The project work will include excavating the burning coal refuse fire, quenching the burning material with a mix of water and Silv-Ex Type A firefighting foam, blending with non-carbonaceous overburden at a ratio of 1-part non-carbonaceous material to 1 part burning coal refuse. Then the blended material will be backfilled, and the site will be prepared for final grading. Final grading will be done in a future project and is not included in this bid. For this project, the excavated and quenched materials shall be backfilled back into the same cut that they were excavated from. Materials will be considered burning when they show a temperature greater than or equal to ninety degrees Fahrenheit (90o F). The refuse pile is approximately thirty-five feet (35 ft) deep, three hundred and sixty (360 ft) long, east to west (E/W), and approximately one hundred and thirty feet (130 ft) wide, north to south (N/S). The refuse pile accounts for approximately eighty-two thousand and four hundred cubic yards (82,400 cy) of material blending this with another eighty-two thousand four hundred cubic yards (82,400 cy) resulting in a total of 164,800 cubic yards of material needing to be moved. Regardless, of the coal volume, the entire refuse pile (identified as the Mesa on the attached maps) will be excavated, blended, and backfilled.
