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 437.4o 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 2D
• Line Drawings(3)—Form 2D Item III-B Attachment
• Initial Certification Statement(40 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,

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 BOO 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.

RE: Initial Certification Statement for NPDES Permit NC0004944
Mr.Chernikov,
Edge Water Treating,LLC operates an existing wastewater treatment plant located in Salisbury,NC. Edge
Water Treating wishes to operate the facility as a Subpart D Centralized Waste Treatment(CWT)facility
and accept metals bearing,oily,and organics wastes. As required by 4o CFR§437.41(a)for Subpart D
facilities,Edge Water Treating,LLC is submitting herein the Initial Certification Statement. A NPDES
permit modification request has been submitted under separate cover.
§437.41(1)List and describe the subcategories of wastes accepted for treatment at the facility
At this time,the Edge Water Treating facility has not identified the specific wastes that will be accepted;
however,the facility anticipates accepting waste in the following categories:
• Metals Subcategory
o Metal finishing rinse waters
o Air pollution control blow down
o Waste acids and bases with or without metals
o Alkaline and acid solutions used to clean metals parts or equipment
• Oils Subcategory
o Oil-water emulsions or mixtures
o Interceptor wastes
o Aqueous and oil mixtures from parts cleaning operations
• Organics Subcategory
o Landfill leachate
o Solvent bearing waste
o Still bottoms
o Tank clean-out from organic,non-petroleum sources
Edge Water Treating will include a description of additional subcategories that may be accepted in the
future within the required Period Certification Statement(§437.41(b)).

NC0004944 Initial Certification Statement, July 18, 2018 page 2
§437.41(2)List and describe the treatment systems in-place at the facility and conditions under which
the treatment systems are operated for the subcategories of wastes accepted for treatment at the facility
Figure i attached presents a Block Flow Diagram of potential anticipated treatment systems.The Edge
Water Treating facility is an existing wastewater treatment plant that historically treated wastewater from
an Organic chemical,Plastics,and Synthetic Fibers(OCPSF)industry which is now no longer at the site.
The core wastewater treatment plant includes equalization,two aeration basins,three clarifiers,one
aerobic sludge digester,and sludge filter press.In addition,the facility has various tanks,clarifiers,filters,
advanced oxidation system,and anaerobic treatment system.Edge Water Treating intends to evaluate use
and potential repurpose of existing equipment versus installing new equipment.While at this time it is
not clear if existing or new equipment will be used,presented below are potential anticipated treatment
processes.These treatment processes are consistent with the technologies selected by the EPA as the basis
for establishing limitations and standards for each waste subcategory.
Metals Subcategory
Edge Water Treating anticipates treating metals subcategory wastes in a system which may consist of
selective metals precipitation,secondary precipitation,solid-liquid separation,tertiary precipitation,and
final clarification.The specific pH set points for each precipitation stage will be selected based on the
metals targeted for removal,but are anticipated to be between 8-10.The selection of hydroxide or sulfide
based precipitants will be based on the specific wastes.
Depending on the waste stream(s),multiple precipitation steps may be implemented. In this event,after
each precipitation step,precipitated solids will be removed via clarification prior to initiating the next
precipitation step.Multiple stages of precipitation may be achieved in a single batch reactor with the
ability to remove solids from the reactor between precipitation steps or may be performed in a series of
reactors and clarifiers.Additional treatment chemicals such as caustic and sulfuric acid may be used to
meet pH set points.Coagulants and flocculant aids may be used to assist with liquid-solid separation.
After treatment,metals waste may be comingled in the equalization basin with organics waste and treated
oil wastes or could bypass the biological treatment system. The specific equipment will be selected upon
evaluation of the operability of existing infrastructure and identification of waste streams.The proposed
treatment process is consistent with the technology option,Option 3,selected as the basis for the metals
subcategory limitation and standards for New Source Performance Standards(Development Document
for Effluent Limitations Guidelines and Standards for the Centralized Waste Treatment Industry—Final
EPA 821-R-oo-o2o).
Oils Subcategory
Edge Water Treating anticipated treating oils subcategory wastes in a system which may consist of
emulsion breaking,gravity separation,and dissolved air flotation.The specific emulsion breaking
chemical will be selected based on the waste to be treated. Non-emulsified wastes may not be treated with
the emulsion breaking chemical and may be discharged directly to gravity separation.After gravity
separation,wastes may be discharged to a dissolved air flotation(DAF).The DAF system may consist of a
flocculation step which maybe a slowly mixed tank or flocculation tubes.The system may include
chemical feed systems for polymer addition when needed.The detention time in the DAF will be selected
based on the time required to achieve acceptable separation for each waste.After treatment,oil wastes
will be comingled with organics waste and treated metals waste in the equalization basin.
The proposed treatment process is consistent with the technology option,Option 9,selected as the basis
for the oils subcategory limitation and standards for New Source Performance Standards(Development
Document for Effluent Limitations Guidelines and Standards for the Centralized Waste Treatment
Industry—Final EPA 821-R-00-020).

NC0004944 Initial Certification Statement,July 18, 2018 page 3
Organics Subcategory
Edge Water Treating anticipates treating organics subcategory wastes in a system which may consist of
equalization followed by biological treatment.The equalization tanks and biological wastewater treatment
system are existing processes at the Edge Water Treating facility.Operating conditions for the biological
treatment system such as food to mass ratio,mixed liquor suspended solids,sludge age and pH will be
selected based on the composition of the equalization tank wastewater.
The proposed treatment process is consistent with the technology option,Option 4,selected as the basis
for the organics subcategory limitation and standards for New Source Performance Standards
(Development Document for Effluent Limitations Guidelines and Standards for the Centralized Waste
Treatment Industry—Final EPA 821-R-oo-o2o).
§437.41(3)Include information and supporting data establishing that these treatment systems will
achieve equivalent treatment
Edge Water Treating anticipates utilizing the treatment technologies used by the EPA to develop the basis
for the limitations and standards and therefore has demonstrated equivalent treatment.As required by 40
CFR§437.41(b)-(c)and once the facility is permitted to operate as a CWT the permittee will include on-
site data within the Periodic Certification Statements which demonstrate equivalent treatment is being
achieved.
