The U.S. Environmental Protection Agency (EPA) is conducting its fourth five-year review of the cleanup plan at the Ley Creek PCB Dredgings Subsite, located in Salina, NY.
The review seeks to confirm that the cleanup conducted at the subsite continues to protect human health and the environment.
The 4,300 foot-long area where PCB contaminated dredge spoils from the creek have been placed is bounded by Factory Avenue on the south, Ley Creek to the north, Townline Road to the east, and the Town of Salina Highway garage to the west.
Cleanup activities included excavating and disposing dredge spoil materials/soil containing more than 50 milligrams per kilogram (mg/kg) of polychlorinated biphenyls (PCBs), consolidating and placing a vegetative cover over PCB-containing dredge spoil materials less than 50 mg/kg, and deed restrictions to prevent activities that could potentially expose contaminated materials and to ensure the integrity of the vegetative cover.
Ley Creek flows through a highly urbanized and commercial area in the Town of Salina, just north of the city of Syracuse, NY. Many industrial wastes, including oils containing polychlorinated biphenyls (PCBs) were discharged into Ley Creek and its branches.
It is anticipated that the five-year review report for the Ley Creek PCB Dredgings Subsite will be available on EPA’s Onondaga Lake Superfund site webpage by late winter 2022.
