Dear Mr. *)evey:

i In acsordance with the Federal Water Pollution Control Act Wts of 1972, we are nearing the final stages of processing your application for a permit to dischstge weates to navigable waters.

To assure that the public notice and the NPDES permit contais current data, please review the above referenced application and, if necessary, update it to refleet current wastewater treatment conditions at the plant.

Our preliminary evaluation of thermal effects ladicates that we have i insufficient data to assure you that a possibility exists for this facility

, to quality for a 33 ' "tver with regard to the thermal component of your l discharge. Howeve ,,,e intend to ask for a 316(a) waiver for this 1 facility, please aae us in your reply. In order to support such a waiver  :

and to develop aff1 seat limitations, monitoring requirements and implementa-tion schedules, the atras hi addltional information and data are required

! in duplicate and should be mailed within 30 days of receipt of this notifica-i tion. You may also submit any additional information yee have available. l

A cover letter signed by the Applicaat's Authorised Agent for permit correspondance stating that to his beat knowledge the information is i accurata. east accompany this additional informatiaa.

i If you hare any questions, please contact ze at 404/526-2328.
