EVAPORATION POND 1. The designated operator/lessee will be required to pump and haul waste water from the evaporation ponds to an approved disposal site if the evaporation ponds reach or exceed their design capacity, unless otherwise approved in writing by the authorized officer. 2. The liners of the evaporation ponds will be underlain by a minimum of 4 inches of suitable soil material containing at least 95 percent material passing the No. 10 sieve (ASTM E-11 specifications) or other approved method. 3. A watertight catchment basin or other approved method will be employed at the outlet of the leak detection system on each of the evaporation ponds to contain any leaked fluids. 4. A buffer zone of 15 feet of undisturbed vegetation will be maintained between the toe of the fill slope on the east side of the evaporation ponds and the edge of the adjacent major drainage. 5. Evaporation pond Liner integrity will be maintained during periodic removal of solids. If the liner is damaged during solids removal operations, the Liner shall be repaired to the satisfaction of the authorized officer. WELL DRILLING, COMPLETION AND ABANDONMENT 1. The annulus between the well bore and the 8 5/8-inch well casing will be filled with cement from the shoe of the 8 5/8-inch casing upward for 250 feet. Prior to horizontal drilling a Cement Evaluation Tool (CET) or equivalent log shall be run across this interval plus 100 feet above. 2. A "Notice of Intent to Abandon" will be submitted by the designated operator/lessee to the authorized officer before abandonment of any well developed within this project. The notice will contain an "as-built" diagram of the well and will describe any changes from the approved abandonment/plugging procedures. The authorized officer will review and approve or approve with modifications the notice within 15 calendar days of receipt. No special form for this notice is required. As a minimum, the following plugs will be required: 1) a steel bridge plug will be placed at the base of the production casing; 2) 100 feet of cement will be placed above this steel bridge plug; 3) a cement plug will be placed 20 feet above the Mahogany Zone down through to 120 feet into the Mahogany Zone and must be tagged to insure placement; and 4) 65 feet of cement will be placed at the surface. The intervals between the cement plugs will be filled with 9 pound/gallon or heavier mud. Other cement plugs or revised plugging procedures may be required, based on analysis of the cement evaluation logs. An appropriate surface hole location marker will be installed at grade. ;, 6
