EPA has issued its proposed plan:

Furthering the progress toward cleaning up the Ringwood Mines and protecting the surrounding community, EPA restored it to the National Priorities List because contaminated material was discovered since the site was originally taken off the list.

The 500-acre Ringwood Mines/Landfill Site is located in a historic iron mining district in the Borough of Ringwood, Passaic County, New Jersey. Site features include abandoned mine shafts and pits, inactive landfills and open waste dumps. During the late 1960s and early 1970s, the site was used for the disposal of paint sludge and other waste generated at the Ford Motor Company's Mahwah facility. The site was originally added to the National Priorities List of abandoned hazardous waste sites in 1983.

Between 1984 and 1988, Ford, with EPA oversight, investigated the nature and extent of contamination at the site. The results of this investigation prompted EPA to order Ford to excavate and dispose of paint sludge identified at the site, and to require Ford to monitor ground water and surface water on a long-term basis. Ford performed cleanup work at the site in 1987-1988, removing 7,700 cubic yards of paint sludge and soil. In 1990, Ford removed approximately 600 cubic yards of paint sludge as well as 54 intact and crushed drums.

Ground water monitoring conducted during the early 1990s showed that ground water contaminants were detected sporadically and at lower levels since the paint sludge had been removed from the site. EPA deleted the site from the National Priorities List in 1994, based upon a determination that all appropriate cleanup actions had been implemented.

In 1995, 1998 and in 2004, additional pockets of paint sludge were discovered at the site, prompting further cleanup actions. Ford, under EPA direction, is currently excavating the paint sludge. Since December 2004, an additional 8,600 tons of paint sludge and soil have been removed from the site as part of the ongoing cleanup effort. Furthermore, Ford has entered into an agreement with EPA to conduct a comprehensive reinvestigation of the site, to ensure that all remaining wastes are identified. EPA is currently overseeing the reinvestigation of the site, which began in December 2004 and is ongoing.
