UNITED STATES ENVIRONMENTAL PROTECTION AGENCY

OFFICE OF 

SOLID WASTE AND EMERGENCY RESPONSE 

Mr. Robert Stern, Director 

Office of Environmental Guidance (EH-23) 

U.S. Department of; Energy 

Washington, D.C. j 20585 

Dear Mr. Stern: | 

! 

The U.S. Environmental Protection Agency's (EPA) Emergency Response 

Division (ERD) is currently evaluating issues and options for adjusting 

the statutory radionuclide reportable quantity (RQ) under section 102 of 

the Comprehensive Environmental Response, Compensation, and Liability Act 

of 1980 (CERCLA or Superfund). Under the present law, anyone who releases 

one pound of any radionuclide into the environment (land, air, water/ground 

water) must report this release to the National Response Center, unless the 

release is excluded from the definition of "release" under CERCLA section 

101(22)(C) or is federally-permitted within the meaning of that term as set 

forth in section 101(10) of the Act. Because the EPA does not believe that 

the one pound RQ for radionuclide releases is appropriate, the Agency has 

initiated regulatory development efforts to adjust the RQ. Carl Welty on 

your staff is a member of the interagency Work Group for this regulatory 

development effort. Carl has been extremely responsive and has provided 

valuable information and recommendations in the Radionuclide RQ Adjustment 

Work Group. 

In order to further assist us in this effort, we are asking the 

Department of Energy (DOE) to provide us with certain data. Specifically, 

we are interested in receiving summary data on reports of accidental 

releases of radionuclides from DOE facilities over the past three years. 

Key parameters in these data include the date of release, the particular 

radionuclide and quantity released, and, if possible, whether or not an 

emergency or remedial response was required. Any indication of the permitted or acceptable release levels for these radionuclides would also be 

useful for comparison. Such data would help in identifying individual 

radionuclides for which an RQ may be'useful, the distribution in size of 

radionuclide releases, and the likelihood of government response once a 

release notification has been made. 
P.3 

I In addition, to the extent that this information is available and is 

not classified, we also request that DOE provide data which approximates 

the total quantities of different radionuclides used or in inventory under 

DOE contractor control. Data on radionuclide quantities would be helpful 

in estimating the likelihood of a release of certain radionuclides. Because 

the likelihood of release is also dependent on the radionuclide form, any 

estimates of how much of the DOE radionuclide inventory is in different 

forms (e.g., sealed sources, liquids, and gases) would also be valuable. 

I I would like to take this opportunity to thank DOE for its continued 

participation and support. If you have any questions or comments concerning 

this request, please call Barbara Hostage or Nancy Parkinson on my staff at 

382-2190. 

I ;ly yours, 

imothy Fields, Jr. 

Director 

Emergency Response Division (Wh-548/B)
