Facilities of Chaparral Steel Chaparral is the nation's 10th
largest steel mill, and is owned by TXI. Chaparral takes scrap metal,
including many, many autos, and uses electric arc furnaces to melt them down
into construction forms. Chaparral produces hazardous waste in the form of
lead, zinc and cadmium dust that is now transported off-site for
disposal/recycling.
However, there are two hazardous waste landfills from past years of
on-site disposal. It also produces "fluff," which is what the non-metal
"innards" of the autos are called. This "fluff" has been dumped in the TXI
quarry where it has caught fire at least twice in the last eight years.
There are some German studies showing steel mills and fluff fires to be
significant dioxin pollution sources. The non-metal fluff dump site in the
TXI quarry had higher levels of metals like cadmium and lead in the soil
than the CKD also dumped in the quarry, according to TXI-sponsored testing
for the recent permit. There is also Cesium-137 dust stored on-site from an
accidental acceptance of radioactive scrap material that was melted down.
