Dear Ms. Slaughter :
Enclosed please find a copy. of the Compliance Evaluation Inspection form from the inspection conducted
on February 10, 2004. The Compliance Evaluation Inspection was conducted by Belinda S. Henson, Dale
Lopez and Don Register of the Fayetteville Regional Office. The cooperation of Mr. Robert Ellis, Grade IV

found to be in Compliance with permit NC0020656.
Please respond to the following items in writing to our office by March 31, 2004 explaining the corrective
actions taken to resolve the issues:
1) Repair of three (3) influent pumps
2) Bar screen clogging due to excess grease flowing through the headworks
3) Grease balls floating on the surface of the effluent in the chlorine contact tank
4) Industrial Waste Survey (IWS) forms should be submitted to the following industries: Scotland
Container and the new industry (that produces the soap product) to assist the City with operating the
wastewater facility and to continue with NPDES compliance. As a reminder it is stated in the
NPDES permit Part III Section C. Pretreatment Programs 2. Industrial Waste Survey -``The
permittee shall update its Industrial Waste Survey (IWS) to include all users of the sewer collection
system at least once every five years".
Please refer to the enclosed inspection report for additional observations and comments. If you or your staff
have any questions, please call me at 910-486-1541.

In response to the inspection conducted on February 10, 2004 we have addressed the
following items explaining the corrective actions, below.;
1. During the inspection the (3) influent pumps were primed and started while you
r
were on site during the inspection
2. Enclosed please find a customer pamphlet that we::distribute to' the customers to
educate the citizens on whatnot to put in our, sewer system to hopefully eliminate
excess grease flowing in our head works:. We are -also implementing a Fats, Oil
and Grease Ordinance which we areenclosing to hopefully eliminate future
problems such as this.
3. We are making some modification to the skimmers on the clarifiers to help
eliminate the amount of water that is running off of the skimmer toward the inside
weir that will -prevent the vortex action that is causing the grease to go up under
the inside weir:' which allow the grease to enter the contact chamber. If this does
not eliminate the problem' we plan to extend the length of the inside weir at the
skimmer box.
4. We have submitted the Industrial Waste Survey short form to Scotland Container
and the Industrial Waste Survey long form to Qual-Pak (formerly Abbott). As
soon as we receive the completed forms we will forward them to your office.
