Hearing Notiee, Mailing List
USPCI has petitioned the City to amend the zoning ordinance in order
to permit the disposal of coal ash at the Minnesota Industrial
Cantainment Facility (MICF} . In considering this ordinance, �he
Planning Cammission recommended that the Interim Use Permit be amended
to address the handling of coal ash including monitoring and repor�ing
requirements to the City. At the May 25 regular meeting the
Commission recommended that the attached IUP amendment be considered
by the City Council .
In reviewing the 1992 IUP for MICF it was determined that a public
hearing is required for an IUP amendment. If the prapc�sed permit is
acceptable, it is recommended that the City Council set at public
hearing for it at the next regular meeting.
- The praposed permit sets up requirements for transport, dus� cantrol,
and leachate monitoring. If the Gouncil wishes to consider additional
requirements it woulcl be appropriate to discuss this prior to the
public hearing so staff and consultants can incorporate requiremen�s
into the permit prior to the hearing.
Recommended Action: A MOTTON to set a pu �i� hearing for the
USPCI Tnte�im Use Permit Amendment on June 15 at 8 :D0 p.m. or as
soon thereafter as possible.

Dated M�.y 25, I993 Rea USP�I Caal Ash Text and IUP Aiaendment R�quest
D�ar Ms. Freese:
� have reviewed the questions contaiAed in the above-refezenced docuiaant
and have grepared brief xesgonses. Responses are nivabered to correspond to each
of t2s. KZasseA's comments, and �re as fallows:
I. In oz�der to ensure that the ash tiisposed of at the MICF fa�cility
exhibits t3�e chemical and physical charact�risti�s 4f cOal ash, I
suggest two possible approaches as follows:
�) Cqal a�h froia various faciliti.es �ou�.d be accepted pxovided no
other utat�rials {i.e., coal tar, oxide box tiller, etc,) was
b�.�nd�d with the £u�l tkxat produced the ash. �o ascertain Lhat
this was the case, aommunication directly �+rith the plant
praducing the �sh iaay be required.
b) Alternately, since powez p�ants do on occasion blend other
"fu�ls" with coal w�.th na dis��rnable cDanges in ash
char�acteristics as a r�sult, USPCY could be required to present
baseline physical aAd chemical char�ct�ristics of the coaZ astt
from each plaut dis�+asinq of ash at the i�CF. 2f other
mAter�.ais were to be blended with the coal at the plazat, US�CT
couZd b� required ta submit to the city resu�.ts Qf physic�►l and
chemical characterizatic�n of th� ash from a tes� burn, priar to
acaep�ance cr� the altered ash �or disposal.
2. I agree that it would be �ppropriate for vSPCI to indiaate from which
plants they ar� coasidering acce�ting a�h. If no plants hav� yet
b�e.n identifi�d, then �dditianal infortaation �hou].d be �ubrnitted a�
a condition cf th� permit prior t4 dispasal of �sh at the MIC� {i.e. ,

From: Sheila K{assen, Councilmember �
Re: USPC}Coal Ash l"ext and kUP Amendment Request
Steve, I have had discussions with Frank Hornstein, Executive Director of the Ciean
Water Action AlGance in regard to U�PCI's request for approva( to take coal ash at
their MICF. From thase �iiscussions and reviewing Barr Engineering's report I feei the
foilowing poin#s should be addressed and ask that you have staffi look into thern.
1. Make sure the ast� being received is 100°lo coal ash. lt is my understanding that the
3M Chemolite plant aiso burns solvents and other wastes. {n addition, the NSP A.S.
Ktng piant has appl'+ed #or a permit to burn coal tar and oxide box fitler. {See attached
articie;} This could effect the chernicai make-up of the c�oal ash,
2. Limit eoa! ash to plants within the State of Minnesota. Again, it is my understancling
that the NSP piant in Big Stone, S.D., is undergoing a demonstration projeet co-firing
Refuse Derived Fuei (RDF} with coai. This mixture of garbage to coal is between 1�%0
and 30°Jo. Here, too, if this becomes a trend in Mir�nesota it may effect the caa! ash
content #rom the plants the MICF is senricing. 1 wou{� suggest USPCI inforrn us of
what plants they are dealing with and what the plants burn or will be burning.
3. 1 am told the PCA is going thraugh a rule making process to require coaf burning
facilities to instaif scrubbers to eiiminate Mercury from their ernissions. Whife th�s is
good for air quality, it cauld put rnore Mereury in the ash, which could effect the coal
ash content. Here, i suggest we find out more about this new regulation, when it will
ga into effect, thereby knowing when to re-examine the coal ash content to see if it is
sti11 within non-hazardous limi#s. We may want a re-examinatian c{ause regardless of
this new regulation.
4. We may'want to haue an approvai process over what piants the MlCF is servicing.
Back to the A.S. King plant...if the plant is aliowed to burn the cQal tar and oxide box
#il�er, it will result in �missions high�r in suifur. This eould mean the ash cc3ntent wii! be
higher in suifur which cou[d cause a greater�effect on the concrete structures of the
MiCF.
5. for my comfort level, 1 would Iike to see stronger wording making sure RDF and
MS1N is unacceptable at the M1CF so it is very ciear that al1 parties recognize this as a
"specia{" waste which the M1CF is not buitt to handfe nor buiit with the intention of
handiing, and ta reaffiirm that this is a nan-hazardous waste containment facility.
6. I believe the Barr Engin�ering r+eport assumes the ash wi�! be 1�0%a coal ash. lt
also mentrons the cancerns above, i.e. the effect of sulfur on concrete, not taking
.! } � . . � � . .. . . � . � . . � . . ..
� . � . . � .. � � . � .
MSW, manitoring the facilities serviced and being carefu! not to mix the coa! ash with
other substances that couid eause a change in the chemical make-up. it ais�
addresses operational cancerns regarding dust, more sludge in the leachate that
could efifect the waste water treatment plant, and possible cornbustion of hot ash.
1n closing, f am requesting the points presented be addressed either in the text ar the
tUP. I would aiso suggest we have a discussion to re-acquaint ai1 concerned with the
m4nitoring and reporting requirements af the MICF.
If you have any questions. please feel free to call me at 423-4391.

