SOURCE INFORMATION
General Description
Standard Gypsum Products (formerly Deseret Laboratories) manufactures vitamins for human
consumption. Vitamin powders are processed into granular material in a fluidized bed granulator by
applying liquid to the powder with a spray nozzle. The materials are then compressed into pills and sent
through a coating machine where an aqueous, colored solution is applied to the surface of each pill. After
the surface coating, the pills are dried and packaged for shipping. Baghouses are used to control the
emissions from the granulating process machines and the dryers.

SOURCE DESCRIPTION

General Description Standard Gypsum Products (formerly Deseret Laboratories) manufactures vitamins for human consumption. Vitamin powders are processed into granular material in a fluidized bed granulator by applying liquid to the powder with a spray nozzle. The materials are then compressed into pills and sent through a coating machine where an aqueous, colored solution is applied to the surface of each pill. After the surface coating, the pills are dried and packaged for shipping. Baghouses
are used to control the emissions from the granulating process machines and the dryers. NSR Classification:

REVIEWER COMMENTS

1. Comment regarding Minor Modification:
This initial NOI for this minor modification noted the addition of one (1) granulator, one (1) vibrating dryer, and one (1) dust collector (baghouse). However, previous compliance inspections note the equipment list was accurate and has been updated as part of this NOI.
The equipment being added to this source are completely enclosed and are vented through
baghouses. The addition of this equipment increases emissions by less than 0.01 tons per year, which is why the changes in tons per year in this document are listed as zero (0). PM2.5 emissions have been equated to PM10 and added to the Summary of Emissions. [Last updated June 8, 2022]
2. Comment regarding NSPS and MACT Applicability: This source is not subject to any NSPS or MACT regulations. [Last updated June 8, 2022]
3. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following:
1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous Air Pollutants. 4. Any Title IV affected source. This source is not a major source, Title IV affected source, or subject to NSPS or MACT regulations. There are no other reasons why this source would be required to obtain a Title V permit; therefore, Title V does not apply to this facility. [Last updated July 21, 2022]

Hello EQ,
Hope this finds you well.
Yes, you are correct in saying that many changes have been made to the baghouses from additions on new dust collectors and redesigned of
existing. I have attached an Excel spreadsheet to show my recalculation of our site emissions.
The two new boilers were added, and the older ones emitted. Operation hours for the Boilers are based on one boiler being on all the time and the
other on only when changing boilers for rotation.
Dust collectors’ hours of operations were based on actual run time hour average for the last 3 months, and then times 12 months for .
The attachment shows the control and the airflow rate along with emission calculations.
In researching I did not find the Emission rate gr/cu.ft for our dust collectors so the 0.016 was used for the calculations.
Please let me know if this looks correct and if there is any other information needed.

General Description:
Manufactures vitamins for human consumption. Vitamin powders are processed into granular material in a fluidized be
granulator by applying liquid to the powder with a spray nozzle. These materials are then compressed into pills and sent
through a coating machine where an aqueous, colored solution is applied to the surface of each pill. After the surface coating,
the pills are dried and packaged for shipping. Baghouses are used to control the emissions for the granulation process
machines and the dryers.

Hello EQ,

I realize with all the additional Baghouses added over the years and some not being active makes this hard to understand
what is different. The two original Boilers the 100 HP Cleaver Brooks and the 75 HP Dixon have been removed and are
out of service.

We have replaced these with the current 150 HP Kewanee boilers with new burners to have clean emissions. These
Boilers are on the New Approval Order that Rita Trick and I were working on.

I have highlighted in RED the original baghouse numbers from the old Approval order. Some Baghouses have been
assigned different numbers but are the same Baghouses in the old Approval Order. We have added Baghouses which are
not on the old Approval Order, the additions are to control emissions better overall. I am reporting every Baghouse on the
property whether active or not. Inactive units will be reported once the intent to activate.

Most of the Baghouses are the same, expect for the new additions.

Old Approval Order Baghouse Numbers to New Assigned Number System due to Locations

Baghouse 1 & 2 is now # 7

Baghouse # 3 is now # 1

Baghouse # 4 is now # 10

Baghouse # 5 is still # 5

Baghouse # 6 is now # 9

Baghouse # 7 is Gone the grinder is not in Service.

I hope this helps in sorting out the Baghouses, Our Current Baghouse #15, #16 and #17 are not currently in service. I
believe #16 maybe the first one in service in 3 month or more.

