Minor Permit Modification Request tgie144,4, _.--
Dear Mr. Belnick, /-2,11-1/
I.would like:to request a-modification to the Town of Pittsboro's NPDES permit NC0020354. The request is to allow
for an alternate,placement of our effluent composite sampler from its current location at the bottom of the cascade
post aerator, to a point just upstream and after the UV system. The current location does not provide a representative
sample of both effluents to Robeson Creek and our reclaimed water distribution system. Our current reclaimed water
permit allows us to use the NPDES permit-required samples to satisfy the reclaimed permit requirements. When then
reclaimed water pump is running, there is very little water going down the cascade aerator and the composite sampler
is pulling from the very bottom of this channel. Our current location/sampling method is contradictory to proper
sampling protocol and has a tendency to collect effluent that is not representative of our discharge to Robeson Creek.
Mandy Hall, WWTP Consultant of the Raleigh Regional Office has recently visited our facility to review our
sampling techniques. If you have further questions, please contact Ms. Hall at [phone] or myself at (919) 5481
2444. Thank you for your consideration.
