On Page after Objective WQL5, Policy WQL21 has been inserted as follows: Policy WQL21: Enable the repair of earthquake damaged land on sites used for residential activities (1) Until 31 December 2018, and where the site was used for residential activities as at 4 September 2010, enable within the area shown in Schedule WQL14, the repair of earthquake damaged land within specified thresholds as permitted activities. Beyond these thresholds, provide for land repair activities by way of a resource consent, where the adverse effects on the environment are mitigated. (2) Ensure a focused and expedited decision making process for landowners by requiring resource consent applications to be processed and considered without public or limited notification. In addition, ensure the social, economic, cultural and environmental well-being of communities is met by requiring adverse effects from the repair of earthquake damaged land to be mitigated through conditions of consent. 15. On pages , Table WQL8 specifies the areas to which the rules in Chapter 4 of the NRRP apply. Where an activity described in Rule WQL36A is carried out, Rule WQL36A will apply instead of the existing rules in the NRRP that relate to that activity. To clarify where the rules apply, the following amendments to Table WQL8 have been made. Where the rule applies Rule No. Activity type Description Activity Status Page No. Everywhere in the Canterbury region excluding where the discharge is to a river, lake or artificial watercourse, or onto or into land, and is controlled by the Opihi River Regional Plan or the Waimakariri River Regional Plan or is an activity that is classified by Rule WQL36A.

Any material deposited into land consists only of uncontaminated fill (soil, rocks, gravels, sand, silt, clay), concrete, cement, grout, concrete steel or timber foundation piles, or inert building materials. 5. From the date this rule becomes operative, the use of land for the placement of treated timber foundation piles into confined groundwater within the Coastal Confined Aquifer System, and any discharge from those foundation piles, does not occur within a community drinking water supply protection zone, as set out in Schedule WQL2 of this plan. 6. Any excavation over the coastal confined aquifer system maintains at least one metre of undisturbed material between the deepest part of the excavation and Aquifer No materials (other than those listed in condition 4) vehicles or machinery (excluding clean uncontaminated equipment used for dewatering, and infrastructure installed for the purposes of land repair) are deposited into or used within groundwater. 8. Compaction, or earthworks involve below ground soil disturbance (excluding filling), do not occur on any part of a site which is identified as a landfill. 9. There is no discharge of any cement, concrete, grout, or water containing cement, grout or concrete, into any surface waterbody, or beyond the property boundary. 10. Where grout is deposited into land, or into groundwater, the following conditions also apply: a) The volume of grout shall not exceed 50 cubic metres per site. b) The point of deposition into land is not within: (i) (ii) 20 metres of any surface water body, or 20 metres of the Coastal Marine Area, where the material is deposited into groundwater; or 10 metres of any surface water body, or 10 metres of the Coastal Marine Area, where a separation of one metre is maintained between groundwater and any deposited material. c) Where grout is deposited into land via in-situ mixing:

8 For the purposes of this rule: Grout means a material which consists of water and at least 20% cement, and which may also contain aggregate, inert additives, or bentonite. Earthquake Damaged Land means land damaged as a result of the Canterbury Earthquake Sequence that commenced on 4 September Landfill means any part of a site where solid or hazardous waste has been deposited (either lawfully or not), and which is identified as a landfill on Environment Canterbury s Listed Land Use Register, or in the records of the relevant territorial authority. Residential Activities means land zoned residential in a district plan, or land used predominantly for residential occupation, as at 4 September Notification An application for consent under this rule shall be processed and considered without public or limited notification. Where Rule Applies: This rule applies only within the area shown in Schedule WQL14 Information to be provided An application for a resource consent under this rule must meet the information requirements set out in Section and Section 4.7. (i) the grout shall be mixed evenly throughout the augured soil column; and (ii) the percentage of grout within the area of the augured soil column shall not exceed 20%. d) Where the grout is deposited into land using methods other than in-situ mixing, the percentage of cement in the dry grout mixture shall not exceed 30%. 11. To prevent erosion, bare ground is stabilised within 10 days of any vegetation clearance or earthworks. 12. For earthworks carried out within the riparian margin, in addition to conditions (3) and (11), the following conditions apply: a) Vegetation used and maintained by Environment Canterbury for flood or erosion control purposes is not removed. b) Replanting is not of a species listed in the Biosecurity NZ Register of Unwanted Organisms or Canterbury Pest Management Strategy. c) The activities do not reduce the available floodway d) The activities do not result in the destabilisation of the bank of any river, lake or natural wetland, or destabilise any existing lawfully established structures, or interfere with access to waterways for maintenance or inspection purposes. Geotechnical Investigations 13. The bore is used only for the purposes of geotechnical investigations and is decommissioned by filling with clean material and compacted or sealed at the surface to prevent contaminants entering the bore. 14. Information on location (including bore logs and intended uses), and other relevant information is submitted to the CRC within 20 working days of drilling the bore. Dewatering, Sediment-laden Water, and Land Drainage 15. Dewatering and land drainage discharges are not from, or discharged onto or into any site listed on Environment Canterbury's Listed Land Use Register. 16. The taking of groundwater for dewatering purposes does not lower the groundwater level more than 8 metres below the ground level of the site. 17. The taking and discharge of land drainage water and site dewatering water onto or into land or into surface water does not result in subsidence of the land surface, or bed or bank erosion. 18. The discharge of dewatering water onto or into land or into surface water does not result in any flooding of any neighbouring property, or result in ponding on the land surface for more than 48 hours. 19. The concentration of suspended solids in any dewatering water, or sediment-laden water discharged to a surface water body does not exceed 100 grams per cubic metre. Restriction of Discretion Cross reference: This rule contributes to the implementation of Policy WQL21 Where the activity is classified as a restricted discretionary activity, Environment Canterbury has reserved its discretion to the following matters: cultural effects 1. The effect of not meeting the condition or conditions of Rule WQL36A 2. Mitigation Measures proposed to be implemented or mitigation measures available to minimise any actual or potential environmental effect.

