality and water quantity. The proposed activity is considered to have no more than minor effects on the quality or quantity of groundwater, while enabling people and the community at Burnham to continue its operations into the future. Therefore, the use of bore M36/XX is consistent with the CRPS.

6.4 Part 2 Assessment The purpose of the RMA, as stated in Section 5 of the Act, is to promote the sustainable management of natural and physical resources. The purpose is support by the principles contained in Sections 6-8 of the Act. Section 5: Purpose Sustainable management is defined as in Section 5(2) as follows: …means managing the use, development, and protection of natural and physical resources in a way, or at a rate, which enables people and communities to provide for their social, economic, and cultural wellbeing and for their health and safety while— (a) sustaining the potential of natural and physical resources (excluding minerals) to meet the reasonably foreseeable needs of future generations; and (b) safeguarding the life-supporting capacity of air, water, soil, and ecosystems; and (c) avoiding, remedying, or mitigating any adverse effects of activities on the environment. The use of bore M36/XX will enable flexible management of groundwater at Burnham Military Camp. This flexible management to access a lower aquifer is considered to enable better management of the higher aquifers and reduce their potential over allocation in the future. Therefore, it is consistent with the purpose of the RMA. Section 6: Matters of National Importance On the basis that the activity is occurring in a highly modified environment and not within areas of significant natural or physical value, and any other sensitive sites will be avoided, there are considered to be no matters of national importance affected by the proposed activities. Section 7: Other Matters Section 7 of the RMA outlines other matters which are considered relevant to this application: (a) kaitiakitanga:

(aa) the ethic of stewardship: (b) the efficient use and development of natural and physical resources: […] (c) the maintenance and enhancement of amenity values: (d) intrinsic values of ecosystems: […] (f) maintenance and enhancement of the quality of the environment: (g) any finite characteristics of natural and physical resources: (h) the protection of the habitat of trout and salmon: (i) the effects of climate change: (j) the benefits to be derived from the use and development of renewable energy. These matters have been incorporated into discussions throughout this report. Overall, the use of bore M36/XX is consistent with Section 7 of the RMA. Section 8: Treaty of Waitangi Section 8 requires the principles of the Treaty of Waitangi to be taken into account when managing the use, development, and protection of natural and physical resources. It is considered that, given the volume limits will not increase, the site is not located near a water body or a site identified as significant to iwi and the potential adverse effects are no more than minor, the proposal is consistent with Section 8 matters. Summary The change of conditions to CRC143416 through the addition of bore M36/XX enables the futureproofing of water supply at Burnham Military Camp. It also allows for the ability to better manage take from current bores within high aquifers. Any adverse effects that have been identified will be appropriately avoided, remedied or mitigated. Overall, the project will allow for users to provide for their social, economic and cultural wellbeing while avoiding, remedying or mitigating the effects of doing so. In this regard the project is consistent with the purpose of the RMA.

7.0 Notification Sections 95A to 95E of the RMA set out the requirement for notification of a resource consent application. In particular under section 95A the applicant does not request this application to be public notified and the application is not jointly with an application to exchange recreation reserve land under section 15AA of the Reserves Act 1977. Overall, there are no restrictions for notification in Section 127 of the RMA or within the LWRP. However as discussed in Section 5.0 the effects of the proposed change to Condition 2 is considered to be no more than minor and there are no affected parties as a consequence of this change. With consideration to the above, the application can therefore be processed on a non-notified basis.

8.0 Conclusion The proposed change to CRC143416 is a minor alteration with the addition of bore M36/XX to be included within Condition 2 and no change proposed to the overall consented volume limit. Therefore, the changes are within the scope of the original consent and can be considered under Section 127 of the RMA. The change to CRC143416 proposed in this application will help enable the NZDF to more effectively manage water use at Burnham Military Camp into the future. Retaining the current seven day volume restrictions with the additional option to draw from a deeper aquifer through bore M36/XX will ensure that the NZDF have a greater flexibility to use and sustainably manage groundwater. The assessment of environmental effects concluded that the operation of bore M36/XX will have a no more than minor effect on the environment.

In conclusion the operation and use of bore M36/XX will enable the NZDF to use Burnham Military Camp into the future while avoiding, remedying or mitigating effects on the environment. Overall, the proposed activities are considered to be consistent with the purposes of the RMA as they promote the sustainable management of natural and physical resources.

