Section 1. Facility Activities and Process:
ECOFLO, Inc. is a recycling facility that receives and transports various liquid and solid hazardous
waste materials from industry and the household hazardous waste program. The facility performs
solidification, lab-pack/depack consolidation, fuel blending and bulk consolidation processing.
Per an email dated 4/10/2023 from Preston Black(ECOFLO representative), all operation is under roof
but the facility stores empty containers and HHW waste outside that is not under roof. All roof drains do
not go to one outfall, and the loading docks by the south processing and staging area are undercover and
loading is sloped towards the building.
Outfall SWO02:
Drainage area consists of employee parking lots and industrial stormwater flow from SW001 drainage
area.
Outfall SWO03:
Drainage area consists of employee parking lots and industrial stormwater flow from SW001 drainage
area.
Additional outfalls:
Outfall SW001:
Drainage area consists of the non-hazardous solidification process building. Per July 2023 DEMLR
inspection report, outfall has been bermed and no longer discharges. Per phone call 8/25/2023, flow
from SW001 drainage area sheet flows across the property and across the parking lots to discharge from
SWO02 and SW003.

Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."
Section 2. Monitoring Information and Compliance History:
• June 2016 to March 2023,benchmarks exceeded for:
o SW001: Lead Ix, COD Ix,pH min not reached 5x
o SWO02: TSS 3x, BOD 5x, Lead Ix, COD 4x,pH min not reached 4x
o SWO03: pH min not reached 5x
• Per additional information provided 3/31/2023, outfalls SW001, SW002, and SWO03 were in
Tier Response during the previous permit
• Per the April 2023 inspection report, the facility is in Tier 2 for TSS. The exceedance was
attributed to a wood fines bin used to solidify liquids. The inspection report also notes previous
inspections failed to locate outlet 2, but there is a storm drain outside the fence in the back of the
facility. The facility could eliminate this outfall by grading this area to ensure all stormwater
flows to the front of the facility. This area was also lacking sufficient vegetation to restrain
sediment on site and could be a contributing factor to the TSS exceedances. This area should be
stabilized.
• Facility has coverage under NCGNE0653; coverage will be rescinded with renewal of the
individual permit

Threatened/Endangered Species:
There are no threatened or endangered species at the facility location. The facility and nearby vicinity
has species of concern including the Lowland loosestrife (Steironema hybridum; NC status: SR-P),
Greensboro Burrowing Crayfish (Cambarus catagius;NC status: SC), and Yellow-crowned Night-heron
(Nyctanassa violacea; NC status: SR)
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for June 2016 to March 2023. Quantitative sampling included pH, TSS, BOD, COD, and lead.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the ECOFLO, Inc. site.
Outfalls SW001, SW002, and SWO03
Quarterly monitoring
Total Suspended Solids BASIS: Potential pollutant from drainage area and BMP effectiveness
(TSS) indicator.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan(SWPPP).
Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Parameter Benchmark Basis
Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)
Non-Polar Oil & Review of other state's daily maximum benchmark
Grease 15 mg/L concentration for this more targeted O&G;NC WQS that
EPA Method 1664 does not allow oil sheen in waters
SGT-HEM
BOD 30 mg/L BPJ; Based on Secondary Treatment Regulation(40 CFR
133.03
COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic
wastewaters
Lead Total 75 /L Acute Aquatic Criterion, 1/2 FAV
Page 4 of 7

Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier
Three. The Regional Engineer may direct the response actions on the part of the permittee as
provided in Tier Three, including reduced or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.
Section 4. Changes from previous permit to draft:
Page 5 of 7

• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• Feasibility study requirement removed per updated stormwater program requirements
• eDMR requirement added
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Outfall-specific monitoring been implemented to reflect industrial activity and potential
pollutants specific to each discharge area
• Monitoring for total hardness added for all outfalls as monitoring for hardness dependent metals
is required
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
Section 5. Changes from draft to final:
• SW001 removed from permit based on July 2023 inspection report (bermed and no longer
discharges)
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 3/22/2023
• Initial contact with Regional Office: 3/22/2023
• Draft sent to CO peer review: N/A
• Draft sent to Regional Office: 5/18/2023
• Final permit sent for supervisor signature: 8/25/2023
Section 7. Comments received on draft permit:
• Ben Kirby (PWS; via email 5/31/2023): Our Office concurs with the issuance of this permit
provided the facility is operated and maintained properly, the stated effluent limits are met prior
to discharge (if applicable), and the discharge does not contravene the designated water quality
standards.
• Preston Black(permittee; via email 5/22/2023): Please hold off on finalizing the permit. Due to
the recent NPDES inspection, we have a few corrective actions to make beforehand before the
final permit is issued. We are currently trying to eliminate one outfall and have that represented
in the renewal permit.
o DEMLR Response: The draft permit is in the public comment period right now (as it
was already submitted for public notice), however, final review of the permit will be held
until July 1, 2023. Please notify of any schedule changes that may delay implementation
of the corrective actions.
o Preston Black(via email 6/15/2023): An installment will be done to eliminate outfall 1. I
am certain the project will not be completed and reinspected by July 1st, so I am
requesting an extension on the final permit renewal until the end of July. I believe this
will give us enough time for installment and reinspection by DEQ before renewing the
final permit.

• Lily Kay (DEMLR WSRO; 7/6/2023 inspection report): This inspection was conducted to assess
the berm constructed to divert stormwater away from outlet 001. This berm appears sufficient to
prevent the stormwater on site from discharging to outlet 001. It is recommended that this outlet
be removed from the permit.

