Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Executive Summary

Davis Ogilvie & Partners Ltd. has been engaged by Hilton Haulage Ltd to undertake a Detailed Site Investigation at 330 and 340 Port Hills Road, Hillsborough, Christchurch, where it has been proposed to amalgamate the existing lots and construct a custom built transport yard, beginning with construction of a new warehouse adjacent to Port Hills Road. Consideration has been given to data acquired from local resources including the New Zealand Geotechnical Database, Environment Canterbury, the Christchurch City Council Property File, and former reporting on the site. Data has also been collected during onsite investigations by Davis Ogilvie & Partners Ltd.

Analytes above the selected Nil criteria for human health

Concentrations of heavy metals exceed background levels in fill soils across the site. However, no samples exceed the recommended commercial trigger values, therefore a complete exposure pathway does not exist. In addition to elevated heavy metal concentrations, the stockpile and the bitumen layer at 0.5 m deep show elevated concentrations of polycyclic aromatic hydrocarbons.

Any soil removed from the site during development will need to be disposed of at a facility authorised to accept it (such as Burwood Landfill).

Under the NESCS (2011), the proposed subdivision (amalgamation) and soil disturbance will be a Controlled Activity, in accordance with Regulation 9 (1) and 9 (3) of the NESCS.

A number of PAHs were detected at concentrations above the ANZECC ISQG-High guideline values in the bitumen layer at 0.5 m below EGL, as well as in the stockpile.

In accordance with Environment Canterbury Land and Water Regional Plan Rule 5.185 the person or organisation initiating the site investigation must provide a copy of the report of the site investigation to the Canterbury Regional Council within two months of the completion of the investigation.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016

1.0 Introduction

Davis Ogilvie & Partners Ltd (Davis Ogilvie) has been engaged by Hilton Haulage Ltd (the Client) to undertake a detailed site investigation (DSI) at 330 and 340 Port Hills Road, Hillsborough, Christchurch (“the site”). The DSI was undertaken in accordance with the Davis Ogilvie Letter of Engagement dated 15 August, 2016.

1.1 Background It is understood that Hilton Haulage Ltd has plans to develop the entire site to create a custom built transport yard. Davis Ogilvie also understand that an adjustment of lot boundaries is proposed.

The Resource Management (National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health) Regulations 2011 (NESCS, 20111) applies to certain activities all sites where an activity or industry on the Ministry for Environment’s (MfE) Hazardous Activities and Industries List (HAIL)2 list is, has, or is more likely than not to have occurred. Soil disturbance/removal and subdivision (lot adjustment) are activities covered by the NESCS.

The site is currently listed on the Environment Canterbury (ECan) Listed Land Use Register (LLUR, Appendix A)3 due to activities associated with a historic orchard. An area within the northern part of the site comprises part of an area that is also listed on the LLUR as having held fuel storage tanks and/or asbestos products related to a foundry. The LLUR reports state that the site is currently categorised as “not investigated”.

As the property has accommodated HAIL activities in the past, the requirements of the NESCS are likely to apply, and investigation of the site is required to facilitate development of the site.

1.2 Objectives The objectives of this DSI were to:  Assess whether potential contamination relating to the HAIL activities on the site are present at concentrations that may present a risk to human health.  Assess the need for NESCS resource consent associated with soil disturbance and removal work required for the proposed development.  To characterise material that potentially requires off-site disposal.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 1 These objectives were met by investigating the presence and extent of contamination (if any) within the soil. The area being assessed in this report was limited to where the soil is to be disturbed during the proposed redevelopment works at the site.

1.3 Scope of Work The following scope of works have been undertaken to meet the objectives of this investigation:  Desk study comprising review of the property’s Land Information Memorandum (LIM) and Property File records from Christchurch City Council (CCC), review of the LLUR, and review of historic aerial photographs from ECan.  Site walkover and inspection of the property.  Collection of soil samples for laboratory analysis.  Preparation of this report, including presentation and interpretation of results in accordance with the requirements of the NESCS.

2.1 Site Description and Surrounding Environment The subject site (Figure 1) is a 5.3 ha area comprised of four lots that is located in the Christchurch suburb of Hillsborough, approximately 5.0 km southeast of the Christchurch Central Business District. The site is currently accessed primarily from a driveway off the western end of Desi Place, with a secondary access off the southern side of Curries Road.

The site is located on flat ground a short distance north-east from the base of the Port Hills. The land on the adjacent side of the road, as close as 25 m from the south-west boundary of the site, rises steeply up slope towards Mt Vernon. The land to the northwest of the site is predominantly developed with residential dwellings along Curries Road. The surrounding area from the north through to the southeast is developed commercial and industrial land.

