Generally if the "official" claims are that 90000 gallons spilled you can multiply by 10 to get a more accurate amount.
Using the metaphor that Industrial forms of energy truly rape the earth, the constancy of these deadly spills and the way they're tolerated (since "lawmakers" and politicians are beholden to the Oil cartels) is eerily reminiscent of the battered spouse who keeps allowing the same maniac to move back in because he promises that he'll never "do it" again.
And how many judges rule in favor of the batterers... to women and nature... giving these maniacs a chance to strike again?
"History has proven that the more fossil fuel infrastructure we have, the more spills and leaks we’ll see — whether it’s Deepwater Horizon in the Gulf, the Exxon Valdez in Alaska, or the Santa Barbara oil spill almost exactly one year ago at Refugio State Beach in California."
Add in the Niger Delta and the recent spill in the Andes that will impact the Amazon.