1.0 Introduction

1.1 Scope AECOM New Zealand Ltd (AECOM) were approached by the New Zealand Defence Force (NZDF) to undertake an aquifer test report and well interference assessment associated with their new water supply bore at Burnham Military Camp to meet the requirements set out in schedule 11 and 12 of the Canterbury Land and Water Regional Plan (ECAN, 2019) and support their resource consent application requirements.

1.2 Testing completed The testing and data collection were undertaken by East Coast Drilling Ltd, who also drilled and installed the new bore. A step-test on the new bore was undertaken on the 15th April 2019. Thereafter, a constant discharge test was conducted from the 15th April 2019. Water levels in two nearby wells (M36/2693, M36/7712) and the atmospheric pressure were monitored during the testing period. AECOM field staff were not involved in the field testing and collection of the data. Raw data from these tests was supplied to AECOM from East Coast Drilling Ltd for the purpose of this assessment.

1.3 Conceptual hydrogeological model The Canterbury Plains were formed during a climatic cycle of warming and cooling that resulting in sea level rise and fall. Inland coastal migration during interglacial periods led to the deposition of marine and estuarine sediments beneath Christchurch. Alluvial systems deposited glacial outwash gravels on top of these finer sediments during glacial periods. This cycle formed a well-defined coastal aquifer system with flowing artesian conditions in the deep coastal confined aquifers. Further inland, the sub- surface geology consists mostly of glacial outwash gravel deposits formed by the major alpine rivers over the Quaternary period. However, there is evidence that suggests a multi-layered aquifer system also exists inland as the gravels are separated by lenses of fine-grained material deposited during interglacial periods (URS, 2009). The Burnham Military Camp is located in the Central Plains, between the Rakaia and Waimakariri Rivers. The smaller Selwyn River flows past the southernmost extent of Burnham, approximately 5 km from the military camp. Regional groundwater flow moves in a south-easterly direction towards the Banks Peninsula. Burnham is situated outside of Christchurch and the confined aquifer system, so the sub-surface geology consists mostly of quaternary gravels with lenses of fine impermeable sediments. The aquifer system is recharged by rainfall infiltration on the plains, as well as from the surrounding rivers. Permeable gravels and buried river conduits facilitate water migration from the rivers into the aquifer system. Sub-surface geology beneath Burnham is reflected in the bore log of the newly installed water supply well as displayed in Appendix A. The bore log consists almost entirely of gravels, cobbles and some boulders. Minor components of sand and to a lesser degree silts and clays are present within the lithological profile. The gravels are separated by thin lenses of impermeable clay. These lenses are not horizontally extensive. Hence, the screened aquifer can be considered leaky confined, or semi- confined.

2.0 Step Drawdown Aquifer Test A step drawdown test is a single well test designed to determine aquifer parameters and test the efficiency of the well. It involves pumping the well at increasing rates and measuring the resulting drawdown.

\\NZCHC1FP001\Projects\605X\60586487\400_TECH\Well Interference Assessment\Report\Burnham Well Interference Assessment Report Rev 2.docx Revision – 16-May-2019 Prepared for – New Zealand Defence Force – ABN: N/A AECOM Burnham Potable Water Supply Upgrade Project 2 Well Interference and Aquifer Test Report

2.1 Step test procedure Pumping began at approximately 8:30 am on the 15th April 2019. A barometric logger was set up outside the well to record atmospheric pressure. Water pumped from the well was discharged through above-ground pipework attached to the well with an in-line flowmeter installed a few meters from the well. This pipework fed into a hose which extended over 100 m, beneath a road and then discharged through a perforated pipe onto an NZDF owned field. Water was pumped at an initial rate of 15 l/s, increasing by 5 l/s every hour up to a maximum rate of 30 l/s. Thereafter, pumping ceased to allow for a period of recovery. Details of the step test are provided in Table 1. Table 1. Summary of step test Step Pumping rate (l/s) Start time End time Maximum Drawdown (m) Step 1 15 08:30 9:30 5.6 Step 2 20 09:30 10:30 8.1 Step 3 25 10:30 11:30 11.0 Step 4 30 11:30 12:30 13.4 Recovery 0 12:30 14:00 2.2

The barometric loggers provided absolute pressure within the well. This is a sum of the pressure applied from the atmosphere as well as the water column. Thus, it was necessary to remove barometric pressure from the dataset to acquire the actual water level above the transducer. The depths that the pressure transducers were set within the well were not recorded. However, displacement within the well was still able to be calculated. Barometric corrections were applied to all data to remove water level fluctuations resulting from changes in atmospheric pressure.