Brianna,
Attached is the proposal. Due to the rain this entire week, it is hard for him to schedule a date to begin initial
installment. Nevertheless, he did come revisit our site today and which he stated that he would like to have it done
before he goes on vacation the week of July 10th. Weather permitting,we should be able to have it completed by then.
Let me know if you have any questions.

Brianna,
Per our conversation,the map below illustrates the installment that we will proceed with to eliminate outfall 1. 1 am
expected to receive the proposal and schedule date for installment hopefully by the end of tomorrow. I am certain the
project will not be completed and reinspected by July 15Y, so I am requesting an extension on the final permit renewal
until the end of July. I believe this will give us enough time for installment and reinspection by DEQ before renewing the
final permit. In addition, attached is the dimensions as well for your review.
Let me know if you have any questions.
Thanks

We are currently in contact with the contractor to schedule a date and time to address the corrective action. Once
completed, Lilly from NPDES will have to revisit our site to confirm the correction action has been completed. Could you

Please hold off on finalizing the permit. Due to the recent NPDES inspection, we have a few corrective actions to make
beforehand before the final permit is issued. We are currently trying to eliminate one outfall and have that represented
in the renewal permit.

Preston,
Thank you for submitting this information. Based on the site map you provided, I have a few follow-up questions:
• To confirm, do all operations and storage take place under roof(including ASTs and truck loading/unloading
activities)?All operation is under roof but we do store empty containers and HHW waste outside that is not
under roof.
• You stated the non-hazardous solidification process goes to outfall 1. Is this in reference to the section of non-
haz solidification building within the surface water divide identified in the submitted site map? Do all roof drains
go to one outfall? Correct and no all roof drains do not go to one outfall.
• Can you provide more information on the loading docks by the south processing and staging area (is whole area
is under cover, is loading bay sloped towards the building, etc.)?Yes all loading docks are undercover and yes
loading is sloped towards the building.
• Can you please provide the outfall coordinates in either degree-minutes-seconds or decimal degrees?
Thank you,

information is correct and there has been no operational changes.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that

Preston,
Thank you for submitting this information. Based on the site map you provided, I have a few follow-up questions:
• To confirm, do all operations and storage take place under roof(including ASTs and truck loading/unloading
activities)?All operation is under roof but we do store empty containers and HHW waste outside that is not
under roof.
• You stated the non-hazardous solidification process goes to outfall 1. Is this in reference to the section of non-
haz solidification building within the surface water divide identified in the submitted site map? Do all roof drains
go to one outfall? Correct and no all roof drains do not go to one outfall.
• Can you provide more information on the loading docks by the south processing and staging area (is whole area
is under cover, is loading bay sloped towards the building, etc.)?Yes all loading docks are undercover and yes
loading is sloped towards the building.
• Can you please provide the outfall coordinates in either degree-minutes-seconds or decimal degrees?
Thank you,

Good afternoon,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000567.
Please continue to comply with all conditions and monitoring requirements in your current NPDES stormwater
permit. As long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the Division
issues a renewal permit or notifies you of an alternative action.
I am working on renewing the individual stormwater permit for the ECOFLO, Inc. (NCS000567). I need
additional information in order to 1) confirm that the information I have is correct and 2)make sure the permit
adequately serves the needs of the facility. Please provide the following:
• Description of industrial activity occurring onsite; Solidification, lab-pack/depack consolidation, fuel
blending and bulk consolidation processing.
• Confirmation on the number of outfalls and associated coordinates; 3 Outfalls
• Description of industrial activity in each drainage area; No industrial activity near drainage area.
• SIC (NAICS) code; 562211
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit; See attached monitoring data.
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted. Application
information is correct and there has been no operational changes.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s) for the
facility. Please review the facility information to make sure it is correct. Information can be updated using the links
provided below, where applicable:
• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation (Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact
Update Request Form
• Delegation of Signature Authority (DOSA): Permit Contact Update Request Form
• Billing contact: Permit Contact Update Request Form

• Facility address only: Email Georgoulias

• Stormwater outfall information: Email Bethany Geor_og ulias
• Visit the eDMR Six Steps website and complete Steps 1 and 2.
• Pay outstanding permit fees: Stormwater ePayment website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

Best Management Practices
Risk Identification and Summary of Potential Pollution Sources
The major areas of concern identified at the facility that may pose significant risk as potential
storm water pollutant sources include all areas discussed above.
MEASURES AND CONTROLS
This section is designed to identify the currently acknowledged and appropriate "Best
Management Practices" (BMPs) for minimizing storm water pollution. The measurements and
controls listed are adequate to minimize storm water pollution.
Source Area Control
To the maximum extent practicable, and to the extent it is cost effective, the use of source area
control best management practices designed to prevent storm water from becoming
contaminated will be used.
Good Housekeeping
The facility will follow good housekeeping procedures to reduce the possibility of accidental
spills and to minimize safety hazards to facility personnel. These procedures include training,
inspections for situations that could lead to a release, procedures for reporting and cleaning
spills and preventive maintenance.
Preventive Maintenance
Preventive Maintenance involves the regular inspection, testing, and cleaning of facility
equipment and operational systems. These inspections will help to uncover conditions that
might lead to a release of materials. Thus, allowing for maintenance to prevent such a release.
Daily, inspection activities contribute to the facilities continued operations.
