5. SPECTRO ALLOYS CORPORATION SITE PLAN REVIEW
13220 Doyle Path
PROPOSAL
Mr. Jack Lewison of Spectro Alloys Corp. is requesting site plan approval to construct a two
story addition to the plant in the General Industrial (IG) District. Spectro Alloys Corp.
occupies fifteen acres north of State Highway 55 at the end of Doyle Path. The company
recycles aluminum by melting scrap into ingots.
In addition, Spectro Alloys Corp. intends to upgrade existing hazardous materials storage
facilities to respond to issues raised by the City Fire Marshall.
DISCUSSION
Planning Staff toured the site with the Fire Marshall in an effort to address the hazardous
materials storage and identified several ordinance violations in the process. Specifically,
Those violations include:
1) outdoor storage of trash and junk associated with the recycling operations going beyond
what would be allowed in the General Industrial District that permits outdoor storage as
well as other debris scattered about the site;
2) a general lack of turf and paving resulting in potential erosion and contaminated
stormwater runoff problems; and
3) semi trailer parking within the public right -of -way of the Doyle Path cul -de -sac
turnaround in addition to an apparent overall lack of trailer parking organization that
could inhibit emergency response.
Planning Staff would encourage the Planning Commission to visit the site.
The proposed building addition will consist of two stories of approximately 460 sq. ft. per
level and will be attached to building #2. The addition will primarily house an electrical
motor control room for the large blowers that are part of the pollution control system. In
addition, air compressors will also be housed in the addition that are integral to the casting of
the aluminum ingots.

Spectro Alloys Corp Site Plan Review
May 11, 1993 Planning Commission Agenda Item 5
Page Two
The addition will be located approximately 445 ft. from the highway 55 right -of -way, and as a
result, Planning Staff has asked for landscape enhancements to the boulevard area in a manner
similar to arrangements with KOCH Refining Company where building improvements do not
abut public rights -of -way. Resolution of the previously mentioned ordinance violations and
safety issues are also a primary objective.
A twelve foot diameter by thirty foot tall lime silo will be constructed just north of the bag
house indicated as B.H. #2 on the site plan.
The chlorine storage will be phased out, and a "just -in- time" delivery system will be
implemented. In addition, a liquid fuels storage area will be constructed that has a dike and a
canopy in accordance with applicable standards. The dike will consist of a two foot high by
eight inch thick poured concrete wall completely encircling the storage facility. The City Fire
Marshall has reviewed the specifications provided by the consultant and has found them to be
acceptable.
Spectro Alloys Corp. has indicated that it has a National Pollution Discharge Elimination
System (NPDES) permit in response to the storm water runoff question.
BUILDING MATERIALS AND LANDSCAPING:
The addition will be constructed of painted concrete block consistent with the general character
of the building complex. The lime silo will be screened by the bag house and the liquid fuels
storage area will be painted similar to the buildings with a white canopy.
Six boulevard trees will be installed in a bermed area that separates the parking lot from
S.T.H. 55 in accordance with ordinance standards.
RECOMMENDED MOTION:
Motion to approve the site plan review for the two story addition to Spectro Alloys Corp.
building #3 subject to:
1) providing the City with a copy of the NPDES permit annual report (due in September,
1993) and implementing best management practices for erosion control and stormwater
management as deemed necessary by the City Engineer;
2) conformance with Section 4.9 of Ordinance B City of Rosemount Zoning Ordinance by
removing all trash, junk and debris from the grounds within thirty (30) days:
3) posting of a security in the amount of $1,200 for landscaping in accordance with Section
8.3G of the Ordinance B City of Rosemount Zoning Ordinance; and
4) conformance with all applicable building and fire codes.

CITY OF ROSEMOUNT PLANNING COMMISSION
SPECTRO ALLOYS CORP.:,
Spectro Alloys Corp. occupies a fifteen acre site one mile
east of highway 52 on the north side of highway 55. Spectro
Alloys is an aluminum recycling company employing 90 people
and providing business opportunities for many
subcontractors.