9 23. On Page 4-183, within Rule WQL37, in the left hand column of the rule under the heading Where Rule Applies, the rule has beenamended as follows: This rule applies everywhere in the Canterbury region, excluding: the Coastal marine area the Coastal marine area; or Where the activity is classified by Rule WQL36A. 24. On Page within the section entitled Explanation and principle reasons for methods which commences at Page a new paragraph after the explanation note for Rule WQL36 as been inserted as follows: Rule WQL36A The repair of earthquake damaged land on individual sites used for residential activities, and the associated taking and discharge of groundwater for dewatering and land drainage purposes Rule WQL36A recognises the exceptional circumstances following the Canterbury Earthquake event sequence that commenced on 4 September The rule provides for the repair of earthquake damaged land zoned on individual sites zoned for residential activities, or where the land was used for residential activities, as a permitted activity subject to compliance with the conditions of the rule. In recognition of the need for a simplified planning process for landowners, the rule adopts the concept of rule bundling where several different RMA permissions (s9, s14, s15) have been combined into a single rule. The rule applies only to the repair of land on individual sites used for residential activities and which is located within the area shown in Schedule WQL14. The boundary of Schedule 14 takes into account the boundary of the Greater Christchurch Area, and loosely aligns with the boundaries of the Christchurch-West Melton, Waimakariri and Selwyn-Te Waihora sub-regional areas (as defined in the notified version of the proposed Land and Water Regional Plan), It is considered appropriate to limit the rule s application to land located within the sub-regional areas given the geographic extent of the land damage The rule does not apply to the repair of earthquake damaged land within the residential red zone (as classified by the Canterbury Earthquake Recovery Authority), or to the repair of earthquake damaged land located within the High Soil Erosion Risk Areas identified in Schedule WQL15. Land repairs within the High Soil Erosion Risk area have been excluded from the rule as works within this area pose a greater environmental risk due to the erosive nature of the loess soils, and the need for specific erosion and sediment control measures. Land repair carried out within these excludes areas are subject to the existing rules in the regional plans, and will require a resource consent if the conditions of the rule are not complied with. The rule requires erosion and sediment control measures to be implemented and maintained during the duration of the works, and land is to be stabilised within 10 days of completion of the works in order to minimise the discharge of sediment laden water, dust generation and effects on aquatic ecosystems (conditions 3 and 11). To avoid adverse effects on groundwater quality, the rule limits the deposition of material to only uncontaminated fill, concrete, cement, grout or concrete, steel or timber building foundations; and uncontaminated equipment necessary to carry out the works (conditions 4 and 7). In addition any geotechnical bores must be sealed and compacted to ensure these bores do not act as a conduit for contaminants to enter groundwater (condition 13). Where foundation piles are placed into land, the activity is generally permitted, except in circumstances where the treated timber piles intercept confined groundwater in the Coastal

