August 18, 2011 C-1981-018/Deserado Mine JRS GENERAL MINE PLAN COMPLANCE: -The operator was currently mining in longwall panel LWB-11. They are approximately 90%complete with the panel. The anticipated completion date for this panel is the end of October 2011. They will then be moving the longwall and begin mining longwall panel LWB-12. They operator has also completed the development work for the headgate for longwall panel LWB-12. This information was compared with the currently approved Map 120 = B-Mine Plan and found to be in compliance. OTHER(Possible Illegal Dumping Incident): At approximately 16:00 Brock Bowles and I received a message that there was a report of a possible illegal dumping incident at the Deserado Mine. I called Sandy Brown in the Denver office and she read and forwarded the incident report,taken by CDPHE. The report alleged that a containment structure around a diesel tank, antifreeze tank and other tanks had filled with rainwater and spills and was completely full. The allegation then stated that the water/fueUantifreeze mixture was put into a water trailer and ultimately dumped into a hole"up on a hill... into a hole dug between the silos"and"across CR 65 and dumped by the place where they load trains,near a refuge(sic)area"and that"a naturally occurring pond `in the back' may have been impacted". The report alleged that there was approximately 2,000 gallons that was approximately 80%rainwater and 20%diesel fuel and antifreeze. Brock and I returned to the site and arrived there at approximately 16:30. We contacted Scott Wanstedt and told him about the allegation of illegal dumping. He immediately took us to his supervisor,Jeff Dubert (the head of engineering)and Bill Lepro, an engineer at the site who does all required inspections and certifications. We told Jeff, Bill and Scott about the allegation of illegal dumping at that point. Jeff, Scott and Bill(BME)all agreed that there was"some"water and a small amount of diesel fuel, Lingo Sulfonate and possibly shield oil mixed with water in the tank enclosure at the D-portal tank farm. They stated that the diesel fuel(mixed with water)was removed from the enclosure and put in the waste oil storage drums. They said that the mixture was mostly water. They said that the remaining water was placed into a water tanker (trailer)and spread on the refuse pile. They stated that this water contained Lingo Sulfonate, which they use as dust suppression on their haul road. They said that they removed the remaining sludge material and moved it to a sump by the coal silos until it dried some then transported that to the refuse piles(RP-5a) for disposal. We then informed them that we would need to do a site visit to investigate the allegations. They said"fine, go where ever you need". We then got into the truck with Scott and started our field investigation. We first went to the coal silo area,where half of the material was allegedly buried. These silos are on a"hill" above the facilities area(on the coal prep plant bench). We did see the sump area that BME discussed to the northwest of the coal silos. While there was some wetness present,there was no diesel or oily appearance or smell evident at the sump location. We then walked around the coal silos and prep plant bench area and there were no recent disturbance areas that would have been indicative of recent excavation. There is no area"between"the silos, as they are connected by cement,with a cage and ladder on either side,to access the top of the silos. We found no evidence at or around the coal silos that indicated that any diesel fuel had been dumped buried there.
