Pittsburgh Metal & Equipment operated a smelter from the early 1960s to the late 1990s. The operation resulted in metals contamination in the soil at the Site. EPA conducted a removal action at the Site and is seeking reimbursement from all of the parties. This proposed action relates to the de minimis parties at the Site. Further, certain of the de minimis parties did not timely submit responses to the 104(e) Information Requests and penalties are being sought for those.
