This gas cost a city worker more than $100 a gallon.

James Meloy, an air-pollution inspector with the Department of Environmental Protection, has agreed to a one-month suspension that will cost him $5,228 for using a government gas card to fill his daughter’s car on 10 occasions.

Meloy scored $200 worth of free fuel with his department-issued card from January 2013 through April 2014, according to the Conflicts of Interest Board, which ­imposed the punishment.

Now he’ll be docked more than 25 times as much. He’ll also be on probation for two years.

In another settlement with the ethics board, a former aide to the Queens borough president was fined $2,000 for assigning himself to join a dance troupe that got a free trip to Colombia.

Former Beep Helen Marshall had tasked Pablo Romano with picking a local dance group to represent the borough at the 30th annual “International Week of ­Bolivarian Culture” in July 2010.

He included himself on the seven-day trip paid by the Colombian government.
