Woodville Wind Turbine Project to Reduce Emissions, Provide Community Aid

Woodville’s newly installed wind turbines.

Our Magnesia Specialties Woodville, Ohio lime operation entered into an agreement in late 2021 intended to decrease
the site’s greenhouse gas emissions and provide valuable community assistance for decades to come. The agreement with
industrial power company One Energy has resulted in the installation of three wind turbines to the division’s Woodville,
Ohio, operation. Construction on the project commenced in 2022 on a reclaimed section of the property, and was
completed at the end of 2023. The equipment, each of which stands about 260 feet tall and features three 143-foot
blades, came on line in April 2024.

Once operational, the turbines immediately helped the Woodville plant meet its energy needs. Though their impact will
vary from month to month based upon seasonal weather conditions, in their first 9 months of operation, the turbines
generated almost 7.2 million kilowatt hours (kWh), or enough energy to power approximately 600-700 average-sized
homes. We estimate that this resulted in 3,265 metric tonnes of avoided Scope 2 GHG. As noted, we have not reflected
this avoided GHG in our Scope 2 calculations for 2024 but will do so in future years.
