Environmental Considerations

TMT will follow a Comprehensive Management Plan to protect and conserve Maunakea’s cultural and natural resources during both on-going operations and construction to prevent any detrimental impacts. In addition, we will have cultural, archaeological, and construction monitors on-site at all times during construction.

Protecting Indigenous Species – An Invasive Species Control Program will educate employees about the status, condition, diversity and protection given to the natural resources on the mountain, including the Wekiu bug habitat.

Minimizing Energy Use – The project’s facilities will incorporate solar hot water systems, solar panels, energy-saving power and communication devices and will conduct an annual audit designed to further reduce energy use.

Protecting the Water Supply – Comprehensive research by expert, independent hydrologists confirms that TMT will have no adverse impact on the water resources and hydrology of Maunakea. The top of Maunakea is an “alpine desert” with very little rain. Any wastewater from TMT will be collected and transported down the mountain.

Eliminating Waste – No waste from TMT will be left on the mountain.   In addition, we will recycle and reuse solid and non-hazardous water materials as much as possible.

Ensuring Safe Operations – Multiple safety measures will reduce the potential for accidental spills of hazardous materials, including leak detection systems, daily inspections of equipment that handles hazardous materials and a detailed Spill Prevention and Response Plan.

Reducing Visibility – TMT is not sited at the top of Maunakea, but on a lava plain below the summit, specifically chosen to minimize its environmental impact. A special reflective aluminum-like coating reflects the sky and reduces the visibility of the structure. It is only visible from 14% of Hawaii Island, or where 15% of the population lives.
