The CLTL Bridgeport Terminal is located in Logan Township, Gloucester County, New Jersey, approximately two miles south of the Delaware River and one mile east of the town of Bridgeport. The CLTL property encompasses approximately 31.4 acres. It includes an active terminal used for the dispatching, storing, maintaining and cleaning tanker trucks and trailers; fallow farmland adjacent to the terminal; and wetlands (Cedar Swamp) bordering the terminal to the east and southeast. Moss Branch Creek drains portions of Cedar Swamp into Cooper Lake, which is located approximately 1,000 feet north of the CLTL terminal. Commercial infrastructure at the CLTL property includes the terminal building, an enclosed wastewater settling tank building, and a concrete wastewater holding tank. Former subsurface structures include several earthen settling and aeration lagoons which have been backfilled and graded.
In operation since the early 1960s, CLTL transports chemical commodities, some of which are classified as hazardous in bulk quantities. Past wastewater handling and disposal practices at the CLTL Site have resulted in organic and inorganic contamination of soil, ground water and the adjacent wetlands. Prior to 1975, wastewater generated by the tanker-truck washing and rinsing operations was impounded in a series of unlined settling and/or aeration lagoons and subsequently discharged to the adjacent wetlands. In 1975, the lagoons were taken out of service when CLTL was required to install a wastewater containment system at the terminal. In 1977, liquid and sludge in the primary settling lagoons were removed and backfilled with fill and construction debris. The aeration and final settling lagoons were drained, but no lagoon materials were removed prior to backfilling. In 1982, CLTL excavated visible sludge and contaminated soil from the former primary settling lagoons to an approximate maximum depth of 12 feet below the surface, and the excavation was backfilled with sand.
In 1985, the U.S. Environmental Protection Agency (EPA) added the CLTL Site to the National Priorities List of Superfund sites.
