Bulk Earthworks Contaminated Land Management Plan

1 Introduction

2 42788090/R001/E

This draft BECLMP provides procedures for management of contaminated soil and other materials

potentially present in ground that may be disturbed or require removal to complete the Project.

1.2 The Project

1.2.1 Main alignment

The Project is one of eight sections of the Wellington Northern Corridor RoNS that runs from

Wellington Airport to Levin. The completion of the Wellington Northern Corridor RoNS will assist

regional and national economic growth. . The location of the Project in the overall scheme of this

corridor is illustrated in Figure 1-1 below.

The NZTA proposes to designate land and obtain the resource consents to construct, operate and

maintain the Peka Peka to North Ōtaki section of the Wellington Northern Corridor RoNS. This Project

extends from Te Kowhai Road in the south to Taylors Road just north of Ōtaki, an approximate

distance of 13 km.

The Peka Peka to North Ōtaki Expressway section of the Wellington Northern Corridor RoNS will

provide an expressway with two lanes of traffic in each direction. Connections to local roads, new

local roads and access points over the expressway to maintain safe connectivity between the western

and eastern sides of the expressway are also proposed as part of the Project. There is an additional

crossing of the Ōtaki River proposed as part of the Project, along with crossings of other watercourses

throughout the Project length.

On completion, it is proposed that the expressway becomes State Highway 1 (SH1) and that the

existing SH1 between Peka Peka and North Ōtaki become a local road, allowing for the separation of

local traffic. It is noted that the power to declare roads to be State Highways or revoke status resides

with the Chief Executive of the Ministry of Transport, not with the NZTA.

1.2.2 NIMT

KiwiRail proposes to designate land in the Kāpiti Coast District Plan for the construction, operation and

maintenance of a re-aligned section of the North Island Main Trunk (NIMT) through Ōtaki.

2 Summary of Potentially Contaminated Sites

6 42788090/R001/E

Table 2-2 Summary of Findings of the Site-Specific Phase 1 CLAs

Site Findings of Phase 1 CLAs Otaki Station & Sidings There is potential for ground contamination associated with the railway current and

historic maintenance and operational activities on the Ōtaki Station and Sidings properties. Staining of rail ballast around the railway tracks was observed during the site walkover, but no other evidence of surface soil contamination. Contaminants including petroleum hydrocarbons and metals are expected to be present. Records indicate the presence of a gas house; however the location of the gas house is unknown. The exact nature and use of the gas house has not been determined. Former and current buildings/structures within the boundaries of the properties included a goods shed, amenities block, Otaki Station building, men's toilets, septic tank and other undefined structures. Other potential sources of historic contamination were identified along the rail corridor to the south west outside the confines of the Otaki Station and Sidings properties. These included potential stock holding yards, a train turn-table area, potential wood storage area and associated buildings. Based on the potential HAIL activities identified at the site the following potential contaminants of concern maybe present within the proposed Project corridor: hydrocarbons, PAHs, heavy metals, solvents, creosote, metal and asbestos particulates associated with braking, fuel (diesel), lubricating oils, grease associated with spills/leaking, arsenic, organochlorines (e.g. aldrin, dieldrin, DDT4, lindane), organophosphates, carbamates, synthetic pyrethroids, biological hazards (bacteria, viruses) and PCP.

Winstone Aggregates No potential sources of ground contamination were identified within the designated Project corridor. However, sources of potential ground contamination were identified on the Winstone Aggregates site, immediately west of the designated Project corridor, and include:

storage of grease, oil and paint;

asbestos on the inner wall cladding of the old store;

three waste oil aboveground storage tanks; one aboveground diesel storage tank; location of former underground diesel storage tank;

septic tanks; and,

an electrical transformer.

Mary Crest Potential sources of ground contamination within the designated Project corridor include:

Former farm operations on the southwest portion of the property, including

foundations of former farm structures and an uncharacterised ground depression.

Potential for a septic tank located within the vicinity of the dwelling at the entrance

to the Mary Crest site.

