Revitalize Dunkirk collaborated with National Fuel for its annual citywide spring cleanup event Monday afternoon.

Volunteers checked in at a tent set up by Revitalize Dunkirk at the City Pier, to sign a waiver, choose a work location and pick up supplies.

They did spring cleanup work at the pier, Bicentennial Park across from Dunkirk High School, the Janice Slaton Memorial Garden at Sixth and Main streets, and on the 100 and 200 blocks of Central Avenue.

National Fuel workers, who reportedly got a half-day off to participate, were distinctive in bright orange T-shirts.

The Dunkirk cleanup was part of National Fuel’s “Days of Doing,” an annual three-day companywide event featuring approximately 2,300 hours of volunteer service across the utility’s New York and Pennsylvania service territory.

There are two Days of Doing events set for Wednesday in the Jamestown area. Volunteers will help “beaverproof” trees along the Chadakoin River to prevent the beaver population from disturbing the trees. At the Audubon Community Nature Center beginning at 1 p.m., volunteers will assist with the center’s spring cleanup, collecting trash along Route 62.
