Few would argue that first responders earn every penny of their salaries. But some are wondering if the benefits may be too lucrative after a New York Port Authority Police Department sergeant reportedly raked in $166,000 last year in overtime pay.

The New York Post reported that Sgt. Edwin Rivera, a 16-year veteran of the force, earned a total of $273,946 in 2011, thanks to hundreds of hours of overtime -- more than any other PAPD employee -- on top of his base salary of $107,911.

According to the newspaper, the 43-year-old Staten Island resident supervises officers who patrol the city's PATH train line, and averages about 40 hours of overtime each week.

The Post reported that the overtime comes as a result of a shortage of sergeants at the PAPD.

However, 2011 wasn't the only overtime-rich year that Rivera has had.

According to SeeThroughNY, a government transparency site, in 2010, Rivera earned $259,304, including $152,193 in overtime. In 2009, he earned $228,460, with $126,251 in overtime.

In comparison, Rivera's boss, PAPD Superintendent Michael Fedorko, earned $215,098 last year, while N.Y. Gov. Andrew Cuomo earned a salary of $179,000.

A PAPD spokesperson told the Post that the agency has succeeded in curbing OT hours by an overall 14 percent during the first quarter of 2012.
