Water from the site laundry, laboratory sinks, eye wash, and safety showers will flow to the process solution treatment system. 1.5.7. Diesel Storage and Distribution Storage The diesel storage tank (8.25 feet diameter by 33.5 feet long) has been sized to provide an uninterrupted two-week supply of fuel to maintain the nominal electrical load supplied by the diesel generator(s). The following storage requirements have been set as a benchmark and they will be reviewed and revised in conjunction with the requirements set by the design of the power supply network: Distribution Storage capacity – 11,000 gallons. Location – Utility Building area in accordance with NFPA 20 Paragraph 11.4.3.2. Tank design – above ground. Containment – double walled tank and bunded area. Standard of Design – UL 142. The diesel distribution system will include two (one operating and one on standby) positive displacement pumps which will supply the diesel generator and emergency diesel fire water pump. Each generator will have a day tank and fuel injector pumps (see Appendix 1-B Piping and Instrumentation Diagrams). 1.6 Parking A paved parking lot for small vehicles will be provided close to the proposed TSF Building. Stalls are designed to be perpendicular to the building, 10 feet wide and 17 feet long. Two parking stalls will be provided for persons with disabilities, and are designed to be 12 feet wide. Parking stalls for persons with disabilities will comply with applicable requirements of the American Disabilities Act (ADA). All stalls will be asphalt paved, striped, set with precast concrete bumpers, and provided with signage as required. 1.7 Security Systems – 40 CFR 270.14(b)(4) The proposed TSF will be equipped with a security and access control system. The design contemplates a security and access control system utilizing personnel Radio Frequency Identification (RFID) badges, as well as cameras and motion detectors. Security personnel will be on-site during normal working hours (i.e., 8 hours per day, 5 days per week). During periods when security personnel are not on-site, a cooperative agreement will be arranged with BGNA’s Cortez Mine to provide oversight security. The proposed TSF’s security and access control system will be monitored via off-site security personnel at the Cortez Mine.

the event of a security violation, the system is designed such that an alarm will be raised with appropriate TSF personnel and off-site Cortez Mine personnel. In order to reduce visibility of the proposed TSF, a 10-foot tall privacy berm will be constructed around the perimeter of the proposed TSF compound. Three access fences will provide additional security around the proposed TSF. The innermost barrier is a chain-link fence that will run around the perimeter of APN #005-530- 17; thus, this innermost fence will physically define the barrier that encompasses the contiguous land area for which this application is seeking a RCRA Subtitle C permit. The middle barrier will consist of the privacy berm surrounding the proposed TSF compound, with a chain link fence installed on top of the entire berm. The outermost barrier is a perimeter chain-link fence, and is the first exclusion barrier to the proposed TSF compound located external to the privacy berm. The Overall Site Plan, drawing H340940-0000-50-014-0001 (Appendix 1-A), illustrates the security barriers for the proposed TSF.
