The Delatte Metals site is located in Tangipahoa Parish, about 2.5 miles southeast of Ponchatoula, Louisiana. The site includes the former Delatte Metals, Inc. facility, the abandoned North Ponchatoula Battery (NPB) facility and nearby residential areas. The former facility properties occupy about 19 acres. The total area of the site, encompassing both on-facility and off-facility areas, is about 57 acres. While in operation, both facilities processed spent lead-acid batteries and smelted lead plates from the spent batteries into lead ingots. Site operators discharged battery acid into an unlined pond on the north side of the site. Facility operations and waste disposal practices contaminated soil, sediment, surface water and groundwater with lead. Following cleanup, EPA took the site off the Superfund program�s National Priorities List (NPL) in 2005. Operation and maintenance activities are ongoing.
