Metallix Refining Site Evaluation for Stormwater Permit Application
RST Engineering, PLLC
Process Description, Metallix Refining
Metallix is a specialty company that recovers and precious metals from various
types of industrial and commercial waste products. Some of the precious metal
is refined to high purity for sale, and some is sold at lower purity to others for
refining and further processing. The precious metals recovered include gold,
silver, palladium, platinum, and rhodium. The sources of the raw materials used
in Metallix's processes are diverse industries manufacturing and/or recycling
materials used by consumers on a daily basis. Examples of the types of
products involved, but by no means a comprehensive list of them, include
automotive, fine china, photography, medical imaging, consumer electronics, and
jewelry.
The raw materials received include dry solids, sludges containing both solid and
liquid fractions, and liquids. These materials are purchased based on the
precious metal content of the material and the seller is paid based on the amount
of precious metal that can be recovered. The different raw materials are
processed through the plant based on their physical and chemical characteristics.
There are many variations possible in the processes used, but the following
characterization is typical:
Solid Materials
Materials such as sludges, film, wiping rags from the manufacture of fine china,
and other solid materials that contain precious metals are processed in high
temperature furnaces in the absence of oxygen. The ash from these furnaces is
sent to milling where it is reduced to a fine powder that may be blended, assayed
and sold. Selected lots may be sent to the Liquids Department where it is
dissolved and the precious metals plated out. Selected materials may also be
melted and formed into ingots, which are sold. The fine dust from this process, a
potential air pollutant, is captured in a high (>99%) efficiency bag filter and is
returned to the process. A liquid scrubber cleans the exhaust gasses in
accordance with the plant's air quality permit.
Liquid Materials
Liquid materials such as spent plating baths from gold or silver plating operations
are processed to recover the traces of precious metals remaining. The may be
plated out, or may be separated chemically by selective precipitation and filtration.
The sludges and filters are processed through the furnaces. Spent liquids are
treated to remove any other metals, such as copper or arsenic that may be
present. The resulting sludge is disposed of as a hazardous waste. If the
residual liquid contains cyanide, it is shipped off site for treatment and disposal.
Residual liquids that are not hazardous wastes and that meet the criteria

established by Greenville Utilities are discharged to the public sewers after
testing and approval.
Raw Material and Intermediate Product Handling
It is very important that the raw materials received are handled properly to insure
that they are processed in the most efficient manner to allow the recovery of the
precious metals they contain. Raw materials are received by truck and are
unloaded at a covered loading dock and are stored inside the building where they
are staged for processing. No raw materials are stored outside or in an
uncovered area where they may be contacted by rainfall.
Intermediate products are also handled totally inside the building with two
possible exceptions. The first exception is the dust from baghouses. The
captured dust contains precious metals and it is returned to the process so that
these metals can be recovered. The handling of the dust, however, creates the
possibility that the some of the dust may be contacted by rainfall. The baghouse
dust is discharged into a closed container underneath the baghouse. Each
container is picked up and moved into the building as it becomes full. It is
possible, however, that during the switching of containers, a small amount of dust
may escape and be discharged to the ground. If this occurs, then it could be
contacted by rainfall and be washed into the stormwater discharge.
The blowdown from the liquid scrubbers that control the emissions from the
furnaces is also captured and is currently returned to the process where it is
evaporated. Normal practice is to store the captured liquid inside the building,
but it has, on rare occasion, been stored outside for short periods of time. This
raises the potential that any residue on the storage container could be washed
off by rainfall and be discharged with the storm water. Future flows of the
scrubber blowdown will increase as the new furnace achieves full operation, so
Metallix is investigating the feasibility of discharging the scrubber blowdown to
Greenville Utilities.
Empty Containers
Empty containers that held raw materials are normally stored inside the building.
On rare occasion, however, some have been stored outside. These containers
are normally clean, but if any residue of the raw material were present, it could
be contacted by rainfall and introduce a pollutant into the stormwater runoff.
Site Description
The Metallix site is located at 251 Industrial Boulevard, Greenville, NC. The site
coordinates are LAT, 35.6461/ LON,-77.3613. The site occupies 14.82 acres, of
which 4.42 acres are covered with roads, parking lots, and buildings. The
impervious percentage is 28.8%. The remainder of the site is a grassy field that
is mowed for appearance and security reasons. The site drains to ditches on the
west and east sides of the site, which then drain to a ditch along the north side of
the site. This drainage ditch system is part of an area -wide ditch system that is

