From 1955 through 1970, operations of a manufacturer of solid rocket fuel contaminated the soil at the facility now know as the Denville Technical Park. This contaminated soil is a source of groundwater contamination and has contaminated the Rockaway Township Wellfield. The rocket fuel manufacturer is defunct but a successor, the Respondent, has agreed to assume responsibility for remediating soil and groundwater contamination at the Denville Technical Park facility and paying EPA future non-RD/RA oversight costs. The Respondent has agreed to a series of demand letters, and its predecessors paid all EPA past costs that were not RD/RA oversight costs (The Third Circuit has ruled that parties are not liable under CERCLA for those costs). In this agreement, the Respondent agreed to pay future non-RD/RA oversight costs and to waive a possible future Statute of Limitations defense if the law should change of EPA must require additional work.
