Cabarrus County
Dear Mr. Wood:
. This letter is in reference to your application for an NPDES permit for the Hillgrove
Water Treatment Plant. In the Division of Environmental Management's acknowledgment
letter to you dated March 30, 1993, we stated that we needed: (1) An engineering proposal,
(2) a statement of the delegation of authority, and (3) an Engineering Economic Alternatives
Analysis. We requested this information within thirty days of receipt of that
acknowledgment and, to date, we have not received these items. Therefore, we are
returning your application. Enclosed please find the application materials submitted for
renewal. Application fees are non-refundable according to North Carolina Administrative
Code 15A NCAC 211.0105 (b)(1).
If in the future, you determine that you wish to operate a wastewater discharge
system, you must first apply for and receive a NPDES Permit. Discharging wastewater
without a valid NPDES Permit will subject the discharger to a civil penalty of up to
$10,000 per day. -If you have questions regarding this matter, please -contact Susan
Robson at _(919) 733-5083.
Sincerely,

PART I - GENERAL INFORMATION
._1. Facility and Address: Hillgrove WTP
c/o City of Concord
Post office Box 567
Concord, N.C. 28025
2. Date of Investigation: April 13, 1993
3. Report Prepared By: Michael L. Parker, Environ. Engr. II
4. Person Contacted and Telephone Number: Rick Wood, Water
Plant Supervisor, [phone] ext. 244
5. Directions to Site: The existing WTP site is at 51 Palaside
Drive in the City of Concord.
6. Discharge Point(s), List for all discharge Points: -
Latitude: 350 25' 3 7 "
Longitude: 800 35' 44"
Attach a__.USGS Map Extract and indicate treatment plant site
and discharge point on map.
USGS Quad No.: F 16 NE
r
7. Site size and expansion area consistent with application.
Yes.
`8. Topography (relationship to flood plain included): Hilly,
5-15% slopes.. The WTP is not located in a flood plain.
9. Location of Nearest Dwelling: Several within 500 feet of
the point of discharge. The closest dwelling is approx. 150
feet from the proposed discharge point.

10. Receiving Stream or Affected Surface Waters: U. T. to
Threemile Branch
a. Classification: C
b. River Basin and Subbasin No.: Yadkin 030712
C. Describe receiving stream features and pertinent
downstream uses: The receiving -stream is actually the
discharge from two private fish ponds connected in
series approx. 100 feet above the proposed point of
discharge. The stream channelis well defined, which
suggests stream flow exists on a frequent basis. Flow
was observed at the time of the site inspection. This
stream passes in close proximity to many residences
prior to it's junction with the main segment of
Threemile Branch.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of Wastewater: 0.250 MGD,(Design Capacity)
b. What is'the current permitted capacity: N/A
c. Actual treatment capacity of current facility (current
design capacity): 0.250 MGD
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: The existing WWT facilities consist of
two alum sludge settling basins.
f. Description'of proposed WWT facilities: N/A
g. Possible toxic impacts to surface waters: A study by
DEM regarding WTP effluents has found a variety of
concerns (toxicity from chlorine, aluminum, etc.) that
warrant further attention. The WLA should address the
concerns documented by the study.
h. Pretreatment Program (POTWs only): N/A
2.- Residual handling and utilization/disposal scheme:
a. If residuals are being land applied specify DEM Permit
No. N/A.
Residuals Contractor: N/A
Telephone No. N/A
b.-- Residuals stabilization: N/A
C. Landfill: Residuals will be disposed of in a private
county landfill.
d. Other disposal/utilization scheme (specify): N/A

Page Three
3. Treatment Plant Classification: Less than 5 points; no
rating (include rating sheet). This facility does not meet
the minimum criteria for a Class I facility.
4. SIC Code(s): 4941
Wastewater Code(s):
Primary: 21
5. MTU Code(s): 50001
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant
Funds or are any public monies involved (municipals only)?
Public monies were used in the construction of the WTP.
2. Special monitoring or limitations (including toxicity)
requests: None, pending receipt and approval of the WLA.
3. Important SOC/JOC or Compliance Schedule dates: N/A
4. Alternative Analysis Evaluation
a. Spray Irrigation: Insufficient area available.
b. Connect to regional sewer system: This is the current
means of disposal of the alum sludge, however,
surcharges imposed by the County has made this option
uneconomical. Supernatant from the settling basins was
returned to the raw water basin for reprocessing,
however, recent changes in DHS regulations now
prohibits this option.
C. Subsurface: Insufficient area available.
d. Other disposal options: N/A
PART IV - EVALUATION AND RECOMMENDATIONS
As a result of a directive from the DHS, Concord's Hillgrove
WTP must eliminate the recycling of supernatant from their alum
sludge settling basins back into their raw water basin.
Surcharges by the County (who controls the WWTP) makes it
economically unfeasible to discharge this water into the sewer
collection system. The City has chosen to apply for an NPDES
Permit and discharge this water to surface waters. The DHS
directive (prohibiting supernatant recycling) has prompted other
WTP's in this region to examine alternatives to recycling. Some
are considering a discharge to surface waters as their option.

.Page Four
Some concern exists regarding the proposed discharge and the
potential for human contact with the wastewater. Residential
development lines the receiving stream, and potential for contact
with the wastewater is increased. P&E and TSB should determine
whether this discharge would pose any risk to persons that may
come in contact with the wastewater.
P&E should also determine whether it is permissible (due to
economic circumstances) to allow a facility such as this to
create a discharge to surface waters when access to a municipal
sewer is readily available. Since other WTPs may be affected by
this directive from DHS, a decision on this facility may also
affect future NPDES Permit applicants.
Provided the above concerns can be satisfactorily resolved
in favor of a discharge, it is recommended that an NPDES Permit
be issued.
