Project 

St. Lawrence Pipeline (Ultramar)

In 2004, from the inception of the Ultramar project, UDA participated actively in obtaining permits/authorizations from regulatory authorities (MDDEP, BAPE, CPTAQ, MPO, TC, Municipalities, MRC, etc.), which are required for the construction of the 240 km pipeline between the refinery in Levis and the storage facilities in Montreal-East.

UDA was also involved in the information and consultation process with the various stakeholders in every step of this major project. In fact, the Ultramar pipeline crosses the territories of 10 Regional County Municipalities (MRC), 32 municipalities, 5 federations of the Union des producteurs agricoles (UPA), as well as the lands of some 680 owners.

Various mitigation measures were implemented in order to minimise anticipated impacts on the environment. The most important were associated with the habitat of the western chorus frog, a regulated area for the golden nematode, tree clearing restrictions including those associated with the territory of the municipalities having less than 30% of forest cover, the crossings of some 250 watercourses, the wetlands, the subsurface drainage systems and the transplantation of some species with a particular status.

UDA also carries out the environmental inspection during construction works (2011-2012) and rehabilitation of the area used (authorized) during pipeline installation.

Extension towards the Portland Natural Gas Transmission System (PNGTS) Network (TQM Pipeline)

In 1998-1999, Trans Quebec and Maritimes Pipeline (TQM Pipeline), which shareholders are TransCanada PipeLines (50%) and Gaz Metro (50%), constructed a 217 km pipeline between Lachenaie and East Hereford. For this project, UDA carried out the studies (including the environmental impact assessment) required for obtaining the authorizations/permits. UDA’s personnel participated actively in the information/consultation program dedicated to the various stakeholders involved, including those of the territories (9 MRC and more than 40 municipalities) directly concerned by the project. Not only did UDA participate to the provincial regulatory procedure (environmental impact assessment, BAPE hearings, etc.) but also to the federal regulatory process, involving several regulatory authorities, including the National Energy Board (NEB) and various public hearing phases of this organization.

It is worth mentioning that this project required crossing of a natural park and more than 200 watercourses (including des Prairies, Richelieu, Yamaska, Magog, Coaticook and St. Lawrence rivers), transplanting some 33,000 plants of a species with a particular status, as well as constructing refuelling stations for the machinery. The latest measure was implemented to reduce the potential impact of an accidental spill in an area considered sensitive.

Also, during the construction and final clean-up and reclamation of the work zone, UDA provided an on-site environmental inspection team (up to 14 inspectors), comprising various specialities. Following the final rehabilitation, UDA conducted several monitoring activities for up to five years in some cases, to verify if the mitigation measures implemented during the construction work had produced the expected results.

Rabaska

In 2004, Rabaska (company regrouping Gaz Metro, Gaz de France and Enbridge) initiated its project for the construction of a LNG terminal on the south shore of the St. Lawrence River, on the territory of the City of Lévis. The objective was to construct the required facilities to receive liquefied natural gas (LNG) by tanker. The project included a maritime pier, two LNG storage tanks, regasification equipment, and a 42-km pipeline to tie-in to the existing transportation system. For the later component, UDA was mandated to prepare all the required documents for obtaining permits and authorizations. UDA also participated in the consultation and information process implemented by Rabaska, including meetings with some 120 landowners concerned by the project. Finally, UDA was involved in the joined federal-provincial public hearings process.

Gazoduc Bécancour (Gaz Métro)

In 2003, Gaz Metro initiated the required steps for the construction of a 15-km pipeline between the North (Trois-Rivières) and South (Bécancour) shores of the St. Lawrence River. The main stake of this project consisted in crossing the St. Lawrence River on a distance of 2.3 km. UDA was involved in this project from its inception and during the execution (2004-2005) since the firm was awarded an environmental inspection mandate for the construction and during final clean-up and reclamation of the work zone. It is worth mentioning that UDA prepared the required documents for obtaining the permits and authorizations and was also involved in the federal, provincial, regional and municipal regulatory processes. In fact, although the crossing of the St. Lawrence River was achieved using the directional drilling method, the open-cut method was approved by regulatory authorities as an alternate pipeline installation scenario, which included an important management planning program for the ships circulating in the marine waterway.

