• 5.0 Chemicals and Materials Handling The proposed water treatment facility will house all the reagents necessary for this operation. The trailer will act as the storage facility as well as the mixing and reagent usage location for this operation. The chemicals /reagents in use for this treatment process have no known toxic or acid- formingpotential and do not cause any known environmental hazard in the quantities used and stored on site. All reagents will be stored and used within the trailer and a monthly inventory of reagents used and in storage will be maintained. During off shift periods, the trailer will be locked to prevent unauthorized entry or the potential of an environmental release of chemicals. During periods of treatment system inactivity the treatment plant tanks will be drained and emptied for maintenance reasons and to prevent an uncontrolled release of chemicals or untreated water. The water treatment plant floor drain is connected to a 200-gallon secondary containment tank. This tank will have an emergency overflow pipe to the untreated water storage pond. In the unlikely event that a tank or pipe fails, any solutions released from the trailer would be directed toward the pond, where containment and clean-up can be accomplished. • All handling and mixing of reagents will be performed by trained plant operators. The operators will be provided with the necessary PPE and will be instnrcted on the proper handling, operating, cleanup, and reporting procedures for these reagents. The operators will also be trained on potential chemical reactions and safety hazards. Electrical power will be supplied by either line power or by a diesel generator. The diesel generator used to supply power to the treatment plant will need to be fueled and serviced on a routine basis. During fueling, the generator will be shut off and No. 2 diesel fuel will be transferred from a fuel truck or pick-up mounted tank using a hose and dispenser. The fuel will be dispensed manually and the plant operator or other designated personnel will be pmsent at all times during refueling. Any spillage will be reported and cleaned up in accordance with the procedures detailed in the Material Containment and Spill Prevention Control and Countermeasure Plan (MCP / SPCC). A drip pan will be used to contain oil removed during maintenance activities; this oil will then be transferred to a designated container or used oil tank. Used oil will be recycled by a vendor. A detailed, site-specific chemical and materiai handling and containment plea will be prepared prior to plant startup. This plan will include proper storage and handling methods for the various chemical products, inspection procedures and check lists, preventive maintenance requirements, personnel training, emergency response procedures in the event of a spill or release, and spill reporting requirements. • 15