At the time of the investigation various land uses and activities were present on the site. These included building materials storage (some stockpiled scrap building materials), concrete crushing/stockpiling, landscaping supplies bulk storage, warehouse storage facilities, a trucking/container storage operation, various small workshop/fabrication operations and office/administration facilities. A large (approximately 5000 m3) stockpile of gravel, concrete and crushed concrete is located within the western part of the main yard. A significant portion of the site is hard stand.

A number of metal drums were observed on the site during the site inspection carried out in September, 2016. Labels on the drums indicated a number of different oils (Morris Lubricants, RX Super Plus, Hyspin AWS 46, and engine oil), Purigo 5S Concrete Dustproofer (activated sodium silicate), and the solvent xylene. While these drums ranged from good condition to severely corroded, they were generally on areas of hard stand, and no evidence of spills, leaks or soil impact was observed in the vicinity of the drums.

Davis Ogilvie have been advised that the two red-roofed buildings within Lot 2 (refer Figure 1) were partially constructed with asbestos containing materials (ACM). It is understood that these two buildings are due to be demolished in the near future. Prior to the demolition works, the ACM is to be removed by an appropriately qualified and certified contractor.

A drainage channel extends along the eastern boundary of the site, and flows northwards to the Heathcote River which is located 270 m north east of the site at its closest point. The reaches of Heathcote River near the site are tidal.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 4 2.2 Geology and Hydrogeology The published geological map for the area (Figure 2)4 identifies the site as covering an area of three differing geological units. The majority of the site is indicated to be underlain by alluvial sand and silt overbank deposits (grey river alluvium, comprising gravel, sand and silt, in active floodplains (Yaldhurst Member of the Springston Formation)). A small strip of land at the Port Hills Road end of the site (along the south-west boundary) is underlain by valley fill and slope wash of loess-volcanic colluvium. The northeast edge of the site, closest to the railway lines, is indicated to be underlain by sand, silt and peat of drained lagoons and estuaries (Christchurch Formation).

Figure 2: Image showing the published geology underlying the site (red polygon) and surrounding land.

Soils encountered during the DSI comprised up to 1.0 m thickness of fill materials overlying natural sand, silts and clay. The fill materials encountered consisted predominantly of gravel, with varying amounts of demolition waste debris, such as concrete, plastic, wire, pipe, wood, asphalt and brick.

A review of the New Zealand Geotechnical Database depth to median water table5 indicates groundwater at the site is likely to be present between 1.0 – 2.0 m below existing ground level (EGL). Smaller areas are to the west of the site are indicated to be between 2.0 – 3.0 m and an isolated area at the southern end of the site is indicated to be between 0.0 – 1.0 m below EGL. Groundwater was encountered at not encountered during the DSI. During a geotechnical

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 5 investigation carried out at the site6 shallow groundwater was encountered in natural soils in the approximate range 0.9 m to 1.8 m below EGL. Perched water was also encountered in a number of test pits at depths in the range 0.2 to 0.5 m below EGL. Surface water present in the drain along the eastern side of the site is considered likely to be directly connected to shallow groundwater under the site. Groundwater levels are expected to vary spatially and seasonally.

Online ECan maps of Canterbury aquifers7 show that the site is situated over a coastal confined gravel aquifer system. The Canterbury Land and Water Regional Plan (LWRP) indicates there are two nearby community water extraction wells and surrounding protection zones. Figure 3 shows the protection zones are close to but do not extend over the subject site.

2.3 Site History The history of the site has been ascertained through a study of historic aerial photography, the CCC property file and Land Information Memorandum (LIM) records, and discussion with Mr Terry Birchfield who has lived on and developed the site over the last decade. Historic survey plans and Certificates of Title were reviewed for this study, but did not provide any additional information of value. Historic aerial photography of the site (Appendix B) is available from ECan8 and provides an image the site every decade, from 1941 to 1994. Google Earth provides more recent aerial imagery, from 2004 to 2016. The history is summarised below, and the locations of various items are shown in Figure 4.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 6 Pre-1940s – 1950s: Farm land and possible filling The land between Port Hills Road and the Heathcote River was owned by Mr Edward Garland and descendants from 1854 to the early 20th century (Ogilvie, 20099). The Garland family grazed cows on the flat land, and grew some oat or clover crops.

The CCC LIM record for 340 Port Hills Road (issued 3 June 2016, available in the CCC Property File) notes that the property is located in an area which is known to have been a landfill. There is no evidence of land filling activity in aerial photography of the site from the 1940s onward, therefore it is assumed that this activity, if it occurred, would have taken place prior to this time. The CCC Landfill Sites map shows a circular rubbish landfill on the site, but gives no further information. Mr Birchfield, the former owner and developer of the site, has indicated that no landfill is present in this area to his knowledge.

