f i I Comment 2: Please commit to making the spill reports available on-site for the Division to review during site inspections. These reports should include the information from the samples taken of the spilled material and the soil matrix. i Response 2: Newmont commits to making spill reports, specific to the unlined haul road, available to Division representatives, including sampling results for both the spilled and surrounding material. Comment 3: Please clarify what quantity of spilled material will initiate the Spill Response Plan and clean up. Response 3: Any material spillage will initiate the SPCC. Comment 4: Under the Spill Response Plan header of TR-83, the Operator states that decontamination will be conducted on the SGVLF using a water truck cannon to spray out the beds and buckets of contaminated equipment. Please verify that this decontamination activity will only occur over the liner system. Response 4: Newmont verifies decontamination activity will only occur over the liner system. Comment S: During the August 20, 2016 meeting between CC&V and the Division, it became known that when haul trucks enter the SGVLF, they drive over ore that has yet to be leached so there is no contact between the sodium cyanide solution and the haul truck tires. Additionally, if haul trucks must pass over leached material, a three foot lift of fresh material would be brought in prior to entering that area. Please commit that all haul truck traffic will occur on top of at least three feet of fresh, un-leached material at all times when in the SGVLF. Response 5: Newmont commits that all haul truck traffic will occur on top of at least three feet of fresh, un-leached material at all times when in the SGVLF. Comment 6: Under the SGVLF Sequencing and Schedule header of TR-83, the Operator states that Phase II is planned to be completed in Q3 of 2020 and the liner will completely tie-in to Phase I liner and allow haul truck traffic to travel over liner when on the SGVLFfootprint. Please commit to ensuring that all haul truck traffic will occur over a liner system when Phase II is completed. Note, this will add a section of the haul road, approximately 1,200 feet in length, between the LOB and the SGVLFfootprint. This new liner will need to be tied into or drain into the SGVLF, AGVLF, and HGM liners. Response 6: Newmont commits to ensuring all haul truck traffic travelling interior from the edge of the SGVLF liner system which includes Phase I and Phase II,will occur over a liner system when Phase II of SGVLF is completed. Newmont does not intend to line the section of haul road from the LOB to the edge of the SGVLF liner system.