EasternAccess (TQM Pipeline)

UDA started its involvement in the project directed by Trans Quebec and Maritimes Pipeline (TQM Pipeline) known as the EasternAccess – TQM Pipeline in 2007. This project consisted in constructing a 235 km pipeline, and associated facilities, connecting the projected LNG terminal in Cacouna (Energy Cacouna Project) to the existing TQM Pipeline located in the St. Nicolas sector in Lévis. For this project, subject to the obtaining of permits/authorizations from municipal, regional, provincial and federal authorities, including the National Energy Board, UDA prepared the documents required to this effect. In addition to its participation to the consultation/information process led by TQM Pipeline, UDA was mandated to meet individually the 1,000 landowners concerned by the preferred route in order to obtain various authorizations from them. UDA was also responsible to conclude the option and right-of-way agreement with each of these landowners.

Extension of the Natural Gas Transportation System to the South Shore of Quebec (TQM Pipeline)

TQM Pipeline extended its natural gas transportation system to the South shore of Quebec in 1994. This project required crossing the St. Lawrence River between Saint-Augustin-de-Desmaures (North shore) and Saint-Nicolas (South shore). The project, covering a total distance of approximately 13 km, involved the construction of a 3.3 km tunnel (approximately 3 m diameter) under the St. Lawrence River, which represented a major challenge. UDA was involved in requests for permits and authorizations, including the National Energy Board process since TQM Pipeline facilities are regulated by this organization.

Les Cèdres Pipeline (TransCanada PipeLines Limited)

As part of its project to increase the capacity of its natural gas transportation system in Quebec, TransCanada PipeLines Limited (TransCanada) built, in 2006, a third pipeline adjacent to the existing ones (the first dating from the 1950’s). The new pipeline has a diameter of 914 mm (36 inches) and covers a distance of 21 km in the territory of Vaudreuil-Soulanges MRC. Since TransCanada is subject to the National Energy Board (NEB) regulation, UDA participated to the preparation of the required documents to obtain the authorization from this organization. UDA was then responsible to prepare the environmental impact assessment and all other documentation required for the decision process by the CPTAQ and issuance of the certificate of authorization by the MDDEP. UDA also carried the environmental inspection during the construction and final clean-up and reclamation of the work zone.

Natural Gas Underground Storage Installations in St. Flavien and Associated Projects (Intragaz)

Since 1997, Intragaz has been operating natural gas underground storage facilities in Saint-Flavien, on the site of an exhausted natural gas deposit that had been operated by SOQUIP between 1980 and 1994. The start-up of the Saint-Flavien facilities required in 1997 the construction of a 25 km pipeline by Gaz Metro, between the facilities of TQM Pipeline in Saint-Nicolas and Intragaz in Saint-Flavien. As part of this project, UDA participated in the identification of a route of lesser impact, the undertaking of various studies leading to the obtaining of the required certificates or authorizations from several governmental authorities, including the MDDEP and CPTAQ, as well as the environmental surveillance during the construction work and final clean-up and reclamation of the work zone. Between 2000 and 2004, UDA was involved in connecting the horizontal wells bored by Intragaz to increase the storage volume of the Saint-Flavien facilities. UDA also prepared the required documents to obtain the necessary authorizations from the CPTAQ and carried out, on an ad hoc basis, the agricultural surveillance during the construction work and final clean-up and reclamation of the work zone.

Portland-Montreal Pipeline System - Upgrade of the 457 mm Pipeline for Crude Oil Transportation (Montreal Pipe Lines Limited)

In 1999, Montreal Pipe Lines Limited converted its 457 mm (18 inches) pipeline to transport crude oil. This pipeline had been used for natural gas transportation between Brigham and South-Portland since 1987. UDA carried out several studies and prepared various documents to obtain the required authorizations, certificates or permits from NEB, DFO, MDDEP and CPTAQ. UDA was also involved in the information sessions as well as the environmental surveillance during various works carried out on the pipeline, including the replacement of a 3.9 km pipeline section across the Sutton Mountain, and the final clean-up and reclamation of the work zone.

Pipeline Maintenance in Senneville and Sainte-Anne-de-Bellevue (Gaz Métro)

In 2009, Gaz Metro conducted maintenance activities on a section of its distribution system, which is located in the municipalities of Senneville and Sainte-Anne-de-Bellevue. These works consisted in verifying the 508 mm (20 inches) pipeline coating on a distance of 4 km, as well as replacing the coating where required and some sections of the pipeline. For this project crossing an arboretum, UDA prepared the required documents to obtain the approvals from MDDEP and CPTAQ. UDA was also involved in the consultations/information process with concerned stakeholders and carried out the environmental inspection during construction activities and final clean-up and reclamation of the work zone.