Aerial images of the site from 1941 and 1946 show the site as undeveloped farm land, with several paddocks separated by hedgerows. A single small building is present on the site adjacent to Port Hills Road. Some rows of crops are visible in the north-eastern area of the site. At some time between 1941 and 1946 a building was constructed in the north-eastern corner of the site, which was part of a neighbouring property at that time.

1950s – 1960s: Orchard and earthworks An aerial image of the site from 1955 shows a triangle-shaped orchard through the centre of the site, and the small building on Port Hills Road having been removed. The orchard remained on site through the 1960s, as shown in 1965 aerial imagery.

A subdivision scheme plan dated 1960 shows Pt Lot 16 labelled “Industrial Metals Ltd”, and some earthworks and ground disturbance is visible within Pt Lot 16 in the 1965 aerial image. It is believed, however, that most of the scrap metal business was conducted on the neighbouring site to the west as the 1965 aerial photograph shows scrap stockpiles on the neighbouring site. Furthermore, a Christchurch City Libraries article10 on the Hillsborough Tavern which burnt down on the neighbouring property in 2009 indicated that that site was a former scrap metal yard (Pacific Scrap Ltd).

1970s – 1990s: Wedding and Convention Centre In the 1970s much of the triangular orchard was removed to provide space for buildings for the Old Orchard Wedding & Convention Centre, which operated on the site until at least 2003. A note on the CCC property file dated 2003 indicates that the Convention Centre buildings were former residential buildings which were converted for use. A large carpark and landscaped area was constructed around the convention centre buildings. The Hillsborough Tavern Drain is

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 7 visible from the 1970s until recent times, extending along the western side of Pt Lot 16 to Curries Road. In the 1994 aerial image significant soil disturbance is visible in the northern half of the site, likely as a precursor to development.

2000s – 2010s: Warehouse construction and development A 2002 aerial image of the northern half of the site provided in the CCC property file shows significant development, with several soil stockpiles and items stored on site, and one warehouse constructed. It is understood that all buildings and warehouses currently present on the site have concrete floors. A note in the CCC property file indicates that many of the warehouses were transported to the site from previous locations such as Cashin Quay, Rattrays, or the Lyttelton Port.

Several containers were stored in the area immediately west of the Conference Centre buildings around 2006. This area was used for timber storage in 2014. By 2009, the access way through number 24 Curries Road is complete, with new landscaping down either side of the path. A photograph in the CCC property file shows the access way under construction, with a gravel fill surface layer across the area.

Mr Birchfield has described that when he was preparing the site he stripped the original topsoil which was sold to Rangiora Landscapes and Gardenmakers and taken off site. He subsequently backfilled large areas of the site with volcanic rock from the Lyttelton Port coal yard area.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 9 3.0 Site Characterisation

3.1 Land Use The site history indicates that the site has had mixed historical use including agricultural and commercial / industrial land use. Current land use is commercial / industrial in nature. The proposed development will not result in a change of land use.

3.2 Identified HAIL Activities On the basis of the desk study and site inspection, potential HAIL activities identified for the site include the following:  A10 – Persistent pesticide bulk storage or use (historical orchard).  A17 – Drums for fuel, chemicals or liquid waste (drums observed onsite).  A18 – Bulk storage of treated timber outside (2014 storage).  E1 – Asbestos products including disposal and buildings containing asbestos products known to be in a deteriorated conditions (associated with former foundry, onsite buildings)  G3 – Landfill site (possible historic landfill)  G5 – Waste disposal to land (associated with filling of the site and current large concrete stockpile).

The primary potential contaminants of concern associated with these HAIL activities include heavy metals, organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs) and asbestos.

3.3 Potentially Relevant Receptors The following potential receptors were identified as being relevant to the site:  Existing users of the site.  Earthworks, maintenance and excavation contractors who may come into contact with potentially contaminated soil during planned site development works.  Future users / occupiers of the site.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 10 4.0 Soil Sampling

4.1 Methodology Soil samples were collected from the surface and subsurface soils through a series of test pits and hand augers across the site. A significant portion of the site was unable to be sampled due to areas of hard stand, existing buildings, and the presence of a large gravel stockpile on the site – see shaded areas in Figure 4.

A total of 28 test pits or hand augers were excavated across accessible areas of the site. Sampling locations are indicated on Figure 5 (Appendix C). Encountered soils were logged and up to three samples collected from each sampling location. Test pits logs are included as Appendix D.

The gravel and concrete stockpile in the western part of the main yard was also sampled, with 22 samples collected across the stockpile.

During the test pitting operation and site walkover three pieces of potentially asbestos containing material (ACM) were observed on the site. These three pieces of possible ACM were collected for laboratory analysis. A total of 13 soil samples were also collected during the sampling program for analysis for asbestos fines. Seven samples were collected from the gravel and concrete stockpile and the remaining six from the wider site area.

