PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
a. Volume of wastewater: 0.090 MGD (Design Capacity)
b. What is the current permitted capacity: 0.090 MGD
C. Actual treatment capacity of current facility (current design capacity): 0.090 MGD
d. Date(s) and construction activities allowed by previous ATCs issued in the previous two
years: There have been no ATCs issued for this facility in the past two years.
e. Description of existing or substantially constructed W WT facilities: a bar screen
followed by a flow equalization tank, dual aeration tanks, dual clarifiers, a tertiary sand
filter, tablet chlorine disinfection (dual units) with contact tank, an aerated sludge
holding tank, dechlorination, a flow measuring device with totalizer, post aeration, and a
portable stand-by power generator.
f. Description of proposed W WT facilities: There are no W WT facilities proposed at this
time.
PART III - OTHER PERTINENT INFORMATION
1. Special monitoring requests: No additional monitoring is being recommended at this time.
Compliance history: This facility has a consistent compliance record for the past twelve
months.
PART IV - EVALUATION AND RECOMMENDATIONS
Aqua North Carolina (the permittee) has requested renewal of the subject permit. There have
been no changes to the permit and/or the W WTP since the permit was last renewed nor are any
proposed at this time.
The Windemere development currently consists of a mixture of condominium and single family
units located on the shores of Lake Norman. This development has not built -out as quickly as
originally thought, which has resulted in the existing W WTP averaging less than half of it's daily
design capacity. Additional residential construction (outside of the Windemere development) has
generated some additional flow, however, the WWTP is nowhere near design capacity.
Pending receipt and approval of the draft permit, and concurrence by the Division of
Environmental Health, itis recommended that the NPDES Permit be reissued.