Report, Correspondence from MWCC,
APplicatic�n & Supporting Materials
Attached is the report fmm Barr Engineeriang regarding the request to disposal of coal ash in the
Minnesota Industrial Containment facility. The report identifies no major issues with allowing coal
ash to be disposect of in this facility, In the report Mr. Radue outlines that some additional actions
be taken by the City if the acceptance of coal ash is cansidered:
- Dust Control (wetting materials, covered transport, limiting height of fly ash fill)
_ Leachate Monitoring
Based on Mr. Radue's analysis, Planning staff believes a favorable recommendation on this zoning
ordinance amendment wouid be appropriate. If the Planning Comrnission agrees that it would be
appropriate to attach the eonditions suggested by Mr. Radue it would be necessary to add an
addendum to USPCI's existing Tnterim Use Permit (IUP). This addendum cari be prepared at your
directian and placed on the May 11 Regular Meeting Agenda for your review. Planning staff
recc�mrnends that the public hearing before the City Council on the Text Amendment be set far May
l8 and that final recommendations on the text amendrnent be made concurrently with tlae IUP
addendum at your next meeting.
Recommended Action: A MCJTION to recommend that the City Council set a Public hearing
on the Zoning Text Amendment for May 1$, 1993.

1.0 INTR(7DUCTION
On March 5, 1993 USPCI, Inc. (USPCI) requested an amendment to th� City of
Rasemount zoning ordinance text to allow disposal of coal ash at the �iinnesota
Industrial Containment Facility (MIGF) . As requested by the Gity of Rosemount,
and in accardan�ce with Barr's proposal af March 12, ;1993, Barr has reviewed the
USPCI Application, "White Paper" , and Waste Acceptance PSan. These documents
were reviewed in light of the discussion questions identi£ied by the
commissioners at the March 23, 1993 Planning Commissian meeting. The general
questions identified are surnmarized as follows:
. What are the physical and chemica2 characteristics of coal ash?
. How can the City ensure that approval of the USPGI plan will resu3.t in
dispasai of coal ash but na other unpermitted types of ash?
. What types of chernical reactions could occur between the coal ash and
ather waste types disposed of at the site7
. Are there envir4nmental benefits associated with aecepting coal ash at
the Minnesota Zndustrial Cantainment Facility (MICF}?
In addition to the questions identified during the planning commissian
meeting, Barr identified the following additional questions:
■ Will dust emi5sions from the facility result froan ash disposal?
. Does disposal of ash have the patential to cause difficulties with
treatrnent of leachate fram the site?
During review af available documents and preparation of this report, it was
assumed that USPGI would consider accepting coal ash from facilities such as the
3M Chemalite facility, from Northern States Pawer Company Metra area pla�ts
(i.e. , Riverside, Black Dog, High Bridg�, �nd A.S, King), and other 1oca1
industxies tbat utilize coa2 far heat or power generation.