4.2 Soil Sampling Procedure The following procedures were adopted during investigation works:  All field work was carried out in compliance with project specific hazard identification procedures.  All works were conducted by trained staff with precautions taken including implementation of procedures for the appropriate handling of potentially contaminated material.  Prior to sampling and between sample locations, sampling equipment was cleaned by washing with clean tap water, followed by decontamination solution, and rinsing with clean tap water.  Soils encountered during sampling were examined for the presence of visual and olfactory evidence of contamination.  Soil samples were collected using either a stainless trowel or hand auger and a clean new pair of nitrile gloves per sample and then placed directly into a laboratory supplied sample container.  Following collection, all soil samples were placed directly into storage and transported under standard Davis Ogilvie chain of custody procedures, to Eurofins Laboratory for analysis.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 11  At each sample location, any remaining soil that was not collected into sample jars was placed back into the sampling hole.  Samples of potential ACM were collected into zip lock bags and delivered to CRL Energy LTD (CRL) for analysis.

4.3 Laboratory Analysis A total of 44 samples collected from test pits and hand augers advanced over the wider site area were selected for analysis. All selected samples were analysed for heavy metals. 19 samples were analysed for PAHs and 9 samples analysed for OCPs. One sample (TP5-HH12) was analysed for semivolatile organic compounds (SVOCs) and one sample (TP21-HH50) analysed for Total Petroleum Hydrocarbons (TPH).

22 samples were collected from the gravel and concrete stockpile for analysis. All samples were analysed for heavy metals, 10 samples analysed for PAHs and 6 samples for OCPs.

Three potential ACM samples were analysed for asbestos presence/absence. Thirteen collected soil samples were analysed for asbestos fines (presence / absence).

4.4 Quality Assurance and Quality Control Two duplicate soil samples (TP31-HH70 being the duplicate of TP31-HH69, and TP32-HH68 being the duplicate of TP32-HH67) were collected to measure variation in sampling methodology and laboratory analysis. Each primary / duplicate pair was analysed for heavy metals. The relative percentage difference (RPD) was calculated for each duplicate pair and ranged from 0% (analyte not detected or the same concentration) to 40%, within an acceptable RPD range of 50%.

Eurofins are an internationally recognised laboratory that is endorsed by International Accreditation New Zealand (IANZ) which represents New Zealand in the International Laboratory Accreditation Cooperation (ILAC). Through the ILAC Mutual Recognition Arrangement (ILAC-MRA) this accreditation is internationally recognised. The tests were performed in accordance with the terms of accreditation.

Asbestos analysis was conducted by CRL Energy Ltd who are also a recognised laboratory that is endorsed by International Accreditation New Zealand (IANZ) which represents New Zealand in the International Laboratory Accreditation Cooperation (ILAC). The tests were performed in accordance with the terms of accreditation.

5.1 Applicable Soil Contaminant Standards

5.1.1 Background concentrations Under Regulation 5 (9) of the NESCS, where a DSI exists that demonstrates that contaminants in or on the piece of land are at, or below, background concentrations, then the NESCS Regulations do not apply. Soils likely to be disturbed at the site during proposed development works predominantly comprise fill. The origin of the fill is unknown; therefore, the highest background values from the variety of urban Christchurch soils have been adopted for the fill soils on site.

Accordingly, background concentrations for this area have been adopted from:  Environment Canterbury, 20017. Background Concentrations of Selected Trace Elements in Canterbury Soils. Addendum 1: Additional Samples and Timaru Specific Background Levels. Report R07/1/2.  Environment Canterbury, 2007. Background Concentrations of Polycyclic Aromatic Hydrocarbons in Christchurch Urban Soils. Report No. R07/19. Table 9.  Ministry for the Environment, 1998. Organochlorines in New Zealand: Ambient concentrations of selected organochlorines in soils. MfE, Wellington. Appendix F, Table F5. By summing the concentrations of each of the DDT compounds, ECan have adopted an ambient concentration for DDT and associated metabolites (∑DDT) of 0.431 mg/kg11 in the Christchurch area.  For those pesticides without defined background concentrations, the laboratory limit of reporting (LOR) has been adopted as the background value.

Adopted background criteria are presented in Tables 1 and 2 (Appendix E).

5.1.2 Priority Contaminants: Soil Contaminant Standards The User’s Guide to the NESCS12 details Soil Contaminant Standards (SCSs) for seven inorganic substances and five organic compounds (or groups of compounds). SCSs are available for these substances and compounds when present in land used for five land use scenarios. The contaminants analysed at this site for which SCSs are available are arsenic, cadmium, chromium, copper, lead, mercury, DDT, dieldrin and Benzo(a)pyrene Toxic Equivalency (BaP TEQ).