There is also potential for ground contamination outside the designated Project area but within the confines of the Mary Crest site, including underground storage tanks (locations unconfirmed) and former farm operations. Based on the potential HAIL activities identified at the site the following potential contaminants of concern maybe present within the proposed Project corridor: heavy metals, wide range of organic agrichemicals including organochlorine pesticides,

2.4 Sites of Potential Concern for Contaminated Land In addition to the sites/areas identified above additional sites were identified within the designated

Project corridor in the Phase 1 CLA as sites of potential concern for contaminated land. A summary of

these sites is provided in Table 2-4 with a cross reference to the property ownership reference

numbers shown on Figure 2-1 through Figure 2-6. These sites are inferred to have lower risk for land

contamination than those identified above. Specific procedures for management of contaminated land

have not been developed for these sites; however, they would be reviewed and/or assessed prior to

initiating physical works within these sites/areas and general/site-specific management measures

implemented should contaminated land or materials be discovered (refer Section 3).

3 Management of Contaminated Soil and Other Materials

18 42788090/R001/E

Site Proposed Contaminated Material Management Procedures Market Garden Sites Assess soil that may be impacted by the proposed works.

Obtain Territorial Authority consents as required.

Material (including contaminated material) assessed as suitable may be left in place.

Remove and dispose of contaminated material offsite as determined by the assessment or as required by the proposed works.

3.2 Contaminated Sites Identified During Works Previously unidentified contaminated soils or other materials may be discovered during the works.

Given the nature of the Project corridor it is anticipated that such discoveries would most likely be

associated with the following:

Farm tips and offal pits

Storage, handling and use of herbicides and pesticides

Septic tanks

Heating oil and/or fuel storage in underground tanks

Sheep dips

Market gardens and orchards

The Users’ Guide National Environmental Standard for Assessing and Managing Contaminants in Soil

to Protect Human Health6 provides a list of constituents of potential concern associated with specific

activities and industries. An excerpt from this list is provided in Table 3-2.

Table 3-2 Summary of Constituents of Potential Concern for Some Potential Activities within the Project Corridor

Activity/Industry Constituents of Potential Concern

Agrichemicals including commercial premises used byspray contractors for filling, storing or washing out tanks for agrichemical application

3.2.3 Initial Actions

Upon discovery of potential contaminated soil or other material, the following preliminary measures

shall be undertaken:

Assess potential immediate hazards, if unsafe move away, and upwind from area

Notification of potential discovery as described above

(If assessed to be safe, the following shall be undertaken) Make area and works in progress safe

Stop works in and adjacent to the inferred area of contaminated soil or materials

Secure/isolate area

Implement temporary measures to minimise transport of potential contaminants offsite

3.3 General Procedures for Management of Contaminated Soil and other Materials

Indicative general procedures for management of contaminated soil and other materials are provided

below. It is anticipated that these procedures would be reviewed and updated as appropriate, when

site/area and contaminant specific details and the proposed construction methodologies are known.

3.3.1 Assessment

An assessment of the potentially contaminated soil or other material shall be undertaken by a suitably

qualified and experienced practitioner11. Such assessment shall be based on the following, as

appropriate:

The hierarchy set out in the Ministry for the Environment “Contaminated Land Management

Guidelines No. 2”, 2011

Ministry for the Environment “Guidelines for Assessing and Managing Petroleum Hydrocarbon

Contaminated Sites in New Zealand”, Revised 2011

Resource Management (National Environmental Standard for Assessing and Managing

Contaminants in Soil to Protect Human Health) Regulations 2011 (NES)

Contaminated Land Management Guidelines No.5: Site Investigation and Analysis of Soils, Ministry

for the Environment (2011)

Identifying, Investigating and Managing Risks Associated with Former Sheep-dip Sites: A guide for

local authorities, Ministry for the Environment

Soils or other materials assessed as not suitable to remain in situ, based on the proposed landuse and

the proposed works, shall be removed offsite for treatment and/or disposal.

It is anticipated that appropriate assessment may conclude that contaminated soils and other

materials may be left in place. It is anticipated that covering/capping of ground contamination, as

would occur with the road construction associated with the Project, may be the most practical and

suitable solution for mitigating effects of ground contamination.

It is also anticipated that some soil and/or other materials assessed as suitable to remain onsite may

be removed for offsite treatment and disposal due to conflicts with the proposed Projector because

they are geotechnically unsuitable.
