Comment: Employee Training not documented. Plan not updated to show upgrades
to plant. Also need to add property across the street, as it has been used to dump
influent from pump station once during emergency situation. Will not be used on a
regular basis, but the potential for a similar situation is present. All outfalls drain to
common downstream point of stream along property and can be used; however, should
a problem show up, the cause could be attibuted to an off-site/upstream source. This
should be considered when deciding to monitor each outfall separately, or just the one
common downstream point.

CERTIFIED MAIL RETURN RECEIPT NUMBER: 7005 3110 0004 2491 41 13
Description of Collection System:
The Thomasville sanitary sewer collection system is currently comprised of a system of 209.35 miles, or
1,105,367 feet of pipe, and 28 sewage lift stations spread throughout the area.
Description of Treatment Process:
Hamby Creek WWTP is a 4.OMGD capacity grade 4 wastewater treatment facility using the activated
sludge process with post aeration. Headworks equipment consists of solids shredding and grit collection
and removal. Primary treatment uses two circular clarifiers equipped for removal of raw sludge and
floating solids. Secondary treatment consists of two high rate trickling filters followed by single stage
extended aeration activated sludge. Removal of activated sludge is accomplished in three circular
secondary clarifiers equipped for rapid removal of solids for return to process. Post aerated effluent
receives chlorination for disinfection prior to discharge into Hamby Creek. Raw and waste activated
sludge are belt pressed and landfilled or anaerobically digested to standards for class B sludge as defined by
EPA in CFR Part 503 then applied to farm land as a beneficial reuse.
II. PERFORMANCE
In 2007 Hamby Creek WWTP treated 934.5 Million Gallons of wastewater at an average daily flow of
2.56 MGD. The plant was out of compliance for BOD in January, February, March, April, May, June,
July, August, September, October, and December; for ammonia in February, March, April, May, June,
July, August, September, October; for TSS in April, and June; for pH in November; for chromium in April;

_, w
for selenium in May and August; and for fecal coliform in January. The inability to provide sufficient
oxygenation has caused most of the operational problems by resulting in inhibition of the biological process
leading to the BOD and ammonia violations. Additionally, lack of a functional heating and mixing system
in the digesters has limited sludge disposal methods, causing solids to build up beyond normal levels in the
plant process. Construction of the upgraded / expanded plant facility which began in March, 2006 has
continued steadily and benefitted from the dry weather experienced in 2007. Completion of the new
facilities should aid in resolving most operational difficulties in meeting permit parameters.
III. MONTHLY REPORT 2007

Hi Corey,
We received an NOI from Thomasville's Hamby Creek WWTP (Davidson Co.) for coverage under
NCG110094. They discharge stormwater to North Hamby Creek, a Class C water in the Yadkin
basin.
The NOI is attached. Does the Winston-Salem Regional Office have any concerns
with issuing a COC to this facility? If we don't receive any objections in 30 days, we plan to issue the
COC.
Thanks,
BG
