Groundbreaking occurred on April 8, 2011, and the plant became operational in April 2016, costing approximately US$2.5 billion and making it the largest-ever single private investment in the state of Tennessee. In June 2017, a US$150 million secondary expansion was announced that would allow the plant to manufacture
pyrogenic silica. This expansion was completed in October 2019, adding 50 new jobs to the plant.
Safety issues and incidents
*In October 2012, two subcontract workers fell to their death resulting in a temporary suspension of construction activities. The subcontracting company was later found to be at fault.
*A Tennessee Occupational and Safety Administration (TOSHA) inspection conducted in March 2016 resulted in a fine of US$3,500 for regulatory violations over the control of hazardous energy.
*A second TOSHA inspection conducted in August 2016, resulted in a fine of US$4,000 for issues stemming from process safety and respiratory equipment.
*On August 30, 2017, 5 workers were hospitalized with chemical burns following a discharge of

During the event, seven local residents, and a plant worker were transported to a local hospital with unspecified injuries.
A firefighter and four sheriff's deputies were also treated for heat-related symptoms and later released. The following day, officials from TOSHA announced a temporary shutdown of the plant pending investigation.
Five days later, an environmental sensor detected elevated levels of an unnamed substance prompting a shelter-in-place order for emergency workers involved in cleanup efforts within the facility.
During the explosion event, local officials instructed residents to shelter indoors with their windows closed and HVAC systems turned off. Nearby residents complained of respiratory distress, as well as an odd taste in their mouths. This led to speculation in both local and social media that the cloud contained high-concentration hydrochloric acid, despite media reports to the contrary.
For the week following the event, there was little-to-no communication from Wacker management or government officials, resulting in further speculation about hazardous chemicals being released into the environment. Wacker management later issued a full-page letter stating that no hazardous chemicals were released. One and a half weeks later, Bradley County Emergency Management Agency Director Troy Spence held a press-conference attempting to allay fears, and urging residents to sign up for the county's non-emergency text-messaging service.
