Exxon Mobil's top lawyer said Wednesday that a heavily criticized $225 million pollution settlement with New Jersey was reasonable and that the nearly $9 billion initially sought by the state shouldn't be used as a barometer because it was calculated using faulty methodology. The settlement announced in March has drawn criticism from environmentalists and lawmakers in both parties who have said the state should have waited for a judge's ruling instead of settling for what they have a characterized as pennies on the dollar.