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 13 For this site, a commercial land-use exposure scenario has been adopted for screening purposes which includes the following source/pathway/receptor assumptions:  Potential receptors include site workers during the construction works and onsite following completion of the development.  There are no specific SCSs associated with construction/excavation workers. Accordingly, the SCSs for commercial land use have been adopted to enable conservative evaluation of potential risk to construction workers for the development.  It has been assumed that the soil pH is 5, and that all lead is present in inorganic form.

SCSs adopted for the site are presented in Tables 1 and 2.

5.1.3 Other Applicable Human Health Standards For contaminants of concern that are not listed as priority contaminants, the NESCS references the Contaminated Land Management Guidelines No. 2: Hierarchy and Application in New Zealand of Environmental Guideline Values13 to provide guidance.

For the two heavy metals detected at the site for which SCSs are not available (nickel and zinc) the Australian National Environment Protection (Assessment of Site Contamination) Measure (NEPM)14 concentrations have been adopted for screening assessment purposes for a commercial/industrial scenario.

For several PAHs, the MfE Guidelines for Assessing and Managing Contaminated Gasworks sites in New Zealand – Module 4 Soil Acceptance Criteria, have been selected (MfE 1997). Health risk based acceptance criteria for a commercial/industrial scenario have been adopted.

For naphthalene and pyrene, Tier 1 screening criteria from the MfE Guidelines for Assessing and Managing Petroleum Hydrocarbon Contaminated Sites in New Zealand15 have been selected. Tier 1 soil acceptance criteria for commercial/industrial use, All Pathways, sandy silt, <1.0 m depth have been used.

5.1.4 Soil Disposal Criteria In addition to assessing the human health and discharge risks associated with soil disturbance and end use of the site, an assessment of off-site disposal options for any

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 14 excess soil generated during site works has been conducted. Dependent on contamination concentrations, the off-site soil disposal options range in cost, from low to high, from disposal to cleanfill sites through managed fill sites to licensed hazardous waste landfills. Disposal to a cleanfill site represents the most cost effective off-site disposal option. MfE16 defines cleanfill material as:

Material that when buried will have no adverse effect on people or the environment. Cleanfill material includes virgin natural materials such as clay, soil and rock, and other inert materials such as concrete or brick that are free of:  Combustible, putrescible, degradable or leachable components.  Hazardous substances.  Products or materials derived from hazardous waste treatment, hazardous waste stabilisation or hazardous waste disposal practices.  Materials that may present a risk to human or animal health such as medical and veterinary waste, asbestos or radioactive substances.  Liquid waste.

The requirement for the material to be free of hazardous substances effectively requires that the concentrations of compounds be below background concentrations for the local or regional environment. For compounds without established background levels, the concentrations should be below the level of analytical detection. For disposal to a cleanfill, soil sample results can therefore be assessed against the background criteria adopted in Section 5.1.

5.1.5 Stormwater Consent Evaluation Rule 5.96 of the Canterbury Land and Water Regional Plan (LWRP) relates to the discharge of stormwater onto or into land (ECan, 2015). ECan have clarified consent requirements under this rule as follows:  If soil concentrations are less then ANZECC ISQG-High sediment quality criteria or the volume of soil disturbance is less than 25 m3, then stormwater discharge associated with construction phase earthworks fall under the CCC Interim Global consent, and do not require application for separate stormwater discharge consent.  Sites with soil concentrations in excess of ISQG-High criteria will be assessed by ECan on site specific basis, with sites classified by ECan as medium or high risk requiring consent application for the construction works, and possibly also requiring an on-going ‘operational’ consent application following completion of the construction works.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 15 As such, to evaluate the potential for soil disturbance to trigger the requirement for stormwater discharge consent, soil analytical results can be compared to ISQG-High sediment quality criteria from the Australian and New Zealand Environment and Conservation Council (ANZECC)17. Relevant guideline criteria for this evaluation are included in Tables 1 and 2 (Appendix E).

5.2 Field Observations Fill materials encountered during test pit excavation included a layer of black asphalt or bitumen debris up to 100 mm in thickness, at approximately 0.5 m below EGL (Test Pits 1, 11, 18, 19, 21, 22, 23, 25, and 32). No other visual or olfactory evidence of significant ground contamination was observed during the DSI. No evidence of the supposed historic landfill was encountered during the investigation program.

