US Nitrogen LLC is asking Tennessee environmental officials to conclude that two new pieces of equipment, a water pump and compressor, are insignificant sources of emissions and thus exempt from requiring a permit.
In a letter to officials of the Tennessee Department of Environment and Conservation, Dylan Charles, the company's plant manager, said each of the sources would produce less than 1,000 pounds per year of hazardous pollutants.
The request marks the second time this year the company has sought such an exemption. In May TDEC agreed that the use of three 20,000 gallon sump pump water tanks did not require a permit.
In both the latest request and the prior one, the company has provided no details on how the equipment will be used. Though it is not explicitly stated in the request the equipment will apparently be used somewhere on the company's Greene County manufacturing site.
According to the request submitted today, the Sullair portable air compressor is powered by a 275 horsepower Caterpillar engine. The trailer mounted water pump is powered by a 74 horsepower engine.
Charles wrote that the air compressor will be used on a standby basis while the water pump will be used periodically. Emissions of non-hazardous substances will be less than five tons per year, according to the letter.
