Reasons for a Federal Assessment

On October 5, 2009, it was determined that an environmental assessment was required in relation to the project because Western Economic Diversification Canada considered providing financial assistance to the proponent.

Project Description (as posted in the Notice of Commencement)

This project will upgrade and update the existing wastewater treatment plant to provide tertiary treatment and nutrient management to protect the Thompson River and to meet all provincial and federal regulatory requirements. The project will result in reduced greenhouse gas emissions through methane capture, reduced water use by re-using reclaimed wastewater effluent and composted sludge, and supports the watershed approach that Kamloops is taking to concurrently manage water, wastewater, and stormwater. The original BCF application included a cost estimate of $35.5 million for the major wastewater treatment upgrade initiated by the City of Kamloops. This request was modified to focus on the core components of the project, estimated at $21.3 million and reflecting a provincial-federal funding commitment of $14.2 million. The City will complete the non-core work to complete the total project. This project consists the following core elements:  Site preloading and dewatering;  New septage handling facilities and equipment;  Construction of core facilities to provide tertiary treatment with nutrient removal, including: - conversion of lagoons to a modified, activated-sludge process; - installation of equipment for aeration and UV disinfection; - Construction of periphery works, including: - outfall structure reconfiguration; berm improvements for 200-year flood protection, - standby power, cover for cells 1A/1B, plant water supply and entrance improvements; and - Design and construction engineering services. The project benefits the 85,000 people served by the treatment plant plus residents of surrounding rural areas who rely on the plant for their septage disposal. The upgrades to the tertiary treatment plant will increase effluent quality for the protection of the Thompson River for fish and recreation and for those who collect their drinking water downstream of the plant.

Final Decision

A decision was taken on November 18, 2009 and was that the authority may exercise any power or perform any duty or function with respect to the project because, after taking into consideration the screening report and taking into account the implementation of appropriate mitigation measures, the authority is of the opinion that the project is not likely to cause significant adverse environmental effects.
