5.0 Chemicals and Materials Handling Plan • • 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 Barium Chloride used in this treatment process does not have any known toxic or acid-forming potential and does not cause any known environmental hazard in the quantities used and stored on site. Care must be observed when adding the 50% Ferric Sulfate solution to the reagent tank as this solution has a pH of about 1.0 prior to dilution and could cause acid burns if unprotected skin is exposed. The reportable quantity for spilled Ferric Sulfate is 1,000 pounds. All reagents will be stored and used within the trailer and a monthly inventory of reagents used and in storage will be maintained. During periods of inactivity, the trailer will be locked to prevent unauthorized entry or the potential of an environmental release of chemicals. During periods of 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 reaction tanks are both supplied with secondary containment. The water treatment plant area will be sloped toward the Sediment 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 instructed 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. Initially a diesel generator will be used to supply power to the treatment plant. It 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 tank will be checked with a measuring stick prior to dispensing fuel to determine the approximate volume of fuel required to fill the tank. The fuel will be dispensed manually and the plant operator or other designated personnel will be present at all times during refueling. Any spillage will be cleaned up with absorbent material and placed into an open top drum for later disposal. 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. A vendor will recycle used oil. 17
