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, air 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 overwhehned the capacity of themudpit at the drill site, and the operator made the decision to Gaul water from the drill site to Pond 12 in vacuum trucks. According to Tonya Hammond, the fast water truck was brought in and began hauling Friday morning, and a second truck was used that aftemoon. 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 around 8:30 Sunday morning, observed the situation and collected the samples from Ute 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 aftemoon of November 19, ffie 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 down 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 hole 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 theflowline elevation, and convey minewater at a 2% slope from the point of connection, beneath the adjacent access road and into as existing culvert beneath I-70 to the outfall at the Colorado River. Additional water will likely be produced during Erna! plumbing installation, and the operator will have vacuum trucks on hand if necessary to haul water to Pond 8. Once the installation is completed and the system is functioning properly, the drill pad will be backfilled, topsoiled and seeded and final drainage controls installed. A screened 8" pipe vent extension of the angled drill pipe will be exposed at the surface of the reclaimed drill site.