2.0 DOCUMENT REVIEW
USPCI has requested madification to the Rosemount 2oning Ordinance to allaw I
acceptance of coal ash at the Minnesota Industriai �antainment Facility (MIGF) .
In addition to the request for zoning ordinance modification, USPCI provided
additional documents which are summari2ed and suppl,emented by additional
information in the following paragraphs.
2.1 White Paper
The "White Papex" submitted by USPCI presents brief overviews of the process
that produces coal ash, the quantities produced in the U.S. anr►ually, the rnajor
constituents and potential environmental impacts from the caal ash, and
alternative uses for coal ash. The primary environmental concerns related to
coal ash disposal are the potential for contaminatic�n of groundwatex or surface
water by metais or suspended ash solids, and the potential for air pollution from
airborne ash particles.
The physi.cal, mineralogical, and chemical properties of ash depend on the
composition af the pa�ent coal, and the boiler design and boiler operating
conditions. Composition of coal a�h, which is the noncdmbustible fraction of
coal, varies slightly, while ash constituent concentrations vary more widely. I
The fine particles remaininq after caal combustion (f1.y ash) generally contain
higher cancentrations of trace elements than the c�arser fraction (bottom ash and
slag) . Typical properties af coal ash are summarized in the folldwing
paragraphs.
Phvsicai Characteristics
Fly ash typically is in the silt to clay si�e range, while bottom ash and
boiler slag generally is in the fin� sand to fine gravel particle siae. Minimum
dry densities for ashes generally are in the range of 45 to b5 paunds per eubic
foat. Maximum dry densities typically fall within the range of b5 to l0U pounds
per Cubic foot. I'

`
Permeability refers ta the rate at which water will seep through a materiai
in a given periad af time. Permeability is influenced by the size and shape of
the particles, the degree of cc�rnpaction, and the viscosity of the permeant.
Bottom ash permeabilities generally fall in the range of 10'' to ll3'' cmisec.
(similar to gravels and sands) while fly ash permeabilities fall witha.n the range
of 5 x 1Q'S to 10'8 cm/sec. (similar to silts and clays) .
Chemical Gharacteristics
Oxides - Oxides of Silicon {Si) , Aluminum {Al} , and Iron (Fe) comprise 95 to
99 percent of coal ash. Cdal ash also contains trace amounts of Calcium {CA3,
Magnesium (Mg) , Titanium {Tij , Sulfur (S), 5odium (Na) , and Potassium (K) oxides,
as well as very smaZl quantities of up to 50 other elements which may include
Boron, Selenium, Chromiurn, Arsenic, and others.
Polycyclic Aromatic Hydrocarbons (PAxs)' - The carbon compounds of most
interest in coal ash are the PAHs. They are produced as a result of incomplete
combustion of fossil fuels. Studies perfarmed by the �lectric Power R�search
Institute (EPRI) and others have generally found that PAii compounds in coal ash ,
are found at concentrations tfiat pose little concern for potential ground water
contaminatian according to EPA critieria.
Dioxins and Furans - Diaxins and Furans refer �o families of chiorine and
benzene based compounds that are present ir► the environment as the result of
manufacture of chemicals such as some pesticides, and frorn a variety of
combustian saurces. The comhustic�n of coal does not appear to result in the
productian of Dioxins or Furans above current analyti�al detection limits.
Radionuclides - Radionuclides are naturally occnrrinq in coal and coal ash,
but at very low ].evels. The available data suggest that coal ash is enriehed
with some radionue3ides as compared to background concentrations, but at leve2s
considerably belflw federal standards.

2.2 Waste Acceptance Plan '
The USPCI waste aeceptance plan poses a series of questions for determina.ng
acceptability of waste for disposal at the MICF. The following are the questions
fram the Waste Acceptance P2an, followed by the probable answer to the question ��
as i� relates to coal ash. In some cases, the answer to the question must be I'
evaluated on a case-by-case basis,
' 2.2. 1 Is the waste one whieh is listed as hazardous by the United
States Environmental Protection Agency {EPA)?
Coal ash is not 3.isted as hazardous waste by the EPA.
2.2.2 Does the waste contain free liquids?
Coal ash may contain free liquids if it is remaved from the plant
using a slurry system, or if it is rem�aved from the flue gas �,
using a wet scz�ubbing process. This must b� determined on a
case-by-case basis.
2.2.3 Is the waste reactive?
Goal ash is not reactive.
2.2,9 Is the waste corrosive?
Coal ash is not corrosive.
2.2.5 Does the waste contain radioaetivity?
Coal ash contains radiaactivity, but at levels below federal ,
standards.
2.2.6 Does the waste contain u�►acc . '
eptabl� organic substances?
Goal ash does not contain unaGc�ptab2e organic suhstanc�s.
23\19\26U\LF.LTR\CET 4
! . I , . . � . � . � .
`
2.2.? Is there conclusive evidence that metals eyaluated under the TGLP
are not present?
Caal combustion wast�s including fly ash, bottam ash, and slag
generally do not leach metals during the TGLP test to the degree
that the ash would be elassified as hazardous under this ral�.
However, results of the TCLP test must be evaluated on a
cass-by-ease basis.
2.2.8 Ts there any other reason why the waste should nat be accepted?
USPCI must consider characteristics of other wastes accepted at
the MICF to deterrnine if the resulting mixture would be cause for
not accepting tfie coal ash. Specific facility design
characteristies must also be considered' in determining if coal
ash should be accepted. For examgle, leachate from coal ash
which is high in suZfate may cause damage to any cancrete
structures it cantacts at the site. The damage results from
sulfate reactidn with the calci.um in the concrete, causing
softening and gradual deterioration of the concrete.
Furthermor�, some adjustment to opera�ions may be required to
handle increased surface wa�er runoff that ean result from
disposal of coal ash, and in particular ths f1y ash portion of
the coal ash.

