Fire Detection and Control Systems Where a fire alarm system is listed in Table 1.5-3, the system will typically include smoke detectors, heat detectors, and/or manual fire pull stations. The fire protection system will also include the following elements: Audible and visual alarms. Automated controls. o All fire alarm control panels will be supplied by two independent connections from the power supply. o Control system will automatically notify appropriate emergency response. (See Appendix 6-A). Fire water level and flow detection. Instrumentation will monitor the level of water in the fire water tank as well as the flow of water. Proposed TSF Building Fire extinguishers will be installed throughout the proposed TSF (including the office, electrical room, and plant spaces). Sprinklers will be installed to service all areas of the building except the electrical room. The system will be supplied by a fire water pump and reservoir external to the proposed TSF. The Hygiene Dust Collector will be equipped with a sprinkler system and explosion panels. Utility Building Adequate freeze protection will be provided in the fire water supply tank, pumps, and piping. In addition, the following elements of fire protection are included in the design: Fire extinguishers will be installed throughout the Utility Building. Independent detection/suppression systems will be provided with the diesel generator units. A one hour fire suppression wall (Fire Wall) is designed to separate the fire water pump room as per NFPA 20 4.12.1.1.

Outdoor Areas Hydrants and hose boxes will be located around the perimeter of the proposed TSF compound allowing for emergency response access. A 100-foot fire apron will encompass the proposed TSF compound with noncombustible ground cover. Fire Water Supply and Distribution The Fire Water Tank (1542-TK-020) has a live capacity of 240,000 gallons. This capacity is based on the following assumptions: Discharge flow rate of 2,000 GPM (Includes 33% contingency on the minimum flow requirements of IFC-2012 B105.2). Minimum two hour duration as per NFPA 122-2010 13.7.2 and IFC-2012 Table B105 with fire wall separation areas. The fire water tank will be located near the Utility Building. A description of the tank is provided below: o Concrete construction coated with epoxy enamel. o Located on grade west of the Utility Building. o Membrane in foundation impermeable to water. o Rectangular configuration (81 feet long by 63 feet wide by 15 feet deep). o Freeze protection will be provided. o Equipped with two, 2,000 GPM, vertical turbine pumps (one electric and one diesel) and an electric jockey pump to maintain pressure in the fire water supply piping. 1.5.6 Effluent Treatment and Disposal Systems The Sanitary Wastewater System is designed to be separate from other regulated waste streams from the proposed TSF. This sanitary wastewater will flow into a Sanitary Wastewater Collection Tank. The Sanitary Wastewater Collection Tank will have approximately two weeks of storage. Effluent from the Sanitary Wastewater Collection Tank will be managed in accordance with applicable regulations. For preliminary design purposes, the proposed TSF contemplates the Sanitary Wastewater Collection Tank will be intermittently emptied by vacuum truck for off-site treatment and disposal (see Appendix 1-C). Other alternatives, such as an in-ground septic system, or an off-site leach field may be considered, but are beyond the scope of this application.
