Code of Practice in the Coal Seam Gas Industry

The APGA Code of Practice for Upstream Polyethylene Gathering Networks in the Coal Seam Gas Industry (the Code) has been developed to provide guidance to all industry participants. It encapsulates the best techniques and methods currently available and is cross-referenced to relevant Australian and international standards wherever possible. The latest edition is  Version 4 Supplementary.

The APGA Code of Practice for Upstream PE Gathering Lines in the CSG Industry was developed to meet the evolving needs of the industry in Australia by representative members of all sections of the industry and through the support of the Plastics Industry Pipe Association of Australia Ltd (PIPA).

Initially made available only to APGA and PIPA members, the APGA Board determined in 2017 that the Code should be available to all those involved in the coal seam gas industry so that the best technical guidance is always accessible.

Version 4 Supplementary of the APGA Code of Practice for Upstream Polyethylene Gathering Networks in the Coal Seam Gas Industry was published in August 2017. Version 4 Supplementary will have an accompanying series of Companion Papers which will be published below as they become available. Feedback will be sought from the industry on the Companion Papers. To provide feedback, use the form.

The Code is referenced in Queensland legislation. At the time of publication, APIA PE CoP for Upstream PE Gathering Networks CSG Industry V3 and Supplementary 0515, was the version referred to in the legislation. Version 4 Supplementary is expected to be referenced in 2017.

Companion papers

A suite of companion papers is being developed to be used in conjunction with Version 4 Supplementary of the APGA Code of Practice for Upstream PE Gathering Networks – CSG Industry as a means to document technical information, procedures and guidelines for good industry practice in the coal seam gas (CSG) industry.

These documents form part of the suite of documents together with the Code and are intended to:

  • be used in the design, construction and operation of upstream PE gathering networks
  • provide an authoritative source of important principles and practical guidelines for use by responsible and competent persons or organisations.

These documents should be read in conjunction with the requirements of the Code to ensure sound principles and practices are followed. These documents do not supersede or take precedence over any of the requirements of the Code.

Feedback on the companion papers is encouraged and can be provided via this online form.

Companion papers will be added to this list as they become available.
