900 N POTRERO GRANDE DR
The Operating Industries, Inc. (OII) Landfill site is located approximately 10 miles east of downtown Los Angeles at 900 Potrero Grande Drive in the City of Monterey Park. The Pomona Freeway divides the 190-acre site into two parcels namely: South and North Parcels. The Monterey Park Disposal Co. began landfilling operations at the site in 1948, and in the 1950s Operating Industries, Inc. purchased the landfill and continued operations. A.H.A.S., Inc. is the current owner of record of the North Parcel, and Operating Industries, Inc. is the current owner of record of the South Parcel. Over the life of the landfill, many wastes have been disposed there. The South Parcel, approximately 145 acres in size, received the majority of wastes including residential and commercial refuse, liquid wastes, and various hazardous wastes. The North Parcel is about 45 acres in size, and approximately 10 acres of the western side of the North Parcel were used as a landfill and received primarily construction and debris (C&D) waste. The majority of the C&D waste on the North Parcel is composed of wood, glass, metal, paper, cardboard, brick, asphalt, concrete, and plastic. In January 1984, the State of California placed OII on the California Hazardous Waste Priority List. The landfill stopped accepting wastes and was closed in late 1984. The U.S. EPA proposed OII to the NPL in the same year and began conducting studies and taking actions to protect the local environment and those who live near the site. Approximately 23,000 people live within three miles of the site, and 2,100 people live within 1,000 feet of the landfill.
