Analysis of U.S. Oil Spillage
Total petroleum industry spillage has decreased consistently over the last 40 years. Seventy-seven percent less oil is spilling since the 1970s and 54% less since the previous decade.  The analyses in this report examine oil spillage and other oil inputs into U.S. waters from all angles – from the spills of greatest public concern, those from the oil industry’s tankers and offshore production platforms, to the spills attributable to public consumers.

Spills Prevention and Response Website
Every day, a network of tanker ships, pipelines and trucks safely delivers millions of gallons of oil and natural gas to fuel the American economy. Spills Prevention and Response is an interactive website that explores how new technologies and better training yield continual improvements as we strive to conserve valuable energy resources and protect our nation's health and environment through spill prevention. And, when spills occur, the United States employs world-leading preparedness planning and response capabilities to minimize harm to the environment.
