RE: Edge Water Treating, LLC —NPDES NC0004944 Modification Application
Dear Mr. Chernikov:
Dewberry is pleased to submit the enclosed permit modification application package on behalf of Edge
Water Treating, LLC. Edge Water Treating is requesting permit modification for operation of the
wastewater treatment plant (WWTP) as a Centralized Waste Treatment (CWT) facility Subcategory D —
Multiple Wastestreams.
The WWTP historically served the DuraFiber Technologies facility and treated sanitary wastewater,
process wastewater associated with Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF)
manufacturing, and stormwater associated with industrial activity. Edge Water Treating, LLC wishes to
operate the facility as a CWT. Edge Water Treating intends to accept metals bearing wastes, oil wastes,
and organics wastes. Therefore, the facility wishes to be permitted under 40 CFR 437.40 Subpart D —
Multiple Wastestreams. In addition to offsite waste, the WWTP will continue to treat sanitary wastewaters
From the adjacent manufacturing space. The intent is to lease the manufacturing space so there will be
future process and utility wastewater from tenants.
Edge Water Treating anticipates the flow rate of the facility to gradually increase over time. To account for
the gradual increase in flow, Edge Water Treating is requesting the NPDES permit include multiple flow
tiers at 0.50 MGD,1.o MGD, and 2.305 MGD. The existing wastewater treatment system has a design
flow of 2.305 MGD.
Enclosed are the following application forms and supporting documentation:
• Form 1
• Map —Form 1 Item XI Attachment
• Form 21)
• Line Drawings (3) — Form 2D Item III-B Attachment
• Initial Certification Statement (4o CFR §437.41(a))
We appreciate your consideration. Please feel free to contact me at 919-424-3764 with any questions
regarding this application package.
Sincerely,
Leigh -Ann Dudley, PE
Project Manager

Attach to this application a;topographic map of the area extending to at least one mile beyond property boundaries. The map must
show the outline of the facility, the location of each of its existing and proposed intake and discharge structures, each of its
hazardous; waste treatment, storage, or disposal facilities, and each well where it injects fluids underground. Include all springs,
rivers and other surface water bodies in the map area. See instructions for precise requirements.
XII. NATURE OF BUSINESS (provide a brief description
The wastewater treatment facility will operate as a Centralized Waste Treatment facility permitted under
Subcategory D — Multiple Wastestreams. Activities which generate the wastewater will be varied. In addition to
offsite CWT wastewater, adjacent leased manufacturing space will generate process, utility, and domestic
wastewater. Tenants have not been identified as of this application, so the nature of the business generating these
waste streams is unknown.
XIII. CERTIFICATION see instructions

Cr Use the space below to list any of the pollutants listed in Table 2D-3 of the instructions which you know or have reason to believe will be
discharged from any outfall. For
every pollutant you list, briefly describe the reasons you believe it will be present.
1. Pollutant
2. Reason for Discharge
Cresol
Cresol was indentified by the EPA as a pollutant of concern for
oil and organics wastestreams. As the facility intends to accept
this type of waste this compound may be present.
Vanadium

metal bearing wastestreams, As the facility intends to accept this
type of waste this compound may be present.
Xylene was idenfied by the EPA as a pollutant of concern for
Xylene
organics wastestreams. As the facility intends to accept this type
of waste this compound may be present.
Carbon disulfide was identified by the,EPA as a pollutant of
Carbon disulfide
concern for organics and metal bearing wastestream. As the
facility intents to accept this type of waste this compound may be
present.
Strontium

VII. Other Information (Optional)
Use the space below to expand upon any of the above questions or to bring to the attention of the reviewer any other information you feel should be
considered in establishing permit limitations for the proposed facility. Attach additional sheets if necessary.
Section III -A flow rate estimates have been provided for the three requested flow tiers of 0.5
MGD, 1.0 MGD, and 2.305 MGD. Flow estimates have been provided based on the current best estimate
of the contribution from flow sources. Onsite sanitary wastewater is based on an estimate of 100
employees and a typical usage of 25 gallons per day per employee (15A NCAC 02T.0114). The offsite
septage estimate is based on accepting 10 trucks per day at 2,700 gallons per truck. The
stormwater flow contribution is based on the average flow reported by DuraFibers for Outfall 005
on the 2013 NPDES permit renewal application. Flow rates for onsite tenant process and utility
wastewater and the offsite CWT wastewater are estimates based on potential contributions as
facility operations increase over time.
For Section V-A, the estimated effluent pollutant concentrations are representative of the CWT
wastestreams only. The average estimated pollutant concentrations for parameters noted with Source
3 are based on the Long Term Average pollutant concentrations from the Development Document for
Effluent Limitations Guidelines and Standards for the Centralized Waste Treatment Industry - Final
(EPA 821-R-00-020). The long term average concentrations were selected based on the facilities
sampled which use the treatment technology options used by the EPA as the basis to develop the
NSPS limits for each subcategory: Metals Option 3, Oils Option 9, and Organics Option 4. Maximum
daily estimated concentrations are based on the product of the long term average and the parameter
one day variability factor.
No long term average or variability factor were determined by the EPA for chemical oxygen demand
(COD), total organic carbon (TOC), and ammonia. The ratios of COD to biochemical oxygen demand
(BOD) and TOC to BOD for the Organics Option 4 data was calculated. The BOD long term average and
daily maximum concentration estimates were multiplied by the COD/BOD ratio to estimate the COD
average and daily maximum concentration. The BOD long term average and daily maximum concentration
estimates were multipled by the TOC/BOD ratio to estimate the TOC average and daily maximum
concentration.
Ammonia effluent concentrations are estimated based on data collected by the EPA from the Organics
Option 4 facility and presented in the Development Document for Effluent Limitations Guidelines
and Standards for the Centralized Waste Treatment Industry - Final (EPA 821-R-00-020).
Effluent temperature estimates are based on winter and summer historical discharge data from the
Salisbury Rowan WWTP from June 2015 - April 2016. Effluent data from the Salisbury Rowan WWTP was
selected as this facility is located in close proximity to the Edge Water Treating facility and is
therefore in the same climate. Assuming no significant heat inputs from process and CWT
wastewaters, we expect the biological treatment systems to operate at similar ambient seasonal
temperatures.
