Point Bonita Lighthouse reopened to the public in July 2021. Upon reopening, it was discovered that a transformer on one of the power poles supplying power to the lighthouse had failed and was leaking oil onto the ground. PG&E commenced initial actions by severing power to the light.
Cerrudo Services provided all labor, materials and equipment to conduct emergency environmental testing and cleanup, replace the transformer and power pole, and restore power to the lighthouse. Cerrudo tested the leaking transformer oil for PCB’s; none were detected. The existing transformer was removed from the pole and the oil recovered in sealed vessels. The pole was cut down in sections, then the base of the pole was jacked out of the ground, five feet deep. The pole sections and transformer were removed from the site.
Cerrudo utilized a helicopter to transport the new pole and transformer to the site. A detailed flight plan was submitted to and approved by the Coast Guard. The new pole was set and the transformer attached to the pole.
Cerrudo retained an archaeologist to monitor all excavation work for any artifacts of interest. None were found.
