GUIDELINES FOR THE PREPARATION OF
AN ENVIRONMENTAL IMPACT STATEMENT
FOR THE
WUSKWATIM TRANSMISSION PROJECT
APRIL 26 2002

1.     PURPOSE:

The purpose of this document is to identify for Manitoba Hydro, Nisichawayasihk Cree Nation and the public the information required by government agencies for consideration in an environmental impact statement for the Wuskwatim Transmission Project.

2.     INTRODUCTION

2.1   BACKGROUND

Manitoba Hydro and the Nisichawayasihk Cree Nation (NCN) are currently considering the development of the Wuskwatim Generation Project and associated infrastructure in the Nelson House Resource Management Area. Associated with the generation project, transmission facilities, both in and beyond the Nelson House Resource Management Area, will be required. The Wuskwatim Transmission Project facilities would provide for the transmission of power from the proposed Wuskwatim hydro-electric generating station to the existing Manitoba Hydro electrical transmission system. At the same time, the project would also provide transmission system improvements that are independent of the requirements of the proposed generating station.

The Wuskwatim Transmission Project proposes the development of new transmission lines and transformer/switching stations required in order to link the proposed electric generator to the existing transmission system. To accomplish this a transmission sub-station would be required at the Wuskwatim generating station site. This new sub-station would provide for voltage transformation and switching. At the sub-station, electricity would be received from the generators and transformed to a higher voltage that is necessary for transmission into the existing Manitoba Hydro system.

New 230 kV transmission lines would connect the sub-station at the Wuskwatim site to other stations on Manitoba Hydro’s transmission system. The points of connection to the existing system would be at Thompson, at a proposed new transformer/switching station south of the city to be called Birchtree Station, near Snow Lake, at the existing Herblet Lake Station on the north side of the community, and at The Pas, at the existing Rall’s Island Station. Manitoba Hydro advises that the proposed transmission line connections between Herblet Lake Station and Rall’s Island Station would be required in the future, independent of the development of the Wuskwatim Generation Project, to improve the existing regional electrical-transmission system. A schematic showing the location of the proposed project is provided as Schedule 1. to these guidelines.

Discussions between Manitoba Hydro and NCN regarding the future Wuskwatim Generation Project, as well as a potential development at the existing Notigi Control Structure, have been ongoing for several years. Article 8 of a 1996 Agreement signed by NCN, Manitoba Hydro, Manitoba, and Canada sets out a process for NCN and Manitoba Hydro to discuss potential future developments that could affect the Nelson House Resource Management Area and NCN members.

In 1997, NCN and Manitoba Hydro established a working group to facilitate ongoing consultation regarding the proposed developments. NCN and Manitoba Hydro are currently considering potential partnership arrangements for the development of the Wuskwatim Generation Project, should it proceed. An Agreement in Principle, which describes the partnership arrangement, was jointly prepared by NCN and Manitoba Hydro and was signed on September 25, 2001.

Among other things, Article 8 of the 1996 Agreement requires that Manitoba Hydro consult with NCN to identify issues of concern to the First Nation and to provide detailed information on the expected positive and negative effects of any project in the Nelson House Resource Management Area. To address these obligations, NCN and Manitoba Hydro jointly selected a study team in late 1999 to conduct the biophysical and socio-economic studies required and to provide sufficient information to conduct an environmental assessment of the proposed development. Following a series of scoping meetings held with NCN and Manitoba Hydro officials in early 2000, the study team designed and implemented a preliminary study plan, which is referred to as the Joint Study Program (NCN Manitoba Hydro: Joint Study Program, updated August 2001).

The Joint Study Program is concerned primarily with the Nelson House Resource Management Area and emphasizes potential concerns and issues associated with the generating station development. The related transmission facilities, although included under the Joint Study Program, would extend beyond the Nelson House Resource Management Area in order to provide connections to the existing Manitoba Hydro transmission system. The corresponding site selection and environmental assessment (SSEA) activities for the transmission facilities would be subject to the same general objectives and principles, but would extend geographically beyond the Resource Management Area and would include consultation with a number of potentially affected communities and interests other than NCN.

In October 2001, NCN and Manitoba Hydro, with the assistance of the study team, drafted a scoping document that provided useful background to the Project Administration Team* (PAT) in the preparation of these Guidelines for the Preparation of an Environmental Impact Statement for the Wuskwatim Transmission Project.

* The Canada – Manitoba Agreement on Environmental Assessment Cooperation provides that the Lead Party in a cooperative environmental assessment process will establish and chair a Project Administration Team with membership representing the federal responsible authority(ies) and Manitoba Conservation. The Project Administration Team would then be responsible for managing the cooperative environmental assessment.

2.2     ENVIRONMENTAL ASSESSMENT REQUIREMENTS AND PROCESS

The Wuskwatim Generation Project is a Class 2 development as defined in the Classes of Development Regulation under Manitoba’s The Environment Act and may require a screening or possibly be part of a comprehensive-study level environmental assessment under the Canadian Environmental Assessment Act.

Under the provisions of the Canada-Manitoba Agreement on Environmental Assessment Cooperation, the Parties have agreed that, where both governments have or may have an environmental assessment responsibility for a proposed project, a cooperative environmental assessment will be undertaken. Accordingly, these Guidelines for the Preparation of an Environmental Impact Statement for the Wuskwatim Transmission Project have been developed to address specific issues and identify necessary information that Manitoba and Canada require to be considered in the environmental assessment of the project.

The Project Administration Team has finalized the Guidelines after consideration of public comments, the Clean Environment Commission’s report on consultations regarding the Draft Guidelines and input received from a federal/provincial technical advisory committee (TAC).

The Manitoba Minister of Conservation has determined that there will be public hearings conducted by the Clean Environment Commission in accordance with subsection 6(5) of The Environment Act for the Wuskwatim projects. The hearings will be conducted in order for the Commission to review, based on the public input and the environmental impact statement, the issues raised in the environmental assessment process and provide advice and recommendations on those issues to the Minister in a report to be prepared subsequent to the hearings. The Clean Environment Commission hearings will incorporate consideration of the issues associated with both the Wuskwatim Generation Project and the Wuskwatim Transmission Project concurrently.

On January 29, 2002 the Government of Manitoba announced that it would establish a review process through the Public Utilities Board (PUB) that will provide for a public examination of the need for the project and alternatives to developing the proposed Manitoba Hydro projects. Based on this review process information, the PAT, in consultation with Manitoba Hydro and their study team, has developed a draft review schedule, which is provided as Schedule 2. to these Guidelines.
