Vinyl chloride is not just an Ohio problem. More than 5 tons are emitted into the air in North Carolina each year.
In 2020, air permit holders in North Carolina emitted 5.5 tons of vinyl chloride — the same chemical that was released from rail cars during a train derailment in East Palestine, Ohio, earlier this month.
To illustrate the magnitude of that environmental disaster, an estimated 550 tons of vinyl chloride was released in East Palestine one week, according to a lawsuit filed against Norfolk Southern, the railroad owners. That’s 100 times more than North Carolina emits into the air in a year.
A known carcinogen, vinyl chloride is a colorless gas with a sweet odor that burns easily. It is used to make plastics, but it can be emitted from other sources, including landfills, paper mills and wood product manufacturers.
In North Carolina, vinyl chloride emissions increased by 20% from 2017 to 2020. Landfills are the largest source of emissions, primarily because microbes breakdown chlorinated solvents present in the waste — plastics, degreasers, spot removers, even cosmetics. Of the top 20 emitters statewide, 17 of them are landfills.
The Sampson County Landfill, which already carries the dubious distinction of ranking second in the nation in methane emissions, also led the state in vinyl chloride air releases: 3,224 pounds — or 1.6 tons. That figure is a 61% increase since 2017. That uptick coincides with the 25 tons-and-counting of garbage rotting in the landfill, which accepts waste from 44 counties.
Here are the top 10 landfills for vinyl chloride emissions, in pounds, for the Year 2020. Figures are from the NC Department of Environmental Quality’s air quality division. Facilities in bold indicate they are located in predominantly communities of color, neighborhoods where at least 30% of residents are low-income, or both.