3.0 POTENTIAL ISSUES OF CQNCERN
3.1 Fugitive Dust Emi.ssions
The potential for wind erosion and fugitive dust emissions from coal ash
depend on climatic faetors sueh as precipitation, evaporation, and wind spsed,
and on 5urface textur� and moisture content of the ash. Vehicular movement on
the ash can also increase the potential for dust generation.
3.2 Leaching
C4nstituents of greatest concern in coal ash leachate with regard to adverse
water quality impacts t.ypically include boron, selenium, total dissolved solids,
and sulfate. Ghromium and arsenie are also of concern for some coal ashes.
I
3.3 Hot Loads
Delivery of hot ash laads to the MI�F could cause comlaustion of ather
materials -disposed of at the facility.
Disposal of coal ash at the MZCF is not likely to have any direct
environmental benefits. The primary environmental benefits to coal ash dispasal
are likely to be indirect in that the MICF site may provide greater environmental
protection than that provided at the location where the ash was previously
disposed.
23\19\260\LF.LTR\CET �
� � ` cambustion of municipal salid waste are less predictable. As a result
` of the visual differences, routine sit� inspections typically can
detect the dumping af unauthorized ash from munieipal solid waste
incineration or ather facilities. Furtherznore, ineornplete combustipn
of refuse cleriveri fuel can result in the generation of inethane and
hydrogen sul.fide gas after ash disposal. Due to the inconsistencies
inherent in ths nature of ash from municipal solid waste incineratars,
it wou].d be appropriate for the Czty of Rosemount ta continue to
forbid disposal of sueh ash a� the M�CF.

Mr. Stephan 7ilk
City of Rosemount
2$75 - 14Sth Street West
P.O. Box 510
Rosemount, Mn 55(#�i8
Dear Mr. Jilk:
USPCI, Inc. is requesting an amendment to the Rosemount Zoning Urdinance text to allow the
acceptance of coal ash at the Minnesota Industrial ContainmenC Faciiity (MICF). USPCI is '�,
making this request because it believes that coal ash is a non-hazardous industrial waste of the '',
type that MICF was designed to effectiuely contain with no harmful effects tc�the envimnrnent. ,
As you recall, the pertinent portions of the zan�ng ordinance were written while there was debate I
over the permitting of the Dakota County Resource Recouery facility. There was concern that
a State-of-the-Art I.and Disposal facility such as the MICF might `be used for municipal �,
incinerator ash dispasal if the incinerator was constructed. The City took stegs to alleviate this ',
public concern, with the support of USPCI, by �xcluding ash from municipal waste incineration
or resource recovery from being aceepted at non-hazardous industrial waste facilities in ,
Rosemount. '�
USPCI understands the intent of the ordinance to prevent ash from municipal waste combustion,
generated at incinerators and some power plants such as NSF's Red Wing facility, from being I
sent to the MICF. Ash from coal-burning power plants, however, has taeneficial properties that
are desirable in the chemistry af eontainment cells. II�
In many areas, coal ash is used as a solidi.fication agent to bind liquid waste prior to disposal. II,
Coai ash is cunently being disposed of at other facilities in Dakvta County. Under MICF's ',
Waste Acceptance Plan, any cc�al ash that is accepted at the facility must undergo the same ,
rigorous sampling and testing procedures that any other waste must undergo grior to acceptance. ,
USPCI feels that this is a waste stream that may be ben�ficialiy re-used at the facility as a cover ,
material inside the cell, with appropriate approvais from the Iv�PCA and Dakota County. ',

