A cargo vessel carrying salt has been secured to the upper wall at Snell Lock in Massena this morning after a minor oil leak Wednesday afternoon, according to the St. Lawrence Seaway Development Corp.
Seaway lock crews detected a light sheen of oil at about 3:30 p.m. Wednesday as the vessel Captain Henry Jackman departed the Eisenhower Lock downbound, the Seaway said in a news release.
Boom was deployed around the vessel as a precautionary measure and navigation was suspended Wednesday between 6:30 p.m. and midnight while an assessment was conducted by both U.S. Coast Guard and Seaway inspectors.
Three upbound and one downbound vessels were delayed because of the spill.
Inspection personnel from the Coast Guard, U.S. and Canadian Seaways, a representative of the ships owner and the vessels classification society are on board investigating the source of the leak.
