equipment, logistics, transportation and business coordination to
market and sell Ash, and products made from Ash, as set forth in this
Agreement. Markets for Other Byproducts; Future Agreements. ISG
shall manage Other Byproducts through disposal as set forth in this
Agreement, but shall notify SRP if it becomes aware of new markets for
Other Byproducts, or products made from these substances. If new
markets are identified by ISG, the Parties may negotiate an agreement
providing for the marketing and sale of Other Byproducts generated at

4.3.2 Schedule of Annual Purchases. For each year that this
Agreement is in effect, ISG shall provide SRP with an annual schedule
of anticipated purchases of Ash and Other Byproducts. The schedule will
include 12 individual months. ISG shall revise the schedule whenever a
material change can be reasonably anticipated by ISG, and shall provide
a revised copy to SRP. The operating Representatives shall agree on due
dates for the schedule.

4.4 Disposal.

4.4.1 Disposal Responsibility. ISG shall furnish all supervision, labor, services, and equipment, and perform all operations required to haul, handle, and permanently store Ash and Other Byproducts, as follows: Transportation. ISG shall transport Ash and Other
Byproducts, other than Crystallizer Salt, to the NGS Ash Disposal Area. Deposit. ISG shall dispose of all Ash and Other
Byproducts, other than Crystallizer Salt, that are not used by SRP or
sold to ISG by placing them within the NGS Ash Disposal Area, as has
been the historical practice of SRP and its contractors during the term
of the NGS Lease. If the deposition material is comprised of Bottom Ash
and Fly Ash, the Fly Ash should be laid down to a thickness of 2 feet
with a 6-inch cap of Bottom Ash on top. If the deposition material is
comprised of Bottom Ash and Scrubber

Page 10 of 44

Byproduct, the Bottom Ash should be laid down to a thickness of 2 feet
with a one-foot cap of Scrubber Byproduct on top. The surface layer of
each embankment face and surface contour must be comprised of a 6 inch
layer of Bottom Ash over a 2 foot layer of Fly Ash or, if there is
insufficient Fly Ash available to complete a 2 foot layer, a 2 foot
layer of Scrubber Byproduct over a 2 foot layer of Bottom Ash. Site Preparation. ISG shall prepare the site before
placement of material. Before placing material in outcropping Navajo
sandstone, ISG shall excavate and remove all existing vegetation and
debris in the area, inspect all exposed areas, and fill all wide cracks
and fractures in the exposed bedrock with properly compacted Fly Ash
fill. Before placing material in native dune sand ISG shall excavate
and remove all existing vegetation and debris in the area. The dune
sand foundation should then be compacted prior to placing Fly Ash by
pre-wetting the surface by sprinkling with water. Intensive sprinkling
will be required to thoroughly wet the dune sands in order that the
densification of deeper sand layers by vibratory methods will be
effective. ISG shall then compact the dune sand with the vibratory
roller "RayGo-Rascal" - Model 600A operating at a speed of
approximately 2.0 to 2.5 feet per second, using a minimum of 5 passes.
Any other vibratory roller that will produce equivalent dynamic
compactive effort can be used to compact the dune sand. Comp action. ISG shall compact the material deposited
in the Ash Disposal Area, as it is deposited. Prior to the placement of
material in an Ash lift, the areas should be rolled with a Caterpillar
D-4 dozer or equivalent tracked machine to create a rough surface. The
rolled surface should be sprinkled with water. Two passes of water
spraying immediately preceding the placing of an ash lift is considered
adequate. The Ash should be spread using appropriate equipment in a
manner to achieve the thicknesses specified in Subparagraph
Any tracked or pneumatic equipment may be used to spread the Ash;
however, light tracked equipment has been found to be very satisfactory
for this operation. The dumping operation should be continued in such a

