Environmental Impact Assessments

The environmental impact assessment is a planning tool, which takes into account all environmental impacts while focusing on the most significant items and considers the interests and expectation of all concerned parties to ease choices and decision making. Personnel’s expertise, knowledge of the various regulatory processes, achievements and experience in these disciplines, as well as their cooperation spirit with the various specialists enable UDA to prepare, coordinate and edit environmental impact studies that meet regulatory authority requirements.


  • Field agriculture, forestry, fauna and flora inventories;
  • Options study and selection of lesser impact location, on route;
  • Impact assessment of the various components;
  • Development of mitigation measures;
  • Coordination, writing and edition;
  • Collaboration during stakeholders consultation and information sessions;
  • Expert testimony during public hearings;
  • Request for municipal regulation compliance certificate;
  • Request for certificate of authorization (C.A.) to the MDDELCC;
  • Permit requests;
  • Environmental inspection;
  • Post construction monitoring;
  • Research and monitoring of environmental compensation projects.

Typical projects : Environmental Impact Assessments


Storage Tanks Farm in Montreal-East

Canterm Canadian Terminals Inc. (Canterm) project was aiming at accommodating the ever increasing demand for storage of petroleum and related products. The project consisted in the construction of 11 additional storage tanks (for a total capacity of approximately 1,440,000 barrels) on existing Canterm operating site in Montreal-East. This project was submitted to the environmental impact assessment and examination procedure. UDA ensured coordination, preparation and edition of the environmental impact assessment, in association with its client and several specialists. UDA’s involvement was also required during the information and consultation process and the public hearings held by the Bureau d'audiences publiques sur l'environnement (BAPE).

St. Lawrence Pipeline

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, MRCs, etc.) required for the construction of the 240 km pipeline connecting Ultramar’s Levis refinery to its storage installation in Montreal-East. The characteristics of the project required the preparation of an environmental impact assessment (EIA) satisfying provincial and federal guidelines. The EIA preparation/coordination/edition mandate was awarded to UDA including field inventories in order to collect the data required for the identification of specific mitigation measures. The process started in February 2005 with project notice deposit, followed by the EIA transmittal in May 2006, and BAPE public hearings mandates in 2006-2007. The first Quebec Government decree was issued in October 2009 and the construction works started in June 2011.

Implementation of a Technical Landfill Cell

The Depot Rive-Nord project consisted in expanding company’s existing landfill infrastructures located in the Berthierville area. The project was subject to the environmental impact assessment and examination process under the Act on the implementation and expansion of certain landfill sites. In the outline of the environmental impact assessment, UDA was mandated to carry out the following activities:

  • Characterization of the area and its surrounding targeted for the implementation of the technical landfill site and excess excavated material parks;
  • Orientation and design of parks for the storage of excess excavated material leading at the same time to the restoration of two degraded sites (project related to the expansion project);
  • Landscape integration study associated with the new and existing landfill infrastructures, the anticipated developments of the degraded sites as well as the design of visual screens;
  • Specialized study of opportunist animal species;
  • Characterization of the wetlands located in the area of expected developments.

UDA was also responsible for the final revision of the impact assessment in association with the client and subconsultants. Finally, UDA is still involved in this project for environmental monitoring including those associated with wetlands and noise level.
