The Casmalia Resources Superfund Site (CRSS) is an inactive hazardous waste management facility located in the northwestern
corner of Santa Barbara County, California. The facility opened in 1973 and was used to treat and dispose of acids, bases,
organic solvents, pesticides, and oil drilling sludges. The facility stopped receiving wastes in 1989 and was subsequently
placed on the National Priorities List in 2001. Community health concerns relating to the facility began in 1984 when the
elementary school in Casmalia was closed down due to suspicion of odors emanating from the facility. Letters from community
members stemming from this event are included in the collection. The collection also includes several studies initiated by
the county and state in the mid-1980s that investigated the impact of the facility on the local communities in Casmalia, Tanglewood,
Orcutt, and Santa Maria. The collection contains Grand Jury hearings documents, community and governmental public hearings
and 501 hearings. In addition to the public hearings, there is testimony in the form of correspondence from community members
regarding the physical and emotional impact from exposure to contaminated air. Also included are laboratory reports for the
testing of ground water, sulfur gas, pesticides/solvents, and air pollution. There are reports from various governmental agencies
such as the state of California Department of Food and Agriculture, California Department of Health Services (CDHS), and Department
of Health Services (DHS) as well as consent decrees and compliance requirements from the Environmental Protection Agency (EPA).
Similarly, there are investigation reports from the following companies: Woodward-Clyde Consultants, Canonie Environmental,
and ICF Kaiser.

The Casmalia Resources Superfund Site, formerly the Casmalia Resources Hazardous Waste Management Facility, is an approximately
252-acre, inactive commercial hazardous waste treatment, storage, and disposal facility located in Santa Barbara County, California.
This Site is located 10 miles southwest of the City of Santa Maria, 1.2 miles north of the Town of Casmalia, and four miles
from the Pacific Ocean.
Between 1973 and 1989, the Site accepted approximately 5.6 billion pounds of waste into 92 waste management or treatment facilities.
These facilities included landfills, ponds, shallow wells, disposal trenches, and hazardous waste treatment units. During
its operational history, more than 10,000 businesses and government entities sent commercial hazardous waste to the Site.
The waste material accepted at the Site included sludges, pesticides, solvents, acids, metals, caustics, cyanide, and nonliquid
polychlorinated biphenyls (PCBs). The facility owners and operators were Casmalia Resources, Hunter Resources and Kenneth
H. Hunter, Jr.
Facing multiple regulatory enforcement actions, the facility's owners and operators stopped accepting shipments of waste material
in 1989. In 1991, the owners and operators abandoned any further efforts to properly close and clean up the Site. At that
time, conditions at the Site presented imminent and substantial endangerment to human health and the environment. From 1992
to 1996, the United States Environmental Protection Agency (EPA) used Superfund authorities to take emergency actions to stabilize
the various waste management or treatment facilities on the Site. These actions included installing and operating systems
for collecting, treating, and disposing of contaminated subsurface liquids, controlling the flow of storm water, and stabilizing

Scope and Content
The collection consists primarily of numerically arranged binders with plans, briefs, public hearings, permits, site investigations,
laboratory results, medical records, and reports relating to the Superfund response action to the Casmalia Resources Hazardous
Waste Management Facility. Also included are U.S. Environmental Protection Agency administrative records and indexes, as well
