Oil from the spill reached some marshes and wetland spaces Sunday. An afternoon later, it used to be transferring south towards the delicate coves round Laguna Seashore.

The oil blackened 15 miles of Orange County seashores and threatened environmentally delicate wetlands.

The American Dealer’s voyage started in Valdez, Alaska, the place it took on a shipment of crude sure for oil-storage barges on the Port of Lengthy Seashore. The tanker arrived Jan. 29 and made stops in Lengthy Seashore’s harbor to dump oil. After that, it took on a brand new, 23-million-gallon load of oil from a supertanker moored off Lengthy Seashore.

It left Lengthy Seashore at 1 p.m. on Feb. 7 and headed south for the Golden West Offshore Mooring off Huntington Seashore. There it used to be to dump 12.5 million gallons of oil to be piped to a refinery in Santa Fe Springs.