Spectro Alloys purchases millions of pounds of aluminum from
local recycle organizations and converts this aluminum scrap
into ingots. The ingots are cast into as many as one
hundred different certified alloys. Much of Spectro's ingot
production is sold in our area to support the needs of
Minnesota aluminum foundries and aluminum die casting
plants. Spectro Alloys is a low cost producer helping
Minnesota companies remain competitive.
Spectro Alloys Corp. is both a major Minnesota recycler and
a major supplier of aluminum to Minnesota industry.
COMMITMENT TO THE FUTURE:
Over the past ten years Spectro Alloys has reinvested a
major percentage of it's income into rebuilding and
modernizing each of our major manufacturing systems. This
recapitalizing has been done to improve safety, reduce
pollution and improve our competitiveness in the market. We
have been very fortunate to have the services of a highly
professional manufacturing team who has kept our plant
competitive. The aluminum recycling industry has seen many
of it's plants close in recent years but Spectro Alloys has
remained competitive.
SPECTRO ALLOYS IS REQUESTING A PERMIT FOR THE FOLLOWING:
1.0 Installation of a lime silo.
2.0 Motor control and compressor rooms addition.
3.0 Chlorine storage area.
4.0 Diked fuel storage area.
SPECTRO ALLOYS CORP. THE PROBLEMS TO BE CORRECTED:
Spectro Alloys has suffered for years from a lack of
compressed air capacity which has prevented us from
performing simultaneous manufacturing functions. The area
that our present air compressor is located in is to small
and to hot to allow the after cooler to work properly, the
result is, very wet air, a real problem for a unheated
plant. We propose to install a new air compressor with
increased capacity and a small compressor, as a back up to
the main compressor, allowing the main compressor to be
taken off line for preventative maintenance.
Spectro Alloys has two, large, 200 hp blowers, vital to the
operation of our pollution control equipment. The blowers
are of the fixed displacement type, lacking variable speed
drives. However the process is variable and would benefit
from a variable displacement system. Electrical energy
could also be saved with a variable speed drive. Variable
speed equipment is both sensitive and expensive this type of
equipment will require a building to protect it. A building
is also required to protect €he variable speed drives from
temperature extremes.
Our baghouse uses lime injection, the lime is transported by
the existing partial vacuum of the system. This method of
transport lacks the required energy to do a good job and
frequently plugs. With a pressurized injection system we
will not only acquire plug free lime injection we will also
acquire the performance benefit of significant baghouse flow
increase. To make this lime handling improvement a new
motor starter and control room is necessary.
1.0 SPECTRO ALLOYS PROPOSES TO INSTALL A LIME SILO:
Presently Spectro Alloys manually handles hundreds of pounds
of lime filled bags every week. We hand open and manually
pour the contents of the bags into hoppers in our baghouse.
This is a dirty job and could potentially cause a back
injury.
Spectro Alloys is proposing to install a lime silo to
eliminate the existing manual system. This silo will except
sealed bulk delivery, by truck, and will utilize the above
pressurized lime injection system. The lime will then be
transported through sealed piping to the baghouse and
injected into the bag cells.
The standard silo, that is proposed for this project, will
be approximately twelve feet in diameter and thirty feet
tall. For the sake of comparison our baghouse is twenty
eight feet tall and our building number four is thirty four
feet tall. We propose to install the silo on the north end
of our present,baghouse.
Because our industry generates a dust that is difficult for
some bag shaking mechanisms to remove from the bag it has
been necessary for workers to enter the bag house regularly.
We would like to install an advanced designed bag shaking
system that will give us both more air flow and keep our
employees out of the bag house.
Our plant is divided into two manufacturing centers,
presently our pollution equipment electrical energy supply
is a branch taken off of one. If for any reason the number
one production center switch gear must be de- energized the
pollution control equipment for the entire plant is shut
down. We would like to install a stand alone switch and
control center for our pollution control equipment making it
independent of any single plant manufacturing center.
