Australian Rail Track Corporation (ARTC) is seeking submissions from competent contractors for Implementation of Interim Controls: Goulburn Wheat Yards and Junee Roundhouse.

Scope of work:

Goulburn Wheat Yards

The Proponent is to implement and maintain all of the controls outlined in both the provided ESCP and TMP and undertake ongoing inspections and minor maintenance for a period of 12 months after the initial site works are complete.

Monthly inspections for a period of 12 months from the date of the first round of field works are required along with associated reporting for both the Traffic Management Plan and the Erosion and Sediment Control Plan. An allowance is required for maintenance and inspection of the controls implemented.

Any ground disturbance in areas of high lead concentrations will require lead risk work controls to be outlined in your SWMS and implemented on site. This is to be done in conjunction with a qualified Occupation Hygienist.

An initial site visit is to be allowed for prior to undertaking field works to inform the required scope.

The Contractor is to allow for compliance with controls outlined in the Interim Environmental Management Plan.

Traffic Management Plan

A Traffic Management Plan (TMP) has been developed as part of the ongoing requirements outlined in the IEMP. The proponent is to allow for controls outlined below

• Exclusion zone signage is to be installed with the following details:

o Authorised Personnel Only

o Contaminated Soil – Dust Controls Required

o Speed limit: 10km/h

o Contact ARTC Area Manager

The signs are to be located at all 3 site entrances, and at the boundaries of Areas A, B and E. 10 signs in total are required, as outlined in Figure 2.

Signs are to be retroreflective aluminium with minimum dimensions of 600 x 900mm. and attached to a 2.4m long x 60mm OD galvanised steel pole with cap. Sign is to be fixed to pole with brackets or pre-drilled holes on pole.

The pole is to be installed 400mm deep with concrete footings, or utilising arrow socket in ground signpost mounts. Any excavated material is to be stockpiled, stabilised, and taken off site with the drainage sediment.

Installation of signage through excavation will likely trigger lead risk work requirements when disturbing soils – appropriate controls, including appropriate PPE and decontamination measures, are to be outlined in a job specific SWMS and implemented on site.

• The proponent is to propose a method(s) of dust control (e.g., polymer sealant suitable for the intended purpose and minimal maintenance requirements) for access roads, parking areas and access to signal locations (Area 3 outlined in table 1 below). Multiple options outlining cost comparisons and effectiveness are encouraged.

• Wheel inspection bays are to be installed between areas outlined in Figure 4 of the TMP. Requirements for wheel inspection bays are outlined in Table 2 of the TMP. The proponent is to propose a suitable methodology for construction of wheel inspection bays.

Erosion and Sediment Control

An Erosion and Sediment Control Plan (ESCP) has been developed as part of the ongoing requirements outlined in the IEMP. Installation of these controls will likely trigger lead risk work requirements when disturbing soils – as such appropriate controls are to be outlined in a job specific SWMS and implemented on site along with Lead Risk work requirements. The proponent is to allow for all ERSED controls outlined below. See Table 2 of the ESCP and Appendix A for further information:

• Check dams are to be installed every 20m along the surface drainage line through Area A, Former Morans Shed site, and Area B.

• Rip Rap rock to be installed within 2 x scoured areas on the western embankment (see photo 2 Appendix B ESCP, both of similar size).

• Installation of sediment controls around drainage inlets x 5.

• Installation of sediment controls around drainage sumps x 4.

• Installation of sediment traps at drainage outlets x 4 on council land

• Surface stabilisation, as per table 1. Figures can be found in Appendix A.

• Rate/m2 to be provided for hydromulching – including minimum area/charge for 1 day on site.

Ongoing Inspections

As per the approved IEMP, ongoing inspections of the implemented controls are to be undertaken monthly for 12 months. These inspections are to also include the following:

- Removal of sediment build up within the installed sediment controls and stockpiled at the designated location on site. The stockpile is to be stabilised with each maintenance visit.

- The above stockpile is to be disposed of at the end of the 12-month period. The proponent is to allow for completion of a waste classification and disposal off site. The proponent is to assume the material will be hazardous and totalling 12 tonnes of material to be taken off site with one rigid tipper. This includes material excavated for signage installation. A provisional rate is to be provided for any overs or unders to this amount.

- Maintenance of controls installed (e.g., repair of sediment fencing, replacement of damaged geotextile, Replacement of rip rap rock)

- Re-application of sealant at intervals outlined in the proposed product specification

- Hand seeding of any hydromulched areas not showing any signs of growth, if applicable.

Identification of areas requiring revegetating on the western embankment are to be identified during the initial works, and completed during the next inspection, if required.

- Completion of the inspection form for each visit

- Rail protection officer

- Provisional price for one off inspection (E.g., after heavy rainfall and prolonged strong winds)

- Maintenance of wheel inspection bays (E.g., addition of water to tanks, removal of sediment)

- Monthly inspection reports

Asbestos Removal

As per GHD DSI report, asbestos has been detected in soils at location “ACM11”. ARTC has subsequently undertaken waste classification and delineation of the area The proponent is to allow for the following:

• Excavation and removal of asbestos impacted soil to a licenced waste facility, and replacement with clean fill. Allow for the removal of 3m3 of GSW-A soil, and replacement with non-spec road base material, to be track rolled and crowned to shed water. Road base material shall comprise of non-recycled quarried materials, meeting the requirements of NSW EPA: The Excavated natural material order 2014.

