sentences:  In an act of appeasement to the West Harlem community for the faulty operating of the sewage plant and occupation of limited open space, the state constructed a 28-acre state park known as the Riverbank State Park on top of the sewage plant in 1993.However, fumes and odors continued to seep out of the plant affecting local neighborhoods.Today the North River Sewage Treatment Plant is continuing to improve their facility and upgrade to meet higher air quality standards.