Because our existing pollution control equipment controls
and electrical power sources are auxiliaries to other
systems it makes it very difficult to add improvements, and
it will be almost impossible to add future technologies and
electronic management systems. To take advantage of both
present technologies and future '-systems it will be necessary
to build a dedicated electrical switching and system control
center to allow the installation of best practical pollution
control 'equipment as it becomes available.
2.0 SPECTRO ALLOYS PROPOSES TO BUILD A MOTOR CONTROL ROOM:
Spectro Alloys proposes to build a 19x25 foot addition to
the south west corner of our plant. This proposed addition
would be built at our dock #2 location which has a canopy,
from a plan view prospective the addition will increase the
plant foot print 10x19 feet.
The addition will be built to conform to the same roof line
as the existing building, this will provide adequate
elevation for two floors. The upper level will be our new
compressor room and the lower level will be our new
pollution control, control and motor switching room. The
new pollution control room will have the following initial
equipment installed:
1, Basic electrical entrance switch gear.
2, Basic electrical panels.
3, Motor starters for the new bag shakers.
4, Bag shaking system control panel.
5, Motor starters for the lime injection system.
6, Lime system control panel.
7, Motor starters for the air compressors.
8, 200 hp blowers variable speed drives.
WR Design Structural Engineering has been retained, by
Spectro Alloys, to design the electrical control room, their
drawings are included in this submittal.
3.0 SPECTRO ALLOYS PROPOSES TO BUILD CHLORINE CYLINDER
STORAGE:
Spectro Alloys proposes to build a chlorine cylinder storage
area on the north side of our plant. The City of Rosemount
Fire Marshal indicated to us that our currant open ground
storage method is not acceptable. We have hired Psihos and
asc., Inc. to write the design criteria for the storage
area. This design criteria is enclosed in this submittal.
Spectro has hired WR Design Structural Engineering, to
design the storage area with canopy. This proposed
installation is indicated on the site plan.
4.0 SPECTRO ALLOYS PROPOSES TO BUILD A LIQUID FUEL STORAGE
AREA:
Spectro Alloys proposes to build a diked fuel storage area.
Psihos and Asc., Inc. was retained to create the design
criteria for the project, the criteria is enclosed with this
submittal. Spectro Alloys has hired WR Design Structural
Engineering, to design the canopy covered fuel storage area.
This proposed installation is indicated on the site plan.
FUTURE ITEMS TO BE EXPLORED:
Spectro Alloys will implement operational changes, to the
procedures now being used, that will allow Spectro to stop
using Doyle Path culd -sac as a trailer parking area. It
will take 60 days to implement the changes and complete the
employee training and customer communications necessary to
change the practice.
Spectro Alloys proposes to plant a minimum of six trees on
it's south property line.
Spectro Alloys has a NPDES permit ,for storm water run off,
we are presently developing our Best Management Practices
Plan, the Annual Report is due in September, 1993.
If the members of the planning commission should require
additional information, please do not hesitate to, call on
Jack lewison or myself and we will do our best to assist
you.

Re: OUTSIDE STORAGE OF LIQUID CHLORINE ONE TON CYLINDERS
Dear Mr. Hoklas:
The outdoor storage of liquid chlorine must be within
Article 80, Hazardous Materials, Division I, as per the 1991
Uniform Fire Code.
Chlorine is classified as a toxic, an oxidizer, a
corrosive and it also reacts with water. It therefore must
meet all of the provisions in Article 80 that apply to these
characteristics. These are Sec.80.301, Sec.80.303,
Sec.80.306, Sec.80.310 and Sec.80.314 for Exterior Storage.
The following design parameters are required to fulfill
these sections:
1. A storage plan that indicates the storage
arrangement, including the location and dimensions
of any aisles.
2. The floor shall be sloped not less than 1% to the
containment area.
