3.3 Surface & Groundwater Water Management Plan (SGWMP)

Watercourse crossings, culverts and instream works will be conducted in accordance with the design drawings (S-PL-011-01; S-PL-011-02; S-PL-013-01; S-PL-013-02; S-PL-013-03) which have been submitted to NOW for approval.

The YWL Pipeline will require two test sections for the purposes of hydrostatic testing and will be tested in accordance with AS 2885.5. During testing the pipeline will be capped with test manifolds, filled with water and pressurised to the appropriate levels. It is estimated that approximately 7-8 mega litres of water used for hydrotesting which will be sourced from either existing Riverina Water Country Council supplies (standpipe) or alternative source (to be determined). Given that the water is high quality, it is anticipated that no chemicals such as oxygen scavengers or biocides will be added, therefore disposal to land does not pose a risk of soil or waterway contamination.

Hydrotest water will not be discharged directly to waters and will not impact upon landholders or their property values. The water will be discharged to land in such a way as to prevent runoff into any watercourse or drainage lines, flooding, or erosion (e.g. against a splash plate or other dispersive device in order to aerate, slow and disperse the flow). Discharge will be to an area greater than 100m from the nearest waterway.

Use of construction water (for dust suppression) will be dependent upon local environmental conditions (rainfall and soil type). Any construction water will be taken from the same sources as those provided above for hydrotesting.

No groundwater will be extracted or used during the project. According to the Environmental Assessment Report the pipeline is not traversing any areas where the groundwater table is anticipated to be intersected by construction works.

Objective No incidents of water contamination or uncontrolled runoff.


Contamination or pollution of water


Refuelling operations shall be conducted at least 50m away from waterways with spill kits on hand.

Spill response training provided.

4 Environmental Constraints

4.1 Sensitive Areas

The ROW corridor will be as per the APA alignment sheets and will be minimised wherever possible to minimise the impact on the environment.

Alignment sheets for the project are as follows:

YWL 80 – 0068 YWL 80 – 0069

YWL 80 – 0070 YWL 80 – 0071

YWL 80 – 0072 YWL 80 – 0073 YWL 80 – 0074

Localised sensitive areas (as identified by AECOM in the Environmental Assessment Report) include:

Remnant woodland at Bethungra Mountain and Billabung Creek

Hollow-bearing trees located within the Old Sydney Road to Ulandra Creek area and within the road reserve at Illabo metering station.

4.2 Potential Environmental Incidents

Potential environmental incidents shall be determined from Client work documentation and previous experience of similar pipeline projects. Work in new areas shall give consideration to identifying potential environmental incidents associated with work in the following activities:

known cultural heritage areas

activities involving hydrocarbons (for example, refuelling operations) and hazardous substances

open cut road and track crossings

open cut watercourse crossings

other facility crossings (e.g. gas, oil, water, power and telecommunication lines)

horizontal directional drilling and road boring

hydrotesting

steep slopes susceptible to erosion



the spread of weeds

community impacts such as increased traffic hazards.

APA/WDS shall notify the Director-General and any relevant Government authority of any incident with actual or potential significant off-site impacts on people of the biophysical environment as soon as practicable after the incident and will provide written details within 7 days from the incident occurring.

4.3 Special Construction Considerations

Suitable and approved construction procedures shall be prepared in consultation with the relevant Local Authority prior to any of the following activities taking place:

Open cut unsealed road and track crossings

Unsealed roads will be excavated by excavator/trencher and will be compacted and restored to a condition similar to the original condition to the satisfaction of the local authority. Road crossings will be completed in the shortest possible time to avoid trenches being left open unnecessarily.

Thrust boring sealed road

The pipeline will be constructed across sealed roads by thrust boring method, unless otherwise approved by the relevant authority. Launch and receive holes will be constructed a sufficient distance either side of the road to avoid damage to the road surface and a boring machine installed. The machine will bore under the carriageway at approximately 1.2 metres cover and the new pipeline inserted. After the pipeline has been ‗tied-in‘ with the main line, both holes will be backfilled and restored to original condition. The coating for the pipeline being inserted is upgraded with a rock shield or concrete jacket to ensure that no damage can occur to the original coating.

Thrust boring railway

The pipeline will be constructed across the railway by thrust boring method. Launch and receive holes will be constructed a sufficient distance on either side of the railway and a boring machine installed. The machine will bore under the railway at approximately 2 metres cover and the new pipeline inserted. After the pipeline has been ‗tied-in‘ with the main line, both holes will be backfilled and restored to original condition. The coating for the pipeline being inserted is upgraded with a rock shield or concrete jacket to ensure that no damage can occur to the original coating.

Open cut watercourse crossings

Work of this nature will be to a design agreed with the authority. Dry crossings are anticipated for all crossings and will be trenched through similar to the easement work. In the event that rain causes these creeks to flow during construction the water will be carefully diverted around the work area whilst excavation is carried out and restored upon completion.

Horizontal directional drilling river crossing

HDD procedure is a specialised task carried out by industry specialists and involves the use of pressurised ‗mud‘ to maintain the bore whilst drilling process continues. The drilling rig is positioned to one side of the crossing well away from the banks and the drill is carefully guided under the river bed to a specific profile to ensure that the pipeline can be easily inserted and will remain clear of the river bed to avoid any possibility of future damage. The drill reappears on the far side of the river and a



reaming head is pulled back through opening the bore to the appropriate diameter. The powercrete coated pipeline is pulled into the bore and connected to the mainline and the displaced ‗mud‘ is collected and disposed. Both sides of the river will be restored to the original conditions.

A specific procedure for the HDD process will be developed to suit the prevailing conditions by a specialist contractor in consultation with the local authorities. The procedure will incorporate all necessary environmental procedures.

Hydrotesting

Hydrotesting will be carried out in two sections reusing the water from the first. The process involves filling the pipeline and removing trapped air prior to pressuring. The water will be sourced from a local water distributor or an alternative source (to be determined) and upon completion of works will be released using specialist nozzles designed to reduce the likelihood of erosion. It is anticipated that no corrosion inhibitors or biocides will be added to the water.

Environmental management issues associated with these activities shall include air quality, water management, erosion, dust, flora and fauna and vehicle traffic and be included in these procedures and be addressed in the Environmental Management Sub-Plans in section 3.

4.4 Cultural Heritage

Cultural heritage issues will be managed by the Client.
