WATKINS GLEN, N.Y. — A Houston company says it’s selling its salt mine on the shore of Seneca Lake, but will proceed with a propane storage project that’s opposed by Finger Lakes winemakers and others in the region.

Crestwood Equity Partners announced Tuesday that it’s selling U.S. Salt in Watkins Glen to Kissner Group Holdings for $225 million. But it’s preserving its right to store propane and natural gas in nearby depleted salt caverns.

A permit application for the storage project has been before the Department of Environmental Conservation since 2009. Opponents say it threatens the local environment and the Finger Lakes tourism and wine industries. Crestwood says the project will improve the propane supply in the Northeast.

Kissner said the U.S. Salt refinery in Watkins Glen will remain in operation.
