Health consultation: Asbestos exposures at Oak Ridge High School, 1120 Harvard Way, El Dorado Hills, California, EPA Facility ID: CAN000906055

Agency for Toxic Substances and Disease Registry 2006

Abstract  Oak Ridge High School is located at 1120 Harvard Way in El Dorado Hills, California, about 30 miles northeast of Sacramento, in El Dorado County. Naturally occurring asbestos has been identified in rocks and soils on and around school property, and a vein of asbestos was disturbed during construction of a soccer field in 2002. A community member, who had been active for several years in voicing concern over asbestos exposures in the area, asked the Agency for Toxic Substances and Disease Registry (ATSDR) to evaluate the public health implications of current and past asbestos exposures of students and staff at the high school. In this public health consultation, ATSDR reviews available environmental data and potential exposure pathways to determine whether adverse health effects are possible from past or present asbestos exposure at Oak Ridge High School and recommends actions to prevent, reduce, or further identify the possibility for adverse health effects. ATSDR has also received numerous reports of health-related concerns about the area surrounding the high school and other areas with naturally occurring asbestos. The US Environmental Protection Agency (EPA) is currently collecting and analyzing data on asbestos levels in other areas of El Dorado County, and ATSDR will address those pathways in a subsequent health consultation.

Health Hazard Evaluation Report No. HETA-87-392-2099, Loral Systems Group, Akron, Ohio

Driscoll RJ 1991

Abstract  In response to a request from the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (UAW), an evaluation was undertaken of possible health hazards at the Loral Systems Group (SIC-3728) located in Akron, Ohio. Concern was voiced about possible asbestos (1332214) exposure. The company produces wheels and brakes for civilian and military aircraft and currently employs about 1560 persons at the Akron facility. At the time of the study there were about 2300 living retirees. The precise number who had worked in one of the four areas of particular interest was unknown. Of the 166 persons found eligible for inclusion in this health hazard evaluation (15 or more years of potential asbestos exposure in at least one of the four identified programs and still residing in Ohio), 129 participated in a medical evaluation consisting of a chest x-ray, pulmonary function test, and completion of a questionnaire to detail medical and prior work histories. Abnormal pulmonary function results were noted in 39 of these individuals of whom 30 demonstrated an obstructive pattern, three a restrictive pattern, and six both an obstructive and restrictive component. Nonsmoking participants were more likely to report chronic cough, chronic phlegm, and chronic bronchitis than comparisons.

Health consultation: Former California Zonolite/W.R. Grace & Company site: 5440 West San Fernando Road Glendale, Los Angeles County, california: USEPA facility ID: CAN000905898 and CAN000905894

Agency for Toxic Substances and Disease Registry 2007

Abstract  ATSDR evaluated the former California Zonolite/W.R. Grace & Company site in Glendale, California, because more than 120,000 tons of asbestos-contaminated vermiculite were shipped to the site and expanded by exfoliation. Commercial exfoliation of vermiculite is a process of heating uniformly graded pieces of vermiculite in a furnace to expand or pop it into lightweight nuggets. The California Zonolite/W.R. Grace & Company facility operated from 1950 to 1977. The site consists of 2.75 acres of land on the north side of greater Los Angeles. Land use around the site is commercial, light industrial, and residential. The closest residential area is located 500 yards to the east. 1990 census data indicate 1,748 people lived within 1 mile of the site during the decade after vermiculite processing ceased. While the facility was operating, workers at the facility and members of their households were exposed to asbestos from the processing and handling of asbestos-contaminated vermiculite and waste rock. Sufficient site- and process-specific information is available to consider these exposures a public health hazard. On the basis of the information available, ATSDR estimates that from 70 to 150 former workers were exposed during the time the plant operated.