Application
Polipleet® cartridge media provides more efficient fine-particulate
filtration than conventional felted media. Superior efficiency
results in lower emissions and improves environmental quality
indoors and outdoors.
Effective filtration area is maintained because of the generous
pleat spacing and shallow pleat depth.
Filter elements are compact, saving valuable production space.
Most existing fabric collector housings can be retrofitted to
increase production capacity and to reduce emissions. New
installations benefit from smaller housing sizes.
All materials used in the Polipleet® cartridge have been tested
and passed by an independent laboratory in accordance with
FDA rules for direct dry food contact.
Operating principle
Polipleet® media is 100% polyester spun bound. It is created
by having two different polyester resins continuously sprayed
through miniature nozzles onto a moving web. One of the
resins has a slightly lower melting point. The mat is drawn
through heated rollers that compact and fuse the fibers
together, forming surface patterns into both sides of the media.
The resulting media has the following characteristics:
Strong continuous fibers
Small fiber size
Burst strength similar to felt
Dense, thick mat
Small pore size
Strength in all directions
Thermally stable
Same permeability as needled felt
Polipleet® Pleated Cartridge Filter Media
■High efficiency
■Space savings
■Versatility
■Proven superior performance
www.schenckprocess.com/us • [phone]
Specifications
Standard materials used for Polipleet® are:
polyurethane in the top and bottom caps; polypropylene
inner core, and polyester media. There are no metal
components used in cartridges rated up to temperatures
of 200 °F (93 °C).
On the cartridges rated up to 265 °F (129 °C), the
inner polypropylene core is replaced with a zinc plated
carbon steel perforated tube. The polyurethane top
and bottom are replaced with galvanized steel and
utilize a top of a snap band bag to snap into the
tubesheet which performs the function of sealing the
cartridge to the tubesheet.
For special applications, stainless steel components can
be utilized as well as a variety of filter medias such as
Aramid and PPS.

Schenck Process LLC also expects the emissions of its new 100% Spunbond Polyester Polipleet cartridge
filter, when properly installed, applied and maintained, and when operated per the design parameters
referenced in the original proposal and in accordance with the manufacturers operations manuals, to emit
no more than 0.005 grains/dscf of air based on dry dust particle sizes of 0.5 microns and larger.

The Buyer will be responsible for any emissions testing expense and Schenck Process LLC reserves
the right to be present during any emission tests and shall be notified at least 2 weeks prior to the testing.
Emissions testing must be conducted within 30 days of start-up, or 60 days from equipment shipment.

Hello EQ,
I recently reviewed the most recent inspection memo for Standard Gypsum and see you are working on an AO
modification with the source. I just wanted to make sure you knew they have installed two boilers that are each over 5
MMBtu/hr. The boilers are Kewanee and were manufactured in 1989. One boiler had the burner replaced in 2020 and
the other in 2021. Information provided in 2021 indicates these burners are Power Flame Model NP2-G-520 with a NOx
rating of <9ppm. For reference I have attached some supporting documentation from our compliance files in case the
source has not provided this previously.
Thanks,
Chad

Application
Typically used as a nuisance dust collector for heavy dustloads.
Because the AVS filter offers bottom bag replacement through
side doors, it’s well suited for applications with low headroom.
The AVS can also be fitted with pleated cartridge media to
improve efficiencies. When fitted with cartridges, the unit is
designated as an AVSC.
Equipment
Electronically timed compressed air is released into a row of
filter bags during operation. These pulses dislodge the captured
dust and allow the filter to clean itself without shutting down the
operation. Schenck Process offers this filter in two styles:
with and without a hopper.
Without the hopper (Style II) the filter is ideally suited as a bin
vent filter for storage tanks, work bins and surge hoppers.
With a 60° hopper (Style III) the filter receives dust through a
hopper entry inlet and discharges the collected dust through
an airlock for dust disposal or recycling.

BV-D5117GB
Standard specifications
Unit stressed for 17” W.C. and 180 ºF standard temperature.
AVS Filters can also be customized for higher operating
static pressures to meet specific application requirements.
Carbon steel construction:
Top plenum and baghouse: 12 ga.
Hopper AVS9 and 16: 10 ga.
Hopper AVS25 and larger: 7 ga.
Full welded exterior and skip welded interior
36 bag units and larger have reinforced housing and
tubesheet
Broke lip flange on top plenum, baghouse, and hopper
Hopper discharge flange: 1/4” x 1-1/2” flat bar
Arrangement:
Service door and header @ 3:00
Exhaust @ 9:00
Inlet @ 9:00
(Flanged hopper does allow for rotating hopper relative
to housing on 90º increments)
■ Suited for low headroom applications
■ Side door access to bottom load
filter media
Can be fitted with either bags or
pleated cartridges, depending on
efficiency requirements
