PARSC 014 –Recommended Long Term Monitoring Program for All Aspects of an Abandoned Pipeline FEATURED


On behalf of the Pipeline Abandonment Research Steering Committee (PARSC), PTAC wishes to retain the services of a research organization or consulting firm (the Contractor) to provide the services described in this document.


Pipeline abandonment refers to the permanent removal from service of a pipeline. Depending on a number of factors, sections of pipeline may be abandoned in place or removed.
Some risks may remain after a pipeline is abandoned. Long term monitoring is generally recommended to mitigate risk conditions. General guidance for the development of a long-term monitoring program is provided in Section 4 of the following document: Pipeline Abandonment – A Discussion Paper on Technical and Environmental Issues, available from the website of the National Energy Board . Furthermore, a recent example of a proposed long-term monitoring program is described in Appendix 7.9 of the Engineering Decommissioning Report for the Line 3 Replacement Program by Enbridge (See Section 7.5 On-Going Monitoring).

Project Objective

The objective of this project is to develop, for all aspects of an abandonment project, a recommended long-term monitoring program that is risk based and practical. The program should consider situations where the pipe is abandoned in place and where it is removed, with a focus on abandonment in place.

Project Scope

The purpose of the recommended program is to assist pipeline operators, regulators and land owners in the development, review and acceptance of a detailed long-term monitoring program in a specific abandonment project. As such, the recommended program will act as a first step and as a common starting point for specific detailed work by pipeline operators and stakeholders, and should cover all necessary aspects and address typical and most special situations that may be encountered.

The major components of the project are envisioned as follows:
1. Literature review to identify any prior work, program or practice developed or in place in other jurisdictions, such as the United States, Europe and Australia.

2. Building from past guidelines and recent examples, develop a structure for the major elements of a long-term monitoring program that would generally apply to all abandonment situations, including a discussion of conditions to be monitored, suggested monitoring methods, and suggested monitoring frequencies, based on pipeline characteristics, land use categories, special site conditions, and technical issues that may be present.

3. Summarize the above information in a recommended program document.

Please refer to the attachments section of this RFP notice for full descriptions of the RFP and RFP Outline.