COAL ASH:
ISSUES AND ANSWERS �
By Frerlerick H. Gustin, P.E.
Senior Project Engineer, Environmental Affairs
KBK Enterprises, 1nc., Kennesaw, GA
This paper will attempt to define the nature af ash that is produced from burning
coaL
What is ash?
There are two by-praducts of combus#ion - ases and solids. Ash is the solid b -
9 Y
product of cambustion. 1t is the non-combustible material that is contained in the
fuel. The type oiash produced is a result of the type of fue/that is burned and of
the type of boiler that is used to burn that fuel. Most electric utitities bum coal or
oil to produce hea# inside a boiler, which in turn converts water to pressurized
steam in tubes inside the boiler. The steam can either be used directly for
heating buildings or in industrial processes, or else it is used to#urn a turbine
coupled ta an eleetrieal generator. Other types af fuei that are commonly burned
in the United States to produce steam and/ar electricity are natural gas and ,
municipaf salid waste (MSW)-
How is ash produced? • ,
There are a nurnber of different types of boilers that are in use today to burn - '�
coaL The most prevalent electric utility design is the type where finely
pulverized coal, at about the consistency of face powder, is blown into the boiler
and burned in a fire ball that is suspended in mid-air. This is called pulverized
coal suspension firing. The othermajor boiler designs are the staker boiler and
the c c/one boiler I�a.
Y
There are two types a€ ash that are praduced by burn�ng coal. Fly ash is fiir�e ,,
particulate matter that is entrained in the fiue gases and cap#ured by a beghouse
or electrostatic precipitator. Before air pollution contro( devices were placed into ,
common usage, this was the smoke ec>ming out of the stack. Bottom ash is '`
caarser, mol#en, stag-like rna#erial that drops to the bottom of the boiler and is
pulled ou# mechanically after being caofed.
How much coal ash is praduced annuafiy? I
The American CoalAsh As�oeiation estimates thaf in 1991, utilities in the U.S.
bumed`approxima#ely 772,316,000 tons of c4aL Thfs r�sulted in the praduetion
of 51,000,000 tans of fly ash, 13,300fl,000 tons of battorn ash, and fi,05Q,000
tons af taailer slag. Also produced were 18,100,000 tons of"FGD (f{ue gas
desulfurization) material", pcimarily wet and dry scrubber residues I�I.
��
. � �
Coai ash is a very consistent mate�ial, both from a physical �nd chemical
standpoint. Most electricaf utilities try to lock in long-term contracts for coai
suppiies from a single mine at favarable prices. The quality of coal from a single
seam or regian tends#o be eyctremely consistent day in and day out, year in and
year out, making for eansistent ce►mbustion conditions inside the boiler. This is
verified bythe purchaser on a regular basis through laboratory analysis of
samples for their BTU, ash, moisture, and sulfur contents. These qualities
certainly vary from region to region of the eountry, but as coal t�nds to be a
relatively homogeneous material, eoal ash frorn a single source is also
homogeneous.
The following table shaws ranges of the major constituents of coal ash.
RANGE OF MAJQR CONSTITUENTS BY CQAL TYPE t3��1

Siiiea (Si02} 7.0-68 17-58 6.0-40
Alumina (AI�03) 4.0-39 4.0-39 4.Q-26
Ferric Oxide (Fe�03) 2.0-44 3.Q-19 1.0-34
Calcium Oxide (Ca�) 0.7-36 2.2-52 12,4-52
Sodium Oxide (Na0) 0.2-3.0 -- 0.2-28
Magnesium Oxide {Mg0) 0.1-4.Q 0.5-8.0 2.8-14

Sulfur Trioxide (S03) 0.1-32 3.0-1 G 8,3-32
What are the environmental impacts of ash disposal?
Environmental impact can occur via three mechanisrns: Gontaminat'ron of
surface waters by runoff, confamination of groundwafer by leaching o#
can#arr�inants, and surface ec�ntamination of surrounding areas by airborne fine
par�iculate matter. Nowever, these are not issues in the disposal of coal ash
due to the following reasons:
• Runoff is contained within the disposal cell, preventing contamination of
surface waters. ,
• Contaminants are prevented fr�m reaching the groundwater through#he use
of synthetic and natural iiners, and collection and treatment of any leachate.
• Fine particulates are prevented from becaming airborne by maintai�ing the
ash in a wet condition, and the crust that forms when the ash has dried in
place.
. . .
, '
Coal ash contains traee quanti#ies of most heavy metais in concentrations sirnilar
to soils. in most cases, Ieachability af heavy metals approaches drinking water
standards, However, routine testing of ash prior to acceptance#or disposat
insures it's non-hazardous nature.
Are there uses for coal ash? '
Coal ash has many uses. The most economicalty valuable is that of fly ash in
portland cement cancrete and concrete praducts. More than 7.6 million tons of
fly ash were soid in 1991 for this purpose. About one million torrs of bottom ash
and boiler siag were used in concrete products, primarily concrete blocks. :Other
uses include struct�rral filis, road bases, ice control (salt substitute), b{asting grit
and roafing granufes, and waste stabilization and solidificat"ron to name bu# a few
[21,
1Nhat are the standards and specifications for its use?
Fly ash that is sold for use in concrete must meet rigid quality requirements for
its chamical composition and physical characteristics. This is governed by a
specification developed by the American Society for Testing and Ma#erials
(ASTM) entitled "C-618, Standard�pecification for Fty Ash and Raw or Ca/cined
Natura/Pvzzo/an fvr Use as a Mineral Admixture in Portland Cement Goncrete"
�51.Specifications and standards are deveioped in order to pratect the customer, i
and to provide a common ground for cammerce and science.

