1.1.1 Incident Category
Emergency Response Action - Placement of asbestos cement pipe (ACP) contaminated fill material and discarding ACP along public rights-of-way (ROWs).
1.1.2 Site Description
ACP contaminated fill material was placed at several residential, religious, and public properties throughout the City of Orofino and nearby Clearwater County. ACP was also discarded along public rights-of-way.
1.1.2.1 Location
Orofino is a rural community located in the North Central Region of Idaho along Orofino Creek and the north bank of the Clearwater River. The population is approximately 3,300, and the city is the county seat for Clearwater County. The approximate latitude and longitude for the Site is 46º28.41’11”N and 116º15.10’57”W.
1.1.2.2 Description of Threat
The elevated concentrations of chrysotile asbestos discussed in Section 1.1.3 indicate that the potential for inhalation exposures exists. There is not a known safe level or period of asbestos exposure. Exposure to airborne friable asbestos may result in a potential health risk because persons breathing the air may breathe in asbestos fibers. Continued exposure can increase the amount of fibers that remain in the lungs. Fibers embedded in lung tissue over time may cause serious lung diseases, including asbestosis, lung cancer, or mesothelioma.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
Random grab samples of ACP analyzed using Polarized Light Microscopy (PLM) and Transmission Electron Microscopy (TEM) showed asbestos concentrations ranging from 7% to 20% chrysotile; soil samples showed 0.25% and 0.75% chrysotile; and one transite siding sample showed 3% chrysotile.
The analytical results indicate that asbestos fibers, ACP, and transite siding are present on the ground at various locations. With time and exposure to damaging mechanical forces and weather, the ACP and transite siding can continue to become friable thus releasing asbestos fibers to the environment.
