Getting your Trinity Audio player ready...

Until a large residential community just outside of Fort Mill, SC learned that the Canadian Silfab solar panel manufacturing plant intended to move into our community and set up shop 1300 feet from two new schools that will contain 2500 students, most of us would have told you that we thought solar power was a good thing. None of us had a clue at the time that green energy production requires some of the most toxic chemicals and produces some of the most toxic AIR pollutants you can find; with some that can kill or permanently injure you with just a small exposure. The raw materials used are heavily dependent on China and child labor for production of these solar panels.

Since this would be the first solar panel manufacturing business in South Carolina, many residents started digging into what solar panel production meant and what was involved. We were stunned at the toxic and explosive chemicals they intended to bring into an area built as a distribution center zoned as light industrial.

DHEC held a public hearing on Oct 30th, 2023 where a large number of people in the community came out to oppose and question the wisdom of putting something so toxic next to two new public schools, right behind the DMV and within a 2-mile radius of a senior community and large residential communities and nearby retail centers.

Toxic Chemicals

The next course of action is to see whether DHEC will approve their air pollution permit which would include approving these and other toxic chemicals being put into our air:

TolueneIt is a DHEC Category 3 pollutant, the most dangerous category of all. DHEC’s definition of Category 3 pollutant – high toxicity – those pollutants which may cause chronic effects that result in death or permanent injury after very short exposure to small amounts. The plant will use 132 gallons per year of Toluene with an unknown amount kept on site.

Hydrogen Fluoride (HF)– a very poisonous, highly irritating, and corrosive colorless gas. It is fatal when inhaled, swallowed, or comes in contact with the skin. It is a DHEC Category 3 pollutant. Two 7,925-gallon tanks of HF will be refilled weekly. The Fire Dept. requires a ½ mile evacuation radius. HF will be released at 88% of the concentration limit, assuming Silfab’s estimates are correct.

Silane – a highly flammable, colorless, pyrophoric, toxic gas with a sharp pungent smell. Silane will be stored on-site in a 22,983-gallon tank (unknown total use). It is highly explosive and “may explode when exposed to air”. This plant is of major concern if you have school children. This plant is only 1300 feet (about ¼ mile) from two new schools with 2500 children. The Fire Department’s ERG (emergency response guide) shows the minimum evacuation radius as one mile assuming the tank is about 8,000 gallons. Silfab’s tank is 3 times that size. So, should the evacuation radius be 3 miles?

Additional air pollutants will include the following:

Volatile Organic Compounds (VOCs) Silfab is projected to release the threshold limit of 100 tons per year into our air.

Hydrochloric Acid (HCl) – Even though HCl is a category 1 pollutant; the 8.21 tons per year is 82% of the allowable threshold volume of any single toxic pollutant that would cause Silfab to be classified as a major source of pollution.

No one knows what the combined effect of the cocktail of pollutants that will be released into our air will be. As we know, air does not stay in one place and will move around our community. The children in the schools next door will be breathing this toxic cocktail daily while at school and if they live nearby they could be breathing this toxic cocktail 24/7.

Each of these toxic pollutants are regulated individually. No one knows what the combined effect of the cocktail would be if there was an explosion of one tank that would likely lead to the explosion of all tanks. The pollutants that are planned are highly toxic and explosive and clearly belong in an industrial area with at least a 1-mile buffer where the public is protected from any mishap or breakdown of equipment.

One final note, what about all the trucks that will be required to deliver these deadly chemicals on our roads? That plant is only 2 miles from Carowinds, an enormous amusement park and the trucks must come through the most congested roads in Fort Mill to refill the tanks. Has anyone really thought this through? We need some good old fashioned common sense to put a stop to this nightmare.