FLY ASH USED AS A SArIITARY LANDFILL COVER '
Fly ash and bottom ash have been successfully used ir� sanitary 'i
landfill operations as a cover and compaction media. Research
has demonstrated that fly ash is particularly effective in I�
accelerating decomposition of household refuse and aid's in the
compaction of the refuse which would extend the exp�cted life
of such landfills . The ash cou7.d become a valuable asset for
landfill a.perators in areas where cover material is in short
supply or sin�ply not available. '
.•
SQme advantages ta be gained from using ash in these areas arer
1 . Percolatian thraugh fi11 is r�au��a due ta compact-
ability of fly ash thus reducing leacheate to ground ,
and surface waters; ..
2 . Ash is more inert than other readily availab3,e mate-
rials having been fired thraugh a temperature of 1Q�0°F; �
3 . Moisture content of f�y ash can be varied and controlled �
to suit operator' s needs ;
4 . Ash is available 365 days a year while, because of '
freezing oR wet conditions , soil or other cover mate- �'�
rials may be unusable.

size from +3/8 to - 200 mesh . It is sound and durab'le and has
a gaod affznity for emulsified asphalt .
Bottam asl� has been utilized as a base cou.rse aggregate in
the repaving of 40 to 45 miles of rural secondary roads in
1�'est Virginia . The material was cold- lai.d wi��th a paver or
spreader box �oit}� adequate compaction achieved from several
passes with a pneumatic roller, followed by a ste�l -drum

FLY ASH AS A FILTRATION MEDIUM FOR
SN5ULATING OILS USED BY UTILTTIES
The similarities in chemical. constituency of fly ash when compared
to Fuller' s earth has lead to the testing of f1y ash as a fil.tration
medium for cle�ning used insulating oil.
Fuller' s earth is the commercial term applied to the natural bleach- .
ing elays originating in the southeas�ern United States (principal.ly
Fla. and Ga.�) . These clays are either granulated ar pulverized and
are used for filteration by. either the percolation or contacting
process. The following table is a comparison af the typical chemical
analyses of fIy ash to Fu11er's earth. The analyses show that the
chemical compositi.on of the fly ash is very close tc� that of the
Fuller' s earth �xcept for the higher organic mafiter present: in the
Fuller' s earth. •

Fly Ash As An A��re�;ate For The
Stabilzzation of Hi�hway Suberades.
The Qutstandsng property which makes fly ash a viable engineerin�; material
is its po;zolanic nature, The poxzolanic reactic�n between fly ash and
lzne can result in a material of substantial strength. Natural pc�zzolans,
such as volcanic ash, have been hi�hly regarded con�truction, materia2s
since ancient times, This property of fly ash has been employed in
various phases of hi�h�ay construction in this country, and abroad. F2y
ash stabi2ized with lime and/or cement has been u`sed in base and subbase
courses for roadway pavements. In additian tn the po2zolanic nature
of the fly ash, the relatively light unit wei�ht af fiy ash has made
it a.particularly suitable fill. material aver areas of weak sub�rade
where heavier materials could_ cause excessive settlement or f�ilure in '
the weak soils. In addition, any self-hardenin� properties which a
fly ash may possess tend to increase the fly ash's shear strength wzth
tine, rendering the fly ash a very stable material capable, in many
cases, of sustaining substan�ial loads.

Rec U3PCI Request to Accept Coal Ash
Dear Ms. Freese:
I have reviewed your FAX transmittal of April 14, 1993 from the
Metropolitan Waste Control Commission (MWCC) . The MWGG has influent and
effluent eompliance requirements for their wastewater treatment facilities and
as such, has a thorough understanding of the impaets various influent waste
streams may have on effluent quality. Therefore, it is appropriate for the MWCG
to deterrnine what additional constituents, if any, should be evaluated during
testing of leachate from USPCI's MICF. 5ince the MWCC has identified no
additional leachate testing requirements, it would appear as stated in their I'
letter, that leachate from the MICF will be aaceptable for diseharge to the MWCC
treatment facilitzes.
Given the requirement that leachate from the MIGF be temporarily stored �
pending results of leachate testing, it is my belief that this provides adequate
opportunity for evaluating whether or not to discharge Zeachate. As indiaated
in zny letter dated Apri1 8, 1993, dispo$al af coal ash at the MIGF appears to '
pose little risk to the environment pravided the waste acceptance plan and
facility operations plan is properly implemented. Therefore, I recommend the j
�a.ty �+f Rasem�unt modify the zoning ordinance as necessary to allaw disposal of '
coal ash at USPCI`s MICF.
If you have any questions regarding recommendatians presented herein, �
please feel free to ca11 me at 832-2871.

