About 4,000 gallons of insulating fluid leaked into waters around Island Park before PSEG Long Island staunched the flow with a temporary repair this week, a company spokesman said Friday. The nonconductive liquid, called dielectric fluid, is used to insulate high-voltage power lines encased in pipes.

"The leak has now been stopped," said PSEG Long Island spokesman Jeffrey Weir. Weir said the fluid is nontoxic.

The power line was de-energized Monday evening when they first discovered the leak, he said. Tuesday morning the company located the source of the leak, and began testing the structural integrity of the line. Weir said he did not know the leak's exact location.

PSEG Long Island made a temporary repair and plans to run return power to the line after making a permanent repair at some time, he said. Cleaning up the fluid could take up to one or two weeks, he said.

"The remediation work has been ongoing and representatives from the Coast Guard and [New York State] Department of Environmental Conservation are on-site to monitor the crews," he said.

Shutting down the power line did not cause any power outages, he said.

In January, a high-voltage cable owned by the New York Power Authority was discovered leaking the same kind of fluid in Long Island Sound.
