Guide for the Re-use or Disposal of Surplus Soil

1.0 PURPOSE

This document provides guidance to DPTI staff on the appropriate re-use or disposal of surplus soil, to ensure that adverse effects on human health and the environment are avoided, and works are carried out in accordance with the Environment Protection Act 1993.

Refer to Operational Instruction 21.6 ‘Recycled Fill Materials for Transport Infrastructure’ for full details and legislative context.

This document is not intended for use in emergency situations. In the event of a spill (eg as the result of a vehicle collision or equipment failure): Appropriate steps must been taken as soon as possible to contain the spill and minimise environmental or human harm (including cleaning any debris/ material from the road surface). DPTI staff and/or emergency services personnel may undertake these tasks. DPTI officers should not get involved in excavating and disposing of contaminated soil. DPTI is not licensed to transport or store contaminated soil. If requested to assist with excavation and disposal, the officer attending the incident should call the EPA emergency response team on 8204 2004 of 1800 623 445 (non-metro callers). The EPA’s authorised officers can advise on the next steps and provide suggested companies to manage the clean-up. If the person who caused the incident is unable to make the necessary arrangements, the EPA will do so on their behalf and recover the costs.Further information on responding to spills at DPTI depots is found in knet #9605054.

2.0 SCOPE

This procedure applies to the handling of surplus soil by DPTI staff and contractors.

It does not apply to organisations external to DPTI.

It does not apply to other materials such as asphalt planings or rail ballast (for information on the re-use and disposal of these materials, refer to DPTI Operational Instruction 21.6 – “Recycled Fill Materials for Transport Infrastructure” (knet 1003752) and “Guide for the Re-use or Disposal of Asphalt Planings” (knet 5876413).

Section 5 provides a flow-chart of the procedure for re-use of surplus soil.

Section 6 provides a flow-chart of the procedure for the disposal of surplus soil.

Information on stockpiling is provided in section 7.0.

A template for an internal risk assessment for potential contamination is provided in Appendix 3.

4.0 KEY POINTS DETERMINING WHEN SAMPLING IS REQUIRED AND WHEN AN EPA LICENCE IS REQUIRED Contamination sampling IS required:

- when there is a history of potentially contaminating activities on (or immediately adjacent) the site.

- whenever there are visual/ olfactory indicators of contamination.

- when disposing of material to a licensed waste facility (dependent on the conditions of the waste facility’s EPA licence).

- when giving soil away to a third party (eg a landowner or Council). Surplus fill material may be passed on to a third party (eg a landowner or Council) only if it has been sampled and it meets Waste Fill criteria and a formal agreement has been signed by the third party, acknowledging suitable re-use options and accepting liability for the material.

- when changing the use of a piece of land to a more sensitive use, ie one where there is greater risk of people being exposed to contaminants (eg rail corridor to recreational trail)

Contamination sampling is NOT required:

- when re-using any amount of soil within the same site, and there is no reason to believe the material may be contaminated, eg the soil comes from a site where no potentially contaminating activities have been carried out, and there are no visual/ olfactory indicators of contamination.

- when re-using <100 tonnes of soil at another site within the DPTI network, and there is no reason to believe the material may be contaminated, eg the soil comes from a site where no potentially contaminating activities have been carried out, and there are no visual/ olfactory indicators of contamination.

- when re-using >100 tonnes of soil at another site within the DPTI network and DPTI’s Site Contamination Officer has provided a minute stating that the risk is low.

- when re-using or disposing of any amount of clean concrete (not containing soil material)

- when re-using any amount of engineered aggregate within the DPTI network (sampling is not required because engineered aggregate is a known material which has been imported in accordance with DPTI Pavement Specification and has already been subject to QA procedures)

An EPA licence IS required to store surplus soil or other waste material at a site other than where it was produced or where it will be re-used (eg at a depot). Note that storage of small amounts of neat asphalt planings (not mixed with road base or soils) is considered low risk and is permitted at DPTI depots, provided quantities are kept below 100t at any one time.

An EPA licence IS NOT required to temporarily* store surplus soil or other waste material at the site where it was produced or where it will be re-used.

*Temporarily means up to 6 months

1. A template for an internal risk assessment of potential contamination is provided in Appendix 3. The internal risk assessment is not as exhaustive as a Phase 1 site history, and should be used as a first pass risk assessment only. If there is any reason to believe that the site may be contaminated, a more detailed assessment should be undertaken, including sampling if appropriate.

