III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. reached the proximity of the flooded workings, av pressure associated with the drilling forced greater than anticipated quantities of water out of the hole. The quantity of water being made during drilling would have overwhelmed the capacity of themudpit at the drill site, and the operator made the decision to haul water from the drill site to Pond 12 in vacuum trucks. According to Tonya Hammond, the first water truck was brought in and began hauling Friday morning, and a second truck was used that afternoon. Both trucks were used in the hauling operation until around midnight Saturday night. About 6:30 a.m. Sunday morning, the contractor called Ms. Hammond, and reported that the pond was not holding water. She called Jim Stover, who arrived at the site azound 5:30 Sunday morning, observed the situation and collected the samples from the pond which was still dischazging. At some point during this sequence, drilling of the pilot hole and production of water from the hole had ceased, and a temporary concrete plug had been pushed into the hole. When I observed the drilling operation on the afternoon of November 19, the pilot hole was being reamed with a lazger diameter drill head, and casing was being installed. When Ireinspected the drill site at 2:30 p.m. on November 20, activity had been suspended. The drill rig and other equipmentwas still at the site but there was no one present. Tonya Hammond explained when I called the morning of November 21, that they had shut dawn temporarily until certain necessary components or supplies were obtained. She indicated that resumption of drilling was anticipated Monday, November 26, with completion of the drilling expected within a couple days thereafter. Once the drill bole is completed, installation of the final "plumbing" will entail trenching approximately 12 feet below the base of the drill pad to allow for installation of a dewatering pipe. The dewatering pipe will connect with the drill hole pipe at tbeflowline elevation, and convey minewater at a 2% slope from the point of connection, beneath the adjacent access road and into an existing culvert beneath I.70 to the outfall at the Colorado River. Additional water will likely be produced during final plumbing installation, and the operator will, have vacuum trucks on hand if necessary to haul water to Poad 8. Once the installation is completed and the system is functioning properly, the drill pad will 6e backfilled, topsoiled and seeded and final drainage controls installed. A screened S" pipe vent extension of We angled drill pipe will be exposed at the surface of the reclaimed drill site.