5.3 Soil Analytical Results Soil analytical results are summarised in Tables 1 and 2 (Appendix E), and the laboratory analytical results are included in Appendix F. A summary of the chemical results is as follows:  No analysed contaminants of concern were detected at concentrations in excess of the adopted commercial/industrial SCS.  Concentrations of a variety of heavy metals and PAHs were detected at concentrations in excess of adopted background in soil samples collected from across the site area and from the gravel and concrete stockpile.  OCPs were not detected above the laboratory level of reporting (LOR) in any of the soil samples analysed for OCPs. TPH was not detected above the laboratory LOR in the sample analysed.  PAHs were reported at concentrations above the ANZECC ISQG-High sediment quality guideline values in eight samples. The highest PAH concentrations were from samples collected within the observed asphalt / bitumen waste layer at approximately 0.5 m depth. Lead was detected at a concentration in excess of ANZECC ISQG-High sediment quality guideline values in one sample.

5.4 Asbestos Three pieces of potential ACM were analysed. The presence of asbestos was confirmed in one sample; Test Pit 9 HH-ACM-01, collected from a fragment of suspected ACM pipe.

No asbestos was detected in the 13 soil samples analysed for asbestos.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 16 6.0 Conclusions and Recommendations

6.1 Summary The site is located on land which has been identified as having potentially had the following HAIL activities on site:  A10 – Persistent pesticide bulk storage or use (historical orchard).  A17 – Drums for fuel, chemicals or liquid waste (drums observed onsite).  A18 – Bulk storage of treated timber outside (2014 storage).  E1 – Asbestos products including disposal and buildings containing asbestos products known to be in a deteriorated conditions (associated with former foundry, onsite buildings)  G3 – Landfill site (possible historic landfill)  G5 – Waste disposal to land (associated with filling of the site and current large concrete stockpile).

No analysed contaminants of concern were detected at concentrations in excess of SCS for ongoing commercial land use. With the exception of an ACM pipe encountered in one test pit, no ACM or asbestos fines were detected in the samples analysed during the investigation.

Several heavy metals and PAHs were detected at concentrations in excess of background. PAHs or lead were detected at concentrations in excess of ANZECC ISQG-high criteria in eight samples.

6.2 Recommendations

6.2.1 Contamination Management No analysed contaminants of concern were detected at concentrations in excess of SCS for ongoing commercial land use. Accordingly it is considered that it is highly unlikely that the proposed commercial land use development will present a risk to human health. No further contaminated land assessment or remedial works are considered necessary with regards to evaluation of potential human health risks.

6.2.2 Soil Re-use or Disposal The presence of contaminant concentrations above background excludes disposal of most surplus soils from the site as cleanfill. Surplus soils from the site will require disposal to a licensed disposal facility. Surplus soils requiring disposal should be suitable for disposal to Burwood landfill, subject to landfill acceptance. The exception to this would be lead contaminated soils associated with sample TP14-HH44, and soils associated with ACM pipes that may be present at the site. Such soils will likely require disposal to Kate Valley Landfill.

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 17

Analytical results indicate that deeper, natural soils at the site may be suitable for disposal as cleanfill. However, further sampling and analysis is required to confirm this.

With the exception of lead contaminated soils associated with sample TP14-HH44, and ACM pipes that may be removed, soils excavated during development works are considered suitable for re-use onsite (subject to geotechnical properties, assessment of which are outside the scope of this report). 6.3 Regulatory Considerations (Contaminated Land) Contaminants at concentrations in excess of background were detected. As such Davis Ogilvie considers that the NESCS Regulations do apply to this site. Proposed development soil disturbance / offsite removal volumes will exceed NESCS permitted activity limits and as such application for consent will be required. Contaminant concentrations in excess of industrial / commercial SCS were not detected and accordingly it is considered that application for consent as a controlled activity under regulation 9 of the NESCS will be required.

As contaminant concentrations above background were detected application for consent under Rule 9 of the CCC City plan (Critical Standard 9-5.8.1 (a) Content of fill and excavation material) will also be required.

Lead, zinc and a number of pesticides were detected at concentrations above the ANZECC ISQG-High guideline values. As such, it is considered likely that application for construction phase stormwater discharge consent from ECan will also be required for the proposed site redevelopment works. ECan will determine this on review of this DSI

6.4 Regulatory Considerations (Contaminated Land) Contaminants at concentrations in excess of background were detected. As such Davis Ogilvie considers that the NESCS Regulations do apply to this site.

6.4.1 Subdivision Due to the identified historical HAIL activity on the site the proposed subdivision (amalgamation) could not be conducted as a permitted activity under the NESCS. A DSI exists (this report) that states that soil contamination at the site does not exceed the applicable SCS. As such it is considered that the site meets the requirements for the subdivision to proceed as a controlled activity. Application for consent as a controlled activity is required under Regulation 9(3) of the NESCS.

