Permit No: NC0021504
Montgomery County
Dear Mr. Blake :
Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted
on October 22, 2003. The Compliance Evaluation Inspection was conducted by Belinda S. Henson of the
Fayetteville Regional Office. The facility was found to be in Compliance with permit NC0021504. The
cooperation of Mr. David Asbill, ORC and Mr. Sam Stewart, Backup ORC were greatly appreciated.. As a
reminder preservation of the Waters of the State can only be acquired through consistent NPDES permit
compliance.
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.
Sincerely,

Section ID: Summary of Findings/Comments
The Town has two (2) hosiery industries and one (1) casting and molding industry.
The facility is in the planning stages of possible regionalization with other wastewater facilities in the
County.
The manual bar screen appeared to be operational. The bars should be 3/8 to'2 inches apart to adequately
remove debris. Some screenings were located on the ground. A recommendation would be to improve
containment of the screenings to eliminate them from reaching the ground. All screenings are
disposed of through the County landfill.
The two (2) aeration basins were operational. All aerators were operational. A spare aerator was
operational in basin #1 at the time of the inspection. Facility staff was in the process of repair of one of the
aerators.
The clarifier sludge depth was one (1) foot with eight (8) feet of tank depth. The staff is wasting from the
clarifier based on sludge depth exceedance above 1 foot , settleability and Mixed Liquor Suspended Solids
(MLSS).
The chlorine contact tank had 9 — 12 inches of sludge in it. As a reminder the chlorine contact tank should
be cleaned at least at one (1) foot of sludge.
The effluent appeared to be free of solids. The effluent outfall was easily accessible.
The grounds were neat and clean.
The existing pond is not utilized in treatment. The facility continues to have spill over fi-om the pond into
the chlorine contact tank when excessive amounts of rainfall occurs and the level of the pond rises.
The sludge thickener is used to thicken waste activated sludge (WAS) before pumping to the four (4) sand
drying beds. The sludge thickener contained approximately IA of the tank volume of sludge. Two (2) beds
were empty and two (2) had sludge in them. A few weeds were noted on the beds with sludge. All sludge
is disposed of through the County landfill.
The effluent flow meter (Milltronics OCM III) was calibrated March 3, 2003 by Jim Haven, Inc. Instrument
and Control Service.
The following field parameters are completed onsite by facility staff: pH, Temperature, DO, and Residual
Chlorine. A field inspection checklist for the field parameters was completed during the records review
and will be forwarded to our Laboratory Certification Unit. The pH standard for 10 expired August
2003, as a reminder the standard should be replaced by a new one immediately. The remaining
NPDES permit required parameters are completed by "Similabs".
All maintenance, operational, and ORC logs were reviewed and appeared to be neat and in order.
Laboratory records were reviewed for the following months: February, March, and April 2003 and
compared to Discharge Monitoring Records (DMRs). All records reviewed appeared to be correct..
A compliance evaluation for the period August 2002 through August 2003 revealed one (1) ammonia
monthly exceedance.
