Plans to help restore sensitive Suisun Marsh wetlands to compensate for a 124,000-gallon diesel spill in 2004 have gained final approval. State and federal agencies completed the final environmental damage assessment and restoration plan for the Suisun Marsh oil spill, where on April 27, 2004 a pipeline owned by Kinder Morgan Energy Partners ruptured and discharged thousands of gallons of diesel fuel. The release resulted in death and injury to a variety of birds, reptiles, fish, invertebrates, and small mammals, including the salt marsh harvest mouse - an endangered species.