6.4.2 Soil Disturbance Proposed development soil disturbance volumes are likely to exceed permitted activity criteria calculated on a piece of land basis and accordingly application for consent to

Detailed Site Investigation 330 & 340 Port Hills Road October 2016 Page 18 disturb/remove soils is required. A DSI exists (this report) that states that soil contamination at the site does not exceed the applicable SCS. As such it is considered that the site meets the requirements for soil disturbance to occur as a controlled activity. Application for consent as a controlled activity is required under Regulation 9 (3) of the NESCS.

As contaminant concentrations above background were detected, application for consent under Rule 9 of the CCC City plan (Critical Standard 9-5.8.1 (a) Content of fill and excavation material) will also be required.

6.4.3 Construction Phase Stormwater A number of PAHs were detected at concentrations above the ANZECC ISQG-High guideline values in the bitumen layer at 0.5 m below EGL, as well as in the stockpile. As such, application for construction phase stormwater discharge consent from ECan may be required for the proposed site redevelopment works. ECan will determine consenting requirements on review of this DSI.

The LLUR is a database that Environment Canterbury uses to manage information about land that is, or has been, associated with the use, storage or disposal of hazardous substances. Why do we need the LLUR? Some activities and industries are hazardous and can potentially contaminate land or water. We need the LLUR to help us manage information about land which could pose a risk to your health and the environment because of its current or former land use. Section 30 of the Resource Management Act (RMA, 1991) requires Environment Canterbury to investigate, identify and monitor contaminated land. To do this we follow national guidelines and use the LLUR to help us manage the information. Listed Land The information we collect also helps your local district or city council to fulfil its functions under the RMA. One of these is implementing the National Environmental Standard (NES) for Assessing and Managing Contaminants in Soil, which came into effect on 1 January 2012.

Listed Land Use Register Site categories and definitions

When Environment Canterbury identifies a Hazardous Activities and Industries List (HAIL) land use, we review the available information and assign the site a category on the Listed Land Use Register. The category is intended to best describe what we know about the land use. If a site is categorised as Unverified it means it has been reported or identified as one that appears on the HAIL, but the land use has not been confirmed with the property owner. If the land use has been confirmed but analytical information from the collection of samples is not available, and the presence or absence of contamination has therefore not been determined, the site is registered as: Not investigated: • A site whose past or present use has been reported and verified as one that appears on the HAIL. • The site has not been investigated, which might typically include sampling and analysis of site soil, water and/or ambient air, and assessment of the associated analytical data. • There is insufficient information to characterise any risks to human health or the environment from those activities undertaken on the site. Contamination may have occurred, but should not be assumed to have occurred. If analytical information from the collection of samples is available, the site can be registered in one of six ways: At or below background concentrations:

The site has been investigated or remediated. The investigation or ents post remediation validation results confirm there are no hazardous substances above local background concentrations other than those

EG Y Design and Advertising 2009 has been sufficiently detailed to characterise the site. Below guideline values for: The site has been investigated. Results show that there are hazardous substances present at the site but indicate that any adverse effects or risks to people and/or the environment are considered to be so low as to be acceptable. The site may have been remediated to reduce contamination to this level, and samples taken after remediation confirm this. Managed for: The site has been investigated. Results show that there are hazardous substances present at the site in concentrations that have the potential to cause adverse effects or risks to people and/or the environment. However, those risks are considered managed because: • the nature of the use of the site prevents human and/or ecological exposure to the risks; and/or • the land has been altered in some way and/or restrictions have been placed on the way it is used which prevent human and/or ecological exposure to the risks. Partially investigated: The site has been partially investigated. Results: • demonstrate there are hazardous substances present at the site; however, there is insufficient information to quantify any adverse effects or risks to people or the environment; or • do not adequately verify the presence or absence of contamination associated with all HAIL activities that are and/or have been undertaken on the site. Significant adverse environmental effects: The site has been investigated. Results show that sediment, groundwater or surface water contains hazardous substances that: • have significant adverse effects on the environment; or • are reasonably likely to have significant adverse effects on the environment. Contaminated: The site has been investigated. Results show that the land has a hazardous substance in or on it that: • has significant adverse effects on human health and/or the environment; and/or • is reasonably likely to have significant adverse effects on human health and/or the environment. If a site has been included incorrectly on the Listed Land Use Register as having a HAIL, it will not be removed but will be registered as: Verified non-HAIL: Information shows that this site has never been associated with any of the specific activities or industries on the HAIL.

A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However, no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results (regarding both quality and NATA accreditation).

If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

General 1. Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples are included in this QC report where applicable. Additional QC data may be available on request. 2. All soil results are reported on a dry basis, unless otherwise stated. 3. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences. 4. Results are uncorrected for matrix spikes or surrogate recoveries. 5. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise. 6. Samples were analysed on an 'as received' basis. 7. This report replaces any interim results previously issued.

