'

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
