Ford Motor Company continues to address concerns raised in connection with Ford's prior disposal activities in New Jersey, including the adequacy of the prior investigation and cleanup of waste disposed by Ford. The Ringwood site was used for decades for the legal and illegal disposal of a wide variety of wastes by the Borough of Ringwood and other parties. Ford used the site to dispose of waste materials (primarily cardboard, wood wastes and paint sludge from the former Mahwah Assembly Plant) from 1967 to the middle of 1971. Ford previously participated in remediation activities at the site in the 1980s and 1990s. In September 2004, Ford entered into an Administrative Order on Consent and Settlement Agreement (AOC) with the U.S. Environmental Protection Agency regarding additional environmental activities at the Ringwood site. The EPA also requested the Borough of Ringwood's assistance in completing work at the site, and the EPA issued a Unilateral Administrative Order to the Borough regarding the Ringwood site. Ford is conducting further remedial work at the site pursuant to the AOC, all under the direction of the EPA and the New Jersey Department of Environmental Protection. It is anticipated that a new AOC will be signed later this year that will split the site into different operable units. The AOC will require Ford and the Borough to conduct feasibility studies and remedial designs for each of the operable units. Construction of the final remedies may begin in 2011.
Ford's Atlanta Assembly Plant ceased operations on October 27, 2006. The property was then sold to Jacoby Development, Inc. (JDI) in June 2008. JDI completed demolition and soil remediation activities at the site under Georgia's Hazardous Site Reuse and Redevelopment Act and received a Limitation of Liability letter dated October 23, 2009. As part of the property sale, Ford retained responsibility for groundwater remediation.
In January 2009, the Georgia Environmental Protection Department (GEPD) approved Ford's Corrective Action Plan for groundwater remediation. The groundwater remediation work was then initiated with a pilot test to evaluate the efficacy of in-situ groundwater treatment by injecting sodium persulfate (a strong oxidant) into the ground via multiple injection wells. The groundwater data collected following the pilot test showed that while the sodium persulfate was capable of degrading hydrocarbons in the groundwater, the injection approach for treatment would likely not be able to meet remedial goals because of the complex hydrogeological conditions encountered at the site.
With the GEPD's approval, Ford selected a more aggressive remediation alternative. In October 2009, Ford initiated remedial activities to excavate to the groundwater table in two areas (Areas #1 and #2) and directly mix the sodium persulfate into the saturated zone. As of January 2010, this remediation mixing had been completed in Area #1 and was approximately 50 percent complete in Area #2. It is expected that the mixing in Area #2 will be completed in the second quarter of 2010, with only ongoing groundwater monitoring remaining.
