US Nitrogen Submits Test Plans

By Walter F. Roche Jr.

A Greene County chemical firm has submitted a 15-page document detailing how tests will be conducted to determine if the Midway facility is operating in compliance with permits issued by the Tennessee Department of Environment and Conservation.
US Nitrogen LLC, which manufactures ammonium nitrate and related products, submitted the details of how tests will be conducted to show compliance limits for emissions of ammonia and visible emissions. The tests will be conducted by a third party, AMP Cherokee Environmental Solutions.
The US Nitrogen submission also provides a detailed description of the three step process of manufacturing nitric acid, a key component in the process.
According to the filing the test will determine if the company's pollution control equipment including a selective catalytic reduction unit adequately controls nitrous oxide and related emissions.
The testing document states that the process produces nitric acid by combining nitrogen dioxide and nitrogen tetroxide with water.
Under the permit US Nitrogen is limited to the production of 600 tons of nitric acid per day. Under the test protocol a minimum daily production level of 451 tons.
A series of charts and diagrams show where AMP Cherokee will collect samples to determine compliance.
