On April 27, 2004, an underground Kinder Morgan 14" (35.6 cm) pipeline ruptured at Suisun Marsh in Solano County, California, spilling over 120,000 US gallons (454 250 L) of diesel fuel directly into the marsh. The cause was pipe corrosion. The company failed to notify authorities about the spill for 18 hours, another safety violation for which it was later cited. Kinder Morgan was fined $5.3 million for the spill, and agreed to enhance spill prevention, response and reporting practices. The company had 44 spills in 31 months, indicating "widespread failure to adequately detect and address the effects of outside force damage and corrosion," according to an order issued in August 2005 by the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA).
