 So the fix, and I'm making these numbers up, the fix that they were going to make, the temporary thing that Chevron wanted to do probably cost around $10 million. To revamp the whole refinery would have cost billions of dollars. So Chevron brought it to court. It ended up in the Supreme Court. The Supreme Court back then said- In the 80s. Yep. The Supreme Court said back then, look, any rule not promulgated by Congress can be interpreted and promulgated by the agencies. Right.
