Stan / Rick,
Please review the attached NOI application and let me know of any recommendations for the permit. I will forward you
a copy of the site plan via mail. They plan to only have a sw discharge; and use a CLRS for the ww. They have not
applied for a CLRS permit from DWR.

Thanks so much for your help. If you need any more info, give me an email or call. If you could send me a
recommendation for the permit by 4/28/2017 so I can issue their COC, I'd greatly appreciate it.
Have a great day!

PROJECT DESCRIPTION
This project consists of the permitting of stormwater and wastewater discharge from a concrete
ready mix plant located near Fletcher, North Carolina.
SITE DESCRIPTION
The site is located on a mostly cleared 2.9 acre parcel located at 264 Mills Gap Road, near
Fletcher, North Carolina. The site currently consists of a level graded site area. Site topology is
slightly sloping from Mills Gap Road to rear of property. The site slopes from the northeast to
southwest. The lowest area is along the southeastern property line. Hoopers Creek, a Class C
watercourse, is the receiving waterbody and lies to the southeast of the subject property.
Stormwater discharge from the site to receiving waterbody is routed through ephemeral drain -
ways.
PURPOSE
The purpose is to obtain a NPDES General Discharge Permit NCG 140000 to discharge
stormwater and wastewater under the National Pollutant Discharge Elimination System (NPDES)
and to obtain an Authorization to Construct (ATC) to implement the necessary infrastructure to
comply with NPDES requirements.
PROCEDURES
To discharge stormwater/process wastewater under the NPDES a Notice of Intent (NOI)
application is to be submitted to the North Carolina Department of Environment and Natural
Resources (NCDENR). Engineering plans and other pertinent data are to be submitted as
designated in the NOI application.
FINDINGS
To comply with NPDES requirements, Brooks Engineering Associates, PA (BEA) has provided
engineering plans sealed March 2, 2017 that depicts the current existing conditions. Effluent
limits for the current site configuration can be achieved through a recycle system and a water
mass balance. The truck washdown area has been graded to allow all site process wastewater to
be collected in a single small basin area; all other surface water will bypass the wastewater basin
and be treated as stormwater. The stockpile areas are located within an isolated area and consist
of material that has already been washed and will not be wetted down. The truck washdown area
will collect all material from the truck and drum washdown into a ramped wastewater collection
basin that will allow all heavy material and settable solids to settle out. The settling basin final
bay can store 7767 gallons at full capacity. Wastewater from the settling basin final bay will be
pumped by manual control panel operation to the existing concrete production system. The
existing settling basin meets storage requirements from calculations for the 25 year, 24 hour
storm event and maximum daily water use classified as wastewater. Calculations have been
provided as Attachment "A". From the calculations provided there is a water balance surplus of
601 gallons. The settling basin can accommodate surplus water until it can be recycled into plant
operations. All total suspended solids and pH are contained on site and reused for concrete. A
Stormwater Pollution Prevention Plan (SPPP) will be written as required by the NPDES permit in
concurrence with the proposed plan.

Daily Water Use Calculations
Daily Maximum Number of Trucks: 7 trucks
Wash down Water Usage: 15 gallons/truck
7 _ trucks x 15 gallons/truck = 105 gallons
Rainfall Volume Calculations
Note: The precipitation estimate (in.) for a 25 year, 24 hour storm for 35.43 N, 82.48 W (subject site)
is 5.95 in. (0.496 ft) per the "Precipitation - Frequency Atlas of the United States" NOAA Atlas
14, Volume 2, Version 3.
Wastewater Basin Area: 1600 ft2 (see site plan for further detail)
Wastewater Basin Volume (V) = 1600 ft2 x 0.496 ft 794 W
or 5936 gal
Total V = Wash down Volume + Rainfall Volume = 105 gallons + 5936 gallons
Total Volume to Recycle System = 6041 gallons
Total volume to System: 6041 gallons
Total Storage Provided: 7767 gallons
% Storage Used: 78% %

Water Balance Calculation (For a 25 year, 24 hour storm event and Average Daily Production)
Total Water = Total Volume to Recycle System - Average Daily Production Water Use
6041 gallons - 5440 gallons = 601 gallons
Recycle Time: 0.1 days

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates
(for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds
are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
