Statement of Work Encapsulation of Idaho National Engineering and Environmental
    Laboratory Waste Experimental Reduction Facility Fly Ash by Mixing with
                          Polysiloxane March 15, 1998

Background

The Idaho National Engineering and Environmental Laboratory has accumulated
approximately 100 55-gal drums of baghouse filter fly ash as part of
incineration of mixed low level waste in the Waste Experimental Reduction
Facility (WERF). This ash has a multitude of radionuclides (at very low levels)
and several heavy metals including lead, cadmium, and antimony. The ash is
physically a finely divided powder with about 30% ignitables comprised of
carbonous materials. Table 1 gives an assay of the radionuclide content and
chemical composition of one incineration campaign called RUN 87. In addition,
Table 2 attached gives an approximate chemical breakdown including chloride,
sulfate, and oxide contents of the material. One of the materials present in all
the ash is a relatively high Zinc content (approximately 17%). Currently, WERF
is examining methods other than using Portland cement stabilization for
encapsulation and eventual disposal. WERF's criteria for successful
encapsulation is to meet at least 60 psi compressive strength and pass Toxicity
Characteristic Leach Procedure O~CLP) for the heavy metals in the final waste
form.

Scope

The scope of this statement of work is to evaluate, in laboratory scale,
encapsulation of both surrogate materials and actual WERF ash with the
Subcontractor's proprietarv polysiloxane. The scope includes specific testing by
the Subcontractor and an outside private/certified laboratory with the
proprietary patent pending polysiloxane. Approximately 4548 of the material
shall be supplied by INEEL to the Subcontractor. The Subcontractor shall first
develop a surrogate material and perform mixing studies of the polysiloxane and
surrogate as4 compressive strength testing of the resultant waste forms and in
addition shall coordinate independent private laboratory testing for Toxicity
Characteristic Leach Procedure (TCLP) on the mixture of surrogate ash and
polysiloxane. Next, the Subcontractor shall perform a hot study with the 454g of
ash in which the most promising mixing parameters from the surrogate testing
shall be used to formulate 2" diameter by 4" long cylinders of waste form. These
cylinders shall be tested for compressive strength and samples shall be prepared
and shipped to an outside laboratory (with the proper certification to handle
this material). In addition, the Subcontractor shall fllpplyy a plan with cost
estimate for implementing this technology at the INEEL for application to the
approximately 100 drums of WERF ash.

Technical Tasks

The Subcontractor shall formulate a version of their patent pending polysiloxane
encapsulation material for use in encapsulating the WERF ash. The material
<PAGE>
 
should be of a viscosity that lends itself to mixing of the ash and
encapsulating agent with minimum energy input such that it can easily be formed
into monoliths by extruding the material or simply pouring the material. The
final matrix must be able to pass Toxicity Characteristic Leach Procedure
(TCLP). In addition, the ~ product must have at least 60 psi unconfined
compressive strength such that the monoliths can easily be used in shallow land
burial for final disposal. The material shall be nominally planned to be mixed
at 40% by mass ash but higher waste loadings are desirable. As part of the
mixing studies, the heat generation during curing shall be determined.

2.   The Subcontractor shall take possession at testing headquarters located at
the University of Akron of approximately 4548 of the WERF ash currently stored
at the INEEL. Only those laboratory spaces examined by the INEEL Environmental
Audit of 1997 can be utilized. It is the responsibility of the Subcontractor to
ensure that the current Nuclear Regulatory License for the University of Akron
is compatible with the radionuclides listed on the attached tables. Once the ash
has been received and tested by the Subcontractor, all material shall be shipped
at the Subcontractor's expense back to the INEEL for final disposal.

3.   The Subcontractor shall create from the final polysiloxane formulation 6
examples of a non radioactive non hazardous sample (2" cylinders are adequate)
of the proprietary polysiloxane and surrogate ash mixtures for display purposes.
These samples shall be shipped to the INEEL according to the schedule below.

4.   The Subcontractor shall formulate sufficient samples to give to an
independent EPA certified laboratory to perform Toxicity Characteristic Leach
Procedure testing for heavy metals. The Subcontractor and the independent
laboratory are responsible for disposal of the material.

5.   The Subcontractor shall provide a cost estimate to process the
approximately 100 55 gal. Drums of WERF ash.  Only the equipment, engineering,
and encapsulant costs should be included.

6.   The Subcontractor shall provide a letter progress report every three weeks
defining progress on the various phases of the project.

7.   The Subcontractor shall provide input to a test plan that shall be
published by INEEL. The input shall include testing procedures, list of
equipment, quality control, safety, and a discussion of analytical methods. A
hard copy and Word disc shall be supplied.

