Section 1. Facility Activities and Process:
AERC Acquisitions Corporation dba Dart A Clean Earth Company is a hazardous waste management
facility that provides hazardous and non-hazardous waste management. Activities that occur at the
facility include: Brokering of hazardous and non-hazardous waste to third parties for treatment, storage,
and disposal facilities, storage of hazardous and non-hazardous waste in containers, storage of hazardous
waste in tank systems, fuel blending and storage in tanks of organic materials acceptable for combustion
in incinerators or boilers and industrial furnaces, loading and unloading of waste materials from trucks
and railcars, consolidating hazardous and non-hazardous wastes into larger containers, wastewater
treatment of hazardous and non-hazardous waste, incidental de-packing and repacking of laboratory
chemicals, transfer facility for used oil, storage and treatment of non-hazardous industrial, commercial
liquid and solid wastes, consumer product destruction and recycling. Empty totes that once contained
hazardous waste are kept on site and are washed free of any residue, and wash water is collected and
treated in the pretreatment system that discharges to the Charlotte POTW.
Per the last permit fact sheet: Most of their activities are inside with loading and unloading that is
exposed but areas are contained and materials collected and go to treatment. Detention pond captures all
site runoff and is released within 24 hrs after a rain event. If there is a large storm it could overflow or
they may release during the storm.
Per an email dated 5/22/2018 from Mecklenburg County Stormwater: The pond is a concrete lined basin
that is equipped with a manually activated gate valve, and the valve remains closed except during a
planned discharge. The BOD value of 13.6 is not necessarily an issue or that it necessitates the addition
of a BOD parameter. The source of copper at this site is likely from heavy trucks for material delivery
more so than site materials/processing exposure.

Outfall SW001:
Drainage area consists of empty drums,pallets, and totes that previously contained hazardous waste, and
a stormwater retention basin.
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:
• March 2019 to May 2023,benchmarks exceeded for:
o COD Ix
Threatened/Endangered Species:
The Tall Larkspur(Delphinium exaltatum; NC status: T) is a threatened species in the vicinity of the
facility.
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for March 2019 to May 2023. Quantitative sampling included pH, TSS, and COD.
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 Clean Earth Company facility site.

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
Page 3 of 5

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
COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic
wastewaters
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-
Page 4 of 5

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:
• Regulatory citations added
• 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
• Annual online SWPPP certification requirement removed per updated stormwater program
requirements
• eDMR requirement updated
• 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
Section 5. Changes from draft to final:
• None
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 12/12/2023
• Initial contact with Regional Office: 12/12/2023
• Draft sent to CO peer review: N/A
• Draft sent to Regional Office: 3/13/2024

Inspection Summary:
Kathryn Peterson and Jerry Eplin inspected DART Acquisitions(Clean Earth)on February 22, 2024 at 12:35 PM to 1:30 PM.
This inspection was conducted as part of the permit renewal process. Site was found to be in compliance.The SWPPP was
missing documentation of the annual review that was supposed to occur in 2023. Mr. Dilworth, EHS site manager, believed
that the request for a new permit application was considered an annual review of the SWPPP, and consdiered the site in
compliance. Mr. Dilworth will send evidence of an annual SWPPP update within one week of inspection to the Mooresville
Regional Office. All other permit requirements were found to be in compliance at the time of inspection. The facility will be
noted as in compliance in the inspection report.

7.5 MINUTE SERIES(TOPOGRAPHIC) JOB NO: CNE-001 APPENDIX: B

6.2 Non-Structural Controls
6.2.1 Grass
Clean Earth has established grass in most areas of the facility to prevent sediment run-off from
the facility operations including areas that are not developed or part of the industrial activity at
the facility.
6.3 Best Management Practices
The sections below summarize the Best Management Practices(BMPs)utilized by the facility to reduce
the potential for potential sources to contribute significant quantities of pollutants to storm water
discharges.This BMP Summary shall be included within the annual review of the SWP3 and updated
as needed.
6.3.1 Good Housekeeping
Good housekeeping practices along with extensive engineered structures are designed to reduce
pollutant contact with storm water through the proper maintenance of material storage and in
loading/unloading areas. Clean Earth maintains good housekeeping practices at the site to
reduce the potential for pollutant loading in the storm water. These practices include periodic
inspection and maintenance of the facility structures and transportation equipment present at
the facility.
Clean Earth employees are to be present during all loading and unloading of waste materials to
ensure that facility practices are followed and to properly respond in the event of a release of
materials prior to contacting storm water.
6.3.2 Preventative Maintenance
Preventative maintenance involves periodic inspection and testing of facility equipment
(including transportation equipment in general conformance with DOT requirements) and
operational systems. Clean Earth conducts periodic inspections of facility structural and non-
structural control measures at the facility that are designed to prevent significant pollutants
from entering the storm water discharge. Specific preventative maintenance activities
associated with storm water management systems are further described in Section 8.0.
21

