US Nitrogen is asking Tennessee environmental regulators to approve yet another change easing the limits on a permit governing its controversial ammonium nitrate manufacturing facility in Tennessee's Greene County.
In a petition filed Monday with the Tennessee Department of Environment and Conservation, the company asked the state agency to double the number of flare start up hours allowable for each circuit of ammonium train start up.
The request argues that the change will not result in any increase in emissions "but will significantly enhance US Nitrogen's operating flexibility."
The petition follows another report filed by USN with TDEC showing that while the company discharged more than 2.4 million gallons of water in the Nolichucky River in February, it withdrew no water from the river during that period.
That official report came despite a press notice issued by the company that it attained "full capacity" during that same period.
Company officials have not responded to repeated requests for comment on their start-up efforts.
In another recent filing US Nitrogen officials cited adverse market conditions as a cause for delays in the actual full operation of the Tennessee facility.
