a termination of water monitoring of the thirteen sites. Baseline data had been collected at all of the sites and monitoring will be initiated if future mining operations continue. Technical Revision No. 108 was received on August 22, 2016, deemed complete on August 31, 2016, and approved on October 11, 2016. The revision proposed to remove the permitted gob vent boreholes (GVB) 19A, 19B, 19C and the disturbances associated with the operation and reclamation of the construction of the GVBs. GVB 19A, 19B and 19C were not constructed and no disturbances associated with the GVBs was conducted. The removal of the GVBs will constitute a reduction of the bond liability associated with the GVBs. Technical Revision No. 109 was received on September 12, 2016, deemed complete on September 14, 2016, and approved on September 29, 2016. The revision proposed to revise the permit to include a revised expansion plan of Pond J. An expansion of Pond J to the east was proposed and approved under TR -84. TR -109 proposed to expand Pond J to the west rather than the east. The proposal did not include any new disturbance area. Technical Revision No. 110 was received on November 16, 2016, deemed complete on November 23, 2016, and withdrawn on January 6, 2017. The revision proposed to construct a gasification plant within the area of the clean coal stockpile pad. The proposed gasification plant facilities would have been used to convert coal mine waste to a synthetic gas. Technical Revision No. 111 was received on December 9, 2016, deemed complete on December 15, 2016, and withdrawn on February 13, 2017. The revision proposed to revise the monitoring frequency of the vibrating wire piezometers and the inclinometers located within Gob Pile #2 and Gob Pile #4 and the Bowie No. 2 Mine from four times a year to two times a year. The revised monitoring frequency was based upon the temporary cessation status of the mine and the significant reduction in coal processing waste placed on the piles. Technical Revision No. 112 was received on May 16, 2017, deemed complete on May 26, 2017, and withdrawn on July 31, 2017. The revision proposed to allow Oxbow Mining, LLC (Oxbow) to use the TC - 03 -01 pad to support Oxbow's coal methane recovery project. BRL and Oxbow entered an agreement in 2015 which allows Oxbow to extract coal bed methane from the existing B and D seam workings of the Bowie No. 2 Mine. The TC -03-01 pad has not yet been reclaimed by BRL. Oxbow plans to use the pad to drill up to four seal removal holes into the seal of the 1 west mains in the Bowie No. 2 Mine. The seal removal holes will allow for pressure equalization across the seals and enhance coal bed methane recovery. The application proposes no new surface disturbance. Technical Revision No. 113 was received on June 26, 2017, deemed complete on June 28, 2017, and approved on July 24, 2017. The revision proposed to revise the drainage configuration on the top of Gob Pile #4. The proposed configuration would become the final configuration once approved. The revision proposes to change the location and drainage area of ditch D-7, and the revision proposes the creation of a new ditch, F20. Technical Revision No. 114 was received on August 29, 2017, deemed complete on September 5, 2017, and the Revision is currently in the adequacy process with the Division.
