As a byproduct of our operations, we generate waste. These wastes include materials common to many businesses such as paper, aerosol cans, batteries, oils, paints and construction debris. Operation of the Columbia Generating Station also results in the generation of hazardous and radioactive waste streams subject to additional regulation and special handling requirements. These wastes are carefully managed in compliance with stringent State of Washington Department of Ecology regulations.
In 2012, Columbia Generating Station reduced its generator status for hazardous and mixed waste. Previously, the station was a large quantity generator; and now, a medium quantity generator. All other agency sites are small quantity generators.
We handle our waste in various ways, including non-hazardous and hazardous waste recycling, onsite treatment to reduce hazard or volume, accumulation for offsite disposal and operation of an inert waste landfill.
Energy Northwest seeks to minimize its generation of waste, especially hazardous and radioactive waste. We conduct pollution prevention opportunity assessments to identify and implement activities that reduce waste and we have a comprehensive recycling program. The major objectives of the Radioactive Waste Management Program are to limit, control, minimize, and measure the production of radioactive materials in solid waste, gaseous emissions and liquid discharges.