6.3.3 Visual Inspections
Visual inspections are designed to be a routine examination of the facility to identify the
conditions that may give rise to pollutant(s) entering the storm water discharge. These
inspections review maintenance practices, areas subject to SPCC, as well as inspections of
storm water runoff structures. Periodic inspections are performed at the facility and are further
described in Section 8.0.
6.3.4 Waste Material Management
Waste materials are typically present at the facility and managed in accordance with the
facility's Resource Conservation and Recovery Act operating permit.These materials are either
stored in DOT shipping containers or in permitted facility structures designed and constructed
for the management of hazardous waste. A summary of stored materials and the associated
control measures can be found in table 5-1 on page 19 of this document.
The following management practices minimize the potential for contact between waste
materials and storm water.
• Waste materials in non-bulk packaging are stored inside facility buildings or van
trailers.Containers in non-bulk packaging are DOT specification containers for all
hazardous materials.
• Bulk containers that are present whether empty or full are normally tarped or closed
to prevent contact of waste materials with storm water.
• Loading and unloading of waste materials occurs on loading docks, in areas
designed to capture spills with blind sumps, are unloaded inside buildings, or are
unloaded following procedures to prevent spills or releases from entering storm
water sewer systems.
• The facility has extensive inventory management,training practices,and operating
procedures established to manage waste materials in accordance with the Resource
Conservation and Recovery Act requirements. These practices minimize the
contribution of pollutants to storm water.
6.3.5 Employee Education
Employee education is essential for effective implementation of the SWP3. Employee
education at the facility depends on the type of employee and the duties that are being
22

performed.Topics for employee education include hazardous waste management practices and
procedures, SPCC measures, facility contingency plan, OSHA HAZWOPER, equipment
operation,and related environmental or safety training activities.Facility personnel responsible
for conducting the initial and annual refresher training include the facility Plant Manager,EHS
Manager,and/or the Operations Supervisor.All training geared toward the SWP3 conducted at
the facility, regardless of the frequency is documented by the signature of each employee
trained.
Employee education with respect to this SWP3 will consist of the following activities:
• Initial education for employees that have a direct impact on the storm water
discharge concerning the existence of this SWP3 and concepts associated with the
implementation of the SWP3 for all full-time employees working daily at the
facility during implementation of the plan. It is not necessary for administrative
personnel to participate in training since administrative personnel would not have
potential for impacting storm water.
• Update or refresher education will be performed for all employees, including new
employees that are hired during the time since the prior training session and no less
than annually concerning practices described in the SWP3. Training may also be
performed after an environmental incident involving storm water, after material
changes are made to the SWP3 concerning storm water pollution prevention, or
when new management practices are introduced that are associated with storm
water pollution prevention.
6.4 Storm Water Treatment
In the unlikely event that the storm water should become contaminated Clean Earth can remove the
material via a portable pump and hose. Any storm water accumulated from the holding basin can be
processed it through Clean Earth's on-site wastewater treatment system. This water then would be
discharge into the sanitary sewer under permit from the local POTW.
6.5 Disposal of Solid or Fluid Wastes in Structural Control Measures
Storm water from the facility that has accumulated within the secondary containment areas, is only
discharged after a thorough visually inspection and documented in the facility's rain event discharge
log(Appendix G).Accumulated debris such as leaves,sticks,sediment,etc.are kept to a minimum and

6.2 Non-Structural Controls
6.2.1 Grass
Clean Earth has established grass in most areas of the facility to prevent sediment run-off from
the facility operations including areas that are not developed or part of the industrial activity at
the facility.
6.3 Best Management Practices
The sections below summarize the Best Management Practices(BMPs)utilized by the facility to reduce
the potential for potential sources to contribute significant quantities of pollutants to storm water
discharges.This BMP Summary shall be included within the annual review of the SWP3 and updated
as needed.
6.3.1 Good Housekeeping
Good housekeeping practices along with extensive engineered structures are designed to reduce
pollutant contact with storm water through the proper maintenance of material storage and in
loading/unloading areas. Clean Earth maintains good housekeeping practices at the site to
reduce the potential for pollutant loading in the storm water. These practices include periodic
inspection and maintenance of the facility structures and transportation equipment present at
the facility.
Clean Earth employees are to be present during all loading and unloading of waste materials to
ensure that facility practices are followed and to properly respond in the event of a release of
materials prior to contacting storm water.
6.3.2 Preventative Maintenance
Preventative maintenance involves periodic inspection and testing of facility equipment
(including transportation equipment in general conformance with DOT requirements) and
operational systems. Clean Earth conducts periodic inspections of facility structural and non-
structural control measures at the facility that are designed to prevent significant pollutants
from entering the storm water discharge. Specific preventative maintenance activities
associated with storm water management systems are further described in Section 8.0.

