'Ihe investigation that began on April 3 was limite3 to the disturbed area around <br />• the lobe/fueling facility. A backhce was used to dig pits to determine the <br />extent of diesel migration. the investigation indicated that diesel had migrated <br />further than anticipated, and as such approval is needed to allow digging of <br />backhce pits in the undisturbed area adjacent to the facility. <br />Prior to digging the backhce pit the topsoil was dozed to the side of the area. <br />Once the topsoil is removed the pit will be dug aryl the excavated material will <br />be placed adjacent to the pit. After the pit has been con~leted it will either <br />be backfilled or left open for further monitoring. The area will be reclaimed <br />upon completion of the project. <br />• <br />• <br />ME2 91-64 Permit Renewal 780-30-2 (c) Revised 01/16/91 <br />
