(X RAY SILVER A11AES <br /> understands that DRMS prefers to know exactly what chemical is being used and <br /> believes that chemicals may differ between manufacturers. To address DRMS's <br /> concern, OSMI has identified several manufacturers of the critical mill chemicals <br /> and reagents for which OSMI is requesting approval. Two new columns have been <br /> added to Table 4. The first is the primary manufacturer name for each designated <br /> chemical. The second column lists an alternate manufacturer for each chemical, <br /> where available. New manufacturers not included on Table 4 will be identified, as <br /> needed, and will be forwarded to DRMS. <br /> b. In response to DRMS's comment b, Table 4 has been updated to include <br /> alternative chemical names, where applicable. <br /> c. A new column has been added to Table 4 that identifies the corrosive nature of the <br /> chemicals and their potential impacts to property. <br /> 2. Table 1/Table 5 <br /> a. Revise table 1 to show the mixing tank volume, storage tank volume and <br /> total maximum amount of each reagent chemical to be stored on site. * <br /> For those chemicals stored in various locations, such as the reagent room <br /> of the Mill Building, indicate where the various amounts may be <br /> throughout the mine site. Total amounts stored in either location shall not <br /> exceed the site wide maximum total pursuant to Rule 6.4.21(5). <br /> b. The comment sections of table 1 provided during the initial submission <br /> does not match information provided in adequacy review#1. Please revise <br /> Table 1 for the corrected volumes presented in the Adequacy Review <br /> Response in accordance with Rule 6.4.21(5). <br /> c. Pursuant to Rule 6.4.21(5) please clarify on Table 1 if the day tank is <br /> storing mixedor concentrated chemicals?Is this volume in addition to the <br /> volume stored in themixing and storage tanks? <br /> d. The containment volumes, including tank volumes are included in Table <br /> 5. Also included are the chemical amounts being stored and their package <br /> size, howeverthey are reported in pounds of dry chemicals or drums of <br /> liquid chemicals. Please revise table 5 including the volumetric <br /> conversions of dry chemicals into gallons in order to verify storage <br /> amounts and secondary containment volumes stored in each respective <br /> area pursuant to Rule 6.4.21(7)(f). <br /> Response: <br /> a. Table 1 has been revised to include the mixing tank volume, storage tank <br /> volume, packaging volume and total amount of each reagent to be stored on <br /> site, including the mill reagent room and the new Reagent Building. <br /> In general, OSMI does not plan to store chemicals in the previously <br /> permitted mill reagent room. The plan is to transport enough chemicals to <br /> 21Pa , e <br />