2. A Phase 1 site history should follow the procedures detailed in the Assessment of Site Contamination NEPM 1999 with particular reference to Schedule B(2), as follows to the extent required for the potential risk:- A historical search of Lands Titles records for the current Certificates of Title;- A review of aerial photographs for the site and surrounding area;- EPA Section 7 searches for each of the current Certificates of Title;- A review of the local geology and hydrogeology;- A search of the PIRSA database for information regarding registered groundwater bores;- A search of the dangerous goods register;- Determination of the current council zoning and complying developments/development

restrictions for the area within which the site is located; and - A review of any available (relevant) records held by the local council.- An inspection of the site and its immediate surrounds.

3. The Environment Group can arrange for sampling and classification of material.The sampling should be undertaken before the material is taken off site. If there is no room to stockpile the material at the site, it may be taken to an appropriately licensed waste or recycling depot (either a commercial facility or one operated by DPTI) until it has been classified.

4. Re-use of surplus soil that exceeds Waste Fill criteria triggers the need to engage an accredited Site Contamination Auditor. Material up to Intermediate Waste Fill level may be re-used within certain areas of the DPTI network (outlined in Table 1), provided an auditor has endorsed the proposed use and has signed off on a site management plan which documents how the risks associated with the handling and use of the material will be managed.

Unsealed applications within DPTI network, excluding the following areas:- Groundwater is known

to be less than 1m below the ground surface in the area of the project

- The site within 100m of a surface water body, creek or river

- The site is located adjacent to a reservoir

- The site is located within 100m of residential properties or schools (including Day Care Centres and Pre-Schools)


A suitably qualified contamination consultant must prepare a site contamination report verifying that the material is suitable for the intended use. This report must be endorsed by a site contamination auditor prior to transport to the site.

The site contamination auditor must prepare an Audit Report for lodgement with the EPA following re-use of the material.

A licensed waste transporter must be used to transport the material (if material is to be transported on a public road)

Low level contaminated soil

No use permitted within DPTI network. Material must be disposed of to a licensed landfill facility or retained and managed on site

Follow Auditor advice Details must be recorded on

recycled materials database.

High level contaminated soil

No use permitted within DPTI network. Material must be disposed of to a licensed landfill facility or retained and managed on site

Follow Auditor advice A high level waste treatment

plan must be approved by the EPA before high level waste is removed from site

1

1. It is usually preferable to sample material in-situ, ie before excavation work begins. This gives you the information you need to determine disposal options in advance, and avoids the need for double-handling and stockpiling excavated material whilst waiting for test results.

2. Landfill operators are obliged to request a classification report prior to accepting more than 100t of soil from a non-domestic source.

The licensed waste transporter should complete a waste tracking form detailing the nature, source and destination of the material.

3. An example of a written agreement between DPTI and recipients of waste fill can be found at knet 7397945.

4. Unclassified surplus soil, or soil that exceeds Waste Fill criteria should not be passed on to private land-owners, due to the potential for DPTI to be held liable for any harm to the environment or human health resulting from the use of the material.

5. Depending on the landfill facility’s licence conditions, the operator may require a classification certificate before accepting the surplus soil.

7.0 STOCKPILING FOR RE-USE Stockpiling at the source site or re-use site : If surplus soil is to be temporarily* stockpiled at

the site where it was produced or the site where it is to be re-used, no licence is required. Note that contaminated or potentially contaminated material should not be stored on the road network unless public access to the material is restricted and appropriate management measures are in place (see guidelines below).

Stockpiling at a site other than the source site or re-use site (eg at a Field Services Depot or on other land): If >100tonnes/year of surplus soil is to be stockpiled at a site other than where it was produced or where it will be re-used, a licence or limited purposes determination will be required from the EPA – see below:1. If the soil has a direct re-use and is to be temporarily* stockpiled, the EPA may issue

a limited purposes determination for the activity. Contact the Environment Group to organise the limited purposes determination.

2. If the soil is to be stockpiled for more than 6 months or the life of the project, then a licence will be required from the EPA. Contact the Environment Group to organise the licence.

For good stockpile management, refer to the guidelines below.

* Previous interpretations of ‘temporary’ storage suggest a maximum of 6 months or the life of the project. However, if the construction schedule is such that the material needs to be stored for longer, seek advice from the EPA regarding the need for a licence or limited purposes determination.


GENERAL STOCKPILE MANAGEMENT GUIDELINES Different types of material should be kept separate, for example, asphaltic concrete planings

should not be mixed in with soil or other products

All staff should be made aware of the importance of keeping materials with different contamination status separate.

Material of unknown contamination status which is awaiting sampling must be bunded and kept separate from other material until it has been sampled and classified.

If contaminated or potentially contaminated material is to be stockpiled, an appropriate impermeable base will be required to prevent leaching of contaminants into groundwater.

Any stockpile of contaminated or potentially contaminated material should be accurately identified on a site plan or by labelling on-site with a stake or similar. The stockpile should be identified with its source location, type of material contained in the stockpile, contamination status (eg awaiting classification), estimated volume, and the date it was stockpiled.

Stockpiled materials should have a planned use and should not be stored at the stockpile site indefinitely

Appropriate sediment and erosion control measures should be implemented on the site.

The site should be secured, and access controlled to prevent illegal dumping and public from entering the site.

If an EPA licence is required to stockpile the material, a site-specific Environmental Management Plan (EMP) will need to be prepared prior to stockpiling activities commencing. The above requirements should be incorporated into the EMP. An example is provided in Appendix 2.

Guide for the Re-use or Disposal of Surplus SoilAPPENDIX 3: TEMPLATE FOR BASIC RISK ASSESSMENT

This risk assessment template may be used as a guide to determine the likelihood of encountering contaminated material. Note that it does not represent a full Site History Investigation (as described in the National Environment (Assessment of Site Contamination) Measure). If there is any reason to believe that contamination may exist, or if the material is intended for use at a more sensitive site, engage DPTI’s environmental contamination officer or a qualified site contamination consultant to undertake a site assessment.

CONTAMINATION RISK CHECKLIST COMMENTS / OBSERVATIONS

Is the land use changing to a more sensitive land use?Is the soil intended to be re-used for a more sensitive land use?

Road reserves are not considered sensitive land uses because the likelihood of people coming into contact with the soil is relatively low. However, the likelihood of exposure (and potential for health impacts) increases on land used for residential or recreational purposes (eg walking trails, playgrounds), land used for food production, and land which is part of a watercourse or floodplain. Check whether the site will be used for any of these land uses (or other sensitive land uses), or if the soil will be re-used on land used for these purposes.

Are there any records of known site/ groundwater contamination in the immediate area?

Check the EPA’s Site Contamination Groundwater Notification Index: http://www.epa.sa.gov.au/what_we_do/public_register_directory/site_contamination_index

Does the current zoning for the land and adjacent properties suggest that potentially contaminating activities may be permitted?

Check the local Council Development Plan, or Atlas SA: http://www.atlas.sa.gov.au

Does the historical zoning of the land and adjacent properties suggest that potentially contaminating activities were permitted?

Contact the local Council to obtain backdated copies of the Development Plan to check historical zoning.

Is there any staining from leaks or spills, or any other visual or olfactory indicators of site contamination?

Use your own observations, and also check if any geotechnical tests have been done for the project. If so,


http://www.atlas.sa.gov.au/

http://www.epa.sa.gov.au/what_we_do/public_register_directory/site_contamination_index

http://www.epa.sa.gov.au/what_we_do/public_register_directory/site_contamination_index


ask about the soil profile.

Are any potentially contaminating activities occurring on or adjacent the site?

Check appendix 1 of this document or refer to Schedule 3 of the Environment Protection Regulations 2009 for a full description of each activity

Use your own observations or check the ‘generalised land use’ layer and ‘industrial database’ layer on Atlas SA: http://www.atlas.sa.gov.au (both of these are found in the ‘Land Management’ set of layers)

Have any potentially contaminating activities occurred on or adjacent the site in the past?

Check historical aerial photos, accessed through MapLand (for a fee).

Check Adelaide’s former tram network (knet 9373665)

Historical importation of fill for road construction is not listed as a PCA, however, importation of contaminated material has been known to occur in the past. Check any available records of road pavement construction/ rehabilitation

Have there been under-ground or above-ground storage tanks on the property?

Contact SafeWork SA to find out if any dangerous substances have been stored on the property in the past.

Is there any evidence of dumping (eg mounds of soil or other material)?

If any of the above questions are answered YES, contact DPTI’s environmental contamination officer to discuss the level of risk and potential need for further site assessment.

If all of the above questions are answered NO, then the risk of encountering site contamination is considered low.

Note that the SA EPA’s Standard for the Production & Use of Waste Derived Fill (the WDF Standard) recommends that all surplus soil material be sampled and classified prior to being taken off site. Whilst it is not mandatory to follow the WDF Standard, it is the surest way of ensuring that no environmental harm will result from the reuse of the material. If reuse of unclassified material results in environmental harm, there is a chance that DPTI may be found to be in breach of the Environment Protection Act and may be required to remediate any damage.

Advice received from Crown Solicitors Office is that material should always be sampled and classified prior to being given to a third party (eg an adjacent landowner), to reduce DPTI’s liability if the reuse of the material caused harm to the environment or human health.

http://www.atlas.sa.gov.au/

http://www.legislation.sa.gov.au/LZ/C/R/ENVIRONMENT%20PROTECTION%20REGULATIONS%202009.aspx


The following additional precautions should be taken to further reduce the risk associated with reuse/ disposal of the material:

If visual or olfactory indicators of contamination are observed during works, work should cease and advice sought from DPTI’s contamination specialist or a qualified contamination consultant

Include any other precautions here