RE: MICF Coal Ash
Dear Ms. Freese:
Attached you wi11 find a xeport from LeeAnn Johnson of MWCC's R & '�
D division concerning fly ash leacha�e/Rosemaunt WWTP toxicity
testing. This pro�ect` was conducted in respanse to your concerns i
regarding the acceptance of fly ash at the Minnesota Industrial I
Containment, Facility (MICF) in Rosemount. Ms. Johnson's
conclusions confirm our initial belief that acceptance of coa3 ash
�
at the MICF will not present a problam with leachate disposal into 'i
the MWCC system.
According to Rick Potrament of MICF they wi�.l not be accepting coal
fly ash for waste disposal per se. They intend to use it as a '
stabilizer on their internal roadways and, maybe in the <future,
offer a.t to their eustomers as a salidificatior� agent fflr wastes
which may contain some free liquids. In that case, the portion of
` leachate fram f].y ash would be much less than what was estimated
for the toxicity tests.
If you have any questions regarding the attached report, or any
other concerns about the MICF permit or discharge, please call me ,
at 7'72-7009.

Subject: K�ng's Leachate Toxicity Testing
INTRODUCTiON
This memo wilC summarize tests conducted by the Research and
Deve(opment Division to examine the toxicity of King's fly ash leacfiate. It is
anticipated �thai a similar leachate will be dischacged to the Rosemount wastewater
treatment plant if fly ash is aecepted at the industrial landfill in Rosemount: The
testing consisted of two parts:
[�l Determination of Rosemount plant axygen uptake rates in control systems
and in systems amended with various concentrations af fly ash leachate.
These tests were performed using a Bioscience Management tnc. B1-10Q0
electrolytic respirometer.
[2] Measurernent of MicrotoxTM toxieity c�# the fly ash leachate.
RESPIRUMETRY
The Bioseience Management Bt-1Q00 electrolytic respirometer measures
axygen consumption by micraorganisms metabolizing organic and inarg�nic P
substrates in wastewatec. The presence of tox're substances in toxic amounts
inhibits the metaholic activity of the microbial poputation, and causes a decrease in
oxygen uptake rates and/or a decrease in the total amount of oxygen consumed
over the course of the test.
In the standard protocol, biamass and wastewater from the affected
trea#ment plant�are used in the test system. Thts mxxture is amended with
concentrations of an industriat discharge {or chemicatf representing realistic to
warst case conditions #or the treatment plant. Oxygen consumption in the test `
reactors are compared with oxygen consurnption in cantrol reactors which do noi
rece,ive the industria! waste.
A schematic ot a Bf-1 Q00 standard reactor is shown in Appendix B alang

PRINCIPLES OF TME MICROT�X TEST
The Microtox toxieity test is a commerciatiy-availabte toxicity test system �'
<manufactured and distributed by Microbics Corporation, Inc. Like other bioassay
systems, it chatlenges a iiving organism with a test sampie and measures a
response frorn the organisrn. The test arganism (also called the "reagent"1 is the �
luminescent bacterium, Photobacterium phosphoreum, a marine isotate which II
produces light as part of its normal metabolism. The iight output of the reagent is
measured before and after the reagent is exposed to the test sample under
controlled conditions of time and temperatur�. When the reagent's metabol'rsm is
inhibited by the presence of toxic substances, its tight output is reduced.
In the standard Microtox test a range of sample concentrations are examined
along with a non-toxic positive reagent control. The data is used to construct a
dose-response curve from v�rhich an EC50 vatue is caiculated. The EC50 is the ;'
effect�ve concentration at which there is a 5t}°!o reduction in light output due to !I
toxicity. EC50 values can be compared in a relative way: A sample with a Iow EC50 ',
value is more toxic than a sample with a high EC� value. in ef#ect, a lower ',
concentratian of a more toxic sample will cause the same tesponse (50% light '�
{ass) as a higher concentration of a Iess taxic sample. I
EXPERtMENTAL I

