Minesite Inspection Narrative Page 3 of All drainage control culverts were open and functional. One culvert located on the road, crossing the east collection ditch at the material storage area was not shown on the map from the Albuquerque Field Office permit package. Mr. Ranney informed me he was sure that this culvert was approved, was on the most recent maps and he would contact the consultant and ask he provide me a copy of this map. I told Mr. Ranney that would wait until returning to Albuquerque before issuing a Ten Day Notice to allow for the map to be send to me as the consultant was not available during the inspection. The consultant, Darry Ferguson contacted me by phone after my return to Albuquerque and faxed me a copy of the section of the map showing the culvert. Additionally he said he would a copy of the actual map. As material has been provided showing the culvert a TDN will not be issued. There has been no recent activity at what is referred to on permit maps as the fill area. Also there has been no recent activity on the two areas mined on each side of the watershed above the fill. Sediment had built up and almost blocked the east collection channel below the mining bench on the east side of the fill area. This buildup was cleaned before the inspection was completed and as the flow had remained under control no enforcement action is warranted. Water was flowing in this channel during the inspection. While inspecting this channel I noticed yellowish-orange staining of rocks in this channel and the channel itself that is indicative of acid mine drainage. The water flowing in the channel was coming from seeps on the mining bench above this channel. It appeared that this water was seeping off an exposed coal seam on the bench. During the morning on March 23 DMG collected and tested with a pH meter water from the channel above where the cleaning had been done and off the bench. The sample from channel showed a Ph of 7.3 and the sample from the bench showed a pH of 5.44. This water was not leaving the site and in fact was not reaching the pond so no enforcement action is warranted at this time. However it was apparent that acid forming materials are present on this site and the permit for this should be revised to include any needed mitigation for acid mine drainage. It is my understanding that the areas where gravel mining is ongoing will not be mined for coal so removal of this area from the permit should be considered to avoid confusion about liabilty for reclamation in the future.
