Updates

Thank you for your interest, cooperation and patience during energetic felling activities of the wind turbines at the Casper Wind Farm Decommissioning site.

We are pleased to share that energetic felling, the controlled use of explosives to safely bring down structures, has been completed. Disassembly of the remaining wind turbines using a crane and transportation activities will continue at the site, so community members may continue to see equipment and vehicle activity in the area.

We remain committed to conducting this work safely and responsibly while minimizing disruptions to neighboring businesses and the surrounding community.

If you have questions or concerns, please feel free to contact us via our Community Hotline at 855-285-9595.

Casper Wind Farm Decommissioning Update

As part of ongoing decommissioning activities at the Casper Wind Farm in Natrona County, Chevron and its contractor plan to use energetic felling techniques, including controlled explosives, to remove select wind turbine towers beginning approximately 72 hours from this notice.

This notice is being issued on Friday, August 21 to provide stakeholders with adequate review time. The 72-hour notification period will begin on the next business day, Monday, August 24, at 8:00 a.m.

The use of energetic felling is a planned part of the wind turbine removal process.

What neighbors may notice:

• A brief, loud noise at the time of tower felling.
• Temporary vibration that may be felt in areas near the project site.
• Increased activity from construction equipment, cranes, trucks, and work crews supporting decommissioning activities.
• Traffic associated with project work along local routes, including Stonewood Street and Sunburst Drive.

The activity is being carried out under established safety procedures and work controls. Chevron and its contractors have implemented safety and environmental measures that include trained on-site personnel, traffic controls where warranted, dust management practices, fire prevention protocols, and other site-specific safeguards.

We appreciate the community’s patience as this work progresses. Residents with questions or concerns may contact the project team through the community hotline at 855-285-9595 or visit the project website at casperwindfarmdecommissioning.com.

Project Timing

Decommissioning activities are planned to begin this summer. Initial work by a third-party contractor is expected to include removal of turbines and associated components over a period of several months. Additional site work may continue following initial removal activities, depending on field conditions, weather, and other factors.

What the Community May Notice

Residents in the area may observe:

• Increased truck traffic along local routes, including Stonewood Street and Sunburst Drive
• Water trucks supporting dust management and road maintenance
• Movement of equipment, materials, and work crews to and from the site
• Crane unstacking and energetic felling including the use of mobile cranes and equipment for turbine lowering and removal. Periods of controlled blasting may increase noise and vibration associated with this work. All work is conducted under strict safety standards.
• Work occurring generally during daytime hours (approximately 7:00 a.m. to 7:00 p.m.), with adjustments communicated as appropriate

Safety Measures

Chevron and its contractors are implementing standard safety and environmental controls, including:

• On-site safety personnel
• Dust control measures, including use of water trucks
• Fire prevention and monitoring protocols
• Hazardous material handling procedures
• Work may require preparation and maintenance of local roads, including Sunburst Drive and Stonewood Street