• Clearance of the area by a qualified Occupational Hygienist/LAA and associated clearance reporting

• Validation sampling prior to backfill to confirm asbestos has been removed from soils

Junee Roundhouse

The Proponent is to implement all the controls outlined in both the provided ESCP and TMP and undertake ongoing inspections every second month, including minor maintenance for a period of 12 months after the initial site works are complete – I.e., 6 rounds of inspections and reporting after initial field works are complete

All spoil produced during site works are to be stockpiled at the designated temporary stockpile location and stabilised with polymer sealant, and removed from site after the 12 month maintenance regime is complete. The proponent is to include waste classification testing and disposal at a licenced facility.

Traffic Management Plan

A Traffic Management Plan (TMP) has been developed as part of the ongoing requirements outlined in the IEMP. Installation of these controls will likely trigger lead risk work requirements when disturbing soils – as such appropriate controls are to be outlined in a job specific SWMS and implemented on site along with Lead Risk work requirements. The proponent is to allow for controls outlined below (further detail can be found in Table 2 of the TMP):

• Speed signage to be erected. A total of 5 x speed signs are required as shown below in red

Signs are to be retroreflective aluminium with minimum dimensions of 600 x 900mm. and attached to a 1.8m long x 60mm OD galvanised steel pole with cap. Sign is to be fixed to pole with brackets or predrilled holes on pole. The pole is to be installed 400mm deep with concrete footings. Excavated material is to be stockpiled, stabilised.

• Exclusion zone signage and fencing is to be erected around the perimeter of ACM and lead impacted areas. Signage is to include the following information:

o Authorised Personnel Only

o Contaminated Soil – Dust Controls Required

o ASBESTOS

Exclusion zone fencing should consist of Star Pickets with rope red flagging (or similar) that is resistant to weather, plastic Caution tapes are not acceptable. Signs to be installed onto star pickets.

A total of 550m of fencing, and 7 sets of signs are to be allowed for

Erosion and Sediment Control

An Erosion and Sediment Control Plan (ESCP) has been developed as part of the ongoing requirements outlined in the IEMP. Installation of these controls will likely trigger lead risk work requirements when disturbing soils – as such appropriate controls are to be outlined in a job specific SWMS and implemented on site along with Lead Risk work requirements. The proponent is to allow for all controls outlined below. See Table 2 and Figure 3 of the ESCP for further information:

The proponent is to allow for:

• Lead impacted area

o Application of a polymer-based sealant such as Dustex. The proponent is to nominate a preferred product for application.

o The Sealant should be reapplied as specified by the manufacturer.

o As a secondary containment measure the lead impacted area to the west of the rail line should have sediment fencing erected, noting that sediment fencing is not achievable across the rail line. Trenching to install sediment fencing should be avoided so as not to disturb the impacted materials

• Sediment controls

o Installation of sediment controls at drainage inlets including installation of sediment fencing around the surface water pits.

o Removal of sediment and grit from the drainage outlets as required based on the inspections.

o Sediment is to be managed in accordance with the IEMP (Cavvanba 2022), stockpiled on site, stabilised at each visit, and removed at the end of 12 months after undertaking waste classification on all the removed material. The stockpile is to be located at the designated temporary stockpile location outlined in Figure 2b of the ESCP

o Care should be given with the design of sediment capture to ensure it doesn't result in 'damming' of the drainage inlets which will result in flooding.

A total of 5 culvert and 6 pits require run off controls, Culvert should be protected with coir logs, ballast check dams or equivalent, Pits should be protected with Sediment fencing, a total of 50m of sediment fencing is required to protect the pits.

• Stockpile management – runoff protection to be installed around the temporary stockpile location, that still allows for addition of new material. A total of 150m of sediment fencing is to be allowed for (3 x 50m fences around stockpiles)

Ongoing Inspections and Maintenance

The proponent is to allow for the following:

• Removal of sediment build up within the installed sediment controls and stockpiled at the designated location on site. The stockpile is to be stabilised with each maintenance visit.

• The above stockpile is to be disposed of at the end of the 12-month period. The proponent is to allow for completion of a waste classification and disposal off site. The proponent is to assume the material will be hazardous and totalling 12 tonnes of material to be taken off site with one rigid tipper. This includes material excavated for signage installation. A provisional rate is to be provided for any overs or unders to this amount.

• Maintenance of controls installed (e.g., repair of sediment fencing, replacement of damaged geotextile, Replacement of rip rap rock)

• Re-application of sealant at intervals outlined in the proposed product specification up to a period of 12 months from completion of initial field works

• Site inspection every 2 months

• Completion of the inspection form for each visit

• Rail protection officer (if working in the vicinity of the ARTC main line)

• Provisional price for one off inspection (E.g., after heavy rainfall and / or >100km/h and prolonged strong winds)

• Minor maintenance of installed controls – including re-installation of damaged erosion and sediment controls, adjusting installed signage, re-application of polymer sealant at intervals specified by the manufacturer, partial reapplication of sealant where identified during inspections (to be done at the following inspection)