10 Confined Aquifer System and their location occurs within a Community Drinking Water Supply Area. In these circumstances a resource consent is required in order to allow the council to consider the effects of the discharge from treated timber piles on groundwater quality and users. The use of alternative foundation options which do not pose a risk to groundwater quality (e.g. concrete or steel piles) is a permitted activity. Where earthworks are to be carried out on a landfill site, additional conditions must be complied with in order to mitigate potential adverse effects on groundwater quality (condition 8). Earthworks which are unlikely to result in disturbance of landfill material are permitted (e.g. filling land or cracks). However, methods which may disturb landfill material and result in the migration of landfill leachate into groundwater will require a resource consent, in order to allow the council to fully assess the effects of the activity. Where cement based materials are used, there is the potential for adverse effects on surface water quality (resulting from changes in ph) if the material is not managed appropriately. The rule prohibits the surface run-off of concrete, cement or grout into surface water, or water containing this material is prohibited by the rule (condition 9). Grout presents a higher risk to surface water quality given the greater mobility of the material and the higher proportion of cement in the material. Consequently, in order to avoid adverse effects on surface water quality and ecosystems, additional restrictions apply where grout is deposited into land or groundwater. These restrictions include a limit on the amount of grout deposited into land, and a requirement to maintain separation to surface waterbodies (condition 10). Grouts used for insitu mixing typically contains a very high proportion of cement content (up to 70%), and consequently there is the potential for significant changes in alkalinity of receiving groundwater and nearby surface water, unless the grout is uniformly mixed with the insitu soil, and the cement in the final column limited to 20% (condition 10c) Alternative land repair methodologies (e.g. low mobility grouting) often do not rely on mixing of in-situ soil with the grout. Consequently there is a need to limit the percentage of cement in the dry grout mix, in order to avoid significant changes in alkalinity in the receiving groundwater within riparian areas works are to be managed in a manner which avoids adverse effects on existing structures, and ensures the flood capacity of the waterway is maintained (condition 8). Where dewatering occurs, adherence to additional conditions is required, to ensure adverse effects on ecosystems, surface water quality and neighbouring property owners are avoided. Dewatering from sites, or onto sites listed on Environment Canterbury s Listed Land Use Register is not permitted under the rule, as former activities carried out at these sites may have resulted in land contamination (condition 15) A limit of 100 grams per cubic metre of total suspended solids in any dewatering water or sediment laden water discharged to surface water has been imposed to minimise adverse effects caused to aquatic organisms through sedimentation (condition 19). 25. Amendments have been made to insert Schedule WQL14 and Schedule WQL15 into the Water Quality Schedules section of Chapter 4 of the NRRP The amendments are as follows: 26.

The NRRP applies to the whole Canterbury region addressing issues on a regional or sub-regional basis. It does not apply to those issues specifically addressed by the Waimakariri River Regional Plan, except that the objectives, policies and regional rules relating to the repair of earthquake damaged land on individual sites used for residential activities apply within the area addressed by the WRRP, where the activity is carried out within the boundaries of Greater Christchurch. The NRRP will be prepared in stages and eventually it will replace the Transitional Regional Plan and may also replace this and some other regional plans.

17 Appendix 1 Policy wording inserted into the Christchurch-West Melton, Waimakariri, Selwyn-Waihora sub-regional sections of proposed Land and Water Regional Plan (1) Until 31 December 2018, and where the site was used for residential activities as at 4 September 2010, enable within the area shown in Map 1, the repair of earthquake damaged land within specified thresholds as permitted activities. Beyond these thresholds, provide for land repair activities by way of a resource consent, where the adverse effects on the environment are mitigated. (2) Ensure a focused and expedited decision making process for landowners by requiring resource consent applications to be processed and considered without public or limited notification. In addition, ensure the social, economic, cultural and environmental well-being of communities is met by requiring adverse effects from the repair of earthquake damaged land to be mitigated through conditions of consent.

18 Appendix 2 Permitted Activity Rule wording inserted into Waimakariri, Christchurch-West Melton and Selwyn-Waihora sub-regional sections of proposed Land and Water Regional Plan. Note: For all activities in or near waterways, refer also to the requirements and restrictions under the Canterbury Flood Protection and Drainage Bylaw 2013 Prior to 31 December 2018, the repair of earthquake damaged land located within the area shown on area shown on Map 1, and located outside the High Soil Erosion Risk Areas, and which is carried out on an individual site used for residential activities, but excluding any residential property zoned red by the Canterbury Earthquake Recovery Authority), which involves any one or more of: (a) the use of land for: i. the excavation of material over the unconfined, semi-confined or coastal confined aquifer system; ii. iii. iv. the deposition of material into land or into groundwater, and any associated discharge into groundwater; vegetation clearance or earthworks within the riparian margin (defined for the purposes of this rule as any land within 10 metres of the bed of a river, lake or wetland boundary); the installation, maintenance, and use of a bore for geotechnical investigation or monitoring purposes; v. the installation and construction of building foundations; (b) the discharge of sediment-laden water generated from earthworks into a surface waterbody, or onto or into land where it may enter a surface water body; (c) the taking of groundwater for the purposes of dewatering or land drainage, and the associated discharge of that water into a surface water body, or onto or into land where it may enter a surface water body. is a permitted activity, provided the following conditions, as applicable, are met: General Conditions (1) The extent and duration of any works is limited to only that necessary to repair the land. (2) The works (excluding any discharges associated with the works listed above) do not occur in, the bed of any lake, river or natural wetland. Earthworks, Excavation and Deposition of Material (3) Erosion and sediment control measures are implemented and maintained in accordance with Environment Canterbury s Erosion and Sediment Control Guidelines for Small Sites to minimise erosion and the discharge of sediment laden water to surface water. (4) Any material deposited into land consists only of uncontaminated fill (soil, rocks, gravels, sand, silt, clay), concrete, cement, grout, concrete, steel or timber foundation piles, or inert building materials. (5) From the date this rule becomes operative, the use of land for the placement of treated timber foundation piles into confined groundwater within the Coastal Confined Aquifer System, and any discharge from those foundation piles, does not occur within a group or community drinking water supply protection area, as set out in Schedule 1 of this plan.

