Comment 4 While the list of chemicals and substances appears complete, DRMS required types and sizes of packaging for each designated chemical Response: Attached is the updated environmental protection plan containing the table that includes the requested information. The contents of Table 1 have been checked against the MSDS sheets to ensure consistency. Comment 5 All of the maps require signature and date of Qualified Person Response: New maps will be produced at the original scale to include signatures and dates by the qualified person. Comment 6 All environmental protection facilities require more detailed descriptions, including actual capacities, construction details, dimensions, materials, linings, and permeabilitles, and that those facilities designs are supported by engineering certifications Response: Agreed. The details demanded have been added and all of the maps in the set have been updated to include appropriate certifications and dates. The storm water map has been updated from the previous submittal to use a more accurate topographic base. As part of the Environmental Protection Plan, the storm water map is designed to stand by itself with the layout and design parameters. Per request, a portion of the design information has been copied to the body of the plan. A modification has been made on the map to the surface flow design at the west end of the ore storage area. A shallow rise is shown on the map across the west road to retain any potential surface runoff from the ore storage area inside the permit area. The shallow rise will be accompanied by a low point in the berm to the northeast (as shown) that is lower than the top of the rise. That low point will divert any excess water, not retained within the ore storage area through it, and to the north toward the ponds.
