US Nitrogen Submits Emissions Test Data

By Walter F. Roche Jr.

US Nitrogen LLC today submitted over 100 pages of test data which it says shows the company's emissions monitoring devices are functioning properly.
The Greene County chemical firm had the tests performed on it nitric acid plant by AMP Cherokee Environmental Solutions, according to the filing. A second firm, Southern Air Solutions was also involved in the tests performed at the Midway TN facility on June 8.
The company also submitted its monthly report on the amount of water pumped from the Nolichucky River. The amount used, 28.8 million gallons was the highest so far this year. In the 118-page emmisions montoring report, dozens of test categories were listed and all marked as valid.
The report states that US Nitrogen is a "nitrogenous fertilizer manufacturer".The company had not previously described itself as a fertilizer manufacturer but stated the ammonium nitrate was shipped to other locations for use in the production of explosives.
According to the report the company uses a Selective Catalytic Reduction device to control nitrous oxide emissions and catalytic decomposition for N20 emisions control.
The report states that the tests were performed in accordance with standards set by the U.S. Environmental Protection Agency. Attached to the report are a half dozen appendices.
It also states that the original AMP report was "modified" by US Nitrogen and another outside firm, Ensafe.
In the monthly river report the company, a subsidiary of Ohio based Austin Powder, said it drew 28.8 million gallons from the river in June. On 16 separate days during the month it drew more than 1 million gallons.
The highest daily total was 1.2 million gallons pumped from the river on June 19. The June figures compare with May when about 21 million gallons were pumped from the Nolichucky for use in the production of ammonium nitrate.
The report states that 13.6 million gallons of waste water were discharged back into the river during June. On 15 days during the month more than 500,000 gallons were discharged into the Nolichucky. The highest single day discharge of more than 700,000 gallons came on June 17.