19 (6) Any excavation over the coastal confined aquifer system maintains at least one metre of undisturbed material between the deepest part of the excavation and Aquifer 1. (7) No materials (other than those listed in condition (4)), vehicles or machinery (excluding clean uncontaminated equipment used for dewatering, and infrastructure installed for the purposes of land repair) are deposited into, or used within groundwater. (8) Compaction, or earthworks involving below ground soil disturbance (excluding filling), do not occur on any part of a site which is identified as a landfill. (9) There is no discharge of any cement, concrete, grout, or water containing cement, grout, or concrete, into any surface waterbody, or beyond the property boundary. (10) Where grout is deposited into land, or into groundwater, the following conditions also apply: a. The volume of groutshall not exceed 50 cubic metres per site. b. The point of deposition into land is not within: i. 20 metres of any surface water body, or 20 metres of the Coastal Marine Area, where the material is deposited into groundwater; or ii. 10 metres of any surface water body, or 10 metres of the Coastal Marine Area, where a separation of one metre is maintained between groundwater and any deposited material. c Where grout is deposited into land via in-situ mixing: i. The grout shall be mixed evenly throughout the augured soil column; and ii. The percentage of grout within the area of the augured soil column shall not exceed 20%, d. Where grout is deposited into land using methods other than in-situ mixing, the percentage of cement in the dry grout mixture shall not exceed 30% (11) To prevent erosion, bare ground is stabilised within 10 days of any vegetation clearance or earthworks. (12) For earthworks carried out within the riparian area, in addition to conditions (3) through (11), the following conditions apply: i. Vegetation used and maintained by the Canterbury Regional Council for flood or erosion control purposes is not removed. ii. iii. iv. Replanting is not of a species listed in the Biosecurity NZ Register of Unwanted Organisms or Canterbury Pest Management Strategy. The activities do not reduce the available floodway. The activities do not result in the destabilisation of the bank of any river, lake or natural wetland, or destabilise any existing lawfully established structures, or interfere with access to waterways for maintenance or inspection purposes. Geotechnical Investigations (13) The bore is used only for the purposes of geotechnical investigations and is decommissioned by filling with clean material and compacted or sealed at the surface to prevent contaminants entering the bore.

20 (14) Information on location (including bore logs and intended uses), and other relevant information is submitted to the CRC within 20 working days of drilling the bore. Dewatering, Sediment-laden Water, and Land Drainage (15) Dewatering and land drainage discharges are not from, or discharged onto or into any site listed on Environment Canterbury s Listed Land Use Register. (16) The taking of groundwater for dewatering purposes does not lower the groundwater level more than 8 metres below the ground level of the site. (17) The taking and discharge of land drainage water and site dewatering water onto or into land or into surface water does not result in subsidence of the land surface, or river bed or river bank erosion. (18) The discharge of dewatering water onto or into land, or into surface water, does not result in any flooding of any neighbouring property, or result in ponding on the land surface for more than 48 hours. (19) The concentration of suspended solids in any dewatering water or sediment-laden water discharged to any surface water body does not exceed 100 grams per cubic metre. For the purposes of this rule the following definitions apply: Earthquake Damaged Land means land damaged as a result of the Canterbury Earthquake Sequence that commenced on 4 September 2010.: Residential Activities means land zoned residential in a district plan; or land used predominantly for residential occupation as at 4 September Grout means a material which consists of water and at least 20% cement, and which may also contain aggregate, inert additives or bentonite. Landfill means any part of a site where solid or hazardous waste has been deposited (either lawfully or not), and which is identified as a landfill on Environment Canterbury s Listed Land Use Register, or in the records of the relevant territorial authority.
