TDEC Seeks to Amend Praxair Permit

By Walter F. Roche Jr.

Tennessee environmental officials have issued a new and amended permit to a Greene County firm to correct a typographical error contained in the original permit issued several months ago.
The amended permit was issued by the Tennessee Department of Environment and Conservation to Praxair Inc, a company that supplies liquid carbon dioxide to the beverage industry.
The permit issued by TDEC in February left out the word "shall" in a section setting a limit on the allowable visible emissions from the company's Midway manufacturing operations. The omission had the effect of eliminating the limit.
"Visible emissions from this facility shall not exhibit greater than 20 percent," the amended permit states.
The permit limits Praxair to the production of 90,789 tons of liquefied carbon dioxide in any 12 month period.
Praxair is one of three firms occupying a Midway site. The original occupant, US Nitrogen, produces ammonium nitrate and related products for its parent company, Austin Powder, an Ohio based explosives manufacturer.
The third firm, which has yet to go into operation is Yara Inc., a manufacturer of calcium nitrate.