2.2 Step test analysis The displacement in relation to the static water level during the step test is displayed in Figure 1.

\\NZCHC1FP001\Projects\605X\60586487\400_TECH\Well Interference Assessment\Report\Burnham Well Interference Assessment Report Rev 2.docx Revision – 16-May-2019 Prepared for – New Zealand Defence Force – ABN: N/A AECOM Burnham Potable Water Supply Upgrade Project 3 Well Interference and Aquifer Test Report

Figure 1. Step test - pumping well displacement Step test data was analysed using analytical modelling software AQTESOLV. The Hantush-Jacob (1955) solution for leaky confined aquifers and the Theis (1935) solution for confined aquifers were applied to acquire aquifer parameters. The software allows for automatic curve matching using nonlinear weighted least-squares regression. Assumptions taken include: · Aquifer has infinite areal extent · Aquifer is homogeneous, isotropic and of uniform thickness · Pumping well is partially penetrating · Aquifer is confined · Aquifer is leaky (Hantush-Jacob solution only) · Flow is unsteady · Water is released instantaneously from storage with decline of hydraulic head · Diameter of pumping well is small, therefore storage in the well can be neglected · Aquitards have infinite areal extent, uniform vertical hydraulic conductivity and uniform thickness · The flow is radial towards the well during pumping · All changes in the water level are due to the pumping test alone · Aquitards are overlain or underlain by an infinite constant-head plane source · Aquitards are incompressible (no storage) · Flow in the aquitards is vertical (Hantush-Jacob solution only)

Aquifer thickness was also assumed to be 10 m. The depth of the underlying aquitard is unknown, and due to the heterogeneity of the aquifer system and lack of boreholes drilled beyond 200 m within the vicinity of the bore in question, the thickness was inferred based on the distance between impermeable lenses above the aquifer.

\\NZCHC1FP001\Projects\605X\60586487\400_TECH\Well Interference Assessment\Report\Burnham Well Interference Assessment Report Rev 2.docx Revision – 16-May-2019 Prepared for – New Zealand Defence Force – ABN: N/A AECOM Burnham Potable Water Supply Upgrade Project 4 Well Interference and Aquifer Test Report

Aquifer parameters as calculated in AQTESOLV are summarised in Table 2. Table 2. Aquifer parameters determined from analytical modelling of step test displacement data Parameter Theis (1935) Solution Hantush – Jacob (1955) Solution Transmissivity (m2/day) 354 254 Storativity 2.7×10-5 4.8×10-3 Hydraulic Conductivity 35 25 (m/day)

Specific Storage (m-1) 4.8×10-4 2.7×10-6 Leakage factor (m) 2275

The Hantush – Jacob (1955) solution is considered to provide a more representative transmissivity value as it accounts for vertical leakage through the overlying aquitard. Vertical leakage is expected due to the semi-confined nature of the aquifer.

3.0 Constant Discharge Aquifer Test Constant discharge tests can be used to assess well interference when water levels in nearby observation wells are monitored. Two bores located within the vicinity of the new water supply bore were monitored throughout the test period. Details of these bores are listed in Table 3. Table 3. Water supply bore and observation well details Well Purpose in test Depth (m) Diameter Screen Initial water Distance from (mm) (mm) level (m bgl) pumping well (m) New bore Pumping well 198.0 300 200 26.3 N/A M36/2693 Observation 54.90 200 - Unknown 1,845 M36/7712 Observation 162.0 300 200 Unknown 225

3.1 Constant discharge test procedure The constant discharge test was undertaken on the 15th April 2019 in the afternoon following the recovery period of the step test. The target flow rate was 30 l/s, which was maintained for 48 hours. Details of the test are summarised in Table 4: Table 4. Summary of constant discharge test details Pump start time 15th April – 14:00 Pump end time 17th April – 14:00 Total pump time 48 hours Target discharge rate 30 l/s Average discharge rate 30.8 l/s

