NPDES Permit No.: NCG520110
PART I - GENERAL INFORMATION
1. Facility and address: Moss Lake Dredging Operations
City of Kings Mountain
Post Office Box 429
Kings Mountain, NC 28086
2. Date of investigation: June 28, 2011
3. Report prepared by: Michael L. Parker, Environmental Engineer II
4. Person contacted and telephone number: Steve Killian, Planning Director, (704) 734-
4596.
5. Directions to site: From the jct. of Hwy. 150 and Airport Road just north of the Moss
Lake Reservoir, travel northwest on Airport Road 0.2 mile. The proposed dredging
operation will be located on the left (south) side of Airport Road. The site is accessed via
a paved access road.
6. Discharge point(s): Latitude: 35° 19' 36"
Longitude: 81° 28' 26"
USGS Quad No.: F13SW
7. Receiving stream or affected surface waters: Buffalo Creek/Moss Lake Reservoir
a. Classification: WS-III
b. River Basin and Subbasin No.: Broad 030805
c. Describe receiving stream features and pertinent downstream uses: The point of
discharge will occur 0.5 mile above where Buffalo Creek enters Moss Lake.
The discharge point is immediately below a rock spillway that was once used as a
water supply source for a nearby mill. The receiving stream at this point is 20
feet wide and 6 - 12 inches deep. Stream dimensions are likely to change once the
dredging operation begins.

PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Actual treatment capacity: 0.007140 MGD (Design Capacity)
b. Current permitted capacity: N/A (new permit)
c. Description of existing or substantially constructed WWT facilities: There are no
existing WWT facilities.
d. Description of proposed WWT facilities: The applicant proposes to construct an
earthen settling basin with skimmer to treat the water prior to discharge.
e. Possible toxic impacts to surface waters: There are no toxic impacts expected.
2. Compliance Background: N/A (new facility).
PART III - OTHER PERTINENT INFORMATION
1. Special monitoring or limitations (including toxicity) requests: N/A (General Permit)
PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, City of Kings Mountain (the City), requests approval to construction a
settling basin and associated discharge from a sand dredging operation proposed near the
headwaters of Moss Lake. The City owns the lake and for years has dealt with accumulations of
sand and silt that continues to be deposited in the upper reaches of the lake. Past attempts to
remove sand deposition in the main body of the lake have met with varying degrees of success,
so the City is looking at trying to capture as much of the sand and silt as possible before it enters
the lake.
The City plans to use a long -reach trackhoe to gain access to the material as it is carried
down the creek. The material will be pulled from the creek and allowed to drain into the settling
basin where the ancillary water will be treated and discharged. Once the material has dried, it
will be removed from the site.
The proposed site was once used as a sand dredging operation in the past; however, the
previous operation did not have a point source discharge and no discharge permit was required.
The current site has limited area, which may become problematic for the City should the amount
of deposition recovered exceed the amount of storage area available. It will also be important to
maintain the existing basin from accumulating excess material which would reduce settling
efficiency, especially since it is not baffled and is limited to a single basin. This Office
recommends issuance . the permit as requested.

Notice Of Intent
National Pollutant Discharge Elimination System application for coverage under
General Permit NCG520000: Sand Dredging operations and similar point source
discharges
Gentlemen;
Please find enclosed an application for coverage of the project listed above under General
Permit NCG52000. This site will be used to remove sand deposits from the upper end of
Moss Lake, which is our water supply reservoir. Moss Lake has seen heavy
concentration of sand and sediment being deposited into upper end of the reservoir. This
intent of this operation is to limit the amount of material that will be added to the current
sediment deposits. The material will be removed on an as needed basis, based on the
level of sand and sediments that are accumulated in front of the access area.
The skimmer basin design is under reviewed by NCDENR- Land Quality
The following items are enclosed for your review and approval.
• Copy of the check for $100 made payable to NCDENR
• 3 copies of county map with location of facility clearly marked on map
• 3 copies of a portion of the Waco 7.5 minute series USGS topographic
map showing the discharge location.
• 3 copies of the completed application
• 3 sets of mine map and specifications prepared for the mining permit.
• A statement concerning an Alternatives analysis for the .ro'ect.

NCG520000 Application Additional Information
Site Usage
This project involves the removal of accumulated sand and sediment from the upper reaches of
Moss Lake, which is the City's water supply reservoir. Moss Lake has seen heavy concentration
of sands being deposited into upper end of the reservoir. This intent of this operation is to limit
the amount of material that will be added to the current sediment deposits. The material will be
removed on an as needed basis, based on the level of sands that are accumulated in front of the
access area.
The material will be removed from the reservoir using a trackhoe. The material will be allowed
to dewater and drain into a skimmer basin to treat the ancillary water associated with the sand
dredging operations and the stormwater from the stockpile areas. Once the material is dry, it will
be removed from the site. The material is mostly a sandy material with some silt and trash. All
material will be removed from the site.
Alternate Analysis
There are not any structures that have process water on site. The skimmer basin collects the
stormwater and ancillary water on the site. The location, size, and terrain of the site do not
allow any alternate forms of treatment available for the stormwater and ancillary water on the
site. The configuration of the tract and the site's proximity to the stream prevent the use of
subsurface and spray irrigation systems. There is not a public sewer system in the area, but since
the skimmer collects stormwater, most Municipal or Regional Sewer Collection System would
not permit the flows from the skimmer basin to be added to their system.
