TENORM regulation development

Technologically enhanced naturally occurring radioactive materials (TENORM)

Produced when activities such as uranium mining or sewage sludge treatment concentrate radioactive materials that occur naturally in ores, soils, water or other natural materials.
 
In 2018, the Colorado State legislature passed a bill (SB 245) that gave CDPHE the authority to promulgate rules for the safe management of Technologically Enhanced Naturally Occurring Radioactive Material (TENORM). The bill requires the Department to:
  • Review TENORM residual management and regulatory limits from other states.
  • Prepare a report that considers background radiation levels in the state, waste stream identification and quantification, use and disposal practices, current engineering practices, appropriate test methods, economic impacts and data gaps.
The department hired Rule Engineering to research and prepare the report required by SB 245.
