AUGUST 18, 2015 — If you, like many, believe oil shouldn't just be spilled without consequence into the ocean, then you, like us, should be grateful for a very important U.S. law known as the Oil Pollution Act of 1990. Congress passed this legislation and President George H.W. Bush signed it into law 25 years ago on August 18, 1990, which was the summer after the tanker Exxon Valdez hit ground in Prince William Sound, Alaska.
