A Republican candidate vying to take on Staten Island Rep. Mike McMahon often touts his work as a senior adviser for an environmental firm — but his family’s oil and fuel firm has had a string of spills in the Gowanus Canal, records show.

Michael Allegretti, 31, is currently a climate lobbyist who focuses on clean energy — while the family business he’s heir to and owns a stake in, Bayside Fuel Oil, has been cited for oil spills in the canal.

Allegretti said he saw nothing incongruous about his job and his family business, saying, “I think it’s a perfect example of the type of people we need in government. I’m trying to figure out what we do next as a country [regarding clean energy].”
