A Greene County chemical firm has filed a nine-page response to a recent report from state environmental officials citing deficiencies in its operations.
In the response from US Nitrogen, Plant Manager Dylan Charles wrote that revisions in operating procedures and changes in equipment have or will shortly correct all the deficiencies including missing records.
Charles said the the calibration of flow meters had been simplified "to avoid confusion" and the company will no longer rotate the two existing meters.
The state surveyors had noted that company records made it unclear which flow meter was in use at any given time.
Charles added that US Nitrogen had also hired a consultant to perform a second calibration review.
Tennessee Department of Environment officials, who made a limited on-site review, also had noted that the number of outfalls where stormwater runoff is monitored had been increased to 10.
In his response, Charles said the added outfalls were established to monitor runoff in areas where the company has begun applying sludge. The sludge is produced at a water treatment plant where Nolichucky River water is treated prior to its use in the manufacturing process.
He said US Nitrogen's Best Management Practices Plan had been update to include the additional outfalls.
Other items addressed in the letter include revisions in water sump pump management and replacement of riprap on the site to prevent erosion.
