Great River Energy has an ongoing commitment to manage the environmental aspects of its operations in a way that minimizes its impact to the environment. This dedication is demonstrated by the inclusion of environmental sustainability in our mission statement, a commitment to renewable energy, various stewardship activities and maintenance of the International Organization for Standardization (ISO) 14001 registration of our generation and transmission facilities.
In 1999, Great River Energy established an environmental policy that is reviewed annually and continues to guide employee conduct. This environmental policy is an integral part of the Great River Energy culture.
Great River Energy has developed and implemented environmental management systems (EMS) that cover operations at our power generation facilities and our entire transmission division.
Great River Energy has several facilities that have achieved LEED (Leadership in Energy and Environmental Design) certification from the U.S. Green Building Council (USGBC). LEED is the nationally accepted rating system for buildings that demonstrate energy efficiency and sustainability.
Environmental resources are among the first things we begin researching when we are looking for specific places to build a new power line. Working with local leaders, governmental agencies such as the Department of Natural Resources, and other environmental organizations is always an important part of our process.
We work hard to balance environmental considerations, engineering standards and landowner input with our responsibility to provide our members with safe, reliable electric service. Although avoiding environmental impacts altogether is not always possible, we strive to minimize environmental impacts on every project by:
In addition to other management tools, Great River Energy proactively employs third-party auditors to conduct audits to assess its compliance and operational controls with the goal of continual environmental improvement. Great River Energy also is periodically inspected by regulatory agencies. The organization’s auditing program is a substantive review and check of the effectiveness of its environmental compliance program. Great River Energy uses audits to ensure continued compliance and the integrity of its programs. All major environmental compliance areas (i.e., air, water, waste, etc.) are audited on a revolving six-year schedule.
Great River Energy continuously strives to reduce the air emissions from its power plants. Our DryFiningTM system provides further significant reductions in Coal Creek Station and Spiritwood Station emissions.
Coal Creek Station began using DryFined coal in 2010, reducing emissions of sulfur dioxide (SO2) by more than 40 percent, nitrogen oxides (NOx) by more than 20 percent, and carbon dioxide (CO2) by 4 percent.
On June 10, 2014, United States Environmental Protection Agency issued a risk-based approval, pursuant to 40 CFR 761.61(c), for disposal of polychlorinated biphenyl (PCB) remediation waste to the Utility Solid Waste Activities Group (USWAG) member companies. Great River Energy is a USWAG member company, as listed in Appendix II of the approval. This approval allows for disposal of non-liquid PCB remediation waste generated at secure utility assets, with as-found PCB concentrations <50 parts per million (ppm), in non-TSCA approved landfill facilities, including municipal solid waste landfills, as described in Condition 9 of the approval. EPA believes the approved disposal method, provided all conditions of the approval are met, will not result in an unreasonable risk to health or the environment.
