1 INTRODUCTION This ‘Environmental Plan Bridging Document - Summary – Parmelia Gas Pipeline System - RUSSELL ROAD INTERCONNECT PROJECT’ (RRI Project E-BD Summary) (RRI-PL-HS-0006) provides an overview of the environmental management requirements for the design and build of a connection between the Parmelia Gas Pipeline System (PGPS) and the ATCO Gas Australia (ATCO) South Metro reticulation system.

This is a summary document of the ‘Environmental Plan Bridging Document - Parmelia Gas Pipeline System - RUSSELL ROAD INTERCONNECT PROJECT’ (RRI Project E-BD) (RRI-PL-HS-0005) which bridges the environmental requirements and management techniques of the Operations Environment Plan Parmelia Gas Pipeline System (PAR-EMP-457; Rev 1.2; 26/06/2013) (PGPS OEMP) to the RRI Project.

1.1 Purpose and Scope

The purpose of the RRI Project E-BD Summary is to provide information to the general public regarding environmental considerations and management requirements. The scope of this RRI Project E-BD Summary is limited to the environmental management techniques applicable to the RRI Project which control environmental risks additional to normal Parmelia Gas Pipeline operations.

1.2 Objectives

The overall environmental objective of the RRI Project E-BD is as follows:

To describe the work to be undertaken to design and build a connection between the PGPS and the ATCO South Metro reticulation system;

To provide management techniques to minimise environmental impacts resulting from project activities;

To mitigate all identified environmental risks to ALARP;

To comply with all relevant legal and regulatory environmental requirements; and

To minimise disturbance to surrounding landholders.

2 PROJECT BACKGROUND The PGPS comprises the Parmelia Gas Pipeline mainline (PGP) and numerous lateral pipelines. The PGPS is owned and operated by APT Parmelia Pty Ltd (APA). The primary function of the PGPS is to transport gas from the Dampier to Bunbury Natural Gas Pipeline (DBNGP) and Mondarra Storage Facility (MSF) to customers located throughout in the south west of WA as far south as Pinjarra.

A growth opportunity exists for APA to supply natural gas to ATCO Gas Australia’s (ATCO) Metro South Reticulation Network with the PGP identified as ideally situated to provide transport of the gas. This project is called the RRI Project.

The RRI Project provides for the relocation of the existing filtration, metering and pressure reduction equipment located at the Kwinana Nickel Refinery (KNR) to the APA controlled Energy Commission Russell Road (ECR) compound.

The existing Russell Road Sales Tap (RST) (See ‘Russell Road Compound’ - Figure 1) has been chosen as the viable location for the new metering station. The RST is situated on the PGPS Mainline at KP356.1 which adjoins the ECR compound. The ECR is APA owned and currently unused. APA has an access agreement for the ECR with the Department of Lands (Infrastructure Corridors) who are the land owners.

Existing pipework is installed at the KNR site (Figure 2). Under the RRI Project scope, these materials will be removed and transported to the ECR site for the project.

As the RRI Project operations are being staged out of the PGPS Mainline, environmental aspects associated with the project fall within the scope of the accepted PGPS OEMP. The Operations Environment Plan Parmelia Gas Pipeline System (PAR-EMP-457; Rev 1.2; 26/06/2013) (PGPS OEMP) is the document being bridged to.

A Bridging Document is adequate to cover the proposed activities given that the project:

Pertains to new activities that are within the scope of the PGPS OEMP, for which the environment risks are covered; or

Will result in changed operational details from the scope of the PGPS OEMP, but do not result in any major additional or modified environment risks.

This is consistent with advice given in the DMP Guidelines for the Preparation and Submission of an Environment Plan (DMP, 2012).

Table 1 provides a summary of the scope of work associated with the RRI Project.

4 DESCRIPTION OF THE ENVIRONMENT A detailed description of the environment surrounding the PGPS is provided in the PGPS OEMP.

Specific to the ECR Site (Figure 1), the site contains no vegetation, soils generally consist of Spearwood Sands with varying amounts of organic material and gravel. Soils are very loose with no clay content. The site is relatively flat and is surrounded by bushland.

A desktop investigation of the ECR site and surrounding area found no known area of aboriginal or European heritage.

The majority of land surrounding the site has been developed for rural business practices or residences and consequently contains limited environmental value. Residual native bushland in proximity to the site has been heavily disturbed and also contains limited environmental value.

The ECR site lies on the northern slope of the Jandakot Mound system which extends from the Swan River in the north to the Serpentine River in the south. The RRI Project works will not exceed 1500mm below the existing ground surface. Interaction with groundwater systems is not anticipated and unlikely.

5 ENVIRONMENTAL RISK ASSESSMENT AND MANAGEMENT

The environmental risks associated with all activities conducted on the PGPS are addressed in the PGPS OEMP. A review of these risks under the scope of the RRI Project was undertaken in July 2015.

The objective was to ensure that all aspects, impacts and risks associated with the project were adequately assessed and control measures identified in the PGPS OEMP were adequate for the activities. Any new risks (or risks where the associated hazard was markedly different that of normal operations) are addressed in the RRI Project E-BD.

A total of 15 additional or changed risks were assessed as part of the ERA process and management measures and mitigation factors were identified to ensure risks were managed ALARP.

The APA standard risk methodology (WI-4.21.8 Risk Management (FIRM) Work Instruction) and matrix were used for the ERA. These have been previously developed by APA as per regulatory requirements and are consistent with AS/NZS ISO 31000:2009 (Risk Management – Principles and Guidelines) requirements.

The ERA was attended by the following APA project personnel:

APA Environmental Officer

APA Project Manager (RRI Project Manager)

APA Project Approvals Manager

APA Project Engineer

APA Team Leader (PGPS South)

A summary of the key environmental risks assessed during the workshop are below (Table 3). The corresponding control measures and mitigating factors for the RRI Project are included in Table 4 - 9.

Note: The below Tables are indicative of major hazards and controls and are not comprehensive of all commitments made by APA in the RRI Project E-BD or PGPS OEMP.
