An estimated 700 gallons of diesel fuel spilled at the Maui Space Surveillance Complex located at the summit of Haleakalā, the US Pacific Air Forces reported.
Authorities pointed toward a mechanical issue in which a diesel fuel pump for an onsite backup generator failed to shut off during the night on Sunday, Jan. 29. The following morning at 8 a.m., site maintenance personnel identified that the pump failed to shut off and immediately deactivated the transfer pump.
