Outdoor Areas<br />

Hydrants and hose boxes will be located around the perimeter of the proposed TSF<br />

compound allowing for emergency response access.<br />

A 100-foot fire apron will encompass the proposed TSF compound with noncombustible<br />

ground cover.<br />

Fire Water Supply and Distribution<br />

The Fire Water Tank (1542-TK-020) has a live capacity of 240,000 gallons. This capacity is<br />

based on the following assumptions:<br />

Discharge flow rate of 2,000 GPM (Includes 33% contingency on the minimum flow<br />

requirements of IFC-2012 B105.2).<br />

Minimum two hour duration as per NFPA 122-2010 13.7.2 and IFC-2012 Table B105<br />

with fire wall separation areas.<br />

The fire water tank will be located near the Utility Building. A description of the tank<br />

is provided below:<br />

o Concrete construction coated with epoxy enamel.<br />

o Located on grade west of the Utility Building.<br />

o Membrane in foundation impermeable to water.<br />

o Rectangular configuration (81 feet long by 63 feet wide by 15 feet deep).<br />

o Freeze protection will be provided.<br />

o Equipped with two, 2,000 GPM, vertical turbine pumps (one electric and one<br />

diesel) and an electric jockey pump to maintain pressure in the fire water<br />

supply piping.<br />

1.5.6 Effluent Treatment and Disposal Systems<br />

The Sanitary Wastewater System is designed to be separate from other regulated waste streams<br />

from the proposed TSF. This sanitary wastewater will flow into a Sanitary Wastewater<br />

Collection Tank. The Sanitary Wastewater Collection Tank will have approximately two weeks<br />

of storage.<br />

Effluent from the Sanitary Wastewater Collection Tank will be managed in accordance with<br />

applicable regulations. For preliminary design purposes, the proposed TSF contemplates the<br />

Sanitary Wastewater Collection Tank will be intermittently emptied by vacuum truck for off-site<br />

treatment and disposal (see Appendix 1-C). Other alternatives, such as an in-ground septic<br />

system, or an off-site leach field may be considered, but are beyond the scope of this application.<br />
