ISG shall provide all labor, equipment, logistics, transportation and business coordination to market and sell Ash, and products made from Ash, as set forth in this Agreement. 4.3.1.2 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 NGS. 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: 4.4.1.1 Transportation. ISG shall transport Ash and Other Byproducts, other than Crystallizer Salt, to the NGS Ash Disposal Area. 4.4.1.2 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. 4.4.1.3 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. 4.4.1.4 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 4.4.1.2. 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. 4.4.1.5 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. 4.4.1.6 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. 4.4.1.7 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. 4.4.1.8 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. 4.4.1.9 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. 4.4.1.10 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 drawings: * A-665-C200 Ash Haul Road On-Site Plan A-665-C201 * Ash Haul Road On-Site ProfileA-665-C204 * Ash Haul Road Sections and Details Sheet 1A-665-C101 * Location and Vicinity Plan A-665-C202 Page 13 of 44 * 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. 4.4.1.11 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 basins. 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 possession, provided that the amount paid may never exceed the original cost to ISG plus the cost of any capital additions. 4.5 Facilities and Equipment. 4.5.1 Responsibility for ISG Facilities and Equipment: Loss, Damage Caused by Operation. ISG assumes full responsibility for the care, custody, and control of its facilities and equipment.

All damage caused by the operation of ISG's equipment or facilities to the work and property of ethers, whether public or private, must be repaired at ISG's expense to the reasonable satisfaction and approval of SRP. Page 14 of 44 4.5.2 Necessary Facilities and Equipment. SRP grants to ISG, its agents, employees, and subcontractors, access to and use of existing NGS facilities used in management of Ash and Other Byproducts, including scales, silos, loading facilities, and offices; and grants them ingress and egress to NGS via designated haul roads that will bear the weight of all vehicles reasonably required to perform ISG's services. SRP shall provide parking for ISG's employees in designated parking lots. ISG shall procure or provide, and maintain, the following facilities and equipment, at its cost: * Two scales at the SRP loading site capable of weighing all trucks used by ISG to transport Ash and Other Byproducts from NGS. * All equipment and tools necessary to load and transport Ash and Other Byproducts to ISG's Ash processing facilities, to end consumers, and to the Ash Disposal Area. * All equipment or tools necessary to dispose of Ash and Other Byproducts in the Ash Disposal Area, or, with respect to Crystallizer Salt, in lined salt retention basins dedicated for that purpose. * All equipment and tools necessary to maintain those NGS facilities identified in Subparagraph 4.6.3. * A rail load-out terminal in Nevada or Arizona capable of loading out 10 to 15 rail cars per day. 4.5.3 Equipment Lease. ISG shall lease from SRP four Caterpillar model 773B haul trucks under the equipment lease attached to this Agreement as Exhibit C, which lease expires on October 14, 2005. Upon the expiration of this lease, ISG shall continue to lease four Ash haul trucks from SRP under terms and conditions to be negotiated by the parties prior to expiration of the current lease. After October 14, 2005, the Ash haul trucks shall be replaced as reasonably necessary for the efficient management of Ash and Other Byproducts generated at NGS. Replacement of any trucks shall be at a cost and specification acceptable to both SRP and ISG, with the lease amount calculated based upon SRP's weighted average cost of capital. Page 15 of 44 4.5.4 Maintenance of Scales. ISG shall arrange for calibration of the existing SRP scale and all other scales ISG installs at least twice annually, and keep the scales sealed and in good operating condition. The Parties shall share the cost of calibration equally. The scales must be calibrated to Arizona State "legal for trade" tolerance. Either Party, at its expense, may calibrate the weight scales more frequently than twice annually. In the event that any scale used to weigh Ash falls outside of the abovereferenced tolerance, the Parties agree to meet and reconcile the discrepancy for the applicable period, and to adjust the financial impact of the discrepancy. The meeting and reconciliation of the discrepancy must be conducted under the dispute resolution provisions provided for in this Agreement. ISG shall pay for any scale re-certification resulting from a broken seal or maintenance. 4.5.5 Maintenance Facilities for ISG Equipment.
