Greeneville, TN — US Nitrogen

UPDATED: 02/07/2014 — see Change Log

OWNER: US Nitrogen (owned by Austin Powder)
PROJECT: Greenfield ammonium nitrate plant

New 73,000 2015

NOTE: The groundbreaking took place on February 17, 2012; at that time, production was expected to start in March 2014. In February 2014, US Nitrogen submitted new water permit applications in an attempt to resolve ongoing uncertainty regarding water supply and discharge at the plant; these applications have yet to undergo review and public comment, making a 2014 start-up date unlikely.

The end product is ammonium nitrate, which will be used by the plant’s owner, Austin Powder, in the industrial explosives market. The greenfield project consists of two ammonia plants (with a capacity of 100 tons per day each), a nitric acid plant (500 tons per day), and an ammonium nitrate solution plant (635 tons per day). Yara has filed air permits for a 72,000 ton per year calcium nitrate plant on the US Nitrogen property; Yara will purchase its nitric acid feedstock from US Nitrogen. There are also plans to build a carbon dioxide liquefaction plant on the site.

FEEDSTOCK: Natural gas
END PRODUCTS: Ammonium Nitrate, Nitric Acid

ADDRESS: 471 Pottertown Road, Midway, Tennessee, 37809, United States

    We don’t want US Nitro, Austin Powder, Yara or any other plant in East Tennessee to come in here and pollute the Nolichucky River and destroy this region. Shame on you demons. Your day is coming….

    This is a grave mistake, allowing these people to slip in here under a cloak of secrecy. Why all the secrecy, who us YARA. Why weren’t all people living in all counties,, using or bordering the Nolichucky notified? This company has had many, many problems and fines. Their ties with Lebanon and Muammar al-Gaddafi is extremely troubling to me. google YARA, check out all the lawsuits and payoffs. Smells like a you’re being placed in an extremely dangerous position, for a few jobs! Beware!

    I’m a ‘Neighbor’ of USN, and apparently, Yara, and the other proposed factory to be brought in… I STRONGLY OPPOSE these companies coming into MY NEIGHBORHOOD and polluting my air, my water, my land & my life… Not to mention endangering the lives of my family, my neighbors & my friends… We the people of Midway were not even given the opportunity to have a say in this intrusion on our beautiful home… You have come in here in taken our beauty away, run off our wildlife animals my child & grandchildren loved to watch… You are all nothing but liars & have nothing but the mighty dollar in sight… NOT THE WELL BEING NOR CONCERNS FOR WE THE PEOPLE THAT HAVE MADE THIS HOME FOR MANY GENERATIONS…. And your so called events that we were all invited to. We weren’t … Your trucks drove thru my dead end road, didn’t stop once except to turn around to leave back out… You never intended for the local population to know a fact one nor be informed enough to tell you, NO !!! I say ” GO AWAY ! WE DON’T WANT YOU HERE ! NOT ALL OF US CAN BE BOUGHT WITH YOUR DIRTY MONEY ! WE LOVE OUR HOMES & OUR LAND & COUNTY… WE DO NOT LIKE YOU ! LEAVE OUR COUNTY ALONE OR BUILD IT IN YOUR OWN BACK YARD LIKE YOU ARE IN MINE ! AND TELL YOUR FAMILY IT IS SAFE & OKAY… THEY WOULD NOT BUY THE LIES EITHER… “

    Now that Industrial Developmental Board has gotten the property back from US Nitrogen the taxpayers are liable for the clean up if there is an explosion. Also there has not been and Environmental Impact Statement submitted to my knowledge which is the law…check out this web link to see the actual members of the IDB listed by the Greene County Partnership website….Election time this year and I hope the communities exercise their right to vote. If they can buy the water from Old Knox Utility then they should have to do that not get free water from the Nolichucky and then pollute it.

    Many citizens in Greene County oppose this plant being located there, as do many of us who live in neighboring counties. We do not need another source of pollution to our air and water in Northeast Tennessee. This company has been underhanded and not forthcoming from the beginning. The people of this region deserve to know the truth about the handful of dirty jobs that will be bought at the cost of our air and our water and that of our children. We have roots here that run deep and we do not want US Nitrogen or Austin Powder here.

    As I see, many of others agree with me, my family, and my friends. We have a cabin that is literally right beside the Nolichucky River. We are downstream about two miles from the intake and outfall that US Nitrogen/Austin Powder will be putting into the river. The meetings that have been held exposed the fact that Ammonia and Nitrate would both be put into OUR river, ONE of the TWO rivers that are not polluted, YET! What they didn’t say is that other hazardous chemicals will also be put in the river. The pollution that may be put into this river will not affect us, but it will affect our children, our grand children, their grand children, and our future generations. We need all the help we can get to make sure that this horrid operation does not have OUR water polluted!!!!!