performed.Topics for employee education include hazardous waste management practices and
procedures, SPCC measures, facility contingency plan, OSHA HAZWOPEF, equipment
operation,and related environmental or safety training activities.Facility personnel responsible
for conducting the initial and annual refresher training include the facility Plant Manager,EHS
Manager,and/or the Operations Supervisor.All training geared toward the SWP3 conducted at
the facility, regardless of the frequency is documented by the signature of each employee
trained.
Employee education with respect to this SWP3 will consist of the following activities:
o Initial education for employees that have a direct impact on the storm water
discharge concerning the existence of this SWP3 and concepts associated with the
implementation of the SWP3 for all full-time employees working daily at the
facility during implementation of the plan. It is not necessary for administrative
personnel to participate in training since administrative personnel would not have
potential for impacting storm water.
o Update or refresher education will be performed for all employees, including new
employees that are hired during the time since the prior training session and no less
than annually concerning practices described in the SWP3. Training may also be
performed after an environmental incident involving storm water, after material
changes are made to the SWP3 concerning storm water pollution prevention, or
when new management practices are introduced that are associated with storm
water pollution prevention.
6.4 Storm Water Treatment
In the unlikely event that the storm water should become contaminated Clean Earth can remove the
material via a portable pump and hose. Any storm water accumulated from the holding basin can be
processed it through Clean Earth's on-site wastewater treatment system. This water then would be
discharge into the sanitary sewer under permit from the local POTW.
6.5 Disposal of Solid or Fluid Wastes in Structural Control Measures
Storm water from the facility that has accumulated within the secondary containment areas, is only
discharged after a thorough visually inspection and documented in the facility's rain event discharge
log(Appendix G).Accumulated debris such as leaves,sticks,sediment,etc.are kept to a minimum and

6.2 Non-Structural Controls
6.2.1 Grass
Clean Earth has established grass in most areas of the facility to prevent sediment run-off from
the facility operations including areas that are not developed or part of the industrial activity at
the facility.
6.3 Best Management Practices
The sections below summarize the Best Management Practices(BMPs)utilized by the facility to reduce
the potential for potential sources to contribute significant quantities of pollutants to storm water
discharges.This BMP Summary shall be included within the annual review of the SWP3 and updated
as needed.
6.3.1 Good Housekeeping
Good housekeeping practices along with extensive engineered structures are designed to reduce
pollutant contact with storm water through the proper maintenance of material storage and in
loading/unloading areas. Clean Earth maintains good housekeeping practices at the site to
reduce the potential for pollutant loading in the storm water. These practices include periodic
inspection and maintenance of the facility structures and transportation equipment present at
the facility.
Clean Earth employees are to be present during all loading and unloading of waste materials to
ensure that facility practices are followed and to properly respond in the event of a release of
materials prior to contacting storm water.
6.3.2 Preventative Maintenance
Preventative maintenance involves periodic inspection and testing of facility equipment
(including transportation equipment in general conformance with DOT requirements) and
operational systems. Clean Earth conducts periodic inspections of facility structural and non-
structural control measures at the facility that are designed to prevent significant pollutants
from entering the storm water discharge. Specific preventative maintenance activities
associated with storm water management systems are further described in Section 8.0.

performed.Topics for employee education include hazardous waste management practices and
procedures, SPCC measures, facility contingency plan, OSHA HAZWOPER, equipment
operation,and related environmental or safety training activities.Facility personnel responsible
for conducting the initial and annual refresher training include the facility Plant Manager,EHS
Manager,and/or the Operations Supervisor.All training geared toward the SWP3 conducted at
the facility, regardless of the frequency is documented by the signature of each employee
trained.
Employee education with respect to this SWP3 will consist of the following activities:
e Initial education for employees that have a direct impact on the storm water
discharge concerning the existence of this SWP3 and concepts associated with the
implementation of the SWP3 for all full-time employees working daily at the
facility during implementation of the plan. It is not necessary for administrative
personnel to participate in training since administrative personnel would not have
potential for impacting storm water.
o Update or refresher education will be performed for all employees, including new
employees that are hired during the time since the prior training session and no less
than annually concerning practices described in the SWP3. Training may also be
performed after an environmental incident involving storm water, after material
changes are made to the SWP3 concerning storm water pollution prevention, or
when new management practices are introduced that are associated with storm
water pollution prevention.
6.4 Storm Water Treatment
In the unlikely event that the storm water should become contaminated Clean Earth can remove the
material via a portable pump and hose. Any storm water accumulated from the holding basin can be
processed it through Clean Earth's on-site wastewater treatment system. This water then would be
discharge into the sanitary sewer under permit from the local POTW.
6.5 Disposal of Solid or Fluid Wastes in Structural Control Measures
Storm water from the facility that has accumulated within the secondary containment areas, is only
discharged after a thorough visually inspection and documented in the facility's rain event discharge
log(Appendix G).Accumulated debris such as leaves,sticks,sediment,etc.are kept to a minimum and
