Well Pads <br /> The main pad configuration (OSR well pad) is intended to accommodate a centralized process <br /> equipment area (measuring 200 by 200 feet) and up to three OSR wells. This pad area is anticipated to <br /> be roughly triangular shaped, and current plans would result in a disturbance of approximately 3.4 acres <br /> if all of the OSR wells are eventually drilled. Contingent upon the success of the initial OSR operation, an <br /> additional 3 to 4 acres may be considered for additional testing. Total disturbance is anticipated to be <br /> less than 10 acres. NSHI intends to drill the initial OSR-1 well near the west portion of the OSR well pad. <br /> One or both of the optional OSR locations may be used if it is determined that the OSR-1 location is <br /> unsuitable or if it is determined to continue the project because of the success of the OSR-1 location. <br /> Access to the well pad would be via a short spur road extending from the northeastern corner of the <br /> triangular pad to an existing road. The DS-6 monitor well pad was permitted and bonded under <br /> Technical Revision 35 to NSI Drilling Activity Permit M1983-194. <br /> Ponds <br /> Because of the proximity of the NSI ponds, no new ponds will be constructed. The NSI process or waste <br /> ponds may be used for the disposal of any saline waste waters,when and if necessary. <br /> Power Lines <br /> Existing power lines on the lease area will not be affected by the initial research and development <br /> operations. However, the existing NSI power lines will need to be extended approximately 200 feet to <br /> bring power to the OSR well area. <br /> Storage Tanks <br /> A single temporary storage tank will be brought to the pad to store water required for the drilling of the <br /> OSR well. This storage tank will be removed after the well has been drilled and completed. Additional <br /> storage tanks will be used to store sodium bicarbonate-enriched brine produced by the dissolution of <br /> nahcolite in Phase 1 for disposal or processing in the NSI plant. Storage tanks required for the kerogen <br /> conversion phase are indicated on the equipment list(confidential). <br /> Surface Structures/Facilities <br /> Above ground shale oil storage tanks and support systems will be constructed, tested, and labelled in <br /> accordance with Underwriters Laboratories (UL) specifications for above ground storage of flammable <br /> and combustible liquids, UL-142. Skid-mounted or other portable structures will be used where <br /> appropriate. The tanks will be equipped with the option to be blanketed with an inert gas, such as <br /> nitrogen or carbon dioxide. Tanks will be installed on-site in conjunction with appropriate secondary <br /> containment (vertical dikes or other such similar and approved containment systems) to prevent spills, <br /> contain possible leaks, and protect the environment. Best management practices will be employed to <br /> ensure all surface facilities are safe, secure, and operate properly and to minimize adverse impacts to <br /> the environment. <br /> Daub&Associates, Inc.
