Section 1. Facility Activities and Process:
Carus, LLC produces various phosphates sold primarily to municipal water systems for drinking water
corrosion control. The facility blends/mixes various materials to formula required by each client,
wastewater treatment system, etc. and then packages the materials into sacks, totes, or tanker load. Oils
and chemicals are stored inside the manufacturing building. Oils stored at the site include compressor
oil, hydraulic oil, etc. Chemicals stored at the site include sacks of powders (phosphates, zinc oxide, and
zinc sulfate), totes, and numerous 500 to 6,000 gallon aboveground storage tanks (ASTs) of liquids
(phosphate materials, phosphoric acid, sodium hydroxide, zinc chloride, zinc oxide, and zinc sulfate).
Tanker trucks with a sodium hydroxide/zinc sulfate solution unload from outside to inside the building.
Per notes in the permit file history, the cooling tower water uses reclaimed water that's been sent
through filtration and RO permeate used for process (clean) concentrate steam and is used to cool. All
stormwater drains to a concrete -lined stormwater retention basin, where it is allowed to evaporate and
discharge (although overflows are possible).
Outfall SW001:
Drainage area contains a concrete stormwater retention basin, manufacturing building, parking areas,
tank parking area, cooling tower, tanker truck loading/unloading area, loading dock, underground
sumps/holding tanks, transformer, back-up generator, tote storage, and dumpsters.
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
Page 1 of 6

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:
• January 2012 to April 2O22, benchmarks exceeded for:
o pH min not reached 2x
o TSS 2x
o Total phosphorus 14x
o Zinc 17x

Threatened/Endangered Species:
There are no threatened/endangered species at the point of discharge, however, in the nearby vicinity
there are the Georgia Aster (Symphyotrichum georgianum; NC status: T; Federal status: C), Bush's
Sedge (Carex bushii; NC status: SR-P), Villosa delumbis (Eastern Creekshell; NC status: SR), and
Eastern Pondmussel (Ligumia nasuta; NC status: T).
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for January 2012 to April 2022. Quantitative sampling included pH, TSS, total hardness, total
phosphorus, and zinc.
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 Carus, LLC 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.
Page 3 of 6

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:

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
Page 4 of 6

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. Chanp_es from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• eDMR requirement added
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
• Monitoring for COD added based on chemicals stored onsite

include sacks of powders (phosphates, zinc oxide, and zinc sulfate) and totes and numerous 500 to 6,000-gallon
aboveground storage tanks (ASTs) of liquids (phosphate materials, phosphoric acid, sodium hydroxide, zinc chloride, zinc
oxide, and zinc sulfate). The dry raw materials are stored in the western portion of the manufacturing building. The
ASTs and liquid chemicals are located in the eastern portion of the building. see attached figure. Several ASTs
containing water, sodium hydroxide, and a mixture of sodium hydroxide and zinc sulfate are stored in the compressor
room. Tanker trucks with a sodium hydroxide / zinc sulfate solution unload outside the east side of the building into the
ASTs inside the compressor room. The facility blends / mixes various materials to formula required by each client /
wastewater treatment system / etc and then package the materials into sacks, totes, or tanker load.
4. Stormwater monitoring data to date is summarized in the attached table. Samples are also collected from the
driveway entering the site and other areas of the facility (i.e., roof gutters, tap water) to show that the stormwater

Notes.

Carus Corporation
181 Woodlawn Street, Belmont, Gaston County, NC
Permit #NCS000543
Several best management practices (BMPs) are currently in place at the facility to reduce the
exposure of stormwater to industrial activities. These BMPs are as follows:
- Containers of chemicals and oils are stored inside the building on concrete floors away
from doorways.
- Roofs / canopies are located over the loading / unloading areas / loading docks.
- Tanker trucks load/unload at two loading docks / areas. Drip containment troughs are
attached to the walls at the hose connections in the eastern and southern loading areas.
- A concrete containment area (pad and bermed area with ramp) is present at the
unloading/ loading area outside the southern portion of the manufacturing building. The
containment area is sloped towards the building. A trench drain is located along the
loading docks. The drain leads to two underground concrete sumps/pits outside the
southeast corner of the building. These sumps can be used to hold a spill and/or direct
the runoff to sanitary sewer or to the onsite stormwater retention basin.
- All totes/drums are emptied and lids/bungs placed on the container before placement
outside. Containers outside the building are located on asphalt. A stormwater drain /
catch basin is located in the vicinity of the dumpsters / tote storage areas. The drain leads
to a concrete lined stormwater retention basin.
- All stormwater on the site drains to a concrete -lined stormwater retention basin.
Rainwater is allowed to evaporate in the basin. Overflow occurs from the basin when
levels reach a certain level.
- No vehicle maintenance is performed on site.
- No vehicle washing is performed in the driveways and parking areas.
- Solid waste and materials to be recycled are placed in dumpsters that are located on
concrete pads or asphalt. No oils or chemicals are placed in the dumpsters. The
dumpsters are kept closed.

SUPPLEMENTAL INFORMATION REQUIRED FOR RENEWAL OF INDIVIDUAL
NPDES STORMWATER PERMIT
Two copies of each of the following shall accompany this submittal in order for the application
to be considered complete:
Initials

1. A current Site Map from the Stormwater Pollution Prevention Plan. The location of
industrial activities (including storage of materials, disposal areas, process areas and
loading and unloading areas), drainage structures, drainage areas for each outfall,
building locations and impervious surfaces should be clearly noted.
2. A summary of Analytical Monitoring results during the term of the existing permit
(if your permit required analytical sampling). Do not submit individual lab reports.
The summary can consist of a table including such items as outfall number,
parameters sampled, lab results, date sampled, and storm event data.
3. A summary of the Visual Monitoring results. Do not submit individual monitoring
reports. The summary can consist of a table including such items as outfall number,
parameters surveyed, observations, and date monitoring conducted.
4. A summary of the Best Management Practices utilized at the permitted facility.

Carus Corporation
181 Woodlawn Street, Belmont, Gaston County, NC
Permit #NCS000543
Several best management practices (BMPs) are currently in place at the facility to reduce the
exposure of stormwater to industrial activities. These BMPs are as follows:
- Containers of chemicals and oils are stored inside the building on concrete floors away
from doorways.
- Roofs / canopies are located over the loading / unloading areas / loading docks.
- Tanker trucks load/unload at two loading docks / areas. Drip containment troughs are
attached to the walls at the hose connections in the eastern and southern loading areas.
- A concrete containment area (pad and bermed area with ramp) is present at the
unloading/ loading area outside the southern portion of the manufacturing building. The
containment area is sloped towards the building. A trench drain is located along the
loading docks. The drain leads to two underground concrete sumps/pits outside the
southeast corner of the building. These sumps can be used to hold a spill and/or direct
the runoff to sanitary sewer or to the onsite stormwater retention basin.
- All totes/drums are emptied and lids/bungs placed on the container before placement
outside. Containers outside the building are located on asphalt. A stormwater drain /
catch basin is located in the vicinity of the dumpsters / tote storage areas. The drain leads
to a concrete lined stormwater retention basin.
All stormwater on the site drains to a concrete -lined stormwater retention basin.
Rainwater is allowed, to evaporate in the basin. Overflow occurs from the basin when
levels reach a certain level.
- No vehicle maintenance is performed on site.
- No vehicle washing is performed in the driveways and parking areas.
- Solid waste and materials to be recycled are placed in dumpsters that are located on
concrete pads or asphalt. No oils or chemicals are placed in the dumpsters. The
dumpsters are kept closed.
