Two petroleum vessels collided near the Ennore port on 28th of January, 2017. It is known that approximated 32,813 tonnes of oil was spilled into the coastal waters of the Bay of Bengal. The clean up operation continues. This portion of the coast is also one of the dwindling global nesting sites of the vulnerable Olive Ridley Turtle, which returns annually between January and April to a stretch of North Tamil Nadu beaches to nest.