This test involved 48 hours of pumping from the well at a constant flow rate. The target flow rate for this test was 30 l/s, although an average flow rate of 30.8 l/s was calculated from the recorded test data. Water levels in two nearby bores (M36/2693, M36/7712) were monitored during the testing period for assessment of well interference effects. Water pumped from the well was discharged \\NZCHC1FP001\Projects\605X\60586487\400_TECH\Well Interference Assessment\Report\Burnham Well Interference Assessment Report Rev 2.docx Revision – 16-May-2019 Prepared for – New Zealand Defence Force – ABN: N/A AECOM Burnham Potable Water Supply Upgrade Project 5 Well Interference and Aquifer Test Report

through above-ground pipework attached to the well with an in-line flowmeter installed a few meters from the well. This pipework fed into a hose which extended over 100 m, beneath a road and then discharged through a perforated pipe onto an NZDF owned field. The depth of the two bores and their distance from the pumping well was deemed sufficient for the discharge to occur to land without it influencing water levels over the testing period

3.2 Constant discharge test analysis Displacement within the pumping well and the two monitoring wells during the test is displayed in Figure 2. Noise is observed in well M36/2693 data, although M36/7712 and the pumping well display smooth data. Following the initial displacement in the pumping well a slight decrease in water levels throughout the remainder of the test observed. The observation wells display a decreasing trend in water level throughout the test, however this trend is considered minor i.e. the maximum displacement over the test period change was less than 10 cm in both observation wells.

Maximum displacements of less than 10 cm were observed in the observation wells over 48 hours of pumping at an average flow rate of 30.8 l/s. This is considered to be minor and suggests there is limited to no connection between the pumping well and changes to groundwater levels in the adjacent wells over the duration of the test. This minor observed trend in groundwater levels could be attributed to background groundwater fluctuations from recharge sources rather than a direct result of the testing undertaken.

4.0 Well Interference Assessment Methodology The effects on the proposed take on other groundwater users have been assessed using the method as described in Schedule 12 of the Canterbury Land and Water Regional Plan (ECAN, 2019). The plan states: “An “acceptable” direct cumulative interference effect is when the direct cumulative interference effect is no greater than 20% of the total available drawdown at times of low water level that is

exceeded 80% of the time during the period of proposed water use, having taken into account individual bore and pump installation details” The cumulative interference for the applicable wells has been analysed using the online interference tool (http://tools.ecan.govt.nz/wqn10/). Calculated aquifer parameters assuming a Hantush – Jacob (1955) Solution (Table 1) were used during the assessment. The default WQN10 parameters were utilised in the assessment and no wells were excluded. This is considered a conservative approach. URS (2009) reported a number of bores within the vicinity of the site where the presence of significant layers of low permeability confining material between 50 m bgl and 80 bgl, with the shallow aquifer apparent between 35 m bgl and 50 m bgl. The provided bore record for the new bore also shows this low permeability layer as present between 60 and 86 m bgl. Therefore it has been conservatively assumed that the vertical extent of the deep aquifer system was 70 m bgl for the well interference assessment. The results of the WQN10 are provided in Appendix B. In total 27 wells were identified to be located within 2,000 m of the bore field that may be adversely affected by the new potable supply well. None of these wells exceed that allowable 20% of available drawdown.

5.0 Conclusion Aquifer transmissivities of 254 and 354 m2/day were calculated through application of two analytical methods to the step test displacement data. The lower value, which was derived using the Hantush – Jacob (1955) solution, is considered more representative of the actual aquifer transmissivity because it accounts for vertical leakage. The aquifer tested is considered likely to be leaky based on the conceptual hydrogeological model. A minor reduction of water levels of less than 10 cm was identified in the observation well data during the well interference assessment. It is not clear whether this trend is associated with the test itself or can be attributed to background groundwater fluctuations, however the drawdown observed is considered to be minor over the period of assessment. The well interference assessment undertaken using the online WQN10 tool suggested no wells within 2,000 m of the bore field will exceed the allowable 20% of available drawdown as per Schedule 12 of the Land and Water Regional Plan. It is therefore considered that the impact of the proposed water take on the surrounding bore users is likely to be less than minor.