Holding Times Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001). For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the Sample Receipt Advice. If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported. Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control. **NOTE: pH duplicates are reported as a range NOT as RPD

Units mg/kg: milligrams per Kilogram mg/l: milligrams per litre ug/l: micrograms per litre ppm: Parts per million ppb: Parts per billion %: Percentage org/100ml: Organisms per 100 millilitres NTU: Nephelometric Turbidity Units MPN/100mL: Most Probable Number of organisms per 100 millilitres

Terms Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis. LOR Limit of Reporting. SPIKE Addition of the analyte to the sample and reported as percentage recovery. RPD Relative Percent Difference between two Duplicate pieces of analysis. LCS Laboratory Control Sample - reported as percent recovery CRM Certified Reference Material - reported as percent recovery Method Blank In the case of solid samples these are performed on laboratory certified clean sands. In the case of water samples these are performed on de-ionised water. Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery. Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison. Batch Duplicate A second piece of analysis from a sample outside of the clients batch of samples but run within the laboratory batch of analysis. Batch SPIKE Spike recovery reported on a sample from outside of the clients batch of samples but run within the laboratory batch of analysis. USEPA United States Environmental Protection Agency APHA American Public Health Association TCLP Toxicity Characteristic Leaching Procedure COC Chain of Custody SRA Sample Receipt Advice CP Client Parent - QC was performed on samples pertaining to this report NCP Non-Client Parent - QC performed on samples not pertaining to this report, QC is representative of the sequence or batch that client samples were analysed within TEQ Toxic Equivalency Quotient

QC - Acceptance Criteria RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable: Results <10 times the LOR : No Limit Results between 10-20 times the LOR : RPD must lie between 0-50% Results >20 times the LOR : RPD must lie between 0-30% Surrogate Recoveries: Recoveries must lie between 50-150%-Phenols & PFASs 20-130%

QC Data General Comments 1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within the sample, high moisture content or insufficient sample provided. 2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent and Duplicate data shown is not data from your samples. 3. Organochlorine Pesticide analysis - where reporting LCS data, Toxaphene & Chlordane are not added to the LCS. 4. Organochlorine Pesticide analysis - where reporting Spike data, Toxaphene is not added to the Spike. 5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported in the C10-C14 cell of the Report. 6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time. Analysis will begin as soon as possible after sample receipt. 7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte. 8. Polychlorinated Biphenyls are spiked only using Aroclor 1260 in Matrix Spikes and LCS. 9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample. 10. Duplicate RPDs are calculated from raw analytical data thus it is possible to have two sets of data.

Samples were analysed according to Australian Standard AS 4964 – 2004 including the use of polarised light microscopy with dispersion staining

Results pertain to the sample ‘as received’. In cases where the sample is obviously layered or otherwise non‐homogenous an indication will be given as to the portion of the sample where any asbestos has been identified.

Any chrysotile (white asbestos), amosite (brown asbestos) or crocidolite (blue asbestos) found will be indicated in the report. The presence oforganic fibres (eg vegetable matter or nylon) or SMF (synthetic mineral fibres, eg glass fibre) will also be noted. Other fibres are not conclusively identifiable without additional analysis and will be indicated on the report asUMF (Mineral fibres of unknown type. The fibres may or may not be asbestos.) The reporting limit is 0.1g/kg.

General process and comments: Seven samples of soil was delivered to CRL Energy for asbestos analysis. The samples were air dried and passed through 7mm and 2mm screens. All fractions were visually reviewed and suspect fragments observed with a stereo microscope. A polarising microscope was used to identify any suspect fibres or material. Asbestos in cement board is estimated at 15% mass.

This report is consistent with the analytical procedures and reporting recommendations in the Western Australian Guidelines for Assessment, Remediation and Management of Asbestos contaminated sites in Western Australia ‐ May 2009. (WA Guidelines) Fibre samples detected were analysed according to Australian Standard AS 4964 – 2004 including the use of polarised light microscopy with dispersion staining Results pertain to the sample ‘as received’. In cases where the sample is obviously layered or otherwise non‐homogenous an indication will be given as to the portion of the sample where any asbestos has been identified. Any chrysotile (white asbestos), amosite (brown asbestos) or crocidolite (blue asbestos) found will be indicated in the report. Other mineral fibres not conclusively identifiable without additional analysis and will be indicated on the report as ‘Mineral fibres of unknown type. The fibres may or may not be asbestos.’ The reporting limit recognised under AS 4964 is 0.1g/kg although asbestos concentration indicated may be more sensitive than this as sample size and sample processing methods recommended under the WA Guidelines make these limits meaningful for evaluation of contamination levels.
