Physical Location
Facility and address: Berryhill Elementary School
% Charlotte -Mecklenburg Schools
3301 Stafford Drive 10501 Windy Grove Road
Charlotte, NC 28208 Charlotte, NC 28278
2. Date of investigation: February 19, 2010
3. Report prepared by: Michael L. Parker, Environmental Engineer II
4. Person contacted and telephone number: Richard Rizzo, [phone]
5. Directions to site: From the jct. of Olde Dowd Road and Walkers Ferry Road in western
Mecklenburg County, travel southwest on Walkers Ferry Road = 2.0 miles to the WWTP
site. The plant site is on the left (east) side of the road and on the south side of the
school grounds.
6. Discharge point(s): Latitude: 350 12' 41"
Longitude: 800 59' 56" USGS Quad No.: G15NW
7. Receiving stream or affected surface waters: Lake Wylie
a. Classification: WS-IV, and B
b. River Basin and SubbasinNo.: Catawba 030834
C. Describe receiving stream features and pertinent downstream uses: The discharge
is into a cove of Lake Wylie (Paw Creek arm). This area of the lake receives
frequent bodily contact through various water recreational activities. No other
downstream dischargers are known.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
a. Actual treatment capacity: 0.006 MGD (Design Capacity)
b. Current permitted capacity: 0.006 MGD

Y'
Page Two
C. Description of existing or substantially constructed W WT facilities: The existing
W WT facilities consist of a bar screen, a flow equalization basin, an aeration
basin, dual secondary clarifiers with sludge return, an aerated sludge holding tank,
chlorine (tablet) disinfection, and dechlorination.
d. Description of proposed WWT facilities: There are no proposed W WT facilities at
this time.
Possible toxic impacts to surface waters: Chlorine is added to the waste stream,
however, dechlorination is provided.
2. Compliance Background: This facility has maintained a generally good compliance
history with only a few record keeping deficiencies noted in the past few years. A CEI
was performed at this facility on November 17, 2009, by MRO and MCWQP staff, and
with the exception of a few minor deficiencies, the W WTP was in excellent operational
condition.
PART III - OTHER PERTINENT INFORMATION
Special monitoring or limitations (including toxicity) requests: None at this time.
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee (Charlotte -Mecklenburg Schools) has requested renewal of the subject
permit. There have been no changes to the permit nor the W WTP since the permit was last
renewed nor are any proposed during this renewal. At one time there was some discussions
between the school system and Charlotte -Mecklenburg Utilities to end sewer service to this area
and eliminate the existing discharge. At the present time, there are no plans to serve this area
with sewer, therefore, continued operation of the W WTP will be necessary.
Pending a final review by the NPDES Unit, it is recommended the permit be renewed as
requested.
