Pollution Prevention

Energy Northwest maintains a pollution prevention program to reduce the use of hazardous materials and the generation of wastes. Our pollution prevention program addresses energy efficiency and conservation, water efficiency and conservation, waste minimization, spill prevention, and chemical management.

Key program activities include developing an environmental excellence plan for the environmental stewardship objectives and targets, increasing employee awareness and communication of pollution prevention activities, and providing technical assistance on new pollution prevention related initiatives.

In addition to integrating environmental protection measures into our operations, we are committed to developing cost-effective renewable energy.

Renewable energy projects include:
Diversion of Non-Hazardous Waste from Landfill

​In FY2017, Energy Northwest diverted approximately 220 tons of
non-hazardous waste from the landfill through recycling.  Graph displays percentage of total waste diverted (Dark Blue) from the landfill from

Columbia Hazardous Waste Generation

Through the Pollution Prevention (P2) Program, Energy Northwest continues to set aggressive targets to reduce all types of waste including hazardous and  mixed waste. The pollution prevention program prioritizes minimizing waste through job planning and substitution of products with more environmentally friendly chemicals.  Graph displays annual hazardous waste generation from Columbia Generating Station operations.  

Energy Use

Through the Pollution Prevention (P2) Program, Energy Northwest continues to set aggressive targets to reduce the amount of energy consumed at agency facilities. Graph displays annual energy use at Columbia Generating Station and Industrial Development Complex.  Since 2014, Energy Northwest has been upgrading facilities to increase energy efficiency through lighting upgrades, installing occupancy sensors, and replacing aging equipment.
