1. (a) A site shall be considered acceptable for unrestricted use only if:

   1. (1) The residual radioactivity that is distinguishable from background radiation results in a total effective dose equivalent (TEDE) to an average member of the critical group that does not exceed 0.25 millisievert (25 mrem) per year, including that from groundwater sources of drinking water; and
   2. (2) The residual radioactivity has been reduced to levels that are as low as reasonably achievable (ALARA), taking into account consideration of any detriments, such as accidental deaths, expected to potentially result from decontamination and waste disposal.

2. (b) Specific licenses, including expired licenses, shall be terminated upon written notice to the licensee only when DHHS/RHS determines that:

   1. (1) Radioactive material has been properly disposed;
   2. (2) Reasonable effort has been made to eliminate residual radioactive contamination, if present;

   3. (3) Documentation is provided to DHHS/RHS that:

      1. a. A radiation survey has been performed which demonstrates that the premises are suitable for release in accordance with DHHS/RHS requirements; or
      2. b. Other information submitted by the licensee is sufficient to demonstrate that the premises are suitable for release in accordance with DHHS/RHS requirements; and
   4. (4) Records required by He-P 4030.10(n)(6) to be submitted to DHHS/RHS prior to license termination have been received by DHHS/RHS.