tributary Parker Creek in the Tar River Basin. The grassy area of the site is not
impacted by any industrial activity. A broad drainage swale is located through
the grassy area that collects rainfall runoff and conveys it to the north property
line. Since this drains an area not impacted by industrial activity, and since it is a
grassed drainage feature, it is not being listed as a stormwater outfall point. All
of the stormwater that may be impacted by industrial activity discharges to the
drainage ditch along the east side of the property. The paved areas and roof
surface areas are drained to drop inlets, which in turn discharge to the drainage
ditch. The point where this ditch leaves the property at the northeast corner is
being considered the stormwater outfall point. Since all of the potentially
impacted stormwater discharges through this point, it is the only outfall point
listed (Outfall 1). A copy of the property map from the Pitt County Register of
Deeds office, with the new stack and building extension added for modeling
purposes for the air quality permit, is attached for reference.
Evaluation for Non -Storm Discharges
During a site visit on September 18, 2014, a careful inspection of all the sources
of wastewater on the site was conducted. None of these sources discharge to
the ground or to any drainage system that can discharge to the stormwater
collection and discharge system. The exterior of the buildings were inspected
and no storage of raw materials, finished products, intermediate products, or
wastes was noted. One potential source of a non -storm discharge was noted
and investigated. This was a condensate trap on the exterior of the main building.
Some steam condensate occasionally dripped from the steam vent pipe onto the
ground. There was, however, no runoff from that point to the drainage ditch as
all of the water was soaking into the ground. Also, there was no channel from
that point to the ditch, which would have indicated that discharges routinely occur.
Based on these observations, it was concluded that there was no non -storm
discharge to Outfall 1.
There are no vehicle maintenance operations conducted on site that could result
in the discharge of pollutants to the stormwater drainage system.,
Tables 1 and 2 below list parameters that are either known or expected to be on
the site (Table 1), or have been detected in samples from process solutions on
the site (Table 2). Many of these parameters are naturally occurring and are
expected to be present in the runoff from the site naturally. The tables attempt to
identify these materials. Metallix does not expect many of the materials detected
in the process liquid analysis to ever be detected in runoff from the site because
of the lack of potential exposure to rainfall. Note also that this list should not be
considered complete. Other materials may be detected on later samples
because different scrap sources may be used. Likewise, many of the parameters
listed may not be detected on later samples for the same reason.

but it has, on rare occasion, been stored outside for short periods of time. This
raises the potential that any regWUe oasbP storage container could be washed
off by rainfall and be discharged with the storm water. Future flows of the
scrubber blowdown will increase as the new furnace achieves full operation, so
Metallix is investigating the feasibility of discharging the scrubber blowdown to
Greenville Utilities.
Empty Containers
Empty containers that held raw materials are normally stored inside the building.
On rare occasion, however, some have been stored outside. These containers
are normally clean, but if any residue of the raw material were present, it could
be contacted by rainfall and introduce a pollutant into the stormwater runoff.
Site Description
The Metallix site is located at 251 Industrial Boulevard, Greenville, NC. The site
coordinates are LAT, 35.6461/ LON,-77.3613. The site occupies 14.82 acres, of
which 4.42 acres are covered with roads, parking lots, and buildings. The
impervious percentage is 28.8%. The remainder of the site is a grassy field that
is mowed for appearance and security reasons. The site drains to ditches on the
west and east sides of the site, which then drain to a ditch along the north side of
the site. This drainage ditch system is part of an area -wide ditch system that is

