Two weeks ago, a barge headed for a power plant on Buzzards' Bay ran aground on some rocks. Four million gallons of number six fuel oil spilled and tarballs washed ashore all along the South Coast of Massachusetts.
Something similar could happend in the Pisquataqua River, where barges unload their cargo into gigantic heating oil storage tanks.
But a group of oil and energy companies say they are prepared to contain a spill and protect Portsmouth's Great Bay estuary. NHPR's Raquel Maria Dillon has more.