included in Appendix A.
RESULTS AND QISCUSSfON
Res�irometry .
The results of the respirometer test are summarized in the attached figure.
The accumulated oxygen demand graph shows the totai amount of oxygen utilized
by the biomass in each respirometer reactor over the course of the experiment.
Eact� piot represents the average resuits Qf duplicate reactors except for the "1 °70"
plat where data from only one reactor is presented. The stir bar in the secand
"1 °lo" reactor uncoupied fior several fiours making these results �nvalid.
As we have already discussed, the first day's data could nat be used
because the respirometer had been improperty programmed. The problem was
corrected on the second day of the incubation, and the data fnr the remainder of
the test was collected correctly. The data presented in the accumulated axygen
demand figure was "zeroed" on day two to bring all reactors to the same starting
point, 1 am confident that the results we obtained far the remainder of the test are
valid and repr�sent the microbia! activity in the reactors.
Sased on the results ofi this testing, there was no apparent oxygen uptake
inhibition at any concentration af fly ash leachate examined. You have indicated
that the indust�ial landfil+ is atfowed to discharge a maximum o# 30,Q00 galians of
leachate per day, or approximately five percent of the total flow to the Rasemount
plant. The highest concentration examined here, five percent leachate, would
represent a worst case scenario for f!y ash in which all of the discharged Jeachate
consisted only of fly ask� ieachate. in fact, axygen uptak� was slightly higher in
the reactors receiving fly ash than in the control reactvrs.
Microtox �
The resul#s o# the Microtox analysis and data reduction for King`s fly a�h
leachate are attached. The tesfi did not provide a sufficient r�ur�ber of vatid data
points to calcutate an EG50 value for the sample, h�wever, a review of the.gamma
vatues generated during the test indicates that the sample is not toxic. As
explained in Appendix A, the.�amma value is the ratia o# light remaining to iight
fost due ta toxic exposure. A smali gamma ualue, i.e, cic�se ta zero, indicates low
toxicity. For the leachate sample the gamma value at the highest cancentfation
was negative at both time points indicating a small stimulatory ef#ect. A}though
we �7ave not analyzed a Rosemount plant influent s�mple for Microtox toxicity, we
have anafyzed hundreds af plant influent samp(es from other treatment plants in
3
, `
<.
. '
the MWCC system including Metro, Seneca, Hastings, Anoka, and Stiliwater.
These samples typically have�a Microtox EC50 value in the range of 2-50°l0, and we
have atways detected toxicity in these samples. My conclusion based on these
comparisons is that the King's leachate is actually less toxic than typical municipat '
wastewater. . '
� CONCLUSIONS
Based on the results of xhese respirometer and Microto� tests, it does not
appear that King's fly ash leachate is particularly toxic either in terms of Mierotc�x
toxicity or inhibition of wastew�ier microorganisms. As such it should not cause
process interferences in the Rosemount t��atment plant, Since the feachate tested
here is not the same Ieachate that would be discharged frc�m the industrial landfill
in F�asemouni, it may be prudent to conduct further testing if/when the (andfill
accepts fly ash or if the treatment plant develops problems after the fJy ash is
� accepted.

Anatyzer preparation [Fig. A-2(a?l
'I . 1 .0 ml of reconstitution solution was added to a euvette in the 5°C
precooling weli.
Z. 1,0 mt o# diluent was added to cuvettes in A1 through A4.
3. 500 �ri of diluent was added to cuvettes in B1 through B5.
Sample preparation [Fig. A-Z(b)] -,
1. 2.5 ml of sample was added to a cuvette in A5, and the sample was
osmoticaliy adjusted by adding 250 ,ul of MOAS to tfie cuvette and mixing.
2. Two-fold serial dilutions of the sarnple were prepared as follows:
a, 1 .0 ml w�s transferred frorn A5 to A4, and A4 mixed.
b. 1 .0 ml was transferred from A4 ta A3, and A3 mixed.
c. 1,4 m1 w�s transferred fram A3 to A2, and A2 mixed.
d. No sample was added to A1 whieh was used as the control (blank?.
3. Dilutions were alfowed to equilibrate to 15°C for 5 minutes.
Reagent preparation [Fig. A-2(c)�
1 . A vial of Microtox reagent waS reconstitu�ed by rapidly adding the
reconstitution solution from the precooling well to a fresh vial o# freeze-dried
reagent; mixing thoroughly, and transferring the mixture back to the cuvette
in the precoc�ling well.
2. 1� ,ul of the reconstituted reagent was transferred to B1 through B5, and
mixed.
3, The reagent suspensions in B1 to B5 were allowed to stabilize fQr 15
minutes prior to t�se,

Assay procedure [Fig. A-2(d)l ,'
1 . To measure lo Hght levels: ta) c�vette B� Cblank� was placed into the turret ;
. weli, fhe turret was closed, the light leve! was set to approximatety 090,
and the.value recorded; (bI the remaining cuvettes, B2 to B5, were similariy
cycied through the turret w�li to obtain In light levels without making any
adjustments to the analyzer.
2. Immediatefy foliowing the initial readings, the foilowing 500 �1 transfers �
were rnade using the pipettor to m�x the samples: A1 to B1, A2 to 82, A3
to B3, A4 to B4, A5 to B5. �i
3. Five and fifteen minutes after the last lo light levei was taksn, the cuvettes
were again cycied through the turret well to obtain 15 and t15 Iight levels.
4. Atl tight readings were either recorded on a strip chart.recorder or read
directly off the analyzer digital display, Numbers and sample in#ormation
were recorded on a standard worksheet.
