On May 10, 2017, CC&V received the Adequacy Review comment letter <br /> from the Division of Reclamation, Mining and Safety(DRMS). <br /> General Comments. <br /> A. The submittal included a six page cover letter with no page numbers. This makes referencing <br /> specific text more challenging and less specific. Please number pages (the cover page may be <br /> excluded) in fitture submittals. <br /> CC&V Response: Page numbers have been added to the response. <br /> B. The Division's primary concerns with TR-90 as proposed are related to materials handling, spill <br /> prevention, and controlling mercury (Hg) exposure to personnel and the environment. During the <br /> May 1, 2017 meeting, the Division expressed these concerns. Research by the Division identified <br /> a 1997 draft document written by the Mine Safety and Health Administration (MSHA) entitled <br /> "Controlling Mercury Hazards in Gold Mining: A Best many more) and how to best mitigate <br /> these hazards. Comments below reference this document. <br /> C. Spill cleanup and disposal were discussed during the May 1, 2017 meeting. The Division <br /> indicated at the time that spills need to be cleaned zip using powders designed to form an <br /> amalgam and not methods typically used for other "liquid"spill cleanups. Please formalize your <br /> spill cleanup plan and describe what kit materials will be kept on hand in the AGADR. <br /> 1 <br />
