This bill, H.R. 3426, would amend the Clean Water Act to require the closure of (1) any oil storage or processing facility that is within one mile of 100 or more dwellings and has had two or more discharges within a 10 year period, or (2) where the facility is the source of groundwater contamination affecting 100 or more residential units. Closure would still be required where the discharge resulted from an act of God, war or negligence by the federal government.
