The comment period on the public health assessment has been extended to July 31st
ATLANTA - The Agency for Toxic Substance and Disease Registry has extended the public comment period for the Midnite Mine public health assessment until July 31, 2007.
For nearly thirty years, the Midnite Mine site, located on the Spokane Indian Reservation in Wellpinit, WA, was an open-pit uranium mine. Future studies later revealed the presence of several contaminants including heavy metals, such as arsenic, cadmium, manganese, uranium, and radiation from decay products of uranium. Currently, the Midnite Mine site is being addressed under EPA's Superfund program.
In ATSDR's report, called a public health assessment, which includes ATSDR findings, as well as recommendations, concludes that radiation and radionuclides related to the Midnite Mine site are not expected to cause harmful health effects to those who occasionally visit the mine and nearby areas.
A separate health assessment, scheduled to be released at a later date, will address possible exposure to toxic metals at the location.
The agency used available data in determining whether exposure to radiation and radioactive contaminants in surface soil, sediment and surface water could be a hazard to human health.
Specific findings include:
- Radionuclides in waste rock, ore, protore and surface soils do not pose a significant health hazard for infrequent visitors.
- Radionuclides in surface water, including Blue Creek, do not pose health hazards for infrequent visitors, but the water should not be used for drinking.
- If land uses at and near the site changes to residential or other more frequent use, exposure to radiation and radionuclides in groundwater may be a health concern.
The assessment is available for public comment and review now through July 31. The public comment period is an opportunity for residents to review and comment on agency findings noted in the assessment. The assessment can be viewed at:
