Construction Environmental Management Plan CC Stage 1

Project International Chinese School 211 Pacific Highway, St. Leonards NSW

Job No 2417.19 Date Oct 2020 – Rev. B 1.0 Introduction This Construction Environmental Management Plan (CEMP) has been prepared for International Chinese School to address the requirement of the Development’s Condition of Consent and form part of submission for CC documentation. This plan outlines a general approach to environmental management for the site and processes to be implemented for construction of the new school campus. The statements and proposals documented in this plan are compilation of different Construction Environmental Strategies. The Management Plan provides sufficient information to demonstrate potential impacts on the environment with public health and amenity risks identified and to address suitable measures to mitigate impacts prior to and during construction. 2.0 Project Site The proposed site for the new school campus is located on the Pacific Highway known as 211 Pacific Highway St. Leonards approximately 5000m south-west of the St. Leonards Train Station. The site is irregular in shape and has an approximate area of 1,563 m2. The site was formerly the Sexton Cottage for the adjoining Gore Hill Cemetery and has undergone changes in recent years. The proposed new School site is bounded by; the existing Gore Hill Cemetery to the north; the existing Gore Hill Oval to the east; and existing commercial and residential development to the south and west on the opposite side of the Pacific Highway. It has an existing vehicle access link road from the adjoining Council carpark, connecting it to the Pacific Highway.


Site Plan shown below.


3.0 Project Staging The project will be accommodated through a staging process.

• Stage 1 - Basic infrastructure being signage, fencing and minor landscaping works. • Stage 2 - The Avenue kiss and drop and all works related to the council carpark. • Stage 3 - The deceleration lane, fencing and all associated works within the pacific highway

road reserve. 4.0 Context 4.1 Project Details

a. Hours of work The working hours shown below will be implemented in the execution of the project.

Construction, including the delivery of materials to and from the site to be carried out between the following hours:

• Between 7 am and 6pm, Mondays to Fridays inclusive; • Between 8 am and 1 pm, Saturdays • No work to be carried out on Sundays or public holidays

Rock breaking, rock hammering, sheet piling, pile driving, and similar activities (if any) to be carried out between the following hours:

b. 24-Hour contact details of site manager

The Site Manager for the project is Paul Peterkin. Company name: Logic DB Pty Ltd Email: [email protected] Mobile no: 0412 646 535

c. Management of dust and odour to protect the amenity of the neighbourhood

The scope of Stage 1 involves minor works. It will be unlikely to affect public amenities and cause public nuisance as far as the dust and odour.

Dust and odour coming from the actual construction work will only be minimal. The traffic that will be generated from the execution of the work will not be imposing and unlikely to pose drastic effect and disturbance to the public.

A Strategy that will be implemented includes maintaining a good housekeeping practice to limit the effect of dust and odour to adjoining facilities. Keeping the site tidy and free of excessive quantities of construction material and debris will be addressed to minimise the impacts of wind-borne dust, debris and litter. Excess quantity will unlike to occur since only minor work is involved.


In regard to on-site vehicular movement, care will be undertaken for vehicles leaving the premise. In the event for a construction vehicle will cause dust emission issue, washing vehicle wheels before they leave the premise can assist with the dust control. When transferring or transporting materials, they will be covered or contained. In order to minimise and manage the effect of dust and odour an appropriate work scheduling process will be implemented. Dust generating activities will be executed during the most favourable weather conditions such as non-windy day. Likewise, odour generating activities or use of odour causing equipment will be performed during the least sensitive time of the day and under favourable weather conditions. In order to address concerns on the effect of dust and odour on site, monitoring of complaints from neighbours and community will be carried out. Refer to Section 5 of the Report for management of Unexpected Contaminants.

d. Stormwater control and discharge

An overall plan of erosion and sediment control for Construction has been prepared as part of the Construction Environment Management Plan. Refer to Attachment A – Soil & Water Management.

e. Materials excavated and removed from the site classified in accordance with

EPA Waste Classification Guidelines prior to disposal to NSW approved landfill site

Stage 1 does not require materials removed from site. In the event that this occurs, which is unlikely to take place, adherence to appropriate classification in accordance with EPA Waste Classification Guidelines would be followed. For additional information refer to Attachment B – Stage 2 Detailed Site Investigation prepared by AIRSAFE. Refer to Section 5 of the Report for management of Unexpected Contaminants.

f. Measures to ensure that sediment and other materials are not tracked onto the

roadway by vehicles leaving the site Soil & Water Management Plan has been prepared addressing the measures

undertaken to ensure that sediment and other materials are to be maintained within the site. Refer to Attachment A – Construction Soil & Water Management.

g. External lighting in compliance with AS 4282-2019 Control of the obtrusive

effects of outdoor lighting The development has exercised and adapted reasonable steps to minimise

environment harm or environmental nuisance including any pollution caused by external lighting. The external lighting has been designed to comply with AS 4282-2019. Refer to Attachment C - Electrical Certificate.

h. Community consultation and complaints handling

The International Chinese School has prepared a Community Notification Letter which informed neighbours and nearby establishments regarding the development.


The letter had been distributed through letter box drop. The Notification letter provided relevant information regarding the proposed program of construction, staging, contractors contact details for Stage 1 and the School’s contact details in order to accommodate feedbacks on the development.

4.2 Interim Management / Mitigation Measures to be implemented while the drop-off/ pick-

up zone in The Avenue, the vehicular access loop road and public carpark are undertaken concurrently with the operation of the school within 211 Pacific Highway, St. Leonards

An Interim Management / Mitigation Measure Plan has been prepared for the project. Refer to Attachment D

4.3 Construction Waste Management Sub-Plan

A Construction Waste Management Plan has been prepared for the project. Refer to Attachment E.

4.4 Construction Soil and Water Management Sub-Plan

A Construction Soil and Water Management Plan has been prepared for the project. Refer to Attachment A.

4.5 Unexpected Finds Protocol for Aboriginal and non-Aboriginal (historic)

The subject site has a historical significance. It has been listed in Schedule 5 of the Willoughby LEP 2012 and is listed on the NSW State Heritage Register. A procedure has been put in place to address unexpected historic finds which have aboriginal and non-aboriginal significance.

a. Unexpected Finds Protocol Aboriginal Heritage

In the event of discovery of Aboriginal objects or bones suspected of being human are identified during construction, site workers must:

(i) not further disturb or move these remains; (ii) immediately cease all work at the location; (iii) in the case of suspected human remains only, notify NSW Police Force; and (iv) in the case of Aboriginal objects, notify Coast History & Heritage (or any other

suitably qualified person) and the Metropolitan Local Aboriginal Land Council to organise recording and collection of the objects.

(v) recommence works only with the written approval of Heritage NSW. (vi) register the site on the Heritage NSW AHIMS register. (vii) determine management of any collected Aboriginal archaeological remains in

consultation with the Registered Aboriginal Parties to the project, as outlined in the Aboriginal Cultural Heritage Report, prepared by Coast History and Heritage, dated August 2019.

b. Unexpected Finds Protocol Historic Heritage

If any unexpected archaeological relics are uncovered during the work:


(i) all works must cease immediately in that area and Heritage NSW must be notified in accordance with section 146 of the Heritage Act 1977 (NSW).

(ii) depending on the possible significance of the relics, an archaeological assessment and management strategy may be required before further works can continue in that area.

(iii) works may only recommence with the written approval of Heritage NSW. 4.6 Waste Classification and Validation

The works included for Stage 1 do not include removal of materials on site. Only minor works will be involved. This will include provision of signages, fence, minor landscape work including provision for new external stairs and remediation work to stair handrails to accommodate Class 9b. Refer to Section 5 of the Report for management of Unexpected Contaminants.

5.0 Hazardous Materials: Unexpected Contaminants

(relates to Conditions of Consent C5 & C20b) 5.1 Introduction

The purpose of this Statement relates to Hazardous Materials and addresses relevant procedure and methodologies for Unexpected Finds that will need to be applied as part of the Development.

This report provides supplementary information to the Construction Environmental Management Plan and relates to Conditions C05 and C20(b) of the conditions of consent for the Stage 1 building works.

5.2 Site investigation results (Consultant: AIRSAFE, 93 Beattie Street, Balmain, NSW, 2041)

AIRSAFE were engaged to assess the presence of hazardous materials, refer to included report Stage 2 Detailed Site Investigation (Ref.02787.08.19.Stage2DSI.REV .1). Within this report the soil sample laboratory analysis results confirm that metals analysis results did not exceed the HIL A criteria f in accordance with the NEPM 2013. Further, they did not exceed the Ecological Investigation Levels (EILs) or Ecological Screening Levels (ESLs). (AIRSAFE report p.9)

No asbestos fibres were detected within the soil at reporting limit of 0.1g/kg, and no respirable fibres detected in the samples analysed. A small bundle of fibres were detected in sample 02787/BH1/0.1 (Airsafe-46809- 10). The measured weight of the bundle was 0.0012 g. The total weight of the sample media was 725.7 g. The estimated FA and AF (w/w) was 0.000165%. This w/w was below the NEPM health screening level of 0.001%. (AIRSAFE report p.9)

5.3 Unexpected Finds Protocol – Asbestos

Refer Appendix A to this report. Airsafe, who prepared the Detailed Site Investigation, has prepared the Unexpected Finds Procedure - Asbestos.

5.4 Unexpected Finds Protocol – General


All site personnel are required to report to the Site Manager any signs of unexpected environmental concern such as presence of petroleum or other chemical odours, unexpected fibre cement, unnatural staining, potential contamination sources or chemical spills. Indicators of possible contamination in soils include but are not limited to; • Discolouration of soils, including staining and horizontal layers of discolouration • Odours from soils • Oily sheen on water leaving soils • Foreign objects/evidence of landfilling

As soon as practical, in the occurrence that any sign of concern has been identified, the Contractor will observe the following:

Step 1 – Potential contamination encountered • Place barricades around the affected area and cease work in that area; • Install environmental controls around the site to contain the contaminated material,

including as necessary the diversion of water to minimise potential spread via surface water runoff.

• If it is determined that there is a risk of environmental harm from the potential contamination, the EPA will be notified immediately.

Step 2 – Work, Health and Safety (WHS) • Prior to any contamination investigation, management or remediation activities, safe work

method statements will be prepared. • Relevant Personal Protective Equipment (PPE), as identified in Material Safety Data

Sheets, will be worn. This may include, but not limited to; o Respirator/face mask. o Rubber gloves. o Rubber boots. o Eye goggles.

Step 3 – Site/area contamination investigation • The head contractor will notify the Contract Superintendent and the qualified

contamination specialist firm, AIRSAFE, to conduct a contamination investigation in the area of the find.

• The material will be classified in accordance with the Waste Classification Guidelines (EPA, 2014).

• If deemed necessary, the Contract Superintendent will liaise with the relevant authorities to determine appropriate management strategies.

Step 4 – Remedial action The Head Contractor in consultation with AIRSAFE, will develop a remediation action plan and implement determined management measures in accordance with guidelines contained within the Contaminated Land Management Act (NSW). This may include leaving contamination undisturbed, capping of contaminant, treatment or disposal offsite at an appropriately licensed waste facility.

It is noted that, the Contract Superintendent must advise the Planning Secretary at the Department of Planning (refer condition of consent C5), if removal of the contaminated material is required prior to commencement of the remediation works.

Step 5 – Recommence works The head contractor is to provide written confirmation that the remediation works have been completed in accordance with the remediation action plan, along with a report outlining the steps undertaken above and the method, location and certification of disposal, to the Contract Superintendent, prior to the recommencement of works.


5.5 Other possible contaminants

While asbestos is the most likely (although not expected) contaminant, other possible contaminants and appropriate actions should they be found, appear in the table below:

CONTAMINANT Comment Mitigation/disposal Lead (paint) • No repainting of surfaces

included in the project. • As the original building was

constructed in the 1980s, it is unlikely as lead-based paint ceased to be manufactured in Australia in 1970.

• Possible small remnants of lead-based paint in soil.

• Avoid any abrasive blasting or water jet treatment of suspected lead-based paint surfaces.

• Tradespersons to have Work Safe Practice documentation in place.

• Contaminated soil to be double bagged and disposed of at appropriate hazardous waste tip.

Acid Sulfate Soil and Rock

Very unlikely given the location of the site, and the minimal excavations required for fence post holes.

• Treat spoil with limestone. • Not to be reused onsite. Acid sulfate

soil can only be disposed of or re-used on sites that have an EMP approved by the EPA or at a landfill with the appropriate licence.

Metals Airsafe testing revealed levels did not exceed EIL or ESL.

