Our goal is to operate Libby Dam to minimize negative impacts on the environment through pollution prevention and mitigation, and we are committed to continual improvement.  Our commitment is to comply with environmental legislation, rules, and regulations. We encourage environmental stewardship at every level throughout the organization..