3. Guard posts are required to protect the storage
tanks from vehicular damage.
4. Secondary containment for one one -ton container of
chlorine shall be provided. The maximum rate of
release from the chlorine valve on the cylinder
is 525 1bs per hour based on the cylinder
temperature of 70 F and releasing it to the
atmosphere. This is equivalent to 43.6 cubic
feet per minute of gas corrected to atmospheric
conditions. This discharge rate is greater than
the rate of release as shown on Table No. 80.303-8
for cylinders.
5. The storage area must not be closer than 75 feet to
any building.
6. The storage area shall not be within 75 feet of air
intakes.
7. The area surrounding the exterior storage area shall
be kept clear of combustible materials for a minimum
5520 HALIFAX LANE EDINA, MINNESOTA 55214 PHONS (612) 920 -4918 FAX (612)-920-1630
APR- 5 -93 MON 18:05 PSIHOS AND ASC TEI 6129204918 P.02
distance of 30 feet.
8. the cylinders stored outdoors shall be stored under
a canopy of noncombustible construction material.
The supports shall also be of noncombustible
construction and the walls shall not obstruct more
than 25% of the perimeter of the storage area.
9. The storage area must be labelled with a maximum
rate of chlorine released at 525 lbs per hour
and must also show the equivalent chlorine
release at 43.6 cubic feet per minute.
10. The storage area must be secured against
unauthorized entry. A fence surrounding the
chlorine storage area may be needed to satisfy
this requirement.
11. These articles include incorporating an automatic
fire sprinkler system for storing toxic gases under
certain conditions. However, water must not be
sprayed into liquid chlorine because this increases
the vaporization of the liquid chlorine. Therefore,
the storage area will include a containment area
that receives any spilled chlorine from the sloped
concrete floor.
12. The storage area must be marked with one inch
letters with appropriate safety labels. This must
include "LIQUID CHLORINE."
0 OUT FACT
Enclosed ie the plot plan received from SPECTRO ALLAYS
which shows the location of the outside storage area for
the liquid chlorine. This shows that the storage area
selected ie greater than 75 feet to the building and is
not within 75 of any air intake. It also shows that the
fuel storage area will be located more than 75 feet
from the chlorine.
The following items are incorporated into the design:
1. A plan showing the storage arrangements is enclosed.
2. The floor will be a concrete slab that will drop in
elevation by 4' over a 16 ft span. This is a 2%
slope.
3. The secondary containment area will be a trench at
the bottom of the slope at the north perimeter
covered by a grate. This will have dimensions of 16
ft long by 2 ft wide by 1 ft deep. This will
2
APR- 6 -93 TUE 10:38 PSIHOS AND ASC TEI 6129204918 P.02
contain the volume of 1 one ton cylinder which is
28.8 cubic feet.
4. The chlorine cylinders will be placed onto two rows
of 6" WY 12.0 on 67' centers which will hold each
row of cylinders. These beams will be leveled by
'shimming and will be anchored to the concrete slab
with steel clips and anchor bolts. Each cylinder
will be stabilized on the beam by placing them
between two 4' X 4' X 6" long angles. These angles
will be welded to the 6" W beam. There will be
two rows of cylinders within the storage area.
5. The east, west and north elevations will have a 6"
high curb. The south elevation will be open since
it must be serviced with a forklift to place and
remove the chlorine cylinders. Any chlorine will
flow on the sloped floor to the north and not out
this open area.
6. Washed crushed rock will be placed and leveled on
the sloped concrete slab. This rock will form a
footing for access if any liquid leaks from the
cylinders.
7. The canopy will be constructed of steel members and
will have a steel roof.
8. A fence will be installed surrounding the chlorine
storage area.
9. Guard poste will be installed at each corner of the
building. The guard posts will be constructed of
4 diameter, concrete filled and set in 3' deep
sonotube footings with a diameter of 15
10. Each side of the building will be labeled with one
inch high letters with the appropriate safety
labels. This will include "LIQUID CHLORINE."
