CITY OF PRINCE GEORGE SNOW DISPOSAL STUDY AT THE LANSDOWNE ROAD WASTEWATER TREATMENT CENTRE 1.0 INTRODUCTION The City of Prince George currently transports snow from street clearing operations in the downtown area to land disposal sites at Hudson Bay Slough and Carrie Jane Gray Park. A third land disposal site is located at River Road, however, considering the Department of Fisheries concern for snow disposal and resulting habitat damage, the City has not used this site for the last two winter seasons. The lease on the River Road site expires in 1997 and it will not be renewed. The dump sites discharge snow melt runoff to the foreshore of the Fraser River. Environmental and land use concerns associated with the dump sites have led the City to explore other disposal methods. In 1993, the City and the Fraser Pollution Abatement Office (FPAO) of Environment Canada commissioned a study to assess snow disposal options. A City Public Works task group has since identified a further disposal option at the Lansdowne Road Wastewater Treatment Centre (WWTC). Preliminary testing by the City at the WWTC indicated that loading the snow into the chlorine contact tank immediately prior to discharge of the treated effluent had sufficient merit to warrant further study. The City issued a Request for Proposals (RFP) on December 14, 1995, for a study to evaluate in detail the option of snow disposal at the WWTC. A copy of the RFP is included in Appendix 1. This report contains the results of the study. Dayton & Knight Ltd. Page 1-1