tributary Parker Creek in the Tar River Basin. The grassy area of the site is not
impacted by any industrial activity. A broad drainage Swale is located through
the grassy area that collects rainfall runoff and conveys it to the north property
line. Since this drains an area not impacted by industrial activity, and since it is a
grassed drainage feature, it is not being listed as a stormwater outfall point. All
of the stormwater that may be impacted by industrial activity discharges to the
drainage ditch along the east side of the property. The paved areas and roof
surface areas are drained to drop inlets, which in turn discharge to the drainage
ditch. The point where this ditch leaves the property at the northeast corner is
being considered the stormwater ouffall point. Since all of the potentially
impacted stormwater discharges through this point, it is the only ouffall point
listed (Outfall 1). A copy of the property map from the Pitt County Register of
Deeds office, with the new stack and building extension added for modeling
purposes for the air quality permit, is attached for reference.
Evaluation for Non -Storm Discharges
During a site visit on September 18, 2014, a careful inspection of all the sources
of wastewater on the site was conducted. None of these sources discharge to
the ground or to any drainage system that can discharge to the stormwater
collection and discharge system. The exterior of the buildings were inspected
and no storage of raw materials, finished products, intermediate products, or
wastes was noted. One potential source of a non -storm discharge was noted
and investigated. This was a condensate trap on the exterior of the main building.
Some steam condensate occasionally dripped from the steam vent pipe onto the
ground. There was, however, no runoff from that point to the drainage ditch as
all of the water was soaking into the ground. Also, there was no channel from
that point to the ditch, which would have indicated that discharges routinely occur.
Based on these observations, it was concluded that there was no non -storm
discharge to Outfall 1.
There are no vehicle maintenance operations conducted on site that could result
in the discharge of pollutants to the stormwater drainage system.
Tables 1 and 2 below list parameters that are either known or expected to be on
the site (Table 1), or have been detected in samples from process solutions on
the site (Table 2). Many of these parameters are naturally occurring and are
expected to be present in the runoff from the site naturally. The tables attempt to
identify these materials. Metallix does not expect many of the materials detected
in the process liquid analysis to ever be detected in runoff from the site because
of the lack of potential exposure to rainfall. Note also that this list should not be
considered complete. Other materials may be detected on later samples
because different scrap sources may be used. Likewise, many of the parameters
listed may not be detected on later samples for the same reason.

Mr. Bulow,
Thank you for calling me yesterday in response to my email. Since the application for an individual permit was
submitted, the company should continue with that process, but currently the submittal is incomplete. Because the plant
has been in operation, the application requires that a storm water sample be taken and "the results of at least one
analysis for every pollutant" be shown in Table VII Part A. Below is a list of the missing items needed in order to
complete the application and move forward in the application process.
1. Section V is missing a signature and date.
2. Section VII Part A is missing analysis for pollutants listed for each outfall.
3. "Sampling results for pollutants that you know or have reason to believe is present" is missing from table C.
I have enclosed a copy of the pages with the missing items. The results from the storm water samples will enable us to
craft an appropriate permit for the site.
Let me know if you have any questions.
Thanks

3.0 What is the Definition of No Exposure?
No exposure means all industrial materials and activities are protected by a storm
resistant shelter to prevent exposure to rain, snow, snowmelt and/or runoff.
Industrial materials and activities include, but are not limited to, material handling
equipment or activities; industrial machinery; raw materials, intermediate products, by-products,
and final products; or waste products.
Material handling activities include storage, loading and unloading, transportation or
conveyance, of any raw material, intermediate product, by-product, final product or waste
product.
Many final products which are meant to be used outdoors (e.g., automobiles) pose little
risk of storm water contamination, i.e., the products cannot be mobilized by precipitation or
runoff, and are thus exempt from the requirement that these products be sheltered to qualify for
no exposure. Similarly, the containers, racks and other transport platforms (e.g., wooden pallets)
used for the storage or conveyance of these final products can also be stored outside, providing
the containers, racks and platforms are pollutant -free.
Storm -resistant shelters include completely roofed and walled buildings or structures, as
well as structures with only a top cover but no side coverings, provided material under the
structure is not otherwise subject to any run-on and subsequent runoff of storm water.
EPA acknowledges there are circumstances where permanent, uninterrupted sheltering of
industrial activities or materials is not possible. Under such conditions:
Materials and activities may be sheltered with temporary covers (e.g., tarpaulins) until
permanent enclosure can be achieved.
The no exposure provision does not specify every such situation, but NPDES permitting
authorities can address this issue on a case -by -case basis, i.e., determine if the temporary
covers will meet the requirements of this section.
In general, EPA recommends that temporary sheltering of industrial materials and
activities only be allowed during facility renovation or construction.
3.1 Industrial Materials / Activities That Do Not Require a Storm Resistant Shelter
While the intent of the no exposure exclusion is to promote a condition of permanent no
exposure, a storm -resistant shelter is not required for the following industrial materials and
activities:

3.1.1 Drums, Barrels. Tanks and Similar Containers. Drums, barrels, tanks and similar
containers that are sealed ("sealed" means banded or otherwise secured and without operational
taps or valves), are not exposed provided those containers are not deteriorated and do not leak.
Unless the drums, barrels, etc., are opened while outdoors, or are deteriorated or leak, they will
likely not constitute a risk of contaminating storm water runoff. Consider the following in
making your no exposure determination:
Containers can only be stored outdoors; any addition or withdrawal of material to / from
containers while outdoors will not allow you to certify no exposure.
Simply moving containers while outside does not create exposure.
Inspect all outdoor containers to ensure they are not open, deteriorated or leaking.
EPA recommends that a designated individual regularly conduct these
inspections.
Any time external containers are open, deteriorated or leaking, they must
immediately be closed, replaced or sheltered.
Containers, racks and other transport platforms (e.g.,wooden pallets) used with the
drums, barrels, etc., can be stored outside providing they are contaminant -free.
3.1.2 Above Ground Storage Tanks (ASTs). In addition to generally being considered not
exposed, ASTs may also be exempt from the prohibition against adding or withdrawing material
to / from external containers. ASTs typically utilize transfer valves to dispense materials which
support facility operations (e.g., heating oil, propane, butane, chemical feedstocks) or fuel for
delivery vehicles (gasoline, diesel, compressed natural gas). For ASTs to be operational and
qualify for no exposure:
They must be physically separated from and not associated with vehicle maintenance
operations.
There must be no piping, pumps or other equipment leaking contaminants that could
contact storm water.
EPA recommends, wherever feasible, that ASTs be surrounded by some type of physical
containment (e.g., an impervious dike, berm or concrete retaining structure) to prevent
runoff in the event of a structural failure or leaking transfer valve. Note: any resulting
unpermitted discharge would violate the CWA.
3.1.3 Lidded Dumpsters. Lidded dumpsters containing waste materials, providing the
containers are completely covered and nothing can drain out holes in the bottom, or is lost in

Pat,
There is an existing No Exposure permittee that might or might not still be eligible for coverage under their current
permit. Their engineer, Stan Taylor, thinks that they need an individual permit and submitted an application. I am not
so sure that they no longer qualify as "no exposure".

If you could have inspector check site and see if:
1. The No Exposure site is fine with no changes.
2. The No Exposure site has a minor issue and with an easy change the permittee could continue under their No
Exposure permit.
3. Conditions have changed and the permittee no longer qualifies as No Exposure and needs an individual permit.
Also, Stan would like to be present during the inspection, if possible. His number is 919-271-4465.
If you could let me know of the determination so I can either let them keep their No Exposure permit or move forward
with the application for individual permit.

The Division has reviewed your submittal of the No Exposure Certification
for Exclusion from NPDES Storm Water Permitting form, which we
received July 9, 2003. Based on our review, the Division has determined
that the facility qualifies for the conditional no exposure exclusion provided
for under 40 CFR 126.22(g) which is incorporated by reference in North
Carolina regulations.
Please note that by our acceptance of your no exposure certification, you are
obligated to maintain no exposure conditions at your facility. If conditions
change such that your facility can no longer qualify for a no exposure
exclusion, you are obligated to immediately obtain NPDES permit coverage
for your stormwater discharge. Otherwise, the discharge becomes subject
to enforcement as an un-permitted discharge.
Your conditional no exposure exclusion expires in five years. At that time
you must re -certify with the Division, or obtain NPDES permit coverage for
any stormwater discharges from your facility.
Your certification of no exposure does not affect your facility's legal
requirements to obtain environmental permits that may be required under
other federal, state, or local regulations or ordinances.

NPDES Storm Water Permitting
Submission of this No Exposure Certification constitutes notice that the entity identified in Section A does not require permit authorization for its storm water
discharges associated with industrial activity in the Stale identified in Section B under EPA's Storm Water Multi -Sector General Permit due to the existence
of a condition of no exposure.
A condition of no exposure exists at an industrial facility when all industrial materials and activities are protected by a storm resistant shelter to prevent
exposure to rain, snow, snowmell, and/or runoff. Industrial materials or activities include, but are not limited to, material handling equipment or activities,
industrial machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage,
loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product. A storm resistant shelter is
not required for the following industrial materials and activities:
- drums, barrols, tanks, and similar containers that are tightly scaled, provided those containers are not deteriorated and do not leak. "Sealed"
means banded or otherwise secured and without operational taps or valves,
- adequately maintained vehicles used in material handling: and
- final products, other than products that would be mobilized in storm water discharges (e.g., rock salt),
A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In addition, the exclusion from NPDES permitting !s
available on a facility -wide basis only, not for individual curtails. If any industrial activities or materials are or will be exposed to precipitation, the facility is
not eligible for the no exposure exclusion.
By signing and submitting this No Exposure Certification form, the entity in Section A is certifying that a condition of no exposure exists at its facility or site,
and is obligated to comply with the terms and conditions of 40 CFR 122.26(g).