I hereby certify that this plan, specification, or
report was prepared by me or under my direct supervision and
that I am a duly Registered Professional Engineer under the
laws of the State of Minnesota.

Dear Planning Commission Members:
On April 20, 1993 Spectro Alloys Corp. sent you an application
for a building permit which amongst several items included a
request to build an outside storage area for chlorine cylinder
storage. This storage was necessary to supply the plants
production requirements over weekends and holidays.
Spectro believes that we have developed a satisfactory plan,
using just in time delivery and best :management practices to
eliminate the need. for this extra storage. We have just received
agreement from our suppliers to implement the plan. We have a
high level of confidence that this plan will work, but it is
always possible that and unforeseen element may make it necessary
to resubmit the request to build this facility at a later date.
SPECTRO ALLOYS CORP. REQUESTS:
Spectro Alloys requests that our application for a building
permit of outside storage of chlorine be withdrawn from our
submittal of April 20, 1993.

local recycle organizations and converts this aluminum scrap
into ingots. The ingots are cast into as many as one
hundred different certified alloys. Much of Spectro's ingot
production is sold in our area to support the needs of
Minnesota aluminum foundries and aluminum die casting
plants. Spectro Alloys is a low cost producer helping
Minnesota companies remain competitive.
Spectro Alloys Corp. is both a major Minnesota recycler and
a major supplier of aluminum to Minnesota industry.
COMMITMENT TO THE FUTURE:
Over the past ten years Spectro Alloys has reinvested a
major percentage of it's income into rebuilding and
modernizing each of our major manufacturing systems. This
recapitalizing has been done to improve safety, reduce
pollution and improve our competitiveness in the market. We
have been very fortunate to have the services of a highly
professional manufacturing team who has kept our plant
competitive. The aluminum recycling industry has seen many
of it's plants close in recent years but Spectro Alloys has
remained competitive.
SPECTRO ALLOYS IS REQUESTING A PERMIT FOR THE FOLLOWING:
1.0 Installation of a lime silo.
2.0 Motor control and compressor rooms addition.
I
3.0 Chlorine storage area.
4.0 Diked fuel storage area.
SPECTRO ALLOYS CORP. THE PROBLEMS TO BE CORRECTED:
Spectro Alloys has suffered for years from a lack of
compressed air capacity which has prevented us from
performing simultaneous manufacturing functions. The area
that our present air compressor is located in is to small
and to hot to allow the after cooler to work properly, the
result is, very wet air, a real problem for a unheated
plant. We propose to install a new air compressor with
increased capacity and a small compressor, as a back up to
the main compressor, allowing the main compressor to be
taken off line for preventative maintenance.
Spectro Alloys has two, large, 200 hp blowers, vital to the
operation of our pollution control equipment. The blowers
are of the fixed displacement type, lacking variable speed
drives. However..the process is variable and would benefit
from a variable displacement system. Electrical energy
could also be saved with a variable speed drive. Variable
speed equipment is both sensitive and expensive this type of
equipment will require a building to protect it. A building
is also required to protect fhe variable speed drives from
temperature extremes.
Our baghouse uses lime injection, the lime is transported by
the existing partial vacuum of the system. This method of
transport lacks the required energy to do a good job and
frequently plugs. With a pressurized injection system we
will not only acquire plug free lime injection we will also
acquire the performance benefit of significant baghouse flow
increase. To make this lime handling improvement a new
motor starter and control room is necessary.
1.0 SPECTRO ALLOYS PROPOSES TO INSTALL A LIME SILO:
Presently Spectro Alloys manually handles hundreds of pounds
of lime filled bags every week. We hand open and manually
pour the contents of the bags into hoppers in our baghouse.
This is a dirty job and could potentially cause a back
injury.
Spectro Alloys is proposing to install a lime silo to
eliminate the existing manual system. This silo will except
sealed bulk delivery, by truck, and will utilize the above
pressurized lime injection system. The lime will then be
transported through sealed piping to the baghouse and
injected into the bag cells.
