Dear Mr. Lamm:
In accordance with your application for a discharge permit received on February 18, 2014, we
are forwarding herewith the subject certificate of coverage (COC) to discharge under the subject state -
NPDES general permit. This permit is issued pursuant to the requirements of North Carolina General
Statute 1.43-215.1 and the Memorandum of Agreement between North Carolina and the US
Environmental Protection Agency dated October 15, 2007 (or as subsequently amended).
Please note that groundwater standards in 15A NCAC 02L and 02T regulations must also be met
for closed -loop recycle systems or any discharges to groundwater.
Please note that this COC does not cover discharges from the irrigation of raw material
stockpiles, a wastewater, from this site. This condition is a result of the information presented in your
application.
Please note that permit requirements in Part 11, Section A, numbers 1-5, and Part 11, Section B,
number 1 are no longer valid per NC Session Law 2011-394. However, note that Part II, Section A,
number 6, and Part 11, Section B, numbers 2-10 are unaffected by this Session Law. Those sections will
remain in effect for the duration of this permit term. Please be reminded thatyour facility must notify the
appropriate DWQ Regional Office at least 72 hours in advance of operation of your wastewater treatment
facility,
This certificate of coverage is not transferable except upon approval of the Division of Energy,
Mineral, and Land Resources (DEMLR). If the facility changes ownership or is closed,DEMLR may require
modification or revocation and reissuance of the certificate of coverage. This permit does not affect the
legal requirements to obtain other permits which may be required by DEMLR, or permits required by
other federal state or local authorities.

DEER WATER DUALITY

PROJECT DESCRIPTION
This project consists of the permitting of stormwater and wastewater discharge from a concrete
ready mix plant located near Murphy, North Carolina.
SITE DESCRIPTION
The site is located on a previous concrete ready -mix plant located at 395 Wingate Road, near
Murphy, North Carolina. Site topology consists of previously graded benched areas for a
previous concrete ready -mix plant. The site slopes from the northwest to southeast. The lowest
area is along the southeastern property line. The Notelly River, a Class C watercourse, is the
receiving waterbody and hies to the south 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 El imination 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 NOl application.
FINDINGS
To comply with NPDES requirements, Brooks Engineering Associates, PA (BEA) has provided
engineering plans dated February 5, 2014 that depicts the necessary infrastructure required.
Effluent limits for the current site configuration can be achieved through a recycle system and a
water mass balance. The truck washdown area will be 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. Runoff from
stockpile areas is diverted to an existing retention pond to provide additional settlement of any
suspended solids. 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. Wastewater will be skimmed from the top and flow into a 7,500
gallon storage tank. Wastewater from the 7,500 gallon tank will be pumped by manual control
panel operation to the existing concrete production system. A high water alarm will be installed to
warn when the tank reaches 85% capacity. The 7,500 gallon storage tank has been sized 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 1412 gallons. The storage tank has been sized to
accommodate surplus water until it can be recycled into plant operations. The existing retention
pond on site will be slightly excavated to create additional storage for process wastewater if

necessary. All total suspended solids and pH are contained on site. A Stormwater Pollution
Prevention Plan (SPPP) will be written as required by the NPDES permit in concurrence with the
proposed plan.

Wastewater Basin Volume (V) = 1267 ft2 x 0.513 ft 650 ft'
or 4862 gal
Total V = Wash down Volume + Rainfall Volume = 120 gallons + 4862 gallons
Total Volume to Recycle System = 4982 gallons
Total volume to System: 4982 gallons
Total Storage Provided: 7500 gallons

Concrete Production Water Usage Calculation
Average Daily Production of Concrete (yds.) 105 yds.
Water Required per yd, of concrete (gallons) 34 gallons
Average Daily Production Water Use: 3570 gallons
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
4982 gallons - 3570 gallons 1412 gallons
Recycle Time: 0.4 days
Note: Retention pond will have the capacity to store all volume going to 7500 gallon tank if necessary.

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 a1 upper bounds
are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
Please refer to NOAA Atlas 14 document for more information.
