The Douglas Road Landfill site is located in St. Joseph County just north of Mishawaka, Indiana. The site is approximately 16 acres in size and is located near the northwest corner of Douglas and Grape Roads. The site is bound to the north by the Indiana State Toll Road, to the east by a shopping center and an apartment complex, to the south by residential properties and to the west by agricultural land.

In the early 1950s, the property was excavated and gravel on site was used for the construction of the interstate highway. Uniroyal Plastics, Inc. (Uniroyal) leased the gravel pit and used it as a repository for plant wastes between 1954 and 1979. From 1954 to 1971, solvents, fly ash, paper, wood stock, rubber and plastic scrap were disposed of at the landfill. Only fly ash was disposed of from 1971 to 1979. In December 1979, the site was closed to compliance with impending RCRA regulations pertaining to the operation of a landfill.

According to the information provided by Uniroyal, approximately 302,400 gallons of RCRA hazardous waste were disposed of at the landfill. Liquid wastes included methyl ethyl ketone, acetone, tetrahydrofuran, toluene, hexane, and xylene. Historical aerial photographs of the landfill indicate several pits containing liquid that may have been used for disposal; the largest (and longest used) was in the central area of the landfill.

The landfill was proposed for inclusion on the NPL on March 31, 1989, and placed on the NPL on June 10, 1989. In September 1989, the State of Indiana and Uniroyal signed a consent decree, in which Uniroyal agreed to perform a RI/FS at the site. Before completion of this work, Uniroyal filed for bankruptcy and discontinued work at the site.

A RI/FS was performed including activities to determine the nature and extent of contamination at the site and evaluating the feasibility of various remedial alternatives to clean up the site. The RI/FS determined that soil and waste materials and area groundwater had become contaminated because of past disposal activities at the Site.

This Record of Decision (ROD) addresses contaminated soil and waste materials. These areas were determined to pose risks to human health and the environment due to dermal contact or incidental ingestion of site surface soils.
 
Remedy:  The selected remedial action for this site includes several components. The first component is to install a Composite Barrier Cap with a GCL Soil Barrier Layer. The second component is to collect and dispose of landfill gas. The third component is to dig perimeter ditches to collect surface water drainage. The fourth component is to establish groundwater and source monitoring to ensure that the goals of this action are met.