The standard silo, that is proposed for this project, will
be approximately twelve feet in diameter and thirty feet
tall. For the sake of comparison our baghouse is twenty
eight feet tall and our building number four is thirty four
feet tall. We propose to install the silo on the north end
of our present,baghouse.
Because our industry generates a dust that is difficult for
some bag shaking mechanisms to remove from the bag it has
been necessary for workers to enter the bag house regularly.
We would like to install an advanced designed bag shaking
system that will give us both more air flow and keep our
employees out of the bag house.
Our plant is divided into two manufacturing centers,
presently our pollution equipment electrical energy supply
is a branch taken off of one. If for any reason the number
one production center switch gear must be de- energized the
pollution control equipment for the entire plant is shut
down. We would like to install a stand alone switch and
control center for our pollution control equipment making it
independent of any single plant manufacturing center.
Because our existing pollution control equipment controls
and electrical power sources are auxiliaries to other
systems it makes it very difficult to add improvements, and
it will be almost impossible to add future technologies and
electronic management systems. To take advantage of both
present technologies and future systems it will be necessary
to build a dedicated electrical switching and system control
center to allow the installation of best practical pollution
control equipment as it becomes available.
2.0 SPECTRO ALLOYS PROPOSES TO BUILD A MOTOR CONTROL ROOM:
Spectro Alloys proposes to build a 19x25 foot addition to
the south west corner of our plant. This proposed addition
would be built at our dock #2 location which has a canopy,
from a plan view prospective the addition will increase the
plant foot print 10x19 feet.
The addition will be built to conform to the same roof line
as the existing building, this will provide adequate
elevation for two floors. The upper level will be our new
compressor room and the lower level will be our new
pollution control, control and motor switching room. The
new pollution control room will have the following initial
equipment installed:
1, Basic electrical entrance switch gear.
2, Basic electrical panels.
3, Motor starters for the new bag shakers.
4, Bag shaking system control panel.
5, Motor starters for the lime injection system.
6, Lime system control panel.
7, Motor starters for the air compressors.
8, 200 hp blowers variable speed drives.
WR Design Structural Engineering has been retained, by
Spectro Alloys, to design the electrical control room, their
drawings are included in this submittal.

3.0 SPECTRO ALLOYS PROPOSES TO BUILD CHLORINE CYLINDER
STORAGE:
Spectro Alloys proposes to build a chlorine cylinder storage
area on the north side of our plant. The City of Rosemount
Fire Marshal indicated to us that our currant open ground
storage method is not acceptable. We have hired Psihos and
asc., Inc. to write the design criteria for the storage
area. This design criteria is enclosed in this submittal.
Spectro has hired WR Design Structural Engineering, to
design the storage area with canopy. This proposed
installation is indicated on the site plan.
4.0 SPECTRO ALLOYS PROPOSES TO BUILD A LIQUID FUEL STORAGE
AREA:
Spectro Alloys proposes to build a diked fuel storage area.
Psihos and Asc., Inc. was retained to create the design
criteria for the project, the criteria is enclosed with this
submittal. Spectro Alloys has hired WR Design Structural
Engineering, to design the canopy covered fuel storage area.
This proposed installation is indicated on the site plan.
FUTURE ITEMS TO BE EXPLORED:
Spectro Alloys will implement operational changes, to the
procedures now being used, that will allow Spectro to stop
using Doyle Path culd -sac as a trailer parking area. It
will take 60 days to implement the changes and complete the
employee training and customer communications necessary to
change the practice.
Spectro Alloys proposes to plant a minimum of six trees on
it's south property line.
Spectro Alloys has a NPDES permit ,for storm water run off,
we are presently developing our Best Management Practices
Plan, the Annual Report is due in September, 1993.
If the members of the planning commission should require
additional information, please do not hesitate to, call on
Jack lewison or myself and we will do our best to assist
you.
