Deep Panuke is owned by Encana Corporation (Encana). Encana hereby applies to the National Energy Board (NEB) for leave to abandon the Deep Panuke pipeline and associated onshore facilities pursuant to Section 74(1)(d) of the National Energy Board Act (NEB Act) and Section 50 of the NEB Onshore Pipeline Regulations (OPR). See Figures A-1 and A-2 in the Deep Panuke pipeline Abandonment Plan (included as Attachment 2 to this application) for maps of the Deep Panuke Development location and of the Deep Panuke onshore pipeline and facilities. Applicant 1. Encana is a “company” as that term is defined in the NEB Act and is the applicant for this Leave to Abandon Application. 2. The Deep Panuke Development is a natural gas development consisting of an offshore platform (production field centre or PFC), subsea wells, infield flowlines/umbilicals, and a gas export pipeline and associated onshore facilities. The NEB regulates the pipeline, which consists of a 560 mm diameter sweet natural gas subsea pipeline, 175 km in length (172 km offshore and 3 km onshore), and the associated onshore facilities. The pipeline begins at the top of the PFC riser and extends to, and includes, the onshore facilities in Goldboro, Nova Scotia (where it ties into the Maritimes & Northeast Pipeline (M&NP) facilities). 3. Encana is the Operator of Record for Deep Panuke. Encana owns the Deep Panuke facilities, with the exception of the PFC, which is owned by Single Buoy Moorings Inc. (SBM). Encana applies corporate policies in Deep Panuke operations; SBM, by terms of its contract with Encana, applies Encana’s corporate policies in PFC operations. Facilities History 4. Encana submitted an application for a Certificate of Public Convenience and Necessity to the NEB for the Deep Panuke pipeline and associated onshore facilities (NEB Pipeline Application) in 2006. Encana also submitted a Development Plan Application for Deep Panuke to the Canada-Nova Scotia Offshore Petroleum Board (CNSOPB) in 2006. These applications provided a detailed description of the construction and operation phases of Deep Panuke. Decommissioning and abandonment activities were also described in the applications. 5. Deep Panuke was subject to the Canadian Environmental Assessment Act (CEAA) and submitted an Environmental Assessment Report in 2006 in support of the NEB, CNSOPB and CEAA processes. Decommissioning and abandonment activities were assessed in the approved 2006- 2007 Deep Panuke environmental assessment conducted under CEAA and in support of the NEB and CNSOPB approval processes. 6. The NEB issued a Certificate of Public Convenience and Necessity, GC-111, to Encana in respect of the Deep Panuke pipeline and associated onshore facilities pursuant to section 52 of the NEB Act in 2007. The NEB also issued Order GPLO-E112-007-2013 granting leave to open the Deep Panuke pipeline in 2013. 7. In 2017, Encana was reaching a stage of declining production and began preparing for decommissioning and abandonment activities. Deep Panuke Application for NEB Leave to Abandon • June 2018 4 8. On February 28, 2018, Encana met with NEB staff for a pre-application meeting to provide a status update and outline Encana’s plan to file an application to abandon the Deep Panuke pipeline and associated onshore facilities. 9. Encana submitted a Pre-Application Project Description to the NEB on March 19, 2018, providing preliminary information about Deep Panuke decommissioning and abandonment activities. 10. Encana permanently ceased production from Deep Panuke on May 7, 2018. 11. The Deep Panuke facilities continue to be safely maintained and monitored using the asset integrity plans and the maintenance management system for Deep Panuke. 12. No economically viable alternatives to abandonment have been identified. Scope of the Abandonment Activity 13. Section 74(1)(d) of the NEB Act and Section 50 of the OPR require that a company proposing to abandon the operation of a pipeline must submit an abandonment application to the NEB. Encana seeks NEB approval to abandon a 560 mm diameter pipeline, 175 km in length from the Deep Panuke PFC offshore to where it ties into M&NP facilities in Goldboro, Nova Scotia. It also includes the decommissioning and abandonment of associated onshore facilities, which include a beach valve station and a gas export pipeline terminus (GEPT) site. 14. Refer to Attachment 1 for the completed Guide B (Abandonment) and Guide K (Decommissioning) Filing Manual Checklists detailing concordance of this application. 15. Refer to the Deep Panuke Pipeline Abandonment Plan (Attachment 2) for detailed decommissioning and abandonment activities and methodology rationale. 16. For detailed abandonment schematics, refer to Attachment 3. 17. For the environmental and socio-economic assessment for Deep Panuke decommissioning and abandonment (ESA), refer to Attachment 4. 18.
