Luzar -Neglected Mine response letter to Mine Safety dated March 14, 2008 Page 2 <br />¶ 2] As a matter of perspective the difference between "assay" quantities and "pilot" <br />quantities in large mining complexes would be of the same scale. These "pilot" chemicals <br />are much less dangerous than many "assayA chemicals. That being said both could <br />adversely affect the environment if improperly used. As an example the use of the classic <br />fire assay with acid leaching would produce high levels of vapor home contaminates while <br />the proposed process would not produce any airborne contaminates other than small <br />amounts of Hydrogen gas. <br />¶ 3) As to the storage - it is prudent to only store amounts that are to be used for a short <br />time and plan so no materials are stored over the winter. # would suggest that the. Sodium <br />Borohydride be stored in a smaller separate area within the larger storage building/area. <br />The area should have good ventilation. Dry chemical should be stored either in plastic <br />containers or on plastic wrapped pallets. All liquids should be stored in containment <br />areas such that. the v_o#ume pf liquids does not exceed 200% of the vo#ume stored and <br />that the appropriate spit# kits should be on hand. --- <br />¶ 5j Any spilled materials should be within the containment area proposed above. If a <br />spill occurs outside of this area then the materials + soil can be placed into the next <br />reaction cycle and the chemical mix adjusted, therefore the amount of waste will be small. <br />If you have any other questions oc would like me to provide addfiona# information <br />please give me a caR, <br /> <br />Joe Bowden Ph.D. <br />Senior Scientist & Partner <br />We have moved, our new address is 779 Tech Center Drive #101 -our local phone is still 247-0132 <br />
