Annual Site Environmental Report
Each year, Idaho National Laboratory (INL) prepares an Annual Site Environmental Report (ASER) in compliance with DOE Order 231.1B, Environment, Safety, and Health Reporting, as required by the U.S. Department of Energy (DOE). This report is prepared to inform the public, regulators, stakeholders, and other interested parties about INL’s environmental performance. It summarizes environmental data, the performance of the environmental management system, and INL’s compliance with applicable DOE, federal, state, and local regulations.
Environmental monitoring has been conducted at the INL Site since 1951.
The ASER is published by October 1 each year for the preceding calendar year. The latest reports are available in PDF format. Please note that these files are large and may take some time to download.
2023 Idaho National Laboratory Annual Site Environmental Report
The 2023 Idaho National Laboratory Annual Site Environmental Report is an overview of environmental management activities conducted on and in the vicinity of the INL Site from Jan. 1 through Dec. 31, 2023.
This report includes:
- Effluent monitoring and environmental surveillance of air, water, vegetation, biota and agricultural products for radioactivity. The results are compared with historical data, background measurements and/or applicable standards and requirements in order to verify that the INL Site does not adversely impact the environment or the health of humans or biota.
- A summary of environmental management systems in place to protect air, water, land and other natural and cultural resources impacted by INL Site operations.
- Ecological and other scientific research conducted on the INL Site which may be of interest to the reader.

Program Areas
Environmental Monitoring
The lab’s Environmental Monitoring program performs constant monitoring to check for these contaminants and ensure that the environment is safe for people, wildlife and vegetation. The team collects environmental samples at the desert Site and surrounding areas.
Natural Resources
The INL desert Site consists of 890-square miles of land and is a critical component to the Department of Energy-Idaho’s understanding of environmental resources in southeast Idaho. INL has a natural resources team that provides ecological support for vegetation and wildlife at INL.
Environmental Publications
INL publishes a variety of reports as part of its commitment to environmental stewardship and full compliance with environmental protection laws and regulations. These reports ensure that the lab’s mission can be achieved with little to no impact on the environment, wildlife and vegetation.
