Flawed Data Cited in TDEC Letter

By Walter F. Roche Jr.

Citing "flawed data" used by state environmental officials, an eastern Tennessee activist is calling on the agency to reopen its investigation of a complaint of odors emanating from industrial sites.
In the letter to the Tennessee Department of Environment and Conservation, Park Overall of Afton states that the dismissal of the complaint was based on "flawed and inaccurate information."
Overall calls on the agency to reopen its investigation stating that the conclusion that US Nitrogen or Scepter could not have been the source of the odors was based on false assumptions about the force and direction of winds on Dec. 4, the date the odors were recorded by local resident Sherry Arnold.
Overall said it appears that TDEC based its conclusion on the assumption that the wind gusts on that day were the same all day.
She wrote that the TDEC conclusions failed to include actual observed conditions throughout the day in question.
She said that data of actual conditions obtained from another source showed a wide variation from the standard assumed by TDEC and that a 12 hour period of relative calm before the reading TDEC relied on could have caused a build up of emissions.
"The complaint of malodorous emissions during the overnight and morning period of calm winds which immediately preceded the complaint,"the letter states.
Arnold's complaint was one of several submitted to TDEC over the past several weeks. TDEC concluded the reports were unfounded but referred one of them to the state Health Department