8.   The Subcontractor shall document the results of all testing in a final
letter report with a clearly stated conclusions section. A hardcopy and Word
disc copy shall be supplied.

INEEL Supplied Items:

1.   INEEL shall supply the Subcontractor with nominally 454g. of WERF ash
packaged in a DOT approved container.
2.   INEEL shall use the Subcontractor input and publish the test plan.
3.   INEEL shall coordinate with the Subcontractor to observe and review key
testing.
4.   INEEL shall use the Subcontractor letter report and write an overall
evaluation report to be published at the end of the fiscal year.
<PAGE>
 
Technical Requirements

Satisfactory completion of the tasks shall be receipt of the test plan input,
progress reports that show routine progress toward completion of testing, and
receipt of the final analysis report. Details of these items are in this
Statement of Work.

Deliverables

Waste Management Plan for TCLP testing - Due Date: April 15, 1998.
WERF ash Received by the Subcontractor-no sooner than 20 days after LMITCO
approval of Waste Management Plan Test Plan.
Input to INEEL - Due Date: April 15, 1998.
Surrogate Test Results Interim Report - Due Date: April 27, 1998.
Final Report Delivered to INEEL-August 30, 1998.

Special Considerations

The Subcontractor shall maintain an exact inventory of both the surrogate waste
(hazardous but no radionuclides) and the WERF ash. For the WERF ash, all
material shall be returned to the INEEL except that which is used for TCLP
testing.

           Revised Statement of Work-Orbit Technologies Polysiloxane
                 Encapsulation of Calcined Surrogate Material

The current statement of work for Orbit Technologies involves encapsulation of
WERF ash. As an adder, additional work was given to perform encapsulation of a
calcine waste surrogate material. This revised statement of work redirects the
effort to eliminate any further work on the WERF fly ash and to focus the
remaining effort on the low-level waste Calcine surrogate material.

Scope:
The scope of this statement of work is to perform an encapsulation study on the
low-level waste fraction of the calcine waste surrogate material. The first step
will be to obtain necessary materials to formulate the calcine surrogate
material.  Once the chemicals are obtained, the surrogate material will be
formulated as specified in the attachment. The need for a pretreatment
methodology will be assessed and developed if needed. Next, the study will
involve a laboratory mixing evaluation in which at least three waste forms will
be mixed at between 35% and 60% by mass of the calcined surrogate and Orbit
Technologies' proprietary polysiloxane material. For these materials,
compressive strength of the resultant waste form and "in house" leachability
evaluations will. be accomplished. An in-house leach index will be established
for the major contaminants in the waste form. Based on the mixing study and the
"in-house" leaching new waste forms will be mixed for outside laboratory testing
for Toxicity Characteristic Leach Procedure (TCLP) protocol for the contaminants
in the surrogate material. At least two different waste loadings at as high
waste loading as possible will be given to the outside independent laboratory
for evaluation.

Specific Items to be either supplied by Orbit or coordinated by Orbit
Technologies:

1.   Orbit will formulate the polysiloxane mixture including any pretreatment
materials deemed necessary. The viscosity should be such that lends to
application in a standard paddle wheel mixing system. It is desirable to
maximize the waste loadings during the mixing study with 35% waste by mass being
the lowest acceptable waste loading with 60% being a desirable target value.
<PAGE>
 
The final waste forms at the highest loadings will be tested for both
compressive strength and leachability in house and for at least two of the
samples; the waste forms will undergo TCLP testing at an independent laboratory.

2.   Orbit Technologies will be completely responsible for the surrogate waste
materials and any disposal required.

3.   Orbit Technologies will formulate 6 samples of the calcined surrogate
without the contaminants of concern. The samples will be approximately 2'' in
diameter and 4" long and will be shipped to the project engineer, GUY LOOMIS at
LMITCO, 2525 Freemont, Idaho Falls Idaho 8J415MS 3710.

4.   Orbit Technologies will evaluate the heat generation (if anv~ during the
mixing and cwing process.

5.   Orbit will provide a cost estimate per cu. ft. to process and encapsulate
the low-level waste fraction.

6.   Orbit will provide a letter report showing expected methodology. The test
plan should be written in WORD and a disc supplied. In addition, Orbit should
provide verbal or written updates on progress every two weeks after acceptance
of the contract.

7.   Orbit will document all results in a final fetter report with clearly
stated conclusion~-~-hardcopy and disc on WORD should be supplied.

INEEL Supplied Items

I.   INEEL will use the Orbit letter report and write an overall evaluation
report to be published at the end of the fiscal year.
