ResponseSpill and CountermeasuresNEWMONT •r the Cresson Project •' Sustainability& ExternalRelations 4 DESCRIPTIONS OF OIL AND CHEMICAL STORAGE FACILITIES AT CC&V OPERATIONS Individual chemical storage and use areas within the Cresson Project are described in this section.The descriptions of bulk storage areas are organized by chemical category and location. Individual oil storage facilities descriptions follow the detailed requirements of 40 CFR Part 112 in terms of quantity stored/used, potential spill volume,spill prevention and control procedures,spill countermeasures,security,visual inspections, integrity testing,and conformance with other laws or regulations. Facility Tables provides an inventory of oil containing products stored and used at the Cresson Project. Individual process reagents, explosive agents, refinery wastes, lime, and laboratory chemical descriptions follow a slightly different outline for facility descriptions, although many of the same elements as for oil products do apply. The categories of chemicals described in the following sections include: • Petroleum Products; • Ammonium Nitrate, Emulsion,and ANFO; • Process Reagents for Beneficiation; • Lime;and • Laboratory Chemicals. Petroleum-Based Products(fuel,lubricants)and Antifreeze Fuels,oils, and antifreeze are stored in tanks,totes, and drums in several locations on the property. Refer to Figures 3-9 for referenced locations of bulk storage areas. Ironclad Warehouse and New Truck Shop(NTS)(Figure 3 and Table 3a and Table 3b)—The Ironclad Warehouse stores used oil, lubricants, and hydraulic oil are stored in aboveground storage tanks(ASTs) in an interior area constructed to contain the products; antifreeze is stored in an above ground tank just outside the oil storage room; used oil and used antifreeze are stored in totes or drums on the shop floor; and propane are stored in ASTs outside the building.The NTS stores lubricants, hydraulic oil,antifreeze,and used oil are stored in ASTs in an interior area constructed to contain the products;small quantities of used oil, used antifreeze,and varieties of petroleum-based lubricants are stored in totes, large drip pans or drums, on the Truck Shop floor. Midway Fuel Farm(MFF)(Figure 4 and Table 4)-diesel fuel,gasoline,fuel additives, motor oil, antifreeze,and hydraulic oils are stored in ASTs within a lined secondary containment area.There is also a 1,000 gallon propane tank located to the north of the MFF. Crusher Storage Areas(Primary and Secondary)(Figure 5 and Table 5)—hydraulic oil and lubricants are stored either on a grate covered metal box over a concrete floor or within other secondary containment. Adsorption Desorption Recovery(ADR-1) Plant(Figure 6 and Table 6a and Table 6b)—diesel fuel is stored in ASTs outside to the east of the ADR-1 Plant. Process reagents are stored inside the building in multiple ASTs,varying in storage capacity. Process Solution Enhancement System(PSES) Facility(Figure 7 and Table 7)—Chemical (water treatment) reagents include coagulants,flocculants, polymers, diatomaceous earth, and magnetite.The PSES uses chemicals and reagents to treat and condition process water. High Grade Mill(HGM) Building(Figure 8 and Table 8a and Table 8b)—diesel fuel and new and used grease and oils are stored inside the HGM Building in ASTs and steel drums. Lime is collected west of the HGM building and process chemicals are stored inside in varying sizes of ASTs. Squaw Gulch Adsorption Desorption Recovery(ADR-2) Facility(Figure 9 and Table 9)—generators or located on the northwest side of the ADR-2 building that contain diesel fuel. Inside the Facility, multiple process chemicals are stored in varying sizes of ASTs. ------- ---_. .. -_-w-- -------- ---- - - ----- -------- ------I--- ----- --------- :- _ _ .
