A Level B model was developed for Site A. The BOD5 limit is effluentty limited.
The NH3-N limit was based on protecting against instream ammonia toxicity. The minimum
instream D. O. concentration (6.49 mg/L) is predicted to be at the outfall and D. O. concentrations
should recover to background levels within 0.12 miles of the outfall. Stream flow characteristics
for the receiving stream were derived from regional equations developed by USGS for hydrologic
area 10.

Parameter(s) are water quality limited. For some parameters, the available load capacity of
the immediate receiving water will be consumed This may affect future water quality based
effluentlimitations for additional dischargers within this portion of the watershed.
•A
No parameters are water quality limited, but this discharge may affect future allocations.

PART I - GENERAL INFORMATION
1. - Facility and Address: Lowe's Distribution Center
% Lowe'S Companies, Inc.
Post Office Box 1111
North Wilksboro, N.C. 28656
2. Date of Investigation:
September 14, 1995
3. Report Prepared By: Michael L. Parker, Environ. Engr. II
4. Person Contacted and Telephone Number: Michael L. Slusher,
P.E., Ed Powell, [phone].
5. Directions to Site: From the jct. of I-77 and SF. 1890
(Tomlin Mill Rd.), travel east on SR 1890 x 1.1 miles. The
entrance to the Lowe's site is on the right side of SR 1890.
6. Discharge Point(s), List for all discharge Points: -
Site A Site B
Latitude: 350 54' 34" Latitude: 350 55' 25"
Longitude: 80° 49' 46" Longitude: 80° '49' 22"
Attach a USGS Map Extract and indicate treatment plant site
and discharge point on map.
USGS Quad No.: D 15 NE
7. Site size and expansion area consistent with application:
Yes. Sufficient area exists for the construction of the
proposed WWTP.
8. Topography (relationship to flood plain included):
Considerable grading has reduced the site topography from
rolling to relatively flat. The site is not located in a
flood plain.
9. Location of Nearest Dwelling: Approx. 800 to 1000 feet from
the WWTP site.

10. Receiving Stream or Affected Surface Waters: Patterson - SzTc e3
Creek and a MONO& _ S;,-c p
a. Classification: C. (for both streams)
b. River Basin and Subbasin No.: Yadkin 030704
C. Describe receiving stream features and pertinent
downstream uses: U. T. to Pocky Creek - good flow was
observed in the receiving stream at the proposed
discharge point. Significant site grading upstream has
resulted in changes to upstream topography. No
downstream users known. Patterson Creek - significant
drainage area. Upstream users include North Iredell
H.S. The area is predominately rural with agriculture
being the primary use.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
a. Volume of Wastewater: N/A (Design Capacity)
b. What is the current permitted capacity: N/A
C. Actual treatment capacity of current facility (current
design capacity): N/A
d. Date(s) and construction activities allowed by previous
ATCs issued in the previous two years: N/A
e. Description of existing or substantially constructed
WWT facilities: There are no existing WWT facilities.
Description of proposed WWT facilities: The applicant
proposes to construct an extended aeration WWT facility
consisting of the following WWT units: a bar screen,
equalization basin, aeration basin, a clarifier,
tertiary filters (subject to the receipt of a WLA),
sludge holding tank, and tablet disinfection.
g. Possible tonic impacts to surface waters: Chlorine will
be added to the waste stream. No dechlorination is
proposed.
h. Pretreatment Program (POTWs only): Not Needed.
2. Residual handling and utilization/disposal scheme: There was
no residual disposal scheme submitted with the Permit
application. A residual disposal scheme must be received and
approved prior to the approval of the ATC.
3. Treatment Plant Classification: Less than 5 points; no
rating (include rating sheet). Expected to be a Class II,
pending receipt of ATr_. request (NPDES Permit should reflect
a minimum of class II monitoring).
4. SIC Code(s): 4225
Wastewater Code(s): 02
5. MTU Code(s): 05100

PART III - OTHER PERTINENT INFORMATION
1.* Is this facility being constructed with Construction Grant
Funds or are any public monies involved (municipals only)?
No
2. Special monitoring or limitations (including toxicity)
requests: None at this time.
3. Important SOC/JOC or Compliance Schedule dates: N/A
4.. Alternative Analysis Evaluation: The applicant evaluated
four (4) wastewater disposal alternatives in the Engineering
Economic Analysis (EEA) that was submitted to the Division.
Connection to a municipal sewer system was not found to be
feasible because municipal sewer was not within reasonable
access to the site. Subsurface disposal (conventional septic
tank and LPP) were evaluated and were not chosen due to the
minimal area available for installation. Spray Irrigation
was not chosen due to the reasons noted above as well as
limitations due to current buffer restrictions and
topography. Surface drip irrigation.was not evaluated in the
EEA.
It is the opinion of this staff that even though -suitable
soils existed on the subject site, the applicant's engineer
"prepared" the EEA to fit what the applicant wanted as its
No. 1 choice: a discharge from a package WWTP. This choice
will minimize site disturbance and, more importantly reduce
"expected" permitting time (lengthy permit turn around time
with the DEH is a well known fact). Furthermore,
"anticipated costs" of the,non-discharge options as detailed
in the EEA also appear to be inflated (the $578,000 cost for
a 0.016 MGD septic tank system seems fairly exorbitant!).
Such being the case, it is our opinion that the applicant
did -a poor job of planning for their wastewater disposal
needs; especially since the site contains soils that are
perfectly suitable for an on -site disposal system.
PART IV - EVALUATION AND RECOMMENDATIONS
The applicant has chosen two (2) proposed discharge
locations (identified as site A & B in the EEA submitted by the
applicant). The receiving stream at site A (U. T. to Rocky Creek)
Appears to have good stream flow, however, there is concern as
the effect on the upstream drainage area since the topography has
been significantly altered as a result of site grading. This
grading could have either positive or negative impacts on stream
flow. In any case, the proposed location at site A remains a
possibility, although it is recommended that the outfall be
extended down to where the U.T. joins Rocky Creek so as to help
off -set any possible negative impacts upstream grading may have
had on stream flows (both winter and summer).

Page Four
Site B (Patterson Creek) appears to be very suitable for a
possible discharge due to the excellent stream flow resulting
from a significantly larger drainage basin. The discharge
location is at a point on the stream which has a rocky bottom
that would provide excellent mixing/aeration of the effluent.
After examining the recently promulgated WLA, it appears
that sufficient stream flow exists at both locations to support
the proposed discharge. However, as a result of concern over
upstream drainage (topography) changes at site A and, should the
applicant choose to discharge at site A, it is recommended that
the outfall line be extended downstream to a point where the U.T.
joins the main segment of Rocky Creek (the applicant's engineer,
Mr. Powell, has indicated that this option is available).
