The Murphy Oil USA refinery spill was an oil spill that resulted from the failure of a storage tank at the Murphy Oil USA petroleum refinery in the residential areas of Chalmette and Meraux, Louisiana, United States, on August 30, 2005, the day after Hurricane Katrina made landfall on the U.S. Gulf Coast.

On August 29, 2005, the storm surge from the hurricane caused massive failure in the levees along the Mississippi River-Gulf Outlet Canal, inundating St. Bernard Parish with 4 to 14 feet (1.2 to 4.3 m) of water. The Murphy Oil refinery was flooded with 6 to 18 feet (1.8 to 5.5 m) of water, and a 250,000-barrel (40,000 m3) above-ground storage tank at the refinery was dislodged from its moorings and damaged in the flooding. At the time, the tank contained approximately 65,000 barrels (10,300 m3) of mixed crude oil; a breach in the tank's side wall released up to 25,110 barrels (1,055,000 US gal), though the pressure from the floodwaters kept the oil inside of the tank until the waters had receded to about 4 feet (1.2 m), five days after the storm had passed.

As the oil was released, it mixed with the floodwaters and flowed from east to west. The spoiled water impacted approximately 1,700 homes in adjacent residential neighborhoods of Chalmette, over an area of about 1 square mile (2.6 km2). Several canals were also impacted, including the 20 Arpent Canal, the 40 Arpent Canal, the Meraux Canal, the Corinne Canal, the DeLaRonde Canal, and various unnamed interceptor canals.

According to the U.S. Coast Guard, there were about 44 oil spills in the area affected by Hurricane Katrina, though most occurred in areas of Plaquemines Parish which do not have large populations. The Murphy Oil USA spill was the exception.

Major industries in St. Bernard Parish, including the two oil refineries, had disaster mitigations plans that were filed with the local government. However, the local government lost most of its files in the flood that followed the levee failure.

Employees of oil refineries in the disaster area have stated on online forums that their refineries filled tanks with water in order to prevent them from floating away.[ citation needed ] However, typical pre-Katrina industry standards on the Gulf Coast were based on a heavy rain event, and did not anticipate a full inundation of water around the storage tanks.

Another refinery employee commented that these large oil storage tanks are sometimes purposely floated in order to move them.[ citation needed ] The containment levees around the tank are generally filled with water and tanks are moved in this way around tank farms. This is done on a planned basis with all oil removed from the tank being moved.

Lake Pontchartrain is an estuary located in southeastern Louisiana in the United States. It covers an area of 630 square miles (1,600 km2) with an average depth of 12 to 14 feet. Some shipping channels are kept deeper through dredging. It is roughly oval in shape, about 40 miles (64 km) from west to east and 24 miles (39 km) from south to north.

The Mississippi River–Gulf Outlet Canal is a 76 mi (122 km) channel constructed by the United States Army Corps of Engineers at the direction of Congress in the mid-20th century that provided a shorter route between the Gulf of Mexico and New Orleans' inner harbor Industrial Canal via the Intracoastal Waterway. In 2005, the MRGO channeled Hurricane Katrina's storm surge into the heart of Greater New Orleans, contributing significantly to the subsequent multiple engineering failures experienced by the region's hurricane protection network. In the aftermath the channel was closed. A permanent storm surge barrier was constructed in the MRGO in 2009, and the channel has been closed to maritime shipping.

<span class="mw-page-title-main">Effects of Hurricane Katrina in New Orleans</span>

As the center of Hurricane Katrina passed southeast of New Orleans on August 29, 2005, winds downtown were in the Category 1 range with frequent intense gusts. The storm surge caused approximately 23 breaches in the drainage canal and navigational canal levees and flood walls. As mandated in the Flood Control Act of 1965, responsibility for the design and construction of the city's levees belongs to the United States Army Corps of Engineers and responsibility for their maintenance belongs to the Orleans Levee Board. The failures of levees and flood walls during Katrina are considered by experts to be the worst engineering disaster in the history of the United States. By August 31, 2005, 80% of New Orleans was flooded, with some parts under 15 feet (4.6 m) of water. The famous French Quarter and Garden District escaped flooding because those areas are above sea level. The major breaches included the 17th Street Canal levee, the Industrial Canal levee, and the London Avenue Canal flood wall. These breaches caused the majority of the flooding, according to a June 2007 report by the American Society of Civil Engineers. The flood disaster halted oil production and refining which increased oil prices worldwide.

On Monday, August 29, 2005, there were over 50 failures of the levees and flood walls protecting New Orleans, Louisiana, and its suburbs following passage of Hurricane Katrina. The failures caused flooding in 80% of New Orleans and all of St. Bernard Parish. In New Orleans alone, 134,000 housing units — 70% of all occupied units — suffered damage from Hurricane Katrina and the subsequent flooding.

Drainage in New Orleans, Louisiana, has been a major concern since the founding of the city in the early 18th century, remaining an important factor in the history of New Orleans today. The central portion of metropolitan New Orleans is fairly unusual in that it is almost completely surrounded by water: Lake Pontchartrain to the north, Lake Borgne to the east, wetlands to the east and west, and the Mississippi River to the south. Half of the land area between these bodies of water is at or below sea level, and no longer has a natural outlet for flowing surface water. As such, virtually all rainfall occurring within this area must be removed through either evapotranspiration or pumping. Thus, flood threats to metropolitan New Orleans include the Mississippi River, Lake Pontchartrain, canals throughout the city, and natural rainfall. Artificial levees have been built to keep out rising river and lake waters but have had the negative effect of keeping rainfall in, and have failed on numerous occasions.
