volume to contain 150 percent of the entire contents of the tank should a full tank rupture. The water -based and oil -based drilling mud will be contained and re- circulated from tanks within a lined (at least a 35 mil impermeable liner), bermed area also designed for 150 percent containment for any potential spills. The oil -based mud system will be fully contained, and oil - contaminated cuttings will be stored in steel drums and hauled off site for proper disposal at licensed, commercial waste facilities. All heavy equipment and service vehicles will have a supply of absorbent and other cleanup materials on hand for initial containment of spills and the Project will adhere to the Hazardous Substance Spill Plan in case of accidents. Stationary equipment will have absorbent pads or trays placed beneath them. Refueling areas will be a minimum of 300 feet from perennial and intermittent stream channels, seeps and springs, wetlands, lakes and reservoirs, stock water developments, and other water features. A Spill Prevention, Control, and Countermeasure (SPCC) Plan will be completed for the Project, as an attachment to the Exploration Plan. The Project - specific SPCC will identify structural and non - structural controls that will be put in place to prevent spills and minimize effects in the event of a spill. The spill kit will reside on site during all drilling activities. A hydrogen sulfide (H2S) contingency plan will be completed for the Project, as an attachment to the Exploration Plan. This plan will ensure that all r:g personnel are properly trained to work in a hydrogen sulfide environment and fully understand the purpose of hydrogen sulfide monitors and alarms, and the action to take when alarms visual /audible initiate. All crew members will be trained to understand the buddy system, safe briefing areas, muster stations, emergency evacuation procedures, and individual duties. The Project will conform to the Joint Agency Guidelines for Uranium Exploration Drilling Reclamation (USFS et al. 2007). Prior to exploration disturbance, background radiation level readings will be taken at each drill site. This data will be used as a reclamation standard for cleanup of each drill site. These guidelines contain conditions/ restrictions for radiation readings, drill hole abandonment, on -site drill cuttings disposal (non - diesel only), radiation reclamation, and overall reclamation (Appendix D). Water -based drill cuttings that do not meet state COGCC standards for cuttings disposal set forth in Table 910 (Appendix D) will be hauled off site to a permitted land farm facility. Solid Waste Dried, water -based cuttings will only be stored on site within a bermed, lined cuttings pad. If the chemical makeup of the dry cuttings material is below contaminant thresholds by the State of Colorado ( COGCC Rule 907d), this material could be buried in an on -site trench. Cuttings not meeting State of
