These pit locations were historic locations that were permitted before Enduring Resources took ownership of the assets in the area. Koshak GU B1 pit location was originally permitted by Amoco in 1988 and was reclaimed before Enduring took ownership in 2017 however proper closure documentation was not submitted to ECMC by the prior operator and the record remains open in the ECMC database. This Form 15 serves to correct the ECMC database for the GPS coordinates of the historic pit location for the Koshak GU B1 pit location, ECMC location ID: 288239. During the desktop analysis, CDH reviewed operating documents from Enduring, reviewed historically filed document on the ECMC database, and viewed historic imagery from available resources including Google Earth and recently collected drone data to determine the presence or absence of previously permitted pits. For the Koshak GU B1pit location, it was determined based on the desktop review that a pit likely existed at one point and was since reclaimed by another operator prior to Enduring owning the assets.
