TDEC Waives 2nd USN Permit Requirement

By Walter F. Roche Jr.

Tennessee environmental officials have concluded that US Nitrogen LLC does not need a permit to utilize three 20,000 gallon sump pump water tanks.
In a letter sent today Tennessee Department of Environment and Conservation manager James P. Johnston wrote that, based on data submitted by US Nitrogen, the use of the tanks will have an "insignificant" effect on the environment.
The approval marks the second time in recent weeks that TDEC has waived permit requirements for the Midway chemical company. The state gave its okay on April 30 to USN's use of a 52,250 tank to be utilized in producing an ammonium nitrate and water solution. The solution will be 57 percent ammonium nitrate and 43 percent water.
In the letter sent today to Dylan Charles, the USN plant manager, Johnston wrote said that based on USN's data, the tanks would emit less than five tons per year of air contaminants and less than 1,000 pounds of hazardous air contaminants annually.
In its application USN said that the water the tanks will hold will be no more than five per cent ammonium nitrate. They will each be 13.67 feet in diameter.
As he did in approving the other waiver, Johnston closed by stating that the company must comply with all applicable air pollution regulations.

A Greene County chemical firm withdrew nearly 25 million gallons of water from the Nolichucky River in the month of April, according to a report filed with the state.
U.S. Nitrogen LLC reported it pumped 24.6 million gallons from the river a substantial increase from the 18.9 million gallons the company reported for March.
The report submitted today to the Tennessee Department of Environment and Conservation shows that on seven days during the month the company withdrew more than 1.4 million gallons from the riverway. On April 1, no water was withdrawn.
The same report shows a total of more than 10 million gallons was discharged back into the river during April. The highest discharge, over 600,000 gallons, came on April 6.
In March the company reported discharging 11.7 million gallons back into the Nolichucky. There was minimal discharge on six days of the month.
On 12 days the discharge exceeded 400,000 gallons.
Under its permits with TDEC the company is required to file monthly reports on its river water use. The water is pumped from the river through a 12 mile pipeline to its Midway facility.
In April the company pumped nearly 25 million gallons from the river and discharged a little over 10 million gallons. Contact: wfrochejr999@gmail.com
