NCG140000 N.O.I.
Further explanation, if necessary: *A series of 4 sediment basins and a pond have been installed to
reduce the potential discharge of pollutants including solids and high pH process water.
A CO2 pH control system will be installed. The system is designed to provide for the recycling of
truck wash water and harvesting of process and storm water for that purpose.
Further notes.
Wash -down is an exterior wash of the truck, hopper, chute (-50 gallons).
Wash -out is a washing of the interior of the drum requiring a larger volume of water (-150 gallons)
and removal of solids that is typically accomplished at the end of the vehicle work day.
13) Will your facility spray -down or actively wet aggregate piles?
❑ No X Yes Note. Recycled water may be used to supplement the wetting of aggregates.
14) Does the facility use any of the following on site?
❑ Phosphorus -containing Detergents
❑ Brighteners X Other Cleaning Agents
X Non -Phosphorus -containing Detergents
❑ Other:
15) Are wastewater treatment facilities planned in the 100-year flood plain?
X No ❑ Yes
16) Does your facility use or plan to use a recycle system, or recycle components in your treatment system?
X Yes ❑ No
If yes, what size storm event is the system designed to hold before overflowing? (for example, 10-yr, 24-hr)
NIA year, 24-hr rainfall event. We will be utilizing recycled process water from our sediment basins
and collection pond and harvested stormwater for washing our trucks and equipment as well as for
dust control and pad washdown.
17) Will your facility build a closed -loop recycle system that meets design requirements in 15A NCAC 02T
i yE .1000 and hold your facilities' working volume'?
❑ Yes X No
Will your facility discharge wastewater to surface waters?
X Yes ❑ No
If the facility's treatment system meets the design requirements of 15A NCACO2T .1000 (including holding
the 25-year, 24-hour storm plus one foot of freeboard), holds the working volume of your site, and does
not discharge wastewater to surface waters, you may not be required to obtain an NPDES permit for
wastewater discharges. If you believe this is the case, please contact DEMLR's Aquifer Protection Section
Land Application Unit Central Office Supervisor or staff (1636 Mail Service Center, Raleigh, NC 27699-1636)
for more information on obtaining the necessary permits or approvals. If you will discharge wastewater or
stormwater to surface waters, please continue to apply for a permit to discharge associated with ready -mixed
concrete or like operations under NCG140000. For further questions, please contact DEMLR's Stormwater
Permitting Unit Staff.

Why or Why not? See above.
What is the feasibility of employing a subsurface or surface discharge as compared to a direct
discharge to surface waters?* See above.
e) Direct Discharge to Surface Waters: Is discharge to surface waters the most environmentally sound
alternative of all reasonably cost-effective options of the wastewaters being considered?*... X Yes ❑ No
i) If No, contact DEMLR's Land Application Unit to determine permitting requirements.
f) If this review included all wastewater discharge types, would excluding some types (e.g. raw
stockpile wetting) make any of the above non -discharge options feasible? .............. ❑ Yes X No
* You may be asked to provide further information to support your answers to these questions after the initial review.
Feasibility should take into account initial and recurring costs.