Avoid further disturbance. Removal and disposal by qualified and licenced professional to EPA approved site, licenced to accept waste containing heavy metals.

Gases and Vapours

Very unlikely given the minimal excavations required for fence post holes.

• Gases and vapours would likely dissipate as all construction is in open space.

• Identify presence of underground gas services through appropriate searches.

• If services are damaged and gas leak suspected cordon off the work site and dial ‘000’.

Chemical Workers involved with excavation activities may be exposed to particulate matter contaminated with semi-volatile organic, and/or inorganic contaminants. Inhalation hazards are particularly evident during warm and dry periods when there is a greater chance for airborne dusts to be generated.

Controls include: • Proper types of personal protective

equipment (PPE) and their use. (eg. nitrile gloves for dermal exposure to gasoline, an air-purifying respirator equipped with approved filter/cartridges

• Use of suitably qualified & experienced worker

• Dust and other emissions should be suppressed using water or foam suppressants if needed. (Note: Workers should not walk on areas to which foam has been applied).

5.6 Air monitoring

In the event that asbestos or other hazardous material is encountered, the construction work will cease. For asbestos and other airborne hazardous material, air monitoring will be implemented.

Air monitoring devices would be kept at locations identified by a nominated Occupational Hygienist and within the extent of the work area boundaries. Filters to air monitoring will be checked regularly for presence of asbestos fibres and/or other airborne hazardous materials. If contamination has been detected during the course of works, all work will cease and dust


prevention measures will be adapted and improved. This will be addressed in consultation with the Occupational Hygienist.

5.7 Measures and Safeguards to Control Emission of Fibres

Appropriate measures will be adapted during the Construction works to manage emission of fibres and control air quality by minimising the release of emissions to the atmosphere during construction.

Mitigation and control measures will be used to assist in controlling dust exhaust emission and maintaining air quality: • The primary method for controlling fibre emission/dust will be water sprayed by water

tankers or hand spraying of water. An adequate supply of water should be made available for dust suppression activities. During working hours, water sprays will be used to keep the surface of work areas and stockpiled soils, which will be kept to a minimum, reasonably damp to suppress dust. Water spray dust suppression will be kept to the minimum required and will not be allowed to escape the confines of the work areas. If excessive dust is being generated, works will cease until the dust is appropriately suppressed and controlled.

• Stockpile heights are to be maintained to a minimum as much as possible. Stockpiles are to be oriented and located in areas that limit exposure to adverse wind conditions and away from sensitive receptors.

• Where practical, dust producing activities during adverse weather conditions such as dry and/or windy condition will cease when uncontrollable dust emissions are directed towards sensitive receptors.

• Vegetation clearing and earthworks will be restricted to the minimum areas necessary. • Trucks importing or removing fill from site shall be covered at all times or sprayed with

water prior to leaving the site. • Any mud, sand or spilt onto internal roads are to be cleaned and removed daily. • Weather conditions will be monitored and work methods will be adjusted accordingly as

required • All plant and machinery involved in the construction works to be regularly serviced and

checked for exhaust emissions 5.8 Disposal of Material

All materials excavated and removed from the site shall be disposed in accordance with the POEO Act (Protection of the Environment Operations Act 1997 No 156) to a facility /site legally able to accept the material. Copies of all necessary approvals from the receiving site shall be provided prior to any contaminated material being removed from the site. A record of the disposal of materials will be maintained and issued to the Contract superintendent.

All relevant analysis results shall be made available to enable selection of a suitable disposal location.

To ensure compliance an authorised Waste Contractor will be engaged to collect and dispose of the hazardous waste in accordance with the Waste Tracking guidelines set down by the NSW Environmental Protection Authority. The nominated Waste Contractor will attend the site should hazardous waste be identified. Due to the waste tracking system as set by the Environment Protection Authority, the collection process will include a full summary of hazardous waste collected and each category of waste will be recorded. The Waste Contractor is required to dispose of the waste following the EPA Waste Tracking Guidelines, and forward copies of all handling and disposal dockets with their invoice for services to EPA including a statutory declaration that all wastes have been disposed of in the appropriate manner.


Copies of all consignment notes for the transport, receipt and disposal of all materials (including VENM) will be maintained as part of the site log and made available to the Environmental Consultant for inspection and reporting purposes upon request.
