Ona oil dnins and other conteittus ere emptied, <br />they will be removed from the site to en approved dump or reprocessing facility. <br />There is a potential far a spill when fueling vehicles, however, the amount of a spill <br />would be small. Any leakage of oil or other fluids from mobile equipment or machinery <br />would involve small amounds and can be cleaned up by removing the affected soil. <br />c.
