nuisance conditions, the Permittee shall take immediate corrective action, including those as may
be required by this Division, such as the construction of additional or replacement wastewater
treatment or disposal facilities.

This request for construction approval has been reviewed that will include a belt
filter press, two (2) 500 gallon polymer mixing tanks and appurtenances with 9.6 dry
tons/day of solids processing capacity.
This equipment will allow PPG to process solids 3 days/week on one shift (24
hours/week) and dispose of all the generated solids at current production levels. If
necessary the equipment could be operated 140 hours per week. PPG will retain their
land application permit which gives them maximum operating flexibility. We fully
support their attempt to initiate this upgrade at the earliest possible time. This upgrade
will not require any modification of the NPDES permit. Should you have any questions,
please call me at 336-771-4969.
