Mr. Fey developed solutions for air-management problems, and then contacted other government officials, industrial-plant representatives, and the public to solicit testimony on the proposed legislations. Once the rules were in place, he checked to see if they were working.
From September 2012 to February 2013, he also was chief of the Air Monitoring Network, a technical group that supports air-quality testing for the city.
He earned his undergraduate degree in electrical engineering from Villanova University, and two master's degrees, one in engineering and the other in business administration, from Pennsylvania State University.
While at Villanova in 1990, he helped build a SolarCat - a solar-powered race car.
"Roger was the most amazing dad, husband, son, brother, brother-in-law, neighbor, and friend, who also found time to be active in the community," his wife said.
He was the "go-to guy" in the neighborhood for Somerton Spartans Athletic Team sports. He coached soccer, baseball, and T-ball and also was the den leader for Boy Scout Pack 367.
Surviving, beside his wife, are sons Brandon Roger and Tyler Joseph; his mother, Helen; and a brother.
Services were Saturday. Burial was private.