Page 11 of 44

manner to provide a storage area for the surface water run-off within
the compacted Ash embankment. Immediately following the spreading of
Ash, the Ash should be compacted with three passes of pneumatic
equipment. The "Clark Michigan dozer Model 380" large frontend loader
is recommended for compaction. Any other roller can be used to compact
the Ash. Equipment speed during compaction may not be greater than 5
miles per hour. For each lift the rolling process should be
accomplished in a manner so as to overlap the adjacent compacted tread
areas of the rolled surface and thus cover the entire width of a
particular run. All additional lifts should be placed and compacted in
accordance with the aforementioned operations. The embankment must be
constructed as a series of small terraced fills. Maximum height of each
embankment must not exceed 15 feet. The face slope of the embankment
should be 2.5 horizontal to 1 vertical (2-1/2:1). The back slope of the
embankment should be (-)1.5%. The toe of each successive embankment
must be set back 60 feet from the peak of the previous embankment. The
fills are to be sloped in the manner shown on drawing A-665-C217 so as
to provide storage for the surface water runoff. The runoff is to be
contained within the ash disposal embankment itself, and the fill
slopes must be satisfactorily maintained at all times. ISG shall keep
current with placement, and ISG shall conduct its compaction operations
in accordance with engineering drawings A-665-C216/1 Ash Disposal Area
Development and Monitoring Plan, and A-665-C217 Ash Disposal Area
Sections and Details. Cover. ISG shall cover the deposited material in the
engineered fill of the Ash Disposal Area using slope cover from the
canyons located inside the Ash Disposal Area. As soon as practical
after completion of each of the terraced fills, but in no event later
than eight months after completion, the completed embankment face and
60 foot set back area must be covered with at least a two foot thick
layer of native soils (dune sand) from the canyons located inside the
Ash Disposal Area. After the canyon sand has been depleted, the stored
sand in front of the starter dike can be used. If the

Page 12 of 44

assigned sand is depleted, SRP shall either provide slope cover to the
Ash Disposal Area or compensate ISG for loading and transporting slope
cover to the Ash Disposal Area. Storm Water. ISG shall ensure proper handling of storm
runoff in the Ash Disposal Area by constructing slopes in compliance
with the engineering drawings shown on Exhibit A. The Ash must be
deposited in such a manner that storm water runoff will be contained
within the Ash embankment. The 60-foot wide benches with the 1-1/2
percent slope will contain the 100-year storm runoff falling directly
on the bench and its uphill slope. The final area must be sloped so
that all upstream runoff will be contained. Dust Control. ISG shall control and mitigate
wind-blown dust on the haul road and in the Ash Disposal Area through
the application of water and adherence to sound dust mitigation
practices. All haul roads and exposed ash fill must be sprinkled with
water so that dust will not blow from the areas. Alternately,
environmentally approved dust palliatives may be used. Erosion Control. ISG shall control erosion of the
slopes of the Ash Disposal Area by constructing slopes in compliance
with the engineering drawings shown on Exhibit A and promptly filling
any gullies and channels. Design, Engineering, Closure. ISG is not responsible
for design or engineering of any portion of the Ash Disposal Area, or
for closure of the Ash Disposal Area under state or federal law. Maintenance of Haul Road and Retention Basins. ISG
shall maintain the Ash haul road by periodically grading to the
predetermined profile established-in the following engineering

* A-665-C200 Ash Haul Road On-Site Plan A-665-C201

* Ash Haul Road On-Site ProfileA-665-C204

* Ash Haul Road Off-Site Plan & Profile

ISG shall maintain associated drainage retention basins, which have
been created to prevent any materials from being transported to natural
drainage courses by any storm or maintenance water runoff. The location
of these retention basins are shown on drawing A-665-C 1002/3 Ash Haul
Road Development and Surface Drainage Map Storm Water Pollution
Prevention Plan. SRP shall identify and provide ISG, at no cost to ISG,
aggregate necessary for ISG's maintenance activities. Crystallizer Salt. ISG shall transport Crystallizer
Salt to lined salt retention basins maintained by ISG at the Plant Site
and dispose of the Crystallizer Salt in the lined salt retention

4.4.2 Termination of Disposal Responsibility. SRP, at its sole discretion, may terminate ISG's responsibility to dispose of unsold or unprocessed Ash and Other Byproducts generated at NGS. To the extent that ISG has purchased any disposal-related equipment from SRP, SRP shall re-purchase the equipment from ISG. SRP is entitled to buy any of ISG's other disposal-related equipment. SRP is entitled to take possession of all purchased equipment immediately upon notice of termination of disposal responsibilities to ISG. SRP shall pay ISG the appraisal or market value of any equipment taken into SRP's poss
